Riverhead moves ahead with eminent domain for Science Center site

Riverhead has taken its fight over the Long Island Science Center site on East Main Street to the next level, voting to begin an eminent-domain process that could allow the town to seize the property for public use.

The Town Board approved the move 3-1, with one abstention, a split that showed clear support for pushing ahead but no unanimous agreement on using one of government’s most powerful land-use tools. The vote was more than a procedural step. It marked a sharp escalation in a long-running dispute over who should control the future of a prominent downtown parcel and what kind of development Riverhead wants to anchor on East Main Street.

Eminent domain is politically charged because it can override private ownership in the name of a public purpose. In this case, the town is signaling that it believes the site is important enough to justify a formal condemnation process, with the possibility of taking the property if the legal steps are completed. That raises immediate questions about how far Riverhead is willing to go, what public objective it believes the land would serve, and how much taxpayers may ultimately bear if the process moves into a legal fight.

The stakes extend beyond the science center itself. East Main Street is part of Riverhead’s downtown core, where every land-use decision carries ripple effects for redevelopment, traffic, neighboring businesses and the town’s long-term identity. A condemnation action can affect adjacent property values and shape expectations for future projects, especially in a corridor where local leaders have tried to balance redevelopment with community needs.

If the town succeeds, it would give Riverhead direct control over a site that sits at the center of a broader argument about downtown priorities. Supporters of the move are betting that public ownership or public-directed use will better serve the area than leaving the parcel in private hands. Opponents are likely to see a dangerous precedent, especially if the town ends up spending significant public money to settle a dispute that could have lasting consequences for Main Street planning.

For Riverhead families, the issue is not just about one building on East Main Street. It is about whether downtown change will be driven by private owners, public planners or a costly clash between the two. The board’s vote made clear that the town is prepared to press that question much further.
