Retention/settling ponds, rain gardens, bioswales, erosion control where soil is disturbed.
Has the institution adopted a rainwater/stormwater management policy, plan, or strategies that mitigate the rainwater runoff impacts of ongoing campus operations through the use of green infrastructure? :
A brief description of the institution’s rainwater/stormwater management policy, plan, and/or strategies for ongoing campus operations:
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 new vegetated bioswale. Two rain gardens capture rain water and sidewalk runoff prior to reaching the storm sewer. 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.

Rainwater harvested directly and stored/used by the institution, performance year:
