Chapter 4 Statement of Overriding Conslderatlons <br />state, and local laws protect cultural resources in most instances. E~=en so, it is not <br />always feasible to protect cultural resources, puticularly when preservation in <br />place ~~>ould frustrate implementation of projects. For tits reason, the cumulative <br />effects of dew>elopment in [he Orange Count}• region are considered significant. <br />However, because it is currently infeasible to determine whether future <br />development under the proposed Transit Zoning Code would result in demolition <br />or remo~•al of historical resources within the project boundaries, the project's <br />incremental contribution to these cumulative effects u>ould be cumulatively <br />considerable (i.e., the project would contribute to the loss of historical resources <br />in Orange Count}•)• <br />Noise <br />Impact 4.8-8 Operation of the Southern California Regional Rail Authority's (SC12RA) rail line <br />would potentially expose noise-sensitive land uses located «•ithin the Transit <br />Zoning Code (SD 84) area to noise le~•els that exceed the standards established by <br />the City of Santa Ana General Plan. <br />Impact 4.8-9 Construction activities associated with the proposed project would generate or <br />expose persons or structures to excessive ground borne vibration. <br />Cumulati~•c Construction of individual projects pursuant to the 'transit Zoning Code would <br /> produce temporary vibration impacts. As discussed in Impact 4.8-9, the <br /> construction vibration impact would be sigtficant and unavoidable. As indi~•idual <br /> development projects under the Transit Zoning Code (SD 84) area Ina}• be <br /> constructed concurrently with each other or other related projects, it is possible <br /> that intense construction from to>o or more projects would simultaneousl}' occur <br /> at distances of SO feet or less from existing nearby receptors. Therefore, vibration <br /> From future deg*elopment would potentially combine «rith construction vibration <br /> of other projects to result in a potentially significant cumulative impact. <br />Cumulative The proposed project is located within close proximity to the Southern California <br /> Regional Rail Authorit}•'s (SCI2I2_A) rail lint. Sensiti~*e receptors, including <br /> residential uses with exterior uses such as communal areas consisting of pocket <br /> parks or pedestrian walkways and private balconies, may or may not be shielded <br /> from noise generated b}• railroad operations. As a result, noise levels witlisi these <br /> areas map exceed the G5 dBA CNEL "Desirable I~•iaaimuni" standard. <br />Transportation <br />Impact 4.11-9 Long-term cumulative development under implementation of die Transit Zoning <br /> Code would result in impacts related to Freewa}• ramps in the vicinity of the <br /> Transit Zoning Code area. <br />Cumulative As identified in Impact 4.11-8, because implementation of the proposed project <br /> would contribute to sigtvficant impacts at the study area intersections, and <br /> because implementation of the potential improvement measures cannot be <br /> guaranteed, the long-term cumulati~-e de~relopment pursuant to the Transit <br /> Zoning Code would have a considerable contribution t~•~t~~t~~024 <br /> Page 89 of 130 <br />Transit Zoning Coda (SD 84) EIR Findings of Fact/Stetement of Ovarrld(ng Conslderattons 4-3 <br />
