The completed San Diego Creek Trash Interceptor (Trash Interceptor) project consists of
a floating trash wheel, rail system and landside improvements that provide truck access
to the dumpsters located on the rail sled (Attachment A). The trash wheel is a moored
vessel that uses booms to move trash toward the trash wheel where rotating trash rakes
convey 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 emptied by
a standard front -loading trash truck.
Power for the floating trash wheel is provided by solar panels on top of the trash wheel.
The solar panels charge batteries, that in turn, power submerged pumps to pump creek
water into the vanes of the water wheel causing the water wheel to turn. The turning water
wheel powers the trash rakes and the conveyor belt. Landside power for the lights,
cameras, rail sled winch, and sliding entrance gate, is provided by a separate array of
solar panels located at the top of the creek bank.
While still under construction, the Trash Interceptor was able to be operated and captured
approximately 50 to 60 cubic yards of trash and debris during the last half of the rain
season from February through April 2025. It is anticipated that during the upcoming full
rain season, the Trash Interceptor will remove over 200 cubic yards of material from San
Diego Creek.
The contracted work has now been completed to the satisfaction of the Public Works
Department. A summary of the construction cost is as follows:

Final Contract Cost:
$ 3,981,074.00
$ 3,981,074.00
$ 663,752.56
$ 4,644,826.56
The final total contract amount was $4,644,826.56, approximately 16.7% higher than the
original bid amount. Given the project's complexity and the pilot -project nature of the
Trash Interceptor installation, City of Newport Beach (City) staff, the designer, and the
contractor refined the design during construction to improve reliability and resilience,
which increased costs. Upgrades and design modifications were implemented on the
trash wheel's power transmission system, custom-built conveyor, electrical system, pump
system, skeletal structure and canopy, solar panel system, site lighting, cameras and
SCADA (Supervisory Control and Data Acquisition) system. To accommodate City -
requested design changes, 276 additional working days were granted to the contractor.

$ 1,182,326.56
Total: $ 4,644,826.56
Contributions were received from the Ocean Protection Council and the State of
California.
Measure M2 funds are provided by OCTA through their Project X "Environmental Clean
Up" program. OCTA established and is administering an environmental cleanup grant
funding program to address water quality degradation associated with transportation -
generated pollution.
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, recovering
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.

On July 11, 2023, City Council found the requirement for environmental review under the
