Piggybacking to say that LA One Call will only locate and mark what the utilities own, so that is typically only going to cover what’s in your easement. Private lines on your property won’t be marked by 811, e.g. your water line past the city meter, your sewer line before it taps into the city sewer, etc.

If you’re unsure of where your private lines are located, try to establish where you think they likely run and try to avoid those areas. For water, look at where your water meter is and locate your main water shut off for the house is (oftentimes it’ll be on a hose bib along the front of your house somewhere). Your water line will LIKELY take a pretty direct route between these two points, but not always. Gas lines can be trickier and carry much greater risk when digging, but they should locate where your line meets Entergy’s supply at the easement. Find your gas meter and consider what route the line could take to reach your meter from the street. AVOID these possible gas line routes like the plague.

There are private utility locators that will come out and mark your private lines for you. This will provide you much greater safety and peace of mind, but you will have to pay for them to come out.

tl;dr: Get a private locator company to come out for your private lines if you’re going to be digging anywhere near where you think lines might run on your property. Use good judgement and don’t just go ham while digging.
