Noise is one of the “topical issues” studied in the Final Environmental Impact Report (EIR) and Technical Appendices. Noise studies are performed according to established industry protocols with specifications for measurement and interpretation.
Actual noise data was collected specifically for the EIR from operations at the Kelly Slater Wave Company Surf Ranch facility in Lemoore, California. The technology there is similar to what will be used at Coral Mountain but is considered conservative in some respects because advancements in design are planned for Coral Mountain.
The collected Lemoore data was entered into an accredited computer model that considers local site conditions, including landform composition (rock, earth, landscaped, etc.) and topography.
During the Final EIR preparation, updated noise measurements were taken at Lemoore to gauge the results of upgrades and improvements in the equipment used to generate the Wave. Noise levels were reduced due to these improvements, although operational noise levels were already within acceptable levels under the City’s noise criteria.
Noise is mitigated below thresholds of significance per the noise criteria. And notably, there is no reverberation or reflection of noise from the Wave Basin off the Coral Mountain topographic features, per the noise analysis.
Conclusion: Noise generated by the project is below significant levels per the City’s General Plan standards and Municipal Code noise regulations.
