Name: Social Vulnerability 12-inches

Display Field: Name

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The community vulnerability shapefile contains 4 categories of information:Social Vulnerability Indicators: Certain socioeconomic characteristics may reduce ability to prepare for, respond to, or recover from a hazard event. Census block groups with high concentrations (relative to the 9 county Bay Area) of these characteristics are flagged as socially vulnerable, with each block group assigned a rank of highest, high, moderate, and low. Data is from American Community Survey 2016 5-year estimates.Contamination Vulnerability Indicators: The presence of contaminated lands and water raises health and environmental justice concerns, which worsen with flooding and sea level rise. A rank of highest, high, moderate, and lower for the severity of contamination in each block group was calculated using data compiled by CalEPA Office of Environmental Health Hazard Assessment (OEHHA) for use in CalEnviroScreen 3.0.Residential Exposure to Sea Level Rise: Calculated by intersecting Metropolitan Transportation Commission 2010 residential parcel datawith 2017 ART Bay Area Sea Level Rise and Shoreline Analysis data, FEMA 100 and 500 year flood zone data, and San Francisco 100 year precipitation data to generate percent residential exposure at each water level by block group. The number of residential units exposed in each block group was divided by total residential units per block group.Complementary Community Vulnerability Screening Tools: Many screening approaches exist to characterize disadvantaged or vulnerable communities. Often in the Bay Area, different designations of disadvantaged/vulnerable communitites are located in the same area. It is recommended to use the ART approach in combination with other complementary tools and designations.The following are included in this shapefile as fields for cross-referecing: CalEnviroScreen 3.0 total score, Metropolitan Transportation Commission Community of Concerndesignation, UC Berkeley Displacement and Gentrification Typologies.
