The Road Maintenance Division makes up the ground crews that perform maintenance and preservation activities for the county.
One such preservation activity, the County Arterial Preservation Program (CAPP), is a resource dedicated to the preservation of paved county arterials throughout Washington State. CAPP is funded with 0.45 cent of the fuel tax which generates approximately $30 million per biennium. These funds are allocated directly to the counties to help them avoid costly roadway failures had the surface repairs been delayed. 2020 CAPP Map
