Pavement Maintenance Program

The purpose of the City’s pavement maintenance program is to use the City's resources and opportunities to provide the best streets and sidewalks possible.  To this end, the City's Department of Public Works plans the annual pavement maintenance programs using 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.

Department of Public Works staff use the Lucity/Central Square computer program to objectively 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.  The average PCI for a City street is currently 75, which is considered "very good."

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.  An independent review and update for all of the City's streets will be completed in late 2021.

FY2022 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. 

The City's fiscal year begins on July 1 each year and ends on June 30 the following year.  For example, FY2022 is the period between July 1, 2021, through June 30, 2022.

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 surface deterioration.  The FY2022 resurfacing program will repave several streets in poor condition.  This projects will finish work in the Fairways subdivision that began in 2019 and will begin multi-year resurfacing programs in the Ladue Heights subdivision and in the Creve Coeur Executive Office Park.  Map of FY2022 asphalt resurfacing project and future projections.

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.  Map of FY2022 concrete project and future projections.

Microsurfacing


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.  The focus in FY2022 is to complete subdivisions along the Mosley corridor in order to minimize construction in this area during the Mosley Road improvement project.  Map of FY2022 microsurfacing project and future projections.

Reconstruction


Roadway reconstruction is reserved for streets that have reached the end of their useful lives and can no longer be maintained.  The FY2022 project has been incorporated into the grant-funded Mosley Road project in order to extend this project south to Ladue Road.  Map of FY2022 reconstruction project and future projections.

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 FY2022 will be made throughout the City with the most significant work being the replacement of the sidewalks along Studt Avenue and Olde Cabin Road.  Map of FY2022 sidewalk improvements and future projections.

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), Fernview Drive (2020), and Emerson Road (2021). Upcoming grant-funded projects include:

Mosley Road IMPROVEMENTS


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 and easement acquisition for the project are now complete.  Construction is planned to begin in early 2022 and last into early summer 2022.


NORTH NEW BALLAS IMPROVEMENTS


This project will include two areas of improvements.  The largest portion of the project will involve concrete pavement and sidewalk repairs to the section of North New Ballas Road between Olive Boulevard and Craig Road.  The second portion will focus on sidewalk improvements and will add a sidewalk between the U. S. Post Office and Rocky Drive.  The design for this project is underway.  Construction is planned for the spring of either 2023 or 2024.
 

NEW SIGNAL AT LINDBERGH AND OLD OLIVE


The City plans to add a traffic signal at the intersection of Lindbergh Boulevard at Old Olive Street Road.  This signal will reconnect the two sections of Old Olive Street Road for both motorists and pedestrians, and it is considered a critical step toward realizing the vision laid out for the area in the 39 North Master Plan and the Old Olive Great Streets Plan.  Design for this project is currently underway.  Construction is planned for the spring of 2023 or the spring of 2024.

Craig road improvements


The City maintains the portion of Craig Road south of Olive Boulevard.  Improvements to Craig Road will include new and expanded sidewalks, modifications to the intersections at Olde Cabin Road and at Office Parkway to make these intersections more intuitive for drivers and pedestrians, and a new asphalt surface.  The design for this project is planned to begin in 2022, and construction is tentatively scheduled for the spring of 2025.
