Austin infill. Tight lots. Heritage trees. HOME Initiative. Compact radius machine. RTK-documented from day one.
Residential
Lot Prep
Clearing
Residential lot prep clearing is where compliance and speed compete on the same small site. Austin's Heritage Tree Ordinance, Critical Root Zone setbacks, HOME Initiative density requirements, and tight lot geometry mean every prep job is a precision operation — not a production mulching pass. The CAT 308E2 CR compact radius machine is built for exactly this: it fits on a 50×100 lot, works within CRZ boundaries, and produces RTK-documented clearing from pre-clearing survey through post-clearing verification.
Residential Lot Prep.
Tight Sites. Precise Boundaries. No Penalties.
Every other scope in this portfolio operates on rural or semi-rural acreage where the primary challenge is density, terrain, or scale. Residential Lot Prep Clearing is different — the challenge is proximity. Heritage trees with CRZ setbacks, neighboring structures within feet, utility lines overhead, and City of Austin development code requirements all operate on the same small lot simultaneously. The clearing has to be precise, documented, and defensible.
The $10K–$50K Penalty
That Never Happens When CRZ Is Mapped First.
Austin's Heritage Tree Ordinance protects trees meeting diameter thresholds — 19"+ for most species, 8"+ for live oak and several others — from removal without a permit. More importantly for lot prep work, it protects the Critical Root Zone of those trees from any soil disturbance, grading, or construction activity. The CRZ is the area within a radius (in feet) equal to the tree's trunk diameter (in inches) — meaning a 24" live oak has a 24-foot CRZ radius. Violating a CRZ during clearing or construction carries fines of $10,000–$50,000 per tree.

Four Residential Lot Types.
One Compact Radius Machine.
Residential Lot Prep Clearing serves a range of lot configurations — from Austin urban infill sites under the HOME Initiative to Hill Country residential lots with significant vegetation and larger footprints. The scope and compliance requirements differ by lot type; the machine and the RTK documentation infrastructure are the same across all of them.
50×100 to 75×150 urban lots in Austin's older neighborhoods — Bouldin Creek, Zilker, Hyde Park, Travis Heights — where HOME Initiative density allows multiple units on what was a single-family lot. These sites carry the most complex compliance picture: heritage trees with CRZ setbacks that may cover a significant portion of the lot, existing slab or structure to work around, neighboring structures within 5–10 feet, and overhead utility lines.
Heritage tree CRZ setbacks may cover 20–40% of the lot. Compact radius machine required — standard excavator tail swing will violate CRZ or hit neighboring fence. Austin DSD tree survey often required before permit issuance. No burn or haul-off on urban lots.
Single-family teardown lots in Austin and inner-ring suburbs where the existing structure is being demolished and the lot is being cleared for a new build. Tree and vegetation clearing is typically combined with slab removal and debris clearing. Heritage tree protection is critical — the development value of the lot depends on retaining heritage trees that add appraised value and cannot be replaced at any cost.
Demo debris must be separated from vegetation clearing scope. Heritage trees may be within the existing building footprint setback — CRZ documentation protects the developer from liability if the tree declines after construction regardless of clearing. Post-clearing scan serves as the pre-construction baseline for the builder.
0.5–3 acre lots in Austin's ETJ and surrounding cities — Cedar Park, Round Rock, Dripping Springs, Bee Cave, Lakeway — where suburban subdivision lots carry significant cedar and live oak vegetation that needs clearing before construction. Less constrained than urban infill but still subject to Austin or county-level heritage tree regulations depending on jurisdiction.
Jurisdiction determines heritage tree applicability — Austin city limits have the strictest ordinance; ETJ and surrounding cities have varying regulations. Pre-clearing survey confirms which trees require protection under applicable code. Cedar presence means mulch-in-place is preferred over haul-off for material management.
1–10 acre rural residential lots in the Texas Hill Country where the clearing is the first phase of a cabin build, custom home construction, or ranchette development. Larger footprint than urban infill but often carries the most significant vegetation — mature cedar monoculture, dense mixed forest, or overgrown agricultural land that needs comprehensive clearing before site design can begin.
County or city ordinance applies depending on location — Hays, Travis, Blanco, Gillespie, and Kendall counties all have varying tree protection requirements outside Austin city limits. Dense cedar may require Forest Clearing scope in addition to lot prep clearing for the full site preparation. Post-clearing Digital Twin serves as the existing conditions baseline for the architect and builder.
CAT 308E2 CR.
Compact Radius. Fits Where Others Don't.
Residential lot prep on urban and suburban sites has a machine constraint that most clearing contractors don't address: a standard excavator's tail swing extends several feet beyond the machine body during rotation, and on tight lots that tail swing will violate CRZ setbacks, hit neighboring fences, or damage existing structures. The CAT 308E2 CR is specifically configured to eliminate that problem.
The Machine That Fits Where Standard Equipment Cannot.
A standard 8-ton excavator has a tail swing radius — the distance from the machine's center of rotation to the counterweight — of approximately 8–10 feet. On a 50×100 Austin infill lot where a heritage live oak's CRZ extends 20 feet from the trunk, and the neighboring structure is 8 feet from the property line, there is no safe operating position for a standard excavator. The tail swing will violate one constraint or the other.
The CAT 308E2 CR's compact radius configuration reduces tail swing to within the machine's track width — meaning the machine body and counterweight stay within the same footprint as the tracks. The machine can rotate fully without the counterweight extending into CRZ zones, neighboring property, or overhead utility line clearance requirements. This isn't a minor operational advantage — it's the difference between a machine that can safely operate on the lot and one that cannot.
For pool builders and infill developers who have previously had clearing contractors tell them "we can't work next to that tree," the compact radius machine is the answer to that problem. The CRZ can be respected at the centimeter level and the machine can still operate productively on the rest of the lot.
Residential Lot Prep Process —
Documented From Day One
Every Protected Tree Located. Every CRZ Boundary Mapped.
Before any machine enters the lot, a Mavic 3 Enterprise RTK drone surveys the full property. Every tree is located to ±2cm accuracy. Diameter at breast height is assessed for each tree meeting or approaching protected species thresholds under the applicable ordinance. CRZ radius is calculated and mapped for every protected tree — the result is a georeferenced overlay showing the clearing envelope within which the machine can safely operate.
For projects going through Austin DSD permit review, the survey data can be packaged as a Heritage Tree documentation submission — confirming tree locations, DBH measurements, and CRZ boundaries in the format Austin's Development Services Department accepts. This is a standalone deliverable available as an add-on for projects requiring formal DSD submission prior to permit issuance.
Boundaries on the Ground Before the Machine Rolls.
CRZ boundaries are physically flagged on the lot before the clearing machine enters. The flagging corresponds to the RTK-mapped boundaries — not a visual estimate from trunk position. The operator has both the physical flags and the digital CRZ overlay on their machine display throughout the clearing operation. There is no ambiguity about where the CRZ boundary is at any point during the job.
For lots where the CRZ boundary passes through the designated clearing zone — a common situation where a heritage tree's CRZ extends into an area that otherwise needs clearing — the clearing plan defines the exact boundary where machine activity stops and hand-clearing or no activity begins. That boundary is the same boundary in the pre-clearing survey, the physical flagging, and the post-clearing verification scan.
CAT 308E2 CR. Tight. Precise. Every Pass Documented.
The CAT 308E2 CR with FAE head works the clearing zone defined in the plan — processing vegetation, trees, cedar, and undergrowth within the clearing envelope while staying outside every CRZ boundary. The compact radius configuration allows the machine to operate productively within feet of CRZ setbacks without risk of tail swing encroachment. Material is mulched in place at chip level — no haul-off on residential lots, no burn permits in urban areas.
For lots with significant root extraction requirements — particularly where cedar root crowns in the building envelope need to be removed before foundation or pool work — the 308E2 CR handles both clearing and root extraction in the same mobilization. Root extraction within CRZ zones is prohibited regardless of equipment — but extraction of non-protected vegetation root crowns within the clearing zone is addressed by the same machine used for the clearing.
Every Heritage Tree Confirmed. Every CRZ Respected.
Post-clearing RTK drone survey maps the cleared lot at the same accuracy as the pre-clearing baseline. Every heritage tree is at the same location, with the same measured DBH, and the CRZ radius around each tree is confirmed undisturbed in the before/after overlay. The machine didn't go there — and the RTK scan confirms it.
This post-clearing verification is the compliance documentation. For any future inquiry by Austin DSD, a neighbor, an HOA, or a lender — the RTK record shows the clearing was executed within the approved envelope. For pool builders and infill developers, it's protection against any future claim that heritage tree decline was caused by the clearing operation.
Cleared Lot in 3D. Builder Baseline. Compliance Record.
The before/after 3D Digital Twin of the cleared lot is delivered within 48 hours of clearing completion — hosted on Pix4D Cloud, accessible via shareable link from any browser. The pool builder, architect, landscape designer, or general contractor who arrives after clearing gets a survey-grade 3D model of the cleared lot as-existing — not a photo on a phone and a verbal description of what was done.
The Digital Twin includes the heritage tree locations, CRZ boundaries, and clearing envelope overlaid on the post-clearing surface — so the next contractor working on the lot has the compliance context they need before their scope begins. A pool contractor who sees the CRZ boundary before excavation begins is significantly less likely to create a CRZ issue with their equipment than one arriving to a cleared lot with no documentation of where the protected zones are.

All pricing includes the pre-clearing heritage tree and CRZ survey, physical CRZ flagging before machine entry, clearing operation with compact radius machine, post-clearing CRZ verification scan, and before/after 3D Digital Twin. Highlighted rows are the most common residential lot prep scopes. Lots with significant limestone requiring rock milling are quoted separately after site scan. Same-day clearing and Land Reclamation is available for lots where full reclamation is the combined scope.
Residential Lot Prep
Clients
Residential lot prep has the tightest ICP focus of any scope in the portfolio — the clients are almost always builders, developers, or homeowners in the Austin metro who need a cleared, compliant lot ready for the next trade.
Pool builders and landscape contractors on Austin lots who need vegetation cleared before excavation, foundation prep, or landscape installation — and who have had the "we can't work near that tree" problem with prior clearing contractors. The compact radius machine and CRZ documentation solve both the access problem and the liability problem in one scope.
Austin infill developers and custom home builders working on HOME Initiative lots, teardown-rebuilds, and inner-suburb custom sites. These clients need clearing that is fast, compliant, and documented — because the clearing is a condition for permit issuance and a liability exposure point for any future claims about heritage tree damage during construction.
Residential property owners in Austin or the Hill Country who own a lot and are preparing it for construction — a custom home, ADU, guest house, or major landscape renovation. They need the clearing done right the first time, with documentation that protects their relationship with the city, their neighbors, and their future builder or architect.
What Sets ClearGround Apart
on Residential Lot Prep
The RTK heritage tree survey and CRZ mapping is done before the clearing machine is even scheduled — not the morning of the job. The clearing envelope is defined from data, physical flags mark the boundaries on the ground, and the operator has both physical and digital reference throughout the operation. No guessing, no "close enough."
The CAT 308E2 CR compact radius machine fits on a standard 50×100 Austin infill lot, enters through a standard gate opening, and operates within CRZ setbacks that eliminate standard excavators. This isn't a workaround — it's the purpose-built machine for residential lot work in constrained urban environments.
The post-clearing RTK scan confirms CRZ respect as a documented, timestamped record — not as a verbal assurance from the operator. For developers, builders, and homeowners facing any future compliance inquiry about heritage tree condition, that record is the difference between a defensible position and an unverifiable claim.
The post-clearing 3D Digital Twin of the lot — with heritage tree locations and CRZ boundaries overlaid — is delivered to the next contractor in the chain before they mobilize. Pool builders, landscape contractors, and general contractors who arrive with a survey-grade 3D model of the cleared lot make fewer CRZ mistakes than contractors who arrive to a cleared lot with no documentation.
For projects requiring formal Heritage Tree documentation for Austin Development Services Department review — pre-construction tree surveys, CRZ boundary confirmation for permit applications, or as-built documentation for permit closeout — the RTK survey data is the source for those deliverables. No separate arborist survey required for the location and CRZ data.
For lots where lot prep clearing is followed immediately by Land Reclamation — root grubbing, rough grading, rock milling — both scopes can be combined in a single ClearGround mobilization. One site survey, one CRZ mapping, one Digital Twin covering both scopes. The combined mobilization is priced at a discount to the two scopes quoted separately.
