Duchesne County Approves “100-year” Flood Maps

On 10/16/23, The Duchesne County Commission approved base-level engineering (BLE) floodplain maps of Duchesne County as part of a larger project produced by the Utah Division of Emergency Management and the Federal Emergency Management Administration. These maps, sometimes known as "100-year," or 0.1 % flood maps, can now serve as the data required to administer the County's Flood Damage Protection ordinance. The language in the current ordinance relies on the best available data. Before these BLE  floodplain maps, no floodplain mapping was available to reference since there has been no flood mapping in Duchesne County outside of Duchesne City and Myton City.
