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 /> 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 /> 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 /> 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 /> 19 <br />
