FEMA Suspends Some Flood Map Reviews in Southern California

Release Date Release Number

OAKLAND, Calif. –The Federal Emergency Management Agency (FEMA) will suspend processing two types of flood map revision requests in six southern California counties starting August 14, 2020. This pause will affect only requests for Letters of Map Revision based on fill (LOMR-F) and Conditional Letters of Map Revision based on fill (CLOMR-F) in Los Angeles, Orange, San Diego, San Luis Obispo, Santa Barbara, and Ventura counties.

This suspension may last several years as FEMA assesses the potential effects of issuing LOMR-Fs and CLOMR-Fs on identified threatened and endangered species and their critical habitats. During this period, FEMA may also initiate a formal consultation with the U.S. Fish and Wildlife Service and the National Marine Fisheries Service. LOMR-Fs and CLOMR-Fs are revisions to Flood Insurance Rate Maps that show changes to the high-risk flood zones due to the placement of compacted fill.

FEMA will process applications for new LOMR-Fs or CLOMR-Fs received before August 14, 2020. Requests to reopen CLOMR-F and LOMR-Fs closed due to inactivity must also be received before August 14, 2020. New requests received after August 13, 2020 will not be processed until further notice.

Additional information is available by contacting the FEMA Map Information Exchange at 1-877-FEMA MAP (1-877-336-2627.)

Today’s announcement will not impact the sale of flood insurance.
