_________________________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 09-27-2012 and 10-19-2012.
3) The Laser data was collected on 09-27-2012.
4) Between River Miles 86.3 to 85.7, there are areas of limited access due to
   barges within the Meraux Ship Buoy and various anchorage vicinities.
5) Due to a higher water surface elevation during the 2012 Revetment survey,
   there is a decrease in bankline coverage of approximately 6 foot.
6) There are sunken objects located at the following mileages/coordinates:
   *RM 85.9 - left bank (3726627.91,519973.71)
   
**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.

**The following note was established by a comparison of the 2012 Revetment
Laser Survey to the 2006 Aerial Laser Survey**

8) The average difference between the data sets are +/- 0.3 ft.
