Flood Plain Development Permit


FEMA Flood Plain Management Regulations for construction or reconstruction in Flood Damaged Areas

Johnson County has adopted a Flood Plain Management Ordinance. As part of these provisions, a Flood Plain Development Permit must be obtained before development can occur in designated flood-prone areas. Contact the Johnson County Department of Planning and Zoning for information on the location of flood plains. Applications may be submitted to the Department of Planning and Zoning and must include the following information:

  • A legal description of the property.
  • Cost and market value estimates.
  • An indication of the use and occupancy for which the proposed work is intended.
  • Elevations of the 100-year flood level (established by a registered land surveyor, engineer, or architect), the lowest habitable floor of the building, and the "as built" habitable floor of the building once completed.

The application process for Flood Plain Development Permits may range from a few days to several weeks depending on individual circumstances.
