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:

We have developed natural runoff management systems for new development on campus. The new Warch Campus Center, for example, has a layered stormwater runoff pond that discharges into the Fox River as well as a "green roof" of hardy, drought-resistant plants.


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:

We are required to follow city guidelines for all storm water


A brief description of any rainwater harvesting employed by the institution:
---

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

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:

The Warch Campus Center has a large section of "green roof". As a student explained on the Green Roots blog, "This is a series of rectangular containers that are set up in rows (and spaced for easy maintenance) and house pre-planted, fully matured plants that are drought and winter resistant. This includes Gold Leaved Goldmoss Sedum, White Flowered Sedum, Kamtschatica Sedum, Neon Sedum, Tricolor Sedum, Voo Doo Sedum, and Vera Jameson Sedum. The containers are placed on top of the TPO membrane mentioned above, and can easily be removed if needed. The plants use the sun’s energy to survive and grow and help keep the roof cool via evapotranspiration. The eight inches of soil they are planted in also acts as an insulator soil keeping the roof it cooler in summers, and a little warmer in winters. The plants also use rainwater for their survival, which cuts back and unwanted runoff, puddling, and rooftop water management."


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:

The campus garden collects rain water to use in part of their irrigation system.


A brief description of any stormwater retention and/or detention ponds employed by the institution:

There are three detention ponds used by the university to store water.


A brief description of any bioswales on campus (vegetated, compost or stone):
---

A brief description of any other rainwater management technologies or strategies employed by the institution:

The weather is always being observed so that water is never wasted by watering plants twice. Plants only receive watering when they need it, so watering is not too excessive.
