Chapter 1710 - Safety Rest Areas
The Capital Facilities Office has updated guidance on safety rest area design procedures. Guidance is currently found in both the Design Manual (Chapter 1710) and the Roadside Manual. (The Roadside Manual will be phased out over time. Selected material, such as Safety Rest Areas guidance will go to the Design Manual.)
DM Chapter 1710 still contains some geometric design guidance and will remain Chapter 1710, part of Division 17- Roadside Facilities. Our first review, shown below, showed changing it to Chapter 960; that idea has been cancelled.
Current Status 1-26-2012: The second review shown below has:
The chapter number redesignated as 1710 (not 960.)
Added guidance that was to go into the WSDOT Roadside Manual, but since that's being phased out over time, some relevant information has been added to this Design Manual chapter.
Comments from the first review are retained and addressed.

Chapter 1100 - Design Matrix Procedures Design Manual Supplement
The WSDOT Design Matrix Committee has completed their evaluation and revision to the design matrices, associated notes, and some narrative in this chapter. Their work is shown in the first column in the table below. The focus of this effort is to streamline project development processes based on lessons learned from the Nickel and TPA funded projects.
Since the Matrix Committee created and commented on their revisions, we now offer the draft chapter for a brief review period to statewide points of contact. Download the file for review and comment in the second column in this table.
Please respond by 1/31/12.
The goal is to publish this chapter as a Design Manual Supplement in February 2012.

Chapter 1515 - Shared-Use Paths
This new chapter was published in July 2010. Essentially, we moved guidance from the Bicycle chapter and added new guidance about landings.
We plan to take this chapter further, addressing comments received previously and engaging a peer team comprised of WSDOT, local agencies, and policy advocacy organizations. This peer team will revise the chapter and then it will be posted below for review and comment.
Peer Team Status:
Peer Team

Meeting #1 Kick off

Chapter 1620 Impact Attenuator Systems Supplement
A Design Manual Supplement was issued in August 2011. It clarifies use and selection options for low-maintenace attenuators. A third device is now listed as a low-maintenance attenuator, and additional guidance criteria is provided for the selection of low-maintenance attenuators.
This supplement will be incorporated into Design Manual Chapter 1620 as part of the July 2012 manual update. The active supplement is posted online at the Design Manual abstract webpage:
http://www.wsdot.wa.gov/Publications/Manuals/M22-01.htm

The Design Manual Revision Process
Design Manual chapters currently planned for revision are listed in the tables above.
- When a chapter is ready for WSDOT Region and Area review and comment, a "Policy Review Draft" is posted in its respective table and designated points of contact are notified.
- The tables are used by the points of contact to download a chapter for review and comment.
- Tables show the comment review period (usually 4 to 6 weeks).
- Region/Area comments are posted in the tables as they are received.
- After evaluating all comments, WSDOT Design Office posts a file showing the final draft, 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.
View WSDOT Region and Area points of contact list.
List of chapters planned for July 2013 publication:
Chapter 1300 - Intersection Control
- Details forthcoming, after some conclusions on how the Highway Safety Manual will be applied in the Design Manual. (This may be done in 2013, depending on progress with other chapters.)
