Purpose/Background: The Public Works Committee held it regular meeting on March 31, 2015 and discussed the following cases: 1. Consider Options for Addressing Stormwater Drainage Issues in Low Lying, Land Locked Areas: Civil Engineer II Linton reviewed the staff report and identified the 2014 areas of flooding concern. He identified the wetlands within the City, noting that approximately 20 to 25 percent of the City is wetland. He identified areas of flooding concern from previous years beginning in 1985 and moving forward to 2011 for comparison purposes. He explained the staff report focused on three primary areas of concern, and that the staff report lists these in order of priority based on magnitude and severity of property and structure impacts. The Gibbon Street area, rated the highest priority in the staff report, was discussed in detail first. Civil Engineer II Linton reviewed several potential routes of relief for this land -locked wetland, including relative elevation differences and any easements that existed along the routes. He discussed that ditch 66 was cleaned a few years prior and that weirs had been installed. He explained that vegetation management can occur within a wetland but the elevation cannot be changed. He noted that similar plans are available for discussion along the other two areas addressed within the case, but that residents from Gibbon Street are in attendance. No action taken. This item will be brought back on May 1th. 2. Consider the Surface Water Management Plan Update: Civil Engineer II Linton reviewed the staff report and briefly summarized the results of the pipe and pond summary. City Engineer Westby discussed any cost implications related to the updating of the Surface Water Management Plan. He stated there are no new mandates that will increase costs significantly, but incorporating the Atlas 14 stormwater data will have an impact on future costs as projects will be designed to a higher standard. Motion to ratify the recommendation of the Public Works Committee for City Council to approve the Surface Water Management Plan. 3. Consider Use of Sunwood Drive as Official Detour Route During Highway 10 and Armstrong Boulevard Interchange Construction: City Engineer Westby reviewed the staff report and stated that bids on the Armstrong Interchange project were opened and that construction will likely begin in early May and take one year to complete
