The goal of the Wilson Park Creek Reach 3 project is to reduce flood risk and is one part of MMSD’s larger Kinnickinnic River Watershed Flood Management Plan. The project will also increase public safety, improve riparian (area adjacent to the river) and aquatic habitat, and enhance stream channel aesthetics. The Wilson Park Creek project consists of three sections referred to as a “Reach”. The first section where design work has begun is in Reach 3 where we are designing and constructing a flood storage basin, reconstructing a non-concrete lined stream channel, and improving culvert capacity at South 5th and South 6th Street.
Wilson Park Creek Reach 3 is located between West Layton Avenue & South 1st Street and the Canadian Pacific Railroad (CPRR) tracks near I-94/43, on the southside in the City of Milwaukee. Approximately 3.7 square miles of highly urbanized land, including the majority of General Mitchell International Airport, drains into this section of Wilson Park Creek.
Approximately half of its 4,750-feet of channel is concrete-lined and in poor condition. High velocity water flows are present during storm events and approximately 60 structures within Wilson Park Creek Reach 3 Project are in the updated one-percent annual probability of flooding every year floodplain, which is also referred to as the 100-year floodplain. By removing the concrete and naturalizing and widening this channel, Wilson Park Creek is able to absorb more water at a safer speed and contributes to reducing the probability of structure flooding.

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:
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.
Stay tuned to this website and MMSD social media avenues (Twitter, Instagram, Facebook) for upcoming Wilson Park Creek outreach activities.
Kinnickinnic River Watershed Flood Management Plan
MMSD is partnered with the following entities on the Wilson Park Creek project:
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.
