Brad, please copy me when you respond to this email. I will consider the application on hold until receipt of the
information requested by the USACE. Thank you.

Thanks for the application and additional information provided below. I've got a few follow-up requests to aid in our
review.
1) The previous permit verification authorized the loss of 0.247 acre of Waters of the United States (combined
stream (0.004 ac) and wetland (.243 ac) loss). In addition to the temporary/permanent stream crossing(s)
requested, stream impacts are show underlying future home sites. Please clarify why mitigation for stream
impacts is not proposed? A conceptual build -out exhibit with future impacts estimated would be helpful.
2) Impact locations aren't clear on the exhibits provided. It appears the temporary and permanent stream
crossings would occur in the same location; please confirm. The upstream invert elevation of the temporary
pipe is more than a foot higher than the upstream invert of the permanent pipe, so if these would be in the
same footprint it is confusing.
3) The total stream impact of the currently proposed project, 41 linear feet (Stream Impact Table), doesn't match
other information shared. Can you please confirm this is correct?
i

4) The application states that the temporary crossing would be used for six to nine months and removed prior to
installation of the permanent culvert. Temporary discharges cannot be placed in waters for more than six
months without specific written permission from the Corps. It's conceivable that timelines or availabilities may
factor into the reasoning, but can you elaborate on the need for this approach? What duration of time is
anticipated between removal of the temporary pipe, and installation of the permanent one?
5) We appreciate the consideration of not burying the culvert due to slope and bedrock, but the proposal doesn't
meet the condition referenced in your response to NCDWR ("Culvert burial is not required for structures less
than 72-inch diameter/width, where the slope of the culvert will be greater than 2.5%, provided that all
alternative options for flattening the slope have been investigated and aquatic life movement/connectivity has
been provided when possible (e.g., rock ladders, cross vanes, sills, baffles etc). Culvert burial is not required
when bedrock is present in culvert locations.").
The slope is less than 2.5% and dual 66-inch culverts aren't consistent with the 72-inch threshold. If a
photograph or supporting design information is available to document our approval based on bedrock it
would be helpful. What considerations were made to provide for aquatic life passage?
Please see below and let me know if there are questions or concerns.

Sue —based on the scaled cross section (Impact Drawings 4 of 4, Page 19 of PCN), the culvert slope is at or near 2.5%.
The proposed culvert was designed to meet NCDWR GC 4256 Condition 11, paragraph 3 in addition to NWP 29,
condition 9, a.
Also noteworthy, based on our field visits and familiarity with the site, there are exposed rock outcrops at grade within
the proposed culvert footprint.
Please let me know if you require additional information. Thanks.

Brad,
It appears that the permanent culvert is proposed to be installed at grade rather than buried but I don't see where a
justification was given or a slope provided on the plan sheet so I could make that assumption. Can you please either
provide a plan sheet that revises that to show culvert burial, or provide a justification for not providing burial.
Thank you
