Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:


Policies that dictate the Low Impact Development practices and best management strategies for stormwater control on construction sites for any state-controlled land include the Department of Administration/Division Facilities Development - Erosion Control master, Department of Administration/Division of Facilities Development - Civil and Sitework Guidelines, and State of Wisconsin Administrative Code, University of Wisconsin System, Chapter 18: Conduct on University Lands,

Design a sediment and erosion control plan, specific to the site that conforms to the requirements of NR 216 or COMM 61.115, NR 151 and any local construction site erosion control ordinances. The plan shall meet the following objectives:

Prevent loss of soil during construction by stormwater runoff and/or wind erosion, including protecting topsoil by stockpiling for reuse, prevent sedimentation of storm sewer or receiving streams, and prevent polluting the air with dust and particulate matter.

Stormwater is dictated through State of Wisconsin Statues NR 151: https://docs.legis.wisconsin.gov/code/admin_code/nr/100/151

SUSTAINABLE FACILITIES STANDARDS: https://doa.wi.gov/DFDM_Documents/MasterSpecs/Sustainability/Sustainable%20Facilities%20Standards.pdf

- Site Development: Protect or Restore Habitat
On greenfield sites: Limit all site disturbance to 40 feet beyond the building perimeter; 10 feet beyond surface walkways, patios, surface parking and utilities less than 12 inches in diameter; 15 feet beyond primary roadway curbs and main utility branch trenches; and 25 feet beyond constructed areas with permeable surfaces (such as pervious paving areas, stormwater detention facilities and playing fields) that require additional staging areas in order to limit compaction in the constructed area.

On previously developed or graded sites: Restore or protect a minimum of 50% of the site area (excluding the building footprint) with native or adapted vegetation. Native/adapted plants are plants indigenous to a locality or cultivars of native plants that are adapted to the local climate and are not considered invasive species or noxious weeds. Projects using vegetated roof surfaces may apply the vegetated roof surface to this calculation if the plants meet the definition of native/adapted.

- Reduced Site Disturbance: Development Footprint
Reduce the development footprint (defined as entire building footprint, access roads and parking) to exceed the local zoning’s open space requirement for the site by 25%. For areas with no local zoning requirements (e.g., some university campuses and military bases), designate open space area adjacent to the building that is equal to the development footprint. Maximize development using vertical rather than horizontal strategies.

- Permanent Stormwater Management: Discharge Rate and Volume, per DNR 151
If existing imperviousness is less than or equal to 50%, implement a stormwater management plan that prevents the post-development 1.5 year, 24 hour peak discharge rate from exceeding the pre-development 1.5 year, 24 hour peak discharge rate.
If existing imperviousness is greater than 50%, implement a stormwater management plan that results in a 25% decrease in the rate and quantity of stormwater runoff.

- Permanent Stormwater Management: Quality Treatment, per DNR 151
Construct site stormwater treatment systems designed to remove 80% of the average annual post-development total suspended solids (TSS) and 40% of the average annual post-development total phosphorous (TP) based on the average annual loadings from all storms less than or equal to the 2-year/24-hour storm. Do so by implementing Best Management Practices (BMPs) outlined in Chapter 4, Part 2 (Urban Runoff), of the United States Environmental Protection Agency’s (EPA’s) Guidance Specifying Management Measures for Sources of Nonpoint Pollution in Coastal Waters, January 1993 (Document No. EPA-840-B-92-002) or the local government’s BMP document (whichever is more stringent).

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:


As of September 17, 2007, the Wisconsin Department of Natural Resources determined that discharges from the campus Municipal Separate Storm Sewer System (MS4) will be authorized and regulated under Wisconsin Pollutant Discharge Elimination System (WPDES) MS4 General Permit No. Wl-S050075-1 , Municipal Separate Storm Sewer System, in accordance with ch.283, Wis. Stats., and subch. of ch. NR 216, Wis. Adm. Code. Accordingly, the University of Wisconsin - Whitewater must comply with the terms and conditions of the permit in order to lawfully discharge storm water from its MS4 to waters of the state.


Associated with the MS4 Permit, the campus partnered with the City of Whitewater as well as other municipalities in the Rock River basin in forming the Rock River Stormwater Group in December 2008 for the purpose of coordinating efforts in public education and public outreach on storm water issues.

The University of Wisconsin-Whitewater Storm Water Management Plan was completed in August 2006, by Norris and Associates, Inc of Milwaukee, WI. This plan serves as the guide for the university in compliance with stormwater regulations. Additionally, a Stormwater Quality Management Plan was also completed for the university by Strand Associates of Madison WI on December 3, 2008, in conjunction with a Stormwater Quality Management Plan that Strand completed for the City of Whitewater. This storm water management plan is being maintained and updated as required to reflect significant progress and/or change in regulations, and it is being used as a guide in managing storm water issues, new construction, etc. on campus.
