Department Recommendation:
Staff recommends that the City Council authorize the City Manager to file a Notice of Completion for the Battery Backup System & Traffic Signal Preemption Project.
Background Discussion:
The Battery Backup System & Traffic Signal Preemption Project contained the two separate CIP projects: Battery Backup System Upgrade (CP0226) and Traffic Signal Preemption Installation Project (CP9531). These projects are the continuation of the existing projects to retrofit all of the City’s traffic signals with both battery backup systems and emergency vehicle preemption devices. All new traffic signal construction and modification projects include BBS and EVP as standard equipment. These two projects were bundled together for cost efficiency as the two projects are similar in the nature of work and overlapping project locations.
The scope of the Battery Backup System (BBS) project was to install a BBS at existing signalized intersections to provide temporary electrical power to the traffic signal during a power outage. The City converted all traffic signals to LED indicators in 2011 which reduced the power consumption for signal operations and made having a BBS feasible to provide temporary electrical power. The BBS will allow a traffic signal to operate in full mode until the battery is drawn down to a predetermined charge level at which point the signal will turn in “red” flash (approx. 6 - 8hours). This is meant to extend the battery life while maintaining minimal level of traffic control until power has been restored and/or to allow City staff time to place stop signs at the intersection in anticipation of a longer than expected power outage. The goal of this, now biennial project, is to retrofit all existing traffic signals to increase traffic safety during a power outage. The intersections are selected in order of the highest traffic volume to the lowest; to have the greatest impact over time.
There are 48 remaining Traffic Signals in the City without BBS. This project installed a total of fifteen (15) BBS devices leaving a balance of 33 signals to still retrofit. Based on current funding and average number of installations per project the City is on track to have all remaining traffic signals equip with BBS within the next seven (7) years (based on biennial funding).
The Fire Department budgets money in the CIP to install preemption equipment at intersections to systematically install preemption equipment at each City owned traffic signal. The intersections were chosen based on fire department established priority and traffic volumes.
The EVP equipment at the traffic signals will allow Fire Department vehicles to use their preexisting on-board equipment to receive priority at signalized intersections. Priority signalization issues an all-red indication (red ball) to all approaching legs of the intersection except the roadway from which the Fire Department vehicle is approaching from. They receive a green ball allowing the vehicle to continue through the intersection. Consequently, emergency personnel will be able to respond to emergencies both safer and faster.
There are 45 existing traffic signals in the City without EVP system. This project installed a total of four (4) EVP systems leaving a remaining 41 to still retrofit. Based on current and average number of installations per project the City is on track to have all remaining traffic signals equip with EVP within the next eighteen (18) years.
Construction:
The start of construction began on March 7th, 2022; work began with the EVP installations. Following the EVP installations, the project was suspended pending delivery of the BBS hardware. The BBS equipment was delivered in early February of 2023 and the work for the BBS installation was completed in three (3) weeks. The project as a whole was completed in March of 2023. The installation of the BBS and EVP and other associated improvements were completed within the allotted construction working days.
The final total construction cost was $123,500 for BBS work and $81,254 for EVP improvements for a total of $204,754. The construction contract was awarded to Pelagic Engineering out of Oxnard, CA. The original total and final contract amount was $204,754 the project had no construction change orders.
Fiscal Impact:
Battery Backup System & Traffic Signal Preemption Project (3010-72000/CP0226-999 & 3010-72000/CP9531-999) contains two separate projects with different funding sources bundled together for cost efficiencies:
1. Battery Backup System Project (3010-72000/CP0226-999)
a. Gas Tax (Fund 111)
b. Measure R Local (Fund 131)
The BBS project included the completion of the Base Bid and Alternate Bid Items 1-6 as shown in the attached map.
2. Traffic Signal Preemption Project (3010-72000/CP9531-999)
a. General Fund (Fund 001)
b. Fire Impact Fee (Fund 106)
The EVP project include the completion of the Base Bid and Alternate Bid Items 1, 2, 3, and 4 also per the attached map.
