I have attached the rev�sed exhib�ts and buffer impact area table for pro�ect#11 0847 and 11 0848
1 The temporary impacts have been revised to include the total limits of disturbance area at both the pro�ect
sites A note will be included on the plans regarding replanting in the buffer zone if altered or disturbed
2 In tabie 6b we have added rip rap area under the permanent buffer impact category Also we have added areas
such as headwalls and greenway extensions in the permanent buffer impacts Please note that the buffer
impacts are measured from the top of the banks
3 Exhibit A has been revised to the show the extents of rip rap and co+r matting Accordingly Table 6b has been
modified to show the updated temporary and permanent buffer impact area
There was slight revision in the plan sets therefore I have attached the pro�ect plans in this email
Please let me know if the revisions are acceptable Once you approve the revisions I will go ahead and mail 5 copies of
this information
