TITLE:
Approval of Additional Construction Contingency with Jilk Heavy Construction, Inc., and Amendment No. Six to the Professional Services Agreement with Burns & McDonnell Inc. for the San Diego Trash Interceptor Project (Contract No. 7127-3) ABSTRACT:
The San Diego Creek Trash Interceptor Project, a.k.a. the Newport Bay Trash Wheel, is completed but requires a number of fabrications, in-field changes and additions. Staff seeks City Council approval of additional construction contingency funding of $270,163 for the Jilk Heavy Construction, Inc. contract and of Amendment No. Six to the Burns & McDonnell Inc. Professional Service Agreement to increase the contract’s not-to-exceed amount by $25,482 to pay for additional design and deputy welding inspection services.
RECOMMENDATIONS:
Find the requirement for environmental review under the California Environmental Quality Act (CEQA) is satisfied by the September 25, 2018 Council adoption of Resolution No. 2018-67, A Resolution of the City Council of the City of Newport Beach, California, Adopting Mitigated Negative Declaration No. ND2018-002 (SCH No. 2018081013) for the Newport Bay Water Wheel Project (PA2018-153), pursuant to the California Environmental Quality Act, State CEQA Guidelines and City Council Policy K-3;
Approve Budget Amendment No. 26-009 appropriating $307,645 of increased expenditures in Account No. 16001-980000-17X12 (Newport Bay Trash Wheel) from the Environmental Liability Fund unappropriated fund balance; Increase the construction contingency by $270,163 for the Jilk Heavy Construction, Inc. Contract No. 7127-5 for a total contingency of $668,163 (approximately 17% of the contract award) for the San Diego Creek Trash Interceptor project; and Approve Amendment No. Six to the Professional Services Agreement with Burns & McDonnell Inc. (Attachment B) for construction services to increase the Agreement amount by $25,482 for a total not-to-exceed amount of $913,692 and authorize the Mayor and City Clerk to execute the Amendment.
DISCUSSION:
The San Diego Creek Trash Interceptor project consists of a custom-made floating trash wheel, a rail system, and landside improvements that provide truck access to dumpsters located on a rail sled. The trash wheel is a moored vessel that uses booms to move trash toward rotating rakes that carry floating trash and debris onto a conveyor belt that then moves the trash up and into two dumpsters that sit within a sled mounted to a short rail system. Once the dumpsters are full, the dumpster sled is winched landward, and the dumpsters are emptied by a standard front-loading refuse truck.
Solar panels on top of the trash wheel charge batteries that power submerged pumps that pump San Diego Creek water into the vanes of the water wheel causing the wheel to turn. The turning water wheel, through a gear box system, powers the trash rakes and conveyor belt.
In February of this year, the trash wheel, rail system, and landside improvements weathered a large, 10-year storm event without damage. Though it was still under construction, the City of Newport Beach’s contractor, Jilk Heavy Construction (Jilk), operated the trash wheel and captured approximately 50 to 60 cubic yards of trash and debris. It is expected that there will be a significantly larger trash and debris capture next year.
Jilk, based on its expertise constructing marine facilities, designed and built the trash wheel with design assistance from Clearwater Mills, the inventor of the trash wheels in Baltimore Harbor. Throughout the design and fabrication process, many upgrades and modifications were necessary due to the Newport Bay Trash Wheel being much larger than the Baltimore trash wheels. The trash wheel components that needed modifications included the custom-built conveyor, power transmission, electrical system, pump system, skeletal structure and canopy, and solar panel system. In addition, City staff requested upgrades to lighting, cameras and the SCADA (Supervisory Control and Data Acquisition) system. The total increase in cost for these items is $270,163. Jilk has provided staff complete backup information on its design time and costs, material and equipment costs, and fabrication and installation costs.
Jilk created a trash wheel that is structurally stronger than its Baltimore cousins and incorporated design enhancements to facilitate maintenance and operation. The project was substantially completed by May 2025.
Additional services were also necessary and provided by Burns & McDonnell Engineering Company (Burns & McDonnell) and its subconsultants totaling $25,482 in additional costs, including:
$18,000 for additional welding inspection by a certified deputy inspector, $ 4,957 for structural design modification of the catwalk to accommodate tidal movement of the canopy frame, and $ 2,525 for administrative costs.
The proposed amendment to the City’s professional services agreement with Burns & McDonnell is included as Attachment B.
Finally, $12,000 needs to be allocated to the City’s IT Division to install and setup network equipment for remote monitoring and control of the trash interceptor.
FISCAL IMPACT:
Upon approval of the proposed budget amendment (Attachment A), sufficient funding is available from the Fiscal Year 2025-26 Capital Improvement Program budget for completion of these contracts. The funds will be expended from the following account:

The Environmental Liability Fund Fees (ELFF) are authorized for use by the City for any expense associated with a City-hired commercial hauler recycling, diverting or disposing of trash collected in the city to fulfill State, federal or local law requirements. In this case, State regulations, promulgated in 2015, require heightened trash capture and removal. Construction of the trash interceptor facility allows access for one of the City’s commercial trash haulers to collect and dispose of the trash captured in San Diego Creek and is therefore eligible for funding from the ELFF program, which currently has approximately $10 million in reserves.
ENVIRONMENTAL REVIEW:

San Diego Creek Trash Interceptor, pursuant to the California Environmental Quality Act, State CEQA Guidelines and City Council Policy K-3.
