ANTIOCH CITY COUNCIL -1- AUGUST 25, 2026

SPEAKER RULES
Welcome to a meeting of the Antioch City Council. Your attendance is appreciated. The State Ralph M. Brown Act guarantees the public's right to address the City Council, within the framework of Speaker Rules. Because agendas encompass many business items, Speaker Rules enable the meeting to be efficiently conducted and concluded at a reasonable hour.

The City Council can only take action on items that are listed on the agenda. If you wish to speak about an item not on the agenda , the "Public Comments" section of the agenda is for you.

Unagendized comments are provided until no later than 7:30 p.m. when the City Council moves on to agenda items. There is another opportunity for public comments at the end of the meeting for those persons unable to provide comment earlier on the agenda.

If you wish to speak, either during "public comments" or during an agenda item, fill out a Speaker Request form, located at the entrance of the Council Chambers or notify the clerk. If using the speaker form, please place the Speaker Request form in the tray near the City Clerk before the Council Meeting begins. This will enable us to call upon you to speak. Important: The Speaker Request form is retained as a Public Record, and as such, may be shared with others upon request in line with the California Public Records Act. On your Speaker Request form, please identify if the comment is for “Announcement of Community Events”, “Public Comment”, or a specific “Agenda Item”. No one may speak more than once on an agenda item or during "public comments." Speakers will be notified shortly before they are called to speak. When you are called to speak, please limit your comments to the time allotted (up to 3 minutes, at the discretion of the Mayor). Speakers attending remotely shall wait with their microphones muted until it is their time for comment. When it is a remote speaker’s turn for public comment, the speaker will be instructed to unmute their microphone by the City Clerk. Failure by the sp eaker to unmute their microphone in a timely fashion or if the City Council is unable to hear their speaker’s comment for any reason shall result in the speaker being passed over for that item.

Speakers addressing the Council shall not make personal, impertinent, unduly repetitive, slanderous or profane remarks to the Council, any member of the Council, City staff or the general public, nor utter loud, threatening, personal or abusive language, n or engage in any other conduct that disrupts, disturbs or otherwise unreasonably impedes the orderly conduct of the Council meeting. Any person who makes such remarks, who utters loud, threatening, personal or abusive language, who is unduly repetitious or engages in extended discussion of irrelevancies, or who engages in any disorderly conduct that disrupts, disturbs or otherwise unreasonably impedes the orderly conduct of any Council meeting shall, at the discretion of the presiding officer or a majority of the Council, be denied the right to speak and escorted from the chambers for the remainder of the meeting. In the event the person is attending the meeting remotely, the person may be muted or expelled from the remote meeting and shall not be allowed to participate again remotely during that meeting.

When a person breaches the rules outlined above, the presiding officer shall request that a person who is breaching the rules be orderly and silent. If, after receiving a warning from the presiding officer, a person persists in disturbing the meeting, the presiding officer shall order him or her to leave the Council meeting. If such person does not remove himself or herself, the presiding officer may order any law enforcement officer who is on duty at the meeting to remove that person from the Council Chambers. In the event the person is attending the meeting remotely, the person may be muted or expelled from the remote meeting.

The "Consent Calendar" is a group of items which are determined to be routine. These items are

ANTIOCH CITY COUNCIL -2- AUGUST 25, 2026

usually considered all at once and approved without further discussion. If you are opposed to action which is recommended for an item on the "Consent Calendar," please submit a Speaker Request form before the meeting, and place in the Speaker Card tray near the City Clerk. This will enable the item to be removed from the “Consent Calendar” and call on you to speak.

During Public Hearings, each side is entitled to one "main presenter" who may not speak for more than 10 minutes; all other speakers during public hearing items, are entitled to a maximum of 5 minutes.

These time limits may be modified depending on the number of speakers or number of items on the agenda at the Mayor’s discretion. Groups who are here regarding an item may identify themselves by raising their hands at the appropriate time to show support for one of their speakers. During certain types of hearings, the applicant is allowed to give their presentation first. After all testimony is received, the applicant has an opportunity for rebuttal.

After hearing from the public, the agenda item will be closed. Deliberations will then be limited to members of the City Council.

If the meeting appears to be going late, the City Council may decide to continue some items to a subsequent meeting. The City Council will try to make this determination around 10:45 p.m. It is the goal to stop discussing agenda items no later than 11:00 p.m.

SM-1 _ Agenda Item #

STAFF REPORT TO THE CITY COUNCIL

DATE: Special Meeting of August 25, 2026

TO: Honorable Mayor and Members of the City Council

SUBMITTED BY: Dawn Merchant, Finance Director
Ana Cortez, Acting City Manager AEC

SUBJECT: Fiscal Year 2027-28 General Fund Budget Development

RECOMMENDED ACTION
It is recommended that the City Council provide feedback and direction for fiscal year 2027-28 General Fund budget development.

FISCAL IMPACT
The fiscal impact of this budget is outlined in this report and attachments.

DISCUSSION
The fiscal year 2026-27 budget was adopted on June 23, 2026, after many months of deliberation and diligent review. However, even with the extensive work that was done, we still did not manage to completely close the 2026-27 spending gap, and the forecast provided in June 2026 for 2027-28 was daunting, at almost $15M. That figure has been further refined to incorporate:

1. 3% COLA recently approved for the APOA bargaining unit ($745,667 FY28 impact). Of note, labor negotiations are still ongoing with 4 other bargaining units.

2. Reduction of $1.2M in projected contribution to HomeKey+ project with City Council rejection of the grant.

3. Detrimental decreases to our sales tax budgets from the latest projections from our consultant. They are projecting the City’s fiscal year 2026-27 regular sales tax to decline $1,139,000, and Measure W to decline $538,000, carrying this decrease into fiscal year 2027-28. However, these projections are based only through the first quarter reporting of calendar year 2026 reporting and will be further evaluated after the next sales tax quarter. We are recommending to be cautiously optimistic for fiscal year 2026-27 at this juncture and project only a $500,000 decrease in regular sales tax and $200,000 in Measure W, carrying that corresponding reduction into 2027-28.

As a result of these items, the projected 2027-28 deficit spending has increased slightly to $15.2M. Chart A presents the 2026-27 adopted budget and 2026-27 current revised

As a result of the budget amendments, and decrease in projected sales tax revenue, deficit spending has increased $1,908,106 to a total of $6,475,985.

This is not sustainable. In order to have sufficient time to begin tackling what seems near impossible, Council requested we start the budget process for 2027-28 early in the fiscal year with a budget stripped to legally required services only for a thoughtful review and discussion of community and fiscal impacts and what to build back in from the bottom up.

Let it be clear, the budgets presented are not what departments are recommending.

The budgets are what departments feel is the minimum funding needed to provide services. Other than part-time help, all currently approved staffing shows as fully funded, or continued frozen from FY27, along with the addition of 12 Police Officers as stated by City Council during prior budget deliberations.

Departments were tasked with reviewing the 2027-28 budget figures provided during the 2026-27 budget process and determining the minimum level of services they needed to provide, with the understanding that for the initial presentation, full time staffing would reflect current authorized levels, with the exception of the addition of 12 Police Officers.

Departments were also directed to provide impact statements of reductions made.

Chart C presents the starting point (“baseline”) of this conversation about what each department interprets as their bare minimum. This will be a dynamic draft budget that may change as each departmental budget is reviewed, discussed and strategized. It is anticipated that we will designate a study session once a month dedicated to review specific departments. This evening, the focus will be on non-departmental, City Council, City Clerk, City Attorney, Human Resources, Finance, City Treasurer and Community and Economic Development departments.

Of note for the baseline budget in Chart C, department wide vehicle replacement set- aside funds of $1,813,564 and computer equipment replacement set-aside funds of $163,100, for a total of $1,976,664, have been removed as there is no legal mandate to have replacement funds set aside. This will mean that vehicle and equipment purchases for the General Fund will either have to utilize existing replacement funds that have been accumulated, “borrowing” balances from all General Fund vehicles if there is not enough for the specific vehicle being replaced, or for vehicles that do not have a sufficient balance, the City can choose to budget only for vehicles that are no longer functioning and is considered an emergency situation to replace. Consequently, vehicle lives will have to be extended for as long as safely viable. Without setting aside funds, once the City is in better financial condition, there would need to be a catch-up of funds in order to accumulate sufficient resources for replacement of vehicles when their service life has expired.

With this initial baseline preparation in collaboration with departments, the deficit is projected at $2,500,998, however, such drastic reductions will result in some functions and services being either eliminated or near ineffective. To re-iterate, the baseline presented is just a starting point for discussion, and this governing body may have different ideas as to what constitutes the baseline verses what the departments have presented.

As we go through each department’s budget (Attachment A), we are asking for Council feedback regarding what to potentially add back in, continue to exclude, and what additional information, if any, to bring back before deciding. Of note, since Recreation is not part of the discussion this evening, the reduction in Recreation Services Support in Chart C reflects eliminating all recreation services. This is not a department recommendation, but providing recreation services is not a City mandate. The remaining cost represents existing full-time staffing, which would need to be re-assigned to other duties throughout the City, maintaining insurance on the facilities and maintaining the water park and its pools so that they do not become hazardous and blighted. When the Recreation budget is brought for discussion, a comparison of eliminating services verses scaled back programs and services will be evaluated.

These decisions will not be final and may be adjusted as we move through this exercise over the next several months. An excel spreadsheet will be displayed on screen so that we can enter adjustments to the budget figures and see real-time results of the actions.

MEMORANDUM
TO: Dawn Merchant, Director of Finance
FROM: LaTonia Peoples-Stokes, Assistant City Clerk
DATE: August 13, 2026
SUBJECT: Impact of Proposed Elimination of City Clerk Contracted Services This memorandum outlines the operational, legal, compliance, public-access, and customer-service impacts that would result from eliminating six contracted services currently utilized by the Office of the City Clerk:
• NextRequest – Public Records Request Management
• Laserfiche – Electronic Records Storage and Records Management • NetFile – Campaign and Form 700 Electronic Filing
• American Legal Publishing – Antioch Municipal Code
• Total Recall Captioning – Closed Captioning for Public Meetings • Document Shredding / Shred-It – Secure Records Destruction • Minutes Clerk – Assistance with timely minutes production enabling faster turnaround.
• Records Management Automation – Records Retention and Destruction • Docusign – Electronic signature signing
• Agenda Management Software - Automates the creation, publishing, and archiving of meeting agendas and packets, reducing prep time from days to minutes.

While eliminating these contracts would produce direct budget savings, the services would not disappear. The underlying statutory, records-management, transparency, accessibility, and election-related responsibilities of the City would remain. As a result, elimination would largely transfer costs and responsibilities from contracted services to City Clerk staff and other City departments.

EXECUTIVE SUMMARY
The proposed reductions would have a significant operational impact on the Office of the City Clerk.

These services support core functions of the City Clerk's Office, including public records administration, records retention and retrieval, campaign and financial disclosure filings, maintenance of the Municipal Code, accessibility of public meetings, and secure destruction of confidential records.

The most significant concern is that eliminating these services without providing replacement systems, funding, or additional staffing would create a capacity gap.

Existing City Clerk personnel would be required to absorb work currently performed through specialized software and vendors.

The impacts would include:

1. Increased staff workload and manual processing.

2. Increased risk of delays in responding to public records requests.

3. Increased risk associated with records retention, retrieval, and disposition.

4. Reduced efficiency and public accessibility of campaign-finance and Form 700 filings.

5. Increased difficulty maintaining and publishing an accurate, current Municipal Code.

6. Increased accessibility risk for residents who are deaf or hard of hearing.

7. Increased risk associated with the destruction of confidential and sensitive records.

8. Reduced transparency and public confidence in City operations.

9. Potential need to redirect existing staff from other mandated City Clerk responsibilities.

10. Potential costs for replacement systems, temporary staffing, outside legal assistance, or other services that could offset a portion of the anticipated savings.

1. NEXTREQUEST – PUBLIC RECORDS REQUEST MANAGEMENT
Current budget amount: $25,000
NextRequest provides the City's public records request portal and workflow for receiving, tracking, communicating about, and responding to public records requests.

The California Public Records Act requires a local agency, upon receipt of a request for records, to determine within 10 days whether the request seeks disclosable public

records and to notify the requester of the determination. The law also provides for limited extensions under specified circumstances.

Impact of Elimination
Without NextRequest, the Office of the City Clerk would need to establish and maintain a manual or alternative system for:
• Receiving and logging public records requests;
• Assigning requests to departments;
• Tracking statutory response deadlines;
• Communicating with requesters;
• Collecting responsive records from multiple departments; • Reviewing and organizing responsive documents;
• Tracking exemptions and redactions;
• Providing responsive records electronically;
• Maintaining a history/audit trail of communications and actions; • Monitoring outstanding and overdue requests; and
• Reporting on public records activity.

The City could continue to receive requests by email, mail, telephone, or in person; however, the absence of a centralized request-management system would significantly increase the amount of manual administrative work required of City Clerk staff.

Other California cities using NextRequest describe the platform as the City's public- records portal and use it to track requests and provide records to requesters.

Operational Consequences
Elimination would likely result in:
➢ High staff impact. Staff would have to create and maintain spreadsheets, email folders, shared drives, calendars, or another tracking mechanism. ➢ Increased deadline risk. Without automated workflow and centralized tracking, there is a greater possibility that requests, extensions, follow-ups, or departmental assignments could be overlooked.
➢ Reduced transparency. Requesters would lose the convenience of a centralized portal for checking request status and accessing responsive documents.
➢ Increased litigation/risk exposure. Delays, incomplete searches, inconsistent documentation, or failure to preserve communications could increase the City's exposure to complaints, appeals, or litigation.

➢ Potential diversion of staff resources. Staff time currently devoted to other Clerk responsibilities would have to be redirected toward records-request administration.

2. LASERFICHE – ELECTRONIC RECORDS STORAGE AND RECORDS

MANAGEMENT
Current budget amount: $50,000
Laserfiche provides electronic document storage and records-management capabilities.

The City's prior budget materials identify Laserfiche as the system used for records scanning and cloud storage of electronic records.

Laserfiche's records-management functionality supports the lifecycle of records, including creation, retrieval, storage, retention, and disposition. It can also support retention schedules, record classification, security, disposition eligibility, and documentation of records-management actions.

Impact of Elimination
Eliminating Laserfiche would require the City to identify an alternative repository or return significant portions of records management to manual or decentralized processes.

Potential impacts include:
• Reduced ability to centrally locate electronic records; • Increased reliance on paper files and departmental network drives; • Increased staff time spent searching for records;
• Difficulty maintaining consistent retention schedules; • Increased risk of duplicate or inconsistent records;
• Increased difficulty identifying records eligible for destruction; • Increased risk of premature or unauthorized destruction; • Increased storage requirements;
• Increased difficulty responding to public records requests; and • Increased risk when records are needed for audits, litigation, investigations, or historical purposes.

Laserfiche's records-management system is specifically designed to help organizations establish retention schedules, manage records through their lifecycle, and document final disposition.

Secondary Impact
This reduction would also affect other City departments. The City Clerk would likely need to establish alternative procedures and provide additional oversight and training to departments responsible for maintaining their own electronic records.

A records-management system is particularly important because the absence of a centralized system does not eliminate the City's obligation to retain, locate, produce, and appropriately dispose of records.

Laserfiche represents one of the greatest long-term operational risks because records management affects virtually every City department and is foundational to public records compliance, institutional knowledge, and legal defensibility.

3. NETFILE – CAMPAIGN FINANCE AND FORM 700 ELECTRONIC FILING Current budget amount: $12,000
NetFile provides the City's electronic filing infrastructure for campaign and financial disclosure information.

The City's current NetFile portal provides a public-access system through which members of the public can research campaign contributions and expenditures, review campaign statements, and examine committee filing histories. The filer portal allows candidates and committees to electronically submit disclosure reports required by the City and California's Political Reform Act.

NetFile also supports electronic filing functions associated with Form 700/Statements of Economic Interests.

Impact of Elimination
Eliminating NetFile would require the City Clerk to establish an alternative method for:
• Receiving campaign disclosure filings;
• Receiving required financial disclosure filings;
• Maintaining filer accounts and records;
• Reviewing submissions;
• Providing public access to filings;
• Maintaining historical filing information;
• Assisting candidates, committees, and public officials; • Monitoring filing deadlines; and
• Producing information for public inspection.

Compliance and Election Impact

This reduction is particularly significant because the City Clerk is responsible for administering various disclosure and election-related functions.

Moving from electronic filing to a predominantly paper-based process could increase:
• Staff processing time;
• Data-entry requirements;
• Filing errors;
• Public-access delays;
• Records storage requirements;
• Difficulty conducting searches and generating reports; and • Staff workload during election cycles and filing deadlines.

The City's existing NetFile portal demonstrates that the system is currently used as both a filer portal and a public transparency portal.

The elimination of NetFile would not eliminate the City's disclosure obligations. It would shift the responsibility for receiving, processing, maintaining, and making available the information to City staff through another system or manual process.

4. AMERICAN LEGAL PUBLISHING – ANTIOCH MUNICIPAL CODE
Current budget amount: $15,000
American Legal Publishing currently provides codification and maintenance of the City's online Antioch Municipal Code.

The City's budget materials specifically describe this service as updating and maintaining the online Antioch Municipal Code.

American Legal's municipal code platform provides an organized online version of local ordinances and includes supplements reflecting newly adopted legislation. Municipal- code sites also carry a disclaimer that the municipality's official copy controls, making internal records and adopted ordinances particularly important.

Impact of Elimination
If the contract is eliminated, the City would need to assume responsibility for:
• Incorporating newly adopted ordinances;
• Maintaining the online version of the Municipal Code; • Updating tables and indexes;
• Identifying provisions affected by new legislation;

• Ensuring amendments are accurately incorporated;
• Maintaining historical versions;
• Providing public access to current ordinances; and
• Coordinating legal review of codification changes.

Operational Consequences
This would create a specialized workload requiring considerable attention to detail.

5. TOTAL RECALL CAPTIONING – PUBLIC MEETING ACCESSIBILITY Current budget amount: $30,000
Total Recall Captioning provides professional real-time captioning services. The vendor describes its services as real-time captioning intended to provide access to spoken information for individuals with hearing loss.

The City of Antioch has historically used Total Recall Captioning for closed captioning of City Council meetings. City financial records identify payments for "closed captioning" under the City Clerk budget.

Impact of Elimination
Eliminating the service would require the City to develop an alternative method of providing accessible communication during public meetings.

This is particularly important because Title II of the Americans with Disabilities Act requires state and local governments to provide effective communication to individuals with communication disabilities. The U.S. Department of Justice identifies real-time captioning as one of the auxiliary aids that may be appropriate for people who are deaf or hard of hearing.

The DOJ specifically identifies town and council meetings as situations in which effective communication may require a sign-language interpreter or real-time captioning, depending on the individual's needs.

California's Brown Act also requires agendas to be made available in appropriate alternative formats when requested by a person with a disability and requires information concerning how disability-related accommodations may be requested.

Operational Consequences
Elimination could result in:
• Reduced accessibility of live City Council meetings;

• Increased reliance on automated captioning;
• Potential accuracy issues with automated captions;
• Increased staff responsibility for arranging captioning on an as-needed basis; • Increased risk that an accommodation request cannot be fulfilled quickly; • Potential ADA compliance concerns; and
• Reduced participation by residents who are deaf or hard of hearing.

Importantly, eliminating this contract would not eliminate the City's obligation to provide effective communication when required. The City would need to establish an alternative process and potentially incur costs elsewhere.

6. DOCUMENT SHREDDING / SHRED-IT – SECURE RECORDS DESTRUCTION Current budget amount: $500
The City currently budgets a relatively small amount for document shredding services.

Despite the relatively low dollar value, eliminating this service could create a disproportionate records-security risk.

Impact of Elimination
The City Clerk and other departments routinely handle documents containing sensitive or confidential information, including information that may contain:
• Personal identifying information;
• Personnel information;
• Confidential legal information;
• Financial information;
• Election-related information;
• Protected or exempt public records; and
• Records that have reached the end of their authorized retention period.

Without a secure destruction vendor, departments would need an alternative process for destroying eligible confidential records.

Possible alternatives could include:
• Purchasing additional shredding equipment;
• Assigning employees to shred documents;
• Establishing centralized shredding procedures;
• Transporting materials to another secure destruction facility; or

• Contracting with another vendor.

Operational Consequences
Employee shredding would create additional workload and would not necessarily provide the same chain-of-custody or documented destruction process available through a professional secure-destruction service.

The savings associated with eliminating the service are relatively small compared with the potential consequences of inappropriate disposal of confidential records.

Although the direct financial savings are minimal, the risk associated with improper disposal of confidential information warrants maintaining a secure destruction process.

7. CONTRACTED MINUTES CLERK
Current budget amount: $50,000
Current Function has been eliminated due to the retirement of the Clerk.

The contracted Minutes Clerk provides specialized support for preparing official meeting minutes, reducing the amount of time City Clerk staff must spend listening to meetings, preparing draft minutes, researching meeting actions, and completing post-meeting documentation.

Impact if Eliminated
If the contract is eliminated, the work would need to be absorbed by existing City Clerk staff.

The additional responsibilities could include:
• Reviewing meeting recordings.
• Preparing draft minutes.
• Verifying motions and votes.
• Confirming speaker names and public testimony.
• Formatting minutes.
• Preparing minutes for approval.
• Making corrections.
• Maintaining the official minutes record.
• Posting approved minutes.

Operational Impact

This would create a direct workload increase following every Council or legislative-body meeting.

The impact would be particularly significant during:
• Budget season.
• Election periods.
• Special meetings.
• Multiple-meeting weeks.
• Meetings with lengthy public testimony.
• Meetings involving complex ordinances, resolutions, or motions.

The City Clerk's Office would have less capacity to perform other statutory and customer-service responsibilities during the period immediately following meetings.

Accordingly, shifting minutes production entirely to existing staff creates a capacity and continuity risk.

8. DOCUSIGN – ELECTRONIC SIGNATURE SERVICES
Current budget amount: $2,500
DocuSign provides electronic signature and routing capabilities for City agreements, contracts, forms, approvals, and other documents requiring signatures.

DocuSign specifically markets its electronic-signature and agreement-management services to government agencies, including automated signing, routing, filing, security, and compliance capabilities. DDocuSign
Impact if Eliminated
The City would need to return to paper signatures or establish another electronic- signature solution.

Potential consequences include:
• Printing documents.
• Physical routing between departments.
• Mailing or hand-delivering documents.
• Scanning signed documents.
• Manual follow-up with signers.
• Increased turnaround times.

• Increased paper and storage costs.
• Increased staff time.
• Difficulty obtaining signatures from remote or multiple parties.

Operational Impact
The primary effect would be a reduction in processing efficiency.

Although individual transactions may only require a few additional minutes or hours, the cumulative effect across hundreds or thousands of documents could be substantial.

The City could operate without DocuSign if an acceptable alternative is available.

However, eliminating electronic signatures without replacement would significantly increase administrative processing time.

9. CIVIC CLERK AGENDA MANAGEMENT SOFTWARE
Current budget amount: $13,233.00
CivicClerk, now marketed as CivicPlus Agenda and Meeting Management, provides agenda creation, agenda packet preparation, meeting management, board/public portals, and related meeting workflows. CCivicPlus
The platform supports the creation and management of agenda items, reports, attachments, meeting materials, and public-facing agendas. CCivic Clerk+1 Impact if Eliminated
The City Clerk's Office would need to manually manage:
• Agenda item submissions.
• Staff reports.
• Attachments.
• Agenda sequencing.
• Agenda packets.
• Council distribution.
• Public posting.
• Corrections and revisions.
• Meeting materials.
• Historical agendas.
• Public access to meeting information.

California's Brown Act requires regular meeting agendas to be posted at least 72 hours before a meeting. Current law also establishes specific requirements for online agendas, including accessibility, searchability, machine readability, and public access.

Operational Impact
Eliminating the system would substantially increase the administrative burden on the City Clerk's Office and increase the number of manual steps required to produce each agenda.

There would also be greater risk of:
• Posting errors.
• Version-control problems.
• Missing attachments.
• Delayed agenda publication.
• Incorrect agenda sequencing.
• Increased staff overtime.
• Reduced public convenience.
• Increased difficulty maintaining historical meeting information.

The City's obligation to conduct and publicly notice meetings does not disappear if the software is eliminated. The technology simply becomes the responsibility of staff to replace.

11. RECORDS MANAGEMENT AUTOMATION
Current budget amount – $150,000
The proposed $150,000 Records Management Automation initiative would provide automation capabilities for the City's records-management program. The purpose of records-management automation is to reduce the amount of manual staff intervention required to classify, organize, retain, retrieve, and ultimately dispose of records in accordance with established retention requirements.

This function is particularly important when considered together with the proposed reduction of Laserfiche and Shred-it services. Records management is not limited to storing documents. The City must also establish appropriate retention periods, identify records eligible for disposition, preserve records that must be retained, and ensure that records are not inadvertently destroyed.

Impact if Eliminated
If the $150,000 records-management automation funding is eliminated, the City would continue to have the underlying records-management workload but would have fewer automated tools to perform that work.

The City Clerk's Office and other departments would likely need to rely more heavily on manual processes to:
• Classify and organize electronic records.
• Apply and monitor records-retention schedules.
• Identify records approaching their authorized disposition date. • Review records before destruction.
• Document records disposition.
• Locate records for public records requests.
• Identify duplicate or obsolete records.
• Maintain consistent records-management practices across departments. • Monitor records stored in multiple systems and locations. • Respond to audits, litigation holds, public records requests, and other records- related inquiries.

Operational Impact
The primary impact would be a significant increase in staff time devoted to records- management activities.

Without automation, records management becomes more dependent upon individual employees remembering retention requirements and following manual procedures. This creates greater variation among departments and increases the possibility that records will be:
• Retained longer than necessary;
• Not retained for the required period;
• Misclassified;
• Difficult to locate;
• Duplicated across multiple systems; or
• Destroyed without sufficient documentation or review.

The impact would be amplified if Laserfiche is also eliminated because the City would lose both the underlying electronic records-management platform and the opportunity to automate records-management processes.

The proposed $150,000 reduction should therefore not be evaluated independently from the proposed cuts to Laserfiche and Shred-it.

Those three functions address different portions of the records life cycle:

Records Management Automation → Laserfiche → Secure Destruction Automation helps identify and manage records according to established requirements; the records-management system provides a controlled environment for storing and retrieving records; and secure destruction provides a controlled means of disposing of records when legally authorized.

Eliminating all three would substantially increase the City's reliance on manual processes and staff knowledge.

The risk associated with eliminating records-management automation is primarily operational and records-compliance related.

The City would still have to comply with applicable records-retention and records- disposition requirements. California law establishes specific requirements governing the destruction of municipal records, including special provisions concerning legislative minutes, ordinances, resolutions, and other records.

Fiscal Consideration
The proposed savings of $150,000 should be evaluated against the staff resources required to perform the same functions manually.

The actual cost of eliminating automation may therefore include:

1. Additional City Clerk staff time;

2. Additional departmental staff time;

3. Overtime or temporary staffing;

4. Manual records review and classification;

5. Additional records-storage requirements;

6. Increased time responding to public records requests;

7. Increased difficulty identifying records eligible for disposition;

8. Potential future costs associated with records cleanup and migration; and

9. Increased compliance and litigation risk associated with inconsistent records- management practices.

At a minimum, the City should establish a documented interim process identifying:
• Applicable retention schedules;
• Departmental records-management responsibilities;
• Procedures for identifying records eligible for disposition; • Required approvals before destruction;
• Documentation of records destruction;
• Procedures for litigation holds and other preservation requirements; • Responsibility for responding to records-management questions; and • A future implementation plan for records-management automation.

Conclusion: Eliminating the $150,000 Records Management Automation initiative would produce an immediate budget reduction, but it would also leave the City with a largely manual records-management process at a time when the volume and complexity of electronic records continue to increase. The impact would be particularly significant if Laserfiche and Shred-it are also eliminated, because the City would lose multiple layers of its existing records-management infrastructure simultaneously.

CUMULATIVE IMPACT ON THE OFFICE OF THE CITY CLERK
The proposed reductions should not be evaluated solely as individual contracts.

Collectively, they form an interconnected infrastructure supporting the City's transparency, records management, elections, public meetings, accessibility, and information governance.

For example:

Public Records:

NextRequest manages requests → Laserfiche helps locate records → Shredding supports lawful disposition.

Public Meetings:

Total Recall supports accessible participation → City Clerk maintains meeting records and public information.

Elections and Ethics:

NetFile provides electronic filing and public disclosure → City Clerk administers filing requirements and assists filers.

Municipal Legislation:

American Legal Publishing provides public access to the codified Municipal Code → City Clerk supports legislative records and ordinance administration.

Eliminating multiple services simultaneously would therefore have a cumulative effect greater than the individual dollar amounts suggest.

STAFFING IMPACT
The most significant hidden cost associated with these reductions would be the transfer of vendor responsibilities to City employees.

If all contracts were eliminated, the Office of the City Clerk would likely need to assume additional responsibilities involving:
• Manual public-records tracking;
• Records scanning and indexing;
• Records retrieval;
• Retention and disposition tracking;
• Campaign and financial disclosure processing;
• Municipal Code updates;
• Captioning coordination;
• Secure records destruction;
• Increased customer service;
• Additional deadline monitoring;
• Increased document preparation; and
• Increased coordination with other City departments.

Unless staffing levels or priorities are adjusted accordingly, these responsibilities would compete with the Clerk's existing statutory and administrative responsibilities and place significant staffing burden on the Office of the City Clerk and its undermanned staff.

Consequently, the budget savings should be evaluated against the staff hours required to recreate these services internally with an already understaffed department.

RECOMMENDATION
The Office of the City Clerk recognizes the City's current fiscal constraints and supports the City's efforts to identify sustainable reductions.

However, the potential elimination of these services should be considered service reductions rather than simple contractual savings.

If the City proceeds with eliminating any of these contracts, the corresponding staff workload, compliance responsibilities, and operational risks should be explicitly identified and assigned before termination.

The Office of the City Clerk recommends that, if reductions are necessary, the City consider the following approach:

1. Prioritize preservation of services with statutory or civil-rights implications, particularly public records compliance, accessibility, elections/disclosures, and records management.

2. Evaluate lower-cost alternatives before complete elimination, including shared services, renegotiated contracts, reduced service levels, or competitive procurement.

3. Calculate the internal staff cost required to replace each vendor's services before counting the full contract amount as a net budget savings.

4. Establish replacement procedures before terminating any system or service.

5. Avoid eliminating multiple interconnected records-management services simultaneously, as this could compound operational and compliance risks.

6. Require a transition plan for any system being eliminated, including preservation and migration of historical records and data.

CONCLUSION
The proposed elimination of these services currently provided through these contracts support essential City functions. Eliminating them would shift substantial responsibilities to City staff and could increase the City's exposure to operational delays, records- management problems, public-access concerns, accessibility issues, and compliance risks.

The Office of the City Clerk therefore recommends that any proposed reduction be evaluated based on total cost, including staff time and risk, rather than contract expenditure alone.

The objective should be to achieve necessary budget reductions while maintaining the City's ability to meet its obligations for public access, transparency, records preservation, elections and disclosure, accessibility, and lawful records disposition.

Market Update
▸ U.S. growth remains resilient as AI-driven investment offsets a moderating consumer ▹ Headline inflation may be at or near its peak as the energy shock fades, though flare-ups in the Middle East conflict and potential delayed passthroughs to core inflation remain key risks ▹ The labor market is in balance, though real wage growth remains modest ▹ AI investment continues to drive growth while fueling inflation in tech-related categories ▸ The Federal Reserve (Fed) left policy rates unchanged at 3.50-3.75% ▹ New Fed Chair Kevin Warsh stressed restoring price stability ▹ Forward guidance was removed to refocus markets on economic fundamentals and incoming data rather than the Fed's policy response
▹ Nine participants projected a 2026 rate hike though Warsh did not submit projections ▸ Treasury yields moved higher on a more hawkish Fed
▹ Given current pricing of Fed rate hikes, we continue to find value in the front end ▹ Longer-term rates face two-sided risks from inflation and growth dynamics ▹ Credit spreads remain tight as resilient growth, stable labor conditions, and strong demand outweigh valuation concerns

Accrued Interest: Interest that is due on a bond or other fixed income security since the last interest payment was made.

Agencies: Federal agency securities and/or Government-sponsored enterprises.

Amortized Cost: The original cost of the principal of the security is adjusted for the amount of the periodic reduction of any discount or premium from the purchase date until the date of the report. Discount or premium with respect to short-term securities (those with less than one year to maturity at time of issuance) is amortized on a straight line basis. Such discount or premium with respect to longer-term securities is amortized using the constant yield basis.

Asset-Backed Security: A financial instrument collateralized by an underlying pool of assets – usually ones that generate a cash flow from debt, such as loans, leases, credit card balances, and receivables.

Bankers’ Acceptance: A draft or bill or exchange accepted by a bank or trust company. The accepting institution guarantees payment of the bill as well as the insurer.

Commercial Paper: An unsecured obligation issued by a corporation or bank to finance its short-term credit needs, such as accounts receivable and inventory.

Contribution to Total Return: The weight of each individual security multiplied by its return, then summed for each sector to determine how much each sector added or subtracted from the overall portfolio performance.

Effective Duration: A measure of the sensitivity of a security’s price to a change in interest rates, stated in years.

Effective Yield: The total yield an investor receives in relation to the nominal yield or coupon of a bond. Effective yield takes into account the power of compounding on investment returns, while nominal yield does not.

FDIC: Federal Deposit Insurance Corporation. A federal agency that insures bank deposits to a specified amount.

Interest Rate: Interest per year divided by principal amount and expressed as a percentage.

Market Value: The value that would be received or paid for an investment in an orderly transaction between market participants at the measurement date.

Maturity: The date upon which the principal or stated value of an investment becomes due and payable.

Negotiable Certificates of Deposit: A CD with a very large denomination, usually $1 million or more, that can be traded in secondary markets.

Par Value: The nominal dollar face amount of a security.

Pass-through Security: A security representing pooled debt obligations that passes income from debtors to its shareholders. The most common type is the mortgage-backed security.

Repurchase Agreements: A holder of securities sells these securities to an investor with an agreement to repurchase them at a fixed price on a fixed date.

Supranational: A multinational union or association in which member countries cede authority and sovereignty on at least some internal matters to the group, whose decisions are binding on its members.

Trade Date: The date on which the transaction occurred; however, the final consummation of the security transaction and payment has not yet taken place.

Unsettled Trade: A trade which has been executed; however, the final consummation of the security transaction and payment has not yet taken place.

U.S. Treasury: The department of the U.S. government that issues Treasury securities.

Yield: The rate of return based on the current market value, the annual interest receipts, maturity value, and the time period remaining until maturity, stated as a percentage on an annualized basis.

It is recommended that the Cit y Council adopt a resolution aut horizing the sole source purchase of thirty (30) Motorola A PX N70 handheld two-wa y emergency radios, including accessories and five years of subscriber and device management services, from Motorola Solutions in an amount not to exceed $300,717.21.

FISCAL IMPACT
The total cost of this purchase is $300,717. 21, including estimated sales tax. This amount is fully funded through existing appropriations in the FY 26/27 Police Department General Fund budget. No additi onal General Fund appropriation is required.

DISCUSSION
The Antioch Police Department is continuing the phased replacement of aging handheld radios that have exceeded their manufac turer-supported service life and no longer provide the coverage, connectivity, and management capabilities needed for reliable emergency communications. In August 2025, the City Council aut horized the purchase of forty-four (44) Motorola APX Next radios as the sec ond phase of this replacement plan. The Department now reques ts approval to purchase an additional thirty (30) Motorola APX N70 radios as the next phase of the same multi-year effort.

The quoted package includes the radios a nd required accessories, including batteries, remote speaker microphones, chargers, antennas, and radio holsters. It also includes five years of SmartConnect, SmartLocate, SmartMapping, SmartMessaging, and Device Management Services. These services suppor t LTE connectivity, location and mapping capabilities, radio management, software main tenance, technical support, and repair coverage, helping keep the fleet current and operational throughout the service term.

Antioch City Council Report
August 25, 2026 Agenda Item# G 2

The newer Motorola APX radios purchas ed during the prior phase have already demonstrated their value during critical incidents and major emergencies:

 During the Somersville Fire on July 16, 2025, which burned 350 acres adjacent to the Silverado neighbor hood and prompted evacuation warnings, Officers deployed to the evacuation zone were able to coordinate seamlessly using the newer APX radios. Despite challenging terrain and the high volume of radio traffic, communications remained uninterrupted and reliable.

 On June 30, 2025, Oficers responded to a ma jor critical inciden t that required real-time coordination between patrol uni ts, dispatch, and field supervisors.

Officers equipped with the newer APX radios were able to maintain reliable communication throughout the incident.

This phased replacement also continues to address long-standing communications gaps identified in previous City Council discu ssions and in the California Department of Justice report concerning the December 2021 officer-involved shooting in Southwest Antioch (Attachment C). The APX platform provides several operational advantages:

 Improved communications in areas of the City where terrain can limit traditional radio-system coverage, including portions of southwest Antioch;

 Improved communications insi de critical infrastructure and large buildings, including medical facilities where structur al interference can affect traditional radio coverage; and

 Expanded connectivity through Motorola SmartConnect and LTE service, allowing supported radios to maintain communications when users move outside normal land-mobile-radio coverage or into areas where LTE provides a stronger path to the radio system.

Continuing with the Motorola APX platform also standardizes t he Department radio fleet. Officers and Dispatchers are alread y familiar with the equipment, controls, programming, and operating procedures. A common platform simplifies training, programming, encryption management, acce ssories, maintenance, and technical support while preserving interoperability wit h the East Bay Regional Communications System Authority (EBRCSA) network used by the Department.

SOLE SOURCE JUSTIFICATION
Motorola Solutions is the manufacturer an d sole source for the proprietary APX N70 radios and the associated Motorola subs criber and device management services included in this purchase. The Department is already standardized on the Motorola APX platform and relies on Motoro la programming, encryption, SmartConnect services, and EBRCSA-compatible configurat ions. Purchasing a different platform for this phase would require separate equipment, progra mming, training, accessories, support processes, and system integrat ion. Staff therefore recomm ends continuing the sole source procurement with Motorola Solutions, consistent with the City Council authorized Antioch City Council Report
August 25, 2026 Agenda Item# G 3

purchase made in August 2025 and applicable City purchasing policies.

APX N70 PORTABLE RADIO SOLUTION DESCRIPTION

OVERIVIEW

The APX N70 offers affordable, next generation communications for without compromising P25 interoperability or voice and data quality. It offers a durable design with “pick-up-and- go” functionality, optimizing ease-of-use and focused communications in almost all environments.

DURABLE AND EASY TO USE

The APX N70 enhances operations with a full color transflective glass display with touch technology for easy operation with gloves on. The touchscreen includes a high velocity user interface with large touch targets, shallow menu hierarchy, home screen information at a glance, and access to integrated apps. Additionally, the N70 offers extended battery life, a shorter antenna, and Bluetooth compatibility with audio accessories, promoting efficient communications between first responders.

ESSENTIAL AND SECURE P25 COMMUNICATIONS

The APX N70 is certified compliant with P25 standards and supports digital and analog trunking, FDMA and TDMA, and Integrated Voice and Data. P25 communications over the N70 are safe and secure–it offers software and hardware encryption, single- and multi key encryption, and P25 Authentication, protecting communications during daily operations.

Reliable Connectivity

Using the APX N70 lets first responders stay connected across disparate networks. It can be equipped with LTE, Wi-Fi ®, Bluetooth®, and GPS features, bringing future-ready applications, services, and best-in-class connectivity to everyday users. APX N70 radios support 7/800 MHz frequency bands across radio systems with minimal intervention by the radio user.

Managing and Provisioning Devices

APN N70 provides users greater awareness and faster radio management through Customer Programming Software (“CPS”), Radio Management (“RM”), or the Radio Central programming. These tools transform accurate data into smarter action by enabling dispatchers and network managers to keep radios in the field, make informed operational decisions, and, above all, protect first responders' focus and safety.

Customer Programming Service

CPS is a proprietary, Windows-based application used to configure APX subscriber radios in offline situations. The CPS application offers drag-and-drop, clone-wizard, and basic import/export functions that allow for the addition of new software and feature enhancements. APX N radios can be programmed one-at-a-time on a local PC, via secure USB port

connection, with TLS-PSK based encryption. Once loaded, subscriber radios are read, and edited, and copdeplugs and templates can be saved and duplicated to program other fleet radios.

Radio Management

Batch Programming is available through the RM software for simultaneous programming and upgrading throughout the radio fleet. With Batch Programming, up to 16 radios can be programmed at once over a Wi-Fi connection. This reduces programming time and ensures that the radio fleet is always up-to-date and ready-to-use in the field.

Device Management Services

Device Management Services (“DMS”) packages provide programming, management, and maintenance services to maximize the effectiveness of this APX N70 solution, while reducing maintenance risk, workload, and total cost of ownership. DMS tackles a range of customer needs, whether the solution is self-maintained or managed by Motorola Solutions.

Using Motorola Solutions’ cloud-based Radio Central Programming, APX N70 supports faster provisioning and deployment to get devices in the hands of first responders and out into the field. Parameters such as talk groups, interface options, and security keys can be programmed remotely within minutes. The DMS package provides access to batch programming with Radio Central Programming or one-at-a-time basic programming with Customer Programming Service, described below.

Radio Central

Radio Central Programming streamlines the APX N70 out-of-the-box experience with a few simple steps. Users will power on the device and view a boot-up animation. Status bar icons on the front display indicate when a connection is made and an update download is initiated. If the APN N70 device is being started for the first time, a “peek-in” device management notification will indicate that the default configuration is detected. When the update download is complete, the device reboots and installs the update. When the install is complete, the device goes back to the full home screen and notifies the user that the update is complete. From power on to provisioning, the process takes less than a minute. For Encryption and Authentication users, a KVL needs to be connected to the radio to use those services.

APX N70 also features Touchless Key Provisioning (“TKP”), leveraging Radio Central and Key Management Facility to add encryption keys remotely. This streamlined, one-time process reduces the time and effort spent enabling encryption. TKP delivers the initial encryption keys to APN N70 radios. Users can provision encryption on one radio or on batches of radios, further speeding up the encryption process for radio fleets.

The figure below illustrates APX N70’s faster provisioning process.

INTRODUCTION
On September 30, 2021, the Governor of the State of California approved Assembly Bill 481(codified as Chapter 12.8 of the California Government Code) requiring law enforcement agencies to have a military equipment use policy approved by the City Council prior to requesting, seeking funding, acquiring or using items that it defined as military equipment.

Assembly Bill 481 allows the governing body to approve the policy within its jurisdiction only if it determines that the military equipment meets specified standards.

On May 24, 2022, the Antioch City Council approved Ordinance 2213-C-S, approving Antioch Police Department Policy #706: Military Equipment Use Policy. On August 26, 2025, the Antioch City Council accepted the APD Military Equipment Report for 2024 and approved the continued use of that equipment. As required by Assembly Bill 481 and the Ordinance, annually, the Antioch Police Department must prepare a report on the use of each type of military equipment approved in the Policy over the last year. Subsequently, the City Council must then review the Ordinance, Policy and Annual Report, and determine whether the Department’s use of the defined military equipment in the past year complied with the Policy, and whether to continue the Ordinance and Policy, take action (by ordinance) to modify the Policy or repeal the Ordinance.

As the Policy outlines, the Antioch Police Department retains and employs limited equipment that falls under this legislation and subsequent law to safeguard its community. Antioch Police Department officers, certified instructional staff, and specialized units receive training throughout the year on the use of this equipment approved under the Policy.

This annual report outlines the Antioch Police Department’s military equipment inventory and usage and community complaints over the use of military equipment from January 1, 2025, through December 31, 2025. It also outlines the proposed purchase of new and/or replacement equipment during 2026.

Projected Equipment Acquisitions for 2026:

Pursuant to the procurement plan approved by the City Council on March 25, 2025, the Antioch Police Department (APD) intends to acquire two armored vehicles during the 2026 fiscal year.

This acquisition includes one BATT-X Armored Rescue Vehicle (ARV), which will serve as a modern replacement for the department’s aging Navistar MaxxPro M1224 (MRAP).

Additionally, the department will procure one armored Ford F-350 dedicated specifically to SWAT operations to enhance tactical response and officer safety during high-risk incidents

The Antioch Police Department also seeks to acquire the following items below, with City Council approval in 2026:

To modernize specialized firearm capabilities, the department will purchase five B&T APC9SD- LE-KIT SBR 9mm platforms to replace the aging, non-functional H&K UMP in our inventory.

Furthermore, to enhance de-escalation and less-lethal options for both Patrol and SWAT operations, the department intends to procure ten Penn Arms CTS L140-4 40mm single- launchers and two Penn Arms L640-3 multi-launchers.

Any additional purchase of new equipment in 2026 will include adhering to procedures outlined in our department policy and remaining consistent with the Military Equipment inventory list, policy, and department budget, previously approved by the City Council.

Conclusion:

There are some cases when military equipment is used or displayed that may cause concerns or raise questions from community members. In those instances, there is a process where community members can ask questions, express concerns, and make a complaint about the equipment’s use. These questions, concerns, and complaints can be directed to the police department through the complaint process on the police department’s website (https://www.antiochca.gov/comment-forms/police-comments-complaints- recommendations/) or directly to the Chief of Police at [email protected].

This Annual Military Equipment Report reaffirms the Antioch Police Department’s commitment to providing transparency and information to our community and elected officials, in compliance with California Assembly Bill 481.

STAFF REPORT TO THE CITY COUNCIL

DATE: Regular Meeting of August 25, 2026

TO: Honorable Mayor and Members of the City Council

SUBMITTED BY: Marcus Woodland, Water Treatment Plant Superintendent

APPROVED BY: Scott Buenting, Public Works Director/City Engineer

SUBJECT: Resolution Accepting and Adopting the 2025 Urban Water Management Plan and Water Shortage Contingency Plan; and Submitting the Plan to the Department of Water Resources P.W. 340-17

RECOMMENDED ACTION
It is recommended that the City Council adopt a resolution:

1. Approving the 2025 Urban Water Management Plan and the Water Shortage Contingency Plan; and

2. Authorizing City staff to submit the 2025 Urban Water Management Plan and Water Shortage Contingency Plan to the Department of Water Resources incorporating all appropriate comments at the close of the Public Hearing.

FISCAL IMPACT
The Capital Improvement Budget includes adequate funding for the development of the Urban Water Management Plan from the Water Enterprise Fund. Compliance with the current provisions of the Urban Water Management Plan Act is expected to result in no fiscal impact to the City’s General Fund.

DISCUSSION
The Urban Water Management Plan (“ UWMP”) Act requires all urban water suppliers serving municipal water to 3,000 customers, or supplying more than 3,000 acre- feet annually, to adopt and submit a n UWMP every five years to the Department of Water Resources (“DWR”). The City of Antioch provided 5,311 million gallons (16,298 acre-feet) of potable water for municipal purposes to 34,739 connections in 2025 and thus is required to comply with the requirements of the UWMP Act and prepare an UWMP.

The 2025 UWMP includes a description of the City’s service area, presents historical and projected water use, describes baselines and targets for per capita water use, describes system water supplies, addresses water supply reliability, describes the City’s water

Antioch City Council Report
August 25, 2026, Agenda Item #7 2
shortage contingency plan (“WSCP”), and describes demand management measures. The purpose of the UWMP is to encourage local water agencies and wholesalers to plan ahead with respect to meeting future water supplies and demands and to report on the City’s compliance with the Water Conservation Act of 2009 (Senate Bill X7-7) goal of achieving a 20 percent statewide reduction in urban per capita water use by the year 2020. A Public Hearing is required prior to adopting the 2025 UWMP and WSCP.

The 2025 UWMP incorporates standardized forms and tables as required by DWR.

The current update includes updated requirements compared to the previous UWMP guidance. These updated requirements are listed below:
• Changes in Water Code
• Suppliers with Multiple Public Water Systems
• DWR Submittal Tables
• Water Loss Standard Reporting
• Direct Potable Reuse
• Lower-Income Housing
• Reporting Groundwater Recharge and Other Water Storage

On March 23, 2026, t he City entered into an agreement with Black Water Consulting Engineers, Inc. to prepare the City of Antioch’s 2025 Urban Water Management Plan.

Submission of the adopted UWMP will fulfill compliance with the Urban Water Management Planning Act and support the City’s eligibility for applicable State water management grants and loans.

In accordance with California Water Code Section 10621(b), the City notified Contra Costa County and other stakeholders (including Contra Costa Water District) that the City was preparing the 2025 UWMP more than 60 days prior to the date of Public Hearing. The Draft 2025 UWMP was made available to the public and interested parties for review and comment. A notice of public hearing was published in the local newspaper and posted at City facilities in accordance with Section 6066 of the Government Code.

Within 30 days following adoption, the adopted 2025 UWMP will be submitted to DWR and the California State Library. Copies of the 202 5 UWMP will be provided to: Contra Costa County and Contra Costa Water District and will be made available for public review on the City’s website at https://www.antiochca.gov/.

WHEREAS, the 2025 UWMP includes a description of the City’s service area, presents historical and projected water use, describes baselines and targets for per capita water use, describes system water supplies, addresses water supply reliability, describes the City’s water shortage contingency plan (“WSCP”), and describes demand management measures. The purpose of the UWMP is to encourage local water agencies and wholesalers to plan ahead with respect to meeting future water supplies and demands and to report on the City’s compliance with the Water Conservation Act of 2009 (Senate Bill X7- 7) goal of achieving a 20 percent statewide reduction in urban per capita water use by the year 2020.

A Public Hearing is required prior to adopting the 2025 UWMP and WSCP.

WHEREAS, The 2025 UWMP incorporates standardized forms and tables as required by DWR and t he current update includes updated requirements compared to the previous UWMP guidance. These updated requirements are listed below:
• Changes in Water Code
• Suppliers with Multiple Public Water Systems
• DWR Submittal Tables
• Water Loss Standard Reporting
• Direct Potable Reuse
• Lower-Income Housing
• Reporting Groundwater Recharge and Other Water Storage;

WHEREAS, on March 23, 2026, the City entered into an agreement with Black Water Consulting Engineers, Inc. to prepare the City of Antioch’s 2025 Urban Water Management Plan. Submission of the adopted UWMP will fulfill compliance with the Urban Water Management Planning Act and support the City’s eligibility for applicable State water management grants and loans;
RESOLUTION NO. 2026/**
August 25, 2026

WHEREAS, in accordance with California Water Code Section 10621(b), the City notified Contra Costa County and other stakeholders (including Contra Costa Water District) that the City was preparing the 2025 UWMP more than 60 days prior to the date of Public Hearing. The Draft 2025 UWMP was made available to the public and interested parties for review and comment. A notice of public hearing was published in the local newspaper and posted at City facilities in accordance with Section 6066 of the Government Code; and

WHEREAS, within 30 days following adoption, the adopted 2025 UWMP will be submitted to DWR and the California State Library. Copies of the 2025 UWMP will be provided to: Contra Costa County and Contra Costa Water District and will be made available for public review on the City’s website at https://www.antiochca.gov/.

1 UWMP Introduction and Lay Description

1.1 Background and Purpose
Legal Requirements:

CWC Section 10615:
“Plan” means an urban water management plan prepared pursuant to this part. A plan shall describe and evaluate sources of supply, reasonable and practical efficient uses, reclamation, and demand management activities. The components of the plan may vary according to an individual community or area's characteristics and its capabilities to efficiently use and conserve water. The plan shall address measures for residential, commercial, governmental, and industrial water demand management as set forth in Article 2 (commencing with Section 10630) of Chapter 3. In addition, a strategy and time schedule for implementation shall be included in the plan.

The California Water Code (CWC) requires urban water suppliers within the state to prepare and adopt Urban Water Management Plans (UWMPs) for submission to the California Department of Water Resources (DWR). The UWMPs, which must be filed every five years, must satisfy the requirements of the Urban Water Management Planning Act (UWMPA) of 1983 including amendments that have been made to the UWMPA and other applicable regulations. The UWMPA requires urban water suppliers servicing 3,000 or more connections or supplying more than 3,000 acre -feet (AF) of water annually, to prepare a UWMP.

The purpose of the UWMP is to maintain efficient use of urban water supplies, continue to promote conservation programs and policies, ensure that sufficient water supplies are available for future beneficial use, and provide a mechanism for response during water drought conditions. This plan, which was prepared in compliance with the CWC, and as set forth in the 202 5 Urban Water Management Plan Guidebook for Urban Water Suppliers ( January 2026) established by DWR (UWMP Guidebook), constitutes the City of Antioch (City) 2025 UWMP. This 2025 UWMP was prepared in compliance with the UWMPA and the Water Conservation Bill of 2009 (Senate Bill [SB] X7 -7) by Black Water Consulting Engineers, Inc. and the City.

1.2 Previous Urban Water Management Plan
The City previous ly updated its 2020 UWMP in June 2021. Following adoption, the 20 20 UWMP was submitted to and approved by DWR. This 202 5 UWMP serves as an update to the 20 20 UWMP and complies with all new UWMP requirements and regulations.

1.3 Urban Water Management Planning and the California Water Code This section summarizes the CWC sections that are applicable to UWMPs.

1.3.1 Urban Water Management Planning Act of 1983
In 1983, State Assembly Bill (AB) 797 modified the CWC Division 6, by creating the UWMPA. Several amendments to the original UWMPA, which were introduced since 1983, have increased the data requirements and planning elements to be included in UWMPs. Initia l amendments to the UWMPA required that total projected water use be compared to water supply sources over the next 20 years, in City of Antioch

5-year increments. Recent DWR guidelines also suggest projecting through a 25-year planning horizon to maintain a 20-year timeframe until the next UWMP update has been completed. This is merely a guideline and not a requirement of the UWMPA. Therefore, the use of a 25-year planning horizon as opposed to a 20-year planning horizon is left up to the discretion of the agency. The City has opted to use a 20 -year planning horizon in this 2025 UWMP.

1.3.2 Applicable Changes to the Water Code Since the 2020 UWMP Since the UWMPA was enacted, the CWC has continued to evolve in response to statewide water management challenges such as prolonged drought, groundwater overdraft, regulatory updates, and changing climatic conditions. These factors influence each Supplier’ s water reliability determinations as well as the broader statewide reliability framework overseen by DWR, the State Water Resources Control Board (SWRCB), and the State of California Legislature (Legislature).

Summarized below are the major additions and changes to the UWMP requirements since the 2020 UWMP as per the DWR’s UWMP guidance documents:

• Changes in Water Code – There have been minor changes to the Water Code since the 2020 UWMPs were submitted; primarily, several definitions have been added. None of these change UWMP requirements for 2025 UWMPs.
• Suppliers with Multiple Public Water Systems (PWSs) – For consistency among State agencies, DWR and the State Water Board are using the same criteria to determine when a Supplier with multiple PWSs is considered an Urban Water Supplier subject to UWMP requirements. Refer to Chapter 2, Section 2.1.1 of the UWMP Guidebook for details. • DWR Submittal Tables – Submittal tables have been updated to reflect the current reporting year, improve accuracy of reporting, and more clearly identify information required by Water Code and optional information.
• Water Loss Standard Reporting – There has been no change to the Water Code regarding water loss standard reporting since 2020 UWMPs were submitted. However, the existing Water Code requires Suppliers to demonstrate compliance with the 2028 Water Loss Standard. The Water Loss Standards we re not available when the 2020 UWMPs were being submitted but are now available for 2025 UWMPs. Therefore, guidance has been added about how Suppliers can now report progress toward compliance with their Water Loss Standard in 2025 UWMPs. Refer to Submittal Table 4-6 and related guidance in Chapter 4 of the UWMP Guidebook. • Direct Potable Reuse – The State Water Board has adopted regulations for the use of direct potable reuse (DPR) since 2020 UWMP reporting. To allow for reporting of DPR, minor changes have been made to supply and demand tables. Refer to guidance in Chapters 4 and 6 of the UWMP Guidebook.
• Lower-Income Housing – While projections for lower -income housing were required in 2020 UWMPs, additional guidance has been provided for optional reporting of the method used to project water use for lower -income housing. This optional guidance incorporates the regional housing needs assessment into projected land uses and water demands. Refer to Chapter 4 and Appendix K of the UWMP Guidebook for more information.
• Reporting Groundwater Recharge and Other Water Storage – In previous years, the guidance for reporting water placed into storage did not differentiate between long -term storage (i.e., water placed into storage one year but extracted in a future year) and short -term storage (i.e., water that is placed into storag e and extracted the same year). When a Supplier reports water placed City of Antioch

into storage and then reports it was retrieved in the same year (short -term storage) it can cause a double counting error. Additional guidance recommending that Suppliers do not report water into and out of short -term storage is provided in Chapter 4 and C hapter 6 of the UWMP Guidebook.

1.4 UWMPs in Relation to Other Planning Efforts
The City is committed to providing a reliable and high-quality water supply to its customers and to ensure that the City will be able to reliably serve the residents of Antioch in the future . The City has conducted/participated in several efforts that relate to water supply planning in relation to the UWMP.

Some of the City’s planning efforts are summarized below:

• Water System Master Plan Update (prepared August 2014): The City completed a Water System Master Plan Update in 2014 to evaluate existing water system infrastructure, forecast future water demands through 2035, and identify capital improvements necessary to maintain reliable water service. The Master Plan also identified the need for continued rehabilitation and replacement of aging infrastructure, including raw water facilities, pumping stations, reservoirs, and distribution pipelines, while emphasizing water conservation and expanded recyc led water use to improve long-term supply reliability and operational resilience. [1] • General Plan (updated November 24, 2003): The City of Antioch General Plan establishes the long-term vision for land use, growth, infrastructure, and public services within the City. Since the last comprehensive General Plan update in 2003, Antioch has experienced significant changes in population, development patterns, economic conditions, regulatory requirements, and community priorities.
• East 18th Street Specific Plan (adopted July 2001): The East 18th Street Specific Plan established a framework for commercial, office/light industrial, circulation, and infrastructure improvements within the East 18th Street corridor. Since its adoption, portions of the Specific Plan area have been developed; however, undeveloped lands remain within the plan area. • East Lone Tree Specific Plan (adopted May 1996): Since its adoption in 1996, the East Lone Tree Specific Plan has largely been implemented, with most planned residential development and supporting infrastructure completed. Some remaining development potential exists within the commercial and employment -designated areas, particularly east of Highway 4, where undeveloped parcels remain.
• Hillcrest Station Area Specific Plan (adopted April 2009): The Hillcrest Station Area Specific Plan area is partially developed and remains an active growth area. While major infrastructure and transit improvements have been implemented, including the BART station area, additional residential, commercial, office, and mixed-use development opportunities remain. • Downtown Specific Plan (adopted February 13, 2018; updated November 12, 2024) : The Downtown Specific Plan is a twenty year plan and can change over time as needed to adapt to changes in the economy, market factors, technology, the needs and desires of the community.

1.6 Lay Description
Legal Requirements:

CWC Section 10630.5:

Each plan shall include a simple lay description of how much water the agency has on a reliable basis, how much it needs for the foreseeable future, what the agency’s strategy is for meeting its water needs, the challenges facing the agency, and any other information necessary to provide a general understanding of the agency’s plan.

The City provides potable water services to an established and growing residential, commercial, and industrial community located in Contra Costa County. Antioch is a mature East Bay city that has transitioned from a period of rapid expansion to more moderate growth. Based on the most recent United City of Antioch
2025 Urban Water Management Plan
August 2026

1-5

States (U.S.) Census and population estimates, the City currently serves a population of 118,958 residents, reflecting steady growth since the year 2010.

The City’s population is expected to increase modestly over the coming decades. As development continues, water demand is expected to increase, driven primarily by residential use, along with supporting commercial and industrial land use.

The City’s water system includes a water treatment plant (WTP), storage reservoirs, booster pump stations, and an extensive distribution network that serves a range of elevations and multiple pressure zones. The system serves an area of approximately 29.1 square miles and includes hundreds of miles of water mains that deliver treated water throughout the service area.

The City’s water supply consists primarily of surface water diverted from the San Joaquin River and water purchased from Contra Costa Water District (CCWD).

Untreated surface water from the San Joaquin River is pumped to the City’s Municipal Reservoir, where it is stored prior to treatment at the City’s WTP. This untreated surface water may also be routed to the Brackish Water Desalination Plant (BWDP), which was recently constructed at the City’s WTP and completed in September 2025. The BWDP includes a new intake and pumping facility and a reverse osmosis treatment system, allowing the City to treat San Joaquin River water year-round, including during periods of elevated salinity. The BWDP has a permeate capacity of 6 million gallons per day (MGD).

The City also purchases untreated water from CCWD via the Contra Costa Canal. This water can either be pumped to the Municipal Reservoir for storage or conveyed directly to the WTP for treatment and distribution. In addition, the City can purchase treated water from CCWD’s Randall-Bold Water Treatment Plant through an active intertie with the Multi-Purpose Pipeline (MPP). Under its agreement with CCWD, the City may purchase up to 10 MGD of treated water to supplement the City’s existin g treated water supply [2]. Figure 1-1 shows the locations of the Contra Costa Canal and the MPP that supplies water to the City from CCWD.

In addition to potable water supplies, the City works with Delta Diablo to utilize recycled water for landscape irrigation and other non-potable uses, further diversifying local water resources and supporting long-term water sustainability.

The City also maintains one (1) inactive emergency potable-water intertie with the City of Pittsburg and two (2) inactive interties with Diablo Water District.

Based on the evaluations completed in this Urban Water Management Plan, the City has sufficient water supplies to meet projected customer demands under normal water year conditions throughout the 20 - year planning horizon. The City also evaluated water supp ly reliability during single-dry years and a five- consecutive-year drought using historical drought conditions, projected water demands, and current supply capabilities. The analysis concludes that the City's diversified water supply portfolio, together with its existing treatment facilities, storage, purchased water agreements, and operational flexibility, provides sufficient supplies to meet projected demands during extended drought conditions.

3.5 Current and Projected Land Use
Legal Requirements:

CWC Section 10631(a):
…The description shall include the current and projected land uses within the existing or anticipated service area affecting the supplier’s water management planning. Urban water suppliers shall coordinate with local or regional land use authorities to dete rmine the most appropriate land use information, including, where appropriate, land use information obtained from local or regional land use authorities…

The City’s current and projected land uses are guided primarily by the City’s General Plan, specific plans, and related development policies. These land use documents establish the overall pattern of residential, commercial, industrial, mixed-use, open space, institutional, and recreational development within the City and its planning area. Because water demand is closely tied to location, type and intensity of development, land use planning is an important component of the City’s long -term water demand projections.

Existing land uses in the City include established residential neighborhoods, commercial corridors, public and institutional uses, parks, and recreational areas. Future land use planning within the City is guided by the Antioch General Plan and associated specific plans. Projected growth is expected to occur through a combination of infill development, redevelopment, and development of planned growth areas consistent with General Plan land use designations.

As development occurs, the City will continue to coordinate water planning with land use planning to ensure that water supplies, treatment capacity, shortage, distribution facilities, and conservation programs are adequate to serve existing and future cust omers. Figure 3 -2 shows a map of the City’s general land use.

4 Water Use Characterization

This chapter describes and quantifies the current and projected water demands within the City’s service area.

4.1 Non-Potable versus Potable Water Use
Potable water refers to water that is safe for human consumption and has undergone the necessary treatment and disinfection processes to comply with applicable drinking water standards.

The City primarily relies on potable water to meet municipal demands. Potable water, defined as treated drinking water suitable for human consumption, is supplied to all major customer sectors including residential, commercial, industrial, institutional, and lands cape irrigation uses. In 202 5, total potable water demand was approximately 5,311 million gallons (MG), representing the vast majority of system demand. Non-potable water use in Antioch consists primarily of recycled water supplied by the Delta Diablo for landscape irrigation at parks and the Lone Tree Golf Course. In 2025, recycled water use totaled approximately 87 MG, accounting for 1.6 percent of total system demand.

4.2 Past, Current, and Projected Water Use by Sector
Legal Requirements:

CWC Section 10635:
(a) Every urban water Supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years.

This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the long -term total projected water use over the next 20 years, in five -year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

CWC Section 10631(d):
(1) For an urban retail water supplier, quantify, to the extent records are available, past and current water use, over the same five -year increments described in subdivision (a), and projected water use, based upon information developed pursuant to subdiv ision (a), identifying the uses among water use sectors, including, but not necessarily limited to, all of the following… (2) The water use projections shall be in the same five-year increments described in subdivision (a). (4)(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area. (B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following: (i ) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections. (ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.

CWC Section 10635 (a)
Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years.

This water supply and demand assessment shall com pare the total water supply sources available to the water supplier with the long -term total projected water use over the next 20 years, in five -year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

Water Code Section 10631:
(h) An urban water supplier that relies upon a wholesale agency for a source of water shall provide the wholesale agency with water use projections from that agency for that source of water in five -year increments to 20 years or as far as data is available…

If a Retail Supplier receives water from a Wholesale Supplier, the Retail Supplier must provide their projected use of that supply to the Wholesale Supplier. Suppliers will report which wholesale suppliers were informed of their projected use using Submittal Table 2-4 R.

CWC Section 10631(d)(4):
(A) Water use projections, where available, shall display and account for the water savings estimated to result from adopted codes, standards, ordinances, or transportation and land use plans identified by the urban water supplier, as applicable to the service area. (B) To the extent that an urban water supplier reports the information described in subparagraph (A), an urban water supplier shall do both of the following:
(i) Provide citations of the various codes, standards, ordinances, or transportation and land use plans utilized in making the projections.
(ii) Indicate the extent that the water use projections consider savings from codes, standards, ordinances, or transportation and land use plans. Water use projections that do not account for these water savings shall be noted of that fact.

Projected future water demands were estimated using an annual population growth rate of 0.65 percent, consistent with the City's anticipated growth and development patterns within the service area.

4.2.7 Climate Change Considerations
Legal Requirements:

CWC Section 10630:

It is the intention of the Legislature, in enacting this part, to permit levels of water management planning commensurate with the numbers of customers served and the volume of water supplied, while accounting for impacts from climate change.

CWC Section 10635(b):

Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment … (and) shall include each of the following… (4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

Climate change is expected to affect long-term management in Antioch. The City’s water supply planning may be influenced by higher temperatures, longer dry periods, more frequent droughts, precipitation patterns, sea level rise, and changes in San Joaquin River water quality. These conditions may affect both customer water demand and the reliability of available supplies.

Higher temperatures can increase outdoor water use, especially during the summer and early fall when landscape irrigation demand is highest. Longer dry periods may also increase the need for irrigation and place additional pressures on regional water suppl ies. At the same time, changes in precipitation may affect freshwater flows into the San Joaquin River.

Surface water quality is an especially important climate -related issue for the City. During dry years or periods of reduced freshwater outflow, salinity can increase in the surface water . To address this challenge, the City recently constructed the BWDP, which allows the City to treat San Joaquin River water year-round, including during periods of elevated salinity.

The City also addresses climate -related water management challenges through conservation, recycled water use, water loss control, regional coordination, capital improvements, and implementation of the Water Shortage Contingency Plan. These actions help reduce dema nd on potable supplies and improve the City’s ability to respond to changing hydrological and climate conditions.

5 SB X7-7 Baselines, 2020 Targets, and 2025 Reporting

With the adoption of the Water Conservation Act of 2009, also known as SB X7-7, the State of California was required to reduce urban per capita water use by 20 percent by the year 2020 (i.e., “20 by 2020”).

CWC Section 10608.16(a) states: “The state shall achieve a 20-percent reduction in urban per capita water use in California on or before December 31, 2020.” To achieve this statewide objective, the California Legislature required each urban retail water supplier subject to the U WMPA to develop an urban water use target to help the state collectively achieve a 20-percent reduction.

This chapter provides a description of the methodology used to calculate the City’s compliance with SB X7-7 requirements.

5.1 Baseline and Target Calculations for 2025 UWMPs
Legal Requirements:

CWC Section 10608.40:

Urban water retail suppliers shall report to the department on their progress in meeting their urban water use targets as part of their urban water management plans submitted pursuant to Section 10631.

CWC Section 10608.12:
(af) “Urban retail water supplier” means a water supplier, either publicly or privately owned, that directly provides potable municipal water to more than 3,000 end users or that supplies

The City is required under the CWC to report its progress toward achieving the 2020 water use reduction target. In its 2020 UWMP, the City established SB X7 -7 baselines and a 2020 target of 165 gallons per capita per day (gpcd). The City met the requirements of California Water Code Section 10608.16(a) to achieve a 20 percent reduction in urban per capita water use by 2020 . This reduction reflects both long- term efficiency improvements and temporary conservations measures implemented during statewide drought conditions, many of which resulted in reductions per capita demand.

Table 5-1 (DWR Table 5-1 Retail) summarizes the targeted water use value as well as the actual water use in 2020 to confirm the target was achieved.

NOTES: City does not incorporate groundwater into its water usage.

6.1.3 Surface Water
The City has diverted water from the San Joaquin River since the 1870s and as such, has pre -1914 water rights [1]. A copy of the City’s water rights documentation is included in Appendix E. The Division of Water Rights’ records do not specify a fixed diversion quantity.

As discussed in Section 1.6, the City receives untreated surface water from the San Joaquin River. This water can either be pumped to the City’s Municipal Reservoir for storage prior to treatment or conveyed to the BWDP. The City completed construction of the BWDP in September 2025 to allow year -round treatment of the San Joaquin River water, including during periods of elevated salinity. The BWDP has a permeate capacity of 6 mgd.

Prior to completion of the BWDP, the City’s use of San Joaquin River water was constrained by intake capacity and the inability of the conventional water treatment process to remove salinity. During periods when river salinity exceeded the City’s water qua lity targets, the City relied more heavily on purchased water from CCWD.

City of Antioch
2025 Urban Water Management Plan
August 2026

6-4

With completion of the BWDP, the City has improved its ability to use surface water from the San Joaquin River during high-salinity periods by treating brackish river water to drinking water standards.

6.1.4 Stormwater
The four creeks that receive local runoff are the East Antioch Creek, Markley Creek, Sand Creek, and West Antioch Creek. Storm water from these local creeks flows untreated into the San Joaquin River. Currently, the City does not implement stormwater recovery to offset potable use.

CWC Section 10633 (c):

A description of the recycled water currently being used in the supplier’s service area, including, but not limited to, the type, place, and quantity of use.

The City collects wastewater within its service area and conveys it to the Delta Diablo WWTP for treatment. The Delta Diablo produces recycled water that is used within Antioch for non-potable irrigation purposes. Existing recycled water uses include irrigation of City parks and a golf course. The City reported 87 MG of recycled water use in 2025.

6.1.5.4 Current, Potential, and Projected Recycled Water Uses Legal Requirements:

CWC Section 10633:
(b) A description of the quantity of treated wastewater that meets recycled water standards, is being discharged, and is otherwise available for use in a recycled water project. (d) A description and quantification of the potential uses of recycled water, including, but not limited to, agricultural irrigation, landscape irrigation, wildlife habitat enhancement, wetlands, industrial reuse, groundwater recharge, indirect potable reu se, and other appropriate uses, and a determination with regard to the technical and economic feasibility of serving those uses. (e) The projected use of recycled water within the supplier’s service area at the end of 5, 10, 15, and 20 years, and a description of the actual use of recycled water in comparison to uses previously projected pursuant to this subdivision.

Delta Diablo supplies tertiary -treated recycled water to the City to irrigate Fairview Park, City Park, Mountaire Park, Chichibu Park, and the Lone Tree Golf Course.

Although the City is currently using recycled water for landscape application , due to the comparatively high costs associated with developing and delivering recycled water for use within the City, relative to existing wastewater disposal practices, the City does not currently plan to implement additional improvements to support local recycled water distribution. Based on the City’s current conditions, findings from prior studies, applicable and anticipated regulatory requirements, and evaluation of the costs associated with potentially feasible alternatives, recycled water will only be used for the existing applications at this time.

6.1.11 Special Conditions
The City’s BWDP helps treat higher-salinity surface water from the San Joaquin River. This facility provides additional operational flexibility and supports long-term supply reliability. The City also coordinates with CCWD, Delta Diablo, and neighboring agencies to support regional water supply, purchased water reliability, and recycled water use.

6.2 Energy Use
Legal Requirements:

CWC Section 10631.2. (a):

In addition to the requirements of Section 10631, an urban water management plan shall include any of the following information that the urban water supplier can readily obtain:
(1) An estimate of the amount of energy used to extract or divert water supplies. (2) An estimate of the amount of energy used to convey water supplies to the water treatment plants or distribution systems.
(3) An estimate of the amount of energy used to treat water supplies. (4) An estimate of the amount of energy used to distribute water supplies through its distribution systems.
(5) An estimate of the amount of energy used for treated water supplies in comparison to the amount used for nontreated water supplies.
(6) An estimate of the amount of energy used to place water into or withdraw from storage. (7) Any other energy-related information the urban water supplier deems appropriate.

Water energy intensity represents the total amount of energy expended, calculated on a whole -system basis, to deliver water to customers. Energy intensity is expressed in kilowatt -hours per acre -foot and reflects the energy required to convey water from it s source through treatment and distribution to the point of delivery. Evaluating whole-system energy intensity enables the City to make informed decisions in managing its water supplies and operating its facilities, including:

• Identifying opportunities to reduce energy consumption, which represents a significant portion of water delivery costs;
• Estimating energy savings and greenhouse gas emission reductions associated with water conservation programs;
• Supporting applications for grants related to energy efficiency and water conservation initiatives; • Informing climate change mitigation and adaptation strategies; and • Benchmarking energy use across individual water supply, treatment, and distribution components and comparing performance with similar agencies.

Energy intensity was calculated using the tables provided by DWR. DWR Table O -1B was selected for reporting the water delivery product energy usage and Table O -2 was selected for reporting the wastewater energy usage. The energy use tables for retail water delivery, wastewater, and recycled water are provided in Appendix F.

As discussed in Section 6. 1.5, recycled water is used within the City’s service area for approved non - potable uses, including landscape irrigation of parks and a golf course. The City does not produce its own recycled water; the City only needs to supply energy associated with City -operated recycled water distribution facilities. Recycled water treatment processes are performed by Delta Diablo.

7.1 Constraints on Water Sources
Legal Requirements:

CWC Section 10631 (b)(1):

A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change.

Water Code Section 10634
The plan shall include information, to the extent practicable, relating to the quality of existing sources of water available to the supplier over the same five-year increments as described in subdivision (a) of Section 10631, and the manner in which water quality affects water management strategies and supply reliability.

Water Code Section 10635 (b)(2)
A determination of the reliability of each source of supply under a variety of water shortage conditions.

This may include a determination that a particular source of water supply is fully reliable under most, if not all conditions.

Water Code Section 10635 (b)(4)
Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

There are several factors that can affect the reliability of the City’s water supplies. These factors include legal and water-rights considerations, environmental and regulatory conditions in the San Joaquin River, water quality constraints, facility capacity, and climatic variability. Since the City’s potable supplies are tied to the San Joaquin River intake or indirectly through CCWD, reliability planning must consider both local operating constraints and conditions.

7.1.1 Legal
The City’s water supplies are subject to applicable water rights, contracts, drinking water regulations, environmental requirements, and State reporting requirements. These requirements may affect the availability, treatment, and use of the surface water from the San Joaquin River , purchased water from CCWD, and recycled water coordinated through Delta Diablo.

City of Antioch
2025 Urban Water Management Plan
August 2026

7-2

The City manages these legal and regulatory constraints through regional coordination, water treatment improvements, conservation, recycled water use, and implementation of its WSCP. Changes in regulatory requirements may affect future operation and capital improvements.

7.1.2 Environmental
The City relies on a combination of San Joaquin River diversions and water purchased through the Contra Costa Canal system. During periods of drought, reduced freshwater inflows, or elevated salinity conditions in the Delta, the availability of suitable source wat er may be constrained. To address these potential challenges, the City maintains multiple water supply sources and completed the BWDP project to improve water supply reliability and resiliency under changing environmental conditions.

7.1.3 Water Quality
The 2024 CCWD Annual Water Quality Report states that drinking water delivered in 2024 met or exceeded all applicable state and federal drinking water standards. For Antioch, the report explains that the City primarily purchases untreated water from CCWD, treats it at a City-owned treatment plant, and delivers it through the City’s distribution system. Antioch can also pump directly from the San Joaquin River or purchase treated water from CCWD [2].

Refer to Appendix G for the CCWD 2020-2024 Annual Water Quality Reports.

7.1.4 Climatic Factors
Refer to Section 4.2.7 of this UWMP for climate change considerations.

7.2 Water Service Reliability Assessment (WSRA)
Legal Requirements:

CWC Section 10635(a):

Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years.

This water supply and demand assessment shall com pare the total water supply sources available to the water supplier with the long -term total projected water use over the next 20 years, in five -year increments, for a normal water year, a single dry water year, and a drought lasting five consecutive water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional, or local agency population projections within the service area of the urban water supplier.

Expected water service reliability pursuant to Section 10635 of the Water Code is assessed in the following sections.

7.2.1 WSRA Year-Type Characterization
This section addresses the reliability of the City’s water supply in average, single dry, and multiple dry water years. The City uses the following water year definitions from the DWR 2025 Guidebook:

• Normal Year: a year, or an averaged range of years, that most closely represents the average water supply available to the agency. For the purposes of this UWMP, the terms “normal” and “average” are used interchangeably.
• Single-Dry Year: the year that represents the lowest water supply available to the agency.

7.2.3 Description of Management Tools and Options
Legal Requirements:

CWC Section 10620(f):

An urban water supplier shall describe in the plan water management tools and options used by that entity that will maximize resources and minimize the need to import water from other regions.

The City of Antioch utilizes a variety of water management tools and options to maximize available water resources and minimize reliance on imported water supplies. These tools include water conservation programs, water loss control measures, system mainte nance and rehabilitation, and long -term water supply planning.

7.3 Drought Risk Assessment
Legal Requirements:

CWC Section 10612
“Drought Risk Assessment” means a method that examines water shortage risks based on the driest five-year historic sequence for the agency’s water supply, as described in subdivision (b) of Section 10635.

City of Antioch
2025 Urban Water Management Plan
August 2026

7-7

CWC Section 10635(b):

Every urban water supplier shall include, as part of its urban water management plan, a drought risk assessment for its water service to its customers as part of information considered in developing the demand management measures and water supply projects and programs to be included in the urban water management plan. The urban water supplier may conduct an interim update or updates to this drought risk assessment within the five -year cycle of its urban water management plan update. The drought risk assessment shall include each of the following:
(1) A description of the data, methodology, and basis for one or more supply shortage conditions that are necessary to conduct a drought risk assessment for a drought period that lasts five consecutive water years, starting from the year following when the assessment is conducted. (2) A determination of the reliability of each source of supply under a variety of water shortage conditions. This may include a determination that a particular source of water supply is fully reliable under most, if not all, conditions.
(3) A comparison of the total water supply sources available to the water supplier with the total projected water use for the drought period.
(4) Considerations of the historical drought hydrology, plausible changes on projected supplies and demands under climate change conditions, anticipated regulatory changes, and other locally applicable criteria.

This section provides a D rought Risk Assessment (DRA) based on the five driest consecutive years on record and plausible changes in climate, regulations, and other locally applicable criteria. A description of the data and methods used, basis for the supply shortage conditions, determination of the reliability of each source, and comparison of total water supplies and uses during a drought are provided below.

7.3.1 DRA Data, Methods, and Basis for Water Shortage Conditions The DRA was prepared using the City’s historical supply records, projected water demands, and water source reliability assumptions developed in Chapter 4, 6, and 7 of this UWMP. The analysis uses the 2012 through 2016 drought period as the representative five consecutive year drought sequence. The City’s 2025 UWMP identified 2012 through 2016 as the driest five-year historical drought sequence for Antioch’s water supply planning and evaluated the reliability of surface water from the San Joaquin River, purchase water from CCWD, and recycled water from Delta Diablo supplies under that sequence.

7.3.2 DRA Water Source Reliability
The City’s water supply reliability during a five-year drought depends on the performance of each source in the City’s portfolio. For example, the BWDP has improved reliability by allowing the City to treat and use brackish surface water during periods when elevated salinity would otherwise limit direct use. This increases operational flexibility, strengthens drought resilience, and reduces reliance on purchased water during high-salinity conditions.

7.3.3 Total Water Supply and Use Comparison
The total water supply and use comparison for the next five years under drought conditions is shown in Table 7-5 (DWR Table 7-5 Retail). The comparison indicates that the City , under current water shortage conditions, does have sufficient water supply to meet projected demands during a five-year drought. The WSCP further discusses measures for reducing water demands with the implementation of water shortage conditions.

8 Water Shortage Contingency Plan

In response to the severe drought of 2012 -2016, legislation was adopted in 2018 mandating that the UWMP include a Water Shortage Contingency Plan (WSCP) that provides a detailed proposal for assessing water supply availability and response actions to water shortage conditions.

8.1 Introduction
The WSCP defines how the City will respond in the case of an actual water shortage. A water shortage means that the water supply available is insufficient to meet the normally expected customer water use at a given point in time. The WSCP provides guidance for managing and mitigating a potential shortage of water supply.

Pursuant to CWC Section 10632, the WSCP is required to include the following elements:

• Key attributes of the water supply reliability analysis conducted pursuant to CWC Section 10632(a)(1), which evaluates the Supplier’s ability to meet demands under varying hydrologic and operational conditions.
• Six standard water shortage levels correspond to progressive shortages of up to 10, 20, 30, 40, and 50 percent, and shortages greater than 50 percent. [CWC Section 10632(a)(3)(A)] • Locally appropriate shortage response actions for each shortage level, including supply augmentation, demand reduction, operational changes, and mandatory water -use prohibitions, along with estimates of the extent to which each action addresses the supply-demand gap. [CWC Section 10632(a)(4)]
• Procedures for conducting an Annual Water Supply and Demand Assessment (AWSDA), including the data and methods used to evaluate supply reliability. Urban water suppliers are required to submit an Annual Water Shortage Assessment Report (AWSAR) to the California Department of Water Resources (DWR) by July 1 of each year, beginning i n the year following adoption of the 2020 UWMP. [CWC Sections 10632(a)(2) and 10632.1]
• Communication protocols and procedures to inform customers, the public, and government entities of current or anticipated water shortages and associated response actions. [CWC Section 10632(a)(5)]
• Monitoring and reporting procedures to ensure appropriate data collection, track customer compliance, evaluate the effectiveness of response actions, and meet applicable state reporting requirements. [CWC Section 10632(a)(9)]
• A re -evaluation and improvement process to periodically assess the performance and functionality of the WSCP and to adjust based on observed conditions, monitoring results, and evolving risks. [CWC Section 10632(a)(10)]

8.2 Water Supply Reliability Analysis

Legal Requirements:

Water Code Section 10632(a)(1)
The analysis of water supply reliability conducted pursuant to Section 10635.

Water Code Section 10632.5(a)
In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a seismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.

In accordance with CWC Section 10632(a)(1), this section presents findings from the City’s water system reliability analysis and identifies the key factors that may contribute to future water shortage conditions.

This evaluation incorporates projected water use trends from Chapter 4 of the UWMP, the inventory of current and planned water supply sources outlined in Chapter 6, and the water supply reliability and drought risk assessments presented in Chapter 7. The reliability assessment spans the years 2030 through 2050, while the drought risk assessment covers the five -year period from 2026 to 2030. Together, these elements provide a comprehensive understanding of the City’s water resource capacity and its preparedness to respond to potential shortage scenarios.

When water supply shortfalls are anticipated or observed, the City may declare a water shortage level in accordance with this WSCP, as described in Section 8.4. In response to identified reliability challenges, the City and the Contra Costa Water District continue to evaluate additional supply, operational, and water management strategies, as documented in Chapter 7 of the City’s 2025 UWMP.

The City’s 2025 UWMP evaluated the long-term (20-year) and near-term (5-year) supply reliability of the City’s water system, including consideration for a normal year, single dry year, and a 5 -year dry period and concluded that the City can reliably meet its projected water demands.

8.3 Annual Water Supply and Demand Assessment Procedures

Legal Requirements:

Water Code Section 10632 (a)
Every urban water supplier shall prepare and adopt a water shortage contingency plan as part of its urban water management plan that consists of each of the following elements

Water Code Section 10632(a)(2)
The procedures used in conducting an annual water supply and demand assessment that include, at a minimum, both of the following:

(A) The written decision-making process that an urban water supplier will use each year to determine its water supply reliability.
(B) The key data inputs and assessment methodology used to evaluate the urban water supplier’s water supply reliability for the current year and one dry year, including all of the following:
(i) Current year unconstrained demand, considering weather, growth, and other influencing factors, such as policies to manage current supplies to meet demand objectives in future years, as applicable. (ii) Current year available supply, considering hydrological and regulatory conditions in the current year and one dry year. The annual supply and demand assessment may consider more than one dry year solely at the discretion of the urban water supplier.
(iii) Existing infrastructure capabilities and plausible constraints. (iv) A defined set of locally applicable evaluation criteria that are consistently relied upon for each annual water supply and demand assessment.
(v) A description and quantification of each source of water supply.

Water Code Section 10632.1.

An urban water supplier shall conduct an annual water supply and demand assessment pursuant to subdivision (a) of Section 10632 and, on or before July 1 of each year, submit an annual water shortage assessment report to the department with information for anticipated shortage, triggered shortage response actions, compliance and enforcement actions, and communication actions consistent with the supplier’s water shortage contingency plan. An urban water supplier that relies on imported water from the State Water Project or the Bureau of Reclamation shall submit its annual water supply and demand assessment within 14 days of receiving its final allocations, or by July 1 of each year, whichever is later.

CWC Section 10632.1 requires the City to conduct an A WSDA on or before July 1 of each year and to submit an AWSAR to the California DWR by July 1 annually. The purpose of the AWSDA and AWSAR is to evaluate near-term water supply reliability for the upcoming year and to ensure that appropriate water shortage response actions are identified and implemented in a timely manner, if warranted.

This section of the WSCP describes the procedures used by the City to prepare the AWSDA and AWSAR.

These procedures are intended to establish a clear, consistent process for the annual evaluation of water supply and demand conditions, including the timing, data sources, analytical steps, and decision -making framework used to determine water supply reliability and potential shortage conditions.

8.3.1 Decision-Making Process
The City is responsible for preparation, obtaining formal approval, and submitting the AWSAR to the DWR.

Key responsibilities for preparation of the AWSDA and AWSAR are listed in Table 8-1. Early in the process, the key team members will be selected and assigned responsibilities to ensure accurate and timely completion of the documents. Each AWSAR should include a summary of the key members involved and their roles and responsibilities.

Figure 8-1 – Example AWSDA and AWSAR Timeline

8.3.2 Data and Methodologies
In preparing the AWSDA, the City will apply the methodologies and evaluation criteria described in this section to assess water supply reliability for the current year and one subsequent dry year. The key data inputs and analytical methods used in this assessment are described below.

• Step 1. Determine Water Allocation for the City – The type of water year for the San Joaquin River and the CCWD water supply
• Step 2. Gather Key Data Inputs – The City collects key data inputs for the Annual Assessment including water supply and unconstrained customer demand as described below.

City of Antioch
2025 Urban Water Management Plan
August 2026

8-5

o Step 2a. Estimate Unconstrained Customer Demand – The City estimates current year unconstrained demand considering weather, growth, and other influencing factors such as policies to manage current supplies to meet demand objectives in future years, as applicable. Unconstrained customer demand does not include demand reductions that may occur as a result of the City implementing any necessary special shortage response actions.
o Step 2b. Quantify Supplies Needed – The City estimates the available water supply by source for the current year and one subsequent dry year. ▪ Quantify each source of water supply and provide descriptive text of each source ▪ Quantify current year available supply by source, considering hydrological and regulatory conditions in the current year
▪ Quantify available supply by source for one subsequent dry year. ▪ Estimate water supply availability estimates by source:
• The existing infrastructure capabilities and plausible constraints as they impact the City’s ability to deliver supplies to meet expected customer water use needs in the coming year should be considered. • Hydrological and regulatory conditions in the current year • Specific locally applicable factors that can influence or disrupt each supply source
• Step 3. Apply Evaluation Criteria – Evaluation criteria are determined by the supply source conditions and factors that impact the condition of each supply source. The Annual Assessment is based on evaluating the key data inputs to determine the water supply reliability. Although an actual shortage may occur at any time during the year, the City usually can forecast a shortage on or about May 1 of each year.
• Step 4. Prepare Draft Annual Assessment Report – The City will compile the draft Annual Assessment report based on the format to be determined by DWR using the key data inputs and evaluation criteria. The City will review and provide comments on the draft Annual Assessment report.
• Step 5. Finalize Annual Assessment Report – The City will address internal comments to the draft Annual Assessment report and will finalize the report.
• Step 6. Submit Annual Assessment Report to DWR – The City will submit the Annual Assessment report to DWR.

8.4 Six Standard Water Shortage Levels

Legal Requirements:

Water Code Section 10632(a)(3)
(A) Six standard water shortage levels corresponding to progressive ranges of up to 10, 20, 30, 40, and 50 percent shortages and greater than 50 percent shortage. Urban water suppliers shall define these shortage levels based on the suppliers’ water supply conditions, including percentage reductions in water supply, changes in groundwater levels, changes in surface elevation or level of subsidence, or other changes in hydrological or other local conditions indicative of the water supply available for use.

Shortage levels shall also apply to catastrophic interruption of water supplies, including, but not limited to, a regional power outage, an earthquake, and other potential emergency events.

(B) An urban water supplier with an existing water shortage contingency plan that uses different water shortage levels may comply with the requirement in subparagraph (A) by developing and including a cross-reference relating its existing categories to the six standard water shortage levels.

To provide a consistent regional and statewide framework for communicating the severity of water supply shortage conditions, the 2018 Water Conservation Legislation requires urban water suppliers to define six standard water shortage levels corresponding to progressive ranges of water supply shortages. CWC Section 10632(a)(3) requires these shortage levels to be based on the supplier’s water supply conditions and may consider factors such as percentage reductions in available water supply, ch anges in groundwater levels, changes in surface water elevations, land subsidence, or other hydrologic or local conditions indicative of the water supply available for use.

In accordance with these requirements, the City has developed the six standard water shortage levels established by the California DWR for inclusion in WSCPs in 2025. These standard shortage levels correspond to progressive water supply shortages of up to 10 percent, 20 percent, 30 percent, 40 percent, 50 percent, and greater than 50 percent from normal reliability conditions. The standard water shortage levels used by the City are consistent with those presented in Table 8-2 (DWR Table 8-1).

Shortage response actions that align with the defined shortage levels and include, at a minimum, all of the following:

(A) Locally appropriate supply augmentation actions.

(B) Locally appropriate demand reduction actions to adequately respond to shortages.

(C) Locally appropriate operational changes.

(D) Additional, mandatory prohibitions against specific water use practices that are in addition to state- mandated prohibitions and appropriate to the local conditions.

(E) For each action, an estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the action.

Water Code Section 10632.2
An urban water supplier shall follow, where feasible and appropriate, the prescribed procedures and implement determined shortage response actions in its water shortage contingency plan, as identified in subdivision (a) of Section 10632, or reasonable alternative actions, provided that descriptions of the alternative actions are submitted with the annual water shortage assessment report pursuant to Section 10632.1. Nothing in this section prohibits an urban water supplier from taking actions not specified in its water short age contingency plan, if needed, without having to formally amend its urban water management plan or water shortage contingency plan.

CWC Section 10632(a)(4) requires shortage response actions that align with the shortage levels defined in Table 8-2 (DWR Table 8 -1) and include locally appropriate supply augmentation actions, demand reduction actions, operational changes, and additional mandatory prohibitions against specific water use practices. An estimate of the extent to which the gap between supplies and demand will be reduced by implementation of the actions must be provided.

8.5.1 Supply Augmentation Actions
During water shortage conditions, the City may continue using recycled water supplied by Delta Diablo to offset potable demand for approved non-potable uses. The City may also evaluate temporary transfers or purchased supplies from other agencies, subject to availability, infrastructure capacity, regulatory approvals, and cost. Public outreach would support these actions by increasing awareness and improving the effectiveness of demand reduction measures.

Additional supply augmentation and other actions that the City may implement during water shortage emergencies are summarized in Table 8-3 (DWR Table 8-2). These actions are intended to complement demand reduction and operational measures and may be implemented individually or in combination, depending on the severity and duration of the water shortage condition.

8.5.4 Seismic Risk Assessment and Mitigation Plan
Water Code Section 10632.5
(a) In addition to the requirements of paragraph (3) of subdivision (a) of Section 10632, beginning January 1, 2020, the plan shall include a seismic risk assessment and mitigation plan to assess the vulnerability of each of the various facilities of a water system and mitigate those vulnerabilities.

(b) An urban water supplier shall update the seismic risk assessment and mitigation plan when updating its urban water management plan as required by Section 10621.

(c) An urban water supplier may comply with this section by submitting, pursuant to Section 10644, a copy of the most recent adopted local hazard mitigation plan or multihazard mitigation plan under the federal Disaster Mitigation Act of 2000 (Public Law 1 06-390) if the local hazard mitigation plan or multihazard mitigation plan addresses seismic risk.

The City has prepared a seismic risk assessment as part of its confidential Risk and Resilience Assessment (RRA) in compliance with America's Water Infrastructure Act (AWIA) of 2018, Public Law 115-270, S. 3021.

The AWIA law requires a community water system (CWS) serving more than 100,000 people to develop an RRA and an ERP. In compliance with AWIA, as a CWS serving a population of 100,000 or more, the City prepared and certified the required RRA to the U.S. Environmental Protection Agency by March 1, 2025.

Similarly, the City prepared and certified its ERP by September 30, 2025. As part of the RRA and ERP, the City evaluated seismic risk to its facilities and mitigation measures to reduce the impacts of the earthquake threat.

The Contra Costa County 2024 Hazard Mitigation Plan (HMP) [9] identifies hazards that may affect Antioch and the broader county, including drought, flooding, earthquake, wildfire, severe weather, sea level rise, dam and levee failure, and utility interruptions. The plan supports regional resilience by assessing risks and identifying mitigation actions to reduce impacts to people, property, infrastructure, and essential services.

The City’s RRA went a little deeper by identifying specific assets and risks associated with seismic activity.

Per the RRA earthquake is the City’s costliest threat. The cost is not as significant on an asset basis, but when added together, earthquakes have the potential to impact several assets simultaneously. The RRA determined that many of the City’s facilities are at risk to earthquake threat:

• CCWD Canal Pumping Stations

8.6 Communication Protocols
Water Code Section 10632 (a)(5)
Communication protocols and procedures to inform customers, the public, interested parties, and local, regional, and state governments, regarding, at a minimum, all of the following:

(A) Any current or predicted shortages as determined by the annual water supply and demand assessment described pursuant to Section 10632.1.

(B) Any shortage response actions triggered or anticipated to be triggered by the annual water supply and demand assessment described pursuant to Section 10632.1.

(C) Any other relevant communications

Timely and effective communication is a key element of WSCP implementation. The City has structured its communication protocols and procedures in the event of a water shortage to activate through authorization by the WTP Superintendent. Under a water shortage condition, the WTP superintendent, working with other City staff, would assess the actual water supply and demand information and conditions to determine whether the City should activate the WSCP. If so, City staff would recommend activation of the appropriate stage alert, and request City Council authorization to initiate the measures necessary to achieve the appropriate demand reduction target. The City would encourage the public to understand and participate in the decision -making process and provide feedback to the City Council on such an action. The WSCP is flexible and can be implemented to best match actual conditions of a particular water shortage event.

Specific communication protocols to inform customers, the public, interested parties, and local, regional, state governments of any current or projected shortage as determined by the annual water supply and demand assessment described in Section 8.3 and any shortage response actions as a result of the annual assessment are listed below:

• Expanded public information and awareness program by implementing workshops, distributing park signs, adding bill inserts, and increasing the number of educational programs at schools. Use of social media and e -mail blasts to customers. Further explanation of these tools are described in Section 9.
• Customer billing frequency increased from bi-monthly to monthly to provide a better estimate of water losses and quicker detection of a leak or water loss.

Critical communication information is included in the City’s ERP as discussed in Section 8.5.3.

8.9 Financial Consequences of WSCP

Legal Requirements:

Water Code Section 10632(a)(8)
A description of the financial consequences of, and responses for, drought conditions, including, but not limited to, all of the following:

(A) A description of potential revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4).

(B) A description of mitigation actions needed to address revenue reductions and expense increases associated with activated shortage response actions described in paragraph (4).

(C) A description of the cost of compliance with Chapter 3.3 (commencing with Section 365) of Division

1. The financial consequence of implementing the WSCP include potential revenue reductions and expense increases. The City has developed mitigation actions to reduce these impacts and the cost of compliance.

8.9.1 Potential Revenue Reductions and Expense Increases The City understands the projected ranges of water sales by shortage stage and what the impact would be on projected revenues and expenditures by each shortage level. Revenues would decrease as consumption is decreased. Expenditures would increase as response actions are implemented.

8.9.2 Mitigation Actions
In Levels 1 and 2 conditions, the City would attempt to avoid rate adjustments. However, if the water shortage conditions persisted and/or became more severe thereby further reducing demands, rate changes would be imperative.

• Use of Financial Reserves - The City has financial reserves to address decreased water sales during a water shortage.
• Other Measures - The City does not have additional measures formalized such as drought rate surcharges, postponement of capital improvements, or reduction of agency staff.

8.10 Monitoring and Reporting

Legal Requirements:

Water Code Section 10632(a)(9)
For an urban retail water supplier, monitoring and reporting requirements and procedures that ensure appropriate data is collected, tracked, and analyzed for purposes of monitoring customer compliance and to meet state reporting requirements.

The City will monitor and report implementation of the WSCP by collecting, tracking, and analyzing appropriate data to monitor customer compliance and to meet state reporting requirements. Under normal water supply conditions, City staff record potable water production figures daily. The City reports daily production totals monthly. The City operates its water system on a computerized supervisory control and data acquisition system (SCADA), which allows instantaneous viewing of water system conditions.

During Level 2 of a water shortage, the WTP Superintendent evaluates production figures to determine if City water users meet demand reduction targets. The WTP Superintendent reviews the monthly production reports and determines if further action is required to meet d emand reduction goals. If City water users do not meet reduction goals, the WTP Superintendent will notify the City Council so that corrective action is considered and/or taken.

As a water shortage progresses to Level 4, the City would follow the procedure described above, with the addition of a weekly production report to the WTP Superintendent.

During emergency shortages ( Level 6), the WTP Superintendent reviews production figures and reports to the City Manager.

Legal Requirements:

Water Code Section 10632 (a)(10)
Reevaluation and improvement procedures for systematically monitoring and evaluating the functionality of the water shortage contingency plan in order to ensure shortage risk tolerance is adequate and appropriate water shortage mitigation strategies are implemented as needed.

This WSCP is intended to function as an adaptive management document and may be refined as necessary to ensure that the City’s shortage response actions and mitigation strategies remain effective and achieve the intended outcomes. Based on monitoring activities described in Section 8.10, as well as compliance and enforcement results described in Section 8.7, the City may adjust response actions and revise this WSCP to address changing conditions, implementation challenges, or observed performance.

When revisions to the WSCP are proposed, the updated plan will undergo the adoption process described in Section 8.13, including consideration by the City Council and distribution to Contra Costa County, City customers, and the general public, as applicable.

Feedback from the City staff and the public is an important component of the WSCP refinement process.

The City will seek input from staff who regularly interact with customers and implement water shortage response actions to assess the practicality and effectiveness of existing measures and to identify potential improvements or new actions.

Customer water use data may be evaluated by customer sector or by individual account to assess the effectiveness of demand reduction measures and compliance trends. The City will track water use violations and may evaluate their frequency and characteristics to identify restrictions that may be difficult for customers to comply with, as well as demand reduction actions that are particularly effective.

The City will also seek input from customers and the general public through its website and during regularly scheduled City Council meetings to inform future refinements to the WSCP.

9 Demand Management Measures

This chapter describes the City ’s historical and existing Demand Management Measures (DMMs) implemented to promote water conservation and reduce demands on available water supplies. The discussion includes past, current, and projected DMMs. These measures are a key component of the City’s long-term water supply planning and are also integral to the effectiveness of the Water Shortage Contingency Plan, which is summarized in Chapter 8.

In prior UWMPs, water suppliers were required to provide extensive data documenting progress in implementing specific DMMs. However, AB 2067, enacted in 2014, simplified and updated DMM reporting requirements. The revised framework shifted the focus from d etailed documentation of individual measures to implementation of core conservation actions designed to support compliance with the water use efficiency targets established under Senate Bill X7-7.

For retail water suppliers, the number of required DMMs was reduced to six standardized measures, along with an additional “other” category. Under the current requirements, agencies must provide a narrative description of the status of each DMM and explain how these measures contribute to achieving water efficiency goals; detailed quantitative data are no longer required.

The following sections summarize the City ’s current and planned efforts to implement the applicable Demand Management Measures.

9.1 Water Conservation Program Overview
DMMs help the City promote efficient water use, reduce water waste, and improve long -term water supply reliability. These measures are especially important for the City because supply reliability can be affected by Delta water quality, drought, climate change, and regional water supply conditions.

The City’s conservation program includes water waste prevention, metering, conservation pricing, public outreach, water loss control, and staff coordination. These efforts help reduce unnecessary potable water supply conditions.

9.2 Report Implementation
This section summarizes the City’s implementation of DMMs.

9.2.1 Implementation over the Past Five Years
The City conducts an ongoing water conservation program. The City has committed to implementing water conservation measures for all customer sectors. This section provides narrative descriptions addressing the nature and extent of each DMM implemented over the past five years, from 2021 through 2025. Table 9-1 presents a summary of water conservation measures over the past five years.

9-3

(vii)Other demand management measures that have a significant impact on water use as measured in gallons per capita per day, including innovative measures, if implemented.

In accordance with Urban Water Management Plan requirements, this plan addresses the following six DMMs:
• Water waste prevention ordinances
• Metering
• Conservation-oriented pricing
• Public education and outreach
• Programs to assess and manage distribution system real losses • Water conservation program coordination and staffing support

In addition, the City is required to describe any other DMMs that have been implemented and have had a significant effect on water use within the service area.

This section describes both the DMMs currently in place and those planned for future implementation.

For each DMM, the discussion includes a description of the existing program, an overview of implementation activities during the previous five-year period, and a summary of planned future actions.

9.3.1 Water-Waste Prevention Ordinances

The City has adopted a water waste prohibition ordinance included in its Municipal Code, Section 6-5.10.

The water waste ordinance is:

§ 6-5.10 WASTE OF WATER.

No person shall misuse or waste water. Any person misusing or wasting water shall be guilty of an infraction. The term MISUSE or WASTE shall mean the use of water which, to a reasonable person, is clearly in excess of the need or intended purpose. MISUSE o r WASTE may also mean the use of water in excess of quantity standards imposed during any water shortage emergency declared by the City Council.

In the event of any misuse or waste of water, in addition to criminal prosecution, the Finance Department may install flow restrictors at the premises where misus e or waste has occurred, following procedures established for such installation, which shall include at least one warning notice to the consumer prior to such installation. ('66 Code, § 6-5.10) (Ord. 76-A, passed 12-17-23; Am. Ord. 817-C-S, passed 7-11-91)

In addition, Section 6-10.05 of the City’s Municipal Code defines excessive use of water:

§ 6-10.05 EXCESSIVE USE OF WATER.

By resolution, the City Council may determine whether certain consumption amounts are excessive and beyond an established allocation and thus impose a penalty for such consumption as a violation of the law. (Ord. 2026-C-S, passed 5-26-09; Am. Ord. 2102-C-S, passed 5-12-15)

Most of the City’s cases of water wasting involve irrigation. The City requires all violators to take advantage of CCWD’s water conservation programs and assistance (Section 9. 3.7). The City’s Code Enforcement and Public Works staff carry out enforcement through courtesy notices, abatement letters, and citations for water waste violations. From 20 21 through 2025, the City issued no citations for water wasting violations.

August 2026

9-4

The implementation of the DMM is ongoing. Any violation of the Ordinance may result in water being turned off and remaining off until the party in violation can comply with the provisions. A customer will pay a fee with each shut-off. The City expects this implementation will help it achieve its water use targets by minimizing the nonessential uses of water so that water is available primarily for human consumption, sanitation, and fire protection.

9.3.2 Metering
Legal Requirements:

CWC Section 526:
(a) Notwithstanding any other provisions of law, an urban water supplier that, on or after January 1, 2004, receives water from the federal Central Valley Project under a water service contract or subcontract... shall do both of the following:
(1) On or before January 1, 2013, install water meters on all service connections to residential and nonagricultural commercial buildings... located within its service area.

Water Code section 527
(a) An urban water supplier that is not subject to Section 526 shall do both the following:
(1) Install water meters on all municipal and industrial service connections located within its service area on or before January 1, 2025.

The City is fully metered and requires meters for all new connections and bill customers according to volume-of-use. The City has no unmetered accounts and utilizes meters for internal use within parks and landscape irrigation.

9.3.3 Conservation Pricing
The City completed a comprehensive Water and Sewer Rate and Capacity Study in 2015 [10]. The rate study aims to ensure that water and wastewater rates produce enough revenue in order to meet operational and maintenance costs, fund improvements, and establish and maintain the adequacy of financial reserves.

City consumers are charged a monthly fixed service fee based upon their meter size and customer classification. The City’s residential water rate structure includes a monthly meter service charge and quantity charges for actual metered residential water use. The residential quantity charges are organized by elevation zone; higher rates are applied to higher elevatio n zones to account for additional pumping costs. This rate structure was adopted in 2015 and has been the City’s method for pricing during the 2021 through 2025 reporting period. Refer to Appendix H for the City’s water and sewer rate study.

9.3.4 Public Education and Outreach
Public information is an ongoing component of the City’s water conservation program. Activities incorporated in this program include:

• Bill inserts
• City website postings
• Brochures
• Participation in media events

2025 Urban Water Management Plan
August 2026

• Speaker’s bureau

9.3.5 Programs to Assess and Manage Distribution System Real Loss The City prepares annual water loss audits to evaluate distribution system water loss and identify opportunities to improve system efficiency . These audits help track real losses, apparent losses, data quality, and progress toward State water loss performance requirements. In addition, the City has an ongoing water main replacement program.

9.3.6 Water Conservation Program Coordination and Staffing Support The City has an Environmental Resources Coordinator focused on water conservation. The Environmental Resources Coordinator is an ongoing component of the City’s water conservation program. The Environmental Resources Coordinator is responsible for implementing and monitoring the City’s water conservation activities. Since July 2000 the City has maintained this position. The Environmental Resources Coordinator is a full-time staff position who devotes approximately one third of available time to water conservation. Regional conservation work is done through a partnership with CCWD. The City assigns no additional staff to conservation efforts; however, meter readers and other field workers do some leak checking and initial outreach and customer service representatives often provide conservation and leak detection advice to customers.

The implementation of this DMM should help the City achieve its water use targets by making water conservation and implementation of the City’s water conservation program a priority. The City cannot quantify water savings from this DMM directly. The City evaluates effectiveness of this DMM through the success of the City’s water conservation program.

9.3.7 Other Demand Management Measures
In addition to the six DMMs described above, City water customers can take advantage of conservation programs offered by CCWD including, but not limited to [8]:

• Residential:
o Water Wise House Calls- free in-person visit from a Water Conservation Technician o Free Water Conservation Devices
