Protecting Trees Through Better Planning.

Construction and development can substantially affect tree health and structural stability. Early arboricultural involvement helps identify constraints, evaluate impacts, and develop practical preservation strategies.

Preservation & Development Services

Planning for retention

Tree preservation plans, tree protection zones, critical root zone evaluations, and tree inventories for development.

Evaluating proposed impacts

Construction impact assessments, trenching and excavation assessments, and municipal permit documentation.

Supporting the project team

Construction monitoring and consulting, with an agreed scope suited to the project and its tree-related constraints.

Our Approach

Start before decisions are finalized

CRITICAL works with property owners, contractors, architects, and project teams to evaluate trees early in planning. We consider condition, site constraints, proposed work, and realistic preservation opportunities.

Assess preservation feasibility

Retention is not simply a line on a plan. Tree condition, species, rooting environment, proposed disturbance, and available protection measures inform whether preservation is practical.

Construction Impacts to Consider

Root disturbance and excavation

Trenching and excavation can affect water uptake and structural support. Critical root zone evaluations help identify potential conflicts before work proceeds.

Grading and soil compaction

Changes in grade and compacted soil can alter drainage, aeration, and the rooting environment, affecting tree health beyond the visible construction area.

Construction access

Access routes, equipment movement, and material storage can expose retained trees to disturbance. Protection recommendations consider how the site will actually be used.

Practical protection

Recommendations are developed for the assignment, not as generic engineering plans. Tree survival and regulatory outcomes cannot be guaranteed.

Make the Next Decision With Confidence.

Whether you’re evaluating a concerning tree, planning construction, navigating municipal requirements, or managing a larger tree population, independent expertise can help establish a clear path forward.
