Any final assessment of fees may include a requirement for the payment of interest on the principal amount of the fee to compensate the Developer for the time value of money given current and expected levels of inflation or deflation. However, in including such a requirement, the City Council may consider the probable deterioration in the public improvements over time which may reduce the value of the public improvements to the assessed property. The City Council may reduce, or eliminate any requirement for the payment of interest, as compensation for expected deterioration in the public improvements over time or as reasonableness, determined under Section 17.68.080, requires. Normally interest is offset by the depreciation of improvements. (Ord. 2003-2, amended, 2003; Ord. 10-82, amended, 1992)
