Region 1: EPA New England
Providence Green Infrastructure Project
The United States Environmental Protection Agency (EPA) is partnering with the City of Providence, the Rhode Island Department of Environmental Management (RIDEM) and other stakeholders for a project to construct a bio-infiltration system at J.T. Owen's Park near Mashapaug Pond. Bio-infiltration is a green infrastructure (GI) best management practice (BMP) for stormwater control. Green infrastructure is stormwater management approach that takes advantage of natural processes to capture and treat stormwater volume and pollutants. The Mashapaug project is a retrofit project and will include a public outreach component to showcase the project and engage the community.
An important goal of this project is to introduce municipal officials and other public and private stakeholders to GI as a practical and effective technique to reduce stormwater runoff and pollution and improve water quality.
We anticipate that the bio-infiltration BMP will:
- lead to improved water quality in Mashapaug Pond;
- increase public and private awareness of GI as an effective approach for municipal stormwater management;
- engage and educate local department of public works engineers and other municipal officials how GI can be a viable and effective control for stormwater;
- engage Project Partners to understand and implement operation and maintenance (O&M) procedures to ensure the BMP continues to operate into the foreseeable future.
The bio-infiltration BMP will be constructed on the J.T. Owens Park, which is situated on Mashapaug Pond, a waterbody listed as impaired for nutrients. The Pond feeds into Roosevelt Lake, part of the interconnected pond system created in Roger Williams Park at the end of the 19th century, and its input contributes to severe water quality problems in those ponds as well. The bio-infiltration BMP will be sited adjacent to the existing Little League baseball fields which are located near Mashapaug Pond.
Construction of the bio-infiltration BMP will entail installing a diversion structure into the storm sewer line located near the Niantic Ave and Swanson St. intersection and diverting an approximate 1 to 1.2 inches of water to the bio-infiltration retrofit located at the southern/far edge of the Little League ballfields. The BMP will treat runoff from approximately 6.5 acres, including about 2.6 acres of impervious cover that would ordinarily discharge to Mashapaug Pond, an impaired waterbody with a TMDL.
