F | Consideration and Approval of Contract: Annual Street Maintenance and Overlay Program 2019 | ||||||
Streets Section Director Scott Overton provided a PowerPoint presentation that covered the following: STREETS OVERLAY 2019 PROGRAM PROGRAM OVERVIEW Councilmember Whelan asked why the Construction Manager at Risk (CMAR) option was selected for an overlay project. Mr. Overton explained that the project is currently in the middle of a three-year CMAR program, this is the third and final year on the current contract. It has been a good relationship with the vendor and staff is pleased with the outcome of their work. The CMAR process may change for future programs. Councilmember McCarthy asked how long the overlays typically last. Public Works Senior Project Manager Adam Miele explained that the time depends on the classification of the road. The average for traditional overlays is four years and the City has been able to typically get a few more year due to the type of asphalt mix that is used; in general it is not unusual to get up to ten years. Councilmember McCarthy asked if the material that is removed from the road in preparation for overlay is reused in any way. Mr. Miele stated that the material is used to build up shoulders, rebuilding of dirt roads, and other similar operations. Councilmember Odegaard asked how roads are determined for chip seal or overlay. Mr. Miele stated that there is no set equation as to when chip seals and overlays occur because it is so dependent on how much the road is used as well as the freeze thaw cycles that Flagstaff experiences. There is a yearly evaluation and ranking of road conditions to determine the best method necessary. Mr. Overton stated that they try to put off overlays as long as possible since they are able to get such good results from the chip seals. Since Proposition 406 passed they have completed 108 miles of overlay and 317 miles of chip seal. Moving forward they have programed dedicated maintenance money all the way through the end of the Proposition 406 term with the intent of catching up in the first five years and then preserve with proper maintenance from year six through twenty. Vice Mayor Shimoni asked if there was anything that could be done to create more space for bicycles. Mr. Overton stated that they work with traffic engineering to partner on projects for a complete street rebuild which could include bike lane components. |
