Van Milligen, City Ma e FROM: Gus Psihoyos, City Engineer SUBJECT: US52 North Storm Sewer Improvement Project (CIP#7201810 & CIP#1001122) INTRODUCTION The enclosed resolutions authorize the public bidding procedure for the US52 North Storm Sewer Improvement Project. BACKGROUND In the fall of 1993, Flexsteel Industries, Dubuque County, and the City of Dubuque officially formed a partnership to address the inadequate drainage in the vicinity of Flexsteel. The City and County each committed to funding an equal third, up to $100,000, for the improvement project that was recommended by IIW Engineers. The project was completed in the winter of 1995 for $301,672.99. The project consisted of the construction of a levee, detention area, and pump station to handle stormwater from Olympic Heights, Highway US52, and Jackson Street. Figure 1 shows the components of the stormwater drainage plan established in 1995. In 1998, the City discovered that debris had filled the storm sewers that convey stormwater from Olympic Heights and US52 to the pump station. While storm sewers are typically designed to pass sediment that naturally passes through a watershed, the gradient, or slope, of the existing storm sewers and the high water table makes them susceptible to debris buildup. A Fiscal Year 1999 appropriation of $338,000 was established for drainage improvements. It was important to design a system not susceptible to the buildup of debris. The levee constructed in 1995 proved effective at preventing the flow of groundwater from north to south of the levee. As a result, it was possible to lower the water surface elevation south of the levee by reconfiguring the pump station. A lower water surface elevation would allow two things: storm sewers less susceptible to debris buildup and a detention basin with increased storage volume. Figure 1.

The drainage improvements in the vicinity of Flexsteel were split into three projects. The first project involved the excavation of the existing Flexsteel detention basin to increase the available storage volume. It was completed in the fall of 1999 for $32,760.26. The second project, completed in the spring of 2001 for $70,205.91, involved adding a second pump to the pump station with the capability of lowering the water surface elevation two feet below the level previously achieved level established in 1995. The last phase involves storm sewer reconstruction. In addition to the storm sewer improvements associated with the US52 North Storm Sewer Improvement Project, planned additional improvements involve adding ten additional catch basins to better drain US52. When complete, the current number of catch basins on US52 will be doubled. / ~e .~ The Iowa DOT has indicated that the second project could include substantial IDOT funding support. In addition, it can be done in conjunction with IDOT's resurfacing of US52 from W. 32"d Street to the NW Arterial. DISCUSSION The US52 North Storm Sewer Improvement Project consists of replacing a 24-inch diameter storm sewer with a 48-inch diameter storm sewer from the Flexsteel Pumping Station to US52. It will alleviate the ponding condition shown in Figure 3 below. With jurisdiction over US52, the IDOT also has an interest in adequate stormwater drainage of the highway. As a result, IDOT has indicated that the project is eligible for minor IDOT cost sharing. Poor stormwater drainage condition on US52 North.
