Everyone from children and conservationists to the governor of Michigan gathered under a tent on Detroit’s waterfront Wednesday to hear details of a $100 million plan to redevelop much of the downtown waterfront into a public oasis that will connect to hiking trails across the state.

The Ralph C. Wilson Jr. Foundation today celebrated what would have been the 100th birthday of its founder by donating $100 million to redevelop Detroit’s West Riverfront Park, a 22-acre site located west of Joe Louis arena at the intersection of Mexicantown, Corktown and Southwest Detroit.

Wilson, a businessman and venture capitalist who grew up in the Grosse Pointe area, grew to prominence in Buffalo, NY where he was the founding owner of the Buffalo Bills pro football team.

The foundation also is donating $100 million to develop LaSalle Park in Buffalo. Both parks will be called the Ralph C. Wilson Centennial Park.

The $100 million for Detroit’s riverfront development will be divided as follows:

$40 million grant to the Detroit Riverfront Conservancy

$10 million to the Community Foundation for Southeast Michigan to maintain the park

$40 million in capital support for regional trails in southeast Michigan

$10 million for long-term sustainability of the trails

The tiny model on display Wednesday along with renderings showed a riverfront with a network of walkways, benches and a small peninsula that juts out into the Detroit River.
