Rainier Superintendent Michael Carter's home sustained "significant" damage after a Saturday evening fire, but no one was injured, said Columbia River and Fire Rescue Chief of Operations Eric Smythe.
Carter said no one was home during the fire. He and his wife were attending a play in Portland.
"It's devastating. ... I wouldn't wish the trauma of a fire on anybody," Carter said.
Carter said the house is uninhabitable and that he and his wife are in temporary dwellings for the time being.
"The community has been very supportive. The police and fire department did an outstanding job at helping us out," Carter said.
Smythe said fire crews from Clatskanie, Scappoose and Longview also responded to the home, which is on a bluff visible from the Lewis and Clark Bridge.
Smythe said an investigation is ongoing, but initial indicators suggest the fire started outside the home. He said the two-story building sustained at least 50 percent damage and is uninhabitable.
