Current Land Use
The current land use for the project area consists primarily of wooded floodplain with adjacent
residential areas and mowed lawns. Dominant vegetation within the project area consists of sweetgum
(Liquidambar styraciflua), box elder (Acer negundo), green ash (Fraxinus pennsylvanica), sycamore
(Platanus occidentalis), tulip poplar (Liriodendron tulipifera), Chinese privet (Ligustrum sinense), and
poison ivy (Toxicodendron radicans). According to the Soil Survey of Mecklenburg County1, on-site
soils consist of Cecil sandy clay loam (CeB2), Wilkes loam (WkE and WkD), and Monacan loam
(MO). Cecil and Wilkes soils are well-drained, while Monacan soils are somewhat poorly-drained.
Monacan soils are listed by the NRCS as soils with hydric inclusions for Mecklenburg County2.
Jurisdictional Delineation
On May 21, 2008, August 12 and 14, 2008, and April 29, 2009 scientists from CWS delineated (flagged in
the field) and classified on-site jurisdictional waters of the U.S. using the U.S. Army Corps of Engineers
(USACE) - Routine On-Site Determination Method. This method is defined in the 1987 Corps of

1 United States Department of Agriculture, 1971. Soil Survey of Mecklenburg County, North Carolina.

Engineers Wetlands Delineation Manual.3 There are five jurisdictional wetland areas located within the
project area (Wetlands AA-EE). Routine On-Site Data Forms representative of Wetlands AA – EE and
adjacent upland areas are enclosed (DP1 – DP7). Jurisdictional stream channels were classified according
to recent North Carolina Division of Water Quality (NCDWQ)4, USACE, and U.S. Environmental
Protection Agency (USEPA) guidance. NCDWQ Stream Classification Forms and USACE Stream
Quality Assessment Worksheets representative of Streams A – D have been enclosed (SCP1 – SCP4).
NCDWQ Stream Classification Forms representative of non-jurisdictional features have also been enclosed
(SCP5 and SCP6) and a USACE Approved Jurisdictional Determination Form has been included for
Stream A.

The results of the on-site field investigation conducted by CWS indicate that there are four
jurisdictional stream channels (Streams A, B, C (McAlpine Creek), and D), five jurisdictional wetland
areas (Wetlands AA – EE), and one jurisdictional open water area (Pond FF) located within the project
area (Figure 1, enclosed). On-site jurisdictional waters include McAlpine Creek and unnamed
tributaries to McAlpine Creek. McAlpine Creek is within the Catawba River basin (HU # 030501035)
and is rated “Class C waters” by the NCDWQ. Linear footage and acreage of on-site jurisdictional
waters are summarized in Table 1, below.

Open Water Areas
Pond FF (approximately 1.56 acres) is located on the northern side of McAlpine Creek (Figure 1, enclosed).
Pond FF is a man-made pond serving as a storm water detention pond for an apartment complex. Pond FF
has a hydrological connection to Wetland CC.

Non-Jurisdictional Features
Additional drainage features are located to the south of McAlpine Creek and were investigated during the
field survey. These features both displayed a discontinuous bed and bank. These features were determined
to be non-jurisdictional ephemeral drains and scored 7.5 and 13.25 out of a possible 71 points on the
NCDWQ Stream Classification Form, indicating non-jurisdictional ephemeral status (SCP5 and SCP6).
Representative photographs of these non-jurisdictional drains are enclosed as Photographs G and H.

Routine On-Site Data Forms representative non- jurisdictional upland areas have been enclosed (DP1,
DP2, and DP6).

Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on June 9, 2008 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 July 21, 2008 (enclosed), the SHPO stated that they
“are aware of no historic resources that would be affected by the project.”

Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on June 9, 2008 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 June 18, 2008 (enclosed), the
NCNHP stated that they have “no record of rare species, significant natural communities, significant
natural heritage areas, or conservation/managed areas at the site nor within a mile of the project area.”

Purpose and Need for the Project
The main stem of McAlpine Creek between Sardis Road and Providence road is deeply incised, and
has been dredged and straightened in the past. It has characteristics of an ‘improved’ storm drainage
channel, particularly in the upper part of the stream near Sardis Road. This portion of the mainstem has
virtually no sinuosity, pattern or definable pools and all riffles are heavily embedded with sand and
silt. Banks average 90 degrees or more and are mostly denuded. About halfway between Sardis and
Providence Roads (proposed stream station 32+00) the stream does meander slightly and steepens,
which has exposed some bedrock. The quality of the riffle substrate, riffle/pool patterns, etc. are still
poor along this reach but superior to the upstream portion.

The purpose of this project is to conduct stream restoration and enhancement on McAlpine Creek and
two unnamed tributaries to McAlpine Creek (SR2 and SR3) which are also in degraded condition. The
primary goals of this stream restoration are: (1) to improve water quality by reducing total suspended
solids (TSS) and nutrient loading; and (2) lessen structural flooding downstream by creating more
geomorphologically stable channels throughout the project area while improving and restoring their
hydrologic connection to their floodplains. In addition, the project will restore aquatic and terrestrial
habitat and enhance recreational and educational opportunities as well as provide flood water storage
and create mitigation credits. Wetland construction will also be conducted on the floodplain of
McAlpine Creek with the purpose of improving water quality. Temporary impacts to on-site
jurisdictional waters are necessary to alleviate channel erosion and enhance aquatic habitat.

Pond FF will be retrofitted as a multi-cell storm water treatment wetland. In addition to providing
improved storm water treatment this will result in improved habitat diversity and quality.

Additionally, a greenway trail is proposed for construction adjacent to McAlpine Creek. This
greenway trail will extend the existing greenway trail located to the east of Sardis Road. The proposed
trail will link Providence Road to the existing Mecklenburg County greenway trail network. There
are no impacts to jurisdictional waters associated with the construction of the greenway trail.

Avoidance and Minimization
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable.
Restoration work will result in an improvement in stream stability and ecological function. The proposed
greenway trail has been designed to completely avoid impacting existing wetlands. There is one
unavoidable stream crossing associated with the construction of the greenway trail. This crossing will be
accomplished with a bridge and will not result in any impacts to jurisdictional waters. Proper sediment
and erosion control measures will be used to minimize disturbances to downstream waters. All channel
work will be constructed in the dry in accordance with Water Quality Certification No. 3689.

Proposed Impacts to Jurisdictional Waters
Unavoidable impacts to Important Intermittent Seasonal RPW Stream A total approximately 395 linear
feet and are the result of a Priority 1 Stream Restoration. Intermittent Stream A will be relocated to a new
geomorphically stable channel as shown in Plan Sheet SR3-1 (attached). The proposed new stream
channel is approximately 370 linear feet in length, resulting in a net loss of 25 linear feet of intermittent
stream channel. The proposed new stream channel will result in significant improvements in the quality
of Intermittent Stream A. The existing channel is a deeply incised Rosgen type ‘G’ channel that is
experiencing moderate to severe erosion. The proposed new channel will exhibit improved floodplain
access and improved sinuosity. In-stream structures and constructed riffles will increase stream habitat
diversity and improve channel stability, resulting in a high level of functional lift throughout the reach. A
plan view, longitudinal profile, and typical cross-sections of the proposed new channel are shown on Plan
Sheet SR3-1 (attached).

Unavoidable impacts to Perennial RPW Stream B total approximately 2,060 linear feet and are the result
of stream restoration. A new geomorphically stable channel is proposed for Perennial Stream B. The
proposed new stream channel is approximately 2,235 linear feet in length, resulting in a net gain of 175
linear feet of perennial stream channel (Plan Sheets SR2-5 and SR2-6, attached). The proposed new
stream channel will result in significant improvements in the stability and ecological function of Perennial
Stream B. The proposed new channel exhibits improved channel dimension, pattern, and profile. Habitat
enhancement will be based on profile and dimension changes to improve pool depth, riffle/pool ratio
and reduce riffle embeddedness. Root wads and wood J-hooks are meant to introduce large woody
debris (LWD) permanently in this stream. In-stream structures and constructed riffles will increase
stream habitat diversity and improve channel stability, resulting in a high level of functional lift
throughout the reach. Plan views, longitudinal profiles, and typical cross-sections of the proposed new
channel are shown on Plan Sheets SR2-1 to SR2-7 (attached).

Unavoidable impacts to Perennial RPW Stream C (McAlpine Creek) total approximately 5,148 linear feet
and are the result of stream restoration. A new geomorphically stable channel is proposed for Perennial
Stream A. The proposed new stream channel is approximately 5,322 linear feet in length, resulting in a
net gain of 174 linear feet of perennial stream channel (Plan Sheets MS-1 to MS-10, attached). The
proposed new stream channel will result in significant improvements in the stability and ecological
function of Perennial Stream C (McAlpine Creek). The proposed new channel will exhibit improved
channel dimension and profile. Habitat enhancement on McAlpine Creek will be through the use of
sills installed to increase scour holes and pool areas (as is the case under current conditions where tree
stumps exists at the toe of slope). These sills will also promote inner berm bar growth and riffle
creation. Live stakes and other vegetative installations at the toe of slope will also trap floatable
vegetative material, particularly leaves which will provide better benthic feeding sources. Plan views,
longitudinal profiles, and typical cross-sections of the proposed new channel are shown on Plan Sheets
MS-1 to MS-17 (attached).

The conversion of Pond FF to a multi-cell wetland will result in no net loss of jurisdictional area.
Approximately 1.56 acres of low quality open water will be temporarily impacted. There is an
unavoidable impact of 0.007 acre to Wetland CC. This impact is the result of the installation of a new
rip-rap lined plunge pool at the pond outlet. Proposed impacts to Pond FF and Wetland CC are shown on
plan sheets SW4-1 to SW4-3 (attached)

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 current land use for the project area is wooded with adjacent residential areas with mowed lawns.
3b. List the total estimated acreage of all existing wetlands on the property:
2.38 acres (wetland) and 1.56 acres (Pond) = 3.94 acres total
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
8,504
3d. Explain the purpose of the proposed project:
The purpose of this project is to conduct stream restoration and enhancement on McAlpine Creek and two unnamed
tributaries to McAlpine Creek (Stream A and Stream B) which are also in degraded condition. The primary goals of this
stream restoration are (1) to improve water quality by reducing total suspended solids (TSS) and nutrient loading and (2)
lessen structural flooding downstream by creating more geomorphologically stable channels throughout the project area
while improving and restoring their hydrologic connection to their floodplains. In addition, the project will restore aquatic
and terrestrial habitat and enhance recreational and educational opportunities as well as provide flood water storage and
create mitigation credit. Wetland construction will also be conducted on the floodplain of McAlpine Creek with the
purpose of improving water quality. Temporary impacts to on-site jurisdictional waters are necessary to alleviate channel
erosion and enhance aquatic habitat.

Pond FF will be retrofitted as a multi-cell storm water treatment wetland. In addition to providing improved storm water
treatment this will result in improved habitat diversity and quality.

Additionally, a greenway trail is proposed for construction adjacent to McAlpine Creek. This greenway trail will extend the
existing greenway trail located to the east of Sardis Road. The proposed trail will link Providence Road to the existing
Mecklenburg County greenway trail network. There are no impacts to jurisdictional waters associated with the
construction of the greenway trail.
3e. Describe the overall project in detail, including the type of equipment to be used:
McAlpine Creek and the two unnamed tributaries to McAlpine Creek (Stream A and Stream B) will relocated to new
geomorphically stable channels. The channels will have improved channel dimensions and profiles and will exibit
improved floodplain access and sinuosity. The new channels will have in-stream structures and constructed riffles to
increase stream habitat diversity and improve channel stability. Vernal pools will be created within the McAlpine Creek
flood plain. Pond FF will be retrofitted as a multi-cell storm water treatment wetland. A trackhoe and other standard
construction equipment will be used for this project.

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 practicable. Restoration
