Response to Comments
SAW-2021-00113 / NCDWR #20201957
Sage Project #2020.23

Please find attached response to USACE comments submitted via email on February 9, 2021.

1. Please provide information to support the delineation upgradient of Pond 1. NCDWR stream form,
NCDWR buffer determination letter, Corps wetland determination data form and photos are some
examples of supporting information that would be helpful for concurrence with the delineation as
submitted.
a. The NCDWR Riparian Buffer Determination Letter has been attached with this response
(NBRRO#19-291). NCDWR staff determined the pond above the origin of Feature A is
not subject. Site photos of the area upgradient of Pond 1 are included.
2. Provide a description to support the proposed riprap fill activity as “no functional loss”. Please
include how the riprap will be installed.
a. The rip rap dissipater pad will be installed so that the rip rap is embedded, and the top of
the rip rap does not exceed the preexisting elevation and matches the preexisting
contours of the channel. A detail of the rip rap dissipater pad has been included. The total
permanent impacts due to the riprap dissipator pad have not changed (30 LF) but are
included in the attached revised PCN Tables.

Norwood Road Subdivision PCN Response Page 2 of 4
3. Based on the information provided in the PCN the existing stream is 5ft wide and based on my
interpretation of the design plans it appears that the proposed design consists of the installation
of (3) 60” culverts at the same elevation. Based on the stream width and design it appears the
proposed project is not in compliance with regional conditions 3.6.2 and 3.6.5.
a. Upon review of data collected by the surveyor and site photographs, the channel at the
impact site measures to be 10-12 feet wide. A photo of the channel just upstream of the
impact site is included.
b. NCDOT has recommended a 137”x87” arch pipe instead of the three 60” pipes. Revised
crossing details and impact maps are included with this response. The total permanent
impacts due to the culvert have not changed (117 LF) but are included in the attached
revised PCN Tables.
4. It appears as though the temporary discharge is less the 202 linear feet requested on the PCN. It
appears as though temporary discharge is limited to the stream channel immediately upstream of
the proposed culvert and downstream of the proposed riprap dissipater.
a. The temporary discharge is 20 linear feet. The revised PCN impact tables have been
included in this response.

If you have any questions, please call me at [phone].

3i. Comments: Total permanent stream impacts due to culvert = 117 LF. Total permanent (no loss) impacts due to a riprap
dissipater pad = 30 LF. Total temporary stream impacts due to dewatering = 20 LF. Permanent impacts are less than 150 LF;
therefore, no mitigation is proposed.

** The pond above the origin of Feature A is not .subject
Explanation: The feature(s) listed above has or have been located on the Soil Survey of Wake County, North
Carolina or the most recent copy of the USGS Topographic map at a 1:24.000 scale. Each feature that is checked
"Not Subject" has been determined not to be a stream or is not present on the property. Features that are checked
"Subject" have been located on the property- and possess characteristics that qualify it to be a stream. There may be
other streams located on your property that do not show up on the maps referenced above but, still may be
considered jurisdictional according to the US Army Corps of Engineers and or to the Division of Water Resources
(DWR).

This on -site determination shall expire five (5) years from the date of this letter. Landowners or affected
parties that dispute a determination made by the DWR or Delegated Local Authority may request a
determination by the Director. An appeal.request must be made within sixty (60) days•of date of this -letter or
from the date the affected party.(iitcluding downstream and/or adjacent owners) is notified of this.letter. A
request for a determination by the Director shall be referred to the -Director in writing if sending via US
Postal Service c/o Karen Higgins DWR — 401 & Buffer Permitting Unit 1617 Mail Service Center Raleigh, NC
2.7699-1617_ If sending via delivery service (UPS, FedEx, etc.) Karen Higgins DWR — 401 & Buffer Permitting

This determination'is final and binding unless, as detailed above, you ask for a hearing or appeal within sixty
(60) days.. i
The'owner/future owners should notify the Division of Water Resources (including any other Local, State,
and Federal Agencies) of this decision concerning any future correspondences regarding the subject property
(stated above). This project may require a Section 404/401 Permit for the proposed activity. Any inquiries
should be directed to the Division of Water Resources (Central Office) at (919)-807-6300, and the US Army
Corp of Engineers (Raleigh Regulatory Field Office) at (919)-554-4884.
