The E-911 ballot measure to improve emergency services communications infrastructure across Grays Harbor County passed with overwhelming support.

The countywide measure, which needed a simple majority to pass, has the backing of more than 63 percent of the voters after the latest count Friday night. More than 10,250 voters back the measure with fewer than 6,000 opposing it. There are about 3,300 ballots left to count.

Sales tax in the county will go up one-tenth of one percent to pay for improvements, including installing new radio towers, that would cost around $8 million, according to one estimate. The emergency services infrastructure upgrades would benefit the Grays Harbor Communications Center which runs the countywide E-911 dispatching.

GHCC services 30 agencies across the county. The only two fire, EMS or law enforcement agencies that operate in the county not serviced by GHCC are the Washington State Patrol and the Chehalis Tribal Police Department.
