EXCLUSION OF COUNTY AREA.

(a) The residents of any county area of the district, on petition of at least 15 percent of the registered voters in that county area, may request that the board, in conjunction with the next regularly scheduled directors' election, hold a referendum to determine whether to exclude that county area from the district.

(b) The petition must be submitted to the board not later than the 45th day before the date of the election.

(c) The board shall call and add a referendum under this section to the ballot of the May directors' election in the county area.

(d) Exclusion of a county area from the district requires approval by a majority of the voters voting on the proposition: "The _________________ county area of the Barton Springs-Edwards Aquifer Conservation District shall be excluded from the Barton Springs-Edwards Aquifer Conservation District."

(e) The exclusion of any county area from the district is effective on June 1 following approval of the referendum. On and after that date:

(1) the boundaries of the district shall be redefined to exclude the county area;

(2) the imposition and collection of district taxes or user fees in the county area shall cease;

(3) the offices held by any directors elected from the county area shall terminate; and

(4) any other matters provided by law or by agreement with any person affecting the authority and operations of the district shall be automatically redesignated and redefined to be consistent with the exclusion of the county area.
