Landscaping rock & mulch at 385 Azalea is in the bike lane and constitutes a hazard when cyclists have to take the lane to avoid the rock. Mailbox also protrudes over pavement, though it is hard to tell because of rock & mulch on pavement.. Postal regulations //www.usps.com/manage/mailboxes.htm clearly state that mailbox is to be 6-8 inches from pavement. This situation endangers cyclists and aggravates motorists. Cyclists are in the lane at this point only because of the obstructions.
