California Coastal Analysis and Mapping Project (CCAMP)

Region IX is initiating flood studies/mapping projects in coastal areas as a result of Congressional appropriations for Flood Hazard Mapping under Risk MAP . These efforts will address gaps in required engineering and mapping for high flood risk areas impacted by coastal flooding.  Cumulatively, these flood studies/mapping projects are being referred to as the California Coastal Analysis and Mapping Project (CCAMP).

  • Redelineation: What does it mean for me?

    The California Coastal Analysis and Mapping Project (CCAMP) will update the flood and wave data depicted in the Flood Insurance Study reports and Flood Insurance Rate Maps for nine individual counties in the Bay Area.  Due to the age difference between some effective riverine studies and the new topographic base data used in the CCAMP study, there may be discrepancies in the Special Flood Hazard Area boundaries.  This article explains how FEMA uses the process of redelineation to resolve these discrepancies, and how you can find redelineated areas in your community. 

  • Merging New Coastal Floodplain Mapping with Effective Riverine Flood Zones

    Through the California Coastal Analysis and Mapping Project, (CCAMP) new flood hazard information is being produced for coastal flooding sources throughout California. When such information is developed for a community with a Flood Insurance Rate Map (FIRM), the new information must be carefully integrated into the effective FIRM. The tie in between coastal and riverine flood zones creates seamless hazard mapping and is vital because some floodplains can be inundated by either or both coastal and riverine events.

  • California Coastal Storm History Part Two – Ventura County

    As part of the California Coastal Analysis and Mapping Project (CCAMP) Open Pacific Coast (OPC) Study, FEMA Region IX has developed a 50-year hindcast database of wave conditions along the coast of California.  This information, prepared in partnership with Oceanweather Inc. and the Scripps Institution of Oceanography, will provide the nearshore data inputs required for detailed wave runup and overtopping analyses.  The validation of the extreme wave analysis can be found in the coastal storm history experienced along the various study reaches in each coastal county over the past several decades.  While this coastal storm history is often forgotten, it can provide a useful reminder that extreme coastal flood events have occurred throughout the study area.  This is the second of a three-part series reviewing coastal storm history in various developed and flood-prone coastal areas within the CCAMP OPC Study area.  The focus of the second storm history review shifts to the southern California coast of Ventura County.

  • America’s PrepareAthon! First National Day of Action

    On April 30, 2014 the first national day of action for America’s PrepareAthon! was launched nationwide. Individuals, families, workplaces, schools and organizations across the “Whole Community” came together to practice simple activities to stay safe before, during, and after four types of hazards − floods, wildfires, tornadoes and hurricanes.
