      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

      • 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.
