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:

UNL possesses a Small Municipal Separate Storm Sewer System National Pollutant Discharge Elimination System Permit issued by the Nebraska Department of Environmental Quality. The commitments made by UNL under the terms of this permit are designed to mitigate impacts of storm water runoff and include all construction sites and other land-disturbing activities, as well as other activities (e.g., fertilizer use, irrigation, deicing, livestock, illicit discharge detection and elimination, public education/outreach/involvement, housekeeping, etc.). The UNL SMS4 Storm-water Management Plan extends to the entire campus and all activities. New construction activities adhere to LEED principles and often incorporate storm water management strategies, such as reuse of storm water for irrigation, green roofs, retention ponds, porous paving, etc. UNL's Department of Environmental Health and Safety maintains a web page with Stormwater/Sustainability links in an effort to assist in educating the campus community (http://ehs.unl.edu/links) and maintains several Safe Operating Procedures relative to Storm-water Pollution Prevention

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:

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:

During a renovation to UNL's Whittier Building, Landscape Services installed a green roof to act as a test for the unconventional roof system. UNL will monitor the success of the program to determine its practicality for future projects.


A brief description of any porous (i.e. permeable) paving employed by the institution:

In its recent expansion of Memorial Stadium UNL installed the Silva Cell modular suspended pavement system along the 12th St. Mall. Silva Cells help hardscapes support large wight loads while only compacting soils lightly. Thus enabling tree roots the oxygen and water they need to support tree growth.

More information about Silva Cells can be found at: http://www.deeproot.com/products/silva-cell/overview

A brief description of any downspout disconnection employed by the institution:

Many of UNL's older buildings are disconnected from storm water drains. Splash guards push water out to landscape.

A brief description of any rain gardens on campus:

A Rain Exchange system was installed as part of the Keim Hall Courtyard renovation, capturing water from the roof drains for use in a teaching pond and as a source of irrigation.

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

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

A bioswale is being installed in new building for the Nebraska Center for Virology.

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

The 19th and Vine Parking Garage was constructed as a green parking garage. Water from the roof is captured into drains that lead to cisterns which in turn are used to water a portion of the landscape.
