Case #4: Consider Storm Sewer Improvements at 168th and TH 47. Assistant Public Works Director Olson stated staff received'a cai1 from a resident after the recent heavy rains ream'ding the level of water in the adjacent pond. Staff visited the site and found that the water level in the pond was elevated. The site is north of 168th Avenue and west of TH 47. There is a drainage route out of the pond that includes the ditches along 168th Avenue, a culvert under TH 47 and ponds, swales and a pipe across the Rum River Hills Golf Course. The pipe under 168~' Avenue was not draining so the water was pumped over 16arb.Avenue. The System downstream across the golf course was flowing; however, it drained sloWl5;. The water flows into the Rum RAver on the east side of the golf course..The size of the pipe was checked after the iwater level was lowered. The pipe may be too small for the area draining to it. He advised, a drainage study should be performed to uerify the size of pipe required for this area. The analysis cm'~ be performed by staff. The pipe is on the golf course; however, water from the City storm sewer system passes through it so participation by the City is warranted, ff replacement of the pipe is justified it must be coordinated with the off-season of the golf course. The optimai time for replacement o f the pipe may be after the g'round freezes to prevent damage to the 'turf surface. Assistant Public Works Director Olson advised staff recommends performing the drainage study to analyze this area and provide a recommendation for irnprov/.ng the performance of the drainage system. Am a~eement would be drafted with the golf course to divide the costs of the improvements and provide access to the sire to perform the work. The project would be brought back to the City Council for authorization of the solicitation of bids and construction of the improvements. Motion by Mayor Oamec, seconded by Councihrlember Olson, to recommend that the City Council authorize He drainage study for the area around 165:~' Avenue and TH 47. Morion can'/ed.

Case #5: Project Closeout of TH 47 Improvement Project City Engineer Jankowski explained in May of 2000 construction was irdtiated on TH 47 between 142''d Avenue and Alpine Drive, which created a divided median with mm lanes and substantially widened the driving lanes. The City undertook the role of lead agency for this project as it was a high pr'iofity for the City. MnDOT assisted with this project by providing construction inspection and preparation of pay estimates for work performed by the contractor. He explained the project was opened to traffic in the fall of 2000, however, approximately. $500,000 of the total $4.9 m/Ilion project was incurred for work, which was performed over the succeeding construction year of 2001. The work done in 2001 included the installation of landscaping which the specifications stared must survive for two years before final payment can be processed. The last payment the City processed on this project was made in August of 2002. The prime contractor on this project, Richard I%nutson l. nc., has never requested any. additional payment, however, a landscaping subcontractor that provided trees for the project has requested -645- Public Works Committee / October 18, 2005 Page 5 of 8
