• AM/PM Minimart, 99th Street & Hazeldell Operations Noise Impact, Vancouver, Washington

As part of a proposed land use rezoning permit from residential to light commercial/retail, SFMI measured the existing 24 hour Ldn noise levels at the site and compared them with maximum noise levels contained national standards recommended. The existing and future sound levels were found to greatly exceed the recommended limits, supporting the rezone.

Measurements were similarly made of existing uses similar to that proposed. Noise emissions from similar existing uses were found to be lower than the ambient noise already on the site.

• Exxon Station, Gas Station and Car Wash Operations Noise Impact , Mountain View, California

To allow the station to implement automated car wash equipment, SFMI first compared the noise levels at the proposed site with the noise levels of a site where the equipment was already in operation.

Furthermore, SFMI prepared mitigation measures to allow the facility to comply with code and to receive permit for its change of use. The measurements included:

• 12 hours peak weekday and minimum weekend property line ambient
• level versus time
• peak spectrum

Client: Majors Engineering, San Ramon, California

• Exxon Station, Gas Station and Car Wash Operations Noise Impact, Pleasanton, California

Measured equipment comparable to that proposed for use in the Pleasanton facility and provided recommendations for mitigation to City of Pleasanton standards.
