ENVIRONMENTAL BOARD MEETING OCTOBER 30, 2002 reviewal period. She had pictures of the island with the rookery and a drawing of the area with the ponding. She redefined the church as a mega church due to its size, potential number of members, and the size of the purchased site of about 92 acres. She expressed concern that Art Hawkins had not ever been approached concerning the impact the development would have on the herons. Wayne LeBlanc of 1677 Peltier Drive, Centerville, MN, President of the Peltier Lake Association indicated that Peltier Lake was very sensitive. He stated everything should be done to improve the water quality. At present, there was no impervious, but it would become 16 acres of impervious with the new development. He was concerned over the potential salt and oil runoff, because the surface water went into Peltier Lake. Another issue was there was no municipal sewer service for 4 -6,000 people in church per week. He expressed concern that the land was so low that it would require imported soils that might fmd their way to the lake. The Northern part of Peltier Lake would go into the aquifer. The noise, traffic, and lights would impact the wildlife. Typically a church spire was illumined facing upward. Nesting materials were probably obtained from the site. He believed that a full Environmental Impact Survey was needed to address these issues. 5. ACTION ITEMS A. Car Wash, Ray Benkler, Lake Drive, CUP and Site Plan Review Asleson reviewed for the Board the background highlighting the recommendations put forth from the Board in August. He stated that unique things had been done in the site design with infiltration. On a commercial site, if the groundwater could potentially become polluted, the development should not use infiltration practices. He introduced William McCully, engineer for Rehbein. Mr. McCully stated that the site was 1.5 acres with runoff in all directions, and they had attempted to implement new technologies. The Board had approved grass parking. He introduced Netlawn and Netlawn grass, and rainwater gardens for the front, which could grow into swales for infiltration. Mr. McCully discussed the three -foot separation for septic systems as defined by the MPCA. The groundwater elevation of was 897 feet. He stated that there would be a three - foot separation between the seasonally high water table and the bottom of the pond. He did not believe that groundwater pollution was a concern, because Netlawn would be used and then sand beneath it. The sand to be used was the dredged sand from the Mississippi River, which would be located below the organic layer. The water would flow into the ponds when the system had become supersaturated. The front of the building, the islands were depressed instead of raised. In another site, the system had been implemented for two months, and no water had left the site. The car wash site, oil eating microbes would be in the organic layer. Flexpave 50 is engineered to flex so it can expand and contract. DRAFT MINUTES
