6.B. - Page 2 of 16 • Construction of new on-site pipeline between the new water tank and new pump station on the project site; • Construction of a new 2,000 foot long transmission pipeline from the new tank to an existing pipeline at Jefferson Avenue and Fallen Leaf Way, to serve as the pumping line from Lakeview Water Station to the new tank; • Replacement of the existing California Pump Station; and • Installation of a new emergency power generator to service the new pump station. On April 8, 2019, City Council awarded the Project construction to Anderson Pacific Engineering Construction, Inc. Construction is expected to begin approximately in two months and be completed within the next two years. A Mitigation, Monitoring and Reporting Program (MMRP) was prepared for the project, in connection with certification of a Final Environmental Impact Report, pursuant to the California Environmental Quality Act (CEQA). The MMRP required a dust control plan for earth work of serpentine rock. Serpentine soil was observed in all geotechnical soil boring samples collected from the project site, and an asbestos dust mitigation plan (ADMP) was prepared, per the California Code of Regulations (CCR) Title 7, Section 93105, Asbestos Airborne Toxic Measures for Construction, Grading and quarrying and Surface Mining Operations. The ADMP required an environmental consultant to oversee and monitor dust mitigation of earth work. SCA Environmental, Inc. has been qualified and selected to work on this project as part of the consultant design team since the early stages of the project. They performed asbestos dust testing, and provided specification review and recommendations during the design phase of the project. ANALYSIS SCA Environmental, Inc. will provide Environmental Services during construction such as air monitoring and reporting, as required by the ADMP, for specific earth work tasks outlined below related to the construction of the proposed structure and pipelines. ■ Mass Grading ■ Aggregate Pier Installation -Tank Foundation ■ Soil Nail Installation -Retaining Wall ■ Spread Footing Excavation ■ Trenching for Underground Utilities In addition to the observation and testing of the above noted construction activities, the Consultant will perform laboratory testing as necessary to document compliance with the Project Documents to confirm the field observations; and provide consultation as needed for the project. FISCAL IMPACT Funds were previously appropriated in the Water Fund Capital Projects Fund - California Pump House and Generator Project in the Fiscal Year 2018-2019 budget and a balance of $1,371,769 is available as of June 30, 2019.
