Traffic Impact Analysis


To All Applicants for Zoning Changes Including Rezoning, Special Exception and Special Permit and Amendments to These Land Use Categories  

The following procedural changes for submission of Traffic Impact Analyses (TIA) have been made by the Fairfax County Department of Transportation in cooperation with the Virginia Department of Transportation. These were reviewed and approved by the Fairfax County Board of Supervisors on August 3, 2009. To summarize, TIAs will be submitted for review by the County and State at the time of submittal of a zoning case to the Department of Planning & Zoning. Practice prior to this procedural change required acceptance of the zoning application for review by the Department of Planning & Zoning prior to transmittal of the TIA. The text below outlines the context of the change.

Procedural Changes

Beginning October 1, 2009, all Traffic Impact Analyses (TIA) required under State Chapter 527 regulations for rezoning applications (includes rezoning, proffer condition amendments, special exception applications and amendments, and special permit applications and amendments) shall be submitted to the Fairfax County Department of Transportation (FCDOT) concurrent with the initial filing of the application with the Fairfax County Department of Planning and Zoning (DPZ). 

At that time the TIA will be forwarded to the Virginia Department of Transportation (VDOT) to be reviewed for compliance with regulatory submission requirements associated with State Chapter 527 regulations.  Upon a favorable determination by DPZ that the rezoning application satisfies the minimum submission requirements of the Fairfax County Zoning Ordinance, the application will be distributed for review however scheduling of public hearing dates will not occur until FCDOT and DPZ staffs are notified that the submitted TIA meets the applicable regulatory submission requirements. 

This change in procedure allows an earlier opportunity to review the traffic data anticipated with the pending rezoning application and identify potential deficiencies in the submitted TIA.  The goal of this procedural change is to resolve any regulatory deficiencies in the TIA early in the process so that when public hearing dates are established for the rezoning application the focus can shift to addressing transportation needs identified during the application review.

For general information or questions regarding the processing of TIAs please contact the FCDOT Site Analysis Section at 703-877-5600, TTY: 711.
