The City of Sammamish is a Seattle and Bellevue bedroom community located East of Interstate 405 approximately 10 miles. The population is approximately 65,733 as of 2018. Located on a plateau, the city is bordered by Lake Sammamish to the west and the Snoqualmie Valley to the east. In 2015 they won the Washington State award for the safest city.
The Sammamish Public Schools policy is to have multiple 12” flashing beacons at each school with signs that read “Speed Limit 20 MPH when Flashing”. Having signs that flash for certain durations during specific hours while school is in session has proven to decrease driver speeds and increase awareness and safety for vulnerable pedestrians who are predominately children.
The issue, however, is that the Sammamish School District is comprised of two school districts, Lake Washington SD, and Issaquah School District, which on a combined basis include (3) High Schools, (4) Middle Schools, and (11) Elementary Schools for a total of (42) flashing school beacon signs. That means countless technician hours programming school schedules, repairing beacons, replacing LEDS, and performing regular preventative maintenance, not to mention, traveling to each beacon every time a school has a schedule change.
