RE: High Hampton Redevelopment
DWR # 20180765 Ver 3
Jackson County, North Carolina
Ms. Higgins,
Please reference the Ietter dated August 15, 2019 sent by the NC Division of Water
Resources (DWR) in response to the permit application submitted by C1earWater
Environmental Consultants, Inc. (CEC), on behalf of Daniel Communities. The permit
application requested authorization for the impacts associated with the High Hampton
Redevelopment Plan. The comments provided by the DWR in response to this plan are
listed and discussed below.
NC Division of Water Resources comments:
1. The review of the project cannot be completed until the Public Comment period has
closed and the Division can review any comments received. If the U.S. Army Corps of
Engineers requests a response to any comments received as a result of the Public
Notice, please provide the Division with a copy of your response to the USA CE. [15A
NCAC 02H. 05 02 (c)]
The public comment period closed August 19, 2019. All responses to comments
received from the U.S. Army Corps of Engineers will be also be provided to the
Division of Water Resources.
2. The culvert that was installed at After -the -Fact stream impact #14 is perched at the
outlet and therefore it does not meet the requirement to provide for low flow passage
of aquatic life. Please provide a remediation plan for this culvert location which will
support aquatic passage. [ISA NCAC 02H .0506(b)(2)]
Please find the attached Figures — UT2 Enhancement Plan & Profile and Details
(Attachment A) which proposes the installation of boulders steps to create step pools
to correct the perched culvert shown in the attached photographs located at stream
