Stormwater Utility


Stormwater Utility Fee

The Town of Wellesley is considering a Stormwater Utility Fee to meet increasing demands associated with the Town’s stormwater management program. Wellesley is facing federal requirements to reduce the amount of pollution from stormwater runoff discharging to waterways, including substantial phosphorous reduction requirements of runoff into the Charles River. Consequently, the Town must increase investment in stormwater infrastructure management to meet permit obligations.

A Stormwater Utility Fee is a mechanism to fund this required investment. A fee is developed based on the amount of hardened or impervious surface, such as parking lots, driveways, and buildings, which contribute to stormwater runoff on a given parcel. Similar to water and sewer utilities, a stormwater utility allocates costs based on the amount of use, or in this case, amount of impervious surface. The allocation of fees in this manner is an equitable method of distributing stormwater management costs.

Advantages of a Stormwater Utility Fee include:

  • Sustainable – dedicated, stable revenue source
  • Equitable – based on stormwater impact vs. property value
  • Flexible – Enterprise will fund all aspects of the stormwater management program
  • Credit policy – Part of the stormwater utility development can include a credit policy. This credit policy can create a financial incentive for stormwater improvements on private property. 

The generated fees will be used to comply with permit requirements, maintain and replace drainage infrastructure, flood prevention, and to protect waterbodies from harmful stormwater pollutants. 


Wellesley is currently developing the framework of a potential Stormwater Utility Fee. Prior to adoption of a stormwater fee schedule, a Stormwater Enterprise Fund will be proposed at  Special Town Meeting in 2022.  An Enterprise Fund is a best practice to promote and maintain the long-term financial sustainability of the stormwater program
