STORMWATER MANAGEMENT BYLAW AND FUNDING

Last week, Town Meeting voters approved both the new Stormwater Management Bylaw and funding up to $400,000 through the State Revolving Fund (SRF) at a 2% interest rate. The state loan had been approved subject to Town approval at Town Meeting and then at Town Election. Both of these are required elements of the U.S. Environmental Protection Agency's (EPA) National Pollution Discharge Elimination System (NPDES). Town Election is Tuesday, May 10.

The SRF funding will be used for a number of projects. These include, but are not limited to, the following:


  • Mapping -- The existing Town-owned stormwater management system (i.e. catch basins, manholes, culverts, detention basins, leaching galleys, etc.) will be mapped in Geographic Information System format. In the process of creating these maps, an added benefit will be the creation of a new set of Assessor's Maps. 
  • Inspections -- All elements of the Town system will be inspected to determine its condition and to identify possible illicit discharges.
  • Sampling --  The water discharged from all outfalls will be sampled in both dry and wet conditions. This will help determine where additional treatment or system upgrades are necessary.
  • Pollution Prevention --  A stormwater pollution prevention plan will be prepared for all regulated Town facilities including the Police and Fire Stations, CMD Garage, Town Hall, and Library.
  • Operation and Maintenance -- An operation and maintenance plan for the stormwater system will be developed.
  • Phosphorus Management -- Phosphorus has become a pollutant of increasing concern because it encourages excessive plant growth and results in an imbalance in surface water ecosystems. A plan to address phosphorus discharges will be prepared.
  • Identify Grants -- Grants may be available to help offset the costs of the program and/or to fund improvements to the stormwater management system. Such grants will be identified as part of the program.
Protection of both surface and groundwater resources is critical to the future of Sherborn, and has therefore always been a high priority. This program is the next step in our ongoing effort to protect these resources.
