Public Hearing: Case PB410 - HealthPeak PUD Development Proposal
- Applicant: HealthPeakOP LLC
- Location: Alewife Quadrangle
- Proposal Summary: A Planned Unit Development (PUD) special permit application to develop 42 acres into a mixed-use district including residential, retail, office, and lab buildings, a municipal service facility site, and a pedestrian/bicycle bridge over the MBTA railroad.
- Key Project Statistics:
- Land Area: 42 acres.
- Use Mix: 60% commercial, 40% residential.
- Residential: Over 400 units in the initial 'R2' building; total residential area includes buildings R1, R2, and R6.
- Open Space: 14.6 acres of new publicly beneficial open space (14 times the existing amount).
- Parking: 4,578 total spaces (3,288 net new) utilizing shared parking strategies.
- Sustainability: All-electric (excluding backup power), LEED and Passive House benchmarking, and a projected 4-5 degree reduction in peak summer temperatures via heat island mitigation.
- Key Discussion Points:
- The Bridge: The pedestrian/bicycle bridge is a critical infrastructure piece. The applicant is currently in 'purgatory' with the MBTA regarding the exact siting due to potential commuter rail electrification needs.
- Phasing: The bridge is currently slated for completion in Phase 2 (at 75% commercial build-out), though Board members expressed a desire to see it moved to Phase 1.
- Retail: Allison Williams (OfPlace) emphasized 'neighborhood uses' over traditional retail to ensure a self-sustaining 7-day-a-week environment.
- Public Comment Summary:
- Ann Tennis (71 Griswold St): Expressed concern over traffic on Concord Ave and the height of the P3 parking garage. 'This is the City's opportunity to create a new residential, small business and commercial community. Let's work together.'
- Joseph Maglita (160 Cambridge Park Dr): Raised concerns regarding construction and operational noise. 'It's gone from annoyance to nuisance to hazard.'
- Doug Brown (35 Standish St): Supported the DPW site but urged for the bridge to be delivered earlier than 15 years. 'Waiting 15 years to start construction would be a disservice to the community.'
- Tim Blauer (80 Fawcett St): Concerned about the 85-foot height of parking garage P3 blocking sunlight.
- Board Action: The Board made a preliminary determination that the proposal generally conforms with the PUD district and Alewife Overlay zoning.
- Vote Outcome: 7-0-0.
- In Favor: Ted Cohen, Mary Lydecker, Diego Macias, Ashley Tan, Carolyn Zern, Dan Anderson, Mary Flynn.
- Against: None.
- Abstentions: None.
Public Hearing: 79 Sherman Street - DPW Salt Shed
- Applicant: Department of Public Works (DPW)
- Proposal: Replacement of the existing salt storage shed and site improvements within Danahy Park (Open Space zoning district).
- Project Details:
- Capacity: Increasing storage from ~1,200 tons to 2,000 tons.
- Structure: Replacing a 1990-era Cambrough arch with a modern shed of the same height.
- Facilities: Adding a bathroom, brine equipment room, and a small break room for operators.
- Board Discussion: Dan Anderson questioned the site selection. John Nardone (DPW) explained that the city's inventory is limited and the new Mooney Street site (1.2 acres) is too small for salt storage.
- Action 1 (Report to City Clerk): The Board voted to send a report to the City Clerk recommending the project.
- Vote: 6-0-0 (Cohen, Lydecker, Macias, Tan, Zern, Flynn).
- Action 2 (Recommendation to BZA): The Board voted to transmit a positive recommendation to the Board of Zoning Appeal for required variances.
