Mabusth Building & Zoning Administrator Cit> of Orono Box 66 Crystal Bay, Minnesota 55323 J Re: Orono Arena Sports Facility Sketch Plan Review #1738 Our File No. 139-1738 , jUN 11 1992 Dear Jeanne: We have reviewed the sketch plan and supporting documents submitted for the Orono Arena Sports Facility. Our brief overview of the facility was concentrated on the engineering issues related to sewer and water service, access roads, stormwater drainage and aesthetic issues due to the adjacent residential zoned property. The sanitary sewer can only be served by connecting to the existing sanitary sewer manhole and 8" VCP sewer, along the east side of Old Crystal Bay Road, approximately 800 feet south of the future School Drive. Due to the minimal elevation differential between the proposed site and the existing sanitary sewer, a grinder pump station will be required to service the sports facility. (The future school may be served by a gravity sewer). A forcemain would then be constructed from tl.e grinder pump station to the existing sanitary sewer manhole. The number of sewer units and the «ewci and water utility connection charges will need to be determined for both the sports facility and the future school. The sports facility site is 5.35 acres and the remaining school property is approximately 44 acres. The water service can be pi :vidf ’ by connecting to the existing* 8" CIP water main along the west side of Old Crystal Bay Road or to the recently con.stnicted 16" DIP water man near the City elevated water reservoir site. It should be noted that both connections will be required at some time to create a water main loop that will provide adequate fire protection flows/ceverage and a more reliabie system for the area. In the future, the City shoul.i extend the watei main to the east and north where a connection can be made to the City of Medina’s water syitem. This connection would be a tremendous improvement in the water systems of both cities. Wc would recommend that both the sanitary sewer forcemain and the water main be constructed to follow the proposed School Drive alignment. The forcemain and water main should then be extended north to the sports facility at right angles to this alignment. The Hennepin County Department of Public Works has required that only one street access be permitted onto County State Aid Highway (CSAH) 6. ITie street access would require the 2335 West Highway 36 • St. Paul, Minnesota 55113 • 612-636-4600 Kki&a .. V,.
