Pavement Maintenance Program

The purpose of the City’s pavement maintenance program is to use a priority system for the effective and economical repair of deteriorated pavement and the preservation of good pavement. Several factors contribute to the prioritization of repairs, including safety, pavement condition, traffic volume, ongoing programs, and future projects.

In order to record pavement conditions objectively, the City uses the Lucity computer program to interpret the type, severity, and extent of the cracks, potholes, and other issues found with the pavement and to turn this information into a street’s pavement condition index (PCI). The PCI is a numerical rating on a scale of 0 to 100, where 0 represents a failed street and 100 represents a perfect street.

Pavement conditions are useful only if they are current. Therefore, City staff typically review at least one fourth of the City’s streets each year.

FY2021 Pavement Program projections

The City typically uses five major programs to improve, repair, and maintain its pavement network. Staff reviews the pavement conditions each winter and spring and makes recommendations of which streets to include into the annual programs to the City Council as part of the Capital Improvement Plan process.  Each program is evaluated on an annual basis for that year's work and for the work that is expected in the next few years. 

Most of the City's annual pavement improvements are funded through a capital improvement sales tax.  The economic decline and lower sales tax revenues that resulted from the coronavirus have forced the City to significantly reduce its pavement program for FY2021.

The City's fiscal year begins on July 1 each year and ends on June 30 the following year.  For example, FY2021 is the period between July 1, 2020, through June 30, 2021.

Asphalt Pavement Resurfacing

This project involves removing and replacing the top few inches of asphalt pavement and is generally performed on asphalt streets with significant deterioration.  The FY2021 resurfacing program will not involve repaving entire streets; rather, it will focus on partial-depth asphalt pavement repairs for streets like Craig Road, Ladue Meadows, and Mosley Road.

Concrete Pavement Replacement

The concrete pavement replacement project involves the removal and replacement of failed concrete pavement and curbing. Streets are included in this program to address a specific hazardous section, to support other pavement programs, or to make an overall improvement to a deteriorated street.


Microsurfacing is a surface seal that helps preserve asphalt pavement that is in good condition and that can be used to delay asphalt resurfacing. The City’s Public Works crews typically begin pavement repairs on streets in this program up to a year in advance of the microsurfacing. This project typically concentrates on neighborhoods rather than individual streets.


Roadway reconstruction is reserved for streets that have reached the end of their useful lives and can no longer be maintained.  This program has been postponed for FY2021 and will be re-evaluated in the spring of 2021.

Sidewalk Improvements

The City dedicates approximately 10% of its annual pavement maintenance budget for sidewalk improvements, with the goal of bringing its entire sidewalk network into compliance with current accessibility standards. Curb ramps, broken sidewalk, and tripping hazards are included in this program, which often coincides with or precedes roadway improvements on the same street.  Sidewalk improvements in FY2021 will be focused on the sidewalk along Cross Creek Drive.

Grant Projects

Federal grants have greatly assisted the City in maintaining its major roadways and sidewalks. Past grants have partially funded projects to improve New Ballas Road (2008), Spoede Road (2010), Conway Road (2012), Ladue Road sidewalk (2013), Graeser Road (2015), Coeur de Ville (2016), Emerson Road Sidewalk (2017), Warson Road (2018), and North New Ballas Sidewalk (2019). Upcoming grant-funded projects include:


This project replaced the asphalt surface of Fernview Drive from Olive Boulevard to Gallagher Road.  Construction of this project is nearly complete.

Emerson Road Improvements

Improvements to Emerson Road will include minor roadway widening, adding a curb to both sides of the street, and roadway resurfacing to improve the safety of this street.  These improvements will complement the sidewalk that was constructed in 2017 and will complete the work envisioned by the Emerson Road concept plan that was completed in 2011.  The City is currently seeking bids for this project, and construction is scheduled to begin in early 2021.


Improvements to Mosley Road will include minor modifications to several of the curves and hills of Mosley Road to improve safety, sidewalk updates, and asphalt pavement resurfacing.  The project will involve all of Mosley Road, from Olive Boulevard to Ladue Road, and a federal grant will assist with the cost of the section between Olive Boulevard and Tureen Drive.  The improvements to Mosley Road will follow the preliminary plans that were developed for the project in 2014.  Design of the project is underway, and the City is beginning to review the various easements needed to complete the project.  Construction is planned to begin in the spring of 2022. 


This project will involve concrete pavement and sidewalk repairs to the section of North New Ballas Road between Olive Boulevard and Craig Road.  The design for this project is expected to begin in late summer 2020 with construction in 2023 or 2024.
