TABLE C-1
City of Rialto - 2024 Water and Wastewater Rate Study
Water Rate Design Calculations
613 Step 13. Calculate Volume Charge (Cost of Service Based Rates, Test Year FY 24/25) 614
615 1. Base costs. For the portion of base costs recovered through the volume charge, a single unit cost is calculated and is app lied to all tiers. 616
617 Total Base Costs from Customers Paying Volume Charges $2,817,730 Line 364 above. Already excludes base charges from Private FP and Hydrant customers 618 Less Base Costs from MF>49 ($190,200)
619 Total Base Costs from Customers Paying Tiered Volume Charges $2,627,531 620 Percent of Base Costs Recovered from Volume Charges 0.0% 621 Total Base Costs Included in the Volume Charge $0
622 ccf/year 3,135,711 Excludes Private Fire Protection and Hydrant Connections, and MF > 49 623 Component of Tiered Volume Charge that is for Base Costs $0.00 624
625 2. Peaking Costs. Peak Month Costs are Allocated into the Tiered Costs According to Peak Month use in Each Tier 626
627 Total Peaking Costs from Customers Paying Volume Charges $5,330,801 628 Less Peaking Costs from MF>49, Private FP, Hydrant Customers ($348,463) 629 Total Peaking Costs from Customers Paying Tiered Volume Charges $4,982,338 630 Percent of Peaking Costs Recovered from Volume Charges 100.00% 631 Total Peaking Costs Recovered from Volume Charges $4,982,338 632 ccf/year 3,135,711 Excludes Private Fire Protection and Hydrant Connections, and MF > 49 633 Component of Tiered Volume Charge that is for Peaking Costs $1.59 634
635
636 3. Source Specific Costs. The least expensive sources are grouped into Tier 1; The most expensive sources are grouped into Ti er 2. MF and Hydrant/Fire Protection 637 water use is distributed among all sources proportionately to adjusted production from each source. Production per source adju sted by factor converting CY 22 ccf/year to estimated FY 24/25 ccf/year. 638 Ccf/year

652 (1) See Table B-10
653 (2) This table calculates how source-specific costs are incorporated into the three-tier volume charge. To calculate this, only the consumption that 654 the tiered rate structure is applicable to should be considered. Therefore, the consumption for MF>49 and fire protection c ustomers (which will not be a tiered rate structure) 655 is excluded.

670 Methodology: the source-specific costs in Item 3 are based on FY 23/24 costs. Because of the schedule requirements of this 2 024 Rate Study update, it was not possible to revise this 671 analysis for projected FY 24/25 costs. Source of supply costs in the RWS draft FY 24/25 budget are higher than in the FY 23/ 24 budget. The increase in costs from the FY 23/24 budgeted costs and the draft 672 FY 24/25 costs will be recovered from all tiers.

CITY OF RIALTO/RIALTO UTILITY AUTHORITY

NOTICE OF PUBLIC HEARING FOR PROPOSED INCREASED WATER AND

SEWER/WASTEWATER RATES

Hearing Date & Time: June 25, 2024, 6:30 PM
Hearing Location: City Council Chambers
150 S. Palm Avenue, Rialto, CA 92376

Notice is hereby given that the Rialto City Council/Rialto Utility Authority Board will hold a public hearing to comply with California Proposition 218, (California Constitution Article XIIID, Section 6) on Tuesday, June 25, 2024, at 6:30 PM or as soon the reafter as can be heard, in the Council Chambers located at 150 South Palm Avenue, Rialto, California. The purpose of the public hearing is to consider proposed modifications and increases to water and sewer/wastewater charges for services furnished by the City/Rialto Utility Authority and to hear and consider objections and protests to the proposed water and sewer/wastewater rate modifications.

THIS NOTICE SHALL ONLY APPLY TO CUSTOMERS WHO RECEIVE THEIR WATER AND/OR

SEWER/WASTEWATER SERVICES FROM RIALTO WATER SERVICES, AS AUTHORIZED BY THE CITY OF RIALTO/RIALTO UTILITY AUTHORITY.

THIS NOTICE DOES NOT APPLY TO WEST VALLEY WATER DISTRICT (WVWD) OR FONTANA WATER COMPANY (FWC) WATER CUSTOMERS.

LOCATION OF REPORT: A report by FG Solutions, LLC, dated May 2024, describing details of the water and sewer/wastewater rate modifications and increases and the method used to calculate the rate modifications and increases (the “Report”) has been prepared. The Report is on file at Rialto City Hall, 150 S.

Palm Avenue, and can also be found on the City of Rialto website. A copy of the Report can also be reviewed or obtained upon request by calling (909) 820-2525 ext. 2062 or by emailing [email protected].

AMOUNT OF PRO POSED RATE MODIFICATIONS FOR YOU: The amounts of water and sewer/wastewater rates (existing and proposed) are included as Exhibit “A”.

REASON FOR THE PROPOSED MODIFICATION OF WATER AND SEWER/WASTEWATER RATES: The proposed modification of Rialto’s wat er and sewer/wastewater rates is to make the rate structure consistent with the cost of services provided. For water, the increases are primarily to cover an accrued deficit 156
and operational costs for services provided by Rialto Water Services. For sewer, the increases are to cover increased operating costs, and partially for capital improvements needed to the wastewater treatment plant. The revenue from the modified rates and charges will not be more than the funds required for the City/RUA to provide adequate water and sewer/wastewater services.

BASIS FOR PROPOSED MODIFICATIONS OF WATER AND SEWER/WASTEWATER RATES: A description of how the modifications were calculated can be found in the Report on file at Rialto City Hall and on the City of Rialto website starting May 2024. A copy of the Report can also be reviewed or obtained upon request by calling (909) 820-2525 ext. 2062 or by emailing [email protected].

PROCEDURE FOR HEARING AND DETERMINING MAJORITY PROTEST: At the time stated above, the Council/RUA Board will hear and consider all objections and protests, if any, to the proposed water and sewer/wastewater rate modifications and other matters described in the Report. The Council/RUA Board may continue the hearing from time to time. Prior to the close of the hearing, if written protests against the proposed modified water and/or sewer/wastewater rates are presented and not withdrawn by a majority of the record owners of the parcels or rate-paying tenants of the parcel that would be subject to the modified water and/or sewer/wastewater rates, the City/RUA may not impose the modified water and/or sewer/wastewater rates; instead, water and/or sewer/wastewater rates would continue at their exist ing, previously-approved amounts. If, at the close of the protest hearing, there is no majority protest as described above, the Council/RUA Board may approve the water and/or sewer/wastewater rate modifications, as proposed or as changed by the Council/RUA Board, to be effective commencing January 1, 2025.

PRESERVING THE RIGHT TO CHALLENGE: Any person who wants to preserve the opportunity to file a lawsuit challenging the proposed water and sewer/wastewater rate modifications, if imposed, or other matters described in the Report must file a written protest with the Council /RUA Board, stating the specific grounds of the protest. Any grounds not stated in a written protest filed with the Council/RUA Board before the close of the protest hearing on June 25, 2024, will be deemed waived and may not be raised in any subsequent lawsuit.

HOW TO PROTEST THE PROPOSED RATE INCREASES: All owners and tenants of property receiving water and/or sewer/wastewater service, and interested persons are invited to attend the Public Hearing noticed above. Written protests must be received (not postmarked) by the City Clerk before or during the public hearing. Council/RUA Board will not count written protests submitted after the conclusion of the public hearing.

In compliance with Proposition 218, a ny protest submitted by e -mail or other electronic means will not be accepted. The protest must be signed by the property owner(s) or tenant(s) and must include the assessor’s parcel number(s) or street address(es) of all property(ies) serviced, and your statement that you protest the increase in either the water or sewer rates. Should the property owner(s) or tenant(s) protest both the water and the sewer rate, then one protest will need to be completed protesting the water rate, and another protest will need to be completed protesting the sewer rate. Only one written protest per identified parcel or property will be counted for purposes of determining whether there is a majority protest.

ADDITIONAL INFORMATION: For additional information and answers to questions about the proposed water and sewer/wastewater rate proceeding, contact Toyasha Sebbag, Assistant to the City Manager, at (909) 820-2525 x 2062, or [email protected].

Do you need help paying your water or sewer bill? Customers aged 65 and over or households who have incomes at or below the Low-Income Limits may qualify for a 20% discount on the “Total Sewer Flat Rate.” For more information and how to apply, call (909) 820-2661.

Por medio de la presente se notifica que el Conc ejo de la Ciudad de Rialto/la Junta de la Autoridad de Servicios Públicos de Rialto celebrará una audiencia pública para cumplir con la Proposición 218 de California, (Artículo XIIID, Sección 6 de la Constitución de California) el martes 25 de junio de 2024, a las 6:30 PM o tan pronto como sea posible, en las Cámaras del Consejo ubicadas en 150 South Palm Avenue, Rialto, California. El propósito de la audiencia pública es considerar las modificaciones e incrementos propuestos a los cargos de agua y alcantarillado/aguas residuales por los servicios prestados por la Autoridad de Servicios Públicos de la Ciudad/Rialto y escuchar y considerar las objeciones y protestas a las modificaciones propuestas a las tarifas de agua y alcantarillado/aguas residuales.

ESTA NOTIFICACIÓN SÓLO SE APLICARÁ A LOS CLIENTES QUE RECIBEN SUS SERVICIOS

DE AGUA Y/O ALCANTARILLADO/AGUAS RESIDUALES DE RIALTO WATER SERVICES, SEGÚN LO AUTORIZADO POR LA AUTORIDAD DE SERVICIOS PÚBLICOS DE LA CIUDAD DE RIALTO/RIALTO.

ESTE AVISO NO SE APLICA A LOS CLIENTES DE AGUA DE ”WEST VALLEY WATER DISTRICT” (WVWD) NI DE CLIENTES DE “FONTANA WATER COMPANY”(FWC).

UBICACIÓN DEL INFORME: Se ha preparado un informe de FG Solutions, LLC, con fecha mayo de 2024, en el que se describen los detalles de las modificaciones y los aumentos de las tarifas de agua y alcantarillado/aguas residuales y el método utilizado para calcular las modificaciones y los aumentos de las tarifas (el "Informe"). El Informe se encuentra archivado en el Ayuntamiento de Rialto, 150 S. Palm Avenue, y también puede consultarse en el sitio web de la Ciudad de Rialto.

MOTIVO DE LA PROPUESTA DE MODIFICACIÓN DE LAS TARIFAS DE AGUA Y ALCANTARILLADO/AGUAS RESIDUALES: La modificación propuesta de las tarifas de agua y alcantarillado/aguas residuales de Rialto es para que la estructura de tarifas sea coherente con el coste de los servicios prestados.

En el caso del alcantarillado, los aumentos se destinan a cubrir el aumento de los costes operativos y, en parte, a las mejoras de capital necesarias en la planta de tratamiento de aguas residuales. Los ingresos procedentes de las t arifas y cargos modificados no serán superiores a los fondos necesarios para que la Ciudad/RUA preste servicios adecuados de agua y alcantarillado/aguas residuales.
