The fire was first reported shortly before 5 p.m., according to 911 calls listed in California Highway Patrol reports. One call said there was a lot of black smoke coming from the school, located on Lake Street.
Lake County Fire Assistant Chief Willie Sapeta said recycled rubber used on the playground caught fire. He said it could have been caused by someone tossing a cigarette on the ground in that area.
He said an engine was there for only five to 10 minute before the fire was out.
There was no damage, according to Sapeta.
