Field Surveys

Geotechnical and Topographical Surveys

The Columbia River Crossing project is conducting several surveys at locations along the I-5 corridor, focusing on areas within the highway right of way. Crews are collecting information about soil structure and stability. Information provided by the surveys will be used in the next steps of the design process.

Crews will use techniques to minimize disturbance to vegetation. In some areas, brush and trees will be trimmed to allow access to boring sites. Standard erosion controls will be used. Right-of-entry permits are obtained from all private property owners before current and future investigations can take place on any non-government owned land. Additionally, all property owners are notified 48 hours in advance of work that is to occur on their property.

If you have questions or concerns, please call the project office at 866-396-2726.
