The FP prefix designation constitutes a zoning overlay district, and the addition or removal of the FP prefix constitutes zoning action requiring due process provided under state law. Further public notice to all downstream property owners within the City with like FP zoning is required prior to any such zoning action.

To provide for the appropriate use of land which has a history of inundation or is determined to be subject to flood hazard and to promote the health, safety and general welfare of the community, portions of certain districts are designated with a floodplain prefix FP and shall be subject to the following provisions.

In this district no land shall be used except for one or more of the following permitted uses to the extent that they are not prohibited by other regulations or ordinances and provided that such uses do not require above-ground structures, filling or storage of material or equipment except as herein specifically authorized.

The City Council may, after public hearing, amend the zoning classification of any property by adding the floodplain FP prefix designation based on hydraulic engineering studies indicating new boundaries of the area that is subject to inundation by floodwaters. The City Council shall provide for the addition of such floodplain FP prefix designation to the zoning district maps.

The City Council, in considering and determining its decision relative to any application for the removal of the floodplain FP prefix designation, shall require the applicant to furnish to the administrator fill and development plans (hydraulic calculations concerning maximum high water and flow rates and their effect on abutting, lateral, and downstream properties) and data concerning the operation, location, function and characteristics of any use of land or building proposed. The application will not be scheduled for public hearing until the city engineer certified information furnished is adequate for review and comment as required in this section.
