§ 41-8-121 — Assessments generally

(a) The board of directors shall, on or before the third
Monday in July of each year, certify to the board of county
commissioners of the county within the watershed improvement
district in which assessed land is located the amount of the
annual installments of assessments against the land, together
with a fair proportionate amount of the estimated operating and
maintenance charges apportioned to the land for the next
succeeding year. Thereupon the county commissioners shall
certify to and deliver the assessment roll to the county
assessor of the county and the county assessor shall extend the
amounts so certified on the tax roll as a flat special
assessment against the land benefited. The assessments shall be
subject to the same interest and penalties in case of
delinquency as in the case of general taxes, and shall be
collected at the same time and in the same manner as in the case
of general taxes; provided, that the assessments shall become
due and payable only at the times and in the amounts as may be
determined by the board of directors.
(b) The board of directors in making the annual
assessments and levies as herein provided, shall take into
account the maturing indebtedness for the ensuing year as
provided in its contracts, the maturing of bonds and interests
on all bonds, and deficiencies and defaults of prior years, and
shall make ample provisions for the payment thereof; provided
however, that no one (1) yearly call for assessment by the board
of directors shall be in an amount to exceed ten percent (10%)
of the actual amount necessary to defray the cost of the
construction of the improvement or project.
