Tenmile River Master Plan

Tenmile River Master Plan


Located along a New York City commuter rail line and spanning 500 acres, the Tenmile River Master Plan transforms a decommissioned state psychiatric campus into a vibrant new Hudson Valley community. The master plan is rooted in a design and placemaking strategy that bridges the powerful economies of metropolitan areas with rural communities in need of investment.

With a focus on introducing job-generating uses, a diversity of housing types, educational opportunities, and transit-level densities, the master plan blurs the rural and urban divide through a deep integration of architecture and landscape. Over 300-acres of woodlands, waterfront areas and stunning views of the river valley are preserved and improved for the benefit of residents and the surrounding community. Existing buildings on the site will also be preserved and repurposed with new programs. Extensive art and cultural programming will further activate the site and contribute to its unique sense of place and community.
