Campaign Signs - Placement on the Island

There is no specified starting date for posting campaign signs. Here are some sign placement tips:

  • Campaign signs must comply with the size limitations specified in the temporary signs section of the city code (MICC 19.06.020). Maximum size according to the sign code is six square feet.
  • Campaign signs can be placed on private property with the permission of the property owner.
  • Campaign signs within the parking strip portion of the right-of-way generally require the consent of the abutting property owner.
  • Campaign signs can be placed on some public right-of-way such as traffic islands and isolated parking strips or roadside areas, as long as there is no line of sight problem, traffic safety issue or maintenance issue (e.g. damage to irrigation lines) created by the placement of the signs. Signs cannot exceed 60 inches in height to preserve sight distances.
  • City staff asks that all campaign signs be removed within 48 hours after an election.

It is best to direct your concerns or complaints to the appropriate campaign committee(s).

If any political campaign signs are picked up by City personnel, they will be available at the City Hall's loading dock for campaign committee pickup.
