Minutes of the Lexington Capital Expenditures Committee (CEC) Meeting November 15, 2016 those damaged during a traffic accident (which are reimbursed, if applicable); and those identified for replacement during the flush-and-inspection program. Both the DPW and the Fire Chief are comfortable with the progress using this approach. Fire hydrants have a 50-year life span, while the TownÓs program incorporates a 20-year replacement cycle. Committee requests: More information regarding the use of the FY2015 funding as the CIP identifies that 346 hydrants have been replaced as part of this programÏwith the cost being approximately $2,500/hydrantÏbut that is only 18 more hydrants than were reported as having been replaced in last-yearÓs CIP. Advice of any non-working hydrants that would have been used when the Fire & Rescue Department responded to an incident. #529 Pump Station Upgrades: The main-station repairs that were required to eliminate a pounding noise in a force main that was disrupting a neighborhood have been completed. The project included installation of variable-frequency drives, a storage tank, and automatic air-release valves. Abutters recently received a final update and appear to be satisfied. Pump stations have a communication system that remotely reports pump failure, generator use, and flow data. Progress continues under the plan so that all stations currently without a backup generator will have one. The Committee requests: A copy of the final update letter sent to the abutters of what had been that noisy force main. Photos taken of the main-station repairs. #554 Street Acceptance: Eight of the 15 Harbell Street abutters have requested acceptance of that street as a public way under the betterment process. The project involves paving 645 feet of roadway. Assuming the project is funded, the $147,000 will eventually be refunded by the betterment payments charged to all of the Harbell Street residents over a period not to exceed 20 years. The additional roadway would result in a minimal increase in the Chapter 90 roadway funds that the Town receives from the State. #557 Comprehensive Watershed Stormwater Management: As discussed above, this project needs to be kept separate from #523. #560 Water Distribution System Improvements: A consultant is developing a hydraulic model of the TownÓs system that will help analyze pressure/volume issues and generate futurefailure likelihood based on replacement history and age of equipment. The initial modeling should be completed this winter and will be periodically adjusted as updated data become available. It is expected to help identify the need for water restrictionsÏwhether voluntary restrictions asked by the Town or formal bans issued by the MWRA. The Town is developing an education program regarding water usage and is working with the Town of Bedford regarding its water draws from the Lexington system. The Committee requests: Verify the numbers of miles of water pipe and of those already lined. #644 Sidewalk Improvement: This was recently updated to include additional funding for sidewalks as requested by the Board of Selectmen (BoS)Ïthat had also been recommended by this Committee. The Committee requests: A list of sidewalks planned to be renovated in FY2018, including the linear feet of each and the total for the list. Page 3 of 6
