File Number: 25-067 <br />The three key elements of the Wastewater Rate Study include: <br />1.Financial projections using historical and estimated future operational and CIP <br />expenditures; <br />2.Flow and wastewater strength projections using historical usage data and anticipated <br />changes; <br />3.An evaluation of customer class and fee structure <br />Financial Projections <br />There is a projected increase in costs due to increased staffing costs and projects as part of the <br />10-year CIP to address aging infrastructure and stricter requirements from the State Water Board <br />for nutrient reduction. In addition, the proposed sewer rates support maintaining at least one year <br />of operating funds in reserve, as is standard practice for utilities. This level allows the Water <br />Pollution Control Plant Enterprise Fund to absorb unexpected changes or disasters without <br />reliance on the General Fund. <br />The City analyzed the upcoming capital improvement needs for the wastewater enterprise over <br />the next 10 years. The CIP plan was presented to City Council on October 21, 2024. The plan <br />aims to address the aging infrastructure with upgrades to the Water Pollution Control Plant, sewer <br />pipelines, and lift stations. While some of these costs are offset by grants, the remainder comes <br />from sewer fees. <br />In July 2024, the San Francisco Bay Regional Water Quality Control Board (“Water Board”) <br />imposed limits for the first time on the quantity of nitrogen that can be discharged to San <br />Francisco Bay. Complying with this requirement will require changes to the WPCP. The CIP Plan <br />sets forth a strategy for identifying cost-effective changes while maintaining flexibility to meet <br />lower limits if necessary. However, because the costs for compliance with this requirement are <br />not yet determined, additional debt financing is not recommended over the next five years to <br />reserve future debt capacity if necessary. <br />Flow and Strength Projections <br />Residential estimates are based on average home size in San Leandro and median water <br />usage. Commercial usage is based on historical flow data and standard loading by type of <br />business. Industrial usage is based on measured historical flow and load strength. There is <br />currently no anticipated significant increase in new customers. <br />Customer Classes <br />Sewer service fees are assessed within three customer classes: <br />1.Residential: Flat fee for single family homes and multifamily units <br />2.Commercial: Fees based on water flow by category of business <br />3.Industrial: Fees based on flow and loading charges <br />A new fee structure is proposed for commercial users. The current structure specifies rates for <br />certain types of industries, with most businesses falling into an “all other” category. Customers will <br />now be categorized as low, medium, or high based on industry standards for flow strength. <br />The proposed fees increase the sewer rates by 8% for fiscal year 2025-2026 and by 9% for fiscal <br />years 2026-2027 through 2029-2030. Because the rate study also includes a recalculation of <br />rates relative to one another, this may vary slightly by customer class in the first year. <br />Page 2 City of San Leandro Printed on 9/4/2025
