Project: 820190 - Traffic Signal Hardware and Wiring
Project Description/Scope/Purpose:
This project provides funding for design and construction for replacement of traffic signal underground conduits and signal pole structures at the end of their estimated life span. Underground cables and conduits have a life expectancy of approximately 35 years. Signals identified for replacement are evaluated by location specific assessments based upon an inventory of traffic signal life cycles. The City has 136 traffic signals. Out of these, 72 are beyond their design life and are due for replacement.
The traffic signal at Sunnyvale/Hendy was designed in FY 2018/19 and will be constructed in FY 2020/21.
For future projects, design and construction for two traffic signals will be performed in alternating years. Fair Oaks/California, and Bernardo/Heatherstone will be designed in FY 2021/22 and constructed in FY 2022/23.
Fiscal Impact:
This project is funded by the Gas Tax Fund. The budget provided is sufficient for two signals per two-year cycle. Project costs are based on bid history and construction prices received. Near term funding levels are calibrated to match conditions in the field.
Project Type: Traffic and Transportation
Year Identified: 1999
Est. Completion Year: Ongoing
Underground conduits/substructures, as they age and corrode, become filled with dirt and water as they age and corrode and cannot be cleaned. Failure to replace systems may result in wire failure in the future with no means of quick replacement and signal shutdown for multiple days until replaced. Traffic signal poles and associated hardware are evaluated for replacement concurrently in order to consider updated design standards and condition of infrastructure.
Project costs are based on bid history and construction prices received.
