Officials are investigating the cause of a small fire on Wednesday that led to water damage in Laurelwood Academy southeast of Springfield. Pleasant Hill and Goshen Fire Districts were called to the private secondary school about 5 p.m. Wednesday for a report of smoke coming from the building. The school, affiliated with the Seventh-day Adventist Church, is on Jasper Lowell Road. Firefighters discovered smoke coming from the third floor and found that the school’s fire sprinklers had extinguished a small fire on that floor, Pleasant Hill-Goshen Fire Chief Andrew Smith said. The Lane County Sheriff’s Office and Oregon State Police are helping in the investigation to determine the fire’s cause.
