That the Corona Utility Authority review, ratify, and, to the extent necessary, direct the City Council to take the above actions.

BACKGROUND & HISTORY:

On January 5, 2022, City Council adopted Resolution No. 2022-002, establishing the Capital Improvement Project, Rudell Road Sewer Extension, for the construction of approximately 1,600 lineal feet of new sewer main within Ontario Avenue between El Cerrito Road and Rudell Road and within the full length of Rudell Road. The project will benefit a total of eighteen (18) parcels, which include fifteen (15) parcels located along Rudell Road, by providing the opportunity for future sewer connections.

Rescare Holdings, represented by Mr. Amed Franco and Mr. James Tran, owns an existing parcel located at 7550 Rudell Road, in the unincorporated County of Riverside area of El Cerrito, which is in the City of Corona’s service area. The New Horizons Elderly Residential Care Facility operates at this address, which is currently being served by an existing septic system. They are seeking to expand their facilities and have expressed an interest in connecting to the City sewer system. The State of California Regional Water Quality Control Board - Region 8 (RWQCB8) has determined that the parcel at 7550 Rudell Road will not be permitted to install an additional septic system for the proposed facilities expansion. In 2021, Rescare Holdings subsequently contacted the City to request an extension of a sewer line from the nearest terminal manhole located at the intersection of El Cerrito Road and Ontario Avenue to their property on Rudell Road.

To coincide with the State and County’s legislation and regulations to protect water quality and public health, the City of Corona Utilities Department aims to eventually connect all existing homes on Rudell Road that are currently using septic systems to the City sewer system.

Corona Municipal Code Section 13.12.100 requires that prior to connecting to the City’s sewer collection system, the person requesting such connection shall pay a construction

charge to cover the proportionate cost of constructing the public sewer in the amount, manner, and time of payment established by resolution of the City Council. Upon completion of the Rudell Road Sewer Extension Project, the City will document and determine the actual Total Cost of constructing the project and any laterals constructed during the project and then calculate the actual construction charges owed by each benefitted parcel based upon the fair share percentages established in Resolution No. 2022-002.

ANALYSIS:

This Project was advertised for bids on February 6, 2025, pursuant to Corona Municipal Code Section 3.08.090, the State's Public Projects – Formal Bidding Procedure, and Public Contract Code requirements. Fifteen (15) contractors were notified of the City’s pre-qualification list. On June 24, 2025, five (5) bids were received from pre-qualified contractors through the PlanetBids bidding service.

The following is a summary of the bid results and the Engineer’s Estimate:

ENVIRONMENTAL ANALYSIS:

This action is categorically exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the commonsense rule that CEQA applies only to projects that have the potential for causing significant effects on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. This action is also exempt pursuant to Section 15282(k), which provides that the installation of new pipeline or maintenance, repair, restoration, removal, or demolition of an existing pipeline, as set forth in Section 21080.21 of the Public Resources Code, is exempt as long as the project does not exceed one mile in length.

WHEREAS, the City Council desires that the amount of the construction charge for the Rudell Road Sewer Extension be imposed and collected based upon the actual Total Cost (defined below) for the Rudell Road Sewer Extension; and WHEREAS, the City Council desires to authorize the City Manager or his or her designee to enter into payment plans with eligible customers pursuant to Corona Municipal Code sections 13.12.100 and 13.14.060 and to update the amount of the construction charges established herein based upon the Total Costs to construct the Rudell Road Sewer Extension; and WHEREAS, the construction charges imposed and collected for the Rudell Road Sewer Extension Project pursuant to this Resolution shall be used to reimburse the City of the costs and expenses incurred to construct the Rudell Road Sewer Extension Project.

NOW, THEREFORE, BE IT RESOLVED BY THE CITY COUNCIL OF
CITY OF CORONA, CALIFORNIA AS FOLLOWS:

SECTION 1. Findings. The recitals set forth above are hereby adopted as findings in support of this Resolution.

CA\JR\06200.12750\10256958.1
- 3 -
SECTION 2. Construction Charge. Pursuant to Corona Municipal Code section

13.12.100, the City Council hereby establishes and adopts an amount equal to the Total Cost to construct the Rudell Road Sewer Extension Project as the construction charge to be collected from the Benefitted Parcels prior to connection to the City’s sewer system (“Construction Charge”). For purposes of this Resolution and calculating the Construction Charge, the “Total Cost” of constructing the Rudell Road Sewer Extension Project shall include, without limitation, all labor materials, tools, equipment, services, and incidental and customary work necessary to plan, engineer, design, environmentally review, permit, site, bid, and construct the Rudell Road Sewer Extension Project, including without limitation, all costs and expenses for the following:
engineering, architectural, appraisal, legal, and other consultant services throughout the preconstruction and construction phases; bid preparation and administration services (if necessary), soil, project and other surveying, inspection and testing services; construction and project management services; and all construction and project close out activities.

SECTION 3. Fair Share Allocation of Construction Charge. Pursuant to Corona Municipal Code section 13.12.100, the City Council hereby allocates the Construction Charge to each Benefitted Parcel based upon the percentage of linear footage of the portion of the Rudell Road Sewer Extension Project that is located along the property frontage of each Benefitted Parcel, as compared to the total linear footage of the frontages included in the Rudell Road Sewer Extension Project. The 3 parcels noted in red are two roadway intersections and one parcel which Riverside County is planning to acquire to shift the alignment of Envoy Avenue so that it lines up with Rudell Road as part of their upcoming project to widen Ontario Avenue/Temescal Canyon Road between Cajalco Road and Envoy Avenue. Therefore, these 3 areas are excluded from the fair share cost allocation and their frontage percentages are redistributed to the remaining parcels.

Such fair share allocation shall be as follows:

CA\JR\06200.12750\10256958.1
- 4 -
SECTION 4. Estimated Fair Share Construction Charge. Upon completion of the Rudell Road Sewer Extension Project, the City shall: (1) document and determine the actual total Cost of constructing the Rudell Road Sewer Extension; (2) calculate the actual Construction Charge owed by the Benefitted Parcels based upon the fair share percentages provided in Section 3 above; and (3) provide by certified mail such information to the owner(s) of each Benefitted Parcel, as such owner(s) appear on the last secured assessment roll as of the date of mailing. Each Benefitted Parcel shall be obligated to pay its fair share allocation of the actual Construction Charge prior to its connection to the City’s sewer system or enter into a payment plan agreement, as provided in Section 7. For informational purposes only, the City has estimated the Total Cost of constructing the Rudell Road Sewer Extension Project to be $1,000,000, and thus as of the date of this Resolution estimates the fair share of the Construction Charge for each Benefitted Parcel as follows:

SECTION 5. Site Plan for Rudell Road Sewer Extension Project. The site plan showing the proposed Rudell Road Sewer Extension and the Benefitted Parcels is attached hereto as Exhibit A and incorporated herein by reference.

SECTION 6. Construction Cost of Lateral Sewer Line. To the extent that the City

CA\JR\06200.12750\10256958.1
- 5 -
constructs a lateral sewer line to connect the sewer main line to a Benefitted Parcel, the owner of that Benefitted Parcel shall also pay to the City one hundred percent (100%) of the Total Cost (defined above) to construct the lateral sewer line.

SECTION 7. Payment Plan Agreement. As authorized by Corona Municipal Code sections 13.12.100 and 13.14.060, the owner of a Benefitted Parcel, if they are an “eligible customer”, may enter into a payment plan agreement with the City, in substantially the same form attached hereto as Exhibit B and incorporated herein by reference, for the payment of their fair share of the Construction Charge for the Rudell Road Sewer Extension Project and the Total Cost, if any, for the construction of the lateral sewer connection to the Benefitted Parcel, plus interest at the rate of 6 percent (6%) simple interest commencing upon connection of the Benefitted Parcel to the City’s sewer system.

SECTION 8. CEQA Findings. The City Council finds that the adoption of this Resolution is exempt pursuant to Section 15061(b)(3) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt from CEQA if the activity is covered by the general rule that CEQA applies only to projects that have the potential for causing a significant effect on the environment. Where it can be seen with certainty that there is no possibility that the activity in question may have a significant effect on the environment, the activity is not subject to CEQA. Adoption of this Resolution is also exempt pursuant to Section 15303(d), which provides that the construction of water main, sewage, electrical, gas, and other utility extensions of reasonable length to serve an adjacent single-family residence are exempt from CEQA. This Resolution simply establishes construction charges to cover the proportionate share of constructing the sewer lines and appurtenances necessary to connect a limited number of single-family residences, commercial businesses, and non-profit organizations located on Rudell Road and on Ontario Avenue to the City’s public sewer system. Construction of the sewer extension will be reviewed as a separate project. Therefore, no further environmental analysis is required for establishment of the construction charges for the Rudell Road Sewer Extension Project.

SECTION 9. Effective Date. This Resolution shall become effective on January 5, 2022.

PASSED, APPROVED AND ADOPTED this 5
th day of January, 2022.

(TYPE OF USER USER – ADDRESS)

1. PARTIES AND DATE.

This Payment Plan Agreement (“Agreement”) is made and entered into this DAY day of MONTH, YEAR (“Effective Date”) by and between the City of Corona, a California municipal corporation (“City”), and Rescare Holdings (“Owner”). City and Owner are at times referred to collectively as “Parties” and individually as “Party” herein.

2. RECITALS.

2.1 Subject Property. The Owner is the record owner of certain real property located at ADDRESS, Corona, California 92881, more particularly described in Exhibit A attached hereto and incorporated herein by reference (“Subject Property”). The Subject Property is currently served by an individual sewer septic system and the Owner desires to connect the Subject Property to the City’s sewer collection system.

2.2 Connection Fee/Charge. Corona Municipal Code section 13.12.100 requires that prior to connecting to the City’s sewer system, the person requesting such connection shall pay a construction charge to cover the proportionate cost of constructing the public sewer in the amount, manner, and time of payment established by resolution of the City Council.

2.3 Rudell Road Sewer Extension Project; Construction Charge. The parcel owner at ADDRESS is currently on septic system and would like to discontinue using his system and connect to the public sewerage system. The City’s sewer collection system is located more than 200 feet from such parcel. In order to connect such parcel to the City’s sewer collection system, it is necessary to construct an approximately 1,600-foot extension of the City sewer system, consisting of a sewer main line and appurtenances, from the existing terminal manhole at the intersection of El Cerrito Road and Ontario Avenue and extending northward on Ontario Avenue and then westward on Rudell Road (“Rudell Road Sewer Extension”). Pursuant to Resolution No. 2022-002, the City Council established a Construction Charge (defined below) for the construction

2 of the Rudell Road Sewer Extension Project equal to the actual Total Cost (as defined in Resolution No. 2022-002) of construction.

2.4 Allocation for Benefitted Parcels. Including the parcel noted above, the Rudell Road Sewer Extension will permit the following eighteen (18) single-family residential properties, commercial properties, and a church assembly building, which are currently connected to individual sewer septic systems, to be connected to the City’s sewer system: 19530 Ontario Avenue, 19520 Ontario Avenue, 19501 Ontario Avenue, 7640 Rudell Road, 7636 Rudell Road, 7634 Rudell Road, 7630 Rudell Road, 7626 Rudell Road, 7616 Rudell Road, 7600 Rudell Road, 7588 Rudell Road, 7574 Rudell Road, 7562 Rudell Road, 7550 Rudell Road, 7530 Rudell Road, 7520 Rudell Road, 7510 Rudell Road, and 7471 Rudell Road (“Benefitted Parcels”). Pursuant to Resolution No. 2022-002, the City Council has allocated the construction charge on a proportional basis to the Benefitted Parcels based upon the percentage of linear footage of the portion of the Rudell Road Sewer Extension that is located along the property frontage of each Benefitted Parcel compared to the total linear footage of the Rudell Road Sewer Extension.

2.5 Optional Sewer Lateral. In addition to the Rudell Road Sewer Extension, it is necessary to construct a lateral sewer line to connect the sewer main line to the Subject Property.

If the Owner wishes to have the City construct such sewer lateral, this Agreement shall also obligate Owner to pay the actual Total Cost incurred by the City to construct said lateral sewer line, as provided further herein.

2.6 Payment Agreement. Pursuant to Section 13.12.100 and Resolution No. 2022-002, the construction charge for the Rudell Road Sewer Extension Project and, if applicable, the Total Cost of the lateral sewer line connecting the sewer main line to the Subject Property, may be paid pursuant to this payment plan agreement entered into by the Owner and the City.

3.2 Construction Charge. Pursuant to Resolution No. 2022-002, the City has established a construction charge equal to the Total Cost (as defined in Resolution No. 2022-002) to construct the Rudell Road Sewer Extension Project to be collected from the Benefitted Parcels, including the Subject Property, prior to connection to the City’s sewer system (“Construction Charge”). The Construction Charge is allocated to the Benefitted Parcels based upon the percentage of linear footage of the portion of the Rudell Road Sewer Extension Project that is located along the property frontage of each Benefitted Parcel, as compared to the total linear footage of the Rudell Road Sewer Extension Project.

3.2.1 Allocation of Construction Charge for Subject Property. Pursuant to Resolution No. 2022-002, the fair share percentage allocated to the Subject Property is PERCENTAGE IN WORDS (PERCENTAGE IN NUMBERS%).

3 3.2.2 Estimated Construction Charge; Financed Construction Charge. For informational purposes only, the City has estimated the Total Cost of constructing the Rudell Road Sewer Extension to be one million dollars and no cents ($1,000,000), and thus as of the Effective Date estimates that the fair share of the Construction Charge for the Subject Property is TOTAL COST IN WORDS ($TOTAL COST IN NUMBERS) (“Estimated Construction Charge”). Upon completion of the Rudell Road Sewer Extension and the Lateral Line, the City shall: (1) document and determine the actual Total Cost of constructing the Rudell Road Sewer Extension; (2) calculate the actual Construction Charge owed by the Owner for the Subject Property based upon the fair share percentages provided in Section 2.2.1 above (“Financed Construction Charge”); and (3) provide by certified mail such information to the Owner.

3.3. Requested Lateral Sewer Line - Cost. At the request of Owner, City shall construct a lateral sewer line to connect the Subject Property to the sewer main line that will be constructed as part of the Rudell Road Sewer Extension Project (“Lateral Line”). Owner agrees to pay one hundred percent (100%) of the actual Total Cost (as defined in Resolution No. 2022-002) to construct the Lateral Line (“Actual Lateral Line Cost”). For informational purposes only, the current estimated Lateral Line Cost, based upon the City’s most recent engineering estimates and other reasonably available data, is Twelve Thousand Dollars ($12,000) (“Estimated Lateral Line Cost”).

3.4. Total Principal Obligation. The terms “Financed Construction Charge” and, if applicable, “Actual Lateral Line Cost” shall hereafter be collectively referred to as the “Total Principal Obligation” throughout this Agreement.

3.5 Monthly Payment Schedule.

Each Monthly Payment shall be due and payable in immediately available funds on or before fifth (5th) day of each month commencing with the first full month following completion of the Rudell Road Sewer Extension Project and the Lateral Line.

3.5.1 Estimated Total Principal Obligation; Updated Amortization Schedule. The Parties acknowledge that the Amortization Schedule is based upon the Estimated Construction Charge and the Estimated Lateral Line Cost. Once the Financed Construction Charge and the Actual Lateral Line Cost are determined pursuant to Sections 3.2.2 and 3.3 of this Agreement, the Parties agree that the Amortization Schedule will be updated accordingly to reflect the Total Principal Obligation, Owner shall sign such updated Amortization Schedule, and said updated Amortization Schedule shall be automatically incorporated into this Agreement by reference without an amendment to this Agreement.

3.6 Non-Transferable. Owner understands and agrees that the connection rights supplied by the City are not transferable and shall remain with the Subject Property, and that

4 neither Owner nor any other person or party shall be entitled to a refund of any amounts paid under this Agreement, for any reason.

3.7 Discontinuation of Sewer/Water Service.

Owner expressly waives any and all rights it may have under any uniform codes (including, but not limited to, the California Building Code), or under any other applicable law(s), to receive sewer and/or water service, except in compliance with this Agreement and to the extent authorized by applicable law.

3.8 Contractual Lien. Owner further agrees for itself, its heirs, successors, and assigns, that effective upon the execution of this Agreement, City shall have a lien upon the Subject Property to guarantee the full and timely performance by Owner of its obligations under this Agreement. The lien upon the Subject Property shall be in an amount equal to the unpaid portion of the Total Principal Obligation, plus any accrued interest and any costs incurred by the City to enforce this Agreement. Such lien may be enforced in the manner provided by law. This lien is in addition to any rights or remedies which the City may have which may arise by operation of any applicable law, including, without implied limitation, the Corona Municipal Code. The lien created pursuant to this Agreement shall occupy a priority position against the Subject Property senior to all other non-statutory monetary liens and encumbrances against the Subject Property, except to the extent that Owner lacks the right to grant the lien priority over other liens and encumbrances against the Subject Property existing as of the date of this Agreement.

3.9 Recordation and Enforcement. City may record this Agreement in the official records of the County of Riverside, and may take such action in law, equity, or otherwise, as City deems necessary to enforce the provisions of this Agreement, including but not limited to actions for injunctive relief.

REQUEST FOR CITY COUNCIL AND

CORONA UTILITY AUTHORITY ACTION
SUBJECT:

PROFESSIONAL SERVICES AGREEMENT WITH UTILITY SYSTEM SCIENCE &

SOFTWARE FOR THE SANITARY SEWER INFLOW AND INFILTRATION STUDY EXECUTIVE SUMMARY:

This staff report asks City Council to approve a Professional Services Agreement with Utility System Science & Software for the Sanitary Sewer Inflow and Infiltration Study, which will provide the City of Corona Utilities Department monitoring, inspection, and analysis services to support the City’s efforts to identify and address sources of extraneous water entering the sanitary sewer system, so that the City may design and implement an ongoing plan to control infiltration and inflow to the sewer system per City, State, and Federal guidelines.

RECOMMENDED ACTION:

That the City Council:
a. Award Request for Proposal 25-044AG to Utility Systems Science & Software to conduct a Sanitary Sewer Inflow and Infiltration Study.

b. Approve the Professional Services Agreement with Utility System Science & Software of Santa Ana, CA in the amount of $500,000 to conduct a Sanitary Sewer Inflow and Infiltration Study for an initial contract term through June 30, 2027. c. Authorize the City Manager, or his designee, to execute the Professional Services Agreement with Utility System Science & Software in the amount of $500,000 including any non-substantive extensions, purchase orders, change orders, and amendments up to the amount authorized in Corona Municipal Code Section

3.08.070(I) which is equivalent to 10% or $50,000.

That the Corona Utility Authority review, ratify, and to the extent necessary, direct that the City Council take the above actions.

BACKGROUND & HISTORY:

The City of Corona has 435 miles of gravity flow sanitary sewer lines, 22 miles of sanitary sewer force mains, 2,280 manholes, and 17 lift stations that convey wastewater through the City to the treatment facilities. The Utilities Department is responsible for maintenance and repairs of these facilities. Historically, the system has experienced higher volumes of flow during rain events. The City receives most of its annual rainfall between January and the end of March. The average depth of groundwater, as observed in both flat and hillside monitoring wells, typically ranges from 97 to 150 feet in elevation; however, this depth can decrease during the rainy season. Inflow is defined as stormwater entering the sewer system through improper connections, such as roof drains, whereas infiltration refers to groundwater permeating the system via defects like cracks, leaks, or deteriorated joints in sewer pipes. These issues can lead to capacity overloads, increased treatment costs, and environmental hazards, including sanitary sewer overflows (SSOs).

To ensure proper maintenance of these systems and prevent sewer spills, the Utilities Department aims to conduct a comprehensive Sanitary Sewer Infiltration and Inflow Study. This study represents a proactive approach to addressing challenges within the city's sewer system during rain events, intending to generate actionable data that will inform both immediate maintenance activities and long-term capital improvement planning, thereby enhancing system reliability and regulatory compliance. By leveraging historical data, advanced technologies, and strategic partnerships, the study seeks to improve system reliability and reduce environmental risks.

ANALYSIS:

On March 19, 2025, the Purchasing Division issued Request for Proposal (RFP) 25- 044AG following the City Municipal Code (CMC) Section 3.08.110 Non-Public Projects formal bidding procedure and purchasing policy on the City’s PlanetBids bidding portal.

A total of 265 firms were solicited through PlanetBids. Thirty-five (35) firms and bid service companies downloaded the RFP documents. In turn, the bid service companies notify their clients of the potential bid opportunity, thereby providing additional exposure for the project. Two (2) proposals were received through the PlanetBids bidding service by the proposal due date of May 6, 2025, from the following vendors:

The scope of work and estimated costs per task related to the Inflow and Infiltration study submitted by Utility System Science & Software are outlined as follows:

* These items are priced as “per each” and the exact number of events is unknown and will be determined based on the initial findings and the measurable rain events that occur during the study period.

Following the analysis of the proposal evaluation and interview with each bidder, Utility System Science & Software was selected as the recommended consultant for the project.

Utility System Science & Software’s proposal demonstrated superior technical expertise, extensive experience in conducting inflow and infiltration studies, and a cost-effective approach that aligns with the City’s budgetary constraints. Additionally, their proposed methodology included innovative techniques for identifying and mitigating inflow and infiltration issues, which are critical to achieving the project’s objectives. By addressing inflow and infiltration, the study contributes to the strategic goals of reducing sanitary sewer overflows, improving system efficiency, and minimizing repair costs.

Staff recommend that the City Council approve a Professional Services Agreement with Utility System Science & Software to conduct a Sanitary Sewer Inflow and Infiltration Study for $500,000. While the total base price is $154,680, many of the quoted items will Vendor City Evaluation

need to be used multiple times and the exact quantity is unknown and will be determined based on the initial findings and consultations with staff. Additionally, some quoted items are per rain event and the quantity of measurable rain events for the season cannot be predicted. Therefore, staff requests $500,000 so the consultant can complete the required work as rain events occur. The agreement includes installation of inflow and infiltration equipment, reporting data and rain season summary, cleaning and CCTV inspections, smoke testing, and storm event data collection and report to improve system reliability, reduce environmental risks, and support sustainable urban development.

FINANCIAL IMPACT:

Funding for the recommended action is available in the Sewer Inflow and Infiltration Study Operating and Maintenance Project No. 78460 within the Sewer Utility Fund 572.

ENVIRONMENTAL ANALYSIS:

This action is categorically exempt pursuant to Section 15302 (c) of the Guidelines for the California Environmental Quality Action (CEQA), which states that “operation, repair, maintenance, permitting, leasing, licensing, or minor alteration of existing public or private structures, facilities, mechanical equipment, or topographical features, involving negligible or no expansion of use beyond that existing at the time of the CEQA determination” and is therefore exempt from CEQA. This action involves the study of existing infrastructure to maintain public health and safety. Therefore, it is exempt from the requirements of CEQA, and no environmental analysis is required.

SCOPE OF SERVICES
Consultant promises and agrees to furnish to the City all labor, materials, tools, equipment, services, and incidental and customary work necessary to fully and adequately supply the professional sanitary sewer inflow and infiltration study services necessary for the Project. The Services are more particularly described herein.

The City of Corona, Utilities Department is seeking a qualified firm to perform Sanitary Sewer Infiltration and Inflow (I&I) Study for the upcoming rain season at various locations throughout the City, to be determined. The City has 435 miles of gravity flow sanitary sewer line, 22 miles of sanitary sewer force mains, 2,280 manholes, and 17 lift stations that the Utility Department is responsible for maintenance and repairs.

Sanitary Sewer Infiltration and Inflow (I&I) creates additional expense and maintenance issues throughout the Sanitary Sewer System.

The average depth of ground water varies from flat to hillside monitoring wells ranging from 97 feet to 150 feet in elevation, however, it can be shallower during the rainy season. The general area of the City of Corona receives the bulk of the annual rainfall between the months of January and the end of March.

The City’s goal is to develop and implement an ongoing plan to control infiltration and inflow to the sewer system per City, State and Federal Guidelines. Infiltration is water flow that enters the sanitary sewer system from the ground through defective pipes, pipe joints, connections and manholes. Other sanitary sewer system structures may also include, but not be limited to valves, pump stations, siphons, wet wells, diversion structures, other infrastructure that is upstream from the wastewater treatment systems. Inflow is water other than sanitary sewer flow that enters the sewer system from other sources such as manhole covers, possible connections to the storm drain system, storm waters, surface runoff, illicit connections or other discharges. Controlling I/I is an important method to avoid future potential Sanitary Sewer Overflow (SSO) events.

Provide all labor, equipment, materials, installation, labor and supervision to provide rainfall monitoring equipment and Sanitary Sewer Infiltration and Inflow equipment to report on a two (2) week basis during the rainy season (usually January to April of the year). Produce a seasonal summary report with remediation recommendations at the end of the season. During the “dry” season reports shall be on a storm-by-storm basis to report storm impacts to the system, report shall be submitted to the City’s Project Manager.

Provide locations of manholes near storm drain inlets where storm water may inflow into the sanitary sewer system during a storm event.

All equipment to be supplied must be rated to withstand wet, moist/humid, corrosive environments. Devices must be unmanned monitoring operations providing real time levels. All equipment shall be compatible with the proposed software used for data collection and reporting.

CORONA UTILITY AUTHORITY ACTION
SUBJECT:

AUTHORIZE CONTRACT CHANGE ORDER NO. 2 WITH R C FOSTER
CORPORATION IN THE AMOUNT OF $176,972 FOR THE LESTER POST DISINFECTION STATION PROJECT, PROJECT NO. UT-2013-02
EXECUTIVE SUMMARY:

This staff report requests that the City Council authorize Contract Change Order No. 2 for $176,972 to RC Foster Corporation for demobilization, rental, and equipment standby costs, and future remobilization due to the postponement of the scheduled winter shutdown of Lester Water Treatment Plant in January 2025.

RECOMMENDED ACTION:

That the City Council:
a. Authorize the City Manager, or his designee, to issue a Contract Change Order in the amount of $176,972 to RC Foster Corporation due to the postponement of the scheduled winter shutdown of Lester Water Treatment Plant in January 2025. b. Authorize the City Manager, or his designee, to execute a Contract Change Order with RC Foster Corporation to increase the contract amount by $176,972,

amending the total contract amount to $2,040,719 including any non-substantive extensions, change orders, purchase orders, and amendments up to $204,072, which is equivalent to 10% of the revised contract amount.

That the Corona Utility Authority review, ratify, and to the extent necessary, direct the City Council to take the above actions.

BACKGROUND & HISTORY:

The Lester Water Treatment Plant at 2970 Rimpau Avenue is a direct-filtration water treatment plant capable of treating up to 30 million gallons per day (MGD) of raw Metropolitan Water District (MWD) water. Untreated imported water flows through six dual-media filters. Filtered and treated MWD water leaves these filters and manifolds and goes into a 42” steel combined filter effluent pipe through different laterals, only one of which contains injection quills for disinfection.

This project will construct one post-disinfection chlorine injection vault downstream from all six filters so disinfection can occur for the entire plant at one location. This will greatly simplify the operation and reduce the risk of water leaving the plant without a proper chlorine residual. By completing this project, removing the filters for maintenance will no longer require a total plant shutdown, which would temporarily remove a critical 30-MGD component of the City’s water supply.

This project was originally advertised for construction bid in May 2022 to the Utilities Department’s Pre-Qualified Contractors list. At that time, the City received only one (1) bid from Pacific Hydrotech Corporation for $1,929,000. The engineer’s estimate provided at the time was $500,000. Due to inflation and uncertainty causing a volatile bidding climate and having received only one bid, the City placed the project on hold to allow construction costs to stabilize.

In March 2024, the project was readvertised for construction. The City awarded the Construction Contract to RC Foster Corporation on June 5, 2024, in the amount of $1,849,500
In accordance with the project specifications and the Notice to Proceed issued in July 2024, the project was required to be completed during the scheduled winter shutdown of Lester Water Treatment Plan around January 2025. The exact dates of the shutdown would be coordinated with the Operations team of the Utilities Department.

On October 18, 2024, Contract Change Order No. 1 was approved in the amount of $14,247 for additional electrical work consisting of conduit installation, trenching and backfilling work, and extension of wall sleeves for the proposed mixer vault. This change order was covered under alternative Bid Item A1 – Allowance for Field Orders.

In February 2025, the Utilities Department informed RC Foster Corporation that the winter shutdown had been postponed due to increased water demands caused by dry weather conditions and regional responses to the January 2025 Los Angeles County fires. On

April 10, 2025, RC Foster submitted Contract Change Order No. 2 for the costs incurred by the project delay due to the winter shutdown postponement.

ANALYSIS:

The change order in the amount of $176,972 is being requested to cover the costs of site demobilization, rental fees, and idle equipment on standby, extension of builders’ risk insurance, labor prevailing wage increases, and future remobilization. These costs were incurred by the postponement of the winter shutdown for the Lester Water Treatment Plant. The postponement was decided by the Utilities Department in reaction to high water demand caused by dry weather conditions and a regional response to preserve emergency water supplies due to the Los Angeles County fires in January 2025.

City staff negotiated the total change order amount down from the original request of $206,812.86. This was due to a reduction in RC Foster’s project overhead recovery expense of 75% to 46% of the total project overhead. The reduced percentage is a more accurate representation of the remaining project overhead, as RC Foster has invoiced 54% of the project budget to date.

In comparison, the cost to enter a new contract to complete the remaining work on the project would be at least $1,899,000 based on the next lowest bid in 2024 and does not include any inflation adjustment for 2025, 10% contingency, or construction support.

Additional time and administrative costs would also be required to secure a new contractor.

RC Foster Corporation has maintained a good faith relationship with the Utilities Department and has been a reliable contractor on past and current projects, including Mangular Blending Facility, Well 17A Emergency Generator, and Well 14 Rehabilitation and Equipping. Retaining RC Foster Corporation would constitute a continuation of the contractor’s familiarity with the project scope of work and site conditions. This results in time savings towards an earlier project completion compared to bringing a new contractor up to speed.

Construction is tentatively scheduled to resume in early 2026 for the next winter shutdown, with completion anticipated in the spring of 2026.

FINANCIAL IMPACT:

Funding for the recommended actions is available in the Lester Post Disinfection Station Capital Improvement Project No. UT-2013-02, within the Water Utility Fund 570.

The revised construction cost for this project is outlined as follows:

ENVIRONMENTAL ANALYSIS:

This project is categorically exempt pursuant to Section 15301(d) of the Guidelines for the California Environmental Quality Act (CEQA), which states that a project is exempt if the project involves negligible or no expansion of use to the existing facility. This project is relocating the disinfection point along an existing 30” effluent line, with no increase in capacity. A Notice of Exemption has been filed with the County of Riverside.

REQUEST FOR CITY COUNCIL ACTION
SUBJECT:

AN AMENDMENT TO THE WILDLAND PROTECTION AGREEEMENT BETWEEN THE CITY OF CORONA AND CAL FIRE TO INCLUDE AN ADDITIONAL 1476.01 ACRES EXECUTIVE SUMMARY: This staff report asks Council to approve an amendment to the Wildland Protection Agreement between the City and the California Department of Forestry and Fire Protection to include a third geographic area of coverage under agreements adopted in 2021 and 2022. This expansion will provide coordinated and costeffective wildland fire protection for areas under local jurisdiction responsibility, ensuring that specialized resources and mutual aid are available during wildland fire emergencies.

RECOMMENDED ACTION: That the City Council:
a. Approve the amended Wildland Protection Agreement for Automatic and Mutual Aid in Fire Emergency Services between the City of Corona and California Department of Forestry and Fire Protection (CAL FIRE). b. Authorize the City Manager, or his designee, to execute the amended Wildland Protection Agreement for Automatic and Mutual Aid in Fire Emergency Services between the City of Corona and California Department of Forestry and Fire Protection (CAL FIRE).
c. Authorize an appropriation in the amount of $9,637.62 to the Fire Department’s operating budget within General Fund 110.

BACKGROUND & HISTORY:

Several key terms define responsibility for wildland fire protection in Corona. The Direct Protection Area (DPA) is where a specific fire protection agency, such as the City of Corona Fire Department, is primarily responsible for responding to and managing fire suppression. The Federal Responsibility Area (FRA) covers land where federal agencies are accountable for wildland fire protection under federal law. The State Responsibility Area (SRA) is where the State of California, through CAL FIRE, holds financial responsibility for wildland fire protection. The Local Responsibility Area (LRA) includes lands where neither the state nor federal government has legal responsibility, leaving the local agency, such as the City of Corona, to provide fire protection services.

The City of Corona’s Wildland Protection Agreement (WPA) with CAL FIRE was first approved by the City Council on October 20, 2021, covering 721 acres in the Prado Basin LRA. This agreement was established in response to the significant risk of wildland fires in the area, as highlighted by the 2020 Airport Fire.

In November 2022, the WPA was amended to add a second geographic area, Eagle Valley, thereby increasing the total protected LRA acreage to 1,879 acres. The City responded to 54 fires in Eagle Valley since July 2019, and the expansion ensured that specialized resources could be requested at a predetermined cost, protecting the City from unexpected or exorbitant expenses during major incidents.

The most recent addition to the WPA is the Sierra Del Oro area, located in the southwestern city limits. This 1,476.01-acre area is within both Corona’s DPA and LRA, bringing the total WPA LRA coverage to 3,355 acres. The City remains responsible for the costs of additional firefighting resources in this area, but the amended agreement continues to provide for specialized resource requests at no extra cost beyond the terms of the agreement.

ANALYSIS:

The WPA establishes a coordinated wildland fire response plan between the City and CAL FIRE. Due to Corona’s wind-prone geography, wildland fires can quickly exceed local capabilities. When this occurs, CAL FIRE provides additional resources, which, without the WPA, would be billed at an hourly rate of approximately $50,000 for the first hour of a high-threat dispatch. The agreement is structured to enhance interagency coordination and reduce the City’s firefighting expenses, ensuring rapid and cost-effective access to critical resources during emergencies.

The City of Corona’s Wildland Protection Agreement has evolved since 2021 to address the growing risk of wildland fires by expanding coverage from the Prado Basin to Eagle Valley and now Sierra Del Oro. Each expansion has been driven by recent fire history and the need for efficient, cost-controlled access to CAL FIRE’s specialized resources, with the total WPA LRA area now at 3,355 acres. The agreement remains a vital tool for protecting the community and mitigating the financial impact of wildfires.
