Arizona Hydrovac & Excavation Regulations
Excavation laws, 811 requirements, and licensing information for Arizona.
Arizona requires excavators to contact Arizona 811 (formerly Blue Stake Center) before digging. The state's Blue Stake Law provides a comprehensive framework for underground facility damage prevention.
Hydrovac services are in high demand in Arizona due to rocky desert soils and extensive utility networks in the Phoenix and Tucson metro areas. Contractors must adhere to Arizona Revised Statutes regarding excavation safety.
