About the Program
The City of Elk Grove is responsible for the maintenance of approximately 1200 lane miles of roadway with over 89 million square feet of pavement. The goal of the Pavement Management Program is to maintain the city’s pavement in the best condition possible. Each year, preventive maintenance treatments are performed on various City streets. These treatment projects are intended to extend the life of the pavement and avoid more costly repair or replacement of streets.
Road reconstruction is considered when preventive maintenance treatments are no longer cost-effective or feasible. In this case, several more days are required in order to resurface the road and or replace the entire roadway structural section. Additionally, the cost of reconstruction can be greater than 10 times the cost of preventive maintenance.
The city uses StreetSaver®
, a Pavement Management Software, to monitor pavement conditions, help prioritize streets requiring resurfacing, and estimate costs of treatments and rehabilitation. StreetSaver®
uses Pavement Condition Index (PCI) to classify roads based on their condition. The PCI scale ranges from 0 to 100 (poor to excellent condition), depending on severity of pavement distress. PCI values are one of the many factors used by StreetSaver®
to help identify the appropriate resurfacing treatment for a given road.

Though funding amounts vary each year, the City’s approach is to allocate 75% of funds for preventive maintenance and 25% for reconstruction, whenever possible. This “Fix-it-First” approach of performing mostly preventive maintenance has been proven to extend the life of pavements and is less costly than reconstruction.
The City of Elk Grove is divided into 106 pavement management subzones. Preventive maintenance is typically performed to an entire subzone to maintain consistency of pavement conditions within neighborhoods and to limit the construction impact on residents. Reconstruction is performed where it is most needed and is too expensive to perform on a wide scale.
In order to maintain current PCI data, roads are inspected at varying intervals based on their type and traffic volume. Arterial and Collector streets are inspected every 2 years due to higher traffic volumes. Residential streets are inspected every 4 years.
