ACTION(S):

SUMMARY:
Approval of the Cooperative
Agreement for Funding and Maintenance of the Adams Avenue Bridge over the Santa
Ana River and Greenville Banning Channel and adoption of a resolution to
declare portions of Adams Avenue to be a County of Orange highway will allow
the County of Orange to complete necessary maintenance on Adams Avenue Bridge.
BACKGROUND
INFORMATION:
Adams Avenue Bridge (Bridge) over the
Santa Ana River and Greenville Banning Channel was constructed by the County of
Orange (County) in 1977. The western portion of the Bridge is within
unincorporated Orange County, while the eastern portion of the Bridge over
Greenville-Banning Channel is within the jurisdiction of the City of Costa Mesa
(City). Preventative bridge maintenance, including handrail repair and
replacement of joint seals, is currently needed.
Prior Board of Supervisors (Board) actions
supporting the spending of County Road funds to operate, maintain and improve
the Lower Santa Ana River bridges, which include Adams Avenue, are summarized
in the table below.

Board
Date |
Action |
|
12/5/2000 |
Approved Notice of Completion for
seismic retrofit of the Bridge over the Santa Ana River. |
|
5/21/2013 |
Approved Final Initial Study/Mitigated
Negative Declaration (IS/MND) IP No. 11-444 Countywide Long-Term Routine
Maintenance Permitting Program. |
|
4/8/2014 |
Approved plans and specifications for
maintenance of various bridges in Orange County, including the Bridge over
the Santa Ana River. |
|
5/20/2025 |
Approved the FY 2025-26 Capital
Improvement Programs and SB 1 Eligible Project List. |
Since a portion of the Bridge is within
the City’s jurisdiction, a cooperative agreement is necessary to allow the
County to perform maintenance activities on the entire Bridge. The cooperative
agreement includes a provision to designate the portion of Adams Avenue within
the City’s jurisdiction as a County highway, thereby authorizing OC Public
Works to perform maintenance utilizing County Road funds on the entire Bridge
in accordance with the provisions of Streets and Highways Code (SHC) Sections
1700-1703. While SHC Section 1704 allows the County to return jurisdiction to
the City upon filing the Notice of Completion, the County will retain
responsibility for the entire Bridge due to its Countywide significance. This
includes continued operation, maintenance and improvement of both the western
portion in unincorporated Orange County and the eastern portion previously
under the City’s jurisdiction. The County Road Index will be updated to include
the newly designated segment.
On September 16, 2025, the City Council
approved the proposed Cooperative Agreement MA-080-26010143 (Cooperative
Agreement).
OC Public Works recommends the Board
approve Cooperative Agreement with the City for Funding and Maintenance of the
Bridge, effective upon execution of all necessary signatures, until the filing
of the Notice of Completion; and adopt a Resolution to declare those portions
of Adams Avenue that are within the city limits of Costa Mesa, to be a County
of Orange highway for the purposes of construction, improvements and
maintenance.
Compliance
with CEQA: This
Project is a necessarily included element of the project considered in the
Final IS/MND IP No. 11-444 Countywide Long-Term Routine Maintenance Permitting
Program, adopted by the Board on May 21, 2013. No substantial changes have been
made in the project, no substantial changes have occurred in the circumstances
under which the projects are being undertaken and no new information of
substantial importance to the project which was not known or could not have
been known when the Final IS/MND IP No. 11-444 was approved has become known;
therefore, no further environmental review is required.
