Plan (surface view) showing elevations or contours of the ground; pertinent structure, fill, or storage elevations; size, location, and spatial arrangement of all proposed and existing structures on the site, and location and elevations of streets. 3. Photographs showing existing land uses and vegetation upstream and downstream; and soil types; and 4. Profile showing the slope of the bottom of the channel or flow line of the stream for at least five hundred (500) feet in either direction from the proposed development. B. The applicant shall be responsible to submit one (1) copy of the above information to a designated engineer or other expert person or agency for technical assistance in determining whether the proposed use is in the Floodway or Flood Fringe District and to determine the Regulatory Flood Protection Elevation. Procedures consistent with Minnesota Regulations 1983, Parts 6120.5000-6120.6200 and 44 Code of Federal Regulations Part 65 shall be followed in this expert evaluation. The designated engineer or expert is strongly encouraged to discuss the proposed technical evaluation methodology with the respective Department of Natural Resources' Area Hydrologist prior to commencing the analyst. The designated engineer or expert shall: 1. Estimate the peak discharge of the regional flood. 2. Calculate the water surface profile of the regional flood based upon a hydraulic analysis of the stream channel and overbank areas. 3. Compute the floodway necessary to convey or store the regional flood without increasing flood stages more than 0.5 foot. A lesser stage increase than 0.5 foot shall be required if, as a result of the additional State increase, increased flood damages would result. An equal degree of encroachment on both sides of the stream within the reach shall be assumed in computing floodway boundaries. C. The City Administrator shall present the technical evaluation and findings of the designated engineer or expert to the City Council. The City Council shall formally accept the technical evaluation and the recommended Floodway and/or Flood Fringe District boundary or deny the permit application. The City Council, prior to official action, may submit the application and all supporting data and analyses to the Federal Emergency Management Agency, the Department of Natural Resources or the Planning Commission for review and comment. Once the Floodway and Flood Fringe Boundaries have been determined, the City Council shall refer the matter back to the City Administrator who shall process the permit application consistent with the applicable provisions of this Section. 1335.18 Zone A Lakes.
