13.10.020 System of charges.
A. There is imposed a system of charges on each developed parcel of real property within the city to operate the stormwater program. The charges are deemed reasonable and necessary to fund administration, planning, design, construction, operation, maintenance, repair, improvement and replacement of all existing and future storm and surface water facilities, including the accumulation of reserves and the retirement of any associated debt.
B. The following charges are established for all developed parcels of real property in the city. The charges for all such parcels shall be computed by multiplying the basic charge for each impervious surface unit (ISU) times the total number of ISUs per parcel. ISUs shall be measured for rate of computation purposes to the nearest one-tenth of an ISU. The minimum charge shall be based on one ISU for a general facility charge or monthly user fee.
1. General Facilities Charge. A one-time charge per ISU for new development for the planning, design, and construction of capital Improvements associated with the City stormwater drainage system and facilities.
2. Monthly User Fee. The minimum monthly fee shall fund the operation, maintenance and administration of the City stormwater utility.
3. Single-Family and Duplex Residential Parcels. The charge shall be based on one ISU per month for each single-family or duplex residential parcel.
4. Undeveloped Parcels. Undeveloped parcels shall not be assessed a GFC or monthly user fee.
5. Other Parcels (Commercial, Industrial, and Multi-family). The charge for all parcels, except single-family or duplex residential parcels and undeveloped parcels, shall be based upon the total amount of impervious area as expressed in ISUs.
C. All storm rates and fees referenced in this code chapter will be passed by council resolution. (Ord. 2979 § 1, 2017; Ord. 2822 § 2, 2010; Ord. 2787 § 2, 2008; Ord. 2773, 2007; Ord. 2772 § 4, 2007; Ord. 2601, 2002; Ord. 2599, 2002; Ord. 2596, 2002; Ord. 2488 § 2, 1999)
