Traffic Control Plans

A Traffic Control Plan is required for all work performed within the public right-of-way!

The basic objective of each traffic control plan (TCP) is to permit the contractor to work within the public right of way efficiently and effectively, while maintaining a safe, uniform flow of traffic. Both construction work and the public must be given equal consideration when developing a traffic control plan. In addition, when considering the public, attention must be given to all aspects of travel through the work zone: i.e., vehicular, bicycle, and pedestrian.

Fee Schedule:

Lane Closure - $52 per sheet

Road Closure - $104 per road (upon approval from the Director of Public Works)

Checklist & Guidelines:

It is the goal of the Traffic Control Plan (TCP) to achieve balance between providing a safe working environment within the right-of-way, and providing motorists, bicyclists, and pedestrians with a safe and efficient means to travel through the work area.

Following the submittal of traffic control plans, all plans shall be reviewed within five (5) working days. A traffic control plan that does not include all of the required elements listed below will be found incomplete, and returned for revision and re-submittal.

The following checklist is provided to assist Developers and Contractors in establishing uniformity in the development of TCP's. This checklist should be used as a guide to ensure that all of the basic elements are covered, and will help speed-up the plan review process.
