Thurston County Road Standards - 2026 Update

If you missed the Thurston County Public Works virtual learning session on the updated Road Standards, we recorded it for your benefit. Whether you're a contractor, developer, engineer, or property owner, understanding local road and development standards is an important part of creating safe, reliable infrastructure. If you've worked on projects in Thurston County before, you're likely familiar with navigating Road Standards and development requirements that help guide the design and construction process. For community members who may not work directly in development, these standards play an important role in shaping the roads, sidewalks, drainage systems, and other public infrastructure we use every day. They establish consistent requirements for how transportation elements are designed and built, helping ensure projects are safe, accessible, durable, and aligned with the county's long-term planning goals. From new residential neighborhoods and commercial developments to roadway improvements and utility projects, Road Standards provide a framework that helps create a connected transportation network while supporting public safety, mobility, and quality of life throughout Thurston County.
