Traffic Control Plans

City, county, and state regulatory agencies frequently require a traffic control plan (TCP) to be submitted and approved before working in a public right-of-way. D&H Flagging has created over 8500 TCPs that cover all contractor requirements, from a simple sidewalk closure to entire freeway system closures and detours. Additionally, we guarantee that our TCPs will be approved by your permit reviewer with no extra cost to you.

  • Typical turn-around time is 2-3 business days (dependent on current work load – please call and verify with our Planning department)

  • Rush TCP requests may be accepted with the addition of rush fees

  • Additional fees may be applied if revisions or additional phases are needed due to changes from your original work zone requirements.


Important: D&H Flagging does not file for permits. We simply provide the TCPs you are required to have when submitting your permits.

D&H currently offers TCP creation services for Oregon and Washington (excluding Seattle – SDOT).  Many reviewing agencies ask for two weeks to fully review a permit with attached traffic control plans. We recommend that you submit your TCP request to D&H at least three weeks before your planned start of work date. This will allow adequate time for your permit and TCPs to be created, submitted, reviewed, and approved.

Special note for PBOT and City of Portland:

As a reminder, PBOT granted D&H Flagging an exemption from using their PBOT Basemap for the creation of traffic control plans. All D&H site-specific traffic control plans are drawn in-house and will not appear on the PBOT Basemap; however, our planning department utilizes the PBOT Basemap to create workspace diagrams.

What’s the difference between a site-specific traffic control plan and a workspace diagram? A site-specific traffic control plan is a detailed drawing of the road, work zone dimensions, all traffic control devices, and instructions. A workspace diagram is a simple drawing of the work zone dimensions only. The workspace diagram will be matched with the appropriate standard plan from the PBOT manual. Both site-specific traffic control plans and workspace diagrams are submitted to PBOT for review and approval.

PBOT has provided a flow chart that outlines the criteria related to both options:

Our planners will be able to help you determine which form of plan is appropriate for your project, given PBOT’s latest requirements.

Please call or email our Planning team with your job information and site map, and one of our planners will walk you through the process.
