HARBOR BLVD. MIXED USE TRANSIT CORRIDOR PLAN FINAL FIR CITY OF SANTA ANA 5. Environmental Analysis CULTURAL RESOURCES C -1 Cause a substantial adverse change in the significance of an historical resource pursuant to Section 15064.5. C -2 Cause a substantial adverse change in the significance of an archaeological resource pursuant to Section 15064.5. C -3 Directly or indirectly destroy a unique paleontological resource or site or unique geologic feature. CA Disturb any human remains, including those interred outside of formal cemeteries. The Initial Study, included as Appendix A, substantiates that impacts associated with the following thresholds would be less than significant: C -1 and C -4. These impacts will not be addressed in the following analysis. 5.3.3 Environmental Impacts The following impact analysis addresses thresholds of significance for which the Initial Study disclosed potentially significant impacts. The applicable thresholds are identified in brackets after the impact statement. Impact 5.3 -1: Future development that would be accommodated by the Harbor Boulevard Mixed Use Transit Corridor Plan could impact unknown archeological and/or paleontological resources. [Threshold C -2 and C -31 Impact Analysis: The project area is in a highly urbanized, built -out portion of the City and is developed with a mix of commercial and residential uses. The project area also contains the Willowick Golf Course (an operating 18 -hole public golf course), Cesar Chavez /Campesmo Park, and Santa Anita Park. Existing uses are shown in Figure 3 -3, Aerial Photograph. Land uses surrounding the project area include a mix of residential uses, which vary widely in character and density and include single - family neighborhoods, apartment complexes, and mobile home communities. Long -term implementation of the Harbor Boulevard Mixed Use Transit Corridor Plan would allow development (e.g., infill development, redevelopment, revitalization /restoration, and roadway improvements) within the project area, including grading, of unknown sensitive areas. Following is a discussion of potential impacts on archeological and paleontological resources as a result of project implementation. Archeological Resources Archeological resources are the physical remains and traces of past human activity such as artifacts, residues, and built features. No archaeological sites or isolates, either historic or prehistoric, have been identified onsite or within 0.5 mile of the project area (SCCIC). Additionally, the project area has no inherent cultural significance. Furthermore, the majority of the project area is in a highly urbanized, built out portion of the City and has been heavily disturbed over the years. Since the majority of the project area has been previously disturbed by grading and construction, it is unlikely that any subsurface archaeological resources currently exist that could be impacted by ground disturbing activities of future development projects accommodated by the Harbor Boulevard Mixed Use Transit Corridor Plan.
