Texas Health and Safety Code - HEALTH & SAFETY § 775.020. Overlapping Districts Located Wholly in Populous County

(a) This section applies only to a district located wholly in a county with a population of more than three million.

(b) If the territory in a district created under this chapter overlaps with the boundaries of another district created under this chapter, a district converted under this chapter, or a district converted under former Section 794.100, the most recently created district may not provide services in the overlapping territory that duplicate the services provided by the other district at the time the overlapping district was created.

(c) For purposes of this section, a district is created on the date on which the election approving its creation was held. If the elections approving the creation of two or more districts are held on the same date, the most recently created district is the district for which the hearing regarding approval of the petition for creation of the district was most recently held.

(d) The creation of a district with boundaries that overlap the boundaries of another district does not affect the validity of either district.
