FISCAL IMPACT:
The proposed construction contract with Consolidated is for $ 168, 98, with a requested construction contingency of $ 33, 798. The total construction budget for the Project is $ 202, 786. Sufficient funds were allocated in the adopted Fiscal Year ( FY) 2025-6 budget to CIP PS 26-3 to fund the construction contract and requested contingency; therefore, no budget amendment is needed.

IMPROVEMENTS, CIP PW 2O- 16
RECOMMENDATION: Adopt Resolution to Approve a Professional Services Agreement with Pacific Advanced Civil Engineering,
Inc. (PACE) for Engineering Consulting Services for
Groundwater Treatment Improvements, CIP PW 2O16
SUMMARY:
Perfluoroalkyl and polyfluoroalkyl substances ( PFAS) have been detected in the City' s groundwater supply at concentrations exceeding State and Federal drinking water standards. Additional treatment for PFAS at the Louise Avenue Water Treatment Facility ( LAWTF) is needed to protect public health and maintain regulatory compliance.
Staff requests that the City Council approve the attached Professional Services Agreement ( PSA) with Pacific Advanced Civil Engineering, Inc. (PACE) in the amount of $ 975, 888to provide professional engineering consulting services for the design of the CIP PW 20- 16 Groundwater Treatment Improvements, which will include addition of PFAS treatment at the LAWTF.
BACKGROUND:
PFAS are a group of man-ade chemicals used for fire -fighting foam, food packaging, stain and water- repellent and non- stick commercial products since the 1940s. PFAS are very persistent in the environment and in the human body - meaning they don' t break down and they can accumulate over time.
On October 11, 2019, Council approved the creation of CIP PW 20- 16 Groundwater Treatment Improvements after PFAS was discovered to be present in the City' s groundwater supply. This project is needed to address the presence of PFAS and other constituents of concern that have been detected in the City' s groundwater supply. State and Federal regulatory requirements associated with the use of groundwater containing PFAS for drinking water are anticipated to go into effect in 2029. Non- compliance with these regulations could result in enforcement actions, or discontinuation of using the City' s
wells for a drinking water supply.
On February 11, 2026, staff issued a Request for Proposals ( RFP) for professional engineering consulting services to provide design services to add PFAS treatment at the LAWTF. Two ( 2) proposals were received by the March 4, 2026 deadline. After 176

Improvements to existing facilities
The Orange County Water District ( OCWD) hired PACE to design wellhead treatment systems for six sites, encompassing seven Golden State Water Company wells located in the Cities of Stanton, Garden Grove, and Placentia.
The pressure vessel systems are designed to treat flows ranging from 400 to 3, 500 gallons per minute, tailored to each well' s
production capacity. Building on the findings of an OCWD pilot study, the treatment process includes pre - filtration using bag filters, followed by IX in steel pressure vessels to achieve the targeted water quality objectives.
PACE designed each system in alignment with the pilot study' recommendations while also developing alternative concept layouts to provide flexibility and options for stakeholder review.
PACE also coordinated with the IX media manufacturer to confirm the ability of the selected resin to treat perchlorate, an additional contaminant affecting one of the wells. With this confirmation, the affected well can now be added to production through one of the treatment systems if and when needed, improving overall supply flexibility. In addition to treatment system design, PACE prepared feasibility studies for two private pump - to -waste drain lines with proposed connections to the public storm drain system, ensuring effective and compliant management of waste streams during operations. Through this work, PACE supports OCWD and Golden State Water Company by advancing cost- effective, site - specific solutions that ensure regulatory compliance and improve long- term water supply reliability across the region.

Due to rapid growth within their service area, Liberty Utilities has an immediated need to design and permit a new production well on an accelerated timeline. PACE was hired to perform an assessment and subsequent design of a 700 gpm production well and arsenic treatment system with provisions to add PFAS treatment. The system includes pretreatment, sodium hypochlorite disinfection, and stormwater management on a very compact site located within a residential neighborhood. In order to meet the project requirements, the design - build team proposed an approach utilizing multiple parallel paths of effort. Site grading and procurements will be started at risk while the design is being completed. The treated water will discharge directly into the existing distribution system, and backwash of the filters will be discharged to a cast - in -place concrete storage tank located below the treatment vessels and metered out to the sewer system.

City of Vernon Source Water Quality Assessment and PFAS Treatment Design Vernon, CA Relevant Features
Water quality assessment of seven active
water wells
Manganese, iron, and PFAS treatment
system design
Master Plan concept approach to
prioritize the most effective treatment
options and streamline future treatment
design
The City of Vernon engaged PACE to evaluate water quality concerns at its seven active groundwater wells and design wellhead treatment systems to address elevated levels of iron, manganese, and per- and polyfluoroalkyl substances ( PFAS). PACE developed a Master Plan to identify the most effective and feasible treatment strategies, establish a standardized approach for future facilities, and provide the City with a dear roadmap to ensure regulatory compliance and long- term water reliability. The treatment design considers the unique challenge of managing multiple contaminants with different treatment requirements. Iron and manganese removal requires oxidation with free chlorine prior to filtration through Greensand media, while PFAS removal relies on ion exchange resins that are sensitive to free chlorine exposure. To address this, PACE' s design incorporates dechlorination steps with provisions for emergency off -spec discharges to protect the PFAS treatment media. In parallel, the team is evaluating the application of novel PFAS treatment media that are resistant to free chlorine but require California Division of Drinking Water ( DDW) approval before implementation.
PACE is also conducting pilot testing to confirm the performance of different media for the removal of site -specific contaminants. The pilot program evaluates the free chlorine demand required for effective iron and manganese oxidation, the level of dechlorination needed following the Greensand filters, and the impacts of free chlorine on both the ion exchange and novel medias being piloted. These efforts ensure that the full- scale treatment design is supported by site - specific data, providing confidence in treatment performance and long- term system reliability.

PACE provided multiple phases of project development, laboratory services, piloting, concept development, water treatment facility engineering, planning division graphics, and startup and operations support services on this innovative and unique treatment system for the City of Huntington Beach. Sophisticated desktop, bench - scale, pilot - scale, and full- scale demonstrations were provided for confirmation of the proposed biological treatment of reduced non - oxidized) drinking water quality constituents in the potable supply at Well 9 and other City wells. This first stage of work confirmed mechanisms for biological oxidation of hydrogen sulfide. This important and unique process was presented at several national conferences, including the American Water Works Association ( AWWA).
Design of the complete 3, 000 gpm ( 4. 3 MGD) treatment facility included six 10 - foot diameter biological activated carbon ( BAC) filtration vessels, with complete structural, mechanical, electrical, and controls integration for reliable and simple operation. A custom filtration control panel was tied into the City' scentralized Supervisory Control and Data Acquisition ( SCADA) system for fully automated controls. PACE provided all project bid documents, permitting, and coordination with Southern California Edison and assisted the City with the bid process and construction support services. Monthly backwashing was needed for this treatment system. A 200 -foot long 8 -inch PVC sewer pipeline was installed under Warner Avenue to facilitate monthly backwashing of the treatment system by diverting wastewater into the new sewer line during backwash operation. To minimize odor and costs, PACE designed the pipeline using a shallow sewer line connection with a drop bowl assembly to create a smoother flow to minimize splashing, resulting in decreased odor.

simultaneous removal of PFAS and H2S
6 Designed an invert siphon for backwash
discharge to the existing sewer system
The Lampson Water Well produces up to 4, 000 gpm and is one of the City of Seal Beach' sfour water wells. Historically high hydrogen sulfide ( H2S) concentration levels have caused the well to be underutilized, operating at low flow rates to avoid odor complaints. PACE was contracted by the City to evaluate treatment alternatives to efficiently reduce H2S concentration levels. On - site pilot testing was employed to evaluate the viability of a biological treatment process using granular activated carbon ( GAC) with and without plastic media and under various operating conditions. The pilot testing allowed for troubleshooting and refinement that led to selection of the biological activated carbon ( BAC) process. The final system design effectively removes H2S odors and reduces chlorine chemical dosage using four 12 -foot diameter steel pressure vessels, and also allows for future incorporation of PFAS treatment.
PACE also designed the electrical and controls system for the new equipment, including lighting. Additionally, since the filter vessels need periodic backwashing and the wastewater can be discharged to the existing sewer system, PACE designed an inverted sewer siphon to increase flow capacity through an existing choke point. Approximately 100 feet of 6 -inch pipeline was designed and located along an adjacent roadway. PACE also assisted the City in obtaining the DDW permit.

The Sweetwater Authority in southern San Diego County sought to remove color from the drinking water within the National City area, which was caused by iron and manganese in three major supply wells. PACE completed a 3 - month pilot project using five different treatment trains for oxidative filtration of iron and manganese. The train consisting of" Greensand Plus," or manganese dioxide - coated sand, achieved treatment consistently to less than 5 parts per billion. By removing iron particles about 0. 45 micrometers in size, accumulation in the drinking water system in National City will be substantially reduced. The system includes backwash recovery to save water loss from backwash. The full- scale design integrates the proposed final treatment system into the existing site with a new booster pump skid and on - site water quality analyzers. PACE also provided drinking water permitting and approval assistance.

The LAWTF, originally constructed approximately ten years ago for arsenic removal from five municipal supply wells ( Wells 6, 7, 8, 9, and 10), has a design capacity of 6, 250 gpm. Based on prior evaluations, including the 2020 PFAS Treatment Alternatives Evaluation, the 2022 Centralized Treatment Feasibility Study, and subsequent technical memoranda, a centralized PFAS treatment system at LAWTF has been identified as the preferred alternative.
At a design flow rate of 6, 250 gpm, if Ion Exchange ( IX) is selected as the preferred treatment method, there will need to be four trains of two vessels ( lead - lag operation) using 12 - foot diameter vessels each. Each train has a capacity of 2, 000 gpm based on a typical hydraulic loading rate of 6 to 18 gpm/ sf.
The following rendering shows a preliminary layout of an IX PFAS treatment system that includes booster pumps to account for the additional headloss of the system and cartridge filters to prevent suspended solids from building up on the expensive media.

APPROACH STRATEGIES
9 Experience - Driven Design Optimization
PACE' slongstanding relationship with the operators who build and manage our treatment facilities has continually strengthened our design approach. Through years of collaboration with professionals responsible for day- to- day operations, maintenance, and performance optimization, we have incorporated real - world operational insight directly into our engineering process. This experience has resulted in treatment systems that are more robust, maintainable, and operationally efficient. Lessons learned from past operability reviews and long- term facility performance have been institutionalized within our design standards, ensuring that each project benefits from practical, field- tested knowledge rather than theory alone. 9 Early Performance Specification and Procurement Strategy PACE has the ability to incorporate performance - based specifications early in design to enhance project cost control, schedule reliability, and design flexibility. During preliminary design milestones, PACE identifies key process and equipment design criteria, such as flow rates, contaminant concentrations, and performance requirements, to develop comprehensive performance specifications well in advance of final design.
This early definition of equipment needs enables the client to pursue competitive pricing that can be locked in and held for a defined duration, reducing exposure to market fluctuations. It also provides the opportunity to pre -purchase long -lead equipment, ensuring critical components are secured before they impact the construction schedule.
By strategically advancing performance specifications early in the project, PACE helps clients de - risk procurement, accelerate delivery, and optimize design integration — all while maintaining flexibility to align final design details with the selected equipment supplier' srequirements.
Hydraulic Considerations and Pumping Strategy
Based on our experience designing PFAS treatment facilities, the addition of cartridge filtration and ion exchange ( IX) media vessels will introduce a meaningful increase in system headloss— particularly as media approaches the end of its operational life and prefilters require replacement. Under peak fouling conditions, the total incremental head across the PFAS treatment process can approach approximately 80 feet between the cartridge filters and media vessels.
Given this anticipated head requirement, the project must evaluate whether the existing well pumps have sufficient available head to reliably operate under worst - case treatment conditions. If not, supplemental pumping capacity will be required to maintain consistent treatment performance.
Because five wells feed the LAWTF treatment process, a dedicated booster pump station serving the PFAS system is likely to provide the most reliable and operationally flexible solution. A booster configuration allows the City to:
Preserve the existing well pump configuration
Maintain consistent flow through the
treatment system as media fouls
Provide operational redundancy and future
expandability
Avoid piecemeal pump replacements across
multiple wells
Optimize energy efficiency and control strategy

VOISII
C644 // CITY OF LATHROP PROFESSIONAL ENGINEERING SERVICES FOR THE ADDITION OF TREATMENT FOR PFAS AT THE LAWTF Our approach will include detailed hydraulic modeling to confirm dynamic head requirements under clean - bed and fouled - bed conditions, evaluate pump curves against existing well performance, and identify the most cost- effective and operationally sound pumping strategy.
The following hydraulic profile illustrates pressure losses across a similar PFAS treatment facility designed by PACE utilizing IX media. As shown, headloss through cartridge filtration and lead/ lag IX vessels was carefully evaluated to ensure reliable performance under both clean and end - of -run conditions. This same level of rigor will be applied to the LAWTF PFAS treatment addition to ensure long- term hydraulic reliability and regulatory compliance.

Media Performance Validation Through Pilot and Bench -Scale Testing Piloting will be conducted to establish site - specific design criteria and validate media performance under actual groundwater conditions prior to full- scale implementation. The pilot study will reduce design uncertainty, refine hydraulic loading parameters, and support defensible lifecycle cost comparisons for this major infrastructure investment.
PACE proposes to evaluate both ion exchange ( IX) media and granular activated carbon ( GAC) for PFAS removal in order to evaluate both PACE' ssuggested treatment method ( IX) and GAC. Comparative testing will allow direct assessment of breakthrough behavior, media utilization efficiency, empty bed contact time EBCT) requirements, pressure loss development, and projected media replacement intervals.
The pilot system will include upstream cartridge filtration to protect IX media from particulate fouling and ensure representative full- scale performance. Testing will be conducted using PACE' s advanced pilot platform with interchangeable columns to enable parallel evaluation of media types under controlled hydraulic conditions.

MEHTODOLOGY & APPROACH 23
Ion exchange media generally exhibit higher PFAS capacity and shorter required EBCTs compared to GAC, resulting in smaller vessel sizing and reduced site footprint. While IX media costs per unit volume are typically higher, improved capacity and reduced infrastructure requirements can offset capital and O&M expenditures over the life of the facility. Conversely, GAC performance may be influenced by competitive adsorption from co- occurring organic matter and background ions, potentially impacting media run length.
The pilot will quantify these effects under actual water quality conditions.
Media replacement frequency is anticipated to be a primary lifecycle cost driver for either technology and will be rigorously evaluated through monitored breakthrough curves and loading rate analysis.
The pilot may be configured to simulate PFAS treatment either upstream of the existing arsenic treatment system, consistent with prior planning assumptions, or downstream of arsenic treatment. An upstream configuration avoids oxidant exposure to adsorption media, which would otherwise require dechlorination and introduce additional operational complexity.
However, locating treatment upstream may also increase the potential for competitive adsorption and media fouling. Inorganic constituents such as iron, manganese, and calcium can form precipitates that deposit on the adsorbent surface and reduce effective capacity. Competitive adsorption is particularly relevant in drinking water applications, where target PFAS compounds coexist with other adsorbable constituents. The extent of competition depends on the relative adsorption affinity of competing species, their concentrations, and the type of media utilized. Even though this is groundwater without high concentrations of typically competitive chemicals, it should be considered that any competitive adsorption will reduce media life.
Although the source groundwater contains arsenic, dissolved ( aqueous) arsenic is not strongly adsorbed by GAC or typical PFAS- selective IX media. In contrast, particulate or precipitated arsenic species may contribute to fouling if present.
Pilot results will be used to establish full- scale design parameters including EBCT, vessel sizing, hydraulic loading rates, anticipated run length, and preliminary lifecycle cost projections to support final technology selection.
Proactive Agency Coordination and Permitting Management PACE takes a structured, proactive approach to regulatory coordination that ensures efficient approvals and consistent compliance across multiple jurisdictions. PACE will coordinate directly with the Division of Drinking Water ( DDW) to present the project scope, permitting pathway, and preliminary design at the 60% milestone. PACE will submit formal plans and attend review meetings at the 60%, 90%, and 100% design stages to maintain alignment with DDW reviewers. A draft Operations, Maintenance, and Monitoring Plan ( OMMP) will also be prepared at 60% design to allow early regulatory input on operational and reporting expectations. This approach minimizes late -stage comments, avoids redesign, and expedites permit issuance.
PACE' sregulatory approach emphasizes early agency coordination, clear documentation, and proactive issue resolution. By engaging regulators after the 60% design milestone — when the project' stechnical foundation is solid yet adaptable — PACE ensures that each system design advances efficiently through review and approval, minimizing delays, reducing rework, and delivering fully compliant, ready -to - construct solutions for Liberty Utilities.

PACE will mobilize, install, and operate a pilot system to establish full- scale design criteria and evaluate operational requirements, including comparative media replacement frequency for GAC and IX. The pilot will assess GAC and IX performance under site -specific water quality conditions upstream of the existing arsenic treatment system.
For this work, PACE will mobilize its advanced pilot skid to the project site. The skid has an approximate 9 ft by 6 ft footprint and is designed for continuous 24/ 7, largely unattended operation, except for manual filter backwash. The system includes four parallel, interchangeable - diameter contactor columns; upstream cartridge filters; upstream pressure transmitters; continuous flow monitoring; backwash capability; and online temperature, turbidity, and pH monitoring with PLC - based automation, data acquisition, remote data access, and customizable alarm functionality.
Although not explicitly required, PACE will prepare an internal Pilot Study Test Plan, which will be shared with the City, to define operational parameters, monitoring protocols, and performance criteria in advance of testing to ensure defensible results. Test Plan will establish target EBCTs, service flow and surface loading rates, backwash trigger criteria, sampling locations and analytical parameters, and data evaluation and QA/C procedures. RSSCT results conducted by Calgon Carbon and reported by EKI for the City 2020) will be used to size pilot columns and set flow rates to achieve media breakthrough within the pilot duration while avoiding channeling through the media.
PACE will mobilize and deploy its advanced pilot skid from the PACE Environmental Water Laboratory to the project site. PACE will perform all startup testing flow testing to ensure that the instruments are functioning properly and connections do not leak.
It is assumed that required storm drain connection, raw water connection, potable water connection ( for pilot startup and flow testing), and 110V power will be provided by the City.
The primary analytical parameters for the study will be regulated PFAS compounds. Operation will continue until effluent concentrations of regulated PFAS compounds ( PFOA, PFOS, PFNA, PFHxS, GenX, and Hazard Index PFAS) achieve their respective MCLs, or for a maximum of six months, whichever occurs first. Pilot extension, if authorized by the City, will be performed for additional compensation.
PACE will perform site visits at two- week intervals to verify instrumentation performance and inspect for leaks. Between visits, the system will be monitored remotely; response to unexpected issues will include coordination with City staff or site mobilization by PACE, as warranted by issue severity.
PACE assumes that routine water sampling will be performed by City staff to minimize pilot costs. PACE will provide sampling protocols, laboratory -supplied bottles, and shipping materials, as required, along with alerts for when water samples shall be taken based on bed volumes treated. It is assumed that laboratory costs will be covered by the City.
Upon completion of testing, PACE will disconnect, remove, and transport the pilot skid back to the PACE Environmental Water Laboratory.
PACE will prepare a Technical Memorandum summarizing pilot operating conditions, analytical results, media performance comparisons, and projected full- scale design criteria. PACE will also meet with the City to present the findings and recommendations in order to proceed with the design phase of the project.
Deliverable: Pilot Study Technical Memorandum
PACE will prepare a Basis of Design ( BOD) report documenting the design criteria, assumptions, and selected treatment approach for the project. The BOD will incorporate findings from the pilot study, including observed treatment performance, operational considerations, and key design parameters derived from pilot results.

Task Series 3
Task 3.1— Bidding
Assistance
PACE will provide bidding phase support, including responding to bidder questions related to the technical aspects of the design and issuing addenda as necessary. PACE will provide a consolidated set of plans and specifications.
Task Series 4
Task 4.1— Engineering
Support Services During
Construction
PACE will provide construction phase support, including review of shop drawings and equipment submittals to confirm conformance with the design intent, and responses to contractor RFIs. PACE will also participate in bi- weekly coordination calls to discuss construction progress and interface with the on -site construction manager.
Task Series 5
Task 5.1— Permitting
Task 5. 2 — Regulatory
Compliance
It is anticipated that Mechanical, Structural, Grading/ Paving, and Encroachment permits may be required from the local Authority Having Jurisdiction ( AHJ).
PACE will coordinate with the City and applicable agencies and prepare and submit required permit applications and supporting documentation. It is assumed that the City will serve as the permit applicant where required and will pay all permit application and agency review fees.
It is assumed that the California Environmental Quality Act ( CEQA) permit will not be needed for this project.
Early engagement with the SWRCB Division of Drinking Water ( DDW) is crucial to ensuring major comments are not received after design is complete. For this reason, PACE intends to engage the DDW after the 60% design deliverable. Typically, this follows approximately 2 weeks after the City has completed the internal review so that any major issues may be incorporated. Plans will then be sent to the permitting agency, and a review meeting is set to discuss the project and any comments received.
PACE intends to provide a plan submittal after the 60%, 90% and 100% design submittal and will be available to attend one meeting with DDW to discuss the project. For the 60% design submittal a draft Operation Maintenance and Monitoring Plan OMMP) will be prepared and updated for subsequent submittals.
It is assumed that the City will be able to assist in setting up these meetings with the applicable regulatory agency since there are likely contacts in place for reporting purposes for each site.
Deliverable: Operation Maintenance and Monitoring Plan (OMMP) Task Series 6
Task 6.1— Final
Construction Report
Task 6. 2 — Record
Drawings
Using information collected during construction, start- up, and commissioning of the PFAS treatment addition, PACE will prepare a Final Construction Report documenting installation, operational verification, and initial performance of the treatment system based on information received from the Contractor and observations while on -site. The report will summarize construction activities, major equipment installed, and any field modifications from the permitted design documents. Documentation will include confirmation of media installation, integration with existing well and electrical systems, and verification that installation is consistent with the approved plans.
The report will also summarize start- up and commissioning activities, and initial performance testing results, including system flow rates, pressure drop, and initial effluent PFAS sampling data. A discussion of operator training, O&M manual delivery, and coordination with regulatory agencies will be included. Final as -built drawings, commissioning checklists, and laboratory results will be appended as supporting documentation.
Deliverable: Final Construction Report
PACE will prepare Record Drawings based on contractor - provided as - built documentation. It is assumed that the Contractor will clearly identify and document all deviations from the issued - for -construction drawings that occurred during construction.
Record Drawings will reflect the information provided in the Contractor' sas- builts and other available project documentation. The Record Drawings will be stamped by PACE with the mutual understanding that they are based on and limited to the accuracy and completeness of information furnished by the Contractor.

He has performed engineering design and support in several areas including water treatment, pump stations, water conveyance and distribution, and surveying services. Mr. Peterson is adept at providing comprehensive civil and mechanical designs that are inventive, cost- effective, and practical and is experienced in construction services on various water resource systems. With his combined knowledge of water resource disciplines, he has been effective in the design, construction oversight, and operational support of numerous projects, including multi -functioning systems incorporating mechanical and biological systems and processes. He offers expertise in a multitude of groundwater treatment processes, including granular activated carbon ( GAC) and biological activated carbon ( BAC) systems, ion exchange, reverse osmosis ( RO), and other types of filtration systems, and has led field pilot testing of several technologies to refine equipping, design, and operations procedures.
RELATED EXPERIENCE
Orange County Water District / Golden State Water Company PFAS WeII Treatment — Orange County, CA
Mr. Peterson is serving as the Engineer of Record for the well treatment design for six water well sites, consisting of up to eight wells, for the Golden State Water Company. Three sites are within the City of Stanton, two sites are within the City of Garden Grove, and one site is within the City of Placentia. The pressure vessel treatment system will treat flows between 400 and 3, 500 gallons per minute. OCWD previously completed a pilot study and determined that the treatment process will consist of pre- treatment using bag filters, followed by ion exchange ( IX) media in steel pressure vessels. Based on the design well capacity at each site, the treatment system will be sized and designed to meet the treatment objective consistent with OCWD' s pilot study recommendations, while providing alternative concept plans for stakeholders to review. PACE will also prepare feasibility studies for two separate private pump -to -waste drain lines to connect to the existing public storm drain system.
City of Vernon Source Water Quality Assessment and PFAS Treatment Design — Vernon, CA Mr. Peterson is serving as the Sr. Project Engineer to evaluate water quality concerns at the City' sseven active well locations and design a treatment system to reduce levels of manganese, iron, and per- and polyfluoroalkyl substances ( PFAS). As part of the assessment, PACE will also develop a Master Plan approach for treatment systems at all seven wells to ascertain the most effective and feasible treatment options and streamline future treatment designs for the remaining wells.
California -American Water Company Hexavalent Chromium Removal — Los Angeles County, CA
Mr. Peterson is serving as Project Manager to design a hexavalent chromium removal system for six wells owned and operated by the California - American Water Company. Located in the East Pasadena and San Marino service areas, these wells have all been found to contain hexavalent chromium levels above the recently established Maximum Contaminant Level ( MCL). New strong base anion ( SBA) exchange resin removal facilities are being designed at four sites to remove hexavalent chromium from the well water, and the existing well pumps will be upgraded to provide sufficient pumping capacity through the SBA exchange system.
City of Seal Beach Lampson WeII Treatment and Sewer Siphon — Seal Beach, CA The Lampson Water Well produces up to 4, 000 gpm and is one of the City of Seal Beach' sfour water wells.
Historically high hydrogen sulfide ( H2S) concentration levels have caused the well to be underutilized, operating at low flow rates to avoid odor complaints. Mr. Peterson served as the Sr. Project Engineer for the pilot studies to evaluate the viability of a biological treatment process using granular activated carbon C644 // CITY OF LATHROP PROFESSIONAL ENGINEERING SERVICES FOR THE ADDITION OF TREATMENT FOR PFAS AT THE LAWTF PACE 229

RELATED EXPERIENCE CONT. GAC) with and without plastic media and under various operating conditions. The pilot testing allowed for troubleshooting and refinement that led to selection of the biological activated carbon ( BAC) process. The final system design effectively removes H2S odors and reduces chlorine chemical dosage using four 12 - foot diameter steel pressure vessels, and also allows for future incorporation of PFAS treatment. Additionally, since the filter vessels need periodic backwashing and the wastewater can be discharged to the existing sewer system, PACE designed an inverted sewer siphon to increase flow capacity through an existing choke point. Approximately 100 feet of 6 - inch pipeline was designed and located along an adjacent roadway.
Sweetwater Authority Iron and Manganese WeII Treatment System — National City, CA The Sweetwater Authority in southern San Diego County sought to remove color from the drinking water within the National City area, which was caused by iron and manganese in three major supply wells. Mr.
Peterson served as the Sr. Project Engineer for the 3 - month pilot project using five different treatment trains for oxidative filtration of iron and manganese. The train consisting of" Greensand Plus," or manganese dioxide - coated sand, achieved treatment consistently to less than 5 parts per billion. By removing iron particles about
0. 45 micrometers in size, accumulation in the drinking water system in National City will be substantially reduced. The system includes backwash recovery to save water loss from backwash. The full- scale design integrates the proposed final treatment system into the existing site with a new booster pump skid and on - site water quality analyzers. PACE also provided drinking water permitting and approval assistance.
City of Riverside Garner B Well PFOA/FOS Treatment Pilot Testing — Riverside, CA Mr. Peterson served as the Sr. Project Engineer to perform a condition assessment of the out -of -service GAC treatment system to determine the feasibility of rehabilitating the system into a full- scale pilot system to treat PFOA/FOS. The pilot study evaluated potential treatment alternatives and enhancements, including co -precipitation filtration and biological treatment, that could lower capital costs and/ or annual operations and maintenance costs compared to typical treatment methods. Upon determining that the rehabilitation was feasible, PACE prepared improvement plans and specifications to reactivate the treatment system, designed modifications to accommodate either GAC or ion exchange media, and specified components to be replaced, including the flow meter and tank lining.
Water Treatment Facility for Iron and Manganese Removal — Lakeside, CA As the Sr. Project Engineer, Mr. Peterson designed a groundwater treatment facility that treats 99% of the client' s water supply to meet U. S. Environmental Protection Agency ( EPA) primary and secondary drinking water standards for iron, manganese, arsenic, and uranium. The 500 gpm iron and manganese filtration system uses a proprietary filtration media that completely removes iron and manganese from the potable water supply without the use of complicated chemical injection systems. Later improvements to the filtration plant addressed new EPA compliance requirements for uranium removal using a uranium - specific ion exchange system that treats production water to an average of 5 micrograms per liter ( pg/ L) with a maximum concentration of 20 pg/ L, well below the EPA' s maximum contaminant level ( MCL) of 30 pg/ L. With a small footprint system in mind, PACE' s design was able to reduce capital and operational costs significantly. PACE continues to provide testing and operating supervisory oversight services to ensure optimal operation of the treatment facility.
Groundwater Iron and Manganese Filtration System — South Orange County, CA Mr. Peterson served as the Project Manager for the design, construction, and commissioning ofa new 1, 000 gpm iron and manganese filtration system for a booster pump station. The system was designed to improve reliability and operational flexibility, allowing the client to supply irrigation water needs from any of their groundwater wells, including wells with elevated levels of these contaminants. The treatment system consists of automatic inlet pressure regulation, chlorine pre -oxidation injection, four parallel manganese dioxide filter banks, and a semi - automated treatment bypass that allows the blending of low iron content well water with treated water. This increases the capacity of the booster pump station to 1, 500 gpm and provides source water equivalent to the capacity. When commissioned, the system was performance - tested at its maximum design flow rate with influent total iron concentrations as high as 15 milligrams per liter ( mg/ L) and consistently produced effluent with less than 0. 2 mg/ L.

Grand View Water Campus RO PFAS Groundwater Treatment Facility — Buckeye, AZ As Principal, Mr. Komor led the development of the treatment process approach for the Grand View reverse osmosis treatment project to deliver an Advanced Drinking WaterTreatment Facility for the City of Buckeye, Arizona. This infrastructure development project will provide residents with reliable and safe water for years and enhance the City' s water infrastructure to face droughts in the region. The Grand View RO Plant will be constructed in multiple phases, where 3 million gallons per day of groundwater treatment facility under phase 1 will be a 12 MGD plant at the buildout. The treatment system includes pretreatment, RO- based desalination, water stabilization, disinfection, and brine disposal. The proposed treatment system removes high salinity, nitrates, hardness and polyfluoroalkyl substances ( PFAS) from the groundwater and provides safe drinking water to residents meeting drinking water standards.
City of Riverside Garner B WeII PFOA/FOS Treatment Pilot Testing — Riverside, CA As QA/C Principal, Mr. Komor assisted in conducting a condition assessment ofthe out - of -service granular activated carbon ( GAC) treatment system to determine the feasibility of rehabilitating the system into a full- scale pilot system to treat perfluorooctanoic acid ( PFOA) and perfluorooctane sulfonate PFOS). The pilot study evaluated potential treatment alternatives and enhancements, including co - precipitation filtration and biological treatment, that could lower capital costs and/ or annual operations and maintenance costs compared to typical treatment methods. Upon determining that the rehabilitation was feasible, PACE prepared improvement plans and specifications to reactivate the treatment system, designed modifications to accommodate either GAC or ion exchange media, and specified components to be replaced, including the flow meter and tank lining.
Walnut Canyon Reservoir and Lenain Water Treatment Plant Operations and Water Infrastructure — Anaheim, CA
Mr. Komor served as the Project Manager in charge of the study and recommended optimal operation of Walnut Canyon Reservoir, a 1. 0 -billion - gallon raw water reservoir with a storing capacity of 3, 000 acre- feet located in Anaheim' shills and canyon area, as well as the Lenain WaterTreatment Plant. PACE conducted a series of bench - scale tests to determine optimal treatment processes that would prevent occurrences of taste and odor compounds, sulfide, and manganese. The PACE team monitored the sulfide and manganese concentrations at six different locations in the plant, as well as the ozone and chlorine levels, and provided quick feedback to the plant operators to ensure finished water met the drinking water standards for sulfide, manganese, and bromate.
Mesa Water District Wells Treatment System Upgrades — Costa Mesa, CA As the Project Manager, Mr. Komor led the civil, process, conveyance, and water quality improvements ofWells 1, 3, 5, 7, 8, and 9 for Mesa Water District. An innovative, low- cost approach was developed to treat colored water with ozone, preceded by monochloramine addition to suppress bromate formation.
The existing chloramination system was modified to add ammonia first, prior to chlorine addition, which resulted in substantial savings in chemicals and improvement in disinfection control. Efforts included extensive evaluation of the existing systems, site inventories, alternatives identification and evaluation, water quality analysis at PACE' Sin- house laboratory, bench scale pilot testing, and design services to automate operations, improve safety, and upgrade electrical and mechanical systems.

Kalaeloa Seawater Desalination Facility — Kapolei, HI
Dr. Whitener is serving as the Design Engineer under the Kalaeloa Desalco team for a new multi - phase seawater desalination facility in the Kalaeloa area of Oahu, HI, near Barber' sPoint. As Engineer of Record and prime design consultant for the project, PACE is providing overall process design and coordination, design of two seawater supply wells, pre -filtration, seawater reverse osmosis ( SWRO), various chemical storage and injection facilities, calcite filtration, final water quality stabilization, disinfection, final water storage, final water delivery, an underground injection control ( UIC) well, facility electrical, instrumentation and controls, and Supervisory Control and Data Acquisition ( SCADA) responses. Once completed, the Kalaeloa Seawater Desalination Facility will have a production capacity of 1. 7 MGD with additional future phases expandable to a final capacity of 5. 1 MGD. As part of the design process, Dr. Whitener assisted with the development of a full- scale post -treatment process pilot system and pilot testing protocol to test the remineralization process for both quality and corrosion protection and to meet existing groundwater conditions.
Santa Monica Sustainable Water Infrastructure Project ( SWIP) Advanced Water Treatment Facility ( AWTF) — Santa Monica, CA
PACE was responsible for the design of the Advanced Water Treatment Facility ( AWTF), a key component of the City of Santa Monica' sSustainable Water Infrastructure Project ( SWIP). The AWTF treats a combination of raw wastewater and harvested stormwater, producing 1. 0 MGD of purified water for groundwater augmentation. The facility is one of the first to take in raw wastewater, fully oxidize the stream via biological treatment, and provide the required pathogen reduction to meet California Title 22 regulations for indirect potable reuse with reduction of 12 - log virus, 10 - log Cryptosporidium, and 10 -log Giardia all within one facility. Dr. Whitener assisted with troubleshooting the post -treatment remineralization system by visiting the site, creating a study plan, and organizing data to investigate the cause of the issue. This work ensured that quality water would continue to be produced by the facility and that all regulated corrosion control parameters remained stable. The treatment process consists of a five - barrier stream: MBR, cartridge filtration, reverse osmosis ( RO), ultraviolet advanced oxidation process ( UVAOP), and chlorine disinfection.

SR. INSTRUVENTATION & CONTROLS SPECIALIST - Ernesto Camarena RELATED EXPERIENCE CONT. Dateland Groundwater Treatment Plant Pretreatment GAC and RO Upgrade — Dateland, AZ
Mr. Camarena provided instrumentation and controls design for this brackish groundwater potable water treatment project. PACE provided Dateland Public Service Company with several inland - desalination alternatives, engineering design, environmental permitting, and grant funding application services to improve and expand their existing groundwater reverse osmosis ( RO) treatment system which features a granular activated carbon ( GAC) pre - filtration and ion exchange ( IX) skid. The groundwater in the Dateland basin contains several trace contaminants including arsenic and fluoride, has irrigation inhibitors boron, chloride, and sodium, and overall contains high levels of total dissolved solids ( TDS). PACE was able to increase the treatment capacity to over 80, 000 GPD and increased recovery from 65 to 85%.
City of Santa Monica Sustainable Water Infrastructure Project ( SWIP) Advanced Water Recycling Facility — Santa Monica, CA
Mr. Camarena served as the Sr. Instrumentation & Controls Specialist for the design of the Advanced Water Treatment Facility (AWTF), a key component of the City of Santa Monica' sSustainable Water Infrastructure Project ( SWIP). The AWTF treats a combination of raw wastewater and harvested stormwater, producing
1. 0 MGD of purified water for groundwater augmentation. The facility is one of the first to take in raw wastewater, fully oxidize the stream via biological treatment, and provide the pathogen reduction requirements to meet California Title 22 regulations for Indirect Potable Reuse ( IPR) of 12 - log virus, 10 -log cryptosporidium, and 10 - log giardia all within one facility. The treatment process consists of a five -barrier stream: membrane bioreactor ( MBR), cartridge filtration, RO, ultraviolet advanced oxidation process UVAOP), and chlorine disinfection. The facility is the first of its kind to receive pathogen reduction credits through the cartridge filtration process. This was accomplished through the careful selection of cartridge vessels that meet the California Surface Water Treatment Rule for reduction of cryptosporidium and giardia, thus providing added benefit for a process that is typically required for RO protection but does not provide any further benefits. The cartridge filtration process has real time monitoring of differential pressure across the filter vessels, flow rate monitoring, and discharge turbidity for each train to ensure there is no breakthrough or overloading of the filtration vessels which would eliminate the pathogen reduction credits.
The AWTF is located underneath the City' s
Civic Center parking lot with the first level below ground serving as the mechanical treatment area and the second level containing the process tanks.
Santa Ana Country Club Pretreatment GAC and RO Filtration System — Santa Ana, CA As the Controls and P&ID Specialist, Mr. Camarena designed the controls for this reverse osmosis treatment system to provide a custom water source for irrigating the golf course greens at the Santa Ana Country Club. PACE developed the treatment process, utilized performance -based specifications ( a highly effective process for reducing costs and guaranteeing performance of equipment), engineering design of civil, mechanical, electrical and control systems and treated water storage systems and cost estimating. PACE also designed phase II of the system including a GAC pre -filtration system, which assists with reducing organic fouling of the desalination system.
LACFD Fire Camp 11 and Henninger Flats Campground Wells and Potable Water Treatment System — Los Angeles County, CA
Mr. Camarena served as the Sr. Instrumentation and Controls Specialist for the design of the potable water treatment systems for five remote sites owned and operated by the Los Angeles County Fire Department.
The SCADA communications, designed by Mr. Camarena, enable remote monitoring and control for the wells and treatment systems with that automatically switch to propane generators in the event of a power loss. The modular treatment facility designed provides consistency of equipment and functionality and reduces overall maintenance costs for the Fire Department. Both Fire Camp 11 and the Henninger Flats Campground contain groundwater under the influence of surface water and are therefore required to have a surface water treatment system. PACE completed evaluations of all of the camp facilities and looked at several processes and determined that the use of a packaged Rosedale filter system followed by chlorination was the most cost effective ( in both capital and operational) way to meet State regulations.

ENGEO' s environmental subconsultant assisted with permit preparation and processing with Caltrans and the California Coastal Commission. Engineering support services were provided during construction and the City celebrated the completion of the project in 2023. ENGEO is currently completing the design of another section of coastal bluff that will be stabilized after a delay due to potential cultural resources in this area. ENGEO has also provided similar services in the past to the City of Pismo Beach for other portions of the community' scoastal bluff. In addition, we are currently preparing geologic and coastal engineering evaluations on other City- and privately -owned coastal properties that are at risk due to coastal erosion.

Project Manager. Randy acted as the Project Manager,
performing various analyses, and coordinating design
geotechnical recommendation with the project design team.
The County of San Luis Obispo ( County) experienced a series of stormrelated washouts of the existing 8 -foot diameter double culvert crossing beneath Chimney Rock Road in early 2023, which created an 80 -foot long, 50 -foot deep scour pit. The County created an emergency temporary bypass
April 2023) with riprap rock slope protection ( RSP) and a temporary onelane bridge over Franklin Creek ( June 2023) to replace the washedout culvert crossing. The purpose of the proposed project is to replace the temporary crossing with a permanent bridge.
The permanent bridge will consist of a new twolane bridge over Franklin Creek that will span 175 -feet. The bridge deck will consist of a concrete box girder that is founded on 48 - inch diameter castindrilledhole ( CIDH) piles. The design of the bridge and improvements will generally be in accordance with Caltrans methodology. Challenges of the project include presence of existing fill, variable bedrock depth, potentially liquefiable soil and significant kinematic loads onto the piles due to lateral spread.

CITY MANAGER' S REPORT
APRIL 13, 2026 CITY COUNCIL REGULAR MEETING
ITEM:
RECOMMENDATION:
APPROVE CONTRACT WITH CALIFORNIA
CONSULTING, INC., FOR COMPREHENSIVE
GRANT WRITING SERVICES FOR THE PARKS
AND RECREATION DEPARTMENT
Adopt Resolution to Approve a Contract with
California Consulting, Inc., for Comprehensive
Grant Writing Services for the Parks and
Recreation Department
SUMMARY:
The Parks and Recreation Department requests City Council approval to enter into a professional services agreement with California Consulting, Inc., for grant writing and administration services in support of Parks and Recreation Department projects, including the Lathrop Multi - Purpose Community Center Complex. The proposed agreement would have a 14 -month term beginning May 1, 2026, in an amount not to exceed $ 56, 000 and would be funded through Capital Improvement Project ( CIP) PK 22- 05.
BACKGROUND:
In November 2025, the City Council approved the conceptual design for the Lathrop Multi - Purpose Community Center Complex ( Option A - Linear Design). Since that time, staff has continued advancing implementation efforts for this significant community project. The total estimated cost of the overall complex is approximately 161 million, with the community center phase alone estimated at $ 90 million.
Given the scale of the project, development will occur in phases and will rely heavily on securing external funding sources. Currently, the City has approximately $ 25 million in Cultural and Leisure Funds available, with an additional $ 10 million anticipated over the next five years. While these funds provide a strong foundation, they are insufficient to fully deliver the project without supplemental grant funding and strategic fundraising efforts.
Several competitive grant opportunities have recently become available that align with the project scope, including:
Statewide Park Development and Community Revitalization Program ( SPP) - up to $ 8. 5 million
Extreme Heat and Community Resilience Program ( EHCRP) - up to $ 4 million Community Resilience Centers ( CRC) Program - up to $ 10 million Land and Water Conservation Fund ( LWCF) - up to $ 6 million 258
CITY MANAGER' S REPORT
APRIL 13, 2026 CITY COUNCIL REGULAR MEETING
APPROVE CONTRACT WITH CALIFORNIA CONSULTING, INC., FOR
COMPREHENSIVE GRANT WRITING SERVICES FOR THE PARKS AND
RECREATION DEPARTMENT
Over the past month, the Parks and Recreation Department evaluated qualified grant writing firms with demonstrated experience in securing state, federal, and private funding for large- scale municipal projects. Based on qualifications, experience, approach, and cost- effectiveness, staff identified California Consulting, Inc., as the firm that demonstrated the strongest overall fit for the project.
Founded in 2004, California Consulting, Inc., is the largest grant writing firm in California, serving approximately 80 public agencies statewide. The firm has secured over $ 1. 6 billion in grant funding and offers a full -service approach that includes funding analysis, grant research, application development, and post -award administration. Their structured methodology includes needs assessments, strategic grant planning, community engagement support, and ongoing coordination with grantors.
Grant applications for programs of this scale are highly technical and competitive, often requiring detailed narratives, multiple submissions, stakeholder engagement, and strict adherence to deadlines. Professional grant writing services will significantly improve the City' scompetitiveness and reduce staff workload. Notably, California Consulting, Inc. has demonstrated strong results with comparable agencies, including the City of Patterson, which achieved a 1, 701% return on investment over nine years.
The proposed scope of services includes:
Funding needs analysis and priority identification
Grant research and evaluation
Grant proposal development and submission
Grant administration and compliance support
The contract will be administered by the Parks and Recreation Department, with coordination across all departments as needed.
RECOMMENDATION:
Staff recommend that the City Council approve a professional services agreement with California Consulting, Inc., for grant writing and administration services.
Approval of this agreement will position the City to aggressively pursue critical external funding opportunities, maximize competitiveness for highly technical grant programs, and accelerate implementation of the Lathrop Multi -Purpose Community Center Complex.
The cost of the contract is expected to be fully offset by grant funds secured through these efforts, making this a strategic investment toward delivering this community project.

APPROVE CONTRACT WITH CALIFORNIA CONSULTING, INC., FOR
COMPREHENSIVE GRANT WRITING SERVICES FOR THE PARKS AND
RECREATION DEPARTMENT
FISCAL IMPACT:
The proposed agreement with California Consulting, Inc. includes a not -to -exceed amount of $ 56, 000 over a 14 -month term. Sufficient funding is available within the approved Capital Improvement Project ( CIP) PK 22- 05, Lathrop Multi - Purpose Community Center Complex.
No additional General Fund resources are required. The cost of the contract is anticipated to be fully offset by grant funding secured through these services.
However, if all targeted grant applications are unsuccessful and no grant awards are received, the cost of the grant writing services will be reimbursed to CIP PK 22- 05 from another eligible City funding source via a future Council action. Given the scale of potential grant opportunities, this investment represents a cost- effective strategy to leverage external funding and reduce the City' s financial burden for the project.
