UPDATE: The ol’ campus is gone, and workers have been drilling 25 feet in the earth 2,300 times to install deep aggregate piers – made of compacted gravel – for the new Highline High School.

Demolition wrapped up at the beginning of November 2019, and now Skanska construction crews are doing rough grading to smooth or flatten the site prior to construction, installing underground utilities and placing footing framework, steel and concrete.

Workers have begun structural excavation on the north and east sides of the site.

Plans to place HHS tennis courts at the Sunnydale site have been submitted to the City of Burien for review along with plans for right-of-way improvements.

“Work is tracking ahead of schedule,” the district said. “We continue to expect the new school, designed by Bassetti Architects, to open September 2021.”
