Every Tree Has a Permit
Lexington, MA

If you're not doing major construction, the bylaw generally doesn't restrict private property tree removal. But 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: replanting comparable trees or paying $200 per inch of diameter. Trees 24 inches and larger get 4x mitigation. Hazardous trees are exempt from mitigation but still need the permit. We've been through this process dozens of times in Lexington and can handle the entire application for you.

Yes. Properties in Lexington's local historic districts — and there are about 2,000 of them — face review from the Historical Commission in addition to the Tree Warden. Near Battle Green specifically, the scrutiny is highest because of the area's national significance and the Minuteman National Historical Park proximity. Tree work that changes the visible character of the streetscape may require Historical Commission approval. We've worked on multiple properties in the Battle Green area and we know how to present a removal plan that addresses both safety concerns and preservation standards.

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 can add cost in Lexington is the permitting process, the mitigation requirements, and the higher standard of site protection that premium properties require. A straightforward large tree removal in an accessible Lexington yard runs $1,200 to $3,000. If it's in a setback zone during construction, add $200 per inch for mitigation fees. If it's in a historic district with extra approvals, add a few weeks to the timeline. We quote everything upfront — the tree work price and the expected permit costs — so there are no surprises.

That's 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 the fines. The new amendments now require a tree protection plan during development and mandate replanting in front of newly developed properties. If you're buying a property for demolition and rebuild, plan the tree work into your project timeline from day one. We work with builders and homeowners on these projects regularly.

Almost certainly yes. American elms that survived Dutch elm disease are rare and genuinely valuable — both ecologically and to your property value. Lexington has a handful of survivors, and the town makes a point of protecting them. If your elm is showing signs of stress — yellowing, wilting, bark loss — it could be a late-arriving Dutch elm infection, but it could also be elm leaf beetle or a treatable issue. Call us before you assume it's terminal. We'll assess it honestly.

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.
