§ 15-2-7. MONTHLY DRAINAGE CHARGE.

(A)

The monthly drainage charge for each benefitted property shall be calculated by applying the base rate to the total impervious cover on the benefitted property and applying an adjustment factor to account for the percentage of impervious cover on the benefitted property.

(B)

The formula for computing the monthly drainage charge is:

MDC = BR × IC × AF ÷ 12

MDC = monthly drainage charge

BR = base rate

IC = square feet of impervious cover on benefitted property

AF = adjustment factor

(C)

The director may credit the monthly drainage charge based on voluntary installation of on-site stormwater control measures that exceed the applicable requirements of City Code, state law, or a development agreement with the City. A credit under this subsection:

(i)

may not exceed an amount equivalent to a 50% reduction in the square feet of impervious cover under the formula established in Subsection (B) of this section; and

(ii)

must be based on criteria, established by administrative rule, that tie the amount of the credit to the overall value of voluntary stormwater control measures in reducing runoff from the benefitted property.

(D)

After computing the monthly drainage charge as described in subsections (A) and (B), the monthly drainage charge for single family residential properties may be modified by limiting any increase in the charge to be assessed October 1, 2015—October 1, 2016 as compared to the charge assessed October 1, 2014—October 1, 2015 by a percentage, if established by separate ordinance.
