STAFF REPORT
DATE: July 29, 2025
TO: Honorable Mayor and Members of the City Council
VIA: Melvin E. Gaines, City Manager
BY: Shiri Klima, Assistant City Manager
Ana Maria Torres-Mondragon, Human Resources Manager
SUBJECT: Personnel Staffing Change, POA Side Letter Agreement, and Classification Specification Updates
Recommendation

1. Approving an amendment to the City’s Classification Plan adding 1.0 FTE Housing Specialist I/II (1 year LTD);

2. Approving classification updates to the following:
a. Community Services Officer

3. Approving and establishing the related compensation schedules;

Alignment with City Council Strategic Plan
This recommendation is primarily aligned with:

Priority: Governance, Organizational Strength, and Fiscal Sustainability 10 CONSENT ITEM 3.1
Background
Because of the evolving needs of the City, changes related to staffing, community expectations, and management’s intent to continue pursuing Council’s strategic goal of “Governance, Organizational Strength, and Fiscal Sustainability,” staff is proposing several changes related to the City’s departmental organization and staffing. These proposed changes will support critical ongoing Community Development and Police Department initiatives, ultimately strengthening the overall managerial control and responsibility for the City’s current service levels. Two side letters are being presented to illustrate the City’s ongoing efforts to work collaboratively with labor on important matters.

As codified in the City’s Personnel Policies and Procedures approved by the City Council on August 28, 1985 (Resolution #00210), Rule 3.4.05 states: “A job specification shall be a written statement providing the title and definition of a class, examples of the duties to be performed and the minimum qualifications.” As a member of the California Public Employees’ Retirement System (CalPERS), the City is also subject to applicable provisions of the Public Employee Retirement Law (PERL) referenced in the California Government Code and the California Code of Regulations.

Section 3.4.06 of the City of East Palo Alto Personnel Policies and Procedures manual establishes the procedures for department heads or the Personnel Officer (which is the City Manager) to create a new classification. Requests for the creation of a new class can be made by a department head to the Personnel Officer, or by the Personnel Officer. After review, the Personnel Officer submits the new job specification, class title and salary range to the City Council to be considered for addition to the Classification Plan. The new class is officially established upon adoption by the City Council.

Analysis
Staff is proposing the following staffing changes:

Police Department
Operations Division
Staff is proposing a classification update for the Community Services Officer classification as a strategic effort to broaden our applicant pool. The minor edit is to update the minimum qualifications from require experienced law enforcement to a desired qualification going forward.

Community and Economic Development Department
The Community and Economic Development Department oversees Building, Housing/ Rent Stabilization, and Planning services for the City.
11 CONSENT ITEM 3.1
Housing Division
During the FY25-26 budget process, staff requested and were granted the addition of 1.0 FTE Housing Specialist I/II (1 Year LTD) classification to assist with providing critical support to both divisions and aligns directly with Council-adopted priorities in Housing and Rent Stabilization.

This classification requires a new job description, as described below.

The incumbent is intended to advance and sustain several initiatives for Housing and Rent Stabilization, including four new items added to the Council priorities list including: an Inclusionary Housing update, a First-Time Home Buyer Program, a Home Repair Program, and Foreclosure Prevention Initiatives. The incumbent will also support existing projects and programs including anti-displacement services through Measure JJ and housing preservation as identified in the Housing Element.

The incumbent is also intended to advance and sustain several initiatives for Rent Stabilization Program such as assist in the implementation and administration of the City’s new Rent Registry, monitor compliance for both legacy and new units under Just Cause, supporting increased demand for Just Cause workshops and Ellis Act compliance, and collaborating with the two current RSP staff to process petitions
Functions under these two divisions will increase efficiency and services.

Side Letter Updates:

Police Officer’s Association (POA)
The City is amending the Police MOU Article 17.1: Probationary Period to allow probationary periods to be extended when an employee goes on extended leave (30 consecutive days or more) during their probation. This change ensures that the employee receives his or her full probationary period in active service, giving him or her a fair opportunity to demonstrate performance.

This update aligns with the City’s operational needs by maintaining consistent evaluation standards, while also supporting employees fairly and equitably. Ultimately, this amendment benefits both the City and the employee, ensuring everyone has the time and information needed for long-term success.

All meet and confer obligations required for this staff report have been met.

These proposed changes will improve the efficiency of existing services related to the Police Department and Community and Economic Development Department.

Fiscal Impact
There is no fiscal impact for this item. Approval of the positions added to the FY2025-26 budget have already been complete as a part of the budget process. Additionally, the pay schedule for 12 CONSENT ITEM 3.1
these positions was already approved on June 17, 2025. This item involves approving the job descriptions only; if approved, City staff will proceed with releasing the recruitments for these positions and utilize the funds from these budgeted positions.

Public Notice
The public was provided notice by making the agenda and report available on the City’s website and on a bulletin board located at City Hall: 2415 University Avenue, East Palo Alto.

Environmental
The proposed action does not constitute a “project” with the meaning of the California Environmental Quality Act (“CEQA”) pursuant to CEQA Guidelines sections 15378(b)(4) and (5) in that it is a governmental fiscal, organizational or administrative activity that will not result in direct or indirect changes in the environment.

Government Code § 84308
Applicability of Levine Act: No, as there are no entitlements related to the proposed action.

Analysis of Levine Act Compliance: Not applicable.

Humza Javed, Public Works Director
SUBJECT: Grant Application for the 2025 Cycle 3 Transportation Demand Management (TDM) Program
Recommendation
Adopt a resolution:

2. Finding that the proposed action does not constitute a “project” with the meaning of the California Environmental Quality Act (“CEQA”) pursuant to CEQA Guidelines sections 15378(b)(4) and (5) in that it is a governmental fiscal, organizational or administrative activity that will not result in direct or indirect changes in the environment.

Alignment with City Council Strategic Plan

Background
34 CONSENT ITEM 3.3
The San Mateo County Transportation Authority (TA) issued a Call for Projects for the Measure A Alternative Congestion Relief & Measure W Transportation Demand Management (ACR/TDM) Program on June 5, 2025. The Cycle 3 TDM Program will release approximately $7.97 million in available Measure A and W funds. The program aims to encourage the use of sustainable transportation options and enhance mobility across San Mateo County.

Staff proposes to apply for a project that will refine and implement the City’s Transportation Demand Management (TDM) Ordinance, which was adopted June 1, 2021. The ordinance can be found here:
https://www.cityofepa.org/publicworks/page/transportation-demand-management-tdm Analysis
On May 17, 2022, the City Council authorized a contract with Cities21 for TDM program administration. Cities21 is a professional working for better transit, greater urban livability, and reduced pollution, including elements such as transit villages, real estate in-fill, workforce housing, automated transit, and wireless connection-making software. Over the last few years Cities21 has assisted the City in implementing our TDM ordinance. The contract with Cities21 expired in June 2025, and is being extended to allow for program monitoring.

City staff have identified next steps associated with the TDM Program implementation and additional support for the next phase is needed. Staff is requesting $150,000 from the TA for the refinement and implementation of the City’s TDM Ordinance as well as to develop TDM projects/actions for the City to implement.

The scope will include, but is not limited to, revising/amending the ordinance and program guidelines, the review of TDM plans for compliance, coordinating with San Mateo County on TDM requirements, and reviewing annual TDM plans.

Fiscal Impact
There is no fiscal impact associated with submitting the application; however, the grant includes a minimum funding match of $7,895 which can be covered by Measure M funds.

Public Notice
The public was provided notice by making the agenda and report available on the City’s website and on a bulletin board located at City Hall: 2415 University Avenue, East Palo Alto.

SUBJECT: Approval of Settlement Agreement
Recommendation
By motion, approve and authorize the City Attorney to sign a settlement agreement in the matter of Sandra Floyd v. City of East Palo Alto (24-CIV-00140).

Alignment with City Council Strategic Plan
This recommendation is primarily aligned with:

Priority: Governance, Organizational Strength, and Fiscal Sustainability Background
On February 26, 2024, the City Manager’s Office was served with a lawsuit by and through Ms.

Moira C. McQuaid, who represents Ms. Sandra Floyd.

The city employed Ms. Floyd as its Human Resources Manager from March 1, 2022, until November 28, 2022.

The city retained legal counsel Serena Warner of Angelo, Kilday & Killduff, LLP. In April 2025, the case went to mediation before mediator Tamara Lange (JAMS). Mediation did not lead to a settlement proposal at that time.

Analysis
As reported to the City Council on May 6, 2025, the parties participated in mediation but were unable to settle the matter. The City Attorney’s Office has engaged in additional settlement discussions with Ms. Floyd’s legal counsel to explore a potential settlement. Recently, the 40 COUNCIL REPORTS 3.4
Council met in closed session to consider settlement options. At that time, direction was given to staff concerning how to proceed with settlement.

The City Attorney returns to open session to approve the agreement.

Fiscal Impact
The proposed settlement would involve payment of $80,000.

Public Notice
The public was provided notice by making the agenda and report available on the City’s website and on a bulletin board located at City Hall: 2415 University Avenue, East Palo Alto.

EAST PALO ALTO

CITY COUNCIL

STAFF REPORT
DATE: July 29, 2025
TO: Honorable Mayor and Members of the City Council
VIA: Melvin E. Gaines, City Manager
BY: Jeff Liu, Chief of Police
SUBJECT: Purchase of Two Police Patrol Vehicles
Recommendation
Adopt a resolution:

1. Authorizing the City Manager to purchase two 2025 Dodge Durango Police Vehicles from Elk Grove Auto Group for the Police Department in an amount not to exceed $116,954.26; and

2. Approve the purchase under an exception to formal bidding procedures pursuant to East Palo Alto Municipal Code Section 2.84.0740(DL); and

Alignment with City Council Strategic Plan
This recommendation is primarily aligned with:

Priority No. 1: Enhance Public Safety and Emergency Preparedness Background
46 CONSENT ITEM 3.6
On December 6, 2005, the City Council adopted Resolution No. 2532A, which established the City’s Vehicle Fleet and Replacement Guidelines. These Guidelines outline the standards by which the City replaces its vehicles. According to the Guidelines, patrol vehicles shall be replaced at five years or 100,000 miles (December 6, 2005 Staff Report and Resolution No. 2532A). This policy ensures City patrol vehicles remain operable with reasonable maintenance. This policy also ensures police vehicles are safe and effective, especially considering the high-risk nature of police driving.

The City considered purchasing two new 2025 Dodge Durango Police Vehicles for $116,954.26 to replace two vehicles that exceed the vehicle age and mileage limits set by City of East Palo Alto City Council Resolution Number 2532A.

Analysis
The purchase of these two vehicles will allow the Department to continue safe, effective and efficient management of its police vehicle fleet.

If Council approves the purchase of these vehicles, the City will replace two vehicles that are over five years old and/or have over 100,000 miles of service. After the Police Department puts the new vehicles into service, the vehicles being replaced will be mechanically assessed to determine whether they can be used as non-emergency City vehicles or for spare parts. If either replaced vehicle has no value, it will be disposed of in a manner approved by the City Manager.

The City proposes to purchase the vehicles for $116,954.26 from Elk Grove Auto Group, a contractor on the State of California Statewide Contracts for Fleet Vehicles list. This list provides fleet vehicles at contracted pricing to the State of California and local governmental agencies. Elk Grove Auto’s contract #1-22-23-23E with the State has a term through April 30, 2026. Local governmental agencies have the same rights and privileges as the State under the terms of this contract, including pricing.

Staff recommends that the City Council approve this exception to the formal bidding requirements for this purchase in favor of using the State’s Statewide Contracts for Fleet Vehicles pursuant to Section 2.84.040(L) for piggybacking. The State of California’s contract with Elk Grove Auto’s (Contract #1-22-23-23E) conforms to the State bid specifications, which was competitively bid. Additionally, pricing under this bid was updated in June 2023.

Accordingly, it is not likely that conducting a new bid process for the purchase of these two vehicles will result in a lower price to the City. Thus, the City Manager therefore recommends proceeding under this exception to formal bid procedure under East Palo Alto Municipal Code Section 2.84.040(L).
1 1
“When other special circumstances require, and the City Manager recommends disregarding bid procedures, and City Council approval is obtained to disregard bid procedures and which expressly authorizes negotiations with one or more firms, persons, corporations, partnerships and/or associates for entities.” EPAMC 2.84.070(D).
47 CONSENT ITEM 3.6
Fiscal Impact
The fiscal impact is $116,954.26 from the General Fund. For the Fiscal Year 2025-26 budget, the Police Department budgeted $120,500 for vehicle purchases, which is adequate for these purchases.

Public Notice
The public was provided notice of this agenda item by posting the City Council agenda on the City’s official bulletin outside City Hall and making the agenda and report available at the City’s website and the San Mateo County Library at 2415 University Avenue.

Government Code § 84308
Applicability of Levine Act: Yes.

Analysis of Levine Act Compliance: The signatory for the agreements is Andrew Villareal of Elk Grove Auto. Staff is unaware of any other parties or participants relevant to the Council’s consideration of this item.

EAST PALO ALTO

SANITARY DISTRICT

STAFF REPORT
DATE: July 29, 2025
TO: Honorable Members of the City of East Palo Alto City Council, Governing Board to the East Palo Sanitary District, a Subsidiary of the City of East Palo Alto VIA: Melvin Gaines, General Manager
BY: Humza Javed, District Engineer
SUBJECT: 2025 Sanitary Sewer Management Plan Update
Recommendation
Adopting a resolution:

1. Adopting the 2025 Sanitary Sewer System Management Plan; and

2. Finding that the proposed action is exempt from the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines section 15308 (Protection of the Environment).

Alignment with City Council Strategic Plan
This recommendation is primarily aligned with:

Public Infrastructure and Utilities
Background
On November 15, 2023, the San Mateo Local Agency Formation Commission (LAFCo) unanimously approved the City of East Palo Alto’s application to designate the East Palo Alto Sanitary District (EPASD or “District”) as a subsidiary district of the City. The reorganization took effect on October 1, 2024, when the City Council assumed governance of EPASD.

EPASD remains a legally separate entity from the City, and its assets are kept distinct On December 6, 2022, the State Water Resources Control Board (SWRCB) adopted Statewide Waste Discharge Requirements General Order for Sanitary Sewer Systems with greater than one mile of collection lines, and the new order went into effect on June 5, 2023, and is herein referred to as the “General Order”. The purpose of this General Order is to 69 EPASD BOARD CONSENT ITEM 10.1
ensure that public agencies that own or operate sanitary sewer systems develop and implement sewer system management plans and report all sanitary sewer spills to the SWRCB’s online California Integrated Water Quality System (CIWQS) Sanitary Sewer System Database using the City Waste Discharge Identification Number 2SSO10129. The goal of the General Order is to minimize sewer spills, protect the Waters of the State and assure proper management and operation of the sanitary sewers.

The updated General Order also requires each public agency to update the Sanitary Sewer Management Plan (SSMP) every six years and include any significant program changes. The updated SSMP must be approved by the governing board upon completion of the update, certified by the City’s legally responsible official and uploaded to the CIWQS system no later than August 2, 2025. This resolution is for the District Board to approve the updated SSMP, as required under the General Order, by August 2, 2025. Thereafter, under the new General Order, re-certification will be required every 6 years.

Analysis
The SSMP is a living planning document that must address, at a minimum, the required SSMP elements of the General Order. To be effective, the SSMP must include procedures for the management, operation, and maintenance of the sanitary sewer system. The procedure must incorporate the prioritization of system repairs and maintenance to proactively prevent spills and address the implementation of current standard industry practices through available equipment, technologies, and strategies. Effective management of the District’s Wastewater Collection system includes:
- Provide uninterrupted sanitary sewer service.
- Minimize the risk of spills by reducing the impact and probability of spills and adapting the program from results of operations and spill events. - Mitigate spills to minimize water quality and environmental impacts to Waters of the State.
- Ensure adequate sewer system capacity to address the City’s current and future flows addressing climate change and inflow and infiltration impacts, system resilience and growth.
- Sustain aging sewer infrastructure by implementing an asset management program to extend asset lifecycle.
- Ensure adequate funding support and resources to sustain long-term asset management.
- Assure proper training and field exercises for well-prepared staff at all levels of the program that assures full compliance with the General Order.

The SSMP is organized into 11 Elements identified in the General Order. Each section of the SSMP includes information demonstrating the District’s efforts to comply with each of the mandatory and applicable elements required within the General Order. The organization of this SSMP is consistent with the SWRCB guidelines and includes the following 11 mandatory General Order elements:
70 EPASD BOARD CONSENT ITEM 10.1
- Goal and Introduction
- Organization
- Legal Authority
- Operation and Maintenance Program
- Design and Performance Provisions
- Spill Emergency Response Plan
- Sewer Pipe Blockage Control Program
- System Evaluation, Capacity Assurance, and Capital Improvements - Monitoring, Measurement and Program Modifications
- Internal Audits
- Communication Program
The General Order requires each public agency to update the SSMP every six years and include any significant program changes. The updated SSMP must be approved by the governing board upon completion of the update. Through the District’s SSMP audit process, the District can track and evaluate the effectiveness of the SSMP, identify deficiencies in the management, operation and maintenance of the District’s sanitary sewer collection system, and implement changes to the SSMP to address these deficiencies. The SSMP has been included as Attachment No. 2 to the staff report.

District staff has signed off on the SSMP, and an adopted Resolution by the Board will satisfy compliance with the General Order. District staff will subsequently complete the certification process and upload the document to the SWRCB’s electronic database.

Fiscal Impact
There is no direct fiscal impact with adoption of the SSMP.

Public Notice
The public was provided notice of this agenda item by posting the Advisory Committee agenda on the City’s official bulletin board outside City Hall and making the agenda and report available at the City’s website and at the San Mateo Co. Library located at 2415 University Avenue, East Palo Alto.

Environmental

A?n: Humza Javed
Public Works Director Legally Responsible Official (LRO) 1960 Tate Street
East Palo Alto, CA 94303
Dear Mr Javed
We are pleased to present the new 2025 Sewer System Management Plan (SSMP) Update developed in partnership with District management. The 2025 Update meets and exceeds compliance with the Reissued WDR (State Water Board, Water Quality Order No. 2022-0103-DWQ, A?achment D-10 and Specifica6ons

5.4). The 2025 SSMP has been completely revised to harmonize with industry standard guidelines and incorporates the latest SSMP Audit findings.

The 2025 SSMP is a declara6on of what the District is doing to demonstrate full compliance with the Reissued WDR. A?achment A of the Reissued WDR (page A-4), states “A sewer system management plan is a living document an Enrollee develops and implements to effec6vely manage its sanitary sewer system(s) in accordance with this General Order.” This requires the District to periodically review and update the SSMP as necessary un6l its next required 6-year SSMP Update is completed.

To support these ongoing review and update requirements, this document includes a sample change log that may be used as a reference if a system is not already in place. We encourage you to share this example with all relevant team members responsible for implemen6ng or documen6ng SSMP revisions, to help ensure consistency, transparency, and con6nued compliance.

We look forward to assis6ng the District wherever necessary to fully implement the new 2025 SSMP Update.

Sincerely,
James Fischer, P.E.

Introduc6on
This Sewer System Management Plan (SSMP) or “Plan” has been prepared for the East Palo Alto Sanitary District (District) with technical assistance from Fischer Compliance LLC for mee6ng and exceeding compliance with the State Water Resources Control Board’s 2022 General Waste Discharge Requirements, Order WQ 2022-0103-DWQ for Sanitary Sewer Systems (referred to throughout this document as the WDR). The District provided all details, informa6on and ins6tu6onal insights for prepara6on of the SSMP. The document has been developed to meet the size, scale, and complexity, serving as a “living document” used as a tool for managing and opera6ng the District's sanitary sewer collec6on system. Addi6onally, the latest 2024 Sewer System Management Plan Guidance Manual published by the Bay Area Clean Water Agency (BACWA) was u6lized as a model for development of the document to harmonize formaQng/content and incorporate recommended suggested guidance wherever possible.

The District’s commitment to mee6ng or exceeding regulatory requirements, along with their proac6ve approach to opera6on and management of the collec6on system, has served them well, as evidenced by system performance rela6ve to other agencies in the region and the state.

Figure 1 provides key Agency spill metrics, including data comparing the District’s spill record with state and regional system data. The District consistently performs be?er than the statewide and regional spill rate indices and net spill volumes for all categories of spills from its sanitary sewer collec6on system.

This SSMP reflects the ongoing day-to-day ac6vi6es of the District for the management, opera6on, maintenance, and funding of the District’s sanitary collec6on system. As such, this SSMP is a living document subject to constant review and revision as condi6ons and needs of the collec6on system change. This SSMP relies on numerous suppor6ng documents, which are also subject to change, and which form the basis for how the District performs opera6on and maintenance of the collec6on system. The most current version of the SSMP, although it may be subject to update at any 6me, will be found at the District’s Administra6ve Office. 81 OVERVIEW

1.1. Regulatory Context

WDR REQUIREMENTS
A?. D-1.1 (pg. D-2)
“The Plan Introducon secon must provide a general descripon of the local sewer system management program and discuss Plan implementaon and updates”.

COMPLIANCE
The District is commi?ed to fully implemen6ng the WDR2 which includes addressing all requirements by integra6ng a wide range of programs specifically designed for ensuring the integrity and efficiency of the District’s sanitary sewer collec6on system. Moreover, the District is dedicated to maintaining its collec6on system by implemen6ng various work programs, with a focus on cri6cal areas, to prevent spills, allowing for a comprehensive approach to maintenance. Work programs include CCTV inspec6ons, pipe cleaning, manhole inspec6ons, root control, source control and pipe repair, just to name a few. Work programs are described in more detail in Sec6on 4.2 “Specifica6ons 5.19- Opera6on and Maintenance” of this SSMP.

The District does not employ field staff. The District contracts with the West Bay Sanitary District (WBSD) for opera6on and maintenance of the collec6on system. WBSD operates the East Palo Alto Sanitary District system in the same manner it operates its own.

By priori6zing proac6ve measures and taking a comprehensive approach, the District is well-equipped with a proven track record of effec6vely opera6ng its sanitary sewer collec6on system with the highest levels of service, complying with the WDR, and reducing/elimina6ng sewage spills.

4.2. Preven6ve Opera6on and Maintenance Ac6vi6es

WDR REQUIREMENTS
A?. D-4.2 (pgs. D-4/D-5)
”A scheduling system and a data collecon system for prevenve operaon and maintenance acvies conducted by staff and contractors. The scheduling system must include:
• Inspec6on and maintenance ac6vi6es;
• Higher-frequency inspec6ons and maintenance of known problem areas, including areas with tree root problems;
• Regular visual and closed-circuit television (CCTV) inspec6ons of manholes and sewer pipes.

The data collecon system must document data from system inspecon and maintenance acvies, including system areas/components prone to root-intrusion potenally resulng in system backup and/or failure.”

COMPLIANCE
The purpose of a work order system is to program and track all required inspec6on and maintenance ac6vi6es within the collec6on system to help proac6vely prevent blockages/opera6onal problems or spills.

The District u6lizes the Lucity Computerized Maintenance Management System (CMMS), which allows the District to make informed decisions regarding its assets and infrastructure by using the collected data from field work orders and documented inspec6ons. Note: The West Bay Sanitary District performs all maintenance and inspec6on ac6vi6es and manages system assets and work orders on behalf of the District.

The WBSD employs a quality assurance procedure that u6lizes a color-coded mapping system to track maintenance ac6vi6es that have been completed and ac6vi6es that were scheduled to be completed, to help ensure all work was completed as scheduled.

The CMMS maintains historical data for all maintenance ac6vi6es and provides a basis for cri6cal analysis and data-driven planning and decision-making today and into the future. This allows for priori6zing and planning rou6ne ac6vi6es such as CCTV inspec6ons, pipe cleaning and pump sta6on maintenance ac6vi6es.

In addi6on, the CMMS is used to plan and schedule higher-frequency inspec6on and maintenance ac6vi6es such as Hot Spot cleaning and root control ac6vi6es. Emergency and other reac6ve ac6vi6es are documented in work orders as well.

The scheduling system allows staff to put certain ac6vi6es on a preven6ve schedule where staff create work orders on a prescribed interval. Work orders for other ac6vi6es are generated by supervisory personnel on an as-needed basis.

EFFECTIVENESS
The District u6lizes the following Key Performance Indicators for measuring effec6veness of this Element:
• Are the District’s maintenance, opera6ons, engineering work orders periodically audited for accuracy and completeness?
• Does the District monitor “open,” “overdue,” or “not yet completed” work orders to ensure comple6on of tasks?

Specifica6ons 5.19 - Opera6ons and Maintenance

WDR REQUIREMENTS
Specifica6on. 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
Below are brief descrip6ons of work programs performed by the West Bay Sanitary District on behalf of District:

Sewer Cleaning
The District’s primary sewer maintenance ac6vity is high pressure hydro-jeQng. The District has established a “Regular” Preventa6ve Maintenance (PM) applicable to every mainline pipe and a “High Frequency” PM cleaning program for pipes deemed to require a more frequent cleaning. These two cleaning programs are discussed below.

The Regular PM Cleaning consists of high-pressure hydro jet cleaning every gravity mainline pipe in the District ranging from 4” through 10” pipe, in 12–16-month intervals. Pipe sizes 12” to 21” are cleaned in 36- month intervals. Pipe sizes 24” to 54” are cleaned in 60-month (5 year) intervals. The District primary cleaning nozzle is the Worthog Nozzle for the ½ Inch Je?ers and the Hydraulic Rootsaw or Warthog for the ¾ inch and 1-inch je?ers; but for more aggressive root growth the Super Nova Chain Flail may be used.

Where the root saws are deployed, a proofing tool is u6lized to ensure a high-quality cleaning has been performed.

High Frequency PM consists of 1-, 3-, and 6-month high pressure hydro jet cleaning schedules for pipes needing more frequent cleaning. Mainline pipes deemed to require more frequent cleaning are cleaned on the High Frequency cleaning schedule. High Frequency schedules are determined by reviewing the history of mainline stoppages and overflows, and/or by CCTV assessment.

Post Spill Assessments (PSA) are performed on mainline sec6ons where a spill has occurred. A mainline sewer pipe is televised within two (2) working days of an overflow or back up. Upon review of the CCTV assessment, a High Frequency schedule may be assigned to the mainline sec6on, or a Point Repair may be scheduled.

Where necessary, a mainline is added to the CIP list for replacement/rehabilita6on. In the event the mainline pipe sec6on is added to the CIP list, the cleaning frequency will be increased, and that higher frequency cleaning schedule will be implemented un6l rehabilita6on and/or replacement is completed.

The District’s Siphons are on a 1-month cleaning schedule all other pipes are on a 3-, 6-, or 12-month schedules. Addi6onally, the schedules have been grouped by Basin so to reduce travel 6me and make cleaning processes more efficient.

Sewer Cleaning Results Matrix - The District collects all observa6ons made by its sewer cleaning crews regarding the extent and nature of materials removed during the cleaning process. The observa6ons are recorded in the District’s computerized informa6on management system. The District maintains or changes the frequency of its High Frequency PM Cleaning Program for a Sewer Line Segment based on the Sewer Cleaning Results and CCTV inspec6on. See Matrix below in accordance with the sec6on labeled “Ac6on.” Changes in cleaning frequency based upon cleaning results and or CCTV data shall be determined by the 112

OPERATIONS AND MAINTENANCE PROGRAM

Page 33 of 57 ends

District Collec6on System Opera6ons Superintendent or Assistant Superintendent and no reduc6on in cleaning frequency shall be made in a Sewer Line Segment with a previous history of spills without the approval of the District Collec6on System Assistant Opera6ons Superintendent, or Opera6ons Superintendent.

Root Control - Roots are removed mechanically, through high pressure hydro-jeQng and chain flailing during regular cleaning. Every effort is made to trap roots physically at the downstream manhole to remove them from the collec6on system. In 2010, the District funded and implemented a chemical root control treatment system in areas of the District with a history of root intrusion and difficult access. The root control treatment reduces the need for frequent visits by the Hydro-jet crews and significantly reduces spills in these areas.

This cost-effec6ve approach, which allowed cleaning crews to be more produc6ve in cleaning more pipeline in other areas of the District, will be con6nued in the future.

Odor Control - The District has few odor complaints – less than five per year. However, when odor complaints are received, District crews respond with an on-site inves6ga6on and improvements, if needed. For example, the District had been working with an isolated odor issue at the Corte Madera pump sta6on emana6ng from the Village Square Li\ Sta6on. In late 2016 the flows from the (former) Corte Madera Pump Sta6on were redirected to the new Sausal Vista Pump Sta6on. The District currently treats the Village Square pump sta6on with Helix-Commander odor control product to control the odors and H2S. Its effec6veness is measured regularly with the District’s OdaLogger Unit.

Inves6ga6on of Customer Complaints - The District places high priority on responding to customer complaints about sewer service. Complaints are generally related to sewer stoppages, overflows, or, less frequently, odors. Detailed informa6on about communica6on and the District’s response procedures are included in the District’s SERP, which is discussed further in Element 6. Response is performed by the field crews during work hours and the on-call staff member during nonworking hours. Response includes making a field assessment of the complaint and taking necessary ac6on(s) required to resolve the problem.

Increased preventa6ve maintenance may be implemented if the problem is mainline related to minimize recurrence of the issue. The District maintains a customer service survey process and regularly reviews customer service comments so that employees know how the District’s work is regarded by the public.

Customer Survey forms are reviewed regularly in an effort to achieve con6nuous improvement in customer service.

Condi6on Assessment - The District conducts closed circuit television (CCTV) inspec6ons of its sewer facili6es to evaluate their condi6on and iden6fy needed increased preventa6ve maintenance, repairs and rehabilita6on. This ac6vity has been further augmented by the purchase of two (3) Pipe Hunter Je?er Unit that performs CCTV during preventa6ve maintenance opera6ons which ensures the line is cleaned properly.

CCTV inspec6ons of the collec6on system are performed on a six (6) year cycle by District crews. In addi6on to inspec6on of exis6ng pipelines, the District performs CCTV inspec6on on newly installed pipelines and inspects pipelines which have experienced spills to assess cause of the overflow and to determine the best method and frequency of cleaning or needed repair to prevent a repeat spill. The District’s CCTV equipment records inspec6on informa6on that is stored in CMMS so\ware. CCTV data is then transferred to the District’s CMMS database. The District assigns condi6on ra6ngs as set forth by the Pipeline Assessment & Cer6fica6on Program (PACP) to each of the inspected pipelines using the protocol established by the Na6onal Associa6on of Sewer Service Companies (NASSCO). The District uploads pipeline condi6on ra6ngs on an ongoing basis into Lucity.

CCTV reports and videos, together with field observa6ons, form the basis for establishing needed system maintenance and repairs. Results are logged using fault (defect) codes and a numerical ra6ng scale (with 113

weights assigned to each type of defect). The ra6ngs reflect the rela6ve severity of the observed defects.

The table below is used as a guide for the selec6on of pipes for sewer repair or rehabilita6on.

Pipe Repairs - Point repairs are completed by District crews. Larger repairs are designed and compe66vely bid for construc6on through the District’s Capital Improvement Program. Other factors are considered for placing a pipe segment on the CIP such as:
• Maintenance history,
• Number of defects within a segment,
• Spills history if any,
• Impact should a spill occur, and
• Remaining useful life of pipeline.

Service Laterals - All side sewers, from the connec6on to the District public sewer to the property served, are the property of, solely owned by, and sole responsibility of the property owner. However, the District does, as a courtesy, provide blockage clearing services from a conforming property line cleanout to the mainline sewer when requested by the property owner.

WBSD par6cipates in the Bay Area Clean Water Agency (BACWA) public outreach commi?ee and, as a member of this group, has helped to develop a handout for plumbers that apply for permits to perform sewer lateral repairs and/or replacements. In addi6on, the District provides standard details for repair and replacement work that can be used by plumbers, contractors, or homeowners. This informa6on is available on the District’s website and at the District’s front office counter. 114

7. Sewer Pipe Blockage Program

WDR REQUIREMENTS
A?achment D-7 (pg. D-7)
“The Sewer System Management Plan must include procedures for the evaluaon 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 jusficaon in its Plan for why a program is not needed.

The procedures must include, at minimum:
• An implementaon plan and schedule for a public educaon 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 facilies and/or addional facilies needed to adequately dispose of substances generated within a sanitary sewer system service area;
• The legal authority to prohibit discharges to the system and idenfy 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 pracces requirements, recordkeeping and reporng requirements;
• Authority to inspect grease producing facilies, enforcement authories, and whether the Enrollee has sufficient staff to inspect and enforce the fats, oils, and grease ordinance; • An idenficaon of sanitary sewer system secons subject to fats, oils, and grease blockages and establishment of a cleaning schedule for each secon; and • Implementaon of source control measures for all sources of fats, oils, and grease reaching the sanitary sewer system for each secon idenfied above.”

COMPLIANCE
In many sanitary sewer collec6on systems, Fats, Oils, and Grease (FOG) is known to be a significant cause, and or contributor, of sewer blockages in pipe and the cause of opera6onal disrup6ons and damage to sewage pump sta6ons. Although service areas that include commercial and ins6tu6onal food service establishments (FSEs) are obvious sources of FOG, residen6al communi6es, especially those of medium and high-density mul6-family residences, can also be a significant source of FOG. It is the purpose of the FOG Control Program to ensure all customers in our service area are following the District Ordinance, and state and federal requirements, to prevent sewage overflows caused by FOG related blockages in our sewer collec6on system.
• Outreach and educa6on are a significant component of the District’s environmental programs.

Newsle?ers with descrip6ons of BMPs for food facili6es are distributed to educate the FSEs about minimizing the impact of FOG on the collec6on system.

Outreach for residents has also been a component of the program. East Palo Alto residents have received inserts educa6ng them on the problems caused by improper disposal of FOG to the sewer 119

system. Messages include simple BMPs such as disposing of used cooking oils and grease in the trash a\er placing them in sealed containers or absorbing them onto paper towels. • The District’s Ordinance dated December 2024 “Establishing Rules and Regula6ons that Apply to Discharges of Wastewater Containing Fats, Oils, and Grease (FOG) Conveyed to the Wastewater Facili6es from any Commercial or Ins6tu6onal Food Service Establishment”, Sec6on 05 Maintenance Requirements, (B) requires grease haulers be licensed and to dispose of accumulated grease at an approved recycling or disposal site. Pumping schedules are site specific and based on grease interceptor performance.

Grease and other pipe blocking substances collected during the course of rou6ne system maintenance is disposed of at the WBSD FERF facility, on an as-needed basis. • The legal authority to prevent discharges to the collec6on system is provided in the District’s Sewer Use Ordinance 39 and City of Palo Alto Sewer Use Ordinance 16.09. • The requirement to install and maintain grease removal devices is provided in District Ordinance “Establishing Rules and Regula6ons that Apply to Discharges of Wastewater Containing Fats, Oils, and Grease (FOG) Conveyed to the Wastewater Facili6es from any Commercial or Ins6tu6onal Food Service Establishment”, Sec6on 04 Grease Control Device requirements, Sec6on 05, Maintenance Requirements, Sec6on 06, Kitchen BMPs, and Sec6on 07, Recordkeeping Requirements.

• The Authority to inspect grease producing establishments is provided in the District Ordinance dated December 2024.
• Ethe District has had an ongoing preventa6ve maintenance program that includes regular cleaning and inspec6ons of more than 35 miles of collec6on system piping. The District has iden6fied areas. requiring more frequent cleaning based on past experience and upon data collected during CCTV inspec6ons.
• West Bay Sanitary District (WBSD) performs facility inspec6ons for the District. WBSD, Water Quality Department, has two Source Control Inspectors who perform facility inspec6ons of all commercial and industrial businesses within the District’s sphere of influence, which includes East Palo Alto Sanitary District. One of the func6ons of this department is to ensure that FOG-related businesses (restaurants, food prepara6on facili6es, vehicle service facili6es, etc.) are inspected on a regular basis and maintain consistent compliance with the District’s Code of General Regula6ons, and state and local ordinances related to FOG.

The FSEs are categorized by their poten6al to contribute FOG to the collec6on system or cause other problems such as storm water viola6ons. Facili6es located in hot spots or that have been problema6c will be addressed first and receive more frequent inspec6ons. Bringing some facili6es into compliance may be a lengthier process requiring mul6ple follow-up inspec6ons. Some facili6es 120

• Capacity assessment and design criteria;.
• Priori6za6on of correc6ve ac6ons; and
• A capital improvement plan.”

8.1. System Evalua6on and Condi6on Assessment

WDR REQUIREMENTS
A?achment D-8.1 (pgs. D-7/D-8)
“The Plan must include procedures to:
• Evaluate the sanitary sewer system assets u6lizing the best prac6ces and technologies available; • Iden6fy and jus6fy the amount (percentage) of its system for its condi6on to be assessed each year; • Priori6ze the condi6on assessment of system areas that:
 Hold a high level of environmental consequences if vulnerable to collapse, failure, blockage, capacity issues, or other system deficiencies;
 Are located in or within the vicinity of surface waters, steep terrain, high groundwater elevaons, and environmentally sensive areas;
 Are within the vicinity of a receiving water with a bacterial-related impairment on the most current Clean Water Act secon 303(d) List.

• Iden6fy system assets vulnerable to direct and indirect impacts of climate change, including but not limited to: sea level rise; flooding and/or erosion due to increased storm volumes, frequency, and/or intensity; wildfires; and increased power disrup6ons.”
123

Page 44 of 57 ends

COMPLIANCE
The above requirements are addressed below:
• The assessment of a collec6on system involves pipelines and manholes. The assessment of pipeline condi6on is the most significant condi6on assessment responsibility the District has. It is of key importance to regularly perform pipeline condi6on assessments to ini6ally establish a condi6on baseline and to monitor condi6on changes over 6me.
 The District contracts maintenance ac6vi6es to West Bay Sanitary District (WBSD). It is an6cipated all gravity pipes will be inspected by Spring of 2026, as WBSD is pursuing an aggressive one year schedule to complete their ini6al baseline assessment. Upon comple6on, the CCTV findings will be evaluated to determine pipe performance for each manhole-to-manhole pipe segment. This evalua6on will be used, along with historic performance data, cleaning intervals and findings, and repair and rehabilita6on schedules to determine the op6mal CCTV inspec6on return interval moving forward. • The District will use the findings from the condi6on assessment endeavor (men6oned above) to determine pipe performance and then iden6fy por6ons of the sewer system that are close to sensi6ve areas, such as surface waters, schools, hospitals, and may place a higher priority on these assets for public health, safety and environmental reasons.
• The District u6lizes the NASSCO PACP defect coding system to rank defects found during CCTV inspec6ons of gravity mains. Manholes are visually inspected and documented by CCTV crews, employing a top-down inspec6on method, during rou6ne CCTV ac6vi6es.

Areas iden6fied as possibly suscep6ble to erosion or landslides and creek crossings pipes, including siphons are visually inspected a\er significant rain events.

As a ma?er of prac6ce, District crews are trained to monitor system assets for spills, sink holes, loose or ill-fiQng lids, construc6on ac6vi6es, etc., while driving and performing their work throughout the service area.
• The District is not aware of exfiltra6on from the system. Any discoveries of exfiltra6on would be considered high priority will be addresses accordingly. • The District maintains records and documenta6on of all system evalua6on and condi6on assessment inspec6ons and ac6vi6es in its Lucity CMMS.
• A rise in sea level could lead to flooding from King Tide events. This has been mostly mi6gated by the raising of levees in the surrounding area. The poten6al for damage caused by wildfire is remote and related power outages would not affect District opera6ons, as all flows are conveyed by a gravity system. The District will evaluate the poten6al impacts from climate change at least every three years during SSMP Audits.

“The Plan must include procedures to idenfy system components that are experiencing or contribung to spills caused by hydraulic deficiency and/or limited capacity, including procedures to idenfy the appropriate hydraulic capacity of key system elements for:
• Dry-weather peak flow condions 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
• Idenfy the major sources that contribute to the peak flows associated with sewer spills.

The capacity assessment must consider:
• Data from exisng system condion assessments, system inspecons, system audits, spill history, and other available informaon;
• Capacity of flood-prone systems subject to increased infiltraon and inflow, under normal local and regional storm condions;
• Capacity of systems subject to increased infiltraon 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 condions, and updated design storm and wet weather events; and
• Necessary redundancy in pumping and storage capacies.”

COMPLIANCE
The District updated its East Palo Alto Sanitary District Master Plan in 2015 AND issued the Addendum to Master Paster Plan in 2021. The master planning effort evaluated the capacity of the exis6ng sanitary sewer system assets and provided capacity design criteria for future assets. Projects within the District's service area are primarily to serve future redevelopment. The District includes impact fees within the connec6on fees to help contribute to future downstream projects needed for extra pipe capacity.

By metering, the District periodically monitor’s the flow in its sanitary sewer system to iden6fy capacity deficiencies and to monitoring the quan6ty of inflow and infiltra6on present.

The capacity-related design criteria are included in the SSMP Design and Performance Provisions.

Not all of the requirements listed above were considered during this evalua6on, as the evalua6on was performed prior to the issuance of these regula6ons. Future capacity assessments will be in complete compliance.

COMPLIANCE
The District includes publicly funded capacity enhancement projects in its Capital Improvement Program.

The Capital Improvement Program includes recommended projects to address capacity deficiencies in the system. The capital improvement projects planned for the next 15 years are described within the Master Plan (Appendix M).

The schedule for the District’s capacity enhancement projects is included in the District’s CIP. The CIP in the 2021 Addendum iden6fies pipelines that require repair and replacement to prevent manhole surcharging and poten6al SSOs. It also iden6fies increases in capacity needed to account for future developments based on modified zoning designa6ons. Pipeline improvements are iden6fied, and the sequence of construc6on will be determined based on District’s observa6ons of exis6ng pipe condi6ons and new development needs.

WDR REQUIREMENTS
A?achment D-9 (pg. D-9)
“The Plan must include an Adapve Management secon that addresses Plan-implementaon effecveness and the steps for necessary Plan improvement, including:
• Maintaining relevant informaon, including audit findings, to establish and priorize appropriate Plan acvies;
• Monitoring the implementaon and measuring the effecveness of each Plan element;. • Assessing the success of the prevenve operaon and maintenance acvies:
• Updang Plan procedures and acvies, as appropriate, based on results of monitoring and performance evaluaons; and
• Idenfying and illustrang spill trends, including spill frequency, locaons, and esmated volumes.”

COMPLIANCE
The above requirements are addressed below:
• The District maintains accurate and relevant inspec6on and maintenance records for the collec6on system. Much of the documenta6on today is maintained electronically, which allows for ease of access and analysis. This helps District staff to make sound decisions and priori6ze ac6vi6es when dealing with the rou6ne and the unexpected.
• Monitoring of the District’s SSMP focuses on each element in terms of its implementa6on and effec6veness. The SSMP has been designed to include key performance indicators for each element, which are used to measure effec6veness. In addi6on, implementa6on responsibili6es are included for each element to help ensure the SSMP is being implemented as intended. • The District assesses the success of maintenance and opera6on ac6vi6es by ensuing ac6vi6es are being performed as expected, by monitoring actual outcomes compared to intended outcomes, as well as monitoring spill trends.
• The District is commi?ed to con6nuous 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 should be considered as a dynamic document and may require upda6ng on a more frequent basis.

Rou6ne changes to administra6ve informa6on, notwithstanding, minor changes will likely be required to address improvements iden6fied through the SSMP Audit or through modifica6ons required as condi6ons change.
• The District monitors spill trends, at a minimum every three years during required audits, u6lizing the CMMS database, inspec6on records and CIWQS data. These resources are helpful in planning and programing work, and adjus6ng as needed, enabling the District to be adap6ve and capitalize on lessons learned.

EAST PALO ALTO

SANITARY DISTRICT

STAFF REPORT
DATE: July 29, 2025
TO: Honorable Members of the City of East Palo Alto City Council, Governing Board to the East Palo Sanitary District, a Subsidiary of the City of East Palo Alto
VIA: Melvin E. Gaines, General Manager
BY: Humza Javed, District Engineer
Nancy Murguia, Management Analyst
SUBJECT: 2025 Sewer System Master Plan
Recommendation
Adopt a resolution:

1. Approving the 2025 Sanitary Sewer System Master Plan; and

2. Finding that the proposed action being considered by the City Council is exempt from the California Environmental Quality Act (CEQA) because it requires the implementation of management operations programs and plans to enhance and protect the environment by limiting the occurrence of SSOs in the City. (CEQA Guideline section 15308).

Further, implementation of the proposed action may require the installation of minor sewer system facilities which will involve either minor alterations to existing facilities, or repair or replacement of existing facilities involving negligible or no expansion of sewer capacity, and as such, are exempt from review under CEQA Guidelines sections 15301 and 15302.

Alignment with City Council Strategic Plan
This recommendation is primarily aligned with:

Public Infrastructure and Utilities
Background
On November 15, 2023, the San Mateo Local Agency Formation Commission (LAFCo) unanimously approved the City of East Palo Alto’s application to designate the East Palo Alto 138
EPASD BOARD CONSENT ITEM 10.2
Sanitary District (EPASD or the District) as a subsidiary district of the City. The reorganization took effect on October 1, 2024, when the City Council assumed governance of EPASD. EPASD remains a legally separate entity from the City, and its assets are kept distinct.

The City of East Palo Alto has a contract with Freyer & Laureta, Inc. (F&L) to provide engineering support services for EPASD (for which the EPASD reimburses the City), including development of a 2025 Sanitary Sewer System Master Plan (Master Plan). F&L has been working on the Master Plan since the beginning of this year, and it has provided progress updates on the Master Plan development at three previous EPASD Advisory Committee meetings.

At the June 25, 2025, EPASD Advisory Committee meeting, the Advisory Committee recommended approval of the Master Plan to the EPASD Board.

Additionally, the Planning Commission reviewed conformance of the projects in the Master Plan with the City’s General Plan at the July 14, 2025, Planning Commission meeting.

The Master Plan was presented to the EPASD Board on July 15, 2025. The Board directed staff to postpone the item till the July 29, 2025, City Council meeting in order to allow the development community additional time to provide input.

Analysis
The Master Plan is intended to provide the District with an overall plan for sanitary sewer infrastructure improvements over the next twenty years to maintain sanitary sewer system reliability and support anticipated development within the City.

The scope of the Master Plan includes:
 Summarizing and describing the District’s service area and existing sanitary sewer system.
 Assessing current and projected sanitary sewer demands, including identifying potential vulnerabilities to inflow and infiltration (I/I) during wet weather events.  Establishing performance, operational, and reliability criteria for evaluating system capacity and identifying rehabilitation and replacement needs.  Constructing, calibrating, and evaluating a new hydraulic model to assess the system’s capacity to convey existing and future flows, including Average Dry Weather Flow (ADWF) and Peak Wet Weather Flow (PWWF), and identifying potential capital improvements.
 Preparing a comprehensive evaluation of the system’s capacity, redundancy, resiliency, and rehabilitation and replacement needs over a 20-year planning horizon.
 Verifying the need, sizing, and prioritization of planned sanitary sewer system improvements.
139
EPASD BOARD CONSENT ITEM 10.2
 Developing a 20-year, risk-based Capital Improvement Program (CIP) that prioritizes existing capacity deficiencies and plans for future improvements based on system needs and risk of sanitary sewer overflows.
 Developing a preliminary cash flow analysis to support long-term financial planning and inform Board decision-making.

The Draft 2025 Master Plan is included as an attachment to this staff report. Additionally, the final updated copy of the Master Plan will live on the City website at the following link:
https://www.cityofepa.org/sanitary/page/sanitary-district-documents Projects
As part of the Master Plan, projects were identified for the next twenty years. Projects are categorized as follows:
 Category 1 projects address existing capacity related deficiencies that represent the highest priority projects. These projects address existing capacity deficiencies.  Category 2 projects address future development capacity related deficiencies and would be implemented in phases as new development projects move through the City’s Planning and Building approval processes.
 Category 3 projects are those that address structural deficiencies and aging infrastructure with the highest priority projects to be addressed over a twenty-year horizon with ongoing annual funding to eventually replace all of the sanitary sewer pipelines within the collection system. These projects were identified by Sierra West (EPASD’s previous engineering consultant) as those that exhibit the worst structural conditions and can be implemented in phases. Following completion of high priority projects, the remaining pipeline segments (approximately 143,000 linear feet) will be replaced over a 20-year period.

Detailed project information is included on the project summary sheets in the SSMP.

Staff provided a comprehensive presentation of the Master Plan during the July 15, 2025, Board meeting.

Fiscal Impact
There is no direct fiscal impact with the adoption of this plan. The EPASD Board will need to adopt a separate capital budget to proceed with the individual projects. 140

ES EXECUTIVE SUMMARY
ES.1 Background and Introduction
The East Palo Alto Sanitation District (EPASD) was first established in 1939 in the southern corner of San Mateo County and borders Santa Clara County. Both the Cities of East Palo Alto portions of Menlo Park and are part of the EPASD’s service area.

The purpose of this Master Plan was to re-establish the EPASD model in new software, provide an updated Capital Improvement Program (CIP) along with a rate and impact fee. This Master Plan is an update to EPASD’s previously completed Master Plan in 2015 and its 2021 addendum.

ES.2 Land Uses
EPASD serves Cities of East Palo Alto and Menlo Park with a gravity-based sewer collection system covering approximately 1,230 acres (1.92 square miles) as shown in Figure ES.1. The system includes approximately 33 miles of sewer pipelines, primarily 6-inch vitrified clay pipes (VCP), with larger mains up to 30 inches in diameter. A major infrastructure component is the siphon under San Francisquito Creek, which was realigned in 2017 with two parallel 22-inch high-density polyethylene (HDPE) pipes.

Downstream of the syphon, sewer system is conveyed to the Palo Alto Regional Water Quality Control Plant (RWQCP) for treatment.

EPASD operates and maintains the collection system in accordance with the requirements of the State Water Resources Control Board, as administered through the Statewide SSO Waste Discharge Requirements and RWQCB Sewer System Management Plan guidelines.

The City of East Palo Alto’s 2035 General Plan, adopted in 2017, introduced land use changes to support balanced development across residential, commercial, and recreational uses. In 2024, the Ravenswood Specific Plan was adopted, which provided further refinement in the eastern portion of the city, enhancing details for mixed-use areas. These land use updates and other known developments were incorporated into system model. The land use maps are included in Appendix A.

ES.3 Sanitary Sewer Flow and System Analysis
Sewer flow estimates were derived using updated hydraulic modeling inputs, historic monitoring data, and land use assumptions. The methodology builds on the foundational work from the 2015 Master Plan and incorporates current Geographical Information System (GIS) data, flow monitoring studies, and zoning projections.

The flow projections for developments were calculated using a multi-step process based on billing records, zoning designations, and equivalent dwelling units (EDUs). Key elements of the process included:
• Estimating existing flows using 2019 billing data and a baseline of 200 gallons per EDU per day, consistent with WBSD practices.
152
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. ES-2 • Projecting future flows using zoning densities and Floor Area Ratios (FAR) from the 2035 General Plan and Ravenswood Specific Plan.
• Based on 2011-2012 Sanitary Sewer Flow Monitoring Inflow/Infiltration Study by V&A Consulting (V&A Flow Monitoring), the peaking factors were applied to calculate peak wet weather flows (PWWF) from average dry weather flows (ADWF).

153
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. ES-3 ES.4 Hydraulic Model Development
A hydraulic model was used to evaluate the current and future performance of the sewer system sewer system collection system. This model represents a tool used to support decision making for the ongoing improvement and maintenance of the system. The model incorporates physical and operational characteristics of the system and simulates key hydraulic parameters such as flow, velocity, depth, surcharge conditions, and hydraulic grade lines. The model was rebuilt from the outdated Hydra 7 platform to Bentley’s SewerGEMS software. The new model was developed using EPASD’s GIS database, archived field data, and updated infrastructure records. Validation against historical flow data confirmed the reliability of the SewerGEMS model, making it the analytical foundation for evaluating existing and future system capacity needs.

The three planning scenarios included the following:
• Scenario 1: 2025 Existing Conditions: The model was updated to reflect constructed developments and sewer improvements as of 2025. The projects included are Light Tree Apartments, University Plaza Phase 1, and 1950 Bay Road. The ADWF and PWWF were calculated and analyzed to assess the current system's capacity and identify deficiencies. • Scenario 2: 2035 Conditions: Scenario 2 will be described as 2035 Conditions, which include the land use changes from the 2035 General Plan and Ravenswood Specific Plan. • Scenario 3: 2035 Enhanced Conditions: Scenario 3 will be described as the 2035 Enhanced Conditions, which include the 2035 General Plan, Ravenswood Specific Plan, and Planned Developments. The planned developments include University Plaza Phase 2, Weeks Street Townhomes, and others.

This sanitary sewer system's performance was evaluated under wet weather conditions using a 10- year, 24-hour design storm, as defined by NOAA, to assess system capacity and predict sanitary sewer overflows (SSOs).

The 2025 Master Plan revises previous pipeline design criteria, replacing the depth-to-diameter (d/D) ratio with a freeboard-based standard. Under this updated criterion, all new or replacement pipelines are required to maintain a minimum of four feet of freeboard under design storm conditions. In instances where the pipe depth is less than four feet and the freeboard criterion cannot be applied, the system must demonstrate that no SSOs will occur under modeled conditions.

ES.5 Hydraulic Capacity Analysis Results
Hydraulic modeling was conducted for the three scenarios providing key insights into the current and future performance of the EPASD’s sanitary sewer system (Figures 5.1, 5.2, and 5.3). Based on the expected surcharge in current and future conditions, current and future capacity improvements are needed to accommodate peak wet weather flows.

Major observations within the model include:
154
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. ES-4 • Modeled 2025 current conditions do not predict SSOs and surcharging exists in some areas exceeding the design criteria.
• Modeled 2035 Conditions and 2035 Enhanced Conditions experience SSOs with surcharging in some areas exceeding the design criteria.
• There are both existing customer and developer-related capacity improvements required • The system has hydraulic limitations due to relatively flat existing topography, pipe slopes, and the absence of pump stations.
• Low flow velocities under both current and future dry weather conditions do not exceed 2 ft/s, which will require ongoing maintenance and monitoring.

ES.6 Pipeline Capacity and Condition Assessment
The recommended improvements for the sanitary sewer system have been grouped into four prioritybased categories. These categories address both existing and future deficiencies related to hydraulic capacity, structural condition, and system longevity. A summary of each category is provided below, and results are provided in Table ES.1 and mapping of categories 1-3 are presented in (Figure 6.1 through 6.5).

2, Excludes pipelines where developers and existing customers share responsibility.

Highlights: Category 1 and 3A deficiencies are grouped with the duties of current customers to fund improvements.

Category 2 Improvements are developer related improvements. Category 3B lines represent ongoing maintenance needs by all customers.

ES.7 Capital Improvement Program
The CIP was developed based on the deficiency category classifications. Categories 1 and 3A represent the most urgent needs due to existing hydraulic and structural deficiencies. Category 2 projects address future capacity needs related to anticipated development and should be reviewed regularly in coordination with the EPASD as growth occurs. Where practical, structurally deficient pipes from Category 3A were incorporated into Category 1 or 2 projects to maximize efficiency and reduce construction overlap.
155
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. ES-5 The CIP projects are broken down by Category, a summary can be seen in Table ES.2. Additional detail is found in Tables 7.1 through 7.5 mapped out in Figures 7.1 through 7.4. A breakdown of each CIP project is found in Appendix E.

The project estimates should be evaluated alongside other infrastructure capital planning efforts within the City.

1. Portions of the project contain other category pipes to maximize construction efficiency. Work should be performed over the next 4 years funded by reserves and sewer service charges.

2. Principally developer-related projects.

3. The remaining portion of the sewer system 74% for existing VCP is suggested to be replaced over a 25-year period based on available funds. The OPPC for the remaining aging infrastructure will be approximately $4.3M/yr (6,000LF/yr), with an overall total of $107M. It is important to note that this cost is based on slip lining repair and partial replacement only.

ES.8 Rate and Impact Fee Study
As part of the EPASD’s Master Plan update, a sewer service charge has been developed to support funding maintenance of the existing system. This rate is presently set at $660, and the addition of an annual increase of 5% be applied to the fund the extensive deferred maintenance in the system.

Secondly, a revised impact fee has been developed to reflect newly identified CIP projects and current system capacity conditions. The proposed impact fee is $7,800 per EDU plus an annual 5% escalation, reduced from the previous fee of $10,621. The cost includes:
• Developer’s Share of Capacity Assurance: 25 percent of the costs are associated with existing capacity assurance improvements that will benefit future developments. • Developer’s Improvement: 100 percent of the costs related to future capacity deficiencies based on new development demands.
• Buy-In Treatment Cost: A buy-in cost of $5 million per 1.0 million gallons per day (MGD) of treatment capacity.

1.1 Background and Project Objectives
The East Palo Alto Sanitary District (EPASD) was established in 1939 in response to the growing development in the East Palo Alto area. It was created under the Sanitary District Act of 1923 (Health and Safety Code Section 6400 et seq.), which allowed for the formation of special districts to provide sewer system collection and treatment services. Initially, the district's sewer lines were built as part of a Works Progress Administration (WPA) project during the New Deal era. Construction of these facilities began after a treatment agreement was reached with the City of Palo Alto in 1940, and EPASD's infrastructure was officially operational on September 8, 1942.

EPASD serves a portion of the cities of East Palo Alto and Menlo Park, in San Mateo County, and its sewer system collection system directs sewage to the Palo Alto Regional Water Quality Control Plant for treatment. The district historically operated as an independent special district, meaning it is governed separately from city governments. A five-member elected Board of Directors oversees its policies, while employees carry out daily operations.

As of October 1, 2024, EPASD became a subsidiary district of the City of East Palo Alto (City). The establishment of EPASD as a subsidiary district to the City was approved by the San Mateo Local Agency Formation Commission (LAFCo) on November 23, 2023, and finalized on September 16, 2024.

LAFCo’s approval of the subsidiary district recognized the need for improved transparency in EPASD governance and sustainable and efficient operation of EPASD.

The EPASD system includes the operation and maintenance of over 33 miles of sewer pipelines, ensuring sewer system collection for thousands of residents in its service area. As a subsidiary district of the City, EPASD will continue to operate with the City Council as the Board of Directors and the City Manager as General Manager. The City has contracted with West Bay Sanitary District (WBSD) for the day-to-day operations of EPASD.

The previous EPASD Sewer Master Plan, completed in 2015 and updated via addendum in 2021, now requires a full update. As EPASD is currently a subsidiary district, the City is initiating a new Sewer Master Plan to support a comprehensive Capital Improvement Program (CIP), including a timeline for implementation. The Master Plan update will:
• Identify areas of needed improvement within the existing sewer system as of 2025. • Determine capacity upgrades required to serve future growth based on 2035 General Plan, the Ravenswood Specific Plan, and approved redevelopment projects. • Confirm pipeline renewal and replacement identified by EPASD’s prior condition assessment program.
• Develop potential CIP alternatives, including conceptual opinions of probable project cost and implementation timelines.

FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 2-1 2 Land Uses
Section 2 summarizes EPASD’s existing sewer system system, service area, and land use conditions.

The information was compiled through a review of previous studies, available documents, and data provided by EPASD.

2.1 Existing Sewer System
EPASD provides sewer system collection service to portions of the communities of Menlo Park and East Palo Alto, located in San Mateo County, within the San Francisco Bay Area. EPASD’s service area is primarily residential with a few commercial and industrial parcels.

As shown in Figure 2.1, EPASD service area encompasses nearly 1,230 acres or 1.92 square miles.

The collection system operates as a gravity sewer network, with approximately 61% of the existing pipelines consisting of 6-inch diameter lines. Larger collector lines range between 8-inch to 30-inches in diameter. The system includes a siphon beneath the San Francisquito Creek, which was realigned in 2017 with two parallel 22-inch high-density polyethylene (HDPE) pipes.

EPASD’s sewer system collection system consists of approximately 33 miles of gravity sewer pipelines. Historically, manholes were constructed using brick and mortar, and pipelines were constructed with vitrified clay pipe (VCP).

EPASD operates and maintains the collection system in accordance with the State Water Resources Control Board, under the Statewide SSO Waste Discharge Requirements and the RWQCB Sewer System Management Plan guidelines. The collected sewer system is conveyed to the Palo Alto RWQCP for treatment and ultimate discharge to the San Francisco Bay.

All known SSOs that have been reported were due to maintenance issues. WBSD is currently conducting ongoing system maintenance and inspection efforts.

2.2 Population Served & Land Use Characteristics
As a part of the 2015 Masterplan, land use information was compiled from multiple sources for the communities served by EPASD. The following data sources were used to characterize the population and land use within the service area:
• Land Use Database – Existing land use data in Geographical Information System (GIS) • General Plan Information – Additional land use data provided by the City • Aerial Photographs – Reviewed to identify parcels and land use characteristics within the service area.
159
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 2-2 In 2017, the City adopted the 2035 General Plan, which outlines the City’s vision for development and growth throughout the year 2035. The General plan includes a series of land use changes to balance the residential, commercial, and recreational spaces throughout the city.

The key changes within the 2035 General Plan include:
• Land use modifications occurred along University Avenue between Bay Road and Donohoe Street, as well as around the existing Target shopping center. • Residential zoning changes within the Ravenswood Business District were modified from lowdensity and commercial to high-density along Maple Street. • University Avenue west of Highway 101 include changes from commercial to office, mixed-use, and medium-density residential.

In 2024, the City adopted the Ravenswood Plan, which is the eastern portion of the city. The plan builds on the 2035 General Plan by providing a more detailed framework for future land use developments for the mixed-use areas within Ravenswood.

The land use changes in both the 2035 General Plan and Ravenswood Plan were incorporated into the 2025 Master Plan and the hydraulic model to reflect the anticipated future flows. The land use changes in both these plans are provided in Appendix A.

2.3 Existing Collection System Facilities
Since the completion of the 2015 Masterplan, EPASD has implemented several CIP projects to upgrade the existing sewer system. The upgrades to the system involve replacing the aging infrastructure with improved materials for both manholes and pipes. All new manholes were constructed with precast concrete, and new pipes were constructed with plastic pipe such as polyvinyl chloride (PVC) or HDPE.

The sewer system improvements completed since the 2021 Master Plan Addendum are illustrated in Figure 2.2. The improvements include 6,688 linear feet (LF) of newly installed sewer pipe.

The following is a summary list of the scope of work and highlight the improvements implemented across the two different projects.

1. Light Tree (2021)
As part of a private development project in 2021, the sewer infrastructure was improved on O’Connor Street, Pulgas Avenue, and Clarke Avenue. The project improvements included:
• Installing 9 new manholes.
• Reconstructing 1 manhole.
• Installed or replaced:
o 132 LF of 6-inch PVC.
o 76 LF of 10-inch PVC.
o 297 LF of 12-inch PVC.
o 1,310 LF of 16-inch PVC.
o 1,149 LF of 18-inch PVC.

2. Sanitary Sewer Replacement Project (2023)
As a part of the 2023 CIP project, multiple areas of EPASD sewer system were replaced/repaired. The projects occurred along Beech Street, Clarke Ave, Green Street, and O’Connor Street. The improvements included:
• Installing 7 new manholes.
• Rehabilitating 21 manholes.
• Installing or replacing:
o 764 LF of 30-inch PVC.
o 1,021 LF of 24-inch PVC.
o 1,323 LF of 20-inch PVC.
o 395 LF of 14-inch PVC.
o 486 LF of 18-inch PVC.

FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 3-1 3 Sanitary Sewer Flow Analysis
Section 3 summarizes the background and methodology used to determine existing and future dry weather sewer system flows for input to EPASD’s collection system hydraulic model.

3.1 Infiltration and Inflow
V&A Flow Monitoring Report included a sanitary sewer flow monitoring inflow/infiltration (I&I) study in 2011-2012 for East Palo Alto. The study separated the service area into different flow monitoring sites, and the results were used to identify the average dry weather flow, peak dry weather flow, and peak wet weather flow. The flow monitoring locations are shown in Figure 3.1 with areas in Table 3.1.

The peaking factor results from the study are provided in Table 3.2.

3.2 Calculation of Flows
The V&A Flow Monitoring Report provided the data used to calculate sewer system flows for EPASD's existing hydraulic system. Based on three scenarios described later in later in this report, the following method was used to calculate the estimated additional sanitary sewer flows for each parcel. The calculated injection flows were inserted into the recalibrated 2014 Sewer Map in SewerGEMs that is further described in Section 4.

The calculation of flow injections uses a similar process as described in the 2021 Master Plan. As EPASD does not monitor flows from each individual parcel, a multiple-step process was followed to calculate the incremental additional flow by parcel. The major steps taken to estimate incremental additional flow by parcel are as follows:

1. Existing flow from each parcel was estimated and key aspects included:
a. The 2019 Tax Year Billing Charges were reviewed to identify the individual parcel billings.
b. Based on the individual billings, the Equivalent Dwelling Units (EDU) were calculated by dividing the parcel bill by $575 per EDU.
c. The calculated number of EDUs by parcel was then multiplied by 200 gallons per EDU to estimate the existing sanitary sewer flow from each parcel. This represents an update and decrease in flow per EDU, previously established at 240 gallons per EDU. This new value is in line with modern plumbing standards, other local water districts, and use of more water efficient products and landscaping trends.

2. Total flow from each parcel based on the 2035 General Plan and Ravenswood Plan’s revised zoning was then estimated:
a. The Maximum and Minimum Allowable Density and Floor to Area (FAR) ratio for each zoning category was identified in the 2035 General Plan and Ravenswood Plan. The land use characteristics for these calculations are included in Appendix A. 162
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 3-2 b. Using 50-percent of the range between maximum and minimum allowable density and FAR for each parcel, the estimated total sanitary sewer flow for non-residential was calculated using the unit flow rates from East Palo Alto Sanitary District Standard Specifications for Design and Construction of Sanitary Collection and Conveyance Facilities (Standard Specifications) report dated June 2002.

3. Lastly, total additional flow by parcel for both Average Dry Weather Flow (ADWF) and Peak Wet Weather Flow (PWWF) was calculated:
a. ADWF for existing conditions presented is subtracted from ADWF for future zoning changes based on each scenario.
b. PWWF was calculated by multiplying the ADWF for each parcel by the Sewer Basin PWWF Peaking Factor from Table 3.2. As there are no current-day studies for the I&I in the system, the peaking factor results from the V&A study were used to calculate the future PWWF flows.

3.3 Water Supply Service
As part of the verification of the predicted sewer model, F&L evaluated current drinking water imports into the service area. The City of EPA water supply is sourced from two primary channels: purchased water from San Francisco Public Utilities Commission (SFPUC) or groundwater extracted from wet wells. According to EPA’s Supply Assurance, SFPUC is required to provide an Individual Supply Guarantee (ISG) of 3.46 MGD of drinking water to the City. As detailed in Section 4.3, the projected 2035 Enhanced ADWF sewer flow for the future buildout is approximately 3.3 MGD. This indicates that the anticipated water supply exceeds the projected sewer demand, demonstrating sufficiency in meeting future needs.

3.4 Sewer System Treatment Capacity.

The Palo Alto Regional Water Quality Control Plant (RWQCP) records the total sewer system flow for EPASD and neighboring cities. The RWQCP is permitted to treat an average dry weather flow of 39 MGD. EPASD has an agreement with the RWQCP, where EPASD’s average annual flow capacity treatment allotment is 3.06 MGD, 7.64% of the RWQCP’s total capacity. 163
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 4-1 4 Hydraulic Model Development
Section 4 summarizes assumptions, items considered during model development and calibration, and key components of the completed hydraulic model. The hydraulic model was used to perform different scenarios to assess the impacts of future developments, land use changes, and any system configuration changes.

4.1 Model Components
The hydraulic model transforms information about the physical and operational characteristics of the sewer system into a mathematical model. The modeling results provide information on flows, flow depth, velocity, surcharge, and the hydraulic grade line, which were used to analyze system performance and identify system deficiencies. The model results were used to verify the adequacy of recommended or proposed system improvements.

The hydraulic model comprises a skeletonized network of nodes and conduits, which define the physical properties within EPASD’s system. The following descriptions provide information on elements used in the development of the hydraulic model. • Nodes: Nodes represent manholes and lamp holes. All flows added into the model are attached to node structures. The data required for node structures include pipe invert elevation, manhole rim elevation, and manhole diameter.
• Conduits: Conduits represent pipes that convey sewer system from one point in the system to another. The conduits include gravity pipes and siphons. The physical data for gravity pipes include pipe invert elevation, size, length, and friction factor.

4.2 Model Calibration
The 2025 Master Plan was constructed using EPASD’s GIS sewer system collection system, which includes information on the pipe material, pipe invert elevation, manhole rim elevations, pipe diameter, and pipe length. The GIS model was inserted into SewerGEMs.

As the previous sewer model developed using Hydra 7 software is outdated and no longer supported, the City approved transition to a modern platform that is better integrated with GIS. F&L rebuilt the EPASD sewer system model using SewerGEMS software using archived GIS data, databases, and field data, with a detailed ArcGIS sewer map being used as the foundation. SewerGEMS model results aligned with historical data, predicting flows, hydraulic grade lines, and surcharge locations. As the SewerGEMs model was validated, it serves as the basis for assessing system performance under current 2025 conditions and the 2035 future conditions to support updates to EPASD’s Master Plan. A detailed description of the methodology and results is provided in Appendix B. 164

4.3 Model Scenarios
Scenario 1: 2025 Conditions
The first step in analyzing the system was to update the GIS Sewer Map to reflect the current conditions of 2025. The map was updated for all sewer improvements found during the records review. The sewer system flows from the known developments built to date were calculated using the method discussed in Section 3.2. The known developments shown in Figure 4.1 include:
• 2485 Pulgas Avenue (Private Improvements)
• Light Tree Apartments
• Mid-Pen Housing (965 Weeks)
• University Plaza Phase 1
• 1950 Bay Road
The additional ADWF and PWWF by parcel are summarized in Table 4.1, with the total additional ADWF and PWWF presented at the bottom of the table. The additional ADWF is 92,574 GPD and the PWWF is 139,893 GPD. The total sewer flows for 2025 for ADWF is 1,586,080 GPD and PWWF is 5,880,153 GPD. The results from the 2025 conditions are used to assess any existing sewer capacity issues before additional development occurs within the EPASD boundaries. A detailed breakdown of the flow calculations is provided in Appendix C.

Scenario 2: 2035 Conditions
The next step in analyzing the system was to understand the capacity improvements that would be needed to serve new development based on the potential impact of the land use changes. The future conditions are described as the 2035 Conditions, which includes land use changes from the 2035 General Plan and Ravenswood Specific Plan.

Figure 4.2 shows the locations for the 2035 future flows to be injected into the model. The additional ADWF and PWWF by parcel are summarized in Table 4.2, with the total additional ADWF and PWWF presented at the bottom of the table. The additional ADWF is 1,472,639 GPD and the PWWF is 2,322,519 GPD. The total sewer flows for 2035 for ADWF is 2,966,145 GPD and for PWWF is 8,062,778 GPD.

A detailed breakdown of the flow calculations is provided in Appendix C.

Scenario 3: Enhanced Conditions
Once the additional flow based on the potential land use changes were inserted into the model, the next step was to update and analyze the system using known planned developments that were approved or in review by EPASD. The scenario represents the maximum buildout potential and is described as 2035 Enhanced Conditions, which include the 2035 General Plan, Ravenswood Specific Plan, and Planned Developments. The flows in these areas were recalculated based on the known and approved developments. The known developments shown in Figure 4.3 include:
165
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 4-3 • University Plaza Phase 2
• 2331 University Avenue
• Weeks Street Townhomes
• 2519 Pulgas Avenue
• 2535 Pulgas Avenue
• 1675 Bay Road
• 2001 Manhattan
• 2101 Runnymede
The additional ADWF and PWWF by parcel are summarized in Table 4.3, with the total additional ADWF and PWWF presented at the bottom of the table. The additional ADWF is 1,846,104 GPD and the PWWF is 2,903,896 GPD. The total sewer flows for 2035 for ADWF are 3,339,610 GPD and PWWF are 8,644,156 GPD. A detailed breakdown of the flow calculations is provided in Appendix C.

The projected ADWF under Scenario 2 and Scenario 3 is approximately 3.0 MGD and 3.3 MGD, respectively. These projections are consistent with the cumulative flow estimates presented in the Ravenswood/Four Corners Specific Plan Update SEIR – Appendix G Utility Impact Study (Utility Impact Study) prepared by Schaaf & Wheeler. The projected future cumulative demands—ranging from 3.0 to

3.3 MGD—fall within the Utility Impact Study’s estimated cumulative flow range of 3.13 to 3.33 million gallons per day (MGD).

As described earlier, EPASD’s allocated dry weather treatment capacity at the RWQCP is 3.06 MGD.

Although the projected cumulative flows slightly exceed this capacity, the planned capital improvements are expected to reduce I&I, thereby potentially mitigating peak flow impacts.

In order to ensure sufficient long-term treatment capacity, it is recommended that EPASD:
• Reestablish a collection system flow monitoring program similar to the sites presented in Table

3.1 and Figure 3.1. Continue monitoring system flows at the treatment plant as new development occurs.
• Reassess the effectiveness of I&I reduction measures following project implementation.

These actions will align system performance with treatment capacity limits and support EPASD's planning and regulatory compliance goals.
166
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 5-1 5 System Capacity Analysis
Section 5 evaluates EPASD’s sewer system collection system capacity constraints under flow conditions projected during EPASD’s design storm. This section summarizes the planning and capacity criteria, identifies predicted capacity limitations, and defines the methodology used to recommend appropriate solutions and strategies to address the identified issues.

5.1 Design Storm Criteria
Design storms are simulated rainfall events used to evaluate collection system capacity under wet weather flow conditions. A specific recurrence interval and rainfall duration define each design storm.

EPASD’s goal is to identify predicted SSOs that occur during the 10-year, 24-hour design storm.

The master plan evaluates the ability of the system to convey flows with surcharging under the selected design storm scenario. EPASD has selected as its design storm a rainfall event of 10-year recurrence intervals and 24-hour duration (10-year, 24-hour storm), as defined by the NOAA rainfall atlas.

5.2 Pipeline Hydraulic Capacity Criteria
Hydraulic capacity assessments were conducted to establish standards for identifying when pipes exceed EPASD’s acceptable surcharge limits. Under these criteria, a pipe may be considered theoretically capacity-deficient when, during PWWF conditions associated with the design storm, the water level or hydraulic grade line (HGL) rises above the top of the pipe.

While such conditions may not always result in an overflow, they indicate a potential deficiency in the pipe capacity. Exceptions to this criterion are made for siphons, which are designed to operate under surcharge conditions. All identified capacity-deficient pipelines are recommended for phased replacement, as outlined in Chapter 9, Capital Improvement Program.

In the 2015 Master Plan, pipeline capacity under projected development impacts was evaluated using the depth-to-diameter (d/D) ratio under peak dry weather flow (PDWF). This metric helped determine capital improvements needed to restore or maintain acceptable d/D values across the system. The 2025 Master Plan adopts a revised capacity deficiency criterion. The d/D method was replaced because it does not consider the effects of system aging, velocities, maintenance challenges, or non-uniform flow conditions.

In place, the revised criteria applies a freeboard-based standard that requires all pipes and manholes to maintain a minimum four-foot freeboard under design storm conditions. In areas where pipe depth is less than four feet and the freeboard criterion cannot be applied, an alternative criterion is used that no SSOs should occur under the modeled conditions.
167
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 5-2

5.3 System Capacity Deficiencies
To assess existing and future performance of EPASD’s sewer system, hydraulic modeling was conducted for three planning scenarios: 2025 Existing Conditions, 2035 Base Conditions, and 2035 Enhanced Conditions. These scenarios incorporated projected PWWF and were used to identify system deficiencies and capacity limitations.
• Scenario 1: 2025 Conditions
The 2025 Conditions were first analyzed in the model to understand the existing system deficiencies.

The PWWF discussed in Section 4.3 was add to the model. The results indicated no SSOs at any manholes; however, approximately 42,600 LF of pipeline were predicted to surcharge with less than four feet of freeboard. The results from the model are shown in Figure 5.1 and model results are provided in Appendix D.
• Scenario 2: 2035 Conditions
The next scenario that was analyzed in the model was 2035 Conditions. The PWWF flows discussed in Section 4.3 was added to the model. Under this scenario, SSOs were predicted at 22 manholes and approximately 97,600 LF of pipe segments were identified as surcharging with less than four feet of freeboard. The results from the model are shown in Figure 5.2 and model results are provided in Appendix D.
• Scenario 3: 2035 Enhanced Conditions
The final scenario evaluated incorporates 2035 Enhanced conditions, which account for planned developments and increased flow projections outlined in Section 4.3. The model predicted SSOs at 22 manholes with approximately 102,900 LF of surcharged pipe segments that do not provide four feet of freeboard. The results from the model are shown in Figure 5.3 and model results are provided in Appendix D.

FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 6-1 6 Collection System Assessment
The purpose of this section is to present an evaluation of the pipeline condition based on capacity and structural deficiencies throughout the collection system. Based on hydraulic modeling and condition assessment data, a set of recommended strategies has been developed to address identified system deficiencies. These recommendations are categorized into four groups based on the type of deficiency, each addressed in a dedicated subsection:
• Category 1: Existing Pipe Capacity Deficiencies
• Category 2: Future Pipe Capacity Deficiencies
• Category 3A: Pipe Structural Deficiencies
• Category 3B: Remaining Pipe in the Sewer System

6.1 Category 1: Existing Pipe Capacity Deficiencies
Category 1 addresses current hydraulic capacity deficiencies that exist under present-day flow conditions. As described in Section 5, the hydraulic modeling identified segments that fail to meet the minimum four-foot freeboard criteria for surcharging under PWWF.

To address the current deficiencies within the system, approximately 7,285 LF of pipe will require upsizing. The improvements not only improve deficiencies within the pipeline section itself but also reduce the HGL on upstream lines. The overall benefit of improving only 7,285 LF of pipe will bring approximately 21,058 LF of pipeline in compliance with the design criteria. Although there are remaining pipes that do not meet the design criteria, the pipes do not cause any concern of SSOs within the system.

The Category 1 projects will provide the hydraulic capacity and improve the operations of the presentday system. Figure 6.1 illustrates the locations and proposed diameter increases for each of the deficient pipes. Table 6.1 lists all the pipe segments identified and the proposed size.

6.2 Category 2: Future Pipe Capacity Deficiencies
Category 2 focuses on addressing projected capacity constraints driven by future growth and development. The analysis was conducted using the 2035 Enhanced scenario, which incorporates flows from planned and approved development flows.

Category 2 projects will provide hydraulic capacity for approximately 13,848 LF of pipe must be upsized under PPWF. Figure 6.2 illustrates the locations, and proposed diameter increases for each of the deficient pipes. Table 6.2 lists all the pipe segments identified and the proposed size.

6.3 Category 3A: Existing Pipe Structural Deficiencies
Category 3A addresses the physical structural defects in the system identified through closed-circuit television (CCTV). Structural deterioration, such as cracking, deformation, joint separation, and root intrusion, can lead to failures within the system and affect the operations. The pipes within this 169
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 6-2 category were identified within the CCTV Survey Results Evaluation and Pipeline Replacement Priorities Area 2, Trunk Line, and All Areas by Sierra West as high-priority pipes to be replaced.

WBSD is currently performing ongoing sewer system maintenance assessments through cleaning and CCTV inspections. As of the date of this report, approximately three miles of pipe have been assessed.

Once WBSD field investigation is completed, the proposed improvements should be evaluated for inclusion in the annual improvement budget for aging infrastructure.

Category 3A projects will provide improved resilience for approximately 9,796 LF of pipe was identified as structurally deficient and prioritized for replacement. Figure 6.3 illustrates the location of the highpriority structural, same size replacement segments. Table 6.3 lists all the pipe segments identified and the proposed size.

However, approximately 5,166 LF of pipes overlap with either Category 1 or Category 2 for hydraulic capacity. Figure 6.4 illustrates the location of the pipes with both a high-priority structural deficiency and hydraulic capacity deficiency for improvements.

6.4 Category 3B: Remaining Pipe in the Sewer System
Category 3B addresses the remaining pipes within the collection system that have not been determined to either be capacity deficient or structurally deficient. Most of the existing collection system pipe segments are nearing or exceeding their anticipated service life, typically 50 to 75 years for vitrified clay pipes.

The total remaining length of pipe recommended for phased replacement from VCP to HDPE is approximately 73% of the existing system. Figure 6.5 illustrates the remaining system segments slated for replacement.

FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 7-1 7 Capital Improvement Program
Section 7 summarizes the Capital Improvement Program (CIP) projects, based on the categories discussed in Section 6 – Collection System Assessment. The CIP methodology was developed to establish a prioritized timeline for each project and provide an associated Conceptual Opinion of Probable Project Cost (OPPC).

7.1 Capital Improvement Program Development
Based on the classifications outlined in Section 6, a comprehensive evaluation of system improvements was conducted. All CIP project OPPC were developed at a planning level in 2025 dollars. The OPPCs include allowances for additional project components necessary for implementation, as shown below:
• Construction Contingency: 30%
• Design: 10%
• Environmental/Permitting: 10%
• Construction Management and Inspections: 15%
• District Administration: 5%
The cost factors listed above were applied uniformly across all categories to provide a consistent and comprehensive planning-level OPPC.

CIP projects were developed and grouped primarily with their improvement category. However, in several cases, the more than one category pipeline will be addressed by projects due to overlap or immediate proximity. Below is a summary of the project Groups

7.1.1 Category 1 Existing Conditions CIP Project Group
Category 1 CIP projects address existing capacity constraints and were divided into two separate project areas. Locations and project extents are illustrated in Figure 7.1. Taking advantage of project proximity, some additional Category 3A pipes improvements were also added into this CIP group.

The two projects, designated as CIP 1.1 and CIP 1.2, are both scheduled to initiate the design phase during the 2025–2026 fiscal year. CIP 1.1 is anticipated to begin construction in the 2026–2027 fiscal year. Due to the need for additional environmental permitting and coordination with PG&E, the design phase for CIP 1.2 is expected to span two fiscal years, from 2025 to 2027. Construction for CIP 1.2 is scheduled to commence in the 2027–2028 fiscal year and is projected to be completed in the 2028– 2029 fiscal year.

The total estimated cost for the Category 1 CIP projects is approximately $17.4 million. The project summary OPPC breakdown is presented in Table 7.1. These projects are funded by the existing customer base. The detailed breakdown of the OPPC is included in Appendix E. 171

7.1.2 Category 2: Developer Related CIP Project Group
Category 2 CIP projects address anticipated capacity deficiencies associated with future development and were divided into seven distinct project areas, as shown in Figure 7.2. Similar to the Category 1 CIP group, portions of Categories 2 and 3 deficient pipes overlap. The capacity expansion of Category 2 deficient pipes within this CIP group remains developer-related, as increasing their size would not be required by the existing customer base. Taking advantage of project proximity, small portions of both Category 1 and 3 deficient pipes were also added to this Category 2 CIP group. Approximately 93% of the Category 2 CIP projects are directly developer-related.

The specific impacts and any associated fees for each project will be evaluated on a case-by-case basis.

Developers may be responsible for preparing the design and performing the construction work under the supervision of the District. In certain instances, developers may be permitted to provide design and construction services as in-kind contributions, which may be credited toward their financial obligations to the District.

Due to the dependence on future development, the implementation schedule for Category 2 CIP projects should remain flexible and be reviewed regularly in coordination with EPASD. A sewer monitoring program is recommended as well to support project prioritization. If anticipated developments are delayed or not constructed, related structural improvements incorporated may require reclassification as higher-priority projects.

The total estimated cost for developer-related and adjacent deficient pipe CIP projects is approximately $52.8 million. The project summary OPPC breakdown is presented in Table 7.2. The detailed breakdown of the OPPC is included in Appendix E.

7.1.3 Category 3A: Existing Structural Deficiency CIP Project Group Category 3A CIP projects address structural defects identified through CCTV inspections and were divided into four project areas. The projects were divided to be approximately $2 million over the next five years. Project locations are shown in Figure 7.3.

The total estimated cost for remaining structural deficiency CIP projects not covered in the other groups is approximately $7.3 million. The project summary OPPC breakdown is presented in Table 7.3.

These projects are funded by the existing customer base. The detailed breakdown of the OPPC is included in Appendix E.

7.1.4 Category 3B: Aging Infrastructure CIP Project Group Category 3B encompasses the remaining sewer system assets not currently identified as hydraulically or structurally deficient but nearing the end of their expected service life. These pipes are recommended for phased replacement over a 25-year period to maintain system integrity and service reliability. The OPPC for the remaining aging infrastructure CIP projects not covered in the other groups will be approximately $4.3 million per year, with an overall total of $107 million. The cost is based on slip lining and replacement hybrid concept approach. The cost is not reflective of the complete trenching and replacement of the sewer system, which would require additional analysis. The project 172
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 7-3 summary OPPC is presented in Table 7.5. Fund sources evaluation is recommended to support aging infrastructure improvements, such as the California Clean Water State Revolving Funds (SRF) funded by the Environmental Protection Agency (EPA).

7.1.5 Capital Improvement Projects – All Categories
A consolidated summary of all proposed CIP projects is presented in Table 7.4, including brief descriptions, cost estimates, and recommended implementation priority. The combined geographic distribution of these projects is illustrated in Figure 7.4. Detailed project summary sheets are provided in Appendix E, which include the scope of work and estimated OPPC values.

An annual budget of $2 million per year is recommended for Category 3B projects to replace the existing aging infrastructure. The phasing and prioritization should be determined through the following methods:
• Yearly maintenance inspections,
• Flow monitoring, and
• Available funding.
173
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers. 8-1 8 Rate and Impact Fee Study
Section 7 describes the methodology and summarizes the analysis that was used to determine the impact fee for future customers.

As part of the ongoing development of the Master Plan and identification of new CIP projects, EPASD intends to update its impact fee to accurately reflect the costs associated with planned system improvements and infrastructure expansion. The estimated impact fee based on the necessary CIP for the Category 2 project is $7,800 per EDU with an annual escalation. The calculation for the impact fee is presented in Table 8.1.

This fee has been calculated based on the following cost components, with a comprehensive summary included in Appendix F:
• Developer’s share of existing capacity assurance: 25 percent of the costs are associated with existing capacity assurance improvements. These improvements are anticipated to provide capacity benefits for future growth. The developer-associated cost was determined through a flow-based analysis. It evaluated the projected increase in sewer system flow contributed by new development relative to total system demand.
• Developer’s Improvement: 100 percent of the costs related to capacity deficiencies that are directly attributable to new development demands.
• Buy-In Treatment Cost: A buy-in cost of $5 million per 1.0 million gallons per day (MGD) of treatment capacity, representing the proportional reimbursement by developers for the available capacity at the PAWRQCP.

1 Introduction
Freyer and Laureta, Inc. (F&L) has prepared this memorandum to document the development of a new sewer collection system model. The East Palo Alto Sanitary District’s (EPASD) wastewater collection system was developed by EPASD using Hydra 7 software by Pizer Incorporated (Hydra 7). The Hydra 7 hydraulic model was first used by EPASD in the 2015 Master Plan. The hydraulic model created a mathematical representation based on the physical properties and operational information of the system and was calibrated using field data. As the initial Hydra 7 model software is no longer supported, the model needed to be rebuilt with modern software. F&L was tasked to recreate the hydraulic model using a GIS-based hydraulic model platform, which was done using SewerGEMS within OpenFlows Sewers Advanced by Bentley Systems, Incorporated. This memorandum outlines the steps that were taken to recreate and validate the model.
2 Model Methodology
F&L used a structured workflow to develop the SewerGEMS model. The legacy Hydra7 software was inaccessible, so the approach began with a research phase. This involved compiling archived and limited GIS sewer maps, PDFs, and database output files. Thereafter a series of tasks were developed, often iterative, to produce a final working model.

The major tasks and sub-tasks identified became the basis of the model rebuilding approach and included:

1. Model Development
a. Gathering archived 2014 field, model, and mapping data used in the 2015 Master plan b. Re-building a complete and detailed sewer map in GIS c. Importing sewer model and field flow data

2. SewerGEMS model Calibration
a. Iteratively updating sewer properties through calibration b. Developing the Average Dry Weather Calibration buy analyzing HGL c. Therafter completing the Peak Wet Weather Calibration

3. Peformaing final quality checks on the SewerGEMS model results for final accuracy

4. Next steps: Model the 2025 and 2035 sewer conditions 3 Model Development
215
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers 2

3.1 Gather Archived Model and Mapping Data
The first step in developing the updated model was to gather all available datasets from EPASD to support the construction of the ArcGIS sewer map using existing EPASD shapefiles, Microsoft Access database files, and Excel spreadsheets associated with the Hydra7 model developed for the 2015 Master Plan. Once all data sources were assembled, the information was reviewed and organized to confirm the accuracy and completeness of the sewer system inputs required for GIS mapping.

3.2 Build ArcGIS Sewer Map
The next step in the modeling process was to construct an accurate and functional ArcGIS map of EPASD’s sewer system. The GIS map serves as the spatial foundation for the hydraulic model and must reflect reliable infrastructure attributes and connectivity. Archived GIS shapefiles were imported into ArcGIS and systematically compared to the Hydra7 model databases to verify the accuracy of system components, including manholes, pipes, and associated attributes.

To ensure data accuracy, key infrastructure attributes were reviewed across the archived GIS shape and model files.

These features included manhole IDs, rim and invert elevations, pipe lengths, diameters, friction factors, and connectivity. The Hydra7 model contained the most recent field-verified measurements and system-wide modeling results and was used as the primary reference for validating and correcting discrepancies in the spatial data.

The following assumptions were applied in developing the ArcGIS sewer map:

1. Hydraulic Attribute Consistency: The Hydra7 data was assumed to represent the most accurate and current values for manhole and pipe attributes, including rim and invert elevations, lengths, diameters, and Manning’s n values.

2. Pipe Material and Friction Factors: A single Manning’s roughness coefficient of n = 0.013 was applied throughout the system, consistent with vitrified clay pipe, the predominant material in EPASD’s network, and validated by the Civil Engineering Reference Manual.

3. Manhole Dimensions: All manholes were modeled as 48-inch diameter circular structures, in accordance with EPASD standard design specifications.

4. Invert Elevation Logic: Invert elevations were assumed to match the lowest connected pipe at each manhole.

Given EPASD’s relatively flat topography and supporting field observations, this assumption provides a reasonable basis for establishing flowlines. The horizontal datum used is the North American Datum of 1983 (NAD83, NSR 2007), and the vertical datum is the National Geodetic Vertical Datum of 1929 (NAVD 29).

5. Head Loss Representation: Minor losses at manholes were incorporated using industry-standard head loss coefficients for pipe bends. These values were based on the Standard Loss Method as documented in Bentley’s OpenFlows Water Infrastructure modeling software.

The GIS base map and associated attribute dataset formed the foundation for updating the hydraulic model and performing system capacity assessments.

3.3 SewerGEMS Model Development
Following the creation of the ArcGIS sewer map, the spatial data was imported into SewerGEMS within Bentley’s OpenFlows Sewer Advanced platform to initiate hydraulic model development. Upon import, all manhole and pipe 216
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers 3 segment attributes—including labels, elevations, and connectivity—were reviewed against the GIS map to ensure accurate data transfer.

During this verification process, several issues were identified and corrected prior to running any simulations:

1. Duplicate and Conflicting Identifiers: The imported GIS data contained several duplicate or conflicting manhole and pipe labels. The discrepancies were resolved by cross-referencing EPASD’s official system map from the 2015 Master Plan. All naming conventions were updated within the GIS data to maintain consistency with EPASD records.

2. Connectivity Errors: Several manholes and pipes were found to be improperly connected or entirely disconnected within the GIS data. The GIS data was corrected to ensure continuous hydraulic flow throughout the modeled network.

To validate basic model functionality, ADWF from the Hydra7 dataset were input into the SewerGEMS model and used to run a preliminary test simulation. The test simulation served as an initial calibration step and revealed inconsistencies that required updates to certain model parameters. The following adjustments and assumptions were made:

1. Head Loss Adjustments: The original Hydra7 model did not account for head loss at manholes. When industry-standard head loss coefficients (as described in Section 3.2) were applied, the resulting flow levels did not align with observed average dry weather field data. To reconcile this, all head loss values at manholes (nodes) were temporarily set to zero for the purposes of model calibration.

2. Ponding Area Assumptions: Manholes were assigned a ponding area property value of zero. The ponding area assumption setting enabled the model to track and report the volume of predicted Sanitary Sewer Overflows (SSOs) lost during simulations. The approach was developed iteratively during the calibration process.

The updates described above resulted the SewerGEMS model accurately represented EPASD’s sewer system and was properly configured for subsequent calibration and capacity analysis. 4 SewerGEMS Model Calibration
The SewerGEMS model calibration process focused on validating two critical parameters: (1) the hydraulic grade line (HGL) and (2) flow rates at model nodes. Calibration was conducted for two distinct flow scenarios: (1) Average Dry Weather Flow (ADWF) and (2) Peak Wet Weather Flow (PWWF). The methods used to validate input data for both scenarios is described in the follow sections.

4.1 Average Dry Weather Calibration
For ADWF conditions, flow inputs for all upstream manholes in the system were derived from the Hydra7 model Excel files. Figure 1 illustrates the locations of the upstream manholes, which were designated as flow injection points. The total ADWF injection flow was cross-checked and validated against the Hydra7 model database, which reports a total system flow of 1.53 million gallons per day (MGD).

SewerGEMS model results for ADWF were compared against Hydra7 model data and available field data for flow rates and maximum HGL at each manhole. Table 1 presents the comparison of flows and HGL values between the two models. The comparison showed good agreement, with a few outliers identified.

Civil Engineers · Surveyors · Construction Managers 4 The ADWF calibration step confirmed that the input parameters were accurately transferred to the SewerGEMS model and that base flow conditions were properly established. With ADWF successfully calibrated, the next step was to validate the model under peak wet weather conditions.

4.2 Peak Wet Weather Calibration
The calibration of the PWWF involved importing the injection flows from the Hydra7 model into SewerGEMS. The resulting predictions for surcharge and SSOs did not align with those from the Hydra7 model, likely due to insufficient information on how the Hydra7 model accounted for surcharged conditions and SSOs. The discovered discrepancy prompted an iterative process to investigate and resolve the differences in model results, leading to the following findings:

1. Flow Losses: Model simulations indicated flow losses within the system. To address this, a ponding property was added to capture and return the predicted SSOs, as outlined in Section 2.3. This property update was applied system-wide for both ADWF and PWWF scenarios.

2. Surcharge and SSOs: Hand-calculated hydraulic analyses showed that the Hydra7 model predicted surcharge and SSOs in locations where they were unlikely to occur. These predictions did not align with field observations or the EPASD’s operational experience. As a result, the SewerGEMS model was found to more accurately reflect existing conditions.

3. Flow Adjustments: Discrepancies were observed in the injection flow rates, with high flows in singlefamily housing areas and low flows in multi-family dwellings. To correct this, flow injections at selected upstream manholes were adjusted to better align with EPASD’s 2013 zoning data. Flow rates in singlefamily areas were reduced, while multi-family areas received increased flow injections. These adjustments maintained the total system flow of 5.78 MGD, as recorded in the Hydra7 database, and provided a more realistic loading scenario across the system. Table 2 summarizes the changes in injection flows and the affected manholes.
5 SewerGEMS Model Results
Following the calibration process described in the previous section, the SewerGEMS model results were compared to the original hydraulic data from the Hydra7 model from the 2015 Master Plan. The comparison between the Hydra 7 and SewerGems output was performed to assess the accuracy and reliability of the SewerGEMS model in representing the system’s performance under both ADWF and PWWF conditions. The sections below detail the methods used for this comparison and summarize the key findings from each scenario.

5.1 Average Dry Weather Results
For ADWF, the maximum HGL from SewerGEMS at each manhole was compared to the HGL from the original Hydra7 model. In most cases, the predicted HGLs from SewerGEMS differed by no more than 6 inches from those predicted by the Hydra7 model, as shown in Table 1.

Five manholes were identified as outliers, likely due to one of the following causes:

1. Locations near manholes with split flow directions or passive bypass piping, as shown in Figure 2. Manhole Outliers: E33, L10, M2, M3.
218
FREYER & LAURETA, INC. Civil Engineers · Surveyors · Construction Managers 5

2. Duplicate manhole identifications, as discussed in Section 2.2. The Hydra7 model presented multiple data points for these manholes, making it unclear which data should be used for comparison. Manhole Outlier: H29.

Figure 3 shows the manhole outliers, which exhibited HGL differences ranging from nine inches to 24 inches, with SewerGEMS predicting lower HGLs than the Hydra7 model. The discrepancies are likely due to differences in routing strategies between the two models. However, as these outliers had minimal impact on adjacent branches, the outliers were considered insignificant in terms of overall model accuracy.

The full model outputs for ADWF are included in Attachment 1.

5.2 Peak Wet Weather Results
As described in Section 3.2, the PWWF model results could not be fully validated using HGL comparisons due to inconsistencies in the model. To verify the PWWF results, the following methods were used:

1. Manhole flows were compared to ensure that the total system flow of 5.78 MGD matched the total flow in Hydra7.

2. Predicted SSO locations were validated within the model.

3. System segments known to be surcharged, based on historical data and field observations, were validated in the model, including previous bypass pumping plans and flow metering results.

Figure 4 presents a map of predicted SSOs and surcharged segments in SewerGEMS. The model outputs and hydraulics for PWWF are included in Attachment 2.
6 Conclusions and Next Steps
The SewerGEMS model recreation has been validated as an acceptable tool for analyzing flows within EPASD sewer system. Based on the calibration and validation efforts, the model is now ready for more detailed analysis and future planning. The next steps in the process include:

1. Updating the GIS map file to reflect the most current As-Built data for the 2025 sanitary sewer system.

2. Recalibrating the hydraulic model under the following scenarios:
a. 2025 Conditions: Incorporating flow injections from the latest developments based on AsBuilt data to identify potential system issues or deficiencies. b. 2035 Conditions: Adding flow injections from the East Palo Alto 2035 General Plan and Ravenswood Specific Planto identify necessary system upgrades to accommodate future growth.
c. 2035 Enhanced Conditions: Adding flow injections from the 2035 General Plan, Ravenswood Specific Plan, and approved planned developments to identify infrastructure needs for future development.

3. Updating EPASD’s Master Plan to incorporate the results of the updated calibration and system analysis.

The next steps described above will ensure the model remains accurate and relevant for both current and future sewer system management.
