Beginning at the 2009 regular spring county road administration board meeting, and continuing once every four years thereafter, one or more of the WAC 136-400-010 named counties are invited to attend said meeting and request the county road administration board issue a call for projects. Based on the information provided by the counties and no later than the regular summer meeting the same year, the county road administration board, and at their sole discretion, may issue a call for projects and may include in the call additional or clarifying terms consistent with all other rules governing the county ferry capital improvement program.
