Peabody Square is located in the Ashmont section of Dorchester at the intersection of Dorchester Avenue, Ashmont Street, and Talbot Avenue. Historically, the square has served as a commercial district and provides a major public space adjacent to the Ashmont T Station. South Dorchester is bordered to the east by Dorchester Bay and to the south by the Neponset River.
The site is comprised primarily of commercial and high-density residential land uses and consists largely of paved areas including roadway, parking, sidewalk and plaza. The site area drains into the Neponset River, which is on the Massachusetts 303(d) List of Impaired Waterways for organics, pathogens and turbidity - all common pollutants in stormwater runoff.
Prior to the start of the project, the site was slated for a redesign to improve traffic and pedestrian circulation through the intersection, therefore, the project stakeholders recognized the opportunity to incorporate green infrastructure in to the redesign. The project reconfigured the street intersection design to make it more pedestrian friendly and incorporated a number of stormwater management practices; namely a pedestrian plaza with porous pavers, a rain garden and an infiltration trench for treating runoff from adjoining roadway; which will improve water quality for nearby receiving waters.
