McLaren Engineering Group was enlisted by the New Jersey Department of Transportation (NJDOT) to assist with the Superstorm Sandy recovery effort. As part of the FEMA Category B – Emergency Protectors Measurers team, the firm provided surveying and engineering services to locate debris and shoaling. The NJDOT worked with McLaren to map the condition information for all navigation in state channels and shore areas to protect the public from injury and harm.
McLaren provided bathymetric surveys for approximately 100 nautical miles of state channels, utilizing single beam sonar rays to determine the depth and 3D contour of the channel bottom to locate debris including sunken vessels, trees, telephone poles etc. McLaren developed over 500 reports consisting of side scan targets of possible debris, which included information such as latitude and longitude, NJ State Plane coordinates, images of objects and approximate dimensions. Data reproduction needed to be accomplished accurately and quickly, and was done so.
