The tables below show the chapters in the current revision cycle. The column marked "Current Status" shows where a chapter is in the process.

  • When a chapter is ready for region/area review, it is posted in the first column.
  • Comments will be posted in the second column.
  • The third column is used to post the document, with all comments merged and responded to.
  • The fourth column presents the chapter as an FYI posting to view the outcome.
  • After approvals, the chapter may be downloaded from the right-hand column called "Available for Use." This service allows designers to begin using the new material before it is officially published.

Chapter 1030 Delineation

The HQ Traffic Office has revised the current chapter, updating policy on guide post reflectors at intersections. The Standard Plan M-40.30-00 will be revised to coincide with this change. Other text changes as apparent in tracked mode.

This chapter is one of the last ones still in old format. When published it will be in the current DM format.

The Design Manual Revision Process
Design Manual chapters currently planned for revision are listed in the tables above.

  • When a draft chapter is ready for WSDOT Region and Area review and comment, a "Review Draft" is posted in its respective table and designated points of contact are notified.
  • The points of contact then download the chapter file and distribute to people in their region/area.
  • Tables show the comment review period (usually 4 weeks).
  • Points of contact collect comments and send back to HQ Design Office. Those comment files are posted in the tables as they are received.
  • After evaluating all comments, the Design Office posts a file showing the final draft for approval, with all comments and the HQ Design Office's response to them. Not all comments are used, but all are considered.

When a chapter has "final approval," it will be available for use prior to publication. See the link in the right-hand column of each table as chapters are approved.

Region "Points of Contact" (POCs)
WSDOT regions have identified specific people to act as POCs to coordinate a unified region response to draft policy changes.

  • POCs coordinate with people in their region to review/comment on draft policy.
  • POCs send their region's comments back to HQ in one document.
