CCAMP: Open Pacific Coast Study

The Federal Emergency Management Agency (FEMA) is performing  detailed coastal engineering analysis and mapping of the Pacific coast of California in accordance with FEMA’s February 2005 Pacific guidelines for new coastal studies which are included in Appendix D of the Guidelines and Specifications for Flood Hazard Mapping Partners.  Results from the OPC Study will be used to remap the coastal flood risk and wave hazards for the following fifteen California counties:brochure inset_opc.jpg

FEMA’s coastal mapping efforts benefit from new technologies and coastal data contributed by a consortium of Federal and State agencies, academic institutions, and private sector consultants.  The OPC Study will be based on new high-resolution bathymetric and topographic data for the entire California coast acquired from the California Ocean Protection Council and National Oceanic and Atmospheric Administration (NOAA). 

A series of kick-off meetings were conducted in all fifteen coastal counties to initiate the Discovery process.   The goal of the Discovery process is to work closely with communities to better understand the local flood risk and mitigation efforts, and to encourage and support actions taken to increase resilience to flooding. The final kick-off meeting took place in Orange County in January 2012, with a web-based meeting held on January 26, 2012 for community stakeholders who were not able to participate in person.  Another webinar was held on June 6, 2012 to introduce the OPC Study to interested Federal, state, regional, and local entities, as well as non-profit and private sector organizations.

To stay up the date with the OPC Study, sign up for our quarterly bulletin, Coastal Beat that will include schedule updates, technical articles and facts of interest, as well as relevant information as the study progresses.

  • New Increased Flooding Scenario Maps for Bay Area Communities

    ​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

    ​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.
