Thank you to all who participated in the survey for Phase 3 of the West Basin Project! Over the next few weeks, we’ll be assembling the feedback from the survey as well as from input from several focus group meetings, events, and door-to-door conversations in the neighborhood. We’ll circle back to you in early 2023 when the design is finalized. Check back to this page for news about the project and information about upcoming events at the West Basin. Thank you again!

The West Basin Stormwater Management Project is the third component of an integrated system of three dry stormwater basins to address recurrent flooding in the 30th Street Corridor. Flooding in 2008 and 2010 caused significant property damage in the neighborhood. The 30th Street Corridor Flood Management Plan was developed in response to these flood events. When completed, the 30th Street Corridor Flood Management Plan will significantly reduce flooding in the 30th Street Corridor from future major storm events.
The plan calls for the construction of three, integrated stormwater basins to hold rainwater from major storms. After the storms have passed, the water held in the basins will slowly drain to Lincoln Creek. The North and East Basins along North 30th Street were completed in 2018. The West Basin Stormwater Management Project is the final component to be constructed.
The West Basin has a planned capacity of 31 million gallons and is designed to reduce stormwater flooding up to a 100-year storm event. The City of Milwaukee is a major project partner and will have significant concurrent stormwater projects along N. 35th Street and W. Capitol Drive to further reduce flooding.
The project site is located along North 35th Street between West Congress and West Hopkins on ten acres of abandoned industrial property. The site is bordered on the east by a series of railroad tracks and on the west by a residential community. The property has a long history of industrial use and associated contamination. The removal of this legacy contamination is one of the first tasks that has been undertaken as part of this project.
The constructed basin will be roughly the size of ten football fields and nearly 20 feet deep, creating a significant change to the landscape and surrounding neighborhoods. Community engagement began two years in advance of the project to help residents understand the need for the basin and to prepare them to be involved in the stakeholder process.
North 35th Street is a high-traffic thoroughfare known for high speeds, accidents, and injury. It divides the neighborhood from the project site presenting significant concern to residents. Street safety will be one of the topics discussed in the engineering design process.
The project provides great opportunities for additional community amenities. The community has expressed interest in walking trails, a neighborhood gathering space, and modifications to improve the safety along 35th Street. These ideas will be considered as part of the engineering design stakeholder process. The Rails-to-Trails Conservancy has undertaken a study for the 30th Street Corridor Shared-Use Trail, a section would be located along the basin project site.
