Impact 5.3-4: Implementation of the General Plan Update could result in adverse impacts to candidate, sensitive, or special -status species. The City of Santa Ana is largely urbanized, and migration corridors are generally limited to the Santa Ana River and the Santiago Creek. Development under the GPU would result in the further infill of the city and removal of vacant sites. The GPU would not change land use designations of parcels that encompass the Santa Ana River or the Santiago Creek. However, development under the GPU could further result in vegetation removal, intrusion by humans and pets, and increased noise and air pollutants, which could impact wildlife movement and nesting sites. Therefore, the buildout of the GPU could affect wildlife movement, nesting sites, and migratory birds protected under the Migratory Bird Treaty Act as well as state law. Impact 5.3-4 would be less than significant with compliance with all applicable federal, state, and local regulations and incorporation of mitigation measure BIO-1. Mitigation Measures Refer to BIO-1 above. Finding Finding 1. The City hereby makes Finding 1. Changes or alterations have been required in, or incorporated into, the project that avoid or substantially lessen the significant environmental effect as identified in the PEIR. These changes are identified in the form of the mitigation measure above. The City of Santa Ana hereby finds that implementation of the mitigation measure is feasible, and the measure is therefore adopted. 3. Cultural Resources Impact 5.4-2: Development in accordance with the General Plan Update could impact archaeological resources. Development involving ground disturbance within the plan area has the potential to impact known and unknown archaeological resources. Typically, surface -level and subsurface archaeological sites and deposits can be affected by ground -disturbing activities associated with most types of construction. Based on literature review and records searches, eight archaeological resources have been recorded within the plan area, including four prehistoric sites, one multicomponent site, and three historic isolates. The plan area includes many locations that would have been favorable for prehistoric Native American occupation. While most of the plan area has been developed over the course of the twentieth century, buried resources may remain in areas where developments such as parking lots, parks, or structures with shallow foundations have required only minimal ground disturbance. A review of historical and ethnographic maps indicates a moderate likelihood that intact subsurface archaeological resources would be encountered during redevelopment. Archaeological resources impacts are site specific, but more intensive development can result in cumulative impacts on a regional level and should be considered in addition to individual project Santa Ana General Plan Update CEQA Findings of Fact and Statement Of Overriding Considerations -29- October 2021
