Annual Slab Replacement Project

The Slab Replacement Program is part of the City’s ongoing effort to maintain and improve the roadways. It focuses on replacing individual concrete slabs in deteriorated areas rather than repaving entire streets.

The City’s Engineering Department evaluates slabs using criteria such as visible damage, cracking, settling and overall condition. Based on the severity of deterioration and available funding, a priority list is created.

Streets are prioritized based on inspections, condition assessments, and budget allocations. If your street isn’t included this year, it may be scheduled for future work.

You can submit a request through our Concern Center at www.wentzvillemo.gov/ConcernCenter or contact the City’s Engineering Department directly. All requests are reviewed and added to the evaluation list for future planning.

Due to the nature of the program, specific timelines for individual streets are determined by the contractor’s schedule, weather conditions and project progress. Affected residents will be notified in advance of any work on their street.

Access may be temporarily restricted while the concrete cures. Residents will be notified ahead of time to plan alternative parking arrangements. The contractors are obligated to restore driveway access within 10 days, however, they are typically re-opened much faster. 

You may park on adjacent streets during the project. No parking permits are required, but please ensure you follow standard parking regulations. The City also suggests talking with your neighbors to coordinate parking arrangements and minimize inconvenience during the project.

The replacement of an individual slab typically takes less than 10 days. This includes breaking, excavation, re-pouring and concrete cure time. The length of time varies depending on weather and cure time, for example.  

Delays may occur due to weather, unforeseen site conditions, traffic volumes, and/or contractor schedules. The City and contractors work to minimize delays and complete the work efficiently.

The City contracts with licensed and experienced companies to complete the slab replacement projects. City staff oversee the work to ensure quality and compliance.

The program is funded through the City’s budget, which is allocated annually for infrastructure improvements. In response to resident input, the City’s elected officials have continued to focus their attention on the annual street maintenance program. The budget for the Slab Replacement Program has increased year over year..

Replacing individual slabs is a cost-effective way to maintain roads in good condition without the higher costs associated with full street repaving.

Every attempt is made to reduce the risk of utility strikes. Even so, it is not possible to avoid every single one. Locates may not be accurate, may not show the utility at all, or the utility may be laid such that it is impossible to avoid. If the contractors hit a utility line, they immediately call the service provider to schedule repairs. The utility provider schedules a time in which they can send out repair crews. Repair details will be communicated directly to the resident through the utility provider.

You can submit a concern at https://www.cognitoforms.com/CityOfWentzville/SlabReplacementProgramConcern. Pre-construction photos are taken to compare pre- and post-construction. Property damaged prior to the start of construction will not be repaired. The contractors are obligated to repair and restore private property damaged due to construction. They may replace mailboxes with a like-type, backfill and seed/straw yards, or patch new damage to driveways. You do not need to submit a concern for backfilling behind the curb, around driveways, and/or sidewalk ramps. That will be done automatically as a part of the contract at the appropriate stage of construction. 

If you have a need for constant driveway access, contact the city Project Manager to help ensure there is as little impact as possible to accommodate your daily needs. 

If a slab replacement project impacts you, the City distributes multiple communication pieces to those who will be affected. These may include a mailer, a door hanger, and a yard stake or sign. 

The City provides general slab replacement information in many places, including our website, eNewsletters, postcards delivered to impacted areas, yard stakes, neighborhood entrance signs, the CityScape publication, The Vision newsletter, and additional channels as needed.

Every attempt is made to keep traffic flowing as close to normal as possible. However, on two-way streets, there may be periodic delays of up to 10 minutes. That is how long it typically takes to empty out a full concrete truck. Finding alternate routes and/or planning for delays is the best way to ensure you get to where you need to be in a timely manner.
