CABARRUS COUNTY ZONING ORDINANCE CHAPTER 16 -FLOOD DAMAGE PREVENTION (4) Elevated Buildings Fully enclosed area, of new construction and substantially improved structures, which is below the lowest floor: (a) Shall not be designed or used for human habitation, but shall only be used for parking of vehicles, building access, or limited storage of maintenance equipment used in connection with the premises. Access to the enclosed area shall be the minimum necessary to allow for parking of vehicles (garage door) or limited storage of maintenance equipment (standard exterior door), or entry to the living area (stairway or elevator). The interior portion of such enclosed area shall not be finished or partitioned into separate rooms, except to enclose storage areas; (b) Shall be constructed entirely of flood resistant material �t least to the Regulatory Flood Protection Elevation; (c) Shall include, in Zone AE, flood openings to automatically equalize hydrostatic flood forces on walls by allowing for the entry and exit of floodwaters. To meet this requirement, the openings must either be certified by a professional engineer or architect or meet or exceed the following minimum design criteria: (i) a minimum of two flood openings on different sides of each enclosed area subject to flooding; (ii) the total net area of all flood openings must be at least one (1) square inch for each square foot of enclosed area subject to flooding; (iii) if a building has more than one enclosed area, each enclosed area must have flood openings to allow floodwaters to automatically enter and exit; (iv) the bottom of all required flood openings shall be no higher than one (1) foot above the adjacent grade; A (v) % flood openings may be equipped with screens, louvers, or other coverings or devices, *provided they permit the automatic flow of floodwaters in both directions; and (vi) enclosures made of flexible skirting are not considered enclosures for regulatory purposes, and, therefore, do not require flood openings.
