Tips

  • If a driveway apron already exists at your site, you do not need a new Encroachment Driveway Permit to access the paved county road.
  • Encroachment permit fees are itemized per unit of work (per driveway, per linear foot of curb/culvert/utility line, etc.) rather than a single flat fee — call DDS Customer Service, (928) 817-5000, for a project-specific cost estimate.
  • Working within the right-of-way without an approved permit doubles the normal fee under the 'After the Fact' provision — always obtain the encroachment permit before starting work.
  • Review timelines vary by project tier per the Department of Engineering's A.R.S. §11-1605(G)-compliant Submittal Review Timelines table: 14 business days for a straightforward residential driveway/landscaping/minor traffic-control/special-event application (Type 3), 24 business days for a utility relocation/intersection/irrigation-facility application (Type 1), or 29 business days for a commercial-project application (Type 2). If the applicant does not respond to review comments within 30 business days, Yuma County considers the application withdrawn; after approval, the applicant has 30 business days to pick up the permit before it is likewise considered withdrawn.
  • Permits expire after issuance: Type 1 permits in 45 business days (extendable up to 180 days total across 3 extensions); Type 2 and Type 3 permits in 90 business days (extendable up to 1 year total).
