(a) As a safety measure for the protection of the health and welfare of the people of the County, the Planning Board shall not approve any subdivision located in areas subject to flooding. If the subdivision is located in such area or an area having other physical impairment, the Board may approve the subdivision provided the developer or subdivider agrees to perform such improvements as will render the area substantially safe for residential, commercial or industrial uses. Prior to acting on a proposed subdivision located in a flood plain, the Board shall secure advice from the Miami Conservancy District.
(b) 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 runoff rates are increased.
(c) Approval shall not be given for streets within a subdivision which would be subject to 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.
