Landfill Assessment, Excavation and Roadway Construction
City of Attleboro
Challenges:
The City of Attleboro’s downtown redevelopment efforts have been centered around a new Intermodal Transportation Center for commuter rail and bus services. A bike path/greenway along the Ten Mile River is also part of the project. A key component of the downtown redevelopment project includes a new road connecting two major thoroughfares to direct traffic efficiently away from the transportation center. This road traverses several sites that are being managed under a Special Project permit approved by MassDEP, including a commercial landfill and an older municipal landfill. To enhance the stability of the road, soil and debris were removed down to nine feet.
Solutions:
Because a number of utilities were installed beneath the road and the depth of some of the utilities extended below the water table, soil and groundwater management was necessary. ES&M prepared a RAM Plan to facilitate appropriate management of soil and groundwater during construction. During excavation, ES&M directed soil segregation into appropriate stockpiles and conducted a soil sampling program to determine the most appropriate disposal options. Approximately 8,000 cubic yards of soil and debris were removed. Once the soil was characterized, we oversaw a program to segregate the soil from rocks and debris, in order to reduce soil disposal costs.
ES&M also implemented an extensive dewatering program during construction. We designed and built a water treatment system that was operated under the provisions of the US EPA Remediation General Permit MAG910000. ES&M personnel operated, monitored, and maintained the treatment system to ensure that all discharges met permit limits.
