In 2018, Northeastern planned a 55,000-square-foot expansion on a Massachusetts peninsula; Eight years later, the city won the right to take 12 acres by eminent domain to keep it open.

In 2018, Northeastern University announced plans for a major marine science expansion in Nahant, a small, densely built peninsula northeast of Boston. The proposal included up to 55,000 square feet of new research and teaching space on a 12-acre coastal parcel that many residents viewed as one of the city’s last great open spaces. What followed was an eight-year battle over land use, local control and the limits of university growth in a fragile coastal community. In 2026, the Massachusetts Supreme Judicial Court sided with the city and upheld its use of eminent domain to take the 12 acres and preserve it as open space. As reported by the Commonwealth Beacon and Mass Legal Resources, the decision marks a rare victory for a small municipality against a major university in a dispute over the future of its coastline.A small town, a great university.Nahant is one of the smallest cities in Massachusetts in terms of area, a narrow peninsula connected to the mainland by a single causeway. With limited land, strict zoning and a strong sense of local identity, the city has long protected its remaining open spaces, coastal views and residential character.Northeastern University, a large private research institution based in Boston, has been expanding its marine and environmental science programs for years. The university already operates a marine science center in Nahant and in 2018 proposed a significant expansion: up to 55,000 square feet of new buildings on a 12-acre parcel adjacent to its existing facilities. For Northeastern, the site offered direct access to the ocean, space for laboratories and field stations, and the potential to increase its research footprint.The spark of conflictFrom the beginning, the proposal divided the community. Supporters argued that the expansion would bring jobs, research prestige, and educational opportunities, and that Northeastern’s presence was already a key part of Nahant’s identity. Opponents were concerned about increased traffic, pressure on local infrastructure, loss of open space and the precedent of allowing a powerful institution to shape the city’s future. As plans progressed, tensions grew. Public meetings attracted large crowds. Neighborhood groups were formed. Local officials were caught between respecting the university’s ambitions and responding to residents’ concerns about overdevelopment on a small peninsula.The city’s bold decision: expropriationIn a surprising twist, the city of Nahant decided to use eminent domain to take the 12-acre northeast parcel. The goal was not to build anything, but to prevent construction: the city intended to maintain the land as open space, preserving coastal access, views and habitat.Eminent domain, the government’s power to take private property for public use, with compensation, is most commonly associated with roads, utilities, or large infrastructure projects. Using it to block a university’s expansion and preserve open space was unusual and legally risky. Northeastern challenged the take, arguing that the city’s action was inappropriate and that the land should remain available for its planned expansion.Years of legal disputesThe case went through the courts for years. The main questions were whether the city’s stated purpose of protecting open space was a valid “public use” under Massachusetts law, whether the taking was done in good faith or primarily to block Northeastern’s project, and how to weigh the university’s property rights and plans against the city’s vision for its limited land. Lower court rulings produced mixed results, but the central question was the same: Could a small city use eminent domain to stop the expansion of a large university and keep the land undeveloped?State’s highest court rulesIn 2026, the Massachusetts Supreme Judicial Court (SJC) ruled in favor of Nahant, according to reports. The court determined that the city’s use of eminent domain to acquire 12 acres for open space preservation was legal and in accordance with state statutes. The judges emphasized that preserving open space, coastal access and natural resources is a recognized public purpose. The city’s actions were also within its authority, even if the effect was to block Northeastern’s proposed expansion. And the university would receive fair compensation for the land, as required by law, but it had no right to dictate how the city used its eminent domain power.The ruling did not question the value of Northeastern’s research or its presence in Nahant; instead, it focused on the legal scope of the city’s powers and the definition of public use.What the decision means for NahantFor Nahant residents who opposed the expansion, the SJC’s decision was a vindication. The 12-acre parcel can now be permanently protected as open space, with no risk of large-scale development. The city can maintain public access to the coast and views; preserve habitat for birds, marine life and other wildlife; and use the land for low-impact recreational activities, such as hiking, bird watching, and educational programs. For many, it was more than one package. It was about asserting local control in the face of institutional pressure. In a region where universities and developers often dominate, the ruling sent a message that small communities can still define their own future.Campus Expansion and Land Use ImpactsThis ruling sends a loud and clear message to schools like Northeastern: owning property does not mean being able to build on it. Local reactions and legal hurdles can quickly derail massive expansions, particularly in space-starved areas. Expect other cities to take notes. Municipalities are likely to double down on aggressive zoning, open space protections, and even eminent domain to curb heavy-handed institutional growth. If universities want to avoid brutal and costly legal battles, wielding power will no longer be enough. They will have to involve local residents much earlier, approach negotiations in good faith and reach real compromises from day one.A broader conversation about coastal landsThe Nahant dispute also fits into a broader conversation about how coastal lands are used in a warming and developing region. As sea levels rise and storms intensify, preserving open space, wetlands, and natural buffer zones becomes increasingly important for flood protection and ecosystem health. At the same time, demand for waterfront properties for housing, research, recreation and industry continues to grow. The 12-acre parcel in Nahant is small in absolute terms, but symbolic: a test of whether communities can prioritize long-term resilience and public access to the immediate benefits of development. The SJC decision suggests that, at least in Massachusetts, the law may support that choice.What comes next?With the legal battle resolved, attention now turns to the land itself. The city will need to: finalize compensation to Northeastern for the seized property; develop an open space management plan, balancing access, conservation and maintenance; and involve residents in shaping parcel use, trails, signage, habitat protection, and potential educational partnerships with local schools or institutions. For Northeastern, the decision means rethinking its expansion plans on the peninsula. The university can look elsewhere, reduce its ambitions in Nahant or seek collaborative agreements with the city that fit the new reality.The big statement from a small townIn the end, the Nahant case is about power, place and identity. A small coastal city, outmatched in resources and influence, used the law to protect a portion of its landscape from the growth plans of a major university. Eight years after Northeastern first proposed its 55,000-square-foot expansion, the city won the right to keep 12 acres open, ensuring that at least this corner of the peninsula will remain undeveloped for generations to come.
