Learn why this is important <br />October 14, 2024 <br />Dear Mayor Gee and Council Members: <br />We submit the following comments with regard to Item 8.A on the October 14 Council agenda <br />regarding “Consideration of a phased approach to allowing digital billboards in Redwood City, <br />with phase one allowing one digital billboard in Redwood City”. <br />Digital billboards have the potential to negatively impact wildlife and people due to the effects of <br />light pollution. Therefore, digital billboards should not be allowed in any areas near to sensitive <br />wildlife habitat or residences and also impact driver safety. <br />The staff report states that Caltrans regulations prohibit digital billboards along a “landscaped <br />freeway” or within 500 feet of another billboard. The staff report further states that within the <br />Highway 101 corridor in Redwood City, only approximately 0.2 miles does not qualify as <br />“landscaped freeway” segments. From the map entitled “Map 1A” in the staff report, it appears as <br />though this 0.2 miles consists of two areas, one located where 101 crosses over Redwood Creek, <br />and one located slightly north of the Woodside Road interchange with 101. <br />The staff report also mentions the possibility of removing existing static billboards in exchange for <br />allowing new digital billboards in the same location. As shown in Maps 1 and 1.A, those existing <br />static billboards are located on the east side of 101, directly adjacent to the Bair Island Ecological <br />Reserve. <br />Environmental impacts of digital billboards <br />According to Dark Sky International, electronic billboards can be up to ten times brighter at night <br />than traditionally lit billboards. Because there is no way to shield or direct the light that digital <br />billboards emit, this nighttime lighting inevitably spills into adjacent areas. Any digital billboards <br />located along Highway 101 adjacent to either Redwood Creek or the Bair Island Ecological <br />Reserve would increase the amount of light that shines into these wetland and riparian areas, <br />which are critically important for local wildlife. Bair Island, in particular, is part of the Don Edwards <br />Wildlife Refuge, a federally-owned nature preserve that provides habitat for many sensitive <br />species, including threatened and endangered species like the Ridgway’s Rail and the salt marsh <br />harvest mouse. <br />Exposure to artificial light at night can have physiological impacts on wildlife. It can disrupt <br />animals’ circadian rhythms, cause alterations in hormone cycles, and impair the vision of <br />nocturnal animals. <br />There is unequivocal scientific evidence to establish the significant and unavoidable harm that Artificial
