Floodplain Management

Chapter 40 of the Dallas County Code of Ordinance deals with Floodplain Management. Under Chapter 335 of the Iowa Code, Dallas County has the delegated power to enact regulations to secure safety from flood and to promote health and the general welfare. The Department of Planning and Development is responsible for enacting and enforcing these regulations in Dallas County’s unincorporated areas.

It is the purpose of this Ordinance to protect and preserve the rights, privileges, and property of Dallas County and its residents and to preserve and improve the peace, safety, health, welfare and comfort and convenience of it residents by minimizing flood losses through the following Floodplain Management provisions:

  1. Reserve sufficient flood plain area for the conveyance of flood flows so that flood heights and velocities will not be increased substantially.
  2. Restrict or prohibit uses which are dangerous to health, safety or property in times of flood or which cause excessive increases in flood heights or velocities.
  3. Require that uses vulnerable to floods, including public facilities which serve such uses, be protected against flood damage at the time of initial construction or substantial improvement.
  4. Protect individuals from buying lands which may not be suited for intended purposes because of flood hazard.
  5. Assure that eligibility is maintained for property owners in the community to purchase flood insurance through the National Flood Insurance Program.

The Department of Planning and Development has current FIRM (Flood Insurance Rate Map) Maps showing the most current flood hazard areas, floodways, and other flood areas affecting land within Dallas County.
