MSD Project Clear will increase the size of the sewer system in these neighborhoods which will reduce basement backups and prevent sewer overflows in this area.
Why is this project being constructed?
MSD has invested over $2.6 million into this neighborhood to design and construct this project to increase the capacity of the sewer system and minimize the instances that the system becomes overcharged and backs up in to either residential basements or out into our local waterways.
How will it be built?
The majority of the project will occur behind the houses in the Wedgewood neighborhood off New Halls Ferry Rd in Florissant, almost entirely alongside the improved channel located within the neighborhood.
The project will be built by digging through the surface of the ground to a depth between 10 and 25 feet, in a process known as “open-cut” construction. Crews will excavate the ground first and then lay almost 6,000 feet of new, bigger wastewater sewer. Typically, crews are able to construct 50 to 100 feet of pipe every day, depending on weather and various other factors.
How will this affect residents?
As with any major construction project, residents in this neighborhood can expect to see and hear heavy construction equipment.
Roads where open-cut construction will be used may be reduced to a single lane. Trenches installed in streets will be backfilled with rock. Normally trench backfill occurs soon after the pipe is installed so the traffic lane will be drivable shortly after the sewer is installed. Except for very narrow streets, one lane of traffic will be open except when the contractor is loading the excavated soil into trucks.
The contractor will follow all local ordinances and will notify all properties of any temporary access restrictions. In areas where open-cut construction will be used, there will be periods when driveways may be inaccessible. The contractor will give all property owners ample notification prior to any access restrictions.
When will construction take place?
This is the current tentative project schedule. This is subject to change based on a variety of factors including weather.
- Project design completion date: September 14, 2018
- Easement acquisition completion: October 7, 2019
- Construction start: September 2020
- Construction completion: October 2021
- Estimated restoration completion: February 2022 (weather depending)
What will it look like when it's done?
The streets in this area have a concrete base with asphalt on top. Our contract specifies that the concrete slabs that are disturbed will be fully replaced for full slabs joint to joint and asphalt overlaid. The project’s restoration will meet all requirements of the City of Florissant.
Areas of restoration of yards disturbed by construction not located in existing easements have already been negotiated with property owners. The Contractor will work diligently to restore disturbed surfaces to previous or better conditions. If you have questions about timing of restoration, please contact the Project Manager.
Residents should not have any access issues to their properties. Most of the work on this project will be taking place in backyards.
Restoration will depend on when sod will be available and weather conditions during the winter. The Contractor will be working diligently to complete restoration in a timely manner.
There may be momentary outages for individual houses while that house is being transferred to a temporary relocate. This will only happen where there is a conflict with construction equipment and overhead lines. This could affect power, telephone, and cable, at different times. The interruption is expected to only be momentary.
Disruptions could still occur if utilities have not been marked correctly. In the event that the Contractor runs into unexpected utilities and service is disrupted, they will work to restore service as quickly as they can.
Yes, it is possible to hook up to MSD’s system from a private septic system. If you are a homeowner with a septic system, please reach out to the Project Manager to let them know so that as the Contractor works through the neighborhood, they can add your property to MSD’s main.
As of this point, most of the clearing and removal will be done at the same time.
