(A) However, all such assessments shall be made payable in installments so that not more than ten percent (10%) shall be collectible in any one (1) year against the wishes of the landowner.
(B) In the event that any landowner avails himself or herself of this indulgence, the deferred installments of the assessed benefits shall bear interest at the rate of six percent (6%) per annum and shall be payable only in installments as levied.
(2) Installment payments of less than ten dollars ($10.00) per acre per year are not subject to the ten-percent limitation in subdivision (b)(1)(A) of this section unless a majority of the board of commissioners agrees that the ten-percent limitation should apply.
(c) If any landowner shall pay in full the assessment of benefits against his or her land as provided in this section, the land shall not be further liable by reason of the assessment or any reassessment of the land except a reassessment because of changed plans as provided in § 14-117-408. It shall then be liable only to the extent of the increase in assessment, if any, because of the greater benefit thereby received. However, in case of any such additional assessment for greater benefit, any landowner who shall have paid his or her previous assessment in full shall have the privilege of paying in full the increase in assessment in the manner provided in this section.
