Milwaukee is situated on one of the largest fresh water bodies in the world - Lake Michigan and the rivers that feed into it. This amenity provides many opportunities for recreation and commerce. Protecting our lakes is critical for the city and for the region. Citizens, business, and government must take individual and community responsibility for keeping our lake and rivers clean.
Green Infrastructure Baseline Inventory
The ReFresh Milwaukee plan's Water Chapter establishes a goal to "Reduce stormwater runoff and clear water from entering sewer system". Targets toward achieving this goal include 1) establishing baseline measures of impervious surface and green infrastructure, 2) creating a City green infrastructure policy plan, and 3) increasing the volume of stormwater runoff captured through green infrastructure by 10% annually.
The Office of Environmental Sustainability, with financial support from the Fund for Lake Michigan, recently completed a Green Infrastructure Baseline Inventory to satisfy the first target above. This report documents existing green infrastructure with 14 million gallons of stormwater capture capacity in the City of Milwaukee. It also identifies impervious surfaces at 45.5% of city area and 163.4 miles of shorelines within city limits. The report serves as the foundation for the City's forthcoming Green Infrastructure Policy Plan.
The City of Milwaukee is exploring cost effective and innovative approaches for managing stormwater to help neighborhoods be more resilient to extreme storm events. One approach that is being studied is the BaseTernTM, an underground stormwater management or rainwater harvesting structure created from the former basement of an abandoned home that has been slated for demolition. By using this existing basement cavity, the City saves on demolition costs of the old structure and the construction of the new one. The structure would be underground and covered with turf to fit safely within the neighborhood. The preliminary prototypes can hold as much water as 600 hundred rain barrels!

The City of Milwaukee is designing city streets to reduce flooding risks, improve the quality of our lakes and rivers, and help the City adapt to a changing climate. Through guidance outlined in the City's Green Streets Stormwater Management Plan, as streets are scheduled to be repaired or replaced, the City is systematically evaluating opportunities to install new green infrastructure assets, such as bioretention basins in street medians and tree trenches near sidewalks. The Green Street Stormwater Management Plan was funded by the WI Coastal Management Program and the National Oceanic and Atmospheric Administration.
The City of Milwaukee's Green Infrastructure GIS Tool is publicly available. Through open data sharing, the goal is to facilitate the advancement of green infrastructure planning in the City of Milwaukee, and ultimately, make the City more sustainable and resilient.
Department of Public Works Stormwater Management Program
The City of Milwaukee's Department of Public Works Stormwater Management Program (SWMP) seeks to reduce the amount of polluted stormwater runoff that enters local waterways. The SWMP reviews and approves stormwater management plans submitted as required by Chapter 120 of the City of Milwaukee Code of Ordinances. The SWMP website contains valuable information about pollution prevention, management plans, erosion control, and the Stormwater Management Charge.
Reduce Your Stormwater Bill with Green Infrastructure
The City of Milwaukee finances stormwater management projects, including sewers, green infrastructure, and urban forestry through a Stormwater Management Charge. Commercial property owners can receive a credit on this quarterly charge by adding green infrastructure to their property. This worksheet provides additional information and allows you to apply for a credit.
NEW - Permanent Medication Collection Sites
The City of Milwaukee has instituted permanent collection sites for disposing of expired and unused medications. Complete information about the program can be found at the Health Department, and addresses for the drop-off locations can be found at Milwaukee Police Department.
