When a new CVS/pharmacy® store was slated to come to Highland Plaza in Holbrook, Mass., the development site required a number of design changes and upgrades.
Three firms came on board to bring the improvement ideas to life. Reeves Design Associates was responsible for the site architecture; BKA Architects, Inc. designed the CVS/pharmacy; and R J O'Connell & Associates, Inc. took charge of the engineering aspect of the redevelopment.
Stormwater upgrades to the entire site were a key part of the project. An existing stormwater system, which consisted of catch basins and pipe, connected to the Massachusetts Highway Department (MassHighway) drainage system running along Route 37.
In addition to replacing the connecting pipe, the R J O'Connell & Associates engineers had to provide 6,177 cubic feet of detention storage for the 4.4-acre site. In cases where all the stormwater needs to be kept onsite and the development area needs to be maximized, the engineers have traditionally used subsurface chamber systems provided by CULTEC, Inc. This time, the engineers selected the low-profile Recharger® 150 HD unit from a variety of available chamber sizes.
The detention system was installed in 10 rows, each 16 pieces long, and occupied about 6,200 square foot of underground area, leaving the above-ground surface for parking. An in-line side portal manifold eliminates the need for a costly external pipe header. T
The manifold also makes the system’s installation easier than that of a conventional manifold system. Additionally, CULTEC’s systems use less stone than other comparable systems on the market and require no heavy installation equipment. At Highland Plaza, excavation, installation and backfilling took about a week, making for a speedy completion of the site’s drainage system.
