(d) The placement of more than 1,000 cubic yards of fill or other similar material on <br />a parcel (other than for the purpose of elevating a structure to the regulatory flood <br />protection elevation) must comply with an approved erosion/sedimentation control plan. <br />1. The plan must clearly specify methods to be used to stabilize the fill on site for <br />a flood event at a minimum of the regional (1% chance) flood event. <br />2. The plan must be prepared and certified by a registered professional engineer or <br />other qualified individual acceptable to the City Council. <br />3. The plan may incorporate alternative procedures for removal of the material <br />from the floodplain if adequate flood warning time exists. <br />(e) Storage of materials and equipment below the regulatory flood protection <br />elevation must comply with an approved emergency plan providing for removal of such <br />materials within the time available after a flood warning. <br />(f) 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 above - <br />grade, enclosed areas such as crawl spaces or tuck under garages. The base or floor of an <br />enclosed area shall be considered above -grade and not a structure's basement or lowest <br />floor if: 1) the enclosed area is above -grade on at least one side of the structure; 2) it is <br />designed to internally flood and is constructed with flood resistant materials; and 3) it is <br />used solely for parking of vehicles, building access or storage. The above -noted <br />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 <br />certified by a registered professional engineer or architect as being in compliance with <br />the general design standards of the State Building Code and, specifically, that all <br />electrical, heating, ventilation, plumbing and air conditioning equipment and other <br />service facilities must be at or above the regulatory flood protection elevation or be <br />designed to prevent flood water from entering or accumulating within these components <br />during times of flooding. <br />2. Specific Standards for Above -grade, Enclosed Areas - Above -grade, fully <br />enclosed areas such as crawl spaces or tuck under garages must be designed to internally <br />flood and the design plans must stipulate: <br />a. The minimum area of openings in the walls where internal flooding is to be <br />used as a floodproofing technique. There shall be a minimum of two openings on at least <br />two sides of the structure and the bottom of all openings shall be no higher than one foot <br />above grade. The automatic openings shall have a minimum net area of not less than one <br />square inch for every square foot of enclosed area subject to flooding unless a registered <br />professional engineer or architect certifies that a smaller net area would suffice. The <br />automatic openings may be equipped with screens, louvers, valves, or other coverings or <br />devices provided that they permit the automatic entry and exit of flood waters without <br />any form of human intervention; and <br />b. That the enclosed area will be designed of flood resistant materials in <br />13 of 25 <br />
