This fall, people looking to drive around a stopped school bus will have 394 reasons to think twice about doing so.

The Mercer Island City Council voted unanimously to adopt an ordinance allowing the installation of cameras on school bus stop arms at its regular meeting June 20 at City Hall.

The city also voted unanimously to authorize the city manager to sign an interlocal agreement with the Mercer Island School District, with the amendment that the school district periodically reports to the city what safety projects are being funded from generated revenues.

In April, the Mercer Island School Board approved the use of cameras on school bus stop arms and voted to enter into a contract with American Traffic Solutions to provide the safety camera system. District officials stated stop-arm violations have become a daily issue.

Under the plan, cameras would be installed on the stop arms of five school buses. A bus paddle citation fine would cost violators $394, with $299 going to the school district to fund school zone safety projects. A vendor fee of $69 would go to American Traffic Solutions, $21 would cover municipal cost and $5 would go to law enforcement cost.

American Traffic Solutions would provide the city with a web-based system for officers to review and approve or deny violations, and would train officers and court staff to use the system.

According to data provided by American Traffic Solutions, 96 percent of violators do not receive another citation and the payment rate is 88 percent.

The council had to suspend its regular procedure of requiring first and second readings of all ordinances before adopting, which the council voted unanimously to do. Monday’s meeting marked the first reading of both the ordinance allowing cameras on school buses and the interlocal agreement.

The city, along with the school district, will hold a public information campaign before the camera system goes live at the beginning of the 2016-17 school year.

At the joint meeting between the city and school district in April, both City Council and School Board members expressed a desire to forego a grace period for violators. Mercer Island Police Commander Dave Jokinen said the public information period over the summer would count as the grace period.

“We’ll get the word out during the summer time and then when the system goes live at the beginning of the school year, it will be issuing citations,” Jokinen said.
