Steps
Call 811 or submit a locate request through the state one-call center's site at least the statutorily required lead time before excavation (commonly a few business days, but confirm the exact state requirement).
Mark the proposed fence line and post hole locations with white paint/flags before the locate request so utility locators can find the work area.
Wait for all affected utility members to respond or mark "clear" before digging; do not proceed based on a partial response.
Hand-dig or pothole within the required tolerance zone around any marked utility line rather than using a mechanized auger through the marked area.
Keep the locate request confirmation/ticket number on file as documentation of compliance in case of a later utility-strike dispute.
Known gotchas
811 covers utility-owned lines to the meter/point of service; private lines the property owner installed (irrigation, low-voltage lighting, a private propane line) are often not marked and need separate verification.
Locate tickets expire after a limited window that varies by state — a fence project that stalls mid-job may need a re-locate before digging resumes.
