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?:
A brief description of the institution’s Low Impact Development (LID) practices:
State and local government agencies mandate stormwater mitigation rules, which define required efforts for stormwater quantity detention and quality improvement with review and approval by the local jurisdiction. The most significant of these is the extensive use of bio-filtration cells for improvement of water quality and detention. These are required as permanent fixtures on essentially all new projects. Recent examples include:
The Station at Millpoint - four large bio-retention basins
Hunt Softball Facility - contains 16 bio-retention basins
South Campus - one large dry detention pond
Historic Neighborhood Parking Lot - underground storage devise which limits run-off rates and collects sediment
The university directs (whenever topographical elevations permit) all storm drainage water into three existing stormwater detention ponds, which are used as the primary irrigation source for the campus.
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:
The university directs (whenever topographical elevations permit) all storm drainage water into three existing stormwater detention ponds, which are used as the primary irrigation source for the campus. This system does not address all of the university's property.
A brief description of any rainwater harvesting employed by the institution:

Rainwater harvested directly and stored/used by the institution, performance year:
A brief description of any rainwater filtering systems employed by the institution to treat water prior to release:
A brief description of any living or vegetated roofs on campus:
There is a vegetative tray system roof, about 1,000 square feet in size, above the Winter Garden Cafe area of Lakeside Dining Hall. It is visible from an adjacent porch area and several windows. It absorbs rainwater, provides insulation, creates a habitat for wildlife and mitigates the heat island effect.
A brief description of any porous (i.e. permeable) paving employed by the institution:
A brief description of any downspout disconnection employed by the institution:
A brief description of any rain gardens on campus:
Bio-retention basins (also called rain gardens) are designed to take run-off directly from impervious surfaces into a basin filled with a high percolation rate growing media. This captures a significant amount of water and reduces storm surge in the streams allowing the water to escape over a longer period of time while the media and the plants therein act as a filter of sediments and pollutants thereby increasing water quality.
A brief description of any stormwater retention and/or detention ponds employed by the institution:
Retention ponds consist of three ponds located on campus which are fed by stormwater run-off. These ponds serve as settling basins for sediments and also serve to capture and decompose nutrients or pollutants through the in-pond aquatic vegetation. Each of these ponds is equipped with an irrigation pumping station so the water is further utilized on campus with the landscape acting as a filtration media.
A brief description of any bioswales on campus (vegetated, compost or stone):
Vegetative swales combine turf area and/or plantings to slow stormwater run-off, increase the amount which infiltrates into the soil and filter out suspended sediments or nutrients.
A brief description of any other rainwater management technologies or strategies employed by the institution:
