A. General. Since 1978, with the passage of Proposition 13, capital construction costs for new domestic water service infrastructure have been borne by developers through the WSBFC. The WSBFC is assessed on all new development and redevelopment projects within the district’s service area.

The WSBFC is comprised of three components: (1) dwelling unit/building unit charge; (2) meter surcharge; (3) supplemental water supply charge.

1. Dwelling Unit/Building Unit Charge (DU/BUC). The DU/BUC provides funds to construct backup facilities to maintain domestic water service to new developments at peak day flow conditions.

The DUC is applicable to residential-type development including duplexes, apartments, condominiums, hotels, motels and recreational vehicle and trailer park spaces. For purposes of calculating the DUC, each recreational vehicle, each motel room and each hotel room shall constitute 0.5 dwelling units.

The BUC is based on the DUC calculation and is applicable to all nonresidential development projects. To calculate the BUC, the equivalent number of dwelling units (EDU) for a nonresidential development is determined, then multiplied by the DUC.

The BUC for a cooling tower is calculated as shown in Table A-4 of the Sanitation System Rules and Regulations.

2. Meter Surcharge. The standard service connection for the district consists of a one-inch service line with a three-quarters-inch meter. Meters larger than three-quarters inch allow greater flow rates; therefore require more backup facilities to maintain domestic water service. The meter surcharge is equal to a modified DUC multiplied by a factor to account for the increased flows through the larger meters.

The meter surcharge is applicable to all new service connections in which the meter is larger than three-quarters inch and to existing service connections in which an increase in meter size is requested.

For existing service connections, when the meter size is increased, the meter surcharge will be the difference between the meter surcharge for the old and new meters. The size of the meter installed will be determined by the general manager.

3. Supplemental Water Supply Charge (SWSC). The supplemental water supply charge is levied for the purpose of funding new water sources to supplement existing groundwater supplies used for domestic water.

4. Payment. The DU/BUC, meter surcharge and SWSC and other charges as may be required shall be paid prior to the district issuing the first meter to the development. At the discretion of the general manager, the DU/BUC, meter surcharge, and SWSC may be paid at alternative times. For existing service connections, the meter surcharge shall be paid at the time of application for an increased meter size.

The district may apply a credit for the development’s DU/BUC towards construction of off-site infrastructure not exceeding the total amount of the DU/BUC. Credits are not applicable for the meter surcharge and SWSC.

B. Amount. See Appendix N of this chapter. (Ord. 1399.12 § 4-5, 2017)
