  • Project Background
    CHAPTER 2 Project Background This chapter provides an overview of the existing Los Vaqueros Reservoir facilities and operations, a history of the expansion project, a description of current Delta water supply facilities and operations, and a summary of ongoing planning and regulatory processes related to the Delta. This information provides context for understanding how expansion of the Los Vaqueros Reservoir could achieve the objectives outlined in Chapter 1, Purpose and Need. 2.1 Existing Los Vaqueros Reservoir The Los Vaqueros Reservoir is a 100 thousand-acre-foot (TAF) offstream storage reservoir in southeastern Contra Costa County owned and operated by the Contra Costa Water District (CCWD)1. The reservoir is operated to improve water quality and provide emergency storage for CCWD’s 550,000 customers in central and eastern Contra Costa County. CCWD completed the reservoir and associated facilities (including a new intake on Old River near State Route 4 (SR 4)) in 1997. The reservoir facilities are operated as an integrated system with the Contra Costa Canal and Rock Slough Intake built as part of the federal Central Valley Project (CVP) in the 1940s. These facilities are described in more detail in the following sections. CCWD also owns the Los Vaqueros Watershed (watershed) which covers about 20,000 acres. The watershed lands are managed for water quality, conservation, and recovery of special-status species and their habitats, and recreation. The reservoir also provides flood control benefits on Kellogg Creek.2 The CCWD service area, watershed lands, and major untreated water facilities are shown on Figure 2-1. More recently, CCWD has constructed or is constructing two facilities that will be operated integrally with the reservoir: the CCWD-East Bay Municipal Utility District (EBMUD) Intertie, completed in 2007, and a new intake on Victoria Canal known as the Alternative Intake Project (AIP), currently under construction.

  • Los Vaqueros Reservoir Expansion Project Draft Supplement to The
    CHAPTER 5 Climate Change This chapter provides an overview of the climate change scenarios developed by the California Water Commission (CWC) and how a changed climate may change the long-term impacts and benefits of the Phase 2 Expansion. An analysis of how each alternative may change greenhouse gas emissions can be found in the Air Quality Section 4.10. The CWC requires that applicants evaluate their storage project under two specific climate change scenarios for the years 2030 and 2070 (Section 6004 of Water Storage Investment Program). Consideration of climate change is required in the quantification of public benefits of water storage projects to comply with Executive Order B-30-15 (2015) and Assembly Bill 1482 (2015), which require state agencies to account for climate change in project planning and investment decisions. Two CalSim II models with projected future changes in rainfall, runoff, sea-level rise, SWP and CVP operations for the years 2030 and 2070 were developed by the CWC and are used to evaluate the Phase 2 Expansion benefits and impacts. Other aspects of climate change such as changes in atmospheric CO2, humidity, wind and solar radiation are not explicitly included in the CalSim II models but could affect environmental conditions. 5.1 Overview of Climate Change Modeling CWC staff worked with DWR’s Climate Change Technical Advisory Group (CCTAG) to select 20 scenario-model combinations that are most appropriate for California water resource planning and analysis (DWR, 2015). The 20 climate scenario-model combinations were composed of 10 global climate models (GCMs) run with two emission scenarios, one optimistic (RCP 4.5) and one pessimistic (RCP 8.5).

  • I: Los Vaqueros Expansion Draft EIS/EIR
    APPENDIX D Plant Community and Special-status Species Descriptions Plant Communities in the Project Area The Los Vaqueros Watershed (Watershed) encompasses 18,535 acres of land and includes 20 distinct vegetation series (ESA, 2004; Sawyer and Keeler-Wolf, 1995). The following subsections describe plant communities both within and outside the Watershed. The analysis presents NCCP Plant Community / Habitat Type designations with Sawyer and Keeler-Wolf equivalent vegetation series in parentheses. Section 4.6 Biological Resources, Table 4.6-1, and Figure 4.6-2 of the Draft EIS/EIR describe the distribution and extent of these plant communities in the Watershed. Lacustrine (Open Water/Tidal Perennial Aquatic) Description Lacustrine habitat includes permanent deep-water bodies that do not support emergent vegetation and are not subject to tidal exchange, and tidal perennial aquatic that includes deepwater aquatic (greater than 3 meters deep), shallow aquatic (less than or equal to 3 meters deep), and unvegetated intertidal zones of estuarine bays, river channels, and sloughs (CALFED Bay-Delta Program, 2000a). Such features include lakes, ponds, oxbows, gravel pits, and flooded islands. Lacustrine habitat includes areas defined as tidal and nontidal perennial aquatic habitat. Submerged and floating aquatic plant species associated with lacustrine habitats include water lilies, pondweed, duckweed, and plankton. This habitat type is commonly used by a wide variety of birds, mammals, reptiles, and amphibians for reproduction, food, water, and cover (CALFED Bay-Delta Program, 2000a). Historical and Current Distribution Lacustrine habitat occurs in some low-lying areas of the Bay-Delta estuary. Historically, most wetlands in the Bay-Delta estuary were subject to tidal influence, and nontidal perennial aquatic habitats were uncommon.

  • Rancho to Reservoir Chapter 4 (PDF)
    148 From Rancho to Reservoir CHAPTER 4 FULL CIRCLE: LOS VAQUEROS FROM 1929 TO THE PRESENT Within the first decades of the 20th century, agricultural land at Los Vaqueros had become marginal. Without irrigation it could not support specialty crops or orchards, and the hilly terrain precluded widespread mechanization. The subsistence-based mixed farms that had developed on the Vasco and in the Black Hills were beginning to be anachronistic, and it became clear that the most efficient use of the land was for grazing. Gradually, many of the Los Vaqueros farm families packed up their belongings and moved on—some to nearby towns, and some to ranches of their own. On the Vasco, tenant arrangements under Mary Crocker and Kate Dillon had been gener- ous, so attrition was slower, but change was inevitable in the volatile economy of the first half of the 20th century. By the late 1980s, when the Contra Costa Water District began acquiring the lands of the watershed, much of the old rancho and adjoining property was once more sparsely settled and given over to livestock grazing. LAND SALES The nationwide economic depression that began with the stock-market crash of 1929 had a grave effect on agriculture in California. Crop prices fell dramatically, and cereal growers needed at least 400 harvested acres to support a family—double the amount of land they had needed at the beginning of the century. New Deal crop-subsidy programs inadvertently favored large farms over small interests by basing awards on the absolute size of the operation as opposed to propor- tional needs of families.

  • CHAPTER 3 Description of Project Alternatives
    CHAPTER 3 Description of Project Alternatives 3.1 Introduction 3.1.1 Chapter Overview This chapter describes the alternatives for the proposed Los Vaqueros Reservoir Expansion Project, including the four action alternatives and the No Project/No Action Alternative. The four action alternatives are summarized in Section 3.1.2 and described in more detail in Section 3.4. The chapter is organized as follows: • Section 3.2 describes the process that was used to develop the action alternatives, the process that was used to screen the eight action alternatives that were developed, and the four alternatives that were eliminated from further evaluation. • Section 3.3 provides a detailed description of the No Project/No Action Alternative. • Section 3.4 provides a detailed description of the four action alternatives. • Section 3.5 describes the proposed facilities under the four action alternatives in terms of location, site layout, and chief design and operational characteristics. • Section 3.6 describes the construction activities that would occur in the Proposed Project (all four action alternatives). • Section 3.7 describes the approvals and permits that would be required to implement the Proposed Project. 3.1.2 Summary of Action Alternatives Evaluated in This Draft EIS/EIR This section contains a summary of the four action alternatives. The action alternatives represent different combinations of facility options and water system operations for expanding the Los Vaqueros Reservoir (reservoir), as well as associated water conveyance. The facility options are distinguished by the amount of expansion of the reservoir capacity (i.e., from the existing 100 thousand acre-foot (TAF) to 160 TAF or to 275 TAF) and whether a new conveyance pipeline connecting the expanded reservoir to the South Bay water agencies via the State Water Project (SWP) Bethany Reservoir at the South Bay Pumping Plant (South Bay Los Vaqueros Reservoir Expansion Project 3-1 February 2009 Draft EIS/EIR Los Vaqueros Reservoir Expansion Project Connection) is included in the project.
