  • San Mateo County Watershed Data in a GIS
    San Mateo County Watershed Data in a GIS Introduction The San Mateo Countywide Water Pollution Prevention Program (Program) performs Watershed Assessment and Monitoring (WAM) component activities in compliance with its municipal stormwater NPDES permit requirements. In the past, a consistent countywide watershed boundary data layer has not been available to meet Program needs for mapping and analyzing watershed-related data. As a result, the Program has previously utilized the best existing available data sets and/or developed new data to meet the objectives of specific individual projects. For example, creek location and watershed boundary data were developed to characterize imperviousness and channel modifications in seventeen watersheds in San Mateo County (STOPPP 2002). In another example, Program staff compiled existing countywide watershed data and developed new data needed to identify watershed areas considered exempt from Hydromodification Management Plan (HMP) requirements (STOPPP 2005). The Program previously identified two major information gaps in digital watershed boundary data: 1) limited storm drain catchment data were available for urban areas and 2) consistent countywide watershed data layers were not available (STOPPP 2005). Recent development of watershed data in urbanized portions of San Mateo County has provided an opportunity to address these information gaps. This memo describes the methods used by Program staff to create a consistent countywide watershed data layer that includes delineation of storm drain catchments in urban areas. Consistent watershed and creek data set will assist Program staff in watershed characterization and the identification and prioritization of potential future monitoring and watershed assessment activities. Background In 1999, the State of California developed a statewide watershed data layer entitled the California Interagency Watershed Map (Calwater).

  • California's Ground Zero for Sea Level Rise
    SAN MATEO COUNTY: CALIFORNIA’S GROUND ZERO FOR SEA LEVEL RISE Issue Summary Glossary Background Discussion Best Practices Findings Recommendations Request for Responses Methodology Bibliography Appendices Responses ISSUE The San Mateo County Flood and Sea Level Rise Resiliency District (“OneShoreline”) began operating in 2020. It was designed to coordinate countywide efforts to combat the harms of sea level rise caused by climate change. Is OneShoreline on course to adequately address the sea level rise challenge that has been assigned to it, and does it have the support it needs? SUMMARY San Mateo County has been declared the California County most at risk from sea level rise (SLR). Its Bayside communities have billions of dollars of residential and commercial property at risk. Its five wastewater facilities and three airports, including San Francisco International, are all at risk for flooding from the rising sea. Transportation systems, schools, medical facilities, homes, and parks are all at risk. The Pacific coast communities are also vulnerable to flooding and erosion from higher seas.1 Sea level rise is a complex problem with an uncertain timetable that demands ongoing long-term solutions. It requires people to think differently and to truly collaborate. While solutions are still being developed, they will require planning, funding, and collaboration between affected cities, the County, and private entities. OneShoreline was created from the County Flood Control District, has countywide jurisdiction, and focuses on SLR in addition to flooding from creeks. The official name for OneShoreline is the “San Mateo County Flood and Sea Level Rise Resiliency District.” OneShoreline provides expertise in the complex process of designing and building SLR and flood mitigation projects, including guidance through the complex maze of federal and state funding for projects.

  • MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG the SAN ANDREAS FAULT from MUSSEL ROCK to the CENTRAL SANTA CRUZ MOUNTAINS by Earl H
    U.S. DEPARTMENT OF THE INTERIOR U.S. GEOLOGICAL SURVEY MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS, CALIFORNIA By E. H. Pampeyan Menlo Park, California Open-File Report 93-684 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names in this publication is for descriptive purposes and does not imply endorsement by the U.S. Government. 1995 MAPS SHOWING RECENTLY ACTIVE FAULT BREAKS ALONG THE SAN ANDREAS FAULT FROM MUSSEL ROCK TO THE CENTRAL SANTA CRUZ MOUNTAINS by Earl H. Pampeyan PURPOSE OF THIS MAP This map shows the location of lineaments and other geomorphic features interpreted to be the result of historic or relatively recent breaks within the San Andreas Fault Zone. It was compiled primarily to provide information for those concerned with land use and development on or in the fault zone, but it should also be useful in scientific studies of faulting and earthquakes. The lines on the map mark the location of suspected displacements of the ground surface by rupture along the San Andreas Fault. Map users should keep in mind that these lines are primarily guides for locating fault traces on the ground and are not necessarily located with the precision needed for every engineering or land-use project. THE SAN ANDREAS FAULT AND FAULT ZONE The San Andreas Fault Zone is a major structural break in the earth's crust that can be traced for more than 600 miles from the head of the Gulf of California in northern Mexico through western California.

  • Delineation of High Landslide Risk Areas As a Result of Land Cover, Slope, and Geology in San Mateo County, California
    Gaia Stucky de Quay 6th December 2012 Delineation of high landslide risk areas as a result of land cover, slope, and geology in San Mateo County, California Introduction Problem Overview This project attempts to delineate the high-risk areas within San Mateo, California, that are most prone to landslides. The principal method used is based on a ranking system built from 3 key features which include the elevation (used to calculate the slope), rock types, and land cover. The result is a raster with a qualitative ranking, which shows concentration of risk in specific areas. The study shows that softer rocks and vegetation cover have an effect on landslides especially where the elevation is lower. Furthermore, as a result of moderate amount of rainfall, high alluvium concentration near rivers, and large (coastal) human population, the hydrographic flow lines will also be used to assess the risk levels within the county. Background San Mateo has a total area of 1919 km2, of which 1,163.1 km2 (or 61%) is land and 756.1 km2 is water (US Census). The county is bound on the west by the Pacific Ocean, and on the east by the San Francisco Bay. Directly towards the north is San Francisco County and City, and to the south is Santa Clara County. It is often referred to as a peninsula. The Bay Area Corridor is strongly juxtaposed to the agricultural parks and preserves, and undeveloped lands within the rural Coastside. Bay-side watercourses drain the eastern part of the county including San Bruno Creek and Colma Creek.
