Geology & soils

Use this information to analyze and document impacts on geologic and soil condition and to identify potential risks from geologic hazards.

Determine the scope of the geology and soils analysis

All projects require a geology and soils analysis. Review the Geology and Soils Discipline Report Checklist (PDF 355KB) to help identify the scope of the analysis needed for the project.

Contact Garrett Jackson, Garrett.Jackson@wsdot.wa.gov, for help creating a scope of work for the geologic and soils analysis.

Slow down – lives are on the line.

In 2022, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Each year about 670 people are killed nationally in highway work zones. In 2022, Washington had six 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.
