CAPITAL EXPENDITURES COMMITTEE REPORT TO 2016 ATM Roads Lexington has a total of 199.6 miles of roads, which include State and unaccepted roads. This total consists of 135.0 miles of Town - accepted roadways, 18.5 miles of private /unaccepted roadways, and 46.1 miles of State highway. (Source: Fay, Spofford & Thorndike (FST) report, October 27, 2015.) The DPW maintains the public, Town - owned, roadways; the remainder being maintained by the private owners or the State. The DPW also maintains the Town's portion (5.3 miles) of the 10.0 -mile Minuteman Commuter Bikeway ( "Bikeway "). In April 2010, the Town retained FST, a civil - engineering consulting firm, to develop and implement a Pavement Management System (PMS) for its public roadways and its portion of the Bikeway. The first study was completed in November 2010 and has been updated annually. The PMS is based upon an extensive roadway database describing pavement conditions and roadway characteristics, and among other things reports conditions using a Pavement Condition Index (PCI), which is a 100 -point scale with 100 representing the best possible condition. Using the October, 2015, update, from 2014 to 2015, the Town's PCI continued to improve, from 73.9 to 74.9. The 2015 74.9 PCI signifies that the majority of streets are within the "Routine Maintenance" band. The initial study reported the replacement cost for just the Town - accepted roadways would be in excess of $85 million in FY2011 dollars (a more detailed analysis of the report is contained in this Committee's report to the 2011 ATM, beginning on Page 21). The 2015 FST update states "Lexington is in a very good place from the Pavement Management perspective with 75% of the Network in the `Do Nothing' and `Routine Maintenance' treatment bands. However, the report goes on to caution that `future funding scenarios are showing that the budget will not keep up with the expected deterioration of the `Structural Improvement' candidates as the backlog increases significantly when these segments trickle into the `Base Rehabilitation' treatment band." FST has recommended the Town secure at least $3.5 million this fiscal year in order to continue progress in all treatment bands. The Committee remains extremely pleased to see a quantitative basis for determining the condition of the Town - maintained pavements. This Committee also supports the DPW's continuing efforts to raise the Town's baseline pavement condition grade to "above average." Implementation of the PMS, along with DPW management of other potential impacts to our pavements (e.g., utility work, construction for storm -water and wastewater system improvements, sidewalk - related projects, etc.) offers the promise of an even more productive and cost - effective program going forward. Funding for roads is provided by a combination of State Chapter 90 funds and Town funds. (See Article 10(c & g)) Sidewalks The town has over 84 miles of sidewalks. In 2005, due to the overdue need to upgrade and extend the sidewalks, the BoS appointed the Sidewalk Committee. In 2014, the DPW with assistance from FST (its report, December, 2014), completed a sidewalk - condition survey. The survey results found that "the average area -based Sidewalk Condition Index (SCI) in Lexington was 68 (an 80 to 100 score is "do nothing "), which puts it in the middle of the Localized Repair treatment band. The survey also found 40% of the sidewalk network in the `Do Nothing' treatment band and 34% in the `Localized Repair' treatment band... ". The FST survey recommendation was that it would require $750,000 to maintain current conditions, but would require $825,000 on sidewalks and ramps to ensure both quantity and quality. The proposed DPW sidewalk replacement program is based upon the priority list developed in conjunction with the survey. Sidewalk replacement and extension are costly initiatives. Imbedded in these costs are sidewalk - construction obstructions, easement issues, and negotiations with residents. The Sidewalk Committee's overall policy has been to develop a prioritized sidewalk - construction plan focusing on the "Safe Routes to School Program ", other high - pedestrian - traffic routes, and high — walking- hazard streets. All reconstructed/new sidewalks are designed and constructed to comply with the Americans with Disabilities Act (ADA)." This Committee is pleased that funding requests for center - business - district (CBD) sidewalks are presented separately from those for residential sidewalks and that there are now three sidewalk categories 18
