Ark. Code Ann. § 14-89-603: Assessment and collection

(a) The assessment of the value of property for taxation shall be made on a unit basis each year by the county assessor in the same manner as public utilities generally assessed by the Arkansas Public Service Commission, and the value thereof shall be returned on the personal property assessment book.

(b) The county clerk shall then extend the amount annually of the district school tax thereon on the tax books, and the taxes shall be collected by the county tax collector along with other taxes.

(c) In case of nonpayment, the remedy shall be by mandamus against the board of directors or commissioners of the improvement district and not by sale of the district's property.
