The City of Arlington submitted the Fish Creek and Cottonwood Creek watershed study to FEMA in 2014 in order to incorporate the new technical data into the Flood Insurance Rate Map (FIRM) and the Flood Insurance Study (FIS) data. FEMA has developed preliminary FIRM and FIS data for the Fish Creek and Cottonwood Creek watersheds using the information developed in the City's study of those creeks.

Changes to the floodplain maps will include:

  • Addition or modification of Base Flood Elevations
  • Special Flood Hazard Area boundary changes
  • Changes to flood zone designations
  • Revisions to the floodway boundaries

Once the FIRM map panels become effective, buildings that are newly mapped into the Special Flood Hazard Area or High-Risk Area, will have 12 months from the effective date to still receive the Preferred Risk Policy premium rates. After the first year, rates will then increase up to 18 percent a year.

As part of the map revision process you may appeal the preliminary FIRM and FIS data with any technical engineering data that may represent the area better. The appeals period begins around June 25, 2017. There is a 90 - day period in which you can appeal the map revisions. For more information please visit or call FEMA Map Information at 1-877-336-2627.

Don't wait to purchase flood insurance!  There is a 30-day waiting period for flood policies to take effect. Contact your local insurance agent for more information on rates and policies.
