PUBLIC WORKS PROJECTS <br /> <br />Department: Water <br /> <br /> <br />Item: Old Highway 8 NW Watermain Upgrades <br />County Road Watermain Upgrades <br /> <br />Year(s): 2031 – Highway 96 to Mounds View border <br />2032 – Phase 3 (from Rice Creek to Old Highway 8 at Mounds View border) <br />2053 - Longview to Rice Creek, just east of Poppyseed Drive <br /> <br />Cost: 2031 - $618,000 <br />2032 - $695,000 <br />2026-2041 $200,000 each year for County Road watermain starting in 2026 <br />2053 – $875,000 <br /> <br />Description: Starting in 2019 MnDOT will begin construction of MnPASS lanes from Roseville <br />to Lino Lakes. The City of New Brighton has an existing watermain that is located under 35W <br />that is undersized and beneath the existing bridge. MnDOT will include a utility betterment <br />project on behalf of New Brighton with their design-build contract. <br /> <br />As part of the Old Highway 8 Reconstruction project, a 12-inch watermain was constructed from <br />I-694 and extended past the Long Lake Regional Park entrance. In 2009, 2,800 linear feet of <br />watermain was directionally drilled along the west side of Old Highway 8 to south of Applewood <br />Point just north of Highway 96. The remainder of the loop will be coordinated with future phase <br />construction projects. Based on the fire flow analysis completed in 2016 it is not anticipated that <br />Phase 4 will be necessary. <br /> <br />Justification: The location of the existing watermain under 35W is nearly untraceable, and is <br />located under portions of the bridge abutments. The available fire flow for residents and <br />businesses in the SE portion of New Brighton would benefit from upsizing this section of main. <br /> <br />Currently, the only watermain servicing the entire NE portion of the City is an 8-inch cast iron <br />watermain installed in 1963. Some of the industrial businesses along the Old Highway 8 NW <br />corridor have experienced low flow alarms when the 8-inch is disrupted. Given our current <br />system demand from the industrial park located north of Highway 96, a new hotel at Highway 96 <br />which opened in 2009, and the future water demand of the Northwest Quadrant area, it is strongly <br />recommended the 8-inch pipe be upgraded to a 12-inch pipe. <br />21
