9 <br /> <br />Rare, Unique or Significant Resources <br /> <br />Water willow (Decodon verticillatus), a MN DNR listed species of Special Concern, has been <br />identified on site per the wetland delineation report. It occurs on undisturbed lakeshores. <br />Conservation of this species depends on avoiding physical alterations of shoreline and <br />preserving native plant buffers. Minimal impacts to the resource along the lake shore are <br />allowed for a 20 ft wide access to the lake. <br /> <br />Wetland D is classified as a preserve due to high value amphibian habitat and vegetative <br />diversity. <br /> <br />These areas will be protected by a wetland buffer adjacent to the wetlands and shoreline. <br /> <br />Floodplain <br /> <br />The 2015 DFIRM indicates Zone AE floodplain along the lake. The FEMA base flood <br />elevation (BFE) is 910.2 EL. No floodplain impacts are proposed with this development. <br /> <br />Shoreland Management Overlay <br /> <br />The general purpose and intent of the Shoreland Management Overlay ordinance is to protect <br />public waters. Per the ordinance Policy statement, the uncontrolled use of shorelands of the <br />city affects the public health, safety and general welfare not only by contributing to pollution of <br />public waters, but also by impairing the local tax base. Therefore, it is in the best interests of <br />the public health, safety and welfare to provide for the wise subdivision, use and development <br />of shorelands of public waters. <br /> <br />As discussed, the site is located in a Shoreland Management Overlay district of Amelia Lake. <br />This lake is a classified as a Natural Environment Lake and has a 908.1 OHWL elevation. The <br />required OHWL setback is 150 ft for unsewered lots. The proposed houses and private septic <br />system setbacks are compliant. <br /> <br />Per City Code Section 1102.07(2)(a), structures and facilities must be located to meet all <br />setbacks. Stormwater facilities are not allowed within the 150 ft OHWL setback, 40 ft CSAH <br />54 setback or 10 ft side yard building setbacks. The plans shall be revised for Lot 1. <br /> <br />Except for allowed water-orientated accessory structures, accessory structures and facilities <br />shall meet the required principal structure setback and shall be centralized (City Code Section <br />1102.07(1)(c)6). <br /> <br />Per City Code Section 1102.87(1)(c)4 of the Shoreland Management Overlay ordinance, <br />impervious surface coverage on each lot must not exceed 30%. Per the Preliminary Plat, each <br />lot is under 5.9% impervious and meet the allowed impervious surface coverage requirements. <br /> <br />A native vegetated wetland buffer will be required as a stormwater management best <br />management practice (BMP) to minimize runoff pollutants from entering the lake. <br /> <br />Wetland/Shoreline Buffer Zone
