AGENDA REPORT
DATE: January 28, 2002
TO: Honorable Mayor and City Council
THRU: John B. Bahorski, City Manager
FROM: Doug Danes, P.E., Director of Public Works, City Engineer
SUBJECT: APPROVAL OF PLANS AND SPECIFICATIONS FOR
MARINA DRIVE BRIDGE REHABILITATION, PROJECT No.
49676
SUMMARY OF REOUEST:
The proposed City Council action will approve the plans and specifications, and authorize Staff
to initiate the bidding process so that a contract may be awarded for the Marina Drive Bridge
Rehabilitation Project.
The Marina Drive Bridge Project is a joint project between the City of Seal Beach and the City
of Long Beach with the City of Seal Beach being the lead agency. The proposed project will
demolish the existing Marina Drive Bridge, which crosses over the San Gabriel River,
connecting into the City of Long Beach and construct a new cast- in- place/prestressed concrete
box girder bridge. In addition, street improvements will be implemented on Marina Drive from
First Street to the Bridge. The existing bridge has been determined to be subject to collapse if
subjected to a major earthquake, and therefore is designated for replacement under the State of
California Seismic Safety Retrofit Program and the Federal Highway Bridge Replacement and
Rehabilitation Program. The existing bridge was originally constructed in 1938 with a 13 span
timber deck structure with concrete pile bents.
The work will consist of two construction phases. Construction will first begin on the south half
of the roadway and bridge, keeping the north half open to pedestrian/bicycle and vehicle traffic.
Upon completion of the south half of the new bridge, the contractor will move to the north half
and open traffic to the south half of the bridge. It is anticipated that the construction will last 24-
32 months. Although this method of construction increases the length of time to construct the
new bridge, it was determined to be more beneficial to the public to keep the bridge open to
traffic during construction.
The end product will be a new structurally sound roadway and bridge that will include a new
fishing pier, sidewalks, bicycle lanes, street lighting and a new landscaped median. The new
bike lanes will connect to the proposed regional bicycle facility on Marina Drive, which is
anticipated for construction this spring. ,

Highway Administration, California Department of Transportation and the County of Los
Angeles Department of Public Works Flood Control District. Long Beach City staff has
reviewed the project and it will go to the Long Beach City Council for concurrence in February
2002. The project has been formally reviewed and conditioned by California Coastal
Commission. They have issued a Notice of Intent to Issue a Coastal Commission permit and the
City will secure the permit prior to construction. The Army Corp of Engineers has also reviewed
the permit and they will issue their permit following the Coastal Commission permit issuance.
