Analysis Supporting Categorical Exemption species.The entire Project Site is characterized as developed with some landscaped land cover in the form of ornamental trees and landscaped plants along the sidewalks of Fairview Street. Within a 100-foot buffer, similar development and landscaping are present. No records of special-status species located within the Project Site were identified during the literature review. Due to the developed nature of the Project Site, special-status plant and wildlife species identified in the literature review were presumed absent from the Project Site. The Project Site is not considered, nor is it a part of, a wildlife movement corridor or linkage. Some tree removal and trimming are planned as part of the Project. ECORP recommends seasonal avoidance oftree trimming/removal activities during the nesting bird season(typically February 1 through August 31) and the bat maternity season (typically April 1 through August 31) to the maximum extent practicable;and implementation of similar, but species-specific, preconstruction surveys and avoidance measures(as deemed appropriate by a qualified biologist), if tree trimming or removal activities cannot feasibly avoid bat maternity season and the nesting bird season in compliance with the Migratory Bird Treaty Act. Therefore, the Project would have a less than significant impact. 4.5 Cultural Resources 4.5.1 Records Search ECORP conducted a recordssearch of the Project Area at the California Historical Resources Information System(CHRIS)South Central Coastal Information Center (SCCIC) located at California State University- Fullerton on November 14, 2024 (Appendix Q. The purpose of the records search was to determine the extent of previous surveys within a 0.5-mile(800-meter)radius of the Project Area,and whether previously documented pre-contact or historic archaeological sites, architectural resources, or traditional cultural properties exist within this area. In addition to the official records and maps for archaeological sites and surveys in Orange County, the following historic references were also reviewed:Built Environment Resource Directory (BERD) for Orange County(OHP 2024a);the National Register Information System(National Park Service [NPS] 2024); Office of Historic Preservation (OHP), California Historical Landmarks (OHP 2024b) and California Historical Resources (OHP 2024c). 4.5.2 Previous Research Fifteen previous cultural resource investigations have been conducted in or within 0.5 mile of the Project Area,covering approximately sixty percent of the total area within the records search radius (Table 5). Of these 15 studies,three included a portion of the Project Area. The remaining 12 studies were conducted within the 0.5-mile search radius. The previous studies were conducted between 1975 and 2010.
