Project Overview
A portion of the Meramec Greenway in Unger Park has been closed as a result of repeated flooding. We are working with St. Louis County to rebuild the greenway in a location that is resilient to flooding conditions and make other enhancements within the park. When complete, the greenway in Unger Park will be connected to Fenton City Park, George Winter Park, and the walking/biking bridge over the Meramec River along I-44.
Project Location
Unger County Park in St. Louis County near Fenton, Missouri.

Community Feedback: Shaping the Greenway
Between November 2022 and September 2023, we convened a Stakeholder Advisory Group, conducted a public survey, and attended community events and pop-ups to understand what you wanted to be able to see and do at Unger Park.
The new greenway improvements will:
- Be rebuilt in a location to reduce future flood damage.
- Provide connections to Fenton City Park, George Winter Park, and the walking/biking bridge over the Meramec River along I-44.
- Include scenic overlooks for viewing the Meramec River and plan for a future nature trail on the north and east sides of the lake.
- Complement the existing disc golf course and provide access to the lake edge for recreation.
- Prioritize park visitor and greenway user safety through design with a higher visibility trailhead and parking built in a more central location within the park.
