Wilson Park Creek Reach 3 Project Update & Perennial Plant Swap
Saturday, October 8 from 10:00 AM - Noon
6th & Norwich (3989 S. 6th Street, Milwaukee)
Rain Location: Water Tower, 3rd Floor Conference Room (4001 South 6th Street, Milwaukee)
Join us to hear updates about the revitalization of Wilson Park Creek, see construction photos, and enter to win rain barrels and native plants. The Garden District is hosting their perennial plant swap at the same time so bring your plants to swap or plan to pick some up if you are in need of more.
The construction work for the Wilson Park Creek – Reach 3 project is underway! The notice to proceed for Phase 1A construction on the basin, was provided to Michels Construction, Inc. in April 2022. This construction contract includes excavation of most of the flood storage basin behind Alro Steel (west of South 6th Street and south of I-43), along with a driveway entrance to the site, a temporary outlet pipe from the basin to the creek, and vegetation restoration of the site.
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 soil has found a new home! The anticipated truck haul route will be on South 6th Street and West Layton Avenue.

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.
A printable overview for the Wilson Park Creek Reach 3 project can be found here.
The Wilson Park Creek project will help to address issues related to floodwater management by:
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.
