What You Need To Know Before Digging on Your Property

Whether you want to install a pool or plant a tree, you need to know what’s underneath. Here, we explain what you need to know before digging on your property.

Underground utilities can run through front yards, side yards, and even areas that look untouched for years. When a shovel or auger hits something it shouldn’t, the consequences can range from a neighborhood outage to a dangerous gas leak or an expensive repair bill that follows you long after the project ends. Before you break ground, here’s what you need to know before digging on your property in Florida.

Start with 811, even if the job feels small

The smartest first step is to request a utility locate through 811. This free service exists for a reason: you cannot reliably “guess” where lines run, and older properties may have changed hands, been remodeled, or had service upgrades that shifted the underground picture.

Homeowners sometimes assume 811 is only for major construction. In reality, many everyday tasks can put you within striking distance of buried lines. Fence posts, sign posts, planting holes, irrigation work, pool and patio upgrades, and drainage improvements all carry risk—especially if you plan to use power tools like post-hole diggers or trenchers.

Make the request as early as you can, then wait for the marking process to finish before you dig. If your timeline slips because of weather, travel, or a change of plans, do not treat old paint as a permanent green light. Marks fade from rain or lawn work and can become confusing after a few days of foot traffic.

What the colored markings can tell you, and what they can’t

After you place a locate request, you will typically see spray paint, flags, or both on the ground. Those markings help you understand the approximate location of buried utilities, and they can guide your excavation plan. Still, markings do not guarantee you’ll avoid every hazard. Utilities can shift over time, soil can erode, and landscaping work can alter grades.

Marks also have limits: 811 generally focuses on “public” utilities, and it may not identify every line that matters on private property. That detail surprises many homeowners. A line serving a detached garage, a backyard lighting system, a well component, a private drain, or a buried propane line can sit outside the scope of what 811 typically marks. That is why you should treat 811 as a foundation, not the entire safety plan—especially on older lots or homes with additions.

Understand what 811 does and does not locate

Another thing you need to know before digging on your property is that 811 does not include everything. Homeowners can get into trouble when they assume “marked” means “they marked everything underground.” In practice, the utilities that 811 locates do not include everything that may be beneath the surface.

The 811 service only marks public utilities. If you plan to dig near a driveway, around a pool deck, or beside an accessory structure, you may need extra diligence to account for lines that do not fall under the public-locate umbrella.

Florida-specific digging risks homeowners frequently overlook

Florida homes bring their own quirks underground. You may deal with shallow utilities due to high water tables. You may face tight easements in planned neighborhoods, where multiple services share narrow corridors. You may also confront storm-related repairs and upgrades that happened quickly after major weather events, which can complicate the “as-built” reality beneath your lawn.

Salt air and moisture can speed up corrosion on older metallic lines and fittings. Frequent landscaping updates can also create a patchwork of underground components—irrigation lines, low-voltage wiring, French drains, and outdoor kitchen hookups—sometimes installed by different contractors over many years.

Plan your dig zone like a careful driver plans a route

Once markings appear, slow down and map your work area. Walk the route you intend to dig and look for signs that suggest buried infrastructure: utility pedestals, meters, valve boxes, cleanouts, cable junctions, and conduit emerging near walls. These surface clues typically reveal where lines travel underground.

Then think about how you will dig. Hand digging allows more control than power equipment. Narrowing the trench or hole size reduces your odds of contact. Shifting a project a few feet—moving a planting bed edge, repositioning a post, adjusting a path—can dramatically lower risk without changing the result.

This is also the moment to decide what “too close” means for your project. If you must dig near marked lines, treat the area with extra caution. Work slowly, use hand tools as you approach the suspected line path, and stop immediately if something looks unfamiliar.

Call again if conditions change

Many homeowners will start one project and discover a second one along the way. You begin with a sprinkler repair and decide to add lighting. You plan a garden bed and realize you want to install edging posts. If the scope changes, your original locate request may no longer cover the new dig area.

The same applies when heavy rain, landscaping crews, or routine yard maintenance disturbs markings. Florida storms can erase paint overnight. A lawn service can remove flags without meaning to. If you cannot clearly interpret the marks, request a fresh locate so you can proceed with confidence.

Know when to bring in a professional locator or contractor

Sometimes, the safest choice is to get professional help before you dig. If you manage a complex property with multiple structures, a long driveway, a seawall, or a history of renovations, you can encounter a web of private lines that standard marking may not reveal.

You should also consider professional support if your project involves deeper excavation, power equipment, or any work near gas service, electrical feed lines, or major water lines. In those cases, a small planning cost can prevent a major emergency.

Digging safely protects more than your yard

Digging incidents affect more than just your property. A cut cable can interrupt service down the block. A damaged water line can undermine soil and create sinkholes or washouts. A gas leak can force evacuations and bring emergency response into a quiet residential street.

Safe digging also protects your family in the moment. The best prevention is a routine you follow every time: request marking, confirm the work zone, dig carefully, and stop when something doesn’t match expectations. If you remember one rule, make it this: call 811 before digging. That single step turns a risky guess into a planned project.
