REVENUES AND CHARGES DISTRICT REVENUES The District derives its revenue from two primary sources: charges levied on landowners and water users, and income from property taxes. Income from charges on water users is classified as operating revenue and varies with the amount of water sold. Non-operating revenue is not a function of the volume of water sales or purchases, and consists primarily of property taxes, interest, standby and availability charges, and grants. Within each of these two categories, the accounting is further subdivided by zone of benefit. Zone 3 relates to the operation of Hernandez and Paicines reservoirs, and Zone 6 relates to the importation and distribution of CVP water. The Zone 6 budget is by far the larger of the two, and revenues during fiscal year 2008 totaled $12.0 million. Approximately 21 percent of that amount was operating revenue from sales of CVP water and 53 percent was from property taxes. The remaining 26 percent came from interest, grants and other sources. DISTRICT CHARGES Some of the revenue received by the District stems from charges that are set by the District and adjusted annually in March. These include a standby and availability charge, water service charges for CVP water, power charges, and groundwater charges. The power charge reflects the energy cost of pumping CVP water to each subsystem of the distribution network, with higher charges for high-elevation subsystems. The current charges are shown in Table 9 and historical charges are tabulated in Appendix F, Table F-1. Charges for CVP water users were increased slightly from 2007. The standby and availability charge is a uniform per-acre charge assessed on all parcels that presently have access to CVP water (an active or idle turnout from the distribution system). The charge has remained at $6 per acre for over 10 years, which is the maximum charge allowed under the District’s formation act. Water service charges vary by type of user, reflecting the user categories established by the U.S. Bureau of Reclamation (USBR) for all CVP contractors. The water service charges consist of USBR fixed and variable costs that are assigned differently to agricultural users and M&I users, as itemized in Appendix F, Table F-2. In March 2007, the District’s contract with USBR was renegotiated to remove existing capital costs from the unit purchase cost of water. A separate repayment plan was established for existing capital cost. Annual Groundwater Report for Water Year 2008 December 2008 San Benito County Water District 42
