COPALIS – Pilots and passengers should prepare for temporary runway closures at the Copalis Beach State Airport as maintenance crews install new navigation and safety aids and improved airport information signs.

The runway closure is scheduled from 7 a.m. to 3 p.m. Tuesday, March 13, and could extend through March 14. Pilots are encouraged to check notices to airmen for more information.

The safety project at Copalis is in coordination with Washington State Parks and Recreation and includes relocating the northern runway marker approximately 740 feet to the south, a location consistent with the historic northern airport landing boundary east of the north face of the largest Copalis ocean rock. Crews will also replace a missing runway end marker near the Copalis River, install new signs at Boone Creek and a new windcone at the airport.

Following the safety project the Washington State Department of Transportation Aviation will survey the airport to determine the effects of ongoing river migration and ocean erosion on the runway. Preliminary surveying showed that that the runway could have shortened by more than 1,000 feet.

As the Copalis River continues to migrate, runway length changes are anticipated in the future. WSDOT asks that pilots continue to take off and land between the visible north and south runway end markers only. The runway end markers are orange reflective signs with black arrows pointing either in a north or south direction.

Copalis is one of 17 airports operated by WSDOT and is the only known beach airport in Washington state.
