A many as 60 of the trees on Orange Grove Ave., the "county road" running from Michillinda Blvd. to Santa Anita Ave., could be endangered by a proposed road-widening project currently under consideration by Arcadia and Sierra Madre. The street would be widened from 30 to 36 ft. since the street is considered too narrow for the trash bins that residents often leave in the road, constituting a hazard.
