The ownerships are considered the Project Area, which is 5,961 acres. F. UNIT FIRE PLAN HAZARD RATING: High and Very High 1.3 Environmental Setting and Impacts A. In 2019, Governor Newsom included the Ukiah Emergency Fuels Reduction Project as one of 35 priority projects to implement immediately to reduce public safety risks for the most wildfire - vulnerable communities. Under a State of Emergency, the requirements of CEQA were suspended and environmental protections are built into the project design. CAL FIRE currently proposes to implement Phase I vegetation treatments, including maintenance and retreatment, on up to 998 acres of land on the western side of Ukiah Valley in Mendocino County. This treatment would ultimately protect approximately 5,961 acres within the Project Influence Zone, also considered the total Project Area. This includes property owned by the City of Ukiah, Mendocino County, and privately owned lands within the Russian River watershed, specifically on slopes west of the City. The project area is utilized for rural residence, agriculture, recreation, and wildlife management. This VTP project will be completed using prescribed fire as Wildland-Urban Interface (WUI) treatment for grasslands, chaparral, and understory vegetation within oak woodlands and mixed conifer habitats to create a mosaic of variously burned vegetation and islands of unburned habitat. Treating vegetation around the community of Ukiah will help to build wildfire resilience, while also improving the overall quality of the local ecosystem. Planned treatment areas are stratified across the project area. The prescribed burning conducted under this VTP will be done to meet objectives conducted under specific climatic conditions to ensure control and minimize air quality and biological impacts. These conditions will mimic air, soil, and vegetation moisture, and other conditions under which natural wildfires occur to maximize beneficial effects on the plant and wildlife communities. The primary goal of this prescribed burn is to reduce overall fuel loading to decrease the chance of catastrophic wildfires in the future. A second goal is to reintroduce fire as a natural element of the ecosystem. A third goal is to improve wildlife habitat by inducing new shoots from sprouting species to increase forage production in chaparral, with islands of unburned fuel left within burn units to provide shelter for small mammals. Grassland units will benefit from increased growth of native perennial grasses and a decrease in noxious weeds. Portions of the project site have remained fire-free for over two decades, allowing fuel accumulation to reach maximum levels. Consequently, wildlife movement within the area has been significantly reduced, and the flow of water from creeks and springs has been curtailed. All native vegetative and wildlife species present within the project area are fire -adapted. The reintroduction of fire into this ecosystem is part of the natural process. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU Vegetation communities across the entirety of the West Hills are characterized by grasslands, dense chaparral (chamise and manzanita), and mixed hardwood-conifer woodlands. Chaparral coverage varies from nearly continuous to sparse, with grassy openings and areas featuring a mixture of hardwood tree species and grasses. The chamise component ranges from pure stands to a 50/50 mix with ceanothus, manzanita, and other chaparral species along with minor amounts of herbaceous vegetation. Prescribed fire eliminates or reduces the ladder fuels that connect ground vegetation to tree canopies, making them less susceptible to severe, crown - consuming fires. It can result in a mosaic of differing successional stages of habitat that promote plant and animal diversity. Historically, chaparral fuel beds experienced fire every 15 to 20 years. These fuels attain maximum volume with a high dead fuel component when fire is absent. The presence of decadent fuels also reduces the ability of wildlife to move through the area and reduces the flow of water from creeks and springs. All vegetative and wildlife species present within the project area are adapted to fire. The introduction of fire, as part of a mosaic burn treatment of the area, will return the chaparral ecosystem to a more natural process. The project area is located within the Northern California Coast Ranges Ecological Section (M261B), and ranges in elevation from 1,140 to 3,500 feet and consists primarily of Montane Hardwood, Montane Hardwood-Conifer, grazed and un-grazed Annual Grassland, Mixed Chaparral, and Chamise-Redshank Chaparral. Areas of oak woodland are present between chapparal stands. A mosaic burn pattern in the chaparral fuel type is planned with a fuel consumption rate of approximately 60-70%. Ignitions in burn units will include both interior and perimeter ignitions. With multiple ignition sources, fire will spread at different rates and intensities and will result in mosaic burns. Where applicable, perimeter ignitions at ridgetops will be allowed to burn until spread is no longer carried by fuels and ground moisture conditions no longer support fire. This will result in ridgetop fuel breaks. The terrain consists of slopes that range from broad valleys with moderate to steep side slopes and gently sloped ridgelines. Control lines are preplanned and will be established utilizing an existing road network as much as feasible. A bulldozer may be employed to construct new control lines, fuel breaks, or re- scrape overgrown roads and skid trails down to mineral soil to ensure functionality prior to ignition. Handlines will be constructed in areas inaccessible to heavy equipment or where such use is prohibited to avoid impacts to pre-identified sensitive resources (e.g., biological, cultural, geological or other). Grading and other mechanical manipulations will be minimized. Minor road maintenance such as grading, and brushing will need to be conducted to allow access by a Type 3 Wildland Fire Engine. Mechanical vegetation removal (including the potential for mastication) and pile burning may be necessary to avoid prescribed fire impacts to resources identified for retention, especially where fuel loading i s high. Hazard tree removal and fuel reduction along roadsides may be done with hand crews or mechanically prior to burning . Targeted ground application of herbicides is also proposed. CAL FIRE will administer burn operations, except on the City of Ukiah parcels. The Ukiah Valley Fire Authority’s fuels crew will conduct operations on City-owned lands. An Incident Commander Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU (IC) will be identified by the Unit Chief to supervise the entire burn operation. The perimeters and interiors of burn units will be fired utilizing a combination of heli-torch (aerial), terra-torch (mobile) and drip-torch (on-foot). The perimeters and majority of burn units will be fired utilizing drip torches. Specific environmental parameters must be met prior to the initiation of burning and must be maintained within predefined limits (i.e. burn specifications) for burning to continue. Hourly weather reports will be conducted during the burn or as necessary if conditions change to ensure operations are within specifications otherwise the burn may be extinguished for safety reasons. Wind, fuel moisture, topography, control lines, and placement of holding resources will determine the sequence of ignitions. Backing and flanking fire will be utilized within units to ensure sufficient burned area is created for controlling a more intense head fire that may be needed to adequately consume some fuel types. Ignitions shall not occur within watercourses, and control lines will be maintained around pre -identified sensitive resources at all times. Prescribed burning is a management tool that the City of Ukiah, Mendocino County, and private landowners would like to employ with the assistance of a professional fire department. The Prescribed Fire IC will supervise holding resources and will designate a crew to monitor and patrol the burn area to ensure that spread is contained within control lines . Necessary suppression activities shall be focused on all fire outside of control lines and/or areas where fire behavior poses an escape risk. The IC may also require monitoring, patrol, and holding resources overnight. • AESTHETICS - The project area is located outside any scenic views of California’s North Coast that reside along SH 101, thus those scenic vistas will not be impacted. The proposed treatments would not occur on lands adjacent , however, public viewpoints of the project area are available from public recreation trails, adjacent residences and wineries, and SR 20. The project, including the fuel breaks, is visible from Ukiah, and since it maintains the 2019 footprint, it will not increase aesthetic impacts. Visibility of treatment areas would be limited from the highway and no vegetation would be removed immediately adjacent to the highway. Short-term vegetation charring will be noticeable but will be replaced by new plant growth during the next growing season. The degree of vegetation change is expected to be minimal and not impact the natural aesthetics or character of the landscape. The equipment, vehicles, and any vegetation treatment debris associated with the activities proposed in this project will not block or disrupt views. Although some burn units may be noticeable after treatment, the degree of vegetation change is expected to be minimal and not impact the natural aesthetics or character of the landscape. No effects anticipated. • AGRICULTURAL and FORESTRY RESOURCES – The project area consists primarily of Montane Hardwood, Douglas fir-Hardwood woodlands, Chamise Chaparral and Manzanita Chaparral. The treatment areas are primarily comprised of brush and shrub species intermixed to a lesser extent with conifer and hardwood species. No part of this project will constitute commercial timber operations. • AIR QUALITY – Burning will be performed in accordance with a Smoke Management Plan Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU approved by the Mendocino County Air Quality Management District (MCAQMD). This document contains provisions for reducing the amount and duration of potential smoke impacts. Venting height will be a minimum of 500 feet. Good atmospheric mixing and adequate transfer winds to disperse the smoke column will be necessary for a successful burn. The Smoke Management Plan also contains public notification procedures and requirements. CAL FIRE will terminate if the planned convective lift and/or planned dispersal cannot be achieved. • BIOLOGICAL RESOURCES – A query of CDFW’s Natural Diversity Database (CNDDB) was performed by the RPF consultant in June of 2022. GIS data available through BIOS website was used to extract information on listed/sensitive species containing and surrounding the project area. Data review was conducted of the project-specific biological resources, including habitat and vegetation types, and special -status plants, special-status wildlife, and sensitive habitats (i.e., sensitive natural communities and riparian habitats) with potential to occur in the project area. Based on the CNDDB query and local knowledge of the project area, biological scoping was conducted for each of the species shown as occurrences. Refer to the Environmental Checklist in Section III for scoping and subsequent impact analysis summaries. Most species of plants and animals, including listed or sensitive species, will benefit from habitat improvements that will likely result from the disturbance caused by the proposed burning. The proposed burning will mimic the disturbance caused by natural fire in this fire dependent landscape. Substantial evidence shows that habitat function of forest and woodland is reasonably expected to improve with implementation of the treatment. Historically, prior to fire suppression and logging, Douglas-fir-tanoak forests in the North Coast Range experienced fire return intervals between 4 to 6 years, which likely promoted open forests with greater cover of understory plant species. The benefit of prescribed burning on the habitat of special -status species outweighs the cost of a severe, stand - altering wildfire that would kill the forest and woodland habitat in the project area. Common species of animals that use the area include black-tailed deer, quail, turkeys, mountain lions, coyotes, squirrels, and raptors. This project should improve wildlife habitat overall for these species by improving forage through the regeneration of shrubs and an increase of native grass and forb dominated areas. The objective is to use fire in a controlled manner during appropriate weather conditions to reduce the risk of a large, intense, damaging fire that could cause significant impacts to soil, vegetation, animals, air quality, etc. General operating practices incorporated into the design of the burn plan that maintain or improve habitat function for listed wildlife species include: 1) the burn prescription shall create a mosaic of burned and unburned habitat within treatment units; 2) treatment units will occu py a small percentage of the landscape and are dispersed over a large area such that unburned refugia are maintained close to treatment units; 3) key habitat structures and locations such as nests, snags, cavity trees, basal hollows, rock caves, large and course woody debris, and overstory trees, shall be retained (and protected if necessary when the prescription would significantly alter or Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU destroy them). Fire is valuable in rare plant conservation both directly, by fostering emergence and regeneration of rare species, and indirectly, by cont rolling invasive species. Native vegetation, including endangered plants, need fire to thrive and maintain resilience. Prescribed burning is a positive management tool toward habitat recovery. A notification letter was email ed to Kate Belville of CDFW on February 19, 2024, with project description, protection measures, and project map. She was invited to share information or any concerns. A response was received from Kate Belville on February 28, 2024, with no concerns on the project. A revised letter was mailed to Merissa Hanisko of CDFW on May 20, 2025; questions and comments were received through multiple emails, which were clarified and incorporated into the project design. • CULTURAL RESOURCES – This project includes the entire City of Ukiah, County of Mendocino and private landowner’s ownerships which total 5,961 acres. This project will utilize a phased Archaeological process. An Archeological Survey Report (ASR) was completed for the currently scheduled treatment units by Kate Cahill Senior Forester, RPF #3031, NCRM, Inc. and was reviewed by Julie Rhoads MEU Forester II, RPF #2815 and CAL FIRE Archaeologist Geoffrey Hughes. A cultural records search for the Project Area (ownership) was submitted three separate times (as the project area expanded) and was received from the Northwest Information Center (NWIC) at Sonoma State University on March 09, October 27 and November 30 of 2023. There is one previously recorded historic resource site and no previously recorded prehistoric resources site. Attachment B of the ASR provides copies of correspondence with Native American tribes. The current survey effort resulted in the identification of 1 previously unrecorded isolate. If operations are planned on any additional areas during the life of this project, survey efforts will be conducted through a second phase of archaeological review. Survey methods and results will be added in an addendum to the ASR. A consultation with CAL FIRE Archeology Program will occur if sites are identified within any additional units. No impacts to cultural resources area expected. • GEOLOGY and SOILS – There are no known unstable areas or geologic hazards within the project area. Control line construction and non-shaded fuel breaks will result in the removal of all vegetation down to bare mineral soil. Non-shaded fuel breaks will range from 100- 150ft pending slope, terrain and fuels. Some or all root systems will be removed during control line construction. Control lines are long, linear features, ranging between 1 and 12 Feet in width. These long, linear features would not cause enough destabilization of an area to cause landslides, as the root systems adjacent to the control lines would remain intact. No impact is expected. A notification letter was emailed to Kevin Doherty (Senior Engineering Geologist) of the California Geological Survey-Forest and Watershed Geology Program on January 23, 2026, with project description, protection measures, and project maps. He was invited to share information or any concerns regarding potential impacts from geological hazards . As of Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU February 19, 2026, CGS recommends that if ground disturbing activities occur in areas identified as likely to contain naturally occurring asbestos (NOA) that CAL FIRE contact Mendocino County AQMD to develop an Asbestos Dust Control Plan consistent with the requirements of SPR AQ-5. • HAZARDS and HAZARDOUS MATERIALS – This project involves control line construction/maintenance, the use of prescribed fire as a treatment type, and fire suppression. These activities will employ vehicles, fire engines, chainsaws, heavy equipment, possibly helicopters, and fire ignition systems and accelerants that rely on a variety of petroleum products (e.g., gasoline, diesel, jet fuel, oil and other lubricants) which pose a health hazard to humans and the environment. CAL FIRE requires daily safety inspections and a regular maintenance plan for all equipment to ensure that equipment is safe, functional, and free of leaks. Spill kits are also kept with vehicles and equipment to contain fuel and/or hydraulic leaks should they occur. Locations used for fueling the helicopter or servicing fire ignition systems are established in areas where spills can be easily and rapidly contained (i.e., level ground) that are also outside of Watercourse and Lake Protection Zones (WLPZ) and other sensitive areas. Most fueling activities for the project will occur offsite at CAL FIRE stations. Herbicide application to target plant species will employ ground-based methods, such as using a UTV or backpack sprayer or painting herbicide onto cut stems. No aerial spraying of herbicides would occur. Herbicides will not be utilized within WLPZs or EEZs. In addition, herbicides would be applied by licensed applicators in compliance with all laws, regulations, and herbicide label instructions. No impacts are anticipated. • HYDROLOGY and WATER QUALITY – The project area lies primarily within the Gibson Creek planning watershed, with portions in the Orrs Creek, Upper Robinson Creek, and Lower Robinson Creek planning watersheds, all of which drain into the Russian River. Riparian habitat is present within the project area adjacent to streams, lakes, and ponds . All watercourses and wet areas will receive protection from ignitions and control line construction with heavy equipment. Watercourse and Lake Protection Zones (WLPZs) ranging from 50-150ft will be implemented for Class I and Class II stream s for ignitions, manual and mechanical treatments. These areas will retain at least 75% of the overstory and 50% of the understory canopy and would largely be limited to removal of uncharacteristic fuel loads (i.e., dead or dying vegetation, invasive plants). No fire ignition will occur within WLPZs, however, low intensity backing fires may enter or spread through. There will be no debris or slash generated from prescribed burn treatment s deposited into watercourses or wet areas. Equipment will not be driven in wet areas or WLPZs, except over existing roads or watercourse crossings where vehicle tires or tracks remain dry. Equipment will not be serviced in WLPZs or other wet areas that would allow grease, oil, or fuel to pass into watercourses or wet areas. Equipment limitation zones will be designated adjacent to Class III and Class IV watercourses with minimum widths of 25ft where side -slope is less than 30% and 50ft where side-slope is 30% or greater. Heavy equipment will be prohibited from traversing slopes steeper than 50%; any slopes greater than 50% that require a control line shall be constructed by hand crews. Existing roads and trails will be used as control lines as much as possible. Where lighter fuel loads exist, mow and disk lines may be used to create Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU control lines. Root systems will generally remain intact. Heavy equipment use will not occur on wet saturated soils. Minor road maintenance such as grading, improving drainage and brushing will need to be conducted to allow access by a Type 3 Wildland Fire Engine. All road maintenance will occur within the existing road prism and there will be no creation of new roads. Erosion control BMP’s will be implemented as needed for any ground disturbance in the vicinity that has the potential to transport sediment. Where mineral soil has been exposed on approaches to watercourse crossings of Class I, II, or III, the disturbed area will be stabilized to prevent the discharge of soil. Water breaks will be installed to prevent runoff from roads or fire lines reaching a watercourse where deemed necessary. Vegetation will be burned in a mosaic pattern which will prevent riling and channeling and those unburned areas between the project and creeks will buffer any minor runoff. Treatment areas will be monitored for erosion control and mitigations prior to the rainy season. The broadcast burn prescription will be designed to minimize soil burn severity by excluding burning in conditions that would result in a high severity fire. Project activities will not violate any water quality standards, deplete groundwater, or substantially alter the existing drainage pattern. Impacts to hydrology and water quality are expected to be less than significant. A notification letter was emailed to Jim Burke (Senior Engineering Geologist) of the North Coast Regional Water Quality Control Board on February 19, 2024, with project description, protection measures, and project map. He was invited to share information or any concerns the Board might have regarding potential impacts to water quality. A response was received from Youzhu Wang (ES Forestry and Wildfire Resiliency Unit Division of Water Quality) on March 26, 2024, with a letter highlighting a few standard project requirements for the project. B. PROJECT TOPOGRAPHY: The project area lies primarily within the Gibson Creek planning watershed, with portions in the Orrs Creek, Upper Robinson Creek, and Lower Robinson Creek planning watersheds, all of which drain into the Russian River. This area is within the Mendocino County interior region of hot, dry summers and cool, wet winters. The mean annual precipitation is 39 inches and primarily occurs from October to May. The terrain generally consists of moderately steep slopes (50-70%), along with moderately sloping ridgelines and benches (20-50%). Elevations range from 587 feet up to 2,766 feet. Trending ridgeline aspects generally face south or north on either side of east/west running drainages, while some smaller western and eastern -facing slopes are also distributed across most of the units. C. SOILS DESCRIPTION AND SENSITIVITY TO PROJECT ACTIVITIES: Refer to “Geology and Soils” discussion in Section 1.3 A above. D. VEGETATION COMMUNITY AND DOMINANT SPECIES: The project area is located within the Northern California Coast (263A) and Northern California Coast Ranges Ecological Section (M261B), and ranges in elevation from 587 feet up to 2,766 Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU feet. Vegetation within the project areas consists primarily of dense chaparral, predominantly comprised of chamise, mixed hardwood -conifer woodlands, evergreen shrubs and native and non-native grasses and forbs. There are a few areas of oak woodland present within montane hardwood on the outskirts of the project area . The vegetation types targeted for treatment in this plan, as classified in the CWHR habitat classification scheme, include annual grassland, mixed chaparral, chamise-redshank chaparral, and understory vegetation in montane hardwood and montane hardwood-conifer. Hardwood-pine overstory is not targeted for burning. Many of the dominant plant species in these habitat types have evolved adaptations for surviving and thriving after fire. Treatment units contain a mixture of grassland and chaparral, integrated with patches of woodland vegetation types. Prescribed burning will enhance native plant species that have evolved with fire, while simultaneously reducing non -native invasive plants where possible. The frequency and intensity of burning is designed to avoid type -conversion of native vegetation. Prescribed burns are generally beneficial to wildlife by stimulating herbaceous plant diversity. They are also used to stimulate growth of forbs, legumes and native grasses that are beneficial as food and cover for a variety of wildlife species. For a chaparral ecosystem, the deep roots of associated species help to stabilize slopes and allow them to thrive. Chaparral plant communities depend upon fire as an integral part of their life cycle and periodic burning is essential in order for these communities to rejuvenate, either from burl forming or seed sprouting species. As unburned plants grow older, the amount of dead material increases. The elimination of unnatural accumulations of dead and down vegetative debris will reduce the fire intensity of a wildfire occurring during peak burning conditions during the summer or fall months. Where chaparral plants are uniformly old, and cover a broad area, fires tend to be large and devastating. The use of low -intensity prescribed fire will improve nutrient cycling and serve to re-establish natural vegetative seral stages and fuel loadings. Certain species of wildlife will benefit from younger stages while others, dependent on mature chaparral or dense woodland understory, could be adversely affected by such changes. However, the effect is not substantial given the adaptability of many species and the fact that the vegetation burns at various intensities depending upon aspect, slope percent, slope position, and ignition sequence/duration. This results in a mosaic effect, of burned and unburned areas, with the overall impact generating habitat diversity, both in structure and plant species, supporting numerous wildlife species. Regeneration of chaparral species occurs through both the sprouting and reseeding process. Fire removes shade that would otherwise hinder seedling success as well as allelopathic germination inhibitors found in both the decaying organic material and the soil. Germination may also be induced by heat shock or scarification of hard seed coats, nitrates released during combustion, smoke, or a combination of these factors. Research and experience have shown that fire can be used as a major management practice for native and introduced grasslands, hay meadows, and establishing and managing new native grass stands. Fire improves nutrients availability in the ecosystem by releasing nutrients tied up in woody material, stimulates tillering, controls many woody and herbaceous plants, improve Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU grazing distribution, and reduces wildfire hazards. Many undesirable grass, broadleaf, and woody species can invade and reduce forage production and availability of native grasslands. Prescribed burning can be used to reduce the invasion of these plants and maintain healthy grasslands. E. WILDLIFE/FISHERIES HABITAT AND SENSITIVITY TO PROJECT ACTIVITIES: Refer to “Biological Resources” discussion in Section 1.3 A above. F. CULTURAL RESOURCES AND SENSITIVITY TO PROJECT ACTIVITIES: Refer to “Cultural Resources” discussion in Section 1.3 A above. G. SMOKE AND COMMUNITY SENSITIVITY TO PROJECT: The Ukiah West Hills project is situated atop the hills directly west of Ukiah, CA and the surrounding parcel zoning ranges from Rural Residential to the City and the County. The West Hills area remains predominantly undeveloped, excluding existing firebreaks, private access roads, and an operational communication tower with its associated infrastructure. The area serves various purposes, including rural and remote residences, agricultural activities, wildlife management, and unsanctioned recreational use. The City of Ukiah borders a portion of the project area on the east. Most of the developed parcels are located east of the project area. The east portion of the West Hills is bounded by the highly populated City of Ukiah. The ideal wind direction for prescribed burns will be from the southeast-east-northeast, driving smoke in a west-northwest direction, away from the closest most populated area. The burn prescription has been designed to mitigate the effects smoke on adjacent properties. Also reference Smoke Management Plan (below). H. GREENHOUSE GAS: Greenhouse Gas (GHG) Emissions Calculations The potential for generation of GHG emissions was evaluated for this project. The First Order Fire Effects Model (FOFEM) was used to determine the amount and type of emissions likely to occur through project implementation. Emission calculations are based on factors including fuel models, fuel conditions, and expected fuel consumption in tons per acre. Calculations were made for a maximum burn acreage of each Fuel Model below. Refer to the attached FOFEM calculations for Fuel Models 4, and 8 and 9. FOFEM CO2 Emissions: Fuel Model FOFEM CO2 Emissions lbs/ac Fuel Load Tons/Ac Acres Total CO2 Emissions (MT) FM 1 n/a n/a 1 n/a FM 4 38,413 17.14 278 4,765 FM 8 66,932 29.88 48 1,464 Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU FM 9 29,621 13.22 220 2,909 Total CO2 emissions: 9,138 First Order Fire Effects Model (FOFEM) estimates that the planned prescribed burning will emit an annual average of 9,138 metric tons of carbon dioxide for 545 acres (burn units) and 27 tons of CO2 from motorized exhaust as a result of this project. Carbon dioxide that is released into the atmosphere by this project will be sequestered by growth of new vegetation following the prescribed burn. One objective of this project is to reduce the overall fire hazard in the area which will lessen the chances of a large damaging wildfire. Large wildfires can cause significant impacts to the environment including the emission of huge quantities of “greenhouse” gasses. Reducing the wildfire threat through focused fuel treatments, including prescribed burns, will lead to the long-term reduction in the number and size of large fires. Reducing this threat will benefit the environment in a number of ways including the reduction of greenhouse gas emissions. One of the VTP objectives is to inhibit/prevent the spread of a wildfire moving through these watersheds under severe fire weather conditions. The weather and fuel moisture parameters prescribed in this burn plan will result in a rapid moderate intensity burn in grass with minor effects on trees. In chamise and mixed chaparral fuel types where dead woody material is present fire will move through at a higher intensity but overall, it will generally be a moderate intensity burn through all units. Fuel type conversion will not occur. A mosaic burn pattern in the chaparral fuel type is planned with a fuel consumpti on rate of approximately 60-70%. FM 4 will have a higher rate of consumption while FM 8 and 9 will have lower rates of consumption. This is lower than would occur under a high intensity wildfire. The lower the fire intensity, the lower the CO2 emissions. Fuel reduction projects that do not change the vegetation type are carbon neutral over time. The planned mosaic burn pattern will lower the overall fuel consumption rate. The time needed to sequester the carbon released by this prescribed fire project will be determined by the subsequent regeneration of the vegetation.

SCHEDULE: Burn Days: Monday through Friday, and weekends if conditions are favorable Burn Months: August 15 through March 15 for mosaic ecological burning March 15 through June 30 for wildfire hazard reduction June through August for grassland burns. Burning will be conducted when fuels are within prescription and the burning will achieve the desired treatment objectives for both wildlife fuel mosaic and wildfire hazard reduction of fuels. Wildlife fuel mosaic burning consists of perimeter and interior ignition at a level sufficient to obtain a target fuels consumption of approximately 60 -70%. Fire will be allowed to back into burn units until spread is no longer possible due to fuel and ground moisture conditions. B. FUEL DESCRIPTION: Vegetation communities across the entirety of the West Hills are characterized by dense chaparral, predominantly comprised of chamise, and mixed hardwood -conifer woodlands. The vegetation within the cleared control lines primarily consists of native and non -native grasses and forbs, interspersed with patches of mixed hardwood -conifer trees and evergreen shrubs. Vegetation types in the vicinity of the project area encompass grasslands, chamise chaparral, manzanita chaparral, mixed hardwood forest, and Douglas -fir – hardwood forest. Chaparral coverage varies from nearly continuous to sparse, with grassy openings and areas featuring a mixture of hardwood tree species and grasses. The chamise component ranges from pure stands to a 50/50 mix with ceanothus, manzanita, and other chaparral species along with minor amounts of herbaceous vegetation. The application of prescribed fire within this project will be confined to grassland, chamise, and mixed chaparral fuel types. Estimated fuel type composition of the burn units is 5% grass (mixed herbaceous), 55% chamise/mixed chaparral, and 40% conifer/hardwood forest (Doug-fir, Pacific madrone, tanoak). 1) FUEL TYPE AND CHARACTERISTICS: a. FUEL MODEL(s): model number based on Hal Anderson’s Aids to Determining Fuel Models, General Technical Report INT-122. FM 1 - This fuel type consists of 1-hour fuels and is characteristic of the grassland in scattered openings found through the project area. This area includes oak woodland. Fire is expected to burn through cured surface fuels rapidly with little residual burning and minimal effect on oaks. There are areas of grassland intermixed throughout the project area. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU FM 4 - This is the primary chaparral model found scattered throughout the project area. Fire spreads with high intensity and rapid spread through the foliage and the live/dead fine woody material in the crowns of shrubs. The primary species is chamise, with the balance consisting of mixed chaparral stands of ceanothus and manzanita species, toyon, and poison oak. Dead woody material in parts of the stand will significantly contribute to fire intensity. Most of the proposed project area and burn units are composed of mixed chaparral. Chamise chaparral is commonly found on the south - facing, xeric slopes within the project area. FM 8 - This is a timber litter model. Dead foliage litter is primarily tightly compacted hardwood or conifer litter. As fire extends into these areas from chamise/chaparral stands, slow-burning ground fires with low flame heights should prevail, although fire may encounter an occasional "jackpot" or heavy fuel concentration that can flare up. Some species in this model have ladder fuels associated with them but fire is not expected into the canopy under the target burn prescription. The main conifers present in the project area are Doug-fir, pine, and redwood. Areas of mixed hardwoods and Douglas-fir forests are present on north-facing slopes and along drainages in the project area; hardwoods typically include tanoak and Pacific madrone. FM 9 - This is a timber model consisting of dense stands of conifers and mostly hardwoods located on north-facing slopes and within ravines. The primary fuel is dead foliage consisting of tightly compacted hardwood or conifer litter. Under the weather and fuel conditions prescribed for this project, it is expected that surface fire will be minimal. b. VEGETATION 1” to 24" TALL: This vegetation includes annual grasses, which are expected to be fully cured when the burn is conducted. Perennial grasses and herbaceous fuels are present in various burn units. c. VEGETATION 24” PLUS: Vegetation includes FM 4 chamise, ceanothus spp., manzanita, and other chaparral fuels. Chamise has a live component ranging from 60-80%. At the time of the burn, the chamise will have a live fuel moisture between 60-80%. Vegetation in the project area greater than 6-ft tall includes conifer and hardwood stands. d. FUEL ARRANGEMENT : The fuel component ranges from annual and perennial grassland, oak woodland, chaparral, pine, and some mixed conifer. FM 1 fuels are arranged vertically. FMs 4, and 8 are primarily arranged vertically with a horizontal component including a duff layer. FM 4 consists of chamise and mixed chaparral. Closed canopy hardwood/conifer stands and /or stands interspersed with chaparral species characterize FM 8 and closed canopy montane hardwood characterizes FM9. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU e. FUEL CONTINUITY : FM 1: Continuous FM 4: Nearly continuous. Canopy cover ranges from 80-90%. FM 8: Nearly continuous. Canopy cover ranges from 50-80%. FM 9: Continuous. Canopy cover 95% or higher. Fuel continuity is similar for fuel models both within and outside of the project area. Fire will be used in a manner (within a specified range of environmental conditions) to target the primary fuel type in each unit. In many instances, units are a heterogenous mixture of grassland and chaparral, but may also contain overstory tree species not part of the burn prescription. f. SURFACE FUEL DEPTH : Annual and perennial grasses: 1-2 ft. Chamise and mixed chaparral: 3-6 ft. Conifer or mixed hardwood stands: 4”-3 ft. g. DUFF DEPTH: The FM 4 understory fuels consist primarily of leaf litter and duff, ranging from 1 -in. to 4- in. depth. Where the FM 8 and 9 hardwood/conifer overstory is dense, there is a light- to-moderate component of 100 and 1000-hour fuels. 2) FUEL LOADING: FM 1: Total fuel load is generally less than 1 ton/acre. Fuel is expected to be cured at time of ignition. FM 4: Total fuel load ranges from 8-12 tons/acre, dead fuel load estimated at approximately 4-5 tons/acre. FM 8: Total fuel load ranges from 2-6 tons/acre, includes both live and dead woody material. FM 9: Total fuel load ranges from 3-4 tons/acre, dead fuel load estimated at approximately 2-3 tons/acre. 3) FUEL CONSUMPTION PLANNED: FM 1: 70-90% FM 4: 60-70% FM 8: 40-60% FM 9: 20-40% 4) FUEL TREATMENT PLANNED: Fire lines may be constructed as necessary to secure unit perimeters by bulldozers or hand crews. A masticator may be used from the road to pretreat control lines. 5) NARRATIVE: Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU Target fuel for burning range from grass to chamise and mixed chaparral to timber understory. a. FIRING/IGNITION PROCEDURES: Firing will typically begin uphill and upwind and proceed down slope and into the wind, until sufficient black line is created to assist in containing the fire at the prescribed intensity. Ignition devices include, but are not limited to: drip-torch, terra-torch, PSDs, and helitorch. The IC, Operations Chief, and/or Burn Boss will determine the timing and location of the different firing tools and methods. b. PROVISIONS FOR TEST FIRE & RECORDING RESULTS: The test burn will be conducted on the day of the burn in a representative location within the project area. The test burn will be adequately sized to determine whether the project burn is feasible under ambient temperature, humidity, wind conditions, if smoke dispersal and direction are acceptable and within planned constraints, if fuel consumption is adequate to meet objectives, and if fire behavior will produce results within acceptable parameters. These results will be used to proceed with the Go/No Go decision. c. HOLDING PROCEDURES: The primary objective for holding resources is to keep the prescribed fire within established control lines. The Holding Group Supervisor will provide direction to all holding resources assigned. Efforts will concentrate on mitigating possible threats to burn plan objectives, protection of sensitive features and to reduce any potential risk identified by the Holding Group Supervisor, Division Group Supervisors, Operation Section Chief, or the Incident Commander. d. OTHER PROJECT MANAGEMENT CONCERNS: Communications Needs All ignition personnel, holding personnel and assigned overhead will be equipped with HT radios. All personnel will be briefed on communication procedures and frequencies assigned to the project. Frequencies assigned to the project are defined in the Communications Plan (ICS 205) found in the Incident Action Plan (IAP). Medical Facility Medical facilities are outlined in the Medical Plan (ICS 206) found in the IAP. Safety and Health/Job Hazard Analysis SAFETY IS THE NUMBER ONE PRIORITY. All participants will utilize appropriate personal protective equipment (PPE). Refer to the IAP Safety Message and Job Hazard Analysis for additional safety concerns. All participants will receive a safety tailgate briefing (IIPP6) by their assigned supervisor. Direct fire line supervision will be utilized by Division Group Supervisors if necessary. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU Helicopter Operations A CAL FIRE helicopter may be utilized for firing operations. In the event of an escape the helicopter will deploy the water dropping bucket for suppression activities. All appropriate aircraft safety policies will be reviewed, and personnel will be briefed prior to operations. Escaped Fire Procedures The Incident Commander (IC) is responsible for declaring an escaped fire. In the event of an escaped fire, the IC will make required notifications and request additional resources as needed. Post Burn Summary and Documentation Upon completion of the burn, a post burn evaluation will be completed using a Prescribed Burn Completion Report. The evaluation will be used to determine if the burn plan objectives were met. C. WEATHER AND FUEL MOISTURE: General information: The VTP burn prescription is a combination of desired weather and fuel conditions needed to accomplish various burn objectives, such as to reduce h igh fire hazard fuels by 50%, to improve wildlife habitat forage, and to maintain/increase the balance of native plant species. The burn objectives will dictate how hot or cool the fire should burn, when and where to burn, and what equipment to employ for best results. The results can be obtained from nomograms but preferably are obtained from a recent BehavePlus (a computer model of fire behavior outputs that require weather and fuel moisture numbers for input , current version 6 Beta was released on February 7, 2018 ). The opportunity to burn is referred to as a "burn window ” and is dependent on the range of weather and fuel moisture tolerances allowed in the prescription. The window should be wide enough to achieve objectives without jeopardizing personnel safety. A narrow burn window limits the statistical probability that the conditions will be met and assumes that specified personnel and equipment are readily available . 1) WEATHER DATA COLLECTION: a. LOCATION(S) /METHOD(S) OF DATA COLLECTION: Information regarding local weather and wind speeds may be obtained from a portable RAWS station placed at the project site prior to and during project burn implementation. Additional information regarding weather and wind speeds will be obtained from the Ukiah Municipal Airport NWS/FAA station: ID: KUKI Latitude: 39.12783° Longitude: -123.20011° Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU Elevation: 597-ft Location: Ukiah Municipal Airport MNET: NWS/FAA IMS ID: Accessible at: https://mesowest.utah.edu/cgi-bin/droman/meso_base_dyn.cgi?stn=KUKI Personnel will be assigned to monitor the site before ignition and hourly until the fire is declared out by the incident commander. Personal data collection will utilize Kestrels and/or sling psychrometers w/NOAA National Weather Service Relative Humidity/Dew Point Tables to obtain dry/wet bulb temperatures & relative humidity. Wind speeds will be obtained using Kestrels. Other weather-related sites such as www.nws.noaa.gov, and http://www.arb.ca.gov . Local news media weather forecasts may be used as needed. b. DATA TO BE COLLECTED: Location Elevation Time Wind speed/direction Temperature Wet bulb RH Dew Point Sky/weather c. SAMPLING PERIOD: The RAWS platform provides for hourly sampling. Data can be retrieved online or via radio as necessary. A record of the Ukiah Municipal Airport NWS/FAA will be obtained for 1 week prior to the burn, with this record included in post -burn documentation. Data collection will begin when personnel arrive on site on the day of the burn and will continue until mop-up operations are complete. Weather will be taken hourly or anytime a significant atmospheric change is observed. d. FORECASTS: Spot weather forecasts will be obtained prior to and on the day of the burn. Primary forecast elements will be sky/weather summary, temperature, humidity, eye level winds, 20-foot winds, chance of wetting rain, marine layer and lightning activity level. Weather discussions will also be evaluated to determine the possibility of approaching frontal systems. General weather forecasts will be obtained locally as available. e.

Additional information pertaining to estimated smoke mixing heights and upper level smoke transport winds, as well as Spot Weather Forecasts are available from the NWS Predictive Services Unit in Redding at: http://gacc.nifc.gov/oncc/predictive/weather/ Prescribed burn planning, smoke management, and reporting is coordinated with the MCAQMD through the Prescribed Fire Information Reporting System (PFIRS), managed by the California Air Resources Board. Public dashboard: https://ssl.arb.ca.gov/pfirs/ f. SPECIFICATIONS, WARNINGS: No adverse changes in weather patterns predicted over the project area during or immediately following burning operations. The burn will not be implemented should any adverse weather event be predicted that will exceed prescription parameters or threaten burn plan objectives. Approval and shutdown of burning operations are subject to determination by the Mendocino County Air Quality Management District (AQMD). Consultation may also occur with the Lake County Air Quality Management District (LCAQMD) and the Glenn County Air Pollution Control District (GCAPCD). g. PROBABILITY OF ADVERSE WEATHER: Based upon pre-burn monitoring of meteorological conditions and spot forecasts to be received from the NWS, as well as discussions with the M CAQMD, it is estimated that there is less than a 10% chance that unpredicted adverse conditions will occur on site during the burn and within 24-hours following completion of the burn. h.

AFFECTED AREAS AND CONDITIONS: 1) AIR POLLUTION CONTROL DISTRICT (AIR QUALITY MGMT DISTRICT): Mendocino County Air Quality Management District 306 East Gobbi Street Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU Ukiah, California 95482 Phone: 707-463-4354 Email: mcaqmd@mendocinocounty.org The project area is located within central Mendocino County and not adjacent to any other air district. 2) AIR BASIN: North Coast 3) SMOKE SENSITIVE AREAS: The community/city of Ukiah, and associated rural development area, and Highway 101 are the most smoke sensitive areas. Other communities include Redwood Valley, Hopland and Navarro which are not expected to be impacted by smoke. Distances: Ukiah: Directly east bordering the edge of the community Redwood Valley: 10.7 miles northeast Boonville: 21 miles southwest Hopland: 15 miles south 4) AIR QUALITY CONDITIONS: Burn only on a permissive burn day unless otherwise approved by MCAQMD. Visibility impacts are unlikely due to the low population density surrounding the project area. Smoke may impact a small number of residents within the vicinity, but those impacts are expected to be transitory and insignificant. Any unanticipated smoke impacts would follow measures outlined in the smoke management plan. B. SMOKE DISPERSAL PLAN: 1) WIND DIRECTION: NE, E, SE would be preferable, any direction would be acceptable given enough venting and mixing. 2) VENTING ELEVATION: Minimum of 500 feet. 3) SMOKE DISPERSAL AREA(S): None Smoke Travel Projections - Although planned downwind areas are largely rural, there are smoke sensitive areas such as the communities listed above. Smoke travel during project implementation will depend upon prevailing surface and gradient winds. The target wind projection of NE/E/SE will result in a smoke projection of SW/W/NW. This information is based on prevailing wind data collected from the Ukiah Municipal Airport NWS/FAA station. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU 4) VISIBILITY FACTORS: Project Site: None Smoke Dispersal Area: None 5) NARRATIVE: All burning shall be conducted in accordance with direction from the MCAQMD. It is not expected that smoke from this burn will affect air quality outside of the county. Smoke receptors for the project are the nearby communities as noted above, city of Ukiah, as well as vehicle traffic on Highway 101 and residences located along the Highway 101 corridor, and along nearby rural roads. Burn conditions specified in the prescription will mitigate adverse smoke impacts. A n easterly wind pattern will move smoke away from most populated areas. Smoke columns will be visibly monitored for direction and lift in order to evaluate smoke dispersal/transport predictions. Personnel will be assigned to observe smoke dispersal as necessary. The burn will be curtailed if the planned convective lift and/or planned dispersal cannot be achieved. Smoke dispersal conditions will be evaluated in the morning, at the test burn, and continually monitored throughout the duration of the project. On site monitoring will include weather, smoke and fire behavior observations. Additional Information will be collected from the CAL FIRE Portable RAWS located at the project area. Estimated mixing heights and upper level transport winds will be obtained from the Redding Interagency Fire/Forecast Warning Unit internet site at: www.fs.fed.us/r5/fire/north/fwx/smok.txt or at the National Weather Service-Eureka spot forecast internet site at: http://www.wrh.noaa.gov/eka/. In an effort to minimize daily and cumulative air quality impact to the regional area, the project will be scheduled in coordination with the MCAQMD and any other local ag ency prescribed fire projects. 1.7 Public Information Plan CAL FIRE Mendocino Unit will issue a county-wide press release 24-hours prior to the burn. This press release will include contact information for a public information officer who can answer questions regarding burn activities. CAL FIRE will also notify surrounding residents one to three days prior to the planned burn date. On the day of the burn, the following agencies will be notified : MCAQMD: (707) 463-4354 CAL FIRE Howard Forest Command Center: (707) 459-7403 Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU 1.8 Project Implementation Task Schedule Tasks Responsible Party Time of Completion Any required pre-operative surveys for specific areas Environmental Coordinator Prior to operations (new control lines and ignition) Burn unit layout and flagging of protected areas Environmental Coordinator Prior to operations (new control lines and ignition) Construction of fuel breaks/control lines Landowner/CAL FIRE Prior to ignition Road grading/repair for access Landowner/CAL FIRE Prior to ignition MCAQMD Smoke Management Plan IC Prior ignition Public Information Plan IC See 1.7 Public Information Plan MCAQMD Burn Authorization Plan IC Day prior to ignition Prepare Incident Action Plan (IAP) IC Day prior to ignition Prepare Go/No Go Checklist IC Day of ignition Obtain burn approval from CAL FIRE MEU ECC, Duty Chief, Unit Chief, and Region Chief IC Day of ignition Conduct test fire IC and Ground Resources Day of ignition Prescribed fire ignition IC and Ground Resources Day of ignition Extinguish and Mop-up IC and Ground Resources IC discretion Post-burn evaluation and response of vegetation, assessment of protected areas Environmental Coordinator/Archaeologist/VTP Forester At least several months after the burn Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Ukiah West Hills VTP Section 1 – Project Plan RX NORTH-107 MEU 1.9 List of Attachments Section 2: PROJECT COST SUMMARY Apportionment of Benefits CALFIRE Resources Cost Analysis Worksheet Section 3: ENVIRONMENTAL CHECKLIST Section 4: INCIDENT ACTION PLAN Plan attached Plan to be submitted with first activity report Smoke Management Plan OTHER ATTACHMENTS RM-75 Agreements for Prescribed Burning Project Maps BEHAVE outputs FOFEM outputs Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 UKIAH WESTERN HILLS VEGETAT CALVTP PROJECT SPECIFIC ANALYSIS AND ADDENDUM FOR THE ION TREATMENT PROJECT Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 Exhibit D (Beneficial Fire Standard Agreement - RM 75) TABLE OF CONTENTS LIST OF ABBREVIATIONS ..............................................................................................................................

Several factors have contributed to the current conditions, including but not limited to substantial development in the Wildland Urban Interface (WUI), the impact of climate change, years of severe drought, and the overall suppression of naturally occurring fires. The goal, with the help of this document, is to treat lands around the community of Ukiah to help build resilience against wildland fire, while also improving the overall quality of the local ecosystem. The Final Program Environmental Impact Report (PEIR) of the California Vegetation Treatment Program (CalVTP; State Clearinghouse #2019012052) evaluated potential environmental consequences associated with the implementation of qualifying vegetation treatments aimed at reducing the risks of wildfire throughout the State Responsibility Areas (SRAs) in California. The PEIR was designed for use by many State, special district, regional, and local agencies to expedite the approval process for vegetation treatment projects falling within the same scope of the PEIR. When needed, the PEIR is supplemented with minor technical details concerning a proposed project, presented in the form of an addendum, as is the case with this document. This document addresses technical details for the treatments surrounding the City of Ukiah (referred to as “the City”). To assist with this effort, the California Board of Forestry and Fire Protection (referred to as “the Board”) supports the preparation of Project-Specific Analysis (PSA) documents. These documents are intended to establish a repository of exemplary projects that can assist both State and local agencies in creating their PSAs under the CalVTP PEIR. Furthermore, they facilitate compliance with the California Environmental Quality Act (CEQA) for the proposed projects. The Board selected the Mendocino County Fire Safe Council (MCFSC) proposed vegetation treatment project under the California Climate Investments Fire Prevention Grants Program, and this PSA provides CEQA-compliance for the approval and implementation under the CalVTP PEIR, thus streamlining the approval process for the Ukiah West Hills VTP. 1.1.1 Proposed Project In 2019, Governor Newsom included the Ukiah Emergency Fuels Reduction Project as one of 35 priority projects to implement immediately to reduce public safety risks for the most wildfire-vulnerable communities. Under a State of Emergency, the requirements of CEQA were suspended and environmental protections are built into the project design. CAL FIRE currently proposes to implement vegetation treatments including maintenance and retreatment on up to 998 acres of land on the western side of Ukiah Valley in Mendocino County (Figure 1.1-1). This treatment would ultimately protect approximately 5,961 acres within the Project Influence Zone, also considered the total Project Area. This includes property owned by the City of Ukiah, Mendocino County (referred to as “the County”), and privately owned lands within the Russian River watershed, specifically on slopes west of the City. The project area is utilized for rural residence, agriculture, recreation, and wildlife management . This project is the result of a Wildfire Prevention Grant that was awarded to the Mendocino County Fire Safe Council (MCFSC), CAL FIRE Grant Project 21-CNR-MEU-024. The proposed treatment methods (commonly known as “fuel breaks”) and the associated activities (involving prescribed burning, manual and mechanical treatments, as well as herbicide application) are consistent with those evaluated in the CalVTP PEIR. Ongoing maintenance of initial treatments (referred to as “retreatment/treatment maintenance” or “maintenance” in this PSA) would employ the same types of vegetation treatment and activities used in the original treatment. The primary goal of the prescribed burn is to reduce the overall fuel load, thereby diminishing the likelihood of future catastrophic wildfires within the Project Impact Zone (PIZ). This will be accomplished by reintroducing fire as a natural component of the ecosystem. A secondary goal involves enhancing wildlife habitat by encouraging new growth from sprouting species to increase forage production. Within burn units, pockets of unburned fuel will undoubtedly remain to provide shelter for small mammals. Portions of the project site have remained fire-free for over two decades, allowing fuel accumulation to reach maximum levels. Consequently, wildlife movement within the area has been significantly reduced, and the flow of water from creeks and springs has been curtailed. All native vegetative and wildlife species present within the project area are fire -adapted. The reintroduction of fire into this ecosystem is part of the natural process. The perimeters and interiors of burn units will be ignited using a combination of methods: heli-torch (aerial), terra-torch (mobile), and drip-torch (on-foot). Chemical management of undesirable species would not accomplish any of the objectives listed above, would not be economically feasible, and may also have negative environmental impacts. Prior to burning, mechanical treatment of fuels (such as crushing, bunching, and the use of a ball and chain) may occur in select portions of the burn units. The prescribed burning conducted as part of this project will be carefully planned to achieve specific goals and will be conducted under specific climatic conditions to ensure control and minimize impacts on air quality and the environment. These Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 2 conditions will mimic air, soil, and vegetation moisture, and other parameters present during natural wildfires, thereby maximizing the positive impacts of fire on vegetation. 1.1.2 Lead Agency For the purposes of the CalVTP PEIR and this PSA, a project proponent is defined as a public agency that provides funding for vegetation treatment, possesses land ownership, land management, or other regulatory responsibility within the treatable landscape, and aims to finance, authorize, or execute vegetation treatments consistent with the CalVTP. This document is being prepared for CAL FIRE, the County, and the City to ensure compliance with CEQA for the implementation of vegetation treatments that require discretionary action by a State or local agency. The CEQA lead agency is CAL FIRE. CAL FIRE will establish a partnership with MCFSC, the County, and the City to carry out the proposed treatments. The partnership may involve providing resources to the MCFSC, the County, and the City including equipment, staffing, and technical input. In this PSA, the CAL FIRE is referred to as the “implementing entity,” underscoring its role as the primary executor of the treatments. The Ukiah Valley Fire Authority’s fuels crew will conduct operations on City-owned lands. 1.1.3 Purpose of This Project-Specific Analysis/Addendum This document functions as the PSA, aimed at evaluating whether the proposed treatments fall within the scope of the CalVTP PEIR. As stated above, the types of treatments and their associated activities are consistent with the CalVTP. One of the additional criteria used to determine whether a treatment project aligns with the CalVTP PEIR pertains to its inclusion within the CalVTP treatable landscape - defined as the geographical extent covered by the PEIR analysis. If a proposed vegetation treatment project undergoes evaluation for environmental effects within the PEIR, it could receive approval based on a determination that the project falls within the PEIR’s scope for CEQA compliance, consistent with CEQA Guidelines Section 15168(c)(2). If a proposed project includes a substantial portion of the State Responsibility Area (SRA) treatable landscape while also extending partially beyond the SRA, it may still rely on the environmental analysis within the PEIR, if the environmental conditions of the outside landscape and the foreseeable environmental impacts of proposed treatments are consistent with the descriptions in the PEIR, as discussed below. The proposed project is in the SRA, but not entirely within the CalVTP treatable landscape (Figure 1.1-2). There are 78 acres within the PIZ that are identified as being within the Federal Responsibility Area (FRA), but there are no treatments planned for these acres. Additionally, there are 624 acres that fall within the Local Responsibility Area (LRA). The portions of the project treatment areas that extend beyond the treatable landscape (SRA), as outlined in the CalVTP PEIR. In total, these areas encompass approximately 73 acres within the LRA. Nonetheless, they are dispersed across small sections of treatment areas (refer to Chapter 2, “Treatment Description”). The scattered arrangement of acres beyond the CalVTP treatable landscape is attributed to the method by which the CalVTP treatable landscape was digitally developed, as well as the resulting mapping resolution. Using desktop applications to apply buffers around geographic and topographic features and demarcate jurisdictional boundaries (i.e., SRA and LRA), the method resulted in some treatable landscape areas appearing disjoined and scattered on the maps, while others existed as inholdings within the SRA. If the areas of the proposed project located outside of the CalVTP treatable landscape exhibit essentially identical or substantially similar landscape conditions as the adjacent areas within the treatable landscape, the environmental information in the PEIR would be relevant and applicable . An addendum to an Environmental Impact Report (EIR) is warranted when a previously certified EIR has been prepared and proposed changes or revisions to the project, or shifts in project circumstances, do not introduce new or considerably more significant adverse environmental impacts. This is consistent with CEQA Section 21166 and CEQA Guidelines Sections 15162, 15163, 15164, and 15168. In this case, while there are no altered circumstances, the proposed revision or change in the project, compared to the PEIR, involves incorporating some small areas outside of the CalVTP treatable landscape. The PSA checklist (refer to Section 4, “Project-Specific Analysis/Addendum”) includes the criteria supporting an Addendum to the CalVTP PEIR for the inclusion of treatment areas outside the CalVTP treatable landscape. The checklist evaluates each resource in terms of whether the subsequent treatment project, including the “changed condition” of additional geographic area, would result in significant impacts that would be substantially more severe than those covered in the PEIR or introduce new impacts not covered in the PEIR. This document serves as both the PSA and an addendum to the CalVTP PEIR for review and analysis under CEQA for the proposed Ukiah West Hills vegetation treatments within and outside the CalVTP treatable landscape. The project-specific mitigation monitoring and reporting program (MMRP), which outlines the CalVTP standard project requirements (SPRs) and the mitigation measures applicable to the proposed project, is presented in Attachment A. The SPRs identified in the MMRP have been incorporated into the proposed vegetation treatments as a standard part of treatment design and implementation. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 3 2 TREATMENT DESCRIPTION The main proposed treatment type is the creation of fuel breaks. Proposed treatment activities include manual and mechanized treatments, prescribed burning, and herbicide application. The locations for these treatment types are shown in Figures 2.0-1 and 2-2. Tables 2-1 and 2-2 provide treatment summaries. The proposed vegetation treatments would occur in one main area, referred to as the West Hills area. This area consists of various private and public (City and County) lands situated on the western side of the Ukiah Valley. The total potential treatment footprint of this project is 5,961 acres in size. 2.1 PROJECT SITE DESCRIPTION The aim of this project is to reduce wildfire risk in strategic areas around and to the west of the City of Ukiah, which is Mendocino County’s capital and most populous city by far. These are as are particularly important for community protection because prevailing winds come from the west and the Ukiah Valley is bounded by substantial fuel-rich wildlands that pose a substantial wildfire threat. With CEQA in place, CAL FIRE’s MEU will implement fuel-reduction work and prescribed burning to establish and maintain these critical fuel breaks surrounding the Ukiah Valley. The treatment within the West Hills area will help protect approximately 13,000 threatened homes, essential services, and critical communication infrastructure within the City and unincorporated neighborhoods in the Ukiah Valley, totaling approximately 20,822 acres. Ukiah is the Mendocino County seat and center for government services. It contains the County’s largest medical center, as well as schools, water treatment plant, extensive retail development, and other infrastructure. Ukiah also has a high density of homes and structures adjacent to steep, undeveloped wildlands identified as Very High Fire Hazard Zones. The West Hills of Ukiah also contain hundreds of homes scattered throughout heavy fuel loads in WUI areas contiguous with urban neighborhoods, increasing the risk of wildfire spreading to homes and infrastructure throughout the Ukiah Valley. The Ukiah Valley is surrounded by mainly steep, undeveloped, mountainous terrain with high fuel loads. The need for this fuel reduction work is based on the high likelihood of wildland fire moving west towards the Ukiah Valley (due to prevailing westerly winds throughout the region). Implementation will impede the spread of wildland fires at strategic locations above the Ukiah Valley and continue improved defensible space and evacuation routes to homes in the WUI. The PIZ lies primarily within the Gibson Creek planning watershed, with portions in the Orrs Creek, Upper Robinson Creek, and Lower Robinson Creek planning watersheds, all of which drain into the Russian River. The Russian River watershed primarily covers eastern Mendocino County, extending south through Sonoma County, and ultimately draining into the Pacific Ocean near Jenner, CA. Encompassing an area of approximately 1,485 square miles (950,400 acres), the Russian River watershed area is used for activities like grazing, agriculture, timber harvesting, recreation, urban development, and residences. Located within a region of Mediterranean climate, the Russian River watershed typically experiences hot, dry summers and cool, wet winters, with an average annual precipitation of 39 inches, primarily occurring from October to May. The Ukiah West Hills VTP area generally consists of moderately steep slopes (50-70%), along with moderately sloping ridgelines and benches (20-50%). Elevations range from 587 feet up to 2,766 feet. Trending ridgeline aspects generally face south or north on either side of east/west running drainages, while some smaller western and eastern-facing slopes are also distributed across most of the units. All fuel-reduction activities proposed under this project directly target residences within the WUI, situated in high-risk areas prone to wildfire, and are characterized by dense vegetation and heavy fuel buildup. The primary objective of this project is to protect lives and property. Strategically placed fuel breaks, which slow the advance of wildfires and improve access for emergency responders, have the potential to prevent substantial losses of vulnerable homes and vital infrastructure, including regional high-voltage PG&E power lines and cell towers. The City is identified as a Community at Risk due to its proximity to extensive wildland fuels and the presence of numerous neighborhoods located in the WUI. Current conditions are characterized by high fuel loads in neighborhoods with limited accessibility for emergency vehicles and resident evacuations. To address these conditions, fuel break management in the hills around the Ukiah Valley has been identified as a crucial wildfire mitigation strategy by Mendocino County, CAL FIRE, and local fire chiefs. Implementation of this project will improve public safety, enhance emergency response capabilities and establish effective suppression opportunities by allowing firefighting crews to anchor suppression lines and prevent wildfires from encroaching into the sub-basin toward Ukiah. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 4 2.1.1 West Hills The PIZ is situated atop the hills directly west of Ukiah, CA. It comprises three main components: previously burned areas spanning 263 acres, areas designated for future controlled burns spanning 282 acres, and past/present control lines covering 453 acres. The previously burned areas were a result of the Ukiah Fuel Reduction Vegetation Management Plan (Project Number: RX NORTH-100 MEU) in March 2020, aimed at reducing overall fuel loads (see Figure 2.2-1). The land within the West Hills is owned by a mix of private landowners, the City, and the county. Currently, the West Hills area remains predominantly undeveloped, excluding existing firebreaks, private access roads, and an operational communication tower with its associated infrastructure. The area serves various purposes, including rural and remote residences, agricultural activities, wildlife management, and unsanctioned recreational use. One of the control lines on the ridge above Low Gap Park serves as an extension of the trail system, breaching private property boundaries up to the iconic Ukiah "U" landmark at the hill's summit. The City has recently proposed the acquisition and annexation of approximately 707 acres within the West Hills area, with the primary goal of preserving open space. This initiative may also allow for potential low-density residential development in the future, along with infrastructure improvements like utility extensions, road enhancements, and the construc tion of water tanks. The Ukiah West Hills VTP is the first phase of a multi-phase project. The Pomo Indians were the first inhabitants of the Ukiah Valley and its’ surrounding hills. The name “Ukiah” originates from a mistranslation of a Pomo word, “yokoyo” meaning “deep valley” (Preservation 2010). Native people stewarded the land for centuries, utilizing a variety of methods to support life and daily functions. Indigenous stewardship included wildlife habitat enhancement for hunting, maintenance of native grasses for baskets, and the use of wildland burning for other agricultural and vegetation management needs. In the mid to late 1800’s settlers of European descent came to the Ukiah Valley and displaced and/or destroyed native people and their land management practices. By the mid-1900’s fire suppression and exclusion became the standard practice, leading to densely vegetated landscapes and an overaccumulation of hazardous fuels. The West Hills span two distinct ecoregions: the Outer North Coast Ranges, which predominate in the northernmost portion of the project area, and the Sonoma-Mendocino Mixed Forest, which encompasses the southern part of the project area, stretching from the Crestview Drive ridge to Oak Knoll Road. The Napa -Sonoma-Russian River Valley region does not directly intersect with the project area but borders the lower foothills to the east. For detailed descriptions of each ecoregion, ple ase refer to Section 4.6. The vegetation within the cleared control lines primarily consists of native and non -native grasses and forbs, interspersed with patches of mixed hardwood-conifer trees and evergreen shrubs. Vegetation communities across the entirety of the West Hills are characterized by dense chaparral, predominantly comprised of chamise, and mixed hardwood -conifer woodlands. 2.2 PROPOSED TREATMENTS The proposed project involves two treatment types: (1) fuel breaks in critical defensive locations determined by CAL FIRE, which shall not exceed 300-feet in width; and (2) Wildland-Urban Interface fuel reduction (WUI) located within 1,000 feet of the interface layer mapped in the CAL FIRE WUI layer (WUI25_1). The vegetation treatment activities proposed to implement each of these treatment types are prescribed burning, mechanical treatment, manual treatment, and targeted ground application of herbicides. The treatment types and treatment activities are described below. Table 2-1 provides the proposed acres of treatment activities, and Table 2-2 provides a summary of the different treatment types. Refer to Figure 2.2-1 for the location of each of the existing or proposed treatment activities within the areas. 2.2.1 Treatment Types Table 2-1 Proposed Treatment Size by Area Treatment Areas CalVTP Treatment Type Maximum Treatment Area within CalVTP Treatable Landscape (acres) Maximum Treatment Area Outside CalVTP Treatable Landscape (acres) Maximum Total Treatment Area (acres) West Hills Fuel breaks 391 62 453 Wildland-Urban Interface 545 0 545 Total acres (approximately) 998 Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 5 FUEL BREAKS In strategic locations, fuel breaks create zones of vegetation removal, often in a linear layout, that reduce wildfire risk and support fire suppression by providing responders with a staging area or access to a remote landscape for fire control actions. They can also provide safe emergency egress during wildfires. Control lines will be preplanned and will be established utilizing an existing road and dozer trail network as much as feasible. Bulldozers may be employed to construct new control lines or re- scrape overgrown roads and skid/dozer trails down to mineral soil to ensure functionality prior to ignition. Control lines that employ the complete removal of vegetation will serve as fuel breaks. Handlines will be constructed in areas inaccessible to heavy equipment or where such use is necessary to avoid impacts to pre-identified sensitive resources (e.g., biological, cultural, geological, or other). Shaded fuel break prescriptions will be utilized adjacent to control lines that are adjacent to dense forested conditions . In forested areas, the tree canopy would be thinned to reduce the potential for a crown fire to move through the canopy; however, larger trees would remain. The shade of the retained canopy also helps reduce the potential for rapid regrowth of shrubs and sprouting hardwoods and may reduce rill and gully erosion. The shaded fuel breaks also provide important control lines for prescribed fire activities. Linear non-shaded fuel breaks (bulldozer control lines) will be utilized adjacent to shaded fuel breaks and range from 100-150 feet pending slope and terrain. Non-shaded fuel breaks are already established (but to be maintained) in some areas and any new ones would be established in areas along strategic topographic locations (e.g., on ridge tops); adjacent to roads, skid trails, and existing fuel breaks; and near high-use areas (e.g., cabins, infrastructure, parking areas, ranch roads), as shown in Figure 2.2-1. All shaded fuel breaks will occur within 100 feet of existing roads, skid trails, existing fuel breaks, and historic bulldozer lines. To create shaded fuel breaks, shrubs and understory trees would be removed to reduce surface and ladder fuels and create safer places for firefighters to stage equipment and fight wildfire. Live trees up to 1 2 inches diameter at breast height (DBH) would be felled; live trees greater than 12 inches DBH would be limbed up to 10–15 feet; and spaces of 15–20 feet width would be created between trees. In oak woodlands, treatment would focus on removing encroaching conifers and bay trees to promote protection of tree health in native oak woodland. WILDLAND-URBAN INTERFACE This project proposes a WUI treatment type to reduce hazardous fuels and lower wildfire risk in areas adjacent to residential neighborhoods, critical infrastructure, and evacuation routes. Implementing mechanical and manual vegetation removal, pile burning, prescribed fire, and selective herbicide application will modify existing fuels, reducing the likelihood of high-intensity, stand-replacing wildfires. WUI treatments will focus on thinning small-diameter trees from overstocked forest units and post-fire resprouts, removing dense understory vegetation, and eliminating excessive standing dead wood. Encroaching conifers, nonnative trees, and shrubs in oak woodlands may also be removed where they contribute to hazardous fuel conditions. Three to five snags per acre may be retained where they do not conflict with fuel -reduction objectives. The project area is located within the “Very High” hazard influence zone, as identified in the CAL FIRE WUI map (WUI25_1), and has experienced multiple large fires in recent decades. High fuel loads and limited egress make these areas particularly vulnerable to fast-moving wildfires. Implementing WUI treatments will reduce fire behavior, moderate wildfire spread, and protect life, property, and critical infrastructure. 2.2.2 Treatment Activities The proposed vegetation treatment activities are prescribed burning, pre-treatments of fuels (mechanical and manual), and targeted ground application of herbicides. Each of these treatment activities is described in more detail below and consisten t with the treatment activities described in the CalVTP. All treatment activities will occur in both areas. Table 2-1 provides the maximum acres of treatment types both within the SRA and the additional acres in the LRA, and a further breakdown and description of the proposed treatment types can be found in Table 2-2. Treatment activities could occur during any time of year, although the nesting bird season would be avoided when feasible. Although there is the potential for prescribed burning to occur during nighttime and weekend hours, all treatment activities using equipment would be limited to daytime hours on Monday through Friday. PRESCRIBED BURNING Prescribed burning consists of two general types, pile burning and broadcast burning (under burning). Pile and burn treatments are designed to reduce fuel continuity and intensity, thereby lowering wildfire severity and improving defensible space in hi gh- risk WUI settings. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 6 These treatments will promote a more natural, sustainable, and wildfire resilient native landscape. Pile burning: Biomass from manual and mechanical treatment would be piled using equipment (e.g., skid steer, tractor, bulldozer, or excavator) or hand crews and burned appropriately. Typically, dozers are equipped with a brush rake to reduce soil displacement and create “clean” piles. Pile burning would occur in an understory or in areas with little to no live overstory, including areas that have experienced previous wildfire. Broadcast burning may be used as a fuel-reduction treatment within WUI and fuel break treatment types to reduce hazardous biomass and fuel continuity. Treatments may occur in areas with grassland, shrub, woodland, or forest vegetation, or where fuel conditions warrant presc ribed fire. Mechanical, manual, or herbicide pretreatments may be implemented to facilitate safe and effective burning. Broadcast burning reduces fine and surface fuels and limits potential wildfire intensity and rate of spread near developed areas and strategic fuel break locations. Prescribed burning in the grassland areas would help control nonnative plant species and reduce fine fuels. CAL FIRE will implement an understory burn to partially remove understory and groundcover vegetation during periods when weather and vegetation conditions allow to conduct a low intensity burn to meet treatment objectives. Prescribed burning may require the construction of new control lines or enhancement of existing control lines using manual or mechanical treatments, primarily through mowing or using hand tools, but use of a skid steer may be required. Prescribed burning would require between 10 and 50 crew members, depending on size and site characteristics of the burn unit. Typically, each burn would last one day to one week. Equipment could include water trucks, fire engines, and chainsaws. The project proponent will comply with all applicable air quality requirements and procedures outlined by the Mendocino County Air Quality Management District. A Burn Plan has been developed for use on all prescribed burns for this project. PRE-TREATMENT OF FUELS /MECHANICAL VEGETATION TREATMENT Mechanical treatments would primarily include masticating target vegetation and chipping biomass from manual and mechanical treatment activities in addition to crushing and chaining dense brush in preparation for controlled burning. Equipment would include tracked equipment, such as tractors/skidders, chippers, masticators, and dozers equipped with a ball and chain. Up to four crew members may operate at the same time across the project area. Typically, treatments would require several days to several months to complete. Equipment would be operated on or within 100 feet of roads or skid trails in fuel break treatment areas and on existing roads or skid trails or on flat to moderate slopes in WUI treatment areas. Small-diameter trees, downed woody debris, and woody shrubs would be masticated to increase tree spacing and reduce fire fuel loads in targeted areas. The biomass would be disposed of via the process of mastication (which essentially mulches the vegetation). Resulting mastication will leave a layer of mulch behind to minimize any erosion and suppress weed invasion, while also allowing the existing seedbank below to germinate and give root systems the opportunity to resprout. In some areas where the chips are too great, prescribed burning may be used to dispose of chipped and masticated materials. Generally, mechanical treatments would: • Target and masticate live woody shrubs and trees up to 12 inches DBH; • Remove limbs of large trees up to 15 feet high; • Prune trees with multiple stems (e.g., madrone) to two or three stems per tree; • A dozer pulling a ball and chain behind to crush brush, altering the fuel composition to help prepare an area for a future controlled burn; • Masticate standing dead trees/shrubs and downed woody debris up to 24 inches in diameter, while retaining at least three to five snags per acre; • Maintain at least 35 percent relative final density of chaparral vegetation; • To the extent feasible, retain buckeye, mature madrone, true oaks, redwood, big-leaf maple, native shrubs (e.g., gooseberry and snowberry) and other desirable species; and • Target successional tree species, including tanoak, bay laurel, sprouting madrone, and Douglas fir, for thinning. Proposed activities consist of approximately 453 acres of mechanical treatments, including maintenance treatments within the 265 acres of previously existing shaded fuel break. Masticators will be used to treat dense stands of understory vegetation and ladder fuels and maintain a healthy overstory. Bulldozers equipped with ball and chains will be utilized in areas where dense brush requires pre-treatment fuel alterations to prepare an area for safe and effective controlled burning. As stated in the CalVTP PEIR Section 2.5.2, mechanical treatments may cut, uproot, crush/compact, or chop existing vegetation using masticators and other methods of application. This project proposes to limit mastication to the cutting or chopping of above-ground vegetation with the intent of keeping masticating heads out of duff layers and minimizing direct disturbance to subsurface soil layers, allowing intact root systems to resprout. Understory debris would be masticated or chipped on -site within the treated areas or piled and subsequently burned during wet periods of the year to dispose of accumulated biomass, pursuant to the standards defined in the PEIR (CalVTP Final PEIR Volume II Section 2.5.2, 22 -24). Mechanical treatments are efficient in removing dead, dying, and diseased trees and understory fuels over large areas of land to help mimic disturbance necessary for natural regeneration. The mechanical treatment crew may utilize a chainsaw and/or various other mechanized Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 7 tools or hand tools to buck downed debris and prune ladder fuels and vegetation. PRE-TREATMENT OF FUELS /MANUAL VEGETATION TREATMENT As described in the CalVTP PEIR Section 2.5.2, manual treatments consist of the use of hand tools and hand -operated power tools to cut, clear, or prune herbaceous or woody species. Ground disturbance during manual treatments is typically less than that of mechanical treatments, allowing for treatments to be carried out in sensitive habitats, wet areas, and riparian corridors or areas where mechanical, herbicide, or prescribed burning treatments are not feasible or appropriate. Vegetation debris accumulated after manual treatments would be lopped and scattered on-site within the treated areas or piled and subsequently burned during wet periods of the year to dispose of accumulated biomass, pursuant to the standards defined in the PEIR (CalVTP Final PEIR Volume II Section 2.5.2, 22-25). To implement manual treatments, physical labor crews of approximately eight to 20 members would use hand tools and hand- operated power tools, including chainsaws, hand saws, brush cutters, and loppers, to cut, clear, and/or prune trees, herbaceo us vegetation, and woody shrubs and increase space betwee n trees. Typically, treatments would require several days to several months to complete, depending on the treatment size, steepness of terrain, and type and density of vegetation. Trees would be removed, thinned, and pruned and woody shrubs would be cut and cleared. In forested areas, the focus would be on thinning/cutting dense standing dead wood, including dead trees up to 24 inches DBH, while retaining three to five snags per acre for wildlife habitat. In oak woodland habitat, the focus would be on the removal of Douglas fir trees to reduce oak tree shading and therefore promote oak woodland habitat. Where feasible, treatments would focus on removing nonnative and invasive species. Manual treatment activities may also be implemented in sensitive areas, such as within 100 feet of Class II or III streams to improve habitat and reduce undesirable wildfire hazards, in areas with steeper slopes (greater than 40%), or near cultural resources. Manual treatment within 100 feet of Class II or III streams would also occur outside of bird nesting season if feasible. Only manual treatments will be conducted in Class III Equipment Exclusion Zones (EEZs). Cut vegetation will be left on site by lopping or chipping and scattering on the landscape. In some areas, removed vegetation would be piled for later pile burning or broadcast burning. The same general guidelines for tree and vegetation removal and retention would be followed as described above for mechanical treatments. HERBICIDE APPLICATION Herbicides would be used sparingly to control vegetation that threatens the native biodiversity and/or increases wildfire haz ards. Post-wildfire invasive plant and noxious weed infestations may need to be treated to prevent their establishment such that limited herbicide application may be considered where invasive species are present or expected to occur within the treatment areas to promote regeneration of native species and reduce the spread of invasive vegetation. Herbicide treatment is expected to occur near roads and trails where increased sunlight is present, which will significantly reduce the actual acreage to which herbicide is applied. Herbicides will not be utilized within WLPZs or EEZs and will be predominantly focused where invasive plants (such as French broom and yellow star thistle) are expected to occur (e.g., sunlight openings). Consistent with the definitions applied in the CalVTP, invasive species are those plant species identified as invasive by the California Invasive Plant Council (Cal-IPC) or defined as noxious weeds under California law by the California Department of Food and Agriculture. The occasional use of herbicides to treat invasive plant species and to control regrowth of native tree species (e.g., resprouting, multiple-stemmed tanoak, bay laurel, and madrone) may be implemented to promote native biodiversity. The CalVTP PEIR Section 2.5.2 indicates that herbicide application may only be implemented at ground -level from equipment on vehicles or by manual application devices and must comply with the U.S. Environmental Protection Agency directions, as well as California Environmental Protection Agency and Department of Pesticide Regulation label standards. While herbicide application is not anticipated to be a primary treatment activity for this project, it may be used in conjunction with other treatment activities to control the colonization and spread of invasive plants following initial treatments. More detailed information on herbicide activities can be found in the Environmental Checklist below. The following herbicides, which are consistent with those considered for use in the CalVTP, may be applied: • Glyphosate, and • other species-specific herbicides analyzed and included in the CalVTP PEIR. Only ground-level application would occur; no aerial spraying of herbicides would occur. The least impactful method would be used at any given site. Several herbicide application methods are available for use by on -the-ground personnel, including paint-on stems and using backpack hand-applicators. For large treatment areas, herbicide treatments would typically use a one- to five-person crew, a 4x4 pickup truck, a porta-potty, a passenger vehicle to transport crew, a utility task vehicle (UTV) with Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 8 a sprayer/reservoir tank, and backpack sprayers. Treatment would involve removing invasive plant species (e.g., French broom, leafy spurge) and noxious weeds through herbicide application. All herbicide applications would be performed by certified and licensed pesticide applicators in accordance with all local, state, and federal regulations. BIOMASS DISPOSAL The proposed vegetation treatments described above would be disposed of primarily by the following means: • Masticating (mulching) vegetative debris and placing it on the ground concurrently with vegetation removal (approximately ten percent of biomass), and the biomass remaining after mastication would be no more than six inches deep; • Chipping (approximately 20 percent of biomass); materials within 100 feet on either side of a road, and chipped biomass would be spread over treatment areas and would not exceed six inches in depth; • Lopping and scattering within the treatment boundaries (approximately 20 percent) and would be left within 18 inches of the ground to promote decomposition; • Pile burning (approximately 20 percent of biomass), which may be used to dispose of slash, chipped, and masticated materials; or • Broadcast burning (approximately 30 percent of the biomass). Invasive plant and noxious weed biomass would be treated onsite to eliminate seeds and propagules or would be disposed of off-site at an appropriate waste collection facility to prevent re-establishment or spread of invasive plants and noxious weeds. Invasive plants and noxious weeds would not be chipped and spread, scattered, or mulched on-site. These kinds of treatments create an opportunity for CAL FIRE to stop or manage a wildfire, potentially reducing ground disturbing emergency actions such as creating control lines with bull dozers which create additional environmental impacts. Techniques such as minimum impact suppression (e.g., “back burning”; which is setting a fire in controlled conditions to reduce fuel loading before the head of the fire arrives) may be utilized in areas where strategic fuels reduction treatments have occurred years ahead of a wildfire.

Several days to weeks 2.3 RETREATMENT/TREATMENT MAINTENANCE Retreatment for maintenance of desired vegetation conditions (referred to as “treatment maintenance” in the CalVTP PEIR and referred to as “retreatment/treatment maintenance” or “maintenance” in this PSA/Addendum) in the areas initially treated for the proposed project would follow the existing general land management practices and would be based on real -time monitoring of site conditions (see Table 2-3). In forested and woodland areas, retreatment is anticipated to occur every 2-5 years. In areas where initial treatment included removing multiple stems from stump-sprouting vegetation (e.g., madrone, California bay) retreatment would occur every 2-5 years. Retreatment/treatment maintenance methods would involve the same vegetation treatment activities used in the original t reatment; however, the City anticipates the use of more hand crews than mechanical equipment in comparison to initial treatments. Retreatment/treatment maintenance would typically be implemented between approximately August and January, outside of the nesting bird season, if feasible. Periodic retreatment/treatment maintenance will occur as needed, determined by qualifie d staff who would monitor vegetation growth conditions over time. Retreatment/treatment maintenance could occur in a variety of methods and management activities. Each of these activities may have a distinct timeline dictated by the intent of the activity, its effectiveness at managing vegetation growth and establishment, and the overall impact on other environmental resources. The following table describes retreatment/treatment maintenance activities that have the potential to take place in the lifespan of this project. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 10 Table 2-3 Retreatment/Treatment Maintenance Activities Retreatment/Treatment Maintenance Activity Treatment Description Implementation Timeline Rate of Retreatment Vegetation thinning and/or removal to maintain shaded fuel breaks Manual – Hand crews with chainsaws, weed-whackers, loppers, and other hand tools would remove vegetation that has grown into the understory of the shaded fuel break and into the operable space of the dozer and control lines. Mechanical masticators, skidders, and dozers are used to thin/completely remove unwanted vegetation in the dozer control lines and in the understory of the shaded fuel breaks. Manual and Mechanical – ideally occurs August – January (outside of the nesting bird season), however if work occurs February – July, nesting bird surveys will be completed ahead of operations. Mechanical – Any use of heavy equipment during the Winter Period (November 15th – April 1st) shall NOT occur during saturated soil conditions. 2-5 years Pile burning Larger material that is removed during thinning/removal treatments may be piled and burned. Burning shall take place after CAL FIRE has lifted the burn ban in Mendocino County and after a Smoke Management Plan has been attained from the Mendocino County ACQB. 2-5 years, if necessary, at all. Herbicide application to prevent unwanted brush growth, sprouting, and establishment of invasive species. Herbicide application will occur in the form of foliar application and stump applications. Herbicide application is most effective when done in the fall months (September-November). The herbicide application should be done on dry days with no or low wind speeds. Annually for the first two years, and sporadically if invasive species begin to reestablish. As previously stated, the need for retreatment/treatment maintenance activities will be determined using on -site monitoring in the months and years following the implementation of this project. Retreatment/treatment maintenance activities will be deemed necessary when the intent of the project is no longer being met. In other words, if vegetation regrowth is negatively impacting fuel loading and the ability to maintain defensible space, then retreatment/treatment maintenance activities are necessary.

Description of the Project: (Describe the whole action involved, including any phasing of initial treatments as well as planned treatments, including equipment to be used and planned duration of treatments, but not limited to later phases (e.g., maintenance) of the project, and any secondary, support, or off-site features necessary for its implementation. Attach additional sheets if necessary.) Treatments would involve prescribed burning, mechanical and manual treatments, and herbicide application. See Section 2.2, above for additional details. 9.

See Section 2.3, above for additional details. 12. Geographic Scope [Refer to [to be determined] for a map of the CalVTP treatable landscape, check one box] ☐ The treatment site is entirely within the CalVTP treatable landscape. ☒ The treatment site is NOT entirely within the CalVTP treatable landscape . Approximately 702 acres of the 5,961-acre project area is mapped outside of the treatable landscape polygon associated with the CalVTP PEIR. The areas not encompassed by the treatable landscape polygon include 78 acres within the FRA (but are not proposed for treatment under this VTP) and 624 acres that are within the LRA and are proposed for treatment under this VTP. After onsite field evaluation and environmental analysis of the project area consistent with the CalVTP PEIR, it was determined that the entire project area is within the treatable landscape because the existing environmental conditions in the areas outside the treatable landscape are essentially the same as those within the treatable landscape. The vegetation, geology, and slopes are representatively the same as those sections of the project area within the treatable landscape. There are no changes in vegetation type, composition and structure nor changes in fuel load/conditions relative to the adjacent areas of treatable landscape. 13. Regional Setting and Surrounding Land Uses: (Briefly describe the project’s surroundings) The proposed CalVTP treatments would occur on the City of Ukiah lands as well as private ownership lands in Mendocino County. Pole The project is in the Russian River Watershed near the headwaters; the area has a long history of ranching and logging and contains areas of scattered residences. 14. Other Public Agencies Whose Approval Is Required: (e.g., permits) A pesticide application permit would be obtained from the Mendocino County Agricultural Commissioner.

The proposed project is within the Coastal Zone (check one of the following boxes) A coastal development permit has been applied for or obtained from the local Coastal Commission district office or local government with a certified Local Coastal Plan, as applicable. The local Coastal Commission district office or local government with a certified Local Coastal Plan (in consultation with the local Coastal Commission district office) has determined that a coastal development permit is not required. 15. Native American Consultation. Pursuant to PRC Sections 21080.3.1, 21080.3.2, and 21082.3, lead agencies undertaking CEQA review must, upon written request of a California Native American tribe, begin consultation before the release of an environmental impact report, negative declaration, or mitigated negative declaration. For treatment projects that require additional CEQA review and documentation, have California Native American tribes traditionally and culturally affiliated with the project area requested consultation pursuant to Public Resources Code section 21080.3.1? If so, is there a plan for consultation that includes, for example, the determination of significance of impacts to tribal cultural resources, procedures regarding confidentiality, etc.? Note: For treatment projects that are within the scope of this PEIR, AB 52 consultation has been completed. The Board of Forestry and Fire Protection and CAL FIRE completed consultation pursuant to Public Resources Code section 21080.3.1 in preparation of the PEIR. As the MCFSC pursues its mission of helping residents of Mendocino County protect their families and homes from wildfire, we recognize that we stand upon the unceded ancestral lands of many Indigenous peoples. We honor their knowledge, care, and stewardship of this special place across the ages and acknowledge the deep and lasting damage that colonization has inflicted on them. We embrace our responsibility to learn from and protect their cultural and traditional connections to the land. Pursuant to CalVTP SPR CUL-2, Native American tribal contacts in Mendocino were contacted on February 1, 2024, and included every Native American contact provided on the September 20th, 2023,. A discussion regarding specific cultural resources and a list of proposed protection measures are in the 2024 confidential Archaeological Survey Report for this project. If additional treatment units are scheduled, another phase of archaeological review will be conducted. 16. Use of PSA for Treatment Maintenance: [Prior to implementing a maintenance treatment, the project proponent would verify that the expected site conditions as described in the PSA are present in the treatment area. As time passes, the continued relevance of the PSA would be considered by the project proponent in light of potentially changed conditions or circumstances. Where the project proponent determines that the PSA is no longer sufficiently relevant, the project proponent would determine whether a new PSA or other environmental analysis is warranted. In addition to verifying that the PSA continues to provide relevant CEQA coverage for treatment maintenance, the project proponent would update the PSA at the time a maintenance treatment is needed when more than 10 years have passed since the approval of the PSA or the latest PSA update. For example, the project proponent may conduct a reconnaissance survey to verify that conditions are substantially similar to those anticipated in the PSA. Updated information should be documented.] Prior to retreating any area within the project boundary, the project proponent will verify that site conditions described in the PSA are still relevant. CAL FIRE’s contract with the landowners is for 10 years. After 10 years, the landowner can enter into a new agreement with CAL FIRE, and the project proponent will re-evaluate environmental conditions and prepare a new PSA if necessary. If a new contract is not initiated, it is at the discretion of the landowners to maintain the project area if desired. 17. Standard Project Requirements and Mitigation Measures. [Refer to Attachment A to identify which SPRs and Mitigation Measures apply to the project. Complete Attachment A to document the responsible party for each applicable SPR and Mitigation Measure. Check one box below.] All applicable SPRs and Mitigation Measures are feasible and will be implemented There is NO new information which would render mitigation measures previously considered infeasible or not considered in the CalVTP PEIR now feasible OR such mitigation measures have been adopted. [Guidelines Sec.15162(a)(3); PRC Sec. 21166(c)] Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 15 All applicable SPRs and Mitigation Measures are NOT feasible or will NOT be implemented (provide explanation) DETERMINATION On the basis of this initial evaluation: I find that all of the effects of the proposed project (a) have been analyzed adequately in the CalVTP PEIR, (b) have been avoided or mitigated pursuant to the CalVTP PEIR, and (c) all applicable mitigation measures and Standard Project Requirements identified in the CalVTP PEIR will be implemented. The proposed project is therefore WITHIN THE SCOPE of the CalVTP PEIR. NO ADDITIONAL CEQA DOCUMENTATION is required. I find that the proposed project will have effects that were not examined in the CalVTP PEIR. These effects are less than significant without any mitigation beyond what is already required pursuant to the CalVTP PEIR. A NEGATIVE DECLARATION will be prepared. I find that the proposed project will have effects that were not examined in the CalVTP PEIR. Although these effects might be significant in the absence of additional mitigation beyond what is already required pursuant to the CalVTP PEIR, revisions to the proposed project or additional mitigation measures have been agreed to by the project proponent that would avoid or reduce the effects so that clearly no significant effects would occur. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project will have environmental effects that were not examined in the CalVTP PEIR. Because these effects are or may be significant and cannot be clearly mitigated, an ENVIRONMENTAL IMPACT REPORT will be prepared.

The details of the SPRs and MMs can be found in Attachment A. The information included should provide clarity for review the and/or provide direction to the field staff that will implement the project utilizing the checklist. Information included considers whether the proposed project would result in new or more substantial environmental effects than described in the CalVTP PEIR, after incorporation of applicable SPRs and MMs required by the CalVTP PEIR. All answers considered the whole action involved, including off-site as well as on-site, cumulative as well as project-level, indirect as well as direct, and short-term as well as long-term impacts. Once the environmental effects that may occur were evaluated, the checklist indicates the weight of the impact. Weight of impact was characterized utilizing the definitions located in Chapter 3 – “Environmental Settings, Impacts, and Mitigation Measures, 3.1.4 – Terminology Used In the PEIR” and are as follows: - Less Than Significant (LTS) - An impact either on its own or with incorporation of SPRs, does not exceed the defined thresholds of significance (no mitigation required), or that is potentially significant and can be reduced to less than significant through implementation of feasible mitigation measures. - Less Than Significant with Mitigation (LTSM) - An impact was identified within the PEIR which was viewed in totality as potentially significant and/or significantly unavoidable and the mitigation measures and SPRs and MMs provided in the PEIR will be implemented mitigating to a point of less than significance. - Potential Significant (PS) - An impact treated as if it were a significant impact. “Potentially” is used to convey that not every qualifying treatment will result in impacts to the reasonably maximum degree that they are disclosed in this PEIR. - Potentially Significant and Unavoidable (PSU) - An impact is considered significant and unavoidable if it would result in a substantial adverse change in the environment that cannot be feasibly avoided or mitigated to a less-than- significant level. “Potentially” is used to convey that not every qualifying treatment will result in impacts to the reasonably maximum degree that they are disclosed in this PEIR. - Significantly Unavoidable (SU) - An impact is considered significant and unavoidable if it would result in a substantial adverse change in the environment that cannot be feasibly avoided or mitigated to a less-than-significant level. - Not applicable (N/A) Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 17 4.1 AESTHETICS & VISUAL RESOURCES Impact in the PEIR Project-Specific Checklist Environmental Impact Covered in the PEIR Identify Impact Significance in the PEIR Identify Location of Impact Analysis in the PEIR Does the Impact Apply to the Treatment Project?

The potential for these treatment activities to result in short-term degradation of the visual character of a treatment area was examined in the PEIR. The eligible state scenic highway nearest to the project area is SR 20 (Caltrans 2023). The proposed treatments would not occur on lands adjacent; however, public viewpoints of the project area are available from public recreation trails, adjacent residences and winerie s, Highway 101, and SR 20. Visibility of treatment areas would be limited from the highways and no vegetation would be removed immediately adjacent to the highways. However, smoke from prescribed burning could be visible from public viewpoints, Highway 101, and SR 20. Although some burn units may be noticeable after treatment, the degree of vegetation change is expected to be minimal and not impact the natural aesthetics or character of the landscape over the long term. Short-term vegetation charring will be noticeable but will be replaced by new plant growth during the next growing season. Prescribed burning will occur under ideal conditions for a low intensity, controlled mosaic burn; thus, activities would be temporary. Smoke generated from prescribed burning will be short-term, and burning will adhere to a Smoke Management Plan (SMP) (SPR AQ-2) and a Burn Plan (SPR AQ-3). The equipment, vehicles, and any vegetation treatment debris associated with the activities proposed in this project will not block or disrupt views. The potential for the project to result in short-term substantial degradation of the visual character of the project area is within the scope of the PEIR because the proposed treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape cons titutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing scenic resources are essentially the same within and outside of the treatable landscape; therefore, the short- term aesthetic impact is also the same, as described above. SPRs applicable to the proposed treatments are AD-4, AD-6, AES-1, AES-2, AES-3, AQ-2, AQ-3, and REC-1. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AES-2 Initial and maintenance treatments would include shaded and non-shaded fuel break, and WUI treatment types. The potential for these treatment types to result in long-term degradation of the visual character of an area was examined in the PEIR. Public viewpoints of the project area include public recreation trails, adjacent residences, and wineries. The project area is visible from SR 20; however, visibility of treatment areas would be limited from the highway and no vegetation would be removed immediately adjacent to the highway. The potential for the project to result in long-term substantial degradation of the visual character of the project area is within the scope of the PEIR because the proposed treatment activities are consistent with those analyzed in the PEIR.

This determination is consistent with the PEIR and would not constitute a more severe impact than what was covered in the PEIR. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AES-3 Initial and maintenance treatments would include the non-shaded fuel break treatment type in the form of reestablishing and maintaining existing dozer/control line infrastructure. The potential for non-shaded fuel breaks to result in long-term degradation of the visual character of an area was examined in the PEIR. Public viewpoints of the project area include public recreation trails, adjacent residences, and wineries. The project area is visible from SR 20; however, visibility of treatment areas would be limited from the highway and no vegetation would be removed immediately adjacent to the highway. Non- shaded fuel breaks have been installed and will continue to be maintained in strategic locations along ridgelines. Non -shaded fuel breaks meander topographically along ridgelines, helping them to blend into the natural topography of the landscape. Furthermore, because of the strategic nature of non-shaded fuel break locations, it is infeasible to relocate these non-shaded fuel breaks to avoid public visibility per Mitigation Measure AES-3. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 19 Non-shaded fuel breaks already exist on the landscape from past emergency fire suppression operations. These dozer lines, while visible from Ukiah, have become a part of the landscape and CAL FIRE has not received pushback from the local community regarding their existence. This project proposes to maintain these past control lines as part of a strategic fuel break network adjacent to the city of Ukiah. The potential for the project to result in long-term substantial degradation of the visual character of the project area is within the scope of the PEIR because the proposed treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing visual character is essentially the same within and outside of the treatable landscape; therefore, the long-term aesthetic impact is also the same, as described above. SPRs applicable to the proposed treatments are AD-3, AD-4, AES-1, AES-2, AES- 3, AQ-2, AQ-3, and REC-1. This determination is consistent with the PEIR and would not constitute a more severe impact than what was covered in the PEIR. As was previously stated, Mitigation Measure AES-3 is not applicable due to the fact that the non-shaded fuel break infrastructure is already in place, therefore the location of these fuel breaks cannot be changed. As much as is feasible, vegetation adjacent to the non-shaded fuel breaks will be feathered to break up the linear edges of the fuel break and strategically preserve vegetation at the edge of the fuel break to help screen public views and minimize the contra st between fuel break and surrounding vegetation. NEW AESTHETIC & VISUAL RESOURCE IMPACTS The proposed treatments are consistent with the treatment types and activities covered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.2.1, “Environmental Setting,” and Section 3.2.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions pertinent to aesthetics and visual resources that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are consiste nt with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impact. Therefore, no new impact related to aesthetics and visual resources would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.2.1 Agriculture & Forestry Resources Discussion The project area is primarily comprised of chapparal, brush, and scrub land with some scattered concentrations of hardwoods and conifers (particularly in the drainages). The project area parcels are primarily zoned as “Agricultural” or “Residential” and are not zoned for timber production. Initial and maintenance treatments will encourage healthier ecosystem conditions by removing competing vegetation. The treatments will protect adjacent forest and woodland from stand-replacing wildfire. IMPACT AG-1 Vegetation treatment activities within the project area would include manual, mechanical, prescribed burning, and limited herbicide treatments implemented as Wildland-Urban Interface (WUI) and fuel break treatments. The project is a critical wildfire safety project located around the City of Ukiah and is designed to protect critical infrastructure, residential area s, and other values at risk from wildfire. Shaded fuel breaks would be established by thinning tree canopies in forested areas through removal of live trees up to 12 inches DBH, limbing of larger trees to approximately 10 to 15 feet and increasing spacing between trees to reduce canopy continuity. Fuel breaks would be strategically located within approximately 100 feet of existing roads, skid trails, existing fuel breaks, or historic dozer lines to minimize new ground disturbance and avoid effects to adjacent land uses. WUI treatments would focus on reducing hazardous fuels, including thinning small-diameter trees and post-fire resprouts, to improve fire behavior conditions near developed areas and infrastructure. Prescribed burning would be implemented primarily in brush and shrub-dominated areas, with limited conifer and hardwood presence, under controlled conditions that would not result in conversion of forestland. Where overstory trees occur, prescribed fire may improve their resilience by reducing competing vegetation and surface fuels. Both initial and maintenance treatments are designed to reduce the risk of stand -replacing wildfire, maintain existing forest Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 21 cover where present, and support long-term wildfire protection objectives for the Ukiah area. As a result, the project would not result in the conversion of forestland or agricultural land and is consistent with the CalVTP PEIR analysis for Impact AG -1. The potential for any of the proposed treatment types and treatment activities to result in the loss of forestland or conversion of forestland to non-forest use was examined in the PEIR. The treatment activities proposed in this project occur primarily in chapparal, brush, and scrub land ecosystems with some scattered concentrations of hardwoods and conifer. The shaded fuelbreak treatments in the forested portions of the project area are aimed at reducing ladder fuels and hazardous fuel l oading so that wildfire spread, and severity is less likely and lower intensity/severity overall . The goal of this project is to protect and enhance existing ecosystems both within and adjacent to the project area. Treatments are aimed at increasing resilience and resistance of these ecosystems to catastrophic wildfire. Therefore, conversion is not a goal, nor will it be a product of this project. Consistent with the PEIR, the vegetation remaining after treatments would meet the definition of forestland as defined in Public Resources Code Section 12220(g), which defines “forest land” as land that can support 10-percent native tree cover of any species under natural conditions. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the composition of forested land as defined in Public Resources Code Section 12220(g) is essentially the same within an d outside the treatable landscape; therefore, the impact to forest land is also the sam e, as described above. No SPRs are applicable to this impact. Therefore, the potential for the project to result in the loss or conversion of forestland is within the scope of the PEIR. This impact of the proposed project is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW AGRICULTURE & FORESTRY RESOURCE IMPACTS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.3.1, “Environmental Setting,” and Section 3.3.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions present in the areas outside the treatable landscape are essentially the same as thos e within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to new significant impacts not addressed in the PEIR. Therefore, no new impact related to agriculture and forestry resources would occur that is not covered in the PEIR.

It is not expected that smoke from this burn will affect air quality in either Lake or Sonoma County. Primary smoke receptors for the project are the nearb y communities of Ukiah, Talmage, Calpella, as well as residences located in Yokayo Valley and along HWY 101. Burning under conditions specified in the prescription will mitigate adverse smoke impacts. Smoke columns will be visibly monitored for direction and lift to evaluate smoke dispersal/transport predictions. Personnel will be assigned to observe smoke dispersal as necessary. The burn will be curtailed if the planned convective lift and/or planned dispersal cannot be achieved. Smoke dispersal conditions will be evaluated in the morning, at the test burn, and continually monitored throughout the durat ion of the project. On-site monitoring will include weather, smoke, and fire behavior observations. Additional information will be collected from the Ukiah, Hopland, and Boonville RAWS located southwest and southeast of the project area. Estimated mixing heights and upper level transport winds will be obtained from the Redding Interagency Fire/Forecast Warning Unit internet site at: www.fs.fed.us/r5/fire/north/fwx/smok.txt or at the National Weather Service-Eureka spot forecast internet site at: http://www.wrh.noaa.gov/eka/. To minimize daily and cumulative air quality impact to the regional area, the project will be scheduled in coordination with the Mendocino County AQMD, Northern Sonoma County NSCAPCD, the Lake County AQMD, and any other local private or agency prescribed fire projects. Pursuant to SPR AQ-2, CAL FIRE will prepare a smoke management plan and submit it to the air district with jurisdiction over the treatment area(s) where prescribed burning is proposed before implementing a prescribed burning treatment, if required. Pursuant to SPR AQ-3, a burn plan will be prepared for broadcast burning, will include fire behavior modeling, and will be implemented by a state-certified burn boss, as required. An Incident Action Plan, which identifies burn dates, burn hours, weather limitations, specific burn prescription, the communication plan, the medical plan, the traffic plan, and other special instructions will also be prepared by CAL FIRE for all proposed prescribed burning treatments. The Incident Action Plans will also identify the contact personnel with the applica ble air district to coordinate on-site briefings, posting notifications, and weather monitoring during burning. IMPACT AQ-1 Use of vehicles, mechanical equipment, and prescribed burning during initial and maintenance treatments would result in emissions of criteria pollutants that could exceed California ambient air quality standard (CAAQS) or national ambient air quality standard (NAAQS) thresholds. The potential for emissions of criteria pollutants to exceed CAAQS or NAAQS thresholds was examined in the PEIR. Emissions of criteria air pollutants related to the proposed treatments are within the scope of the PEIR because the associated equipment and duration of use are consistent with those analyzed in the PEIR. The SPRs applicable to this treatment project are AD-4, AQ-1 through AQ-4, AQ-5, and AQ-6. Additionally, the emission reduction techniques included in Mitigation Measure AQ-1 would be implemented. The project proponent will reduce exhaust emissions from vehicles and equipment by only using the necessary amount of holding resources, encouraging carpooling to the project area, and using Best Available Control Technology for emission reductions for off-road equipment and diesel trucks. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR, and with MM AQ-1 the impact is considered less than significant with the mitigation measure. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions present and air basins in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the air quality impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AQ-2 Use of vehicles and mechanical equipment during initial and maintenance treatments could expose people, such as hikers in the project area, to diesel particulate matter emissions. However, treatment activities would not take place near the same people for an extended period. The potential to expose people to diesel particulate matter emissions was examined in the PEIR. Diesel particulate matter emissions from the proposed treatments are within the scope of the PEIR because the exposure potential is the same as analyzed in the PEIR, and the types and amount of equipment that would be used, as well as the duration of use, during proposed treatments are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions and sensitive receptors (i.e., exposure potential) present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the air quality impact is also the same, as described above. SPR HAZ-1 and NOI-2, NOI-4, and NOI-5 are applicable to this Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 24 treatment. Additionally, MM AQ-1 will mitigate further the diesel particulate emissions. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AQ-3 Use of mechanical equipment during treatments would involve ground-disturbing activities. Pile and broadcast burning would not involve ground disturbance although preparation for burning could require some disturbance, such as when dragging vegetation around or implementing control lines. The potential to expose people to naturally occurring asbestos containing fugitive dust emissions was examined in the PEIR (CalVTP Final PEIR Volume II Section 3.4.3, pages 3.4 -34–3.4-35). This impact would apply to the project area because there are two small pockets of serpentinite/ultramafic rock mapped in the treatment area by CGS in 2020 and 2022. Please see Section 4.6 Geology, Soils, Paleontology, and Mineral Resources for a discussion on serpentine and geologic background. There is a disjointed band of serpentine that runs northwest at the base of the hills along the Ukiah Valley. The first area within the PIZ is in the northeastern corner and the second is along Oak Knoll Road, as shown in Figure 4.6-2. Most of the project area is mapped as graywacke sandstone (slightly metamorphosed) with mélange to the north and south. These units are parts of the Franciscan Complex, which could contain smaller unmapped bodies of serpentine outcroppings or other lithologies favorable for presence of NOA. The larger landslide feature to the west of the Oak Knoll Road occurrence of serpentine has a higher potential for metals and NOA than the other surrounding landslide deposits, however the amount and concentration would depend on the source of the debris. Both serpentine locations contain existing control lines from previous fire suppression activities and additional ground disturbance is not proposed to maintain these areas. The soils mapped by The Soil Conservation Service do not have serpentine in their descriptions, however Mendocino County does identify some soils on the main trending ridge as possibly serpentine soils. As discussed in the PEIR, pile burning and ground disturbing activities such as vehicle and heavy equipment usage could resul t in naturally occurring asbestos becoming airborne. In accordance with SPR AQ-1, project proponents will comply with the rules and regulations laid out by the Mendocino County Air Quality Management District (MCAQMD) of the California North Coast Air Basin. Consultation with California Geological Survey (CGS) during project design identified se veral areas within the project area that may contain naturally occurring Asbestos (NOA). Per SPR AQ-5, no ground-disturbing activities would occur in these areas unless an Asbestos Dust Control Plan is prepared and approved by MCAQMD. The proposed project would also implement SPR AQ-4, which minimizes fugitive dust emissions during treatment activities. Potential naturally occurring asbestos exposure from the proposed treatments would be less than significant and is within the scope of the activities and impacts addressed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a minor chang e to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape because they are immediately adjacent each other and are underlain by the same type of serpentine soils and would involve similar or the same types of ground-disturbing activities. Therefore, the air quality impact is also the same, as described above, and would also be less than significant with the implementation of the same SPRs. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AQ-4 Prescribed burning during initial and maintenance treatments could expose people to toxic air contaminants, which was examined in the PEIR. The duration and parameters of the prescribed burns are within the scope of the activities addressed in the PEIR, and within the North Coast Air Basin, air quality conditions are consistent with those analyzed in the PEIR for Mendocino County. Therefore, the potential for exposure to toxic air contaminants is also within the scope the PEIR. SPRs applicable to these treatment activities are AD-4, AQ-2, AQ-3, and AQ-6. All feasible measures to prevent and minimize smoke emissions, as well as exposure to smoke, are included in SPRs. No additional mitigation measures are feasible, and this impact would remain significant and unavoidable, as explained in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions present and air basins in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the air quality impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AQ-5 Use of vehicles and mechanical equipment during initial and maintenance treatments could expose people, such as hikers in/around the project area, to objectionable odors from diesel exhaust. However, treatment activities would not take place near the same people for an extended period. The potential to expose people to objectionable odors from diesel exhaust was examined Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 25 in the PEIR. This impact is within the scope of the PEIR because the exposure potential and the proposed activities, as well as the associated equipment and duration of use, are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions, and sensitive receptors present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the air quality impact is also the same, as described above. SPR HAZ -1 and NOI-4 and NOI-5 are applicable to this treatment. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT AQ-6 Prescribed burning during initial and maintenance treatments could expose people to objectionable odors. The potential to expose people to objectionable odors from prescribed burning was examined in the PEIR. The duration and parameters of the prescribed burn and the exposure potential are consistent with the activities addressed in the PEIR. Therefore, the resultant potential for exposure to objectionable odors from smoke is also within the scope of impacts covered in the PEIR. SPRs that are applicable to this treatment project are AD-4, AQ-2, and AQ-6. All feasible measures to prevent and minimize smoke odors, as well as exposure to smoke odors, are included in SPRs. No additional mitigation measures are feasible, and this impact would remain significant and unavoidable, as explained in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the air quality conditions present and sensitive receptors in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the air quality impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe signific ant impact than what was covered in the PEIR. NEW AIR QUALITY IMPACTS The proposed treatments are consistent with the treatment types and activities covered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable regulatory and environmental conditions presented in the CalVTP PEIR (refer to Section 3.4.1, “Regulatory Setting,” and Section 3.4.2, “Environmental Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the p roject area, the existing environmental and regulatory conditions pertinent to air quality that are present in the areas outside the treatable landscap e are essentially the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impact. Therefore, no new impact related to air quality would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.4.1 Archaeological, Historical & Tribal Cultural Resources Discussion Consistent with SPR CUL-1, an updated records search of the PIZ was performed by the Northwest Information Center (NWIC) at Sonoma State university (SSU). Three separate Archaeological Records Check Requests were made, as the PIZ expanded in total size and acreage as more stakeholders became involved. The entire area submitted to NWIC for a records check (the sum of all three records check results) will be referred to here as the PIZ. The first NWIC Archaeological Records Check was completed on March 27, 2023 (NWIC File No. 22-1392). The area submitted under this information request included the West Hills of Ukiah. A second NWIC Archaeological Records Check was completed on October 27, 2023 (NWIC File No. 233 - 0491). The third and final NWIC Archaeological Records Check was completed on November 30, 2023 (NWIC File No. 23- 0674). The area submitted under the second and third information requests included the majority of the parcels to the east of the first information request, butting up against the higher density residential neighborhoods at the base of the western hills. RESULTS OF NWIC INFORMATION REQUESTS: The NWIC results for the three information requests can be found in the Confidential Archaeological Survey Report (ASR) which was prepared for the Treatment Units within the PIZ. Consistent with SPR CUL-2, a Native American contact list was obtained from The CAL FIRE Native American Contact List (revised September 20, 2023) published on their website. On February 1, 2024, letters or emails inviting the tribes to consult were mailed to the 32 different tribal representatives as disclosed on the Native American Contact List. No responses were Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 27 received from any Native American tribes as of Ma y 23, 2025. Consistent with SPR CUL-3, pre-field research was conducted. Archaeologically trained resource professionals reviewed historic and contemporary maps, aerial photographs, records, ethnographic literature, and historical literature. This information can be found in the Archaeological Survey Report (ASR) in Attachment B. Consistent with SPR CUL-4, archaeological surveys (cursory, general, and complete surveys) were conducted by archaeologically trained resource professionals for the identified and planned treatment Units including approximately 453 acres of dozer/control lines and 545 acres of burn units. High probability areas were determined and received a higher degree of survey intensity. Survey coverage intensity and results are disclosed in the Archaeological Survey Report (ASR). Additionally, the project area has been subject to several previous cultural resource surveys conducted within and adjacent to it, as documented in the ASR. Of these efforts, four archaeological investigations occurred within or adjacent to the currently planned treatment units. The surveys identified no prehistoric resources within the treatment units and documented one previously recorded historic resource (Wildberger Orchard) within the treatment unit. Three additional previously recorded historic sites are located outside of, but adjacent to, the project area. Consistent with SPR CUL-7, the previously recorded historic-period resource, Wildberger Orchard, will be protected mainly through avoidance. A small portion of an existing control/dozer line intersects the site boundary at the northeastern edge of the site where the control line meets an existing seasonal road that traverses downslope through the site. This existing seasonal road and control/dozer line will likely be needed for ingress and egress of heavy equipment and vehicles associated with the fuels reduction grant project. All vehicles and equipment shall be restricted to ingress/egress along the existing dirt road/control line within the site boundaries. Vegetat ion removal along the existing road and control/dozer line shall consist of ONLY what is required to maintain safe and efficient access to and from the project area. A CAL FIRE Archaeologist or a CAL FIRE Forester with current CAL FIRE Certified Archaeological Surveyor training shall be onsite the day that equipment and vehicles are accessing the project area through t he Wildberger Orchard site. Consistent with SPR CUL-8, a CAL FIRE Archaeologist or a CAL FIRE Forester with current CAL FIRE Certified Archaeological Surveyor training shall train all crew members and contractors implementing treatment activities on the protection of sensitive archaeological, historical, or tribal cultural resources. Workers will be trained to halt work if archaeological resources are encountered on a treatment site and the treatment method consists of physical disturbance of land surfaces. IMPACT CUL-1 Proposed treatment activities within the Treatment Units include mechanical treatments, manual treatments, and prescribed burning, which could damage historical resources. Although the NWIC records search revealed one historic feature , this has not been evaluated for eligibility for listing in the California Register of Historical Resources (CRHR). Therefore, it is not known whether this site is considered to be a resource under CEQA. Nevertheless, historic features (i.e., homestead sites, refuse piles) over 50 years old that have not been evaluated for historical significance and are present in the treatment areas will be avoided pursuant to SPR CUL-7. The potential for these treatment activities to result in disturbance, damage, or destruction of built-environment structures that have not yet been evaluated for historical significance was examined in the PEIR. This impact is within the scope of the PEIR, because treatment activities and the intensity of ground disturbance of the treatment projec t are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the treatment area, the potential to encounter built -environment structures that have not yet been evaluated for historical significance in areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the potential impact to historical resources is also the same, as described above. SPRs applicable to this impact are CUL-1, CUL-7, and CUL-8. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT CUL-2 Vegetation treatment would include mechanical treatments using heavy equipment that could churn up the surface of the ground during treatment as vegetation is removed; this may result in damage to known or previously unknown archaeological resources. The NWIC records search revealed one historical site within the Treatment Units/PIZ. The NWIC records search revealed no prehistoric resources within the Treatment Units/PIZ. Surveys have been conducted prior to treatment pursuant to SPR CUL-4 to identify any previously unrecorded archeological resources and identified resources will be avoided according to the provisions of SPR CUL-5. The potential for these treatment activities to result in inadvertent discovery and subsequent damage of unique archaeological resources or subsurface historical resources during vegetation treatment was examined in the PEIR. This impact was identified as significant and unavoidable in the PEIR because of the large geographic extent of the treatable landscape and the possibility Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 28 that there could be some rare instances where inadvertent damage of unknown resources may be extensive. For the Ukiah West Hills Vegetation Treatment Units, SPRs and Mitigation Measure CUL-2 would require identification and protection of resources, and it is reasonably expected that implementation of these measures would avoid a substantial adverse change in the significance of any unique archaeological resources or subsurface historical resources. Therefore, this impact would be less than significant. This impact is within the scope of the PEIR, because treatment activities and intensity of ground disturbance of the treatment project are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the treatment area, the potential for discovery of archaeological resources is essentially the same within and outside the treatable landscape; therefore, the potential impact to unique archaeological resources or subsurface historical resources is also the same, as described above. SPRs applicable to this treatment include CUL-1 through CUL-8. Mitigation Measure CUL-2 would also apply to this treatment to protect any inadvertent discovery. If any prehistoric or historic-era subsurface archaeological features or deposits, including locally darkened soil (“midden”), that could conceal cultural deposits, are discovered during ground - disturbing activities, all ground-disturbing activity within 100 feet of the resources will be halted and a qualified archaeologist will work with the project proponent to develop a site record and protection measures. Local tribes will be contacted and consulted regarding protection measures. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT CUL-3 Native American contacts in Mendocino County were contacted via letter and email on February 1, 2024. The Native American contact list was obtained from the CAL FIRE Native American Contact List (revised September 20, 2023) published on their website. No responses were received from any Native American tribes as of May 23, 2025. The potential for the proposed treatment activities to cause a substantial adverse change in the significance of a tribal cultural resource during implementation of vegetation treatment was examined in the PEIR. This impact is within the scope of the PEIR, because the intensity of groun d disturbance of the treatment project is consistent with that analyzed in the PEIR. As explained in the PEIR, while tribal cultural resources may be identified within the treatable landscape during development of later treatment projects, implementation of SPRs would avoid any substantial adverse change to any tribal cultural resource. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the tribal cultural affiliations present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the potential impact to tribal cultura l resources is also the same, as described above. SPRs applicable to this treatment include CUL -1 through CUL-8. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT CUL-4 Vegetation treatment activities would include mechanical treatments using heavy equipment; these treatments may use skid steers, excavators, dozers, and masticators, which could uncover human remains. The NWIC records search did not reveal any burials or sites containing human remains. The potential for treatment activities to uncover human remains was examined in the PEIR. This impact is within the scope of the PEIR, because the treatment activities and intensity of ground disturbance a re consistent with those analyzed in the PEIR. Additionally, consistent with the PEIR, the project would co mply with California Health and Safety Code Section 7050.5 and PRC Section 5097 in the event of a discovery. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent p resented in the PEIR. However, within the boundary of the treatment area, the potential for uncovering human remains during implementation of the treatment project is essentially the same within and outside the treatable landscape and treatment activities; therefore, the impact related to disturbance of human remains is also the same, as described above. No SPRs or MMs are applicable to this impact. This determination is consistent with the PEIR and would not constitute a substantially more severe significa nt impact than what was covered in the PEIR. NEW ARCHAEOLOGICAL, HISTORICAL & TRIBAL CULTURAL RESOURCE IMPACTS The proposed treatment is consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.5.1, “Environmental Setting,” and Section 3.5.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the treatment area, the existing Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 29 environmental and regulatory conditions pertinent to archaeological, historical, or tribal cultural resources that are presen t in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the im pacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact related to archaeological, historical, or tribal cultural resources would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.5.1 Biological Resources Discussion In accordance with SPR BIO-1, a qualified botanist conducted a comprehensive data review of biological resources specific to the project, including habitat and vegetation types, special-status plants, special-status wildlife, and sensitive habitats (e.g., sensitive natural communities and wetlands) that have the potential to occur in the treatment areas. The identification of habitat and vegetation types within these treatment areas was accomplished through both vegetation mapping and on-site assessments. The combined acreage of the treatment areas totals approximately 1,350 acres. An agency (in this case only CDFW) notification letter was mailed out on February 19, 2024, as part of the compliance for PRC §4123 communications. A response from CDFW was received on February 28, 2024, and no comments were noted. A revised letter was emailed to CDFW on May 20, 2025, and a response received the same day with questions/comments. Through email Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 32 correspondence, the questions were clarified and incorporated into the project design. A list of special-status plant and wildlife species with the potential to occur in the project area was compiled by completing a review of the California Department of Fish and Wildlife's (CDFW) California Natural Diversity Database (CNDDB) and California Native Plant Society (CNPS) Rare Plant Inventory database records for the 12 U.S. Geological Survey (USGS) quadrangles (referred to as quads) containing and surrounding the project area (CDFW 2024a; CNPS 2024a), the U.S. Fish and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) tool (USFWS 2024); and Appendix BIO-3 (Table 9b, Table 10a) in the PEIR for special-status plants and wildlife that could occur in the Northern California Coast (263A) and Coast Ranges (M261B) Ecological Sections. The search parameters encompassed the following quads: Ukiah, Orrs Springs, Elledge Peak, Purdys Gardens, Potter Valley, Redwood Valley, Laughlin Range, Greenough Ridge, Bailey Ridge, Boonville, Cow Mountain, and Philo (Figure 4.5-1 CNDDB Map). A list of sensitive natural communities with the potential to occur in the project area (see Table 4.5-2) was compiled by completing a CNDDB search of the quads (CDFW 2024a), reviewing Tables 3.6-16 and 3.6-18 in the PEIR for sensitive natural communities that could occur in the Northern California Coast and Coast Ranges Ecological Sections in the habitat types mapped in the project area, and based on professional experience in similar landscapes of Mendocino County. FIELD SURVEYS NCRM, Inc. biologists conducted reconnaissance surveys on 6/30/22, 7/21/22, 7/26/22, 8/5/22, 8/25/22, 4/5/23, 4/28/23, 5/12/23, 6/26/23, 10/3/2023, 4/18/24, 6/20/24, 7/8/42, 8/9/24, 5/12/25 to identify and document sensitive resources (i.e., special-status plant species, sensitive natural communities) and to assess the suitability of habitat in the treatment areas for special-status plant and wildlife species. These surveys were conducted for the Treatment Units in three different coverage levels for both plant and wildlife species: cursory, complete, and none (Figure 4.5-2) and prioritized areas in habitats that may support special status species and where ground-disturbing activities may occur (i.e., dozer lines). Surveys were conducted throughout the fuel breaks along the eastern boundary (except where landowner permission was not granted), in the southern pocket of the project area, and in some areas on the eastern boundary of the project . Vegetation communities and soil characteristics were identified, and incidental wildlife observations were recorded. Based on the implementation of SPR BIO-1, a complete list of all special-status species and habitats with the potential to occur in the vicinity of the proposed project was assembled (Table 4.5-1). Twenty-four special-status plant species, 1 sensitive habitat, and 14 special-status wildlife were determined to have the potential to occur in the treatment areas (Table 4.5 -1). Species are discussed in detail under Impact BIO-1 (special-status plants) and Impact BIO-2 (special-status wildlife), and sensitive habitats are discussed under Impact BIO-3. GENERAL HABITAT DISCUSSION Prescribed burn treatments mimic natural disturbance and may offer benefits for wildlife, such as promoting herbaceous plant growth and diversity. Following a prescribed burn, abundant growth of forbs, legumes, and native grasses serve as vital sources of food and cover for diverse wildlife populations. In chaparral ecosystems, like the one found within the Ukiah West Hills project area, the deep-rooted flora plays a crucial role in stabilizing slopes and in general wildlife health. Fire is an integral component of the life cycle of chaparral plant communities, necessitating periodic burning to rejuvenate these ecosystems. As unburned plants age, the accumulation of dead material increases, reaching an estimated 30-50% within the project area. In cases where chaparral plants are uniformly mature and widespread, wildfires tend to be stand replacing extensive and highly destructive. The deliberate burning of vegetation stands to benefit wildlife species that rely on younger vegetation stages. While certain wildlife species thrive in these younger stages, others, dependent on mature chaparral or dense woodland understory, may be adversely affected by such transformations. Overall, the impact is not deemed significant due to the adaptability of many species and the variation in vegetation burn intensities, which are influenced by factors such as aspect, slope percentage, a nd slope position. This results in a mosaic effect, contributing to a wider range of habitats that can support a diverse array of wildlife. Chaparral species regenerate through both sprouting and reseeding processes. Fire eliminates shading that would hinder seedling success and reduces allelopathic germination inhibitors present in decaying organic material and soil. Additionally, combustion byproducts can induce germination, with smoke acting as a crucial chemical st imulant, as observed in Emmenanthe penduliflora, a California chaparral annual (Keeley and Fotheringham 1998). The decadent grass and shrub cover throughout the Ukiah West Hills project area corresponds with the loss of sub-dominant and herbaceous habitat essential for sustaining specific wildlife species. By removing this cover and reducing ground litter through moderate surface fire, dormant seed-based herbaceous species can germinate and thrive, given adequate light and moisture. The use of low-intensity prescribed fires also promotes nutrient cycling and contributes to the restoration of natural Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 33 vegetative seral stages and fuel levels. Eliminating unnatural accumulations of dead and downed vegetative debris reduces the intensity of wildfires during the summer months. Winter burning in chaparral stands does not contribute to the maintenance or establishment of forbs and nonsprouting shrubs. To mitigate this, strategic ignition/burnout is employed to create a mosaic pattern of burned and unburned areas, thereby ensuring a seed source for the burned regions. This mosaic pattern enhances the edge effect, increases plant diversity, and aids in restoring plant and wildlife habitat that is threatened by dense shrub growth. Vegetation types in the vicinity of the project area (Figure 4.5-3, Vegetation Cover Types Map) encompass grasslands, chamise chaparral, manzanita chaparral, mixed hardwood forest, and Douglas-fir – hardwood forest. The coastal sage scrub community type, addressed in SPR BIO-5 does not exist in the project area. Chaparral coverage varies from nearly continuous to sparse, with grassy openings and areas featuring a mixture of hardwood tree species and grasses. The chamise component ranges from pure stands to a 50/50 mix with ceanothus, manzanita, and other chaparral species along with minor amounts of herbaceous vegetation. The application of prescribed fire within this project will be confined to grassland, chamise, and mixed chaparral fuel types. ANNUAL GRASSLAND There are areas of grassland intermixed throughout the project area. Species include introduced and native annual grasses suc h as brome (Bromus spp.), bluegrass (Poa spp.), wild oats (Avena spp.), fescue (Vulpia spp.), dogtail (Cynosurus spp.), barley (Hordeum murinum), needlegrass (Nassella spp.), and oatgrass (Danthonia spp.). Additionally, Oregon white oak (Quercus garryana) may be present adjacent to grasslands. CHAMISE CHAPARRAL Chamise chaparral is commonly found on south-facing, xeric slopes within the project area. The root crown of chamise (Adenostoma fasciculatum) sprouts vigorously following ground disturbances, such as intense fires. Chaparral species such as wedgeleaf ceanothus (Ceanothus cuneatus), shrub canyon live oak (Quercus chrysolepis subsp. nana), and manzanitas (Arctostaphylos spp.) may may occur on less xeric microsites, such as north-facing slopes or canyon drainages, where slightly more moisture is available. MIXED CHAPARRAL Most of the proposed project area and burn units are composed of mixed chaparral. Present species include varying mixtures of chamise (Adenostoma fasciculatum), wedgeleaf ceanothus (Ceanothus cuneatus), deerbrush (C. integerrimus), common and whiteleaf manzanita (Arctostaphylos manzanita, A. viscida), birchleaf mountain mahogany (Cercocarpus betuloides), and toyon (Heteromeles arbutifolia). Hardwoods that are present, interspersed with areas of chaparral, include canyon live oak (Quercus chrysolepsis), dwarf interior live oak (Quercus wislezinii subsp. frutences), California scrub oak (Quercus berberidifolia), California buckeye (Aesculus californica), bigleaf maple (Acer macrophyllum), California bay (Umbellularia californica), and Pacific madrone (Arbutus menziesi). MIXED HARDWOOD FOREST / DOUGLAS -FIR - HARDWOOD FOREST Areas of mixed hardwoods and Douglas-fir forest are present on north-facing slopes and along drainages in the project area. Hardwoods typically include tanoak (Lithocarpus densiflorus) and Pacific madrone (Arbutus menziesi). Douglas-fir (Pseudotsuga menziesii), pine (Pinus spp.), and redwood (Sequoia sempervirens) are the main conifer species present. No late- seral stage forests are present within the project area. ECOREGIONS The PIZ encompasses two distinct ecoregions. The predominant ecoregion within the area is the Outer North Coast Ranges, characterized by high rainfall and mixed evergreen and hardwood forests including Douglas-fir, tanoak, Oregon white oak, and some needlegrass grasslands. Some redwood patches were observed in the project area. Mountain peaks in this region are lower in elevation than those in the High North Coast Ranges ecoregion to the east. Soil temperature regimes are predominantly mesic and soil moisture regimes are xeric. Landslides occur frequently in this region, and high sediment loads occur in streams and rivers. By the end of the summer season, all but the larger streams have typically dried up. Moving southward, the landscape gradually transitions into the Sonoma-Mendocino Mixed Forest ecoregion. In this region the dominant feature is a mixed hardwood forest, including tanoak, black oak, madrone, Oregon white oak, Douglas -fir, with only Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 34 a few small pockets of redwoods. Annual grasslands and chaparral also occur in the mosaic. The geological composition comprises Tertiary sandstone and shale, alongside some Cretaceous and Jurassic Franciscan Complex metasedimentary rocks. Most streams in this area flow eastward, ultimately joining the Russian River (Griffith et al. 2016). Notably, the Napa-Sonoma-Russian River Valley region does not directly intersect with the project area but does border the lower foothills to the east. This region is characterized by its lower, flatter terrain, higher population density, and greater presence of cropland, vineyards, and orchards compared to its surroundings. The part of this region closest to the PIZ experiences less maritime influence and fog compared to valleys further south. Predominantly, Quaternary alluvium covers extensive portions of the area, with occasional pockets of older, loosely consolidated sedimentary material.

Nests along coast on sequestered islets, usually on ground with sloping surface, or in tall trees along lake margins. No potential to occur within the project area despite being found statewide as the water sources on the project area are too small to support this species.

No potential to occur as the range of this DPS includes Redwood Creek, the Mad River, the Mattole River (Humboldt and Mendocino Counties), and parts of the Eel River watershed including the Middle Fork Eel River and the Van Duzen River in Mendocino County. Osprey Pandion haliaetus – – G5, S4 | CDF | CWL | ILC Associated strictly with large, fish-bearing waters, including rivers, lakes, bays, estuaries, and surf zones, primarily in ponderosa pine through mixed conifer habitats. Preys mostly on fish. Large nests built in treetops within 15 miles of a good fish-producing body of water. Not likely to occur despite being found statewide. Project area does not support suitable habitat of large trees for perching or nesting. Fisher Pekania pennanti – – G5, S2S3 | BLM | CSSC | ILC | USFS Intermediate to large-tree stages of coniferous forests and deciduous-riparian areas with high percent canopy closure. Uses cavities, snags, logs and rocky areas for cover and denning. Needs large areas of mature, dense forest.

Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 44 Species Listing Status1 Federal Listing Status1 State Other Listing Status1 Habitat Potential for Occurrence Northern spotted owl Strix occidentalis caurina Threatened Threatened G3TNRQ, S2S3 | BLM | CSSC | USFS Habitat consists of primarily of old growth forest. Generally, prefers older, complex forests with a high canopy closure for nesting and roosting. Structurally, high-quality habitat includes a multilayered, multispecies canopy, large conifer overstory trees, shade-tolerant understory conifers or hardwoods, moderate to high canopy closure, live coniferous trees with deformities (e.g., cavities, broken tops, mistletoe infections), large snags, and large logs and other woody debris on the forest floor. Not likely to occur due to the lack of contiguous complex conifer stands with complex characteristics preferred by NSO in the project area and did not appear in CNDDB search. Neither enough acreage of suitable nesting nor foraging habitat is present. Portions of the project area are adjacent to forest habitat that may provide some habitat. There is one known spotted owl Activity Center (MEN629) located two miles northwest of the project area. Low intensity burns proposed by the project will not result in any existing NSO habitat modification. In addition, treatment activities will not impact the existing habitat function for potential future use by the NSO, as proposed activities would not result in the removal of trees or snags greater than 12 inches DBH and would retain canopy cover at 60% or greater within the forest habitat. American badger Taxidea taxus – – G5, S3 - CSSC | ILC Most abundant in drier open stages of most shrub, forest, and herbaceous habitats, with friable soils.

In accordance with SPR BIO-1, a qualified botanist conducted a comprehensive data review of biological resources specific to the project wherein thirteen special-status plant species ‘may occur’, three species are ‘likely to occur’, one was found to be ‘present within the project area’, twelve not likely to occur, and four with no potential to occur as described in Table 4.5-1: Potential for Special-Status Plant & Wildlife Species to Occur in the Treatment Areas. Pursuant to SPR BIO-7, special-status plant habitats where impacts cannot be avoided by a treatment must have protocol-level surveys conducted prior to implementation of manual, mechanical, or prescribed burning treatment s. If special-status plant species are observed during SPR BIO-7, Mitigation Measure BIO-1a for listed special-status plants under California Endangered Species Act (CESA) and federal Endangered Species Act (ESA), and Mitigation Measure BIO -1b for other non- listed special-status will be implemented SPR BIO-7 applies to all treatment activities. Surveys would not be required for special-status plants not listed under the CESA or ESA if the target special-status plant species is an herbaceous annual species, stump-sprouting species, or geophyte species, and the specific treatments may be carried out during the dormant season for that species or when the species has completed its annual life cycle, provided the treatment would not alter habitat in a way that would make it unsuitable for the special-status plants to reestablish following treatment, or destroy seedbanks, stumps, or roots, rhizomes, bulbs and other underground parts of special -status plants. If it is infeasible to conduct treatments during the dormant season, focused surveys will be conducted in those areas where ground- disturbing activities (i.e., dozer line) may occur. Seven of the thirteen special-status plant species that may occur within the project area are herbaceous annual species, geophytes, mosses, or lichen (denoted with asterisks in Table 4.5-1). Impacts on these species would be avoided by implementing non-ground-disturbing treatment activities (e.g., manual treatment activities) during the dormant season (i.e., when the plant has no aboveground parts), which would generally occur during the winter. Ground-disturbing treatment activities (e.g., mechanical treatments, construction of control lines for broadcast burning) may result in impacts on these plant species even when dormant and would not be conducted without prior implementation of SPR BIO-7. If non-ground-disturbing treatments cannot be completed in the dormant season and would be implemented during the growing period of these annual and geophyte species, protocol surveys (per SPR BIO-7) and avoidance of any identified plants (per BIO-1b) must be implemented, as described below. The remaining three specia l-status plant species that have the potential to occur within the project area are non-geophytic perennial species, which the qualified botanist has determined will benefit from project treatment activities, hence, protocol-level surveys under SPR BIO-7 would not be necessary to identify them before implementing treatment activities regardless of the timing of treatments. Where special-status plants are identified during protocol-level surveys, MM BIO-1a or BIO-1b, depending on the species status, a no-disturbance buffer of at least 50 feet will be established around the area occupied by the species within which prescribed fire, and manual and mechanical treatment would not occur unless a qualified RPF or botanist determines, based on substantial evidence, that the species would not be harmed or would benefit from treatment in the occupied habitat area. If treatments are determined to be beneficial and would be implemented in areas occupied by special -status plants, under the specific conditions described in MM BIO-1a for listed special-status and MM BIO-1b for non-listed special-status plants, additional impact minimization and avoidance measures or design alternatives to reduce impacts may be identified. A qualified RPF or botanist will evaluate the appropriate treatment design and frequency to maintain habitat function for the special -status plants. One special-status plant species – Raiche's manzanita – has been identified during the reconnaissance survey and is known to occur within the project impact zone (see Figure 4.5-2). Habitat information for this species can be found in Table 4.5-1. Impacts to this species’ habitat will be avoided through the implementation of MM BIO-1b. This information is to be used during Biological Resource Training for Workers, per SPR BIO-2. The potential for treatment activities to result in adverse effects on special -status plants was examined in the PEIR. This impact on special-status plants is within the scope of the PEIR, because, within the boundary of the project area, habitat characteristics are essentially the same within and outside the treatable landscape (e.g., no resource is affected on land outside the treata ble landscape that would not also be similarly affected within the treatable landscape), and the treatment activities and intensity of disturbance as a result of implementing treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the p otential impact on special-status plants is also the same, as described above. Biological resource SPRs that apply to project impacts under Impact BIO-1 are SPRs BIO-1, SPR BIO-2, SPR BIO-6, SPR BIO-7, SPR BIO-9, SPR GEO-1, SPR GEO-3, SPR GEO- 4, SPR GEO-5, SPR GEO-7, SPR HYD-4, and SPR HYD-5. This determination is consistent with the PEIR and would not Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 46 constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT BIO-2 Treatment activities of prescribed burning, manual treatments (i.e., handline construction), and mechanical treatments (i.e., control line construction or maintenance) could result in direct or indirect adverse effects on special -status wildlife species either directly or through habitat modifications. The proposed actions associated with this project are within the scope of treatment activities analyzed in the PEIR. The SPRs and MMs are designed to identify habitat, consider critical life-history periods for special-status species, and avoid significant adverse impacts to special-status wildlife species within treatment areas. These SPRs and MMs will be followed during project planning activities and implementation and will result in less than significant impacts. Mitigation Measures BIO-2a and 2b will be employed to avoid mortality, injury, or disturbance to special status wildlife species by: • Avoiding treatment or disturbance activities within occupied habitats. • Conducting treatment and/or disturbance activities outside the critical life history period (e.g., hibernation, denning, rearing, breeding seasons, etc.). • Designing treatments to maintain habitat function and essential structural elements (e.g., cavities, nests, dens, resting structures, etc.) associated with a critical life-history periods (identified by a qualified RPF or other qualified personnel). • Establishing a no-operations disturbance buffer surrounding currently occupied sites. Buffer size determined by established protocols and trustee agency guidance, or where relevant, by a qualified RPF or other qualified personnel. • If a northern spotted owl is detected at any point during the life of the project, a no-disturbance buffer of 0.25- mile will be established around the detection and no treatment activities would be allowed within the buffer. In accordance with SPR BIO-10, the qualified RPF determined that focused or protocol surveys for all special -status species with potential to occur in the treatment area are not required, depending on the timing of the annual burn prescription . It is anticipated that the treatment activities will not lead to loss of special -status wildlife that would substantially reduce the number or restrict the range, or to degradation of occupied habitat. During pre -treatment walk-through of the annual burn area by the RPF, within 14 days prior to any project preparation, any observations of special -status wildlife and nursery sites will be recorded and considered for a no-disturbance buffer (50 to 150 feet based on the standard for that species). California Giant Salamander and Red-Bellied Newt California giant salamander and red-bellied newt have potential to occur in some of the treatment areas (Table 4.5-1; see Figure 4.5-4 Wetlands and Riparian Areas). Habitat potentially suitable for these species includes perennial and intermittent streams and associated uplands, including forest habitat under leaf litter and logs. California giant salamanders are typically found within approximately 165 feet of stream habitat. Red-bellied newts spend dry summer months in moist habitats (e.g., under woody debris, rocks, animal burrows), which, based on dry conditions in the treatment areas observed during the September 14 and 15 reconnaissance surveys, would limit the species to areas relatively close to streams, ponds, and seeps (i.e., approximately 100 feet). WLPZs ranging from 50 to 150 feet adjacent to all Class I and Class II streams within the treatment areas would be implemented per SPR HYD-4, also including its project-specific refinement to include the implementation of no-disturbance buffers around all ponds (including ponds on adjacent private property where the buffer extends into a treatment area). The potential for treatment activities and maintenance treatments to result in adverse effects on special -status amphibians was examined in the PEIR. Habitat function for California giant salamander and red-bellied newt would be maintained because treatment activities and maintenance treatments would not occur within aquatic habitat, and treatments within WLPZs adjacent to treatment areas would be limited pursuant to SPR HYD-4 (e.g., no mechanical treatment, retention of at least 75 percent surface cover, no treatment within 50 to 150 feet of ponds). The potential for treatment activities to result in adverse effects on special -status amphibians was examined in the PEIR. Pursuant to SPR HYD-4, a WLPZ width of 50 to 150 feet adjacent to all Class I and II streams and lakes will be implemented for watercourse protection. Prior to treatment activities, a qualified RPF or biologist will survey the treatment area to identify and map streams and wet areas. Habitat function for the southern torrent salamander and the red-bellied newt would be maintained because pursuant to SPR HYD-4, treatments within stream WLPZs in and adjacent to the treatment area would be limited. In addition, the largest downed logs (up to three logs per acre) would be retained within the treatment areas. Ignitions will not occur in aquatic habitat and in watercourses supporting these species. Watercourse protection measures shall be adhered to at all times . This impact of the proposed project is consistent with the PEIR and would not constitute a substantially more severe significant impact than wha t was included in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 47 Foothill Yellow-Legged Frog Habitat potentially suitable for foothill yellow-legged frog includes perennial streams within treatment areas and associated uplands. Foothill yellow-legged frog is known to occur within upland habitat up to approximately 200 feet away (CDFW 2018b), but typically no more than 40 feet away, from aquatic habitat (Bourque 2008). WLPZs ranging from 50 to 150 feet adjacent to all Class I and Class II streams within the treatment areas would be implemented per SPR HYD-4, including its project-specific refinement to include the implementation of no -disturbance buffers around all ponds (including ponds on adjacent private property where the buffer extends into a treatment area). However, these measures may not result in fu ll avoidance of foothill yellow-legged frogs if frogs are present further than 150 feet from stream habitat, or if manual activities implemented within the WLPZ resulted in injury or mortality of this species. If a foothill yellow-legged frog is found during treatments, it will receive a 50-ft buffer and be allowed to leave the project on its own. Per SPR BIO-1, to fully avoid habitat potentially suitable for foothill yellow-legged frog, a 50 to 150-foot no-disturbance buffer would be implemented prior to commencement of treatment activities by flagging along perennial streams (Class I and Class II) adjacent to the treatment areas. Habitat function for foothill yellow-legged frogs would be maintained because treatment activities and maintenance treatments would not occur within aquatic habitat, and treatments within WLPZs adjacent to treatment areas would be limited pursuant to SPR HYD-4 (e.g., no mechanical treatment, retention of at least 75 percent surface cover, no treatment within 50 to 150 feet of ponds). The potential for treatment activities to result in adverse effects on special -status amphibians was examined in the PEIR. Pursuant to SPR HYD-4, a WLPZ width of 50 to 150 feet adjacent to all Class I and II streams and lakes will be implemented for watercourse protection. Prior to treatment activities, a qualified RPF or biologist will survey the treatment area to identify and map streams and wet areas. Habitat function for the foothill yellow-legged frogs would be maintained because pursuant to SPR HYD-4, treatments within stream WLPZs in and adjacent to the treatment area would be limited. In addition, the largest downed logs (up to three logs per acre) would be retained within the treatment areas. Ignitions will not occur in aquatic habitat and in watercourses supporting these species. Watercourse protection measures shall be adhered to at all times. Northwestern Pond Turtle Aquatic habitat potentially suitable for the northwestern pond turtle is present within ponds and streams in and adjacent to the treatment areas, and this species could use upland habitat within treatment areas in the vicinity of these features. WLPZs ranging from 50 to 150 feet adjacent to all Class I and Class II streams within the treatment areas would be implemented per SPR HYD-4, including its project-specific refinement to include the implementation of no- disturbance buffers around all ponds (including ponds on adjacent private property where the buffer extends into a treatment area). However, these measures may not avoid impacts on northwestern pond turtles, if turtles are present further than 150 feet from stream habitat or 50 to 150 feet from ponds, or if manual activities implemented within the WLPZ resulted in injury or mortality of this species. Northwestern pond turtles may be present within upland habitat up to approximately 1,500 feet from water. Thus, existing WLPZs and protective buffers would not fully prevent impacts on the species. SPR BIO-10 would apply, and focused visual encounter surveys for northwestern pond turtle would be conducted within upland habitat areas suitable for the species prior to ground-disturbing treatment activities (i.e., mechanical treatments) and prescribed burning. If northwestern pond turtles are identified during focused surveys, Mitigation Measure BIO-2b for this species would be implemented. Under MM BIO-2b, because the qualified RPF has determined that treatment activities would be beneficial to special-status pond turtles, no compensatory mitigation will be required. The benefit of prescribed burning on the upland habitat of northwestern pond turtle outweighs the cost of a severe, catastrophic wildfire that would destroy the woodland and grassland habitat in the project area. Substantial evidence exists that habitat function of woodland is reasonably expected to improve with implementation of the treatment. For grassland habitat, prescribed burns increase plant diversity and species richness, particularly of native plants. The removal of the thatch layer increases light penetration, soil temperature, and nutrient availability, supporting native endemic forbs which require light exposure to generate (DiTomaso and Johnson 2006). The northwestern pond turtle would benefit from treatment in the occupied upland habitat area even though some of the species may be killed, injured, or disturbed during treatment activities, and the proposed project approach would be an exception in MM BIO-2b (CalVTP PEIR Sec. 3.6-149). The benefit of prescribed burning on the upland habitat of western pond turtle outweighs the cost of a severe, catastrophic wildfire that would destroy the woodland and grassland habitat in the project area. Habitat function for northwestern pond turtle would be maintained because treatment activities and maintenance treatments would not occur within aquatic habitat, and pursuant to SPR HYD-4 no treatment would occur within 50 to 150 feet of ponds and treatments within stream WLPZs adjacent to treatment areas would be limited (e.g., no mechanical treatment, retention of at least 75 percent surface cover). Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 48 Special-Status Birds Five special-status bird species may occur within the treatment area: American peregrine falcon, grasshopper sparrow, purple martin, and great blue heron (Table 4.5-1). Treatment activities, including mechanical treatments, manual treatments, and prescribed burning conducted during the nesting bird season (February 1–August 31) could result in direct loss of active nests if trees or shrubs containing nests are removed or burned. For nests within vegetation that would not be removed, treatment activities including mechanical treatments, manual treatments, prescribed burning, and herbicide application, could result in disturbance to active nests from auditory and visual stimulus (e.g., heavy equipment, chain saws, vehicles, personnel) potentially resulting in abandonment and loss of eggs or chicks. Per SPR BIO-1, if it is determined that adverse effects on habitat suitable for nesting special-status birds can be clearly avoided by physically avoiding habitat suitable the species or conducting treatments outside of the season of sensitivity (i.e., nest ing bird season), then no mitigation would be required. Adverse effects on nesting special -status birds would be clearly avoided for treatments that would occur outside of the nesting bird season (February 1–August 31). If conducting some treatments outside of the nesting bird season is determined to be infeasible for certain treatments, then SPR BIO-12 to survey for active bird nests would apply, and nesting bird surveys for the four species would be conducted prior to implementation of treatment activities. In the event that a northern spotted owl is detected, at any point during the life of the project, a no-disturbance buffer of 0.25- mile will be established around the detection and no treatment activities would be allowed within the buffer. The buffer may be revised in consultation with CDFW. If no active bird nests are observed during nesting bird surveys per SPR BIO-10, then additional avoidance measures for these species would not be required. If active special -status bird nests are observed (i.e., presence of eggs and/or chicks) or determined to likely be present based on nesting bird behavior, then they shall be retained. The project proponent will implement a feasible strategy to avoid disturbance of active nests (typically 100-500-ft buffer for raptors, as determined by RPF or biologist based on site specific and species-specific factors, and 50ft for non-listed special status species) and no treatment activities would occur within this buffer until the chicks have fledged as determined by a qualified biologist. Habitat function for special-status birds would be maintained because treatment activities would not result in removal of trees (i.e., conifers, hardwoods) or snags greater than 12 inches DBH, which would be the most likely features to be used by these species due to the cover provided by larger trees and three to five snags would be retained per acre to provide wildlife habitat. Additionally, treatments within riparian habitat (which provides nesting habitat for the special-status bird species that may occur in the treatment areas) that is included within a WLPZ would be limited pursuant to SPR HYD-4 (e.g., no mechanical treatment, retention of at least 75 percent surface cover). Pursuant to Mitigation Measure BIO -2a, this determination for American peregrine falcon must be made by CAL FIRE in consultation with CDFW. Therefore, if Mitigation Measure BIO- 2a is required for treatment activities, CAL FIRE would contact CDFW to seek technical input on the determination that habitat function would be maintained for American peregrine falcon. Those non-listed special-status wildlife would benefit from treatment in the occupied habitat area even though some of the non -listed special-status wildlife may be killed, injured, or disturbed during treatment activities, and the proposed project approach would be an exception in MM BIO-2b (CalVTP PEIR Sec. 3.6-149). The benefit of prescribed burning on the habitat of these special-status birds outweighs the cost of a severe, stand-altering wildfire that would kill the forest and woodland habitat in the project area. Special-Status Fish Only one special-status fish species may occur within the treatment area: steelhead – Central California coast DPS (Table 4.5-1, refer to Figure 4.5-4). Per SPR BIO-1, if it is determined that adverse effects on special-status fish can be clearly avoided by physically avoiding habitat for these species, then mitigation would not be required. WLPZs ranging from 50 to 150 feet adjacent to all Class I a nd Class II streams within the treatment areas would be implemented per SPR HYD-4. Adverse effects on special-status fish would be clearly avoided through implementation of these SPRs and further mitigation would not be required. Habitat function for special-status fish would be maintained because treatment activities and maintenance treatments would not occur within aquatic habitat and treatments within WLPZs adjacent to treatment areas would be limited. Pursuant to SPR HYD-4 (e.g., no mechanical treatment, retention of at least 75 percent surface cover) WLPZs ranging from 50 to 150 feet adjacent to all Class I and II streams within the treatment areas will be implemented. At least 75 percent of surface cover will be retained. Equipment limitation zones (ELZs) will be designated adjacent to Class III and IV watercourses with required minimum widths per SPR HYD-4. A qualified RPF will describe the limitations of heavy equipment within the ELZ and will include additional protection measures where appropriate. Any exposure of soil from burning or soil disturbed in a watercourse Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 49 crossing of Class II, II, or III within a WLPZ shall be stabilized to the extent necessary to prevent the discharge of soil into watercourses that would adversely affect steelhead. American Badger Potentially suitable habitat for American badger is present within grassland and open woodlands in the treatment areas. Treatment activities, including mechanical treatments, could result in direct loss of active dens and potential loss of young. Treatment activities including manual treatments, prescribed burning, and herbicide application treatments are not expected to result in adverse effects on American badger dens due to badgers being primarily nocturnal and residing in dens during the day when operations would be implemented. In addition, these treatments would typically occur within habitats where American badger dens are unlikely to occur (e.g., forest habitat), and because personnel would conduct these activities on foot, and t he likelihood of a den being inadvertently crushed or otherwi se destroyed would be very low. If implementation of mechanical treatments in suitable habitat will occur during the American badger breeding season (between March 1 and August 31), focused surveys per SPR BIO-10 will occur or presence will be assumed. If individuals or dens are found within the treatment area or if presence is assumed, MM BIO-2b will be implementation to prevent adverse impacts. If a den is discovered during this critical period, operations shall cease within 100 feet, and CDFW will be consulted for additional avoidance measures, as appropriate. Habitat function for American badger would be maintained because habitat suitable for the species (i.e., grasslands, open woodlands) would be maintained and additional open woodland habitat would likely be restored through thinning and removal of ladder fuels. The use of prescribed fire is not considered to have an adverse effect on badger populations, as it promotes the healthy function and maintenance of oak woodland and grassland ecosystems. Additionally, potentially suitable habitat exists throughout the project area and all habitat suitable for American badger will not be treated at once. Western Bumble Bee Suitable habitat for the western bumble bee is potentially present within grassland and open woodlands in the treatment areas. Treatment activities, including mechanical treatments, prescribed burning, and herbicide treatments using UTVs could result in direct loss of individuals and even colonies. Habitat requirements for the western bumble bee are meadows and grasslands with abundant floral resources (Hatfield et. al. 2018). The project area contains habitat suitable for bumble bee nesting, overwintering, and floral resources. Potential impacts associated with treatment activities could include temporary removal of floral resources (especially invasive floral resources) or in trampling, crushing, or disturbing nesting or overwintering sites (e.g., woody debris). Because there is no seasonal timing that would prevent all potential impacts to Western bumble bee, SPR BIO-10 will be implemented prior to mechanical treatments in suitable habitat or presence will be assumed. SPR BIO-10 would also be required prior to prescribed burning or herbicide applications during the bumble bee flight season. If foraging individuals or nests are observed, or presence is assumed, MM BIO-2g will be implemented. Per MM BIO-2g, prescribed burning within occupied or suitable habitat for special-status bumble bees will occur from October through February to avoid the bumble bee flight season, when feasible. Operationally this may not be feasible, as prescribed burning requires a narrow range of climatic conditions to ensure control and to meet the project objectives. Additionally, treatment areas in occupied or suitable habitat will be divided into a sufficient number of treatment units such that the entirety of the habitat is not treated within the s ame year and treatments will be conducted in a patchy pattern to the extent feasible in occupied or suitable habitat, such that the entirety of the habitat is not burned or removed and untreated portions of occupied or suitable habitat are retained (e.g., f ire breaks will be aligned to allow for areas of unburned floral resources for special-status bumble bees within the treatment area). Herbicides will not be applied to flowering native plants within occupied or suitable habitat to the extent feasible during t he flight season (March through September). Lastly, if an active nest or overwintering queen is found, a 25-ft buffer will be utilized to prevent impacts. Prescribed burning is expected to have a positive effect on the richness and abundance of flowering plant species used by bee s by increasing plant diversity, particularly of native plants. The removal of the thatch layer increases light penetration, so il temperature, and nutrient availability, supporting native endemic forbs which require light exposure to generate (DiTomaso and Johnson 2006). Greater floral diversity can benefit bee populations by providing a more balanced and continuous source of nutrition. In addition, the overall long term habitat function for the western bumble bee would remain as prescribed burning, and mechanical and manual treatment activities would retain large snags and logs, which would be the most likely nesting features to be used by special-status bumble bees, as well as clearing away leaf litter and debris making it easier to excavate and establish nests in the soil, and suitable habitat for the bumble bees in the project area would not be treated at once. Areas of unburned habitat and floral resources will remain following prescribed burning as treatments are conducted in a mosaic pattern designed to retain habitat and suitable floral resources proximate to the treatment area. If herbicide application is necessary in suitable habitat to meet project objectives, application would be restricted to October through February to avoid Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 50 bumble bee flight season and blooming resources. Pursuant to MM BIO-2a, the final determination for habitat function maintenance will be made by the project proponent and the project proponent may seek technical input from CDFW on their proposed measures to avoid injury to or mortality of these species if found during pretreatment surveys or during operations. The PEIR concluded that impacts on special-status bumble bees would be potentially significant and unavoidable because it addressed the entirety of the treatable landscape across the state, so significant impacts cannot be ruled out. However, for this project, impacts would be less than significant and less severe than asserted in the PEIR due to the implementation of focused surveys in suitable habitat, implementation of MM BIO- 2g, and the expected net increase in floral (foraging) resources following treatments. Special-Status Bats Habitat potentially suitable for three special-status bat species—pallid bat, Townsend’s big-eared bat, and hoary bat—is present within forest habitat, rocky areas, and human-made structures (e.g., barns, bridges) in the treatment areas. Per SPR BIO-1, if it is determined that adverse effects on special-status bats can be clearly avoided by conducting treatments outside of the season of sensitivity (i.e., maternity season), then mitigation would not be required. Adverse effects on special-status bat maternity roosts would be clearly avoided if treatment activities are implemented outside of the bat maternity season (April 1–August 31; California Department of Transportation 2004). Treatment activities, including mechanical treatments, manual treatments, prescribed burning, and herbicide treatments using UTVs, conducted within habitat suitable for bats during the bat maternity season (April 1–August 31) could disturb active bat roosts from auditory and visual stimuli (e.g., heavy equipment, chain saws, vehicles, personnel) or smoke (e.g., prescribed burning) potentially resulting in abandonment of the roost and loss of young. Some herbicide treatments would be limited to ground-based methods, such as using a backpack sprayer or painting herbicide onto cut stems and would be conducted by crews of one to five people; thus, these treatments would not be expected to result in substantial disturbance to special -status bat roosts. During nesting bird surveys, per SPR BIO-12, surveys for maternal nesting bat roosts will also be conducted. If an active roost is observed, a no disturbance buffer of 100 feet would be established around the roost. Substantial evidence exists that habitat function of forest and woodland is reasonably expected to improve with implementatio n of the treatment. Historically, prior to fire suppression and logging, Douglas-fir-tanoak forests in the North Coast Range experienced fire return intervals between 4 to 6 years, which likely promoted open forests with greater cover of understory plant species. These non-listed special-status wildlife would benefit from treatment in the assumed occupied habitat area even though some of the non-listed special-status wildlife may be killed, injured, or disturbed during treatment activities, and the proposed project approach would utilize an exception described in MM BIO-2b (CalVTP PEIR Sec. 3.6-149). Furthermore, the short-term potential impacts of low intensity prescribed burning on these special -status bats outweigh the cost of a severe, stand-altering wildfire that would kill the forest and woodland habitat in the project area. Treatments will not result in impacts to special status species based on implementation of applicable SPRs (BIO-1, BIO-12). Habitat function for special-status bats would be maintained and, in some respects, improved. Treatment activities and maintenance treatments would not result in removal of living trees (i.e., conifers, hardwoods) greater than 1 2 inches DBH which would be the most likely features to be used by this species due to the cover provided by larger trees, and three to five snags would be retained per acre to provide wildlife habitat. Fuels treatments would reduce understory density and increase forest structural heterogeneity, which would improve foraging and movement conditions for bat species adapted to open and edge habitats. In addition, implementation of the treatment would reduce the likelihood of high-severity wildfire, thereby maintaining long-term availability of large trees and snags important for bat roosting habitat. Therefore, habitat function would be retained or enhanced consistent with Mitigation Measure BIO-2b. IMPACTS BIO-2 Conclusion The potential for treatment activities to result in adverse effects on special -status wildlife was examined in the PEIR. This proposed project’s impact on special-status wildlife is within the scope of the PEIR because the project consists of vegetation treatment activities (e.g., prescribed fire, mechanical thinning, and/or manual treatments) that are analyzed in the VTP PEIR. Treatment methods, equipment, treatment extents, and maintenance activities do not exceed the treatment descriptions, intensity, or geographic scale evaluated in the PEIR for biological resources. The project incorporates all applicable VTP biological SPRs and Mitigation Measures and habitat function for special-status wildlife species will be maintained through avoidance, minimization, and habitat retention measures. Potential temporary disturbances to wildlife during treatment activities are short-term and localized, as contemplated in the PEIR, and are mitigated through implementation of standard VTP avoidance and timing measures. Accordingly, the project would not result in new or substantially more severe impacts to special-status wildlife than those analyzed in the VTP PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 51 The project’s burn design practices will maintain or improve habitat function for special -status wildlife species, as treatment units will occupy a small percentage of the landscape and are dispersed over a large area. Unburned refugia are maintained close to treatment units, the burn prescription shall create a mosaic of burned and unburned habitat within treatment units, with a small percentage of the treatment units burned annually, and key habitat structures and locations shall be retained and pro vided mitigations where necessary. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landsc ape; therefore, the potential impact on special-status wildlife is also the same, as described above. Biological resource SPRs that apply to project impacts under Impact BIO-2 are SPR BIO-1 through SPR BIO-4, SPR BIO-8 through SPR BIO-11, SPR BIO- 12, SPR GEO-1, and SPR HYD-1, SPR HYD-3 through SPR HYD-5, and SPR HAZ-5 and SPR HAZ-6. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR with the addition of MMs BIO 1a & 1b, BIO-2a through BIO-2h and MMs BIO-3a through BIO-3c. IMPACT BIO-3 Initial vegetation treatments and subsequent maintenance treatments have the potential to result in direct or indirect advers e effects on sensitive habitats, including designated sensitive natural communities. Maintenance treatments would involve the same activities as initial treatments. While excessive retreatment could increase impacts, retreatment is required to control the establishment and spread of non-native grasses, consistent with the Writ of Mandate issued by the Superior Court of San Diego County on November 14, 2025 in California Chaparral Institute v. Board of Forestry and Fire Protection (Writ), and will be implemented in compliance with applicable Standard Project Requirements and Mitigation Measures to minimize impacts on sensitive vegetation. The potential for treatment activities adversely affect sensitive natural communities was evaluated in the CalVTP PEIR. Consistent with SPR BIO-3, CALVEG mapping and reconnaissance-level surveys conducted pursuant to SPR BIO-1 were used to identify sensitive natural communities within the treatment areas. Sensitive natural communities documented or with potential to occur in the treatment areas include chaparral (e.g., chamise and common manzanita), oak woodlands protected under the Oak Woodlands Conservation Act (Public Resources Code Section 21083.4), including canyon live oak, interior live oak, California black oak, and blue oak, redwood forests, and riparian habitats adjacent to streams. Grasslands mapped as annual brome may contain localized occurrences of sensitive grassland or serpentine-associated communities; however, due to the fine-scale heterogeneity and temporal variability of these habitats, they were not mapped as distinct vegetation type s. Chaparral Habitat Chaparral habitat (e.g., chamise chaparral and common manzanita chaparral) is present within the proposed treatment areas. Pursuant to the 2025 writ, the PEIR may not be used for CEQA compliance for proposed vegetation treatments in chaparral habitats unless the proposed treatments fall within specific, limited categories the Court determined to be severable from the writ’s prohibitions. The proposed project qualifies under these severable categories, including Wildland-Urban Interface (WUI) fuel reduction treatments and limited-width strategic fuel breaks, as defined by the writ. The proposed project is a critical wildfire safety project designed to protect the community of Ukiah by reducing wildfire hazards in the Wildland Urban Interface (WUI) and establishing and maintaining strategically located fuel breaks around the community. Chaparral treatments within WUI areas will be designed to avoid type conversion and maintain chaparral habitat structure and function to the extent feasible while achieving wildfire hazard reduction objectives. Fuel break treatments, are intended to strategically modify vegetation to reduce fire behavior and improve firefighter and community protection and therefore are not designed to retain chaparral habitat within the fuel break footprint. Fuel break widths will be limited to the minimum necessary and will not exceed 300 feet in width, and long-term maintenance of flammable non-native vegetation will be implemented to prevent unintended type conversion outside treated areas. Consistent with Public Resources Code section 4483 and SPR Bio-5, the treatments will not result in type conversion. Oak Woodlands and Redwood Forests CAL FIRE will, to the extent feasible, and consistent with project objectives, retain mature madrone, true oaks, redwood, big- leaf maple, native shrubs (e.g., gooseberry and snowberry) and other desirable species (e.g., California rose, native wildflowers) within the WUI and shaded fuel break treatment types. Various natural communities have evolved to depend on periodic fire, and as such, the project’s burn design practices will not result in loss or degradation of these sensitive natural communities. The low intensity burn prescription shall result in a partial removal of understory or groundcover vegetation and create a mosaic of burned and unburned habitat within treatment units. The proposed project will also lower the risks to natural communities associated with a larger, uncontrolled wildfire. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 52 Riparian Habitat Riparian habitat is present adjacent to streams in treatment areas. Under SPR HYD -4, WLPZs ranging from 50 to 150 feet would be established adjacent to all Class I and Class II streams for manual, mechanical, herbicide, and pile burning treatme nts, which would limit the extent of treatment activities within riparian habitat. While this SPR would reduce potential impacts on riparian habitat, the extent of riparian habitat within the treatment areas has not been mapped and riparian habitat may be present outside of the areas incorporated within WLPZs. As a result, prior to the implementation of treatment activities, SPR BIO-3 would need to be implemented to identify and map the extent of riparian habitat within the treatment areas. As required under SPR BIO-4, treatments in riparian habitats would retain at least 75 percent of the overstory and 50 percent of the understory canopy of native riparian vegetation and would largely be limited to removal of uncharacteristic fuel loads (e.g., dead or dying vegetation, invasive plants, encroaching uplands species). Additionally, prior to any treatments in riparian habitat subject to California Fish and Game Code 1602, CAL FIRE would notify CDFW when required, as explained in SPR BIO-4. Mitigation Measure BIO-3a For sensitive natural communities and oak woodlands not subject to the 2025 writ limitations, a qualified RPF or biologist would determine the natural fire regime, condition class, and fire return interval pursuant to Mitigation Measure BIO-3a. Initial and maintenance treatment activities within these applicable sensitive natural communities and oak woodlands would be designed to restore or maintain vegetation composition, structure, and ecological function consistent with their natural fire regimes, where doing so does not conflict with project objectives. If, for applicable sensitive natural communities or oak woodlands, habitat function would not be maintained through implementation of Mitigation Measure BIO-3a, then Mitigation Measure BIO-3b would apply, and unavoidable losses of those resources would be compensated through restoration or preservation of the affected vegetation types within or outside of th e treatment areas. The potential for treatment activities to result in adverse effects on sensitive habitats, as described above, was examined i n the PEIR. This impact on sensitive habitats is within the scope of the PEIR, because, within the boundary of the project area, habitat characteristics are essentially the same within and outside the treatable landscape (e.g., no resource is affected on l and outside the treatable landscape that would not also be similarly affected within the treatable landscape), and the treatment activities and intensity of disturbance as a result of implementing treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a chang e to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landsc ape; therefore, the potential impact on sensitive habitats is also the same, as described above. Biological resource SPRs that appl y to project impacts under Impact BIO-3 are SPR BIO-1 through SPR BIO-9, SPR GEO-1, SPR GEO-3, SPR GEO-4, SPR GEO- 5, SPR GEO-7, SPR HAZ-5, SPR HAZ-6, SPR HYD-4, and SPR HYD-5. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Potential adverse effects on chaparral habitat from treatment activities are expected to be short-term, localized, and consistent with the Writ and CalVTP PEIR analysis.

IMPACT BIO-4 Initial vegetation treatments and maintenance treatments will not result in direct or indirect adverse effects on state or federally protected wetlands as none have been identified in the project area. Based on review and survey of project-specific biological resources (SPR BIO-1), some portions of the treatment areas contain small segments of perennial, intermittent, and ephemeral streams that could be protected under federal and/or state government jurisdiction. Under SPR HYD-4, WLPZs ranging from 50 to 150 feet would be established adjacent to all Class I and Class II streams within the treatment areas, and WLPZs of sufficient size to avoid degradation of downstream beneficial uses of water would be established adjacent to all Class III streams within the treatment areas for manual, mechanical, herbicide, and pile burning treatments. Additionally, SPR HYD-4 will be refined to include the implementation of no-disturbance buffers of 50 to 150 feet around all ponds (including ponds on adjacent private property where the buffer extends into a treatment area). The establishment of WLPZs and buffers would result in the avoidance of all stream and pond habitat for manual, mechanical, herbicide, and pile-burning treatments. Broadcast burning would be implemented in all treatment areas and may occur within areas that contain seasonal freshwater emergent wetlands, springs, seeps, or stream habitats. Mitigation Measure BIO-4 would apply in treatment areas that contain state or federally protected wetlands where broadcast burning would occur. Under Mitigation Measure BIO-4, the boundary of jurisdictional features would be delineated, and broadcast burning may be implemented in wetland habitats if a qualified RPF or biologist determines that the wetland habitat does not support special-status plants (i.e., through implementation of SPR BIO-7) or wildlife species (i.e., through implementation of SPR BIO-10), that wetland habitat function would be maintained, and that the broadcast burn is within the normal fire return interval for the wetland vegetation types present. Additionally, no fire ignition (and associated use of accelerants) will occur within wetland habitat or within WLPZs surrounding wetland habitats. The potential for treatment activities to result in adverse effects on state or federally protected wetlands was examined in the PEIR. This impact on wetlands is within the scope of the PEIR, because, within the boundary of the project area, habitat Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 54 characteristics are essentially the same within and outside the treatable landscape (e.g., no resource is affected on land ou tside the treatable landscape that would not also be similarly affected within the treatable landscape), and the treatment activiti es and intensity of disturbance as a result of implementing treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the potential impact on wetlands is also the same, as described above. Biological resource SPRs that apply to proj ect impacts under Impact BIO-4 are SPR BIO-1, SPR BIO-2, SPR BIO-3, SPR BIO-4, SPR BIO-9, SPR GEO-1, SPR GEO-3, SPR GEO-4, SPR GEO- 5, SPR GEO-7, SPR HAZ-5, SPR HAZ-6, SPR HYD-1, SPR HYD-4, and SPR HYD-5. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT BIO-5 Initial vegetation treatments and maintenance treatments could result in direct or indirect adverse effects on wildlife movement corridors and nurseries because habitat suitable for wildlife is present in treatment areas. Potential impacts resulting from maintenance activities would be like those resulting from initial vegetation treatments because the same treatment activities are proposed. The potential for treatment activities to result in adverse effects on wildlife movement corridors and nurseries was examined in the PEIR. Portions of the treatment area may occur within landscape features that function as wildlife movement corridors, including streams and associated riparian areas. However, the proposed WUI and fuel break fuel -hazard reduction treatments are designed to reduce hazardous vegetation conditions while largely maintaining existing site conditions that facilitate wildlife movement. Implementation of these treatment activities would not result in substantial changes to corridor continuity, topography, or vegetation structure that would impede wildlife movement through the treatment areas. WUI and fuel break treatments would focus on reducing surface, ladder, and aerial fuels through thinning of small -diameter trees, removal of excessive standing dead vegetation, and reduction of dense understory vegetation where fuel loading contributes to elevated wildfire risk near developed areas and along strategic fuel break locations. Treatments would be selective and spatially limited, retaining larger trees and overall canopy connectivity to the extent feasible while achievin g fuel- reduction and fire-behavior-modification objectives. Any incidental effects on native vegetation structure would be secondary to the primary purpose of wildfire risk reduction, protection of communities, and maintenance of effective fuel break functio n. These treatments would not be expected to reduce the ability of wildlife to move through treated areas and may reduce the ris k of movement disruption by lowering the likelihood of high-severity wildfire that could otherwise result in large-scale habitat loss or corridor fragmentation. Additionally, no known wildlife nursery sites or evidence of nursery use, such as deer fawning habitat or potential rookery trees indicated by whitewash, were identified within treatment areas during implementation of SPR BIO-1. The potential for treatment activities to result in adverse effects on wildlife movement corridors and nurseries was examined in the PEIR. This impact is within the scope of the PEIR, because, within the boundary of the project area, habitat characteristics are essentially the same within and outside the treatable landscape (e.g., no resource is affected on land outside the treatable landscape that would not also be similarly affected within the treatable landscape), and the treatment activities and extent of expected disturbance as a result of implementing treatment activities are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the potential impact on wildlife movement corridors is also the same, as described above. Habitat function within treatment areas would be maintained because treatment activities, including maintenance treatments, would not result in removal of living trees (i.e., conifers, hardwoods) greater than 12 inches DBH and 3–5 snags would be retained per acre to provide wildlife habitat, which would promote connectivity. Additionally, WLPZs ranging from 50 to 150 feet would be implemented adjacent to all Class I and Class II streams in treatment areas, which could function as wildlife movement corridors, pursuant to SPR HYD-4. Biological resource SPRs that apply to project impacts under Impact BIO-5 are SPR BIO- 1, SPR BIO-4, SPR BIO-10, SPR BIO-11, and SPR HYD-1 and SPR HYD-4. Additionally, MM BIO-5 will mitigate any potential impacts as well. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT BIO-6 Initial vegetation treatments and maintenance treatments could result in direct or indirect adverse effects resulting in reduction of habitat or abundance of common wildlife, including nesting birds, because habitat suitable for these species is present Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 55 throughout treatment areas. Treatment activities, including mechanical treatments, manual treatments, prescribed burning, and herbicide application, conducted during the nesting bird season (February 15– August 15) could result in direct loss of active nests or disturbance to active nests from auditory and visual stimulus (e.g., heavy equipment, chain saws, vehicles, personne l) potentially resulting in abandonment and loss of eggs or chicks. The potential for treat ment activities, including maintenance treatments, to result in adverse effects on these resources was examined in the PEIR. SPR BIO-12 would apply, and for treatments implemented during the nesting bird season, a survey for common nesting birds will be conducted within the treatment area by a qualified RPF or biologist prior to treatment activities. If no active bird nests are observed during focused surveys, then additional avoidance measures would not be required. If active nests of common birds or raptors are observed during surveys, disturbance to the nests will be avoided by establishing an appropriate buffer around the nests, modifying treatments to avoid disturbance to the nests, or deferring treatment until the nests are no longer active as determined by a qualified RPF or biologist. Trees with visible raptor nests, whether occupied or not, will be retained and a 100-500-ft avoidance buffer, as determined by RPF or biologist based on site specific and species-specific factors, shall be implemented. The qualified RPF determined that common nesting bird populations occupying project habitat will benefit from treatment in those areas even if the common nesting birds may be killed, injured, or disturbed during treatment activities. The project’s burn design practices will maintain or improve habitat function for common nesting birds and raptors, as treatment units will occupy a small percentage of the landscape and are dispersed over a large area. Unburned refugia are maintained close to treatment units, the burn prescription shall create a mosaic of burned and unburned habitat within treatment areas, and key habitat structures and locations shall be retained and provided mitigations where necessary. As included in the CalVTP PEIR Sec. 3.6-126, implementation of avoidance strategies for common nesting birds does not preclude completing the prescribed burning treatment within the project -specific burn season (February through May), during which vegetation moisture, weather, wind, and other physical conditions are suitable. The potential for treatment activities to result in adverse effects on these resources was examined in the PEIR. The potentia l for adverse effects on common wildlife, including nesting birds, is within the scope of the PEIR, because, within the boundar y of the project area, habitat characteristics are essentially the same within and outside the treatable landscape (e.g., no resou rce is affected on land outside the treatable landscape that would not also be similarly affected within the treatable landscape), and the treatment activities and extent of expected disturbance as a result of implementing treatment activities are consistent with those analyzed in the PEIR. Biological resource SPRs that apply to project impacts under Impact BIO-6 are SPR BIO-1 through SPR BIO-4, and SPR BIO-12. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT BIO-7 The potential for treatment activities to result in conflicts with local policies or ordinances was examined in the PEIR. The project area is partially within the bounds of City of Ukiah and partially in unincorporated areas of Mendocino County. The land use planning in unincorporated areas Mendocino County is governed by the Mendocino County General Plan (Mendocino County 2009). A number of General Plan goals and policies specifically address the need to protect and preserve riparian and instream habitat values, to support fish populations, particularly native anadromous fish species such as Chinook salmon and steelhead. These include: • Policy RM-89: Conserve and enhance watercourses to protect habitat, fisheries, soil, and water quality. • Policy RM-90: Conserve and enhance streamside (riparian) vegetation through development design and standards. • Policy RM-91: Stream restoration and maintenance programs shall conserve riparian vegetation and the floodwater carrying capacity of river and stream channels. • Policy RM-92: Whenever possible, use riparian vegetation in conjunction with natural or appropriate structural materials to achieve a natural appearance. • Policy RM-93: Encourage public agencies and private property owners to protect fishery habitat and participate in fishery enhancement projects (including removal of barriers to fish passage) for coastal and inland waterways of Mendocino County. Applicable local ordinances relevant to biological resources within the City of Ukiah are the Tree Management Guidelines, the Municipal Code, and the Creek Maintenance Policies and Procedures. Section 6.9 of the Tree Management Guidelines, Hazardous Tree Management, applies to the parts of the project area classified as urban forest within the City of Ukiah and requires crews who remove or trim trees under emergency conditions to notify and provide an after-action review to the horticulturist or Director of Community Services (City of Ukiah, 2023). The Municipal Code addresses Tree Preservation and Planting Requirements in Section 9229, stating however that the removal of protected trees is exempt from the provisions this section under emergency situations (i.e., substantial, imminent risk or hazard to the public), if documentation of the emergency situation be provided to the Planning Department as soon as possible (Div. 9, Ch. 2; Article 18, 9229.1 – 9229.12). The project would fall under the purview of an emergency situation and this Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 56 document will be provided to the Planning Department. Several of the policies listed in the Creek Maintenance Policies and Procedures specifically address the need to protect and preserve riparian habitat. These include the following, which entail that creek maintenance activities shall not: • discharge pollutants or deposit new material into creeks. • result in modifications to the natural flow of water or result in a reduction of the water-carrying capacity. • result in increased flooding. • adversely affect the riparian corridor, including riparian vegetation and wildlife. The section encompassing vegetation management outlines procedures that ensure that storm water runoff is not obstructed, and that flooding does not occur. It is unlikely that any creeks within the project area would be disturbed by treatment activities and impacts would be less than significant. The submission of this document covers the Notification Requirements outlined in Appendix D of the Creek Maintenance Policies and Procedures. The potential for the proposed treatments to conflict with local policies is within the scope of the PEIR because vegetation treatment locations, types, and activities are consistent with those analyzed in the PEIR. In addition, all projects implemen ted under the CalVTP that are subject to local policies or ordinances would be required to comply with them, per SPR AD-3. This impact of the proposed project is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT BIO-8 This impact does not apply to the proposed project because the treatment areas are not within the plan area of any adopted ha bitat conservation plan or natural community conservation plan. Therefore, this impact does not apply to the proposed project. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW BIOLOGICAL RESOURCE IMPACTS The proposed treatment is consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined that they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.5.1, “Environmental Setting,” and Section 3.5.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to biological resources that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those considered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts not addressed in the PEIR. Therefore, no new impact related to biological resources would occur that is not covered in the PEIR.

These are typically marine sedimentary rocks that have accreted to the North American Continent and have been uplifted and heavily deformed by both accretion and the San Andreas Fault System. The primary rock types are graywacke sandstone, shale, chert, serpentine and blueschist (see Appendix F). These rock types are generally resistant to weathering but are jointed and foliated, creating large broken blocks (Sydnor 1991). Serpentine outcrops exist within the project area, particularly in the lower elevations north of Gibson Creek, near Low Gap Park (Sydnor 1991; Rubin 2022). The main rock unit within the project is the Lookout Peak graywacke formation, named by David M. Orchard in 1979 (Cretaceous-66-145 Ma). Mélange units border this unit to the north and south. The Maacama Fault, a right -lateral strike slip fault, is the northernmost segment of the Hayward fault subsystem to the San Andreas Fault (Larsen 2008) and runs through the Ukiah Valley to the east of the project area. The Lookout Peak Fault is located off the backside (west side) of the main t rending ridge in the project area, which contains Spanish Mountain and separates the Lookout Peak Formation with the Robinson Creek Mélange. The soils derived from this parent material includes many well drained, sandy loam soils, but depth to bedrock is shallow in many areas. The Soil Survey of Mendocino County, Eastern Part, and Trinity County, Southwestern Part (1991), specifies that prescribed burning in small to moderately sized blocks improves wildlife habitat, improves wildlife access and water production, and reduces th e risk of wildfire in these soil types. Large landslide features do exist within the project area, which can be identified in the lidar imagery in Figure 4.6-1, and their boundaries are mapped in Figure 4.6-2, estimated from previous mapping in the area. Serpentine outcrops are common in the greater Franciscan Complex, and in the area surrounding the PIZ, but are not as common in the specific project area. There are two recently mapped, relatively small outcroppings of serpentine within the lower elevations of the project area (Rubin 2022). The first and more substantial area is near Orrs Creek, north of Gibson Creek. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 58 Within this portion of the Project Implementation Zone (PIZ), a control line treatment area overlaps an existing linear featu re that may traverse serpentine soils near a mapped outcrop. Serpentine soil areas within the existing fuel break, which may hav e the potential to contain naturally occurring asbestos (NOA), would not be subject to additional ground disturbance beyond existing conditions, to the extent feasible. A second area within the PIZ is located along a ridge within the Spanish Creek Watershed, where Oak Knoll Road—also part of a control line treatment area—crosses a serpentine outcrop. While soils mapped by the Soil Conservation Service do not identify serpentine or NOA within the treatment areas, Mendocino County soil mapping indicates that portions of the ridge may consist of serpentine soils. As a result, it is possible that serpentine soils, and associated NOA, may be present within limited portions of the PIZ. Treatment activities in these areas would be limited to existing roads and control lines and would avoid new ground disturbance where serpentine soils are present or suspected. Implementation would comply with applicable CalVTP standard project requirements and best management practices designed to minimize soil disturbance and potential exposure to NOA. The locations of the serpentine outcrops and associated control lines are shown on Figure 4.6 -2, and mapped soil types are shown on Figure 4.6-3. A notification letter was emailed to Kevin Doherty (Senior Engineering Geologist) of the California Geological Survey -Forest and Watershed Geology Program on January 7, 2026, with project description, protection measures, and project maps. He was invited to share information or any concerns regarding potential impacts from geological hazards. As of February 19,, 2026, CGS recommends that if ground disturbing activities occur in areas identified as likely to contain naturally occur ring asbestos (NOA) that CAL FIRE contact Mendocino County AQMD to develop an Asbestos Dust Control Plan consistent with the requirements of SPR AQ-5. Topography The project area is located on a generally northeast facing slope, with multiple drainages that bisect the main ridge from east- west, including Gibson Creek, Doolin Creek and Spanish Creek. The faces of the drainages have north and south aspects. There is a trending ridgeline that is angled northwest, with sub ridges extending to the east. The highest elevation in the projec t area is around 2,800 feet, and the lowest is around 600 feet near Robinson Creek near the south portion of the project area. Most of the PIZ is steep- over 65%. Flatter areas within the project (>30%) are confined to the upper trending ridge and benches on the mid and lower slopes caused by old landslide features. Most of the control lines and skid trails used for vegetation treatment are located on ridges where the slopes are less than 50%. Some slopes within the treatment areas are over 50%. Soil Soils within the project area have been evaluated regarding soil type, erosion hazard, land suitability, permeability, and runoff rate. Please see Figure 4.6-3. Soils located in this project area include the Bearwallow-Hellman-Witherell complex, 30 to 50 percent slopes; Cummiskey gravelly loam, 30 to 75 percent slopes; the Feliz loam, 0 to 2 percent slopes; the Hopland -Maymen- Etsel complex, 50 to 75 percent slopes; Hopland-Wohly loams, 50 to 75 percent slopes and 30 to 50 percent slopes; Hopland- Woodin complex, 30 to 50 percent slopes; Hopland loam, 50 to 75 percent slopes; Kekawaka -Casabonne-Wohly complex, 30 to 50 percent slopes; Maymen-Etsel-Snook complex, 30 to 75 percent slopes; Pardaloe-Kekawaka-Casabonne complex, 50 to 75 percent slopes; Pinole gravelly loam, 2 to 8 percent slopes; Redvine sandy clay loam, 15 to 30 percent slopes; Squawrock - Witherell complex, 50 to 75 percent slopes; Witherell -Hopland-Squawrock complex, 50 to 75 percent slopes; the Yorktree- Yorkville loams, 15 to 30 percent slopes; and the Yorkville-Yorktree-Squawrock complex, 30 to 50 percent slopes. The ridges of the project area, where much of the treatment area s are located, generally contain the Hopland loam, Maymen- Etsel-Snook complex, and the Hopland-Maymen-Etsel complex soils. Mendocino County maps these soils as serpentine soils, but serpentine is not discussed in the soil descriptions. These soils are typically well drained but have slow permeability and lower capacities for water. Therefore, they are subject to rilling and gullying as their erosion hazard ratings are high and the runoff rates are rapid. Deep soil disturbance activities can cause land sliding and road failure (USDA 1991). These soils have evolved with fire as a natural, periodic ecosystem component. Prescribed fire will have little effect on soi l characteristics if burning is conducted within prescription. The use of a mosaic burn pattern, combined with unit size limitations, will minimize the overall impact to soils. Ignition will not occur within riparian zones & will avoid unstable soils and landslide prone areas. Treatment of fuels associated with these soil types will lower the probability of large wildfires occurring under peak burning conditions. Landslides A review of the CGS Preliminary Geologic Map for the Elledge Peak Quadrangle (2022) and Ukiah Quadrangle (2020), lidar imagery, and the Division of Mines and Geology, Open-File Report 91-16 and Landslide Hazard Identification Map No. 24 revealed multiple large unstable areas within the project area (Figure 4.6.2). These include mostly pre -historic or ancient Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 59 features, particularly in Gibson Creek, Spanish Creek, and Robinson Creek Watersheds. Note that the CGS map used for reference in this assessment is a preliminary map that should not be considered as an authoritative or comprehensive source for landslide and seismic hazard data. However, the features used here largely overlap with past reports by Sydnor (1991) and were considered to be helpful in addressing the impacts of this project. Gibson Creek headwaters is located within the northern portion of the project area. There is a large ancient feature mapped here (Sydnor 1991), in which an existing jeep trail traverses to the bottom where it connects to the road in Gibson Canyon. O n the hillshade image, this feature is characterized by very smooth ground, with some depressions and hummocky nature, as well as some older incised gullies along the margins. Moving south, other smaller features have been mapped within the watercourse channels and hillsides of the drainages flowing east towards Ukiah Valley. The southern part of the project area has one large ancient feature, recently remapped by Rubin (2022) that flows northeast into Spanish Canyon, with the headscarp being the east -southeast side of Spanish Mountain. Oak Knoll Road traverses through the body of the more northern portion of the feature and connects to the ridgeline. On the hillshade image, the ground appears hummocky and disrupted, and has disorganized drainage patterns. The third large feature is in the very southwest corner of the PIZ within the Robinson Creek Watershed and Robinson Creek Mélange. There is an existing control line treatment area within this feature that traverses from Hwy 253 up the hill through the feature. Landslide deposits are composed of rock fragments, finer sediment, soil, and biological matter and can have flowing mixtures, dropped blocks, or rotated blocks. IMPACT GEO-1 Mechanical disturbance activities in this project will include masticating target vegetation and chipping biomass from manual and mechanical treatment activities. Equipment would include tracked equipment, such as tractors/skidders, chippers, and masticators. Equipment would be operated on or within 100 feet of existing roads or skid trails in fuel break treatment areas and on existing roads or skid trails or on flat to moderate slopes in WUI treatment areas. Where trails are located on slopes over 50% within treatment areas, SPR GEO-7 prohibits heavy equipment use. Trails over 50% slope shall be avoided with heavy equipment and would be limited to manual vegetation treatments. As stated in the CalVTP PEIR Section 2.5.2, mechanical treatments may cut, uproot, crush/compact, or chop existing vegetation using masticators and other methods of application. This project proposes to limit mastication to the cutting or chopping of above -ground vegetation with the intent of keeping masticating heads out of duff laye rs and minimizing direct disturbance to subsurface soil layers, allowing intact root systems to resprout. Understory debris would be masticated or chipped on-site within the treated areas or piled and subsequently burned during wet periods of the year to dispose of accumulated biomass, pursuant to the standards defined in the PEIR (CalVTP Final PEIR Volume II Section 2.5.2, 22-24). Vegetation treatments would include manual and mechanical treatments, prescribed burning, and burn piles to remove biomass, which could result in varying levels of soil disturbance, including the exposure to people of fugitive dust emissions contain ing naturally occurring asbestos (discussed in Section 4.3), and have the potential to increase rates of erosion and loss of topsoil. The potential for these treatment activities to cause substantial erosion or loss of topsoil was examined in the PEIR. Mechan ical treatments using heavy machinery are the most likely to cause soil disturbance that could lead to substantial erosion or loss of topsoil, especially in areas which have previously burned in wildfires, and in areas containing steep slopes. Equipment used to create piles for burning may also increase the risk of soil disturbance. This impact is within the scope of the PEIR because the use of and type of equipment, extent of vegetation removal, and intensity of prescribed burning are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, the soil characteristics of the project area ar e essentially the same within and outside the treatable landscape; therefore, the potential impact related to soil erosion is also the same, as described above. SPRs applicable to this treatment project are GEO-1 through GEO-8, HYD-4, and AQ-4. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 60 The soil types within the PIZ have a High erosion hazard rating (EHR). The table below shall be used to determine the maximum distance between waterbreaks for all existing dozer lines, native soil road surfaces and skid trails. Any new trails lines created with heavy equipment shall have erosion control structures installed as per this table. Where there are locations that show evidence of past soil loss such as rilling or where potential serpentine soils occur, the Extreme EHR standard shal l be applied. IMPACT GEO-2 Treatment activities would include manual and mechanical vegetation removal, prescribed burning, as well as the creation of burn piles, in varied topography, which could decrease the stability of slopes and increase the risk of landslides. There are three larger “ancient” landslide features identified within the treatment areas (Sydnor 1991 and Rubin 2022). These are located on slopes generally less than 50% and are not known to have existing active erosion issues and have existing stable infrastructure located within their boundaries such as roads and developed pads. As per SPR GEO-8, an RPF or licensed Geologist shall identify in the field any unstable areas located within treatment areas with over 50% slopes prior to project implementation. Where identified features are unavoidable and will be potentially directly or indirectly affected by the treatment, a licensed geologist (P.G. or C.E.G.) will determine the potential for landslide, erosion, of other issue re lated to unstable soils and identity measures (e.g., those in SPR GEO-7) that will be implemented by the project proponent such that substantial erosion or loss of topsoil would not occur. This SPR applies only to mechanical treatment activities and WUI fuel reduction, and non-shaded fuel breaks treatment types, including treatment maintenance. There were no unstable areas identified from the lidar imagery within treatment areas where slopes are greater than 50% but have not been ground-truthed and shall be reviewed by an RPF or licensed geologist prior to project implementation. Given the variable topography, soil and rock types, active faulting, and prior wildfires that are natural to the treatment areas, risk of landslide activity remains. The potential for treatment acti vities to increase landslide risk was examined in the PEIR. This impact is within the scope of the PEIR because the extent of vegetation removal, intensity of prescribed burning, and characteristics of the geographical terrain are consiste nt with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, within the boundary of the project area, the range of slopes and landslide conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landsc ape. Therefore, the potential impact related to landslide risk is also the same, as describ ed above. SPRs applicable to the proposed project are GEO-1 through GEO-8, and AQ-3. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW GEOLOGY, SOILS, PALEONTOLOGY & MINERAL RESOURCE IMPACTS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.7.1, “Environmental Setting,” and Section 3.7.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to geology and soils that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact relate d to geology and soils would occur.

Prescribed burning and the use of vehicles and equipment during treatment activities will emit greenhouse gases. This project will utilize prescribed fire for WUI treatments and is consistent with applicable plans to reduce greenhouse gas emissions statewide as it aims to reduce the likelihood of catastrophic wildfires. Such an event would create immense GHG emissions in a short time span. This impact is within the scope of the PEIR because the proposed activities, associated equipment, duration of use, and the resulting GHG emissions are consistent with those analyzed in the PEIR. GHG EMISSIONS FROM GRASSLAND BURNS The above-ground carbon cycle in annual grasslands is essentially a one -year cycle in California’s Mediterranean climate. Grass sprouts in the fall or winter following adequate precipitation to initiate germination. Grass grows based on environmental factors such as temperature, soil moisture, and soil fertility. These same factors influence the rate of decay of the previous year’s grass crop. Most annual grasses mature in 60-120 days. As grass grows, they sequester carbon. As the previous grass crop decays, it releases the stored carbon. While the active growth of the grass is the only time that carbon is sequestered, release of carbon can take place at any time. The main carbon release mechanisms are decay, digestion (grazing), and fire. While small amounts of carbon may be added to the carbon stored in the soil, the majority is released back to the atmosphere where it is available to be sequestered by the next crop. Each day, more than 10% of the soluble carbohydrate pool degrades to CO2, about 0.34% of the cellulose pool degrades, and less than 0.1% of the lignin. Because annual grasslands do not generally carry biomass for more than a year, they are essentially carbon neutral on an annual basis. Prescribed burning of grassland units is generally completed in one or two days. The daily release of greenhouse gases during the proposed burning will be far greater than the normal daily emission from decay or digestion. The annual release would be essentially the same. Perennial grasslands maintain a portion of their biomass for more than a year. Most of the biomass of each year’s growth is released back to the atmosphere by decay or digestion. The carbon sequestration and release processes are essentially the sa me Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 63 as those of the annual grassland. When perennial grasslands are burned, they may have a greater annual release of carbon tha n an unburned area, proportional to fire intensity. In higher intensity grass fires, where significant amounts of the thatch a re burned, it may take two or three years to sequester the amount of carbon released in the year of the burn. Therefore, with respect to burning perennial grasslands, they are carbon neutral after two or three years. Wildfires generally have higher fire intensities than the controlled burns used in prescribed fire. In grassland habitats, prescribed fire can reduce flame lengths and rates of spread during subsequent wildfires by modifying vegetation structure and continuity. Prescribed burning removes accumulated thatch, thereby reducing the potential for a “ladder ef fect” that could carry flames into shrubs and ornamental vegetation. In addition, prescribed fire can enhance access and safety zones for firefighting perso nnel and support the development of defensible space and fuel break systems that remain effective beyond a single growing season. Within the wildland–urban interface, these benefits may persist for more than one year, as reduced fire behavior potential and improved tactical suppression opportunities continue to support wildfire risk mitigation. All of this leads to lower greenhouse gas emissions from catastrophic wildfire s. GHG EMISSIONS FROM CHAPARRAL BURNS Prescribed burning in chaparral vegetation results in short -term GHG emissions from the combustion of live and dead plant material. These emissions are temporary and occur over a limited duration during ignition and active burning. Although prescribed fire produces carbon dioxide, methane, and nitrous oxide, the magnitude of emissions is substantially lower than those generated during unmanaged wildfires in comparable fuel types. Conversely, wildfires in chaparral typically burn at higher intensities, consume a greater proportion of available biomass, and generate significantly higher GHG emissions per acre due to uncontrolled combustion conditions. Implementation of prescribed fire reduces long-term GHG emissions by lowering fuel loads and associated fire hazard by interrupting the accumulation of dense chaparral stands that contribute to extreme wildfire behavior. By reducing the potenti al, size, and severity of future wildfires, prescribed fire can offset a portion of the short -term GHG emissions through avoided wildfire emissions over time. This effect is particularly relevant in chaparral ecosystems, which naturally experience stand - replacing fire and can store large amounts of carbon that are rapidly released during high-severity wildfire events. In addition, prescribed fire promotes a more resilient vegetation structure that regenerates post-burn and begins re-sequestering carbon within a relatively short timeframe. This cyclical carbon uptake helps balance the temporary emissions from the prescribed burn. When implemented as part of a strategic fuels management program, prescribed fire can therefore provide a net climate benefit by mitigating the likelihood of catastrophic wildfire emissions, supporting long -term carbon stability, and improving landscape resilience to future climate-driven fire conditions. When evaluated in terms of avoided wildfire emissions, post -burn carbon recovery, and improved ecosystem resilience, prescribed burning in chaparral habitats is anticipated to result in substantial ecological and climate benefits. AIR RESOURCES BOARD (ARB) GHG INVENTORY WORK ARB has undertaken an extensive inventory documentation and refinement exercise to develop a draft updated statewide GHG emissions inventory and corresponding documentation. This statewide GHG inventory is an aggregate, "top -down" inventory for the period 1990-2004. The Board approved a 2020 emissions limit of 427 million metric tonnes of CO2 equivalent in December 2007. The 2020 emissions limit is equivalent to the 1990 emissions level (ARB 20 23). In California, the annual fossil fuel burning (FFB) emissions inventory of CO2 is 362 million metric tonnes CO2 per year averaged from 1990–2003. As such, the annual averaged emissions of CO2 from wildfires are significant (24 million metric tonnes CO2 per year; equivalent to 6% of the FFB emission estimates). Although the ratio of annual state -level CO2 emissions from fires to FFB sources is low, it is highly variable. By the end of October 2003, wildfires burned more than 750,000 acres, producing the equivalent of 49% of the monthly CO2 emitted by FFB sources for the state. Similarly, major wildfires in September 2006, including the Day Fire in Southern California, produced an estimated 16 million metric tons CO2 in that one month alone, equivalent to approximately 50% of estimated total monthly FFB emissions for the entire state (Wiedinmyer and Neff 2007). Far more acres are burned each year in wildfires than are burned in prescribed fires. To the extent that prescr ibed fire can lessen the intensity or reduce the acres burned in wildfires, prescribed fire can temporarily reduce the carbon emissions from the wildland. An important cause of carbon loss is catastrophic wildfires, especially in fire -adapted ecosystems (Helms 2007). Fire is one of the largest potential risks to loss of stored terrestrial carbon, and it is a loss pathway that is difficult to quantify due to the high degree of spatial and temporal variation in fire emissions. At multi-decadal time scales, wildfires have a near neutral effect on atmospheric CO2: vegetation regrowth balances punctuated carbon losses due to combustion, if fire return intervals remain Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 64 constant (Wiedinmyer and Neff 2007). Fuel reduction projects that do not change the vegetation type are carbon neutral over time. The time needed to sequester the amount of carbon released by the treatment is determined by the amount of carbon released and the subsequent regrowth of the vegetation. California’s wildlands are going to burn, and the carbon is going to be released. Through prescribed fire land managers can have a say in the timing and quantity of some of those releases. Land managers can also lessen the impacts or provide benefi ts for other environmental resources. Fire hazard reduction may be an objective of prescribed fire; however, other objectives such as, control of invasive species, wildlife habitat improvement, or range improvement are often also objectives. If a wil dfire does happen to enter an area that was treated, the wildfire may be contained sooner with reduced area burned and consequently reduced carbon emissions. The reduced number of acres or fire intensity may have benefits to other resource areas besides the reduction of carbon emissions. The reduced wildfire size or intensity may also have benefits to environmental resources, pub lic health, as well as public and firefighter safety. IMPACT GHG-1 The First Order Fire Effects Model (FOFEM) was used to determine the amount and type of emissions likely to occur with prescribed burning. Emission calculations for prescribed burning are based on factors including fuel models, fuel conditions and expected fuel consumption in tons per acre. Emission calculations for motorized equipment and vehicles are based on the California Air Resource Board emissions modeling tools, OFFROAD2021 ORION and the EMFAC2014. Initial burn units will produce 9,138 tons of CO2 from treatment activities and 27 tons of CO2 from motorized exhaust for a total annual average of 9,165 tons. Use of vehicles and mechanical equipment and prescribed burning during initial and maintenance treatments would result in GHG emissions. Consistency of treatments under the CalVTP with applicable plans, policies, and regulations aimed at reducing GHG emissions was examined in the PEIR. Consistent with the PEIR, although GHG emissions would occur from equipment and vehicles used to implement treatments, the purpose of the proposed project is to reduce wildfire risk, which could reduce GHG emissions and increase carbon sequestration over the long term. This impact is within the scope of the PEIR because the proposed activities, as well as the associated equipment, duration of use, and resultant GHG emissions, are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the same plans, policies, and regulations adopted to reduce GHG emissions apply in the areas outside the treatable landscape, as well as areas within the treatable landscape; therefore, the GHG impact is also the same, as described above. SPR GHG -1 is not applicable to the proposed project because this project is not a registered offset project under the Board’s Assembly Bill 1504 Carbon Inventory Process. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT GHG-2 Use of vehicles and mechanical equipment and prescribed burning during initial and maintenance treatments would result in GHG emissions. The potential for treatments under the CalVTP to generate GHG emissions was examined in the PEIR. This impact is within the scope of the PEIR because the proposed activities, as well as the associated equipment and duration of use, and the intent of the treatments to reduce wildfire risk and GHG emissions related to wildfire are consistent with those analyzed in the PEIR. Mitigation Measure GHG-2 would be implemented and would reduce GHG emissions associated with the prescribed burning. However, emissions generated by the treatments would still contribute to the annual emissions generated by the CalVTP, and this impact would remain significant and unavoidable, consistent with, and for the same reasons described in, the PEIR. SPR AQ-3 is also applicable to this treatment and will contain the description of feasible GHG reduction techniques implemented per Mitigation Measure GHG-2. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the climate conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the GHG impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW IMPACTS RELATED TO GHG EMISSIONS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable regulatory and environmental conditions presented in the CalVTP PEIR (refer to Section 3.8.1, “Regulatory Setting,” and Section 3.8.2, “Environmental Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 65 environmental conditions pertinent to the climate conditions that are present in the areas outside the treatable landscape ar e essentially the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact related to GHG emissions would occur. 4.7.2 GHG Emissions Summary All CAL FIRE prescribed burns receive a Smoke Management Permit from the Local Air District. A Smoke Management Plan is developed for each project, to further minimize smoke impacts. Burning is done on approved burns days as determined by the Air District. This process minimizes public health smoke impacts from the project. Prescribed burn projects undertaken by CAL FIRE are a strategic land management tool designed to reduce the risk of large- scale wildfires which can release substantially higher amounts of greenhouse gases than prescribed burns. By reducing fuel loads in grasslands, chaparral, and other working landscapes, these projects increase wildfire resilience while keeping the l and available to sequester carbon over the long term. Conversion of land to other uses such as factories or subdivisions would have a much greater increase in carbon emissions. Prescribed fires are also designed to achieve the landowners’ objectives, are carefully planned to minimize the area treated, and to consume the amounts of fuel necessary to meet the prescribed burn objectives. Prescribed burns are not initiated without specific burning objectives to be achieved. Because prescribed burns prevent larger, uncontrolled wildfires, they serve as a proactive climate mitigation strategy. As a result, it is not expected that prescribed burning of grasslands, oak woodlands or chaparral will cause a significant net increase in greenhouse gas emissions, and they contribute to reducing potential long-term GHG releases from catastrophic wildfires. We do not believe prescribed burning associated with this project will have a significant net effect on the annual release of greenhouse gases, nor will prescribed burning result in an increase in the long-term release of greenhouse gases from grassland, oak woodland or chaparral landscapes.

The use of fossil fuels for equipment and vehicles was examined in the PEIR. The consumption of energy during implementation of the treatment project is within the scope of the PEIR because the types of activities, as well as the associated equipment and duration of proposed use, are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, the existing energy consumption is essentially the same within and outside the treatable landscape; therefore, the energy impact is also the same, as described above.

The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable regulatory and environmental conditions presented in the CalVTP PEIR (refer to Section 3.9.1, “Regulatory Setting,” and Section 3.9.2, “Environmental Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions present in the areas outside the treatable landscape are essentially the same as thos e within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those considered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact r elated to energy resources would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.9.1 Hazardous Materials, Public Health & Safety Discussion IMPACT HAZ-1 Initial and maintenance treatments would include mechanical treatments, manual treatments, herbicide application, and prescribed burning. These treatment activities would require the use of fuels and related accelerants, which are hazardous materials. The potential for treatment activities to cause a significant health hazard from the use of hazardous materials was examined in the PEIR. This impact is within the scope of the PEIR because the types of treatments and associated equipment and types of hazardous materials that would be used are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, the exposure potential and regulatory conditions are essentially the same within and outside the treatable landscape; therefore, the hazardous material impact is also the same, as described above. SPR HAZ-1 is applicable to this treatment. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Project treatment activities require the transportation, use, and storage of petroleum products (fuels, oils, and lubricants) which are known hazardous materials and could cause significant health hazards to humans and the environment. CAL FIRE will apply SPR-HAZ 1 to minimize leaks and the risk of resultant contaminants from entering the environment. CAL FIRE requires daily safety inspections and a regular maintenance plan for all equipment to ensure that equipment is safe, functional, and f ree of leaks. Spill kits are kept with vehicles and equipment to contain fuel and/or hydraulic leaks should they occur. Locations Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 68 used for fueling the helicopter or servicing fire ignition systems are established in areas where spills can be easily and ra pidly contained (i.e. level ground) that are also outside of Watercourse and Lake Protection Zones and other sensitive areas. Most fueling activities for the project will occur offsite at CAL FIRE stations. The types of treatment, including equipment and t he use of hazardous materials, are consistent with the analysis in the PEIR and expected to be less than significant. IMPACT HAZ-2 Initial and maintenance treatments would include herbicide application to target plant species using ground -based methods, such as using a UTV or backpack sprayer or painting herbicide onto cut stems. No aerial spraying of herbicides would occur. The potential for treatment activities to cause a significant health hazard from the use of herbicides was examined in the PEIR. This impact is within the scope of the PEIR because the types of herbicides (e.g., glyphosate) and application methods that would be used, which are limited to ground-based applications, are consistent with those analyzed in the PEIR. In addition, herbicides would be applied by licensed applicators in compliance with all laws, regulations, and herbicide label instructions, consistent with herbicide use described in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the exposure potential is essentially the same within and outside the treatable landscape; therefore, the hazardous materials impact is also the same, as described above. SPRs HAZ -5 through HAZ-9 are applicable to this treatment. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT HAZ-3 Initial and maintenance treatments would include soil disturbance and prescribed burning, which could expose workers, the public, or the environment to hazardous materials if a contaminated site is present within the project area. The potential fo r workers participating in treatment activities to encounter contamination that could expose them, the public, or the environment to hazardous materials was examined in the PEIR. This impact was identified as potentially significant in the PEIR because hazardous materials sites could be present within treatment sites throughout the large geographic extent of the treatable landscape, and the feasibility of implementing mitigation for exposure of people or the environment to hazards resulting from soil disturbance or burning in a hazardous materials site was uncertain. As directed by Mitigation Measure HAZ-3, database searches for hazardous materials sites within the project area have been conducted (Figure 4.9-1). The Coast Wood Preserving site (SEMS EPA ID CAD063015887), located in the Ukiah Valley, on the eastern side of Hwy 101, approximately ½ mile from the nearest project dozer control line , is the only Federal Superfund project listed near the project site. Past lumber manufacturing activities for this site introduced contaminants, arsenic and chromium VI, into the surrounding soil and aquifer. Remediation is ongoing and includes soil monitoring and removal. The last remediation activities took place in 2019 (CalEPA 2023). Five other sites were listed for the SEMS search of Ukiah, however none of them are active. Eight other sites were listed for the EnviroSTOR search of Ukiah, of which three were listed as ‘Evaluation’1 sites, one was listed as ‘Corrective Action’2, two were listed as ‘School Investigation’3, one was listed as ‘Non- Operating’4, and one was listed as ‘Voluntary Cleanup’5 (DTSC 2023). After the implementation of MM HAZ-3, it was determined that no hazardous materials sites would be disturbed by treatments and impacts would be less than significant. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, within the boundary of the project area, the potential to encounter hazardo us materials and the regulatory conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the hazardous materials impact is also the same, as described above. No SPRs are applicable to this impact, and no additional mitigation is required. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. 1 ‘Evaluation’ project types identify suspected, but unconfirmed, contaminated sites. 2 ‘Corrective Action’ project types identify facilities that treat, store, dispose, and/or transfer hazardous waste. 3 ‘School Investigation’ project types identify proposed and existing school sites that are being evaluated by DTSC for possible hazardous materials contamination. 4 ‘Non-Operating’ project types identify a Treatment, Storage, Disposal or Transfer Facility (TSDTF) with no operating hazardous was te management unit(s). 5 ‘Voluntary Cleanup’ project types identify sites with either confirmed or unconfirmed releases, and the project proponents ha ve requested that DTSC oversee evaluation, investigation, and/or cleanup activities and have agreed to provide coverage for DTSC’s costs. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 69 NEW HAZARDOUS MATERIALS, PUBLIC HEALTH & SAFETY IMPACTS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.10.1, “Environmental Setting,” and Section 3.10.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determine d that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to hazardous materials that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact related to hazardous materials, public health, or safety would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.10.1 Hydrology & Water Quality Resources Discussion Several of the impacts below (i.e., HYD-1 through 4) evaluate compliance with water quality standards or waste discharge requirements. All include implementation of SPR HYD-1, which requires compliance with such water quality regulations. The State Water Resources Control Board is requiring all projects utilizing the CalVTP PEIR to follow the requirements of their Vegetation Treatment General Order, which would meet the requirements of SPR HYD-1. Users of the CalVTP PSA process are automatically enrolled in the General Order and are required to implement all applicable SPRs and mitigation measures from the PEIR. In addition, the General Order requires project proponents to comply with any appli cable Basin Plan prohibitions. A letter was sent to Jim Burke (Senior Engineering Geologist) of the North Coast Regional Water Quality Control Board (NCRWQCB) on February 19, 2024. That letter was then forward to Michael Hanks (Senior Environmental Scientist with the NCRWQCB), and a response was received on March 26, 2024. The response letter highlighted the standard project requirements (SPRs) for the project that are applicable to water quality impacts. These SPRs are included in Attachment A. IMPACT HYD-1 Initial and maintenance treatments would include prescribed burning. Ash and debris from treatment areas could be washed by runoff into adjacent drainages and streams. Although most treatment areas have been designed to avoid streams and watercourses, WLPZs ranging from 50 to 150 feet will be implemented for Class I and Class II streams that are within treatment areas pursuant to SPR HYD-4. Many water features have been identified during surveys and a pre-treatment walk-through of treatment areas will be conducted by a qualified RPF to identify unstable areas, equipment exclusion zones (EEZs), equipment limitation zones (ELZs), and any additional measures to protect water quality. Fire ignitions shall occur outside watercourse and lake protection zones but may be allowed to back into these areas. Prescribed burning will be managed to stay within the treatment areas to create a mosaic of habitat ranging from low to moderate burn intensities such that islands of unburned habitat will provide adequate ground cover for water filtration during precipitation events. Hence, high overland water flow and nutrient loss of soil will be avoided, and vegetation type conversion will not occur. The potential for prescribed burning activities to cause runoff and violate water quality regulations or degrade water quality was examined in the PEIR. This impact is within the scope of the PEIR because the use of low-intensity prescribed burns and associated impacts to water quality are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the surface water conditions are essentially the same within and outside the treatable landscape; therefore, the water quality impact from prescribed burning is also the same, as described above. SPRs applicable to this treatment are HYD-1 through HYD-4, BIO-4, GEO-4, GEO-6, AQ-3 and AQ-4 as well as MM Bio-3b. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 72 IMPACT HYD-2 Initial treatment would include mechanical and manual treatments. Although most treatment areas have been designed to avoid streams and watercourses, WLPZs ranging from 50 to 150 feet will be implemented for any watercourses that are within treatment areas pursuant to SPR HYD-4. Ground disturbance will be limited during precipitation, and heavy equipment will not operate over saturated soils (SPR GEO-1 & -2). Equipment operation will be limited on steep or unstable slopes (SPR GEO-7 and SPR GEO-8). Treatment areas will be inspected for erosion and remediated prior to the rainy season and following the first large rainfall event (SPR GEO-4). The potential for mechanical and manual treatment activities to violate water quality regulations or degrade water quality was examined in the PEIR. This impact is within the scope of the PEIR because the use of heavy equipment and hand- held tools to remove vegetation and associated impacts to water quality are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the surface water conditions are essentially the same within and outside the treatable landscape; therefore, the water quality impact from manual and mechanical treatments is also the same, as described above. SPRs applicable to this treatment are HYD-1, HYD-2, HYD-4 through HYD-6, GEO-1 through GEO-5, GEO-7, GEO-8, AQ-4, BIO-1, HAZ-1, HAZ-5, HAZ-6, and HAZ-8. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT HYD-3 This impact does not apply to the proposed project because prescribed herbivory is not a proposed treatment activity. IMPACT HYD-4 Initial and maintenance treatments would include the use of herbicides to manage invasive plant species and resprouting native tree species within the project area. Herbicide application would be limited to ground-based methods, such as using targeted spray from a backpack or reservoir carried by a UTV, or painting herbicide onto cut stems. All herbicide applications would comply with EPA and California Department of Pesticide Regulation label standards. The potential for the use of herbicides to violate water quality regulations or degrade water quality was examined in the PEIR. This impact is within the scope of the PEIR because the use of herbicides to remove vegetation and associated impacts to water quality are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, surface water conditions are essentially the same within and outside the treatable landscape; therefore, the water quality impact from use of herbicides is also the same, as described above. SPRs applicable to this treatment are HYD-1, HYD-5, BIO-4, HAZ-5, HAZ-6, HAZ-7, and HAZ-8. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT HYD-5 Initial and maintenance treatments could cause ground disturbance and erosion, which could directly or indirectly modify existing drainage patterns. Prescribed burning, and mechanical and manual vegetation removal for this project will have minor effects on site drainage. Control line preparation will require heavy equipment or hand crews. Waterbreaks will be installed and maintained on roads and skid trails, used for firing operations, and establishing control lines, to minimize soil loss utilizing the spacing and erosion control guidelines set forth in SPR HYD-4 and Impact GEO-1. This will ensure watercourses are hydrologically disconnected from sediment runoff. Existing drainage systems will be avoided and maintained at pre -treatment drainage conditions (SPR HYD-6). Many water features were identified during the biological survey, and a qualified RPF, qualified biologist, or their designee will walk through individual burn areas, prior to treatment activities, to identify an d map unstable drainage infrastructure. The potential for treatment activities to substantially alter the existing drainage pattern of a project site was examined in the PEIR. This impact to site drainage is within the scope of the PEIR because the types of treatments and treatment intensity are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, surface water conditions are essentially the same within and outside the treatable landscape; therefore, the impact related to alteration of site drainage patterns is also the same, as described above. SPRs applicable to this treatment are HYD-4, HYD-6, GEO-1, GEO-2, and GEO-5. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 73 NEW HYDROLOGY & WATER QUALITY IMPACTS The proposed treatment is consistent with the treatment types and activities considered in the CalVTP PEIR.

Any applicable county land use plan, policy, or regulation will be adhered to. The proposed project is consistent with the CAL FIRE Mendocino Unit 2023 Fire Plan. IMPACT LU-1 Vegetation treatment activities would occur within Mendocino County. SPR AD-3 requires CAL FIRE to comply with applicable county plans, policies, and ordinances, such as those pertaining to noise, biological resources, and water resourc es. This impact is within the scope of the PEIR because proposed treatment types and activities are consistent with those examined in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent considered in the PEIR. However, land uses in the project area are essentially the same within and outside the treatable landscape; therefore, the land use impact is also the same, as described above. No conflict would occur because the project proponent would adhere to AD-3. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than covered in the PEIR. IMPACT LU-2 The potential for initial treatments and maintenance treatments to lead to substantial population growth due to increased demand for employees. Prescribed burning treatment activities would necessitate between 10 and 50 crew members, depending on the size of the burn unit. Mechanical treatment activities may be conducted by up to four crews across each of the preserves. Herbicide treatments would typically use a one - to five-person crew, and manual treatments would be implemented by crews of approximately 8-20 members. Crew sizes would be consistent with those analyzed in the PEIR. Impacts associated with Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 75 short-term increases in the demand for workers during implementation of the treatment project are within the scope of the PEIR because the number of workers required for implementation of the treatments is consistent with the crew sizes analyzed in the PEIR for the types of treatments proposed. In addition, the proposed project would not require the hiring of new employees. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to t he geographic extent presented in the PEIR. However, the population and housing characteristics of the project area are essentially the same within and outside the treatable landscape; therefore, the population and housing impact is also the same, as described above. No SPRs apply to this impact. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than covered in the PEIR. NEW LAND USE AND PLANNING, POPULATION & HOUSING IMPACTS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.3.1, “Environmental Setting,” and Section 3.3.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable l andscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those cover ed in the PEIR. No changed circumstances are present, and the inclusion of areas outsid e of the CalVTP treatable landscape would not give rise to new significant impacts not addressed in the PEIR. Therefore, no new impact related to land use and planning would occur that is not covered in the PEIR.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.12.1 Noise Discussion IMPACT NOI-1 Initial and maintenance treatments would require heavy, noise-generating equipment. The potential for a substantial short-term increase in ambient noise levels from use of heavy equipment was examined in the PEIR. This impact is within the scope of the PEIR because the number and types of equipment proposed, and the duration of equipment use, are consistent with those analyzed in the PEIR. The proposed treatments would require limited use of helicopters during the active burn operations. While there is the potential for some prescribed burning to occur during nighttime and weekend hours, all treatment activities using equipment would be limited to daytime hours Monday through Friday, which would avoid the potential to cause sleep disturbance to residents during the more noise- sensitive evening and nighttime hours. In addition, treatments would be dispersed among the four preserves so that noise increases at any one sensitive receptor would be limited. Treatments would be within the preserves, which contain very few sensitive receptors, and use of equipment would be temporary and sporadic. Although Pole Mountain Preserve is open to the public for hiking, treatment activities would not take place near the same people for an extended period. SPR AD-1 is applicable to this treatment as well as NOI-1 through NOI-6. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the exposure potential to any sensitive receptors present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the noise impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Consistent with SPR NOI-1 the project proponent will require that operation of heavy equipment associated with treatment activities (heavy off-road equipment, tools, delivery of equipment and materials, and limited helicopter operation) will occur during daytime hours if such noise is audible to receptors. Treatment activities will be limited to regular business hours, 0800 - 1700 hours, Monday through Friday. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 77 Consistent with SPR NOI-2 all CAL FIRE vehicles and equipment are regularly maintained on a schedule and checked daily to ensure that all equipment is safe and compliant with all local, state, and federal laws governing noise and emissions. Consistent with SPR NOI-3 the project proponent will require that engine shrouds be closed during equipment operation. This SPR applies only to mechanical treatment activities and all treatment types. Consistent with SPR NOI-4 staging areas will be placed away from residences and other noise sensitive receptors. All staging areas will be decided on by the project proponent and applicable landowner. Consistent with SPR NOI-5 the project proponent will require that all motorized equipment be shut down when not in use, Idling of equipment and haul trucks will be limited to 5 minutes. This applies to all treatment activities and treatment type s. Consistent with SPR NOI-6 the majority of the project area is situated on rural parcels upslope of the Ukiah Valley. Most treatment activities are well over 1,500 feet away from noise-sensitive receptors. However, should shaded fuel break work occur within 1,500 feet of a residence, school, or place of worship the project proponent will notify noise-sensitive receptors. IMPACT NOI-2 Initial and maintenance treatments would involve large trucks hauling heavy equipment to the project area. These haul truck trips would be dispersed on area roadways providing access to the project site including SR 128 and Franz Valley Road. Vehicle traffic on area highways is not expected to generate a noticeable increase in traffic-related noise. Haul truck trips on the local roadways would pass by residential receptors and the event of each truck passing by could increase the single event noise levels (SENL). The potential for a substantial short-term increase in Single-Event Noise Levels was examined in the PEIR. This impact is within the scope of the PEIR because the number and types of equipment proposed are consistent with those analyzed in the PEIR. The haul trips associated with the treatment would occur during daytime hours (NOI-1), which would avoid the potential to cause sleep disturbance to residents during the more noise -sensitive evening and nighttime hours. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the exposure potential is essentially the same within and outside the treatable landscape; therefore, the noise impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Consistent with SPR NOI-1 the project proponent will require that operation of heavy equipment associated with treatment activities (heavy off-road equipment, tools, delivery of equipment and materials, and limited helicopter operation) will occur during daytime hours if such noise is audible to receptors. Treatment activities will be limited to regular business hours, 0800- 1700 hours, Monday through Friday. NEW NOISE IMPACTS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.13.1, “Environmental Setting,” and Section 3.13.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to noise that are present in the areas outside the treatable landscape are essentially the sa me as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact related to noise would occur.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.13.1 Public Services, Utilities & Service Systems Discussion IMPACT UTIL-1 Initial and maintenance treatments would include prescribed burning, which may require an on -site water supply if the burn goes out of prescription. If needed, water would be supplied from water trucks. The potential increased demand for water was examined in the PEIR. This impact is within the scope of the activities and impacts addressed in the PEIR because the size of the area proposed for prescribed burn treatments, amount of water required for prescribed burning, and water source type are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outsid e the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the water supplies present in the areas outside the treatable landscape are essentially the same as thos e within the treatable landscape; therefore, the water supply impact is also the same, as described above. No SPRs are applicable to this impact. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 79 IMPACT UTIL-2 Initial and maintenance treatments would generate biomass because of vegetation removal within the treatment areas. Biomass generated by mechanical and manual treatments would be disposed of with pile burning or mulching or lopping and scattering biomass in areas where material cannot safely be burned. Invasive plant and noxious weed biomass would also be treated onsite (e.g., prescribed burning), when possible, to eliminate seed and propagules; however, invasive plants and noxious weeds will not be chipped and spread, scattered, or mulched onsite. If invasive plant biomass cannot be treated onsite, there is the pot ential for a small amount to be disposed of offsite at an appropriate waste collection facility. This impact was identified as potentially significant and unavoidable in the PEIR because biomass hauled off-site could exceed the capacity of existing infrastructure for handling biomass. For the proposed treatment project, little to no biomass would be hauled off-site; therefore, the amount of biomass generated is not expected to exceed the capacity of existing infrastructure. SPR UTIL -1 would be applicable to the proposed treatments if biomass is hauled off-site. Implementation of this SPR would maintain impacts at less than significant, and mitigation is not required. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, conditions related to biomass in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, impacts related to biomass are also the same, as described above. IMPACT UTIL-3 As discussed above, initial and maintenance treatments would generate biomass because of vegetation removal within the treatment areas. Biomass generated by mechanical and manual treatments would be disposed of with pile burning or mulching or lopping and scattering biomass in areas where material cannot safely be burned. Invasive plant and noxious weed biomass would also be treated onsite, when possible. If invasive plant biomass cannot be treated onsite, there is the potential for a small amount to be disposed of offsite at an appropriate waste collection facility. If offsite disposal is required, CAL FIRE would comply with all federal, state, and local management and reduction goals, statutes, and regulations r elated to solid waste. Compliance with reduction goals, statutes, and regulations related to solid waste was examined in the PEIR. This impact is within the scope of the activities and impacts addressed in the PEIR because the type and amount of biomass that may need to be hauled off-site are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the biomass conditions in the areas outside the treatable landscape are essentially the sam e as those within the treatable landscape; therefore, impacts related to biomass are also the same, as described above. SPR UTIL-1 would be applicable to the proposed treatments if biomass is hauled off-site. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW IMPACTS ON PUBLIC SERVICES, UTILITIES & SERVICE SYSTEMS The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.16.1, “Environmental Setting,” and Section 3.16.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determine d that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to public services and utilities that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances are present, and the inclusion of areas outside of the CalVTP treatable landscape would not give rise to any new significant impacts. Therefore, no new impact related to public services, utilities, or service systems would occur.

Treatment activities could result in temporary closure of or limit access to the public trail and golf course if treatment activities are occurring in the vicinity of either recreational use open space lands. Initial and maintenance treatments would not restrict access to or otherwise affect the other adjacent recreation sites or facilities. The potential for vegetation treatment and maintenance activities to disrupt recreation activities was examined in the PEIR. The potential for the proposed treatment project to impact recreation is within the scope of the PEIR because the treatment activities and intensity are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalV TP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, the availability of recreational resources within the project area is essentially the same within and outside the treatable landscape; therefore, the impact on recreation is also the same, as described above. The SPR applicable to this treatment is REC-1. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than covered in the PEIR. NEW RECREATION IMPACTS The proposed project is consistent with the treatment types and activities considered in the CalVTP PEIR.

The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas co nstitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental conditions pertinent to recreation that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those covered in the PEIR.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.15.1 Transportation Discussion IMPACT TRAN-1 Initial and maintenance treatments would temporarily increase vehicular traffic along several roads in the project area, including Highway 101, State Route 128, and Franz Valley Road. The potential for a temporary increase in traffic to conflict with a program, plan, ordinance, or policy addressing roadway facilities or prolonged road closures was examined in the PEIR. The proposed treatments would be short term, and temporary increases in traffic related to treatments are within the scope of the PEIR because the treatment duration and limited number of vehicles (i.e., heavy equipment transport, crew vehicles for crew members) associated with the proposed treatments are consistent with those analyzed in the PEIR. In addition, the proposed treatments would not all occur concurrently, and increases in vehicle trips associated with the treatments would be dispersed on multiple roadways in two different geographic areas (i.e., coastal preserves and Russian River Watershed preserves). The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing transportation conditions (e.g., roadways and road use) present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the transportation impact is also the same, as described above. SPRs applicable to this treatment are AD-3, AD-4, AD-5, and TRAN-1. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 82 IMPACT TRAN-2 Initial and maintenance treatments would not require the construction or alteration of any roadways. However, the proposed treatments would include prescribed burning, which would produce smoke and could potentially affect visibility along nearby roadways such that a transportation hazard could occur. The potential for smoke to affect visibility along roadways during implementation of the treatment project was examined in the PEIR. This impact is within the scope of the activities and impac ts addressed in the PEIR because the burn duration is consistent with that analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presente d in the PEIR. However, within the boundary of the project area, the existing transportation conditions (e.g., roadways and road use) present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the transportation impact is also the same, as described above. SPRs applicable to this treatment are AD -3, HYD-2, and TRAN-1. This determination is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. IMPACT TRAN-3 Initial and maintenance treatments could temporarily increase vehicle miles traveled (VMT) above baseline conditions because the treatment areas are in remote locations and would require vehicle trips to access the treatment areas. This impact was identified as potentially significant and unavoidable in the PEIR because implementation of the CalVTP would result in a net increase in VMT. However, as noted under Impact TRAN-3 in the PEIR, individual vegetation treatment projects under the CalVTP are reasonably expected to generate fewer than 110 trips per day, which would cause a less -than-significant transportation impact for specific later activities, as described in the Technical Advisory on Evaluating Transportation Impacts, published by the Governor’s Office of Planning and Research (OPR 2018). Initial treatments are expected to require up to 50 crew members, which would not exceed 110 trips per day. Temporary increases in VMT are within the scope of the activities and impacts addressed in the PEIR because the number and duration of increased vehicle trips is consistent with that analyzed in the PEIR. The inclusion of land in the proposed treat ment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing transportation conditions (e.g., roadways and road use) present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the transportation impact is also the same, as described above. This determination is consistent with the PEIR and would not constitute a less than significant impact. NEW IMPACTS TO TRANSPORTATION The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatments and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.15.1, “Environmental Setting,” and Section 3.15.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determine d that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to transportation that are present in the areas outside the treatable landscape are essential ly the same as those within the treatable landscape; therefore, the impacts are the same and, for the reasons described above, impacts of the proposed treatment project are also consistent with those covered in the PEIR.

Yes No If yes, complete row(s) below and discussion Potentially Significant Less Than Significant with Mitigation Incorporated Less Than Significant [identify new impact here, if applicable; add rows as needed] 4.16.1 Wildfire Discussion IMPACT WIL-1 Vegetation treatment activities proposed would include mechanical, manual, herbicide application, and prescribed burn treatments. Vegetation treatment involving motorized equipment could pose a risk of accidental ignition. Temporary increases in risk associated with uncontrolled fire from prescribed burnings could also occur. As discussed in Section 3.17.1, “Environmental Setting,” in Volume II of the Final PEIR, under “Prescribed Burn Planning and Implementation,” implementing a prescribed burn requires extensive planning, including the preparation of prescription burn plans, smo ke management plans, site-specific weather forecasting, public notifications, safety considerations, and ultimately favorable weather conditions so a burn can occur on a given day. Prior to implementing a prescribed burn, fire containment lines would be established by clearing vegetation surrounding the designated burn area to help prevent the accidental escape of fire. Water containers and safety equipment would be staged on site as necessary. The potential increase in exposure to wildfire during implementation of treatments was examined in the PEIR. Increased wildfire risk associated with the use of heavy equipment in vegetated areas and with prescribed burns is within the scope of the PEIR because the types of equipment and treatment duration and the types of prescribed burn methods proposed as part of the project are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the wildfire risk of the project area is essentially the same within and outside the treatable landscape; therefore, the wildfire impact is also the same, as described above. SPRs HAZ -2, HAZ-3, and HAZ-4, pertaining to preparation of burn plans in accordance with CAL FIRE requirements, equipment safety requirements, keeping fire extinguishers, and prohibiting smoking in vegetated areas, apply to the proposed treatments. This impact of the proposed project is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. Docusign Envelope ID: 01DE84EB-A9BB-4CCC-ACAC-8D119FF98BE9 84 IMPACT WIL-2 Vegetation treatment types would include mechanical and manual vegetation treatment, herbicide application, and prescribed burning, which could exacerbate fire risk as described in Impact WIL -1 above. The potential for post-fire landslides and flooding was evaluated in the PEIR. The potential exposure of people or structures to post -fire landslides and flooding are within the scope of the activities and impacts covered in the PEIR because the equipment types and duration, and methods of prescribed burn implementation are consistent with those analyzed in the PEIR. The inclusion of land in the proposed treatment area that is outside the CalVTP treatable landscape constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the wildfire risk of the project area is essentially the same within and outside the treatable landscape; therefore, the wildfire impact is also the same, as described above. SPRs applicable to this impact are AQ-3 GEO-3 through GEO-5, and GEO-8. Although most mechanical treatment would occur from existing roads or skid trails or on flat to moderate slopes, SPR GEO-8 would apply if a treatment area contained steep slopes. Furthermore, because the treatments reduce wildfire risk, they would also decrease post wildfire landslide and flooding risk in areas that could otherwise burn in a high-severity wildfire without treatment. This impact of the proposed project is consistent with the PEIR and would not constitute a substantially more severe significant impact than what was covered in the PEIR. NEW IMPACTS ON WILDFIRE The proposed treatments are consistent with the treatment types and activities considered in the CalVTP PEIR. The project proponent has considered the site-specific characteristics of the proposed treatment project and determined they are consistent with the applicable environmental and regulatory conditions presented in the CalVTP PEIR (refer to Section 3.17.1, “Environmental Setting,” and Section 3.17.2, “Regulatory Setting,” in Volume II of the Final PEIR). The project proponent has also determined that including land from outside the CalVTP treatable landscape in the proposed treatment areas constitutes a change to the geographic extent presented in the PEIR. However, within the boundary of the project area, the existing environmental and regulatory conditions pertinent to wildfire that are present in the areas outside the treatable landscape are essentially the same as those within the treatable landscape; therefore, the impacts of the proposed treatment project are also consistent with those covered in the PEIR. No changed circumstances would give rise to new significant impacts not addressed in the PEIR. Therefore, no new impact related to wildfire would occur that is not covered in the PEIR.
