Using general capital project funds of $118,820, the city council of Sausalito, California, has authorized the department of public works to begin planning and implementing the city’s first major LED streetlight installation. City officials determined that using capital funds would help the city realize immediate savings from energy use reduction. According to the department of public works, the city will replace approximately 276 existing high pressure sodium (HPS) and mercury vapor streetlights with LED streetlight fixtures manufactured by Leotek Electronics of Milpitas, California. In addition to the HPS and mercury vapor streetlights, the city also owns about 190 incandescent streetlights which are also targeted for future replacement.
“We are modeling our project on the one recently completed in Novato, California. The city will ‘piggyback’ on the existing Novato contract with Republic ITS for the purchase and installation of the LED streetlight fixtures,” said Jonathan Goldman, public works director for the city of Sausalito. The Sausalito city charter allows for a provision of cooperative purchasing which permits the city to purchase and install a commodity through a sole source contract. The cooperative purchase of LED streetlights was reviewed by both legal counsel and the city council and determined to be the best and most efficient use of the capital funds. In addition to the project fund, a small contingency fund was allocated for unexpected repairs and replacements which are discovered during the project installation phase.
Although this project will be the city’s first larger scale installation, several LED fixtures have already been installed and evaluated by the city’s public works department. These fixtures were installed when existing HPS or mercury vapor fixtures failed or were damaged. Calculations show that the 276 new LED streetlights will save the city about $14,000 annually in energy costs alone. Additional savings may also be realized from reduced maintenance requirements. Greenhouse gas emissions are expected to be reduced by about 71,410 pounds per year. The city plans to begin the project in approximately two months.
