Cedarhurst Drive Creek Bank Stabilization (11259)
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.

Project Map
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
FAQs
While MSD’s contractor is connecting a home’s lateral to the new wastewater sewer, they may ask residents to limit water use. In general, this process can take between two to five hours, depending on the complexity of the connection. The contractor will notify property owners in advance.
MSD does not anticipate other utility services being disrupted during this project. We will work with Missouri One Call to locate utilities before beginning construction. Occasionally, the contractor may run into utilities that were not located by Missouri One Call which could result in temporary utility disruptions. If this happens, MSD will work with the utility to restore service as quickly as possible.
Trees may need to be removed to construct parts of this project. If there are good options to avoid removing trees, MSD will make every attempt to do that. Property owners with trees that will need to be removed that are not located in already existing easements will have been compensated for the removal through the easement acquisition process.
In general, District policy is to restore affected areas to the same or better conditions than before the project. Streets that are disturbed through this project will be replaced and repaved with similar material. The project’s restoration will meet all local and District requirements.
During easement acquisition, an MSD Right of Way Agent will work with property owners to discuss restoration on their property. Most yard areas will be resodded with the same material. Driveways, walkways, and other hard surfaces will be restored using the same materials that are currently in place. In wooded ground areas, District policy is to seed the disturbed areas.
During active construction, some property owners may experience driveway access restrictions for a short period of time. The contractor will notify property owners in advance of any temporary access restrictions to allow them time to move their vehicles. The contractor will also fill trenches with gravel or place steel plates over trenches during non-working hours so residents can use their driveways during those times.
MSD will instruct its contractor to keep the site reasonably clean and clear of debris. MSD will have an inspector on site every day during active construction. Prior to the start of construction, MSD will give every resident and property owner along the construction site the inspector’s contact information. Community members are encouraged to bring any concerns to the on-site inspector or any other member of the project team.
