The Hazard Viewer is a one-of-its-kind interactive map of regional hazards, curated from the most relevant, current maps for the nine-county Bay Area. It brings together the best set of mapping resources that exist in the region for each hazard.
Get more details about the Hazard Viewer.
An easy-to-use tool for contextualizing local risk at the household-, neighborhood-, jurisdiction- and county-level, the Hazard Viewer includes layers for viewing:
- Historic wildfire perimeters
- Fire hazard severity zones
- Tsunami evacuation zones
- Federal Emergency Management Agency (FEMA) flood hazard
- Landslide hazard (rainfall-induced)
- Earthquake fault zones
- Probabilistic earthquake shaking hazard
- Earthquake liquefaction susceptibility
- Earthquake deaggregation
- Earthquake shaking scenario maps for 16 local faults and fault segments
Sea level rise map viewers are available through the BCDC Adapting to Rising Tides program (see below).
For more granular visualization and analysis, including the preparation of risk reports or custom maps, all layers of the Hazard Viewer are built on data sets that can be downloaded from the Hazard Viewer’s “About” description for each section, or from the Hazard Viewer Open Data Page for use on a GIS-based application.
The Adapting to Rising Tides (ART) Bay Shoreline Flood Explorer and associated analyses provide a regional-scale illustration of bay shoreline flooding due to specific sea level rise and storm surge scenarios.
This resource includes a mapping tool and downloadable data sets. These resources are intended to improve sea level rise awareness and preparedness.
This resource focuses on flooding inside the San Francisco Bay and does not include the Pacific coast west of the Golden Gate Bridge. The separate East Contra Costa Shoreline Flood Explorer provides mapping for Eastern Contra Costa County.
It is a product of The Bay Conservation Development Commission Adapting to Rising Tides program.
This resource helps Delta communities in Contra Costa County prepare for the impacts of current and future flooding due to sea level rise and storm events.
Learn about causes of flooding, explore maps of flood risk along our shoreline and download data for further analysis.
These maps increase understanding of what could be at risk without future planning and adaptation, helping Delta communities, governments and businesses to drive action.
