The owners of White Flint Mall submitted a sketch to the county last month, previewing what they plan to do with the large parcel.
In November, Lerner Enterprises and Tower Companies announced their intent to with residential, commercial and office space around a plaza.
The preliminary drawings show a mixed-use development, with most of the tallest buildings on the northwestern part of the property and a 2.1-acre public open space in the middle.
The designers were inspired by the Luxembourg Gardens in Paris, the Washington Post reported, and they plan to install recreation areas, a fountain and outdoor seating.
The Planning Department has received the sketch plan and is yet to schedule any hearings on the proposal, department spokeswoman Valerie Berton said.
