Call Before You Dig: Arizona Blue Stake 811 Rules Explained

Before any excavation project in Arizona — whether it's a professional trenching job or a DIY fence-post hole — there's one call that matters more than almost anything else: Arizona Blue Stake, dialed simply as 811.

What Blue Stake / 811 actually does

Arizona Blue Stake is the state's utility-notification service. Call (or submit a request) before you dig, and participating utility companies mark the approximate location of buried water, gas, electrical, and communication lines on your property with colored flags or paint — hence "blue stake," though different colors mark different utility types. It's a free service, and it exists specifically to prevent utility strikes.

Why this matters beyond convenience

Hitting a buried utility line isn't just an inconvenience — it can mean service outages for you and your neighbors, expensive repair costs, and in the case of gas or electrical lines, genuine safety hazards. Arizona law requires notification before excavation in most circumstances, which is part of why "call before you dig" isn't just good practice — it's often a legal requirement.

How far in advance to call

Utility marking typically takes a few business days after a request is submitted, so this isn't a same-day step — it needs to be planned into your project timeline before any digging starts, wherever in Arizona the project is.

What gets marked (and what doesn't)

Blue Stake coordinates marking for utility company lines up to the point they enter your property in most cases. Private lines a previous owner or contractor installed on your property — an irrigation line to a shed, for example — may not be part of the standard utility locate and are worth flagging separately if you know about them.

Why we call for locates on every job

Even with professional-grade equipment and experienced operators, excavating near unmarked lines carries real risk. Confirming utility locations before digging is a standard part of how we operate on every trenching, grading, or utility-line project we take on across Arizona — not an optional add-on.
