RATE SETTING PROCESS

GENERAL MANAGER'S RECOMMENDATION

 

recommendation

RECOMMENDATION: 

Approve initiating the rate setting process a year early to allow Orange County Sanitation District to assess rates across the service area including new customer bases.

body

 

BACKGROUND

 

Orange County Sanitation District (OC San) completes a rate study every five years to determine customers’ fair and equitable share of collection, treatment, and disposal costs, develop an accurate rate model, and establish a new five-year rate schedule which ensures full cost recovery and provides support for the Proposition 218 notifications.  In March 2023, the Board of Directors adopted service fees for fiscal years 2023-2024 through 2027-2028.

 

OC San and Irvine Ranch Water District have been collaborating on the restatement of prior agreements and the transfer of flows that will effectively adjust the customer base of both agencies.  The new customers that will have their regional sewer service provided directly by OC San were not part of the previous Proposition 218 process, therefore OC San cannot assess service fees directly on those properties which are anticipated to transfer to OC San on January 1, 2027.

 

RELEVANT STANDARDS

 

                     Stable rates, no large unforeseen rate increases

 

PROBLEM

 

The new direct customers of OC San cannot be assessed sewer service fees until a new rate setting and Proposition 218 process has been completed and adopted.

 

PROPOSED SOLUTION

 

Initiate the rate setting process a year earlier than anticipated to be able to assess new customer service fees effective July 1, 2027.

 

TIMING CONCERNS

 

The rate setting process needs to commence in December 2025 to ensure new fees can be adopted for all customers and be effective on July 1, 2027.

 

RAMIFICATIONS OF NOT TAKING ACTION

 

OC San will not be collecting service fees from the new direct customers that will be receiving service.  Without a new rate study and Proposition 218 process, OC San cannot equitably charge service fees to all the customers in the service area.

 

PRIOR COMMITTEE/BOARD ACTIONS

 

March 2023 - Approved Ordinance No. OC SAN-58 entitled: “An Ordinance of the Board of Directors of Orange County Sanitation District Adopting Regional Sewer Service Charges and Repealing Ordinance No. OCSD-49”.

 

ADDITIONAL INFORMATION

 

Adopting service fees consists of multiple steps prior to the Board of Directors approving the new rates.  The following timeline is necessary to meet the requirements to adopt service fees to be effective July 1, 2027:

 

December 2025

Issue a Request for Proposal for a Comprehensive Rate Study

March 2026

Award a contract for a Comprehensive Rate Study

December 2026

Receive and file the Comprehensive Rate Study

February 2027

Mail Proposition 218 Notifications and first reading of the   Ordinance

March 2027

Public Hearing, Second Reading, and Adoption of the Ordinance

July 2027

Ordinance takes effect

FINANCIAL CONSIDERATIONS

 

If the rate setting process is not completed a year earlier than anticipated, OC San will forego potential revenue from the new direct customer base.
