Projects

As part of a long-term effort to reduce basement backups and sewer overflows, MSD Project Clear is constructing approximately 1,320 feet of creek bank stabilization and 154 feet of stormwater pipe in unincorporated St. Louis County.

About the Project

What is the goal of this project?

MSD Project Clear is investing approximately $2,000,000.00 to construct this project to prevent creek bank erosion by installing rock stabilization in unincorporated St. Louis County.

The creek in this area is experiencing erosion.  This project will stabilize the creek bank to improve water flow and protect some of the nearby private properties from creek erosion.

Project Facts

• Construction is estimated to begin as early as Fall 2024
• MSD Project Clear will stabilize approximately 1,320 feet of natural creek bank using rock lining.
• MSD Project Clear will repair and intercept overbank erosion and extend the existing storm sewers.
• The pipe size will be between 18 and 48-inches in diameter, allowing a larger amount of water to flow through the system.

What can residents expect?

This project will be constructed using “open-cut” construction. Open-cut construction is when MSD’s contractor will put the pipe in by digging through the surface of the ground in a process known as “open-cut” construction. The pictures above depict what a neighborhood will look like before, during and after a typical open-cut project. However, “open-cut” will only be used where stormwater pipe outfalls are being replaced.

With any type of construction, residents can expect to see and hear heavy equipment during the sewer excavation process.

Traffic and Access: Most of the construction will take place in the creek and along the creek bank, so any traffic disruptions will be limited to the construction access points on Halls Ferry Road.

Residents and/or property owners along the construction path should move the small portable items outside of the easements and inform MSD of dog fences, sprinklers, and other underground assets.

Restoration: After construction is complete, the contractor will restore the construction site according to all local and District requirements. This could include sodding any disturbed areas, replacing disturbed pavement, reinstalling fences, etc.

At least one MSD Inspector will be on-site part of the day every day the contractor is working.

What is the timeline?

This is the current tentative project schedule. This is subject to change based on a variety of factors, including weather.

• Estimated construction start: Fall 2024
• Estimated project duration: 12 months
