On December 15, 2009, the City Council awarded Cash Contract No. S.S. 599 to Sialic

Safety Enhancements Project in the amount of $2,981,662.
The Imperial Highway Traffic Throughput and Safety Enhancements Project entailed
improvements along Imperial Highway between Paramount Boulevard and the west city
limit and between Bellflower Boulevard and the east city limit to increase vehicle
throughput, enhance traffic safety and improve the aesthetics and visual appearance of
the Imperial Highway Corridor. The first phase of this project which included the portion
of Imperial Highway between Bellflower Boulevard and Paramount Boulevard, was
completed in August 2007.
DISCUSSION:
As of March 31, 2011, all work under Cash Contract No. S.S. 599 has been completed
per previously approved plans and specifications and to the satisfaction of the City.
Thus, the project is deemed complete, and staff recommends releasing the remaining
contract funds (retention) to Shawnan.
The second phase of the Imperial Highway Traffic Throughput and Safety Enhancements
Project included the following elements and features:
Construction of new raised landscaped median islands within the project limits;
New landscaping of the existing median islands within the project limits;
