Information Title Report from Public Works Committee dated June 21, 2016 1. Provide City Council Recommendation for Gibbon Street and 173rd Avenue Drainage Improvements Feasibility Report: Ratify the recommendation of the Public Works Committee to recommend that the City Council accept the feasibility report but deny approval of a drainage improvement project pending development of a cost effective, equitable funding program. 2. Review Updated Estimated Costs for Sunfish Lake Sedimentation Basin Improvements: No action taken; staff suggested discussing the item further while conducting research into what it would take to share costs. 3. Use of Excess Material for Dirt Road Improvements: Ratify the recommendation of the Public Works Committee to recommend that the City Council approve using the excess recycled asphalt material stored at the Public Works Campus to upgrade the road surface on Xenolith Street and 178th Lane in the Caroline Acres subdivision. Purpose/Background: The Public Works Committee held its regular meeting on June 21, 2016 and discussed the following cases: 1. Provide City Council Recommendation for Gibbon Street and 173rd Avenue Drainage Improvements Feasibility Report: City Engineer Westby reviewed the staff report and the Gibbon Street and 173rd Avenue drainage improvement project. He explained this plat is the Deerwood Plat, which is surrounded by wetlands/floodways. It was recorded in 1974. Several properties have experienced wet basements due to groundwater intrusion. Motion to ratify the recommendation of the Public Works Committee to recommend that the City Council accept the feasibility report but deny approval of a drainage improvement project pending development of a cost effective, equitable funding program. 2. Review Updated Estimated Costs for Sunfish Lake Sedimentation Basin Improvements: City Engineer Westby reviewed the staff report and request of the 14520 Sunfish Lake Drive NW property owner, Mr. Bergevin, that the City reconstruct specific stormwater treatment improvements impacting a portion of their back yard. The requested work includes constructing a settling basin at the end of the storm sewer outlet from Sunwood Drive where it intersects 145th Lane NW to reduce the frequency and volume of stormwater runoff running through the drainage swale along the rear of their lot. They are also requesting removal of existing cattails and other vegetation commonly found in wetlands from the swale and restoring the swale to a lawn condition. City Engineer Westby suggested discussing the item further while conducting research into what it would take to share costs. 3. Use of Excess Material for Dirt Road Improvements: Public Works Superintendent Riemer reviewed the staff report and requested direction on the use of excess pavement millings (combination of asphalt and Class V) for road surface improvements on Xenolith Street and 178th Lane. He said the only piece of equipment he would need to rent is one that compacts the gravel. Motion to ratify the recommendation of the Public Works Committee to recommend that the City Council approve using the excess recycled asphalt material stored at the Public Works Campus to upgrade the road surface on Xenolith Street and 178th Lane in the Caroline Acres subdivision. Action: Motion to ratify the recommendation of the Public Works Committee.
