Excavation around Canyon Lake starts with Hill Country ground: cedar and oak on the slopes, limestone under the soil. In 2002 floodwater went over the spillway for the first time since the lake was finished in 1964. It cut a 64-acre gorge below the spillway and stripped the ground down to limestone. A pad or a trench on a lake lot can mean digging into rock.
Global Contractors LLC is an excavation contractor based at our yard in Pleasanton, south of San Antonio. Since 2006 the company has done excavation and demolition, much of it on commercial and government sites. Around Canyon Lake that means pads, footings, driveway cuts and trenches, plus land clearing and site preparation. Call (253) 606-9497 and we will look at the lot and put a free estimate in writing.

Comal County is prairie in its eastern quarter and Hill Country across the rest. The Handbook of Texas puts the northwestern three-quarters at 750 to about 1,500 feet above sea level. Its loam runs from shallow to deep and has proved better for grazing than for crops. The Guadalupe River and Canyon Lake drain the hills in the middle of the county.
The Canyon Lake Gorge shows what sits under that loam. The 2002 flood exposed Cretaceous limestone there, with fossils and dinosaur footprints 110 million years old. The Guadalupe-Blanco River Authority describes faults, fractures and seeps in the gorge limestone, where the Trinity Aquifer is exposed.
Footings and trenches for underground utilities can hit limestone close to the surface. Depth to rock changes from one lot to the next. On a slope, dirt work also has to shape a level pad and keep runoff off the lot below. We look at the site before we price any of it.
The Hill Country side of Comal County carries more timber and less grass than the prairie to the east. The same Handbook entry lists live oak, mesquite and Ashe juniper, the tree most people call cedar. A lake lot that sits empty for years can close in with cedar and brush. Before anything gets built, that growth has to come off the pad and the driveway.
A juniper control paper from a Texas university calls Ashe juniper a non-sprouting species: cut it down and it does not come back from the stump. That makes cedar a good match for forestry mulching, which grinds it where it stands. Where a pad or driveway goes in, the excavator pulls the stumps and roots.
Mature cedar and oak in a ravine need a second look before clearing starts. Texas Parks and Wildlife says golden-cheeked warblers nest only in mixed Ashe juniper and oak woodland in central Texas. The nests sit in ravines and canyons, built from long strips of cedar bark and spider webs. If your tract has that kind of woodland, ask about the warbler before the mulcher goes in.
Canyon Lake has no city government. The Handbook of Texas calls it a dispersed, unincorporated region around FM 2673 and along the lake shores. It takes in the older communities of Startzville, Sattler, Hancock and Cranes Mill. The lake at its center has a surface area of 8,240 acres and a sixty-mile shoreline.
Impoundment began on June 16, 1964, and rapid building around the lake followed. The first subdivisions included Canyon Lake Hills and Canyon Lake Village. By the mid-1980s more than eighty neighborhoods had been built around the lake. Sattler and Startzville grew into commercial centers, and Canyon City grew up on FM 306 below Canyon Dam.
The area had 9,975 people in 1990 and 16,870 by 2000. Census estimates put Comal County at 161,466 people in 2020 and 201,628 in 2024. A new home on a hillside lot starts with clearing and a level pad. Where a house or slab already stands, demolition comes first.
Because Canyon Lake is unincorporated, the Comal County Engineer's Office is the permit office. The county publishes a list of the permits that may be required before building in its unincorporated areas. A septic, or OSSF, permit application goes in with a design from a registered engineer or sanitarian. A TCEQ-licensed installer sets and permits the septic system itself.
Lots near the river and the lake shore can sit in the regulatory floodplain. Development there needs a Floodplain Development Permit, and the county's development rules include a Flood Damage Prevention Order. The 2002 flood shows why that matters. In one summer week, more than 34 inches of rain fell in the upper Guadalupe watershed.
A driveway installation or other work in the public right-of-way takes a PIPROW permit. Comal is also one of the counties in TCEQ's Edwards Aquifer Protection Program. TCEQ must review and approve a plan before anyone builds on the aquifer's recharge or contributing zones, two of the zones its program lists. We plan the work around the permits that apply, and Texas 811 gets the call before we dig.

Land clearing services for lots, acreage and ranch land around San Antonio. We clear brush, mesquite, cedar, trees and stumps with excavators, skid steers and a forestry mulcher.

Forestry mulching grinds cedar, mesquite and brush into mulch right where it stands. The chips stay on the ground as cover, so nothing leaves the property.

Underbrushing clears cedar and brush out from under the trees you want to keep. The canopy stays, and everything cut is ground into mulch on the spot.

Right-of-way clearing opens utility, pipeline, road and drainage easements through brush, cedar and trees. The mulcher grinds the corridor in place, and the excavators pull stumps where a line or a road goes in.

Mesquite grubbing pulls each tree out with its root crown, so it is much less likely to sprout back. We grub pasture and fence lines around San Antonio with excavators, skid steers and dump trucks.
