(a) The commissioners court of a county on its own motion may hold a hearing on the question of annexing a defined area to a road district and shall hold a hearing on the question on receipt of a petition requesting the annexation signed by:
(1) owners of real property the taxable value of which is a majority of the taxable value of real property in the defined area according to the county tax roll; or
(2) at least 50 property owners in the defined area if there are more than 50 property owners in the defined area.
(b) The commissioners court shall give notice of the hearing in the manner required for notice of a hearing on creation of a road district.

(c) If after the hearing the commissioners court finds that annexation of the defined area to the district is feasible and practical and would benefit the area and the district, the court may annex the area to the district. The order annexing the area to the district is not required to include all of the real property described by a petition requesting the annexation if the court finds that a modification is necessary or desirable.
(d) The annexed area is subject to any bonds, notes, or other obligations issued or taxes imposed before the area was annexed to the district.
(e) The commissioners court shall, in the order annexing the area to the district, order an election to be held in the district, including the area to be annexed, on the questions whether the annexed area should assume:
(1) the bonds, notes, or other obligations issued or taxes imposed by the district before the area was annexed to the district; and
(2) its part of the bonds of the district payable in whole or part from taxes that have been approved by the voters but have not been issued, and the imposition of the district’s ad valorem tax on the taxable property in the annexed area for the payment of the bonds.
(f) At the election held under Subsection (e) the commissioners court, in a separate proposal, may submit the question whether the court should be authorized to issue bonds for the construction, purchase, maintenance, and operation of macadamized, graveled, or paved roads and turnpikes, or in aid of those purposes, in the annexed area.
(g) Notice of an election held under this section shall be given and the election shall be held in the manner provided by law for a bond election in the district.
(h) If the majority of the votes received in the election favor the assumptions proposed under Subsection (e), the district may issue its approved but unissued bonds even though the boundaries of the district have been changed by the annexation since the original election approving the bonds.
(i) The commissioners court shall provide in its order annexing an area to the district that the annexation does not take effect unless the voters approve the assumptions proposed under Subsection (e).
(j) The commissioners court may provide in its order annexing an area to the district that the annexation does not take effect unless the voters approve an issuance of bonds proposed under Subsection (f).
