TAXES FOR BONDS

(a) At the time the district issues bonds payable wholly or partly from ad valorem taxes, the board shall provide for the annual imposition of a continuing direct ad valorem tax, without limit as to rate or amount, while all or part of the bonds are outstanding as required and in the manner provided by Sections 54.601 and 54.602, Water Code. (b) The board's order to issue bonds and authorize an ad valorem tax must provide that the imposition of the tax ends and the district's authority to assess and collect the tax ends on the retirement of the bonds for which the tax was originally authorized unless the district voters authorize the extension or continuation of the ad valorem tax in a subsequent bond election.
