_________________________ADDITIONAL NOTES AND FINDINGS________________________


1) The Patch Test was performed on 09-18-2012 and 10-15-2012.
2) The Multibeam data was collected on 09-28-2012 and 10-19-2012.
3) Laser data is not submitted with this survey.
4) Between River Miles 84.3 to 83.7, there are areas of limited access due to
   barges within the Port Ship Services, Inc., 9-Mile Point Anchorage West
   Bank Landing and Belle Chasse Marine Transportation, Inc., Violet Landing
   vicinities.
5) Due to a higher water surface elevation during the 2012 Revetment survey,
   there is a decrease in bankline coverage of approximately 4.5 foot.
6) There are no sunken objects located within the survey limits.
   
**The following note was established by a comparison of the 2013 Revetment
Bank to Bank Multibeam Survey to the 2012 Revetment Multibeam Survey**

7) There seems to be few areas of accretion and scour.
