Which of the following best describes the institution’s approach to rainwater management?:
No written policies, plans or guidelines, but green infrastructure and LID practices are used
A brief description of the institution’s green infrastructure and LID practices:
Retention/settling ponds, rain gardens, bioswales, erosion control where soil is disturbed.
1) East of Prince Conference center there are a series of three retention ponds that capture parking lot runoff and allow for evaporation, plant material processing and ground penetration
2) The Seminary pond is a settling/retention pond with a natural planting area before the inlet to slow down the flow of water from the CFAC parking lot, south dorms much of center campus and other surrounding areas.
3) The two ponds by the lower athletic fields are separated by a berm with a sea wall. Water is routed to the first pond where sediment settles, and slowly passes through pipes in the sea wall to the second pond where there is an outlet if the water level gets too high.
4) The nature preserve bioswale catches water from parking lot 13 and uses plant material to process the runoff.

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:
Rain/storm water from many areas of campus is diverted to one of four retention ponds prior to reaching storm sewers. One of the retention ponds has a vegetated bioswale before the inlet. The large student lot by the nature preserve drains into a vegetated bioswale. Two rain gardens capture rain water and sidewalk runoff prior to reaching the storm sewer. A third curb-cut rain garden in the Knollcrest East apartments helps address standing water after rain events. A fourth rain garden treats runoff at Bunker Interpretive Center. Construction projects have erosion fence installed from the beginning until final site work is performed. Catch basins are also fitted with runoff protection. Erosion blanket or mulch is applied to stop erosion whenever site work is performed.
