* Estimated Project Cost: $609.5 million.

* Location: Rosslyn. It is a 14.6-acre site defined by Route 50, Route 110 and North Lynn Street. It is immediately north of Arlington National Cemetery and the Marine Corps Memorial. River Place is developed with four residential towers. The site has views of the Washington Monument and the monumental core.

* Details: The site is 11/2 blocks from the Rosslyn Metro station (Orange and Blue lines) and not far from the Arlington Cemetery Station (Blue Line). It is projected that 35 percent to 40 percent of fans arriving to games at the River Place site would come by Metro.

* Parking: Parking at River Place would be provided by a 2,000-car garage partially under the Great Lawn and partially under a potential Arlington County conference center (for premium ticket-holders). On-street parking for about 800 cars exists in the area. Approximately 5,000 existing garage spaces are within a 3/4-mile radius -- these are office garages that would principally be empty during game times. Operational use agreements for event parking are proposed on a building-by-building basis. Additional area improvements are proposed for water and sewer systems, streets (intersections and turning lanes), highways (interchanges and access ramps) and storm drainage.
