Executive Summary:
The Department of Public Infrastructure (SPI), Airport Division (Airport) is requesting the approval of the plans and specifications for the Charles M. Schulz - Sonoma County Airport Runway 14-32 repair project, award of a construction contract to the lowest responsive and responsible bidder, and authorization for the Director of SPI to execute the construction contract. As part of this project, Airport staff is recommending a 15% construction contingency to account for any unforeseen circumstances that cannot be predetermined prior to the start of the project.
Discussion:
The Airport has been monitoring two areas of runway 14-32 for pavement deterioration and signs of culvert failure. During this time, the Federal Aviation Administration (FAA) has inspected the associated areas and recommended monitoring requirements for the pavement sections. In the Winter of 2023-24, the Airport and the FAA observed that the pavement in question had further deteriorated and determined that permanent repairs are required to ensure continued compliance with FAA safety and operating standards. To meet these standards, the Airport is proposing the following repairs:
1. Reconstruction of a 24-inch culvert that crosses under runway 14-32 near the intersection of runway 2-20, and
2. Mill 4 inches of existing pavement and place new asphalt in an area of the runway where rainwater has been ponding.
The proposed work is scheduled to start early June and it will require closure of the airport’s two runways. The airport has coordinated with the FAA and stakeholders to mitigate the impacts of the expected 18 hours of work.
