Before Yard Grading: Who Accounts for Private Underground Lines?
Before yard grading, discuss private underground lines with your contractor as well as the Tennessee 811 notification process. Utility responses do not necessarily account for every owner-installed connection. Bring records of irrigation, outdoor power, and other buried systems, then agree who will arrange any additional locating and resolve unanswered questions before excavation begins.
Understand the gap between utility responses and private lines
Tennessee 811 explains that it connects excavators with member utilities; it does not perform the marking itself. Its private-locating guidance identifies systems such as irrigation, invisible pet fences, propane connections, and power serving detached buildings as examples that may require separate attention. The public-to-private boundary is not always the property line. Ask about the specific service rather than assuming that every connection beyond a fence has the same ownership.
For an owner planning a yard correction in Gallatin or elsewhere in Middle Tennessee, this is a coordination question to raise while discussing the work area. Contact Tennessee 811 before digging and follow its current process. This planning checklist is not a clearance to excavate or a substitute for the contractor's excavation procedures.
Build an inventory around what the property actually uses
Start a short document with one entry for each outdoor system you know about. Give each entry a recognizable name, the building or equipment it serves, the installer if known, and the records available. Add a separate column for questions. An honest unknown is more useful than an unverified route drawn confidently across a plan.
Ask yourself: Was anything added after the house was built? Did a previous owner install a backyard feature? Does a tenant manage equipment outside the main building? Who services the irrigation system? These prompts are intended to recover property history, not to identify buried routes from appearances.
For a commercial property, ask maintenance staff and the property manager to review the same inventory. Avoid collecting several informal versions that disagree about which system is being discussed. Name one person to consolidate corrections and send the updated document to the project contact.
Send records with context, not implied certainty
Useful material to offer includes installation drawings, invoices identifying the installer, and photographs taken during earlier work. Label each item with its date and origin. If a sketch came from a former owner's memory, say so. Ask the contractor and locator what records will help their review rather than treating an old drawing as proof of today's conditions.
Keep your photo labels specific: identify the equipment shown and the direction the camera faced. Do not add a guessed depth or underground path. If you cannot find records, tell the project team early and provide contact information for anyone who may have them. Do not dig exploratory holes to complete the inventory.
Make locating coordination visible in the project scope
Before accepting a mobilization date, ask who is handling the 811 request, who is discussing possible private facilities, and who will arrange additional locating when needed. Ask whether that coordination is included in the proposal or is a separate owner-arranged service. A vague note that utilities are the owner's responsibility deserves a conversation about the actual tasks and contacts.
Request a simple handoff: the agreed work area, the contact responsible for outstanding questions, and the next review point. If you later add a walkway or widen the grading area, notify that contact before treating the expanded work as approved. The useful outcome is a shared scope, not merely a folder containing a ticket number.
Milliken's current grading page lists excavation and yard regrading, while its drainage page includes drainage excavation and utility-related services. When requesting an evaluation, include your private-system inventory and ask how it should fit into the proposed work. Do not assume that a general service listing means a separate private-locating service is included.
Frequently asked questions
Does a Tennessee 811 request cover my irrigation system?
Do not assume it does. Tennessee 811 lists irrigation among private facilities that may need separate locating. Discuss that system specifically with your contractor and the appropriate locating provider.
What should I do if I have no installation drawings?
Report that gap when planning the project. Supply known equipment names and installer contacts, and ask what additional investigation is needed. Do not replace missing records with guessed routes.
Should the grading quote name a private-locating allowance?
Ask the contractor to explain whether additional locating is included, excluded, or pending review. The important point is a written understanding of who arranges the service and how any separate cost will be addressed.
