Winter weather has arrived, bringing both snow and ice. That snow and ice can cause blocked mailboxes and slippery surfaces, that can prevent delivery. Letter carriers are instructed to refrain from delivering to locations that are inaccessible or too hazardous. If they’re unable to deliver your mail, they’ll hold it at the Post Office. Please bring ID. USPS is asking customers to clear enough snow from curbside boxes – at least six feet on both sides of the mailbox – so the carrier may approach and leave without backing his or her vehicle. Clear snow from both the front and back of cluster boxes. Walkways need to be cleared so as to allow enough traction to avoid slips, trips and falls. Steps – especially painted wood – must be clear of ice and snow and kept in good repair. Overhangs must be cleared of snow and ice to avoid injury.
