Update to Highlands at River Park By: Brian Olson, Principal City Engineer P.W. CASE # I Background: The propose of this case is to give you an update 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, we asked the Developer to send a notification (attached) 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. The Contractor may be present at the meeting to discuss this request. Action: Based upon discussion Reviewed by: Director of Public Works Finance Officer PW: 05/21/02
