12.12.050 Drainage system plant investment charge.
(1) The city council hereby finds and determines that the capital cost of the city’s drainage system includes pumps, collection pipelines and rights-of-way. The capital cost of such system has been borne by the city and its drainage system users. Such drainage system will be utilized by newly developed properties, and the capital cost, as applied to buildings presently served, is determined per each equivalent unit.
(2) Beginning January 1, 2019, and thereafter, in addition to other fees imposed by ordinance or pursuant to agreements, there is hereby imposed upon the owners of property seeking to develop within the city limits a drainage plant investment charge determined by multiplying the total number of equivalent residential units (ERU) by the capital cost per ERU.
(a) Residential. An equivalent residential unit (ERU) is determined to be 3,500 square feet of impervious area. This is based on a lot size of up to 10,000 square feet. For plant investment charges for residential lots larger than 10,000 square feet, the ERUs will be calculated on the same basis as nonresidential development with a minimum of one ERU per lot.
(b) Nonresidential Development (Includes Multifamily Dwellings). Drainage plant investment charges for nonresidential development shall be calculated based on the number of equivalent residential units of impervious area of the proposed development, including fractions thereof. For example:
(i) Five thousand five hundred square feet of impervious area/3,500 = 1.57 ERUs.
(ii) Six thousand four hundred square feet of impervious area/3,500 = 1.83 ERUs.
(3) The drainage plant investment charges shall be established and calculated as follows:
(a) Prior to January 1, 2019, and for all projects for which a complete application has been submitted or a letter of completeness has been issued for any development permit prior to January 1, 2019:
(i) Drainage system valuation: $3,730,204.
(ii) Capital cost per equivalent residential unit (ERU): $802.00.
(b) On or after January 1, 2019 (excluding projects described in subsection (3)(a) of this section):
(i) Drainage system valuation: $8,780,236.
(ii) Capital cost per equivalent residential unit (ERU): $1,414.00. (Ord. 1461 § 1 (Exh. 1), 2018; Ord. 1405 § 1 (Exh. 1), 2015).
