MINUTES OF THE ORONO CITY COUNCIL MEETING Monday March 13,2017 7:00 o'clock p.m. 4. FOX STREET REHABILITATION — APPROVAL TO SOLICIT BIDS - Continued - Martini detailed the condition of Fox Street between Old Crystal Bay Road and Willow Drive, noting that the pavement width varies between 21 feet and 23 feet in different areas, with the overall condition of the pavement being in pretty poor condition. This section of the road sits on clay subgrades and also some swamp composites. As you get closer to Brown Road near the bridge, there are some poor soils that the road is constructed on. Pavement depth varies between five inches and six inches. The aggregate base ranges from a couple of inches to up to four feet. Martini stated the road has existed for a long time and has been maintained at various levels throughout the years. Martini explained the proposed improvements will be similar to the reconstruction project completed on Watertown Road and will consist of a complete reconstruction of the pavement and subgrade, putting in new culverts, and installing geotechnical fabric. In addition, the bollards will be replaced with guardrails and associated stormwater system repairs will be made. On the MSA section of the road, the pavement will be widened to 22 feet wide, with a I -foot gravel shoulder to help protect the road and to provide drivers with some recovery area if they drift off the paved section. The anticipated total cost for both sections of the project is $1.1 million dollars. Section A, which is the City -funded portion of the road, has an estimated cost of $617, 604. The state aid portion of the road has an estimated cost of $489,982. Martini noted the current estimates are below what was originally estimated in the feasibility study. The stormwater improvements are estimated at $43,057. Martini stated the main difference between the numbers contained in the CIP and today's anticipated numbers are the soil corrections. Originally it was thought there would be some settlement of the subgrade that would need to be addressed but it is now felt that the soil has settled sufficiently given the age of the road. Martini outlined the anticipated schedule for the project. If the Council authorizes the solicitation of bids tonight, the bid opening will be April 18, with the project being awarded at the April 24 Council meeting. Construction would begin the summer of 2017, with a September I completion date. Martini stated the Council could elect to begin construction earlier in the spring, with an August 4 completion date, but that his recommendation would be to start the project after school is out to avoid the need to coordinate the work around the school bus schedule. Seals asked if there is a cost difference between the August 4 completion date and the September I completion date. Martini stated basically they would be giving the contractor the same amount of time to get the work done and that there likely would not be a cost difference. Martini indicated starting the work while school is still in session would create some logistical issues with the buses coming and going. Martini stated his preference would be to not have to coordinate that but that it is up to the City Council. Printup asked if the gravel shoulder is required by MSA. Martini indicated the City has to have a 24 -foot portion, which is the reason for the I -foot gravel shoulder on either side. Martini stated generally vegetation will grow into the gravel but that it is nice if a tire goes off the paved roadway. Martini stated he would prefer to be able to have a gravel shoulder on the City portion as well but that the width is very tight in there given the existing conditions. Page 2 of 32
