Mailboxes are the only structure that private owners are allowed to install within the right-of-way without a permit as a matter of convenience to the landowners. Neither the St. Croix County Highway Department nor U.S. Postal Service issue written permits for the placement of mailboxes within the public right-of-way.
The mailbox installation and support, along with the on-going maintenance and conformity with current U.S. Postal Service standards, are the responsibility of the property owner. All mailboxes placed within the public right-of-way are owned by the property owner and are placed there at the owner's risk.
The proper location and installation of mailboxes can minimize potential hazards and provide for safe travel, convenient mail delivery, and effectively accommodate maintenance activities. All mailboxes should be mounted at a height of 42 to 48 inches from the road surface to the bottom of the mailbox. Mailbox posts need to be a minimum of 2 feet off the shoulder (see drawing).
Mailbox supports must be designed so that if struck, it will bend or fall away from the striking vehicle to prevent severe damage to the vehicle or injury to the traveling public. Massive supports such as telephone poles, heavy metal posts, concrete posts, antique farm equipment, or other similar items are prohibited.
Mailbox must meet minimum/maximum standards of support, setting and size. A plastic mailbox becomes very brittle in the winter. An oversized mailbox may collapse from the weight of the snow. The issue of public safety will be the basis of the Department taking any action to have individuals repair, replace or relocate mailboxes.
