LEAVENWORTH, Kan.—The replacement for FCI Leavenworth has achieved LEED Silver certification — a milestone that now leads the narrative of one of the nation’s most significant correctional projects. The designation underscores a commitment to energy efficiency, water conservation, and long‑term resource stewardship, setting a sustainability benchmark for federal correctional facilities nationwide.
The certification is the latest highlight in the $532 million Design‑Build effort underway to replace the aging 1897 prison, once the oldest federal penitentiary in continuous operation. After more than a century of service, the historic facility’s deteriorating infrastructure and outdated systems made modernization impossible, prompting the federal government to pursue a full‑scale replacement designed for contemporary correctional operations and rehabilitation.
Led by Clark Construction in partnership with Elevatus Architecture, the new 200‑acre correctional campus will encompass 23 buildings totaling 630,000 square feet. Elevatus — known nationally for its justice and civic design portfolio — brings a philosophy centered on normalized environments, clear movement patterns, and program‑rich spaces that support rehabilitation and reduce recidivism. Their work on federal and state facilities across the country has helped shape a new generation of secure yet humane correctional environments, principles that are embedded throughout the Leavenworth campus.
The new FCI Leavenworth will house approximately 1,500 inmates across two facilities: a 1,152‑bed medium‑security institution and a 256‑bed minimum‑security camp. Nearly 340 staff members will support operations. Program spaces for education, treatment, job training, and family‑connection initiatives are integrated throughout the campus, reflecting a broader shift in federal corrections toward environments that prepare individuals for successful reentry.
While the project represents a dramatic modernization, it also honors the legacy of the original 1897 facility. The new administration building draws inspiration from the historic prison’s iconic stone façade and dome, and select architectural elements will be incorporated across the campus to preserve tangible links to Leavenworth’s past.
Sustainability is woven into the project’s design and systems. LEED Silver certification recognizes high‑performance mechanical systems, efficient water use strategies, durable materials, and long‑term resource management — all critical for a campus of this scale and operational intensity. The designation also signals a growing federal emphasis on sustainable design within secure environments.
Scheduled for completion this year, the new FCI Leavenworth will replace an aging landmark with a modern, efficient, and program‑focused correctional campus built to serve future generations. The LEED Silver achievement sets the tone for a facility designed not only for security and rehabilitation, but also for environmental responsibility.
