The Public Health Emergency Preparedness Program has created various interactive maps to aid public health officials and response partners in the planning, response, and recovery phases of an emergency. These maps may also provide helpful information to the public.
Social Vulnerability Index (SVI) map: SVI - developed by the Center for Disease Control and Prevention's Agency for Toxic Substance and Disease Registry (ATSDR) - uses U.S. Census data to determine the social vulnerability of every Census tract to help public health officials and emergency response partners identify and map the communities that will most likely need support before, during, and after a hazardous event. The SVI ranks each tract on 16 social factors, four related themes, and provides an overall ranking. This map provides information related to the 16 social factors, maps the four SVI themes and overall ranking.
Flood Hazard Areas map: Floods can happen anywhere it rains. The 100-year flood plain is an area with a 1 in 100, or 1%, chance of flooding each year. The 500-year flood plain is an area with a 1 in 500, or 0.2%, chance of flooding each year. This map shows the areas in Sacramento County with a 1% and 0.2% annual chance of flooding.
The maps are interactive.
