The Future of the Dey Mansion Garden Restoration Project

The Department of Cultural & Historic Affairs (DCHA) creates and maintains a flourishing cultural landscape throughout Passaic County. As the designated proponent for the County’s heritage and the agent for arts and history programming, the DCHA is responsible for developing, promoting, and implementing an extensive public programs calendar and heritage tourism campaign to encourage public awareness and visitation to the County’s various historic sites.

Included in these sites are the Dey Mansion Washington’s Headquarters, Hamilton House Museum, Lambert Tower, Lambert Castle, Passaic County Arts Center at the John W. Rea House, Westervelt-Vanderhoef House, Passaic County Court House, Passaic County Court House Annex, Goffle Brook Park, and Garret Mountain Reservation. Through this ongoing endeavor, the DCHA maintains these sites for Passaic County residents and visitors to enjoy today, and will ensure that these sites are preserved for the benefit of future generations.

The Friends of Dey Mansion, Inc. proposes a new project entitled Dey Mansion Garden Restoration Phase II at the Dey Mansion Washington’s Headquarters. The project includes adding a new garden, that mimics 18th century design and style for the use in interpretive programming and hands-on workshops. New flower beds, pathways, and site furnishings are included in the design. A full concept plan showing the proposed changes and a preliminary cost estimate can be found at: and
