Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:

Low impact development and storm water control is a priority for the college especially since local, state and federal laws dictate proper management. Further, the college is located within a stressed water basin and maintains its own potable water system drawing from our own wells located on campus.

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

The campus has several large storm water interceptors and multiple sedimentation bays, including the Cattail Marsh, for high storm events. Most storm water is treated before it enters Lake Waban by removing sediments and oils. Where feasible we also put this into vegetated swales and retention basins. These are preferred by the college since they not only trap sediments and oils but also limit the amount of phosphorus entering adjacent waterways. Where vegetated swales are not feasible the college utilizes “vortechnic” type mechanisms. We incorporate bell hoods in catch basins in sensitive areas to capture oils and fuels. Where feasible we reduce impervious surfaces which would include reducing paved areas, incorporation of green roofs, and efficient management of stormwater run-off. We have removed over 5.7 acres of asphalt over the past 10 years. Lastly, we implement storm water best practices management (BMPs) for new and renovation projects. Storm water management is extremely important to the college because we are in the Charles River watershed.
