The powers and duties of the county legislative authority in relation to roads and bridges, and the qualifications and duties of the county engineer are detailed in Title 36 RCW. This chapter reiterates the formal relationship between the legislative authority and its county engineer and requires that certain written policies be adopted to insure the efficient and productive operation of the road department.

In this chapter and throughout Title 136 WAC, the term "county engineer" shall mean both "county road engineer" and "county engineer," as those terms are used in Title 36 RCW.
