Executive Summary
The Cambridge Planning Board met on June 2, 2026, to conduct public hearings on two significant zoning petitions aimed at strengthening active use requirements along North Massachusetts Avenue and Cambridge Street. The Board also considered a time extension for the HealthPeak PUD (PB410) in the Alewife Quadrangle. While the Board supported the goal of vibrant streetscapes, members expressed concern that the proposed mandates might disincentivize housing production or lead to retail vacancies. The Board voted to transmit detailed comments to the City Council for both petitions, specifically recommending a four-story threshold for active use requirements and greater flexibility for smaller development parcels.

Zoning Petition: North Massachusetts Avenue Active Use Requirements
The Board held a public hearing on a City Council petition to amend Article 17 of the Zoning Ordinance to strengthen active use requirements on North Massachusetts Avenue.
Staff Presentation:
- The petition proposes requiring ground-story active uses for buildings taller than four stories (reduced from the current eight-story threshold) from Cambridge Common to Linear Park.
- It expands the MAS 12A District and amends the MAS 18 District in Porter Square.
- A new Planning Board Special Permit would allow minor modifications to the size and location of active uses, provided the intent is met and floor area is not substantially reduced.
Public Comment Summary:
- Tess Hoffman (Cambridge Redevelopment Authority): Expressed concern regarding a proposed 6-story, 16-unit project at 2326 Mass Ave. She stated, "Additionally, a retail condo is not a desirable feature in a condo building of this size with only 16 owners. It creates a lot of risk for the development as a whole."
- Kevin McGuire (Ascent Development LLC): Highlighted the management challenges of mixing retail with small-scale residential ownership.
- Justin Safe: Argued that unfunded mandates for active use could kill inclusionary housing projects.
- Tom Evans (CRA): Noted that North Mass Ave has a different character than Cambridge Street and requires thoughtful treatment for small parcels.
Board Discussion and Action:
- Members expressed concern that the 4-story threshold might disincentivize the 12-story height targets needed for housing density.
- The Board emphasized that retail requires significant residential density (approximately 2,000 units within a quarter-mile) to be viable.
- Motion: To transmit comments to the City Council stating the Board does not recommend adoption in its current form and suggesting a re-evaluation of the 4-story threshold and protections for small lots.
- Vote: 6-0-0 (Sieniewicz, Cohen, Flynn, Lydecker, Tan, Zern in favor; Macias absent).
Zoning Petition: Cambridge Street Active Use and Formula Business Requirements
The Board reviewed a petition to amend Article 17 regarding Cambridge Street, focusing on active uses and formula business regulations.
Staff Presentation:
- Active Use: Proposes requiring active uses for buildings exceeding three stories.
- Formula Businesses: Establishes a Special Permit requirement for formula businesses in all Cambridge Street districts to regulate aesthetic impact.
- Map Changes: Proposes rezoning a portion of O’Brien Highway back to Business A and incorporating the corner of Gore and 3rd Streets into the business district.
Public Comment Summary:
- Heather Hoffman: Emphasized the importance of the '15-minute city' and providing space for non-chain businesses.
- Jason Alves (East Cambridge Business Association): Stressed that Cambridge Street is unique and successful. He stated, "There is still a need for retail. We should not dismiss that."
- Justin Safe: Opposed the inclusion of Warren Street in the active use mandate due to lack of foot traffic.
Board Discussion and Action:
- The Board expressed support for the formula business permit and the O'Brien Highway map changes.
- Members disagreed with the 3-story threshold for active use, preferring a 4-story threshold to better incentivize housing.
- Motion: To transmit comments to the City Council expressing overall support for the petition's mechanisms but recommending the active use requirement kick in at four stories rather than three.
- Vote: 6-0-0 (Sieniewicz, Cohen, Flynn, Lydecker, Tan, Zern in favor; Macias absent).
General Business: Extension of Time for PB410 (HealthPeak PUD)
The Board considered a request to extend the time for hearing and decision on Planning Board Case PB410, a special permit application for the Alewife Quadrangle.
- Project: HealthPeak PUD.
- Reason for Extension: To allow the applicant sufficient time to complete the final development plan following the positive determination on April 28, 2026.
- New Deadline: October 30, 2026.
Action:
- Motion: To approve the extension of time to October 30, 2026.
