KIVI-TV reports the county near the Oregon border is expected to get tens of thousands of visitors eager to witness the first coast-to-coast total solar eclipse seen in the U.S. in nearly a century.

A county disaster services spokesman says the commissioners passed the declaration Monday so they could ask the state for assistance in case more resources are need.

The declaration states that the solar eclipse may cause risk to public safety, financial damage, excess cost for labor, clean up and property damage in Washington County.

It will be in effect until the end of August.
