JULIE stands for Joint Utility Locating Information for Excavators.
Per their website, “You may be surprised by what's buried in your yard. That's because most electric, gas, water, sewer and telecommunications companies are delivering utility services underground. Protect yourself and your family. State law requires you to notify JULIE at least two business days (excludes weekends and holidays) before any digging project regardless of the project size or depth. Even if you are digging in the same location as a previous project, notify JULIE. This is a free service.”
CALL 811 or 1-800-892-0123 to place a local request. JULIE's Call Center agents process local requests 24 hours a day, 365 days per year. JULIE’s administrative offices are open 8:00 am to 4:00 pm.
