Gophers are threatening the Yakima airport.
The city council approved a $30,000 contract Tuesday with the U.S. Department of Agriculture to poison the burrowing rodents.
The Yakima Herald-Republic reports gophers have been tunneling near the runway at Yakima Air Terminal. Officials fear they could weaken the runway or create a problem if a plane rolls off the pavement.
Gophers also could attract hawks, which could collide with planes.
