When you call 811 or hire a private utility locating service, you're paying for expertise and documentation—but many customers don't know exactly what paperwork they'll walk away with. Understanding the records you receive protects your project timeline, ensures compliance, and gives you proof of due diligence if anything goes wrong.
What You Get After a Locate Request
Once a locate technician finishes marking utilities on your property, you'll receive a locate ticket or work order documentation. This packet typically includes:
- A completion ticket with the date, time, and scope of the locate
- Marked diagrams or photos showing where utilities were (and weren't) marked
- A list of utilities that were contacted and their responses
- Details on any utilities that couldn't be located
- Technician contact information and company details
Most standard locate jobs generate 5–8 pages of documentation. More complex sites with multiple utility types or difficult-to-access areas may produce thicker files.
The Locate Ticket: Your Critical Record
The locate ticket is the backbone of your documentation. It serves as proof that you followed proper procedures before digging. This ticket should clearly state:
- Your project address and the area marked (usually outlined in white paint or flags)
- Which utilities were successfully located (electric, gas, water, fiber, sewer, etc.)
- The date the locate was performed and its expiration (typically 28–30 days in most states)
- Whether the locate was marked or "not located" for specific utilities
- Any notes about access issues or hazardous conditions
Keep this ticket on-site during excavation. If something goes wrong—say you nick a fiber line—your documentation proves you called 811 first. That distinction can mean the difference between paying for repairs yourself or having the utility company liable.
Diagrams and Marked Maps
Professional locators provide marked-up site plans or photos showing where utilities run across your property. These visuals are invaluable for your own planning. Look for:
- Color-coded marks (usually following the ANSI standard: red for electric, yellow for gas, blue for water, green for sewer, orange for fiber)
- Depth notations where relevant
- Measurements from reference points (property lines, building corners)
- Timestamps or weather conditions noted (helpful if conditions change rapidly)
Some advanced locating services use GPS mapping or drone imagery, especially for large commercial sites. If your project covers more than a few acres, ask whether the locator offers digital mapping—this costs $150–400 extra but eliminates guesswork.
Utility Clearance Letters and No-Locate Responses
If a utility company confirms "no facility in this area," you'll receive a clearance letter or "no-locate" response as part of your documentation package. These letters are essential. They prove:
- You contacted the utility (or it was contacted on your behalf via 811)
- The utility confirmed no lines exist where you want to dig
- You have written proof of that confirmation
Without this documentation, you're digging blind. Missing clearance letters from even one utility can jeopardize your project's legal standing, especially on commercial jobs or near public right-of-way areas.
Digital vs. Paper Records
Most locating companies now offer both formats. Digital records arrive via email within 24–48 hours and are searchable, shareable, and easily stored. Paper records are handed on-site and work as backup. Request both if your project requires:
- Archival records (you may need them years later for maintenance or resale)
- Quick sharing with contractors or engineers
- Compliance with municipal regulations
How Long You Should Keep Documentation
Don't discard these records after your project ends. Keep them for at least three years, longer if your property is in an area with frequent utility work or if you're selling. Buyers and future contractors will want proof that utilities were properly located.
Store scans in cloud storage alongside project photos. If a utility company later claims you damaged their line, you'll have timestamped, dated evidence of your due diligence.
Frequently Asked Questions
Q: What if utilities weren't marked because they couldn't be located? The "not located" designation is still documented and protects you—it means you tried. Call the utility directly to request a private locate if that section is critical to your project.
Q: Can I use old locate documentation from a previous owner? No—locate markings expire (typically 28–30 days) and new utility installations may exist. Always request a fresh locate before digging.
Q: Who pays for locate documentation? 811 locates are free; private locates usually cost $100–300 depending on property size and complexity, and documentation is included.
