California Coastal Analysis and Mapping Project (CCAMP)

​FEMA has created new non-regulatory mapping products for all nine San Francisco Bay Area counties that depict increased coastal flooding scenarios. The Increased Flooding Scenario Maps complement the National Flood Insurance Program regulatory products, i.e. the Flood Insurance Rate Maps (FIRMs), Flood Insurance Study reports and GIS databases.

These mapping products are available now and utilize the most up-to-date data based on FEMA’s San Francisco Bay Area Coastal Study. They provide additional information on how the 1-percent-annual-chance (i.e. 100-year) coastal floodplain may change with a 1-foot, 2-foot, and 3-foot increase in flood levels.

​Living with levees is a shared responsibility. It is important for both levee owners, and those who live and work near levees, to understand the risks associated with levees. As part of its California Coastal Analysis and Mapping Project, FEMA Region IX is evaluating protection levels of previously accredited coastal levees using updated flood hazard data and communicating current risk information to levee owners.
