City crews will post signs indicated reduced speed limits of 35 mph -- down from 50 mph -- on state Route 31 north of Creekview Drive to Quail Hollow Drive, around the first week of August.

Since Mill Valley has experienced continuous growth over the past five years, Route 31 is experiencing a higher volume of traffic, especially during rush hour, Marysville City Council member Tracy Richardson said.

"The idea is that we put safety first," she said. "The congestion on 31 has just gotten to the point where lives are at risk."

Richardson said her concern is notifying the community of the speed limit change ahead of time.

"My concern is that folks aren't surprised and they understand that we've lowered the speed limit to protect everyone," she said.

City engineer Valerie Klingman said the city is finalizing its plan to inform the public.

"We will be using pretty much every means possible to help get the message out," Klingman said.
