A. Lands To Which This Chapter Applies: This chapter shall apply to all lands within the jurisdiction of the city shown on the official zoning map and the flood insurance rate map attached thereto as being located within the boundaries of the floodway, flood fringe, or general floodplain districts.
B. Establishment Of Official Zoning Map:
1. Adoption: The official zoning map together with all materials attached thereto is hereby adopted by reference and declared to be a part of this chapter. The attached material shall include the "Flood Insurance Study For Dakota County, Minnesota And Incorporated Areas", flood insurance rate map panels therein numbered 27037C0179E, 27037C0183E, 27037C0184E, 27037C0191E, 27037C0192E, 27037C0193E, 27037C0194E, 27037C0203E, 27037C0204E, 27037C0208E, 27037C0211E, 27037C0212E, 27037C0213E and 27037C0214E and the flood insurance rate map index (map numbers 27037CIND1A, 27037CIND3A and 27037CIND4A), all dated December 2, 2011, and prepared by the federal emergency management agency. The official zoning map shall be on file in the office of the city clerk and the zoning administrator.
C. Regulatory Flood Protection Elevation: The regulatory flood protection elevation shall be an elevation no lower than one foot (1') above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of floodway.
D. Regional Flood Elevation For Lakes: The regional flood elevation for lakes shall be as defined in the current "Flood Insurance Study For Dakota County, Minnesota And Incorporated Areas" or the Lakeville water resources management plan, as amended to reference the NAVD88 vertical datum, for those lakes for which no base flood elevation has been determined. These elevations are as follows:
Lake | Regional Flood Elevation
|
Lake | Regional Flood Elevation
|
Crystal Lake | 936.1 |
Goose Lake | 1,083.8 |
Kingsley Lake | 982.5 |
Lake Marion | 984.6 |
Lee Lake | 953.2 |
Orchard Lake | 978.5 |
Raven Lake | 1,100.2 |
E. Rules For Interpretation Of District Boundaries:
1. The boundaries of the floodplain overlay district shall be determined by scaling distances on the official zoning map.
2. Where interpretation is needed as to the exact location of the boundaries of the district as shown on the official zoning map, as for example, where there appears to be a conflict between a mapped boundary and actual field conditions, the city engineer shall make the necessary interpretation.
3. The decision of the city engineer will be based on elevations on the regional (100-year) flood profile, the ground elevations that existed on the site at the time the city adopted its initial floodplain ordinance or on the date of the first national flood insurance program map showing the area in the floodplain if earlier, and other available technical data.
4. The persons appealing the location of the district boundary shall be given a reasonable opportunity to present their case and to submit their own technical evidence if they so desire in accordance with chapter 7 of this title.
F. Annexation: The flood insurance rate map adopted by reference may include floodplain areas that lie outside the boundaries of the city as of December 2, 2011. If any of these floodplain land areas are annexed to the city after December 2, 2011, the newly annexed floodplain lands shall be subject to the provisions of this chapter immediately upon the date of annexation.
