Robb and Rachel,
I sampled the stream at our NCSAM points on Wednesday. I apologize for not having a net with me the day we went
out. I have attached the results along with a few pictures and a map of what we are planning to propose.
I also sampled below the perennial point. This is where I found the Gilled Snail in photo IMG 0820. 1 only found one
bug, photo IMG 0814. 1 called this a fly from the Diptera Order. This was found at NCSAM Form 2. Nothing was found
at Form 1.
Form 1 had an overall score of "MEDIUM" for USACE all Streams, and "HIGH" for NCDWR Intermittent. Form 2 had an
overall score of "LOW" for USACE all Streams and "MEDIUM" for NCDWR Intermittent.
On the attached map you will see where I have re -flagged the small wetland area where we hung the flag in the field. I
have moved the pit boundary downstream and we are showing approximately 0.03 acres of riparian wetland impacts
which we would proposed to mitigate for at a 2:1 ratio. I am also showing a point taken approximately 100ft upstream

of the NC SAM Form 1 location. This is where I would propose that we begin mitigation at a 1:1 ratio for 216 linear
feet. We would propose stream mitigation at a 2:1 ratio below the perennial stream point for 104 linear feet.
Please let me know if this mitigation proposal would be acceptable so I can go ahead and reserve credits with Bachelor's
Delight Mitigation Bank.
Thank you both again for your help on this permit! Please feel free to contact me with any questions. My mobile
number is the best way to reach me.

24. Vegetative Composition —First 100 feet of streamside area metric (skip for Tidal Marsh Streams)
Evaluate the dominant vegetation within 100 feet of each bank or to the edge of the watershed (whichever comes first) as it contributes
to assessment reach habitat.
LB RB
A A Vegetation is close to undisturbed in species present and their proportions. Lower strata composed of native
species, with non-native invasive species absent or sparse.
* B B Vegetation indicates disturbance in terms of species diversity or proportions, but is still largely composed of native
species. This may include communities of weedy native species that develop after clear -cutting or clearing or
communities with non-native invasive species present, but not dominant, over a large portion of the expected strata or
communities missing understory but retaining canopy trees.
C C Vegetation is severely disturbed in terms of species diversity or proportions. Mature canopy is absent or communities
with non-native invasive species dominant over a large portion of expected strata or communities composed of planted
stands of non -characteristic species or communities inappropriately composed of a single species or no vegetation.
