South Side Drainage Project

Phases I and II are complete and Phase III design is complete. The project is now going through the permitting process with the Massachusetts Department of Environmental Protection (DEP) and other agencies. Permits are anticipated to be complete in March 2022, with bidding to be conducted during the Spring of 2022, followed by construction during the Summer/Fall of 2022. See the Overall Site Plan as of July 30, 2021 (PDF).

An abutter information session was held by the contracted engineering firm and Weston's Town Engineer on August 5, 2021. A PDF of the presentation is available online for review. The meeting was recorded, as well.

Project Background

A study was conducted in 2011 to develop long term plans for drainage improvements to alleviate chronic flooding problems that have plagued the area for many years. Wright-Pierce Environmental Engineering Firm of New England was engaged to complete the study phase of the project, which included data gathering to quantify the size, condition and location of the various drainage systems that serve these areas, as well as interviewing town staff to understand the nature and severity of flooding problems, modeling the hydrology of this area and hydraulics of the systems, and then developing alternative designs for drainage improvements.

The drainage study of the area included:

  • Glen Road
  • Ledgewood Road
  • Pond Brook Circle
  • Shady Hill Road
  • Wellesley Street
  • Woodchester Drive


The project is being overseen by the Department of Public Works, Engineering Division, working with Wright-Pierce Environmental Engineering Firm of New England.
