Landscaping and Lighting No changes to lighting are proposed; however, due to the provision of surface parking on the site, the amount of landscaping would be reduced from approximately 0.94 acre of landscaping to approximately 0.48 acre of landscaping on the site. The landscaped areas would be located throughout the site and additional street trees would be planted along N. Main Street and Edgewood Road. The residential building would be adjacent to landscaped courtyards. Many of the existing mature trees that line the eastern and southern site boundary would remain; however, trees that are located throughout the remainder of the site, within construction areas, or are in poor or declining health would be removed. New ornamental landscaping would be installed throughout the site that would include a variety of 24- through 48-inch box trees, 1 – 5-gallon shrubs, and ground covers. Additional trees ranging in size from 24- to 48-inch box trees would be added to the eastern property line to fill in gaps in the mature landscaping to screen views between the site and adjacent residential areas. The Project would also install 24- and 36-inch box trees and tree wells along Edgewood Road and N. Main Street and may replace existing street trees. New plant species used in the landscaping would be drought-tolerant, non-invasive, and compliant with the City of Santa Ana’s landscaping requirements. Likewise, the new irrigation installed onsite would meet the City’s requirements for water efficiency (Santa Ana Municipal Code Section 41-1503; Landscape Water Use Standards). As described in the EIR, new exterior lighting onsite would be provided for security and to accent the landscaping, Project signage, light walkways, and parking areas. The new lighting would be focused on the Project site, shield offsite areas, and would be compliant with the City’s lighting regulations (Santa Ana Municipal Code, Section 8-210 and Section 41-611.1). Infrastructure No changes to the proposed infrastructure connections are proposed, and these connections would include the following: • Water Infrastructure: As detailed in the EIR, the Project would install new water infrastructure on site that would connect to the existing 16-inch water pipelines in N. Main Street and Edgewood Road. The new onsite water system would be compliant with the CalGreen Plumbing Code (Title 24) for efficient use of water. • Wastewater Infrastructure: Wastewater from the Project site currently discharges into existing City-owned 6- and 12-inch sewer lines within Edgewood Road. As detailed in the EIR, the Project would install a new onsite sewer system that connects to the existing sewer lines in Edgewood Road. • Drainage Infrastructure: As detailed in the EIR, the existing 10-inch storm water drain that conveys unfiltered runoff to Santiago Creek would be capped and all of the runoff from the site would be conveyed to new infiltrating landscaping areas, catch basins, and storm water drains that would be sized to meet the Project’s needs. The onsite system would connect to the existing City drain system in N. Main Street and Edgewood Road, which discharges to Santiago Creek. Project Design Features A reduction in the number of electric vehicle charging stations are proposed. The Original Project included at least 25 electric vehicle charging stations and the Modified Project includes at least 15 electric vehicle charging stations. No other changes in Project Design Features (PDFs) are proposed. The following PDFs would prevent or lessen environmental impacts and would be implemented in the same manner as mitigation measures: • PDF-1: The landscape plan will incorporate the existing mature trees located along the eastern Project site boundary and to the extent feasible protect and preserve the existing mature trees within the 15-foot setback along the southern boundary within the 15-foot setback along the southern boundary that were identified as healthy by the Arborist Report. • PDF-2: The Project will include at least 15 electric vehicle charging stations. 2-134
