Chapter 5 Statement of Overriding Considerations single, non-renewable resource base and considers the additive effect of project- specific impacts to significant regional impacts on cultural resources. Because all cultural resources are unique and non-renewable members of finite classes, all adverse effects or negative impacts erode a dwindling resource base. Federal, state, and local laws protect cultural resources in most instances. Even so, it is not always feasible to protect cultural resources, particularly when preservation in place would frustrate implementation of projects. For this reason, the cumulative effects of development in the Orange County region are considered significant. However, because it is currently infeasible to determine whether future development under the proposed Transit Zoning Code would result in demolition or removal of historical resources within the project boundaries, the project's incremental contribution to these cumulative effects would be cumulatively considerable (i.e., the project would contribute to the loss of historical resources in Orange County). Noise Impact 4.8-8 Operation of the Southern California Regional Rail Authority's (SCRRA) rail line would potentially expose noise-sensitive land uses located within the Transit Zoning Code (SD 84) area to noise levels that exceed the standards established by the City of Santa Ana General Plan. Impact 4.8-9 Construction activities associated with the proposed project would generate or expose persons or structures to excessive ground borne vibration. Cumulative Construction of individual projects pursuant to the Transit Zoning Code would produce temporary vibration impacts. As discussed in Impact 4.8-9, the construction vibration impact would be significant and unavoidable. As individual development projects under the Transit Zoning Code (SD 84) area may be constructed concurrently with each other or other related projects, it is possible that intense construction from two or more projects would simultaneously occur at distances of 50 feet or less from existing nearby receptors. Therefore, vibration from future development would potentially combine with construction vibration of other projects to result in a potentially significant cumulative impact. Cumulative The proposed project is located within close proximity to the Southern California Regional Rail Authority's (SCRRA) rail line. Sensitive receptors, including residential uses with exterior uses such as communal areas consisting of pocket parks or pedestrian walkways and private balconies, may or may not be shielded from noise generated by railroad operations. As a result, noise levels within these areas may exceed the 65 dBA CNEL "Desirable Maximum" standard. Transportation Impact 4.11-9 Long-term cumulative development under implementation of the Transit Zoning Code would result in impacts related to freeway ramps in the vicinity of the Transit Zoning Code area. Cumulative As identified in Impact 4.11-8, because implementation of the proposed project would contribute to significant impacts at the study area intersections, and Transit Zoning Code (SD 84) EIR Findings of Fact/Statement of Overriding Considerations 5-7
