Yavapai supervisors adopt microtrenching standards to speed broadband buildout

The Yavapai County Board of Supervisors unanimously approved updated county roadway design standards May 20 that add a new microtrenching section intended to streamline broadband installation while protecting pavement life.

Joe Huot, operations manager for Public Works, described microtrenching as “a very small cut in asphalt” (microtrench widths as narrow as 1½–3 inches and depths typically 16 inches with cover) and walked the board through the proposed standards, including wheel‑path limits, a requirement for flowable slurry backfill, a reduced overband (1 inch on each side of the trench), and moratoria on microtrenching for roads recently chip‑sealed (3 years) or overlaid (5 years). Huot said the standards require anchor points for conduit every 10 feet at depth and ongoing maintenance obligations from the installer until a future surface treatment.

Board members questioned inspections, warranty mechanisms and bonding for long‑term maintenance; staff acknowledged there is no bonding requirement for right‑of‑way work but said the county will rely on franchise agreements, insurance, frequent inspections and contractual obligations to ensure repairs. Supervisor Jenkins praised the cautious, evidence‑based approach and noted staff looked at other jurisdictions’ microtrenching histories when drafting the standards.

The board voted to adopt the publicized standards as modified during the discussion, approving the resolution and giving staff direction to finalize permit language and inspection regimes.

Why it matters: Microtrenching can reduce cost and time to bring fiber to rural and suburban homes; the standards aim to balance faster broadband deployment with protections for local road infrastructure and taxpayer investments.

Next steps: Public Works will finalize permitting documents, inspection and maintenance processes, and publish the permit and standards so contractors can apply for microtrench work under the new rules.
