The main runway at Paine Field is scheduled to close for seven days in August to allow for repairs after recent maintenance by an outside contractor failed to produce expected results.
The closure now is planned from 7 p.m. Aug. 23 through 7 p.m. Aug. 30, depending on weather.
Crews plan to create a new runway surface by milling down and overlaying a strip running up much of the 9,010-foot runway’s centerline. The newly paved area would be 65 feet wide and about 8,000 feet long under the latest plans. Work also will focus on sealing seams and repainting markings. The work should insure the runway is ready to support commercial air service and the airport’s aerospace businesses.
The project is necessary because an oil-based fog seal treatment applied to the runway in July is not performing as expected. Since then, there has been an unusual amount of loose material on the runway and surface friction numbers intermittently have fallen below acceptable levels.
The repaving project is expected to cost approximately $5.5 million and the Federal Aviation Administration has offered nearly $1 million in assistance to date.
Paine Field Airport is owned and operated by Snohomish County. The County Council authorized spending on the project Monday, July 30.
