MINUTES OF THE REGULAR ORONO CITY COUNCIL. MEETING HELD ON OCTOBER 10, 1994 (#9 - Item #1962 - Dayton/Prairie Restorations - Continued) Galfron said this request is for a conditional use permit to excavate a pond in an existing type 7 wetland and disposal of the soil materials on the site. This pond is located southeast of Long Lake and north of Old Long Lake Road. One proposed disposal site is on the west side of the north lot on what had been a horse riding arena. The second disposal site is south of Old Long Lake Road and has been revised to not encroach on a wetland identified in the National Wetland Inventory. The pond plan has been revised to involve only 41,000 cubic yards of excavation, leaving islands within the pond. A berm will be built to help contain the spoils during the process. This proposal has been sent to the Watershed District, who will discuss it at their November meeting. The City Engineer has requested additional information on the outlet, and Staff has requested documentation be provided from the Corps of Engineers. Callahan noted that this item was moved up to the City Council before all permits had been received and issues resolved due to the number of permits needed and the magnitude of the project. He noted the Planning Commission generally favored the project. r� Hurr asked confirmation that no permit was needed from the DNR. Gaffron indicated this is correct and since no filling or draining would occurr, the Wetland Conservation Act does not apply. This land is located in the National Wetland Inventory but not on either the City's or the DNR's lists of protected wetlands. This narrows down the • approval needed to be from the City Council, the Watershed, and perhaps, the Corps of Engineers. Goetten noted the size of the pond was decreased to 6.9 acres. Bowen noted that the boundaries have shrunk and volume to be excavated is down by 20 %. Goetten asked how the applicant proposes to clean up the area, make road repairs where needed, and maintain the road. Bowen said this is unresolved and has yet to be worked out with the Staff. He is amenable to posting a bond or making it part of the specifications. Bowen noted the work would be done in the winter. Jabbour voiced concern with the wetness of the spoils causing possible flooding in the spring. Bowen said they are unable to pile the material adjacent to the excavation because that area is wetland, and it would be constituting filling of wetland. It is planned to allow time for the material to dry out, possibly taking two to three years, with temporary seeding and later final seeding. The material is mainly peat and organic in nature and will eventually dry out. It was noted that the west disposal site will not end up any higher than the current high ground now. Callahan did comment that this would destroy buildable land as septic systems cannot be placed on filled areas. A silt fence will be dug into the ground at the spoil site perimeter, and Cook said the berm will be dug down to stop the spoils from running off. No action was required. 4 •
