Planning and development in Detroit includes efforts aimed at enhancing Detroit's economy and quality of life. In 1970, the private group "Detroit Renaissance" began to facilitate development in the city, while its successor, Business Leaders for Michigan, has continued to facilitate development into the 21st century. Projects have included new commercial facilities, revitalization of neighborhoods, hospitality infrastructure, and improvements to recreational and public facilities, such as the M-1 light rail project.
In 1970, Henry Ford II conceived of the Renaissance Center as way to help the city retain residents who were moving to the suburbs. The group announced the first phase of construction in 1971. Detroit Mayor Roman Gribbs touted the project as part of "a complete rebuilding from bridge to bridge," referring to the area between the Ambassador Bridge that connected Detroit to Windsor, Ontario and the MacArthur Bridge, which connects the city with Belle Isle Park. He presented architectural renderings of "linked riverfront parks" from Renaissance Center to MacArthur Bridge, like a necklace, for public access.
The first Renaissance Center tower opened on July 1, 1976. Architects initial design for the Renaissance Center focused on creating secure interior spaces, while its design later expanded to connect with the exterior spaces and waterfront through a reconfigured interior, open glass entryways, and a Wintergarden.
Late in 1973, Detroit elected its first African American Mayor, Coleman Young. During his administration major developments completed included, the Renaissance Center, the Joe Louis Arena, the Detroit People Mover, the General Motors Detroit/Hamtramck Assembly Plant, the Detroit Receiving Hospital, the Chrysler Jefferson North Assembly Plant, the Riverfront Condominiums, the Millender Center Apartments, Harbortown, 150 West Jefferson, One Detroit Center and the Fox Theater restoration, among other developments.
