FEMA Kicks-Off Sea Level Rise Pilot Study for Coastal Floodplain
Vince Geronimo, PE, CFM, AECOM
The Department of Homeland Security’s Federal Emergency Management Agency (FEMA) is developing updated flood hazard data for the populated coast of the U.S. under the Risk Mapping, Assessment, and Planning (Risk MAP) program.  FEMA Region IX initiated the California Coastal Analysis and Mapping Project (CCAMP) Open Pacific Coast (OPC) Study in 2010 to analyze the existing coastal high hazard areas for the entire California coast in order to update Flood Insurance Rate Maps and to provide resources for communities to increase public awareness and encourage mitigation actions that reduce coastal flood risk. 
 
The CCAMP OPC Study preliminary coastal analysis and mapping results will be used as part of a pilot study to analyze future coastal flood risks that takes into account Sea Level Rise (SLR) and the associated changes to wave hazards, depth and extent of inundation, and storm induced erosion.  FEMA selected the nine mile segment of the open Pacific coast at the city and county of San Francisco west of the Golden Gate Bridge for the pilot study location.  Results of the analysis will be used to develop future conditions flood hazard data layers for use in non-regulatory Risk MAP products to provide additional information to communities regarding the impacts of SLR on future coastal flood risk. FEMA’s pilot study mapping products will be compared to the State of California SLR studies by other agencies that analyze future conditions coastal flooding scenarios.

FEMA Region IX engaged CCAMP stakeholders to help formulate the criteria for the SLR Pilot Study. Stakeholder collaboration will focus on the future conditions technical analysis, communication of results, and application of future SLR Studies on the West Coast. FEMA Headquarters is supporting the pilot study by leading a group of climate change, policy, and mapping experts that provide guidance to the study team. This “Peer Review Group” includes staff from the USACE, NOAA, United States Global Change Research Program, FEMA Regions IV, and IX and X, and others.
 
The pilot study will provide benefit-cost recommendations for conducting similar studies more broadly on the West Coast.  The pilot study will conclude with a presentation to the Peer Review and stakeholder groups during a coastal flood risk workshop planned for June 2014.  It is anticipated that city and county of San Francisco will use the SLR Risk MAP products to increase public awareness, encourage mitigation actions that reduce coastal flood risk, and/or adopt higher floodplain management standards for protecting lives and property along the open coast.

  • Local Coastal Programs Help Communities Rise to the Occasion with Successful Mitigation

    For decades, the Local Coastal Programs (LCPs) that govern land use along the California coastline were focused on conservation and recreation, but not mitigation. That’s changing thanks to a state grant program that has made millions of dollars available for local communities to update their LCPs, with priority given to those that address sea-level rise, increasing erosion, and other effects of climate change.

  • Analyzing and Mapping Wave Overtopping in FEMA Coastal Flood Studies

    Wave overtopping is a common coastal hazard and source of flooding along the Pacific coast. During severe coastal storms, high waves and wave runup can overtop coastal barriers including bluffs, dunes, seawalls, revetments, and beach berms. When this happens, the overtopping water floods the area immediately behind the barrier. In some cases, the overtopping water has enough energy and force to damage structures, including homes. Therefore, analysis of wave overtopping is typically an important part of a detailed coastal flood study. It is also useful for communities to understand the process of wave overtopping so they can identify where it is included on their coastal flood maps. Learn more about some of the physical aspects of wave overtopping, how it was analyzed and why it was mapped in the California Coastal Analysis and Mapping Project (CCAMP) Open Pacific Coast (OPC) Study in this article.
