Hello Colleen - Thanks for these links They were very so helpful.
1 - I have the army corp response attached. (Just FYI - I would like to continue to secure the permit for coir
however we'll likely progress with rip rap rather; already permitted under DWR#20210738).
2 - I updated the plan view in attached Slide 1 as you're right, I had the 20' vs 30' switched in the Zones.
3 - I'm waiting on some pricing for mitigation credits and working with one of the private banks.
4 - Concrete pavers example is on Slide 4. The engineer confirmed no need for a french drain as the pavers
would work as a 'dry creek' and allow water flow with maintaining stabilization and prevent erosion without
dispersing or consolidating waterflow.
5 - The timber border shown on Slide 3 also stabilizes the shoreline and maintains the same outflow of water as
it's not a 'wall' really but stabilizes and maintains the slope as it's currently eroding quickly.
I've reached out to a mitigation bank to start the process but I was curious if since the "Use" of this land was for
parking and turnaround as of 1991 before buffer rules were established... Is it possible for DWR to issue a letter
that the Use of this land was in existence and exempt? This area was cleared of vegetation and was impervious
clay with the timber border prior to the project so the 'Use' itself did not change just in this instance.
I also wondered if by salvaging our shoreline, onsite mitigation could be considered otherwise? I can certainly
move forward with bank credits but did want to see if you thought PRM was an option in this case as we're not
only stabilizing, adding vegetation but on the other side of our property have gained the permit to stabilize that
shoreline which has previously eroded several feet in the 6 years of owning and we have just lost another tree
last month. The rip rap project will prevent further losses (permitted DWR #20210738). Would that be a
consideration if the Use is not considered existing?
Thanks for the time reviewing this! Feel free to call if you would like to ask or confirm anything quickly.

Hi Laura,
I am beginning my review for this project, and I need some additional information to complete my review:
1

1. Have you spoken with the US Army Corps of Engineers concerning the use of coir logs? If so, can you please
provide a copy of the correspondence?
2. I'm having a difficult time reading the plan view for the concrete driveway. The labels are blurry, but it looks like
the line indicating the end of Zone 1 is approximately 20 feet from the edge of bank, not 30 feet. The two labels in Zone
1 appear to read 17.5' and 22.5' respectively. Please provide a vicinity map with clearer labels that confirm that the
location of Zones 1 & 2. Additionally, please confirm the impact amounts within Zones 1 and 2.
3. It appears that the concrete work for the driveway addition falls under Driveways — Impacts other than
perpendicular crossings of streams, which is Allowable with Mitigation Upon Authorization [15A NCAC 02B
.0714(11)(x)]. After confirming the impact amounts within Zones 1 and 2, you must seek mitigation from a private
mitigation bank and then, if not available, the NC Division of Mitigation Services can be contacted. You can view
mitigation banks here: https://deq.nc.gov/about/divisions/water-resources/water-quality-permitting/401-buffer-
permitting-branch/nutrient Please provide a statement of availability from a private mitigation bank.
4. Please provide more detail concerning the "concrete or pavers near asphalt" and the "French drain" mentioned in
the vicinity map. What is the purpose of the concrete/pavers?
5. Please provide more detail concerning the 18" timber wall. What is the purpose of the wall? Would this prevent
the dispersed flow of stormwater through the buffer?
Thank you,

Hi Colleen - I don't want to bother you and I'm sure my project is still in queue. I've got a
submission going to my HOA for yard improvements and would love to have your review by
then but I completely understand if I just didn't get in queue fast enough. Just wondering if you
anticipate feedback anytime this week? Really do hate to bother you, I'm sure all projects are
pressing!
Kind Regards,
