San Rafael, CA –
Phase 1 of project to revise street lighting will focus on foundation work
Work will begin the first week of August to revise street lighting on the median islands along one mile of Sir Francis Drake Boulevard, between Manor Road in Kentfield and Eliseo Drive in Greenbrae.
Overseen by the Marin County Department of Public Works (DPW), the lighting update project will address street lighting that was installed during the Upgrade the Drake project, completed in November 2021, replacing a selection of lighting poles with shorter, decorative poles, and dimmer fixtures.
The work starting next week will be the first phase of the project and will focus on structural foundations and wiring connections. This phase is expected to take about one month to complete, finishing in time to avoid the influx in traffic expected when the school year starts in late August.
Traffic impacts are expected to be minimal. A 500-foot stretch of one eastbound lane on Drake Boulevard will be closed for the duration of Phase 1. Traffic is expected to flow normally through the other two lanes. However, during the first week of August, there will be an additional lane closure of a westbound lane for two days to ensure crew safety during some initial work on several poles. The lane closures may cause traffic delays during peak commute hours.
The second phase is expected to begin sometime in the fall. A selection of existing street light poles will be removed and replaced with shorter, decorative light poles. In April 2022, the Marin County Board of Supervisors approved the purchase of the new light poles, costing an estimated $300,000. The poles require significant manufacturing lead time, taking approximately six months to be fabricated and delivered. DPW expects the new poles to be available in October.
In response to community concerns regarding lighting enhancements implemented during the Upgrade the Drake project, the street lighting project is intended to reduce light dispersal on adjacent properties, decrease light intensity, and improve aesthetics while still maintaining the lighting uniformity levels necessary for public safety. The shorter, decorative poles with dimmer fixtures will require closer spacing to achieve sufficient light levels on the roadway, resulting in a net increase in total lights. Statistically, uniform nighttime street lighting improves safety for all modes of transportation.
In January 2022, DPW replaced lighting fixtures at intersections and added backshields to help block light dispersal outside of the roadway and sidewalks. In June, the County replaced all remaining light fixtures on existing poles throughout the 2.2-mile corridor from the Town of Ross to Highway 101, as well as adding more backshields where necessary. The dimmer fixtures have a brightness of 5,000 to 8,000 lumens, depending on the needs of each location. For comparison, the removed fixtures had a brightness of 12,000 lumens.
The street light revisions are being funded by the remaining budget of the Upgrade the Drake project and the Marin County Street Light Fund. To further offset the cost, DPW will explore resell opportunities for the currently installed street light poles, which are a standard pole design used across California.
