Local Keys Experience for Utility Locating
Keys-Based, Permit-Ready
Preconstruction and permit coordination, run by crews already on the islands.
Keys-Based, Permit-Ready
Our HQ and crews are based in the Florida Keys, with 15+ years navigating Monroe County permit processes and local utility corridors. We know the right-of-way review and underground clearance steps unique to the islands. GPRS project managers and general contractors rely on our knowledge of local permit operations and utility system mapping.
Storm-Season Utility Risk
Hurricane season runs June 1 to November 30, and post-storm repairs often shift surface conditions, obscure prior markings, and increase risk for contractors. We coordinate fresh private locating and documentation before every excavation to protect infrastructure. Schedule concrete scanning and video pipe inspection before digging to locate water, sewer, and gas pipes beneath the ground surface.
Problems We Solve
Key Utility Locating Risks in the Florida Keys
What is the difference between 811 and private utility locating? Many contractors assume a One Call ticket covers all risk, but in the Keys, private utility lines, owner-installed feeds, and permit timing create hidden hazards crucial to address before breaking ground.
811 Marks Only Public Lines
Sunshine 811 covers member-owned facilities, but private laterals and owner-installed lines remain unmarked. Underground lines including gas, sewer, and drainage pipes are often missed.
- Public utilities only
- Private lines not covered
- Risk of hitting owner-installed feeds
County Permit Timing
Monroe County right-of-way permits can take up to 14 days for review. Late locating can stall construction projects and delay installation work. Contact us early to sequence approvals.
- Up to 14-day review
- ROW approval before digging
- Early coordination prevents delays
Undocumented Laterals in Old Keys Properties
Monroe County median home year built is 1982, per Florida Health Charts. Many properties have undocumented lines, and private locating prevents strikes on underground piping systems crucial to protect. Homeowners and contractors face structural damage risk without proper scanning.
- Older infrastructure
- Unknown feeds
- Retrofit risk
Assuming 811 Covers All Risk
Even after an 811 ticket, contractors can hit private lines, irrigation power, or telecom. Private locating fills the gap and protects against cross bores and safe digging violations. One Call of Florida marks public utilities but leaves private utility systems unmapped.
- 811 not all-inclusive
- Private lines at risk
- Liability remains

Our Process
Our Utility Locating Process for Florida Keys Projects
- 01
Local Dispatch and On-Site Review
Our Keys-based crew arrives on site for a walkthrough and scope review. We confirm project needs, identify access points, and set response timing within the first visit. Note all underground utilities and surface conditions during the initial assessment. GPRS equipment is deployed to scan for pipes, cables, and sewer lines beneath the ground.
- 02
Preconstruction and Permit Coordination
We coordinate with Monroe County and local utilities, securing ROW permits and clearances before digging begins. Permit lead time is built into the schedule up front. Our team plays a crucial role in sequencing approvals so excavation stays on schedule and construction work proceeds without delays.
- 03
Private Locating and Documentation
Our team uses ground penetrating radar (GPR) and site-specific methods to identify private lines, laterals, and owner-installed feeds. Each finding is logged with detailed documentation. Scanning technology maps pipes, cables, and underground systems with precision. Video pipe inspection equipment locates sewer and drainage lines when GPR alone isn't sufficient.
- 04
Marking and Verification
We mark located utilities and verify tolerance zones per Florida law. Paint marks, flags, and maps are provided so the dig crew has every reference on site. Cutting or trenching can proceed once all underground lines are verified and marked for safe excavation.
- 05
Project Support and Closeout
We support your team through excavation, answer field questions, and provide post-locate documentation for compliance. The closeout package travels with the project record and includes all utility system maps and permit references.

FAQs
Utility Locating Questions
- What is the difference between 811 and private utility locating?
- 811 marks public, member-owned utilities; private utility locating maps everything 811 doesn't cover, including owner-installed lines and private laterals on your site. In the Florida Keys, that gap matters because private feeds, irrigation power, and telecom drops run across most commercial and multi-family parcels. Our team handles the private side so contractors aren't relying on a One Call ticket for risks 811 was never designed to address. Public utilities are marked by Sunshine 811, but private utility systems require separate locating services. 811 marks public utilities, is free and required by law, and does not cover owner-installed or undocumented lines. Private locating marks private lines and laterals, is contractor-arranged and fee-based, and maps all lines to fill the gap.
- How does pricing work for private utility locating jobs?
- Private utility locating is custom-quoted based on site size, complexity, and permit needs. Our team reviews the scope, confirms which utilities are in play, and names every inclusion in writing before work begins. There are no bait prices, and we don't carry "varies" line items. For most commercial sites, a written quote comes back within two business days of the walkthrough. You pay only for the scope we quote, with no hidden fees or equipment charges.
- What if my project is just outside your listed service areas?
- Contact our team. If your project is near the Florida Keys, we may be able to accommodate with advance notice. Our crews dispatch from the Keys and Southwest Florida, so projects on the edges of our footprint are often workable with scheduling lead time. Send us the address and scope and we'll confirm whether we can cover it before you commit a timeline. We've handled jobs from Fort Lauderdale to Naples when project timing and crew availability align.
- How long do I have to wait after calling 811 in Florida?
- Florida law requires at least 2 full business days' notice before excavation. Plan ahead so the 811 wait doesn't compress your dig schedule. Our team typically sequences the 811 ticket alongside the private locate and any Monroe County ROW permit, which keeps all three on the same timeline rather than stacked end to end.
- What payment options do you accept?
- We accept check, ACH, and wire transfer for B2B projects. Our team works on standard contractor billing terms, with invoicing tied to project milestones on larger scopes. Contact us for any special billing needs, including AIA pay applications for GC-managed projects. You pay according to the agreed schedule, with no upfront deposits required on most jobs.
- How accurate are your locate markings?
- We document every finding so the basis of the locate package is clear: method used, depth where obtainable, signal confidence, and anything that could not be confirmed. Locating is a field measurement rather than a guarantee of what is underground — abandoned or unmarked lines, poor soil conductivity, and rebar all affect a signal, which is why Sunshine 811 notification and careful hand-digging inside the tolerance zone still apply. Call (305) 292-3369 if a marking does not match what you find and we'll come back out.
- What if I'm not satisfied with the locating results?
- Contact us immediately if you have concerns about the locating results. Our team will review the documentation against field conditions and, if needed, return to re-verify at no extra cost. Most concerns trace back to surface changes, recent storm activity, or undocumented feeds added after the original locate, and we'd rather come back and confirm than leave a contractor digging on a question mark.
- How do I get started with a private locate in the Keys?
- Call (305) 292-3369 or use our contact form to request a project review. Our team will confirm scope, schedule your locate, and coordinate all required permits. For preconstruction work, we recommend reaching out as soon as the dig dates are on your schedule so the ROW permit and 811 ticket don't compress against your excavation window.
