Wellesley is the only Norfolk County town we cover, and the drive from our Billerica yard via Route 128 lands us in Wellesley Square in roughly forty minutes. We are not the local crew. We are the technical crew that shows up when the local crews are booked three weeks deep and the project has a Section XVIE deadline.
The town's tree bylaw — Section XVIE of the Zoning Bylaw, passed at Town Meeting in 2011 — is one of the stricter ones in eastern Massachusetts. It protects trees of 10 inches DBH or greater in the Tree Yard of residential properties, triggered by demolition or major construction. The Tree Bank mitigation schedule runs $150 per DBH inch on the first 20 inches, $250 per inch from 21 through 75, and $400 per inch on 76 and above. A 50-inch heritage oak removed without on-site replanting costs $10,500 in mitigation alone. Most local renovations involve us pricing the bylaw line by line before the demolition permit goes in.
The heritage canopy is the other reason we get the call. Wellesley has more mature American and European beech per square mile than most MetroWest towns. Cliff Estates, the Hunnewell-adjacent properties, College Heights — old town, old trees, and now a new problem in beech leaf disease that is hitting the canopy faster than most homeowners realised it would. We assess. We treat where we can. We remove and replant where we cannot.
The Charles River frontage and the brook system — Fuller Brook, Rosemary Brook, Boulder Brook, Waban Brook — put a large fraction of Wellesley parcels inside Riverfront Area or wetland-buffer jurisdiction. That layer is handled by the Conservation Commission, and we file what they need.
Wellesley's canopy is anchored by heritage red oaks (Quercus rubra), white oaks (Quercus alba), and large sugar maples (Acer saccharum) in the older neighborhoods around Cliff Estates and Wellesley Hills. Mature American beech (Fagus grandifolia) and European beech (Fagus sylvatica) — including some of the regions's most impressive copper beeches — are concentrated around the Hunnewell estate, the College, and the older estate streets, and most are now showing signs of beech leaf disease. Sycamores (Platanus occidentalis) line several of the town's older residential corridors. Silver maples (Acer saccharinum), eastern cottonwoods, and white pines dominate the Charles River frontage and the brook corridors — all species with weak wood prone to storm failure on saturated root plates. Ash trees are dying off rapidly from emerald ash borer.
