The Town of Medway received a $1.625 million Cooperative Agreement from the U.S. Environmental Protection Agency (EPA) Region 1 under the Congressionally Mandated Projects program (CFDA 66.202), awarded January 1, 2026 and extending through February 27, 2027. The award funds the design and construction of green stormwater infrastructure (GSI) stormwater control measures at two municipal sites—Medway Middle School and Medway Senior Center—to improve Charles River water quality by reducing pollutant loads, particularly phosphorus, which contribute to harmful algal blooms and ecosystem degradation.

The project deliverables include the implementation of up to two of five evaluated GSI techniques, including bioretention basins, biofiltration basins, and subsurface infiltration chambers installed on town-owned properties. Work activities involve removal of impervious surfaces and installation of these green infrastructure systems to treat stormwater runoff, mitigate localized flooding, and build municipal capacity to address escalating runoff issues in the Charles River watershed caused by urbanization. No sub-awards are included in this assistance agreement; all activities will be performed directly by the Town of Medway.

This agreement provides funding to the town of medway to implement its project to construct green stormwater infrastructure (GSI) stormwater control measures (SCM) at the medway middle school and medway senior center sites for the purpose of improving water quality of the charles river by reducing the levels of pollutants, including phosphorus, which contribute to harmful algal blooms and degraded aquatic habitats. Using GSI techniques that mimic natural filtration and storage processes will treat stormwater and build capacity to address localized flooding, as directed in the 2023 consolidated appropriations act. Activities:the activities to be performed include the execution and implementation of green stormwater infrastructure stormwater control measures to address the escalating stormwater runoff issues caused by urbanization within the charles river watershed. The increasing volume of runoff carries pollutants, including phosphorus, which degrade water quality and harm downstream ecosystems. Phosphorus contributes to harmful algal blooms that deplete oxygen levels in the river and threaten aquatic life. Workplan activities consist of the removal of impervious services and incorporating green infrastructure, including the advancement of up to two of five recently evaluated new and retrofit GSI scms, including bioretention basins, biofiltration basins, and subsurface infiltration chambers on town-owned properties to achieve water quality and quantity benefits and build capacity to address inland flooding. Subrecipient:no subawards are included in this assistance agreement.outcomes:the anticipated deliverables include the construction of green stormwater control measures at both the medway middle school and medway senior center sites, which are expected to lead to the improvement of water quality in the receiving waters that ultimately discharge to the charles river.
