Tree Removal Permit

A permit required by many jurisdictions before removing or significantly pruning protected trees, intended to preserve the urban tree canopy and the environmental benefits trees provide.

What is a Tree Removal Permit?

A tree removal permit is an authorization required by many cities and counties before removing, relocating, or significantly pruning trees that meet certain size, species, or location criteria. Tree protection ordinances are designed to preserve the urban tree canopy, which provides environmental benefits including shade, air quality improvement, stormwater interception, habitat, and aesthetic value.

Which Trees Are Protected

Protection criteria vary by jurisdiction but commonly include: trees above a specified trunk diameter (often 6-12 inches), trees of designated heritage or landmark species, trees on public property or within the public right-of-way, trees in designated open space or environmental areas, and sometimes all trees on commercial development sites. Native species often receive higher protection than non-native species.

The Permit Process

Tree removal permit applications typically require an arborist report documenting the size, species, health, and condition of trees proposed for removal, along with justification for the removal. The reviewing authority evaluates whether removal is necessary for the proposed development and whether alternatives exist. Conditions of approval commonly include replacement tree planting — often at ratios of 2:1 or higher.

Trees and Development Planning

Tree protection requirements can significantly affect site design by constraining where buildings, utilities, and grading can be placed. Protected root zones often extend well beyond the tree canopy. Identifying protected trees early in the design process allows the project team to design around them or plan for the permit and mitigation requirements associated with removal.
