SUBJECT'. RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION
Mr. Brown:
Attached are revised plans And other attachments which attempt to address the comments received byUWE, U.S. Fish -
and Wildlife (USFW), N.C. Division of Water Resources (NCOWRI, and the N.C. Wildlife Resources Commission (NCWRC).
USACE f USFW Response::
Attached is a revised application ineludingthe:applicant's agent's signature and Pians are submitted in '.11'*17"17ormat,
Per the revised plans, natural stream rehabilltationlrestoration has been implemented to the extent possible for the
stream reach. The siream channel and banks incorporate co Ir fiber based matting, live staking and%r plantings, and
native stone to the ektent possible to provide both a natural and stable system.
Pians indicate how sediment Impacts to the stream including adverse Impacts to the downstream presence of
endangered species will be minimized by Using several methods Including diking for working in the dry, In -stream
sediment trapping, and erosion control and burp methods as construction: progresses.
NCDW R / NCWRCResponse:
Quarry based Rip Rap asthe sole means of stream stabilization have been removed and replaced with native cobble
stone stream bed and bank material, bioengineered Colr4 ber based matting, live staking, tree and shrubbery planting..
Weare in the process of receiving a letter granting permission to enter the Lowes property to perform the work.
As stated previously, becauseof the size of thestroam it appearsto be possible use coir fiber logs to direct the stream to
one side of the stream while crows work withinthe dry, area, Please refer to plan details. Work within the stream is as
proposed by the plansIs to be done as quickly ars possible with daily inspection of sediment control measures and
removal if necessary.

August 5, 2016
Sediment removal and a detailed riparian plan are addressed on Sheet C.1 of the proposed plans. The longitudinal
:profile for the impacted reach and existing cross sections including proposed channel cross sections are shown on sheet,
C.2 ofthe plans.
The stream bed will be stabilized by incorporating native nibble store material and cross vanes forgradecontrol,
Channel location is based on the extremely limiting conditions present due to existing utilities andstructural walls which.
confine the stream both vertically and horizontally to its present location; The entire stream as located presently is
within a 15' TucRaselgee Waterand Sewer Authority utility easement. Within the easement is an existing gravity tahitafy
sewer line to the West and running parallel and in close proximity With the stream. The lineandthe easement limits the
amount of rehabilitation that can be performed as the easement must be blearfor maintenance access. The retainlpg
wall to the East and parallelingthe -stream limits the horizontal location of the stream on that side of the stream . Asa
matter of structural integrity of the wall and to limit possiblefuture stream issues, the stream should be located as far
away from the wall as"the constraints allow, which in my professional opinion is the stream's present location. Finally,
vertical limitation's include' both the existing sanitary sewer line paralleling the stream, the crown of which Is
approximately 1 foot or less below the stream bottom. Further, at the downstreamend of the affected reach an existing
sewer line crosses- the Stream for which the crown appears to be exposed. Both of these issues limit the vertical location
to where it presently exists.
lftl ere are any questions by any agencies, please contact meat your earliest convenience..
