We plow the streets curb to curb, or as close as we can get. Whatever snow is left in front of mailboxes is the responsibility of the property owner to remove or at least make the mailbox accessible to the mail carrier. If we made a mistake and left an unreasonable amount of snow on the edge of the street, we will return and cut back as much as we can. Residents should evaluate the location of their mailboxes. According to postal guidelines, mailbox door faces should be nine (9) inches from the road edge to avoid contact with the plow; the bottom of the mailbox should be between 42" and 48" above the road surface. If your mailbox is installed per postal guidelines, very little further clearing effort on your part should be necessary at your mailbox to provide access for the postal carrier.
