School resumed on Wednesday, December 6, after evacuation orders for the Westridge Valencia neighborhood were lifted the evening of December 5.[8] However, Simi Valley Unified School District closed all schools on Wednesday due to poor air quality.[4] The fire continued to grow and by December 7 one structure had been destroyed and California Department of Forestry and Fire Protection (Cal Fire) has expressed concern about strong offshore winds which could cause the fire to grow.[3] Power went out for over 8,880 customers.[13] One firefighter was injured and airlifted to a burn center.[14][15] Overnight, no fire growth was observed by Cal Fire and firefighters continued to mop up the fire and maintain perimeters.[1]
By the morning of December 8, power had been restored to all customers in the area.[13] On December 9, firefighters continued to mop up the area and keep the fire within the perimeter, bolstering containment lines. During an evaluation of the Peter J. Pitchess Detention Center, they discovered that minor structures were damaged or destroyed, bringing the total destroyed buildings to six and damaged structures to three.[16] All evacuation orders were lifted by December 9. The Rye Fire burned 6,049 acres (24.48 km2), and threatened 5,460 structures.[1] On December 12, the Rye Fire was fully contained, with no further increases in size.[1] At its height, over 900 fire personnel fought the Rye Fire.[1] The cause of the fire remains under investigation.
