The governing bodies of two or more fire protection jurisdictions located within reasonable proximity, upon receipt of the regional fire protection service authority plan under RCW 52.26.040, may certify the plan to the ballot, including identification of the revenue options specified to fund the plan. The governing bodies of the fire protection jurisdictions may draft a ballot title, give notice as required by law for ballot measures, and perform other duties as required to put the plan before the voters of the proposed authority for their approval or rejection as a single ballot measure that both approves formation of the authority and approves the plan. Authorities may negotiate interlocal agreements necessary to implement the plan. The electorate is the voters voting within the boundaries of the proposed regional fire protection service authority. A simple majority of the total persons voting on the single ballot measure to approve the plan and establish the authority is required for approval. However, if the plan authorizes the authority to impose benefit charges or sixty percent voter approved taxes, then the percentage of total persons voting on the single ballot measure to approve the plan and establish the authority is the same as in RCW 52.26.050. The authority must act in accordance with the general election laws of the state. The authority is liable for its proportionate share of the costs when the elections are held under RCW 29A.04.321 and 29A.04.330.
