Tree Advisory Board Meeting - 2026-09-18

Detailed briefing

Tree Advisory Board Meeting — September 18, 2026 ATTENDEES: Roll call named Dana Mulder, Carol Winnard, Kathy Marshall and Bob Thoma; the board stated it had a quorum. Chris and Tina participated in discussion, and a Conservation District representative discussed invasive species. - The board approved the prior meeting minutes. Before approval, members agreed that a confusing sentence about retaining the order of a prior agenda could be removed or reworded. - A Conservation District representative reported knotweed at several city locations, including Deer Park, a park near the ball fields, Kiwanis Park and an Ann Street right-of-way. Some growth near Ann Street may extend onto adjacent private property. The city representative said to proceed with treatment on city property once the site form is provided; treatment on private property would require landowner permission. - Initial knotweed treatment was estimated at up to about $600 for roughly a half day of work, with follow-up likely needed over multiple years. The contractor said treatment could begin before frost and would use a foliar spray. The discussion included posting spray signs, notifying nearby residents where appropriate, and publishing public information about knotweed. - Members discussed a potential joint effort involving the Tree Board, Parks Board and Harbor Commission to address harborfront parks as a unit. Participants supported collaboration in principle, but said the Harbor Commission had not yet acted and City Council would need to determine priorities and how such work fits with other city projects. - For 2026 street trees, the board discussed pausing proposed trees on the steep State Street hill while observing snow-removal conditions during winter. Members discussed possible fall planting at the Shea House/Blackbird area, Lake and Ann streets, and Indiantown Park or Second Street. DPW utility review and final species/location confirmation remain necessary. - The board discussed updating the vegetation-management plan to address invasive species, utility conflicts, root-management options, trimming practices, special requests, replacement after tree removal, unauthorized removal of city trees, and tree protection during construction. School rain-garden work remains pending follow-up with the superintendent. Worth watching: - Whether knotweed treatment is scheduled promptly and whether adjacent Ann Street property owners grant access. - DPW's utility review and final confirmation of fall street-tree locations and species. - Whether City Council advances a harborfront collaboration and sets priorities for carryover park projects. Upcoming: The board expects follow-up on the school rain garden in one to two weeks; student representative applications were said to be due near the end of September. Why it matters: The discussion links near-term invasive control and fall tree planting with longer-term decisions about park stewardship, infrastructure conflicts and the city's urban canopy.
