Mailbox Installation Guide

Mailbox guidelines during winter months


The Department of Public Works is asking residents to assist us in preventing damage to your mailboxes during the upcoming winter plowing season and avoid unnecessary mail interruption. Occasionally coming into contact with a mailbox is a common obstacle snowplow operators face during storm activities. Richton Park employees are conscientious in performing their duties, though there are occasions in which a snow plow will damage a mailbox that is too low and/or too close to the curb line. Setting your mailbox to the height regulations and far enough back on the curb will minimize or eliminate any possible damage from snow removal operations.

A properly installed mailbox should not extend past the curb line and be 41 inches from the lowest point of the unit to the ground. Adding a newspaper box to the bottom or side of your mailbox increases the surface area of the mailbox. No part of the mailbox can extend past the back of the curb.

It should be remembered that weather, frost and age will affect the placement of a mailbox and annual maintenance by the resident is recommended. If the mailbox extends past the back of the curb and is damaged by a city plow the village accepts no liability for damage.

These notices are being delivered to those whose mailbox does not conform to the standards, regardless of the degree of nonconformity. The Department of Public Works thanks you for your cooperation. For questions please call the Department of Public Works at 708-481-8950.
