  • Pt. Isabel-Stege Area
    Tales of the Bay Shore -- Pt. Isabel-Stege area Geology: The “bones” of the shoreline from Albany to Richmond are a sliver of ancient, alien sea floor, caught on the edge of North America as it overrode the Pacific. Fleming Point (site of today’s racetrack), Albany Hill, Pt. Isabel, Brooks Island, scattered hillocks inland, the hills at Pt Richmond, and the hills across the San Pablo Strait (spanned by the Richmond Bridge) all are part of this Novato Terrane. Erosion and uplift eventually left their hard rock as hilltops in a valley. Still later – only about 5000 years ago -- rising seas from the melting glaciers of our last Ice Age flooded the valley, forming today’s San Francisco Bay. The “alien” hilltops became islands, peninsulas linked to shore by marsh, or isolated dome-like “turtlebacks.” Left: Portion of 1911 map of SF Bay showing many Native American sites near Pt. Isabel and Stege. Right: 1853 U.S. Coastal Survey map showing N. end of Albany Hill, Cerrito Creek, Pt. Isabel, and marshes/ to North. Native Americans: Native Americans would have watched the slow rise of today’s Bay. When Europeans reached North America, the East Bay was the home of Huchiun Ohlone peoples. Living in groups generally of fewer than 100 people, they moved seasonally amid rich and varied resources, gathering, hunting, fishing, and encouraging useful plants with pruning and burning. They made reed boats, baskets, nets, traps, mortars, and a wide variety of implements and decorations. Along the shellfish-rich shoreline they gradually built up substantial hills of debris – shell mounds -- that kept them above floods and served as multipurpose homesites, burial sites, refuse dumps, and more.

  • Chapter 4.9 Land Use and Planning
    Section 4.9 Land Use and Planning 4.9 LAND USE AND PLANNING 4.9.1 Introduction This section evaluates the potential land use and planning impacts of development under the 2014 LRDP. The planned 2014 LRDP land uses are described and assessed for potential conflicts with existing RBC site and surrounding land uses and land use plans. Public and agency NOP comments related to land use and planning are summarized below: The EIR should consider proposed new building heights and massing in terms of compatibility with surrounding uses. The EIR should consider 2014 LRDP compatibility with the Eastshore State Park General Plan goals and policies. The 2014 LRDP should conform to local zoning and approved local land use policies to the maximum extent feasible. These comments are considered in the analysis below. 4.9.2 Environmental Setting Project Site The approximately 134-acre RBC site is in the City of Richmond, approximately 5 miles northwest of the UC Berkeley campus and the LBNL site in Berkeley (see Figure 3-1). The City of Richmond is in Contra Costa County. The RBC site is bounded on the west by a PG&E service station, on the northwest by Regatta Boulevard, on the northeast by Meade Street, on the east by South 46th Street, and on the south by the San Francisco Bay. I-580 runs parallel to Meade Street along the northeastern boundary of the RBC site. Existing On-Site Land Uses The RBC site has been the location of a variety of industrial enterprises dating back to the mid- 19th century.

  • Pt. Isabel Regional Shoreline Closed Oct. 27 for Trail Repair
    > East Bay Regional Park District | Embrace Life! > About Us > News > Pt. Isabel Regional Shoreline Closed Oct. 27 for Trail Repair News Pt. Isabel Regional Shoreline Closed Oct. 27 for Trail Repair By EBRPD Public Affairs October 9, 2015 The East Bay Regional Park District will CLOSE Pt. Isabel Regional Shoreline from 5 a.m. to 10 p.m. Tuesday, Oct. 27, for slurry-seal repair work on the paved trails. No entry into the park will be allowed from either the Isabel Street side or the Rydin Road side. The Marina Bay-to-Point Isabel Trail from the bridge at Meeker Slough to the end of Rydin Road will be closed; there will be no access to North Point Isabel. The trail from the end of Central Avenue to Isabel Street will also be closed. In addition, Mudpuppy’s Dog Wash and the Sit and Stay Café will be closed for the day. The closure is to allow work crews to slurry seal the asphalt, which will help smooth out and protect the trail and reduce the need for replacement. The material is wet, very sticky, smelly and difficult to remove. We do not want people or dogs on it until it is completely dry. The project will take all day, including drying time. North Point Isabel trails will not be slurry sealed. That area will be closed because the trails that lead to it are being slurry sealed and there will not be any way to access it. The asphalt there needs replacement, which is a bigger job and will be done at another time.

  • California Clapper Rail ( Rallus Longirostris Obsoletus ) TE-807078-10
    2009 Annual Report: California Clapper Rail ( Rallus longirostris obsoletus ) TE-807078-10 Submitted to U.S. Fish and Wildlife Service, Sacramento December 16, 2009 Submitted by PRBO Conservation Science Leonard Liu 1, Julian Wood 1, and Mark Herzog 1 1PRBO Conservation Science, 3820 Cypress Drive #11, Petaluma, CA 94954 Contact: [email protected] Introduction The California Clapper Rail ( Rallus longirostris obsoletus ) is one of the most endangered species in California. The species is dependent on tidal wetlands, which have decreased over 75% from the historical extent in San Francisco Bay. A complete survey of its population and distribution within the San Francisco Bay Estuary was begun in 2005. In 2009, PRBO Conservation Science (PRBO) completed the fifth year of field work designed to provide an Estuary-wide abundance estimate and examine the temporal and spatial patterns in California Clapper Rail populations. Field work was performed in collaboration with partners conducting call-count surveys at complementary wetlands (Avocet Research Associates [ARA], California Department of Fish and Game, California Coastal Conservancy’s Invasive Spartina Project [ISP], and U.S. Fish and Wildlife Service). This report details PRBO’s California Clapper Rail surveys in 2009 under U.S. Fish and Wildlife service permit TE-807078-10. A more detailed report synthesizing 2009 and 2010 survey results from PRBO and its partners is forthcoming. Methods Call-count surveys were initiated January 15 and continued until May 6. All sites (Table 1) were surveyed 3 times by experienced permitted biologists using a point transect method, with 10 minutes per listening station. Listening stations primarily were located at marsh edges, levees bordering and within marshes, boardwalks, boat-accessible channels within the marsh, and in the case of 6 marshes in the North Bay, foot access within the marsh.

  • Bay Trail Richmond New Year 2021 Report
    Bay Trail Richmond New Year 2021 Report This has been an extraordinary year for the San Francisco Bay Trail in Richmond! The City of Richmond (City) completed the long-awaited Bay Trail connection with Point Pinole Regional Shoreline, and over $4 million in grant funds were secured by the City and East Bay Regional Park District (EBRPD) to construct new and improved sections of Bay Trail. The Bay Trail’s popularity soared as an excellent place to refresh the mind and exercise the body with adequate width for social distancing. This 22nd New Year report by TRAC, the Trails for Richmond Action Committee, describes progress during 2020 toward closing gaps and improving existing sections of the Bay Trail. The map on the last page of this report shows trail completed and gaps remaining. Richmond has 36 miles of Bay Trail in place, representing 10% of the existing 352 miles of this planned 500-mile walking and cycling path encircling San Francisco and San Pablo Bays. However, 6.0 miles of gaps remain in Richmond, despite having more Bay Trail completed than any other city in the Bay Area. Stay healthy and be well. See you on the Bay Trail! POINT PINOLE CONNECTED WITH THE BAY TRAIL The City completed construction of a two-way, multi-use trail east of Goodick Avenue between the Richmond Parkway Bay Trail and Dotson Family Marsh Staging Area. This project was funded by a $976,000 grant of Measure J gasoline tax revenues from Contra Costa Transportation Authority and $130,000 from the Bay Trail Project at the Association of Bay Area Governments.

  • Chapter 4.8 Hydrology and Water Quality
    Section 4.8 Hydrology and Water Quality 4.8 HYDROLOGY AND WATER QUALITY 4.8.1 Introduction This section presents existing RBC site hydrologic and water quality conditions and analyzes the potential for development under the proposed 2014 LRDP to affect those resources. This analysis is based on information summarized in the Current Conditions Report (Tetra Tech 2008), more recent Tetra Tech reports including the 2012 Groundwater Results Technical Memorandum, and various publicly available technical studies. The hydrology and water quality discussion includes a description of the regulatory environment; stormwater drainage features; flooding potential; groundwater hydrology, including groundwater depth and flow; surface water and groundwater interaction; and current water quality. Existing RBC site conditions are described in terms of historical and current site uses. Public and agency NOP comments related to hydrology and water quality concerned restoration of the Meeker Ditch to a natural state, existing site contamination, completion of site remediation, increasing runoff to Western Stege Marsh, and assessing and planning for sea-level rise and storm surges. 4.8.2 Environmental Setting The RBC site is approximately 134 acres and consists of upland areas developed with buildings that are used for academic teaching and research activities and spaces leased by private entities, areas of coastal grasslands, a tidal salt marsh (known as the Western Stege Marsh), and a transition zone between the upland areas and the marsh. Grasslands occur in a number of meadows on the RBC site. The parcel west of Regatta Boulevard is fully developed. Surface Water Runoff on the RFS portion of the RBC site currently flows from north to south by way of sheet flow, open swales, culverts, and storm drains.
