Elhi Hill to participate in lahar evacuation drill March 21

The Sumner-Bonney Lake School District is participating in a regional lahar exercise, which is designed to test and improve the ability to evacuate or shelter students and staff in the event of an incoming lahar from Mount Rainier. 

On March 21 at approximately 9 a.m., students attending Elhi Hill High School Program, and our other schools in the Sumner valley, will physically evacuate their school building. Elhi Hill students will walk this emergency evacuation route, safely escorted by school staff. If you do not want your child to participate, you may opt out of the lahar exercise by completing and returning this form (Spanish | Russian | Ukrainian) to your Elhi Hill by March 15.

What to expect 

  • Under staff supervision, with assistance from local police personnel, students will follow a designated evacuation route on flat, paved sidewalks with one street lane closed. 

  • Students will complete about 80 percent of the route, stopping before gaining significant elevation with an end at the Gordon Family YMCA (16101 64th St E).

  • Buses will transport students back to their school where they’ll complete the remainder of their school day as normal. Total time for the drill is approximately one hour. 

The District’s participation in this full-scale, regional lahar exercise, known to be the largest of its kind in the nation, includes surrounding school districts, cities, towns and emergency management agencies. SBLSD has worked closely with the Sumner Police and Public Works Departments to coordinate this exercise to ensure the utmost safety of everyone involved.
