Details of the plan are spelled out in a community benefits ordinance presentation from a Wednesday evening meeting. Additional information about the development effort was not immediately available.

The 2.3-acre, L-shaped parking lot was acquired in a $12.2 million online auction in 2015 as part of a joint venture. In addition to the apartments and grocery store, there would be other retail uses plus 484 parking spaces in a parking deck.

It would sit immediately east of The Platform's 231-unit apartment development called The Boulevard at Third Avenue and Grand Boulevard.

Major regional and national grocers have made inroads into Detroit in recent years, including the Whole Foods store in Midtown and three Meijer Inc. locations already built or in development at Eight Mile Road and Woodward Avenue, in northwest Detroit and on East Jefferson Avenue. Gordon Food Service opened its first grocery store in Detroit earlier this month.

Under Proposal B that passed in November 2016, community benefits agreements are required for developments of $75 million or more and receiving $1 million or more in public incentives or on property with a cumulative market value of $1 million or more that was sold or transferred to a developer.

The plans were revealed as part of the CBO presentation for The Platform's Cass & York project.

The transformational brownfield incentives were first approved three months ago for four Dan Gilbert projects totaling $2.14 billion; the incentive package totaled $618.1 million. The enacting legislation, signed in 2017, states that projects must total at least $500 million in Detroit to qualify for such incentives. There is a five-step approval process to receive them, starting first with the Detroit Brownfield Redevelopment Authority and ending with the Michigan Strategic Fund.

The Platform, which was founded in 2016, has undertaken several projects along Grand Boulevard, including the renovation and redevelopment of the Fisher Building, which it owns with New York City-based HFZ Capital Partners and New York City-based Rheal Capital Management; the Lakeshore building at 7300 Woodward Ave.; and a building on East Grand Boulevard known for the colorful paint-spill mural on its western wall.

The company has also targeted the Fitzgerald, Islandview and other neighborhoods, near Eastern Market, plus northwest Detroit and most recently, just south of Midtown.

It has hundreds of millions of dollars in projects in varying stages of completion.
