Dear Ms. Higgins:
Please find enclosed five copies of our PCN package for the subject project. We have included the
following supporting data:
• PCN form,
• 11" x 17" copies of the Draft plan set,
• $240.00 in payment fees for each project.
• Also included is a recently submitted cover letter to David Bailey with the US Army Corps of
Engineers addressing comments from his email to Wildlands Engineering dated January 4, 2016.
The goals of the project are to
• Restore and enhance appropriate in -stream habitat,
• Improve aquatic species migration routes.
This same information has been submitted to the Raleigh Regulatory Field Office of the US Army Corps
of Engineers. If you have any questions, please call me at 919-851-9986, ext 105.

Subject: Pre -Construction Notification Pursuant to Nationwide Permit No. 27

Indian Valley Crib Dam Removal and Granite Mill Crib Dam Removal
Alamance County, North Carolina
Dear Mr. Bailey:
Please find enclosed one revised copy of our design plans for each of the subject projects referred to
above. Also, below I have included your comments and Wildlands' responses from your January 4,
2016 email regarding our original permit application package.
Both Projects:
1) Please further explain how the dam removal areas will be accessed. Will parts of the river be
dewatered? Will temporary roads for construction equipment be constructed in the river? If so, where,
and with what materials? Any temporary impacts must be accounted for in the proposal.
Wildlands response:
For each site, the access will be through the designated haul road as shown on the plans. River access
will be limited to the disposal areas and the crib dams. No portions of the river will be dewatered while
removing the dams. Construction is scheduled for mid -summer when the river levels will be lower than
normal.
No roads will be constructed in the river. While in the river, equipment will be confined to the footprint
of the crib dam walls as much as possible. Any access outside of the crib dams will be limited to a
narrow corridor between the crib dam walls.
2) What will be the finished substrate? Will any stabilization be needed following material removal?
Wildlands response: The finished substrate will consist of native rock material which was used to
backfill the crib dam walls. This material is consistent in size with nearby, native bed material and
should not need any additional stabilization.
Wildlands Engineering, Inc. • phone [phone] • 312 West Millbrook Road, Suite 225 • Raleigh, NC 27609

3) Will any rock disposed along the river bank reach below the ordinary high water mark? Is this
material needed for bank stabilization? Please explain, and update proposed impacts if necessary.
Wildlands response: We anticipate that all rock material inside of the crib wall dams will be placed in
the voids created with the removal of the crib wall timbers. In the event that there is excess material
generated when removing the crib walls and the backfill between the dams, this material will be
disposed of along channel banks in areas shown on the plans. This steam length was accounted for in
the stream length impacts. Please note that Wildlands does not anticipate a large amount of material if
any to be disposed of in these areas.
4) Please coordinate with the North Carolina State Historic Preservation Officer regarding Section 106
of the National Historic Preservation Act to determine if either dam has any historic significance. Please
contact Renee Gledhill -Early of the NC Department of Cultural Resources at
Environmental.Reviewnncdcr.gov, making sure to include pertinent information about the proposed
projects to aid in her determination. Please forward the response to me when received.
Wildlands response: We have contacted the North Carolina State Historic Preservation Office and will
forward their response to you when we receive it.
Indian Valley (SAW -2015-02644):
1) Please provide more information about the proposal to "grade stream channel to direct flow to
powerhouse structure as directed by the engineer." How will this grading affect river flow during low
flow events?
Wildlands response: Upon completion of removal of the crib dam walls, if no water is flowing near the
existing powerhouse, a small, narrow flow path may be constructed to allow a portion of the base flow
to move toward the powerhouse. This path will only alter the flow path of a small portion of the flow
within the main channel.
This same information has been submitted to the NC Division of Water Quality. If you have any
questions, please contact me at 919-851-9986, ext 105.
Sincerely,
Daniel Taylor

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The project will result in improvements to aquatic habitat in the Haw River and its tributaries. From aerial photography field assessment, the amount of
backwater as a result of the crib dam is approximately 500 feet upstream. This short amount of backwater and the low elevation of the cribbing will
result in minimal effect of upstream drainage features. The construction activities shown on the design plan were placed to have minimal disturbance
to existing vegetation and stream banks.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Removal of the dam is proposed to be completed during the late summer of 2016. Removal in the summer should allow for the water level in the river
to be near its lowest elevation. Access points to the river will be stabilized and monitored frequently for sediment loss. All disturbed areas of the
project will be stabilized prior to completion of construction activities.
Construction practices will follow guidelines from the NC Erosion and Sediment Control Planning and Design Manual.
