A third major redevelopment project in Tysons Corner has been approved by the Fairfax County Board of Supervisors.

Scotts Run South will add 17 office and residential buildings around the McLean Metro station, on the northeast side of Tysons. The developer also will build a fire station for the county by 2020, to serve growing needs in that section of Tysons as redevelopment occurs.

County supervisors praised the final redevelopment plan, saying the collaboration between county staff and the developer resulted in a high-quality final product.

“Realizing the vision for Tysons requires collaboration,” Board of Supervisors Chairman Sharon Bulova (D) said. “This is a beautiful, beautiful application and something we welcome to Tysons Corner and Fairfax County.”

Supervisors approved a plan for Tysons in 2010 that envisions a pedestrian-friendly urban center. The county anticipates that the area will be home to 100,000 people and 200,000 jobs by 2050.

Scotts Run South incorporates much of the current Westgate office park, one of the first office campuses built in Tysons, and will straddle the Scotts Run Stream Valley Park.

Most of the development will be on 23 acres on the east side of the park. The section can include six office buildings, six apartment buildings and a hotel, according to the land-use plan approved April 9. Most of the buildings will feature shops and restaurants on the street level.

An additional seven acres on the other side of the park will include three high-rise office buildings and another apartment building.

In all, the plan allows for 6.5 million square feet of development, including about 1,400 apartments and 3.5 million square feet of office space. By comparison, the core of Reston Town Center has about 300 apartments and 2.1 million square feet of office space, according to its Web site.

Supervisor John W. Foust (D-Dranesville) said that he initially was apprehensive about such a large redevelopment project on the edge of his district but that ultimately the project won the support of the McLean Citizens Association.

“I think they share my feeling that this is totally consistent with the vision we all approved for Tysons,” Foust said.

As part of the rezoning, developer Cityline Partners agreed to restore the Scotts Run stream and will construct paths, a bridge and other features to allow people to use and enjoy the stream valley park. There also will be five small urban parks and a large civic plaza incorporated into the new development that will include playgrounds and basketball courts. A new public athletic field also will be constructed near the site of the new fire station, on Old Meadow Lane.

Cityline intends to begin construction quickly on one section of the project: two residential buildings with up to 440 apartments between Chain Bridge Road and Anderson Road and a 340,000-square-foot office building in the Mitre office park.

The new buildings will “create an urban skyline” in Tysons, said Lynne Strobel, a Cityline representative.

Scotts Run South is the third major redevelopment plan to be approved around the four new Metro stations in Tysons. There are about a dozen more rezoning plans still going through the land-use process.
