We want to reassure you that Woodbury has an extensive emergency plan. In compliance with California law, the Irvine Unified School District uses the Standardized Emergency Management System (SEMS) in its emergency plans and procedures. Response procedures are in place to activate the emergency plan. Each year the staff reviews and practices the plan in mock drills to ensure the safest and most efficient response to an emergency. State law requires each elementary school to conduct monthly fire drills, a lock-down drill, and a drop-and-cover drill as part of the emergency preparedness plan.
