Item No.: 4.a
Date: 4/8//21
To: Board of Directors
Subject: Discussion and Possible Appointment of Tribal Stakeholder Director
Consent Agenda Regular Agenda Noticed Public Hearing
Summary:
Article 7 of the Joint Powers Agreement (JPA) provides that one stakeholder director shall be a
representative of tribal stakeholders and interest with the Basin. One Tribal Stakeholder
Director shall be appointed by the six tribes exercising jurisdiction over Indian lands within the
Ukiah Valley Basin identified as Redwood Valley Rancheria, Coyote Valley Reservation,
Pinoleville Pomo Nation, Potter Valley Rancheria, Guidiville Rancheria and the Hopland
Reservation.
Section 7.3.2 (b) of the JPA provides that the Board of Directors confirm the nomination for the
Tribal Stakeholder Director submitted by the six Tribes within the Ukiah Valley. The Member
Directors shall confirm the nominee at a regular meeting and shall appoint the Tribal
Stakeholder Director upon simple majority vote of all Member Directors.
Recommended Action:
1. Review the nominees submitted by the six Tribes within the Ukiah Valley and confirm
appointment of the Tribal Stakeholder Director and Alternate Director to the Board.
Background:
In 2019, the six Tribes of the Ukiah Valley Basin nominated Brandi Brown, Redwood Valley
Tribal Treasurer as Tribal Stakeholder Director and Sonny Elliott Jr., Hopland Reservation as
Alternate Stakeholder Director for a two year term representing Tribal interests on the UVBGSA
Board and TAC.

Subject: Discussion and Possible Adoption of the Proposed Fiscal Year 2021-2022 Budget
Consent Agenda Regular Agenda Noticed Public Hearing
Summary:
The Joint Powers Agreement (JPA) requires that the Agency adopt a budget pursuant to the
schedule and provisions described below. The Board should review the current financial status
and consider the proposed FY 2021-2022 budget for adoption.
Recommended Action:
Adopt the Proposed Fiscal Year 2021-2022 Budget.
Background:
Section 15.1 requires within (90) days after the first meeting of the Governing Board of the
Agency and thereafter prior to the commencement of each fiscal year (July 1st), the Board of
Directors adopt a budget for the Agency for the ensuing fiscal year.
The Trust Account FY 2020-21 year-end projected balance is $6,787. FY 2021-22 appropriates
$6,750 of the Trust Account for the administration of the UVBGSA.
Once financial estimates for the implementation of the Groundwater Sustainability Plan are
finalized and decisions are made as to funding mechanism, the FY 2021-22 budget may need to
be amended.
The County of Mendocino manages the Trust Account and the budget is administered by the
Mendocino County Water Agency. This management structure allows the County to include
UVBGSA in the County’s annual audit, therefore meeting the UVBGSA audit requirement.
Fiscal Summary: $6,750

Chronic lowering of groundwater levels is considered
significant and unreasonable when such lowering threatens the
long-term viability of domestic, agricultural, municipal, or
environmental users of groundwater.
Sustainable Management Criteria
Undesirable Results
▪Causes
▪Criteria to Define Undesirable
Results
▪Potential effects of Undesirable
Results on Beneficial Uses and
Users of Groundwater
▪Relationship to other
Sustainability Indicators
Significant and unreasonable degradation of groundwater
quality is the degradation of water quality that would impair
beneficial uses of groundwater within the Basin or result in
failure to comply with groundwater regulatory thresholds.
An undesirable result occurs when subsidence substantially
interferes with beneficial uses of groundwater and land uses.
Depletion of surface water due to groundwater extraction is
considered significant and unreasonable when such lowering
threatens the long-term viability of domestic, agricultural,
municipal, or environmental users of groundwater.

The overall sustainability goal of groundwater management in the Basin is to maintain ground-water resources in ways that
best support the continued and long-term health of the people, the environment, and the economy in Ukiah Valley, for
generations to come. This includes managing groundwater conditions for each of the applicable sustainability indicators in the
Basin so that:
◼Groundwater elevations and groundwater storage do not significantly decline below their historically measured range,
protect the existing well infrastructure from outages, protect groundwater-dependent ecosystems, and avoid significant
additional streamflow depletion due to groundwater pumping.
◼Groundwater quality is suitable for the beneficial uses in the Basin and is not significantly or unreasonably degraded.
◼Significant and unreasonable land subsidence is prevented in the Basin. Infrastructure and agricultural production in Ukiah
Valley remain safe from permanent subsidence of land surface elevations.
◼Significant and undesirable streamflow depletions due to groundwater pumping are avoided through projects and
management actions consistent with existing regulatory requirements.
◼The GSA’s groundwater management is efficiently and effectively integrated with other water -shed and land use planning
activities through collaborations and partnerships with local, state, and federal agencies, private landowners, and other
organizations, to achieve the broader “watershed goal” of sufficient surface water flows that sustain healthy ecosystem
functions.

Foreword
◼We are discussing SMC with the TAC and Working Groups.
◼SMC will change based on your input
◼Setting them is an iterative process
◼We believe what we are proposing is protective of beneficial uses, provides
operational flexibility, and is a good starting point
◼We are using the model to see how these settings will fit in the future
◼SMC can differ based on location of well, area, or hydrogeology. They are
not one size fits all.
◼They can be changed as more data becomes available at 5-year reviews.
◼Crossing MTs does not necessarily mean non-compliance. Meeting
undesirable result conditions does.
◼We have 20 years + a possible 5-year extension to reach MOs sustainably.

Sustainable Management Criteria
Monitoring Networks
◼A set of CASGEM wells and TSS Wells are used for all networks to measure
GWE.
◼A set of streamflow gages are used for ISW.
◼TSS Wells and a few of CASGEM instrumentations are still being coordinated
and implemented.
◼1 Streamflow gage installed, 1 is planned, 4 USGS gages are available.
◼Continuous measurements will be reported monthly, CASGEM frequency
reported twice per year, and streamflow measurements will be reported daily.

Sustainable Management Criteria
Monitoring Networks
◼A set of public supply wells already monitored for DDW + 4 TSS wells
◼DDW wells are monitored by the agencies –TSS by the GSA
◼We follow the same schedule as the DDW
◼Boron will be sampled at the request of GSA by agencies
◼Monitoring will be done by tracking DWR published data

◼To achieve the sustainability goal and Measurable Objectives
◼GSA can coordinate its efforts and PMAs with the current efforts for draught management to better serve the
community
◼Projects
⚫Can be done in phases: Feasibility, Design, Pilot, Implementation
⚫Can be existing or planned, short-term (2022-2027) and long-term (2027-2042).
◼Management actions
⚫Do not need capital investments and may have triggers for implementation.
⚫May also be existing or planned, short-term (2022-2027) and long-term (2027-2042).
◼Categorized into:
⚫Conjunctive Use
⚫Supply Augmentation
⚫Water Conservation
⚫Water Quality Enhancement
◼Current list of PMAs are in discussion and investigation process and presented for informational
purposed only.
