City of Pleasanton—Additional Housing Sites Rezonings Project CEQA Guidelines Section 15164 Addendum Addendum 33 d) Light and Glare Would the project: Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? Summary of Prior FEIR According to the Prior FEIR, new development within the City would introduce artificial light from new commercial and residential development, as well as outdoor parking areas and street lighting. Although buildings within the City could include exterior building materials that could reflect sunlight, creating glare for nearby residents and motorists, the Prior FEIR stated that individual development applications would be subject to design review, which would ensure that such impacts would be avoided. Furthermore, all new development within the City would be subject to the State’s Nighttime Sky-Title 24 Outdoor Lighting Standards, which would limit the amount of outdoor light associated with new development within the City, thus minimizing nighttime illumination impacts. Additionally, the Prior FEIR stated that relevant provisions of the City’s Municipal Code would serve to limit glare and spillover light from signs, as well as limit interior and exterior illumination. Development within the City is also required to be consistent with the California Building Code (CBC) standards for outdoor lighting, which are intended to reduce light pollution and glare by regulating light power and brightness, shielding, and sensor controls. Overall, the Prior FEIR concluded that adherence to the aforementioned standards and guidelines would ensure that impacts related to light and glare would be less than significant. Proposed Project Analysis and Conclusion The proposed sites are in the same urban setting as those evaluated in the Prior FEIR. Development consistent with the proposed project could introduce artificial light from new development and outdoor parking areas. Examples of light and glare include streetlights, freestanding lights, building-mounted lights, reflective building materials, and vehicular headlights. Currently, the proposed sites contain lighting sources associated with existing buildings and related parking lots. Developed portions of the areas surrounding the proposed sites also contain numerous existing sources of light and glare, including streetlamps and exterior residential lights. While it is too speculative at this time to determine what potential light sources may be part of new developments, future development would be required to comply with the applicable light and glare standards in the Municipal Code, including those stated in Section 18.20.030, which requires that design review evaluate the relationship of exterior lighting to its surroundings and to the
