level through compliance with federal, state and local use, storage and transport regulations and the mitigation mcasures proposed in the Drah EIR. The Concurrcnt Extension therefore will not pose any new significant hazards or hazardous marerials impacts or substantially increase the severity of such impacts beyond what is idemified in the Draft EIR. 3.5 I-lydrology and Water Quality Impacts on hydrology and water quality will remain substamially the same with the Concurrent Extension because the Concurrent F.xrension will not alter the proposed uses of the project site. The Concurrent Extension of an additional two lanes of Stoneridge Drive may introduce limited additional impervious area at an earlier date than the Deferred Extension. The Concurrent Extension would also require the construction of a second bridge across Arroyo Mocho earlier than otherwise anticipated. (See, Section 3.3 above for related mitigation). However, the aggregate impacts of the Concurrent Extension and the Deferred Extension are the same. Compliance with the same BMPs, local, state and federal permitting requirements, and mitigation measures discussed in the Draft E.IR will reduce any potential additional impacts of the Concurrent Extension to a less than significant level. Biological Resources The Concurrent Extension therefore will not pose any new significant hydrology or water quality impacts or substantially increase the severity of such impacts beyond what is identified in the Draft F.IR. 3.6 Land Use and Agricultural Resources "I'he analysis of the Draft EIR comprehends the impacts of the Concurrent Extension because the proposed uses of the Staples Ranch site arc [he same under the Concurrent Extension and the Deferred Extension. The Concurrent Extension therefore will not pose any new significant land use or agricultural resources impacts or substantially increase the severity of such impacts beyond what is identified in the Draft EIR. 3.7 Noise The impacts of constructing an additional two lanes of Stoneridge Drive and pile- driving associated with the construction of a second bridge across Arroyo Mocho will be the same as the impacts analyzed by the Draft EIR for the first two lanes and first bridge of Stoneridge Drive. The combined noise impacts of conremporaneous construction of both halves of Stoneridge Drive with the Concurrent Extension will not be greater than with the Deferred Exrension because the noise created by the construction of each halfofSroneridge Drive will be reduced to a less than significant level by the noise attenuation measures of Mitigation Measure NO-3.1. .Additional pile- driving noise impacts associated with the construction of a second bridge across Arroyo Mochn would also be mitigated to a less than significant level by Mitigation Measure NO-2.1 because it requires compliance with the same peak particle velocity standard regardless of whether one or two bridges are constructed at any given time. The same notification requirements of Mitigation measure NO-2.2 would alsu apply to reduce pile-driving impacts to a less than significant Level.
