ARTICLE VIII. FLOODPLAIN MANAGEMENT* Page 4 of 5 ' <br /> Sec. 78-1123. Permitted uses. <br /> (a) The uses listed in section 78-1114 of this article shall be permitted uses. <br /> (b) All other uses shall be subject to the floodway/flood fringe evaluation criteria pursuant to <br /> section 78-1124 below. Division 4 shall apply if the proposed use is in the floodway district and <br /> division 5 shall apply if the proposed use is in the flood fringe district. <br /> Sec. 78-1124. Procedures for floodway and flood fringe determinations within the <br /> general flood plain district. <br /> (a) Upon receipt of an application for a permit or other approval within the general flood plain <br /> district, the applicant shall be required to furnish such of the following information as is deemed <br /> necessary by the planning director for the determination of the regulatory flood protection <br /> elevation and whether the proposed use is within the floodway or flood fringe district. <br /> 1. A typical valley cross-section(s) showing the channel of the stream, elevation of land <br /> areas adjoining each side of the channel, cross-sectional areas to be occupied by the <br /> proposed development, and high water information. <br /> 2. Plan (surface view) showing elevations or contours of the ground, pertinent structure, <br /> fill, or storage elevations, the size, location, and spatial arrangement of all proposed and <br /> existing structures on the site, and the location and elevations of streets. <br /> 3. Photographs showing existing land uses, vegetation upstream and downstream, and <br /> soil types. <br /> 4. Profile showing the slope of the bottom of the channel or flow line of the stream for at <br /> least 500 feet in either direction from the proposed development. <br /> (b) The applicant shall be responsible to submit one copy of the above information to a <br /> designated engineer or other expert person or agency for technical assistance in determining <br /> whether the proposed use is in the floodway or flood fringe district and to determine the <br /> regulatory flood protection elevation. Procedures consistent with Minnesota Regulations 1983, <br /> Parts 6120.5000--6120.6200 and 44 Code of Federal Regulations Part 65 shall be followed in <br /> this expert evaluation. The designated engineer or expert isstrongly encouraged to discuss the <br /> proposed technical evaluation methodology with the respective department of natural resources' <br /> area hydrologist prior to commencing the analysis. The designated engineer or expert shall: <br /> 1. Estimate the peak discharge of the regional flood. <br /> 2. Calculate the water surface profile of the regional flood based upon a hydraulic <br /> analysis of the stream channel and overbank areas. <br /> 3. Compute the floodway necessary to convey or store the regional flood without <br /> increasing flood stages more than 0.5 foot. A lesser stage increase than 0.5 shall be <br /> required if, as a result of the additional stage increase, increased flood damages would <br /> result. An equal degree of encroachment on both sides of the stream within the reach <br /> shall be assumed in computing floodway boundaries. <br /> (c) The planning director shall present the technical evaluation and findings of the designated <br /> engineer or expert to the governing body. The governing body must formally accept the <br /> technical evaluation and the recommended floodway and/or flood fringe district boundary or <br /> deny the permit application. The governing body, prior to official action, may submit the <br /> application and all supporting data and analyses to the Federal Emergency Management <br /> Agency, the department of natural resources or the city council forreview and comment.
