Tree Preservation for Development Projects

Designed, Specified, and Defended by Industry Experts   

Capitol Tree Preservation provides consulting, design, and construction solutions that preserve trees during development—while reducing risk, meeting regulatory requirements, and improving long-term outcomes.

With over 30 years of experience, our team works with municipalities, engineers, and developers to ensure tree preservation is not just planned—but successfully executed.  

The Problem We Solve:   Tree preservation routinely fails—not in theory, but in execution

  1. Trees decline or die after construction
  2. Protection plans are ignored or poorly enforced
  3. Root systems are damaged during grading and utility work
  4. Soil conditions are not designed to support long-term survival
  5. Projects face delays due to regulatory non-compliance

Most projects approach tree preservation as a checkbox.

We approach it as a technical discipline integrated into site design and construction.

 

Our Approach:  A Systematic Approach to Tree Preservation

We integrate arboriculture, engineering, and construction practices into a cohesive process:

1. Tree Inventory & Feasibility Analysis

We evaluate existing trees to determine realistic preservation potential based on species, condition, and site constraints.

2. Design Integration

We work with engineers and planners to align grading, utilities, and layout with tree preservation goals.

3. Protection & Soil Systems

We specify and implement proven systems—including structural soil solutions and root protection methodologies—to support long-term viability.

4. Construction Oversight

We provide on-site arborist guidance to ensure plans are followed and adapted as conditions change.

5. Post-Construction Viability

We focus on outcomes—ensuring preserved trees survive and perform after project completion.
