Spokane Valley recently installed flashing school zone speed limit signs at  Chester Elementary (3525 S. Pines) and Orchard Center Elementary (7519 E. Buckeye). The new signs have flashing beacons to remind drivers to go 20 miles per hour when the speed limit is in effect, usually when students are arriving at or leaving the school. The signs were partially paid for by a grant from the Wasington Traffic Safety Commission. Watch for the signs and for children when you drive by.
