The City has recently began a comprehensive, objective analysis of street conditions throughout the community. This effort resulted in the Pavement Condition Index (PCI) study which yielded a list of streets that should be worked on first based on conditions and priorities. This study was the first step to developing a Pavement Management Program for the City. The PCI is a numeric score related to the condition of the street; the amount and severity of distresses are factored into this score. Streets that are in better condition have a higher score than others.
Pavement Management Programs are designed to make modest repair and restoration investments in streets to achieve a high PCI score. The City is able to save money over time by making this modest investment in the street while it is still in a reasonable condition versus waiting until the street fully fails and requires full reconstruction. The PCI is used to identify the optimum point to make this modest investment in the street(s). City Staff has since used the results of the PCI study to develop a construction plan to address the project list while staying within the previously approved budget amounts.
A three-person team has further reviewed the streets’ conditions and refined the necessary scope of work needed for each street on the project list. As the City embarked on other construction projects, such as the Schertz Parkway reconstruction, the cost estimates were also refined based on the recent bid pricing. Staff has developed a construction plan that completes the necessary improvements to all of the streets identified in the original project list (except for a segment of Wiederstein Road), in addition to other streets that were approved in the budget. The segment of Wiederstein Road was removed from the initial effort because there is development interest along this same segment of roadway. Developers are often required to make certain improvements to roadways, so it is prudent to delay working on this segment of Wiederstein Road until after the developers complete improvements.
This plan was presented to City Council during the November 28th meeting. Council concurred with staff’s recommendation and is now working diligently to arrange for the needed geotechnical investigations and plan preparations for a construction project.
Stay tuned for more information on this effort as the City gets closer to the start of construction. Staff will continue to review street conditions and update the PCI values as time goes on. They will also be identifying the next round of streets ready for repairs/restoration. As these future lists are developed, they will be presented to Council.
