C. The sewer system development fee for new town side sewer service shall be computed using the following formula:

[Current ENR CCI/Base ENR CCI] x [Total ERU Cost]



= Engineering News Record Construction


Cost Index for Seattle on Sept., 1989.


= 4932

Current ENR CCI

= Engineering News Record Construction Cost Index for Seattle for the month that the complete service application is filed.

Total ERU Cost

= The total number of ERUs for the new service using the ERU schedule, Article 5, of this chapter, applied to the following cost schedule:

First ERU


Second through fourth ERU


Fifth through ninth ERU


Tenth through fourteenth ERU


Fifteenth through nineteenth ERU


Twentieth or more ERUs


D. The sewer system development fee for any expansion of, change in use of, or addition to, a building or structure that raises the ERU rating of an existing service connection, shall result in the obligation to pay an incremental sewer system development fee, computed by assessing the ERU cost only to the difference between the old and the new ERU rating established for that service.

E. The sewer system development fee for public sewer service outside the town limits shall be two times the fee determined for public sewer service within the town limits.

F. For the purposes of this chapter an existing service connection shall be defined as a connection to the public sewer system that has paid a hook-up fee specific to that connection, and paid a minimum of single-family user fees specific to that connection from the time of payment of the hook-up fee, or meets the criteria established under Section 13.12.280 of this article. Any active connection that was connected prior to the establishment of any hook-up or connection fees by the town and that has been paying a minimum of single-family user fees as a separate and individual service connection from any other service connection, shall also be considered an existing service connection under this chapter.

G. The payment of the cost of the installation of a connection from the main line to the property shall not constitute the establishment of an existing service connection.

H. All sewer system development fees collected shall be paid into a special interest-bearing capital dedicated reserve account of the town or into a special sinking fund account for debt service payments as determined by the town council.

I. Monies collected from the sewer system development fee shall be used solely to finance increases in the public sewer system capacity including but not limited to the following:

K. In the event that any owner does not actually connect to the town sewer system within six months of the granting of the permit referred to above, he/she may apply for a rebate of his/her sewer system development fee, in writing, for up to eighteen (18) months from the first permit date of issue. In such event, ninety (90) percent of the sewer system development fee shall be rebated to said owner. The ten (10) percent of such fee retained by the town shall be deemed necessary to cover the town’s administrative costs and capital expansion plans made in reliance of anticipated systems development needs. All service charges and connection fees paid by the owner in such circumstances shall be entirely retained by the town. (Ord. 413 § 4.04, 1993)

13.12.280 Abandonment of service line.

A. A service line shall be presumed to be abandoned by the owner when service charges have been unpaid for a period of one year. Except as provided in subsection F of this section, upon abandonment pursuant to this section, town service can be resumed only upon payment of a new sewer system development fee.

B. If a hook-up fee has been paid to the town for a property, prior to the passage of the ordinance codified in this chapter, and such property has not been paying monthly sewer user charges, the property owner shall pay the monthly sewer user charges from the month of passage of the ordinance codified in this chapter forward at the rate determined for a single- family residence, or the service shall be deemed abandoned. The town shall give public notice of this requirement in the same manner and for the same time period as that required for passage of a town ordinance. The public sewer service cannot be restored unless a new sewer system development fee is paid.

C. If a structure served by a town system is torn down or destroyed, the owner can either voluntarily abandon the service line or prevent abandonment by paying the service charges to the town in an amount equal the charges prior to the building’s destruction.

D. Any property owner may voluntarily abandon their service line by written notice of their intention to do so to the town. Such service line shall be deemed abandoned upon receipt of said notice, and physical abatement of the line as may be required in the town’s sewer use ordinance.

E. If a service line is abandoned pursuant to this article, service charges to the property or building shall cease to accrue upon the effective date of the abandonment. However, abandonment pursuant to this article shall not relieve the owner of their obligation to pay the sewer utility balance due prior to the date of abandonment.

F. In cases where the sewer service line has been abandoned for failure to pay service charges for a period of one year as set forth in subsection A of this section, a new bona fide purchaser for value of the property subject to the abandonment shall have the option to restore service to the property if the following conditions are met:

1. The new purchaser must exercise such option within one year of the date of abandonment of the town sewer service to the property;

2. The new purchaser must be a bona fide purchaser for value, which for the purposes of this subsection, shall mean a person, firm, corporation, company or entity that has purchased or been assigned the property for an amount that is equivalent to at least fifty (50) percent of the fair market value of the property, or at least fifty (50) percent of the current assessed value of the property as determined by the Okanogan County assessor, whichever is less. The new purchaser shall be required to produce the documentation substantiating the requirements of this subsection, and “new purchaser” shall not mean any assignee, transferee, heir or devisee, or entity, unless they meet the definition of a bona fide purchaser for value;

1    If more than one use category is applicable to a particular building, the building will be divided into areas of similar use categories and the ERU units for the building will be computed by adding the ERU units determinations for each use category area. For uses not specifically described in this schedule, the number of ERU units to be assigned shall be determined on a case-by-case basis by the wastewater treatment plant operator and approved by the town council. No less than 1.0 ERU unit will be assigned any building or portion thereof that has a separate side sewer.

2    In computing area, the “total usable area” shall be used. “Total usable area” includes but is not limited to: kitchen areas, serving areas, washing areas, occupant areas, waiting rooms, storerooms, restrooms, lunch rooms, halls, entryways, showrooms and retail areas.

3    In computing the number of fuel nozzles, the town will only count the number of nozzles that can dispense fuel at the same time. For the purposes of this schedule, fuel includes all types of gasoline and diesel fuel.

4    For the purpose of gas station/retail store combinations, the retail space assessed at the retail store square footage rate shall be equal to the total retail space less four hundred (400) square feet or zero, whichever is greater. This adjustment is to account for the estimated retail space of a gas station without any general retail space.

5    A residential building or portion thereof shall be considered multifamily if it has more than one kitchen area.
