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.

  • The Summary of Map Actions (SOMA) Report: SOMAs Deciphered

    Many community officials and floodplain managers are called upon to review a Summary of Map Actions (SOMA) report, but how familiar are you with this document, and the process of developing it? Did you know that the ability to revise or amend effective Flood Insurance Rate Map (FIRM) panels is always available? Revisions and amendments to flood hazard information may be accomplished through FEMA’s Letter of Map Change (LOMC) process, without having to re-publish the FIRM. When a Flood Insurance Study (FIS) update or restudy requires a revised FIRM panel to be re-published, the existing LOMCs that applied to the old effective FIRM panels are superseded by the newly effective FIRM panels, and LOMCs that have remained valid are revalidated. As part of a map revision, FEMA publishes a Preliminary and Final SOMA report. The SOMA records a complete list of all previously issued LOMCs, and their valid or superseded status, for each community affected by revised FIRM panels. The SOMA assists community officials in maintaining the most up-to-date information on their community’s FIRMs. (Read more…)

  • Flood Insurance Rate Maps and Flood Insurance Studies: From Preliminary to Effective

    ​FEMA flood hazard maps inform communities about the local flood risk. Flood hazard mapping is an important part of the National Flood Insurance Program (NFIP), as FEMA regulatory products provide the basis for regulating development and determining flood insurance requirements under the NFIP regulations. FEMA maintains and updates regulatory flood hazard data through Flood Insurance Rate Maps (FIRMs) and Flood Insurance Study (FIS) reports.

     
    Following the data acquisition and data development phases of the flood insurance study process, FEMA distributes one set of the preliminary FIRM panels, the preliminary FIS Report, and the preliminary Summary of Map Actions (SOMA) to community CEOs. FEMA also posts PDF versions of the preliminary FIRM panels and FIS Report, as well as the DFIRM database containing the GIS shapefiles, to the Map Service Center (MSC), where they are available for public download. (The preliminary FIRM panels and the preliminary DFIRM database are archived on the MSC when the panels, FIS report, and database become effective.) The steps that follow, referred to as the post-preliminary process, include the public comment and appeal period, community and public meetings, the Letter of Final Determination, and community adoption/compliance requirements. 
     
    From July 2015 through November 2015, FEMA distributed preliminary data to ten coastal counties as part of the Open Pacific Coast Study and three counties as part of the San Francisco Bay Area Coastal Study.
