Charlotte, North Carolina ow
Dear Mr. Dorney:
City of Charlotte Storm Water Services (CSWS) is submitting a Pre-Construction
Notification pursuant to Water Quality Certification No. 3353. The 200 Wadsworth
Place Maintenance Project is located near uptown Charlotte, North Carolina,
approximately %2 mile northeast of the Interstate 277 (I-277) - North Tryon Street
interchange (Attachment A - Figures 1 and 2). The on-site stream channel
(Perennial Stream A) lacks sinuosity, has nearly vertical banks, and is located
between two piped drainage systems. The on-site open channel consists of 159
linear feet of failing cement-lined channel and 132 linear feet of degraded natural
channel. The purpose of this project is to stabilize the channel to facilitate adequate
conveyance of storm water flows and prevent aggradation and blockages. Proposed
activities will include performing maintenance on existing structures, installing hard
stabilization techniques, and reshaping the dimension and profile within Stream A.
On behalf of CSWS, CWS is submitting a Pre-Construction Notification application
with attachments in accordance with Water Quality Certification No. 3353
(Attachment B). Due to the limited nature of the proposed impacts, CSWS is not
proposing mitigation for this project. We are sending you seven copies of this

Existing Conditions
The 200 Wadsworth Place Maintenance Project is located near uptown Charlotte, North Carolina,
approximately %2 mile northeast of the Interstate 277 (I-277) - North Tryon Street interchange
(Attachment A - Figures 1 and 2). The purpose of this project is to stabilize and perform maintenance
on existing structures within the on-site stream channel to adequately convey storm water flows and
prevent aggradation and blockages. Carolina Wetland Services, Inc. (CWS) has been contracted by
Charlotte Storm Water Services (CSWS) to provide permitting services for this project.
Current Land Use
The project area and surrounding areas are mainly comprised of commercial and industrial land usages.
Dominant vegetation within the project area includes hackberry (Celtis laevigata), red maple
(Acer rubrum), box elder (Acer negundo), cottonwood (Populus deltoides), glossy privet
(Ligustrum lucidum), grape vine (Vitis rotundifolia), Chinese wisteria (Wisteria sinensis), Japanese
honeysuckle (Lonicera japonica), and poison ivy (Toxicodendron radicans). According to the Soil
Survey of Mecklenburg County' (Attachment A - Figure 2), soils within the project area consist of
Urban land (Ur) soils. This soil type is typically comprised of soil material that has been cut, filled, and
graded, and the natural characteristics altered or destroyed. Urban land soils are located in areas
containing greater than 85% impervious cover, resulting in a high volume of surface runoff.
Jurisdictional Delineation
On March 31, 2004, CWS's Isaac Hinson and Andrea Hughes investigated 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 Engineers Wetlands Delineation Manual' No
wetland areas were identified within the project limits. A Routine On-Site Data Form representative of
on-site non jurisdictional upland areas has been included as Attachment C. Jurisdictional waters of the
U.S. were classified according to recent North Carolina Division of Water Quality (NCDWQ)4 and
USACE guidance. A NCDWQ Stream Classification Form and USACE Stream Quality Assessment
Worksheet representative of Stream A have been included as Attachment D.

200 Wadsworth Place Maintenance Project April 22, 2004
Nationwide Permit Nos. 3 and 13 Project No. 20040618
The results of the on-site field investigation indicate that there is one jurisdictional stream channel
(Stream A) located within the project limits (Attachment A - Figure 3). Stream A is an unnamed
tributary to Little Sugar Creek, which is part of the Catawba River basin (HU# 030501035) and is
classified as "Class C" waters by the NCDWQ.
Stream A generally flows southeast through the project area between Wadsworth Place and 16'
Street (Attachment A - Figure 3). Stream A is a predominantly cement-lined channel that was
evaluated to be Perennial. This stream exhibits a five-foot bankfull width, moderate flow, and lacks
sinuosity. This channel also drains approximately 170 acres and exhibited a weak presence of
benthic macroinvertebrates (chironomid midges and caddisfly larvae) during the field investigation
(Attachment D - SCP1). Stream A scored 35, out of a possible 71 points on the NCDWQ Stream
Classification Form and 39 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet. Photographs of Stream A have been included as Attachment E - Photographs A and B.
Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (S°HPO) on April 7, 2004, to
determine the presence of any areas of architectural, historic, or archaeological significance that
would be affected by the project. To date, not response has been received from SHPO.
Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on
April 7, 2004 to determine the presence of any federally-listed species or critical habitat located
within the project area. In a letter dated April 13, 2004, the NCNHP responded that "[They have] no
record of rare species, significant natural communities, or priority natural areas at the site nor within
a mile of the project area" (Attachment F).
Purpose and Need for the Project
Perennial Stream A lacks sinuosity, has nearly vertical banks, and is located between two piped
drainage systems. The on-site open channel consists of 159 linear feet of failing cement-lined
channel and 132 linear feet of degraded natural channel. The purpose of this project is to stabilize
the channel to facilitate adequate. conveyance of storm water flows and prevent aggradation and
blockages. The channel slope is less than 1% and sediment accumulation has reduced the capacity of

the channel. The current channel condition has caused flooding of an adjacent commercial building
that resulted in the demolition of the building.
Avoidance and Minimization
This project is necessary to prevent aggradation and flooding. Activities are proposed for the entire
on-site portion of the channel. Hard stabilization is necessary to accommodate high velocity flows
that result from the lack of channel pattern and rapid runoff from adjacent highly-impervious areas.
Natural channel design was considered as an alternative for this project, but was deemed impractical
due to the close proximity of existing buildings and railroad infrastructure. Proper sediment and
erosion control measures will be implemented during construction to minimize temporary impacts to
downstream waters. Base flow will be pumped around the channel during construction and concrete
will be allowed to set before water is diverted back into the channel.
Proposed Impacts to Jurisdictional Waters
Proposed activities will include performing maintenance on existing structures, installing hard
stabilization techniques, and reshaping the dimension and profile within Stream A.. Proposed
activities under Nationwide Permit No. 3 will not result in additional impacts to jurisdictional areas
and will include the replacement of an endwall and 159 linear feet of failing concrete lining within
Stream A. Proposed impacts under Nationwide Permit No. 13 will consist of installing 132 linear
feet of concrete lining (i.e., hard stabilization) within a degraded portion of channel located between
two existing concrete-lined channel segments. The degraded portion of the channel was previously
lined with concrete, but has washed out due to the age of the pavement. In addition, all on-site
portions of Perennial Stream A will be reshaped to a more uniform profile (i.e., 1% slope) and stable
dimension (i.e., lay banks back from vertical to 1:1 slope) (Attachment G - Figures 4a-c). A
summary of the proposed activities has been provided as Table 1. On behalf of CSWS, CWS is
submitting a.Pre-Construction Notification application with attachments in accordance with Water
Quality Certification No. 3353 (Attachment B).

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
' location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score
of 100 representing a stream of the highest quality.
Total Score (from reverse): 39 Comments: Channel is currently lined with cement. Recent adjacent
development activities have resulted in extensive sedimentation of channel. A weak presence of chironomid midees and caddisflv
larvae were sampled in the channel.

Dear Mr. Hinson:
The Natural Heritage Program has no record of rare species, significant natural communities, or
priority natural areas at the site nor within a mile of the project area. Although our maps do not
show records of such natural heritage elements in the project area, it does not necessarily mean
that they are not present. It may simply mean that the area has not been surveyed. The use of
Natural Heritage Program data should not be substituted for actual field surveys, particularly if
the project area contains suitable habitat for rare species, significant natural communities, or
prioriiy natural areas.
You may wish to check the Natural Heritage Program database website at
' <www.nesparks.net/nhp/search.html> for a listing of rare plants and animals and significant
natural communities in the county and on the topographic quad map. Please do not hesitate to
contact me at 919-715-8697 if you have.questions or need further information.

Charlotte, North Carolina
Dear Mr. Domey:
City of Charlotte Storm Water Services (CSWS) is submitting a Pre-Construction
Notification pursuant to Water Quality Certification No. 3353. The 200 Wadsworth
Place Maintenance Project is located near uptown Charlotte, North Carolina,
approximately %2 mile northeast of the Interstate 277 (I-277) - North Tryon Street
interchange (Attachment A - Figures 1 and 2). The on-site stream channel
(Perennial Stream A) lacks sinuosity, has nearly vertical banks, and is located
between two piped drainage systems. The on-site open channel consists of 159
linear feet of failing cement-lined channel and 132 linear feet of degraded natural
channel. The purpose of this project is to stabilize the channel to facilitate adequate
conveyance of storm water flows and prevent aggradation and blockages. Proposed
activities will include performing maintenance on existing structures, installing hard
stabilization techniques, and reshaping the dimension and profile within Stream A.
On behalf of CSWS, CWS is submitting a Pre-Construction Notification application
with attachments in accordance with Water Quality Certification No. 3353
(Attachment B). Due to the limited nature of the proposed impacts, CSWS is not
proposing mitigation for this project. We are sending you seven copies of this

Executive Summary
The 200 Wadsworth Place Maintenance Project is located near uptown Charlotte, North Carolina,
' approximately %2 mile northeast of the Interstate 277 (I-277) - North Tryon Street interchange
(Attachment A - Figures 1 and 2). The purpose of this project is to stabilize and perform
maintenance on existing structures within the on-site stream channel to adequately convey storm
' water flows and prevent aggradation and blockages. Carolina Wetland Services, Inc. (CWS) has
been contracted by Charlotte Storm Water Services (CSWS) to provide permitting services for this
project.
' The results of the on-site field investigation conducted by CWS indicate that there is one
jurisdictional stream channel (Stream A) located within the project limits (Attachment A - Figure 3).
Proposed activities will include performing maintenance on existing structures, installing hard
' stabilization techniques, and reshaping the dimension and profile within Stream A
(Attachment G - Figures 4a-c). Additional impacts resulting from these activities will total 132 linear
feet of hard stabilization within Stream A. On behalf of CSWS, CWS is submitting a
' Pre-Construction Notification application in accordance with Water Quality Certification No. 3353
(Attachment B). Due to the limited nature of the proposed impacts, CSWS is not proposing
mitigation for this project.

Existing Conditions
The 200 Wadsworth Place Maintenance Project is located near uptown Charlotte, North Carolina,
approximately 1/2 mile northeast of the Interstate 277 (I-277) - North Tryon Street interchange
(Attachment A - Figures 1 and 2). The purpose of this project is to stabilize and perform maintenance
on existing structures within the on-site stream channel to adequately convey storm water flows and
prevent aggradation and blockages. Carolina Wetland Services, Inc. (CWS) has been contracted by
Charlotte Storm Water Services (CSWS) to provide permitting services for this project.
Current Land Use
The project area and surrounding areas are mainly comprised of commercial and industrial land usages.
Dominant vegetation within the project area includes hackberry (Celtis laevigata), red maple
(Acer rubrum), box elder (Acer negundo), cottonwood (Populus deltoides), glossy privet
(Ligustnim lucidum), grape vine (Vitis rotundifolia), Chinese wisteria (Wisteria sinensis), Japanese
honeysuckle (Lonicera japonica), and poison ivy (Toxicodendron radicans). According to the Soil
Survey of Mecklenburg County' (Attachment A - Figure 2), soils within the project area consist of
Urban land (Ur) soils. This soil type is typically comprised of soil material that has been cut, filled, and
graded, and the natural characteristics altered or destroyed. Urban land soils are located in areas
containing greater than 85% impervious cover, resulting in a high volume of surface runoff.
Jurisdictional Delineation
On March 31, 2004, CWS's Isaac Hinson and Andrea Hughes investigated on-site jurisdictional waters
of the U.S.z 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 Manuals No
wetland areas were identified within the project limits. A Routine On-Site Data Form representative of
on-site non jurisdictional upland areas has been included as Attachment C. Jurisdictional waters of the
U.S. were classified according to recent North Carolina Division of Water Quality (NCDWQ)4 and
USACE guidance. A NCDWQ Stream Classification Form and USACE Stream Quality Assessment
Worksheet representative of Stream A have been included as Attachment D.
` United States Department of Agriculture, 1980. Soil Survey of Mecklenburg County, North Carolina.

The results of the on-site field investigation indicate that there is one jurisdictional stream channel
(Stream A) located within the project limits (Attachment A - Figure 3). Stream A is an unnamed
tributary to Little Sugar Creek, which is part of the Catawba River basin (I-U# 030501035) and is
classified as "Class C" waters by the NCDWQ.
Stream A generally flows southeast through the project area between Wadsworth Place and 16'
Street (Attachment A - Figure 3). Stream A is a predominantly cement-lined channel that was
evaluated to be Perennial. This stream exhibits a five-foot bankfull width, moderate ,flow, and lacks
sinuosity. This channel also drains approximately 170 acres and exhibited a weak presence of
benthic macroinvertebrates (chironomid midges and caddisfly larvae) during the field investigation
(Attachment D - SCPl). Stream A scored 35 out of a possible 71 points on the NCDWQ Stream
Classification Form and 39 out of a possible 100 points on the USACE Stream Quality Assessment
Worksheet. Photographs of Stream A have been included as Attachment E - Photographs A and B.

Purpose and Need for the Project
Perennial Stream A lacks sinuosity, has nearly vertical banks, and is located between two piped
drainage systems. The on-site open channel consists of 159 linear feet of failing cement-lined
channel and 132 linear feet of degraded natural channel. The purpose of this project is to stabilize
the channel to facilitate adequate. conveyance of storm water flows and prevent aggradation and
blockages. The channel slope is less than I% and sediment accumulation has reduced the capacity of

Comments:
Staff visited the site on April 22, 2004. The applicant requests approval for stream maintenance and
stabilization (- 290 ft). The site is located off N. Tryon St. approximately 1/4 mi. north of 1-277. The
stream is degraded and has little to no sinuosity. Approximately 150 ft of stream channel is currently
cement lined (stream bed and bank). The remaining portion (132 ft) of the stream appears to have
been previously cement lined but over time the cement has degraded and eroded. The area
surrounding the stream segment is commercial/industrial development- Little vegetation exist excel
along the channel.

SUBJECT: Review of an application by City of Charlotte Storm Water Services, Unnamed
Tributary Little Sugar Creek, DWQ No. 040663, Mecklenburg County
The City of Charlotte is requesting 401 Water Quality Certification from the North Carolina
Division of Water Quality. The NCWRC has reviewed information provided by the applicant,
and field biologists on our staff are familiar with habitat values of the project area. These
comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C.
466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C.
661-667d).
The proposed project is to use concrete to provide stabilization for a total of 132 new stream
impacts and 159 linear feet of previously concreted stream to improve flooding conditions in the
urban area. Concrete streams do not improve water quality or aquatic habitat values.
Based on our review of the submittal, we believe that bioengineering methodologies should be
fully examined prior to issuance of permits/certifications for concreting existing or additional
stream reaches. State-of-the-art bioengineering techniques, including restoration of floodplains
and Low Impact Development (LID) retrofits upstream should be more environmentally suitable
for water quality and urban habitats. Information on LID measures can be found at
www.lowimpactdevelopment.org. Accordingly, additional stream evaluations using
bioengineering practices should be provided by project proponents. If it is practicable to improve
water quality and habitat values by bioengineering, the City should use these methodologies.
Thank you for the opportunity to review and comment on this project. If you have any questions
regarding these comments, please contact me at 336/769-9453.

the channel. The current channel condition has caused flooding of an adjacent commercial building
that resulted in the demolition of the building.
Avoidance and Minimization
This project is necessary to prevent aggradation and flooding. Activities are proposed for the entire
on-site portion of the channel. Hard stabilization is necessary to accommodate high velocity flows
that result from the lack of channel pattern and rapid runoff from adjacent highly-impervious areas.
Natural channel design was considered as an alternative for this project, but was deemed impractical
due to the close proximity of existing buildings and railroad infrastructure. Proper sediment and
erosion control measures will be implemented during construction to minimize temporary impacts to
downstream waters. Base flow will be pumped around the channel during construction and concrete
will be allowed to set before water is diverted back into the channel.
Proposed Impacts to jurisdictional Waters
Proposed activities will include performing maintenance on existing structures, installing hard
stabilization techniques, and reshaping the dimension and profile within Stream A. Proposed
activities under Nationwide wi not result in additional impacts t1 areas
;and will e the replacement of an endwall and 159 linear feet of failing conining within
eam A. Proposed impacts under Nationwide Permit No. 13 will consist of installing 132 linear
feet of concrete lining (i.e., hard stabilization) within a degraded portion of channel located between
two existing concrete-lined channel segments. The degraded portion of the channel was previously
line ith concrete, but has washed out due to the age of the pavement. In addition, all on-site/
portions of Perennial Strea ilze reshaped to a more uniform profile (i.e., 1 °/ and stable
dimension (i.e., lay banks back from vertical to 1:1 slope) (Attachment G Figures 4a-c). A
summary of the proposed activities has been provided as Table 1. On behalf of CSWS, CWS is
submitting a Pre-Construction Notification application with attachments in accordance with Water
Quality Certification No. 3353 (Attachment B).

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
' location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more
' continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score
of 100 representing a stream of the highest quality.
Total Score (from reverse): 39 . Comments: Channel "is currently lined with cement. Recent adiacent
development activities have resulted m extensive sedimentation of channel. A weak presence of chironomid midges and caddisflv
¦ larvae were sampled in the channel.

Dear Mr. Hinson:
The Natural Heritage Program has no record of rare species, significant natural communities, or
priority natural areas at the site nor within a mile of the project area. Although our maps do not
show records of such natural heritage elements in the project area, it does not necessarily mean
that they are not present. It may simply mean that the area has not been surveyed. The use of
Natural Heritage Program data should not be substituted for actual field surveys, particularly if
the project area contains suitable habitat for rare species, significant natural communities, or
priority natural areas.
You 'may wish to check the Natural Heritage Program database website at
<www.ncsparks.net/nhp/search.html> for a listing of rare plants and animals and significant
' natural communities in the county and on the topographic quad map. Please do not hesitate to
contact me at 919-715-8.697 if you have.questions or need further information.
Sincerely,
Harry E. LeGrand, Jr., Zoologist
