Wetlands Ordinance Amendments
Shift to NWI mapping and larger buffers affects private property usability, land value, and environmental protection.
The Planning Board is considering amendments that would replace soil-based wetland mapping with NWI data and introduce larger buffers up to 50 feet for significant wetlands. The change is intended to improve wetland identification but has raised concerns about reduced usable land and property impacts. Work remains in the refinement stage with a GIS analysis of affected parcels ordered.
The Wetlands Ordinance Amendments issue originated in the Planning Board's ongoing review of zoning changes during its May 14, 2026 meeting, when staff outlined a proposal for prime wetlands identification paired with a 50-foot buffer.
At that meeting the board agreed to continue work on the wetlands proposal alongside other amendments, setting the stage for a dedicated public discussion the following month.
On June 18, 2026 the board examined replacing NRCS soil mapping with National Wetlands Inventory data and introduced a three-tier classification system consisting of Significant Wetlands (50-foot buffer), Important Wetlands over 5,000 square feet (25-foot buffer), and smaller jurisdictional wetlands (no buffer).
Board members noted that NWI layers were already visible in the town's GIS and directed staff to run an analysis counting affected properties while refining ordinance definitions.
Public comments at the June meeting highlighted concerns that the shift and expanded buffers would reduce usable land and affect property values, while also questioning map accuracy and the priority given to environmental features such as salamander habitat.
Residents requested that any adopted map be appended to the ordinance and suggested large printed versions be available at voting locations to improve accessibility.
The board's position, as recorded in the controversial-issues section, signaled movement toward more rigorous mapping and larger buffers while attempting to limit impact by exempting very small wetlands from buffers.
No final vote has occurred; the process remains at the refinement and impact-analysis stage.
The planning staff will run a GIS analysis to count how many properties will be affected by the proposed overlay changes and refine the ordinance definitions.
