CAPITAL EXPENDITURES COMMITTEE REPORT TO 2022 ATM& STMs 2022-1 & -2 Public Works The Department of Public Works (DPW) is responsible for design, bidding, construction, and project management related to Town infrastructure, including buildings assigned to the Department of Public Facilities (DPF). Routine maintenance and other operational activities are not capital-related and are not addressed by this Committee. The DPW is organized around seven divisions that are responsible for: Administration, Engineering, Highway, Public Grounds, Environmental Services, Water, and Sewer. The Environmental Services division manages solid waste, recyclables, yard waste from Lexington and private contractors, and hazardous products from Lexington and eight neighboring communities. Major components of DPW's FY2023–FY2027 capital projects include: • Road, sidewalk, and signalization improvements • Water distribution, sanitary sewer, and pump-station upgrades • Hydrant replacements and parking lot improvements • Town Water Towers major repairs or replacements • Comprehensive Watershed Stormwater Management improvements • Storm Drainage and National Pollution Discharge Elimination System (NPDES) improvements • Hartwell Ave. Long-Range Transportation Improvement Planning • Trucks and heavy equipment necessary to accomplish the DPW mission A 5-year history of DPW capital appropriations appears at the end of this section; the CEC's 5-Year Capital Plan can be found on Page 11. DPW's capital needs—except when funded in whole or in part by the Town's Community Preservation Fund, Revolving Fund, or Enterprise Funds—must be funded by cash or financed through the general tax levy and/or voter–approved debt exclusions. Almost all construction projects for the sanitary-sewer system and for the water-distribution system are funded by Water- and Sewer-rate payers through the Enterprise Funds. Large trucks and heavy equipment used in support of the sanitary-sewer and water-distribution systems are also funded, either in whole or in part,by Enterprise Funds. Engineering Engineering work for all DPW projects is either done in-house or contracted through public procurement to outside consulting or design firms. In addition to supporting ongoing DPW work, Engineering is a major participant in DPW's future projects. The simple title of this Division does not reflect its enormous and crucial contributions across the breadth of the DPW's capital and operational activities. Roads Lexington has almost 200 miles of roads, which include Town, State, and unaccepted roads. This total consists of 131 miles of Town-accepted roadways (TAR), 18.5 miles of private/unaccepted roadways, and 46 miles of State highway. (Source: Stantec FY2017 Asset Management Summary, January 2017). The DPW maintains the TAR;the remainder are maintained by the private owners or the State. The DPW also maintains the Town's portion (5.3 miles) of the 10-mile Minuteman Commuter Bikeway (`Bikeway"), which opened in 1993. In Apri12010, the Town retained Fay, Spofford&Thorndike (since acquired by Stantec), a civil–engineering consulting firm,to develop and implement a Pavement Management System (PMS) for the TAR and its portion of the Bikeway. The first study was completed in November 2010 and has been updated annually. The PMS is based on an extensive roadway database describing pavement conditions and roadway characteristics, and originally reported conditions using a Pavement Condition Index (PCI), which is a 100-point scale with 100 representing the best possible condition. The Town has since changed to a new software system that uses the term Road Surface Rating (RSR) rather than PCI, and a new contractor (BETA Group) to do annual updates. The first BETA update, for FY2018, showed the average condition for the TAR continuing to improve, from a PCI of 77.0 the previous year to an RSR of 79.33. The Town's modeling of the entire road network found that the RSR 21
