No

A brief description of the institution’s Low Impact Development (LID) practices:

All construction has met DEP permitting requirements for stormwater management but not LID practices This has primarily included constructing proper drainage and filter systems around new construction. Our current permit includes the creation of a retention pond that was be sized appropriately to treat all current campus stormwater and any foreseeable addition from construction in keeping with the Campus Master Plan.
