TEC led the design of the Proposed Site Development at 423 Merrimack Street in Lawrence, MA. The project included the construction of a convenience store with a filling station, restaurant, drive-thru, office space, and a car wash. TEC worked with various entities in obtaining all necessary permits for the project which included a Special Permit from the Zoning Board of Appeals, a Notice of Intent with the City of Lawrence Conservation Commission and MassDEP, Site Plan Review approval from the City of Lawrence Planning Board, and a State Highway Access permit with MassDOT.
Site related tasks for the project included designing stormwater best-management practices such as deep-sump and hooded catch basins, water quality units, and a subsurface detention system to reduce peak flows and improve the water quality of runoff generated by the impervious surfaces.
Other site related tasks for the project included designing and coordinating utility connections to the site through a complicated web of existing utilities such as water, gas, sewer, and electric. This was a crucial step in the success of the project due to the age of the existing utility infrastructure to be utilized on site and the presence of “unknowns” in the subsurface. The proposed uses required the use of multiple oil/water separators and grease traps to adequately treat the wastewater generated before connecting to the City’s sanitary sewer.
The construction phase of the project saw TEC being responsible for coordinating with contractors on tasks such as preparing sketches for RFIs, approving shop drawings, and overseeing and inspecting construction activities.
