Call 811 Before You Dig

Steps to Safe Digging

Plan Your Project
- Before contacting Sunshine 811, gather the details of your project, including where and when you plan to dig. If you hire someone to dig, they are responsible for submitting the locate request.
Contact Sunshine 811
- Submit a free locate request online or call 811 at least two full business days before digging. Your request notifies participating utility companies so they can mark the approximate location of underground utility lines. Private utility lines are not marked through Sunshine 811.
Wait the Required Time
- Allow utility companies two full business days to locate and mark underground utility lines. Weekends and legal holidays do not count toward the required waiting period.
Confirm
- Before digging, verify that all utility companies listed on your ticket have responded and that all underground utility lines have been marked or cleared. If markings are missing, unclear, or a utility has not responded, contact the appropriate utility company before beginning your project.
Dig Safely
- Respect all utility markings and excavate with care. Florida law requires increased precaution when digging within the 24-inch tolerance zone on either side of a marked underground utility line. If your locate ticket expires before your project is complete, request a new locate before continuing to dig.
