RCW 36.78.070(1) authorizes the county road administration board to establish standards of good practice for the administration of county roads and the efficient movement of people and goods over county roads. The purpose of this standard of good practice is to set forth the requirement that each county provide for the accommodation of utilities within its right of way. In order to effectively administer its authority to:

(1) Grant utility franchises and permits on county roads as provided in chapter 36.55 RCW;

(2) Exercise overall responsibility for county roads and bridges as provided in chapter 36.75 RCW; and

(3) Exercise its police power; each county legislative authority shall adopt a generally applicable written policy ("utility policy") to provide administrative, procedural, and technical guidance for the installation, replacement, adjustment, relocation, and maintenance of all above and below ground utilities and other transmission or transport facilities located within all county road rights of way.
