Director of Public Works City of Ukiali(City) 300 Seminary Avenue Ukiah, CA 95482-5400 RE: AMENDMENT TO FINAL CONSTRUCTION DESIGN CONTRACT CITY OF UKIAH LANDFILL MENDOCINO COUNTY,CALIFOI2NIA Dear Tim: Per your request during our site meeting on August 14, 2013, EBA Engineering(EBA) has prepared this amendment to the existing final construction design contract associated with the final closure oF the City of Ukiah Landfill (Landfil]). At the time of our meeting, the remaining balance of the February 6, 2007 contract as reported by the City was $57,587. Additiona]tasks have become necessary since the previous agreement due to changes in the final cover design and new regulations. These additional tasks can be summarized as follows: • Stabili Analysis: Perform laboratory testing and subsequent design analysis to account for the I addition of a gas relief layer to the £nal cover system. Also review potential replacement of the previously proposed 6-inch sand drainage layer with a geonet composite drainage layer as a potential cost savings measure. I • Supplenaental ToDOrra�hic Survev: Perform field topography to supplement the aerial survey I photogrammetric mapping provided by the City. This field topography will consist of I topographic features within the project limits that affect the design including manholes and i inverts on the leachate collection system, locations and inverts on the existing storm drain and leachate outfalls, and any conhol that is needed to tie the older and recent topography surveys , together horizontally. ' • Permittingfor New Sta�m Drain Outfalls: Coordinate, complete permitting applications, and I address comments for permitting associated with the new storm drain outfalls into the creek. The anticipated permits for the storm drain outfalls are: California Department of Fish and Game Streambed Alteration Agreement; North Coast Regional Water Quality Control Board 401 permit;and the United States Army Corp of Engineers 404 peanit. Services include an initial site meeting and one additional site meeting that may be required with the permitting agencies. Based i on similar projects and experience, it is assumed that the permitting associated with the above � agencies will not include any biological or archaeological assessments, California Environmental Quality Act (CEQA) documentation, eta [f during the permitting process any of these I assessments or CEQA documentation is required, EBA will notify the City accordingly and discuss any additional services prior to proceeding.

Services will include: LFG sampling and testing; preparation of a Design Plan meeting AB32 requirements; preparation of design drawings, technical specifications, and engineer's cos[ estimate; bidding assistance for the acquisition of a flare; and coordination and acquisition of an Authority to Consiruct permit from the Mendocino County Air Qualiry Management District. Please note that EBA recommends that the Ciry purchase the flare directly as opposed to including this task as part of the final dosure construction bid. This approach will eliminate any contractor markup on the flare, which would result in a $10,000 to $20,000 cost savings. Under this scenario, the contractor for the final closure construction project would still be made responsible for installing the flare. EBA's cost presented herein includes prepazation of a separate bid package for flare manufacturers,as wel] as subsequent bid coordination and review. The following provides a breakdown of the additional costs for the respective tasks described above. As agreed upon during our August 14, 2013 site meeting, the costs were developed using EBA's current billing rates. • StabilityA»alysis: $ 9,500 • Supplenaental Topographic Survey: $ 4,000 • Pernzitting,for New Storm Drain Outfalls: $ 4,500 • LFG Collection System Design and Pennittirag.• 42 980 • Total Additional Costs: 8 60,980 A copy of EBA's Standard Schedule of Fees and Rates reflecting our current billing rates is attached. In addition to using these rates to perfonn tlie aforementioned additional services, these billing rates will also be used for the existing wntract balance for the final construction design as agreed upon during our August 14, 2013 site meeting. EBA appreciates the opportunity to be of service to the City on this project. If you should have any questions regarding this amendment, please do not hesitate to contact ow office at(707)544-0784.
