Proposed Map Revisions

The Flood Insurance Rate Map (FIRM) for a community depicts land which has been determined to be subject to a 1% (100-year) or greater annual chance of flooding in any given year.  The FIRM, which is published by the Federal Emergency Management Agency, is used to determine flood insurance rates and to help the community with floodplain management. New FIRM panels were published for the entire City on September 3, 2010. Digital copies of these FIRMs are available at this link DFIRM Page.

The City of Flagstaff is applying for Letters of Map Revision (LOMRs) from the Federal Emergency Management Agency (FEMA) in order to adjust the flood hazard boundaries shown on many of the new FIRM panels.  A map showing the areas of proposed LOMRs is shown below. Changes are proposed in these areas in order to more accurately show the floodplain and floodway limits. These changes are not the result of any new engineering studies or any actual or proposed physical changes to the watercourse. They are intended only to correct the new FIRM panels to more accurately show previously determined flood hazards.
