Commercial and industrial HDD for conduit, fiber, water, sewer and gas in Plano, Frisco, McKinney, Allen and across the county, by a Southlake-based team working in the north metroplex.
Texas Hawk is headquartered in Southlake and our crews are based in the Dallas–Fort Worth metroplex, so Plano, Frisco, McKinney and Allen sit inside our everyday service area. Collin County is one of the busiest places in the state for new commercial development, and our 300+ crew network can mobilize nationwide when a program is bigger than one crew.
Collin County is chalk and clay country. The USGS state geologic map shows Austin Chalk as nearly half of the surface, with clay-rich formations and river deposits making up most of the rest. Site soil borings set the final tooling and fluid program; this is the general picture.
Austin Chalk is at the surface across about 49 percent of the county. Chalk is a soft, fine-grained limestone that often bores well, but hard beds and weathered, sticky zones both show up, so tooling is chosen from the soil boring.
The Ozan Formation covers about 19 percent of the county and the Marlbrook Marl about 9 percent. Clay-rich ground like this sticks to tooling and moves with moisture, which makes fluid control and careful reaming important.
The Eagle Ford Formation makes up about 6 percent of the county. Shale near the surface weathers to heavy clay, and depth matters under slabs and pavements that react to moisture.
Alluvium covers about 8 percent of the county and terrace deposits about 4 percent, mostly along creeks and the East Fork of the Trinity River. Expect soft or sandy ground, shallow groundwater and flood-prone low spots, so crossings go deep with fluid containment in place first.
Pecan Gap Chalk, Wolfe City and Gober Chalk appear as thin slices in the eastern part of the county. A single bore can pass from chalk to clay, and we plan the entry and exit layouts for that change.
Soil data drives the bore profile, tooling, drilling fluid and vacuum capture. Hard or sticky ground changes the schedule, so we price and plan for it up front.
Collin County is a patchwork of county roads, fast-growing cities, a regional water district and state highways. Each owner has its own written rules, and we line them up early so they do not hold up mobilization.
County policy requires lines under any county roadway or paved driveway to be bored or tunneled and encased, with open cut allowed only for pipe of 30 inches or larger and extra fees. Rural bores must extend beneath all travel lanes plus five feet toward the ditch centerline; curbed urban bores must extend beneath the travel and parking lanes and two feet past the back of curb. A Notice of Proposed ROW Activity is filed online, and work cannot begin until it is approved.
Plano’s right-of-way rules call for bore drawings showing the diameter and start and end points, and a profile drawing where the bore crosses a main of 12 inches or larger. Longitudinal bores stay 9 feet from larger water and sewer mains and 5 feet from smaller ones, with 24 inches of vertical separation from city infrastructure. Permit review can take up to 10 working days.
McKinney’s right-of-way manual requires concrete streets and driveways to be bored, test holes at each water, sewer or storm crossing, and bore pits kept 5 feet off the roadway. Voids are pressure grouted, a sewer camera inspection may be required, and missile and jetting methods are not allowed.
Frisco requires contractors to register for right-of-way work, hold an approved right-of-way permit and have line locates in place before digging. Allen, Wylie and the other cities each have their own permit steps, which we confirm for the specific address.
Crossings of North Texas Municipal Water District water and wastewater pipelines go through design review and a pipeline crossing application. Those approvals take time, so they are requested as soon as the alignment is known.
Oncor Electric Delivery serves Plano, Frisco, McKinney and Allen, and the CoServ Electric, Fannin County, Farmers and Grayson-Collin cooperatives serve other parts of the county. Atmos Energy’s Mid-Tex Division runs gas in the metroplex. Collin County is in TxDOT’s Dallas District, where the utility owner files for any state right-of-way crossing.
Collin County keeps adding commercial campuses, corporate sites and utility-heavy projects, and local reporting in May 2026 described data center activity in Plano and Allen. The work is a mix of new development and infill beside live streets.
Plans, utility records and soil data reviewed up front, with the bore sized and set to meet each owner’s written crossing rules.
Texas811 notice at least two working days ahead, test holes or potholes at crossings, and county, city or water-district approvals started early.
Bore the path, track it, pressure grout where the owner requires it, and capture drilling fluid so it stays out of storm drains and creeks.
Daily production reports and as-builts for close-out.
On a rural county road the bore runs beneath all travel lanes plus five feet toward the ditch centerline. On a curbed urban road it runs beneath the travel and parking lanes and two feet beyond the back of curb.
Only for pipe of 30 inches or larger, and with additional fees. Lines under county roadways and paved driveways are otherwise bored or tunneled and encased.
Drawings that show the bore diameter and its start and end points, plus a profile where the bore crosses a water or sewer main of 12 inches or larger, with 24 inches of vertical separation from city infrastructure.
No. McKinney bans them, requires bore pits 5 feet off the roadway, test holes at utility crossings and pressure grouting of voids.
It depends on the owner. Plano’s review can take up to 10 working days, Collin County requires approval of its online notice before work starts, and water district and rail reviews run longer, so we start them first.
