LORI BALLATI thanked the City Council, Recreation Department, and everyone involved in supporting the construction of the new pickleball courts in Los Banos. She said the courts have been very well received and are heavily used in the mornings and evenings. She noted that teenagers, commuters, working residents, and new players have been using the courts and playing into the evening. Ms. Ballati invited the Council and community to visit the courts. BRAD MCCRAY spoke in support of the new pickleball courts, noting that he regularly sees new players learning the sport and participating in lessons. He said the increased activity and number of new players has been one of the most positive aspects of the new courts. HENRY PENAMONTE thanked the City for the new courts and said he was surprised by the number of young people and new players using them in the evenings. As someone who commutes between Los Banos and San Jose, he said evening play is particularly important to him and expressed excitement about the planned installation of lights. LANDY SALVA also thanked the City for the courts and said they have encouraged her to play more. As a teacher who recently returned to work, she said she is primarily able to play in the evenings and appreciates seeing young people using the courts. She said lighting would be greatly appreciated as the days become shorter.
Ms. Ballati reiterated that the courts are being used extensively and encouraged Council Members to visit and see the activity firsthand. ERASMO VIVEROS, Los Banos, thanked the Public Works Department, City Manager, and Traffic Safety Committee for their quick response regarding the intersection of 4th and J Streets. He said the stop signs were installed shortly after the Traffic Safety Committee reviewed the issue and that the signs have helped slow traffic. Mr. Viveros said that, before the signs were installed, he frequently heard drivers arguing and observed vehicles traveling at high speeds and racing through the area. He thanked the City for listening to downtown residents and taking swift action to improve safety at the intersection. City Clerk Mallonee read the following items: Email from ANDREW AYALA concerns about speeding vehicles and motorcycles in the Vineyard neighborhood, particularly on Cabernet Street.

No one else came forward to speak and the public forum was closed.
Mayor Amabile thanked residents for participating in the public forum and submitting correspondence, noting that public input helps the City Council and staff understand neighborhood concerns.

CONSIDERATION OF ADOPTION OF CITY COUNCIL RESOLUTION NO. 7147 – RATIFYING THE CITY MANAGER’S APPROVAL OF THE EMPLOYMENT
AGREEMENT BETWEEN THE CITY OF LOS BANOS AND ROBERT LOMELI AS EMPLOYEE FOR THE POSITION OF ASSISTANT CITY ATTORNEY. City Manager Than presented the staff report, explaining that the Assistant City Attorney position was included in the adopted budget and that, as a management position, an employment agreement was required. He introduced Robert “Rob” Lomeli and highlighted his more than 20 years of public-sector experience in municipal law, labor law, public safety, and water issues, as well as his prior experience as a deputy sheriff. Mr. Than recommended ratification of the employment agreement, effective August 24, 2026. The agreement provides an annual salary of $234,996, management employee benefits, 120 hours of vacation leave, 96 hours of sick leave, 96 hours of administrative leave, paid holidays, and a $500 monthly vehicle allowance.
Mayor Amabile invited the public to comment. ERASMO VIVEROS questioned the cost savings associated with bringing legal services in-house compared to the City’s prior legal expenses. He also asked how the position would be integrated throughout the City and what the City would receive in return for the additional position. No one else came forward to speak.
Mayor Amabile discussed the City’s prior legal expenses, noting that the City had spent approximately $1 million annually on attorney fees. City Manager Than explained that the City had historically spent approximately $1 million to $1.2 million annually on outside legal services, including firms such as BBK and LCW. He noted that the high hourly cost of outside counsel often limited departments’ ability to use legal services because those expenses impacted department budgets. Mr. Than stated that having an in-house legal team allows the City to be proactive rather than reactive and provides readily available legal guidance on matters such as construction claims, employee protections, workers’ compensation, and public safety laws, including POBAR and FBOR. He said the position was expected to be essentially a wash, with potential savings, and noted that approximately $500,000 had been available in the budget due to reduced reliance on outside professional services. Mr. Than also emphasized succession planning and continuity within the City Attorney’s Office. He noted that matters such as Public Records Act requests, which were previously handled by consultants, are now being handled inhouse. He added that department heads have experienced a significant improvement in responsiveness with legal services available internally. City Attorney Lerner stated that prior legal service bills did not necessarily reflect the City’s actual legal needs because legal services were often an area where departments attempted to limit expenditures.
She said it is better to address legal issues proactively and noted that additional work, including updating the Municipal Code and ensuring compliance with state law, is needed.
Mayor Amabile spoke in support of having an attorney dedicated to the City who is familiar with its operations and can identify potential legal issues before they become problems. 16 She noted the challenges of relying on outside attorneys and the benefit of having legal counsel available to staff and the community. Council Member Lewis stated that the position would allow the City to stay ahead of legal issues and prepare for future laws, updates, and compliance requirements. She called the position worthwhile and beneficial to the City’s future. Council Member Chavez also supported the position, stating that having an in-house attorney allows the City to seek legal guidance without the additional concern of outside legal fees and helps the City remain proactive rather than reactive.
Motion by Lewis, seconded by Chavez to adopt City Council Resolution No. 7147 – Ratifying the City Manager’s Approval of the Employment Agreement Between the City of Los Banos and Robert Lomeli as Employee for the Position of Assistant City Attorney.
The motion carried by the following roll call vote: AYES: Chavez, Lewis, LLamas, Perez, Mayor Amabile; NOES: None; ABSENT: None.
Mr. Lomeli thanked the City Council for the opportunity and expressed his appreciation for the opportunity to join the City. He said he looked forward to working with the Council and staff and helping the City continue moving forward.
CONSIDERATION OF ADOPTION OF CITY COUNCIL RESOLUTION NO. 7148 –
APPROVING A MEMORANDUM OF UNDERSTANDING BETWEEN THE CITY OF
LOS BANOS AND QUIRING GENERAL, LLC FOR PRECONSTRUCTION SERVICES FOR FIRE STATION NO. 4 AND AUTHORIZING THE CITY MANAGER TO EXECUTE THE AGREEMENT. Public Works Director Via presented the staff report, explaining that the City is working with the design-build team to further evaluate the project scope and bring the project within the established $13 million budget. The pre-construction work will include reviewing the existing design documents, developing schematic designs, refining the project scope, estimating costs, and identifying potential areas for cost savings before entering into a final design-build agreement. City Manager Than spoke regarding the project and clarified that the $283,125 cost for the pre-construction services is included within the $13 million project budget. He explained that the City is evaluating the option of housing the Fire Station and Emergency Operations Center under one roof rather than constructing two separate buildings, which could provide cost savings while maintaining the intended functions of the project.
Mayor Amabile invited the public to come forward to speak, and no one came forward.
Council Member LLamas asked about the parking and site layout. City Manager Than explained that the facilities would have separate functions, but could share certain areas such as a lobby. He noted that the design process would further evaluate entrances, parking, physical separation, and other site details, while identifying additional opportunities to reduce costs.
Motion by Lewis, seconded by Chavez to adopt City Council Resolution No. 7148 – Approving a Memorandum of Understanding Between the City of Los Banos and Quiring General, LLC for Preconstruction Services for Fire Station No. 4 and Authorizing the City 17 Manager to Execute the Agreement. The motion carried by the following roll call vote:
AYES: Chavez, Lewis, LLamas, Perez, Mayor Amabile; NOES: None; ABSENT: None.
CONSIDERATION OF ADOPTION OF CITY COUNCIL RESOLUTION NO. 7149 –
APPROVING A MEMORANDUM OF UNDERSTANDING BETWEEN THE CITY OF
LOS BANOS AND THE COUNTY OF MERCED FOR REPAVING OF PIONEER ROAD AND AUTHORIZING THE CITY MANAGER TO EXECUTE THE AGREEMENT. Public Works Director Via presented the staff report, explaining that the County had recently completed its repaving project from Volta Road to the City limits on Pioneer Road. The City requested that the County extend the paving to the limits of the City’s new intersection at Ortigalita Road and Pioneer Road, creating a continuous newly paved roadway. Mr.
Via stated that the project covers approximately 2,750 linear feet and that, because the County’s contractor was already mobilized, the City’s cost for the additional paving was approximately $250,000. He explained that the City had originally considered completing the work as part of its own project but was unable to do so because of federal funding requirements and the work being outside the City limits.
Mayor Amabile invited the public to comment, and no one came forward. He noted that the project demonstrated the benefits of working cooperatively with the County and asked about the estimated savings. Mr. Via estimated the City saved approximately $50,000 in project costs, not including staff time associated with preparing bid documents and administering the bidding process. He noted that the savings could potentially exceed $100,000 compared to completing the project independently.
Council Member Chavez thanked Merced County Road Commissioner Nathan Bray for working with the City and noted the importance of improving roads in and around Los Banos. Mr. Via provided an update that the first phase of the City’s 2026 roadway rehabilitation projects in the Snow Goose area had been completed, with the I Street portion remaining.
Motion by Chavez, seconded by Perez to adopt City Council Resolution No. 7149 – Approving a Memorandum of Understanding Between the City of Los Banos and the County of Merced for Repaving of Pioneer Road and Authorizing the City Manager to Execute the Agreement. The motion carried by the following roll call vote: AYES: Chavez, Lewis, LLamas, Perez, Mayor Amabile; NOES: None; ABSENT: None.
CONSIDERATION OF ADOPTION OF CITY COUNCIL RESOLUTION NO. 7150 –
APPROVING AN AMENDED AND RESTATED PROPERTY TAX SHARING
AGREEMENT BETWEEN THE CITY OF LOS BANOS AND THE COUNTY OF MERCED. City Manager Than presented the staff report, describing the agreement as another example of collaboration between the City and County. Mr. Than provided background on the existing agreement, originally adopted in 1997 and amended in 2016.
He explained that the agreement establishes how property tax revenues are shared between local agencies when properties are annexed or development occurs. He noted that the City’s adoption of the 2042 General Plan, which expanded the City’s sphere of influence and updated land-use planning, required the property tax sharing agreement to 18 be updated. Mr. Than stated that the City and County were able to reach an agreement on the proposed amendments in approximately six weeks, compared to approximately six months during the previous negotiations. He credited the collaboration of the City Council, Supervisor Silveira, County CEO Mark Hendrickson, and Assistant CEO David Marioni. He said the amended agreement formally recognizes the City’s 2042 General Plan and reflects the City’s anticipated growth and service areas.
Mayor Amabile invited the public to come forward to speak and no one came forward.
Motion by Chavez, seconded by Lewis to adopt City Council Resolution No. 7150 – Approving an Amended and Restated Property Tax Sharing Agreement Between the City of Los Banos and the County of Merced. The motion carried by the following roll call vote:
AYES: Chavez, Lewis, LLamas, Perez, Mayor Amabile; NOES: None; ABSENT: None.

He thanked Council Member Perez for her service and wished her well.
MARCUS CHAVEZ – DISTRICT 3: Welcomed the new hires and promoted employees and congratulated Mr. Lomeli on joining the City. He thanked Public Works staff for their ongoing landscaping and cleanup efforts. He requested a follow-up regarding pedestrian and traffic safety improvements near Pacheco High School, particularly the crosswalks, now that school was back in session. He also expressed concern regarding the deteriorating condition of State Route 152 through Los Banos and requested that the City work with Caltrans to explore interim patching or other repairs before the scheduled roadway improvements.
MICHAEL S. AMABILE – MAYOR: Reported Mayor Amabile reported on upcoming MCAG and LAFCO meetings, noting that MCAG would receive a Caltrans update and that he planned to raise the condition of State Route 152 and potential interim repairs. He also noted that LAFCO would consider several matters affecting Los Banos, including the City’s storm basin. He reported that the City continues to meet with County representatives regarding regional issues and projects. He discussed the City’s coordination with the County on roadway and drainage issues, noting that the upcoming winter could bring significantly more rainfall than normal. He emphasized the importance of proactively cleaning and maintaining waterways, including Los Banos Creek, to reduce the potential for flooding. He also shared an idea he observed while visiting Petaluma, where alleyways have names, and suggested that Los Banos could consider naming some of its alleyways. He discussed efforts to develop additional sister-city relationships.
He recalled the City’s existing relationship with Bahía de Kino, Mexico, and explained that the City had previously explored relationships with Italian, Basque, and Portuguese communities. He reported that a resident with family connections to Grementanova-area in Italy had contacted him about sending a letter to the mayor there, and he expressed interest in pursuing that relationship. He also said he was interested in identifying potential sister cities in the Azores and Basque region. He further discussed Los Banos’ historical connection with Breckenstein, Germany, noting its connection to Henry Miller. He recalled that the mayor of Breckenstein was unable to attend the dedication of the Henry Miller Plaza but visited Los Banos the following week. During the visit, the City learned that Henry Miller had provided financial support for public buildings in Breckenstein, including 21 its city buildings, courthouse, and museum. Mayor Amabile said these international relationships provide an opportunity to strengthen community connections and recognize Los Banos’ history.

TO: Mayor and City Council Members
FROM: William Via, Jr., Public Works Director
DATE: September 2, 2026
TYPE OF REPORT: Consent Agenda
SUBJECT: Notice of Completion for the Downtown Gateway Sign Installation Project ______________________________________________________________________ Recommendation:
Staff recommends that the City Council adopt a Resolution:
1. Accepting the Downtown Gateway Sign Installation Project as complete; and
2. Authorizing the filing of the Notice of Completion with the Merced County Recorder’s Office; and
3. Releasing applicable retention in accordance with the contract documents and California Public Contract Code, following the statutory 35-day period.
Background:
On April 17, 2024, the City Council authorized the City Manager to execute a contract with P&F Metals for the design, manufacture, construction, and installation of the Downtown Gateway Sign. The City utilized a Request for Proposals (RFP) process after prior bid proposals substantially exceeded the City's available budget for the project.
Following evaluation of the submitted proposals, P&F Metals was determined to be the only responsive proposer and was awarded the contract in the amount of $588,272.49.
The project included the design, fabrication, construction, and installation of the Downtown Gateway Sign and associated improvements. The work has now been completed in accordance with the approved plans, specifications, and contract requirements
23 ITEM 6C
Discussion:
City staff has inspected the completed work and determined that the project has been constructed in substantial conformance with the contract documents. All required work has been completed to the satisfaction of the City.
Pursuant to California Civil Code Section 9204 and related provisions, filing a Notice of Completion establishes the statutory period for the filing of any remaining claims associated with the project. Approval of the Notice of Completion is the final administrative step in closing out the construction contract.
Staff therefore recommends that the City Council accept the project as complete and authorize the filing of the Notice of Completion.
Environmental Analysis:
The project was previously reviewed in accordance with the California Environmental Quality Act (CEQA). Staff determined that the project was categorically exempt pursuant to CEQA Guidelines Section 15311 (Accessory Structures).
Fiscal Impact:
All project costs were funded through previously approved appropriations for the Downtown Gateway Sign Project. Acceptance of the project and filing of the Notice of Completion will have no additional impact on the City's General Fund. The contract amount approved by the City Council was $588,272.49.

DATE: September 2, 2026
TYPE OF REPORT: Consent Agenda
SUBJECT: Authorizing Award of Construction Contract to Hensley’s Paving and General Engineering, Inc. for the Alley Overlay Improvements Project _____________________________________________________________________ Recommendation:
That the City Council adopts the Resolution awarding the Alley Overlay Improvements project contract to Hensley’s Paving and General Engineering, Inc., authorizing the City Manager to execute the Construction Contract in the amount of $419,580.03, and authorizes the Public Works Director to administer the Construction Contract, including the contingency. Staff is requesting a 15% contingency of $62,937.00.
Background:
The City maintains a network of public alleys that provide access to residents, businesses, utilities, and public services. Over time, pavement in several alleys has deteriorated due to age, weathering, and regular vehicle use, resulting in surface cracking, potholing, and uneven pavement conditions. The Alley Overlay Improvements Project was developed to rehabilitate selected alley segments, improve pavement conditions, extend the useful life of the existing infrastructure, and support safe and reliable access within the community. This project will also slurry, crackseal, and restripe the 6th Street Parking lot at the northeast corner of 6th Street and Pacheco Blvd.
Discussion:
The major work consists of planning and repaving approximately 27,602 square feet of pavement using approximately 417 tons of asphalt concrete, furnishing and applying approximately 48 tons of Type II Slurry Seal, reconstructing approximately 1,460 lineal feet of valley gutter, applying pavement markings and signage, and other miscellaneous 29 ITEM 6D
appurtenant work in three alleyways within the Downtown Corridor of the City of Los Banos. The three alley locations are as follows:
• Chase Bank Alley, from 5th Street to 7th Street
• City Hall Alley, from 5th Street to 7th Street
• Bank of America Alley, from 5th Street to 7th Street
• Slurry Seal and Restriping of the parking lot at 6th Street and Pacheco Blvd.
Staff enlisted the services of Gouveia Engineering, Inc., to design the project. The project was released for advertisement on Wednesday, July 22, 2026. The bid opening was held on Wednesday, August 12, 2026. The Public Works Department, through the office of the City Clerk, received seven (7) bids from the following contractors:
Hensley’s Paving and General Eng, Inc Waterford, CA $419,580.03 United Pavement Maintenance Hughson, CA $462,275.57
Tom Mayo Construction, Inc. Stockton, CA $467,055.00
Tosted Asphalt, Inc. Madera, CA $473,636.60
Cal Valley Construction, Inc. Fresno, CA $493,749.50
Rolfe Construction, Inc. Atwater, CA $560,801.00
Arrow Drillers, Inc. Madera, CA $589,900.00
Staff reviewed each of the bid proposals for completeness. Hensley’s Paving and General Engineering, Inc. has provided the lowest responsive and responsible bid for the project.
Staff is recommending Hensley’s Paving and General Engineering, Inc. be awarded the contract for the construction of the Alley Overlay Improvements. Staff recommends a contingency of fifteen percent (15%) to allow for any unforeseen conflicts as we may encounter unmark or abandoned utilities that will need additional attention. The administration of this contract, including the 15% contingency, is to be performed by the Public Works Director.
A community informational meeting was held on Monday, August 24, 2026, to provide residents, business owners, and other interested stakeholders with an overview of the proposed Alley Overlay Improvements Project. City staff presented the project scope, identified the three alley locations, discussed the anticipated construction process, and provided an opportunity for attendees to ask questions and provide comments. The meeting also allowed staff to share information regarding construction access, potential traffic and parking impacts, and the City’s intent to coordinate with affected property owners and businesses prior to and during construction.
Environmental Analysis:
The proposed Alley Overlay Improvements Project has been reviewed pursuant to the California Environmental Quality Act (CEQA), the CEQA Guidelines, and the City of Los Banos Environmental Quality Guidelines. The project consists of pavement rehabilitation and overlay work within existing alley rights-of-way and will not add vehicle travel lanes, 30 increase roadway capacity, or otherwise expand the existing use. Therefore, the project is categorically exempt from CEQA pursuant to CEQA Guidelines Section 15301(c), Existing Facilities, which applies to the repair, maintenance, and minor alteration of existing highways, streets, sidewalks, gutters, and similar facilities involving negligible or no expansion of use. Staff have determined that no exception to the categorical exemption applies.
Fiscal Impact:
Funds for this project have been budgeted for in the Streets Fund account 100-431-210- 726 and the Community and Economic Development Fund account 100-419-100-726 in the 2026-2027 Fiscal Year budget.

3. Authorize the City Manager to execute the contract.
Background:
The Mercey Springs Waterline Improvements Project is intended to improve water system reliability and support fire protection along the Mercey Springs Road/State Route 165 corridor. The project was advertised for competitive bidding on July 22, 2026, with sealed bids due and publicly opened on August 13, 2026. The work includes installation of a new water transmission main and related improvements between Pioneer Road and State Route 152.
Discussion:
43 ITEM 6E
The major work consists of installing approximately 4,432 linear feet of 18-inch C-900 PVC water main, including tees, valves, appurtenances, and fire hydrants spaced approximately every 300 feet. The water main will be installed by open cut on the east side of, and parallel to, the northbound lane of State Route 165 between Pioneer Road and State Route 152, with fire hydrant laterals crossing both the northbound and southbound lanes.
The City received 10 bids. The bids were opened on August 13, 2026.
Bidders: Location Bid Amount
Katch Environmental, Inc. Fresno, CA $1,574,016.00
Agee Construction Corporation Clovis, CA $1,625,685.00
SW Construction, Inc. Bakersfield, CA $2,042,773.59

In addition to the base bid amount, staff recommends including a 15% contingency to address unforeseen conditions that may arise during construction.
The project is anticipated to begin in Fall 2026. The construction contract is anticipated to have a duration of ninety (90) working days.
CEQA:
The proposed action is exempt from the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15303, Class 3 – New Construction or Conversion of Small Structures, which includes water main, sewage, electrical, gas, and other utility extensions of reasonable length. The Mercey Springs Waterline Improvements Project consists of installing a new water transmission main and related water system appurtenances within and adjacent to existing roadway right-of-way to 44 improve water service reliability and fire protection. The project would not result in a significant expansion of use, and no unusual circumstances have been identified that would preclude use of the categorical exemption.
Fiscal Impact:
Funding for the Mercey Springs Waterline Improvements Project is included in the Fiscal Year 2026–2027 Budget in the Water Fund Account No. 501-561-100-739 ($1,106,595-70.26%) and Water-Restricted Account No.511-461-100-739 ($468,405-
29.74%). The construction contract with Katch Environmental, Inc. is $1,574,016.00.
Including a 15% construction contingency of $236,102.40, which brings the total construction amount to $1,810,118.40. An additional $189,881.60 is estimated for construction management, construction observation, and soils testing, bringing the total anticipated project cost to $2,000,000.00.
The project currently has an approved budget of $1,575,000.00 (with the same percentage split mentioned above). Based on the anticipated total project cost of $2,000,000.00, an additional appropriation of $425,000.00 is required to fully fund the project. Staff recommends increasing Fiscal Year 2026–2027 expenditures in Water Fund Account No. 501-561-100-739 by $298,605.00 and Water-Restricted Fund Account no. 511-461-100-739 by $126,395.00. Sufficient fund balance is available in both funds to support the requested appropriation.

56 Agenda Staff Report
TO: Mayor and City Council Members
FROM: William Via, Jr., Public Works Director
DATE: September 2, 2026
TYPE OF REPORT: Consent Agenda
SUBJECT: Rejecting all bids for the Ag Sports Pickleball Lights Project _____________________________________________________________________ Recommendation:
That the City Council adopts the Resolution rejecting all bids for the Ag Sports Complex Pickleball Lights Project.
Background:
In June 2026, Public Works released the Ag Sports Complex Pickleball Lights Project bid package for advertisement. On July 23, 2026 six (6) sealed bids were received and were officially opened by the office of the City Clerk. The bids received are included below.
Contractor Location Bid Amount
Sactown Contractors Corp Sacramento, CA $211,550.00*
Shane Brown Electric Woodland, CA $526,400.00
James Day Construction, Inc. Lower Lake, CA $500,722.05 New Century Construction & Consulting Inc. Turlock, CA $222,900.00 Nema Construction Albany, CA $465,460.00
Just Wright Construction Inc. Oakland, CA $346,316.00
*Amount corrected after bid tabulation
Discussion:
Following the bid opening, City staff conducted a review of the bid documents submitted by each bidder to determine responsiveness and compliance with the requirements of the 57 ITEM 6F
bid package. During this review, staff found that the three lowest bidders did not submit all required bid documents and/or complete all forms correctly and necessary to establish responsiveness, and could not be waived without compromising the integrity of the competitive bidding process, these bids were determined to be non-responsive and could not be considered for award.
After eliminating the non-responsive bids from consideration, the remaining responsive bids exceeded the Engineer's Cost Estimate and available project budget. In consultation with the City Attorney, the Public Works Director determined that it is in the City's best interest to reject all bids and re-advertise the project to ensure complete and responsive bid submissions.
Per section 3-16.07 of the municipal code, the City Council may reject any and all bids presented if the Public Works Director, prior to rejecting all bids, furnishes a written notice to an apparent low bidder, informing the bidder of the City’s intention to reject the bid at least two (2) business days prior to the hearing at which the City Council intends to reject the bid. On August 5, 2026, a notice of intent to reject all bids was provided to all bidders, all builder exchanges included in the original notification requesting bids, and posted on the City Website. All bids may be rejected whenever the agency determines that the cost is not reasonable, the cost exceeds the amount estimated, or is otherwise in the best interest of the agency. Per section 6.02B of the State Contracting Manual, there is no basis for protest if the awarding agency rejects all bids based on the best interest of the agency.
Fiscal Impact:
The project will go out to re-bid at a future time. Funds for this project have been programmed from account 250-454-220-726 in the 2026-2027 fiscal year (FY27) budget.

66 Agenda Staff Report
TO: Mayor Amabile & City Council Members
FROM: Brandon Dorenbush, Fire Chief
DATE: September 2, 2026
TYPE OF REPORT: Consent Agenda
SUBJECT: Approval of Cooperative Procurement Agreement with Winner Chevrolet/Elk Grove Auto Group for the Purchase of Three (3) Chevy Tahoe Fire Command Vehicles.
_____________________________________________________________________ Recommendation:
That the City Council approve the purchase of three (3) 2027 Chevy Tahoe 4x4 Command vehicles through the State of California Cooperative Purchasing Agreement from Winner Chevrolet/Elk Grove Auto Group, utilizing available funds designated for fire vehicle replacement in the Fiscal Year 2026-2027 adopted budget.
Discussion:
The Los Banos Fire Department has identified the need to replace two (2) vehicles that have reached the end of their useful service life and add one (1) additional command vehicle to the fleet. The vehicles being replaced include one (1) 2014 Ford F-150 4 x 4 and one (2018) Chevy 1500. These vehicles have experienced increased maintenance needs, reduced reliability, and are no longer suitable for continued frontline operations due to their overall condition and age.
The replacement vehicles will be assigned to support department operations. One (1) Chevy Tahoe will be assigned as the first out command unit to provide a reliable response on a daily basis, one (1) will replace the current Fire Marshal vehicle, and one (1) new administrative vehicle will be added to the fleet.
67 ITEM 6G
The Fiscal Year 2026-2027 adopted budget authorizes the Fire Department to purchase command and support vehicles. The Department has previously utilized state cooperative procurement agreements to purchase vehicles and equipment, allowing the City to take advantage of competitive bid pricing established through the state government contracts.
In consideration of Municipal Code Section 3-10.320 – Local Business Preference, staff also solicited quotes from the local dealership for the comparable model and brand. Below is the bid tabulation for this solicitation:
No. Dealership Bid Price 5% Local Preference Price
($5,000 Max)
1 Winner Chevrolet – Chevy
Tahoe SSV 4x4
$191,828.03 N/A
2 Santos Ford – Ford
Expedition Active
$212,731.53 $207,731.53
The lowest responsible bid is Winner Chevrolet/Elk Grove Auto Group at the total bid price of $191,828.03 ($63,942.68 per vehicle).
The purchase of these vehicles is consistent with the Council's approved budget for Fiscal Year 2026–2027 and will provide the necessary resources for the Fire Department administration and operations division to effectively serve the community.
The proposed vehicles are three (3) 2027 Chevy Tahoe’s which will be purchased through Winner Chevrolet / Elk Grove Auto Group. The dealership participates in multiple municipal purchasing agreements and is authorized under the State of California Cooperative Purchasing program. The City will utilize the State of California Contract No. 1-22-23-23D to complete this purchase. Leveraging the State contract allows the City to obtain competitive pricing that has already been publicly bid and negotiated, while ensuring compliance with procurement requirements and expediting the acquisition process.
The total purchase cost is within the budgeted amount approved by City Council. City Code Sec. 3-10.290 allows for the use of cooperative procurement: (b) Use of another entity’s contract. The City Manager may authorize the procurement of commodities, equipment and/or services through the use of a contract initiated by another governmental, public agency, provided that the original parties to the contract agree, the contract was awarded within twelve (12) months of the date of authorization, the contract is for identical or nearly identical goods and/or services, and the contract resulted from a competitive bid using methods similar to those required by this chapter. (§1, Ord. 1068, eff. February 1, 2008).
The remaining approved funds will be utilized to equip the vehicle with the necessary emergency lighting, communications equipment, vehicle cabinetry, safety components, and departmental graphics to ensure it is fully operational and compliant with City standards.

TYPE OF REPORT: Consent Agenda
SUBJECT: Cooperative Procurement of one BMW Police Motorcycle. ______________________________________________________________________ Recommendation:
That the City Council approve the purchase of one (1) 2027 BMW police motorcycle through the State of California Cooperative Purchasing Agreement from Long Beach BMW Motorcycles, utilizing available funds designated for a police motorcycle in the Fiscal Year 2026-2027 adopted budget.
Discussion:
The Los Banos Police Department has identified the need to add an additional police motorcycle to our Traffic Unit. During the current fiscal year, the Department has dedicated two police officers and one sergeant to a full-time Traffic Unit. This dedicated staffing has increased the Department's ability to conduct proactive traffic enforcement, address traffic safety concerns, investigate traffic collisions, and provide a visible enforcement presence throughout the community.
With the establishment of a full-time Motor Unit, an additional police motorcycle is necessary to adequately support the unit's operations and ensure the Department has sufficient equipment to maintain operational readiness. A dedicated motorcycle provides officers with increased maneuverability and accessibility for traffic enforcement, particularly in areas where traditional patrol 93 ITEM 6H
vehicles may be less effective. The motorcycle will also be utilized for special events, traffic control, collision reduction efforts, and other public safety operations.
The City Council approved funding for the purchase of a new 2027 BMW police motorcycle as part of the Fiscal Year 2026/2027 budget. The proposed motorcycle is a purpose-built law enforcement motorcycle and will be assigned to the Department's Motor Unit for use by the two officers and sergeant currently assigned to the unit.
The Department currently has three police motorcycles, including newer 2024 and 2025 models and one 2007 BMW motorcycle. With the addition of the new motorcycle, the 2007 BMW will be reassigned from frontline operations to serve as a dedicated training motorcycle. This will allow the Department to maintain a training motorcycle while ensuring that frontline Motor Unit personnel have reliable, fully operational equipment.
The addition of this motorcycle will provide the Department with the necessary equipment to support its dedicated Motor Unit and enhance the City's ability to conduct proactive traffic enforcement, improve traffic safety, and provide effective law enforcement services throughout the community.
The proposed vehicle is one (1) 2027 BMW police motorcycle, which will be purchased through Long Beach BMW Motorcycles. The dealership is an authorized vendor under the State of California Cooperative Purchasing Program. The City will utilize State of California Contract No. 1-22-23-30 Motorcycles to complete this purchase. Leveraging the State contract allows the City to obtain competitive pricing that has already been publicly bid and negotiated, while ensuring compliance with applicable procurement requirements and expediting the acquisition process. The total delivered cost of the motorcycle is $44,301.91.
The total purchase cost is within the budgeted amount approved by City Council.
City Code Sec. 3-10.290 allows for the use of cooperative procurement: (b) Use of another entity’s contract. The City Manager may authorize the procurement of commodities, equipment and/or services through the use of a contract initiated by another governmental, public agency, provided that the original parties to the contract agree, the contract was awarded within twelve (12) months of the date of authorization, the contract is for identical or nearly identical goods and/or services, and the contract resulted from a competitive bid using methods similar to those required by this chapter. (§1, Ord. 1068, eff. February 1, 2008. 94 The remaining approved funds will be utilized to equip the vehicle with the necessary emergency lighting, communications equipment, safety components, and departmental graphics to ensure it is fully operational and compliant with City standards.
Total: $44,301.91
The corresponding account number is as follows:
Expenditures:
Specialized Equipment: 100-421-140-755 $44,301.91
Fiscal Impact:
Funding for this purchase has been identified in the Fiscal Year 2026-2027 Police Department Budget, line item 100-421-140-755, and was approved by the City Council on June 17, 2026. Additional costs associated with the motorcycle, including the radio head unit, Bluetooth helmet adapter, and vehicle decals can be accommodated within current budget appropriations.

Agenda Staff Report
TO: Mayor Amabile and Council Members
FROM: Mary Lerner, City Attorney
DATE: September 2, 2026
TYPE OF REPORT: Consent
SUBJECT: Renewing Sections 4-12.01 through 4-12.06 of Title 4, Chapter 12 of the Los Banos Municipal Code – Military Equipment Use
______________________________________________________________________ Recommendation:
Staff recommend that the City Council renew the City’s Military Equipment Use Ordinance at sections 4-12.01 through 4-12.06 of Title 4, Chapter 12 of the Los Banos Municipal Code and find that such continues to satisfy the standard for approval set forth in California Government Code section 7071.
Discussion:
Government Code section 7071(e) requires the City Council to annually review the Military Equipment Use Ordinance and determine whether continued authorization remains appropriate.
Specifically, the City Council must determine whether each type of military equipment continues to satisfy the approval standards established in Government Code section 7071(d), including whether:
• The military equipment is necessary because there is no reasonable alternative that can achieve the same objective of officer and public safety; • The proposed use of military equipment safeguards the public's welfare, safety, civil rights, and civil liberties;
105
ITEM 6I
• The purchase of equipment is reasonably cost effective compared to available alternatives that can achieve the same objective of officer and civilian safety; • Appropriate policies, procedures, and training remain in place; • Adequate oversight mechanisms exist to ensure compliance with applicable laws and departmental policy;
• The equipment has not resulted in unlawful or inappropriate uses inconsistent with the approved policy.
The Annual Military Equipment Report demonstrates that the Department has continued to utilize approved military equipment consistent with the adopted Military Equipment Use Policy. The report identifies the equipment used, describes operational deployments, summarizes required training, identifies any complaints or policy violations, and outlines associated costs.
Staff has reviewed the report and determined that the elements set forth in Government Code section 7071(d) and outlined above continue to be met. As such, no modifications to the Military Equipment Use Policy are recommended at this time.
In addition, on August 21, 2026 the required Community Engagement meeting occurred as noticed to the public. The Community Engagement meeting was attended by 4 members of the community. They were all in support of the continued use of military equipment. One of the community members mentioned that the police department should have a bearcat (armored vehicle). The community members also mentioned they believed the Police Department should have all necessary equipment to ensure the safety of the community.
Accordingly, staff recommends renewal of the ordinance authorizing continued funding, acquisition, and use of the approved military equipment.
Should the City Council determine that any category of military equipment has not complied with the statutory approval standards, Government Code section 7071(e)(2) requires the Council to either deny renewal for that category of equipment or direct modifications to the Military Equipment Use Policy sufficient to bring the equipment into compliance.
Fiscal Impact:
Renewal of the Military Equipment Use Ordinance does not authorize any additional appropriations beyond those approved through the City's annual budget process. Existing operational and maintenance costs are identified in the attached Annual Military Equipment Report and are funded through the Police Department's adopted budget.

Agenda Staff Report
TO: Mayor & City Council Members
FROM: William Via, Jr., Public Works Director
DATE: September 2, 2026
TYPE OF REPORT: Agenda Item
SUBJECT: Chromium VI Treatment Engineering Report
______________________________________________________________________ Recommendation:
Receive the Hexavalent Chromium Treatment Pre-Design Report prepared by Provost & Pritchard Consulting Group, provide direction to proceed with final design of the City's first Full Scale Pilot Reduction-Coagulation-Filtration (RCF) treatment facility at Well 9, and pursue funding opportunities for implementation of the City's chromium compliance program.
Background:
The City serves approximately 49,255 residents through 13,898 service connections and relies entirely on groundwater supplied from 13 municipal wells. Historically, the City complied with both state and federal chromium regulations. The California Division of Drinking Water adopted a Maximum Contaminant Level (MCL) for Hexavalent Chromium (Cr6) of 10 parts per billion (ppb) effective October 1, 2024. All thirteen active City groundwater wells exceed the new standard and require treatment for compliance. The City has received a compliance extension through December 2030 in accordance with the approved Compliance Plan from the State Division of Drinking Water.
Discussion:
Provost & Pritchard has completed a comprehensive pre-design evaluation of alternatives and pilot-tested treatment technologies. The report concludes that Reduction Coagulation 119
ITEM 7
Filtration (RCF) is the most feasible and practical approach for achieving compliance with the new chromium standard. Small scale pilot testing demonstrated successful removal of chromium to below regulatory requirements while also providing incidental arsenic removal.
Several alternative concepts were also evaluated by P&P, including:
• Consolidation
Consolidation with neighboring water systems was determined to be infeasible because nearby systems lack sufficient capacity and experience elevated chromium levels.
• New or Replacement Wells
Hydrogeologic investigations indicate chromium contamination is naturally occurring throughout the region. Additional shallow wells are unlikely to meet the new standard, and deeper wells below the Corcoran Clay are restricted due to groundwater subsidence concerns and existing county regulations. • Surface Water Supply
Development of a surface water supply remains a long-term strategy; however, acquisition of water rights, construction of treatment facilities, and distribution system improvements are estimated to cost in excess of $250 million and cannot be completed within the current compliance schedule.
• Alternate Treatment Technologies
Ion Exchange (IX) and Reverse Osmosis (RO) were evaluated but were found to be less favorable due to water quality constraints and concentrated waste disposal challenges.
Pilot testing for RCF was conducted at Wells 5 and 12 during 2025 and 2026. Key findings include:
• Successful reduction of hexavalent chromium below treatment goals. • Simultaneous removal of arsenic was demonstrated.
• Pyrolusite media outperformed conventional sand and anthracite media, allowing higher loading rates and longer filter runs.
• Water recovery rates ranged from approximately 96% to 98.5%. • Direct sanitary sewer disposal of filter backwash water appears feasible at many sites and would significantly reduce operational complexity.
The report also identified several operational variables requiring additional investigation, including chromium spikes following extended treatment system shutdowns and longterm impacts of silica accumulation on filter performance.
The report recommends implementation of RCF treatment using modular filtration systems with pyrolusite media. A phased implementation approach is advised, beginning 120
with construction of a full-scale pilot treatment facility at Well 9. Well 9 was identified as the preferred initial project because:
• Adequate site space exists for treatment facilities.
• Large sanitary sewer infrastructure is available for backwash disposal. • The site presents fewer construction constraints than many other wells. • Lessons learned can be applied to future treatment plant designs citywide. • Financial Impact
• Capital Costs
Preliminary estimated capital costs for stand-alone treatment facilities range from approximately $2.6 million at smaller sites, $5.9 million for centralized treatment of Wells 1, 2, and 3, and $12.9 million for a centralized facility serving Wells 5, 7, 9, and 13. The estimated capital cost for the recommended Well 9 treatment facility is approximately $2.97 million.
Annual Operations and Maintenance Costs for Citywide implementation of chromium treatment is projected to also increase annual operating costs by approximately:
• $540,000 for ferrous chloride
• $351,000 net increase for sodium hypochlorite
• Approximately 4,700 hours of additional operator labor • Approximately $17,700 annually for laboratory testing • Approximately $25,000 annually for increased power consumption Implementation of chromium treatment facilities will have operational impacts and will require:
• Additional certified treatment operators.
• Increased chemical handling and delivery coordination. • Additional laboratory compliance monitoring.
• Potential modifications to current well operation priorities to maximize treatment efficiency.
• Upgrades to instrumentation and SCADA integration at treatment sites. • Environmental Review
Acceptance of the Pre-Design Report is not a project approval under the California Environmental Quality Act (CEQA). Environmental review will be conducted as part of the final design and project implementation phases. Further action authorizing design or construction will be brought back to the City Council as required.
Fiscal Impact:
There is no fiscal impact arising out of this report. The costs associated with the design and construction of the full-scale pilot study at Well #9 are included in the approved 121
2026/2027 Fiscal Year budget in line items 501-461-100-726 (Water) and 511-461-100- 726 (Water Restricted).

1 BACKGROUND AND INTRODUCTION
1.1 INTRODUCTION
The City of Los Banos (City) is located within the western San Joaquin Valley near the Coastal Mountain Range, approximately 25 miles southwest of the City of Merced and has an approximate population of 47,350 people. The City operates a public drinking water system with 13,484 service connections that is regulated by the California State Water Resources Control Board – Division of Drinking Water (DDW). The City’s drinking water is supplied by 13 groundwater wells. Figure 1-1 is a map showing the locations of the City’s wells and other relevant features.
DDW is required to set and enforce drinking water standards that are at least as stringent as those set by the US Environmental Protection Agency (USEPA). Prior to October 1st 2024, total chromium (including hexavalent and trivalent chromium) was regulated with a California MCL of 50 parts per billion (ppb), which was already more stringent than the EPA MCL of 100 ppb. The City of Los Banos was in compliance with the state and federal regulations at all times. On June 16th 2023, the Division of Drinking Water proposed a more stringent regulation to limit hexavalent chromium (Cr(VI)) to 10 ppb. That regulation went into effect on October 1st, 2024. All Thirteen (13) of the City’s wells are out of compliance with this new standard.
The remainder of this report is specifically focused on the feasibility of using the Reduction-CoagulationFiltration (RCF) treatment process to treat the City’s wells for Cr(VI). However, background information related to other non-treatment and treatment alternatives the City has considered has been included within this report section for context.

1.2 BACKGROUND
Chromium is a metallic element found in rocks, soils, plants, and animals. It is the 21st most abundant element in the Earth’s crust. Naturally occurring chromium is found extensively and has industrial uses in metal plating, leather tanning, corrosion inhibitors, paints, and dyes. Chromium exists in several forms including trivalent, hexavalent, and metallic forms.
The State of California has identified Cr(VI) as a carcinogen when ingested. Cr(VI) occurs in groundwater contaminated by natural sources as well as from man-made contamination. Geologic conditions on the west side of the Central Valley, near the Coastal Mountain Range are known to create the potential for hexavalent chromium contamination of groundwater when water flows underground through minerals that naturally contain chromium (Izbicki 2015). Los Banos is located within this area. Levels of hexavalent chromium above the new drinking water limit have been detected along the Coastal Range from Los Banos to at least as far north as Patterson. Such a large area of contamination is likely to be naturally occurring and there is no record of any industrial discharge of hexavalent chromium that would affect the City’s groundwater wells. Refer to Evaluation of Probable Source of Cr(VI) in Los Banos Groundwater (Provost & Pritchard 2018).
Hexavalent chromium is referred to using many formal and informal terms. The terms hexavalent chromium, chrome six, Cr(VI), and Cr +6 all refer to the same substance and are used interchangeably.
1.3 REGULATORY HISTORY
1.3.1 HEXAVALENT CHROMIUM
In 2014, the State of California approved a new drinking water quality standard establishing a Maximum Contaminant Level (MCL) for hexavalent chromium of 10 ppb, lowering the earlier California standard of 50 ppb. In 2017 the regulation was challenged in court and rescinded for improperly considering the economic feasibility of affected water systems that were required to comply with the MCL. On June 16, 2023, the state again proposed an MCL for Cr(VI) in drinking water of 10 ppb. That regulation went into effect on October 1, 2024.
1.3.2 ARSENIC
Prior to the spring of 2026, DDW was considering lowering the existing arsenic MCL from 10 ppb. It was widely speculated that a new MCL would be set no higher than 5 ppb. This is relevant to the City’s Cr(VI) mitigation efforts because several of the City’s wells have arsenic levels greater than 5 ppb. This was the reason the 2025 reduction coagulation filtration (RCF) pilot study investigated simultaneous removal of Cr(VI) and arsenic. In the Spring of 2026, DDW informally announced that they had reached a determination not to reduce the arsenic MCL at this time. They determined that the economic impact of lowering the MCL outweighed the health benefits.
1.4 ALTERNATIVES CONSIDERED
The purpose of this report is to evaluate the feasibility of the reduction-coagulation-filtration (RCF) groundwater treatment process for removing Cr(VI) at the City’s wells. The following background information related to other non-treatment and treatment alternatives considered by the City is intended to provide context for why the City has identified RCF as a critical element in its response to the new regulation.

1.4.1 CONSOLIDATION
The nearest utility of comparable or larger size to Los Banos is the City of Merced, which is approximately 25 miles north-east of Los Banos. Other existing water systems that are close to Los Banos are the communities of Volta and Gustine. Both water systems are significantly smaller and lack the infrastructure to supply the City. Both systems also have ongoing water quality issues including hexavalent chromium above the new MCL. Consolidation is not a practical alternative to resolving the City’s problem.
1.4.2 REPLACEMENT WELLS
Groundwater on the west side of the Central Valley near the coastal mountains is naturally prone to elevated levels of hexavalent chromium due to geologic conditions. Drilling new wells was considered in Provost & Pritchard’s 2016 Well Replacement Alternative Evaluation, and it was concluded that it is very unlikely that the City can drill new shallow or deep wells to replace the entire capacity of the City’s existing wells. Drilling new shallow wells within or in close proximity to the City likely will not produce water with Cr(VI) levels below the MCL. Only wells near Los Banos Creek and the Delta Mendota canal have been found to produce water with Cr(VI) concentrations below the 10 μg/L. However, it is uncertain if these wells pull water from the deep aquifer. The well near Los Banos Creek was tested during a period of significant releases from the Los Banos Reservoir into the creek, which would have provided a source of recharge for the well with uncontaminated water. Further testing would be needed to investigate Cr(VI) levels during periods when the creek is dry. The well located near the DMC may have been influenced by seepage from the canal. The prevailing direction of groundwater flow is to the northeast.
Levels of Cr(VI) generally trend upward in the direction of groundwater flow. Wells in the southwestern (upgradient) portion of the City, with the lowest Cr(VI) levels, still average greater than 20 ppb, twice the MCL.
Replacing the City’s wells with deep wells, pumping water from below the Corcoran Clay, would likely produce water with lower Cr(VI) levels, but is not considered feasible because tapping the aquifer below the Corcoran Clay layer can result in increased subsidence near the many canal structures passing through the vicinity of Los Banos including the California Aqueduct, Delta Mendota Canal, and Central California Irrigation District (CCID) Main and Outside Canals. Uneven subsidence along a canal alignment can reduce the capacity of the canals and disrupt canal regulating structures. At least in part due to these subsidence concerns, the Merced County Groundwater Ordinance enacted in April 2015, does not allow constructing new wells below the Corcoran Clay. CCID has also said that they are opposed to any increase in pumping from below the Corcoran Clay.
As a result of increasing supply needs, the City is constructing a new well, Well 16, which will be located approximately ½ mile west of Well 11, which would make it the City’s most westerly located well. It will also be located close to Los Banos Creek – a potential source of recharge that is not contaminated with Cr(VI). There is a possibility that Cr(VI) levels are lower in that area.
1.4.3 SURFACE WATER
The City of Los Banos is located near several large water conveyance facilities including the CCID Main and Outside Canals, the Delta Mendota Canal, and the California Aqueduct. However, the City does not possess any surface water rights. The City’s Water Master Plan includes plans for future development of a surface water supply. In addition to the Cr(VI) issue, the need for surface water is primarily driven by groundwater pumping limits stipulated in the basin’s Groundwater Sustainability Plan (GSP) developed to comply with the California Sustainable Groundwater Management Act (SGMA). In the near term, there are three major obstacles to the City developing a surface water supply as a means of coming into compliance with the Cr(VI) MCL: water rights, cost, and schedule. The City will need to buy surface water 137
City of Los Banos August 2026
Cr(VI) Treatment Engineering Report
Section One: Introduction

rights from one or multiple current rights-holders to ensure a consistent and reliable source of water to meet demand, even during drought years. It is predicted that design and construction of a surface water treatment plant, raw water conveyance facilities from the canals to the treatment plant, and improving its water distribution system to distribute the treated water across the service area will cost more than $250 million. The Cr(VI) set a deadline for water systems to comply with the Cr(VI) MCL of October 1, 2026. The City has been granted an extension of that deadline until December of 2030. Even with the extended deadline, it is unlikely the City can develop a surface water supply and construct a surface water treatment plant in time.
1.5 GROUNDWATER TREATMENT
After concluding that consolidation, replacing wells, and surface water treatment are not feasible, the last alternative available to the City is to treat its wells.
The DDW recognized Best Available Technologies (BATs) for removing Cr(VI) from drinking water are ion exchange (IX), reverse osmosis (RO), and reduction-coagulation-filtration (RCF). The IX and RO technologies are briefly described below. RCF is addressed in more detail in later report sections.
1.5.1 ION EXCHANGE
1.5.1.1 PROCESS DESCRIPTION
Hexavalent chromium is present in drinking water in the form of chromate and dichromate - both negatively charged ions (anions). Ion exchange (IX) treatment makes use of synthetic resins formulated to exchange an ion pre-loaded onto the resin for another ion in solution. In the case of Cr(VI), chloride is most often the ion pre-loaded on the resin and given up in exchange for taking the Cr(VI) out of the water. The number of exchange sites on the resin is limited. After treating a certain amount of water, the resin will have Cr(VI) and other competing ions attached to most of the exchange sites and the resin will no longer have capacity to remove Cr(VI) down to the targeted concentration. The resin will then need to be regenerated or replaced.
There are three approaches to using IX for treatment of Cr(VI): strong base regenerable IX, strong base single use IX, and weak base single use IX.
Strong base anion (SBA) resin is most often reused multiple times with the resin being regenerated using a brine solution produced on-site or potentially using a third-party roll up brine transport and regeneration system. Large volumes of waste brine are produced during the regeneration process. It can be assumed that a volume of waste brine at least 0.3 – 0.5% of the wells production volume will be generated. Disposal of the brine is typically the highest operating cost item and often leads to the IX process being economically infeasible. Regenerable SBA is used for the removal of a range of contaminants from drinking water including nitrate, perchlorate, and Cr(VI). A significant issue with the use of SBA is that it also removes anions other than Cr(VI) from the water. Sulfate and nitrate, if present at modestly elevated levels, will lead to significantly shortened intervals between regeneration cycles.
These constituents are present in the water at parts per million (ppm) levels as opposed to Cr(VI), which is present in parts per billion (ppb) levels. Uranium is another anion that is incidentally captured by IX treatment. In some cases, the build-up of uranium on the resin is the limiting factor in how long the resin bed can stay in service before becoming a low-level radioactive waste. 138

Cr(VI) Treatment Engineering Report
Section One: Introduction
1-4
Rarely, with source waters that are exceptionally low in sulfate, nitrate, and uranium, it may be possible to get long enough resin life that the resin can be disposed of and replaced instead of being regenerated.
Operating a SBA IX system in this mode is referred to as single-use IX.
Weak base anion exchange (WBA) is a resin that has a different chemical structure than SBA resin. It is highly effective at removing Cr(VI) from water and is typically employed as a single-use resin. However, there are major disadvantages to WBA treatment including: the pH of the water must be reduced to approximately 5.5 – 6.0 for WBA to work and it can easily accumulate enough uranium to be considered a low-level radioactive waste. For these reasons few, if any, utilities in California are using WBA treatment.
Importantly, the water produced by the City’s wells has moderate to high levels of sulfate (40 – 400 mg/L), high chloride (61 - 340 mg/L), and at most wells, moderate to high levels of uranium (typically greater than 3 pCi/L and as high as 20 pCi/L (the MCL) at two of the wells. These water characteristics pose significant challenges for IX treatment of Cr(VI).
1.5.1.2 LOS BANOS PILOT TEST
A brief pilot test of SBA treatment at the City’s wells was conducted in late 2014. Wells 09 and 14 were chosen to bracket the range of water characteristics at the other wells. Well 14 represents water with near maximum levels of sulfate, chloride, uranium, and TDS. Well 09 represents water with low to average levels of these constituents. The results of that study were that Cr(VI) broke through into the treated water after treating only 1,300 bed volumes (BV) of water at Well 14. Breakthrough at Well 9 occurred after treating approximately 10,000 bed volumes of water. These results indicate that treatment of Well 14 using SBA would be infeasible. While the Well 9 results were better than at Well 14, they were still at the lower end of the range that would be expected. Based on the study results, the supplier that conducted the study did not pursue installing their equipment at any of the City’s wells.
1.5.2 REVERSE OSMOSIS
Reverse osmosis uses high feed pressures to push water through a semi-permeable membrane while any solids and most ionic constituents in the water are left behind. RO is highly effective at removing Cr(VI) from water. However, management of the waste (the concentrate) makes this process infeasible. The concentrate holds all constituents removed by the membrane, only concentrated in a smaller volume.
Even using multiple RO stages and an advanced RO system design, recovery of treated water is likely to be no more than 85%. The other 15% becomes concentrate that is continuously discharged whenever the RO system is in service. For a 1 million gallon per day (MGD) treatment plant, approximately 150,000 gallons of concentrate would be produced each day. The City has nowhere to send that waste. RO is not a workable solution to the City’s Cr(VI) problem.
1.5.3 ZERO VALENT IRON
The use of zero valent iron to remove Cr(VI) from water is a highly proprietary process marketed by North American Hoganas, a metal powder manufacturing company. It uses a porous iron media that possesses both adsorptive and reductive properties. The City of Los Banos collaborated with North American Hoganas to conduct a nearly one year-long pilot study at Well 14. The pilot study was conducted at no cost to the City. The pilot study was successful overall, but the process was expensive, somewhat complicated to implement, and needed extensive post-treatment. Zero valent iron is not recognized by DDW as a BAT and the company marketing the product is no longer in the water treatment business. 139

2 WATER QUALITY
2.1 GENERAL
In addition to elevated levels of Cr(VI), the City’s wells have elevated levels of other water quality constituents, including nitrate, uranium, sulfate, selenium, boron, and arsenic. These constituents could affect the City’s Cr(VI) mitigation program in three ways:
1. The presence of constituents other than Cr(VI) at levels near or over their regulatory standard, such as nitrate at Wells 2 and 7, and uranium at Well 7 suggests the possibility of blending water from multiple wells together at a centralized Cr(VI) treatment plant to simultaneously address Cr(VI) and the other potential regulatory issue(s).
2. Some constituents, such as silica, can interfere with the RCF treatment process.
3. Some constituents, such as selenium and boron, can affect the City’s ability to physically exchange groundwater for surface water should the City pursue developing a surface water supply now or in the future.
2.2 HEXAVALENT CHROMIUM
Hexavalent Chromium levels at the City’s 13 wells are summarized in Table 2-1. At well 15, levels of Cr(VI) below the 10-ppb MCL have been reported twice out of 42 samples analyzed. Cr(VI) levels at Well 15 more typically range from 15 - 20 ppb. In Figure 4-1 the Cr(VI) levels at all thirteen wells are plotted over the period of October 2013 through March 2025. Cr(VI) levels at all the wells fluctuate considerably over time. The only clear long-term trends are the rising levels at Wells 5 and 7 starting in 2020. Those two wells are located within ½ mile of one another in the central part of the city. Also notable are how closely the peaks in Cr(VI) levels at many of the wells coincide during certain sampling events (March 2018, December 2021, and October 2022).

2.3 NITRATE
The MCL for nitrate is 10 mg/L (measured as N). Elevated levels of nitrate can result in acute short-term health effects on certain populations. Because of this, compliance with the standard is based on any individual result exceeding the MCL value, as compared with other contaminants, like Cr(VI), for which compliance is based on a four-quarter rolling average of results. Wells 2, 5, and 7 have at least one test result that exceeded the MCL. Centralized treatment of one or more of these wells could potentially mitigate nitrate issues by blending with water from other wells.

2.4 URANIUM
The MCL for uranium is 20 pCi/L. The levels of uranium at Well 7 exceed the MCL so the well has been placed on standby. The possibility of blending Well 7 with another nearby well in conjunction with centralized treatment of Cr(VI) could be a means of recovering the approximately 1,350 gpm that could be produced by Well 7. The levels of uranium at several of the wells are high enough to be problematic with IX treatment approaches.

Total Dissolved Solids (TDS) in drinking water are regulated under Secondary Drinking Water Standards, which are based on aesthetic considerations including taste and mineral scaling. Elevated TDS interferes with IX treatment processes. Elevated TDS levels may also limit potential water exchange scenarios with CCID. The DDW upper-level limit for TDS is 1,000 mg/L.

in several of the City’s wells being out of compliance with another regulatory standard. The RCF pilot study proved that simultaneous removal of arsenic and Cr(VI) is feasible and would likely be achieved as an incidental benefit of RCF treatment.

2.11 SURFACE WATER EXCHANGE
One Cr(VI) mitigation alternative being considered by the City is developing a surface water supply. One potential means of potentially facilitating this is to exchange groundwater pumped from the City’s wells for surface water. However, the San Joaquin River Exchange Contractors will require that the groundwater meet certain water quality limitations. Preliminary discussions with CCID prior to the previous MCL being rescinded indicate that those limitations will include:
TDS less than 2,500 mg/L
Boron less than 2 mg/L
Selenium near or below detection limit

There are many documents that describe the capacities of the City’s wells, none of which agree. The Design Basis well capacities were provided by the City specifically for the purpose of analysis of Cr(VI) mitigation alternatives. However, some of these flow rates differ significantly from those contained in the 2010 Master Plan and the 2022 pump efficiency test reports. The City should confirm the Design Basis values are correct to use for treatment equipment sizing. At most wells, the Design Basis flow rates are greater than the other two sources and the treatment plant descriptions in this report should therefore be conservative.

4 WELL DESCRIPTIONS
4.1 COMMON WELL EQUIPMENT AND OPERATIONS
4.1.1 WELL PUMP CONTROLS
All thirteen of the wells are controlled by the City’s central SCADA system located at the Corporation Yard via low frequency (900 Hz) radio communications. Well pumps are enabled in either motor or engine mode using switches at a well status panel. The status panel also allows the operator to select low or high speed for wells equipped with multi-speed motors. When the wells are enabled at the status panel, they are turned on and off by SCADA based on the pressure at the bottom of the elevated storage tank located at the Corporation Yard and by the time of day. There are no pressure transmitters at the wells but the SCADA system does receive well flowmeter data.
Speed adjustment for pumps equipped with variable frequency drives (VFDs) must be carried out by an operator on-site at the well.

5 RCF TREATMENT PROCESS DESCRIPTION
5.1 RCF PROCESS OVERVIEW
Reduction-coagulation-filtration (RCF) is recognized by the California State Water Resources Control Board as a best available technology (BAT) for the treatment of hexavalent chromium in drinking water.
RCF Treatment typically involves the following components and treatment steps:
1. Water is dosed with a ferrous iron or tin-based reductant chemical, which then converts Cr(VI) to Cr(III) through the process of reduction.
2. The reductant chemical is allowed to react with the chromium in the water in a contact tank for from one to several minutes to allow the chromium to be fully converted to Cr(III).
3. After reduction of the chromium has completed, water is dosed with sodium hypochlorite to oxidize excess iron added during Step 1 so that it is filterable.
4. The water passes through filters that remove the precipitated Cr(III) and iron (or tin) from the water.
5. The filters need to be backwashed approximately every 12 – 24 hours depending on iron loading.
Backwashing produces thousands of gallons of backwash water that needs to be disposed of or reclaimed.
There are alternative ways of conducting most of the RCF treatment steps. The City and design engineer will need to make decisions on the reductant chemical, the filtration media type, the quantity and physical configuration of the filters, and the means of disposing of the filter backwash water. Each of these alternatives are discussed in more detail in the following report sections. Recommendations for each item are presented in Section 7.
5.2 REDUCING AGENTS
The first step in the RCF treatment process is to convert soluble Cr(VI) into relatively insoluble Cr(III). The Cr(III) can then be filtered out of the water. Ferrous iron-based chemicals (ferrous chloride and ferrous sulfate) have the advantage of being able to simultaneously function as a reductant and a coagulant.
Coagulation is necessary so that the precipitated solids are large enough to be effectively filtered.
Additionally, prior studies have shown that simultaneous removal of arsenic and Cr(VI) can be achieved with these chemicals. Ferrous chloride has the advantage of being delivered in more concentrated form than ferrous sulfate, which results in fewer chemical deliveries.
Stannous tin is an alternative, non-iron based reductant that has been investigated for use in Cr(VI) treatment. The stannous can be supplied either in the form of stannous chloride, or electrolytically generated stannous. Stannous chloride readily degrades in storage if exposed to any atmospheric oxygen. This significantly limits the duration that bulk-delivered liquid stannous chloride can be stored.
Additionally, stannous chloride has extremely limited commercial availability compared to the ferrous chemicals. Generating stannous on-site using an electrolytic process with tin electrodes was pilot tested at Los Banos Well 14. The pilot-scale stannous generator was effective and reliable at reducing the Cr(VI) to Cr(III). However, the process is proprietary, with only a single manufacturer to service the equipment and supply replacement electrodes. The process may also require dosing a separate coagulant as well as dosing an acid into the side-stream of the water that supplies the stannous generator. Prior pilot testing of the stannous generation system at Well 14 was focused on generation of the reagent and its effectiveness as a reductant. Further pilot testing would be needed to investigate the filterability of the resulting tin and chromium precipitates and to determine what supplementary chemicals may be 168

required.
It is noted that within the last few years, investigations were conducted into the possibility of reducing the Cr(VI) to Cr (III) using stannous and then discharging the Cr(III) with the tin directly into the distribution system. It was reasoned that the 10 µg/L MCL applied to Cr(VI), not Cr (III). This concept has been abandoned for the following reasons:
1. The Cr(III) in the distribution system is converted back to Cr (VI) by the oxidizing environment created by chlorine in the water. DDW was not convinced that this re-oxidation would not result in a Cr(VI) MCL exceedance in the distribution system.
2. Tin has been deliberately dosed into water systems for the purpose of corrosion control. One mechanism that contributes to the corrosion control is that the tin adheres to / coats the surfaces it comes into contact with. There are concerns that the chromium may be captured by this tin coating and biofilm and then unpredictably be released back into the water with high concentrations of Cr(VI).
5.3 FILTRATION
5.3.1 FILTRATION MEDIA
RCF can be carried out with either granular filter media or microfiltration/ultrafiltration membrane filters.
Due to the cost and complexity of implementing membrane filtration at multiple treatment sites, membrane filters are not considered further in this report.
There are several types of granular filtration media that can be used. The three most common alternatives are:
1. Conventional sand and anthracite,
2. Pyrolusite/manganese dioxide coated media, and
3. Manufactured ceramic media
The difference in cost between the conventional and pyrolusite media is typically relatively small in the context of the overall project cost. Pyrolusite will be more expensive than sand on a volumetric basis but will also require the use of smaller and/or fewer filters than sand and anthracite.
Ceramic media is less often used. Due to budget limitations, ceramic media were not evaluated during the City’s 2025/2026 pilot study. Information regarding the use of ceramic media in RCF treatment is limited and conflicting. There are published pilot study results that compared certain performance parameters for ceramic, pyrolusite, and sand and anthracite media (Gorman et al. 2022). The study reported that filter run lengths (limited by head loss) were longer with ceramic media than with pyrolusite or conventional media. The study did not measure Cr(VI) removal effectiveness at the end of the run. ATEC Systems reports that they have experience pilot testing Cr(VI) removal using ceramic media at another utility with poor results.
5.3.2 FILTER VESSEL CONFIGURATION
The required total filter area is determined by the maximum filter loading rate (gpm/ft2) successfully achieved during the pilot study, the capacity of the treatment plant and prior experience. However, to provide the total filter area, there are multiple filter vessel configurations that can be used. Filter vessels will be operated under pressure and can be either horizontally or vertically oriented. There is also flexibility regarding the quantity of independent filters.

whether the plant includes a single filter of a given surface area or includes four filters – each with onefourth of the surface area of the single filter. When considering the type and quantity of filter vessels, it should be noted that with pyrolusite media, the use of four or more independent filters allows for the backwashing of one of the filters using only the treated water that is being produced by the three filters that are still on-line (i.e. the treatment plant would be self-backwashing). If four filters are used, the treatment plant would not be producing water during a backwash but it would also not be pulling water from the distribution system. With filter quantities greater than four, the treatment plant could still supply some water to the distribution system while a single filter is being backwashed. Additionally, the more independent filters that are used, the lower the backwash water flow rate. It has been assumed that the City’s water distribution system cannot accommodate the large, short-duration water demand spikes that would occur during backwashing if less than four independent filters are used.
Most of the City’s wells could be treated using a single large horizontal filter vessel divided into four cells – a “horizontal multi-cell filter”. The vessel, resembling a hydropneumatic tank, would have internal dividers/bulkheads and independent headers, underdrains, and valves for each of the filter cells.
Horizontal multi-cell filters are the most space efficient alternative but produce high backwash flow rates – even when separated into multiple cells.
Small-vessel modular filtration systems (modular systems), such as those marketed by ATEC, utilize four or more vertical filter vessels with diameters of 48-inches or less to take best advantage of the selfbackwashing concept and to minimize backwash flow rates.
For the City’s proposed treatment plants, large diameter vertical vessels offer no significant advantage over the other two configurations and are not considered further.
5.4 BACKWASH WATER HANDLING
RCF filters must be backwashed typically every 12 – 24 hours of continuous operation. Each backwash cycle, consisting of backwashing all filters sequentially, will generate very dilute backwash water that must be disposed of. The backwash water flow rate is a function of the filter area of a single vessel/cell and will range from approximately 220 gpm for modular systems to as high as 1,500 gpm for horizontal multi-cell systems. The volume of waste produced per cycle ranges from 10,000-gallons at the City’s lower capacity wells, 32,500 gallons at Well 10, and as high as 77,500 gallons for potential centralized treatment alternatives. Backwash water is the primary waste product of the treatment process, and it will have elevated levels of chromium, iron, and arsenic. Because of these elevated levels, it has been assumed that discharge of backwash water to the storm drain system will not be permitted. There are four ways the backwash water can be managed.
1. Direct discharge to a nearby sewer through an air-gap,
2. If the nearby sewer is small, the backwash water can be discharged into an equalization tank that is slowly drained into the sewer,
3. Trucking the dilute backwash water to a suitable disposal site (potentially the City’s WWTP), and
4. Discharge into a storage tank followed by recycling the relatively clear decant water at the top of the tank by sending it back to the head of the treatment plant. The partially thickened sludge that builds up on the bottom of the tank would need to be further thickened and dewatered for disposal as a solid, likely hazardous waste.
Direct discharge to the sewer, where possible, will be the lowest cost alternative. The last alternative, to reclaim the backwash water, would significantly enlarge the treatment plant footprint, increase cost, and increase operational complexity.

There are logistical challenges with direct discharge to the sewer. Even though it is described as “direct” discharge in this report, there will need to be an air gap between the filter backwash manifold and the sewer inlet – leaving the sewer potentially open to the air. This creates potential for sewer odors to escape. Some of the City’s wells are located within residential neighborhoods, where odor complaints are more likely to occur. Therefore, an approach to avoiding the release of sewer gases will need to be developed during detailed design.
5.5 RESIDUALS MANAGEMENT
Treatment plant backwash water residuals having less than 0.5% solids are classified as liquid waste.
Backwash water that has not been allowed to settle is an example of liquid waste. Treatment plant residuals having more than 0.5% solids are considered a solid waste for the purpose of hazardous materials classification. One example is thickened sludge. For a waste to be disposed of at a solid waste landfill, it must also pass the Paint Filter Liquid Test showing the absence of free liquids. An example is dewatered sludge.
5.5.1 HAZARDOUS WASTE CHARACTERIZATION
Hazardous wastes that exceed a Federal regulatory limit are classified as Resource Conservation and Recovery Act (RCRA) hazardous waste. California has more restrictive limits for what is classified as a hazardous waste. Waste that is considered hazardous in California but does not exceed any federal RCRA limit is classified as non-RCRA California hazardous waste.
The residuals that will be generated by the RCF treatment plants will not have the hazardous characteristics of ignitability, corrosivity, or reactivity. However, depending on how they are managed, the residuals could be classified as hazardous based on the characteristic of toxicity. The method used to determine toxicity of solid wastes under RCRA is the Toxicity Characteristic Leaching Procedure (TCLP), which is designed to predict how toxic constituents would leach from waste if disposed of in a municipal solid waste landfill. In California, the extent that toxic materials would leach from the solid is assessed using the California-specific Waste Extraction Test (WET). The regulatory limit for the WET is referred to as the Soluble Threshold Limit Concentration (STLC). In California there are also added limits for the total concentration of constituents in the solid waste irrespective of leachability – referred to as the Total Threshold Limit Concentration (TTLC). The total concentration of each constituent is found by fully digesting the as-received sample and comparing it to the TTLC value. The result is reported on a wetweight basis, meaning that if a dilute sludge is tested, the weight of the moisture in the sample is included in the concentration calculation – the less the sludge is thickened, the lower the TTLC value.
The thresholds for the different tests and constituents of concern are as follows.

than 560 mg/L, the waste is not classified as hazardous (CCR §66261.24, Table II)
Backwash water discharged directly into the sanitary sewer would only be classified as hazardous liquid if the concentration of either arsenic or chromium in the water exceeded the Federal TCLP or the California STLC. The TTLC limit does not apply to liquids. Assuming a conservative treatment plant water recovery of 98% (i.e. the backwash water volume is 2% of the volume of well water being treated), and that the water produced by the well has arsenic and chromium levels of 0.010 and 0.060 mg/L, the maximum resulting concentration of arsenic and chromium in the backwash water would be 0.3 and 2.8 mg/L respectively, which is below the TCLP and STLC thresholds. The backwash water would not be expected to be classified as a RCRA or California non-RCRA hazardous waste.
Hower, once the solids in the backwash water are allowed to settle and gravity thicken in the bottom of a tank, they will at some point be classified as a solid (percent solids > 0.5%). At that time, all three of the limits (TCLP, TTLC, and STLC) would apply. Published studies and pilot testing at Los Banos show that thickened or dewatered sludge will comply with the soluble TCLP and STLC limits. However, as the sludge is further dewatered and the proportional weight of water is reduced, it is possible for the sludge to exceed the TTLC and be classified as a non-RCRA California hazardous waste.
5.5.2 DIRECT DISCHARGE TO SEWER
As described in Section 5.5.1, backwash water discharged directly into the sewer should not be considered a hazardous waste. However, other issues that should be addressed prior to direct discharge of backwash water into the sanitary sewer system are:
1. What is the fate of the arsenic, chromium, and iron in the backwash water?
2. Will it affect the ability of the WWTP to comply with Waste Discharge Requirements (WDR)?
3. Will it result in the hydraulic capacity of the WWTP being exceeded?
4. Will it disrupt the wastewater treatment processes?
5.5.2.1 FATE OF CHROMIUM AND ARSENIC
On May 11, 2025, the City tested water at the influent and effluent of the wastewater treatment plant (WWTP) for chromium and arsenic. The results are summarized in the table below. The data shows that all, or nearly all, of the chromium in the sewer system is in the trivalent state, Cr(III) when it arrives at the WWTP – only low levels of Cr(VI) enter the WWTP. Nearly all the chromium appears to settle out within the WWTP, presumably in the treatment ponds, and little is present in the storage pond effluent. The data also show that arsenic removal through the WWTP is not significant.

The chromium and iron removed by the WWTP ultimately ends up in the biosolids. As described in Section 5.5.1, elevated levels of chromium in solid waste can result in the waste being classified as hazardous. Given the high percentage of other inorganic and organic substances that will have accumulated in the biosolids, it is unlikely that the chromium levels will reach any of the toxicity limits.
However, waste profiling reports from previous sludge removal and disposal projects should be reviewed to confirm this assumption. Provost & Pritchard is not aware of any regulations that would restrict the concentration of iron in the biosolids.
5.5.2.2 COMPLIANCE WITH WDR
The City’s current WDR does not include any specific limits for iron, arsenic, or chromium in the treatment plant effluent.
5.5.2.3 WWTP CAPACITY
Based on the results of the pilot study, it has been assumed that the RCF treatment plants will have water recoveries of 95% or better. No more than 5% of the water treated would end up as backwash water.
Five percent of an assumed city-wide drinking water average daily demand of 7.1 MGD results in approximately 360,000 gallons of backwash water that would be entering the sanitary sewer system and arriving at the WWTP daily.
The WWTP has a current operating capacity of approximately 3 MGD and is limited by the WDR to 4.9 MGD. An added 360,000 gallons from the RCF treatment plants would be a 12% increase in WWTP flows. The projected 3.36 MGD flow into the WWTP would be well within the permitted 4.9 MGD but would nonetheless reduce the City’s flexibility to accept waste from other sources, including more sewer service connections, as the City grows.
5.5.2.4 WWTP PROCESS DISRUPTION
Elevated levels of metals have the potential to inhibit the growth and metabolism of the microorganisms relied on for proper function of the WWTP. Furthermore, the backwash water will have negligible biochemical oxygen demand (BOD), which would dilute the wastewater and affect the biological treatment process.
The increase in the influent concentrations of arsenic and chromium will be limited to some extent.
Currently the arsenic and chromium in the water produced by the untreated wells are distributed to homes and businesses, where approximately one half of the arsenic and chromium end up in plumbing fixture drains, and ultimately at the WWTP. The primary impact of RCF on these metals is that the arsenic and chromium will arrive at the WWTP in slugs as opposed to evenly spread throughout the day. Provost & Pritchard was unable to find any reports of negative impacts to wastewater treatment processes at the arsenic and chromium concentrations relevant to this project.
If the wells are treated with RCF, the WWTP influent iron concentrations will increase from approximately
1.1 mg/L to 7.4 mg/L – equivalent to an added load of 178 lbs of iron daily. Iron can, in some cases provide benefits to wastewater treatment processes including improved sludge settling, heavy metals removal, and phosphate removal. Provost& Pritchard was unable to find any reports of negative impacts to wastewater treatment processes at the iron concentrations relevant to this project. 173

Cr(VI) Treatment Engineering Report
Section Five: RCF Process Description
5-7
Current influent BOD5 levels average approximately 530 mg/L with 90% reduction through the WWTP.
The 12% increase in influent flow with negligible BOD5 would dilute the overall influent BOD5 to 473 mg/L.
This decrease in BOD is not expected to have any significant negative impact on the performance of the facultative treatment ponds used at the WWTP.
5.5.3 FLOW EQUALIZED DISCHARGE TO SEWER
Some of the wells are located near a sanitary sewer but the nearby sewer pipelines are too small to accommodate the backwash flow rates. Any sewer 6-inches and smaller will not have enough capacity for direct discharge. Eight-inch diameter sewers will need to be evaluated on a case-by-case basis. If a larger sewer cannot be extended out to the well site, it will be necessary to discharge the backwash water into a flow equalization tank sized to hold at least one full backwash cycle. The tank would include a drain valve that would be used to slowly release the water into the sewer.
5.5.4 TRUCKING OFF-SITE
For wells where there is no sewer, one possibility of disposing of the backwash water is to store it in a tank and periodically truck it off site. However, as potentially tens of thousands of gallons of backwash water could be produced during each backwash cycle, this may only be practical for wells that are infrequently used.
5.5.5 BACKWASH WATER RECLAIM
The complexity and cost of managing backwash water increases significantly when a sewer connection is not available. The treatment plants become zero liquid discharge facilities requiring all portions of the backwash water to be either recycled back to the front of the treatment plant or hauled off site by truck.
If the wells were located on large, City-owned parcels with acres of open space, evaporation could be considered. This is not the case at any of the City’s well sites. The process for reclaiming backwash water typically involves discharging the backwash water into a storage tank, allowing enough time for the sludge to settle to the bottom of the tank, followed by pumping the relatively clean water from the top of the tank (decanting) back to the head of the treatment plant using a floating pump inlet. The timing of when to recycle water from the tank is challenging because enough time needs to be provided for the sludge to settle, regulations limit the rate of recycling to 10% of the treatment plant capacity, and the pump needs to be stopped when the water level in the tank is still high enough to prevent sludge from being inadvertently pumped back to the treatment plant.
Sludge will build up at the bottom of the reclaim tank and will need to be periodically hauled off for proper disposal. If the sludge is not hazardous it could be trucked to the City’s WWTP. If the sludge cannot be accepted at the City’s WWTP, it will need to be dewatered on-site and taken to a conventional or hazardous waste solids landfill. Dewatering the sludge to remove all free liquid requires mechanical equipment such as a filter press or screw press and at the addition of at least one polymer, which would need to be prepared on-site from an emulsified form. Dewatering activities would require on-site operator involvement. The process of dewatering the sludge will create its own wastewater stream referred to as the pressate or filtrate. DDW does not typically allow reclaiming of pressate, so this liquid would need to be hauled off-site or potentially disposed of in a dry well.
As will be described in Section 6, the pilot study evaluated the settling characteristics of the backwash water. While the sludge settled quickly, the volume of sludge remaining was relatively large, showing that sludge removal and dewatering would need to occur frequently. 174

5.6 CONTROLS
5.6.1 EXISTING SCADA SYSTEM
The City’s well sites are equipped with Modicon 612 Micro programmable logic controllers (PLCs).
Operations staff report that the PLCs have been reliable. However, they are 25-years-old and are no longer supported by the manufacturer. Communications with the control center at the Water Corporation Yard is via low frequency 900 MHz radio. The City’s existing SCADA system supports the following functions:
1. Calling the well pump on or off
2. Selecting between motor and engine pump driver
3. Providing a run signal from well
4. Reporting the well flow rate
Individual wells are not equipped with pressure transmitters or pressure switches. The wells are controlled purely based on the pressure at the elevated storage tank at the Corporation Yard. Over the years, City operations staff have developed a feel for which wells need to be operated based on that single tank pressure reading.
5.6.1 RCF INSTRUMENTATION
The following additional instruments will be needed to monitor the RCF treatment process:
1. Free chlorine residual analyzer – failure to feed enough chlorine will result in iron and chromium breaking through the filter.
2. Turbidimeter (recommended) – Will detect solids that have broken through the filter
3. Backwash flowmeter – needed to properly set backwash flow rate. If the flow rate is too low, the filter run length will be shortened. If the flow rate is too high, media will be carried out of the filter with the backwash water.
4. Differential pressure transmitter – high differential pressure is a sign that the filter needs to be backwashed.
5. Discharge pressure transmitter – Once treatment is installed at all wells, the City will need the flexibility provided by being able to see distribution system pressures and to be able to control wells based on those pressures.
5.6.2 FILTRATION SYSTEM CONTROLLER
Filter systems can supplied with a remote I/O panel if primary control is through an existing site PLC, or, more commonly, a control panel with a dedicated PLC and touch-screen human machine interface (HMI).
Typical control functions that must be overseen by either the site PLC or the filter manufacturer’s control panel include:
1. Sequencing of actuated valve positions as required for normal operation, backwash, and filter to waste cycles
2. Valve position indication feedback
3. Initiating filter backwash cycles based on time in service, time of day, remote initiation, and/or pressure drop across the filter
4. Control of chemical dosing pumps including starting and stopping the pumps, adjusting the dosing rate based on the flow rate of the well (flow pacing), and in some cases also adjusting the chemical dosage based on feedback from a continuous water quality analyzer (compound loop control)
175
City of Los Banos August 2026
Cr(VI) Treatment Engineering Report
Section Five: RCF Process Description
5-9
5. If decanted backwash water is being recycled – the PLC will control the time delay after backwashing to allow for sludge settling and will call the recycle pump on and off based on the water level in the recycle tank
6. Monitoring and reporting continuous analyzer readings and alarms.
A simplified control approach is often used with modular filter systems. The filter control panel has more limited functionality but is less expensive and simpler to use. ATEC, for example, uses a dedicated commercial filter controller paired with hydraulically operated 3-port valves. Only one valve is installed on each vessel. These are components that are used extensively in agricultural irrigation filtration systems. The basic controller can start sequential backwashing of the filters based on elapsed time, differential pressure, and via a remote relay. The controller includes a single alarm, triggered by high differential pressure. An interface at the control panel allows the operator to see the time since the last backwash, adjust the differential pressure setpoint, adjust backwash intervals and durations, and the ability to enable and disable individual filters. The controller cannot connect directly with off-skid equipment such as chemical feed pumps and recycle tank pumps, and the only signal it can provide to SCADA is the high differential pressure alarm. This approach reduces cost and existing users report that it is simple to operate and robust, but it lacks flexibility.
As an option, ATEC can furnish their system with an I/O panel for interface with an external PLC for approximately $40,000 or a traditional control panel with PLC and HMI for between $70,000 and $100,000.
5.6.3 SCADA INTEGRATION
The integration of the RCF system controls with the City’s SCADA system can range from very limited to having full access to the treatment plant functions remotely.
5.6.3.1 MINIMAL INTEGRATION
While not recommended, the simplest and lowest cost control scheme that would be functional would consist of:
1. When the well is called on by the City’s existing SCADA system, the existing PLC, or a relay would be used to call the filter system on. If a modular filtration system with a simple filter controller is used, the power to the controller would be switched on or off to activate and deactivate the filtration system.
2. Similarly, the three chemical dosing pumps could be called on and off using a switched power supply tied to a relay activated when the well begins to flow.
3. Control of the dosing pump feed rates could be set manually at the pump. This will only work if the well flow rate stays relatively constant.
4. Backwashing of the filters and monitoring of differential pressure across the filters could be handled by the ATEC filter controller independent of the well site SCADA system
5. Discrete alarms from the chlorine residual analyzer, turbidimeter, and high filter differential pressure would be integrated into the existing PLC assuming there is sufficient available I/O.
In this alternative, the City would receive alarms from the analyzers and filter controller, but would have no remote access to analog readings and no ability to remotely control the treatment plant. 176

5.6.3.2 INTEGRATION UTILIZING FILTER CONTROLLER W/ PLC
If the filtration system is furnished with a PLC, the procurement specification can include requirements for it to provide off-skid controls for the metering pumps and monitoring of the analyzer analog readings and alarms.
5.6.3.3 UPGRADING THE WELL SITE PLC
Irrespective of whether the filter system is equipped with its own PLC, the City may wish to replace their existing PLCs with ones having more I/O capacity, more flexibility, and with manufacturer support. The table below includes a list of I/O commonly integrated with site PLCs and available remotely through SCADA.

6 RCF PILOT STUDY RESULTS
6.1 DESCRIPTION
A pilot study consisting of RCF testing at two of the City’s wells was conducted during October 2025 and February 2026. The purpose of the pilot study was to confirm that RCF is effective at removing Cr(VI) from the water and to better estimate parameters for design and operation of a full-scale treatment plant. At the time the pilot study protocol was prepared, DDW was openly discussing lowering the arsenic MCL from the current value of 10 ppb. It was widely speculated that the new MCL would be no greater than 5 ppb. Because several of the City’s wells produce water with arsenic levels greater than 5 ppb, one of the study goals was to assess the simultaneous removal of arsenic with Cr(VI). Simultaneous removal was achieved. However, DDW has since indicated that, due to projected prohibitive costs of implementation, reduction of the arsenic MCL is no longer being considered.
The City solicited proposals to conduct the pilot study from several prospective RCF system manufacturers. ATEC Water Systems was selected based on a competitive procurement process that considered the cost for conducting the study, experience with the RCF process, and schedule, among other factors. The study included testing of RCF at two wells: Wells 5 and 12. Well 5 was selected because the water quality at that well represents what is expected to be the most challenging treatment conditions; producing the highest, or near highest, levels of alkalinity, Cr(VI), silica, sulfate, and total dissolved solids (TDS). Well 12 was selected because its water quality is more typical of water quality conditions at the City’s wells. Both wells were tested over a 1-week period in October 2025. Laboratory total and hexavalent chromium results, which were only available after ATEC had de-mobilized their pilot trailer, indicated that the Well 12 test successfully met the treatment goals however, incomplete removal of hexavalent chromium occurred at Well 5. ATEC returned to Well 5 for follow-up testing using higher ferrous doses in February 2026. With the higher ferrous doses, all treatment goals were met.
All testing was conducted using ferrous chloride as the chemical reductant. Logistical issues limited the October 2025 testing to only one media type – a manganese dioxide coated media marketed by ATEC as Pyrolox Advantage. However, during the February 2026 test it was possible to compare the performance of the Pyrolox media with a more conventional sand and anthracite filter media. Additional investigation into the settling characteristics of the backwash water was also conducted.
6.2 RESULTS
The complete pilot study report prepared by ATEC is included as Appendix A. The primary findings have been summarized below.
6.2.1 FERROUS DOSE AND CONTACT TIME
Testing at a constant ferrous dose of 1.0 mg/L at contact times of 1, 2, and 3 minutes showed that reaction times as low as 1 minute would be sufficient for near complete reduction of the chromium to occur. Conversely, holding the contact time constant at 2 minutes, ferrous doses of 1.5 and 2.5 mg/L were required for complete reduction to occur at Wells 12 and 5 respectively. 179
City of Los Banos August 2026
Cr(VI) Treatment Engineering Report
Section Six: Pilot Study Results
6-2
6.2.2 RE-OXIDATION
The study found that, to keep a free chlorine residual of at least 0.5 mg/L leaving the filter, 2.0 – 3.0 mg/L of sodium hypochlorite must be dosed upstream of the filter. This is roughly two to three times the dose the City is currently applying.
6.2.3 FILTRATION
Two media were evaluated during the February 2026 testing at Well 5: ATEC’s manganese dioxide coated media (Pyrolox Advantage) and sand with anthracite. Both media were able to achieve non-detectable levels of Cr(VI), Cr(T), and iron initially.
The Pyrolox media was able to operate at a higher filter loading rate, 8 gpm/ft2, compared to 5 gpm/ft2 for the sand and anthracite media. Additionally, the iron and chromium broke through the sand and anthracite filter quicker than the Pyrolox filter. The Pyrolox media is projected to require a smaller footprint than sand and anthracite as well as being the more water-efficient media.
The study found that, at a 8 gpm/ft2 filter loading rate, up to 95% removal of Cr(VI) can be achieved using the Pyrolox media. At a lower filter loading rate of 5 gpm/ft2, sand and anthracite achieves similar levels of removal.
6.2.4 IRON REMOVAL
As noted in Section 6.2.1, iron removal is an important operational performance indicator. Breakthrough of iron often occurs at the same time or shortly before breakthrough of chromium. Furthermore, iron levels can be reliably measured in the field using a handheld instrument and breakthrough of iron can potentially be monitored continuously using a turbidmeter. Whereas the operator has to wait days after collecting a sample to know what the chromium level was. Iron detections in the finished water suggest that iron precipitates are not being fully formed or removed, that the filter loading rate is too high, or that filter run times are too long. All the pilot filter runs during both phases of testing were either not taken to completion or were terminated based on iron breakthrough at ½ the MCL. Except for the October 2025 testing of Well 5, laboratory results later confirmed that Cr(VI) had not yet broken through at the time that iron levels in the filtered water began to rise.
The iron removal typically exceeded 96% during the filter runs. Once the filtered water iron levels did begin to rise, they rose to ½ of the iron MCL within approximately one hour. Overall, particularly during the second phase of testing at Well 5, iron concentrations approached the secondary MCL before Cr(VI) concentrations reached one-half of the primary MCL. This indicates that iron removal capacity, rather than Cr(VI) removal, was the limiting factor in achieving longer filter run times.
6.2.5 FILTER RUN LENGTH
Hydraulic loading rate, iron dosage, oxidant dosage, and contact time all contribute to the duration a filter can run prior to contaminant breakthrough. During operation, solids will accumulate throughout the filter bed causing increased head loss. After the pilot study, filter run times and production volumes were reported as unit filter run volumes (UFRVs), which establishes a uniform metric of efficiency based on volume of water produced per square foot of filter area.
The pilot conditions and resulting run lengths are summarized in Table 6 1. The results indicate that filter run lengths will be near 18 hours for a typical well. However, at wells with more challenging water quality, including wells with higher Cr(VI) levels (e.g. Well 5 and Well 14), much shorter filter runs – potentially as short as 4 hours, may be necessary.

While the pilot study was successful from the standpoint of the process being able to remove Cr(VI) from the water to below ½ of the MCL, some of the results raise questions and concerns that are unresolved.
These issues are discussed below.
6.3.1 MEDIA SELECTION
The relative performance of pyrolusite and sand and anthracite media were characterized during the second phase of the pilot study. However, the study’s budget and schedule did not allow any testing of ceramic media (Ceraflow-50, Wateropolis Corp). At least one study hints that ceramic media may perform better than pyrolusite in RCF treatment and that it could result in lower backwash flow rates and increased water recovery.
If the City does perform additional pilot testing, it is recommended that ceramic media be included.
6.3.2 SILICA ACCUMULATION
The silica levels at the City’s wells range from approximately 35 mg/L to 65 mg/L. Silica, when present in the water at high concentrations, can under some circumstances, form a coating on the surface of catalytic media such as manganese dioxide coated sand and pyrolusite. It is not known to what extent the catalytic characteristics of the manganese dioxide surface layer is affecting the RCF process. Since a critical step in the treatment process is reducing the Cr(VI) to Cr(III) and manganese dioxide facilitates oxidation, not reduction reactions, there may be no beneficial effect at all. However, if the active surface of the media is helping the RCF process and silica does build up on the media, performance could degrade over time.
The test duration during the pilot study was not long enough for silica fouling issues to become apparent.
The filters might need to run for months before an issue develops. When the Well 9 treatment plant is operational, raw and treated water silica levels should be compared to see if any silica removal by the media is taking place.
6.3.3 OPERATION FOLLOWING STANDBY PERIODS
A standby operation test was conducted to evaluate the performance of the filters when restarted following a backwash and an approximately 16-hour long filter shutdown. Following the shutdown period, approximately ½ of the filter volume was flushed to waste prior to sampling the water for chromium. The Pyrolox Advantage media produced a post shutdown hexavalent chromium concentration of 220 ug/L.
The sand and anthracite media post-filter level was 13 ug/L. This shows that elevated chromium concentrations can occur following extended periods of non-operation. Since the 220 ug/L concentration is at least four times the raw water concentration, some mechanism other than re-oxidation of Cr(VI) to Cr(III) must be involved.
Based on those findings, ATEC recommends flushing one complete system volume, including contact tanks and associated process piping, to waste before returning to normal operations after extended standby periods. However, this mitigation measure was not proven during the study to confirm its effectiveness. Furthermore, even if the 1 BV flush-to-waste is successful, it still represents additional tens of thousands of gallons of wasted water any time one of the treatment plants have been off-line. Specific questions that still need to be answered include:
182
City of Los Banos August 2026
Cr(VI) Treatment Engineering Report
Section Six: Pilot Study Results
6-2
1. What is the mechanism by which chromium levels are so significantly concentrated?
2. Is this behavior consistent and repeatable?
3. How long can the filters be off-line prior to this issue developing?
4. What is the minimum duration and volume of flushing necessary to mitigate the chromium spike? If the City goes ahead with constructing a full-scale treatment plant at Well 9 as the next step in the program, that treatment plant should be designed to accommodate frequent backwashing and flush-towaste operation while this issue is being investigated. Well 9 is a good candidate for this testing as there are large sewer and storm drain pipelines next to the site and the well is equipped with a VFD that should permit some tests to be conducted at reduced flow rates.
6.3.4 OVERALL WATER RECOVERY
Table 6-2 below summarizes the water production efficiency and waste volumes predicted by the pilot study. The filter run lengths and corresponding Unit Filter Run Volumes (UFRVs) achieved were relatively low, driven by early iron breakthrough in all cases. Well 5 is projected to have a particularly low recovery of 96% - meaning that 4% of the water produced by the well goes to waste. However, the issue of Chromium spikes following standby periods has not yet been resolved, and the potential solution proposed by ATEC, flushing one entire system volume to waste prior to discharging water into the distribution system, would result in an additional approximately 12,000 gallons of waste every time the well is restarted after an inactive period – further reducing water recovery.

6.3.5 BACKWASH RESIDUALS
During the second phase of the pilot study, washwater from each filter column was discharged to a 5- gallon bucket and immediately transferred to Imhoff cones where settling characteristics could be observed. It was then left to rest for approximately 12 hours, allowing a solids blanket to form at the bottom.
Laboratory water quality tests for Cr(T), arsenic, TSS, and BOD were conducted on mixed washwater, decant water, and settled solids. Samples of the sludge were subjected to TTLC and WET tests and arsenic and chromium were both well below regulatory limits. Testing for TTLC compliance was not conducted.
The pilot test showed that the process generated readily settleable backwash residuals, with the pilot plant operator reporting that clarification at the top of the column was apparent almost at once after the backwash water was transferred to the cones. However, the sludge remaining after four hours of settling remained relatively bulky, producing a sludge blanket that represented 17% of the total backwash volume following operation with an iron dose of 2.5 mg/L. That percentage increased to 30% of the total volume when the iron dosage was increased to 3.5 mg/L. This rapid build-up of sludge would hinder a backwash reclaim process.

7 RECOMMENDATIONS
7.1 FILTRATION SYSTEM
Although the pilot filter was successfully run at loading rates as high as 8 gpm/ft2, it is recommended that the filters be designed for operation at no greater than 7 gpm/ft2 at the Well 9 treatment plant. The filter loading rate could be re-visited after the Well 9 treatment plant is operational, and the remaining issues identified in the pilot study are resolved.
Because Well 9 has access to a relatively large sewer pipeline, either a modular system or horizontal multi-cell filters could be used, however, a modular system with smaller filter vessels similar to those offered by ATEC is recommended for the following reasons:
1. This treatment plant is intended to serve as a full-scale pilot plant that will be used to work through remaining operational issues. Operation at reduced flow rates with a significant number of vessels off-line may be advantageous. The higher filter vessel count that modular systems provide would facilitate operation at a range of flow rates while maintaining a targeted hydraulic loading rate.
2. ATEC performed the pilot study that will serve as the basis of the treatment plant design parameters including iron dose, hydraulic loading rate, and filter run length. The City could consider placing a performance guarantee in the procurement specification that would include some remedy (possibly a monetary rebate or installation of additional vessels) if the plant is not operable using the parameters recommended in the pilot study report. Even if a formal performance guarantee is not included, it is probable that ATEC would be more motivated to help the City with troubleshooting compared to another supplier that was only relying on testing performed by a third party competitor.
Depending on what kind of experience the City has with the modular system at Well 9, the remaining treatment plants with large-diameter sewers nearby could use either modular or horizontal filters. It may be possible to develop an approach within the City’s procurement rules that allows competitive bidding between the two filter configurations despite their differences. For the purposes of estimating the footprint of the treatment plants in Section 8 and estimating the costs in Section 10, modular systems loaded with Pyrolusite filter media have been assumed.
At wells with limited sewer capacity and insufficient room for a backwash equalization tank, the horizontal systems will not work and modular filter system must be used.
Table 7-1 summarizes the total filter area needed and the corresponding number of 4’ modular tanks that would be required at each treatment plant.

7.2 CHEMICAL SYSTEMS
The predicted chemical doses and usage rates for each of the treatment plants are summarized in Table 7-2. The estimated ferrous dose at each well assumes that ferrous dose is proportional to the concentration of Cr(VI). The doses needed during the pilot study at Wells 5 and 12 were then used to interpolate the values at the other wells. Because these estimates are based on the average annual production from the wells, the estimated daily use values will be significantly higher during the summer months.

The level of fluoride in the water is not expected to affect the performance of RCF treatment. Therefore, if the City prefers, the existing fluoridation system can remain in place, provided the sodium fluoride is well mixed with the water prior to ferrous chloride addition. Alternatively, the sodium fluoride storage and feed system can be combined in the same general enclosure area as the two other chemical feed systems. The preliminary site plans in Section 8 assume that the sodium fluoride storage and feed system stays in the building.
Ferrous chloride of between 25 and 30% concentration should be used as the reductant. Currently, only drums and 275-gallon intermediate bulk containers (IBCs), also referred to as “totes,” are available from the two major chemical suppliers: Brenntag and Univar. It is estimated that, if all wells are treated, the City would use almost 50,000 gallons of ferrous chloride per year. Chemical purchased in IBCs has been quoted to be 30% less expensive than chemical purchased in drums – an estimated $155,000 annual cost savings. It is recommended that the ferrous chloride be purchased in IBCs. To simplify the logistics of changing out IBCs during chemical deliveries, two IBCs should be available to supply the dosing pumps.
Sodium hypochlorite use will roughly double to triple at wells being treated with RCF. If all thirteen wells are treated, the City would use almost 87,000 gallons of 12.5% sodium hypochlorite per year. Sodium hypochlorite is available in bulk (tanker truck) and mini-bulk deliveries (smaller than full tanker loads). The cost of chemical purchased as mini bulk deliveries into 500-gallon storage tanks has been quoted by the City’s chemical supplier to be less than one half of the cost of sodium hypochlorite purchased in drums – an estimated $435,000 annual cost savings. It is recommended that the City use a mini-bulk delivery program incorporating 500 – 1,500 gallon storage tanks, depending on the capacity of the well.
Peristaltic dosing pumps are recommended. Peristaltic pumps manage off-gassing chemicals such as sodium hypochlorite well. Additionally, because peristaltic pumps have enough suction lift, they can pull chemical from the top of the sodium hypochlorite storage tank . Pulling the chemical from the top of the tank allows double wall tanks to be used with no further secondary containment required.
There are several alternatives for configuring the chemical storage and feed area. The area needs to be well ventilated, preferably shaded, accessible for chemical delivery trucks and for handling the IBCs, and preferably should provide an added barrier to vandalism. Separate secondary containment must be provided for each chemical. If peristaltic pumps are used to draw sodium hypochlorite out of the top of the tank, a double wall tank will satisfy the secondary containment requirement. The ferrous chloride IBC containers can be placed on top of spill pallets. The lowest cost alternative for the enclosure would be chain link fence with privacy slats and a simple sloped roof. The fence “walls” would include gates where necessary to access the enclosure for chemical deliveries. More robust containment enclosures, incorporating concrete containment curbs to separate the chemical storage and feed systems are often used at larger facilities.
7.3 BACKWASH WATER MANAGEMENT
The backwash water management approach will need to vary from well to well based on the site constraints. At wells where direct discharge to the sewer is possible, this is recommended as the simplest and lowest cost means of disposal. Where necessary, small backwash equalization tanks should be used to reduce the flow rate into the sewer. Even though some sites are a long distance away from the nearest sewer (e.g. Well 11), it is recommended that the nearest sewer be extended out to the well 189

instead of using backwash water reclaim. Installation of backwash water reclaim and sludge dewatering systems is not recommended at any of the wells.
7.4 CONTROLS
Because this first treatment plant with be used as a pilot project, it will be important to record and trend data from the instruments, to have easily configurable alarms, and to provide flexibility in operations. It is therefore recommended that the treatment plant incorporate one of these two control approaches: the filter system control panel should utilize a fully-functional PLC that would be used to control and monitor both on-skid and off-skid treatment plant functions or, the site PLC should be upgraded and interfaced with an I/O panel included with the filtration system.

8 TREATMENT PLANT SITING
8.1 SITE LAYOUT CONSIDERATIONS
Several of the City’s wells are found on sites with limited available space for the addition of RCF treatment. Additionally, some of the sites are several hundred to more than one thousand feet away from the nearest sewer. The following site plans were developed with the primary purposes of determining if there is sufficient space at each of the sites for the treatment systems and determining the most feasible means of connecting the sites to a sanitary sewer. Showing an arrangement that supports access to the well for servicing by a well rig was also of primary importance. These schematic site plans reflect only one of several arrangements that are possible and optimization of the layouts is beyond the scope of this report.
The site layouts illustrate a mix of modular filtration systems and horizontal multi-cell filter systems. As illustrated in Figure 8-10, the footprint for the two systems is similar, and it does not appear that footprint will be the deciding factor when selecting between the two alternatives at any of the sites. All site plan figures can be found at the end of Section 8.
8.2 PRELIMINARY TREATMENT PLANT SITING
8.2.1 CENTRALIZED TREATMENT OF WELLS 1, 2, AND 3
Wells 1, 2, and 3 are located within the City’s Corporation Yard on City-owned property. Given the proximity of the wells to one another, centralized treatment is recommended. The design flow rate produced by the three wells is 2,750 gpm. There does not appear to be any location on the site where there is enough open space for construction of the treatment plant. Demolition of some existing facilities will be required. The layout in Figure 8-1 assumes that the sand and gravel storage area at the southeastern corner of the yard will be moved elsewhere to make room for the treatment plant.
Based on the City’s Sewer Map, the nearest sewer to the proposed treatment plant is 6-inches and located in Madison Avenue. However, the City should verify that a sewer service does not already extend onto the site. The sewer is too small to accept the 250-gpm backwash flow rate from a modular system directly. A bolted steel equalization tank with a capacity of 80,000 gallons, twice the volume of a single backwash cycle, is shown.
8.2.2 WELL 5
Well 5 is located at the corner of State Route 165 and East B Street on City-owned property. The parcel appears to extend approximately 100 feet to the west of the well building. This irregularly shaped expansion area would provide enough space for construction of the treatment plant, including a backwash equalization tank, if one is necessary. There is an 8-inch sewer in B-street just south of the site and a larger 12-inch sewer in State Route 165 to the west. Refer to Figure 8-2. A modular filter system could backwash directly into the 12-inch sewer. However, an equalization tank would be needed for a horizontal filter system.
If for some reason the area west of the well building is not useable, there is a City-owned property on the south side of East B Street directly across from the well that is currently used for a storm water pumping station. It appears that the treatment plant would fit on this site without interfering with the storm water infrastructure. Well 5 has been identified as the potential location of a centralized treatment plant treating as many as four wells.

8.2.3 CENTRALIZED TREATMENT OF WELLS 5, 7,9, 13 AT WELL 5 Wells 7, 9, and 13 are located within a 1/2-mile radius of Well 5 (see Figure 8-4). Centralized treatment of Well 5 with one or more of these wells was considered. There may be enough room on the parcel south of Well 5 for a centralized treatment plant (see Figure 8-3). However, the layout of existing storm drainage facilities on the site needs to be better understood to confirm this. Splitting the treatment plant facilities between the north and south parcels is also a possibility. Well 13 is particularly space constrained and siting an RCF treatment plant at the well site will be challenging. Well 7 is currently on standby because of high uranium levels. Well 5 has relatively low levels of uranium. Centralized treatment of these two wells would allow the City to return Well 7 to active status, provided it was always operated at the same time as Well 5.
8.2.4 WELL 6
Well 6 is located at the corner of W J Street and Colorado Avenue on the east side of the airport. City staff report that there are no known height restrictions or other Federal Aviation Administration (FAA) rules that would hinder construction of the treatment plant near the runway. Assuming that to be the case, there is a large open field surrounding the well that would accommodate a large treatment plant at the site (see Figure 8-5).
The nearest sewer is in Colorado Ave and J Street. The sewer is 6-inches in diameter. There is also a 12- inch sewer approximately 1,500 feet to the south, near the southern end of the runway, just north of Pacheco Road. Ther 12-inch sewer should be adequate for direct discharge of backwash water from a modular or horizontal filter system. A backwash equalization tank would be needed for either modular or horizontal filter systems to discharge into the 6-inch sewer.
8.2.5 CENTRALIZED TREATMENT OF WELL 12 AT WELL 6
Wells 12 is located within a 1/2-mile radius of Well 6. Centralized treatment of Well 6 with Well 12 was considered (see Figure 8-6). The Well 12 site is particularly space constrained, and it may be necessary to treat it at an off-site location. Centralized treatment at Well 6 would be a good location. If horizontal filters are used at the centralized treatment plant, it would likely b necessary to use at least two vessels with 4 cells each to keep backwash water flow rates low enough for direct discharge to the 12-inch sewer.
8.2.6 CENTRALIZED TREATMENT OF WELLS 6, 12, 15 AT WELL 6 Connecting Well 15 to the Well 6 Treatment Plant would require an approximately 1-1/4 mile transmission pipeline (see Figure 8-8). However, if for some reason discharging backwash water into the sewer force main at Well 15 is not possible, this may be the best alternative remaining (see Figure 8-7).
8.2.7 WELL 7
Well 7 is out of service due to elevated levels of uranium. There is unlikely to be a scenario where Well 7 is treated by itself. However, for completeness, a conceptual site plan for a Well 7 treatment plant has been provided (see Figure 8-9). Treatment of Well 7 would require demolishing the horseshoe pits north of the existing well. A 12-inch sewer is located a short distance south of the well at the intersection of San Luis Street and Miller Lane. It is proposed that Well 7 be treated at the Well 5 Treatment Plant where blending can be used to mitigate the uranium.

8.2.8 WELL 9
Well 9 is located east of Willmot Avenue and Toscano Court near residential neighborhoods. The Well 9 site is large enough to accommodate a treatment plant using either modular or horizontal filters. Figure 8-10 illustrates a possible layout showing both types of filtration system. The footprints of the two systems are similar.
There are 18-inch storm drain and sanitary sewer pipelines within Willmott Avenue making this site a good candidate for the first full-scale treatment plant. No backwash equalization tank will be needed.
8.2.9 WELL 10
Well 10 is located on the east side of Place Road, approximately 400 feet north of St. Patrick’s Road. A 27- inch sewer is located in front of the site within Place Road. While the site plan shows that the proposed treatment plant will, in theory, fit on the existing site, it is very tight and detailed design may reveal constraints that will require expanding the site onto privately owned land to the north and/or east (see Figure 8-11).
The Ward Road Tank is located approximately ½ mile southeast of the well site. Because Well 10 supplies the Ward Road Tank directly, with no services off the transmission pipeline, the treatment plant can be located at the tank site or anywhere along the transmission pipeline alignment which runs along Place Road (see Figure 8-13). A separate site plan illustrates how a treatment plant would fit at the tank site (see Figure 8-12). However, there is no sewer service at the tank site. A new sewer would need be constructed north on Ward Road to an existing 12-inch sewer near the intersection of Ward Road and Gilbert Gonzales Drive.
8.2.10 WELL 11
There appears to be just enough space to construct a treatment plant at the existing site, however, it is possible that detailed design will find constraints resulting in the need to expand the site (see Figure 8- 14). The most significant obstacle to constructing a treatment plant at the well is the lack of a nearby sewer. The nearest sewers are approximately 1,500 feet west or 1,000 feet east of the site. The alignment in both directions would be along HWY 152.
8.2.11 WELL 12
Well 12 is located in a residential neighborhood on the corner of I Street and Birch Avenue. The site appears to have enough space for the proposed treatment plant (see Figure 8-15). However, trees obscure much of the site on aerial images and a topographic survey may reveal that a treatment plant will not fit on the site. Eight-inch sewers are located at Daffodil Street to the west and Birch Avenue to the east. A 12-inch sewer is located at I Street to the south. There is not enough room for a backwash equalization tank at the site. It is possible that a modular filtration system could discharge directly into one of the 8-inch sewers but connection to the 12-inch sewer is recommended.
8.2.12 WELL 13
Well 13 is located on D Street, approximately 400 feet west of Mercy Springs Road. The site appears to have adequate space for the proposed filtration system and chemical enclosure, particularly if the west fence line is shifted towards the road (see Figure 8-16). However, there is insufficient space to accommodate an adequately sized backwash equalization tank. As a result, discharging the backwash water into the existing 6-inch sewer line along the southern property boundary is not an option. 193

Section Eight: Treatment Plant Siting
8-4
A 400-foot sewer pipeline would need to be constructed to convey backwash water from the treatment site to the nearest 12-inch sewer main.
8.2.13 WELL 14
Well 14 is located at the northeast corner of Cabernet Street and Birchwood Avenue. The existing well building is situated on a relatively small parcel next to Vineyards Basin Park. To accommodate the proposed treatment facilities, approximately 0.15 acres of park space would need to be allocated by the City (see Figure 8-17). However, a 10-inch sanitary sewer is located approximately 80 feet from the proposed treatment plant.
8.2.14 WELL 15
Well 15 is located just outside City limits along Badger Flat Road. The site appears to have enough available space for treatment. However, there is no gravity sewer pipeline in the area surrounding the well. There is a 12-inch sewer force main in Badger Flat Road. It has been assumed that a pumping station would be used to discharge backwash water into the force main. 194

Section Nine: Impact on Water Operations
9-1
9 IMPACT ON WATER OPERATIONS
9.1 LOST PRODUCTION CAPACITY
Installation of a filtration system downstream of the well pumps will result in added pressure loss. Typical filter pressure losses range from 2 – 10 psi depending on the hydraulic loading rate, underdrain configuration, whether static chemical mixers are used, and other factors. The result is that the wells are pumping against more back pressure than they do currently and will therefore produce less flow at the same pump speed. It might be possible to compensate for the pressure loss at wells with pumps equipped with VFDs. The only way to recover the lost production capacity at wells with constant speed pumps is to upgrade the pump.
Pump curves were not available to estimate the reduction in pumping capacity at any of the wells. The impact on production is typically greatest at pumps discharging into storage tanks, since the relative increase in pump discharge pressure is greater than at pumps sized to discharge directly into the distribution system. Provided there is a functioning pressure gauge or transmitter at the well, a field test can be conducted to better estimate the reduction in flow. This would involve recording the current flow rate and discharge pressure and then partially closing a downstream isolation valve until the discharge pressure increases by 5 psi. Once the pressure has stabilized, record the new flow rate.
9.2 OPERATOR CERTIFICATIONS
It is likely that DDW will classify the treatment plants as T2 facilities. The Chief Operator would need to have a certification no less than T2 and all Shift Operators would have to hold T1 certifications. Some of the City’s operators possess T2 certifications.
9.3 STAFFING
More water treatment and water distribution operators will likely be required to appropriately manage and operate the new treatment plants. Treatment plant operational activities that require routine attention include, but are not limited to:
1. General maintenance, including cleaning and inspecting valves, filters, instruments, and chemical systems for proper function and repairing equipment as necessary
2. Performing field chlorine residual and iron testing
3. Logging totalized flow, and tracking pressure loss across the filters
4. Adjusting chemical metering pump settings
5. Collecting grab samples from the raw and treated water for laboratory analysis. Testing of the backwash water may also be required
6. Chemical handling. There will now be three chemicals used at each well. Sodium hypochlorite usage is expected to go up significantly with the addition of treatment and the water will now be dosed with ferrous chloride. Chemical deliveries will be more frequent than they are currently
7. Continuous water quality analyzers will need periodic calibration and reagent replacement
9.4 CHEMICALS
Because bulk chemical deliveries into storage tanks and intermediate bulk containers (IBC) would be used, greater attention will need to be paid to the timing of chemical orders and deliveries. Whereas the 30-gallon drums the City currently relies on can be stockpiled and easily moved between sites, it will be 213
City of Los Banos August 2026
Cr(VI) Treatment Engineering Report
Section Nine: Impact on Water Operations
9-2
difficult to do so with 275-gallon IBC totes. Bulk deliveries would need to be coordinated between the sites to minimize delivery charges.
9.5 WELL IN-SERVICE PRIORITIZATION
Filtration treatment plants work best when they experience uninterrupted operation at constant flow rates. The City may need to change current well prioritization practices to avoid frequent well pump starts and stops and to minimize use of wells that are more challenging to treat or where disposal of backwash water is more problematic.

10.2 O&M COST ESTIMATES
The primary sources of operating cost increase associated with RCF treatment are:
1. Purchasing ferrous sulfate
2. Purchasing additional sodium hypochlorite
3. Labor
4. Laboratory
5. Added pumping power
10.2.1 CHEMICALS
In July 2026 Brenntag quoted the City $10/gallon for 28 – 30% ferrous chloride delivered in 250-gallon IBC/totes. It is estimated that the City will use 54,000 gallons of chemical annually. The estimated annual cost of purchasing ferrous sulfate is therefore $540,000.
In July 2026 Brenntag quoted the City $3.70/gallon for 12.5% sodium hypochlorite delivered in mini-bulk loads. It is estimated that the City will use 141,000 gallons of chemical annually. The estimated annual cost of purchasing sodium hypochlorite is therefore $540,000. Some of this cost is offset by the City’s current cost of purchasing sodium hypochlorite in drums at $8.71/gallon which, assuming a current dose of 1 mg/L, is estimated to be $189,000. The estimated annual increase in cost of purchasing sodium hypochlorite is therefore $351,000
Once all treatment plants are operational, it is estimated that the City will spend an additional $891,000 on chemicals annually.
10.2.2 LABOR
The added labor needed to run the treatment plants can be best judged by the City’s operations staff.
Once the treatment plants are all in service and startup issues are resolved, it is reasonable to assume that operations staff will need to spend at least an average of one hour per day at each treatment plant, which is 4,730 hours per year.
10.2.3 LABORATORY
There is no reliable field test for hexavalent or total chromium. The only water to confirm that the treatment plants are effectively removing the hexavalent chromium from the water is to send samples of the water into a laboratory for analysis. Assuming that each well needs to be sampled quarterly and each treatment plant monthly; and assuming $85/sample, the annual cost of laboratory services would be $17,680.
10.2.4 POWER
The City’s utility costs will go up as a result of needing to pump the water against approximately 5 psi of added back pressure. The cost of additional power is estimated to be roughly $25,000 per year. 217

FROM: Nirorn Than, City Manager
Mary F. Lerner, City Attorney
DATE: September 2, 2026
TYPE OF REPORT: Agenda Item
SUBJECT: City Council Vacancy – District 1
______________________________________________________________________ Recommendation:
Adopt a resolution calling a special election to place the District 1 City Council vacancy on the March 2, 2027 General Election ballot and consolidating the election with the County of Merced general election.
Discussion:
Former District 1 Council Member Mitzy Perez resigned from her council seat effective August 31, 2026. As a result, a mid-term vacancy has occurred for the District 1 City Council seat.
Pursuant to Government Code §36512(b), if a City Council Member vacancy occurs, the City Council must, within sixty (60) days from the date of the vacancy (specifically, by October 30, 2026), either fill the vacancy by appointment or by calling a special election (which can run concurrent with a general election/be subsumed by the general election) to fill the vacancy.
However, there are limits to the appointment power. The City Council cannot fill a vacant seat by appointment if that appointment would result in a majority of the City Council having been appointed, not elected. In that case, the vacancy must be filled by election (Government Code § 36512(d)). Currently, Council member Marcus Chavez and Council member Regio Llamas hold appointed, rather than elected, positions on City Council. 221
ITEM 8
Since Government Code section 36512(d) provides that a majority of council members cannot be appointed, the only option currently available to the City Council is to fill the vacant District 1 seat by special election. That election will be held “on the next regularly established election date not less than 114 days from the call of the special election.” Based upon the 114-day requirement, the next eligible regular election date is March 2, 2027. (See, California Elections Code section 1000(b) which provides “The established election dates are as follows:…The First Tuesday after the first Monday in March of each odd-numbered year.”) Since the election date is March 2, 2027, the County Registrar of Voters has indicated that the candidate filing period is from November 7, 2026, until December 2, 2026.
A person elected to fill the District 1 vacancy would hold office until the general election on November 7, 2028. The time period between the special election on March 2, 2027 and the general election on November 7, 2028 is the unexpired term of the former incumbent.
Fiscal Impact:
The City would be responsible for the cost of a special election. The expenditure for this election will require a budget amendment to the Fiscal Year 2026 – 2027. Staff intend to bring this amendment to council for approval at Mid-Year. A special election is estimated by the County Elections Office to cost $65,590.55 plus or minus 10%.

City Manager
FROM: Brandon Dorenbush, Fire Chief
DATE: September 2, 2026
TYPE OF REPORT: Agenda Item
SUBJECT: Approve Purchase Agreements with Burtons Fire Apparatus for a Purchase of Two Type I Rosenbauer Fire Engines and Approve a Budget Amendment in Measure P Fund for Fiscal Year 2026-2027.
______________________________________________________________________ Recommendation:
Staff recommends that the City Council adopt a resolution:
1. Approving purchase agreements with Burtons Fire Apparatus for the purchase of two (2) stock Rosenbauer Type I fire engines;
2. Authorizing the City Manager, or designee, to execute the purchase agreements and any related documents necessary to carry out the intent of this Resolution;
3. Approving a budget amendment increasing expenditures in Measure P Fire line item 238-422-100-755 by $1,329,615.39; and approving a budget amendment increasing revenue in line item 238-000-390-010 to recognize the estimated $83,000 trade-in value.
Background:
Two of the Department's current fire engines were placed in service in 2004 and 2008.
Over the years, these apparatuses have been essential components of the firefighting fleet, responding to numerous emergencies and helping ensure the safety of our community. However, as these engines have aged, maintenance and repair costs have increased significantly, particularly over the past two years. In addition, the older 225
ITEM 9
apparatus is becoming less reliable and costly to maintain. The replacement of these engines will improve fleet reliability, reduce maintenance expenses, and ensure firefighters have access to safe and dependable equipment for emergency response.
Discussion:
In Fiscal Year 2026-27, funding was included in the Fire Department budget for the purchase of additional fire equipment to enhance emergency response capabilities and support the Department's fleet replacement program. This budget is specifically for a minipumper First Out Utility Truck (FOUT). This truck availability is better than the Type I engine and is typically cheaper. As our need is immediate, staff has determined that it is a great stop-gap secondary type engine to keep up with service demand.
Recently, an opportunity has become available to acquire two fully built, in-stock Rosenbauer Type I fire engines at a significant discount, allowing the Department to address multiple apparatus replacement needs while maximizing the value of available funding. Purchasing these two engines would substantially reduce delivery times, address both current and future fleet replacement needs, and ensure reliable operational readiness for emergency response.
The department plans to trade in two older command units and two engines and apply FY 2026-27 budgeted funds toward the purchase of these two new engines instead. This approach will help offset replacement costs, enabling the department to update equipment while remaining fiscally responsible.
The procurement of the fire engines was conducted through Sourcewell, a cooperative purchasing organization that competitively solicits and awards contracts on behalf of participating public agencies. Utilizing the Sourcewell cooperative purchasing contract allowed the City to procure fire engines through an established competitive procurement process, consistent with applicable purchasing requirements and the City’s procurement policies.
In addition, acquiring the apparatus now would enhance fleet reliability, reduce maintenance and repair costs associated with aging equipment, and provide continued support for effective emergency service delivery to the community.
The requested budget amendment includes the estimate cost of upfitting the two new engines with emergency lighting, radio and communications equipment, tools and equipment, and other essential soft and hard assets. Vehicles are immediately available and can be purchased and delivered prior to November.
This item has been reviewed by the Measure P Oversight Committee on 8/28/2026. 226
Fiscal Impact:
The total purchase cost is $1,739,615.39, with an additional $100,000 in estimated upfitting costs, for a total project cost of $1,839,615.39. The Fiscal Year 2026-27 Budget includes appropriations for an engine-type purchase, and those funds will be reclassified to partially offset this expenditure. As a result, a budget amendment is required to increase appropriations in the Measure P Fire line item 238-422-100-755 in the amount of $1,329,615.39.
Additionally, the City is expected to receive approximately $83,000 in trade-in revenue.
Therefore, a budget amendment is needed to increase revenue in line item 238-000-390- 010 by the estimated trade-in amount.
The net fiscal impact of the budget amendments is $1,246,615.39.

TO: Mayors, Council Members, City Clerks, and City Managers RE: DESIGNATION OF VOTING DELEGATES AND ALTERNATES
League of California Cities Annual Conference and Expo, Sept. 23-25, 2026 Anaheim Convention Center
Every year, the League of California Cities convenes a member-driven General Assembly at the Cal Cities Annual Conference and Expo. The General Assembly is an important opportunity where city officials can directly participate in the development of Cal Cities policy.
Taking place on Friday, Sept. 25, 2026 the General Assembly is comprised of voting delegates appointed by each member city; every city has one voting delegate. Your appointed voting delegate plays an important role during the General Assembly by representing your city and voting on resolutions.
To cast a vote during the General Assembly, your city must designate a voting delegate and up to two alternate voting delegates, one of whom may vote if the designated voting delegate is unable to serve in that capacity. Voting delegates may either be an elected or appointed official.
Action by Council Required. Consistent with Cal Cities bylaws, a city’s voting delegate and up to two alternates must be designated by the city council. Please note that designating the voting delegate and alternates must be done by city council action and cannot be accomplished by individual action of the mayor or city manager alone.
Following council action, please submit your city’s delegates through the online submission portal by Tuesday, Sept. 1, 2026. When completing the Voting Delegate submission form, you will be asked to attest that council action was taken. You will need to be signed in to your My Cal Cities account when submitting the form.
Submitting your voting delegate form by the deadline will allow us time to establish voting delegate/alternate records prior to the conference and provide pre-conference communications with voting delegates.
Conference Registration Required. The voting delegate and alternates must be registered to attend the conference. They need not register for the entire conference; they may register for Friday only. Conference registration opens June 2.
For a city to cast a vote, one voter must be present at the General Assembly and in possession of the voting delegate card and voting tool. Voting delegates and Council Action Advised by September 1, 2026
239
alternates need to pick up their conference badges before signing in and picking up the voting delegate card at the voting delegate desk. This will enable them to receive the special sticker on their name badges that will admit the voting delegate into the voting area during the General Assembly.
Please view Cal Cities’ event and meeting policy in advance of the conference.
Transferring Voting Card to Non-Designated Individuals Not Allowed. The voting delegate card may be transferred freely between the voting delegate and alternates, but only between the voting delegate and alternates. If the voting delegate and alternates find themselves unable to attend the General Assembly, they may not transfer the voting card to another city official.
Seating Protocol during General Assembly. At the General Assembly, individuals with a voting card will sit in a designated area. Admission to the voting area will be limited to the individual in possession of the voting card and with a special sticker on their name badge identifying them as a voting delegate.
The voting delegate desk, located in the conference registration area of the Long Beach Convention Center in Long Beach, will be open at the following times: Wednesday, Sept. 23, 8:00 a.m.-6:00 p.m. and Thursday, Sept. 24, 7:30 a.m.-4:00 p.m. On Friday, Sept. 25, the voting delegate desk will be open at the General Assembly, starting at 7:30 a.m., but will be closed during roll calls and voting.
The voting procedures that will be used at the conference are attached to this memo.
Please share these procedures and this memo with your council and especially with the individuals that your council designates as your city’s voting delegate and alternates.
Once again, thank you for submitting your voting delegate and alternates by Tuesday, Sept. 1. If you have questions, please contact Zach Seals at [email protected].

1. One City One Vote. Each member city has a right to cast one vote on matters pertaining to Cal Cities policy.
2. Designating a City Voting Representative. Prior to the Cal Cities Annual Conference and Expo, each city council may designate a voting delegate and up to two alternates; these individuals are identified on the voting delegate form provided to the Cal Cities Credentials Committee.
3. Registering with the Credentials Committee. The voting delegate, or alternates, may pick up the city's voting card at the voting delegate desk in the conference registration area. Voting delegates and alternates must sign in at the voting delegate desk. Here they will receive a special sticker on their name badge and thus be admitted to the voting area at the General Assembly.
4. Signing Initiated Resolution Petitions. Only those individuals who are voting delegates (or alternates), and who have picked up their city’s voting card by providing a signature to the credentials committee at the voting delegate desk, may sign petitions to initiate a resolution.
5. Voting. To cast the city's vote, a city official must have in their possession the city's voting card and voting tool; and be registered with the credentials committee. The voting card may be transferred freely between the voting delegate and alternates but may not be transferred to another city official who is neither a voting delegate nor alternate.
6. Voting Area at General Assembly. At the General Assembly, individuals with a voting card will sit in a designated area. Admission to the voting area will be limited to the individual in possession of the voting card and with a special sticker on their name badge identifying them as a voting delegate.
7. Resolving Disputes. In case of dispute, the credentials committee will determine the validity of signatures on petitioned resolutions and the right of a city official to vote at the General Assembly.

Sixty days before the
Annual Conference
and Expo, Cal Cities
members may submit
policy proposals on
issues of importance
to cities. The resolution must
have the concurrence of at least
five additional member cities or
individual members.
How it works: Cal Cities
Resolutions and the General Assembly
General Assembly
General Resolutions Policy Committees
Developing League of California Cities policy is a dynamic process that engages a wide range of members to ensure Cal Cities represents cities with one voice. These policies directly guide Cal Cities’ advocacy to promote local decision-making, and lobby against statewide policies that erode local control.
The resolutions process and General Assembly is one way that city officials can directly participate in the development of Cal Cities policy. If a resolution is approved at the General Assembly, it becomes official Cal Cities policy. Here’s how resolutions and the General Assembly work.
The petitioned
resolution is an
alternate method
to introduce policy
proposals during
the annual conference. The
petition must be signed by
voting delegates from 10% of
member cities, and submitted to
the Cal Cities President at least
24 hours before the beginning
of the General Assembly.
Petitioned Resolutions
The Cal Cities
President assigns
general resolutions
to policy committees
where members
review, debate, and recommend
positions for each policy proposal.
Recommendations are forwarded
to the Resolutions Committee.
Who’s who
The Resolutions Committee
includes representatives
from each Cal Cities
diversity caucus, regional
division, municipal
department, and policy
committee, as well as
individuals appointed by
the Cal Cities president.
Voting delegates
are appointed by each
member city; every city
has one voting delegate.
The General Assembly is a
meeting of the collective
body of all voting
delegates —one from
every member city.
Seven policy committees
meet throughout the year
to review and recommend
positions to take on bills
and regulatory proposals.
Policy committees include
members from each Cal
Cities diversity caucus,
regional division, and
municipal department,
as well as individuals
appointed by the Cal
Cities president.
During the General Assembly, voting delegates
debate and consider general and petitioned
resolutions forwarded by the Resolutions
Committee. Potential Cal Cities bylaws
amendments are also considered at this meeting.
Cal Cities policy
development is a memberinformed process,
grounded in the voices and
experiences of city officials
throughout the state.

Resolutions Committee
The Resolutions
Committee considers
all resolutions. General
Resolutions approved1 by
either a policy committee
or the Resolutions Committee are next
considered by the General Assembly.
General resolutions not approved, or
referred for further study by both a
policy committee and the Resolutions
Committee do not go to the General
Assembly. All Petitioned Resolutions
are considered by the General
Assembly, unless disqualified.2
During the Annual Conference and Expo
1 The Resolution Committee can amend a general resolution prior to sending it to the General Assembly. 2 Petitioned Resolutions may be disqualified by the Resolutions Committee according to Cal Cities Bylaws Article VI. Sec. 5(f). 242
