On September 28, 2021, by Resolution No. 2021-378, Council approved a Sole Source Purchase Agreement with Muniquip for Wemco/Hidrostal pump parts and electrical components, for a two-year Agreement with three one-year extension options, for an annual estimated amount of $16,000, and a total amount not to exceed $80,000, over five-years, and authorizing the Purchasing Manager, or her designee, the ability to add parts based on the department’s needs, ensuring the total amount does not exceed the authorized total.
DISCUSSION:
On February 23, 2026, the City Manager authorized the Utilities Department to solicit procurement for Wemco/Hidrostal pumps, pump parts and electrical components. The agreement will provide the pumps and pump components necessary to support the continued operation, maintenance, and reliability of the City’s wastewater collection system. These pumps and pump components are utilized in Hidrostal submersible slide rail pumps located throughout the City’s infrastructure and include pumps, pump rebuild kits, impellers, mechanical seals, electrical components, power cords, suction bells, slide rail brackets, slide rail bases, and other critical replacement parts.
Additionally, the need for replacement parts for these pumps has increased since the last agreement was in place. To avoid significantly higher costs associated with complete pump replacement, staff utilizes rebuild kits and replacement components as part of its preventative, predictive, and corrective maintenance program. As the equipment continues to age, timely access to these components is essential to extend equipment life, minimize emergency repairs and downtime, maintain system reliability, and reduce the risk of costly pump failures.
Modesto Municipal Code Section 8-3.203 generally requires all purchases, which meet or exceed $100,000 for material, equipment, or contractual services to follow formal bid procedures. However, MMC 8-3.204(b) provides that a purchase may be exempted from the City’s formal bidding requirement where the Purchasing Agency’s requirements can be met solely by a single article or process. Therefore, staff recommends the purchase of Wemco/Hidrostal pump parts and/or electrical components from Muniquip LLC should be exempt from the formal bidding procedures in accordance with Modesto Municipal Code 8-3.204(b) since Muniquip LLC is the exclusive authorized representative for Hidrostal Pumps and parts.
FISCAL IMPACT:
Expenditure over the past five (5) years for pump parts and electrical components under the previous agreement are listed below:

Agreement with Muniquip LLC for Wemco/Hidrostal Pump Parts and/or Electrical Components
PREVIOUS AGREEMENT EXPENDITURES:
Agreement Year Sub Total

Year 2 (2022-23) $ 10,116

Year 4 (2024-25) $ 12,396
Year 5 (2025-26) $ 13,726
TOTAL $ 74,485
Some of our larger pumps are over $100k to replace. Out of concern that it would have caused staff to exceed the Council approved Agreement amount, the purchase of pumps was not included in the previous 5-year Annual Agreement but were purchased as needed with a Standalone Purchase Order. However, staff would like to add the ability to purchase pumps in the new 5-year Agreement and have increased the new Agreement amount since staff could easily exceed an annual estimated amount of $150k a year if multiple failures occur at the same time. Below is the past five (5) year expenditure for pumps that was not included in the Agreement and the total combined between Standalone Purchased Orders Expenditures and the Previous Agreement Expenditures.

ANTICIPATED AGREEMENT EXPENDITURES:
The table below contains projected spending for the next five years, with years one and two fixed. The overall agreement total was calculated by forecasting the Consumer Price Index (CPI) percentage increases based on average of the CPI index over the last twelve (12) months. City staff project annual increases based on this estimated forecast. Annual increases will be calculated using the current CPI index at the time of the requested increase. Additionally, the Wastewater Division will have two (2) new pump stations that will be going into operation and will need to be covered by this agreement.

California Levine Act Disclosure
California Government Code Section 84308, also known as the "Levine Act", prohibits City “officers” from participating in any action related to a license, permit, or other entitlement for use (a “proceeding”) if such member accepts, solicits, or directs political contributions from a party to the proceeding or their agent totaling more than $500 while the proceeding is pending before the agency, and for twelve (12) months following the date a decision concerning the proceeding has been made.

Nick Bavaro, Vice Chair
Eric Alvarez, Member
THROUGH: Joseph P. Lopez, City Manager
FROM: Chad Reed, Director of Public Works
SUBJECT: Second Amendment to the Agreement with HDR Engineering, Inc to Complete Assigned Work and Gain Regulatory Compliance for the Carpenter Road Landfill
CONTACT: John Chavez, Integrated Waste Manager, jchavez@ modestogov.com, 209-577-5453
DESCRIPTION:
Consider the Second Amendment with HDR Engineering, Inc., of Folsom, CA to complete assigned work and to gain Regulatory Compliance for the Carpenter Road Landfill, Modesto California, thereby increasing the Agreement amount by $820,774 and forwarding to Council for approval. (Funding Source: Carpenter Road Landfill) STRATEGIC PLAN ELEMENT:
The recommended action supports the City’s 2025-2026 Strategic Plan Area of Focus:
Goal B: “Increase pride in Modesto’s diverse neighborhoods and business districts through strategy 1: Invest in beautification efforts and by investing in community assets and amenities.”
BACKGROUND:
The City of Modesto owned and operated the Carpenter Rd Landfill from 1956-1968. It was a pre-Subtitle D landfill, which means there was never a liner put in, or gas and leachate control systems. The landfill size is thirty-nine acres and is split into two areas, east and west, bordering Carpenter Road. The City has ensured post-closing monitoring of water and gas wells, as well as general maintenance as required under State law. In the mid-2000’s there was a spike in one methane gas well, as well as a release of Volatile #4..

Economic Development Committee, August 3, 2026
Second Amendment to the Agreement with HDR Engineering, Inc to Complete Assigned Work and to Gain Regulatory Compliance for the Carpenter Road Landfill
Organic Compounds (VOC’s). The Regional Water Quality Control Board (Water Board) mandated the City to provide a Mitigation and Monitoring Plan, as well as a Corrective Action Plan. In 2015 the Water Board issued a Cleanup and Abatement Order (CAO) to the City based on their approval of the Correction Action Plan. The City agreed to cleanclose the east fill and move all the waste to the west fill. The idea behind this would be that all the waste would be contained in one area on the west side and a culvert and pipe would be placed to capture water runoff that would drain into a clean retention basin on the east side. The Water Board accepted this plan. The City conducted an initial study for a mitigated negative declaration and all agencies that were required to be notified were notified. Construction was planned to begin in 2016-2017, however, unusually wet weather delayed the project by approximately one year.
The City then went out to bid in 2018 and on August 14, 2018, by Resolution No. 2018- 345 Council awarded the project to Pacific States Environmental Contractors, Inc. of Dublin, CA. Construction began in 2018 and by August 2020, observable waste, and impacted soil from the Eastern Waste Management Unit (WMU) was removed and consolidated into the Western WMU, and a new soil cover was installed atop the Western WMU. A stormwater retention basin was constructed in the former Eastern WMU location, and documents were submitted to the Water Board regarding closure. The Water Board contends that the documents are not complete, and subsequent submittal of additional information did not completely satisfy the requirements of the CAO. The Water Board has provided notice that the City remains non-compliant with the CAO and that it may be subject to significant civil penalties until the delinquent reports are resolved.
On September 12, 2023, by Resolution No. 2023-412, the City entered into an agreement with HDR Engineering, Inc., of Folsom, CA to complete assigned work and to gain regulatory compliance for the Carpenter Road Landfill, Modesto California for an amount not to exceed $271,700 over a five-year period, plus $27,170 for additional services authorized by the City Manager, for a total amount not to exceed $298,870.
On June 24, 2025, the First Amendment to the Agreement was approved via Council Resolution No. 2025-238, to complete assigned work and to gain regulatory compliance, and to increase the amount of the Agreement to $351,450. This Amendment was needed for cost associated with trenching that would take place on the South end of the landfill adjacent to the Tuolumne River. The purpose of this trenching was to identify and locate any residual waste so that it may be removed, allowing Post Closure Maintenance Plan to continue and regulatory compliance achieved.
DISCUSSION:
This Second Amendment is necessary to complete regulatory compliance activities required by the State Water Resources Control Board and associated permitting agencies so the City of Modesto can resolve outstanding compliance obligations at Carpenter Road Landfill.

Second Amendment to the Agreement with HDR Engineering, Inc to Complete Assigned Work and to Gain Regulatory Compliance for the Carpenter Road Landfill
HDR Engineering, Inc. reviewed the existing CAO received from the Water Board and the supporting documents provided by the City. The tasks listed below are outlined in the original Agreement to address the Water Board’s requested work and to ensure compliance.
Phase 1
Task 100 Project Management
Task 200 Site Reconnaissance and Kickoff Meeting
Task 300 Cover Completion Confirmation Work Plan
Task 400 Stormwater Repair and Protection Work Plan
Task 500 Residual Waste Removal Work Plan
Task 600 Clean Closure Results Discussion
Task 700 Post-Closure Maintenance Plan (PCMP)
HDR Engineering, Inc. is currently working on all the tasks mentioned in Phase 1. The request to amend the Agreement is regarding Task 500: Residual Waste Removal Work Plan. The plan is to remove the waste materials that are located on the banks of the Tuolumne River. To conduct any work at the location, the City needed to obtain a permit from the California Department of Fish and Wildlife (CDFW). In October 2024, the City submitted an application to obtain a Lake or Streambed Alteration Agreement. On February 28, 2025, CDFW issued an Operation of Law letter stating that because they did not respond to the City by January 31, 2025, an agreement is not required. However, the City is still obligated to complete the project as exactly described in the application without an agreement.
The CDFW permit indicated that the City is responsible for complying with certain biological monitoring requirements such as Fish and Game Code sections 2080, 1908, 3511, 4700, 5050, and 5515, and other sections mentioned in the notice. Also, the Water Board indicated that the City is required to excavate additional trenches by the riverbank.
With the above requirement, the City is requesting a Second Amendment to the current Agreement with HDR Engineering, Inc.
In September 2025, HDR submitted a Cover Repair Alternatives Analysis and cost estimate,
presenting four alternatives to achieve cover density and moisture content requirements for the
landfill cover and for removal of residual waste. This proposal is based on the City’s selection of
cover mitigation alternative 2 to reconstruct the soil cover and remove residual waste The following tasks have been identified to complete Residual Waste Removal Work Plan:

Thus, HDR has started the process to obtain a CDFW permit requited to complete the original scope of work, this amendment is necessary to conduct biological monitoring as required for the CDFW permit. #4..

Subject: Proposal for Cover Repair Design, Contract Administration and Construction Quality Assurance Services, with Residual Waste Removal Permitting and Oversight
Carpenter Road Landfill, Modesto, CA
Dear Mr. Chavez,
In accordance with our April 6, 2026, meeting and our correspondence through May 27, 2026, HDR has prepared this scope of services at your request to facilitate regulatory compliance for the Carpenter Road Landfill (Landfill). The Central Valley Regional Water Quality Control Board (Water Board) has notified the City of Modesto (City) that the Landfill cover does not meet soil compaction standards, that the stormwater management system and the southern slope stabilization of the closed landfill need to be improved to meet regulatory requirements, and that waste observed between the southern landfill boundary and north of the Tuolumne River (residual waste) requires excavation and disposal before certification for landfill closure. The City has requested this scope of work from HDR to resolve these noncompliance items.
1.0 Background
The City owns and maintains the former Carpenter Road Landfill, regulated by the Water Board.
The Landfill site is approximately four miles southwest of the City along Carpenter Road, immediately north of the Tuolumne River. The Landfill formerly included two individual unlined waste management units (WMUs), the Eastern WMU and the Western WMU, split geographically by Carpenter Road.
In 2015, the Water Board issued CAO R5-2015-0700 directing the City to address landfillrelated groundwater impacts along the Tuolumne River and to clean-close the Eastern WMU by relocating its waste to the Western WMU. The order also required the City to install a final cover over the Western WMU, construct a stormwater retention basin, and submit reports demonstrating completion of the required CAO tasks.
Between August 2019 and March 2021, observable waste and impacted soil from the Eastern WMU were removed and consolidated into the Western WMU, and a new soil cover was installed atop the Western WMU. A stormwater retention basin was constructed in the former Eastern WMU location, and documents were submitted to the Water Board regarding closure.
The Water Board contends that the documents are incomplete, and that the subsequent submittal of additional information, as recently as January 25, 2023, by others on behalf of the City did not fully satisfy the requirements of the CAO. The Water Board was not in receipt of #4..

City of Modesto | Proposal
Cover Repair Design, Contract Administration and Construction Quality Assurance Services compaction or physical property testing of the installation of the Western WMU cover and requested that verification testing be performed.
In April 2024, HDR prepared a Stormwater Repair Work Plan that presented the results of hydraulic modeling intended to assess the potential for final cover erosion during a 100-year, 24-hour precipitation event and to evaluate surface water elevations and velocities along the southern slope of the WMU from a 100-year flood event on the Tuolumne River.
In May 2024, HDR performed post-WMU cover installation Construction Quality Assurance (CQA) testing and observations to document the construction of the final cover at the Carpenter Road Landfill. The CQA testing documented that the cover soil met the requirements for 100% passing 3 inches and the minimum soil cover thickness. However, the minimum requirement of achieving soil cover compaction at 95% of the maximum dry density was not met across the three lifts, with the lowest lift having the lowest average compaction.
In August 2025, HDR excavated twelve trenches to assess the extent of residual waste on the south side of the site, abutting the Tuolumne River. The findings indicated that approximately 1,660 cubic yards of waste and soil were present in the vicinity of two co-located trenches.
In September 2025, HDR submitted a Cover Repair Alternatives Analysis and cost estimate, presenting four alternatives to achieve cover density and moisture content requirements for the landfill cover and for removal of residual waste. This proposal is based on the City’s selection of cover mitigation alternative 2 to reconstruct the soil cover and remove residual waste.
2.0 Scope of Services
The scope and deliverables presented herein address the Water Board’s requested work as presented in its letter dated April 6, 2026.
Task 800: Kick-off Meeting and Project Management
HDR will schedule and facilitate a kick-off meeting within two (2) weeks of receiving the notice to proceed. The meeting will cover both technical and administrative project items with key team members. Throughout execution of the tasks described in this scope, HDR will support the taskspecific activities through coordination of team members, meetings, communication, reporting, and quality controls. This task has been established in recognition that these activities transcend individual tasks; are required for effective project execution; may require flexibility in timing, extent, and response to project needs; and cannot always be precisely predicted or assigned to a single activity.
This task includes communication between the City and HDR; planning, organizing, and monitoring project team activities; attending meetings, as requested; responding to specific requests not specifically addressed in the scope; and preparing and updating project schedules.

During the same field visit, an HDR wildlife biologist will conduct habitat assessments for specific listed species that may occur. During the same field visit, an HDR arborist will document trees in the work area that may require removal. • The work area and design of the project will be defined before HDR biologists conduct their field work and analysis for the permit applications. • The City will coordinate access to the work area.
• Inaccessible areas will be delineated via desktop.
• HDR will finalize the deliverables after receiving 1 round of comments from the City. If additional iterations of the deliverables are needed per the City’s request, an amended scope and fee would be required.
• Permit reviews and approvals by resource agencies like USACE, RWQCB, and CDFW will require approximately 9-15 months.
Task 1400: Waste Removal Oversight and Reporting
The objective of this activity is for HDR to assist the City with its compliance obligations required by the resource agencies’ permits it will likely obtain for the residual waste removal and site restoration. These compliance obligations will likely consist of the following activities:
a) Environmentally Sensitive Area Fencing Oversight: Environmentally sensitive areas identified by the HDR biologist will be avoided during project activities. These areas will be temporarily fenced and/or flagged as close to work limits as feasible. Fencing or flagging will be high-visibility and left in place for the duration of the project. The location and extent of fencing/flagging will be determined by the HDR Biologist, who will observe its installation and conduct regular inspections. The HDR biologist will demarcate the fencing location in the field with stakes and flagging. Fencing will delineate riparian habitat, nests, elderberry shrubs, pond turtle nests, or other sensitive resources. b) Conduct Worker Environmental Awareness Training: Before the onset of work activities, an HDR biologist will prepare and conduct mandatory contractor/worker environmental awareness training for personnel to inform them on the locations of sensitive biological #4..

City of Modesto | Proposal
Cover Repair Design, Contract Administration and Construction Quality Assurance Services resources and site-specific protective measures required during construction activities. If new personnel are added to the project, the City will require them to receive the mandatory training before starting work. Training will cover special-status species, including species identification, life-history descriptions, habitat requirements at various life stages, and the species’ protected status. The training is expected to be no more than 15 minutes and will be conducted before excavation activities. c) Nesting Bird and Raptor Surveys: Before work that will occur between March 1 and August 15, an HDR biologist will conduct pre-construction surveys for tree-nesting raptors and migratory songbirds. Nesting habitats for tree nesting raptors and migratory songbirds will be surveyed within 250 feet of the proposed construction areas. The HDR biologist will conduct Swainson’s hawk surveys per guidelines provided in the Recommended Timing and Methodology for Swainson’s Hawk Nesting Survey in the Central Valley (Swainson’s Hawk Technical Advisory Committee 2000). d) Pond Turtle Nesting Survey: Within 48 hours before project activities, a survey will be conducted for the presence of pond turtles. If nesting pond turtles are detected, exclusionary fencing in the vicinity of the nest will be used to reduce the potential for pond turtles to encroach into the work area. This fencing will be maintained throughout the duration of construction in the vicinity of the nest. The integrity of the exclusion fencing will be checked daily by a biological monitor or a designee. Additionally, HDR’s biological monitor will check the work area each morning before construction begins to confirm that no turtles are within the exclusion area. If an individual or nest is observed in the impact area, construction activities will stop until the biological monitor establishes an appropriate buffer or the turtle is no longer in the impact area. e) Roosting Bats and Maternity Colony Survey: If ground disturbing activities commence on the project site during the breeding season of native bat species (April 1 to August 31), a field survey shall be conducted by a qualified bat biologist to determine whether active roosts are present on site or within 50 feet of the project boundaries, including visual and acoustical surveys.
Field surveys shall be conducted early in the breeding season before project activities begin, when bats are establishing maternity roosts but before pregnant females give birth (April through early May). If no roosting bats are found, then no further mitigation is required. If roosting bats are found, then disturbance of the maternity roosts shall be avoided by halting project activities until the end of the breeding season, or a qualified bat biologist removes and relocates the roosting bats in consultation with CDFW through a separate permit application process. Tree removals with habitat for bats will follow the 2-day method of removal, which includes branch limbing on day 1 and trunk felling on day 2, and will be monitored by a qualified biologist.
f) Burrowing Owl Survey: Within 15 days before project activities, a survey for burrowing owls will be conducted between March and May. Fossorial mammal burrows within the work area will be examined for signs of occupation by burrowing owls including the presence of pellets, whitewash around the opening, or scattered feathers. If burrowing owls are detected, no work will occur until the burrowing owls leave or an Incidental #4..
