This chapter is adopted for use by the Washington state department of transportation to implement chapter 47.50 RCW for the regulation and control of vehicular access and connection points of ingress to, and egress from, the state highway system within unincorporated areas that are under the jurisdiction of the Washington state department of transportation. However, this chapter and chapter 468-52 WAC may be used, as a default, by cities that are the permitting authorities if they have not adopted an enacting ordinance as required under chapter 47.50 RCW.

This chapter describes the connection permit application process and procedures, including a preapplication conceptual review process, and requirements for closure of unpermitted and nonconforming connections to the state highway system.
