Pavement Maintenance Program

The purpose of the City’s pavement maintenance program is to establish 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.

IMS Review

The City hired Infrastructure Management Services (IMS) to use its vehicle-mounted equipment to measure the conditions of the City’s entire pavement network in early 2016. The independent assessment provided by IMS updated the City’s Lucity software, verified the accuracy of the condition ratings, and provided recommended pavement repairs based upon their findings.

Staff reviewed the final IMS report with the City Council at their meeting on July 25, 2016. The following documents are related to that review:

FY2017–FY2021 Pavement Programs

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. The programs for the FY2017–FY2021 construction season are briefly described below.

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 program concentrates on streets along Olive Boulevard that have been in need for some time.

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. The current reconstruction project is a continuation of work that was completed this spring.

Sidewalk Improvements

The City dedicates approximately 10% of its 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.

Grant Projects

Federal grants have greatly assisted the City in maintaining its major roadways. Past grants have partially funded projects to improve New Ballas Road (2008), Spoede Road (2010), Conway Road (2012), Graeser Road (2014), Coeur de Ville (2016) and Emerson Road (2016). Upcoming grant-funded projects include:

Warson Road Resurfacing

The City’s portion of Warson Road (from Olive Boulevard south to Countryshire Lane) will be resurfaced and its sidewalks will be improved. Construction will begin in the spring of 2018.

Emerson Roadway Improvements

The City has recently been awarded a grant for roadway improvements to Emerson Road. The design phase for this project will begin in 2017, and construction is projected for 2020.
