EXECUTIVE SUMMARY
The Kingsdale Avenue (Grant Avenue to 182nd Street) Project, Job No. 40880 (Project), is designed to rehabilitate pavement on Kingsdale Avenue between Grant Avenue and 182nd Street using a full depth reconstruction method. It was initially thought that the rehabilitation of this project could be accomplished using the grind and overlay street improvement process. However, further geotechnical investigation revealed the absence of sufficient aggregate base layers under the existing pavement to use this less extensive approach.
This portion of Kingsdale is a primary corridor for bus and transit vehicles, serves several commercial businesses, and the South Bay Social District. Given the substandard pavement base structure and the use by heavier vehicles visiting the area, staff is recommending a full depth reconstruction for the entire length of the Project. Full depth pavement reconstruction involves completely removing and rebuilding the pavement structure, including the base layers, which provides a more durable long-term roadway.
The design of the Project is now complete and the construction plans and specifications have been finalized and are ready for competitive bidding upon approval by the City Council. The plans and specifications are available for review at the plans and specifications review area located behind the Engineering permit counter at City Hall and will be posted online by the first day of advertising. The Engineer's construction estimate for the project is $1.41 million and is within budget. Construction is expected to begin in June of 2025 and is estimated to take approximately 50 working days to complete.
