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.

  • FEMA Kicks-Off Sea Level Rise Pilot Study for Coastal Floodplain

    As part the California Coastal Analysis and Mapping Project (CCAMP), FEMA initiated a pilot study to produce non-regulatory future conditions flood maps that account for the effects of sea level rise on coastal flood hazards. FEMA engaged state and federal agencies, and CCAMP stakeholders, to provide input to the study team to ensure coordination with other ongoing efforts. FEMA will apply the results of the preliminary coastal analysis and mapping along the open Pacific coast of San Francisco County as part of a pilot study and develop recommendations for expanding the study more broadly along the West Coast.

  • California Coastal Storm History Part One – Santa Cruz 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.  The 50-year wave database, prepared in partnership with the Scripps Institution of Oceanography, will provide the nearshore data needed to inform the 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 first 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 first storm history review is Santa Cruz County, which is representative of the central California coast.

  • Engaging Stakeholders to Help Communicate Impacts of BW-12

    By engaging with insurance and real estate professionals and other stakeholders to help communicate the impacts of BW-12, local floodplain administrators and other community officials can help property owners reduce their risk and reduce their insurance rate. Reach out to these and other stakeholders to help educate property owners about BW-12 and arm them with the right information. 

  • Elevation Certificates: The Way to Determine Actuarial Flood Risk

    As a result of legislation changes to the National Flood Insurance Program, titled the Biggert-Waters Flood Insurance Reform Act of 2012, an Elevation Certificate (EC) is now needed for most buildings located in a Special Flood Hazard Area. An EC is an official document that records building information, and as such is an important tool to document the structure’s elevation and base flood elevation.
