MARYSVILLE — At approximately 2:33 a.m. Aug.31, the Marysville Fire District was dispatched to a commercial fire in the 5200 block of 100th Street NE. Firefighters arrived at 2:41 a.m. and located a fire in a classroom portable at Cascade Elementary. Firefighters initially were impeded by down power lines which did not allow firefighters to attack the fire through the door. Instead the firefighters had to cut openings in the wall of the portable to enter the structure to extinguish the fire. The fire was brought under control within 20 minutes and no injuries were reported.

The fire dollar loss is approximately $250,000 and the Marysville School District is working on plans to replace the portable classroom.

More than 13 firefighters battled the blaze with mutual aid provided by Snohomish Fire District 22 (Getchell).

The fire is being investigated by Snohomish County Fire Marshal’s Office.
