(A) Ordinance limits costs; exceptions. The ordinance ordering the improvements shall include a statement that the assessments which can be levied against the affected properties will be limited to the amount shown on the schedule approved in the ordinance adopted under § 8-4-6 of this chapter, except under the following circumstances:
(1) Actual construction costs exceed estimated construction costs, but only to the maximum of an additional 15%;
(2) Land acquisition costs exceed the estimated costs; and/or
(3) Separate and additional elements of cost are incurred in construction or for other items which are of a nature generally not foreseen and included in the construction costs at the time of estimate. Such is to be based upon experience and similar projects in the past.
(B) Limit increase. The Council may by ordinance further limit the increase in assessments over the estimates as it deems appropriate. Further, the notice required in § 8-4-4 of this chapter must contain the provisos of subsection (A) of this section in order for the assessments to be higher than the amount shown on the schedule.
