Public Works Committee 5. 3. Meeting Date: 07/17/2012 Submitted For: Grant Riemer By: Grant Riemer, Engineering/Public Works Title: Review Overlay Project 11-05 (157th Ln east of Ramsey Blvd) Background: In April of 2011 an overlay project was approved for 157th Ln east of Ramsey Blvd. After the project some of the residents had questions about the workmanship. On November 8th members of the engineering staff, Council Member McGlone, and Mayor Ramsey met with residents to hear their concerns. Attached to the case is a letter containing a list of those concerns and the city's response. Since that meeting residents have met several more times to discuss the workmanship of the project with council members and staff. On July 9th public works and engineering staff met with residents Barb McKusick and Levi Dargis. After discussing of the project and reviewing the core samples taken at various points in the road, the two major concern remaining seem to be the depth of material at the curb line and the warranty period. Four core samples were taken on the project, with two of them taken in the south curb line one in front of 6828 157th Ln and the other taken at 7020 157th Ln. Both samples average 1-1/2 to 2" in depth approximately 9"-12" from the curb. The other concern was with the warranty period. The warranty period is the standard one year from the city's acceptance of the project. Staff has driven and inspected the curb line on this project and other overlay projects performed last year by the same contractor (North Valley). Staff found no signs of distress in the curb line on any of the projects. Other concerns were with the drainage in the cul-de-sac and the center seam of the road. Mr. Dargis reviewed the repairs made in the cul-de-sac with staff and was satisfied with the curbing and the drainage repairs. The center seam was and remains crooked. The height difference has been somewhat eliminated by snowplowing there is still a slight lip, but not consistently, through the project. Though this seam as not as straight as it should be it, it has no effect on the integrity of the road surface itself. Notification: Affected residents will be notified of the meeting time and location by mail. Observations: Though there are some concerns with the road staff feels the overlay is sound and will perform up to standards. Staff will continue to monitor the road edge for possible problems, but doesn't foresee any at this time. Funding Source: Dependant on discussion Staff Recommendation: Accept the road project and monitor for any defects. If any defects occur, treat as needed, within our routine maintenance schedule. Committee Action: Motion to accept road and let warranty period expire. Letter addressing resident concerns Attachments Form Review Inbox Reviewed By Date
