Washington Revised Code Title 36. Counties § 36.120.070. Submission of ballot propositions to the voters

(1) Beginning no sooner than the 2007 general election, two or more contiguous county legislative authorities, or a single county legislative authority as provided under RCW 36.120.030(8), upon receipt of the regional transportation investment plan under RCW 36.120.040, may submit to the voters of the proposed district a single ballot proposition that approves formation of the district, approves the regional transportation investment plan, and approves the revenue sources necessary to finance the plan. For a county to participate in the plan, the county legislative authority shall, within ninety days after receiving the plan, adopt an ordinance indicating the county's participation. The planning committee may draft the ballot proposition on behalf of the county legislative authorities, and the county legislative authorities may give notice as required by law for ballot propositions, and perform other duties as required to submit the proposition to the voters of the proposed district for their approval or rejection. Counties may negotiate interlocal agreements necessary to implement the plan. The electorate will be the voters voting within the boundaries of the proposed district. A simple majority of the total persons voting on the single ballot proposition is required for approval.

(2) The participating counties shall submit a regional transportation investment plan at the 2007 general election as part of a single ballot proposition that includes, in conjunction with RCW 81.112.030(10), a plan to support an authority's system and financing plan, or additional implementation phases of the system and financing plan, developed under chapter 81.112 RCW. The regional transportation investment plan shall not be considered approved unless both a majority of the persons voting on the proposition residing in the proposed district vote in favor of the proposition and a majority of the persons voting on the proposition residing within the regional transit authority vote in favor of the proposition.
