If a district issues its original bonds under Section 51.450(b)(2) of this code and later desires to issue bonds payable in whole or in part from taxes or to levy a tax for maintenance purposes, the district shall hold a hearing to exclude land, and at the time provided by law, shall hold another hearing to adopt a plan of taxation.
