Nearly 1,100 new apartment units could be coming to Pentagon City as part of a major planned development of the 37-acre RiverHouse apartment complex.
RiverHouse owner Vornado presented the initial development plans to largely skeptical members of the Arlington Ridge Civic Association last night.
The plans call for 934 new market rate apartment units, to be added to the existing 1,670 units on the site across three buildings, which date back to the 1950s and 60s. Vornado is also proposing a 150 unit, stand-alone affordable apartment building, to be developed with a nonprofit affordable housing partner.
The new market rate units will be built across three buildings, each about seven stories tall — half the height of the existing buildings — to preserve the views of condominium residents on Arlington Ridge.
The first two buildings are to be built on what is currently a surface parking lot across from the Pentagon Row courtyard. Between the buildings will run a pedestrian corridor that leads up to the ridge, with 30,000 square feet of ground floor retail space.
The surface parking will be replaced with a large underground garage. RiverHouse aims to reduce its overall parking ratio from just over one spot per unit to 0.85 spots per unit, as currently only about 70 percent of its parking spots are filled at night. With a total of 2,754 units, RiverHouse would have 2,340 parking space.
The third building will be built on what is now a pool and detached fitness center behind two of the buildings. In place of the current amenities, the new building would have a larger, improved fitness center plus a large, new outdoor pool, for use by residents of all three buildings.
Grace Hopper Park, located on the RiverHouse grounds, would remain untouched. Beside it, in front of the southernmost RiverHouse building on S. Joyce Street and across from county softball fields, Vornado is proposing the 150-unit building, affordable for those making up to 60 percent of area median income.
