   1.   Applications and supporting documents for development in flood hazard areas;

   2.   Permits issued in flood hazard areas;

G104.2.1 Flood zone compliance plans.

The permit application shall include flood zone compliance plans. Such plans shall include plans and drawings, shall be sealed by a registered design professional and shall include a site plan and the following information and any other data as may be required by the department:

   1.   Flood design class assigned according to ASCE 24;

   2.   A delineation of the flood hazard areas, including identification of the base flood elevation(s), design flood elevations and stillwater flood depth;

   3.   If applicable, the location of the regulatory floodway;

   4.   For all proposed structures, spot ground elevations at building corners and in 20-foot (6096 mm) or smaller intervals along the foundation footprint, or 1-foot (305 mm) contour elevations throughout the building site;

   5.   Proposed locations of water supply, sanitary sewer, and utilities;

   6.   Drainage patterns and facilities;

   7.   Foundation design details, including but not limited to:

      7.1.   Proposed elevation of the lowest floor including basement (for flood zone purposes) of all structures;

      7.2.   For crawl spaces and enclosed parking, storage and building access that are wet floodproofed below the design flood elevation, location and total net area of foundation openings in accordance with ASCE 24;

      7.3.   For dry floodproofed spaces in buildings or structures that are nonresidential (for flood zone purposes), the proposed elevation to which the enclosure will be dry floodproofed in accordance with ASCE 24;

      7.4.   Any proposed fill and excavation details ; and

      7.5.   In coastal high-hazard areas and coastal A-zones, the proposed elevation of the bottom of the lowest horizontal structural member of the lowest floor; and

   8.   For structures in coastal high-hazard areas or coastal A-zones, and for dry-floodproofed structures: flood loading and parameters including average velocity of water (V), debris impact load (F i ), scour depths, and wave loads (F t or F D ).

   Exception: Applications for subdivisions shall comply with Section G302.
