include downspout disconnection, foundation drain disconnection, lateral repair, lateral rehabilitation 
and improved surface water drainage. 

The 30th Street Greenway Corridor project, one of MMSD’s major flood management projects, will 
mitigate surface flooding, reduce basement backups plaguing the area and improve water quality as well 
as contribute to a broader economic and community development initiative to revitalize the area. 
MMSD formed the Corridor Advisory Council comprised of a number of partners whose work is engaged 
in or is influential to the Corridor; engagement and input of these stakeholders are central to the 
success of this project. The plan calls for building three flood basins that will be dry until needed, will 
capture and store 40 million gallons of stormwater, reduce the risk of flooding, and incorporates 
aesthetic, recreational and safety concepts that neighbors desired, including usable green space.  

GI will be a critical component to help meet the goal of eliminating all sewer overflows as stated in the 
2035 Vision and Strategic Objectives.  To further evaluate the potential of green infrastructure to help 
eliminate overflows, MMSD conducted a study in 2011 to assess the ability of a variety of practices to 
detain, evapotranspire, and infiltrate stormwater within the combined sewer service area (CSSA). The 
report,  

Determining the Potential of Green Infrastructure to Reduce Overflows in Milwaukee, can be found at

In 2012, MMSD contracted with the University of Wisconsin-Milwaukee Center for Economic 
Development to analyze the financial impacts of MMSD’s green infrastructure (GI) strategies on 
property values for four selected study areas within the MMSD service area. The report, Impact of 
Green Infrastructure on Property Values within the Milwaukee Metropolitan Sewerage District Planning 
Area: Case Studies can be found at www.freshcoast740.com.  

MMSD is a founding member of the National Science Foundation Industry/University Collaborative 
Research Center on water technology established in Milwaukee. The goal of the center -- one of about 
55 NSF centers in the country and one of only two that focus on freshwater issues -- is to spur local 
economic growth by combining the engineering research expertise at UWM and Marquette with 
industry needs involving water equipment, policy and technology. 

MMSD established a recognition program, Green Luminaries, to acknowledge businesses and 
organizations that have received partial funding for green infrastructure installations. The program 
highlights leaders, businesses, organizations, projects and programs that are advancing the use of green 
infrastructure and having a positive impact on water quality in the region. The Green Luminary, chosen 
monthly, is featured in a short video posted to MMSD’s website and social media.  

To encourage the installation of rain gardens on private properties, MMSD hosts an annual rain garden 
plant sale that provides plants at about a 50% discount compared to comparable retail plants and offers 
a free rain garden design workshop in partnership with UWEX Master Gardeners. Over 34,000 plants 
have been sold through this program. 

In 2005, MMSD began a rain barrel program providing rain barrels at a reduced cost to District residents 
through a network of outlets and through MMSD’s neighborhood GI programs. Over 23,000 rain barrels 
have been distributed to date.
