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

• Placement of physical measures in the roadway to decrease vehicle operating speeds (e.g. speed humps, speed tables and pavement markings). 

The road must:

• Be in the state system of highways owned and maintained by VDOT.
• Be classified as a local, residential collector or residential arterial road.
• Function as a residential street.
• Have a speed limit of 25 miles per hour (MPH).
• Have a traffic volume between 500-6,000 vehicles in a 24-hour period.
• Have an 85th percentile speed of at least 35 MPH in at least one direction.

Qualification Phase

1. The community sends its request to the District Supervisor, who forwards it to FCDOT.*
2. FCDOT performs a study to determine if the road meets the qualification criteria.
3. The community forms a task force to work with FCDOT on plan development.

Plan Development Phase

1. The task force works with FCDOT and VDOT to develop a traffic calming plan.
2. The task force obtains concurrence from property owners directly adjacent to proposed measures.
3. FCDOT determines the ballot area based on the task force’s proposed plan.
4. The task force and FCDOT hold a community informational meeting.  Notification is provided to all residents in the ballot area.
5. The task force determines whether to conduct a vote via ballot or revise the plan.

Plan Approval and Installation Phase

1. A vote via ballot is held.  The task force provides a ballot to all properties in the primary use area identified by FCDOT.
   • To pass, greater than 50% of the issued ballots must vote in favor of the plan.
2. FCDOT requests endorsement of the traffic calming plan from the Board of Supervisors.
3. The Board of Supervisors resolution is sent to VDOT for review.
4. FCDOT sends traffic calming plan to Department of Public Works and Environmental Services for installation.

*_{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.

• Access restrictions or route modifications.

• 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.

Qualification Phase

1. Request: The community sends its request to the Board of Supervisor’s (BOS) office:

• 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/CA, then a request shall be made in the form of a petition by either 10 residences or 10% of residences along the street (whichever is less).

If the BOS office agrees to pursue cut-through traffic measures, they request the Fairfax County Department of Transportation (FCDOT) to conduct a study to determine the eligibility of the street and identify appropriate traffic control measures.

2. Conduct study: FCDOT conducts a study to determine the eligibility of the street proposed for cut-through measures and potential cut-through measures to address the issue. The study addresses the following components:

• Verifying road type and speed limit
• Performing a study to ascertain the volume of cut-through traffic.
• Identifying a reasonable alternate route
• Selecting cut-through traffic measures
• Consulting with local officials
• Preparing study documentation including primary use area

VDOT confirms interim study findings and conclusions and may assist with the study.

3. Concurrence with study and recommendations: VDOT approves the study results and recommendations for proposed cut-through traffic measures and their relative impacts.

4. Determination of community support: The locality presents the results of the study and the recommended cut-through traffic measures at a community/public meeting. Afterwards, the locality conducts a ballot to determine if the required level of community support for implementation of the proposed cut-through measures is met.

• At least 2/3 of the occupied residences on the streets identified in the “primary use area” must support the measures.

5. Public meeting: The locality holds a public meeting to provide for public input on the study recommendations. Thirty days prior to the public meeting, a notice of the public meeting is made to the community.

6. BOS endorsement: After appropriate consideration of the public comments received, the BOS submits a resolution to VDOT indicating their endorsement for the implementation of cut-through measures.

7. Implementation: FCDOT and VDOT coordinate the installation of the approved measures.

8. Review: After installation, FCDOT and VDOT begin evaluating the effect of the installed measures on the road network.

• $200 Additional Fine for Speeding signs underneath speed limit signs.

• The road must be a local road, a collector road, or a minor arterial.
• The road must have a speed limit of 35 mph or less.
• The road must have at least 6oo vehicles per day.
• The 85th percentile speed of vehicles is at least 10 mph over the speed limit in at least one direction.

1. The community sends its request to the District Supervisor, who forwards it to FCDOT.*
2. FCDOT conducts a traffic count and speed survey of the road.
3. FCDOT determines whether the road meets the qualification criteria.
4. If the road meets the qualification criteria, the District Supervisor confirms community support for $200 Additional Fine for Speeding signs.
5. The Board of Supervisors endorses the installation of $200 Additional Fine for Speeding signs.
6. FCDOT sends request to VDOT for the installation of the signs.

• The restriction must be enforceable.

1. The community sends its request to the District Supervisor, who forwards it to FCDOT.*
2. FCDOT conducts a preliminary analysis of the road to determine if the prohibition would be enforceable and if a reasonable alternate route exists.
3. If the road meets the preliminary criteria, the Board of Supervisors conducts a public hearing to approve a resolution for the through truck restriction.
4. The resolution is forwarded to VDOT.
5. VDOT conducts a comprehensive engineering review of the road.
6. VDOT publishes a notice of proposed restriction for additional public comment.
