Planning Studies Review and Approval Process Memorandum (PDF 285KB)
- It is highly recommended that all WSDOT planning studies follow the same signature review process detailed in the memo. The M2 Team provides subject matter expert review in a predictable and effective manner.
- However, Proviso funded studies often have their own rules and regulations as well as specific directions from the Legislature.
- There are also extra steps to this process if the planning study is a Planning and Environmental Linkages (PEL) study.
Slow down – lives are on the line.
In 2023, speeding continued to be a top reason for work zone crashes.
Even one life lost is too many.
Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.
It's in EVERYONE’S best interest.
95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
