_________________________ADDITIONAL NOTES AND FINDINGS________________________


1) The Patch Test was performed on 12-06-2012.
2) The Multibeam data was collected on 12-13-2012.
3) The Laser data was collected on 12-13-2012.
4) Due to a higher water surface elevation during the 2012 Revetment survey,
   there is a decrease in bankline coverage of approximately 2.5 foot.
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.

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

7) The average difference between the data sets are +/- 0.4 ft.
