JULY 2017 BART TO LIVERMORE EXTENSION PROJECT EIR CHAPTER 3 ENVIRONMENTAL ANALYSIS I. BIOLOGICAL RESOURCES I. BIOLOGICAL RESOURCES 1. Introduction This section describes the biological resources setting and existing conditions as they relate to the BART to Livermore Extension Project, discusses the applicable regulations, and assesses the potential impacts to biological resources from construction and operation of the Proposed Project and Alternatives. For the purpose of this analysis, the study area for potential direct impacts includes the collective footprint—the combined footprints of the Proposed Project, Diesel Multiple Unit (DMU) Alternative, and Express Bus/Bus Rapid Transit (BRT) Alternative. In addition, the bus routes and bus infrastructure improvements for the Enhanced Bus Alternative, as well as for the feeder buses for the Proposed Project and other Build Alternatives, which are anticipated to extend along existing streets and within the street rights-of-way (ROWs), are addressed programmatically in this analysis, as described in Chapter 2, Project Description. To produce a comprehensive species list for the study area, the analysis considered sensitive wildlife and plant resources that are documented within 5 miles of the collective footprint. The analysis presented in this section is based on a review of existing information and results from site surveys, which include the following: .

Regional Overview The study area is located within eastern Alameda County within the Dublin, Livermore, and Altamont United States (U.S.) Geological Survey 7.5-minute quadrangles. Topographically, the study area includes a range of elevations, including approximately 330 feet above mean sea level at the Dublin/Pleasanton BART Station (Dublin/Pleasanton Station) and approximately 510 feet above mean sea level at the Cayetano Creek Area. The overall slope and aspect of the study area falls in an east-to-west direction. The study area generally runs parallels to I-580, within highly urbanized landscapes in the cities of Dublin, Pleasanton, and Livermore. However, the study area also extends through agricultural and grazing lands in the vicinity of Isabel South Area and the Cayetano Creek Area. The study area encompasses a variety of land uses that include the existing I-580 transportation corridor and residential, commercial, and industrial uses. Undeveloped areas both north and south of I-580 support agriculture and open space land uses, with annual grassland and ruderal habitats as the most common habitat types north of I-580 in 17 United States.

    Historical Status of Coho Salmon in Streams of the Urbanized San Francisco Estuary, California

    CALIFORNIA FISH AND GAME California Fish and Game 91(4):219-254 2005 HISTORICAL STATUS OF COHO SALMON IN STREAMS OF THE URBANIZED SAN FRANCISCO ESTUARY, CALIFORNIA ROBERT A. LEIDY1 U. S. Environmental Protection Agency 75 Hawthorne Street San Francisco, CA 94105 [email protected] and GORDON BECKER Center for Ecosystem Management and Restoration 4179 Piedmont Avenue, Suite 325 Oakland, CA 94611 [email protected] and BRETT N. HARVEY Graduate Group in Ecology University of California Davis, CA 95616 1Corresponding author ABSTRACT The historical status of coho salmon, Oncorhynchus kisutch, was assessed in 65 watersheds surrounding the San Francisco Estuary, California. We reviewed published literature, unpublished reports, field notes, and specimens housed at museum and university collections and public agency files. In watersheds for which we found historical information for the occurrence of coho salmon, we developed a matrix of five environmental indicators to assess the probability that a stream supported habitat suitable for coho salmon. We found evidence that at least 4 of 65 Estuary watersheds (6%) historically supported coho salmon. A minimum of an additional 11 watersheds (17%) may also have supported coho salmon, but evidence is inconclusive. Coho salmon were last documented from an Estuary stream in the early-to-mid 1980s. Although broadly distributed, the environmental characteristics of streams known historically to contain coho salmon shared several characteristics. In the Estuary, coho salmon typically were members of three-to-six species assemblages of native fishes, including Pacific lamprey, Lampetra tridentata, steelhead, Oncorhynchus mykiss, California roach, Lavinia symmetricus, juvenile Sacramento sucker, Catostomus occidentalis, threespine stickleback, Gasterosteus aculeatus, riffle sculpin, Cottus gulosus, prickly sculpin, Cottus asper, and/or tidewater goby, Eucyclogobius newberryi.

INDEX OF SURFACE-WATER RECORDS PART 11.PPACIFIC SLOPE BASINS IN CALIFORNIA TO SEPTEMBER 30, 1948 EXPLANATION The index lists the stream-flow ana reservoir stations in the Pacific Slope Basins in California for which records have been or are to be pub­ lished for periods prior to September 30, 1948. The stations are listed in downstream order. Tributary streams are indicated by indention. Station names are given in their most recently published forms. Paren­ theses around part of a station name indicate that the enclosed word or words were used in an earlier published name of the station or in a name under which records were published by some agency other than the Geological Survey. The drainage areas, in square miles, are the latest figures published or otherwise available at this time. Drainage areas that were obviously inconsistent with other drainage areas on the same stream have been omitted. Some drainage areas not published by the Geological Survey are listed with an appropriate footnote stating the published source of the figure of drainage area. Under "period of record" breaks of less than a 12-month period are not shown. A dash not followed immediately by a closing date shows that the station was in operation on September 30, 1948.

WSIP Water Supply and System Operations – Setting and Impacts 5.6 Westside Groundwater Basin Resources This section describes the potential effects of the WSIP water supply and system operations and associated WSIP projects on the Westside Groundwater Basin and related water resources, including Lake Merced. The proposed water supply sources under the WSIP include 10 million gallons per day (mgd) of supply every year in all years (including nondrought periods) from implementation of conservation, water recycling, and groundwater supply programs in San Francisco; in addition, the proposed water supply option includes a long-term conjunctive-use program in the San Mateo County portion of the Westside Groundwater Basin, referred to as the South Westside Groundwater Basin, as part of the drought-year water supply for the regional system. The recycled water and groundwater components of this supply would be achieved through two WSIP projects, the Local and Regional Groundwater Projects (SF-2) and the Recycled Water Projects (SF-3), which are described in Chapter 3. The potential effects of the WSIP on the Westside Groundwater Basin and related resources are discussed in the context of ongoing activities in this area occurring among the SFPUC, City of Daly City, California Water Service Company (Cal Water, the municipal water purveyor to South San Francisco), and the City of San Bruno. 5.6.1 Setting 5.6.1.1 Westside Groundwater Basin The Westside Groundwater Basin extends from San Francisco south to San Mateo County (Figure 5.6-1). With an area of about 45 square miles, this groundwater basin is the largest in San Francisco.

ØSteelhead (up to 30”) have been caught in the Arroyos here up until the 1960s. ØThey currently do not migrate through the Arroyos because of - barriers in lower Alameda Creek and the Arroyos - inadequate stream flows allowed by Zone 7 Water Agency. ØBiologists have determined that steelhead could spawn in the upper gorge of Arroyo Mocho where native trout already live ØSmolts (juveniles) can survive in existing deep spring-fed pools in the Mocho gorge during our hot summers ØSmolts (1-2 yrs old) migrate downstream and adults upstream to spawn and back during the high flows around storm events. Adults can travel 1 mile/hour! Historical evidence of migration Steelhead caught in Alameda Creek in 1961 Livermore Herald: April 9, 1910 A 30” trout must be a steelhead!

    Foothill Yellow-Legged Frog Comments

    The Center for Biological Diversity submits the following information for the status review of the foothill yellow-legged frog (Rana boylii) (Docket #FWS-R8-ES-2015-0050), including substantial new information regarding the species' biology, population structure (including potential Distinct Population Segments of the species), historical and recent distribution and status, population trends, documented range contraction, habitat requirements, threats to the species and its habitat, disease, and the potential effects of climate change on the species and its habitat. The foothill yellow-legged frog has experienced extensive population declines throughout its range and a significant range contraction. Multiple threats continue unabated throughout much of the species’ remaining range, including impacts from dams, water development, water diversions, timber harvest, mining, marijuana cultivation, livestock grazing, roads and urbanization, recreation, climate change and UV-radiation, pollution, invasive species and disease. The species warrants listing as threatened under the Endangered Species Act.
