DATE: January 26, 2004
TO: Honorable Mayor and City Council
THRU: John B. Bahorski, City Manager
FROM: Douglas A. Dancs, P.E., Director of Public Works /City Engineer
SUBJECT: SEAL BEACH BOULEVARD AND I -405 BRIDGE APPROACH
WIDENING DESIGN UPDATE - RECEIVE AND FILE
SUMMARY OF REQUEST:
The proposed action will receive and file the design update for the Seal Beach Boulevard and
Interstate 405 Bridge Approach Widening Project No. 49750.
BACKGROUND:
In May of 2003, the City obtained Caltrans approval for the Project Study Report/Project Report
(PSR/PR) for the Seal Beach Boulevard and Interstate 405 Bridge Approach Widening Project
No. 49750. This project report identifies the first phase of the project that will widen the existing
exit ramps to provide for an additional right turn lane, widen the ramp intersections to provide
dual left turn lanes, and widening of the I -405 over crossing approaches. This phase will prevent
both the North and South intersections of I -405 & Seal Beach Blvd. from reaching a level of
service F in 2025. The current LOS at the existing intersections is C/D and the proposed
improvement will improve traffic flow to a LOS of B /C.
As identified during the third quarter of 2003, the Department's monthly Capital Improvement
Project progress report given to Council outlined that the phased approach. This course of action
was pursued because of the uncertainty of future freeway improvements impacting this bridge
during the process and lack of funding for reconstructing the bridge required accommodating the
bridge widening for three lanes in each direction. Recent correspondence from OCTA has
mentioned that impacts to the facility would not happen until 2020. If the widening were
constructed now, this would give the facility less than a 20 -year life since the future project
would need again to replace the bridge. The current cost to accommodate both the widening and
the lengthening for the future HOV project is estimated at $14,000,000. It is still the intent of the
City to widen the bridge to three lanes each direction even if there is no freeway project or traffic
conditions warrant it sooner. The City would apply for potential federal funding as it becomes
available or opportunities may be available if the 405 Freeway is widened and OCTA is
currently undertaking a Major Investment Study.
Agenda Item 1/
Proposals were requested from consultants for the revised design of the project and the firms
were then interviewed. Robert, Bein and Frost Consulting (RBF), who also prepared the original
PSR/PR, emerged as the top candidate with highest ranked qualifications, related experience in
these types of projects, and an appropriate schedule. RBF Consulting comes highly
recommended from various other public agencies, and are currently performing work for
agencies in Orange County. Staff will use the existing City contract with RBF for the design of
this facility and staff will negotiate a task order proposal with RBF and their firm can perform
the work immediately within the budget set forth in the approved Capital Improvement Program
and the Engineering Division's internal budget. Award of a construction contract is expected in
the Spring of 2005.
FISCAL IMPACT:
Funds are available within the Project No. 49705 of the approved Capital Improvement Program.
The estimated cost of the project is $3,500,000 which is funded by OCTA secured grants and
traffic impact fees for the Bixby Development. No additional work will be performed unless
adequate funding is available in the project budget. Any funds remaining at the end of this phase
of the project will be used for the next phase of the project.
RECOMMENDATION:
It is recommended that the City Council receive and file the design update for the Seal Beach
Boulevard and Interstate 405 Bridge Approach Widening Project No. 49750.
