According to the Soil Survey of Mecklenburg County' (Figure 2. NRCS Soil Survey Map, attached), on -site soils
consist of Cecil sandy clay loam with 2 to 8 percent slopes, eroded (CeD2), Monocan Soils (Mo), Pacolet sandy
loam with 15 to 25 percent slopes (PaE), and Pacolet sandy loam with 25 to 45 percent slopes (PaF).
Cecil sandy clay loam exhibits moderate permeability and a medium available water capacity. Monacan soils
exhibit moderate permeability and a high available water capacity. Pacolet sandy loams exhibit moderate
permeability and low available water capacity. Cecil sandy clay loam and Pacolet sandy loams are well drained
soils. Monacan soils are somewhat poorly drained and are listed in the North Carolina Hydric Soils List for
Mecklenburg County as having hydric inclusions2. Monacan soils (hydric criteria 2B3, 4) are listed as hydric soils
on the National Hydric Soils List3.
Jurisdictional Determination
On October 7, 2011, CWS scientists Thomas Blackwell, PWS and Kelly Hines delineated jurisdictional waters of
the U.S. within the project area. Jurisdictional areas were delineated using the U.S. Army Corps of Engineers
( USACE) Routine On -Site Determination Method. This method is defined in the 1987 Corps of Engineers
Wetlands Delineation Manual4, with further technical guidance from the Eastern Mountains & Piedmont Interim
Regional Supplements, dated July 2010.
Jurisdictional stream channels were classified according to recent USACE and North Carolina Division of Water
Quality (NCDWQ) guidance. These classifications included sampling with a D- shaped dip net, taking
photographs, and defining approximate breakpoints (location at which a channel changes classification) within
each on -site stream channel.
The results of the on -site field investigation conducted by CWS indicate that there are three jurisdictional stream
channels (Streams A, B, and C), one jurisdictional open water area (Pond A), and three jurisdictional wetland
areas (Wetlands AA, BB, and CC) located within the project area (Figure 3, attached). On -Site streams include
unnamed tributaries to Gum Branch. Gum Branch is part of the Catawba River basin (HU# 03050101)6 and is
rated "Class WS-IV Waters" by the NCDWQ. On -Site jurisdictional waters of the U.S. total approximately 4.04
acres. On -Site jurisdictional waters of the U.S. are summarized in Table 1 below.

Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on February 11, 2013 to determine the
presence of any areas of architectural, historic, or archaeological significance that would be affected by the
project. In a response letter dated March 1, 2013 (attached), the SHPO stated that they "....have conducted a
review of the project and are aware of no historic resources which would be affected by the project. Therefore, we
have no comment on the project as proposed". CWS consulted the Charlotte Mecklenburg Historic landmarks
Commission database and found no listed properties within the project area.
Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on February 11, 2013 to
determine the presence of any federally - listed, candidate endangered, threatened species or critical habitat
7 Classifications of streams include Traditionally Navigable Waters (TNWs), Relatively Permanent Waters (RPWs), and Non - Relatively Permanent Waters
(Non- RPWs). subcategories of RPWs include perennial streams that typically have year -round flow, and seasonal streams that have continuous flow at
least seasonally. Two classifications of Jurisdictional wetlands are used to describe proximity and connection to TNWs. These classifications include either
adjacent or directly abutting. Adjacent wetlands are defined as wetlands within floodplains or in dose proximity to a TNW but without a direct visible
connection. Abutting wetlands have a direct surface water connection traceable to a TNW.

located within the project area. In a response letter dated February 21, 2013, the NCNHP stated that, "The
Natural Heritage Program has no record of rare species or natural communities within the proposed project area.
Historical records for 3 rare species are found within a two -mile radius of the referenced project area ". A copy of
the response letter is attached. The species referenced by the NCNHP include tall larkspur (Delphinium
exaltatum), Carolina elktoe (Alasmidonta robusta), and Carolina heelsplitter (Lasigmona decorata). None of these
records have been observed more recently than 1918. Carolina heelsplitter is the only federally- endangered or
threatened species. There is no suitable habitat for this species within the project area.
In addition, the NCNHP Geographic Information Systems (GIS) layer was reviewed for a listing of EOs of
endangered or threatened species within or near the project area. The EO database identified no federally -
endangered or threatened species within a one -mile radius of the project area.
Purpose and Need for the Project
The purpose of this project is to improve dam safety and functionality and enhance water quality at Wilson Pond.
The stream channel downstream of the pond will also be restored and base flow will be reestablished by means of
a 5 -inch water quality orifice in the new pond outlet structure.
The overall conclusion of a visual assessment of the pond was that it was in poor condition due to the general
disrepair of the earthen dam. The upstream and downstream slopes of the dam are excessively steep (2:1 or
greater slopes) and have irregular surfaces due to erosion and/or sloughs and possible animal burrows; there was
also minor rutting along the pond dam crest. The dam has significant trees and vegetation on the embankments
which does not meet standard requirements. No pond outlet conduit or riser structure could be located. An open
channel through the embankment currently serves as the primary spillway. This channel likely served as the
emergency spillway when the dam was originally constructed. The spillway channel is approximately 20 feet wide
with very steep banks. The spillway is currently experiencing severe erosion along the incised banks. The existing
seasonal RPW Stream B downstream of the pond is in poor condition and is not connected to the pond. No
existing pond outlet structure could be located and baseflow has been disconnected from the stream channel
downstream of the pond. The stream lacks year -round base flow, sinuosity, or proper substrate. There is little or
no in -stream habitat. The stream channel is deeply incised, severely eroded, and is not located in a natural
location in the landscape.
This project proposes to raise the dam crest one and a half feet in elevation, extend the dam embankment and
flatten the upstream and downstream slopes to a 3:1 slopes. An outlet riser will be constructed to act as the
primary outlet for the pond. This outlet will incorporate a five -inch water quality orifice to ensure continuous base
flow to the stream channel downstream of the pond.
Due to the extremely low quality of the existing channel downstream of the pond, the project proposes to abandon
the existing channel and to construct a new high quality stream channel between the pond outlet and Gum
Branch. The existing jurisdictional stream channel was formed as a result of water flowing from a breach in the
pond dam. This channel cuts through a side slope of the valley. Since the historic pond outlet collapsed, base
flow to the original stream channel was cut off. Much of this old channel became non jurisdictional as a result.
We are proposing to relocate the stream to its natural position in the landscape (i.e. the valley bottom) where we
believe it was located prior to impoundment. The restored stream channel has been designed using Natural
Channel Design methodologies. Stability will be enhance through the inclusion of in -stream structures, including j-
hooks, step pools, and constructed riffles; the addition of meanders; and planting with Iivestakes of native, woody
plant species. The proposed new pond outlet structure will be configured to sustain base flow hydrology to the
proposed downstream channel through a five -inch water quality orifice.

Avoidance and Minimization
Impacts to on -site jurisdictional waters of the U.S. have been reduced to the maximum extent possible. Proper
sediment and erosion control measures will be used to minimize disturbances to downstream waters. All work will be
constructed in the dry in accordance with Water Quality Certification Nos. 3883 and 3885.
The proposed dam improvement will not change normal pool level. Unavoidable impacts to jurisdictional open waters
are the result of the dam rehabilitation activities and are necessary in order to reduce the inside slope of the dam.
The installation of a proper pond outlet structure will better regulate storm flows and will result in less flashiness in the
system. This fix will reduce erosion, and therefore sediment input to downstream waters.
Impacts to jurisdictional streams will be limited to 316 linear feet of intermittent stream channel and are the result of
stream restoration activities (Figure 4, attached). The stream restoration will relocate the stream to its natural location
in the landscape and will result in a significant functional uplift for the stream channel downstream of the pond.
Additionally, a proposed five inch water quality orifice will be installed under the dam, which will reestablish base flow
to the new proposed outlet channel. Perennial RPWs A, B, and C and wetlands AA, BB, and CC will not be affected
by the proposed work. Wetlands BB and CC should not be adversely impacted by the proposed relocation of Stream
B. The hydrology for these wetlands is primarily driven by high ground water on the floodplain of Gum Branch.
Therefore, the relocation of Stream B should not result in a loss of hydrology to these wetlands.
Proposed Impacts to Jurisdictional Waters
The overall project will involve pond dam and outlet rehabilitation and stream restoration. Unavoidable impacts to
Jurisdictional Waters of the U.S. total 0.21 acre of open water impact and 316 linear feet of impacts to intermittent
streams (Figure 4, attached).
Impacts under Nationwide Permit No. 3
Impacts to jurisdictional waters of the U.S. under Nationwide Permit (NWP) No. 3 totals 0.21 acre of open waters.
These impacts are the result of placement of fill within Pond A necessary in order to accomplish the rehabilitation
of the currently failing dam. The pond rehabilitation involves raising the dam embankment one and a half feet and
reducing the side slopes of the dam to comply with City standards. This will necessitate widening the base of the
embankment and will result in a loss of 0.21 acre of pond surface area. There will be no change to the normal
pool elevation of Pond A (Figure 4, attached).
The pond rehabilitation involves raising the dam embankment one and a half feet to prevent the overtopping which
currently occurs. The side slopes of the dam will be reduced to comply with City standards, which will involve
widening the base of the embankment. There is currently no principal outlet conduit and/or riser structure. A riser
structure will be constructed to act as the principal outlet for the pond (Plan Sheets 6 and 7, attached). A five -inch
water quality orifice will be incorporated into the outlet structure to ensure baseflow to the downstream channel
(Plan Sheet 11, attached). The use of the proposed five -inch water quality pipe and energy dissipater design will
provide improved detention and water quality benefits as compared to existing conditions. The proposed new
pond outlet structures will be configured to sustain base flow hydrology to the proposed downstream channel.
Impacts under Nationwide Permit No. 27
Impacts to seasonal RPW Stream B under NWP No. 27 total 316 linear feet and are the result of the relocation and
restoration of the stream channel (Figure 4, attached). This proposed work will include the construction of a new
channel incorporating natural channel design, installation of in- stream structures, riffles, step pools, and channel
sinuosity (Plan Sheets 16 to 23, attached). The restored stream channel will be 262 linear feet in length resulting in a
net loss of 54 linear feet of intermittent stream channel. The existing channel is in very poor condition with steep,
unstable banks, and lacking baseflow. This channel is in an unnatural location on the side slope of the valley and was
formed as a result of a breach in the pond dam. The proposed new channel will be relocated to its natural position in
the landscape and will represent a significant improvement in stream quality, habitat, and stability. The banks of the

• Wilson Pond Improvement Project April 3, 2013
Nationwide Permit No. 3 and 27 Project No. 2012 -3078
enhanced stream section will be matted with coir fiber matting and live staked with deep rooted, native plant species
to provide bank stability (Plan Sheet 23, attached). A 9'x3' reinforced concrete box culvert will be installed on the new
stream channel to maintain access for the existing sanitary sewer line (Plan Sheet 16, attached). The new channel
will be reconnected with the floodplain to provide energy dissipation. Details of the proposed enhancements are
included on Plan Sheets 16 to 23 (attached). In stream habitat will be vastly improved through the inclusion of
structures such as J- hooks, riffles, and step pools. Finally, the reestablishment of baseflow through the installation
of a five -inch water quality orifice in the pond outlet structure will ensure a significant functional uplift over the existing
condition.
Impacts associated with seasonal RPW Stream B total 316 linear feet and are the result of filling and abandoning the
channel. A new proposed channel, totaling 262 linear feet, will be constructed as the outlet channel for the pond.
Unavoidable impacts to on -site jurisdictional waters are summarized in Table 2, below.

Compensatory Mitigation
Permanent impacts to jurisdictional water of the U.S. under NWP 3 have been limited to 0.21 acre of open water.
Permanent impacts to jurisdictional water of the U.S. under NWP 27 have been limited to 54 linear feet of
intermittent stream channel. Therefore, no mitigation is proposed for these impacts. The project will result in
improved water quality in waters downstream of the pond by reestablishing baseflow to the outlet channel and
removing the existing eroding channel. The project will restore 262 linear feet of stream channel and will result in
a significant functional uplift for this channel.

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 site consists of a pond and surrounding wooded areas. A sewer line runs parallel to Gum Branch at the northern end
of the project area. Typical on -site vegetation includes American beech (Fagus grandifolia), southern red oak (Quercus
falcata), loblolly pine (Pinus Taeda), sweetgum (Liquidambar styraciflua), persimmon (Diospyros virginiana), flowering
dogwood (Corpus florida), Johnsongrass (Sorghum halepense), and poison ivy (Toxicodendron radicans).
3b. List the total estimated acreage of all existing wetlands on the property:
0.60 acre
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
1,373 linear feet of jurisdictional stream channel
3d. Explain the purpose of the proposed project:
The purpose of this project is to improve dam safety and functionality and enhance water quality at Wilson Pond. The stream
channel downstream of the pond will also be restored and base flow will be reestablished by means of a 5 -inch water
quality orifice in the new pond outlet structure.
The overall conclusion of a visual assessment of the pond was that it was in poor condition due to the general disrepair of the
earthen dam. The upstream and downstream slopes of the dam are excessively steep (2:1 or greater slopes) and have
irregular surfaces due to erosion and /or sloughs and possible animal burrows; there was also minor rutting along the
pond dam crest. The dam has significant trees and vegetation on the embankments which does not meet standard
requirements. No pond outlet conduit or riser structure could be located. An open channel through the embankment
currently serves as the primary spillway. This channel likely served as the emergency spillway when the dam was
originally constructed. The spillway channel is approximately 20 feet wide with very steep banks. The spillway is currently
experiencing severe erosion along the incised banks. The existing seasonal RPW Stream B downstream of the pond is
in poor condition and is not connected to the pond. No existing pond outlet structure could be located and baseflow has
been disconnected from the stream channel downstream of the pond. The stream lacks year -round base flow, sinuosity,
or proper substrate. There is little or no in- stream habitat. The stream channel is deeply incised, severely eroded, and is
not located in a natural location in the landscape.
This project proposes to raise the dam crest one and a half feet in elevation, extend the dam embankment and flatten the
upstream and downstream slopes to a 3:1 slopes. An outlet riser will be constructed to act as the primary outlet for the
pond. This outlet will incorporate a five -inch water quality orifice to ensure continuous base flow to the stream channel
downstream of the pond.
Due to the extremely low quality of the existing channel downstream of the pond, the project proposes to abandon the
existing channel and to construct a new high quality stream channel between the pond outlet and Gum Branch. The
existing jurisdictional stream channel was formed as a result of water flowing from a breach in the pond dam. This
channel cuts through a side slope of the valley. Since the historic pond outlet collapsed, base flow to the original stream
channel was cut off. Much of this old channel became non - jurisdictional as a result. We are proposing to relocate the
stream to its natural position in the landscape (i.e. the valley bottom) where we believe it was located prior to
impoundment. The restored stream channel has been designed using Natural Channel Design methodologies. Stability
will be enhance through the inclusion of in- stream structures, including j- hooks, step pools, and constructed riffles; the
addition of meanders; and planting with livestakes of native, woody plant species. The proposed new pond outlet
structure will be configured to sustain base flow hydrology to the proposed downstream channel through a five -inch water
quality orifice.

3e. Describe the overall project in detail, including the type of equipment to be used:
The overall project will involve pond dam and outlet rehabilitation and stream restoration. Unavoidable impacts to
Jurisdictional Waters of the U.S. total 0.21 acre of open water impact and 316 linear feet of impacts to intermittent
streams (Figure 4, attached).
Impacts under Nationwide Permit No. 3
Impacts to jurisdictional waters of the U.S. under Nationwide Permit (NWP) No. 3 totals 0.21 acre of open waters. These
impacts are the result of placement of fill within Pond A necessary in order to accomplish the rehabilitation of the currently
failing dam. The pond rehabilitation involves raising the dam embankment one and a half feet and reducing the side
slopes of the dam to comply with City standards. This will necessitate widening the base of the embankment and will
result in a loss of 0.21 acre of pond surface area. There will be no change to the normal pool elevation of Pond A (Figure
4, attached).
The pond rehabilitation involves raising the dam embankment one and a half feet to prevent the overtopping which currently
occurs. The side slopes of the dam will be reduced to comply with City standards, which will involve widening the base of
the embankment. There is currently no principal outlet conduit and/or riser structure. A riser structure will be constructed
to act as the principal outlet for the pond (Plan Sheets 6 and 7, attached). A five -inch water quality orifice will be
incorporated into the outlet structure to ensure baseflow to the downstream channel (Plan Sheet 11, attached). The use
of the proposed five -inch water quality pipe and energy dissipater design will provide improved detention and water
quality benefits as compared to existing conditions. The proposed new pond outlet structures will be configured to
sustain base flow hydrology to the proposed downstream channel.
Impacts under Nationwide Permit No. 27
Impacts to seasonal RPW Stream B under NWP No. 27 total 316 linear feet and are the result of the relocation and
restoration of the stream channel (Figure 4, attached). This proposed work will include the construction of a new channel
incorporating natural channel design, installation of in- stream structures, riffles, step pools, and channel sinuosity (Plan
Sheets 16 to 23, attached). The restored stream channel will be 262 linear feet in length resulting in a net loss of 54
linear feet of intermittent stream channel. The existing channel is in very poor condition with steep, unstable banks, and
lacking baseflow. This channel is in an unnatural location on the side slope of the valley and was formed as a result of a
breach in the pond dam. The proposed new channel will be relocated to its natural position in the landscape and will
represent a significant improvement in stream quality, habitat, and stability. The banks of the enhanced stream section
will be matted with coir fiber matting and live staked with deep rooted, native plant species to provide bank stability (Plan
Sheet 23, attached). A 9'x3' reinforced concrete box culvert will be installed on the new stream channel to maintain
access for the existing sanitary sewer line (Plan Sheet 16, attached). The new channel will be reconnected with the
floodplain to provide energy dissipation. Details of the proposed enhancements are included on Plan Sheets 16 to 23
(attached). In stream habitat will be vastly improved through the inclusion of structures such as J- hooks, riffles, and step
pools. Finally, the reestablishment of baseflow through the installation of a five -inch water quality orifice in the pond outlet
structure will ensure a significant functional uplift over the existing condition.
Impacts associated with seasonal RPW Stream B total 316 linear feet and are the result of filling and abandoning the
channel. A new proposed channel, totaling 262 linear feet, will be constructed as the outlet channel for the pond.

.D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Impacts to on -site jurisdictional waters of the U.S. have been reduced to the maximum extent possible. Proper sediment and
erosion control measures will be used to minimize disturbances to downstream waters. All work will be constructed in the dry
in accordance with Water Quality Certification Nos. 3883 and 3885.
The proposed dam improvement will not change normal pool level. Unavoidable impacts to jurisdictional open waters are the
result of the dam rehabilitation activities and are necessary in order to reduce the inside slope of the dam. The installation of a
proper pond outlet structure will better regulate storm flows and will result in less flashiness in the system. This fix will reduce
erosion, and therefore sediment input to downstream waters.
Impacts to jurisdictional streams will be limited to 316 linear feet of intermittent stream channel and are the result of stream
restoration activities (Figure 4, attached). The stream restoration will relocate the stream to its natural location in the
landscape and will result in a significant functional uplift for the stream channel downstream of the pond. Additionally, a
proposed five inch water quality orifice will be installed under the dam, which will reestablish base flow to the new proposed
outlet channel. Perennial RPWs A, B, and C and wetlands AA, BB, and CC will not be affected by the proposed work.
Wetlands BB and CC should not be adversely impacted by the proposed relocation of Stream B. The hydrology for these
wetlands is primarily driven by high ground water on the floodplain of Gum Branch. Therefore, the relocation of Stream B
should not result in a loss of hydrology to these wetlands.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Impacts to on -site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable. Proper sediment
and erosion control measures will be used to minimize disturbances to downstream waters. All work will be constructed in the
dry in accordance with Water Quality Certification Nos. 3883 and 3885.

A letter was forwarded to the North Carolina Natural Heritage Program ( NCNHP) on February 11, 2013 to determine the
presence of any federally - listed, candidate endangered, threatened species or critical habitat located within the project
area. In a response letter dated February 21, 2013, the NCNHP stated that, "The Natural Heritage Program has no
record of rare species or natural communities within the proposed project area. Historical records for 3 rare species are
found within a two -mile radius of the referenced project area ". A copy of the response letter is attached. The species
referenced by the NCNHP include tall larkspur (Delphinium exaltatum), Carolina elktoe (Alasmidonta robusta), and
Carolina heelsplitter (Lasigmona decorata). None of these records have been observed more recently than 1918.
Carolina heelsplitter is the only federally- endangered or threatened species. There is no suitable habitat for this species
within the project area.
In addition, the NCNHP Geographic Information Systems (GIS) layer was reviewed for a listing of EOs of endangered or
threatened species within or near the project area. The EO database identified no federally- endangered or threatened
species within a one -mile radius of the project area.
