Karis Lustig, director of the GPW in Needham and a member of the Envision Needham Committee, told the Planning Board on Oct. 21 that the committee is reworking a long-running downtown reconstruction project for Great Plain Avenue and does not expect to start public engagement until December at the earliest.

Lustig said the project—originally conceived as five phases over 30 years—was rebooted after public feedback in 2021 that urged more pedestrian- and bike-friendly design. The committee has narrowed three concept approaches: a more complete “road diet,” a near‑existing condition option and a compromise option, and has expanded the corridor under study from Linden to Warren.

The update came as members and others pressed for clarity on near-term impacts on local businesses, parking, deliveries and stormwater. "There is no single solution that will provide everything that everybody wants in the downtown," Lustig said, describing the committee’s work to illustrate trade-offs so the town can gather constructive public feedback.

Why it matters: the downtown scope includes sections of Great Plain Avenue that are due for pavement rehabilitation in the next few years and infrastructure failures were exposed during flooding on Aug. 8, 2023. Lustig said the Chestnut/Chapel/Great Plain intersection was under about a foot and a half of water during that event and some downtown businesses were flooded; improving drainage is a minimum requirement for any final design.

Key details and debate
- Pilot and sequencing: the committee discussed temporary pilot treatments (proof‑of‑concept installations using temporary materials) to test designs before committing to permanent hardscape. That idea raised concern among businesses about immediacy and disruption. Lustig said pilots can be executed faster but are unfamiliar in suburban settings.

- Business outreach and parking: Adam (Planning Board member) urged stronger outreach to landlords and retail tenants, saying many businesses face economic stress from higher interest rates, material costs and lingering pandemic impacts. He encouraged reducing formal parking requirements and streamlining waiver processes to lower barriers for new development.

- Traffic diversion and data: Natasha (Planning Board member) asked how traffic would be diverted if lane reductions occur. Lustig and committee members said consultants are using modern mobility data (cell‑phone movement datasets) and travel‑demand modeling (VISSIM was named) to show that a significant share of vehicles during peak hours are through‑traffic—not trips that start or end in downtown Needham. "What they actually found out was during the peak period that the majority of the traffic coming through our downtown is through traffic," Lustig said; the consultants plan to use that information to evaluate road‑diet options.

- Loading and deliveries: board members raised repeated concerns about box trucks and deliveries that currently double‑park in the downtown. Staff said the project team surveyed businesses about delivery timing and vehicle sizes and that dedicated loading zones, curb‑management rules and short‑duration parking (for quick takeout) are being considered as part of all three alternatives.

- Signals and bottlenecks: board members were briefed on a connected but separate effort to improve signal timing in the corridor. The town has state funding through a bottleneck‑reduction grant for signal improvements and is negotiating with the vendor to install camera‑based adaptive signal controls. Town staff said, "Our goal is to have it done by the end of the year." The adaptive signal work is intended to operate independently of the Envision concept design but the two efforts address the same corridor performance issues.

Next steps and public engagement
Lustig said the committee will refine the three concept plans and prepare materials to show trade‑offs to the public; public engagement is not expected before December. The committee will continue coordination with planning staff, zoning work happening in parallel (including MBTA‑related planning and possible downtown rezoning), and transportation and DPW projects such as TIP‑funded improvements on Highland Avenue.

The committee and board members asked for more and clearer visualizations (including flow animations and multi‑day parking/loading counts) and suggested inviting builders and local brokers to review assumptions in fiscal and zoning studies. The committee is also tracking drainage and sidewalk width needs for the scissor‑gate/quiet‑zone locations in the corridor.

Ending: The Envision Needham committee is continuing concept development and data work over the coming months; staff will return with refined visuals and a public engagement plan once the team has firm concept comparisons and modeling results.
