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.

  • 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. For more information about what goes into a flood map, go to this infographic on FEMA’s website. (Read more…)
