Site work for a water / sewer project in Lexington, Massachusetts. Conceptual plans call for site work for a water / sewer project.

This program was created in FY2025 to combine three former programs - Townwide Culvert Replacement, Storm Drain Improvements and NPDES Compliance, and Comprehensive Stormwater Management - into one annual stormwater management request. Many of the challenges and solutions are multi-pronged and cross over between the three programs, which creates complications in the selection and awarding of projects. By combining these projects, it creates more flexibility and agility for the Department for the improvements of stormwater throughout Lexington. The aggregated funding will be utilized for supporting the National Pollutant Discharge and Elimination System (NPDES) program with an emphasis on Illicit Discharge Detection and Elimination (IDDE) and nutrient removal which are both required by the Environmental Protection Agency (EPA) Municipal Separated Storm Sewer System (MS4) permit. These regulations are focused around improving water quality. Additionally, this request will support the stream management plan, culvert replacement and rehabilitation program, and storm drain improvements to mitigate flooding. In FY2027 work will continue on MS4 compliance, and may include phosphorus removal, drainage investigations, and drainage improvements. The project is included in the City's 2027 Capital Improvement Program (CIP). As of July 29, 2026, further details have not yet been identified. *Project information has been obtained through a public capital improvement plan (CIP). A CIP is a financial schedule for short- and long-range projects which is updated regularly. Information listed in the CIP often evolves based on funding availability and the project details, including timeline and value, are subject to change. The content management team will continue to pursue additional details as they become available.
