   (b)   All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical, and water systems located and constructed to minimize flood damage.
   (c)   All subdivision proposals shall have adequate drainage provided to reduce exposure to flood damage.
   (d)   In all areas of special flood hazard where base flood elevation data are not available, the applicant shall provide a hydrologic and hydraulic engineering analysis that generates base flood elevations for all subdivision proposals and other proposed developments containing at least fifty lots or five acres, whichever is less.
   (e)   The applicant shall meet the requirement to submit technical data to FEMA in Section 1386.21(a)(1)D. when a hydrologic and hydraulic analysis is completed that generates base flood elevations as required by subsection (d) hereof.

   (g)   All final subdivision plats will provide the boundary of the special flood hazard area, the floodway boundary, and base flood elevations.
   (h)   In platted subdivisions, all proposed lots or parcels that will be future building sites shall have a minimum buildable area outside the natural (non-filled) one percent chance annual floodplain. The buildable area shall be large enough to accommodate any primary structure and associated structures such as sheds, barns, swimming pools, detached garages, on-site sewage disposal systems, and water supply wells, if applicable.
   (i)   Approval shall not be given for streets within a subdivision, which would be subject to flooding. All street surfaces must be located at or above the base flood elevation.
