Greystar updates Whittington Mills plan; council presses on traffic, parking and school impacts

Greystar Development returned to the municipal council on Tuesday to update staff and neighbors on the continued special‑permit hearing for the proposed Whittington Mills redevelopment at 437 Whittington Street.

Greg Sampson, the applicant’s attorney, opened the presentation with an overview of recent steps: a community meeting, planning‑board site‑plan review, a conservation commission hearing, and submission of updated peer‑review responses and an excerpted fiscal impact analysis. "We have made some good progress," Sampson said, and he noted the submission included updated tax‑revenue and school‑impact numbers.

Aaron Corcoran and the Greystar team described the project program: roughly 390 residential units in ten buildings, about 62% one‑bedroom or junior one‑bedroom units, 23% two‑bedrooms and 15% three‑bedrooms; a 3,800‑square‑foot resident clubhouse; 10,000 square feet of future retail; and site amenities including a walking trail, a community garden and EV charging infrastructure.

Greystar’s traffic engineer, Patrick Dunford (VHB), presented a traffic study covering more than 15 intersections and future conditions to 2031. Dunford said sight‑distance limitations and a history of angled crashes at the Whittington & Bay intersection justified a 4‑way stop, advance warning signage and pruning within the public right‑of‑way; he showed conceptual frontage work to reorganize the roadway, add defined parallel parking (about 14–16 spaces on the project frontage), and narrow travel lanes to reduce vehicle speeds. GPI, the city’s peer reviewer, said the applicant had agreed to most mitigation; a handful of items remained pending or required plan detail.

The applicant reported an estimated $10 million cost to remove and clean up contamination on the site and offered a set of community benefits including a $100,000 community‑funding commitment, a resident welcome program, a community garden and transfer of the retail parcel to a local business at nominal cost. Greystar also proposed phased parking management: build a 1.6 parking ratio (about 624 spaces day 1) and design reserve areas so additional parking can be added if on‑site usage reaches a 95% threshold, with a minimum incremental build of 25 spaces when triggered.

Councilors pressed on several topics: whether the proposed walking trail could be ADA compliant while meeting Wetlands Protection Act constraints, whether school transportation or bus routing would be affected by an estimated 57–72 potential school‑age children, whether on‑street or reserved parking would impair sight lines at driveways, and whether utility upgrades would be completed if MassWorks funding were not awarded. Greystar said it would accommodate school bus access on site if needed, would design the trail to meet conservation constraints and could pay for required water and sewer infrastructure if grants were not available.

Neighbors raised persistent local concerns about parking, safety at the Whittington & Bay intersection and pedestrian crossings; residents urged more on‑site parking and traffic lights rather than temporary stop controls. After public comment the council voted to continue the hearing to April 29 to allow final peer‑review responses and city department recommendations to be filed publicly.

Next steps: applicant to submit detailed plan revisions addressing the outstanding GPI items, add missing peer‑review responses, provide written school‑impact and public‑safety comments from police and fire chiefs, and coordinate on any MassWorks application and utility design.
