RGD has restarted the sound and vibration monitoring at the Marysville Ring Levee for the 2012 construction season.  The US Army Corps of Engineers is sponsoring a levee strengthening project in the Yuba River Basin to protect the residential area in Marysville, California.  RGD is helping Magnus Pacific and Raito satisfy the Corps’ sound and vibration specification while they conduct deep soil mixing (DSM) improvements.  RGD conducted the continuous sound and vibration during the 2011 construction season and has now restarted the monitoring for the 2012 season.
