Sec.78-1120 Conditional Uses <br /> Any structure that is not elevated on fill or flood proofed in accordance with Section 78- <br /> 1119(a)—(b)and or any use of land that does not comply with the standards in Section 78- <br /> 1119(c) and(d)shall only be allowable as a conditional use. An application for a conditional use <br /> shall be subject to the standards and criteria and evaluation procedures specified in Sections 78- <br /> 1121 —78-1122 and 78-1135 of this Ordinance. <br /> Sec.78-1121 Standards for Flood Fringe Conditional Uses <br /> (1) Alternative elevation methods other than the use of fill may be utilized to elevate <br /> a structure's lowest floor above the regulatory flood protection elevation. These <br /> alternative methods may include the use of stilts,pilings,parallel walls,etc.,or <br /> above-grade,enclosed areas such as crawl spaces or tuck under garages. The <br /> base or floor of an enclosed area shall be considered above-grade and not a <br /> structure's basement or lowest floor if: 1)the enclosed area is above-grade on at <br /> least one side of the structure; 2)it is designed to internally flood and is <br /> constructed with flood resistant materials; and 3)it is used solely for parking of <br /> vehicles,building access or storage. The above-noted alternative elevation <br /> methods are subject to the following additional standards: <br /> a. Design and Certification-The structure's design and as-built condition <br /> must be certified by a registered professional engineer or architect as <br /> being in compliance with the general design standards of the State <br /> Building Code and, specifically,that all electrical,heating,ventilation, <br /> plumbing and air conditioning equipment and other service facilities <br /> must be at or above the regulatory flood protection elevation or be <br /> designed to prevent flood water from entering or accumulating within <br /> these components during times of flooding. <br /> b. Specific Standards for Above-grade, Enclosed Areas-Above-grade, <br /> fully enclosed areas such as crawl spaces or tuck under garages must be <br /> designed to internally flood and the design plans must stipulate: <br /> 1. A minimum area of openings in the walls where internal <br /> flooding is to be used as a flood proofing technique. There shall <br /> be a minimum of two openings on at least two sides of the <br /> structure and the bottom of all openings shall be no higher than <br /> one-foot above grade. The automatic openings shall have a <br /> minimum net area of not less than one square inch for every <br /> square foot subject to flooding unless a registered professional <br /> engineer or architect certifies that a smaller net area would <br /> suffice. The automatic openings may be equipped with screens, <br /> louvers,valves,or other coverings or devices provided that they <br /> permit the automatic entry and exit of flood waters without any <br /> form of human intervention; and <br /> 2. That the enclosed area will be designed of flood resistant <br /> materials in accordance with the FP-3 or FP-4 classifications in <br /> the State Building Code and shall be used solely for building <br /> access,parking of vehicles or storage. <br /> Page 11 of 24 <br />
