Canton Planning Board approves Green Lane/Green Street subdivision over abutters’ access objections

The Canton Planning Board voted to approve a subdivision for land at 70–74 Green Lane and 90 Green Street after a lengthy hearing in which neighbors and an abutters’ attorney raised questions about legal access, stormwater maintenance and potential archaeological impacts.

The board approved waivers to local subdivision rules and the final definitive subdivision vote following the close of the public hearing. The clerk moved to approve the plan and, after a second, the motion carried on a recorded vote of 3 in favor and 2 opposed.

Why it matters: Neighbors said the project depends on private easements and long‑term homeowner‑association maintenance of stormwater infrastructure and a private road, which they warned could shift costs and risk to existing residents. The site lies within an Area of Critical Environmental Concern (ACEC), and the Canton Historical Commission requested an independent archaeological survey before any approval, a request that residents reiterated during public comment.

Public comments and legal access dispute An attorney speaking for abutters, appearing early in the hearing, raised a central legal objection: he told the board that ‘‘90 Green Street . . . does not have title rights to access Green Lane’’ and urged the panel that the record contains no deed or easement showing legal access. He argued claims of easement by prescription would require a court determination and said, ‘‘this is a significant issue. It cannot be ignored.’’ (public comment by attorney for the Coulter family).

Several residents emphasized public‑safety and maintenance concerns. Jonathan, who identified himself as a resident at 75 Green Lane, said he lives at the lowest point on Green Lane and warned that ‘‘any issues with water is gonna roll right into, my property’’ unless a clear, enforceable long‑term maintenance plan is in place. Courtney Wason (72 Green Street) and others said recently circulated exhibit plans appeared to propose widening a private right of way and installing a new water main, changes they said would affect property ownership lines and require clearer documentation.

Environmental and historic preservation concerns Jessica Rockland, citing a letter from the Canton Historical Commission, asked whether an independent archaeological survey had been commissioned; the commission had recommended a professional survey because the development could pose a ‘‘clear risk of direct and irreversible impact to potentially significant archaeological resources.’’ Nick Pundit and other residents noted that parts of the site lie inside an ACEC and urged stricter environmental review, raising questions about porous asphalt long‑term performance near wetlands.

Applicant response and plan changes Applicant counsel Suzanne Matthews and project engineer Eric Dias told the board the applicant had met with town reviewers and the conservation commission and had obtained an order of conditions from the conservation commission. Dias described three substantive plan updates for the planning board: a proposed emergency connection (Road B) providing a second means of egress to avoid a dead‑end over the town’s threshold; a negotiated easement across 94 Green Street to loop the water main back to Green Street so the unnamed private way would not be excavated; and replacing about 120 linear feet of roadway at the subdivision entrance with porous asphalt, together with an operations and maintenance plan to be recorded at the registry of deeds.

On the emergency access compromise, Dias said the team ‘‘will remove the gate, and we will make it passable, for emergency vehicle in that location and we will just employ signage on both sides that say emergency access only. Do not enter.’’ He said the applicant had also designed the stormwater systems conservatively and that the Zoning Board of Appeals would revisit the aquifer protection and stormwater review after the planning and conservation reviews were complete.

Board deliberations, conditions and waivers After the hearing was closed, staff summarized draft conditions that would accompany an approval: limits on buildable lots as drawn on the plans, surety or covenant requirements before an approval takes effect, recorded deed restrictions and 35‑foot do‑not‑disturb buffers on specified lots, required HOA documents to fund long‑term stormwater and road maintenance and an annual budget for those obligations, coordination with the fire department on turning radii and emergency access, and periodic inspections tied to recorded conditions.

The board voted on five requested waivers from subdivision regulations (roadway cross section, slope near an intersection, conventional street lighting, roof runoff infiltration method, and water main extension requirements). Staff described the waivers and their implications; each waiver passed on a recorded vote of 4–1.

Final outcome and procedural next steps The Planning Board then voted on the definitive subdivision plan. The clerk moved to approve the 70–74 Green Lane and 90 Green Street subdivision; after a second the motion carried on a recorded vote of 3 in favor and 2 opposed and the board announced conditions to be recorded with the decision. The board also approved minutes from March 18 (one abstention) and adjourned; its next meeting is April 15.

What remains open - Legal access: abutters’ counsel maintained there is no recorded easement for 90 Green Street to use Green Lane and said the question of prescriptive rights likely requires a court decision; the board accepted the legal debate as material but proceeded with conditions and waivers. - Archaeology: the applicant said no archaeological survey has been commissioned yet and that surveys may be required as part of later permit approvals; residents asked the planning board to ensure the Historical Commission’s request is resolved before construction activity. - Maintenance and enforcement: the board’s approval includes requirements for a recorded operations & maintenance plan and conditions meant to bind a future homeowners association; residents remain concerned about long‑term enforcement and costs.

The board’s decision and the associated decision documents, conditions and recorded operations & maintenance plan will be available through the Planning Department and the registry of deeds as required by the approval.
