A. Permitted Uses:
1. The uses listed as permitted uses in section 11-101-11 of this chapter are permitted uses in the general floodplain district.
2. All other uses shall be subject to the floodway/flood fringe evaluation criteria pursuant to subsection B of this section. Section 11-101-11 of this chapter shall apply if the proposed use is in the floodway district and section 11-101-13 of this chapter shall apply if the proposed use is in the flood fringe district.
B. Procedures For Floodway And Flood Fringe Determinations Within The General Floodplain District: Upon receipt of an application for a permit or other approval within the GFD district:
1. The applicant shall be required to furnish such of the following information as is deemed necessary for the determination of the regulatory flood protection elevation and whether the proposed use is in the FW, floodway or the FF, flood fringe district:
a. Typical valley cross section(s) showing the channel of the stream, elevation of land areas adjoining each side of the channel, cross sectional areas to be occupied by the proposed development, high water information and peak discharge of the regional flood as identified in the Lakeville water resources management plan.
b. Plan (surface view) showing the nature, locations, dimensions, and elevation of the lot, contours of the ground, fill; storage of materials; floodproofing measures; the arrangement of all proposed and existing structures on the site; locations and elevations of streets; existing and proposed utilities, septic tanks or water wells; existing land uses and vegetation upstream and downstream; soil type, and the relationship of the above to the location of the channel.
c. Photographs showing existing land uses, vegetation upstream and downstream, and soil types.
d. Profile showing the slope of the bottom of the channel or flow line of the stream for at least five hundred feet (500') in either direction from the proposed development.
2. The city engineer shall determine whether the proposed use is located within a floodway or flood fringe area by computing the floodway necessary to convey or store the regional flood without increasing flood stages more than 0.5 feet. A lesser stage increase than 0.5 feet shall be required if, as a result of the additional stage 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. Upon such determination, the applicable conditions, provisions and restrictions shall be imposed.
3. Procedures consistent with Minnesota regulations 1983, parts 6120.5000 - 6120.6200 and 44 code of federal regulations part 65 shall be followed by the city engineer in this evaluation. (Ord. 883, 9-19-2011)
