Yesterday’s groundbreaking of Shaffer Paper Park celebrated the highly anticipated transformation of the 15-acre former industrial site along the Neponset River. The design strategy, which includes efforts to remediate contaminated soils, restore ecological habitat, and create a neighborhood open space for the community of Dorchester, was a collaborative effort between Halvorson Design, the state Department of Conservation and Recreation (DCR), GEI Consultants, and DeRosa Environmental Consulting.
