(a) Before the confirmation election, the governing body of each municipality located in the proposed authority, by resolution, and the commissioners court of each county in which unincorporated areas are located in the proposed authority, by order, may confirm the participation of the municipality or county in the process of developing an initial service plan and rate of tax.

If a contiguous city refuses to participate in the regional transportation authority, the boundaries of the contiguous municipality shall be excluded from the regional transportation authority proposed or created by the principal municipality or county of the principal municipality and may not be included in the initiating process or the confirmation procedure for the proposed authority.
(c) If proceedings to create a regional transportation authority are begun, the territory included in a subregional transportation authority created by a contiguous municipality is excluded from the proceedings and the contiguous municipality need not comply with Subsection (b).
