Residents packed P.S. 133 Tuesday night to find out what developers have in store for the site of the Key Food Supermarket in Park Slope.

Avery Hall Investments has proposed to redesign the space into rental apartments, with a quarter of those apartments being affordable housing. The plan also calls for retail space.

The land falls under an urban renewal plan, and any changes must be approved by the community board and the city.

Some neighbors want to make sure the developers put a full-service supermarket in that space.

New York City Comptroller Scott M. Stringer said in a statement: "I stand with the Park Slope community in calling for a full-service, affordable supermarket at the site of the Fifth Avenue Key Foods. Any plans for new retail space at this location must include a grocery store that provides good jobs and allows middle-class New Yorkers to put healthy and affordable meals on the table. I am going to work with the Fifth Avenue Committee to make sure that this community's voice is heard and that there continues to be affordable grocery options in Park Slope."
