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.
