Does the institution use Low Impact Development (LID) practices as a matter of policy or standard practice to reduce rainwater/stormwater runoff volume and improve outgoing water quality for new construction, major renovation, and other projects?:
Yes
None
A brief description of the institution’s Low Impact Development (LID) practices:
1. A cistern on the roof of the School of International Service (SIS) collects water for flushing toilets within the building.
2. Two bioretention ponds at SIS collect and slow stormwater runoff on either side of the building before filtering it and ultimately allowing excess water to enter the stormwater system through a Bay Saver.
3. Green roofs now span 9 buildings.
4. A rain garden in front of the Kogod Building captures run-off rain water and uses a Bay Saver. A rain garden outside of the Centennial Parking garage captures runoff. Parking has been removed between Clark and Roper Halls and replaced with rain gardens. There is also a rain garden behind McKinley.
5. Pervious pavement is installed in a walk way on the main campus near Kay Spiritual Center.
6. A cistern in Cassell is used to collect water for irrigation.
None
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? :
Yes
None
A brief description of the institution’s rainwater/stormwater management policy, plan, and/or strategies for ongoing campus operations:
The university uses a variety of strategies to deal with rainwater on campus. The university has rain gardens, cisterns, and bioretention ponds in place to help manage rainwater. Additionally, the university attempts to reduce impermeable hardscape altogether and use pervious pavers when possible.
