AGENDA MEMO
DATE:
June 13, 2011
TO:
Mayor and Members of the City Council
FROM:
Office of the City Manager
By: John Oskoui, P.E., Director of Public Works
SUBJECT: CASH CONTRACT NO. S.S. 625 – LAKEWOOD BOULEVARD AT
COLUMBIA WAY INTERSECTION IMPROVEMENT PROJECT
AWARD CONSTRUCTION CONTRACT
RECOMMENDATION:
That the City Council:
1. Award Cash Contract No. S.S. 625 in the amount of $164,296.00 to
Bannaoun Engineers Constructors Corporation for the Lakewood Boulevard
at Columbia Way Intersection Improvement Project, and
2. Appropriate $58,339 from the Gas Tax Fund.
BACKGROUND:
Columbia Way is a Secondary Arterial roadway within the City and carries
approximately 8,000 vehicles per day (VPD). Columbia Way accommodates both sub-
regional traffic and continues to the south through the Cities of Bellflower and Lakewood
and terminates in the City of Long Beach. In addition, this street provides local access
within the City of Downey to several key attractions and destinations such as Discovery
Sports Complex, Columbia Memorial Space Center, Kaiser Medical Center, the Los
Angeles County Department of Education and the residential neighborhood on the west
side of the Street between Imperial Highway and Lakewood Boulevard.
Currently, vehicular traffic traveling southbound on Lakewood Boulevard cannot turn left
on Columbia Way due to the presence of a continuous raised median along Lakewood
Boulevard. The demand for left-turning traffic from southbound Lakewood Boulevard
onto Columbia Way has steadily increased recently due to the additions of the
Discovery Sports Complex, Columbia Memorial Space Center and Kaiser Medical
Center. This increased demand has placed a burden on other nearby intersections,
such as Lakewood Boulevard at Imperial Highway and has created neighborhood
intrusion issues, particularly, on Rose Avenue and James Street.
In order to improve overall traffic circulation, increase convenience for motorists
traveling southbound on Lakewood Boulevard destined for the aforementioned uses
along Columbia Way and decrease neighborhood intrusion, the City wishes to provide
left turn access from southbound Lakewood Boulevard onto southbound Columbia Way.

Lakewood Boulevard (as a refuge for pedestrians and for proposed traffic signal
equipment); and
Modification of existing traffic signal on Lakewood Boulevard at the Downey
