- My mailbox was knocked down by the snow plows. What do I do?
You can either call 651-430-4300 or Report a Concern (green button above). The Maintenance Supervisor will inspect any damage to mailboxes on county roads. Washington County does not replace mailboxes or posts damaged by the force of moving snow. A swing away style mailbox is designed to minimize the risk of damage from plowed snow and is what is suggested.
- I live on a county road. Who do I contact to have a swing arm mailbox installed?
All Washington County residents that reside on a county road may have a swing-away style mailbox installed for $75.00. Please submit a Mailbox Request Form to Washington County Public Works via email or mail to 11660 Myeron Rd N, Stillwater MN, 55082. For additional information, please call 651-430-4300.
- Who do I contact about a dead deer or other animal on a county road?
If the animal is located on a County Road or Road Right of Way, call 651-430-4300 or Report a Concern (green button above) and the animal will be disposed of. If the animal is located on a state or city street, you must contact the appropriate authority. If the animal is on private property, it is the responsibility of the property owner.
