Assistant City Engineer Jankowski stated that MnIDOT provided the life cycle costs, explaining a bituminous street would need seal coating every seven years; therefore, depending on the street and traffic, concrete may be a better choice. Councilmember Dehen referred to a personal experience stating issues with concrete cracking and popping. He noted his concerns with concrete not being quality controlled. Public Works Director Olson agreed noting he had a similar experience in the mid- 1990s. At that time, clay in the rock would expand and pop out in the concrete and similar incidences can happen with asphalt as well. Councilmember McGlone stated some products fail and that the City could insure the work that the hired company is doing. He noted there are too many factors involved with concrete and he would like to see a comparison before a job is hired out as well as conditions that are included with a job. He added a better comparison over time would allow making a decision. Motion by Chairperson Elvig, seconded by Councilmember Dehen, to table considerations of concrete versus asphalt pavements and direct Staff to evaluate and present cost comparisons for future discussion. Motion carried. Voting Yes: Chairperson Elvig and Councilmembers Dehen and McGlone. Voting No: None. Case #6: Feasibility Study for Safety Improvements on Dysprosium / 143" Avenue / Argon Streets Assistant City Engineer Jankowski reviewed the staff report. Chairperson Elvig stated there is enough space to have sidewalks on both sides of the street, noting there is 80 feet of right -of -way. Councilmember Dehen stated if the sidewalk is built against the curb then there is no opportunity for trees to be planted. Assistant City Engineer Jankowski explained the location of the sidewalk would be on the west side of Dysprosium Street and would not lose any parking on the street. He stated the size would be a six -foot sidewalk and a seven -foot terrace. Public Works Director Olson stated the edge of the sidewalk that is close to the roadway would be on the curb line. The sidewalk would be built into the right -of -way toward the homes. Councilmember McGlone asked what criteria are being used to whether or not a sidewalk should be proposed. Councilmember McGlone also presented Pedestrian Safe Guidelines to Staff. Public Works Committee / August 19, 2009 Page 6 of 8
