<br />BARTLE WELLS ASSOCIATES 8 | Pag e <br /> City of San Leandro Draft 2024 Wastewater Rate Study <br />• Interest earnings are projected based on the annual beginning fund balance multiplied by the projected <br />interest rate (2%). The interest rate projections are based on recent and anticipated interest rates. <br />Expense Assumptions <br />• Operating and maintenance costs are primarily based on the 2024/25 budget. <br />• Operating costs are projected to escalate at 8% for the first year and 3.5% per year for the remaining four <br />years to account for cost inflation. <br />• Debt service projections are based on outstanding debt schedules and projected issuances of new debt. <br />• Capital improvement costs are based on the most recent engineering cost estimates. Capital costs include a <br />3.5% annual construction cost inflation factor for the next five years. <br /> <br />3.4 Cash Flow Projections <br />Cash-flow projections were developed based on assumptions and key drivers of future rate increases described <br />above. The projections were used to determine the wastewater utility’s annual revenue requirements and project <br />required wastewater rate revenue increases. The cash-flow projections incorporate the latest information <br />available from the City’s budget, annual reports, capital spending projections, metered water demand data, as <br />well as a number of reasonable assumptions developed with input from the City. The overall rate revenue <br />increases shown for each of the following scenarios are designed to fund the City’s cost of providing service, <br />maintain roughly balanced budgets, maintain healthy debt service coverage, and maintain prudent reserves. The <br />proposed rate increase in the first year is lower than the remaining years to mitigate the impacts from rate <br />structure adjustments. The projections indicate the need for increases for wastewater rate revenues for each of <br />the next five fiscal years. Actual impacts to customers’ wastewater bills will vary based on strength category and <br />water use, due to the outcome of the updated cost-of-service analysis and change in rate structure. <br /> <br />In future years, the City can re-evaluate its finances and revenue requirements and adjust rates as needed based <br />on updated projections. However, while the City always has the flexibility to implement rate adjustments that are <br />lower than adopted pursuant to Proposition 218, future rates cannot exceed adopted increases without going <br />through the Proposition 218 process again. Rates adopted pursuant to Proposition 218 are essentially future rate <br />caps. <br /> <br />The following figure visually depicts the cash-flow projections with the proposed rate increases for the next five <br />years. Projected expenses are summarized into key categories. The figure also shows the projected fund reserves <br />at the end of each fiscal year. <br />
