USA North 811 provides a free and effective Damage Prevention Service that protects the communities and underground facilities in Central / Northern California, and Nevada.

 

History

USA North 811 began operation in May of 1975 & incorporated as a 501 (c)(6) Non Profit Mutual Benefit Corporation in 1986. Our objective is to receive planned excavation reports from public or private excavators and to transmit those planned excavation reports to all participating utility members of USA North 811 who may have facilities in and around that excavation site. Our members will either: 1) mark or stake the horizontal path of their facility, 2) provide information about the location of their facility, or 3) advise the excavator of clearance, for facilities that they own.
