Principal City Engineer Olson stated that the purpose of the case was to update the Committee on the implementation of Highlands at River Park and give the people along Alpine Drive an opportunity to speak. Since the Highlands at River Park will affect Alpine Drive between Trunk Highway 47 and Roanoke Street NW, staff asked the Developer to send a notification to the residents along Alpine Drive to inform them of the reason for the disruption as well as give them an opportunity to speak about the project. The original plan to extend sewer and water to this subdivision indicated that the sanitary sewer was to be located 3 feet from the north curbline on Alpine Drive. In an effort to save as many trees and landscaping as possible we shifted the alignment of the sewer (which is 18 feet deep) 6 feet to the south. The Contractor has agreed to install trench boxes for the first 12 feet of depth to minimize the amount of disruption. One lane of traffic will be maintained throughout the process except while the crossings are made in the street at Barium Street NW, Zuni Street NW and Yakima Street NW. During the installation of these crossings, the road will need to be closed, for a period of a day per crossing. The Contractor has agreed to restrict his hours of operation during these crossings and all construction activity on Alpine Drive to 9:00 a.m. - 4:00 p.m. The Contractor has requested that construction activity be allowed before school ends. Staff feels that pedestrian safety is a must and has required that no construction activity occur until after schools lets out. Mayor Gamec inquired as to how long it would take to complete the work. Principal City Engineer Olson replied that they are estimating four to six weeks. Councilmember Zimmerman stated that 18 feet deep is very dangerous and would prefer that the road was shut down entirely to get the work done sooner. Principal City Engineer Olson replied that the contractor could complete the work in two weeks if the road was shut down. Councilmember Kurak inquired as to what the traffic count was during the peak hours. Principal City Engineer Olson replied that there are 1,200 vehicles on the road way during the day. Councilmember Kurak stated that she would agree with closing the road for two weeks. Mayor Gamec agreed as well. Motion by Councilmember Kurak, seconded by Councilmember Hendriksen, to recommend that the City Council authorize Alpine Drive to be closed between T.H.//47 and Roanoke Street for two weeks to allow the project to be done sooner. Further discussion: Principal City Engineer Olson noted that there will be some restoration issues, but the contractor has assured staff that they would be completely done with curb and gutter and new bituminous within four weeks. Councilmember Zimmerman requested that staff send out notices that there will be construction in the area. Principal City Engineer Olson noted Public Works Committee/May 21, 2002 Page 9 of 12
