Weston Planning Board Signals HYM Senior Housing Proposal Needs Fall Town Meeting Timeline

WESTON -- February 25, 2026, Weston Planning Board opens first formal public hearing on a 215-unit age-restricted senior housing project at 300 Wellesley Street, signaling the proposal will not reach the May town meeting ballot. HYM Investment Group LLC, the applicant, presented updated setbacks, 100 feet minimum lot-line and 125 feet from the single-family district, and extended its 10 percent affordability pledge to include assisted-living units. Abutters including Chris Cavanaugh of 1 Colonial Way and Ken Morrison of 301 Wellesley Street raised objections to scale, traffic, tree removal, and affordable housing reliability, with Morrison citing a Brookline project in which HYM-affiliated investors replaced 18 required affordable units with a cash payment. Chair Leslie Glynn said the board cannot craft a revised bylaw in time for the March 24 warrant close, noting a failed vote would bar resubmission for two years. The board voted 5-0 to continue the hearing to March 4 and separately approved, also 5-0, a redesigned accessory structure at 56 Ridgeway Road with a flat roof and a side-yard tennis court positioned to preserve a 53-inch basswood tree.
