FEMA Floodplain Maps
If you need contact information for flood plain managers other than Salt Lake County, please contact the Utah State Flood Plain Manager (801) 538-3332
Salt Lake County participates in FEMA's National Flood Insurance Program (NFIP). The program requires participating communities to enact ordinances that:
- protect the natural flood plain environment
- prevent damage to property or protect public safety.
FEMA maintains flood plain delineations on a set of maps called Flood Insurance Rate Maps (FIRM). Mortgage companies are required to determine if a property they are financing is located within a 100 year flood plain (any zone designation beginning with the letter A). If so the mortgage company can require the buyer to obtain flood insurance.
A buyer can complete an "Elevation Certificate" and submit it to FEMA for review and determination if they wish to challenge a Mortgage Company's determination. FEMA's website.
FEMA has released new Digital Flood Insurance Rate Maps (DFIRMs) effective September 21, 2001 and several revised maps effective May 15, 2002. These maps are available to view at our office. Anyone may purchase a Flood Insurance Rate Map from FEMA through the “Map Service Center”.
FEMA will release a complete set of revised DFIRM Maps Effective September 25, 2009. These maps include revisions to Big & Little Cottonwood Creek Flood Zones as well as new Detailed Flood Plain Information for the Big & Little Willow Creek Flood Zones.
Corrections to the Midas Creek Flood Zones have also been made and all maps have been updated to the NAD 1983 NAVD 1988 Datum (eliminating the need to calculate datum shifts).
Furthermore, FEMA's Elevation Certificate is being being replaced by the "MT-" series of forms. Please contact us at (385) 468-6600 for more information about using these new forms.
FEMA does not allow government entities to make determinations except as required for government business. Three items are needed to make a determination:
- Map Number
- Map Date
- Zone Designation
FEMA does not allow local governments to make insurance determinations. Please do not ask for a determination from Salt Lake County.
