After the property was taken over by the Passaic County Park Commission, the Olmsted Brothers designed the Preakness Valley Park as well as the Dey Mansion garden and grounds. The Olmsted firm did the initial plan for the entire Passaic County Park System in the 1920's and it was built with the assistance of the Works Progress Administration in the 1930's.
