Floodplain The 2015 DFIRM indicates Zone AE floodplain along the lake. The FEMA base flood elevation(BFE) is 910.2 EL. No floodplain impacts are proposed with this development. Shoreland Management Overlay The general purpose and intent of the Shoreland Management Overlay ordinance is to protect public waters. Per the ordinance Policy statement, the uncontrolled use of shorelands of the city affects the public health, safety and general welfare not only by contributing to pollution of public waters, but also by impairing the local tax base. Therefore, it is in the best interests of the public health, safety and welfare to provide for the wise subdivision, use and development of shorelands of public waters. As discussed, the site is located in a Shoreland Management Overlay district of Amelia Lake. This lake is a classified as a Natural Environment Lake and has a 908.1 OHWL elevation. The required OHWL setback is 150 ft for unsewered lots. The proposed houses and private septic system setbacks are compliant. Per City Code Section I IO2.07(2)(a), structures and facilities must be located to meet all setbacks. Stormwater facilities are not allowed within the 150 ft OHWL setback, 40 ft CSAH 54 setback or 10 ft side yard building setbacks. The plans shall be revised. Except for allowed water-orientated accessory structures, accessory structures and facilities shall meet the required principal structure setback and shall be centralized(City Code Section 1102.07(1)(c)6). Per City Code Section I IO2.87(1)(c)4 of the Shoreland Management Overlay ordinance, impervious surface coverage on each lot must not exceed 30%. Per the Preliminary Plat, each lot is under 5.9% impervious and meet the allowed impervious surface coverage requirements. A native vegetated wetland buffer will be required as a stormwater management best management practice (BMP) to minimize runoff pollutants from entering the lake. Wetland/Shoreline Buffer Zone Amelia Lake is one of the few unimpaired lakes in the city and efforts to protect and improve the natural resource should be implemented with any development. A 75 ft wide vegetated wetland/shoreline buffer along Wetland A (lake)will be required as a stormwater management best management practice (BMP) to minimize runoff pollutants from entering the lake. The buffer will also help stabilize the shoreline, reduce erosion and support aquatic plants and wildlife. One (1) access opening through the wetland buffer to the lake no greater than twenty(20) ft wide is allowed per lot. 10
