Shadley Associates recently worked with the City of Lawrence, the Massachusetts Valley Regional Transit Authority, Groundwork Lawrence and a large team of consultants on the Lawrence Gateway project. While other consultants were responsible for a 975 car parking area to spur economic development of 1.2 million square feet of mill building space, Shadley Associates led the Oxford Park team for the creation of a new 2.8 acre public park at the intersection of the mill raceways and the Spicket River. This site has contaminated soils (asbestos and PCB’s), remnants of raceways and building foundations, and needed to accommodate several hundred thousand cubic feet of flood storage for the Merrimack River. The park plan created by SA accommodates these requirements and creates a new, naturalistic park whose main walkway is a critical link in the Spicket River Greenway. The park plan caps the contaminated soils, accommodates flood storage in massive underground chambers, creates an informal sloped performance area, provides universal accessibility through 16 feet of vertical grade change, works with the adjacent new parking area and the new MassDOT Canal Street Bridge, and revegetates the site and opens it to the public. Construction was complete in 2014.
