Boynton Yards

Boynton Yards. A major mixed-use redevelopment district in the City of Somerville, Massachusetts, transforming a former industrial corridor into a hub for life sciences, technology, and residential living. Located adjacent to the Union Square neighborhood, the project is a cornerstone of the city's SomerVision comprehensive plan and represents one of the largest private investments in Somerville history. Its development is closely tied to the extension of the MBTA Green Line and is managed by master developer US2.

History

The area's industrial roots date to the 19th century, when it served manufacturing and warehousing needs for the growing Boston metropolis. For much of the 20th century, it was dominated by facilities like the A. G. Spalding baseball factory and other light industrial uses, contributing to Somerville's identity as an industrial inner-ring suburb. The decline of traditional manufacturing in the latter half of the century left the district underutilized, characterized by vacant lots and aging infrastructure. Planning for its transformation accelerated in the 2000s, catalyzed by the planned Green Line Extension and the city's adoption of the SomerVision plan, which designated the corridor for dense, transit-oriented growth. Key land assembly and zoning changes were approved by the Somerville City Council in the 2010s, paving the way for large-scale redevelopment.

Development and planning

The project is being executed under a master plan overseen by developer US2, which secured development rights following a selection process by the Somerville Redevelopment Authority. The phased plan, governed by a detailed Planned Urban Development agreement, envisions approximately 2.3 million square feet of new construction across multiple city blocks. Major components include significant life science and office space, market-rate and affordable housing units, retail, and public open space. The development is structured around a series of new streets and pedestrian pathways intended to better integrate the area with surrounding neighborhoods like Union Square and East Somerville. Financing involves complex public-private partnerships, with contributions for affordable housing and infrastructure.

Architecture and design

The architectural approach blends contemporary, large-scale commercial structures with adaptive reuse of historic industrial buildings, creating a varied streetscape. Lead architecture firms such as Sasaki Associates, Utile, and Anmahian Winton Architects have contributed master planning and building designs. The aesthetic often incorporates brick and metal paneling, nodding to the site's industrial past while meeting modern sustainability and performance standards for biotechnology tenants. Design priorities include achieving LEED certification standards, creating activated ground-floor uses, and ensuring strong pedestrian connections. A central public plaza and several smaller parks are integral to the plan, designed by landscape architecture teams to provide communal space.

Transportation and access

The district's viability is fundamentally linked to major transit investments, primarily the MBTA Green Line Extension, which added the nearby Union Square station. This provides direct rail access to Lechmere, North Station, and Downtown Boston. Multiple MBTA bus routes also serve the area, including connections to Harvard Square and Sullivan Square. The development plan mandates robust bicycle infrastructure, including dedicated lanes and extensive Bluebikes station access, aligning with Somerville's Vision Zero policies. Vehicular access is provided from Washington Street and Somerville Avenue, with a focus on managing congestion through parking maximums and trip reduction programs.

Economic impact and future prospects

The project is positioned to significantly bolster the regional economy, particularly within the Greater Boston life sciences cluster, by providing new space for companies adjacent to major research institutions like MIT and Tufts University. It is expected to generate thousands of permanent jobs and substantial new tax revenue for the City of Somerville. Future phases will add more residential units, helping to address the regional housing shortage. Long-term prospects are tied to the continued growth of the Kendall Square innovation ecosystem and the overall demand for transit-accessible lab and office space. The project's success is viewed as a critical test case for transit-oriented development in Massachusetts post-Green Line Extension.
