A tree removal assessment is the written case for taking a tree down. Cities and counties that protect trees often ask for one with a removal permit; HOAs ask for one before they approve; and careful homeowners want one before they spend the money. The case is strongest when it shows the tree, the reason, the evidence, the alternatives that were considered and why they will not do, and what will be planted instead. This template walks exactly that order. Fill it in here and download a PDF without an account, or speak while you walk, and the document writes itself.
Check the rules before you write the reasons
Whether a tree can be removed without a permit depends on where it stands. Many cities protect trees above a certain trunk size, certain native species, street trees, trees in buffers or conservation easements, and named heritage or landmark trees. The rules, the size thresholds and the replacement requirements differ from one city or county to the next, so the form asks you to record which ordinance you checked and how, never to assume one.
Two other questions belong up front. Is the tree on or near a property line, so a neighbor may have a say? And are birds nesting in it? Many places restrict removals during nesting season, and federal law protects most native birds.
Reasons with evidence
A reason is only as good as the evidence behind it. "Dying" should come with what you saw: the percentage of dead crown, the fungal fruiting bodies, the bark coming away. "Damaging the foundation" should come with photos of the cracks and where the roots are. A risk-based reason should say who judged the risk and how — a qualified arborist makes that judgement, often using the TRAQ method — and the form records the rating they gave.
Owner preference is a legitimate reason on private land in many places and is listed honestly as its own option. Where a permit is needed it rarely succeeds on its own, and it is better to say so than to stretch another reason.
Alternatives considered
Reviewers want to see that removal is the last option, not the first. The form lists each alternative — pruning, crown reduction, cabling, root barriers, redesigning the construction, treating the pest, moving the target, or simply keeping the tree and watching it — with whether it would work and why not. A short honest line for each is worth more than a page of argument.
Replacement and the recommendation
Many ordinances require replacement trees or a fee in lieu, and even where they do not, a replacement plan makes a permit easier to approve. Record the species, number, size and location, and the requirement you are meeting. The assessment ends with a recommendation and its reason in plain words, and an urgent removal shows up as a safety finding at the top of the report.
Common questions
Do I need a permit to remove a tree?
It depends on your city or county. Many protect trees above a set trunk diameter, certain species, street trees and heritage trees, and some exempt dead or hazardous trees with documentation. Check the local tree ordinance or call the city forester or planning office before any work.
What should a tree removal justification include?
The tree's identity, size and location; its condition with photos; its protected status under the local ordinance; the reasons for removal with evidence; the alternatives considered and why they were rejected; replacement planting; and a signed recommendation from the arborist.
Who can write a tree removal assessment?
Many cities require an ISA Certified Arborist or a similar credential for permit applications, and some ask for a specific local license. The form records the credentials you type; check what your city asks for.
Can a healthy tree be removed?
Sometimes — for approved construction, utility conflicts, or simply because the owner wants it gone where the law allows. Protected trees usually need a strong reason and replacement planting. The assessment should say plainly when a tree is healthy and why removal is still proposed.
What about birds nesting in the tree?
Most native birds and their active nests are protected under federal law, and many places restrict tree work in nesting season. If you see an active nest, note it, photograph it from a distance, and check the rules before scheduling the removal.
