I, \ I. rnernorand urn . . TO: Terry Maurer I FROM: Tom Roushar~ I SUBJECT: Preliminary Plans Titled "Minnesota Army National Guard, Utility System Conversion, New Brighton, MN", Melchert/Block Associates, (MBA) December 1994 . DATE: January 3, 1995 . FILE: 520-053-11 This review of the preliminary plans is based on the assumption that the City of Arden Hills . will assume ownership of the sanitary and water facilities after they have been constructed. Review comments will be presented on a sheet-by-sheet basis followed by a general overview. .. SHEET NO.1 1. The note "Connect New 10" Watermain to Existing 6" Water Line" is in error. I 2. The 4" 0 forcemain and 10" 0 watermain are shown in a single 30" 0 casing. . Replacement of either of these lines in the future will be difficult. Separate casings or a larger single casing (assuming that the Minnesota Department of Health will approve) should be provided. . 3. The proposed alignment for the 30" 0 casing will have a major impact on the Hamline Avenue/Minnesota Trunk Highway 96 intersection during construction. Alternative . alignments to permit crossing of MTH 96 either east or west of the intersection should be evaluated. . 4. A 10" 0 watermain is proposed. I have serious reservations that a long 10" 0 dead- end can provide the required fire flow unless the National Guard buildings have fire . sprinkler systems. SHEET NO.2 . 1. The proposed lift station location is a poor location for Arden Hills to provide future .. maintenance. A better location would be in the Hamline Avenue right-of-way or just off the right-of-way. Under this scenario, a gravity line would be extended from the proposed lift station location out to Hamline Avenue. That portion of the gravity line off City right-of-way should remain the property of the National Guard and be treated . as a long sewer service. 520/0534.105 .jan
