The total amount assessed against any lot or parcel of land shall not exceed the value of benefits received from the improvement.
Except as otherwise provided in the City Charter, and this chapter, monies raised by special assessments to pay the cost of any local improvement shall be held in a special fund to pay such cost or to repay any monies borrowed therefor.
The funds in each special assessment account shall be used only for the improvement project for which the assessment was levied except as otherwise provided in the City Charter.
Any borrowing of money for the construction of improvements enumerated in this chapter shall be reduced in the total sum prepaid by affected property owners; provided, however, that owners prepaying their share of any special assessment shall nevertheless remain liable to pay interest attributable to their share of the special assessment if prepayment is made after the sale of any bonds or the borrowing of any monies for the construction of any improvement enumerated in this chapter.
