Madrona K-8 School will be closed again Tuesday and possibly through Wednesday as Edmonds School District officials conduct air quality testing in the building following a fire in the staff lounge Sunday night.

In an email to parents Monday afternoon, Madrona Principal Lynda Fischer said that the school district has contracted with Hawk Environmental Inc. for air-quality testing that cannot begin until Tuesday afternoon.

“The company intends to complete this by the end of the evening Tuesday, however, there is the possibility that it will take until Wednesday morning to get final results,” Fischer said. “If we have to close school for Wednesday, we will notify you as soon as possible, however, this notification may not occur until late Tuesday evening.”

“I realize the inconvenience this situation is causing many families,” she continued. “I want to share that I cannot be more pleased with response and presence of District staff in addressing this situation. Every effort is being made to restore our school to operating condition.”

The Sunday night fire caused more than $250,000 damage. No one was inside the building and there were no injuries. Firefighters from Snohomish County Fire District 1, Lynnwood and Shoreline were able to keep the fire contained to the faculty room, but the adjacent school office and the section of hall just outside the school office and faculty room had smoke and water damage.

Fire investigators determined the blaze started in a storage space off the faculty room. They were unable to pinpoint an exact cause, but noted there was nothing suspicious about the fire.

The school is located in Edmonds but draws students from across the Edmonds School District.
