Why 811 Isn't Enough for Commercial Excavation
The inescapable risk.
Public utility locators (Arizona 811) only mark utilities they own, which typically stops at the meter. Relying solely on 811 leaves your site exposed to unseen private lines, increasing the risk of costly utility strikes, SUE (Subsurface Utility Engineering) non-compliance, and severe project delays.
The solution is USI Locate
USI Locate sweeps the entire dig area. Our private locating services map every inch of your site beyond the meter, providing total visibility before you break ground.

Frequently Asked Locating Questions:
What is the difference between 811 and private utility locating?
811 (Arizona Blue Stake) only locates public utility lines up to the service meter. A private utility locator like USI Locate maps all privately owned utilities beyond the meter, across your entire commercial or residential property.
What areas in Arizona do you serve?
We provide commercial underground utility locating across the entire Phoenix metropolitan area, including Scottsdale, Mesa, Tempe, Chandler, Gilbert, Glendale, and Peoria, as well as statewide coverage for major projects.
