Project Description
St.Germain provided civil engineering and local permitting support to the Westbrook Housing Authority. Our senior civil engineer assessed the pre-development stormwater runoff for this urban site located within sight of the Presumpscot River, where existing runoff was directed, and developed treatment options that could be integrated into the site layout.
Working closely with Westbrook Housing Authority, PDT Architects and Great Falls Construction, our engineer utilized stormwater diversion and treatment developed by the University of New Hampshire Stormwater Center. UNH’s Tree Box Filter provides physical, biological and chemical treatment of impacted runoff from paved areas. In the filter design, sediments are physically removed through the soil and fabric filter media, while storm water pollutants, such as nitrogen and petroleum hydrocarbons, are broken down chemically and biologically by vegetation and soil microorganisms. The overall result is an improvement of water quality to the Presumpscott River, which is a vital part of downtown Westbrook and the greater Portland watershed.
While this is a relatively small engineering project, the impacts of this site are large in terms of revitalizing downtown Westbrook in a sustainable manner and working with our team members to ensure the best site possible for our client. Construction on the project is complete and the units are available through Prudential Northeast Properties.
