Austin’s tree ordinances are among the strictest in Texas. If you have a construction project—residential or commercial—and trees on the property, you need a qualified arborist involved from the planning stage. Austin Tree Experts provides the full range of tree-related services for construction site compliance: consulting, arborist reports, tree protection implementation, and permitted removals and mitigation plantings.

Consulting for Tree Ordinance Compliance

Our consulting arborists work directly with property owners, developers, architects, and general contractors to navigate tree protection requirements. We prepare tree protection plans, assist with permit applications, and advise on design modifications that reduce impacts to protected trees. Getting an arborist involved early—during the design phase, not after demolition starts—saves time, money, and trees.

Not sure which jurisdiction’s rules apply to your property? The City of Austin, Williamson County, Round Rock, Cedar Park, and other municipalities all have different thresholds and requirements. Use our Jurisdiction Finder tool to look up your property.

Arborist Reports

Most jurisdictions require professional arborist documentation before issuing tree-related permits. We prepare:

• Tree surveys and inventories — Species identification, size measurements, condition assessment, and GPS-located mapping of all trees on the property.
• Tree condition assessments — Detailed evaluation of individual trees for health, structural integrity, and risk.
• Canopy impact assessments — Quantify how much canopy the proposed construction will affect and whether it exceeds allowable thresholds.
• Mitigation plans — When tree removal is unavoidable, we calculate replacement requirements and develop a planting plan that satisfies the permit.

Tree Protection Fences & Monitoring

Once a tree protection plan is approved, we install tree protection fencing around the critical root zones of preserved trees. Fencing keeps construction equipment, material storage, and foot traffic out of the root zone. We monitor the fencing throughout the project to ensure it stays in place and that subcontractors respect the barriers. When the city inspector shows up, your tree protection is compliant and documented.

On-Site Tree Services During Construction

Beyond planning and documentation, we perform hands-on tree work throughout the construction process:

• Mulching — Protecting exposed root zones with mulch to retain moisture and buffer against compaction.
• Airspading — Non-invasive excavation for utility trenching, pier holes, and root zone decompaction near protected trees.
• Fertilizing — Care treatments to support trees stressed by construction activity.
• Pruning — Equipment clearance, damage repair, and permitted canopy reduction.
• Removals — Permitted tree removal with proper documentation and disposal.
• Mitigation plantings — Installing replacement trees to satisfy permit conditions.

Frequently Asked Questions About Construction Site Tree Services

When should I involve an arborist in my construction project?

As early as possible—ideally during the design phase. An arborist can identify protected trees, flag potential conflicts with the proposed design, and recommend modifications that avoid costly permitting issues later. Involving us after construction has started usually means more expensive mitigation and potential code violations.

Can I just remove the trees and pay fines instead?

Technically, but it’s a bad strategy. City of Austin fines for unpermitted tree removal can reach $100,000 per tree for heritage trees, and you’ll still be required to mitigate. Criminal penalties are also possible. The permitting process exists to manage the urban canopy, and the city enforces it. Working with an arborist to navigate the process legally is always the better path.

What is a critical root zone and why does it matter?

The critical root zone (CRZ) is the area around a tree where the majority of structural and feeder roots are concentrated. It’s typically defined as a radius equal to one foot per inch of trunk diameter. Disturbance within the CRZ—digging, grading, compaction, material storage—can damage roots and destabilize the tree. Tree protection plans require that this zone be fenced and protected during construction. Our air-spade allows us to work within the CRZ when necessary without harming roots.

Do you work directly with architects and engineers?

Yes. Our consulting arborists regularly coordinate with design professionals to integrate tree protection into site plans. We provide survey data in formats compatible with CAD and GIS software, and we attend design meetings when needed. Early collaboration produces better outcomes for both the project and the trees.

How long does the tree permit process take?

In the City of Austin, tree permit review typically takes 2 to 4 weeks once a complete application is submitted. The timeline depends on the complexity of the project, the number of trees involved, and whether revisions are required. We handle the entire application process and communicate directly with the city reviewer to keep things moving. Use our Jurisdiction Finder to check which jurisdiction’s rules apply to your property.

What happens if trees are damaged during construction?

If a protected tree is damaged during construction, the city may require remediation—which could include care treatments, soil restoration, and monitoring. In severe cases, the tree may need to be removed and replaced with mitigation plantings. Having an arborist monitoring the site throughout construction helps prevent damage before it happens.
