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

Simplified ICA with step-by-step process. Clarified “roundabout-first” guidance. Added specific performance measures related to off-peak hours. Added displaced left-turn intersection type. Added guidance to Pedestrian Considerations. Relocated and simplified Operational Considerations; moved some under procedures.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. 

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.
