Zoning File #2103 Januarj' 11, 1996 Page 3 finished grade, refer to Exhibit G. Applicant also notes the need for major soil correction when you move eastward. There are additional site constraints, i.e. retention ponds, parking. etc. Wetlands Review Exhibit I, specifically the last page of the design packet that locates the two wetland basins on the property. Note there are no Orono designated wetlands on this property. Applicant proposes the placing of a parking lot within basin 2 along the south lot line. As applicant's addendum information notes basin 2 is not a long-term wetland but umntentional. Earlier grading changes forced drainage to collect in the area. The two wetlands will be regulated by the Minnehaha Creek Watershed District and Corps of Engineers. All permit applications with both agencies should be filed prior to the filing of the formal application with the City. Applicant may be able to obtain a certificate of exemption from the Watershed District for the parking improvement. Sewer and Water Review Exhibit J, Gustafson ’s report and copy of as-builts, municipal water is 400’ to the south and sewer 1,100’. His report asks that the water main be extended to the northwest comer of Old Crystal Bay Road and County Road 6 for future connection to the City of Medina. Staff would not recommend passing this cost on to Hockey Association and would delay further extension for a request from the City of Medina. The engineer notes that because of the lower elevations of this site, it will be necessary to pump waste water from a grinder pumping station through a force main to the existing gravity sewer. Upon formal application, the ^plicmt will be expected to provide plans and specs for the sanitary sewer and water main extensions in addition to as-built drawings being provided to the City upon completion of the project. The property is not located within the Metropolitan Urban Sewer Area. The 4.4 acre parcel has been included in the current Comp Plan Amendment to be filed with the Met Council January 1996. Drainage/Stormwater Review Exhibit E, all drainage is directed to northeast into a proposed stormwater retention pond that would eventually drain to basin 1 wetland and eventually to the existing culvert at Old Crystal Bay Road. The engineer recommends that a skimmer structure be included at the pond outlet before entering basin 1 wetland. Drainage and ponding calculation shall be provided with formal application along with the detail of the outlet structure and pond elevations should be shown on the final grading plan. Engineer is also asking that the parking lot and entrance have storm sewer for proper drainage. , ■ < «1 ■■ t V 11 ■
