CEQA/NEPA Compliance:
• Three Hills Mine, Tonopah, NV: WJVA Prepared an acoustical analysis for a proposed open mine blasting pit and waste rock disposal area on public lands. Worked closely with the BLM to demonstrate NEPA compliance.
• Kaweah Delta Hospital Helistop, Visalia, CA: WJVA Prepared an environmental noise assessment (ENA) for a new Hospital Helipad to be located near existing residential land uses. Utilized the FAA Integrated Noise Model (INM) to model helicopter noise exposure at nearby existing residential land uses.
• South H Street/Hosking Avenue Commercial Development, Bakersfield: WJVA Prepared and ENA for a proposed large-scale commercial development to demonstrate project compliance with CEQA and local noise standards.
• Culver Mine Project, Tulare County: WJVA Prepared an ENA for a proposed surface mining operation near the City of Porterville. Utlized the SoundPLAN noise model to determine project-related noise levels at nearby residential land uses. Demonstrated project compliance with CEQA and applicable Tulare County noise standards.
• Kern County, CA EIR Revisions to the Kern County Zoning Ordinance, Oil and Gas Local Permitting: WJVA Prepared an ENA for a project level EIR for Oil and Gas operations within Kern County. Responded to County and public comments.
Noise Control Engineering:
• Home Depot Fuel Cells: WJVA has conducted numerous noise studies for proposed fuel cells at several Home Depot stores throughout California. The noise study was used to demonstrate project compliance with local noise standards.
• Car Wash Noise Levels: WJVA has conducted numerous noise studies for proposed car wash operations throughout California. The noise study was required to demonstrate project compliance with local standards and to develop suitable mitigation measures required to achieve compliance.
Roadway Improvement Projects:
• Academy Avenue Roadway Widening, Sanger, CA: WJVA prepared a Noise Study Report (NSR) fulfilling Caltrans requirements for the project. WJVA utilized the FHWA Traffic Noise Model (TNM) and the Caltrans ‘Protocol’ to demonstrate project compliance with Caltrans requirements. The NSR was approved by Caltrans.
• Shepherd Avenue and Fowler Avenue Traffic Signal, Clovis, CA: WJVA prepared a Noise Study Report (NSR) and Noise Abatement Decision Report (NADR) fulfilling Caltrans requirements for the project. WJVA utilized the FHWA Traffic Noise Model (TNM) and the Caltrans ‘Protocol’ to demonstrate project compliance with Caltrans requirements. The NSR and the NADR were approved by Caltrans.
• Southeast Connector, Reno, NV: WJVA prepared a Traffic Impact Study (TIS) for a proposed 6-lane arterial roadway project in Reno. The used the FHWA TNM to demonstrate project compliance and develop mitigation measures required to satisfy NEPA.
Mitigation Monitoring:
• Coolwater Lugo Transmission Lines: WJVA monitoring noise levels near existing transmission lines as well as ambient noise levels along proposed transmission line alignments.
Aviation Noise:
• McCarran International Airport, Las Vegas, NV: WJVA prepared an Aircraft Noise Monitoring Report for the airport. The report presented sound level data obtained over a two-week period using automated sound level meters at monitoring sites throughout the City of Las Vegas.
• Livermore Municipal Airport: WJVA prepared an Aircraft Monitoring Report for Livermore Municipal Airport. Noise monitoring occurred over two individual two-week periods to demonstrate changes in aircraft noise exposure throughout the Spring and Fall months.
• Watsonville Municipal Airport: WJVA prepared an Aircraft Noise Assessment for Watsonville Municipal Airport. The Aircraft Noise Assessment included week-long noise monitoring at five locations utilizing automated sound level meters in addition to the development of aircraft noise exposure contours utilizing the INM.
• Reno Tahoe International Airport: WJVA was the acoustical consultant for the Airport Sound Insulation Project. WJVA utilized proprietary software to quantify interior aircraft noise levels within residential buildings. Interior noise levels were obtained both before and after acoustical treatments were provided to the homeowners, to demonstrate improvement as well as compliance with FAA project requirements.
• Ted Stevens International Airport, Anchorage, AK: WJVA was the acoustical consultant for Residential Sound Insulation Project. WJVA utilized artificial noise sources, in compliance with FAA guidelines and ASTM standards, to demonstrate interior noise level improvements and compliance with FAA project requirements.
