After approving the expenditure of a little over $500,000 for the traffic calming devices on Sycamore Drive on Aug. 25, under Item 5.P. as part of the Consent Calendar for Tuesday’s meeting on Sept. 22, 2026, the Council approved on a 4-0 vote awarding the construction agreement to Consolidated Engineering, Inc. in the amount of $168,495 with a contingency of $30,000 for a total contract amount of $198,495 for the Neighborhood Traffic Calming Project.

It consists of the installation of speed hump systems, signage and thermoplastic striping. There will be a total of eight speed hump systems constructed on the following streets:

• Sunset Drive between Diablo and Beasley Avenues;
• E. Tregallas Road between Center Lane and Garrow Drive;
• Wildflower Drive between Larkspur Drive and Lupine Court;
• W. Madill Street between D and G Streets;
• D Street between the Railroad and Texas Street;
• East 19th Street between Acacia and Deodar Avenues;
• Sunset Lane between Northridge and Daphne Courts; and
• Candlewood Way between Arroyo and Stagecoach Ways.

According to the City staff report, funding for the project will be from the FY 25/26 Capital Improvement Budget which has a balance of $292,292 carried over into the FY 26/27 budget of $250,000 for a total of $542,292 from Measure J Funds. Following procurement of the contract and an estimated 10% of $16,850 for construction engineering, management, inspection, testing and contract administration, that will leave an estimated fund balance of $326,947.

Plus, discuss downtown security services, vote on emergency fuel purchase, more traffic calming devices, increasing investigative services contract, more water park repairs & improvements, and report on state and federal funds for housing and homeless

Still nothing on agenda about El Campanil Theatre although escrow closes Sept. 29th

By Allen D. Payton

During their regular meeting Tuesday, Sept. 22, 2026, the Antioch City Council has a full agenda and will vote on reestablishing the Economic Development Department, with one staff member and either a director or combined assistant city manager dual role,emergency fuel purchase, increasing investigative services contract for the Police Department by $250,000,almost $200,000 for more traffic calming devices and $141,000 for more improvements to the water park. They will also discuss restoring private security services in downtown Rivertown and the annual report on use of state and federal funds for housing and homeless services. Finally, the Council will vote on approving a Tentative Agreement with the Confidential Unit of City employees for a one-year 3% COLA increase.

That will follow a Closed Session at 6:00 p.m. during which the Council will meet to discuss the contracts with representatives of three employee organizations: Antioch Public Employees’ Association, Treatment Plant Employees’ Association and Antioch Police Sworn Management Association.

Reestablishing Economic Development Department, Director, Staff or Dual Assistant City Manager Role, Possible Commission

Under Item 7 the Council will vote on reestablishing a standalone Economic Development Department separate from Community Development, with funding for an Economic Development Director position with an amended salary range, an Economic Development Specialist, and assigning a budget; or directing staff to revise the existing Assistant City Manager job description whose primary role would be to focus on economic development in an 80/20 scope of work structure.

As previously reported and according to the City staff report, “Per the City Council’s direction from the August 31, 2026, Study Session, below are the options for discussion.

• A standalone Economic Development Department;

• An Economic Development Director responsible for oversight and implementation of the Economic Development Strategic Plan or amending the Assistant City Manager to an 80/20 dual role;

• Status of Economic Development Commission (EDC); and

• Providing a substantial budget to the Economic Development Department for programming and successful operations.

“Under the proposed 80/20 structure, the City Manager Department would gain dedicated Assistant City Manager capacity for executive initiatives, Council priorities, interdepartmental coordination, and organizational problem-solving, while retaining responsibility for matters that cannot be delegated. This creates a tradeoff between dedicated departmental oversight and unrestricted Assistant City Manager capacity.”

In addition, Mayor Ron Bernal suggested a salary range “something similar to the current Community and Economic Development Director of  $14,800 to $18,000.”

Also, as previously reported, the two departments were combined last year and has had an acting director since March 3rd, after a the new director was hired in October but left effective that day. The Economic Development Department hasn’t had a separate director since Kwame Reed was promoted to Assistant City Manager on Jan. 23, 2025. He, too, has since left the City for a job with the County.

While the Commission was never officially dissolved, during their meeting on April 9, 2024, the City Council voted unanimously to dissolve their own Restructuring of the Economic Development Commission Ad Hoc Committee. According to the meeting minutes, District 1 “Councilmember Tamisha Torres-Walker explained that the committee’s purpose was to restructure the EDC to improve functionality,” but “expressed her support for dissolving the existing Ad Hoc Committee.”

During that council meeting, then-District 3 Councilwoman Lori Ogorchock asked that the vacancies on the Commission be filled to no avail.

According to Tim McCall, the Commission’s former chairman, then-mayor “Lamar (Hernandez-Thorpe) refused to fill vacancies until they didn’t have a quorum anymore. People started quitting because they could see their volunteer work was going to waste and they had better uses for their time. I asked Lamar to fill the vacancies, but he didn’t.”

Downtown Security Services

Under Item 6, on the agenda, the Council will discuss downtown security services for City owned parking lots, property and public areas, and provide direction to staff on whether to initiate a competitive Request for Proposals (RFP) process for private security services in the Rivertown/Downtown area.

It follows the meetings held with and incorporates feedback received from downtown business owners and community members regarding hours of operation, patrol locations, scope of services and other identified needs.

Emergency Fuel Purchase Up to $500,000

Under Item 8, the Council will vote on purchasing fuel on an emergency basis through December 31, 2026, in an amount not to exceed $500,000, including applicable taxes, fees, delivery charges, and other associated costs,

to cover both the payment of outstanding fuel invoices accrued from July 1, 2026, through August 31, 2026, in the amount of $178,042.33 and the purchase of fuel necessary to maintain City operations until December 31, 2026, while City staff continue efforts to secure a new service provider for a long-term fuel supply agreement.

On April 28, 2026, the City Council approved a cooperative purchase agreement with Hunt and Sons for the purchase and delivery of unleaded and renewable diesel fuel for City operations. Hunt and Sons have not been able to meet the City’s insurance requirements and are therefore not able to perform this service under the terms of the agreement.

Since July 1, 2026, the City has continued receiving fuel deliveries from Hunt and Sons while staff, under consultation with the City Attorney’s Office, worked with the vendor to resolve the insurance requirements. The outstanding invoices will continue to accrue twice weekly as future fuel deliveries are made.

Annual Report on Use of State and Federal Housing and Homeless Funds

Under Item 9 the Council will receive public comments and vote on approving the Fiscal Year 2025–26 Consolidated Annual Performance and Evaluation Report (CAPER) for submission to the U.S. Department of Housing and Urban Development.

According to the City staff report, “The CAPER details the individual goals and achievements of funded agencies during the first year (FY 2025-26) of the 2025-30 Consolidated Plan. Most agencies exceeded their goals. Below is a summary of the Priority Goals and Annual Strategies that received funding in FY 2025-26. Funding sources below are identified by their stated abbreviation for funds committed and expended:

• Community Development Block Grant (CDBG) funding from the federal Department of Housing and Urban Development;

• Housing Successor (HS) funding authorized by the State for expenditure on affordable housing and homeless services; and

• Permanent Local Housing Allocation (PLHA) funding from the State for expenditure on affordable housing and homeless services.

A total of $1,701,909.45 was spent on the various programs and a balance of $144,428.20 in Habitat for Humanity Homeowner Housing Rehabilitation funds was carried over to and will be expended in FY26-27.

Breakdown of Residents Served

According to the FY 2025-26 Summary, “Funding from the City of Antioch Community Grants Program served a total of 6,497 Antioch residents during the past year for 148% of the cumulative goal of 4,398. Of the total Antioch residents served by all programs:

• 68.8% had household incomes of 30% or less AMI (Average Median Income);

• 28.7% had incomes of 50% to 31% AMI; and

• 2.5 had incomes of 80% to 51% AMI.

The demographic breakdown of all served against the demographics of the City of Antioch is provided in the chart above.

The report also states, “Overall, community-service activities exceeded the cumulative annual service goal, with most participating agencies meeting or exceeding their individual goals. Several affordable-housing activities remain in progress or below their annual production goals and will require continued monitoring, financial reconciliation, and follow-up during FY 2026–27.”

Increasing Investigative Services Contract for Police Department to Comply with DOJ, Allen Agreements

Under Item 10, the Council will consider approving Amendment No. 2 to the contract with Chaplin and Hill Investigative Services, increasing the contract amount by $250,000 for continued investigative services “required pursuant to the USDOJ MOU, the Allen Agreement, and applicable City policies and procedures,” according to the City staff report.

Also, according to City staff, “To maintain public confidence and uphold the integrity of internal investigations, the Antioch Police Department must ensure that its process for handling allegations of misconduct is impartial and consistent with applicable federal requirements. Engaging independent, external professional investigators provides an objective means of conducting investigations involving allegations of misconduct and other matters requiring an independent review.

“This approach is consistent with national law enforcement best practices and standards. The International Association of Chiefs of Police (IACP)…recommends the use of external investigators to promote fairness and impartiality in law enforcement investigations.”

City Employee Confidential Unit One-Year 3% COLA

Under Item 11, the Council will vote on approving a Tentative Agreement with the Confidential Unit of City employees which includes a one-year 3% Cost of Living Adjustment (COLA) and benefits for FY2026/27 at a cost of $123,000 with $103,000 from the General Fund. The Confidential Unit includes a variety of staff positions: the Deputy City Clerk, Account Specialists, Analysts, Assistants, Coordinators, Specialists and Technicians. The 26 employees in the Unit have been working without a contract since September 30, 2025. See City’s Master Salary Schedule.

CONSENT CALENDAR

More Traffic Calming Devices

After approving the expenditure of a little over $500,000 for the traffic calming devices on Sycamore Drive on Aug. 25, under Item 5.P. on the Consent Calendar, the Council will consider awarding the construction agreement to Consolidated Engineering, Inc. in the amount of $168,495 with a contingency of $30,000 for a total contract amount of $198,495 for the Neighborhood Traffic Calming Project.

It consists of the installation of speed hump systems, signage and thermoplastic striping. There will be a total of eight speed hump systems constructed on the following streets:

• Sunset Drive between Diablo and Beasley Avenues;

According to the City staff report, funding for the project will be from the FY 25/26 Capital Improvement Budget which has a balance of $292,292 carried over into the FY 26/27 budget of $250,000 for a total of $542,292 from Measure J Funds. Following procurement of the contract and an estimated 10% of $16,850 for construction engineering, management, inspection, testing and contract administration, that will leave an estimated fund balance of $326,947.

More Water Park Repairs & Improvements

Under Item 5.Q. the Council will consider approving an amendment to the construction agreement with Top Line Engineers, Inc. in the amount of $78,232.98, for a total contract amount of $276,732.98 for Prewett Water Park Concrete Improvements 2026 Project; and under Item 5.R. they will vote on approving a second amendment to the construction agreement with Adams Pool Solutions in the amount of $63,034, for a total contract amount of $855,632 for the Prewett Water Park Pool Resurfacing Project; and approving a budget amendment to the Fiscal Year 2026/2027 Capital Improvement and Operating Budgets utilizing General Funds for the project by $75,000.

Allocate & Reallocate State Violence Intervention & Prevention Grant Funds

Under Item 5.S, on the Consent Calendar, the Council will vote on approving a budget amendment to appropriate and reappropriate California Violence Intervention and Prevention (CalVIP) Cohort 5 Grant funds across Fiscal Years 2025–26 through 2028–29, consistent with the approved grant award and anticipated expenditure schedule.

According to the City staff report, “On March 10, 2026, the City Council authorized acceptance of $2,066,775 in CalVIP Cohort 5 funding administered by BSCC. At that time, Council appropriated $112,000 for anticipated Fiscal Year 2025–26 expenditures and directed that the remaining grant balance be incorporated into subsequent fiscal-year budgets consistent with the grant term and approved spending plan.

“CalVIP is a competitive State grant program supporting jurisdictions disproportionately impacted by violent crime through evidence-based violence interruption, prevention, and intervention strategies. The City’s Cohort 5 award continues and expands upon violence intervention infrastructure established through prior CalVIP funding beginning in 2022.

“CalVIP Cohort 5 supports the City’s continued violence intervention and prevention activities, including personnel dedicated to program administration, violence intervention and outreach; community-based services and partnerships; participant supports; evaluation and performance measurement; and other activities authorized under the approved grant agreement.

“Because the…Cohort 5 grant extends across multiple City fiscal years, expenditure authority must be appropriately budgeted within each fiscal year in which grant-funded costs are anticipated.

The proposed budget amendment…establishes and adjusts appropriations across Fiscal Years 2025–26 through 2028–29 to align the City’s financial budget with the anticipated timing of…Cohort 5 expenditures.

Hold 2027-28 General Fund Budget Study Session to address projected $15.2 million deficit

Closed Session on employee group contracts, 9 potential lawsuits

By Allen D. Payton

During their meeting on Tuesday, August 25, 2026, the Antioch City Council will vote on a one-year MOU with the Antioch Police Officers Association at a cost of $661,000, purchasing AI-assisted automated license plate recognition, in-car camera and integrated public safety technology systems for the  police department at a cost of $662,000, additional handheld two-way radios for APD emergency communications at a cost of $300,000, spending $500,000 on Sycamore Drive Traffic Calming Improvements, expanding the contract for the monitoring consultant required by the USDOJ’s Allen Settlement Agreement at a cost of $150,000 and appoint one member to the Sales Tax Citizens’ Oversight Committee.

The Council will also receive the 2025 Annual Military Equipment Report from the police department and an Investment Performance Review presented by the City’s advisors, FM Asset Management, and hold a public hearing on the 2025 Urban Water Management Plan and Water Shortage Contingency Plan.

Closed Session

Prior to the Regular Meeting that begins at 7:00 p.m., the Council will hold a Closed Session at 3:30 PM for a Conference with Labor Negotiators to discuss contracts for the Antioch Public Works Employee Association (APWEA), Antioch Police Sworn Management Association (APSMA), Confidential Unit, and Management Unit and a Conference with Legal Counsel for “significant exposure to litigation” as the City faces nine potential cases.

2027-28 General Fund Budget Study Session

Then at 5:30 p.m. the Council will hold a Special Meeting Budget Study Session to discuss the Fiscal Year 2027-28 General Fund Budget Development. Acting City Manager Ana Cortez and Finance Director Dawn Merchant say the City’s consultant is projecting a decrease in sales tax revenue of $700,000 to $1.68 million for this Fiscal Year.

According to their report for Item SM-1 on the agenda, “even with the extensive work that was done (on the FY 2026-27 budget), 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.

“Detrimental decreases to our sales tax budgets from the latest projections from our consultant…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.”

In addition, the “3% COLA recently approved for the APOA bargaining unit ($745,667 FY28 impact”…and “reduction of $1.2M in projected contribution to HomeKey+ project with City Council rejection of the grant…as a result…the projected 2027-28 deficit spending has increased slightly to $15.2M.”

3% Pay Raise for Antioch Police Officers

Under Item 6.I. on the Consent Calendar, the Council will vote on the Memorandum of Understanding (MOU) between the City of Antioch and the Antioch Police Officers’ Association that will include a 3% Cost of Living Adjustment (COLA) for Fiscal Year 2026-27 at a cost of $661,430 and other matters.

At their meeting on July 28, 2026, the council approved a tentative agreement. Staff then prepared the MOU to replace the agreement and require another vote by the council.

As reported, the previous Tentative Agreement covered the period of Sept. 1, 2021 – Aug. 31, 2025.

In addition to the 3% COLA, the Tentative Agreement includes the following:

• Increase to four floating holidays in a calendar year.
• Travel meal reimbursement increase to $25.00 for breakfast, lunch or dinner.
• Lateral Police Officer and Dispatcher new hire vacation credit of one week upon employment.

Plus, increases to the uniform allowance, adjustments to benefits, retirement and vacation, sick leave and bereavement leave language defined and/or updated, as well as updates to the department’s grievance procedure.

Purchase Police Department AI-Assisted Integrated Technology Systems

Under agenda Item 9, the Council will consider the purchase of automated license plate recognition (ALPR), in-car camera and integrated public safety technology systems. The vote will be to approve a sole source agreement with Axon Enterprise, Inc. for 55 fixed automated license plate recognition (ALPR) locations using Axon Outpost, six additional Axon Fleet 3 in-car video and mobile ALPR systems, and 120 Axon AI Assistant licenses for the Police Department, for a 49-month term beginning October 1, 2026, in an amount not to exceed $661,687.54.

Funding for FY 2026-27 has been identified within the existing Police Department General Fund budget; payments in future fiscal years will remain subject to the annual budget process.

ALPR helps officers and investigators identify vehicles associated with shootings, robberies, burglaries, stolen vehicles, hit-and-run collisions, organized theft, missing persons, illegal sideshows, and other serious incidents.

According to the City staff report, “the Department currently operates fixed ALPR cameras through Motorola and Flock. Motorola is decommissioning its ALPR platform, and the proposed purchase would replace and consolidate the two fixed systems into a single Axon network while expanding fixed coverage. APD already uses Axon Body 4 cameras, Axon Fleet in-car cameras, and Axon Evidence as its primary digital evidence environment.”

Purchase 30 More Police Dep’t Handheld Two-Way Radios for Emergency Communications

Under Item 6.G. of the Consent Calendar the Council will consider purchasing additional handheld two-way radios for the police department’s emergency communications. The vote will be to adopt a resolution authorizing the sole source purchase of 30 Motorola APX N70 handheld two-way 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.

Public Hearing on 2025 Urban Water Management Plan & Water Shortage Contingency Plan

During the regular meeting the council will hold a Public Hearing on the 2025 Urban Water Management Plan and Water Shortage Contingency Plan. According to the City staff report for Item 7 on the agenda, he 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 an 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 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).

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.

Sycamore Drive Traffic Calming Improvements

Under Item 6.H. on the Consent Calendar, the council will consider awarding a construction agreement to the lowest, responsive, and responsible bidder, Martinez-based Cowan & Thompson Construction, Inc. in the amount of $488,511.94, with a $25,000 contingency for a total contract amount of $513,511.94 for the Sycamore Drive Traffic Calming Improvements Project.

According to the City staff report, the FY 2026/27 Capital Improvement Budget includes $425,000 of Gas Tax funding for the project. Approval will increase the allocation by $89,000. The projected June 30th balance of Gas Tax funds with this amendment is projected to be $1,014,298.

The devices will be placed in eight segments along the street and will include signs and raised traffic separator curb guidance systems with quick release delineator bases.

See Project plans for all planned traffic calming device locations on Sycamore Drive.

Sales Tax Citizens’ Oversight Committee Appointment

Under agenda Item 8 the Council will vote on appoint Dr, Loretta Ezeife to the Sales Tax Citizens’ Oversight Committee for a full-term vacancy expiring March 2030. According to her application, she has lived in Antioch since 2008 and works as the Accounting Officer for the University of the Pacific in Stockton, “with over 25 years of experience overseeing financial operations across private industry, public agencies, and higher education.”

Meeting Details

The meeting will be held in the Council Chambers at City Hall, 200 H Street, in historic, downtown Rivertown and can be viewed via livestream on the City’s website or on Comcast cable TV channel 24 or AT&T U-verse channel 99.

Public Works Director Scott Buenting and Water Treatment Plant Superintendent Marcus Woodland were presented last month with an Engineering Excellence Award from the American Council of Engineering Companies of California (ACEC). Carollo Engineers of Walnut Creek submitted the Antioch project for consideration which received a ACEC California Merit Award.

The ACEC California’s annual Engineering Excellence Awards competition recognizes outstanding achievements in engineering and land surveying projects completed by California firms. Entries are accepted into one of 12 project categories: studies, research and consulting engineering services; building/technology systems; structural systems; surveying and mapping technology; environmental; waste and storm water; water resources; transportation; special projects; small projects; energy; and industrial and manufacturing processes and facilities. 

Projects were recognized for demonstrating an exceptional degree of innovation, complexity, achievement, and value. Twenty projects earned the prestigious Honor Award distinction, twenty-seven were recognized with Merit Awards, and fifteen Commendation Awards were granted.

“We are proud to recognize these ACEC California firms for delivering an exceptional degree of value and technical excellence to our communities,” said Tyler Munzing, Executive Director of ACEC California. “Quality infrastructure—from dependable drinking water to safe, efficient roadways and structurally sound public spaces—is essential to our state’s success. These award-winning projects showcase how our engineering and land surveying firms are passionately building a more resilient and connected California.”

The awards were announced at the Engineering Excellence Awards Banquet on February 19, 2026. The annual celebration is also a fundraiser for the ACEC California Scholarship Foundation 501(c)3, which provides scholarship awards to graduate and undergraduate students who are recognized for their notable and outstanding academic achievements.

These recognitions highlight the expertise and dedication of the team working to deliver safe, reliable water for our community.
