1. What is a floodplain?

A floodplain is an area with water and ground surface elevations at or below the base flood or the 100-year frequency flood elevation.  Floodplains may also include detached special flood hazard areas, ponding areas, etc.  The floodplain is also known as the special flood hazard area (SFHA).

2. Can I develop on a floodplain?

Yes and No.  A person may not make any new constructions or improvements to land that is located in a designated regulatory floodway. However the person may construct and repair structures located in the flood fringe, if the proper permits have been issued by the Peoria County Planning and Zoning Department.

3. How do I know if my property is located in a floodplain?

Call the office to speak to a planner to determine if a property is located in a floodplain.  Please have a valid address or Parcel ID/Tax ID so that staff can find the correct property quickly and assist you.
