Chapter 120 - Planning
Currently seeking region and area input on value of this information in the Design Manual. Asking the same question about Chapter 130 Project Development Sequence.

Read Comments received
Comments reflect that:

  • information is out of date, such as Federal program narrative,
  • much information presented may not be of beneift to users of the Design Manual
  • Enviromental Procedures Manual covers some of this subject matter too
  • Websites might be the better location for this planning information
  • Raise question of overall intent of the Design Manaul: narrow design focus, versus all precontruction phases.

Any changes to these Design Manual chapters, including shifting some material to other chapters, will likely not make the July 2013 revision package. Plan on working this out for publication July 2014.

This chapter is a result of combining guidance from existing chapters 220 and 230, both of which will be retired.

There is 4 pages of content providing designers an overview of the environmental topic with emphasis on project coordination with environmental staff. Reference links are updated to the Environmental Procedures Manual (EPM) as well as online Enviromental resources for permitting and other areas of work.

Chapter 1620 - Impact Attenuator Systems
This revision was to include addition of new products. That is looking unlikely for this revision cycle. Consult the Qualified Products Listing (QPL) for additional attenuator devices not identifed in the current Design Manual.

 
Chapter 1260 - Sight Distance
This chapter was revised to align more with AASHTO and MUTCD standards regarding object height and passing sight distance. Some of the revisions are as follows:

  • Removed the definitions (they will be moved into a glossary)
  • Revised the evaluation of 6-in object height to 2.0-ft (updated applicable  text, charts, graphs, and formulae accordingly
  • Added object/eye height criteria in each section title
  • Inserted color photos and exhibits throughout the text
  • Revised values of passing sight distance to align with the 2011 Green Book and MUTCD

Parking Area Design

Concept:
Improve parking area guidance for users of the Design Manual.

Questions for Regions and Areas: how can the Design Manual best be improved to provide more guidance to designers on parking area design?

Examples: Would you want that to be a new chapter in the 1700s, add more material to Chapter 1430, or propose another idea?

Current WSDOT Guidance on parking design includes:

  • Roadside Manual Chapter 630 - Parking Area Design. This chapter is planned to be retired after incorporating valued guidance into the Design Manual.
  • Design Manual Chapter 1430 - Transit Facilities might be one place where that would fit. It already provides some guidance on park and ride lot design.
  • The WSF Terminal Design Manual, Chapter 530 - Parking (June 2012) provides parking guidlines for WSF applications. Also, Chapter Chapter 300 - Accessibility of that new manual covers parking spaces by linking the practitioner to Sections 208 and 502 of the 2010 ADA Standards for Acccessible Design, which seems quite useful.

1. Current Status: Solicit ideas from Regions and Areas for where they would like this guidance placed in the DM.

Comment period
12/18/12 - 1/11/13
Read comments received

2. Next step: Use region/area comments to help determine where to place the guidance in the DM and then post it here for typical reivew and comment. This is looking like a project for the 2014 revision cycle.

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.
