Adopted by Council: 10/30/2014
Effective: 10/30/2014


To adopt an official policy for the appropriate and consistent application of traffic calming measures.


This policy, upon adoption by the Town Council, shall be applicable on town maintained streets until such time that the policy statement is altered, modified, or rescinded by the Town Council. This is a Town of Cary Policy Statement . As such, Town Council has full authority to waive any and all obligations under this Policy at its discretion.


Traffic calming measures are only applicable in residential neighborhoods, where speeding vehicles and/or cut-through traffic are the primary concerns and traditional police enforcement is not feasible. The following policy and procedure are meant to ensure the measures are used as intended and receive the support of the community and Town of Cary staff. 

  1. Streets must be residential in nature. Traffic Calming devices shall not be placed on streets identified as Thoroughfares or Collector Streets as shown on the Cary Comprehensive Transportation Plan.

2.   The Engineer will consult with the Fire Department and the Department’s approved list of streets before proceeding with a plan.

3.   Should the request meet the Fire Department’s criteria for approval of traffic calming devices, the Town of Cary Department of Transportation and Facilities will mail each affected homeowner a notice of how to access an informational report on the Town’s web page. This report, along with other informational items, will provide each resident with ample information to make a decision whether to support or reject the request for traffic calming devices. 

4.   A minimum of two weeks later, the Engineer will develop a petition list based on an "area of influence" defined by the Engineer on a case-by-case basis. The Town desires to have neighborhood acceptance levels at 70% or greater but may approve devices at its discretion. Petitions must be returned to the Town no more than six months after receipt. If requested, the Town may issue a new petition after six months at its discretion. Should the Town approve devices, the fee is 25% of the total construction costs. All checks should be made payable to the "Town of Cary."

5.   For requests received from neighborhoods with Homeowner’s Associations, feedback from the Association is desired. The Town may, however, approve of installation without Homeowner’s Association input. 

6.   Upon final review of all comments and paperwork, a report will be submitted to Town Council for review and approval.

7.   The Engineer will identify the location of each device in the neighborhood to provide residents with a minimum of two additional weeks to comment before construction begins. Minor revisions in the location of the devices may be allowed before construction begins. 

8.   The Engineer shall make every effort to have the devices installed as soon as schedules permit. Each device shall be clearly marked with pavement markings and warning signs posted at neighborhood entrance points within 24 hours of installation. Temporary markings may be allowed for an interim period. 

Note: Item 9 shall be retroactive and applicable for any neighborhood that has traffic calming devices in place as of the date of adoption of this Policy.

9.   Once approved by Town Council, requestors may request to have the devices removed after an adequate review and analysis period of no less than one year after installation. These requests for removal shall be required to follow the process defined in items 4-6 above. There are no fees associated with the removal of devices.
