The Cohasset Zoning Board of Appeals waded into a complex dispute over maritime property boundaries Monday night as neighbors challenged a proposal for a new dock at 45 Joy Place. At the heart of the disagreement is the "colonial method," a century-old surveying technique used to determine where property lines extend into the water. The applicant, Andrew Ashley, submitted revised plans utilizing a 1910 shoreline as a fixed baseline to meet required side setbacks, a move that drew sharp criticism from abutters.

Paul Seaburg of Grady Consulting explained that the method is standard for complex riparian boundaries. The original shoreline is used because it established a predetermined baseline when the lots were originally created before human or natural alterations like erosion or accretion, Seaburg told the board. It’s a fixed reference point. Attorney Jeff Delissi, representing the applicant, argued that because the land is registered, the boundaries are legally fixed by the Land Court. Registered land adjudicates property boundaries, Delissi said. The land court does not register land that moves.

Acting Chair Matt Watkins questioned the logic of using historical markers over modern precision, asking, Do we feel this is the right method or the method that yields the results the applicant is looking for? Board member Lea Fernandez noted her own research into the technique, stating, It makes sense for straight banks. For something similar to a cove, a PI method or another central method would be preferred. We haven't seen that and it doesn't show up on plans dating back to 1910.

Resident Brian Nelson, of 40 Joy Place, urged the board to require a peer review, arguing that modern state law regarding shifting shorelines should take precedence over the applicant’s survey. Massachusetts state law trumps a textbook that talks about general principles, Nelson said. When there's erosion or accretion, these lines move. You can't apply the colonial method to a water boundary from the land plant in 1910... specifically prohibited in the deed. Board member David Morris expressed a desire for more legal clarity on the matter, noting, I always love to go back 100 years to figure things out, and I don't see anything else in front of us. While some easement concerns were raised, Woody Chinnick clarified the board's role: We have no jurisdiction over easements. If there is any kind of dispute about infringing upon an easement, that is a legal matter and not a matter for zoning. Motion Made by W. Chinnick to continue the hearing to January 5, 2026, with a submittal deadline for all parties of December 12, 2025. Motion Passed (4-0-0).

The board also addressed a special permit request for 141 South Main Street, where the owners of a historic 1859 schoolhouse seek to consolidate two front entrances into a single portico. Brendan Sullivan of Grady Consulting explained that the house was originally a two-family structure moved to the site in 1900. When the Asters bought it in the 90s, they wanted to combine the two doors into one grand entrance, Sullivan said. Because the proposed stairs would extend 11.1 feet into the front setback, a permit is required for the existing non-conformity. The board reacted favorably to the aesthetic change, with Fernandez noting, The proposed renovations would be consistent with the neighborhood. When you drive by, you assume it's a two-family. The conversion fits. Motion Made by W. Chinnick to continue the hearing to January 5, 2026, for the purpose of preparing a draft decision. Motion Passed (4-0-0).

In financial business, the board acted on a recommendation from town planning to release several aging escrow accounts. These accounts, which held peer review fees for completed projects, will be closed and the remaining balances returned to the original applicants. Motion Made by W. Chinnick to close the engineering accounts and return the fees held in escrow to the original applicants. Motion Passed (5-0-0).

The board concluded by setting its 2026 meeting calendar. Members confirmed they will maintain a hybrid format to allow for remote participation during the winter months. Motion Made by W. Chinnick to approve the 2026 ZBA meeting schedule. Motion Passed (5-0-0). Earlier in the session, the board also finalized recent records. Motion Made by W. Chinnick to approve the meeting minutes from October 27, 2025. Motion Passed (4-0-1).
