_________________________ADDITIONAL NOTES AND FINDINGS________________________


1) The Patch Test was performed on 04-11,24-2013.
2) The Multibeam data was collected on 04-24,25-2013.
3) Laser data is not submitted with this survey.
4) Due to a lower water surface elevation during the 2012 Revetment survey,
   there is an increase in bankline coverage of approximately 17.5 feet.
5) 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**

6) There seems to be few areas of accretion and scour.
   a) Ranges U-130 to U-125 (edge of mat), Manchac revetment, there is an area
   	that has an increase in elevation ranging approximately 15 feet to 27
