Portland Tree Consulting Preservation Plans
Tree preservation plans are used by property owners, contractors, and others involved with land division and development. In these cases, various municipal codes regulate how many trees must be retained and how many can be removed. These codes are complex, are updated frequently, and are different in every jurisdiction. We help our clients navigate these regulations and comply with the law.

Tree Codes Are Far-reaching
In the City of Portland, tree codes apply to anyone seeking to subdivide a property or develop it. This includes individuals, businesses, construction companies, and architects involved with the project. By develop, we mean building a structure or subdivision, apartment building, or an ADU. Each of these triggers one or more City Code requirements relating to tree protection measures during construction.

Requirements Vary
In the City of Portland a land division, property boundary line adjustment or the like will require a professional arborist to develop a tree preservation plan. All trees 6" in diameter and larger must be accounted for. There are various parameters based on the number of trees that are 20" diameter and larger, and requirements regarding the total inches of tree diameter on the property.
A Demolition Permit and a Development Permit both trigger additional obligations relating to street tree density and overall tree canopy area, based on the square footage of the property. In addition to 6" trees, there are obligations based on 12" trees, 20" trees, with special requirements for trees 36" and larger.

Portland Tree Consulting Arborist Reports
Arborist reports are technical documents used by property owners when applying to remove trees from their land.
Arborist reports are technical documents used by property owners when applying to remove trees from their land.
Homeowners and businesses might wish to remove treesfor a variety of reasons, including:
The trees are dead, dying, or have a disease that could spread to other trees.
The tree has characteristics that make it a hazard to the public. For example, it might have weak trunks or branches or shallow root structures that can’t support the tree during a wind or ice storm.
The tree is an invasive species and removing it would benefit the local ecosystem.
The tree is interfering with plans for approved construction on the property, or is growing in such a way that it is causing harm to existing structures or property amenities.

Confusing and Complicated Code with Certified Arborist
Depending on the property’s location, one or more municipal codes might apply, potentially limiting a property owner’s options for tree removal. Different requirements apply to different types and ages of trees. Permit applications must be filed that thoroughly explain the need for the tree removal. Proceeding without approval is ill-advised: Often, the penalties for noncompliance are steep, and can lead to costly delays in construction and development plans.
