As you work in your yard, take a close look at your mailbox. The U.S. Postal Service has guidelines on proper placement of a mailbox at the curb or edge of the street. Proper installation helps the mail carrier readily access your mailbox and ensures that it is located out of the way of passing vehicles, especially snow plow blades. Mail carriers may not deliver mail to a box they are unable to access due to height, snow, leaves, a parked car or any other obstruction. Retro-reflective house numbers for your mailbox may be purchased through the Washington Township Fire Department. Residents may call 433-3083 for an order form. Follow the attached guildelines.
