Statute & History
Arizona Revised Statutes (ARS) § 28-1106 C. states “A local authority with respect to highways under its jurisdiction may prohibit by ordinance or resolution the operation of trucks or other commercial vehicles or may impose limitations as to the weight of vehicles on designated highways.” On November 5, 2019 the Coconino County Board of Supervisors approved Ordinance 2019-15, which rescinded the previous County Oversize/Overweight (OSOW) Ordinance that had established a process for the issuance of OSOW permits. Also on November 5, 2019 the Coconino County Board of Supervisors approved Resolution 2019-38, which establishes weight restrictions on routes under County jurisdiction and provides public notice to transporters.
All oversize or overweight transporters that plan to utilize any portion of Arizona state or federal highway networks must contact the Arizona Department of Transportation (ADOT) to obtain a permit. ADOT will in turn notify the County of any roads under County jurisdiction that may be affected by the movement of the vehicle. If only a County road will be traversed, and a state or federal route will not be traversed at any point during the movement, then the transporter will be responsible for consulting Exhibit A of Resolution 2019-38 and will be required to notify the Engineering Division of the County Public Works Division, via email, at least 48 hours prior to movement. The transporter must ensure that the transport vehicle can safely traverse all structures along the planned route and not exceed allowable weight limits. The transporter will include in their email the vehicle dimensions, gross vehicle weight, axle configuration, axle loading and the list of County Structures being traversed as well as the structures’ weight capacity. An email with this information or questions shall be sent to firstname.lastname@example.org.
Permit / Impact Fees
While the County does not charge permit or impact fees for OSOW vehicles, damage to structures caused by OSOW traverses will be assessed and compensation sought per ARS § 28-1107.
