Y' )\ J- ■ Vi “ ■■.f t. • Re: Orono Arena Sports Facility Sketch Plan Review #1738 Our File Na 139-1738 JUM 11 •f Dear Jeanne: We have reviewed the sketch plan and supporting docments 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 proper^. The sanitary sewer can only be served by connecting to the existing sanitaiy 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 the grinder pump station to the existing sanitaiy sewer manhole. The nuinber of sewer and the sewer 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 approximate^' 44 acres. The water service can be provided by connecting to the existing 8" CIP water main along the west side of Old Crytial Bay Road or to the recently constructed 16** DIP water main 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/covera^ and a more reliable ^tem for the area. In the future, the City should extend the water main to the cast and north where a connection can be made to the City of Medma’s water system. This connection would be a tremendous improvement in the water systems of both citiesl We would recommend that both the sanitaiy 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 lo 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. The street access would require the / ■li y } 23ii VBkst Htelwwav • ft. Paul. MIrmesett §5113 • 6l3-636'4600
