13.16.220 System development charges.

A. It is the policy of the city that all property owners seeking to connect to the city sewer system shall bear their equitable share of the cost of the general facilities of such system. Therefore, a system development charge may be paid either (1) upon the approval of a building (side) sewer permit application and prior to any construction, or (2) deferred according to subsection (D) of this section to the city at the city’s finance department. The cost of such system development charge shall be computed according to the following schedule:

1. The fee for connection to the city sewer system shall be assessed per equivalent residential unit (ERU) as defined in SMC 13.16.030. All commercial, institutional, and industrial users discharging domestic sewage shall pay the system development charge per ERU as defined in SMC 13.16.030 for the amount of sewage that would be discharged to the city sewer system at full use of the intended facility or building. The system development charge per ERU is specified in the following list. This list shall be used in determining the number of ERUs for the building unless the applicant has a minimum of three previous years of water meter records at their present location that would more accurately reflect the waste load generated by the facility. The city engineer may choose to use the data submitted rather than determining the number of ERUs from the list. All ERU calculations used to determine system development charges shall be carried to the nearest 0.01 ERU.

Single-family residence	1.0	ERU per unit
Multifamily residence	0.75	ERU per unit
Accessory dwelling units	0.5	ERU
Retail	1.25	ERU per 1,000 sq/ft of building
Restaurant	0.14	ERU per occupant load
Assembly	0.08	ERU per occupant load
Office	0.8	ERU per 1,000 sq/ft of building
Industrial domestic	0.1	ERU per 1,000 sq/ft of building
High cubed warehouse	0.03	ERU per 1,000 sq/ft of building
Mobile home park	1.0	ERU per space
Motel	0.65	ERU per room
Service station	4.0	ERU per pump
Mini-mart	6.0	ERU per pump

Industrial waste loads shall pay a system development charge based on the number of ERUs as defined in SMC 13.16.030 (since nondomestic wastewaters are different in strength and composition). Four parameters in the definition of an ERU shall be weighted as follows in calculating the number: Flow, five-day BOD and TSS shall each be weighted at 0.3 and ammonia shall be weighted at 0.1.

2. Sixty-five percent of the fee shall be used for the treatment/disposal system upgrades.

3. Thirty-five percent of the fee shall be used for pump stations, force mains and sewer interceptor system upgrades.

B. Effective October 1st of each year, the system development charge shall be adjusted according to the Seattle Construction Cost Index (SCCI). The schedule of system development charges for the sewer is specified in the Sumner utility rate and fee schedule, as amended from time to time, available online and at City Hall.

C. The system development charges collected under this chapter shall be deposited in the utilities capital reserve fund and used only for utility system improvements.

D. Deferral of Payment of System Development Charges. An applicant for a building permit or site development permit may request a deferral of the full system development charge payment until final inspection or 18 months from the date of original permit issuance, whichever occurs first. Deferral of system development charges, and the application process for a deferral, shall be in accordance with the provisions and requirements of SMC 3.50.115(A)(1) through (11), as currently written or hereafter amended.
