California 811: Call Before You Dig in Modesto

If you've rented a roll-off from us for a fence replacement, a new patio, a deck rebuild, or any project where digging is part of the plan, there's a call you need to make before the shovels come out — and it isn't to us. It's 811. We get asked about this often enough at Dawes Dumpster Rental Modesto that it's worth laying out plainly: when you actually need to call, how the process works in Stanislaus County, and how it connects (or doesn't) to where your dumpster sits.

First, the short answer: does placing a dumpster require an 811 call?

No. Setting a roll-off container on an existing driveway, a paved parking area, or even bare lawn or dirt with nothing planned underneath it is not excavation. You're not breaking ground, so there's nothing to locate. If your project is "rent a dumpster, fill it with junk or debris, we haul it away," you can stop reading and go book your container.

Where it changes is when the same project that needs a dumpster also involves digging near where that dumpster will sit, or anywhere else on the property. That's genuinely common. A lot of the jobs that fill a 15 or 20-yard container — fence tear-outs and rebuilds, deck demolition, small landscaping overhauls — also involve putting something new into the ground. That's the piece that needs a call first.

What counts as "digging" for 811 purposes

California's rule doesn't care how big the hole is. It applies to any excavation that disturbs the earth, which in practice covers a lot of ordinary residential and small commercial work around a Modesto property, including:

• Setting new fence posts or replacing rotted ones in the same holes
• Digging footings for a shed, patio cover, pergola, or deck posts
• Trenching for a drainage line, French drain, or downspout extension
• Installing or repairing a sprinkler or irrigation line
• Putting in a mailbox post, flagpole, or new landscaping bed with any real depth
• Removing a tree stump or grinding roots below grade
• Any trenching for a new gas line, electrical run, or water line on the property

Notice what's not on that list: rolling a dumpster onto your driveway, dropping it on a patch of dirt for a weekend, or backing it up next to the garage. The container itself sits on top of the ground. It's the shovel, the post-hole digger, or the trencher that triggers the requirement — not the dumpster.

One practical wrinkle worth mentioning: if you're planning to place the dumpster directly on unpaved ground because you're clearing space for a new structure, and part of that same project involves digging footings a few feet away, get the locate done for the whole work area before anything starts. It's a lot easier to have utilities marked once for the entire footprint than to try to remember which corner is safe.

USA North 811: the real program covering Stanislaus County

The organization that handles locate requests for Northern California, including all of Stanislaus County, is USA North 811 (also seen written as USA North / USAN). It's a nonprofit that coordinates one-call notification to utility operators across 45 California counties, plus 17 counties in Nevada. If you're anywhere in Modesto, Ceres, Turlock, Oakdale, Patterson, or the smaller Stanislaus County communities, this is the outfit you're dealing with — Southern California residents use a separate service (DigAlert), but that's not us here.

The number to remember is the easy one: dial 811. That's the national three-digit number and it routes you to the right regional center automatically, so you don't have to know the organization's name or hunt down a phone number. USA North 811 also lists a direct line, 800-642-2444, and takes requests online at usanorth811.org for people who'd rather not call.

A few things worth knowing about how it actually runs:

• It's free. There's no charge to submit a locate request, and no charge for the utility companies to come out and mark their lines. This is a public safety service, not a paid inspection.
• It's required by law. California Government Code Section 4216 — the state's "call before you dig" statute — requires excavators, including homeowners doing their own digging, to notify the regional notification center before breaking ground. Skipping it isn't just risky, it's a legal requirement you're skipping.
• It covers every kind of digging, not just big construction jobs. The law doesn't set a size threshold for a hand-dug fence post hole versus a trenching machine. If you're disturbing soil, the notification requirement applies.

Why the law exists

Underground utility lines — gas, electric, water, sewer, fiber and cable — run through residential yards all over Stanislaus County, often closer to the surface and in less predictable paths than people expect. Hitting a gas line with a post-hole digger or a rented trencher isn't a hypothetical; it's the exact scenario this law is written to prevent. Beyond the safety risk, an excavator who digs without a valid locate request and damages a line can be held liable for the repair costs and any resulting damage, which is a genuinely expensive way to save a five-minute phone call.

And it's not just gas lines that make this worth doing. Cut a buried irrigation main and you're looking at a repair bill and a soggy yard. Nick a fiber or cable line and you may have knocked out internet for half the block, which tends to get noticed fast. None of these are as dangerous as a gas strike, but they're all avoidable with the same two-day phone call.

Reading the marks once they're down

When the locators come out, they use a standard national color code that holds across pretty much every utility in the country, not something specific to Stanislaus County. It's worth knowing before you're standing in your yard looking at a row of painted flags trying to guess what they mean:

• Red — electric power lines and cables
• Yellow — natural gas, oil, or other hazardous liquid lines
• Orange — communications, cable TV, and fiber lines
• Blue — potable water lines
• Green — sewer and drain lines
• Pink — survey markings and temporary reference points
• White — the color you used to mark your own proposed dig area in the first place

You don't need to memorize all of this, but knowing that yellow means gas and red means electric is the kind of thing that's genuinely useful the first time you're eyeballing a fence line and deciding exactly where the new post hole can safely go.

How the process actually works

USA North 811 lays this out as a straightforward sequence, and it holds true whether you're a homeowner replacing a fence or a contractor digging footings for a new patio cover:

1. Mark your dig area in white. Before you call, outline where you plan to dig using white paint, flags, or stakes. This gives the locators a clear target instead of "somewhere in the backyard."
2. Call 811 or submit online. Give them your address, a description of the work, and how deep you expect to dig. This creates a ticket number you'll want to hang onto.
3. Wait the required notice period. California requires at least two working days' notice before you can start digging, measured from when your ticket is submitted. Weekends and holidays don't count toward those two days.
4. Let each utility respond. Every utility operator with lines in the area gets notified through your ticket and sends someone out to mark their own lines with spray paint or flags, at no cost to you. You need a positive response from all of them, not just a couple, before you're clear.
5. Dig carefully around the marks. Once everything's marked and your two working days have passed, you can proceed — using hand tools and extra caution within roughly two feet of any marked line, which is standard practice even after a professional locate.

If a mark looks unclear, or a utility hasn't responded by the time your notice period is up, the guidance is to call 811 again rather than guess and start digging anyway.

Timing it with your dumpster project

Here's how we'd suggest sequencing it if your project includes both digging and a dumpster. Call 811 first, as soon as you know you'll be digging — even before you've nailed down a delivery date for the container. Since the notice period runs a minimum of two working days and can occasionally take a little longer if a utility is slow to respond, getting that ticket started early means it's not the thing holding up your schedule.

Once your locate is done and the marks are down, that's a good time to give us a call and get the dumpster on-site. You'll know exactly where the marked lines are, which helps with deciding placement anyway — you generally don't want a loaded roll-off sitting directly on top of a marked shallow line for the whole rental period if you can help it, even though the container itself isn't excavating anything.

For most residential jobs around Modesto — a fence rebuild, a small patio, a deck replacement — this whole locate step adds maybe two to four days to your planning timeline, and it costs nothing. Compared to the alternative of hitting a line, it's not a hard trade to make.

What this doesn't change about renting from us

To be clear, none of this adds a step to renting a dumpster itself. We're still a phone call away, same as always — (209) 284-1242, Monday through Saturday, 7:00 AM to 7:00 PM. Our compliance side (that's Tom Bradley's territory) keeps an eye on placement rules, including when a City of Modesto street-placement permit applies, but the 811 call is on the digging side of your project, not the dumpster side. If your job is straightforward removal — a garage cleanout, a roofing tear-off, yard debris — there's no locate request needed at all.

If you're not sure whether your specific project counts as excavation, that's a fair question to ask us when you call about sizing your dumpster. We can't do the locate for you and we're not the utility experts, but we've seen enough Stanislaus County projects come through to have a decent read on which jobs typically involve digging and which don't.

The bottom line

Placing a dumpster on your property, driveway, or an approved curbside spot doesn't require an 811 call. Digging fence post holes, footings, trenches, or anything else that breaks ground on the same project does. The call itself is free, takes a couple of minutes, and California Government Code 4216 makes it a legal requirement, not a suggestion. Dial 811, wait the required two working days for USA North 811's member utilities to mark their lines, and you're clear to dig. Then give us a call when you're ready to talk dumpster sizing for the rest of the project.
