The "FP" Floodplain District encompasses the floodway and floodway fringes along the watercourse of the Meramec River and its tributary streams for which hydrographic study and calculation as determined by the U.S. Army Corps of Engineers (January, 1977) indicates a risk of life and property as a consequence of storm water run-off. The regulations of this district are supplemented and qualified by additional general regulations appearing elsewhere in this chapter.

In the floodway fringe of the "FP" Floodplain District, alternate zoning regulations shall apply under certain conditions as follows:
(a) 
Generally. For any lot or tract of land in the floodway fringe of the "FP" Floodplain District, an alternate district, which is designated on the zoning district maps and is the district designation following the letters "FP" on the maps, may be utilized if the particular property is placed in such condition, as required in this section, as to effectively, without increasing the flooding problems of other properties, remove the property from flooding, as determined by the U.S. Army Corps of Engineers study of January, 1977, as may be amended, and used as basic data for determining the extent of the Floodplain District. If the standards required by this section are satisfactorily met by the user of any lot or tract of land in the "FP" Floodplain District, such user may utilize the property for such uses and under such regulations as are contained in the district regulations of the district designated after the "FP" code designation as the alternate district for the particular property.
(b) 
Flood Protection Plan.
(1) 
In order to utilize the Alternate Floodplain District regulations, a property owner or user shall submit to the planning and zoning board a plan for adequate flood protection against the amount of water that would flow past the property in cubic feet per second, as determined by the above study used as basic data for determining the extent of the Floodplain Districts. Such plan must be approved by the Planning and Zoning Board before the alternate Floodplain District regulations may be utilized.
(2) 
The plan must include a report by a registered professional engineer of demonstrated competence in hydrology as to the adequacy of the proposed plan for flood protection relative to the elevation of the floodplain and the flow as determined in the aforementioned flood elevation study, the effect of the proposed improvement on the flood problems of other properties and such other hydrologic problems as may result from the improvements.
(3) 
The Planning and Zoning Board may require such additional data or engineering studies from the applicant as may be necessary to determine the adequacy of the proposed plan for flood protection.
(4) 
The approval of the Planning and Zoning Board of such plans for flood protection does not constitute a representation, guarantee or warranty of any kind by the City or by any officer or employee thereof as to the practicality or safety of any protective measure and shall create no liability upon or cause action against such public body, officers or employees for any damage that may result pursuant thereto.
(c) 
Non-conforming Buildings. Any non-conforming building in the "FP" Floodplain District, the use of which is a permitted use in the alternate district which applies to the particular location, may be rebuilt, extended or enlarged for a purpose permitted in the Section for removing the property from the danger of flooding as determined by the flood elevation study and as basic data for determining the extent of the Floodplain District; provided, that the building or structure complies with Chapter 10A. "Floodplain Management" of this Code.
