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) is provided 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. No structures, not even water -orientated accessory structures, are allowed in the 75 ft wide wetland/shoreline buffer zone. Shore Impact Zone By definition, the shore impact zone is the land between the OHWL and a line parallel to it at a setback of 50% of the structure. Since the required structure setback is 150 ft, the shore impact zone is 75 ft from the OHWL. No structures, not even water -orientated accessory structures, are allowed in the 75 ft wide wetland/shoreline buffer zone. Comprehensive Plan The preliminary and final plat are consistent with the Comprehensive Plan is regards to resource management system, land use plan, housing plan, transportation plan and sanitary sewer and water supply plan. Environmental Board Comments The Environmental Board reviewed the proposed preliminary plat on August 25, 2021. Their recommendations are were noted in the October 1, 2021 memo from the Environmental Coordinator. These comments have been addressed. Additional comments from the June 21, 2022 Environmental Coordinator memo have also been addressed. One specific comment was to prohibit motorized boats on Amelia Lake. This requires adopting water surface restrictions with property owner input, a public hearing, City ordinance and MNDNR approval. At the September 8, 2021 Planning & Zoning Board meeting, the Board did not support regulating motorized boat activity on the lake without input from all the lake property owners. The Board suggested the property owners could pursue this avenue on their own if they desired. One resident, Steve Gallop-6102 Centerville Road, spoke in favor of the restriction. The City Council did not require any restrictions either. 10
