Stop Fire
Before It Reaches
Your Structure.
A defensible space perimeter slows fire around your structure. A strategic fuel break stops it from crossing your property in the first place. ClearGround plans every break from drone data — not a field walk — and places them where fire behavior models show the highest lateral spread risk on your specific terrain.
A Fuel Break Is
Fire's Dead End
on Your Property.
Fire needs three things: heat, oxygen, and fuel. You can't eliminate heat or oxygen on a wildfire scale. But you can eliminate the continuous fuel pathway that lets fire travel laterally across your land.
A strategic fuel break is a cleared corridor — wide enough and positioned correctly — that removes the fuel connection between incoming fire and the brush adjacent to your structure. It doesn't stop every spark. It stops the sustained, lateral spread that turns a distant fire into a structure fire.
The difference between a fuel break that works and one that doesn't is placement. A break placed in the wrong location — even the right width, the right clearing — doesn't interrupt the fire path. ClearGround plans from the drone data, not from a windshield survey.
Fire in the Hill Country travels upslope up to 4× faster than on flat ground. A fuel break placed at the top of a slope is nearly useless — the fire has already reached full speed before it arrives. ClearGround places breaks at the base of upslope approaches and across dominant wind corridors, calculated from the pre-clear RTK terrain model.
Where We Place Breaks —
And Why.
Fuel break placement is a terrain decision, not a preference decision. ClearGround plans from the pre-clear RTK model — slope grade, aspect, dominant fuel corridors, and structure approach paths all factor into the break system design.
The highest-priority break position on any sloped Hill Country property. Fire climbs slope 4× faster than flat terrain. Breaks placed at the base of upslope approaches intercept fire at its highest acceleration zone — before it reaches full speed and ember load.
Hill Country prevailing winds typically run south to southeast. Breaks placed perpendicular to dominant wind direction interrupt lateral fire spread driven by wind rather than slope. Particularly critical in open pasture and ridge-top property configurations.
Even with a defensive perimeter, fire can channel toward a structure through draws, canyon corridors, or narrow fuel-connected paths. ClearGround identifies these corridors from the drone terrain model and places targeted breaks across approach vectors the structure perimeter alone can't address.
Hill Country Brush —
Every Fuel Type Handled.
Fuel break construction and brush reduction in the Hill Country means working with a mix of species at different densities and terrain types. Here's how ClearGround approaches each one.
The dominant fuel break target in the Hill Country. Dense stands, volatile oil content, and continuous canopy make cedar the primary lateral fire carrier. FAE mulching head on the CAT 299D3 XE processes standing cedar and accumulated deadfall in a single pass. No burn permits. No hauling.
Live oak, shin oak, and native scrub species provide lower fire risk than cedar but still contribute to continuous fuel loads in break corridors. Selective clearing preserves mature oak canopy while eliminating understory brush and ladder fuels that connect ground fires to the canopy.
Dry native grass and accumulated deadfall are the ignition layer — the fuel that catches first and carries fire to standing brush. Break corridors that eliminate standing brush but leave dense grass or deadfall still allow fire to cross. ClearGround's break treatment addresses all fuel layers, not just canopy.
Cedar regrows aggressively in cleared corridors — a break that isn't maintained begins losing effectiveness within 18–24 months. Annual maintenance visits clear regrowth before it reconnects the fuel corridor, keeping your break system functional and your documentation current for insurance renewal.
RTK-Planned. Machine-Built.
3D-Verified.
WE MAP THE FIRE PATHS
BEFORE WE BUILD THE BREAKS.
RTK drone flight produces a centimeter-accurate 3D terrain model of your property — slope grade, aspect, dominant vegetation corridors, fuel load density, and structure approach paths. Break placement is calculated from this model, not from a field walk. You see the planned break system overlaid on your terrain before a machine rolls.
PLANNED FROM DATA.
BUILT TO SPEC.
CAT 299D3 XE with FAE mulching head clears the break corridor to planned width. CAT 308E2 CR mini excavator handles root grubbing, break-face treatment, and slope work where the mulcher can't access. Ground fuel layer is treated to bare mineral soil or low-fuel mulch across the full break width — no residual fuel left in the corridor.
WIDTH CONFIRMED.
CORRIDOR MEASURED.
On multi-break projects, we fly a progress scan at each completed break segment. Width, position, and surface treatment are verified against the planned layout. If a break needs adjustment — terrain variance, unexpected fuel density — it's caught in the scan before the next segment, not at project close.
EVERY FOOT OF BREAK
MEASURED AND DOCUMENTED.
Post-construction RTK scan confirms total linear footage of breaks, average and minimum width at every segment, surface treatment depth, and before/after comparison showing the fuel corridor interruption. Every break is measured against its design spec — deviations noted and addressed before sign-off.

Built for Break Construction.
Fuel break work in Hill Country terrain needs a mulcher for brush volume, an excavator for root grubbing and slope work, and a drone system that plans and verifies from above.
High-flow compact track loader with FAE mulching attachment. Processes the standing cedar and brush volume in break corridors at high throughput. Compact footprint navigates break paths without widening the corridor beyond design spec.
Compact-radius mini excavator for root grubbing, break-face surface treatment, and slope work inaccessible to the mulcher. Zero tail swing prevents accidental widening of the break corridor. Handles the full-depth ground fuel treatment that makes a break effective, not just clear.
RTK drone + base station combo generates the terrain model that drives break placement planning and confirms construction accuracy. Independent of cellular networks — works at full accuracy in remote Hill Country locations where NTRIP fails.
Fuel Break & Brush
Reduction — FAQ
In Hill Country terrain, 30–50 ft minimum width depending on slope grade and dominant fuel species. Steep slopes require wider breaks because fire approaches faster and throws embers farther. ClearGround determines width from the terrain model — not a standard rule-of-thumb.
Yes — but placement matters more on steep terrain than flat. Upslope breaks placed at the base of slope grades are most effective. ClearGround's terrain model calculates slope grade and aspect before planning break position, so breaks are placed where fire behavior data says they'll perform.
Yes. The pre-clear RTK scan flags desirable vegetation adjacent to the break corridor. The CAT 299D3 XE's compact footprint and the excavator's zero tail swing both minimize impact outside the planned clearing width. Native oaks and protected trees adjacent to the break are identified in the model and avoided.
Cedar regrowth begins within 12–18 months in cleared break corridors. Dry grass accumulation creates new ground fuel faster on disturbed soil. Annual maintenance keeps your breaks effective and your documentation current — and costs a fraction of the initial construction each cycle.
Fuel breaks are documented with the same RTK-verified 3D model and measurement report as defensible space work. ClearGround's deliverable package includes a formatted compliance report carriers can review and archive. The break system is shown in the before/after model — width, position, and fuel corridor interruption all measurable.
Yes — and for most Hill Country properties, this is the right approach. Defensible space creates the structure perimeter; fuel breaks intercept fire before it reaches that perimeter. ClearGround scopes and plans both from the same pre-clear RTK model, and delivers a single documentation package covering the full system.
