Call 811 Before You Dig Deck Footings

Last spring, a guy in Carmel rented a two-person auger and started digging holes for a new deck. He thought, "I'm not using heavy machinery, just some post holes, no big deal." About 18 inches down, the auger caught something. A few seconds later, the internet went out for his whole block. He'd hit the fiber line that feeds the neighborhood. The repair bill—over $2,000—came out of his deck budget. And he still had to call 811 before digging the next time.

That's the thing: you don't need a backhoe to cause real damage. A shovel, an auger, even a post hole digger can cut a buried line. And if you want to build a deck in Indianapolis, especially a multi-level one with deep footings, you have to call 811 before digging. It's not just a good idea. It's the law in Indiana.

Why You Have to Call 811 Before Digging for Deck Footings

Lots of folks think calling 811 is only for big construction jobs. But a deck footing goes deep—often 3 to 4 feet in Indiana to get below the frost line. That's plenty deep to hit a gas line, electric cable, or fiber optic line. And in Indianapolis backyards, those lines are often running right through where you want to put posts. Especially in neighborhoods like Broad Ripple, Meridian-Kessler, or Irvington, where fiber companies have been installing new lines in the last few years. If you skip the call and hit something, you're on the hook for repairs. That could be thousands of dollars. Plus you might knock out your own gas or internet. Not worth it.

And yes, even if you're just using a hand auger or a post hole digger, you still need to call 811 before digging. The law in Indiana doesn't care what tool you use. If you dig and hit a line, you're responsible. So call.

How Indiana 811 Works: Timing, Tickets, and Positive Response

When you call 811 (or submit online at Indiana 811), you need to do it at least two full business days before you plan to dig. So if you want to start digging on a Monday, you should call by Wednesday or Thursday of the previous week. But in spring, when everyone wants to build decks in Carmel and Fishers, the locators get backed up. Build in extra time. We usually tell folks to plan for a week between calling 811 and actually digging. That way if marks need to be refreshed or something gets missed, there's cushion.

You'll need to give them your address, the county, a description of the work area (like "backyard, 20 by 30 area, digging 4 feet deep for deck footings"), and your contact info. Then each utility company—Citizens Energy Group for gas, AES Indiana for electric, and various telecom and water folks—will send someone to mark their lines. You should get a "positive response" from each one. You can check the status online or call 811 to confirm all utilities have marked before you dig. If a utility doesn't respond, don't start digging. Call 811 again and tell them.

One thing a lot of people don't realize: 811 only marks public utility lines up to the meter or point of service. That means the gas line running to your grill, the electric line to your detached garage, irrigation pipes, landscape lighting—those are private lines. 811 won't mark them. If you have a big multi-level deck that crosses the yard, you might have private lines in the way. That's where a private locator comes in. We coordinate private locates when we see the need.

The rule is simple: call 811 before digging any hole for a deck footing. Even if you're pretty sure there's nothing down there.

Reading the Paint: Utility Colors and the Tolerance Zone

Ever see those little flags and spray paint marks in a yard and wonder what they mean? The color code is set by the American Public Works Association (APWA). Red is electric, yellow is gas, orange is communication or fiber, blue is water, green is sewer. White usually marks where you plan to dig. So when you look at your backyard and see a yellow line running right through where you wanted a post, you can shift the post a couple feet to miss it.

But you can't just dig right next to a mark. Indiana has a "tolerance zone" around each marked line—24 inches on each side. Inside that zone, you're supposed to hand dig or use vacuum excavation. No power augers, no backhoes. If you get too close with a machine, you risk nicking the line. And if you do hit something, stop digging right away. Call the utility company immediately. Don't try to bury it or fix it yourself. They'll send someone out to assess. Usually, the person who hit the line pays for repairs. So better to be careful.

Marks don't last forever. Rain, mowing, even kids playing in the yard can wipe away paint or move flags. In Indiana, an 811 ticket is good for about a month. If your project takes longer than that, or the marks fade, you need to call 811 again for a re-mark. Don't guess where the lines were. That's how accidents happen.

How Locates Affect Your Deck Design, Permits, and Timeline

In Indianapolis, most decks need a permit from the city or county. In Marion County, that's the Department of Business and Neighborhood Services. They want to see your footing plan and depth. If you can show that you called 811 and adjusted your post locations to avoid utilities, your permit review goes smoother. We coordinate the 811 timing with your permit application so you're not waiting extra days.

The clay-heavy soil around here and the freeze-thaw cycles mean your footings have to go below frost depth—usually around 36 to 42 inches, but check with the local building department because it can vary. That's deep. And in older neighborhoods, the utilities might be shallower than you expect. We've seen gas lines just 12 inches down in some yards because of previous landscaping or erosion. So locates are essential.

Rear-lot easements are common in Indianapolis suburbs. That means the back few feet of your yard might have a utility easement where lines run parallel to the property line. If your multi-level deck extends to the back, you might have to design around that easement. Sometimes we can cantilever a deck over an easement instead of putting footings directly on top of the line. Or we shift the whole deck a few feet. Early locates let us plan that before we start digging.

Also, think about other parts of your outdoor project. If you're adding a fence around the deck or enclosing a patio, those need locates too. As a fence contractor, we can use the same 811 ticket to cover the fence post digging. If you have a concrete patio and we're building a deck over it or installing posts through it, we need to know what's under that concrete. Gas lines to grills, electric for lighting, even cable TV lines can be buried under a patio. And when it comes to railings—code-compliant guardrails need solid posts, and those posts often need footings as well. So the same locates apply. We build railings that meet Indiana guardrail height code, and we plan their post locations to stay clear of utility marks.

That repair bill from hitting a fiber line can eat into your deck budget fast. If you're worried about costs, we've got a guide on deck financing options in Indianapolis to help you plan.
