(3) The plan may incorporate alternative procedures for removal of the material from the floodplain if <br /> adequate flood warning time exists. <br /> (f) Storage of materials and equipment below the regulatory flood protection elevation must comply with <br /> an approved emergency plan providing for removal of such materials within the time available after a <br /> flood warning. <br /> (g) Alternative elevation methods other than the use of fill may be utilized to elevate a structure's lowest <br /> floor above the regulatory flood protection elevation. The base or floor of an enclosed area shall be <br /> considered above-grade and not a structure's basement or lowest floor if: 1) the enclosed area is <br /> above-grade on at least one side of the structure; 2)it is designed to internally flood and is constructed <br /> with flood resistant materials;and 3)it is used solely for parking of vehicles, building access or storage. <br /> The above-noted alternative elevation methods are subject to the following additional standards: <br /> (1) Design and certification. The structure's design and as-built condition must be certified by a <br /> registered professional engineer as being in compliance with the general design standards of the <br /> state building code and, specifically, that all electrical, heating, ventilation, plumbing and air <br /> conditioning equipment and other service facilities must be at or above the regulatory flood <br /> protection elevation or be designed to prevent flood water from entering or accumulating within <br /> these components during times of flooding. <br /> (2) Specific standards for above-grade, enclosed areas. Above-grade, fully enclosed areas such as <br /> crawl spaces or tuck under garages must be designed to internally flood and the design plans <br /> must stipulate: <br /> a. The minimum area of openings in the walls where internal flooding is to be used as a <br /> floodproofing technique. There shall be a minimum of two openings on at least two sides of <br /> the structure and the bottom of all openings shall be no higher than one foot above grade. <br /> The automatic openings shall have a minimum net area of not less than one square inch for <br /> every square foot of enclosed area subject to flooding unless a registered professional <br /> engineer or architect certifies that a smaller net area would suffice. The automatic openings <br /> may be equipped with screens, louvers, valves, or other coverings or devices provided that <br /> they permit the automatic entry and exit of flood waters without any form of human <br /> intervention; and <br /> b. That the enclosed area will be designed of flood resistant materials in accordance with the <br /> FP3 or FP4 classifications in the state building code and shall be used solely for building <br /> access, parking of vehicles or storage. <br /> (Ord.
