Sherborn Planning Board Approves Comments Questioning Feasibility of 0 Prospect Street Housing

Planning Board · Meeting of July 21, 2026

Sherborn Planning Board votes to challenge state surplus housing density mandate for 0 Prospect Street. The board voted 5-0 Tuesday to send a formal comment letter to the Select Board raising infrastructure and public health concerns about the state's plan to sell the roughly 7.9-acre parcel for residential development at a minimum density of four units per acre. Co-Chair Stefani Harrison and Co-Chair James T.

Guarino workshopped the draft in real time, with Tom Traynor of the Groundwater Protection Committee warning via Zoom that Title V septic constraints make the density goal "essentially" unachievable without advanced wastewater treatment, and that 32 units would likely require a MassDEP-regulated public water supply — a standard developers have historically circumvented at other Sherborn projects by drilling multiple smaller individual wells. The letter, due to the Select Board by July 22 for the state's August 3 comment deadline, also asks the state to require at least 10 percent affordable units consistent with Sherborn's inclusionary bylaw and flags Prospect Street's status as a designated scenic road under MGL Chapter 40, Section 15C. In a separate action, the board directed the town planner to add a data center prohibition to the zoning bylaw table of uses as part of the ongoing bylaw update, reasoning that Sherborn lacks the infrastructure to support such facilities and that the town should act before any state legislation grants data centers protected status.
