Ross,
Per your request for additional Avoidance and Minimization, the project engineers and applicants have updated the proposed plan to avoid all previously proposed wetland impacts and have
minimized the riparian buffer impacts at impact locations A-1 and F-1.

At impact area A, the SCM Discharge Outlet has been pulled back to avoid all wetland impacts.

At impact area F, the project engineers have redesigned the greenway crossing to be a boardwalk crossing with pile driven piers, therefore avoiding the wetland impacts.

In our meeting dated June 18, 2019, we discussed impact area E and the additional justification to support the purpose and need for this road crossing. In your email below, you have
agreed to the additional justification provided. Specifically, the purpose and need for this impact is due to the proposed project being constructed in two phases. Per the construction
phasing plan, Phase 1 which is the southwest portion of the project and includes approximately 38 lots, will need two points of ingress/egress. These two points include the proposed
crossing at Phlox Road and Buffalo Road. Per the NC State Fire Code Appendix D, Section D107, subdivisions that propose more than 30 lots requires two points of ingress/egress. https://codes.iccsafe.org/content/NCFC2018/appendix-d-fire-apparatus-access-roads

We have updated the Pre-Construction Notification Application and the Impact Map set. Please see attached.

If you have any questions or need anything further, please do not hesitate to give me a call.

Thank you,
Debbie

Hey Debbie,

As always, it was a pleasure to speak with you and your clients earlier today. With regards to impact site E (the connection to Phlox Road), the Corps has determined that the applicant
has a justifiable purpose and need for this impact due to the proposed project being constructed in two phases. According to our discussion today, Phase 1 would develop the southwest
portion of the project to include roughly 38 lots and have two points of ingress/egress (Phlox Road and Buffalo Road). Information presented in the meeting indicate that the City of
Raleigh requires two points of ingress/egress for subdivisions of over 30 lots.

With regards to compensatory mitigation, the overall permanent impacts to streams that cause a permanent loss of waters for this project is 149 linear feet, which is very close to, but
under, the mitigation threshold listed in the 2017 Regional Conditions associated with NWP 29. The Corps is not requiring compensatory mitigation for the proposed impacts associated
with this project. However, as we discussed today, the Corps will likely attach special conditions to the NWP 29 verification for this project to request (1) a pre-construction meeting
with the applicant and their contractors to discuss the mitigation thresholds, and (2) a post-construction survey of the stream impact areas to show the actual impacts versus what was
proposed. If the impacts exceed the mitigation threshold of 150 LF, the project would not be in compliance with the NWP verification and the applicant would need to either redo the crossing
so that the impacts match the authorized lengths or request authorization for the additional impacts and provide compensatory mitigation for all of the permanent stream impacts causing
permanent loss associated with this proposed development.

Thanks for the efforts to avoid impacts at Impact Site A-2 and F-2. I will begin reviewing the project once you submit revised plans and impact totals for the proposed project.

Please feel free to reach out with any questions or concerns.

Sincerely,

Ross,
I have talked with the applicant and the project engineers, we are working through some revisions to actually avoid the wetland impacts. Minimizing the stream impacts however are more
difficult. When I started reviewing the impact maps with them the permanent stream impacts were over 200 LF so they have minimized quite a bit. In hindsight I should have expressed
that in the application.

We would like to request a meeting to review the stream impacts, where they started and how then ended up where they are and the City of Raleigh development regs that they are required
to design around. If you are amenable to that, we wanted to see if a June 20th date would work for you, possibly in the morning. If that date does not work for you, if you wouldn't
mind providing us a few options so that I can coordinate with the applicants and engineers.

One more thing, Bohler Engineering offered to host the meeting. I do not know if that works for you, please just let me know.

Hey Debbie,

Thank you for the Pre-Construction Notification (PCN) and attached information, dated and received 5/7/2019, for the above referenced project. I have reviewed the information and need
clarification before proceeding with verifying the use of Nationwide Permit (NWP) 29. Please submit the requested information below (via e-mail is fine) within 30 days of receipt of
this Notification, otherwise we may deny verification of the use of the NWP or consider your application withdrawn and close the file:

1. Impact Site A-2 - SCM Discharge Outlet: Can these impacts be minimized and/or avoided by outletting the pipes in uplands? If not, please provide justification why the proposed plan
is the necessary design. Also, According to the 2017 Additional Regional Condition 4.1.1 for NWP #29, discharges in perennial streams, intermittent streams, and wetlands for stormwater
management facilities are prohibited. Since these pipes are outlet structures for stormwater management facilities, this activity would be prohibited under NWP #29.

2. Impact Site E - Road Crossing: The plans submitted with the PCN application propose three road connections for the proposed residential subdivision: to the south at Buffaloe Road,
to the west to Old Milburnie Road, and to the east to Phlox Road. The connection to Phlox Road would result in Impact E. According to the PCN application, "Impact Site E is a proposed
road crossing necessary for access to the property from an existing stub." Please provide further justification to support the need for the impacts to perennial stream (UT to Hodges
Mill Creek) that would result from connecting the proposed subdivision to the Phlox Road stubout when there are two access points proposed for the subdivision (at Buffaloe Road and Old

Milburnie Road) that would not require impacts to any potential waters of the US?

3. Impact Site F-2 - Greenway Trail: Provide further justification for this impact. Specifically, can this stretch of greenway trail be constructed using alternative methods such as
a boardwalk to minimize/avoid impacts? Also, why is it necessary to connect the subdivision with a greenway trail at this location?

Note that the total permanent loss of stream bed for the proposed project is 149 linear feet of stream impacts which is very close to the mitigation threshold of 150 linear feet typified
by the 2017 Regional Condition 3.2. The Regional Condition 3.2 also states that the "District Engineer may determine, on a case-by-case basis, that compensatory mitigation is required
to ensure that the activity results in minimal adverse effect on the aquatic environment." Further efforts at avoidance and minimization for this project can help to ensure that the
proposed project only results in minimal adverse effect on the aquatic environment.

Please feel free to contact me with any questions or concerns.

Sincerely,

Ross
