Final expenditures for the Project totaled $1,090,106.08.
The Project work performed by Calpromax Engineering Inc. is now complete and ready for City Council acceptance and authorization to release the final retention payment amount of $54,505.30 to the contractor upon expiration of the 35-day lien period and there being no claims filed.
BACKGROUND
The Project included signal control replacements and traffic control upgrades at the following intersections along Artesia Boulevard:
• Artesia/Aviation Way
• Artesia/Green
• Artesia/Rindge
• Artesia/Slauson
• Artesia/Vail
• Artesia/Mackay
• Artesia/Felton
The Project’s design was completed in 2024, and City staff coordinated the Project with personnel in the Los Angeles County Public Works Department, who maintain the signals along the Blvd. The following upgrades were performed at each of the identified intersections:
• Replaced aging signal controllers and conflict monitors with current LA County standard
• Replaced aging and unreliable video detection systems
• Rewired traffic signal cabinets
• Replaced older protected-permissive 5-section left-turn signal heads with modern 4-section flashing yellow arrow (FYA) left-turn signal heads
• Replaced all internally illuminated street name signs and traffic signal safety lights
• Replaced existing U-turn signs
• Replaced all pedestrian signal heads and push buttons with modern standard equipment
• Added yellow retroreflective tape to all existing signal heads per current practice
• Associated signage replacements
• Installed new bicycle blue light detection feedback at Artesia/Rindge
• Constructed significant median modification at Artesia/Rindge to improve line of sight
• Revised signal timing with leading pedestrian intervals (LPI) and time-of-day based FYA operations based on collision history
On September 17, 2024, the City Council awarded Calpromax Engineering Inc., a public works contract for $1,041,335 for the work. The field work for the Project commenced on September 15, 2025, after all equipment was procured and received. The delivery of new traffic signal controllers, experiences long lead times of six months or more, and additional coordination was required with Los Angeles County Public Works to test and receive the approved controllers. On March 24, 2026 the Project field work was reviewed by City and County staff. All punch list items were addressed as of June 30, 2026 and the Project was determined to be complete.
During construction, staff issued two change orders totaling $48,771.08, which addressed additional signage replacements, additional pedestrian signal head replacements, and unforeseen conduit and rebar removal. These change orders brought the final contract amount to $1,090,106.08.
Staff recommends that the City Council accept the Project as complete and authorize release of the final retention payment of $54,505.30 to the contractor upon expiration of the 35-day lien period assuming no claims are filed.
