01836
All,
Thank you for your PCN, dated 4/15/2021, and project plans received via email on 4/29/2021, for the above referenced
project. I have reviewed the information and need clarification before proceeding with verifying the use of Nationwide
Permit (NWP) 29 (https://saw-reg.usace.army.mil/NWP2021/NWP29.pdf). 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the Nationwide Permit or consider your application withdrawn and close the file:
1) Based on the "Environmental Impacts Overview (Sheet 1) it is unclear how both access and home/attendant
features construction will occur on lots 12 and 14 without requiring additional impacts to Stream SA. Please
explain/show how access to these lots and reasonably sized construction/disturbance envelopes will be
achieved without requiring additional impacts to this stream. It may be useful to provide the expected built
upon area for these lots and to sketch these footprints onto Sheet 1. For Lot 14 in particular how will the future
Lot buyer access all of their property without requiring an additional crossing of this stream?
i

An updated set of the impact drawings is attached. The engineer has shifted the lots to allow for more buildable
area and access for lots 12 and 14. The building setbacks were kept uniform and included a stream buffer 15'
from the approximate OHWM. They also include approximate house footprints offset a minimum of 10' from
the stream buffer area to allow for adequate room during construction. An approximate driveway location has
been shown for lot 12.
2) The PCN notes that this is a phased project, and the applicant owns all adjoining parcels to the east and
southeast of the proposed project area. Furthermore, the hammerhead shown to the east of the proposed
impact area is located on one of those off -site parcels. Although the PCN notes that there are no immediate
plans to extend the subdivision to the east, do any of the future phases require impacts to Stream SA or other
potential waters of the US? Have any conceptual or master plans been developed that show full build out of this
phased development? Please provide this information pertaining to the full phased project, as the Corps will
consider all proposed/foreseeable impacts for this development as cumulative when considering NWP and
compensatory mitigation thresholds, and our regulations do not allow "piecemealing" to avoid these limits.
There are no conceptual or master plans that have been developed that show full build out of a phased
development. The hammerhead is required for fire access according to Appendix D of the 2018 NC Fire
Prevention Code. The road was extended to provide access to these parcels. While no future development is
proposed at this time, any future development should it occur, will seek to avoid impacts to jurisdictional
features, and the developer understands that any future impacts will be considered cumulative with the impacts
being proposed currently. The developer acknowledges that the Corps will consider all proposed/foreseeable
impacts for this development as cumulative when considering NWP and compensatory mitigation thresholds.
Please let me know if you have any questions.
Sincerely,
Dave Bailey
