  • 2023 Paving Program (Updated June 1, 2023):  Schedules will be posted here when available. The Town uses several methods to surface or resurface the roads. Descriptions of these treatments can be found on this document. Please see the  2023 Paving Map which is color coded to show the particular type of treatment on each road on this years' list.  Any questions or concerns should be directed to the Paving Hotline: 781 274-8905
    • Surfacing Contract Update:  Asphalt patching and crack sealing will begin the week of 6/5 on various streets. There will be no road closures associated with this work, however alternating traffic and minor delays may be necessary. Other low impact prep-work will be taking place throughout the month of June. Microsurfacing treatments which will cause short term road closures are anticipated for the middle of July. Fog Sealing is anticipated for August. Schedule will be updated here as more information becomes available. Please contact us with any questions. 
    • Traditional Paving Contract Update: Preliminary work has begun. Drainage work in advance of paving operations is underway.

  • Valleyfield, Grassland, and Waltham Streets Drainage Improvements Project (Updated March 3, 2023) The project includes storm drain improvements, culvert replacement, and related work on Valleyfield Street, Grassland Street, and Waltham Street near Brookside Avenue. Also included in this project is the traffic lights upgrade on Waltham Street at Brookside Avenue. Any questions can be directed to the email of Marissa Liggiero.
  • Oxbow Road and Constitution Road Drainage Improvements Phase 1 (Updated December 20, 2022) Kiln Brook Culvert Daylighting Project includes drainage improvements in front of 27/29 Constitution road and includes daylight an existing outfall, installing a culvert, roadway infrastructure improvements and wetland improvements. Phase I is now complete and being monitored. Phase II is expected to take place in 2023. This phase will include increasing drainage pipe sizes on Oxbow Rd, and installing a new section of drain line and drainage structures on Oxbow and Constitution Rd. Minor traffic implications are expected during construction. Plans and more project information will be available soon. Please email Matt Weisman or email Ross Morrow if you have questions in the meantime. 
  • Sewer System Improvements (Updated May 5, 2023) This project, over many phases, includes sewer repairs and rehabilitations for both structural and infiltration related defects. Infiltration is clean water from below the ground (groundwater) that enters the sewer system through defective pipes and structures. This “clean” water takes up valuable space and capacity in the sewer pipes that would normally be available for wastewater. It can cause the pipe and service conditions to back-up and potentially overflow during extreme wet weather conditions, and it costs the Town’s sewer rate payers money to send this “clean” water to the MWRA system. In order to correct many of these issues, repairs and rehabilitations are being made as part of this project. We will update the website once scheduling has been set for this construction season. Any questions or issues can be directed to Marissa Liggiero at
    • Phase 8
      • Done

This project has wetlands/groundwater and slope challenges. The contractor, DeFelice, plans to start construction on March 20, 2023. Please use caution when driving past the job site. Any questions or issues can be directed to Marissa Liggiero at
