(a) If after the hearing the commissioners court finds that creation of the district is feasible and will promote the public safety, welfare, health, and convenience of persons residing in the proposed district, the commissioners court shall grant the petition and fix the district’s boundaries. If the proposed district, according to its boundaries stated in the petition, is located wholly in a county with a population of more than 3.3 million, the commissioners court may amend the petition to change the boundaries of the proposed district if the commissioners court finds the change is necessary or desirable. For the purposes of this provision, the population of the county is determined according to the most recent federal decennial census available at the time the petition is filed.
(b) If the proposed district will include territory in the municipal limits or extraterritorial jurisdiction of one or more municipalities, the commissioners court of the county in which the municipality is located must determine if the district would still meet the requirements prescribed by Subsection (a) if the territory in the municipality’s limits or extraterritorial jurisdiction is excluded from the district. The commissioners court must make this finding for each municipality the territory of which will be included in the district.

(c) If the commissioners court finds that the proposed district does not meet the requirements prescribed by Subsection (a), the commissioners court shall deny the petition.
