The Board of Supervisors authorized the Zoning Ordinance amendment for Tysons on March 23, 2010, to be concurrent with the Comprehensive Plan amendment. This facilitated the county being able to receive and process development proposals under the newly adopted Plan.
The new zoning district for Tysons is referred to as the PTC District; Planned Tysons Corner Urban District. Additionally, the Board adopted the Board of Supervisors' Guidelines for Trip Generation Analysis for rezoning applications to the PTC District.
With the Zoning Ordinance Modernization project (zMOD) adopted by the Board on March 23, 2021, images were added to illustrate the character of the PTC District.
