lighting; street and parking area lighting; interior lighting for commercial, retail stores/restaurants and residential uses; as well as increased vehicle headlights due to the intensified uses in the Overlay Zone. It should be noted that no high -intensity lighting (e.g., sports field lighting) is currently anticipated within the Overlay Zone. Although the St. Jeanne De Lestonnac School has a sports field, this land use is not located within the Overlay Zone. Due to the urbanized nature of the surrounding area, a significant amount of ambient nighttime light currently exists, reducing the views of stars and affecting views of the nighttime sky. Thus, the increase in nighttime light that would occur under the Overlay Zone would not significantly affect nighttime views of the sky (ability to see stars) because such views are already limited in city settings. Therefore, the impact related to ambient nighttime light was determined to be less than significant. Spillover Light New development in the Overlay Zone would introduce new and potentially substantial sources of nighttime lighting. Lighting would be used to highlight architectural elements, landscaping, and building tenant and project signage. In addition, security and safety lighting would be provided in parking areas, service passages, and common areas utilized by employees and visitors during and after commercial operating hours. Further, because minimal nighttime traffic is present in the Overlay Zone, increased vehicular traffic could result in more opportunities for vehicular headlights to affect surrounding residences. The increase in the Overlay Zone lighting could potentially affect adjacent uses if new buildings were developed next to existing sensitive uses (i.e., residential uses) that do not experience impacts from existing lighting sources or if tall buildings included significant neon lighting or lighted signs. The nearest residential neighborhood is located immediately adjacent to the northern boundary of the Overlay Zone. As discussed above in Impact 4.1-1, the Neighborhood Transitional District would frame the northern boundary of the Overlay Zone area, and the scale and design of buildings in this area would reflect the relationship to the adjacent residential uses. Building heights would range between two- and three- stories, and development in this area would be specifically designed to provide an appropriate interface with high levels of landscaping and design features to minimize impacts to the adjacent residential area to the north. The Overlay Zone would provide outdoor lighting standards that aim to prevent impacts on surrounding residential uses. Although the Overlay Zone would provide outdoor light standards, future development could create light pollution disturbances which do not exist. Depending on the location and design specifications of lighting on future buildings, lighting could present a potentially significant Implementation of Mitigation Measures MM-OZ 4.1-2 and MM-OZ 4.1-3 will ensure these lighting impacts will be less than significant. Shade/Shadow The current low-rise buildings within the Overlay Zone create limited shade and shadow patterns that are contained within close proximity to each low- to mid -rise building. In the Overlay Zone Active Urban District, shadows cast by existing on -site development are more extensive. Future development of new multi -story buildings in the Overlay Zone may create new sources of shading Cabrillo Town Center City of Santa Ana Technical Memorandum August 2023 City Council 18 — 494 10/3/2023
