The developer of the former Key Bridge Marriott site has released plans to reimagine the area.

Why it matters: The future of the prime piece of land — which sits by the Key Bridge in Rosslyn, overlooking the Potomac — has been a local point of chatter since Marriott vacated the building several years ago.

It was demolished last year, after a fire and series of trespassing incidents.

State of play: The plan is to develop the 5.5-acre site into a community called "Potomac Overlook" that includes five buildings with 1,775 residential units and a 200-room hotel, per a release shared with Axios.

Plus: public green space developed along the Potomac, with seating, art, and bike and walking paths connecting to Gateway Park and the Custis Trail.

What we're watching: TBD on timeline and next steps — Quadrangle Development Corporation, the group leading the project, filed a zoning application with Arlington County last month.
