Series Street Light Replacement
Project Summary

The City owns and operates approximately 40 street lights that are powered by high voltage series circuits. These lights are more difficult to troubleshoot and repair than standard lights and are at the end of their useful life. This project includes reviewing the Town’s street lights to specifically identify which lights are powered by series circuits, designing new circuitry and replacing the high voltage lights with current standard parallel circuit lights.

The new lights will be energy efficient, safer and more reliable. This project will also analyze and make recommendations on issues such as upgrading the rest of the Town's approximately 210 lights to energy efficient lights, purchasing the approximately 185 PG&E owned distribution lights located in Town and seeking an alternate maintenance provider.

Current Status

The Town entered awarded a agreement with W-Trans in March of 2015 to provide design plans, specifications and estimates (PS&E) to replace the Town's series circuits and to provide the related engineering services. W-Trans has performed preliminary engineering on the project including tasks such as performing an inspection of the Town's street lights, determining which lights are fed by series circuits, and designing new circuitry.

The inspection found that there are four separate series circuits in Atherton that power a total of 35 lights. The existing street light poles will continue to be used at the same locations. The underground conduits, wires and the light fixtures will be replaced with new parts. The project is expected to clean and re-paint the poles. 

Staff is aiming to start construction of the replacement lighting systems in the Spring of 2016.

The Consultant is continuing to look at items such as upgrading the rest of the City's lights to Light Emitting Diode (LED) technology, and future ownership and maintenance options. The team is seeking to install sample LED fixtures that the community can view and provide feedback in the coming winter. Additional information regarding the location of the sample LED fixtures will be provided in coming weeks.
