Tex. Transportation Code § 452.657

(a) On the effective date of a withdrawal from an authority:

(1) the authority shall cease providing transportation services in the withdrawn unit of election; and

(2) the financial obligations of the authority attributable to the withdrawn unit of election cease to accrue.

(b) Withdrawal from an authority does not affect the right of the authority to travel through the territory of the unit of election to provide service to a unit of election that is a part of the authority.

(c) In a unit of election that withdraws from an authority consisting of one subregion governed by a subregional board created under Subchapter O, title to all real estate in the unit of election, including improvements made by the authority, except a right-of-way or an improvement to a right-of-way, vests in the unit of election if the unit of election by resolution claims the real estate and improvements within 30 days after the effective date of the election.

(d) If the real estate and improvements are within 30 days after the effective date of the election determined by the authority to be necessary for the continuation of service to the remaining units of election, the authority may retain the use of the real estate and improvements for not longer than 15 years or the duration of the authority's remaining federal grant obligation for the facility, whichever is longer. If the authority retains the use, the authority is responsible for all operation and maintenance costs of the facility.

(e) In a unit of election with a population of less than 10,000 according to the most recent federal decennial census that withdraws from an authority consisting of one subregion governed by a subregional board created under Subchapter N, title to all real estate in the unit of election owned or partially owned by the authority, including improvements made by the authority, except a right-of-way or an improvement to a right-of-way, shall immediately vest in the authority, and the authority may continue to use the real estate and improvements in the withdrawn unit of election as may be determined by the authority to be necessary:

(1) for the continuation of service to other units of election;

(2) to satisfy the authority's remaining federal grant obligation for the real estate and improvements; or

(3) for the operation of a public transportation system as provided by Section 452.056(a).

(f) An authority is responsible for all operation and maintenance costs of the property and improvements located in the withdrawn unit of election that are owned or partially owned by the authority as described by Subsection (e).
