We are in the final stages of design! Scroll through the images below to see what’s ahead for the park, including a more natural Kinnickinnic River, expanded green space, and improved recreation areas designed to reduce the risk of flooding, restore habitat, and enhance the park.
Click the links under each image to hear directly from local community members about these changes and what they mean for the neighborhood.
To make space for future restoration of the Kinnickinnic River north of the Parkway, new sports courts and soccer fields were constructed last year. The courts are now open, and the soccer fields will open in fall 2026 once the grass is fully established.
Bird’s-eye view of proposed improvements in Jackson Park (north end looking south). The project will bring the river to the surface, reshape and lower the land to give the river more room during heavy rains. The project also dredges the lagoon, reconstructs the Kinnickinnic River Parkway, relocates the bike trail off the parkway, adds a new playground and other enhancements.
Hear from Patrick Elliott, MMSD Project Manager, about these changes.
View of the open-air pavilion with steps leading down to the water. Including ADA walkways, and in the distance, a fishing pier.
Hear from Mike and J from Friends of Jackson and Manitoba Parks about why they’re excited about these improvements.
The open-air pavilion with picnic or event space and restrooms. The plaza offers clear views of the revitalized lagoon, with upgrades around the pavilion to better support the farmers’ market and community events.
Hear from Dena and Marsha with the Jackson Park Farmer’s Market about how these changes will support the market and other community events.
Basketball courts will be relocated to the northwest corner of the park along S. 43rd Street, with an updated parking lot just south and views of the renaturalized Kinnickinnic River.
Hear from Jen with the Jackson Park Community Association as she shares more about these changes and why they’re important for the community.
The project will daylight the Kinnickinnic River, currently underground beneath the soccer fields, and restore it to a natural stream. The project will also construct trails along the river to provide opportunities for the community to connect with the restored stream. The new playground is also visible in the background. Native plants along the river will support the health of the stream and habitat along the restored waterway, and the gently sloping park space will give the river room to spread during heavy rains.
Hear from Cheryl Nenn with Milwaukee Riverkeeper as she explains why this change is important for the environment and community.
The improved trail around the lagoon will have new overlook areas to pause and enjoy the scenery. The lagoon will be dredged, and its water level lowered about 6 feet, allowing it to hold more water during heavy rains. The larger island will remain but the smaller island will be reconstructed at the new water surface elevation. Native plants along the edges will improve water quality and provide a stable shoreline.
Hear from Holly, a community member, about how these updates enhance the park.
The Kinnickinnic River Parkway will include safer crosswalks, new curb bump-outs, and improved parking. The Oak Leaf Trail will be relocated off the parkway, creating a safer and more enjoyable experience for walkers and bikers.
Hear from Sergio with the Jackson Park Community Association and Oak Leaf Familia, and Cassie, a local community member , about how these improvements make the park safer.
The new playground includes swings, a tower with slides, climbing structures, seating for adults, river views, and features accessible for people of different abilities.
See how Jordann Conley, a Manitoba Elementary School teacher, plans to utilize the new playground, and how her students helped shape its design.
An improved pedestrian bridge will connect the walking trail around the lagoon. During heavy rains, water from the river will flow under the bridge and fill up the lagoon. When the storm passes and the water level on the river recedes, the water in the lagoon will flow back under the bridge into the river, returning the lagoon to normal levels. The bridge, similar to the pedestrian bridge in Pulaski Park, will span 150 feet, and in the distance, you can see a new fishing pier.
Hear from Patrick with Milwaukee County Parks about these changes.

Explore Jackson Park at your own pace and see where changes are taking shape. Follow the self-guided tour to learn how the park and river will transform, with stops highlighting key project features.
We are continuing to move through the final stages of design, including coordination, permitting, and other project preparations. Construction is currently anticipated to begin in 2027, with plans to advertise for construction bids in early 2027.
When construction begins, the Kinnickinnic River and Jackson Park project area within Jackson Park will be closed for multiple years while the work is underway. While this will be a significant disruption, it will allow us to complete long-term improvements that reduce the risk of flooding, restore the Kinnickinnic River, and create a healthier, more welcoming park for the community.
The Milwaukee Metropolitan Sewerage District (MMSD) is partnering with Milwaukee County Parks and others to make improvements along the Kinnickinnic River and within Jackson Park. Jackson Park is a regional park on Milwaukee’s south side, located on the Kinnickinnic River Parkway. The lagoon, natural wooded areas, picnic sites, playfields, summer farmers’ market, and other recreation amenities make this park a popular destination for the neighboring communities. The Kinnickinnic River flows through the park but you might not even realize it! Currently, a significant portion of the river in Jackson is lined in concrete channels or enclosed in culverts.
The Kinnickinnic River at Jackson Park project is part of the larger Kinnickinnic River Watershed Flood Management Plan. The goals of this plan include:
To allow for more storage of floodwaters during heavy storms and to naturalize the river, more than 2,100 feet of concrete channel lining and enclosed culverts will be removed and replaced with a natural stream design. Because of this, elements of Jackson Park will have the opportunity to be re-envisioned to better support recreation and the community! Some of these changes will include increasing the size of the park, removing contaminated sediments from the lagoon, improving trails, and updating sports courts.
Based on feedback from the public, MMSD and Milwaukee County entered into an agreement in May 2020 to design and construct the Kinnickinnic River & Jackson Park project. MMSD and County have been working to refine the draft initial project design and will continue to seek public input throughout the design process.
To reduce the flood storage needed in Jackson Park MMSD is partnering with the City Of Milwaukee to create a flood storage basin north of the park. During a heavy rain, water will flow into the basin from the 43rd Street Ditch, where it will be held, until it begins to slowly move into the Kinnickinnic River in Jackson Park. Learn more about the 43rd Street Ditch project.

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.
The Milwaukee Metropolitan Sewerage District is partnering with Milwaukee County Parks and others to remove the concrete lining and restore the Kinnickinnic River to a natural stream in Pulaski Park. The project will reduce neighborhood flooding and improve public safety by slowing down the river in the park.
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
