Texas Transportation Code - TRANSP § 452.707. Participation by Other Entities

(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.

(b) This chapter does not require a contiguous municipality to be a part of or participate in a regional transportation authority.  Within 60 days after the date of initiation of the process provided by Section 452.701 by a principal municipality or a county of the principal municipality, a contiguous city may by resolution of its governing body refuse to participate in the proposed regional transportation authority.  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).
