Milton lawmaker says Mattapan trolley misclassified under MBTA Communities Act; withdraws amendment after talks

Senator William J. Driscoll of Norfolk and Plymouth told the Senate that Milton is being “subjected to an inaccurate and undeniable misclassification” under implementation of the MBTA Communities Act and withdrew an amendment after further discussions with state housing officials.

Driscoll charged that Milton is not trying to “carve itself out” of the statute but instead seeks a fair, consistent application of the law that governs which communities must zone for either 25 percent, 15 percent, or 10 percent of existing housing stock under transit‑oriented zoning requirements.

Why it matters: classification determines the locally required housing‑production targets and can materially affect local zoning, assessments and development obligations. Milton — which borders parts of Boston served by the Mattapan High‑Speed Line — faces a higher 25 percent zoning requirement if the town is treated as a “rapid‑transit” community rather than an adjacent community that could adopt a 10 percent plan.

On the floor, Driscoll walked senators through modal and capacity differences he said justify reclassification. He stated that a single Mattapan trolley car “holds a 30 people” capacity and that the vehicle dates to the 1940s; by comparison, he said a Red Line car holds 67 passengers, the Green Line car 212, and a commuter rail car 79. Driscoll pointed to MBTA operational distinctions: the Mattapan line and Green Line are administered under separate light‑rail leadership and the MBTA in 2024 appointed a director specifically for light rail.

Driscoll also noted municipal financial and service comparisons: he said Milton’s FY25 MBTA community assessment is about $2.1 million, while neighboring Quincy — which operates four Red Line stations and multiple modalities — had a stated assessment of about $2.5 million. Driscoll argued that Milton already has a locally drafted 10 percent plan that was submitted to the state housing and land use board (HLC) and was under HLC vetting; he urged regulators to allow Milton to anchor to commuter‑rail proximity or to be considered an adjacent community rather than a rapid‑transit community.

“I want to show you as well today that there is a history going back decades where Milton has contributed in an outsized way to the MBTA communities,” Driscoll said. “This is about fairness and it's about consistency.”

After presenting maps, station proximity and capacity figures, Driscoll said he was withdrawing the amendment to allow more conversation among municipal leaders, HLC and state officials. “I'm withdrawing this amendment today because further discussions are needed with my colleagues in this room, my local colleagues in government, and Milton with HLC and the administration,” he said.

What happened: Driscoll withdrew his amendment after outlining the town’s case and noting that the Milton planning board had a revised local plan under HLC review and expected a town meeting vote in June. He asked colleagues to consider Milton’s circumstances before a final classification is imposed by regulation.

What to watch: whether HLC accepts Milton’s 10 percent plan as an appropriate route for compliance and whether the MBTA Communities Act implementation guidance is revised or clarified to treat the Mattapan High‑Speed Line as an intermediate modality, as Driscoll urged. If Milton remains classified at a higher tier, the town would face larger mandatory zoning obligations and potentially higher assessment expectations in future cycles.
