ISSUE
An uncodified ordinance passed by four affirmative votes is needed to change the annual SSC. District
Code and State Law require that a public hearing be held before such an ordinance may be adopted.
BACKGROUND
On June 4, 2015, the Board accepted and approved a comprehensive Wastewater Cost of Service Study
which assessed the cost of providing service to each of Central San' s customer classes and updated
rates to equitably recover these costs. The study resulted in recommendations to create a new residential
SSC rate for accessory dwelling units, as well as several changes to non-residential SSC rates based on
the strength and flow characteristics of those user groups and Central San' s cost to provide service to
those groups.
On June 1, 2017, the Board received and accepted the Central San Comprehensive Wastewater Master
Plan (CW MP)which identified costs for capital improvements over the next 20 years. The CW MP was
broken into three phases covering the first five-year period, second five-year period and the remaining 10-
year period. Four drivers were identified: (1) replacement of aging infrastructure to maintain performance
and reliability; (2) capacity of existing facilities to expand the capacity and redundancy(flows and loads) of
some equipment and processes (not to address population growth); (3) impact of further regulations to
protect human health and the environment; and (4) sustainability of infrastructure through optimization
resiliency, resource recovery and energy projects. These drivers were used to identify projects in the
CW MP over the 20-year period.
I n October 2022, staff and Raftelis Financial Consultants began an updated Cost of Service review
consistent with Board Policy B P 030 Cost of Service Studies. This effort included a review of updated
treatment plant flow and strength data as well as updated non-residential water consumption data.
The Cost of Service methodology included:
• a review of updated revenue requirements;
• a review of customer classifications used for sewer billing;
• an allocation of costs to causative components; and
• adjustments and changes to both the rates and the rate structure.
The review identified:
• updated rates to reflect the updated water consumption, treatment plant flow, and treatment plant
strength data;
• that a separate rate class for Accessory Dwelling Units (AD Us)was warranted based on a review of
water consumption data for parcels with and without AD Us.
On January12, 2023, the Board of Directors held a workshop to review anticipated revenues and
expenses and:
• provide guidance on SSC rates;
• confirm the number of years for the proposed SSC rate schedule;
• discuss funding levels for the rate stabilization fund; and
• confirm financing alternatives of the Capital Improvement Program.
The Proposition 218 notice notifying customers of the proposed rates was approved by the Board of
Directors on January 19, 2023 and was mailed to Central San's property owners shortly thereafter. The
Board of Directors scheduled the public hearing to receive input on the proposed changes in SSC for
April 20, 2023.

Page 3 of 16
Legal notices were published on April 6 and April 13, 2023, in the Contra Costa Times and the San
Ramon Valley Times circulation areas of the East Bay Times for this public hearing.
Note that the FY 2023-24 Budget will be considered at a separate public hearing which is currently
scheduled for June 1, 2023.
As of April 12, 2023, nine valid, written protests have been received. Any additional, written protests
received after April 12 will be included in the final tally presented at the public hearing.
ALTERNATIVES/CONSIDERATIONS
The Board of Directors could choose to give alternative direction to staff.
FINANCIAL IMPACTS
The proposed SSC rate changes are estimated to generate an additional $9.7 million dollars over two
years when compared to the budgeted FY 2022-23 SSC revenue.
COMMITTEE RECOMMENDATION
This matter was not reviewed by a Board Committee.
RECOMMENDED BOARD ACTION
1. Conduct a public hearing to receive comment and consider adopting uncodified Ordinance No. 327
establishing a schedule of Sewer Service Charge (SSC) rates in accordance with District Code chapter
6.24.030, increasing the annual SSC for residential and non-residential customers for the next two fiscal
years consistent with the table below:
Effective Date July 1, 2023 July 1, 2024
Percent change betweeno 4%
/o
+5.9 and -11.6/o (all rate classes)
Single Family Residence Rate $697 $725
(per residential unit)
As shown in the Proposition 218 Notice

developed and instituted a Sewer Service Charge Program to finance the services and
facilities furnished by Central San; and
WHEREAS, it is reasonable and necessary that all users of Central San's wastewater
and household hazardous waste collection, treatment, recycling, reuse and disposal
services and facilities, including those temporary users served under Special Discharge
Permits, contribute their appropriate portion of the funding for such Central San services
and facilities; and
WHEREAS, the Board of Directors (Board) has reviewed the current Schedule of Sewer
Service Charge Rates and has determined that the annual residential sewer service

increased by $25 per multifamily residential unit for FY 2024-25 as set forth below in
Exhibit A; and
WHEREAS, the Board has reviewed the current Schedule of Sewer Service Charge
Rates and has determined that a new rate class for Accessory Dwelling Units (ADUs)
should be created and that the annual Sewer Service Charge rates for ADUs should be
set at $339 per residential unit for FY 2023-24 and increased to $353 per residential unit
for FY 2024-25 as set forth in Exhibit A; and
WHEREAS, the Board has reviewed the current Schedule of Sewer Service Charge
Rates and has determined that the annual non-residential sewer service charge rates
should be adjusted as set forth below in Exhibit A; and

April 20, 2023 Special Board Meeting Agenda Packet- Page 655 of 724
Page 8 of 16
Central Contra Costa Sanitary District
Ordinance No. 327
Page 2 of 4
WHEREAS, in adopting this Ordinance, the Board finds that:
a. Written notices of the proposed increase in sewer service charge rates were sent
by first class U.S. mail to parcel owners who receive sewer service from Central
San, using data provided by Contra Costa County Assessor's Office, at least 45
days prior to the public hearing on the proposed increase conducted on
April 20, 2023.
b. All legally valid protests against the proposed increase in the sewer service
charge rates, including those provided in person, by facsimile, e-mail and
U.S. mail, were considered and tallied at the public hearing conducted on
April 20, 2023, and Central San was not presented with valid protests by a
majority of the owners of the identified parcels affected by this change.
c. The amount of the charge imposed does not exceed the proportional cost of the
service attributable to the properties receiving service and the charge is only
imposed on those properties actually receiving service or those for which service
is immediately available.
d. This action is categorically exempt from the California Environmental Quality Act
(CEQA) pursuant to Section 15273 (a) (1-4) of the District CEQA Guidelines.
NOW, THEREFORE, the Board of Central San does ordain as follows:
Section 1 (To be Uncodified)
The "Schedule of Sewer Service Charge Rates" as set forth in full in Exhibit "A" to this
Ordinance, which exhibit is incorporated in full herein by this reference, is hereby
adopted in uncodified form pursuant to the provisions of District Code Section 6.24.030.
As of the effective date of this Ordinance, sewer service charges shall be charged at
such rates and for such categories of users as set forth in said Schedule of Sewer
Service Charge Rates and shall remain in effect until amended or replaced by
ordinance.
Section 2
All ordinances, parts of ordinances and any provision of Ordinance No. 304 in conflict
with the provisions of this ordinance are repealed. The provisions of this ordinance,
insofar as they are substantially the same as existing provisions relating to the same
subject matter, shall be construed as restatements and continuations thereof and not as
new enactments. To the extent the sewer service charge rates or any portion thereof is
determined invalid or unconstitutional, or during any period where the new rates are
stayed due to a legal challenge, such portions of Ordinance No. 304 shall remain in
effect and such rates and charges due thereunder for any categories of users shall
remain due and payable as if those portions of Ordinance No. 304 had not been
April 20, 2023 Special Board Meeting Agenda Packet- Page 656 of 724

repealed.
With respect, however, to violations, rights accrued, liabilities accrued, or appeals taken,
prior to the effective date of this ordinance, under any ordinance, or part of an
ordinance, such ordinance or part of an ordinance shall be deemed to remain in full
force for the purpose of sustaining any proper suit, action, or other proceedings, with
respect to any such violation, right, liability or appeal.
Section 3
Prior to imposing the rates set forth under this ordinance for FY 2024-25, the Board
shall consider at a noticed public hearing prior to June 30, 2024, Central San's
proposed budget, its financial condition, projected capital and operations and
maintenance costs, as well as other factors which bear on Central San's revenue
requirements, to determine whether the increased amounts set forth herein for FY 2024-
25 are still necessary. If the Board concludes by a majority vote that sewer service
charges for less than the amount set forth in this ordinance for FY 2024-25 will produce
adequate revenues for those years, the Board may, by resolution, fix the sewer service
charges for FY 2024-25 to be imposed at appropriate amounts up to the maximum of
the rates set forth herein without an amendment of this ordinance. In such case, the
resolution shall clearly set forth such lesser charges that are to be imposed and those
charges shall remain in place until further action of the Board. If the Board determines
the rates set forth in the table for FY 2024-25 are appropriate for imposition, no further
action of the Board shall be required.
Section 4
This Ordinance shall be a general regulation of Central San and shall be published once
in the Contra Costa Times and San Ramon Valley Times newspapers of general
circulation of the East Bay Times within the Central San service area, and shall be
effective on July 1, 2023. This ordinance shall be kept on file with the Secretary of the
District.

April 20, 2023—Public Hearing
Cost of Service Update
State Law and Central San's Board Policy 030 require
periodic Cost of Service updates to ensure Central San's ►/
rates reflect the cost to provide service to each user group.
The 2023 review identified that a new rate class for +�
Accessory Dwelling Units (ADUs) was appropriate based the '
volumes of wastewater generated by parcels with ADUs.
The 2023 review also resulted in adjustments to rates for
multi-family residential and non-residential user groups
based on the wastewater flows and strengths received from
each user group and Central San's actual costs.
