Hi Colleen,
I wasn't sure if you were now reviewing this project (Glen at Cool Springs DWR# 20211142), but I've forwarded you our
response to comments that were made by Stephanie back in early September.
Chris Hopper from the Corps had sent us a provisional 404 permit approval, and we are just waiting to hear back from
the State.
Thanks!
Matt

Matt,
I am currently reviewing the above referenced project and have the following items that require clarification:
1. Steam impact 6: the 24 linear feet impact for rip rap seems excessive. Please provide details for why this impact
cannot be minimized [15A NCAC 02H .0506(b)(1)]
2. Stream impact 6: Dewatering-will there be any temporary impacts for dewatering at this stream impact. Please
provide clarification if there will be temporary impact {15A NCAC 02H .0506(b)(1)]
Thank you in advance.

Re: Response to Requests for Additional Information
Glen at Cool Springs (Brownstone)
SAW-2020-01161
(Approx. 55.34 acres)
Lee County, North Carolina
Dear Ms. Goss,
On behalf of Foxfield Atlantic Coast, LLC, we are providing a response to the Request for Additional
Information (RAI) email received on September 2, 2021 for the Glen at Cool Springs, an approximately
55.34-acre site located off of Cool Springs Road in Sanford, Lee County, North Carolina (the Site).
The revised Impacts Maps have been attached showing an increase to temporary wetland impacts, slight
decrease to permanent stream impacts, and the addition of temporary stream impacts to the drawings and
table. Additionally, a Velocity Dissipation Pad (VDP) Design table has been added below the Impacts Table
(Sheet CWI-C1.7). This VDP table provides the calculations for the rip rap pad dimensions associated to
Impact 6.
Temporary impacts to wetlands have increased from 0.071 acres to 0.072 acres to reflect a change in the
position of the pipe for Impact 5. This pipe was originally proposed to maintain the hydrologic connectivity
of the wetland impacted in Impact 5. The pipe was shifted to provide hydrologic input to more of the southern
portion of the wetland. Please note this change was not requested by either the NC Division of Water
Resources or the US Army Corps of Engineers.
For streams, we are proposing a slight decrease to permanent impacts, from 128 linear feet to 127 linear
feet. This decrease is because of a slight shift in the orientation of the proposed 36” RCP. Permanent-no
loss stream impacts remained the same. Temporary stream impacts have been added to the table and
drawings.
The comments provided by the NC Division of Water Resources (NC DWR) are outlined below in italics
and are grouped by question. Our response is below each comment.
1) Stream impact 6: the 24 linear feet impact for rip rap seems excessive. Please provide details for why
this impact cannot be minimized [15A NCAC 02H.0506(b)(1)]:
The design of the rip rap pad dimensions is based on calculations from the NC DEQ Erosion
and Sediment Control Planning and Design Manual chapter 8. The factors used for this
determination include the pipe diameter, velocity, and rip rap zone. The calculations for the
design of the rip rap pad are shown on CWI-1.7. Different orientations and sizes of the pipe
were considered, but the length of the rip rap pad could not be reduced. Please note that the
final proposed design calls for a steeper pipe slope than the original design. However, we are
still proposing that the inlet and outlet of the RCP will not be buried, as per the guidelines of
the new Individual Water Quality Certification.
2) Stream impact 6: Dewatering-will there be any temporary impacts for dewatering at this stream impact.
Please provide clarification if there will be temporary impact [15A NCAC 02H.0506(b)(1)]:
Temporary stream impacts will occur and have been added to the drawings and table (CWI-
1.6 and CWI-1.7). A total of 40 linear feet of temporary stream impacts will be associated with
the dewatering of the stream at Impact 6.
