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

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

New constructions and major renovations are implementing diverse stormwater management techniques. For example, all materials are being contained in bins to avoid the contamination of groundwater when it rains and at the new Richard Ivey Building, there are two sinks for water collection. The water runs into these ponds and from there they flow to the stormwater drainage. Furthermore, Western regulates the flow of water going into the sinks by slowly releasing it, to avoid overflowing the capacity of the drainage pipe.


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

A brief description of the institution’s rainwater/stormwater management policy, plan, and/or strategies for ongoing campus operations:

Strategies for rainwater runoff management have been implemented at the new Richard Ivey School of Business. The Richard Ivey School of Business features a rain water collection system that will allow for rainwater to be used to irrigate the landscape and flush toilets/urinals.

The CMLP’s green roof is covered with flats of drought-resistant sedum, a hardy garden plant. The soil and plants insulate the building for sound, along with increasing the heating and cooling efficiency.

The new Richard Ivey building, the Althouse Green, and Springette buildings have stormwater retention ponds.
