Traffic calming is the placement of devices in or along the roadway with the intent of reducing vehicle operating speeds to the posted speed limit.

• Traffic Calming General Operating Procedures

PROCEDURE:

Qualification Phase

1. The community sends its request to the District Supervisor, who forwards it to FCDOT.*

*_{A request shall be made to the District Supervisor either by the Homeowners Association (HOA) or Civic Association (CA) for the neighborhood. If there is no HOA or CA, then a request shall be made by either 10 residences or 10% of residences along the street (whichever is less). For neighborhoods where there is an association, the District Supervisor may also choose to accept a request made by 10 residences or 10% of residences along the street (whichever is less).}

Cut-through mitigation attempts to decrease non-local through traffic in residential areas.

MEASURES:

• Access restrictions or route modifications.

QUALIFICATION CRITERIA:

• The road must have a speed limit of 25 miles per hour.
• The road must be a local residential street.  Local residential streets provide direct access to a residential area and are intended only to provide mobility within that area.
• A minimum of 150 cut-through trips in one hour in one direction and 40% or more of the total one hour, single direction volume must be cut-through traffic.
• A reasonable alternate route must exist.

Note: Under certain conditions, residential collector streets may be considered for cut-through mitigation and will be limited to traffic calming measures. No traffic diversion measures will be considered.

PROCEDURE:

Qualification Phase

1. The community sends its request to the District Supervisor, who forwards it to FCDOT.*
2. FCDOT determines if the road type and speed limit are acceptable.
3. FCDOT performs a study to ascertain the volume of cut-through traffic. 
4. If the road meets the qualification criteria, FCDOT issues a primary use area map & petitions.
5. The community forms a task force to gather signatures to establish at least 75% support for a cut-through study in the primary use area.
6. The Board of Supervisors approves a resolution requesting VDOT to accept the candidate road into the cut-through mitigation program.

Plan Development Phase

1. The task force works with FCDOT and VDOT to develop a cut-through mitigation plan.
2. VDOT studies and evaluates the plan.
3. FCDOT and VDOT recommend a preferred alternative if one exists.
4. The task force determines whether to continue.

Plan Approval and Installation Phase

1. FCDOT determines the notification area based on the task force’s proposed plan.
2. The task force, FCDOT, and VDOT hold a community informational meeting.  Invitations are sent to all residents in the notification area.
3. The task force determines whether to continue.
4. A vote via ballot is held.  The task force provides a ballot to all residences in the primary use area identified by FCDOT.

5. VDOT and Fairfax County conduct a joint public hearing for the cut-through mitigation plan.
6. The Board of Supervisors approves a resolution requesting VDOT to accept the candidate road into the cut-through mitigation program.
7. Based on the engineering evaluation, the results of the ballot, and public comment, VDOT determines whether to implement the cut-through mitigation plan.
8. FCDOT and VDOT coordinate the installation of the approved measures.
9. After installation, FCDOT and VDOT begin evaluating the effect of the installed measures on the road network.
