NOTICE of PREPARATION Waterfix EIR for WSC Amendments
July 13, 2018 NOTICE OF PREPARATION Environmental Impact Report For the Proposed SWP Water Supply Contract Amendments for Water Management and California WaterFix July 13, 2018 INTRODUCTION Pursuant to the California Environmental Quality Act (CEQA), the Department of Water Resources (DWR) will be the Lead Agency and will prepare an Environmental Impact Report (EIR) for the proposed State Water Project Water Supply Contract Amendments for Water Management and California WaterFix (proposed project). As more fully discussed below, this proposed project includes amending certain provisions of the State Water Resources Development System (SWRDS) Water Supply Contracts (Contracts). SWRDS (defined in Water Code Section 12931), or more commonly referred to as the State Water Project (SWP), was enacted into law in the Burns-Porter Act, passed by the Legislature in 1959 and approved by the voters in 1960. DWR constructed and currently operates and maintains the SWP, a system of storage and conveyance facilities that 1 provide water to 29 State Water Contractors known as the Public Water Agencies (PWAs). These PWAs include local water agencies and districts legislatively enabled to serve irrigation, municipal and industrial water supply customers or retail water supply 1 The State Water Project Public Water Agencies include Alameda County Flood Control and Water Conservation District (Zone 7), Alameda County Water District, Antelope Valley-East Kern Water Agency, Castaic Lake Water Agency, City of Yuba City, Coachella Valley Water District, County -

3.12 Hydrology and Water Quality
3.12 HYDROLOGY AND WATER QUALITY EXECUTIVE SUMMARY This section describes the drainage features, stormwater quality, flooding hazards, and flood-protection improvements within the City’s Planning Area. Regulatory agencies governing stormwater quality and flooding hazards are also discussed. The City’s Planning Area is comprised of the City’s boundaries and adopted Sphere of Influence (SOI). The County’s Planning Area consists of unincorporated land within the One Valley One Vision (OVOV) Planning Area boundaries that is outside the City’s boundaries and adopted SOI. Together the City and County Planning Areas comprise the OVOV Planning Area. With implementation of the proposed General Plan goals, objectives, and policies potential impacts on hydrology and water quality would be less than significant. EXISTING CONDITIONS Surface Water Drainage Patterns within City’s Planning Area Surface water drainage patterns are dependent on topography, the amount and location of impervious surfaces, and the type of flood control that is located in an area. The size, or magnitude, of a flood is described by a term called a “recurrence interval.” By studying a long period of flow record for a stream, hydrologists estimate the size of a flood that would have a likelihood of occurring during various intervals. For example, a five-year flood event would occur, on the average, once every five years (and would have a 20 percent chance of occurring in any one year). Although a 100-year flood event is expected to happen only once in a century, there is a 1 percent chance that a flood of that size could happen during any year. -

APPENDIX B Alternatives Development
APPENDIX B Alternatives Development Introduction In 2001, the U.S. Department of the Interior, Bureau of Reclamation, Mid-Pacific Region (Reclamation), California Department of Water Resources (DWR), and Contra Costa Water District (CCWD) began appraisal-level studies of the potential to expand Los Vaquero Reservoir to address regional water supply reliability and water quality needs. Expansion of Los Vaqueros was one of five potential surface water storage projects identified by the CALFED Bay-Delta Program (CALFED) as warranting further study. The appraisal-level studies indicated that expanding the reservoir by as much as 400,000 acre-feet was technically feasible and could provide water quality and water supply reliability to Bay Area water agencies in the region and also provide potential benefits to fisheries sensitive to water management operations in the Sacramento-San Joaquin Delta (Delta). Reclamation was directed by the Omnibus Appropriations Act of 2003 to conduct a feasibility-level investigation of the potential expansion of Los Vaqueros Reservoir. This appendix contains a description of the comprehensive alternatives development process initiated after voters in the CCWD service area approved an advisory measure in 2004 to continue investigating the potential for expansion of Los Vaqueros Reservoir. The alternatives development process was based partly on the Project Concept Report (CCWD, 2002) and the Final Draft Planning Report (CCWD, 2004). The process resulted in the development of four action alternatives which are evaluated this Draft Environmental Impact Statement/Environmental Impact Report (EIS/EIR). The No Project/No Action Alternative is also discussed. The alternatives development process consisted of the following three steps: • Initial concepts • Initial plans • Alternatives development and refinement This appendix also includes a summary of the evaluation of alternative sites for project components including intakes, pipelines, and conveyance facilities that are included in the action alternatives. -
Energy and Water Co-Benefits from Covering Canals with Solar Panels B
Nature Sustainability, 2021 https://doi.org/10.1038/s41893-021-00693-8 Author-formatted copy Energy and water co-benefits from covering canals with solar panels B. McKuina,b*, A. Zumkehra, J. Taa, R. Balesa, J. H. Viersa, T. Pathaka, J. E. Campbell b* a Sierra Nevada Research Institute, University of California, Merced b Environmental Studies Department, University of California, Santa Cruz * Corresponding authors: [email protected] and [email protected] Solar-power development over canals is an emerging response to the energy-water-food nexus that can result in multiple benefits for water and energy infrastructure. Case studies of over-canal solar photovoltaic (PV) arrays have demonstrated enhanced PV performance due to the cooler microclimate next to the canal. Further, shade from the PV panels has been shown to mitigate evaporation and could mitigate aquatic weed growth. However, the evaporation savings and financial co-benefits have not been quantified across major canal systems. Here we use regional hydrologic and techno-economic simulations of solar PV panels covering California’s 6350 km canal network, which is the world’s largest conveyance system and covers a wide range of climates, insolation rates, and water costs. We find that over-canal solar could reduce annual evaporation by an average of 39 ± 12 thousand m3 per kilometer of canals. Furthermore, the financial benefits from shading the canals outweigh the added costs of cable-support structures required to span canals. The net present value (NPV) of over-canal solar exceeds conventional over-ground solar by 20% to 50%, challenging the convention of leaving canals uncovered and calling into question our understanding of the most economic locations to locate solar power. -
