The Fairfax County Board of Supervisors has approved changes to zoning requirements that allow for higher buildings near Metro stations and in aging commercial areas targeted for redevelopment.
The changes, which the board unanimously approved Tuesday, allow for denser development in 22 areas of the county, including Reston, Seven Corners and the Richmond Highway corridor.

The new zoning guidelines increase the maximum allowable floor-area ratios, or FAR — a measurement used to determine density in buildings that accounts for ground-level retail stores and parking garages.
