      The countywide Flood Insurance Rate Map (FIRM) for San Luis Obispo County and incorporated areas was finalized by Letters of Final Determination (LFD) issued by FEMA on May 16, 2012.  The LFD is a letter the Federal Emergency Management Agency (FEMA) sends to the Chief Executive Officer of a community stating that a new or updated FIRM will become effective in six months.  The updated FIRM panels will be effective on November 16, 2012.  The map panels and the DFIRM database are available for download here.

      Because FEMA is currently in the process of developing new procedures for evaluating and mapping flood risk behind non-accredited levees, panels with predicted flood risk from the non-accredited Santa Maria levee system were not included in this revision.  The U.S. Army Corps of Engineers is currently working toward rehabilitating and recertifying the levee.  The following FIRM panels will continue to remain in effect for floodplain management and flood insurance rating purposes: 06079C1619F, 06079C1638F, 06079C1639F, 06079C1880F, 06079C1885F, 06079C1902F, 06079C1905F, 06079C1906F, 06079C1910F, and 06079C1950F.  Once the U.S. Army Corps of Engineers, the City of Santa Maria, Santa Barbara County, and FEMA Region IX agree on the appropriate level of flood protection of the Santa Maria Levee, an evaluation methodology will be agreed upon and FEMA will complete the evaluation and develop 10 revised FIRM panels to replace them. 

      Whenever a FIRM change will incorporate new properties into a Special Flood Hazard Area, residents are encouraged to take advantage of the financial benefits offered by voluntarily purchasing low-cost Preferred Risk Policies (PRPs).  Additional information about PRPs can be found at  If you have insurance-related questions, please contact Edie Lohmann.  Edie can be reached by phone at 510-627-7235 or by email at

      • 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…)
