(A) Review criteria. No person or owner shall subdivide land that the city decides is unsuitable for building or is unsuitable for new construction because of flooding, inadequate drainage, water supply or sewage treatment facilities. The city shall approve all subdivision requests (subject to the requirements in Ch. 158 and Ch. 160 of this code of ordinances to ensure that all lots within the floodplain districts would have a building site outside of the Floodway District at or above the regulatory flood protection elevation. All subdivisions shall have access to public water and to the city sanitary sewer system and facilities that meet the provisions of this chapter. All subdivisions shall have road access both to the subdivision and to the individual building sites no lower than two feet below the regulatory flood protection elevation. For all subdivisions in the Floodway or Flood Fringe District boundaries, the applicant, owner or project engineer shall clearly label the regulatory flood protection elevation and the required elevation of all access roads on all subdivision drawings and platting documents.
(B) Procedures for determining 1% annual chance flood elevation (100-year flood elevation) in Zone A. In a designated Zone A area, applicants shall provide the information required in § 154.040(B) of this chapter to determine the 100-year 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 1% annual chance flood elevation (100-year flood elevation). FEMA’s requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. The applicant, owner or contractor should investigate these standards before starting site preparation if requesting a change of special flood hazard area designation.
