Every Tree Has a Permit
Lexington, MA

If you are not doing major construction, the bylaw generally does not restrict private property tree removal. The dead maple in your backyard can come down without anyone at town hall caring. The bylaw kicks in during construction or demolition: any tree 8 inches or larger in diameter within the setback zones — 30 feet from the front property line, 15 feet from the sides and rear — is protected. Removal requires a Tree Warden permit and a mitigation plan, which is either replanting comparable trees or paying $200 per inch of diameter into the town tree fund. Trees 24 inches and larger trigger 4x mitigation, which is exactly as cheerful as it sounds. Hazardous trees are exempt from mitigation but still need the permit. We have filed enough Lexington permits to handle the whole application for you.

Yes. Properties in Lexington's local historic districts — and there are about 2,000 of them — get a second pair of eyes from the Historical Commission alongside the Tree Warden. Near Battle Green specifically, the scrutiny is highest because the area has national significance and the Minuteman National Historical Park is next door. Tree work that changes the visible streetscape may require Historical Commission approval. We have worked on multiple properties in this area and we know how to present a removal plan that satisfies both the safety case and the preservation case. If the tree predates the country, we can wait three more weeks for paperwork.

The tree itself costs what it costs — a 60-foot red oak in Lexington is the same amount of work as one in Billerica. What adds money in Lexington is the permitting process, the mitigation requirements, and the higher standard of site protection that premium properties demand. A straightforward large removal in an accessible Lexington yard runs $1,200 to $3,000. If the tree is in a setback during construction, add $200 per inch in mitigation. If it is in a historic district with extra approvals, add a few weeks to the timeline. We quote the tree work and the expected permit costs upfront, with no 'starting at' pricing — you get the real number before we touch a saw.

That is exactly why Lexington updated the Tree Bylaw in 2024. When a house gets torn down for new construction, the trees in the setback zones become protected under the bylaw. Developers used to clear everything and pay nominal fines; the town watched the canopy disappear for fifteen years and decided enough was enough. The new amendments require a tree protection plan during development and mandate replanting in front of newly developed properties. If you are buying a Lexington property to demolish and rebuild, plan the tree work into the project timeline from day one — and call us for a pre-closing walkthrough before the offer goes in. A free walkthrough can save you from a $40,000 surprise three months into the project.

Almost certainly yes. American elms that dodged Dutch elm disease are rare and genuinely valuable, both ecologically and to your property value. Lexington has a handful of survivors and the town protects them on purpose. If your elm is showing yellowing, wilting, or bark loss, it could be a late-arriving Dutch elm infection — but it could also be elm leaf beetle, drought stress, or something else treatable. Call before you assume it is terminal. We will walk the tree honestly. If pruning fixes it, that is what we recommend. If removal is the answer, you will know why.

Yes, but those areas trigger Conservation Commission review under MGL Chapter 131, Section 40. The 100-foot buffer zone applies to Vine Brook, the Shawsheen River headwaters, and associated wetlands. The Conservation Commission in Lexington is one of the most active in the state — they take wetland protection seriously. We file the Request for Determination of Applicability or the Notice of Intent, provide the tree assessment, and attend the hearing. Hazardous trees near waterways usually get approved, but the commission may require erosion controls or replanting as conditions.

Under Lexington's Tree Bylaw, when a protected tree is removed during major construction, you owe mitigation — either replant comparable trees or pay into the town's tree fund at $200 per inch of trunk diameter (DBH), plus a $20 per inch permit fee. A 20-inch oak removal means $4,400 in fees. Trees 24 inches and larger get 4x mitigation: a 30-inch tree could cost $24,000 in replanting value or fees. The key word is 'protected' — this only applies to trees in setback zones during construction. Routine removal on your property without construction doesn't trigger it. And hazardous trees are exempt from mitigation regardless. We'll tell you at the estimate exactly what applies.

We have, and it's some of the most careful work we do. The oaks along Battle Road and near the Minuteman visitor areas are historically significant — some were standing when the British marched through in 1775. Pruning heritage trees means deadwood removal only, clean cuts to ISA standards, no topping, no over-thinning, and minimal ground disturbance. We've pruned oaks in this area that had 4-foot diameter trunks and canopies spanning 60 feet. This isn't a job for a crew that's in a rush.
