On Sept. 18 and Sept. 19, crews will add paint striping on the rooftop of the Friends of Costco Building (also known as Forest A), which will create some odor. Fans will be used to help dissipate the smell. This work will occur from 8 a.m. to 6 p.m. Please email construction@seattlechildrens.org or call 206-987-8000 with questions.
