Agenda Item 5

CITY OF YUBA CITY

STAFF REPORT
Date: July 1, 2025
To: Honorable Mayor & Members of the City Council;
From: Human Resources Department
Presentation By: Gina Rowland, Interim Human Resources Director Summary
Subject: Local 1/AFSCME 57, Police First Level Managers and First Level Managers Side Letters
Recommendation: Adopt a Resolution approving side letters with Local 1/AFSCME 57, Police First Level Managers and First Level Managers for short-term disability benefits and a side letter with Local 1/AFSCME 57 for reporting of leave hours for Wastewater Treatment Facility Operators
Fiscal Impact: The short-term disability programs are paid for by participating employees' contributions. There is no additional cost to the City to approve the reporting of leave hours for Wastewater Treatment Facility Operators as employees would use existing leave accruals.

Purpose:

To approve the side letters with Public Employees' Union Local 1/AFSCME 57 (Local 1), Police First Level Managers and First Level Managers for short-term disability and reporting of leave hours for Wastewater Treatment Plant Operators.

Council's Strategic Goal:

These side letters address the City Council's Strategic Goals of being business friendly and infrastructure because the employees who are in these bargaining units provide services to the public and maintain and oversee the City's infrastructure.

Background:

State Disability Insurance
On February 20, 2024, Council approved the move to new short-term disability programs. Local 1, Police First Level Managers (on behalf of their non-sworn members) and First Level Managers elected to transition to the short-term disability program run by the State of California ("SDI"). Since employees began using SDI, Local 1 requested a meeting to discuss how benefits will be coordinated for those receiving SDI benefits. The purpose was to clarify the procedures for supplementing their disability benefit payments with their leave banks.

Reporting of Leave Hours for Wastewater Treatment Facility Operators On February 6, 2024, Council approved the Local 1 Memorandum of Understanding (MOU). The term of the MOU is February 10, 2024 through June 2026. On September 3, 2024, Council approved a side letter with Local 1 to change the shift schedules for Wastewater Treatment Facility Operators to 12- hour shifts (6:00 a.m. to 6:00 p.m., and 6:00 p.m. to 6:00 a.m.).

This new shift schedule amounts to an employee working three 12-hour shifts one week (36 hours), and three 12-hour shifts plus one 8-hour shift in the second week (44 hours) for a total of 80 hours in a pay period. In order for the graveyard shift to be covered from 6:00 p.m. to 6:00 a.m., employees assigned to graveyard and working their 8-hour day receive an additional four (4) hours of overtime each pay period (eight (8) hours plus four (4) hours overtime for a 12-hour shift). When a graveyard shift employee takes vacation or is sick on their 8-hour day, they lose the opportunity to work four hours of overtime. Also, existing MOU language in Section 19.10(b) states that an operator who is absent from work due to sickness or vacation will use leave accruals in proportion to their assigned shift and according to scheduled hours for each day they are absent.

Analysis:

State Disability Insurance
Eligible employees may elect to use their accrued leave to supplement disability benefit payments in order to receive the equivalent of a full paycheck (gross basis). Staff determined that it was necessary to clarify the process for employees who choose to use their accrued leave balances while receiving SDI payments.

Employees who wish to use accrued leave must notify Human Resources within five (5) business days of receiving their disability benefits, specifying the leave banks and the amount of SDI benefits received so that the City can determine the number of hours to be used. This clarification is intended to prevent inadvertent overpayments.

In the event of an overpayment, the employee will be notified and must promptly coordinate with the Finance Department to arrange repayment.

Reporting of Leave Hours for Wastewater Treatment Facility Operators The recommended side letter gives Wastewater Treatment Facility Operators assigned to a graveyard shift the option to use an additional four (4) hours of vacation or sick leave accruals when absent from work due to sickness or vacation on their 8-hour day. The additional four (4) hours of leave accruals would be paid at the straight-time rate, since the hours were not actually worked and are not reportable to CalPERS.

Fiscal Impact:

The short-term disability programs are paid for by participating employees' contributions. There is no additional cost to the City to approve the reporting of leave hours for Wastewater Treatment Facility Operators as employees would use existing leave accruals.

Alternatives:

1. Do not approve the side letters for short-term disability.

2. Do not approve the side letter for reporting of leave hours for Wastewater Treatment Facility Operators.

Recommendation:

Adopt a Resolution:

A. Approving the side letter with Local 1/AFSCME 57, Police First Level Managers and First Level Managers for state disability insurance
B. Approving the side letter for Local 1/AFSCME 57 for the reporting of leave hours for Wastewater Treatment Facility Operators

The City of Yuba City and the First Level Manager
Side Letter of Agreement to the
July 1, 2023 through June 25, 2027 MOU
The City of Yuba City ("City") and the First Level Managers (“FLM”) have met and conferred in good faith pursuant to the requirements of the Meyers-Milias-Brown Act with respect to this side letter amending their current Memorandum of Understanding ("MOU"), with a current term that runs from July 1, 2023 to June 25, 2027 as set forth below. This side letter to the MOU describes the Parties' full and complete agreement to transition to the California Short Term Disability Insurance (SDI) program according to the process described below, and to amend that MOU by adding the language as set forth below.

Side Letter Language- Upon approval of FLM’s application for coverage by the EDD Director, the City and FLM agree that Article 4.6- “Long Term Disability”- of the MOU will be amended as follows to incorporate SDI as the short-term disability plan for FLM:

The City provides a long-term disability program for employees.

As to short-term disability benefits, FLM has elected to transition away from the City’s short term disability program to in the CA State Disability Insurance (SDI) program, and subsequently the appropriate program application was submitted. Upon approval of the application, the City will begin withholding the required SDI contributions (including retroactive contributions to the beginning of the then-current SDI quarter) from the wages of all FLM employees. SDI benefits are not immediately available to FLM members, but rather will become available pursuant to applicable program requirements after contributions have been made for at least two SDI quarters (“the SDI Initial Contribution Period”). Based on submitting the SDI application in February 2024, the anticipated first date when SDI benefits claims could be filed would be July 1, 2024. However, the parties understand and agree that the initial benefit claim eligibility date is determined solely by EDD.

The City Program will continue to be available to FLM employees during the SDI Initial Contribution Period so long as they make or continue to make the contributions required to be withheld per the City’s Program. Assoon as FLM employees are eligible to submit claims for SDI benefits (the anticipated date being July 1, 2024), the City’s Program will no longer accept new claims from FLM employees, and no further City Program contributions will be required of FLM employees unless there are FLM employees with active City Program claims continuing to receive benefits (hereafter “City Program Holdover Claimants”). If there are City Program Holdover Claimants, the parties agree that FLM employees will continue to make City Program contributions for the duration that any City Program Holdover Claimants are receiving City Program benefits, after which time no further City Program contributions will be required of FLM employees.

4931-7782-8943.1 011024.002
Finally, it is agreed that for FLM employees receiving benefits under either a short or long-term disability insurance program, the employees may elect to use their accrued leave to supplement disability benefit payments in order to receive the equivalent of a full paycheck (gross basis). In no instance shall the combination of disability insurance payments and accrued leave or other City benefit payments exceed 100% of an employee’s typical paycheck based on working regularly-scheduled hours. Employees who wish to use accrued leave are required to notify Human Resources within five (5) business days of receipt of disability benefits to communicate the leave banks to be used and report the amount of SDI benefits received so that the City can determine the number of hours to be used. In the event of an inadvertent overpayment, the employee will be notified and must make immediate arrangements with Finance to repay the overpayment.

All other provisions of the MOU between the City and Union shall remain unchanged.

The City of Yuba City and the Public Employees’ Union, Local 1/AFSCME 57 Side Letter of Agreement to the
February 10, 2024 through June 26, 2026 MOU
The City of Yuba City ("City") and the Public Employees’ Union, Local 1/AFSCME 57, on behalf of its bargaining unit employees ("Local 1"), have met and conferred in good faith pursuant to the requirements of the Meyers-Milias-Brown Act with respect to this side letter amending their current Memorandum of Understanding ("MOU"), with a current term that runs to June 26, 2026, as set forth below. This side letter to the MOU describes the Parties' full and complete agreement to transition to the California Short Term Disability Insurance (SDI) program according to the process described below, and to amend that MOU by adding the language as set forth below.

The City and Local 1 agree that Article 9-Employee Benefit Plans, 9.8, Short Term Disability Plan of the MOU will be amended as follows to incorporate SDI as the short-term disability plan for Local 1:

Local 1 has elected to transition away from the City’s short-term disability program to in the CA State Disability Insurance (SDI) program, and subsequently the appropriate program application was submitted. Upon approval of the application, the City will begin withholding the required SDI contributions (including retroactive contributions to the beginning of the then-current SDI quarter) from the wages of all Local 1 employees. SDI benefits are not immediately available to Local 1 members, but rather will become available pursuant to applicable program requirements after contributions have been made for at least two SDI quarters (“the SDI Initial Contribution Period”).

Based on submitting the SDI application in February 2024, the anticipated first date when SDI benefits claims could be filed would be July 1, 2024. However, the parties understand and agree that the initial benefit claim eligibility date is determined solely by EDD.

The City Program will continue to be available to Local 1 employees during the SDI Initial Contribution Period so long as they make or continue to make the contributions required to be withheld per the City’s Program. As soon as Local 1 employees are eligible to submit claims for SDI benefits (the anticipated date being July 1, 2024), the City’s Program will no longer accept new claims from Local 1 employees, and no further City Program contributions will be required of Local 1 employees unless there are Local 1 employees with active City Program claims continuing to receive benefits (hereafter “City Program Holdover Claimants”). If there are City Program Holdover Claimants, the parties agree that Local 1 employees will continue to make City Program contributions for the duration that any City Program Holdover Claimants are receiving City Program benefits, after which time no further City Program contributions will be required of Local 1 employees.

Finally, it is agreed that for Local 1 employees receiving benefits under either a short or long-term disability insurance program, the employees may elect to use their

accrued leave to supplement disability benefit payments in order to receive the equivalent of a full paycheck (gross basis). In no instance shall the combination of disability insurance payments and accrued leave or other City benefit payments exceed 100% of an employee’s typical paycheck based on working regularly-scheduled hours.

Employees who wish to use accrued leave are required to notify Human Resources within five (5) business days of receipt of disability benefits to communicate the leave banks to be used and report the amount of SDI benefits received so that the City can determine the number of hours to be used. In the event of an inadvertent overpayment, the employee will be notified and must make immediate arrangements with Finance to repay the overpayment.

All other provisions of the MOU between the City and Union shall remain unchanged.

The City of Yuba City ("City") and the Police First Level Managers ("PFLM") have met and conferred in good faith pursuant to the requirements of the Meyers-Milias-Brown Act with respect to this side letter amending their Memorandum of Understanding ("MOU"), with a current term of July 1, 2023 through June 26, 2026 as set forth below. This side letter to the MOU describes the Parties' full and complete agreement to transition to the California Short Term Disability Insurance (SDI) program according to the process described below, and to amend that MOU by adding the language as set forth below.

Short-Term Disability
PFLM has elected to enroll its civilian, non-sworn members (“the Civilian Employees”) in CA State Disability Insurance (SDI) program and subsequently the appropriate program application was submitted.

Upon approval of the application, the City will begin withholding the required SDI contributions (including retroactive contributions to the beginning of the then-current SDI quarter) from the wages of all the Civilian Employees. SDI benefits are not immediately available to the Civilian Employees, but rather will become available pursuant to applicable program requirements after contributions have been made for at least two SDI quarters (“the SDI Initial Contribution Period”). Based on submitting the SDI application in February 2024, the anticipated first date when SDI benefits claims could be filed would be July 1, 2024. However, the parties understand and agree that the initial benefit claim eligibility date is determined solely by EDD.

The City Program will continue to be available to the Civilian Employees during the SDI Initial Contribution Period so long as they make or continue to make the contributions required to be withheld per the City’s Program. As soon as the Civilian Employees are eligible to submit claims for SDI benefits (the anticipated date being July 1, 2024), the City’s Program will no longer accept new claims from the Civilian Employees, and no further City Program contributions will be required of the Civilian Employees unless there are Civilian Employees with active City Program claims continuing to receive benefits (hereafter “City Program Holdover Claimants”). If there are City Program Holdover Claimants, the parties agree that all Civilian Employees will continue to make City Program contributions for the duration that any City Program Holdover Claimants are receiving City Program benefits, after which time no further City Program contributions will be required of the Civilian Employees.

Finally, it is agreed that Civilian Employees receiving benefits under either a short or long-term disability insurance program may elect to use their accrued leave to supplement disability benefit payments in order to receive the equivalent of a full paycheck (gross basis). In no instance shall the combination of disability insurance payments and accrued leave or other City benefit payments exceed 100% of an employee’s typical paycheck based on working regularly-scheduled hours. Civilian

employees who wish to use accrued leave are required to notify Human Resources within five (5) business days of receipt of disability benefits to communicate the leave banks to be used and report the amount of SDI benefits received so that the City can determine the number of leave hours to be used. In the event of an inadvertent overpayment, the employee will be notified and must make immediate arrangements with Finance to repay the overpayment.

19.10 Reporting and Allocation of Leave Hours
a. Water and Wastewater Treatment Plant Operators will report used leave accruals according to the date on which their shift would have started. b. An operator who is absent from work due to sickness or vacation will use leave accruals in proportion to their assigned shift and according to scheduled hours for each day they are absent. The sole exception is Wastewater Treatment Plant Operators who are assigned to a graveyard shift, who may use an additional four (4) hours of leave accruals when absent from work due to sickness or vacation on their 8-hour day, for a total of 12- hours of paid leave. The use of the additional four (4) hours of leave accruals is at the discretion of the employee. Notwithstanding Article 5 "Overtime," the use of the additional four (4) hours of leave accruals will not be considered hours worked and will be paid at the straight time rate. The additional four (4) hours is not considered reportable compensation to CalPERS.

All other provisions of the MOU between the City and Union shall remain unchanged.

Agenda Item 6

CITY OF YUBA CITY

STAFF REPORT
Date: July 1, 2025
To: Honorable Mayor & Members of the City Council;
From: Public Works
Presentation By: Kathy Willis, Environmental Compliance Manager Summary
Subject: Sewer System Management Plan Update Adoption
Recommendation: Adopt a Resolution adopting the City of Yuba City Sewer System Management Plan Update
Fiscal Impact: Staff time associated with implementing new state requirements reflected in the Sewer System Management Plan Update. Compliance with state regulations preserves the City's eligibility for various funding opportunities and minimizes potential fines.

Purpose:

To comply with the new Waste Discharge Requirements for sanitary sewer systems adopted by the State Water Resources Control Board.

Council's Strategic Goal:

This item addresses Council's Strategic Goal of maintaining and improving the City's Infrastructure by adopting a Sewer System Management Plan Update in compliance with state requirements.

Background:

The Sewer System Management Plan Update (SSMP) documents the City’s program to properly operate and maintain its sanitary sewer system.

In 2006, the State issued the first order requiring systems to develop SSMPs and systematically report sewage spills to the state.

Since 2008, the City has dramatically reduced the number and volume of sewage spills to the environment. This is a result of the City’s investment in rehabilitating and improving sewer infrastructure, acquisition of equipment and technology, and continual improvement in operational practices over time.

The State Water Resources Control Board issued an updated Sanitary Sewer Systems General Order in December 2022.

Analysis:

The reissued Order increases the focus on system resilience to minimize the number and volume of sewage spills contaminating the environment. The regulations require local agencies to improve resilience through condition assessments, identification of operational changes, prioritization of capital improvements, and addressing high-priority rehabilitation and repairs.

The new regulation also requires systems to submit certified audit reports on their program compliance to the State every three years. Staff is increasing training and working to update geographic information system (GIS) maps in order to comply with the new regulations.

Staff worked with the consulting firm Fischer Compliance to develop the SSMP. The plan must be updated every six (6) years.

Fiscal Impact:

Staff time associated with implementing new state requirements reflected in the Sewer System Management Plan Update. New regulations focus on increasing system resilience through prioritization of capital improvements and schedules to address high-priority rehabilitation and repairs. Compliance with state regulations preserves the City’s eligibility for various funding opportunities and minimizes potential fines.

Alternatives:

Provide staff direction regarding changes to the plan. Each Governing Board is required to approve a plan to meet the WDR requirements, therefore, there is no alternative without accepting regulatory noncompliance and associated fines.

Recommendation:

Adopt a Resolution adopting the City of Yuba City Sewer System Management Plan Update.

1185 Market Street
Yuba City, CA 95991
Dear Mr. Bybee,
We are pleased to present the new 2025 Sewer System Management Plan (SSMP) Update developed in partnership with the City of Yuba City’s management. The 2025 Update meets and exceeds compliance with the WDR (State Water Board, Water Quality Order No. 2022-0103-DWQ, Attachment D-10 and Specifications 5.4). The 2025 SSMP has been completely revised to harmonize with industry standard guidelines and incorporates the City’s latest SSMP Audit findings.

The 2025 SSMP is a declaration of what the City is doing to demonstrate full compliance with the WDR. Attachment A of the WDR (page A-4), states “A sewer system management plan is a living document an Enrollee develops and implements to effectively manage its sanitary sewer system(s) in accordance with this General Order.” We suggest that the City review the SSMP on a regular basis, and as required by the WDR, continuously document changes to its SSMP in a change log attached to the Plan.

We look forward to assisting the City wherever necessary to fully implement the new 2025 SSMP Update.

Sincerely,
James Fischer, P.E.

OVERVIEW
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 1 of 69 Introduction
This Sewer System Management Plan (SSMP) or “Plan” has been prepared for the City with technical assistance from Fischer Compliance LLC with the goal of meeting and exceeding compliance with the State Water Resources Control Board 2022 General Waste Discharge Requirements, Order No. WQ 2022-0103-DWQ for Sanitary Sewer Systems (referred to throughout this document as the WDR). The City provided all details, information and institutional insights for preparation of the SSMP. The document has been developed to meet the size, scale, and complexity of the City, serving as a “living document” used as a tool for managing and operating the City's sanitary sewer collection system. Additionally, the latest 2024 Sewer System Management Plan Guidance Manual published by the Bay Area Clean Water Agencies (BACWA) was utilized as a model for development of the document to harmonize formatting/content and incorporate recommended suggested guidance wherever possible.

The City’s commitment to meeting or exceeding regulatory requirements, along with its proactive approach to operation and management of the collection system, has served it well, as evidenced by the system’s performance relative to other agencies in the region and the state.

This SSMP includes information for both the City of Yuba City and Stonegate Village. Prior to 2004, the Stonegate Village collection system and wastewater treatment facility were owned and operated by Yuba County. However, on March 23, 2004, the County adopted Resolution No. 04-01 “Resolution of the Tierra Buena Community Services District consenting to the reorganization of the Tierra Buena Community Services District as a Subsidiary District of the City of Yuba City”. The City subsequently connected the Stonegate Village collection system to the City’s collection system and the Stonegate Village wastewater treatment and disposal facility was abandoned. Because the City has incorporated Stonegate Village into its collection system, it is appropriate to prepare one SSMP for both systems. Unless described separately herein, all descriptions of the City’s collection system, maintenance, design, capacity evaluation, etc. includes Stonegate Village.

Because Stonegate Village was historically a separate collection and disposal system, it has its own WDID, separate from Yuba City. Even though the City has assumed full responsibility for the last 20 years, the City is still required to submit a separate SSMP, separate Annual Reports, and separate audits for Stonegate Village. The City would prefer that State Water Board staff update CIWQS to remove Stonegate Village as a separate system and to include it as part of the Yuba City collection system.

Figure 1 provides key spill metrics, including data comparing Stonegate Village’s spill record with state and regional system data, while Figure 2 provides the same key metrics for the City. The City consistently performs better than both statewide and regional spill rate indices and net spill volumes for all categories of spills from its sanitary sewer collection system.

GOAL AND INTRODUCTION
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 6 of 69

1. Goal and Introduction

WDR REQUIREMENTS
Att. D-1 (pg. D-2)
“The goal of the Sewer System Management Plan (Plan) is to provide a plan and schedule to: (1) properly manage, operate, and maintain all parts of the Enrollee’s sanitary sewer system(s), (2) reduce and prevent spills, and (3) contain and mitigate spills that do occur.

The Plan must include a narrative Introduction section that discusses the following items:”

1.1. Regulatory Context

WDR REQUIREMENTS
Att. D-1.1 (pg. D-2)
“The Plan Introduction section must provide a general description of the local sewer system management program and discuss Plan implementation and updates”.

COMPLIANCE
The City is committed to fully implementing the WDR which includes addressing all requirements by integrating a wide range of programs specifically designed for ensuring the integrity and efficiency of the City’s sanitary sewer collection system. Moreover, the City is dedicated to maintaining its collection system in a systematic manner by implementing various work programs, with a focus on critical areas, to prevent spills, allowing for a comprehensive approach to maintenance. Work programs include CCTV inspections, pipe cleaning, manhole inspections, lift station maintenance, root control, source control and pipe repair, just to name a few. Work programs are described in more detail in Specifications 5.19 – Operation and Maintenance of this SSMP.

By prioritizing proactive measures and taking a comprehensive approach, the City is well-equipped with a proven track record of effectively operating its sanitary sewer collection system with the highest levels of service, complying with the WDR, and reducing/eliminating sewage spills.

1.2. SSMP Update Schedule

WDR REQUIREMENTS
Att. D-1.2 (pg. D-3)
“The Plan Introduction section must include a schedule for the Enrollee to update the Plan, including the schedule for conducting internal audits. The schedule must include milestones for incorporation of activities addressing prevention of sewer spills.”

COMPLIANCE
The City utilizes the State Water Board’s online lookup tool to ensure compliance with all required due dates for updating its SSMP and completing its required SSMP Audits (see chart below). The City’s most recent SSMP audit was completed for the period August 2021 through August 2024.

Milestones for incorporation of activities include a 3-year gravity main cleaning cycle, 3-month highfrequency cleaning cycles, a 5-year CCTV inspection cycle, 3miles per year of targeted chemical root control, and weekly lift station inspections.

The SSMP update for Stonegate Village is due August 2, 2026, and the next Stonegate Village SSMP audit is due August 2, 2025. However, as described in the Introduction section, the City would prefer that State Water Board staff update CIWQS to remove Stonegate Village as a separate system and to it include as part of the Yuba City collection system. In that case, there would be no need to submit a separate SSMP, annual reports, or audits for Stonegate Village.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Are SSMP Audits and SSMP Updates being performed as scheduled? • Has the SSMP been approved by the governing board on the required schedule (i.e., every six years)? • Are specific internally established sewer program milestones being monitored?

Additionally, the Plan Introduction section must provide reference to the Enrollee’s up-to-date map of its sanitary sewer system, as required in section 4.1 (Updated Map of Sanitary Sewer System) of this Attachment.”

COMPLIANCE
The City of Yuba City is in Sutter County and encompasses approximately 15 square miles. The existing wastewater collection system service area is approximately 7.1 square miles and includes a portion of the area within the City limits and a small area outside the City limits near Hillcrest, as shown on Figure 1.2, below. Figure 1.2 includes the Bogue Stewart area (in yellow) which is slated for future development and will be served by the collection system. Figure 1.2 also depicts the Stonegate Village collection system, at the northwest side of the City limits, with the purple force mains.

The City provides wastewater services to approximately 42,102 people (based on 14,034 residential connections and three people per connection). Most residential connections are low-density, single-family housing and much of the commercial development is retail related. There are also several minor industrial dischargers and one large industrial discharger, which generates food-processing waste. The percentage of residential, commercial, and industrial connections are shown in Table 1-1, below.

The City’s wastewater collection system includes approximately 175 miles of gravity mains ranging in pipe diameter from 4-inch to 42-inch diameter, of which approximately 70 percent are 6-inch and 8-inch diameter lines. The City also maintain 2 miles of force mains. Approximately 67 percent of the system has an installation year of 1990 or later, with 11 percent having an installation year before 1990, and the remaining 22 percent of unknown installation year. Approximately 82 percent of the system by pipeline length is composed of vitrified clay pipe. Appendix 1 contains tables detailing (a) gravity mains by diameter, (b) gravity mains by material, and (c) approximate age of the gravity mains.

In 2021, the City relined approximately 2,590 linear feet of 42-inch Techite pipe trunk line from Lincoln Road and the Garden Highway to the WWTF. The 2020 Wastewater Master Plan recommended the removal or rehabilitation of 9,420 feet of Techite reinforced plastic mortar pipe in the City’s wastewater collection system due to its high failure rate.

GOAL AND INTRODUCTION
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 10 of 69 The City owns, operates, and maintains 17 lift stations. The system also includes approximately 3.3 miles of force mains, some of which are associated with the lift stations, and some of which are associated with private septic tank effluent pumping (STEP) systems in the Stonegate neighborhood. The City maintains the STEP systems in Stonegate. The City’s force mains range in diameter from 2-inch to 24-inch and are composed of various pipe materials.

The City does not have any siphons. The City has 6 stormwater stations with pumping capacity.

The City manages its collection system data using the iWorQ software which is geared toward community development and public works departments. This web-based software allows City staff to access data from a tablet or smart phone while in the field. The City’s geographical information system (GIS) maps are integrated into iWorQ.

The City estimates that there are 15,451 upper and lower service laterals connected to the system. Private entities own and operate all these laterals.

Overall, the City is in a good position to maintain its collection system. There is one unique situation: the Stonegate Village collection system.

Stonegate Village
Stonegate Village is a residential subdivision that was outside of the City limits during development, and therefore the collection system and small wastewater treatment plant were owned and operated by Sutter County. However, in 2004, the City assumed responsibility for Stonegate Village from Sutter County. The wastewater treatment plant was decommissioned, and the collection system was connected to the City.

Stonegate Village is a residential subdivision with 108 homes, 14 mobile homes, and one elderly care home.

Each home in the subdivision collects its wastewater in an on-site 1,000-gallon reinforced concrete septic tank. The effluent from each septic tank is pumped into a pressurized collection pipeline, which transports the effluent to the City’s gravity main linked to the City’s Wastewater Treatment Facility. The City owns and operates the 105 service laterals in the system and the City’s crews conduct routine maintenance and replace the critical components at each of the 112 services a minimum of once every two years. The City would like to eventually install gravity sewer lines to replace the septic tank pumps system infrastructure.

System maps, include gravity mains, manholes, lift stations, other collection system features are available to all staff through the iWorQ database. The City continues to make efforts to accurately represent lateral information. Refer to Section 4.1- Updated Map of Sanitary Sewer System for more detail.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Are asset statistics periodically reviewed and updated as necessary? • Are omissions or errors addressed in a timely manner? • Are developments being added to the GIS maps each year? Are system maps up to date? Table 2 - City sewer connection flow classifications and connections data

3. Legal Authority

WDR REQUIREMENTS
Att. D-3 (pg. D-4)
“The Plan must include copies or an electronic link to the Enrollee’s current sewer system use ordinances, service agreements and/or other legally binding procedures to demonstrate the Enrollee possesses the necessary legal authority to:
• Prevent illicit discharges into its sanitary sewer system from inflow and infiltration (I&I); unauthorized stormwater; chemical dumping; unauthorized debris; roots; fats, oils, and grease; and trash, including rags and other debris that may cause blockages; • Collaborate with storm sewer agencies to coordinate emergency spill responses, ensure access to storm sewer systems during spill events, and prevent unintentional cross connections of sanitary sewer infrastructure to storm sewer infrastructure; • Require that sewer system components and connections be properly designed and constructed;
• Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee;
• Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures; and
• Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

COMPLIANCE
The above items are addressed in order below:
a. Authority to prevent illicit discharges into the City’s wastewater collection system.

Title 6, Chapter 5, Article 2 of the City’s Ordinance Code regulates the disposal of sanitary sewage into the City’s sanitary sewer system to protect the proper functioning of the collection system as well as the treatment plant. Chapter 5 includes, but is not limited to the following key provisions:
• §6-5.208: General and specific prohibited discharge standards (includes, but is not limited to, prohibitions for storm water, obstructing or injurious substances, flammable or explosive substances, hot substances, FOG, solid or viscous matter, corrosive matter, toxic gases, vapors, or fumes, interfering substances, prohibition on use of diluting waters, suspended solids; dissolved matter, noxious or malodorous matter, radioactive matter, colored matter, garbage, and non-flushable wipes).
• §6-5.209: Pretreatment local limits.
b. The City’s pre-planned collaboration and coordination with storm drain agencies.

The City owns and operates most of the storm drains within its boundaries and has a de facto legal authority to ensure access to these storm drains in the event of a wastewater spill. In addition, both Sutter County and Caltrans own and operate some storm drains and/or storm water retention basins within the City. The City will coordinate with Caltrans and Sutter County to prepare mutual aid agreements to allow the City to respond to any wastewater spills which enter a Caltrans or Sutter County storm drain or retention basin. The City does not currently possess a reliable mapping system for storm drains.

LEGAL AUTHORITY
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 28 of 69 c. Require that sewer system components and connections be properly designed and constructed.

Title 6, Chapter 5, Article 3, Section 6-5.301(b) of the City’s Ordinance Code states that “the design and construction of building sewers and service laterals, including the connections, shall be in accordance with the requirements of the City, latest edition of the International Building Code and California Plumbing Code, and in accordance with the City's standard specifications.” Article 3 includes provisions related to testing, maintenance and repair, requirements for plans, specifications, persons authorized to perform work, and design standards for sanitary sewers, construction inspections.

The City’s standard specifications are found on the City’s website on the Engineering’s Technical Documents page.
d. Ensure access for maintenance, inspection, and/or repairs for portions of the service lateral owned and/or operated by the Enrollee.

Title 6, Chapter 5, Article 2, Section 6-5.206 of the City’s Ordinance Code states that all service laterals are installed, properly maintained, and repaired by the owner of the property that the lateral serves.

However, Title 6, Chapter 5, Article 3, Section 6-5.301(h) states, in part, “The City shall have the right to conduct maintenance inspection, and/or repair to the service lateral if needed, and it shall be the property owner's obligation to reimburse the City for the actual cost of such repair and inspection.” e. Enforce any violation of its sewer ordinances, service agreements, or other legally binding procedures.

The authority to enforce the sewer ordinance is found in Chapter 5, Article 1 of the City’s Ordinance Code. Section 6-5.103 describes the City Manager’s authority to coordinate enforcement actions of the Public Works Director, the Finance Director, and any other necessary department. Primary enforcement authority is assigned to the Public Works Director. The overall enforcement policy and penalty provisions for violations of the City’s Ordinance Code is found in Chapter 2. f. Obtain easement accessibility agreements for locations requiring sewer system operations and maintenance, as applicable.

Title 6, Chapter 5, Article 2, Section 6-5.223 of the City’s Ordinance Code, states “The City shall have the right to operate, inspect, maintain, and repair sewer system assets located within the sewer easements.” Title 6, Chapter 5, Article 3, Section 6-5.302(e) states that “in the event an easement is required for the extension of the public sewer or the making of connections, the applicant shall procure and have accepted by the City a proper easement or grant of right-of-way having a minimum width sufficient by law to allow the laying and maintenance of such extension or connection.” Some manholes are in backyards in the older part of town; however, the City has easements allowing for access. The City has exposed about 85% of these areas and has completed CCTV inspections. The City maintains a binder containing information for each backyard where work has been performed (i.e., manhole brought to grade, cleaned). The City will continue this work for the remainder of the backyard manholes.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Are the City ordinances and standards adequate for fulfilling the SSMP legal requirements? • Does the City have a process in place for periodic review and evaluation of ordinances? • Have there been instances when the code or ordinance did not address a need or circumstance?

4. Operation and Maintenance Program

WDR REQUIREMENTS
Att. D-4 (pg. D-4)
“The Plan must include the items listed below that are appropriate and applicable to the Enrollee’s system.”

4.1. Updated Map of Sewer System

WDR REQUIREMENTS
Att. D-4.1 (pg. D-4)
“An up-to-date map(s) of the sanitary sewer system, and procedures for maintaining and providing State and Regional Water Board staff access to the map(s). The map(s) must show gravity line segments and manholes, pumping facilities, pressure pipes and valves, and applicable stormwater conveyance facilities within the sewer system service area boundaries.”

COMPLIANCE
The City GIS system and associated databases, including iWorQ, show locations and list attributes of gravity pipelines, maintenance structures (manholes), pressure lines and valves, pumping facilities, and applicable stormwater conveyance systems.

The mapping system includes a sanitary sewer collection system grid map for preventative maintenance activities. There are a total of 144 grids covering the entire sewer collection system. Gilsizer Slough and Live Oak Canal, which are located close to major collection trunk lines, are also shown on the GIS maps.

The mapping system allows City staff to locate the collection system components and relevant features electronically (e.g., city streets, highways, critical structures, local waterways, city limits, addresses, and property tax roll data).

The GIS maps are available to the sewer maintenance field staff at the Corporation Yard electronically. The GIS data and maps are also accessible on the computers used for the high-pressure hydraulic jet cleaning and combination vacuum trucks and the CCTV truck. The maps serve as an aid to engineers in planning improvements and for the maintenance crews in locating various items in the field.

The last comprehensive update to the GIS maps was completed in approximately 2009. The City's Information Technology Division maintains the City GIS system including sanitary sewer collection system maps. As-built elements of the collection system are periodically added to the GIS system. A consulting firm is currently updating some GIS layers as part of a long-term project to update the maps for the entire City’s wastewater, water, and stormwater systems. Sewer mains were moved out of backyards and replaced in the downtown area from 2012-2014. The as-built drawings from this project are anticipated to be incorporated into the City’s GIS system by the end of 2025.

City staff intend to implement a process to keep maps up to date, including (1) Contracting for professional services to update map layers for wastewater, water, and stormwater soon after as-built drawings are completed for new subdivisions and other developments, and 2) Developing staff capacity or contracting for professional services to correct maps when staff identifies errors or omissions.

Upon request, the City will provide State and Regional Water Board staff a link to system maps.

4.2. Preventive Operation and Maintenance Activities

WDR REQUIREMENTS
Att. D-4.2 (pgs. D-4/D-5)
”A scheduling system and a data collection system for preventive operation and maintenance activities conducted by staff and contractors. The scheduling system must include:
• Inspection and maintenance activities;
• Higher-frequency inspections and maintenance of known problem areas, including areas with tree root problems;
• Regular visual and closed-circuit television (CCTV) inspections of manholes and sewer pipes.

The data collection system must document data from system inspection and maintenance activities, including system areas/components prone to root-intrusion potentially resulting in system backup and/or failure.”

COMPLIANCE
The purpose of a work order system is to program and track all required inspection and maintenance activities within the collection system to help proactively prevent blockages/operational problems or spills.

The City utilizes the iWorQ software which is geared toward community development and public works departments. This web-based software allows City staff to access data from a tablet or smart phone while in the field. The City’s GIS system is integrated into iWorQ.

The City’s software program maintains historical data for all maintenance activities and provides a basis for critical analysis and data-driven planning and decision-making today and into the future. This allows for prioritizing and planning routine activities such as CCTV inspections, pipe cleaning, and chemical root control.

The City does not use iWorQ to create work orders. Instead, City staff use the maps found within iWorQ to visually show when a section of the collection system was last cleaned or CCTV inspected. City staff start at the “top” of the collection system and clean/inspect their way to the “bottom”. After work is completed each day, staff document their work by entering the results in iWorQ. This changes the colors of the asset on the map and allows staff to visually see where to begin work the next day.

The City maintains a list of Hot Spots which are cleaned quarterly. This information is entered into iWorQ, as well as emergency and other reactive activities. Work orders for other activities are generated by supervisory personnel on an as-needed basis.

The City’s preventative maintenance work order tracking has improved significantly in the last few years by using facility identification numbers for work orders and by checking the consistency of documentation of preventative maintenance activities.

4.3. Training

WDR REQUIREMENTS
Att. D-4.3 (pg. D-5)
“In-house and external training provided on a regular basis for sanitary sewer system operations and maintenance staff and contractors. The training must cover:
• The requirements of this General Order;
• The Enrollee’s Spill Emergency Response Plan procedures and practice drills; • Skilled estimation of spill volume for field operators; and • Electronic CIWQS reporting procedures for staff submitting data.”

COMPLIANCE
The City’s training program covers several areas associated with wastewater collection systems and serves to develop and maintain highly qualified, knowledgeable, and capable staff. This training is provided through a variety of modes and begins with the first day on the job and continues regularly thereafter.

Most of the on-the-job training and skill related training occurs when new employees work closely with more experienced staff to become familiar with the City facilities and their mechanical, electrical, and control systems.

Operational training occurs when the Wastewater Collections Supervisor directs the O&M activities for the sewer collection system (excluding lift stations) during normal and high-flow events and the WWTF Plant Maintenance Supervisor directs O&M activities for lift stations during normal and high-flow events. Current operational training for supervisors occurs through one-on-one mentoring at the supervisory level.

The City provides safety training to the O&M staff that meets California Occupational Health and Safety Administration (CalOSHA) personnel safety and awareness requirements (e.g., confined space entries, lockout/tagout, etc.) on a continuous basis. Training sessions for Health and Safety items are documented using a training matrix and records are maintained using a training software program. The Training materials are stored at the WWTF and at the Corporation Yard depending on the type of equipment/facility.

In addition, O&M staff receive training provided by equipment suppliers and vendors when new facilities are constructed.

However, training sessions that are more applicable to the collection system, such as implementing the Spill Emergency Response Plan (SERP) and CIWQS data submittal, have not been offered on a regular basis and have not been documented. Moving forward, the City is committed to investing in a regular, documented training program. A sample training record is included in Appendix 4.

The City typically has the resources and staff available to operate and maintain the collection system and does not employ private contractors. However, the City uses private contractor’s help as needed for backup support in case of equipment failure. Contractors are always accompanied by trained City staff who are responsible for coordinating and directing the contractors during a spill event, and for following all appropriate procedures. The City does not allow private contractors to work on a spill without the presence of City staff. However, if contractors will work by themselves and therefore need training, the City will use the “Spill Response Requirements for Contracted Services” form found in Appendix 4.

OPERATIONS AND MAINTENANCE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 35 of 69 Staff involved in responding to sewage spills have previously received training on the City’s SERP and the requirements of the WDR. However, because there have been very few spills City staff have not implemented their training. The City intends to offer more frequent training related to the SERP, including both classroom and hands-on exercises and drills. The training is intended to cover containment, restoring flow, estimating spill volume and volume recovered, spill start time estimations, clean up and completing the spill event data collection forms.

Staff designated as Data Submitters have been trained on the City’s procedures for reporting spills from receipt of call to draft report submittals and certification. Data Submitters and other City staff would benefit from additional spill response training.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Has all training been completed as scheduled?
• Have records of training and attendance been documented and maintained? • Have all staff demonstrated ability and knowledge after each training event? • Have contractors received, at a minimum, direction for reporting and responding to spills?

4.4. Equipment Inventory

WDR REQUIREMENTS
Att. D-4.4 (pg. D-5)
“An inventory of sewer system equipment, including the identification of critical replacement and spare parts.”

COMPLIANCE
The City maintains a host of equipment for both routine maintenance and for contingency or emergency operations. The required sewer line repair parts (such as manhole covers, pipe repair parts etc.). are stored at the Corporation Yard and lift station parts (such as pumps, electrical parts, etc.) are stored at the WWTF.

The inventory of replacement parts is controlled by the assigned criticality of the part. The parts with high criticality have a higher stocking priority and inventory backlog to appropriately respond to an emergency.

Three lift stations, Lift Stations #1, #2, and #10, have permanent on-site generators. The onsite permanent generators supply power to these lift stations during a power outage. Two more permanent onsite generators have been purchased and installed for Lift Stations #3 and #14. Portable generators are stored at both the Corporation Yard and the WWTF to be available to provide temporary power at all other lift stations.

The City purchases replacement and spare parts in advance and tracks these items in its inventory. The Wastewater Collections Supervisor and WWTF Plant Maintenance Supervisor determine which parts need to be stored at their respective facilities. As these items are used, replacement parts are ordered. The following paragraphs describe where different major items like pumps and generators are located or stored.

It also discusses where replacement and repair parts are located and how inventories are maintained. An example inventory list for the sewer mains, Stonegate, spill response, and lift stations is found in Appendix

4. Corporation Yard: Sewer Mains and Stonegate System
Pipe and fittings for sewer line repairs and all replacement and repair parts associated with the Stonegate STEP systems are stored at the Corporation Yard. Sewer crews maintain sewer mains and respond to emergencies throughout the City as scheduled and as needed. At Stonegate, sewer crews replace the pumps, valves, bio baskets, and inspect the associated electrical and mechanical equipment for each home on a two-year rotation and respond to emergencies as needed. The Sewer System Supervisor tracks the inventory and ensures equipment and supplies are ordered as needed to maintain adequate inventories.

Spill Response Equipment
Most equipment needed for responding to Sanitary Sewer Spills is stored at the Corporation Yard.

Additional equipment is stored at the WWTF.

Lift Stations
Lift station equipment and parts are stored at the WWTF Maintenance shop and warehouse. At least one spare pump is on hand for emergency replacement of any Flygt pump in the 16 lift stations running on Flygt pumps. Rebuild kits are also kept on hand for these pumps. Normal practice is to rebuild or replace any pump immediately when a pump is taken out of service for repair. Rebuild kits are also ordered whenever a kit is used for a pump rebuild. Pump and parts inventories are updated and reported to Finance every year. The Maintenance Supervisor and Lead Mechanic are responsible for tracking inventory over the course of the year and making sure the spare pumps, rebuild kits, and various repair parts are replaced as needed.

Lift Station #10 has three 30 HP pumps installed and is never allowed to run more than two at any time.

There isn’t a 30 HP Flygt pump in storage for this lift station. If one pump needs to be taken out of service, normal practice is to run on the remaining two. A spare 10 HP pump is available for temporary operation if needed.

WDR REQUIREMENTS
Specification. 5.19 (pg. 27)
“To prevent discharges to the environment, the Enrollee shall maintain in good working order, and operate as designed, any facility or treatment and control system designed to contain sewage and convey it to a treatment plant.”

COMPLIANCE
The City’s sanitary sewer collection system consists of approximately 173 miles of gravity sewer lines ranging from 4 inches to 54 inches in diameter, approximately 3.3 miles of force-main ranging from 4 inches to 20 inches in diameter and 17 lift stations. Approximately 70 percent of the collection system gravity mains are 6-inch and 8-inch diameter lines. This has a direct impact on the sewer pipeline maintenance activities and the equipment needed to maintain the collection system.

Regular Maintenance and Cleaning
Routine preventive O&M activities are performed by a sewer maintenance staff consisting of five journey level (greater than two years of experience) people and one entry level person under the direction of the Wastewater Collections Supervisor. The major equipment for routine preventive O&M activities includes:
two combination jet-vacuum trucks, an easement jetter, one CCTV truck, a mini-excavator, and a dump trailer.

Pipeline cleaning of the sanitary sewer system is routinely accomplished on a grid basis. A grid is selected and cleaned by one of the sewer maintenance crews with the city-owned combination jet cleaning and vacuum truck. The work is documented using the iWorQ computerized maintenance management system (CMMS) sewer software.

The cleaning is performed from top to bottom of a grid, moving downstream from the upper reaches of the grid down to the collector sewers and trunk pipelines. Once a crew is assigned a grid, they continue working in the assigned grid until all the pipelines are cleaned. Progress slows down when the crews get into the older areas of the community which require much more work. The goal is to clean the whole collection system once every four years; the collections crew have been averaging between 2,500 and 5,500 linear feet per day for the past several years.

The CCTV crew follows behind the cleaning trucks, inspecting the pipelines that have been recently cleaned.

Thus, all the pipeline cleaning work is inspected. Through this approach, if the CCTV crew encounters a pipeline where additional cleaning is needed, the CCTV crew calls the cleaning crew and has them complete the pipeline cleaning before they move on. In cases where there may be a need for pipe repair or replacement, the CCTV footage is referred to the Engineering Division for further assessment.

Computer based software (GraniteNet/GNET) is utilized by the crews through laptop computers used by combination cleaning truck and through the onboard computer in the CCTV inspection truck. The videos from the CCTV truck computer are stored on a dedicated computer drive for record-keeping purposes and for evaluations of rehabilitation work.

All crew members are National Association of Sewer Service Companies (NASSCO) Pipeline Assessment Certification Program (PACP) trained and certified operators. The pipeline cleaning, inspection, and maintenance crews also serve as first responders to collection system blockages and/or spills.

The cleaning crews do not routinely document their inspection of manholes. However, the City intends to do so in the future, using a form such as the example “Manhole Inspection Form” found in Appendix 4.

OPERATIONS AND MAINTENANCE PROGRAM

In addition to the routine preventative maintenance activities, higher frequency cleaning and inspection is scheduled for pre-selected pipelines where history has shown that grease or debris will cause sewer backups or spills unless these pipelines are cleaned more frequently. A list of these pipelines is shown in the table below. These pipelines are scheduled to be cleaned quarterly and inspected once every year. Most of the problems with these pipelines are believed to be related to sags or "flat bellies" that can be scheduled for repair or replacement in the relatively near term.

The Sewer Collections team's goal is to conduct CCTV inspections of the entire system over a six-year period.

The City conducts its CCTV inspections using a truck outfitted with GraniteNet/GNET software. The system is NASSCO Pipeline Assessment Certification Program compliant. A pipe condition rating system is included with GraniteNet/GNET. The Engineering Division has a version of GraniteNet/GNET as well.

When the CCTV truck comes into the Corporation Yard at the end of the shift, the data is uploaded as the truck drives into its parking bay. The data is then transferred to the Engineering Division where the data is reviewed.

If a significant defect or possible sewer failure is found during an inspection, the crew will either contact the Wastewater Collections Supervisor and have him or her review the data in the truck or download an electronic copy onto a flash drive for viewing.

Root Control
Root control is contracted out to Duke’s, a firm that specializes in root control in sanitary sewer systems.

This is another key piece of the City's efforts to minimize or eliminate problems that could lead to a sewer blockage or spill. The City has been contracting out about three miles per year of sewer pipeline to Duke's, focusing on the old town backyard sewers. Duke's applies Razorooter II, diquat-based herbicide, using a foam that covers roots with the herbicide.

Duke's has over 40 years of experience with root-control in sanitary sewer systems and guarantees that their treatment will remove the roots in the pipelines where the herbicide is applied for one year after application. The City has Duke's crews apply the herbicide between April and May. After the application, the City will use the CCTV inspection truck and equipment to inspect the treated line multiple times to confirm that the herbicide was effective in killing the roots.

In Yuba City, most root problems are in backyard easements. The City tries to avoid jetting the lines that have been foamed to minimize damage to pipes but will do so on occasion if needed. The City's experience has been that the worst root intrusion conditions will occur after a wet winter followed by a hot summer.

The City crews use RootX for isolated root intrusion problems.

Lift Stations
In addition to the gravity pipeline network, the City owns, operates, and maintains 17 sewer lift stations.

These pumping stations lift the wastewater flowing in deeper sewers to higher pipelines so that the sewers do not get excessively deep. Deep sewers are more costly to construct and harder to maintain. The table at the end of this section summarizes the available information regarding the location, construction history, and operating characteristics of each station.

Thirteen of the lift stations (#1, #2, #3, #4, #5, #7, #9, #10, #11, #12, #13, and #15) have full SCADA control from the WWTF through 5G cellular communications. Four lift stations (#6, #14, #16, and #17) use radio signals for monitoring and control on SCADA. The remaining lift station, #8, is solely monitored indirectly, using a SmartCover sensor installed at manhole upstream of the lift station.

The SCADA system at the WWTF is monitored 24/7 and operational adjustments can be made from the WWTF for each lift station. SCADA communications provide information on wet well levels, pump run status, and operational setpoints. The City is currently working to install cellular communications at all lift stations, then plans to incorporate the SCADA system into the cellular communications system.

Five of the City's six stormwater detention basins are also connected to the WWTF's SCADA system which is monitored during storm events.

A key component of the City's efforts to minimize or eliminate sewer blockage or spill problems is the use of SmartCover Monitoring and Alarm Systems. SmartCovers provide real-time satellite manhole monitoring

OPERATIONS AND MAINTENANCE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 41 of 69 and alerts of rising water levels which allows managers and operators to dispatch sewer crews to address problems before spills occur.

Following a large sanitary sewer spill occurred in 2014, the City installed SmartCovers upstream of all the lift stations which were not monitored by the SCADA system at that time. The City now has SCADA monitoring at most lift stations and has continued to increase the number of SmartCover monitoring sites as a backup alarm system and for flow monitoring at some sites.

Eighteen SmartCover monitoring units have been installed at strategic locations throughout the collections system. Most of the SmartCovers are in manholes immediately upstream of a lift station. In addition to level monitoring, SmartCovers at Lift Stations #2, #3, and #11 had flow monitoring capability as of June 2025. The SmartCovers have allowed sewer crews to identify and clear many sewer blockages before they resulted in spills.

The two main lift stations, Lift Stations #2 and #10, had historical issues with odors and problems with FOG building up in the wet wells. Therefore, the City installed ozone units that spray a mist on top of the scum and FOG blanket at Lift #10, and spray directly into the sewage solution at Lift #2. This helps keep FOG from building up in the wet wells, minimizes odor problems, and lowers chemical costs at the WWTF.

City wastewater maintenance staff conducts an on-site physical inspection of each lift station every week.

City staff also undertake an assessment of lift station maintenance needs once/month. Approximately quarterly, the crew removes grease ring buildup and vacuum up debris. Six or seven of the lift stations have occasional grease ring buildup of 5 to 6 inches per month. The crews remove grease off walls with high pressure jet spray and clean the remaining wet wells to remove grease rings once per month. Two lift stations (#2 and #10) are on a higher frequency for cleaning.

Permanent emergency generators are currently installed at Lift Stations #1, #2 and #10. Two new standby permanent generators have been purchased and are now functional at Lift Stations #3 and #14. Generator hookups have been installed at all 17 lift stations and portable emergency generators are available for power failures. Bypass fittings and valves have been installed at Lift #2 to make bypass pumping easier to set up.

The City has a binder titled “S.O.P. for Lift Station Failures, 2017” which specifies the procedures needed to set up a bypass for each lift station. This binder also contains standard procedures for cleaning and maintenance of each lift station, as well as specific things to be aware of (i.e., be aware of overhead lines, avoid during school traffic hours). Operations staff plan to update this binder to include Emergency Response Plans for each lift station.

“Procedures, and standards for the inspection and testing of newly constructed, newly installed, repaired, and rehabilitated system pipelines, pumps, and other equipment and appurtenances.”

COMPLIANCE
Article 3 Section 6-5.304 of the City's sewer ordinance describes inspection requirements. The City's Construction Inspector conducts the inspections for all the sewer system construction work to ensure compliance with City requirements. The City will not accept any construction work which is covered/buried before inspection and approval has occurred. Typically, the City assigns a Construction Inspector to specific construction project(s). The Construction Inspector coordinates with the City's Resident Engineer and Construction Manager to resolve issues related to the construction during the construction period.

Generally, the testing includes a water pressure test, an airtest, and CCTV inspection. The City accepts the completed work only if all the required testing is completed to the satisfaction of the Resident Engineer and in conformance with the industry standards. Pump stations are also tested before final acceptance. The City requires a 1-year warranty to correct any defective construction work.

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 49 of 69

7. Sewer Pipe Blockage Program

WDR REQUIREMENTS
Attachment D-7 (pg. D-7)
“The Sewer System Management Plan must include procedures for the evaluation of the Enrollee’s service area to determine whether a sewer pipe blockage control program is needed to control fats, oils, grease, rags and debris. If the Enrollee determines that a program is not needed, the Enrollee shall provide justification in its Plan for why a program is not needed.

The procedures must include, at minimum:
• An implementation plan and schedule for a public education and outreach program that promotes proper disposal of pipe-blocking substances;
• A plan and schedule for the disposal of pipe-blocking substances generated within the sanitary sewer system service area. This may include a list of acceptable disposal facilities and/or additional facilities needed to adequately dispose of substances generated within a sanitary sewer system service area;
• The legal authority to prohibit discharges to the system and identify measures to prevent spills and blockages.
• Requirements to install grease removal devices (such as traps or interceptors), design standards for the removal devices, maintenance requirements, best management practices requirements, recordkeeping and reporting requirements; • Authority to inspect grease producing facilities, enforcement authorities, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An identification of sanitary sewer system sections subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each section; and • Implementation of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each section identified above.”

COMPLIANCE
During 2008, the City experienced 15 sanitary sewer overflows. Ten of these resulted from grease blockages, five times more than from any other single source. Since FOG is a significant component of the wastewater generated by food service establishments (FSEs), they are an obvious target for source control measures to reduce spills. The City implemented a FOG control program in 2008 and since then has encouraged FSEs to install and properly maintain grease removal devices.

The requirements above are addressed in order below:
a. Public Outreach. The Public Works Department participates in various public outreach events each year, including posting videos on social media and attending the Yuba Sutter County Fair where Department staff hand out various educational brochures and promotional items. FOG educational materials which are distributed include literature aimed at residential customers on the proper disposal of fats, oils and grease. Pan scrapers are distributed to remove food, oils, and grease from cooking pans and dishes before cleansing and washing. Lid covers are distributed to encourage residents to pour their oil and grease into a can to cool it before disposing of it in the trash.

The Public Works Department outreach program also includes developing new educational brochures. The Department has several brochures that target FSEs and commercial businesses. The Department also intends to create educational door hangers for the City's residents. Department staff

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 50 of 69 will target providing these door hangers to residential neighborhoods where there are known FOG high-frequency cleaning pipelines in the collection system.

The City’s website includes a page titled Fats Oils and Grease which includes examples of FOG, describes why it is a problem, and provides tips for disposal. In addition, the City’s utility trucks have large magnet stickers on the side, showing pictures of what not to flush into the sewer system. b. Disposal. FOG which is generated by FSEs is collected in grease interceptors or grease traps which are maintained by the FSEs. The FOG that is accumulated is pumped out by licensed grease haulers hired by the FSEs and taken to a location that accepts inedible kitchen grease. The licensed grease haulers provide monthly pump-out records to the City. The City's Environmental Compliance Coordinator monitors the frequency of pump-outs by using the ACP FOG web-based software.

The Sewer Collections crew removes FOG that is generated in the collection system during their routine maintenance of pipes and lift stations. The grease removed from the collection system is disposed of at the City's WWTF.
c. Legal authority to prohibit discharges. The City’s legal authority is found in Title 6, Chapter 5, Article 12 of the City’s Municipal Code. Section 6-5.1202.b states "No FSE shall discharge FOG or cause FOG to be discharged into the public sewer that causes an SSS, exceeds a concentration level set forth in Section 6-5.208, or that may accumulate and/or cause or contribute to blockages in the public sewer."
In addition, Title 6, Chapter 5, Article 2, 6-5.208 of the City’s Ordinance Code regulates the disposal of sanitary sewage into the City’s sanitary sewer system to protect the proper functioning of the collection system.
d. Requirement to install grease interceptors, design standards, etc. Sections 6-5.1201 through 6-

5.1209 of Title 6, Chapter 5, Article 12 of the City’s Municipal Code require the installation of grease interceptors or grease traps. These sections also set forth design standards that conform with the most recent California Plumbing Code, as well as maintenance requirements, best management practices requirements, record keeping, and reporting requirements. e. Authority to inspect and enforce. Section 6-5.1206(a) of Title 6, Chapter 5, Article 12 of the City’s Municipal Code provides the authority for the Public Works Director or designee to inspect or order the inspection and sample of the wastewater discharges of any FSE to ascertain whether the FSE is complying with all requirements. The Ordinance states that the FSE shall allow the City access to the FSE premises during normal business hours for purposes of inspecting the FSE's grease removal devices and reviewing the manifests, receipts, and invoices relating to the cleaning, maintenance, and inspection of the grease removal device.

Section 6-5.1204 of Title 6, Chapter 5, Article 12 of the City’s Municipal Code Sewer pertains to system spills, public nuisance, abatement orders, and cleanup cost and notes that any excessive sewer maintenance expenses can be charged to the offending discharger by the City and any refusal to pay can constitute a violation of the ordinance.

Enforcement authority is found in Sec. 6-5.1209 of Title 6, Chapter 5, Article 12 of the City’s Municipal Code, and states "Failure on the part of any FSE to maintain continued compliance with any of the requirements set forth in Sections 6-5.1201 through Sections 6-5.1208 may result in the initiation of enforcement action, as outlined in Sections 6-5.1001- Sections 6-5.1003. Such enforcement action may include, but is not limited to, the issuance of a verbal warning, written warning, notice of violation (NOV), administrative order, administrative civil liability, and/or imposition of administrative fines and/or penalties."

SEWER PIPE BLOCKAGE PROGRAM
© 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 51 of 69 With respect to staffing, the City’s Environmental Compliance Coordinator reviews the development plans for all new construction and remodeling of FSE’s prior to issuance of a building permit. This ensures that the installation of a grease removal device is incorporated into the construction of the facility and that the City's requirements and design standards are being met. Until recently, the City assigned one full time staff person to inspect and enforce the FOG program, but that position is currently vacant. The City is working toward filling the position. f. FOG-related problem areas. Higher-frequency cleaning and inspection is scheduled for pipelines where history has shown that grease or debris will cause sewer backups or spills under the normal cleaning schedule (i.e., “hot spot list”). These pipelines are scheduled to be cleaned quarterly and are also scheduled for a CCTV inspection once every year. Some of the pipelines are on the highfrequency cleaning cycle due to sags or bellies in the pipelines. These pipelines must be rodded or cleaned using chain flails attached to the rotating high-pressure jet nozzles on the cleaning machines.

The majority of the pipelines on the high-frequency cleaning list are in residential areas that do not have any restaurants located in the same area. In these areas, the City has conducted outreach focused on FOG disposal practices in apartment complexes, multiplexes and single-family homes. g. Source control measures. The City uses its business database to develop and maintain a list of all FSEs. As of 2025, a total of 234 FSEs are included in the FOG control program, with 89% of those FSEs known to have grease removal devices in operation. The City utilizes the ACP FOG management software whichhas streamlined management of the FOG control program. The ACP FOG software is web-based, which enables staff to complete inspection reports while onsite. The City strives to inspect each FSE once per year. Through increased outreach, inspection, and enforcement, it is the City's goal to minimize discharges of FOG to the sanitary sewer system through the implementation of best management practices by FSEs and cooperation from the City residents. The City’s efforts have resulted in no spills or only one spill each year since 2015.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Have there been any blockages/spills from any identified problem area? • Is the City receiving feedback on public outreach efforts? • Are the debris and other sewage solids collected during cleaning activities being disposed of appropriately?
• Have there been spills due to excessive fats, oil, grease, roots, or non-dispersible wipes discovered in the sewer system during the audit period?
• Are there repeat offenders among FSEs?
• Are enforcement trends decreasing?
• Are Source Control and Collection staff included in the plan check process?

8.1. System Evaluation and Condition Assessment

WDR REQUIREMENTS
Attachment D-8.1 (pgs. D-7/D-8)
“The Plan must include procedures to:
• Evaluate the sanitary sewer system assets utilizing the best practices and technologies available;
• Identify and justify the amount (percentage) of its system for its condition to be assessed each year;
• Prioritize the condition assessment of system areas that:
• Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;

SYSTEM EVALUATION, CAPACITY ASSURANCE, CAPITAL IMPROVEMENTS © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 54 of 69

COMPLIANCE
The above requirements are addressed below:
a. The City’s collection system evaluation involves every component of the City collection system, including pipelines, manholes, and pump stations. The assessment of pipeline condition is the most significant condition assessment responsibility the City has. It is of key importance to regularly perform pipeline condition assessments to initially establish a baseline condition and to monitor changes over time. City staff assess the condition of laterals using push cameras and pole cameras which can be dropped into manholes. In addition, the City has 18 smart covers on manholes within the sewer line, most of which are upstream of a lift station. b. The City has historically cleaned the entire collection system on a four-year interval CCTV inspects the system on a five-year interval. The City believes the six-year inspection interval to be appropriate because most of the pipes are in good condition, with only 27 locations that receive quarterly cleaning (those locations on the hot spot list), the city cleans each line every three years, and the City has maintained a low spill rate. The City periodically reviews and evaluates its pipe performance and inspection/cleaning intervals and may adjust the schedule to a less-frequent interval. c. Several of the City’s lift stations are near surface waters. Both Lift Station #2 and #10 have spilled into Gilsizer Slough. Lift Station #10 is immediately adjacent to Gilsizer Slough and is not fenced. The City will evaluate security at all its lift stations and the need to prevent potential vandalism with a resulting environmental impact. The entire collection system is at least 3,000 feet from the City’s drinking water intake.
d. The City assesses system conditions using visual observation, video surveillance, smart covers on manholes, pole cameras, and CCTV camera service. The City’s collection system includes pipes which run through private backyards in the older part of town. This portion of the collection system is more susceptible to root intrusion and therefore the City prioritizes root control activities (herbicide application followed by inspection) in this area.
e. The City is currently not aware of any exiting of sewage from the collection system. The City actively inspects and maintains its collection system to prevent sewage from exiting and impacting the environment.
f. The City documents all inspections, maintenance, and evaluations of the sewer system. When the CCTV truck comes into the Corporation Yard at the end of the shift, the data is uploaded as the truck drives into its parking bay. The data is then transferred to the Engineering Division where the data is reviewed and used to prioritize future work. All documents are maintained at the City office or in the iWorQ program.
g. The City is immediately adjacent to the Feather River and downstream of the Oroville Dam.

Stormwater flows to large retention basins and is then pumped over the levee and into the Feather River or flows into one of several sloughs running through town. The City’s collection system is vulnerable to flooding in the event of a levee break, dam failure, or severe rain. The City participated in and will implement the 2021 Sutter County Local Hazard Mitigation Plan Update. In addition, the City will continuously monitor for change and review the potential impacts of climate change during each audit. If potential impacts are identified, appropriate action will be taken and the SSMP will be updated.

8.2. Capacity Assessment and Design Criteria

WDR REQUIREMENTS
Attachment D-8.2 (pgs. D-8/D-9)
“The Plan must include procedures to identify system components that are experiencing or contributing to spills caused by hydraulic deficiency and/or limited capacity, including procedures to identify the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow conditions that cause or contributes to spill events; • The appropriate design storm(s) or wet weather events that causes or contributes to spill events.
• The capacity of key system components; and
• Identify the major sources that contribute to the peak flows associated with sewer spills.

The capacity assessment must consider:
• Data from existing system condition assessments, system inspections, system audits, spill history, and other available information;
• Capacity of flood-prone systems subject to increased infiltration and inflow, under normal local and regional storm conditions;
• Capacity of systems subject to increased infiltration and inflow due to larger and/or higherintensity storm events as a result of climate change; • Increases of erosive forces in canyons and streams near underground and above-ground system components due to larger and/or higher-intensity storm events; • Capacity of major system elements to accommodate dry weather peak flow conditions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacities.”

COMPLIANCE
The City hired West Yost Associates to develop the 2020 Wastewater Master Plan for both the collection system and the WWTF. The Master Plan projected dry and wet weather scenarios with a hydraulic model using lnnovyze® lnfoSewer™ software that allows for a time-varying flow analysis of dry weather and peak wet weather conditions.

While the 2006 hydraulic model analyzed trunk sewer lines that were 12" in diameter or larger, small diameter gravity mains that were not previously included in the hydraulic model were added to the new model as part of the 2020 model update. The City’s GIS database was used to populate the model with the previously unmodeled lines.

The gravity line analysis found that 44 modeled manhole-to-manhole segments totaling approximately 11,000 lineal feet of pipe ranging from 8- inches to 36-inches in diameter exceeded the performance criteria developed for existing peak hourly wet weather flow conditions design conditions. However, the model results indicate the exceedances in question all produced minimal surcharging (<1 foot). It was therefore concluded that no capacity improvements to existing gravity mains were required and that no sanitary sewer spills were expected in the near future.

The hydraulic model also determined that of the existing collection system lift stations, only lift station #9 and lift station #10 have insufficient firm capacity to convey existing modeled peak flows. Due to the different options being considered for expanding the capacity of the collection system, it was recommended

SYSTEM EVALUATION, CAPACITY ASSURANCE, CAPITAL IMPROVEMENTS © 2025 Fischer Compliance, LLC. All rights reserved. Sewer System Management Plan licensed for Yuba City use only. Page 57 of 69 that any capacity improvements to these lift stations be evaluated within the context of future development.

While not included as part of the Wastewater Master Plan, the numerous extreme storms that pummeled Northern California during the 2022 - 2023 wet season did not result in any wet weather sewer spills in Yuba City. This seemed to confirm the results of the existing conditions modeling.

Modeling for the future first considered buildout capacity needs, as these needs influence what is required for near-term development. While different scenarios were analyzed, the hydraulic evaluation of four different buildout flow scenarios concluded that there were no significant differences among the collection system modeling results.

The Master Plan includes the typical design criteria for new sanitary sewer system design. The capacity analysis of the existing system was conducted using typical design criteria. The flow assumptions in the design criteria include an allowance for development density, flow per unit, and I&I contributions. The design criteria and the flow assumptions will be refined through future flow monitoring as needed.

In FY 2024 -2025, the City contracted with West Yost to update the hydraulic model upon which the Master Plan was developed.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:

The 2020 Wastewater Master Plan includes a Capital Improvement Program (CIP) which recommends projects to address system improvements regardless of an increase in service area population. With respect to the collection system, (a) gravity main and manhole condition-related improvements (non-capacity related) total $49.7 million over a 20-year period and (b) lift station condition and capacity-related improvements total $32.5 million over a 20-year period.

The Master Plan also includes a CIP to address future growth. For the near-term improvements, the total estimated capital cost is approximately $115 million. For buildout conditions, the total estimated capital cost ranges from approximately $174 million to $209 million.

The City relies on itsMaster Plan to plan for future growth, to secure needed funding, and to prioritize projects based on the City's development needs. The Master Plan identified alternatives to expand the City's sewer collection system (including lift stations) to accommodate the new growth. The City updates the Hydraulic Model as needed. As stated previously, the City has not identified any portions of the sewer collection system that are currently experiencing or contributing to a sanitary sewer discharge caused by hydraulic deficiency.

Capacity enhancement projects are completed through the short term (5 year) CIP and use the Master Plan as a road map for longer term planning for intervals up to 20 years. As part of the Capital Improvement Program, projections are prepared to determine the future funding requirements.

The City’s Adopted CIP Budget for FY2022-2027 includes numerous categories of projects, including for wastewater (starting at page 90). The CIP list shows the project start and completion dates by fiscal year. Typically, the projects are funded using the City's CIP project reserves, existing rates, SRF loans and bond financing. New customers pay for CIP projects through the current connection fee. The GIP project list splits the cost of each individual project among existing and new customers based on the project benefitsto existing and new customers.

Technical evaluations were prepared to ensure that the projects meet the design standards, the City's needs and other related requirements. The GIP projects were finalized based on the technical evaluations and are scheduled for design and construction.

The table below includes collection-system related capital improvement projects completed in the last five years and those planned for the next five years.

9. Monitoring, Measurement, and Program Modifications

WDR REQUIREMENTS
Attachment D-9 (pg. D-9)
“The Plan must include an Adaptive Management section that addresses Plan-implementation effectiveness and the steps for necessary Plan improvement, including:
• Maintaining relevant information, including audit findings, to establish and prioritize appropriate Plan activities;
• Monitoring the implementation and measuring the effectiveness of each Plan element; • Assessing the success of the preventive operation and maintenance activities; • Updating Plan procedures and activities, as appropriate, based on results of monitoring and performance evaluations; and
• Identifying and illustrating spill trends, including spill frequency, locations, and estimated volumes.”

COMPLIANCE
The above requirements are addressed below:
a. The City maintains accurate and relevant inspection and maintenance records for the collection system, including field data such as pipe cleaning and inspection frequencies, FSE inspections, and information regarding spills. Much of the documentation is maintained electronically, which allows for ease of access and analysis. This helps City staff to make sound decisions and prioritize activities when dealing with the routine and the unexpected. Monitoring of the City’s SSMP focuses on each element in terms of its implementation and effectiveness. The SSMP has been designed to include key performance indicators for each element, which are used to measure effectiveness. In addition, implementation responsibilities are included for each element to help ensure the SSMP is being implemented as intended.
b. The City assesses the success of maintenance and operation activities by analyzing the monitoring data and trends to measure the effectiveness of each element of the SSMP. Changes can and are readily made to the planned work as needed to address higher priorities in the collection system.
c. The City is committed to continuous improvement and monitors and evaluates performance of work programs and SSMP elements to ensure intended outcomes are achieved while looking for areas for improvement. Although the SWRCB requires that the SSMP be updated every six years, the SSMP is considered as a dynamic document and may require updating on a more frequent basis. Routine changes to administrative information, notwithstanding, minor changes will likely be required to address improvements identified through the SSMP Audit or through modifications required as conditions change.
d. The City monitors spill trends, at a minimum every three years during required audits, utilizing the CMMS database, inspection records and CIWQS data. These resources are helpful in planning and programing work, and adjusting as needed, enabling the City to be adaptive and capitalize on lessons learned.

10. Internal Audits

WDR REQUIREMENTS
Attachment D-10 (pg. D-10)
“The Plan shall include internal audit procedures, appropriate to the size and performance of the system, for the Enrollee to comply with section 5.4 (Sewer System Management Plan Audits) of this General Order.”

COMPLIANCE
The City submitted its most recent audit in compliance with the February 2, 2025, deadline and will complete audits every three years moving forward. The objective of the audit is to evaluate compliance, implementation and effectiveness of the SSMP. Additionally, the SSMP includes a description of how the City will comply with the requirements of each Element. The audit review includes an evaluation to determine if compliance has been met. A list of priority improvement opportunities will be prepared and updated as part of the audit program. Improvement opportunities will be used to prioritize and develop program modifications and will be initiated based on the priority and the available funding. An overview of SSMP related work completed between audits will be included in the program audits.

The Sewer Collections Division will perform periodic internal audits to determine the effectiveness of each element of the SSMP and will generate system metrics on an annual basis for the purpose of tracking, monitoring and adjusting the performance of the SSMP activities. The primary focus in the evaluation of system metrics will be the elimination of preventable spills and reduction of the impact of those spills that do occur.

Implementation is evaluated by determining if the City is executing the SSMP as stated.

Effectiveness is evaluated by using key performance indicators, which have been developed specifically for each element. An additional evaluation is performed to comply with Specifications 5.6 addressing resilience.

Resilience indicators have been developed for each element. These indicators serve to demonstrate how resilience is built into the SSMP and inspection, maintenance and spill response activities (see Appendix 12).

Any deficiencies discovered through the audit process are noted and a plan and schedule to implement corrective measures are established.

EFFECTIVENESS
The City utilizes the following Key Performance Indicators for measuring effectiveness of this Element:
• Have audits been performed as required?
• Have the audits assessed compliance, implementation, and effectiveness? • Have deficiencies been identified?
• Has a plan and schedule to rectify the deficiencies been established?

11. Communication Program

WDR REQUIREMENTS
Attachment D-11 (pg. D-10)
“The Plan must include procedures for the Enrollee to communicate with:
• The public for:
• Spills and discharges resulting in closures of public areas, or that enter a source of drinking water; and
• The development, implementation, and update of its Plan, including opportunities for public input to Plan implementation and updates.
• Owners/operators of systems that connect into the Enrollee’s system, including satellite systems, for:
• System operation, maintenance, and capital improvement-related activities.”

COMPLIANCE
a. When the City experiences a spill, it is standard procedure to secure the affected area and keep the public away. This is generally done using barricades, cones and caution tape. Should the City experience a spill that may require closure of public areas or enter a source drinking of water, signs will be immediately placed indicating the issue and providing contact information. Staff will remain on site to provide an additional safety factor until appropriate authorities respond and direct otherwise. In all cases, the City will follow the advice of higher authorities, such as the local environmental health department and other regulatory authorities. b. There are several opportunities for stakeholders and the public to participate and provide input into the development and update of the City’s SSMP. During its initial development stage, as with each SSMP Audit and update of the SSMP, the SSMP and related documents are presented to the City Council for review and acceptance. With the adoption of the new WDR, SSMP Audits are now performed every three years and re-certification and acceptance of updated SSMPs are required every six years. Prior to each City Council Meeting, these documents are included in Agenda packet which are readily available for review on the City’s website.

The City’s website includes the Wastewater Planning page which has links to the City’s 2020 Wastewater Master Plan, this SSMP, and the 2007 Yuba-Sutter Regional Recycled Water Maste Plan.

The City’s Public Works page provides the public with several ways to contact the City. c. This section does not apply.

2 Overview
The City operates the City of Yuba City collection system and its satellite, the Stonegate Village collection system.

System Name Waste
Discharger
Identification
Number
Audit Period Audit
Due Date
Yuba City CS 5SSO11100 8/3/2021 – 8/2/2024 2/2/2025
Stonegate Village CS 5SSO11060 8/3/2021 – 8/2/2024 2/2/2025 The Yuba City sewer system includes 173 miles of gravity pipeline, ranging from 4 inches to 42 inches in diameter. Stonegate Village is served by a septic tank effluent pumping (STEP) system, with 1.85 miles of pressurized sewer lines.

Audit Purpose and Background
The purpose of the SSMP audit is to evaluate the effectiveness of the City’s efforts to manage, design, operate, and maintain the sanitary sewer system. The audit includes an assessment of the SSMP’s compliance with mandated requirements, an evaluation of the effectiveness of the City’s current program, identification of elements needing to be updated, and recommended improvements.

This report summarizes the results of the 2025 audit of the Sewer System Management Plan by the City of Yuba City SSMP Audit Committee. The audit covers the period August 3, 2021 through August 2, 2024, and was completed with assistance from the Maintenance, Utilities, and Engineering Divisions of the City’s Public Works and Development Services Divisions.

The City has been actively upgrading the sanitary sewer system since 2012 through capital improvement projects and its operations and maintenance activities. Over time, the City has succeeded in significantly reducing the number and volume of wastewater spills.

This reflects a combination of operational practices, equipment acquisition, and improvements to the collection system.

3 In the years leading up to this audit period, the City conducted the following activities:
• DowntownAreaCollection System Rehab/Replacement
Over $10 million was invested to replace and rehabilitate sewer mains in the Yuba City downtown core district from 2012 through 2014. Many segments of the City’s collection system dated back to the early 1900s.

Most of the sewer pipelines in this project area were constructed in 1926.
• SmartCoverMonitoring
The City started installing SmartCover System sensors in manholes beginning in 2014 to detect potential lift station problems, and provide alarms if lift stations were not keeping up with the necessary pumping rates.
• Generators
Permanent standby generators were installed at three lift station sites.

Generator hookups were installed at all 17 lift station sites. • Lift Station Odor Control
Ozone odor control systems were installed at Lift Station #2 and Lift Station #10.

During the audit period, the following project was completed:
• Sewer Main Lining Project
In 2021, the City relined approximately 2,590 linear feet of 42-inch Techite pipe trunk line from Lincoln Road and the Garden Highway to the WWTF. The 2020 Wastewater Master Plan recommended the removal or rehabilitation of 9,420 feet of Techite reinforced plastic mortar pipe in the City’s wastewater collection system due to its high failure rate.

4 Operations and Maintenance Projects and Initiatives
As outlined in the first column of the following table, the City is focusing on the following elements of its collections system operations and maintenance program. The second column provides an assessment of the activities that occurred during the audit period.

May 2023 SSMP Update Guidance August 2021 – August 2024 Performance Sewer jetting work with a goal to clean the
collection system on a 3-year cycle.

A review of sewer jetting records over the
audit period indicates the Collections crew is
close to meeting this target.

Sewer CCTV work with a goal to inspect the
collection system on a 5-year cycle.

A review of TV inspection records indicates
the Collections crew is close to meeting this
target.

Contracted chemical root control
using an herbicide to kill roots that
have grown into the sewer system.

Roots are particularly problematic
where sewer mains are located in
backyard easements.

The City contracts for a company
to treat about 3 miles a year. Due
to a sanitary sewer spill (SSS) in
May 2023, an additional line
segment was added to this
program to prevent future spills at
this location.

High-frequency cleaning of pre-selected
pipeline segments where history has shown
that grease or debris will cause sewer
backups or SSSs unless cleaned on a high
frequency
The City replaced sewer mains on
two segments of historically
problematic pipelines. These were
removed from the high-frequency
cleaning list.

The City replaced sewer mains on two
segments of historically problematic
pipelines. These were removed from the
high-frequency cleaning list.

The City replaced sewer mains on two
segments of historically problematic
pipelines. These were removed from the

backups and spills.

Increasing inspection frequency for food
service establishments
Conducting preventative maintenance at
each sewer lift station on an annual basis.

Annual preventative lift station maintenance
was conducted consistent with the
scheduled frequency.

Replacing critical septic system
components at 112 Stonegate Village
services every three years.

The replacement frequency was changed to
every two years to improve reliability of the

CITY OF YUBA CITY

STAFF REPORT
Date: July 1, 2025
To: Honorable Mayor & Members of the City Council;
From: Public Works
Presentation By: Joshua Wolffe, Senior Engineer
Summary
Subject: Yuba City Landscape District No. 1 - Resolution of Intent Recommendation: A. Adopt the following Resolutions to continue the Maintenance Districts pursuant to the Landscaping and Lighting Act of 1972:
• Resolution Approving Engineer's Reports Yuba City Landscape Maintenance District No.1
• Resolution of Intention to Levy and Collect Assessments, Yuba City Landscape Maintenance District No.1
B. Set a Public Hearing for July 15, 2025 at 6:00PM to establish assessments for Fiscal Year (FY) 2025-26
Fiscal Impact: Receipt of assessments and expenditure of funds for lighting and landscape maintenance districts throughout the City.

Purpose:

To continue to provide lighting and landscape maintenance throughout the City pursuant to the provisions of the Landscaping and Lighting Act of 1972 and Article XIIID of the California Constitution.

Council Strategic Goal:

Levying Yuba City Landscape Maintenance District No. 1 (LLMD 1) addresses the City Council's Strategic Goal of maintaining infrastructure, as levying LLMD No. 1 will ensure that landscaping, and other items included in the District are maintained and in operation.

Background:

The City annually levies and collects special assessments in order to maintain and service landscaping and lighting improvements that provide special benefit to the parcels identified in LLMD 1. The assessments were approved by the property owners of record through a protest-ballot proceeding at the time the Districts were formed.

LLMD 1 includes the Stabler Lane area (Zone of Benefit A) and Garden Highway Area (Zones of Benefit B, B_1, and B_2). Zones of Benefit A and B do not have provisions for a cost of living

adjustment (COLA) and have historically been charged the maximum levy allowed in order to cover their annual expenses. Zones B_1 and B_2 are recently formed zones of benefit and do have provisions for a COLA which is based on the Consumer Price Index from January to January.

Analysis:

The Engineer's Annual Report has been prepared and is on file in the City Clerk's office. It describes each District, the improvements therein, the method of assessment and the proposed assessment for each parcel. The Resolution of Intention to levy and collect assessment is required by state law for existing districts. The proposed action in this report sets a public hearing for the Council meeting to be held on July 15, 2025 to establish assessments for the coming year.

District No. 1, Zones of Benefit B_1 and B_2 will see increases in their annual levies. The levies were raised in response to inflation. District No. 1 Zones of Benefit A and B will continue to be levied at the maximum amount, and will not be increased further due to their lack of COLAs.

Fiscal Impact:

The proposed assessments for FY 2025-26 are shown in Attachment 3.

The projected revenue, expenditures, and cash balance, which include capital reserve for the Districts, are as follows:

District Revenue Expenditures Projected Reserve Fund Balance as of 07/01/2026*
1A $22,007.36 $22,022.90 ($4,138.83)
1B** $65,802.70 $66,385.20 ($5,205.80)
*The Projected Reserve Fund Balance is the total of the Capital Replacement Reserve plus the Operating Reserve.
**Dollar amounts for Zones of Benefit B, B_1 and B_2 are included within the "1B" row of the table.

District 1 was formed in 1990 with no COLA, therefore the District's funding is annually based on 1990 dollars. This means that in District 1, Zone of Benefit A, each parcel pays $56.72 annually; and in Zone of Benefit B, each parcel pays $29.50 annually. Staff has reduced maintenance in District 1 to minimal levels in attempts to keep the District's balance positive. With increases in maintenance, water, and electrical costs, it has become increasingly difficult to provide minimally acceptable maintenance. If the Zones of Benefits' rates were inflated to 2025 dollars, the annual amounts per parcel would be $141.33 and $73.50, respectively. The current average annual per-parcel rate among all other residential LLMDs in the City is approximately $200.

Moving forward, staff will need to continue with reducing services in these Zones of Benefit due to lack of funding. In order to correct the funding issues, and re-establish great aesthetics through higher levels of maintenance, staff may conduct a Proposition 218 hearing to modify the District for inclusion of COLAs.

Alternatives:

1. Council may direct City staff to follow legal procedures in order to modify District No. 1, increasing assessment amounts to a level appropriate for maintenance, and including a Cost of Living Adjustment.

2. Council may cancel the district and find alternative funding sources to maintain the landscaping and related items in this area.

Recommendation:

A. Adopt the following Resolutions to continue the Maintenance Districts pursuant to the Landscaping and Lighting Act of 1972:
• Resolution Approving Engineer's Reports Yuba City Landscape Maintenance District No.1 • Resolution of Intention to Levy and Collect Assessments, Yuba City Landscape Maintenance District No.1
B. Set a Public Hearing for July 15, 2025 at 6:00PM to establish assessments for Fiscal Year (FY) 2025-26

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 2 of 16 I. OVERVIEW
A. INTRODUCTION
The City of Yuba City (“City”) annually levies and collects special assessments to maintain and service landscape improvements that provide special benefit to the Yuba City Lighting and Landscape Maintenance District (“District”). The District is annually levied pursuant to the Landscape and Lighting Act of 1972, Part 2 of Division 15 of the California Streets and Highways Code (“1972 Act”). The District assessments were approved by the property owners of record through a protest ballot proceeding at the time the District was formed in compliance with the substantive and procedural requirements of the California Constitution Article XIIID (“Article XIIID”).

This Engineer’s Annual Levy Report (“Report”) has been prepared in accordance with the provisions of Chapter 3, Section 22622 of the 1972 Act. This Report describes the District, the improvements therein, any annexations or other modifications to the District including any substantial changes to the improvements, the method of apportionment, the boundaries of the District, and financial information including the district budgets and proposed annual assessments for Fiscal Year 2025/2026. The proposed assessments are based on the historic and estimated costs to maintain the improvements that provide a direct and special benefit to properties within the District. The costs of improvements and the annual levy including all expenditures, deficits, surpluses, revenues, and reserves are assessed to each parcel within the District proportionate to the parcel’s special benefits.

For the purposes of this Report, the word “parcel” refers to an individual property assigned its own Assessor Parcel Number (“APN”) by the County of Sutter (“County”) Assessor’s Office. The County Auditor/Controller uses APNs and specific fund numbers to identify properties assessed for special district benefit assessments on the tax roll.

Pursuant to Chapter 3, beginning with Section 22620 of the 1972 Act, the City Council shall conduct a noticed annual public hearing to consider all public comments and written protests regarding the District. Following the annual public hearing and review of the Report, the City Council may order amendments to the Report or confirm the Report as submitted. Following final approval of the Report and confirmation of the assessments contained therein, the City Council will by resolution: order the improvements to be made and confirm the levy and collection of assessments pursuant to Chapter 4, Article 1, beginning with Section 22640 of the 1972 Act. The assessment rates and method of apportionment described in this Report define the assessments to be applied to each parcel within the District for Fiscal Year 2025/2026.

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 3 of 16 The assessments as approved will be submitted to the County Auditor/Controller to be included on the property tax roll for each parcel within the District. If any parcel submitted for collection is identified by the County Auditor/Controller to be an invalid APN for the current fiscal year, a corrected parcel number and/or new parcel numbers will be identified and resubmitted to the County. The assessment amount to be levied and collected for the resubmitted parcel or parcels shall be based on the method of apportionment and assessment rate contained in this Report as approved by the City Council.

B. COMPLIANCE WITH CURRENT LEGISLATION
On November 6, 1996, California voters approved Proposition 218 by a margin of

56.5% to 43.5%. All assessments described in this Report and approved by the City Council are prepared in accordance with the 1972 Act and are in compliance with the provisions of the California Constitution Article XIIID (Proposition 218).

Pursuant to the California Constitution Article XIIID Section 5, certain existing assessments are exempt from the substantive and procedural requirements of Article XIIID Section 4 and property owner balloting for the assessments is not required until such time that the assessments are increased. Specifically, the City determined that all improvements and the annual assessments originally established for the District were part of the conditions of property development and approved by the original property owner (developer). As such, pursuant to Article XIIID Section 5(b), all the property owners approved the existing District assessments at the time the assessments were created (originally imposed pursuant to a 100% landowner petition). Therefore, the pre-existing assessment amounts are exempt from the procedural requirements Article XIIID Section 4.

The District has been formed pursuant to the Landscaping and Lighting Act of 1972, Part 2 of Division 15 of the California Streets and Highways Code.

Pursuant to the 1972 Act, an annual Public Hearing is conducted by the City Council to accept property owner and public comments, to review the Engineer’s Annual Levy Report prior to approving the annual assessments to be levied on the County tax rolls. The assessments described in this Report have been prepared in accordance with the Act.

The City affirms that the assessments contained in this report for Zones A and B, were imposed in accordance with a consent and waiver by 100% of the property owners as part of the original development approval for the properties within the District. Therefore, the City has determined that pursuant to Article XIIID Section 5(b) the maximum assessment previously approved and levied for these Zones prior to the passage of Proposition 218 are considered exempt, provided the assessments are not increased above these previously approved maximum assessment rates.

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 4 of 16 The proposed annual levy of assessments for fiscal year commencing July 1, 2025 and ending June 30, 2026 (Fiscal Year 2025/2026) as described in this Report have been prepared and made pursuant to the provisions of the 1972 Act and are consistent with the assessments previously approved and adopted by the City Council. The assessments described herein for Fiscal Year 2025/2026 do not exceed the maximum assessment rates authorized and are therefore in compliance with the provisions of the California Constitution Article XIIID.

II. PLANS AND SPECIFICATIONS

The Zone of Benefit B-2 (“Zone B-2”) benefits two commercial parcels located at 1500 and 1510 Garden Highway.

B. DESCRIPTION OF THE IMPROVEMENTS
The District improvements provide for the ongoing maintenance and servicing of landscaping improvement areas adjacent to Zone A, Zone B, Zone B-1 and Zone B-2 as shown on the Assessment Diagrams on file with the City Clerk.

Maintenance improvements may include but are not limited to: turf, ground cover, shrubs, trees, plants, irrigation and drainage systems, ornamental lighting structures, masonry walls or other fencing, entryway monuments, and associated appurtenant facilities located within the streetscape (perimeter landscaping)

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 5 of 16 surrounding the developments. Servicing improvements may include, but are not limited to: electricity, water for irrigation of any landscaping, and the operation of fountains.

The annual cost and expenses of providing the landscape maintenance and servicing in Zone A, Zone B, Zone B-1 and Zone B-2 are estimated separately and are apportioned equally to all lots, developed or undeveloped, within each Zone.

III. METHOD OF APPORTIONMENT
A. GENERAL
The 1972 Act permits the establishment of assessment districts by agencies for the purpose of providing certain public improvements which include the construction, maintenance and servicing of public lights, landscaping and appurtenant facilities. The 1972 Act further requires that the cost of these improvements be levied according to benefit rather than assessed value:
“The net amount to be assessed upon lands within an assessment district may be apportioned by any formula or method which fairly distributes the net amount among all assessable lots or parcels in proportion to the estimated benefits to be received by each such lot or parcel from the improvements.”
The formula used for calculating assessments in the District therefore reflects the composition of the parcels, and the improvements and services provided, to fairly apportion the costs based on estimated benefit to each parcel.

In addition, pursuant to the Article XIIID Section 4, a parcel’s assessment may not exceed the reasonable cost of the proportional special benefit conferred on that parcel and provides that only special benefits are assessable and the District must separate the general benefits from the special benefits.

B. BENEFIT ANALYSIS
Each of the improvements and the associated costs has been carefully reviewed and the corresponding assessments have been proportionately spread to each parcel based on special benefits received from the improvements. The installation of the improvements was part of the conditions of property development. The property owners approved the corresponding assessments for the ongoing maintenance and servicing of the improvements through a property owner protest ballot.

Special Benefits — the method of apportionment (assessment methodology) is based on the premise that each of the assessed parcels within the District

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 6 of 16 receives benefit from the improvements maintained and financed by annual assessments. Specifically, the assessments are for the maintenance of landscaped improvements installed as part of the original development. The desirability of properties within the District is enhanced by the presence of wellmaintained landscaping in close proximity to those properties.

The special benefits associated with the local landscaping improvements are specifically:
 Enhanced desirability of properties through association with the improvements.
 Improved aesthetic appeal of properties within the Zones providing a positive representation of the area.
 Enhanced adaptation of the urban environment within the natural environment from adequate green space and landscaping.
 Environmental enhancement through improved erosion resistance, and dust and debris control.
 Increased sense of pride in ownership of property within the District resulting from well-maintained improvements associated with the properties.
 Reduced criminal activity and property-related crimes (especially vandalism) against properties in the District through well-maintained surroundings and amenities including abatement of graffiti.  Enhanced environmental quality of the parcels within the Zones by moderating temperatures, providing oxygenation and attenuating noise.

General Benefits - the improvements to be provided and maintained by the District are a direct result of property development within the District and would otherwise not be required or necessary. Developers typically install local improvements to enhance the marketability and value of properties within the development and/or as conditions of development. In either case, the improvements are clearly installed for the benefit of the properties being developed and not for the benefit of surrounding properties outside the District boundaries. Although local development improvements (by virtue of their location) may be visible to surrounding properties, any benefit to surrounding properties is incidental and cannot be considered a direct and special benefit.

Furthermore, most developments within the City typically have various landscaping and lighting improvements specifically associated with their development and these improvements are funded by properties within those developments.

At the time of formation of the Assessment District, the majority of the benefit was special, and there was a small general benefit. The engineer of record between Fiscal Year 2012/2013 and Fiscal Year 2015/2016, further quantified this small general benefit.

2025/2026 Lighting and Landscape Maintenance District No. 1 Page 7 of 16 The specific language from the most recent Engineer’s Report used to describe General Benefit is as follows:

The maintenance and servicing of these improvements is also partially refunded, directly and indirectly from other sources including Yuba City, Sutter County and the State of California. This funding comes in the form of grants, development fees, special programs, and general funds, as well as direct maintenance and servicing of facilities (e.g. curbs, gutters, streets, drainage systems, etc.) This funding from other sources more than compensates for general benefits, if any, received by the properties within the Assessment District.

The General Benefits from this assessment may be quantified as illustrated in the following table.

Benefit Factor Relative
Weight
General Benefit
Contribution
Relative
General
Benefit
Creation of parcels 90 0% 0
Extention of recreation area 2 10% 0.2
Proximity to improved parks and recreation facilities 2 10% 0.2 Access to improved parks, open space and rec areas 2 10% 0.2 Improved views 2 10% 0.2
Improved nighttime visibility and safety from streetlights 2 20% 0.4 Totals 100 1.2
Total Calculated General Benefit 1.2%
As a result, Yuba City will contribute at least 1.2% of the total budget from sources other than the assessment. This contribution offsets any general benefits from the Assessment Services.

This general benefit contribution is the sum of the following components:

Yuba City owns, maintains, rehabilitates and replaces curb and gutter along the border of the Assessment District improvements. This curb and gutter serves to support, contain, retain, manage irrigation flow and growth, and provide a boundary for the improvements. The contribution from the City towards general benefit from the maintenance, rehabilitation and replacement of the curb and gutter is conservatively estimated to be 1%.

Yuba City owns and maintains a storm drainage system along the border of the Assessment District improvements. This system serves to prevent flooding and associated damage to the improvements, and manage urban runoff including local pollutants loading from the improvements. The
