(A) Prohibition of development in areas susceptible to flooding. Land subject to flooding or otherwise uninhabitable shall not be platted for residential, commercial, or industrial uses or for any other use which may increase the danger of health, life, property, or aggravate erosion or flood hazards. Such land within the subdivision shall be set aside on the plat for such uses as will not be endangered by periodic or occasional inundation or will not result in conditions contrary to the public welfare (e.g., use as open space, extensive recreation use, conservation purposes). To insure that lots will be located on land where they will provide flood-free sites, the Planning Commission, or its duly authorized representative, may require the subdivider to provide elevation and flood profiles sufficient to demonstrate the sites will be free from the danger of flooding. Fill may be used in flood danger areas to render lots habitable if such fill does not inhibit the flow of the waters and thereby unduly increase flood heights in other areas and meets with the approval of the Planning Commission, or its duly authorized representative. Such information shall be prepared by a registered civil engineer.
(B) Stream easement. If a stream flows through, or adjacent to, the proposed subdivision, the plat shall provide for a storm water easement or drainage right-of-way along the stream for a floodway of at least ten feet. For the smaller streams, the plat shall provide for channel improvement to enable them to carry all reasonable floods within banks. The floodway easement shall be wide enough to provide for future enlargement of the stream channels as adjacent areas become more highly developed and run-off rates are increased.
(C) Streets. Approval shall not be given for streets within a subdivision which would be subject to inundation or flooding. All streets must be located at elevations which will make them flood-free in order that no portion of the subdivision would become isolated by floods.
