13.08.050 System Development Charges – Designated – Method of Computation.
A. The System Development Charge (SDC) to connect to a city sanitary sewer shall be computed by unit or Equivalent Dwelling Unit (EDU). Unit charges will be computed based on classification of service at the rate and charges as follows:
1. Residential Method.
a. Single family dwelling units, including manufactured homes:
CALCULATION: One EDU = One unit
b. Duplexes, apartments, condominiums, dormitories, convalescent/residential care facilities, hotels and motels in which the units include individual kitchens:
CALCULATION: One EDU = One unit
c. Dormitories, convalescent/residential care facilities, hotels, and motels in which the units do not include individual kitchens:
CALCULATION: One EDU = Two units (in the case of convalescent/residential care facilities, one unit=one bed)
d. Bed and breakfast facilities and other similar commercial lodging facilities:
CALCULATION: One EDU for the first five bedrooms plus one EDU for every two bedrooms over five.
e. Recreational vehicle park:
CALCULATION: One EDU = Two recreational vehicle spaces with sewer hookups.
The calculations for the residential method shall apply whether the dwelling unit is occupied or not. The calculated charge includes all facilities such as common laundries, kitchens and recreation areas, provided they are intended for the sole use of the residents and guests. If the structure also contains commercial operations available for use by the general public, the charges for those facilities used for commercial operations shall be calculated using the fixture count method.
An individual manufactured home located on a platted site will be charged for the SDC on the same basis as any other structure. A site for a manufactured home unit located within a manufactured home park will not be charged for each change of a manufactured home unit if the sanitary sewer connection has a trap and vent system independent of the structure.
2. Fixture Count Method.
a. This method shall apply to all nonresidential uses, when the Industrial Method is not required to be used. The Fixture Count Method shall apply to all commercial, nonmetered industrial uses, restaurants, laundries, Laundromats, schools, hospitals, public facilities, swimming pool filters, and all other similar nonresidential uses. The fixture unit values shall be as listed in subsection (A)(2)(b) of this section.
CALCULATION: One EDU = 16 fixture units.
b. Fixture unit value shall be a shown below. Any fixture unit rating not addressed in this table shall be calculated pursuant to the current Oregon State Plumbing Specialty Code.

1Fixture unit values for garbage disposals of 3/4 horsepower or less, installed in nonresidential applications, shall be based on the proposed use of the facility. Uses associated with commercial food processing, preparation, handling, or group food service (cafeterias) shall be charged 16 fixture units. Uses for individual employee support (e.g. employee lunchrooms) shall not be separately charged.
Note that a separate water meter is required for car washes, and that adjustments to the SDC for car washes may be made based on actual water use after six months of operation.
c. Industrial Method. Industrial connections are for those structures used primarily for manufacturing. Minor and major industrial connection and sewer service charges cover only the industrial waste/wastewater portion of the Industrial User’s discharge. The minor and major Industrial User must also pay connection and sewer service charges, based upon fixture units, for its nonindustrial wastewater discharge. There are three industrial categories as follows:
i. Category I. Dry Industrial User does not generate or discharge any industrial waste or wastewater. Industrial Users that discharge less than 50 gallons of industrial wastewater on any one day may be included in this category with the approval of the Director.
CALCULATION: One EDU = 16 fixture units or fraction thereof.
ii. Category II. Minor metered water use or wastewater discharge is less than 25,000 gallons per day (gpd).
CALCULATION: One EDU = 300 gpd. If waste discharged is not known, then the fixture unit rates will be used. Any adjustment in connection charge will be made after six months of operation.
iii. Category III. Major metered water use or wastewater discharge is equal to or greater than 25,000 gpd or strength of waste discharged is more than:
– 700 mg/l Chemical Oxygen Demand (COD);
– 300 mg/l Biochemical Oxygen Demand (BOD);
– 350 mg/l Total Suspended Solids (TSS);
– 8 mg/l Total Phosphorus (TP);
– 25 mg/l Ammonia (NH3)
CALCULATIONS: The Director shall select one or more of the following calculations for determining the connection charge:
– One EDU = 300 gpd average value;
– One EDU = 0.70 pounds BOD per day average value;
– One EDU = 1.4 pounds COD per day average value;
– One EDU = 0.70 pounds TSS per day average value;
– One EDU = .11 pounds NH3 per day average value;
– One EDU = .028 pounds TP per day average value.
Such selection shall be made on the basis of the impact the Industrial User’s discharge is anticipated to have upon the sewerage system and shall be aimed at ensuring that the Industrial User in question pays his/her fair share in light of the impact of its discharge, as determined by the city. The city may, in its discretion, require the user to separate its industrial wastewater discharge from its nonindustrial waste discharge.
B. Large parcel depth over 120 feet or one-half block shall be subject to additional unit charges for any units lying therein and the cost of sewer line extensions required to service same.
C. Where a sewer is financed and constructed by a developer for city ownership and operation, the facility development fee will be waived and only the SDC will be levied.
D. All construction will conform to the applicable city and Oregon State Plumbing Specialty Code standards. The city reserves the right to reject any sewer constructed for connection to the sewer main. (Ord. 4987, 2015).
