In our last episode, we learned that the 5,000 volt series circuit serving 21 streetlights between Ensign and Litho on Caledonia was red-tagged and locked out by PG&E owing to numerous failures in the 70-year old metallic lead wiring. The City and Siemens (the County-wide streetlight maintenance contractor) have furnished satisfactory temporary lighting to address pedestrian safety issues at night including the late addition of a solar-powered, light-emitting diode (LED) light tower at the southeastern corner of Ensign for the Bridgeway crosswalk at that location. This week, DC Electric (the City’s contractor on this matter), has removed the historically-significant metal fixtures and tear-drop globes to allow us to evaluate whether they can be cleaned, repaired and retrofitted with new LED light sources, or should be replaced. Two similarly-shaped new teardrop fixtures using LED light sources have been installed for evaluation at the north end of Caledonia just south of Napa. These are just two of several new fixtures being considered should repairing and retrofitting the old not prove feasible. Comments on the appearance of the new fixtures as well as the quality of their illumination are welcome.
It is expected that a contract to construct the rewiring project will be let at the June 4, 2013 Council meeting with notice to proceed following immediately thereafter, although the provision of satisfactory temporary lighting allows us to delay that process if improvements to the design are identified during the pre-bid period.
