Item No. 9 memorandum TO: Mayor & City Council FROM: John Godwin, City Manager SUBJECT: STREET BOND IMPROVEMENTS PROGRAM DATE: June 30, 2017 BACKGROUND: We have created a prioritized list of 22 street segments that have been identified as most needing reconstruction to one degree or another. As I described during the election cycle, these are not necessarily the streets with the absolute worst pavement in the city, but all are collector streets, so their reconstruction will impact the most overall traffic. Each is an asphalt street, and each will be replaced with asphalt. Some will necessarily include sidewalk, drainage, and utility work. Obviously we do not want to rebuild a roadway only to leave behind drainage problems, or have it dug up when a water or sewer line breaks. ADA comes into play with some sidewalk requirements. STATUS OF ISSUE: Most of the streets will be rebuilt using a construction practice called mill & overlay (or inlay). This is the type of work that was done on Collegiate in 2016, and is suitable for roads with adequate bases. Other roads will require full -depth reconstruction, a more expensive construction process that also includes significant engineering costs. Two roads, 33`d SE and Collegiate between Clarksville and Lamar, fall somewhere in a middle ground where full -depth would be preferred but not absolutely necessary. By doing only mill & overlay there, coupled with some new curbing and other improvements, we will get a much better driving surface that should last many years, while saving money to complete more projects. Attached is a draft three -year plan, showing all of the proposed streets. Year one includes four mill & overlay projects that can be done quickly and without outside engineering. They also have what we believe to be good utility structures under them, so we can proceed this calendar year. Also we will do in -house utility work on Graham so that it will be ready for repaving in 2018. Finally, we will hire an engineer to begin design on a full reconstruction of Church Street, work on which will occur in 2018. All of the 22 segments will likely not be able to be funded. BUDGET: Funding will come from 2017 bond proceeds, anticipated in late August. RECOMMENDATION: Direct staff to proceed with plan, along with any changes agreed to.
