Area of Continual Excavation

Starting July 1, 2020, excavators and operators of California’s underground facilities will begin using Area of Continual Excavation (ACE) locate request tickets which are valid for one year as compared to the standard ticket length of 28 days. A 2016 change to CA law created the new ACE ticket which is available to farmers and certain flood control operators.
