CWS Project No. 2014-3279:2
DWR: 14-1284
Dear Mr. Johnson and Mr. Elliott:
Thank you for your letter, dated December 23, 2014, requesting a response to comments made by your
office, the North Carolina Department of Environmental and Natural Resources (NCDENR). A copy
of your letter is attached for your reference. This letter is in response to your comments on the project.
Comments are addressed in the same order that they were provided.
The permanent impacts have been further reduced to the maximum extent practicable. Please refer to
the revised PCN (attached).
The site is located within the Goose Creek Watershed and is subject to the Goose Creek
Buffer Rule (15A NCAC 2B . 0600-.0609). More clarification is required regarding the
proposed impacts. Please check the Table of Uses.
Please see the attached Buffer Impact Table for clarification.
A perennial/intermittent stream call may be required. Currently the plan shows a 100 ft
buffer indicating an intermittent stream. Please indicate the buffer on both sides of the
channel (even if offsite).
According Goose Creek riparian buffer rules, “undisturbed riparian buffers are required
within 200 feet of waterbodies within the 100-Year Floodplain and within 100 feet of
1
waterbodies that are not within the 100-Year Floodplain”. Since the site is not within the
100-Year Floodplain, 100 ft buffer applies to the perennial stream.

Response to Request for Additional Information CWS Project No. 2014-3279:2
Please show/indicate on the plan a 50 ft demarcation line within the buffer and its
relationship to the proposed sewer line and trail. A scale drawing may be required.
The proposed trail is completely outside the 50 ft inner line. Figure 1 depicts the 50 ft
demarcation line and its relationship to the proposed the trail and sewer line.
Please indicate the linear ft of sewer line that is located within and outside of the 50 ft line
noted above. Include the square footage for each section of the buffer that is impacted.
This includes the “tether” to the main area of development.
The linear footage of the sewer line within the 50 ft line noted above is 316 lf (4,737 sq
ft). Please refer to the Buffer Impact Table and Figure 1 regarding the length and square
footage of the each impacted section.
Mitigation may be required and a site visit may also be required.
EPCON Communities proposes to mitigate for the permanent riparian buffer impacts (4,737 sq
ft) at a 3:1 ratio through a purchase of 14.211 buffer mitigation units from the NCEEP.
NCEEP acceptance letter is attached.
Please do not hesitate to contact us at 704-408-1683, or through email at [e-mail] should
you have any additional questions or comments regarding this permit submittal.

3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The project area is approximately 50 acres in extent and consists of undeveloped wooded land. Typical on-site
vegetation includes loblolly pine (Pinus taeda), red maple (Acer rubrum), southern red oak (Quercus falcata), winged elm
(Ulmus alata), sweetgum (Liquidambar styraciflua), eastern red cedar (Juniperus virginiana), Johnson grass (Sorghum
halepense), sawtooth blackberry (Rubus argutus), and greenbriar (Smilax rotundifolia).
3b. List the total estimated acreage of all existing wetlands on the property:
0.52 ac
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
139 linear feet of intermittent stream, 5,892 linear feet of perennial stream
3d. Explain the purpose of the proposed project:
The purpose of the project is to develop approximately 50 acres of property into a retirement community consisting of 93
single family homes and to provide sanitary sewer service for the new development. This project will help meet the
increasing demand for retirement communities in the Charlotte region. Impacts to on-site jurisdictional waters are
necessary in order to provide sanitary sewer service to the proposed development.
3e. Describe the overall project in detail, including the type of equipment to be used:
Under Nationwide Permit (NWP) No. 29, unavoidable permanent impacts to jurisdictional waters of the U.S. associated
with this project are limited to a total of approximately 0.052 acre of jurisdictional wetland area and 2.65 acre of Goose
Creek riparian buffer (Figures 1 & 2, attached).
Temporary Impacts
Proposed impacts include installing 8’’ sanitary sewer within the Goose Creek riparian buffer. This will result in a total of
35,143 sq ft temporary impact to the buffer. Installation of the sanitary sewer will also have temporary impact on Seasonal
Stream D (40 lf), Wetland GG (0.011 acre), and Wetland II (0.019 acre) (Figures 1 & 2).
Permanent Impacts
Filling for the purpose of constructing condominium units will result in 0.01 acre permanent impact on Wetland BB (Figure
2). Installation of a Rip Rap apron will cause 0.012 acre permanent impact on Wetland GG (Figure 2). An asphalt path
running through the Riparian Buffer will also cause 0.051 acre of permanent impact (Figure 1). Maintaining the sewer
right-of-way will have 0.011 acre permanent impact on Wetland GG and 0.019 acre permanent impact on Wetland II.
Piping Perennial Stream B with 35'' strormwater pipe will total 45 lf of permanent impact. Typical construction equipment,
such as trachoe, will be used.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The Courtyards at Emerald Lake project has been designed to avoid impacts to jurisdictional waters wherever possible and
minimize the extent of necessary impacts to jurisdictional waters. The following paragraphs outline the avoidance and
minimization efforts undertaken during the planning and design phase of this project.
Avoidance
Jurisdictional Waters of the U.S. have been avoided wherever possible. Impacts were completely avoided on Wetlands AA,
CC, DD EE, FF, HH and most of the Wetland BB remains undisturbed. The proposed trail inside the Goose Creek Riparian
buffer is outside the 50 ft inner part of the buffer to avoid the stream disturbances to the maximum extent possible.
Impacts to the jurisdictional waters and Riparian Buffer are limited to maximum extent practicaple. Constraints on the sewer
route were also taken into account. These constraints include property ownership, site topography, and geology.
Impacts within inner 50 feet from the nearest stream within the Goose Creek Riparian buffer were unavoidable in order to tie in
to the existing system and prevent the sewer going too deep. In areas where impacts to Jurisdictional Waters of the U.S. are
unavoidable, steps have been taken to minimize both the extent and severity of the impacts.
Minimization
Tree removal within the riparian buffer during path construction will be minimal, if not completely avoided. The plan is to
weave the path through the woods avoiding impacts to the trees. Proper sediment and erosion control measures will be used
to minimize disturbances to downstream waters. All unavoidable stream crossings will be at a near perpendicular angle. All
channel work will be constructed in the dry in accordance with Water Quality Certification No. 3890.

7 15A NCAC 02B .0607= Non-electric perpendicular utility line crossings that are collections systems as defined in Rule 15A NCAC 02T .0300: Potentially allowable
without mitigation if using any of the following installation methods to minimize the sediment, nutrient and other pollution through the riparian
buffer: underground directional boring methods, bore-and-jack techniques or another appropriate microtunnelling method.
