5. The provisions of Section 10-05 0 (e) this Ordinance shall apply. c. Special Uses: Any structure that is not elevated on fill or flood-proofed in accordance with Section 1O-050(b)(1-2) or any use of land that does not comply with the standards in Section 1O-050(b)(3-4) shall only be allowable as a Special Use. An application for a Special Use shall be subject to the standards and criteria and evaluation procedures specified in Sections 1O-050(d)(e) and 1O-100(d). d. Standards for Flood Fringe Special Uses: 1. Alternative elevation methods other than the use of fill may be utilized to elevate a structure's lowest floor above the Regulatory Flood Protection Elevation. These alternative methods may include the use of stilts, pilings, parallel walls, etc., or above-grade, enclosed areas such as crawl spaces or tuck-under garages. The base or floor of an enclosed area shall be considered above-grade and not a structure's basement or lowest floor if: a) the enclosed area is above-grade on at least one side of the structure; b) it is designed to internally flood and is constructed with flood resistant materials; and c) it is used solely for parking of vehicles, building access or storage. The above-noted alternative elevation methods are subject to the following additional standards: (a) Design and Certification - The structure's design and as-built condition must be certified by a registered professional engineer or architect as being in compliance with the general design standards of the State Building Code and, specifically, that all electrical, heating, ventilation, plumbing and air conditioning equipment, and other service facilities must be at or above the Regulatory Flood Protection Elevation or be designed to prevent flood water from entering or accumulating within these components during times of flooding. (b) Specific Standards for Above-grade, Enclosed Areas - Above-grade, fully enclosed areas such as crawl spaces or tuck-under garages must be designed to internally flood and the design plans must stipulate: (1) The minimum area of openings in the walls where internal flooding is to be used as a flood-proofing technique. When openings are placed in a structure's walls to provide for entry of flood waters to equalize pressures, the bottom of all openings shall be no higher than one-foot above grade. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of flood waters. (2) That the enclosed area will be designed of flood resistant materials in accordance with the FP-3 or FP-4 classifications in the State Building Code and shall be used solely for building access, parking of vehicles or storage. 9
