The Waltham Woods/Reservoir Woods West complex is located on a 170 acre site that is in a highly sensitive watershed that is tributary to a public drinking water supply. Prior to development, approximately 70 % of the site was wooded , and some of the existing storm water systems flowed directly into the reservoir. If the site was to be developed, it had to be demonstrated to various public and environmental agencies that there would be no degradation of water quality discharging to the public water supply.
A strategic master plan was developed which incorporated sustainable natural systems, such as constructed wetlands, wet ponds, pretreatment marshes, filter strips, and level spreaders, as well as traditional structural BMP’s into a Class A office development for 1,800,000 square feet. Approval was obtained from the various agencies to construct the development and the associated water quality systems, which removed 100% of the nutrients, suspended solids, and pollutants from storm water runoff prior to discharging into the water supply.
Currently, 1,400,000 square feet of the development is built , and the water quality systems are performing as planned. The project has been cited on numerous occasions as a model project for protecting water quality within the public water supply.
