Floodplain Management Program

Share | 

Floodplain Management Program

Washington County has a floodplain management program that was implemented following the publication of the first Flood Insurance Rate Maps for our County by the Federal Emergency Management Agency (FEMA) on May 1, 1978. The County’s floodplain management program is administered in accordance with the Floodplain Management Ordinance.

The County is responsible for managing development in the areas designated by FEMA as 100-year floodplains. FEMA has produced maps, called Flood Insurance Rate Maps (FIRMs), for Washington County that show the location of the 100-year floodplain. FEMA uses the term “Special Flood Hazard Area”, or “SFHA” as the area that is inundated by the 100-year flood. The 100-year floodplain is the area of land that has a 1% chance of being flooded in any given year.

By employing wise floodplain management through the implementation of our Floodplain Ordinance, Washington County strives to prevent loss of life and property; preserve the biological and environmental functions of our wetlands and waterways; and reduce the economic losses associated with flooding events.
