Assessments made under this article shall become due and payable at the office of
the county comptroller thirty (30) days after the confirmation thereof; provided,
however, that any assessment confirmed after March 1, 1970, and before the effective
date of this article, for work not commenced on the effective date of this article,
shall not be due and payable at the office of the county comptroller until thirty
(30) days after the board of county commissioners files written notice with the county
comptroller that such assessments are due and payable. At the time such notice is
filed, the board of county commissioners shall mail (by first class mail) a copy of
such notice to each person whose name and address may be known or reasonably ascertained,
who is the owner of any lot, parcel or tract of land assessed, and such owners, notwithstanding
any other provision of this section, may at any time within thirty (30) days after
the filing of such notice, deposit with the clerk of the board of county commissioners
the amounts apportioned and assessed against each parcel of land for credit against
the assessment. All assessments not paid within such periods shall thereupon become
payable in not more than ten (10) equal annual installments, the number to be determined
by the board of county commissioners at the time of the confirmation and approval
of the assessment roll, with interest at not more than two (2) percentage points higher
than the interest rate paid by the county on the bonds issued under section 21-136 to finance the improvements per annum from the expiration of such thirty (30) days;
but any assessment becoming so payable in installments may be paid at any time together
with interest accrued thereon to maturity.
