Call 811 to reach your local one-call center. Ticket rules and ticket life differ by state. Wait for the marks before you dig.

LineScout’s ticket reminder is for Texas. Your saved Texas tickets stay on this phone and show again when the map is back in Texas. LineScout does not list other states’ 811 websites or ticket rules.

Official ticket websites (link out only — we do not scrape, embed, or submit for you): the Texas811 Portal at portal.texas811.org, and the homeowner GeoCall form at txgc.texas811.org (the old txhop.texas811.org site redirects there). Confirm on texas811.org if a link ever changes.

Texas 811 basics

Locate mark colors (APWA)

Give notice in time. Texas Utilities Code § 251.151: notify a notification center not earlier than the 14th day before excavation begins, and not later than the 48th hour before it begins, excluding Saturdays, Sundays, and legal holidays (at least two working days). Saturday notices have a special start-time rule in § 251.151(b). Read the current statute. This is not legal advice — verify before you dig.
Wait for the marks and a positive response before you start. Short-notice tickets that start work early can violate the law.
Respect the tolerance zone. The One-Call statute does not set one distance for every utility. For RRC-regulated underground pipelines, 16 TAC § 18.2(21) and § 18.10 define a tolerance zone as half the pipeline’s nominal diameter plus at least 18 inches on either side of the outside edge; use care and often hand or vacuum excavation there. Industry / APWA practice commonly uses 18 inches from the marks for other facilities. Do not assume a line is exactly under the paint or at a standard depth.
Ticket life. Railroad Commission rules (16 TAC § 18.1(h), read with § 18.1(g)) set the life of a line locate ticket at 14 days, and periods stated in days are working days unless otherwise specified. The RRC excavator brochure says routine tickets expire in 14 working days. Marks are valid 14 days from positive response (16 TAC § 18.6(b)). You and an operator may agree in writing to a longer life (§ 18.3(f)). If work is not finished, refresh the ticket for the area still to be excavated (§ 18.3(e)).
Protect the marks. If they are destroyed, request a remark / update through 811 — do not guess.

APWA Uniform Color Code (16 TAC § 18.6(a) requires pipeline marks to conform to this code):

The APWA Uniform Color Code is the common U.S. color scheme for locate marks. Confirm local rules with your one-call center.

RED	Electric power lines, cables, conduit, lighting
YELLOW	Gas, oil, steam, petroleum, or other hazardous liquids/gases
ORANGE	Communications, alarm or signal lines, cable TV
BLUE	Potable water
GREEN	Sewer and drain lines
PURPLE	Reclaimed water, irrigation, slurry
PINK	Temporary survey markings
WHITE	Proposed excavation

Welcome to LineScout

Quick how-to:

Tap GPS for your location, or search Midland / Abilene in the search bar.
Toggle layers (Simple mode keeps the most-used ones).
Tap a pipeline, well, or station for details.
Save this area caches station pins + RRC vectors for offline (not basemap tiles).
Search stations or sort by nearest to you.

Planning only. This is not a locate ticket and not “safe to dig.” Call 811 before excavating. Station hours/prices may be outdated — call ahead. Parcel lines are approximate, not a survey.

Texas is the full-coverage area: official RRC wells, laterals, and pipelines statewide. Official lease names cover 25 counties and 14 RRC offshore Gulf areas so far, stations cover the Permian–Abilene area, and city utilities/parcels are Midland (and Taylor parcels) only. The rest of the U.S. is a basic map only (no stations, city utilities, or pipeline maps outside Texas yet). Read the (have a Texas attorney review).

I understand this is a planning tool only, I will call 811 before digging, and I will not treat map features as surveyed or live station pricing.

About locate marks

This is not legal advice. Confirm requirements with Texas 811 and, if needed, a licensed Texas attorney. LineScout is a planning aid only.

Outside Texas: you can record marks anywhere, but ticket rules and ticket life differ by state. Call 811 to reach your local one-call center. The Texas rules below apply to marks in Texas only.

Locate marks in this app are your field records of paint or flags you actually saw after an 811 locate. They are not a locate, not a ticket, and not a reason to dig. Always call 811 before you dig. Call 811 does not auto-dial; it opens the in-app Dig Safe screen.

Marks are stored on this phone only (IndexedDB key pipefinder_locate_marks_s5). They are not uploaded and are not shared with other drivers until a developer backend exists. LineScout does not ship sample or invented marks.

Colors follow the American Public Works Association (APWA) Uniform Color Code: red electric; yellow gas, oil, steam, or petroleum; orange communications / telecom / CATV; blue potable water; purple reclaimed or irrigation; green sewer or drain; pink temporary survey; white proposed excavation.

In Texas: Railroad Commission of Texas rules at 16 TAC §18.1 state that, unless an excavator and an operator otherwise agree under §18.3, the life of a line locate ticket is 14 days, and that time periods stated in days in that chapter mean working days (Saturday, Sunday, and legal holidays are not working days). Official ticket life starts when notification is given to the notification center, not necessarily on the Date marked you type here.

This app fades a mark and labels it “EXPIRED — historical reference only” after 14 weekdays (Monday–Friday) following the Date marked you entered (default today). It does not automatically subtract official legal holidays, and it does not start the clock from the official 811 notification time. Treat that fade as an in-app reminder, not an official determination. Confirm expiration and refresh rules with Texas 811. If work continues, refresh the ticket as required.

Depth, owner, and ticket fields are whatever you type. Depth is labeled “as stated, not measured.” Do not treat a photo or pin as proof of a facility’s location, depth, or status. Marks can be incomplete, misplaced, or out of date. The 811 tolerance zone and safe excavation practices still apply.

You can add a point from GPS (accuracy is shown when the phone reports it) or a map tap, or draw a line by tapping several points along a marked run. You can list, search, filter, edit, delete, link a mark to a job site already on this phone, and export or share. Share and export include a safety disclaimer.

Sources to confirm: Texas 811, Texas Utilities Code Chapter 251, and 16 TAC Chapter 18 (including §18.1 and §18.3). This screen is a summary for operators of this app, not a complete statement of the law.
