Texas Election Code - ELEC § 42.008. Consolidating Precincts in Special Election

(a) In a special election for which use of county election precincts is required, the commissioners court may consolidate, on the recommendation of the county election board, two or more county election precincts into a single precinct if the polling place is located so it will adequately serve the voters of the consolidated precinct.

(b) If county election precincts are consolidated for a countywide election, at least one consolidated precinct must be situated wholly within each commissioners precinct.
