A Principal that has elected to receive both Police and Fire/EMS Emergency Communications Services will pay one Assessment for service to its Police agency and one Assessment for service to its Fire/EMS agency. A Principal that has elected to receive only police or Fire/EMS Emergency Communications Services from Snohomish County 911 only pays an Assessment for the service so received.
