Johns Creek Environmental Campus
Brown & Caldwell - Roswell, GA
This 30-MGD design/build wastewater treatment plant was constructed on a 43-acre lot adjacent to residential properties between 2006 and 2009. Greenbusch constructed a 3-dimensional computer noise model of the facility and surrounding environments to develop mitiation recommendations. A post-audit was performed during a full-capacity fresh water test, verifying achievement of the owner's requirements.
City of Seattle Fleet Maintenance Facilities
KPG - Seattle, WA
Greenbusch provided the acoustical design for renovations of Haller Lake and 805 Charles Street maintenance facilities. The company conducted noise measurements to assess the existing conditions and provided recommendations for interior finishes to reduce the existing noise levels.
Port Angeles Mill Environmental Study
Interfor Pacific Port Ang. Mill - Port Angeles, WA
Greenbusch evaluated noise levels associated with operations at this Port Angeles Mill to predict expected noise levels associated with a proposed expansion of the mill. The company also created a sound noise abatement program to ensure that noise levels along the property lines complied with pertinent noise criteria.
Soil Remediation System Noise Study
Cornerstone Environmental/SAIC - San Bruno, CA
Sound levels generated by a soil remediation system at a site formerly occupied by a gasoline station were a source of community complaint. Greenbusch completed a detailed assessment of City Noise Code compliance at neighboring residential properties and individual equipment contributions to the total sound emission.
