Underground Service Alert, known as "USA", provides a high quality Underground Facility Damage Prevention service to Central/Northern California. USA's purpose is to receive planned excavation reports from public and private excavators and to transmit those planned excavation reports to all participating members of USA who may have underground facilities at the location of excavation. The USA Members will either mark or stake their facility, provide information or give clearance to dig.

The One-Call System will not mark private or non-member utilities. The utility locating companies notified by your state One-Call system will locate and mark only primary public utilities, so it's up to you to keep track of what else is on your own property.

Private Utilities are the buried lines after the meter or main lines. If you have a curbside meter then your property will not get marked by One-Call locators. Other buried utilities that generally are not marked by One-Call include but are not limited to: sewer lines, private lighting, sprinklers, fire mains, secondary electric lines to detached garages, and septic lines.
