It's important that everyone take steps to reduce the spread of Coronavirus Disease 2019 (COVID-19). Find out more about COVID-19 in Milwaukee County, WI.
Following the public meeting in October 2019, we have been working to incorporate feedback received and continue to move the project forward. Over the last year, the team:
To build the flood storage basin, MMSD plans to remove about 200,000 cubic yards (about 15,000 dump trucks) of clean soil. Through a partnership with the City of Oak Creek, the dirt has found a new home! For more information please see this article.
Construction of the flood storage basin is on schedule for groundbreaking in late 2021! Scroll down on the page and subscribe to future email updates!
The Milwaukee Metropolitan Sewerage District is partnering with the City of Milwaukee and others to construct the Wilson Park Creek Reach 3 flood management project. The project is located between West Layton Avenue at South 1st Street and the Canadian Pacific Railroad (CPRR) tracks near I-94/43, on the southside of the City of Milwaukee. It drains approximately 3.7 square miles of highly urbanized land uses, including the majority of General Mitchell International Airport.
Approximately half of this section of Wilson Park Creek channel (4,750-feet) is concrete-lined and in poor condition. The creek fills quickly during rain events, and occasionally, these flood flows spill over the banks. New information now indicates that approximately 60 structures within the project area are at a high risk of flooding.
The Wilson Park Creek Reach 3 project is one part of a larger Kinnickinnic River Watershed Flood Management Plan, with the goal of reducing flood risk, improving public safety, improving riparian and aquatic habitat, and enhancing stream channel aesthetics. This is achieved by designing and constructing a flood storage basin, replacing the concrete lining and non-concrete lined stream channel with more natural stream design, and increasing the culvert capacity under South 5th and 6th Street.

Preliminary engineering was completed in July 2018 for the recommendations above within Wilson Park Creek Reach 3. The final design has been divided into two phases:
The project timeline is subject to change.
MMSD will conduct a number of stakeholder and public outreach activities throughout the entirety of the project to provide information, obtain project input and feedback.

MMSD is partnered with the following entities on the Wilson Park Creek project:
Kinnickinnic River Watershed Flood Management Plan
Wilson Park Creek Reach 3 – Phase 2 preliminary channel rendering looking west toward South 5th Street.
This section of channel will be widened to increase its flow capacity during extreme events and the turf grass will be replaced with trees, shrubs and prairie plantings.
The section of concrete channel will be replaced with a wider and naturized section.
This existing culvert will be replaced with a larger structure to increase its flow capacity during extreme events.

With extensive input from neighbors and nearby businesses, a project is underway to capture and store 40 million gallons of stormwater to reduce the risk of flooding when storms roll over the area
This project captures and stores potential floodwater in one large basin that covers about 65 acres and holds 315 million gallons of water.
Greenseams® helps prevent future flooding and water pollution while supporting and protecting MMSD's structural flood management projects - infrastructure investments worth hundreds of millions of dollars. Greenseams® is an innovative flood management program that permanently protects key lands containing water absorbing soils.
