(A) Review criteria.
(1) No land shall be subdivided for building construction which is held unsuitable by the Planning Commission and Council for reason of flooding, inadequate drainage or inadequate water supply or sewage treatment facilities. All lots within the Floodplain District shall contain a building site at or above the regulatory flood protection elevation. All residential lots contiguous to a stream and served by municipal sewer shall contain at least 15,000 square feet and shall be at least 75 feet wide at the building line. All other residential lots served by municipal sewer shall contain 10,000 square feet and shall be at least 100 feet wide at the building line. All subdivisions shall have water and sewage disposal facilities that comply with the provisions of this subchapter and have road access no lower than two feet below the regulatory flood protection elevation. The following setbacks from the ordinary high water mark shall apply to all structures:
(a) Fifty feet for lots served by public sewer; and
(b) Seventy-five feet for lots not served by public sewer.
(2) For all subdivisions in the Floodplain District, the regulatory flood protection elevation, the required elevation of all access roads and required setbacks shall be clearly labeled on all required subdivision drawings and platting documents.
(B) Floodplain determination. When no detailed study has been performed, applicants shall provide the information required in § 153.084 of this chapter to determine the 100-year or regional flood elevation, and the regulatory flood protection elevation for the subdivision site.
(C) Removal of special flood hazard area designation. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100-year or regional flood elevation. FEMA’s requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested.
