Improvements included channel widening improvements are completed. and raising the levees to increase the creek’s capacity to carry storm flows and reduce flood risk. East of Lower Penitencia Creek, Valley Water completed the About the project Lower and Upper Berryessa Creek flood protection projects to provide a 100-year storm level of service, with work on Calera The Lower Penitencia Creek Improvements Project extends Creek planned for summer 2021.

This project would prevent the increased water flow from overtopping Lower Penitencia Creek banks, causing a flood. This project’s completion is necessary to maintain the existing Federal Emergency Management Agency (FEMA) accreditation along the east levee located between California Circle and Berryessa Creek. The current accreditation is for a 100-year flood event and level of protection. When improvements are completed for the Lower Penitencia and Berryessa Creek projects, Valley Water will update the FEMA flood insurance maps accordingly. Project objectives The Lower Penitencia Creek Improvement Project objectives are to: • Safely carry and prevent the overtopping of Lower Penitencia Creek from the increased Berryessa Creek storm flows. • Reduce flood risks by aligning the creek elevations where Coyote and Berryessa creeks meet. • Continue a 100-year level of flood protection to the surrounding homes, businesses, and public facilities. • Minimize the need for seasonal maintenance. • Maintain existing Federal Emergency Management Agency (FEMA) accreditation along the east levee located between California Circle and Berryessa Creek and ensure View from the north side levee that faces upstream of California Circle bridge. improvements meet certification requirements.

Powers & Associates FROM: Caitlin Gilmore, PE JOB#: DPOW.100.18 SUBJECT: The San Jose Flea Market Mixed Use Development Flooding and Drainage Evaluation Updated INTRODUCTION This memorandum is an update to the previous analysis completed in September of 2005. David J Powers is preparing an EIR to develop 52 acres of residential units and office space with two new bridge crossings to the south side of the previously analyzed Flea Market site, south of Berryessa Road, east of Coyote Creek and adjacent to the new VTA/BART line. In addition to focusing on the south side of Berryessa Road, this update includes several changes which have occurred in the watershed; namely the completion of the BART/VTA track guideway and Berryessa Station, the improvements to Upper Penitencia Creek with bridge replacements and studies of the watershed completed on behalf of VTA and the Santa Clara Valley Water District. In addition, the phase of the Flea Market development on the north side of Berryessa Road is under construction. The objective of this study is to describe the existing flood and drainage conditions at the proposed San Jose Flea Market mixed use development project (north and south), the potential project constraints, and potential impacts of the proposed project. The project area includes Upper Penitencia Creek and is adjacent to Coyote Creek.

    Chapter 2 Land Use and Covered Activities 2.1 Introduction This chapter examines existing land use conditions and land use plans in the study area, and describes activities covered under the Plan. The land use component of this chapter provides an overview of the major land use and open space management agencies operating within the study area and provides a brief description of each agency’s mission and jurisdiction. The description of land use provides the necessary context for the covered activities upon which the impact analysis (Chapter 4) is based. This chapter provides history and context for future development in the study area, reviews existing land-use conditions and relevant land use plans; presents the criteria used to determine land use categories for the Plan; discusses significant existing open spaces in the study area and open space type classification; and describes the projects and activities within the permit area that will be covered under the incidental take permits. 2.2 Land Use and Jurisdictions 2.2.1 Existing Conditions Santa Clara County encompasses 835,449 acres (1,305 square miles), 519,506 acres (810 square miles, or 62% of the County) of which are included in the study area of this Plan. The fertile Santa Clara Valley (Valley) runs the entire length of the County from north to south, ringed by the rolling hills of the Diablo Range on the east and the Santa Cruz Mountains on the west. Salt marshes, tidal wetlands, and mostly abandoned salt ponds lie in the northern part of the County, adjacent to San Francisco Bay (County of Santa Clara 2006a) (see Figure 1-1 for the regional location of the Plan study area).

It presents an initial vision for how ecological elements could contribute to flood management objectives, based on a broad-scale analysis, two one-day workshops of local and regional experts, and a series of charrettes held by the Santa Clara Valley Water District. This landscape vision is not intended to be implemented as is, but rather adapted and applied through future projects and analysis.

  • Water Resources, Water Quality, and Floodplains
    Silicon Valley Rapid Transit Corridor Final EIR 4.18 WATER RESOURCES, WATER QUALITY, AND FLOODPLAINS 4.18.1 INTRODUCTION This section describes the regulatory setting and existing conditions applicable to water resources, water quality, and floodplains in the SVRTC study area. It evaluates the extent to which the Baseline Alternative and BART Alternative would result in impacts to these resource areas and identifies mitigation measures to avoid or reduce these impacts. 4.18.2 EXISTING CONDITIONS This section describes the existing conditions of groundwater resources, surface water resources, and floodplains in the SVRTC study area as the basis for determining impacts to water quality and supply, flood risk, or encroachment into the floodplain. Key sources of information consulted on existing hydrologic conditions included the following: • The current Fremont General Plan (City of Fremont 1991); • The California State Water Resources Control Board’s listing of water bodies identified as having limited water quality (California State Water Resources Control Board 2003); • The most recent Flood Insurance Rate Maps (FIRMs) for the region that includes the SVRTC project area (Federal Emergency Management Agency 2000); • BART Warm Springs Extension Draft Environmental Impact Report (San Francisco Bay Area Rapid Transit District 1991a); • The Silicon Valley Rapid Transit Corridor Location Hydraulic Study Technical Report (Earth Tech, Inc. 2003). 4.18.2.1 Weather and Climate The San Francisco Bay Area, like much of California’s central coast, enjoys a Mediterranean climate characterized by mild, wet winters and warm summers. Moderated by proximity to San Francisco Bay and the ocean, temperatures are seldom below freezing. Summer weather is dominated by sea breezes caused by differential heating between the interior valleys and the coast, while winter weather is dominated by storms from the northern Pacific Ocean that produce the majority of the region’s annual rainfall.

Center for Ecosystem Management and Restoration SANTA CLARA COUNTY Coyote Creek Watershed Coyote Creek originates on the slopes of Mount Sizer near Henry Coe State Park and flows generally south and west to the Santa Clara Valley. Near the site of Coyote Reservoir, the creek turns to flow north to enter the southern San Francisco Estuary near Dixon Landing Road. The main stem consists of approximately 42 miles of stream channel, and the creek has approximately ten primary tributaries. The watershed area is about 354 square miles. Coyote Creek Snyder documented the occurrence of Salmo irideus (O. mykiss) from collections likely made in 1898 from two locations in lower Coyote Creek (Snyder 1905). He described O. mykiss near the mouth and near the city of San Jose, indicating that the lower creek historically contained suitable habitat. A museum O. mykiss specimen from an unknown Coyote Creek location was collected by Synder in 1898, and is designated “Santa Clara Co., Cal.” (Snyder 1898). Oncorhynchus mykiss was collected from upper Coyote Creek in the canyon east of the Town of Madrone (located within present day Morgan Hill) in 1936 (Fry 1936).
