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 role of beach nourishment in coastal flood protection and its consideration in Flood Insurance Studies

    Beach nourishment is one the most common forms of shore protection, and is favored because it has a relatively low impact on the surrounding areas and directly addresses the need to replenish a beach’s sand volume. There are numerous effective beach nourishment strategies, and to address those options, FEMA developed guidelines on assessing projects for their ability to provide flood protection measures. In order to be considered in the flood mapping study, the nourishment project must be large enough to affect the base flood hazard and the community must be able to show a commitment to funding the ongoing maintenance needs of the project. This article specifically examines the role of beach nourishment in coastal flood protection and its consideration in the California Coastal Analysis and Mapping Project Open Pacific Coast (CCAMP OPC) Study.

  • FEMA increases community access to draft floodplain mapping data

    At the request of several San Francisco Bay Area communities, FEMA is providing access to draft Flood Insurance Rate Maps (FIRM) (a.k.a. work maps) through the FEMA online GeoPlatform. FEMA’s GeoPlatform is an ArcGIS online mapping application that makes it easy to share data seamlessly across the internet.  After the Flood Risk Review meeting, the draft floodplain maps are uploaded to the GeoPlatform where communities can continue to access the draft work map data, and use it as “best available information” until the Preliminary Flood Insurance Rate Maps are officially released.

  • Coastal Storm History in San Diego County

    The 20th century  legacy of severe Pacific winter storms that caused coastal damages throughout the century, including beach/bluff erosion, seawall damages, and flooding from wave overtopping have been  well-documented in reports of the National Research Council (1984), Gary Griggs (et al. 2005), and others.  This coastal storm history is too often forgotten when facing new threats. When that history should serve as a stark reminder that extreme coastal flood events are a fact of life along the southern California coast.  This article discusses storm damages during the 1982-83 and 1997-98 El Niño winters in San Diego County, and provides a reminder of the high damage risk that the oceanfront built environments can expect to experience in any given year.
