Nathan Hale High School in North Seattle will reopen Monday morning after flood damage forced it to close for a week, said Principal Marni Campbell.

Rainwater entered 28 classrooms from a courtyard that did not drain properly during last week’s storms. Up to 50 carpenters, laborers and electricians have been working at the 1,060-student school day and night to repair the damage, Campbell said.

“I just did a walk-through, and it’s looking great,” she said Sunday afternoon. “The dampness is gone, there’s no mold, and all air tests have come back clean.”
