Engineering Projects & Information


The Engineering division is comprised of our technical and design people, including surveyors, engineers, inspectors, property and permitting services agents, and other professionals. These folks work together to design and and oversee the construction of projects throughout the county, and help the public through the permitting and construction of private projects.
We will endeavor to make project status and information available to the public on our website, and also using Twitter for projects that have a major impact on the public. Should you have a question about one of our projects, check here for the project coordinator, or call us at (360)867-2300. You can also call us with questions about survey or right-of-way.
