MEMORANDUM
TO: John R. Dorney, Division of Water Quality
Dept. of Environment and Natural Resources
FROM: Ron Linville, Regional Coordinato
Habitat Conservation Program
DATE: April 17, 2003
SUBJECT: Review of 401 Certification Application, City of Charlotte Stormwater Services,
Enfield Road/Windsor Park Capital Improvements Project, 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 City of Charlotte proposes to stabilize portions of an unnamed tributary to Briar
Creek. The project will provide roughly 1,469 linear feet of bioengineered perennial stream
stabilization and 244 linear feet of intermittent channel stabilization. Existing pipes will be
replaced. Roughly 40 linear feet of gabions will be used and 351 linear feet of rip rap will be
installed. Approximately 601 linear feet of new pipe installation will occur.
Although we prefer reducing impacts from piping and riprap on the project, we will not
object to the project since the City of Charlotte Stormwater Services appears to have avoided
impacts while stabilizing stream reaches and providing flood control. Consideration should be
given to further reductions in piping length. We recommend that deed restrictions be provided
for work accomplished on private and public property to help preserve stabilized streambanks.
This project may not be acceptable for mitigation unless durable stabilization improvements
provide significant water quality and aquatic habitat benefits.
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.

Re: Response to DWQ comments for the Enfield/Windsor Park Storm Drainage Improvement
project (Enfield Project), City of Charlotte Storm Water Services, Mecklenburg County,
North Carolina
DWQ Project 03-0138
Dear Mr. Dorney:
The City of Charlotte is providing the following responses to your comments dated 3/13/03
regarding the Enfield Project.
SITE PLAN:
1. Plans are too small to read. Please provide full size plans at a suitable scale (for
instance 1" = 1009).
CSWS reply: Seven copies of Enfield plans are enclosed at 1" = 40' scale.
2. Please show all stream impacts including all fill slopes, dissipaters, and bank
stabilization.
CSWS reply: The enclosed Enfield plans include fill slopes, dissipaters and bank stabilization
activities. Please see enclosed Enfield plans and Impact Summary Table for locations and lengths
for each project activity.
3. Please indicate exact locations of existing pipes to be replaced and indicate the location
and lengths of all new pipes and/or extensions of existing pipes.
CSWS reply: The enclosed Enfield plans indicate the exact locations of existing pipes to be replaced
and indicate the location and lengths of all new pipes and/or extensions of existing pipes. Please see
enclosed Enfield plans and Impact Summary Table for locations and lengths for each project activity.

4. Please locate the exact bank treatment on the site plan.
CSWS reply: The enclosed Enfield plans indicate the locations of the exact bank treatment areas.
Please see enclosed Enfield plans and Impact Summary Table for locations and lengths for each
project activity.
MITIGATION:
1. It is not clear that the Edsel Place stream work is adequate for mitigation credits.
Please note that credit would be awarded based on whether the project would be
considered restoration or enhancement. "Bio-engineered" channels may be considered
as stabilization only and, as such, could not be used as mitigation credit.
CSWS reply: The Edsel Place (DWQ #99-1368) stream restoration project credit (2,750 If) was
previously approved by DWQ as meeting the definition of restoration with a credit ratio of 1:1. The
Twin Lane project utilized 1,7801f of the 2,7501fof stream restoration provided by the Edsel Place
project. The Edsel Place stream restoration project provides adequate compensatory mitigation for
the minor extent (164 If) of unavoidable impacts to perennial streams associated with the upstream
Enfield CIP. CSWS will utilize 164 if of the remaining restoration credit to offset unavoidable
impacts to 1641f to perennial channel.
APPLICATION:
1. The application indicated 600 feet of "new storm pipe." It is not clear if this includes
replacement, extensions, or new culverted channel.
CSWS reply: The Impact Summary Table, Attachment C of the previously submitted permit
application indicates a total of 601 linear feet of new pipe. As indicated by Table footnotes, this
includes extensions (21 If), new pipe (580 If), and day-lighting of channel (18 if - not subtracted
from 601 total) among 8 locations. These activities occur in either perennial or intermittent
aquatically unimportant channel. Please see enclosed Enfield plans and Impact Summary Table for
locations and lengths for each project activity.
Existing pipe replacement lengths are provided in the column to the immediate left of the New Pipe
column. The total pipe replacements include 1,663 if at 7 of the locations where new pipe is also
proposed.
2. The application also calls for 164 feet of channel culverting. Please clarify and
reconcile this information preferably in a tabular format.
CSWS reply: The Impact Summary Table, Attachment C of the previously submitted permit
application indicated 1641f of new pipe length at site #14. This is the only significant section of new
pipe enclosure on a perennial channel segment. CSWS discussed this activity separately on page 11
of the PCN, because CSWS is proposing compensatory mitigation for this channel segment.

Dear Mr. Chapin:
' On behalf of the City of Charlotte Storm Water Services (CSWS), enclosed please find a completed
Pre-Construction Notification (PCN) Joint Form (Attachment A), along with accompanying request
for jurisdictional determination package (Attachment B) for Nationwide Permit (NWP) No. 3, NWP
No. 13, and NWP No. 39, for the above-referenced storm water improvements project. CSWS has
' retained Law Engineering and Environmental Services, Inc. (LAW) to provide permitting services for
this project. This submittal is the product of a cooperative effort between CSWS, LAW, and
USInfrastructure of Carolina, Inc (USI). USI is providing design/engineering services to CSWS for
' this project. An Individual Permit (IP) application dated February 5, 2003 has been previously
submitted by CSWS for the Enfield Road/Windsor Park Capital Improvements Project (CIP).
CSWS understands that the U.S. Army Corps of Engineers (USAGE) conducted a field review of
jurisdictional waters in the Enfield Road/Windsor Park CIP study area on February 18, 2003. Based
on this review effort, CSWS understands that the USACE has characterized the channel parallel to
Cheval Place as an intermittent, aquatically unimportant stream, rather than a perennial stream.
CSWS personnel conducted a subsequent field assessment of this channel on February 18, 2003, and
concur with the USACE determination, for the purposes of Section 404 permitting efforts. CSWS
E personnel also met with personnel from the North Carolina Department of Environment and Natural
Resources (NCDENR) Division of Water Quality (DWQ) at the site on February 25, 2003. DWQ
personnel confirmed the characterization of the Cheval Place channel as an intermittent, aquatically
unimportant stream, and determined that no mitigation would be required for impacts to this channel.
Small watershed extent and anecdotal landowner evidence further confirms the intermittent nature of
this channel.

Enfield Road/Windsor Park Capital Improvements Project
Section 404 Pre-Construction Notification February 28, 2003
LAW Project 30100-0-0369, Phase 04
Based on the USACE/DWQ characterization of the Cheval Place channel as intermittent and
aquatically unimportant, the proposed project will result in less than 300 linear feet (If) of
unavoidable impacts to perennial streams. It is now CSWS's understanding that a Section 404 IP will
no longer be required for the proposed project. CSWS hereby withdraws the previously-submitted IP
application for the Enfield Road/Windsor Park CIP, dated February 5, 2003. CSWS further requests
that the USACE and DWQ consider the following document as Pre-Construction Notification (PCN)
for project coverage through Nationwide Permit (NWP) Nos. 3, 13, and 39.
Proiect Overview
CSWS, in conjunction with LAW, is submitting this PCN for authorization under NWP No. 3 -
Maintenance, NWP No. 13 - Bank Stabilization, and NWP No. 39 - Residential, Commercial, and
Institutional Developments. Since the proposed project will result in over 500 if of streambank
stabilization activities, this PCN is being provided in accordance with the USACE NWP No. 13
requirements. Notification is also being made for the proposed storm pipe installation, and
resultant loss of open waters below the ordinary high water mark, in accordance with NWP No. 39
guidelines. In addition, notification is being provided to request written verification for culvert
replacement and maintenance activities under NWP No. 3.
CSWS is proposing storm drainage and conveyance improvements in the Enfield Road/Windsor
Park neighborhood, along several unnamed tributaries to Brier Creek (hereafter referred to as
"Briar Creek"). The proposed project area is located north of Central Avenue, between Briar
Creek and Sharon Amity Road, in Charlotte, North Carolina (Attachment B, Figure 1). The limits
of the project area encompass the Windsor Park neighborhood, extending from Central Avenue
northward to Sudbury Road and northwest to Eastway Drive (Attachment B, Figures 1 and 2a).
The Windsor Park neighborhood is bounded to the north by residences and the Methodist Home
for the Aged, to the east by Sharon Amity Road, to the south by residences along Central Avenue,
and to the west by residences along Kilborne Drive and Eastway Drive. Inadequacies in the local
drainage conveyance system are currently resulting in streambank erosion and the flooding of
streets, homes, and property. The proposed storm drainage improvements will involve channels
located east of Kilbome Drive, west of Sharon Amity Road, and north of Central Avenue.
Dwellings are generally located within 75 to 100 feet of the top of channel banks.
To minimize property flooding and enhance the natural benefits of the waterway, CSWS is
proposing streambank stabilization at various locations along approximately 1,469 linear feet (If)
(i.e., 2,653 bank feet [bf]') of the approximately 3,350 if of jurisdictional stream channels within
the study area, and new pipe placement within 601 If of jurisdictional stream channel. In addition,
CSWS plans to conduct minor maintenance activities, such as culvert replacements and gabion
installation (40 bf/lf), along approximately 2,054 if of channel within the study area (Attachment
B, Figure 2c). Additionally, aesthetically unpleasing debris, such as clothing, trash, and bicycles,
will be removed from stream channels within the project area. Without the proposed
improvements, erosion and pollution will continue to be a problem. Photographs of the project
area channels and impact summary tables are included in Attachments B and C, respectively. The
completion of this project should result in streambank stabilization, flood reduction, reduced
sedimentation, and improved habitat resources.
"Bank feet": distance along a single streambank (e.g., 50 linear feet of stream channel with 2 streambanks = 100 bank
feet).

Section 404 Pre-Construction Notification February 28, 2003
LAW Project 30100-0-0369, Phase 04

A detailed alternatives analysis, along with the project's purpose and need, are discussed in the
PCN Joint Form (Attachment A). In general, channel stabilization and storm pipe installation are
necessary along stream reaches that have become significantly incised or which are actively
contributing to adjacent property flooding. Whenever practical, soil bioengineering streambank
stabilization of streambanks is planned. These "soft" stabilization techniques will include
streambank grading and use of a native riparian seed mix for re-vegetation, along with coir fiber
rolls/logs and rock for toe protection. The amount of rock toe protection will vary based upon
calculated levels of shear stress, but will average one to two feet in height. Toe protection
measures will help stabilize streambanks against shear stresses that may exceed the stabilizing
influences of vegetation alone.
In addition to streambank stabilization and storm pipe installation, the proposed project will also
involve maintenance activities such as culvert maintenance/replacement at separate locations on area
stream channels, in order to reduce flooding and protect public safety (Attachment B, Figure 2c).
The proposed culvert maintenance/replacement activities are necessary to improve hydraulic
conditions and drainage conveyance beneath several roads in the project area, in order to reduce
flooding of adjacent properties and structures. The repair and/or augmentation of riprap aprons will
be necessary to satisfy erosion control standards. The culvert maintenance/replacement projects have
been designed to achieve current City of Charlotte design standards for conveyance of the 25-year
storm event. Pipe system maintenance efforts have been designed to meet design standards for
conveyance of the 10-year storm event. Riprap aprons at pipe outfalls have been designed to be the
minimum size required for energy dissipation, and to satisfy current erosion and control design
standards.
Impacts to jurisdictional waters of the U.S. will occur in accordance with the conditions of both
federal (USACE) and state (NCDENR DWQ) regulations, pursuant to Section 404 and 401 of the
Clean Water Act (CWA), respectively. Streambank stabilization activities, storm pipe installation,
and culvert maintenance/replacement efforts are proposed under USACE Nationwide Permits No.
3, 13, and 39, pursuant to the conditions of CWA Section 404. Activities affecting jurisdictional
waters of the U.S. will not begin prior to receipt of the requisite Section 404 permit and
corresponding Section 401 Water Quality Certification (WQC).
Jurisdictional Waters of the U.S.
Approximately 3,350 if of jurisdictional waters of the U.S. are located within the anticipated
construction limits (Attachment B, Figure 4). Project activities will largely be conducted within
the bed and bank of these stream channels. Possible wetland areas in the study area were
evaluated using the Routine On-Site Determination method as described in the 1987 "Corps of
Engineers Wetlands Delineation Manual" (Environmental Laboratory, 1987). This technique uses
a multi-parameter approach, which requires positive evidence of the following three criteria:
hydrophytic vegetation, wetland hydrology, and hydric soils. Field reconnaissance conducted by
LAW revealed that no wetlands are present within the proposed project construction limits.
The primary subject stream (an unnamed tributary to Briar Creek, DWQ Stream Number 11-137-8-
2) flows northwest through the project area until converging with Briar Creek. This unnamed
tributary is a perennial channel with an average width of 15 feet (measured from top of bank to top
of bank) and a channel bottom nine feet wide, with substrate composed of sand, gravel, and riprap
(Attachment B). Minor excavation within the channel improvement areas will be necessary for
Enfield Road/Windsor Park Capital Improvements Project

LAW Project 30100-0-0369, Phase 04
installation of rock toe and/or coir fiber log toe protection measures and in proximity to the
proposed culvert maintenance locations. Additional excavation may also be necessary to install
grade control structures, where needed. Overall channel geometry will largely remain unchanged.
Vegetation associated with the subject stream varies from areas bordered by maintained lawns to
natural areas with sycamore (Platanus occidentalis), mulberry (Morus rubra), red maple (Acer
rubrum), elderberry (Sambucus canadensis), jewelweed (Impatiens capensis), soft rush (Juncus
effusus), and smartweed (Polygonum pensylvanicum).
LAW scientists completed a series of stream assessments on the subject channels utilizing the
USACE Intermittent Channel Evaluation Form and DWQ Stream Classification Form on
September 15, 18, 19, and 27, 2000 (Attachment B). These stream assessments provided a means
to differentiate between non jurisdictional ephemeral channels and jurisdictional
intermittent/perennial streams. Jurisdictional intermittent streams were further categorized as
"aquatically important" or "aquatically unimportant" in accordance with USACE methodology.
Those streams categorized as perennial were considered to be aquatically important by the USACE
and met DWQ's definition of perennial (i.e., confirmed presence of fish, crayfish, or shellfish, or a
positive 7Q10/30Q2 flow). Jurisdictional areas were confined to the bed and bank of the channels.
Figure 4 in Attachment B (Approximate Waters of the U.S. Boundary Map) identifies the stream
segments assessed by LAW and the findings of those assessments. This figure also identifies
findings of the subsequent field determination made by the USACE on specific channel segments,
on September 19, 2000. Stream assessment forms are included in Attachment B.
The downstream portion of the subject stream channel, extending from Sudbury Road to its
confluence with Briar Creek (approximately 4,300 If), was previously characterized as part of the
Environmental Assessment (EA) for the Edsel Place Stream Restoration Project (State
Clearinghouse No. 1032), utilizing the "Rosgen Stream Classification Method 2,, (USInfrastructure,
2000/2001; Rosgen, 1997). Based on this analysis, the downstream portion of the subject stream
channel is characterized as a Rosgen G5c stream type with unnatural sinuosity and meander
pattern. The upstream portion was not characterized, since restoration of this portion of the
channel was not planned.
Impacts to Waters of the U.S.
Completion of the proposed project will result in impacts to jurisdictional stream channels. These
impacts will include soil bioengineering streambank stabilization (approximately 1,469 If/2,653
bf), gabion installation (approximately 40 bf/lf), and new pipe placement (approximately 601 If).
A detailed description of project impacts is included in the PCN Joint Form (Attachment A).
Proposed stabilization locations are identified in Attachment B figures, along with an impact
summary table in Attachment C.
Bank Stabilization Activities
Completion of the proposed storm drainage system improvements project will result in potential
impacts to approximately 1,469 ]f/2,653 bf (measured along centerline of the stream) of

jurisdictional stream channel resulting from streambank stabilization measures. The streambank
stabilization is proposed as follows (Attachment B, Figure 2b):
• Approximately 977 if (1,869 bf) of streambank stabilization utilizing soil
' bioengineering (with rock toe protection) on a perennial stream
• Approximately 248 if (312 bf) of streambank stabilization utilizing soil
bioengineering (with coir fiber roll toe protection) on a perennial stream
' • Approximately 244 if (472 bf) of streambank stabilization utilizing soil
bioengineering (with rock toe protection) on an intermittent, aquatically
unimportant stream
New Storm Pipe Placement
New storm pipe will be installed at a total of six locations in the project area (Attachment B,
Figures 2b and 2c). New conventional storm pipe will be installed upstream of Tamerlane Drive
(306 If, parallel to Cheval Place), and between Gladstone Lane and Birchcrest Drive (164 If).
Natural bottom arch culverts will replace the two most-downstream conventional culverts at
Sudbury Road (with three linear foot extension) and at Dunaire Road (with 18 if extension).
Placement of new pipe is also proposed along approximately 110 if of intermittent, aquatically
unimportant channel, including upstream of Darbrook Drive (79 If), and between Enfield Road and
the main channel (31 If). While the presence of existing sanitary sewer lines, culvert bends, and
long pipe lengths will prevent burial of many replacement culverts below streambed elevations,
culvert inlets and outlets have been designed to closely match existing streambed gradients.
Maintenance Activities
This project will also involve maintenance activities such as culvert and pipe system replacements
at separate locations on area stream channels, in order to address flooding problems and to protect
public safety (Attachment B, Figure 2c). A total of 351 if of riprap, 40 bf/lf of gabion, and 1,663
If of culvert/pipe system replacements will occur on area streams (Attachment C), for total
impacts of 2,054 If. The proposed culvert and pipe system replacement/maintenance activities are
necessary to improve hydraulic conditions and drainage beneath several roads in the project area,
which become flooded and eventually result in flooding of yards and structures. The culvert
replacement/maintenance projects have been designed to achieve current City of Charlotte design
standards for conveyance of the 25-year storm event. Pipe system replacement efforts have been
designed to reduce home flooding and to meet design standards for conveyance of the 10-year
storm event. Proposed supplemental riprap aprons at pipe outfalls are designed to be the minimum
size required for energy dissipation, and to satisfy current erosion and control design standards.
Compensatory Mitigation
It is not anticipated that compensatory mitigation will be required for the soil bioengineering
streambank stabilization (1,469 If) since completion of these activities is expected to result in
substantial improvements to the aquatic and riparian ecosystem. However, it is anticipated that
compensatory mitigation would be required to offset permanent losses of perennial stream channel
for the placement of new pipe at one location (164 If). As compensatory mitigation for these
impacts, CSWS proposes to utilize 164 If of mitigation credits from the Edsel Place Stream

Restoration Project (DWQ #991368/ USACE #200030332). DWQ has previously determined that
no mitigation will be required for impacts to the Cheval Place channel.
The Edsel Place project site is located immediately downstream of the Enfield Road/Windsor Park
CIP study area in an urban residential portion of eastern Charlotte. The project site consists of
approximately 2,7501f of an unnamed tributary to Briar Creek. The upstream limit of the project
site corridor is Sudbury Road. The stream in this section parallels Edsel Place on the west
(Attachment B, Figure 6). The Edsel Place watershed is approximately 0.56 square miles, and is
generally bounded by Central Avenue to the south, Sharon Amity Road to the east, Shamrock
Road to the north, and Kilborne Drive to the west. (NOTE: Twin Lane CIP previously used 1,780
If of Edsel Place mitigation length to compensate for 8901f of pipe.)
Morphological Stream Characteristics
Edsel Place morphological stream characterization data was gathered to describe the subject
project site and determine the appropriate restoration solution. These investigations included the
field identification and measurement of stream characteristics, which indicate the degree of
impairment such as slope, bank height, vegetative cover and quality of in-stream habitat. The
determination of impairment severity was based on comparisons of the impacted reach to relatively
stable reaches within the project area and reference reaches downstream of the project site. Use of
empirical data of natural stream types as a means of assessing stream condition at the project area
was determined to be an inappropriate approach because the project watershed condition is in an
unnatural or urbanized state.
Project Techniques and Goals
The primary goal of this stream restoration project was to provide/restore flood-prone zones to the
channel, and to stabilize the banks utilizing soil bioengineering techniques. Utilizing these types
of stabilization alternatives in conjunction with debris removal was the preferred alternative for
this type of project, given the nature of the existing site/watershed characteristics and constraints.
Existing portions of the stream that are stable have remained unaltered ("No-build alternative"),
which conserved resources and minimized stream disturbance. Soil bioengineering techniques
were used throughout the remainder of the Edsel Place project corridor to accomplish the
restoration objectives.
Two primary bioengineering stabilization techniques were used for the Edsel Place project. In
areas where velocities and shear forces were determined to be within acceptable ranges, and lateral
constraints were less restrictive, stream cross sectional and plan form dimensions were altered to
provide for more gradual bank slopes and a "floodplain shelf' (Figure 3). Coir fiber rolls were
used to stabilize the bank toe. Additionally, slopes were graded more gradually after
accommodating the flood shelf and were covered by coir fiber matting and live stakes. A riparian
buffer was planted with containerized trees and shrubs. The flood shelf was seeded with a riparian
grass seed mix. The proposed floodplain shelf will serve as depositional and storage areas for
sediment and fines that would normally be deposited in the channel under it's current condition.
Under the proposed condition, the in-stream habitat quality has been improved, as the deposition
of fines has been transferred to the floodplain.

LAW Project 30100-0-0369, Phase 04
Stabilizing all stream banks exclusively with this first technique was not feasible due to high and
steep banks that could not be made shallower because of lateral constraints (i.e., residential
property structures, surface streets, etc.). The lack of appropriate space, due to the proximity of
the constraints in these areas, restricted both grading, and the ability to restore natural stream
meanders in some areas. Therefore, natural meanders were restored where appropriate in areas
away from these constraints. Greater velocities and shear forces at and below bankfull stage were
compensated for in these locations. These hydraulic forces were determined to be greater at
bankfull stage than coir materials and vegetation alone could handle. In these areas, a second
bioengineering technique was utilized. This technique combined stone placed at the bank toe and
in the channel substrate with coir fiber matting and woody vegetation on the banks (Figure 4). The
use of stone was limited to the toe of the bank slopes and did not involve armoring to the top of
bank. Typical woody materials utilized throughout the project included silky dogwood (Cornus
amomum), American elder or elderberry (Sambucus canadensis), silky willow (Salix sericea), and
black willow (Salix nigra).
The application of stone/rock at or above the active channel (bankfull) elevation only occurred at
stormwater pipe outfall locations. These treatment areas served to reduce erodible velocities, as
well as provide for improved water quality treatment prior to entering the channel system.
Monitoring and Reporting
To evaluate the success of the mitigation and stream restoration efforts, CSWS has implemented a
mitigation monitoring plan that includes monitoring of geomorphic characteristics, biological-
chemical habitat characteristics, and vegetation survival. The plan covers a five year period
beginning with a pre-construction event, continuing with the in-construction year, and concluding
with three consecutive years following the year in which construction was completed.
Annual monitoring reports are now being prepared by CSWS and submitted to the USACE and
DWQ for review. Monitoring reports will continue to be submitted for a total of 4 consecutive
years (2001 - 2004). Each report focuses on the findings of that year's monitoring and includes a
cumulative account of all monitoring to date. Any corrective measures performed, or needed are
discussed, and the success of the project is summarized. Each report includes supporting
documentation, such as photographs keyed to a site plan and data forms.
Regulatory Implications
As part of its Surface Water Improvement and Management (SWIM) Program, the Mecklenburg
County Department of Environmental Protection (MCDEP) has established streamside buffers for
perennial waters throughout Mecklenburg County, to include the establishment of buffers along
Briar Creek and its tributaries. Stream buffer widths of 50 feet and 35 feet have been established
for approximately 4,900 if and 1,400 If, respectively, of Briar Creek tributaries in the proposed
project area watershed (Attachment B, Figure 5). Following project implementation, disturbed
areas will be stabilized, to comply with SWIM buffer regulations. According to October 30, 2000
SWIM buffer guidance documentation (Section III-E-h), projects characterized as "Drainage
Improvements/Repairs for Maintenance ([including] projects completed by Charlotte-Mecklenburg
Storm Water Services)" require post-construction stabilization, but not mitigation.

Protected Species
A search of the North Carolina Natural Heritage Program (NCNHP) database provided information
concerning the potential occurrence of threatened and/or endangered species within Mecklenburg
County, North Carolina (NCNHP, 2001). This database indicates that there are seven federally
and/or state threatened or endangered species which may occur in Mecklenburg County, namely the
bald eagle (Haliaeetus leucocephalus), Carolina heelsplitter (Lasmigona decorata), Georgia aster
(Aster georgianus), tall larkspur (Delphinium exaltatum), smooth coneflower (Echinacea laevigata),
Schweinitz's sunflower (Helianthus schweinitzii), and Michaux's sumac (Rhus michauxii).
LAW submitted a letter to the USFWS dated September 28, 2000 requesting comments regarding
beneficial or adverse affects of the proposed storm water improvement project, relative to the
interests of the agency (Attachment D). As of the date of this PCN, a response from the USFWS
has not been received.
In a letter dated September 29, 2000, NCNHP revealed a record of Carolina thistle (Cirsium
carolinianum), a candidate species for the State list, that is found in similar habitat as the federally
listed endangered Schweinitz's sunflower (Attachment E). The Carolina thistle is found on the
grounds of the Methodist Home, near the northern limits of the project study area.
During LAW's on-site field visits conducted on September 15, 18, 19, and 27, 2000 to identify
jurisdictional waters of the U.S. and wetlands, potential habitat for Schweinitz's sunflower,
Georgia aster, Carolina thistle, and smooth coneflower was observed, however, no individual
plants or populations were noted. An area identified as having potential habitat for protected plant
species is located within the boundaries of the Methodist Home Park. The latest available storm
drainage improvement plans do not identify this area as within the Enfield Road/Windsor Park CEP
construction limits, and it is unlikely that implementation of the proposed project will impact this
area. No habitat for these protected plant species was observed within the proposed construction
area.
The potential presence of freshwater mussels, particularly the Carolina heelsplitter (Lasmigona
decorata), was also considered during project planning efforts. Occurrences of the Carolina
heelsplitter have not been documented in the portion of the Catawba River Basin containing the
project area (USFWS, 1996). The nearest known population is located in Goose Creek (Union
County), approximately 18 miles east-southeast of the project area. Additionally, the preferred
habitat for the Carolina heelsplitter, including mud, muddy sand, or muddy gravel substrate, is not
present. The project area does not provide suitable foraging, nesting, or roosting habitat for the
bald eagle. Michaux's sumac has been likely extirpated from Mecklenburg County (USFWS,
1993) and was not observed on the subject property. The potential habitat areas suitable for
federally protected plant species are outside the proposed construction areas, and are unlikely to be
impacted by the proposed project. As a result, the proposed project is not expected to impact
federally protected species. As the project will largely be confined to the bed and bank of the
stream, the likelihood of the channel stabilization and flood control project impacting non-aquatic
protected species is remote.

Cultural Resources
LAW submitted a letter to the North Carolina Department of Cultural Resources (NCDCR), the
State Historic Preservation Office (SHPO), on September 28, 2000, requesting comments
regarding beneficial or adverse affects of the proposed storm water improvement project, relative
to the interests of the agency (Attachment F). Subsequent correspondence from NCDCR stated
that there are no known archaeological sites within the proposed project area. Based on present
knowledge of the area, NCDCR also stated that it is unlikely that any archaeological resources,
which may be eligible for inclusion in the National Register of Historic Places, will be affected by
the proposed project (Attachment F). Therefore, an archaeological investigation within the
proposed project area was not recommended. The proposed project will largely be confined within
the bed and bank of the subject stream channels. No structures will be demolished or otherwise
impacted as a result of the proposed project. The channel stabilization and flood control project is
not anticipated to result in impacts to areas of archaeological or historical value.
North Carolina Environmental Policy Act Documentation
According to a 1998 memorandum authored by Coleen Sullins (DWQ) documenting interim
stream and wetland thresholds for DWQ review under the State Environmental Policy Act (SEPA),
projects disturbing a total of greater than 5001f of perennial stream channels require SEPA review.
Since the proposed Enfield Road/Windsor Park CIP activities discussed in this NWP application
will utilize public funding and may disturb over 500 If of perennial stream channel with hard
structure, these activities exceed the SEPA review threshold and have required preparation of an
environmental assessment (EA) and corresponding SEPA review. An EA was prepared by CSWS
and LAW, reviewed by the NCDENR, and submitted to the State Clearinghouse (SCH). SCH has
assigned Project No. 1193 (and State Application Number 01-E-4300-0502) to the Enfield
Road/Windsor Park CEP during initial project scoping efforts. DWQ has assigned Project No.
13120 to the Enfield Road/Windsor Park CIP. A Finding of No Significant Impact (FONSI) was
issued by DWQ on September 13, 2002 (Attachment G).

10. Describe the purpose of the proposed work: To minimize property flooding and enhance
the natural benefits of the waterway, CSWS is proposing streambank stabilization at various
locations along approximately 1,469 If (2,653 bf) of the approximately 3,350 If of jurisdictional
stream channels within the study area, and new pipe placement within 601 If of jurisdictional
stream channel. In addition, CSWS plans to conduct minor maintenance activities, such as
culvert replacements, along approximately 2,054 If of channel within the study area
(Attachment B). Additionally, aesthetically unpleasing debris, such as clothing, trash, and
bicycles will be removed from stream channels within the project area. Without the proposed
improvements, erosion and pollution will continue to be a problem. Left in their current state,
eroding streambanks and flooding conditions will: a) jeopardize public safety by impacting
property structures and roadways and will b) perpetuate the continued degradation of the
stream environment and associated riparian habitat. The proposed project will help to satisfy
CSWS's -goal of maintaining and improving area storm water drainage systems in the interest
of local communities wildlife, and natural resources. Completion of this project will result in
positive long-term benefits to: storm water drainage, streambanks, stream channels, adjacent
properties, and habitat resources (both aquatic and terrestrial). Short-term adverse impacts
during construction should be offset by long-term benefits to the watershed.

IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
An Individual Permit OP') application (dated February 5, 2003) was previously submitted for USACE
review. Following USACE field review of study area stream channels, it was determined that the
proposed proiect should be permitted through the Nationwide Permit (NWP) program. CSWS
hereby withdraws the original IP application, and requests that the USACE consider permitting of
the proposed proiect through Nationwide Permit No. 3, NWP No. 13, and NWP No. 39.
Since the proposed Enfield Road/Windsor Park CIP activities discussed in this NWP application
will utilize public funding and may disturb over 500 If of perennial stream channel with hard
structure these activities exceed the SEPA review threshold and have required preparation of an
environmental assessment (EA) and corresponding SEPA review. An EA was prepared by CSWS
and LAW, reviewed by the NCDENR, and submitted to the State Clearinghouse (SCH). SCH
assigned Project No. 1193 (and State Application Number 01-E-4300-0502) to the Enfield
Road/Windsor Park CIP during initial proiect scoping efforts. DWO has assigned Proiect No.
13120 to the Enfield Road/Windsor Park CIP. A Finding of No Significant Impact (FONSI) was
issued by DWO on September 13, 2002 (Attachment 1).

site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Several alternatives were considered for the proposed storm drainage improvements associated
with the Enfield Road/Windsor Park CIP. To determine the appropriate methods for addressing
the existing storm drainage inadequacies resulting in streambank erosion and flooding, the
project area and existing storm drainage system were evaluated by CSWS, in cooperation with
n OL1n _-r I AIAI AU-...-..a:...,. ?.. -,.:r..-, r .... . ...a wa aL.w ?.......... nnn4 ta??......:....
detention' alternative to address the reduction of downstream flooding. Tributaries in the project
area were evaluated to determine appropriate measures for streambank erosion control methods.
Among the options considered for streambank stabilization were the use of soil bioengineering
(Rosaen Prioritv IV restoration) and the use of aabions. both in coniunction with the removal of
methods were also consicierea. A no-action
channel stabilization and flood control proiect.
The project area poses a number of challenges, including an established riparian habitat along
proximitV to the targeted culverts, pipes, and streams. in aaartion, local property owners nave
expressed concerns regarding potential loss of trees and canopy cover during storm water
improvement efforts. Considering these constraints and the necessity of the proposed
improvements. some impacts to the unnamed Briar Creek tributaries in the prolect area will be
unavoidable.
A. Partial Repair Alternative
The partial repair alternative, involving replacement of undersized culverts, was considered in
order to provide greater conveyance capacity beneath roadway crossings. This alternative could
reduce localized flooding at these crossings by increasing discharge capacity, but would do little
Page 8 of 20
to improve water quality, and would not address unstable, eroded streambanks between the
roadway crossings. This alternative was therefore eliminated from further consideration.
B. Upstream Detention Alternative
Upstream detention was considered as an alternative to potentially reduce downstream flooding
and erosion. To achieve significant peak flow attenuation in the project area, a large detention
facility, constructed on the main stream segment, or multiple smaller basins constructed in
headwater areas, would be required. A large, on-line facility was ruled out as an option for the
' following reasons: 1) based on existing topography, there are no significant, upstream floodplain
storage areas along the main stream or its primary tributaries; and 2) the stream corridors and
their floodplains are generally fully developed.
In evaluatina possible headwater detention sites, only one undeveloped site with favorable
topography was identified. The site is approximately 3.5 acres in extent and is located upstream
of Auburndale Road. The drainage area to this site is less than five percent of the total watershed
' area to the proiect area, therefore significant peak flow attenuation cannot be achieved by
detention at this site alone. For this reason, and because no other suitable detention sites could
be identified within this generally, fully developed watershed, upstream detention was determined
to be unfeasible for this proiect.
C. No-Action Alternative
A no-action alternative was also considered Tor the proiect.. AS aiscussea earlier, IT improvements
are not made within the Windsor Park area drainage system, continued flooding of neighborhood
streets, crawlspaces, basements, and yards would occur. Additionally, existing channel erosion
will continue and exacerbate sedimentation and clopping of stream culverts. Ultimately, this
alternative would result in the threat of structural damage, and public health and safety concerns
with continued flooding of low elevation areas. After evaluating conditions of the decaying
roadway, culverts/pipes, and eroding streambanks, the no-action alternative was eliminated from
further consideration since it is not consistent with the proiect purpose and need, and would fail
to solve existing storm drainage problems. The no-action alternative would allow existing stream
conditions to continue to degrade in the proiect area leading to further bank erosion, downstream
sedimentation, private property loss, and public safety risk.
D. Alternatives for Streambank Stabilization
Prioritv I. 11, and III restoration alternatives (Rosgen, 1997) were concluded not to be feasible due
to urban constraints, including the close proximity of utilities, homes, and other structures to
channels in the proiect area. Priority I restoration typically re-establishes a channel on the
previous floodplain. In urban settings where structures are located within the former floodplain,
Priority I restoration is not feasible because it would result in flood damage to existing urban
development or would require the relocation of existing structures. Priority II restoration typically
involves re-establishment of the floodplain at or above the existing original flood elevation. If
Priority II restoration were implemented, a new channel would be excavated within the existing
bed and the existing bed would be utilized as a floodplain. The resulting increased sheer stress
and velocities would require the upper banks to be sloped and stabilized to reduce erosion durinq
flood events. Priority II restoration is not feasible as a new channel cannot be excavated in the
existing narrow bed because residences are located within 75 feet of the top of the channel bank.
Priority III restoration also typically requires the channel to be excavated to achieve the desired
dimension, patterns, and profile. Additionally, Priority III restoration sometimes requires widening
of the channel. Widening the channel would be limited by the close proximity of residences. Due
' primarily to urban constraints, Priority IV restoration (soil bioengineering) was concluded to be
the recommended alternative for the proposed channel stabilization and flood control proiect.
Page 9 of 20
In addition, stabilizing streambanks exclusively with riprap was considered. This alternative is
not desirable due to impacts to stream habitat. As noted in the January 2001 Planning Study and
Report prepared by USI, riprap streambank stabilization may satisfy the mechanical needs of the
barren banks, installation results in short-term impacts to stream habitat, including the
suppression of vegetation in the streambank.
E. Alternatives for New Pipe Placement
Substantial deepening and widening of the existing channels at four locations in the project area
was considered as an alternative to new pipe placement. However, the existing channels and
floodplains in these areas have been severely encroached upon over the past 30 to 40 years by
private property, including residences, fences, and storage sheds. Sloping and stabilization of
the banks are not possible due to the close proximity of private property. Additionally, these
channel segments fall between existing pipe systems, further making deepening and widening of
the channels impractical due to engineering constraints.
RECOMMENDED ALTERNATIVES/PROPOSED PROJECT ACTIVITIES
A. Streambank Stabilization
using a combination of these techniques was determined to provide a feasible alternative for the
channel stabilization and flood control project. It is anticipated that soil bioengineering will be
used where the exclusive use of vegetation is a feasible option (i.e., where the streambank is
shallow and slopes are gradual). Restoring and improving the streambank corridor with
vegetation will improve habitat resources, will shade the stream (reducing water temperature), will
proceed to the downstream proiect limit. Equipment will be operated from the top of the bank,
rather than the streambed, in order to minimize potential construction impacts.
Stabilization of the eroding streambanks is proposed utilizing a Rosgen Priority IV restoration
approach. Priority IV restoration is typically implemented where urban constraints limit
restoration alternatives. Priority IV stabilization methods are used to decrease bed and
streambank erosion, often through the use of gabions and bioengineering methods. The land
needed for such improvements is minimal, additionally making Priority IV restoration appropriate
for the proposed project as urban constraints (i.e., close proximity of residences) serve as the
primary restricting factor for other alternatives.
Soil bioengineerinq is a relatively un-intrusive, low-impact technique that utilizes plants to re-
establish natural streambank protection that has been damaged or lost. Soil bioengineering will
be used in areas that provide adequate room for appropriate bank slope, and will encompass
soil bioengineering. The soil bioengineering techniques to be utilized for this project will consist
Page 10 of 20

to armor approximately the bottom two feet of the streambank. This rock toe protection will vary
based upon calculated levels of shear stress. The riprap will provide protection against shear
stresses exceeding the capabilities of soil bioengineering techniques. Plantings will be inspected
after the first growing season (late summer/early fall) and, if necessary at the beginning of the
second growing season The bioengineering contractor will be responsible for replacement of
non-viable plantings after the above-mentioned inspections, to achieve the -goal of 80 percent
survival of live stakes.
While soil bioengineering is generally the most desirable streambank stabilization method with
regards to aquatic and wildlife habitat, the use of vegetation to stabilize the entire length of the
streambank is not feasible due to the proximity of residences and steep vertical banks located
along the project corridor.
In addition streambank stabilization utilizing soil bioengineering will be implemented at two
specific locations (between Enfield Road and the main channel, and at Darbrook Drive), involving
a total of 244 If (472 bf) of intermittent, aquatically unimportant stream. While new storm pipe
placement was initially considered for this channel, streambank stabilization was eventually
selected in order to maintain an open channel and reduce impacts.
B. Placement of New Storm Pipe
New storm pipe placement is proposed at six specific locations within the project area for a total
of 185 If in perennial streams and 416 If in intermittent, aquatically unimportant streams. The
placement of new storm pipe was deemed necessary in order to create a hydraulically efficient
system upstream of Tamerlane Drive as well as between Birchcrest and Gladstone Drive. The
short stream segment upstream of Tamerlane Drive falls between a downstream pipe system
(approximately 570 feet long) and an upstream pipe system (completely enclosed). The existing
channel is shallow, and due to the pipe systems located on either side, engineering studies have
concluded that this channel segment is contributing to the hydraulically inefficient system,
resulting in yard and crawlspace flooding. As previously noted, widening and deepening this
channel is not a practicable solution since this would require encroachment on private property,
and would impact nearby structures. However, an efficient system can be created with the
placement of 36-inch reinforced concrete pipe (RCP) at this location. This would require limited
alteration of the surrounding topography. Placement of new storm pipe upstream of Tamerlane
Drive will result in impacts to two segments of intermittent stream channel, totaling 306 If.
The placement of new storm pipe on a stream segment located between Birchcrest and Gladstone
Drive is needed for essentially the same reasons as stated above for the Tamerlane Drive stream
segment. The existing channel and floodplain have been severely encroached upon by residential
development with structures approximately 40 years old. This stream channel also falls between
two pipe systems and is contributing to the inefficient overall system. The placement of a new 36-
inch RCP in the existing channel will result in impacts to approximately 164 If of perennial stream
channel but should alleviate yard and crawlspace flooding in the project area.
Two natural bottom three-sided arch culverts will replace the downstream-most existing
conventional culverts (beneath Sudbury Road and Dunaire Drive). The natural bottom culvert
beneath Sudbury Road will require a three linear foot extension, while the natural bottom culvert
beneath Dunaire Drive will require an 18 If extension. Two additional culvert system replacements
will result in new storm pipe lengths shorter than the existing system lengths. The new Birchcrest
Drive culvert will be approximate ten linear feet shorter than the existing culvert, while the new
Page l 1 of 20
primarily of live staking and fascine installation. The plant materials generally used for this type
work are silky willow (Salix sericea) silky dogwood (Corpus amomum), elderberry (Sambucus
canadensis) Virginia willow Utea virginica), and coralberry (Symphoricarpos orbiculatus). Other
Larkspur Lane culvert will be approximately eight linear feet shorter than the existing culvert .
These reduced lengths are the product of culvert realignment only, however, and will not result in
any new channel "daylighting."
A minor pipe extension between Enfield Road and the main channel is needed to save a private
shed located adjacent to the channel. Without this pipe extension, the homeowner's shed would
be impacted by other channel improvements upstream. Placement of this new 36-inch RCP will
result in impacts to approximately 31 If of intermittent, aquatically unimportant stream channel.
Placement of new pipe upstream of Darbrook Drive is necessary in order to create a hydraulically
efficient system. The existing channel is comprised of grouted riprap lining and the channel and
floodplain have been severely encroached upon by historic residential development. Additionally,
the channel is located between the Darbrook Drive culvert and a completely enclosed upstream
pipe system. The placement of new 42-inch RCP in the existing channel will result in impacts to
approximately 79 If of intermittent, aquatically unimportant stream channel.
C. Maintenance Activities
Culvert maintenance activities, including associated riprap inlet/outlet protection placement, will
be performed in jurisdictional channels at eight existing roadway crossing locations, and will
increase conveyance capacity to minimize/eliminate "bottlenecks" at existing undersized culverts.
The new culverts will address these "bottlenecks" by lowering upstream water surface elevations
during storm water discharge events while minimizing street and structural flooding. These
maintenance efforts will include: 1) approximately 1,663 If of storm pipe replacement (1,502 If
along perennial channel and 161 If along intermittent, aquatically unimportant channel); 2)
approximately 40 bf/If of gabion installation (along perennial channel); and 3) approximately 351 If
of riprap replacement for inlet/outlet protection (291 If along perennial stream channel and 60 If
along intermittent, aquatically unimportant stream channel),
assoc
Drive). These natural bottom culverts, consisting of aluminum arch culverts on concrete strip
footings, will provide greater environmental benefits than direct in-kind replacement of box
culverts. Natural bottom culverts have non-structural bottoms that allow for the restoration of a
natural streambed. The natural bottom culverts will improve conditions of the streams by
providing enhanced aquatic habitat, in comparison to conventional box culverts. The remaining
culvert/pipe system replacements will largely involve direct in-kind replacement. A number of
these culverts include bends, sanitary sewer crossings, and drainage structures. In certain
instances the culvert inlet and outlet elevations match the proposed stream elevations and cannot
be buried due to the presence of sewer lines that cross beneath the pipe system.
Gabions proposed for this protect are rock-filled baskets or capes, and are used to build support
or an abutment where erosion poses a threat, such as loss of property. This technique offers
sturdy support and enforcement and is feasible in that it meets the mechanical needs of the
channel. Gabions can be utilized in areas where space is limited, such as in urban neighborhoods
where dwellings are located close to the stream channel, and have been targeted to replace failing
retaining walls. Gabions are necessary on a short, 40 bf/If segment of perennial stream, since re-
sloping of the bank is not possible due to the close proximity of single-family dwellings. The
property is near the top of bank and there is not enough room for a 2:1 slope. The use of gabions
on this vertical bank will provide protection for the streambank and the adjacent structure. While
the use of gabions provides a solution to the eroding streambank problem, installation may result
in short-term impacts to stream habitat, including the suppression of existing vegetation in the
streambank.
Page 12 of 20
Culvert maintenance construction activities will generally begin at the downstream project limit
and will proceed to the upstream project limit, so that increased stream flow volume resulting
from pipe upsizing is accommodated However, minor variations may occur to accommodate
construction schedules, easement acquisitions, and property owner requests. Streambank
stabilization measures will typically progress from upstream to downstream. Construction access
and activities will take place from the top of the bank, and construction vehicles will not be driven
into the stream. There should be no adverse impacts to the stream's hydrologic or hydraulic
performance as a result of the proposed storm drainage improvements.
Summary
A combination of storm water management measures was determined to be the preferred
alternative for the proposed CIP. These storm drainage improvement measures include: 1)
approximately 1,469 If (2,653 bf) of soil bioengineering streambank stabilization (1,225 If (2,181 bfl
along perennial channel and 244 If [472 bfl along intermittent, aquatically unimportant channel); 2)
approximately 1,663 If of storm pipe replacement (1,502 If along perennial channel and 161 If along
intermittent aquatically unimportant channel); 3) approximately 40 bf/If of gabion installation
(along perennial channel); 4) approximately 351 If of riprap placement (291 If along perennial
stream channel and 60 If along intermittent, aquatically unimportant stream channel), at four inlets
and seven outlets, with aprons ranging in length from 20 feet to 55 feet; and 5) approximately 601
If of new storm pipe installation.
Soil bioengineering streambank stabilization was selected on the basis of its low environmental
impact and habitat benefits. Gabion utilization has been limited to a single location, where this
approach should produce few impacts and will increase streambank stability. New storm pipe
extent has been minimized to the maximum extent practicable, and will include replacement of
two conventional culverts with natural bottom arched culverts. Following project completion,
CSWS will monitor stability and success of the proposed measures.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.htmi.
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
It is not anticipated that compensatory mitigation will be required for the soil bioengineering
streambank stabilization (1,469 If) since completion of these activities is expected to result in
substantial improvements to the aquatic and riparian ecosystem. However, it is anticipated that
compensatory mitigation would be required to offset permanent losses of perennial stream
channel for the placement of new pipe at one location (164 If). As compensatory mitigation for
these impacts, CSWS proposes to utilize 164 If of mitigation credits from the Edsel Place Stream
Restoration Project (DWO #991368/ USACE #200030332).
The Edsel Place project site is located immediately downstream of the Enfield CIP study area in an
urban residential portion of eastern Charlotte. The project site consists of approximately 2,750 If
of an unnamed tributary to Briar Creek. The upstream limit of the proiect site corridor is Sudbury
Road. The stream in this section parallels Edsel Place on the west (Attachment B. Figure 6). The
Edsel Place watershed is approximately 0.56 square miles, and is generally bounded by Central
Avenue to the south, Sharon Amity Road to the east, Shamrock Road to the north, and Kilborne
Drive to the west. (NOTE: Twin Lane CIP previously used 1,780 If of Edsel Place mitigation length
to compensate for 890 If of pipe.)

r
Morphological Stream Characteristics
Edsel Place morphological stream characterization data was gathered to describe the subject
project site and determine the appropriate restoration solution. These investigations included the
field identification and measurement of stream characteristics, which indicate the degree of
r impairment such as slope bank height vegetative cover and quality of in-stream habitat. The
determination of impairment severity was based on comparisons of the impacted reach to
relatively stable reaches within the project area and reference reaches downstream of the project
' site Use of empirical data of natural stream types as a means of assessing stream condition at
the project area was determined to be an inappropriate approach because the protect watershed
condition is in an unnatural or urbanized state.
Project Techniques and Goals
The primary goal of this stream restoration project was to provide/restore flood-prone zones to
the channel and to stabilize the banks utilizing soil bioengineering techniques. Utilizing these
types of stabilization alternatives in conjunction with debris removal was the preferred alternative
for this type of project, given the nature of the existing site/watershed characteristics and
constraints.
Existing portions of the stream that are stable have remained unaltered ("No-build alternative"),
which conserved resources and minimized stream disturbance. Soil bioengineering techniques
were used throughout the remainder of the Edsel Place proiect corridor to accomplish the
t restoration objectives.
Two Primary bioenqineerinq stabilization techniques were used for the Edsel Place project. In
areas where velocities and shear forces were determined to be within acceptable ranges, and
t lateral constraints were less restrictive stream cross sectional and plan form dimensions were
altered to provide for more gradual bank slopes and a "floodplain shelf" (Figure 3). Coir fiber rolls
were used to stabilize the bank toe. Additionally, slopes were graded more gradually after
t accommodating the flood shelf and were covered by coir fiber matting and live stakes. A riparian
buffer was planted with containerized trees and shrubs. The flood shelf was seeded with a
riparian grass seed mix The proposed floodplain shelf will serve as depositional and storage
areas for sediment and fines that would normally be deposited in the channel under it's current
condition Under the proposed condition the in-stream habitat quality has been improved, as the
deposition of fines has been transferred to the floodplain.
' Stabilizing all stream banks exclusively with this first technique was not feasible due to high and
steep banks that could not be made shallower because of lateral constraints (i.e., residential
property structures surface streets etc.). The lack of appropriate space, due to the proximity of
the constraints in these areas restricted both grading, and the ability to restore natural stream
meanders in some areas. Therefore natural meanders were restored where appropriate in areas
away from these constraints. Greater velocities and shear forces at and below bankfull stage
were compensated for in these locations. These hydraulic forces were determined to be greater at
bankfull stage than coir materials and vegetation alone could handle. In these areas, a second
bioengineering technique was utilized. This technique combined stone placed at the bank toe and
in the channel substrate with coir fiber matting and woody vegetation on the banks (Figure 4).
The use of stone was limited to the toe of the bank slopes and did not involve armoring to the top
of bank Typical woody materials utilized throughout the project included silky dogwood (Cornus
amomum) American elder or elderberry (Sambucus canadensis), silky willow (Salix sericea , and
' black willow (Salix nigra).
The application of stone/rock at or above the active channel (bankfull) elevation only occurred at
stormwater pipe outfall locations. These treatment areas served to reduce erodible velocities, as
r well as provide for improved water quality treatment prior to entering the channel system.

Monitorinq and Reporting

To evaluate the success of the mitigation and stream restoration efforts, CSWS has implemented
a mitigation monitoring plan that includes monitoring of geomorphic characteristics, biological=
with three consecutive years following the year in which construction was completed.
Annual monitoring reports are now being prepared by CSWS and submitted to the USACE and
DWO for review. Monitoring reports will continue to be submitted for a total of four consecutive '
years (2001 - 2004). Each report focuses on the findings of that year's monitoring and includes a
cumulative account of all monitoring to date. Any corrective measures performed, or needed are
discussed, and the success of the proiect is summarized. Each report includes supportinq
documentation, such as photographs keyed to a site plan and data forms.

' 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
' you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide
r the following information:
Amount of stream mitigation requested (linear feet): N/A
t Amount of buffer mitigation requested (square feet): N/A
Amount of Riparian wetland mitigation requested (acres): N/A
' Amount of Non-riparian wetland mitigation requested (acres): N/A
Amount of Coastal wetland mitigation requested (acres): N/A
IX. Environmental Documentation (DWQ Only)
Does the project involve an expenditure of public funds or the use of public (federal/state/local)
' land?
Yes ® No ?
If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Yes ® No ?
If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a
copy of the NEPA or SEPA final approval letter.
Yes ® No ?
' X. Proposed Impacts on Riparian and Watershed Buffers (DWQ Only)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify Mecklenburg County
Surface Water Improvement and Management (SWIM) buffers will be temporarily_ impacted -1w the
proposed project. The proposed project will incorporate vegetative stabilization of disturbed
Page 17 of 20
areas. Storm-water management projects in Charlotte are exempt from SWIM buffer mitigation
requirements. )?
Yes ? No ® If you answered "yes", provide the following information:
Identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer
mitigation is required calculate the required amount of mitigation by applying the buffer
multipliers.
Zone* Impact
(square feet)
Multiplier Required

1 0 3 0
2 0 1.5 0
Total 0 0
* Zone 1 extends out 30 teet perpendicular trom near bank of channel; Gone 2 extends an
additional 20 feet from the edge of Zone 1.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
N/A
XI. Stormwater (DWQ Only)
Describe impervious acreage (both existing and proposed) versus total acreage on the site.
Discuss stormwater controls proposed in order to protect surface waters and wetlands
downstream from the property.
No increase in existing impervious area should result from the proposed project.
XII. Sewage Disposal (DWQ Only)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
N/A

Dear Mr. Cantrell:
FIL E
The City of Charlotte Storm Water Services (CSWS) has retained Law Engineering and Environmental
' Services, Inc. (LAW) to provide environmental services for the above-identified storm drainage
improvement project. In order that LAW may fully evaluate and consider any potential effects of the
project, we are hereby requesting that you respond in writing concerning any beneficial or adverse
' impacts relative to the interests of your agency. The project vicinity and location are presented on the
attached Figure 1.
' As indicated on Figure 1, the proposed project area is located north of Central Avenue between Brier
Creek and Sharon Amity Lane. The limits of the project extend from approximately 500 feet north of
Central Avenue north to Sudbury Road 'and northwest to Eastway Drive. Waters of the U.S. located
within the proposed project area include an unnamed tributary to Brier Creek. The project area is
primarily comprised of residential development, and proposed project activities include storm drainage
improvements. As such, project activities associated with these improvements may involve culvert
placement and replacement, streambank stabilization and/or restoration of the unnamed tributary to Brier
' Creek and associated channels. It is anticipated that proposed channel improvements will largely occur
within the bed and bank of the existing channels. An estimated 6300 linear feet of stream channel may be
impacted by the project. The USGS Topographic Map that covers the project area is Charlotte East,
North Carolina.

Dear Mr. Iagnocco:
1 Thank you for your letter of September 28, 2000, concerning the above project. The northern
section (Phase 1) of the subject project was received previously from the Clearinghouse as an
Environmental Assessment in May 2000. This appears to be a southern extension to that same
project (Phase 4). The EA correctly stated on page 12 that no archaeological sites are recorded
in the proposed project area. No archaeological survey was recommended at that time.
' There are no known archaeological sites within the proposed project area. Based on our present
knowledge of the area, it is unlikely that any archaeological resources, which may be eligible for
inclusion in the National Register of Historic Places, will be affected by the project construction.
We recommend that no archaeological investigation be conducted in connection with project.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act
' and the Advisory Council on Historic Preservation's Regulations for Compliance with Section
106 codified at 36 CFR Part 800.
' Thank you for your cooperation and consideration. If you have questions concerning the above
comment, contact Renee Gledhill-Earley, Environmental Review Coordinator, at 919/7334763.

Division of Water Quality, Water.Quality Section
.,:;.Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-1, er
an environmental assessment (EA) has been prepared for stormwater conveyance improvements
involving streambank stabilization to address stream channel erosion and flooding in the City of
:Charlotte. The proposed improvements are within the Briar Creek watershed, encompassing the Enfield
?Road/Windsor Park neighborhood. The project includes streambank stabilization at various locations
along approximately 2,653 bank feet (bf) of the approximately 3,350 linear feet (If) of stream channels,
new stormwater pipe placement within 601 If of stream, and minor maintenance activities along 2.405 if
• of stream. a
Stormwater conveyance improvements are proposed for an unnamed tributary to Briar Creek and several
unnamed stream channels. Several alternatives and the no-action alternative were considered for the
,,proposed project. Three primary alternatives included (1) a partial repair involving only replacement of
undersized culverts, (2) an upstream detention facility, and (3) streambank stabilization and new storm
pipe placement. Upstream detention is not feasible due to a lack of suitable detention sites within this
fully developed urban area. Alternative (3) is the preferred alternative because it would address
continuing flooding problems and stream channel erosion in the project area. Under alternative (3),
various methods of streambank stabilization were considered including Priority I-IV (Rosgcn) restoration.
'Priority IV restoration using bioengineering, gabions, and rock toe protection was chosen and is often
..`,implemented where urban constraints limit alternatives. Soil bioengineering will consist of live staking
d .fascine installation using native species to reestablish natural streambank protection that has been
damaged or lost. In areas of high shear stress, rock toe protection will be used in combination with soil
:bioengineering measures. For the new pipe placement, channel modification was also considered and
determined to be unfeasible due to the close proximity to private residences and engineering constraints.
The proposed project area is located north of Central Avenue between Briar Creek and Sharon Amity
,Road in Charlotte. The limits of the project, encompassing the Windsor Park neighborhood, extend from
:north of Central Avenue northward to Sudbury Road and northwest to Eastway Drive. Located in the
lower Catawba River Basin in Mecklenburg County, the watershed contributing to the unnamed tributary
-to Briar Creek is approximately 378 acres. Land use is predominately single-family residential and zoned
,:to allow four units per acre.
;The length of stream to be impacted by channel stabilization with rock toe protection totals 2,181 bf.
'Minimal, temporary impacts to aquatic habitat are expected to occur, however, the project is expected to
.,have a net benefit on aquatic resources and habitat over the long term. Minor maintenance activities
including culvert replacements will have minimal impacts.

' Gabion stream stabilization will impact 40 bf of stream. There will be 601 if of piping impacts. As a
condition of the 401 Water Quality Certification for this project, it is anticipated that compensatory
' mitigation will be required to offset permanent losses of perennial stream channel for impacts associated
with the placement of pipe (491 If) and gabions (40 bf). The applicants propose to use mitigation credits
from the Hope Park Branch Stream Restoration Project.
' Potential impacts to streams will be minimized through implementation and maintenance of a State-
approved erosion and sedimentation control plan and adherence to conditions of the 401 Water Quality
Certification. Any buffer areas disturbed as a result of the proposed project will be stabilized and
' reseeded with emphasis on reforesting stream banks. Long-term water quality is expected to improve
through a reduction in streambank erosion and sedimentation.
' Land use changes are not anticipated to result from the project. The project area is a fully developed,
urban neighborhood. Changes to drainage patterns are not anticipated and no wetlands have been
identified within the proposed project limits.
Many of the proposed stabilization reaches are currently protected from development by Mecklenburg
County's Surface Water and Management riparian buffer ordinance. Naturally vegetated buffers, ranging
' in width from 35 feet to 100 feet depending on the size of the drainage basin, are protected. These buffers
will help protect the proposed stream stabilization project and stream channels from stormwater impacts.
The Division of Water Quality has concluded that the proposed project will not result in significant
' impacts to the environment. This decision is based upon information provided in the EA and review by
governmental agencies. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the
issuance of a 401 Water Quality Certification by the Division of Water Quality. An environmental
' impact statement will not be prepared for this project. This FONSI completes the environmental review
record, which is available for inspection at the State Clearinghouse.

Enclosed. Dlease find seven conies of the Pre-Construction Notification (PCN) for the Charlotte Storm Water Services (CSWS) Enfield
Road/Windsor Park Capital Improvements Project (CIP). On February 7, 2003, an Individual Permit (IP) application for this project
(dated 2/5/03) was submitted to the Division of Water Quality (DWQ), along with a check for payment of the required DWQ permit
review fee (check no. 214742). After consulting with DWQ personnel (Mr. Mike Parker) and U.S. Army Corps of Engineers
personnel (Mr. Steve Chapin), it was determined that the proposed project should be permitted with a Nationwide Permit, rather than
an IP. CSWS now wishes to withdraw the original IP application. As requested by DWQ, CSWS is now submitting the enclosed Pre-
Construction Notification for Nationwide Permit Nos. 3, 13, and 39. It is CSWS's understanding that the DWQ permit review fee for
this project has been paid by the $475.00 check submitted with the previous IP application. Should you have any questions, please
-)ntact Ms. Mary C. Murray at [phone]. We look forward to hearing from you. Thanks, and have a great day!

SUBJECT: Review of an Individual Permit Application by City of Charlotte Storm
Water Services CSWS), Enfield Road/Windsor Park Capital
Improvements Project (CFP), DWQ No, 030138, Mecklenburg County
CSWS is requesting a letter of concurrence from the North Carolina Wildlife
Resources Commission (NCWRC) to obtain a 404 permit from the I I.S. Army Corps of
Engineers. The NCWRC has reviewed information provided by the applicant, and field
biologists on our staff are familiar with habitat values of the project area. 'T'hese
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).
CSWS proposes storm drainage and conveyance improvements in the Fnfield
Road/Windsor Park neighborhood along several tributaries of Brier Creek (aka Briar
Creek). Streambank erosion and flooding concerns are issues that will be resolved by the
project. Streambank stabilization is proposed for 1469 linear feet of stream. New pipes
will be located within 601 linear feet of stream channel plus pipe maintenance and gabion
placement (40 feet). Bioengineering techniques, including coin fiber logs, rock toe
protection, streambank grading and. native plantings will be used to complete the project.
CSWS proposes to use 531 linear feet of mitigation credits from the Hope Park Branch
Stream Restoration project to offset stream impacts to perennial stream reaches in the
proposed Cl P.
Based on the information provided by the applicant and our knowledge of the
project area, we do not believe this project will cause significant negative effects to

waters. 'T'herefore, we do not object to the project. After reviewing the project plans, we
recommend the following:
1. Where possible, permanent conservation easements or deed restrictions should be
provided to preserve and protect the 35' and 50' buffers. These areas should be
restored and left undisturbed to the maximum extent practicable to provide
enhanced stabilization, shade and improved aquatic and terrestrial habitats.
2. Culverts lengths should be minimized to the extent practicable.
3. Culverts 48" or larger should be sized large enough to be buried l' into the
streambed. Culverts less than 48 inches in diameter should be buried to a depth
equal to or greater than 20% their size to allow for aquatic life passage. These
measurements must be based on natural thalweg depths.
4. Any riprap or rock used around the stream must not interfere with aquatic life
passage during low flows. Natural channel dimensions, including thalwegs
should be provided.
5. Stringent erosion control measures should be installed where soil is disturbed and
maintained until project completion.
6. l Leavy equipment should be operated from the bank rather than in the stream
channel in order to minimize sedimentation and reduce the likelihood of
introducing other pollutants into the stream.
7. Only native plant species should be used for the restoration activities.
8. 11' any concrete will be used, work must be accomplished so that wet concrete
does not contact stream water. This will lessen the chance of altering the stream's
water chemistry and causing a fish kill.

Dear Mr. Chapin:

On behalf of the City of Charlotte Storm Water Services (CSWS), enclosed please find a
' completed ENG Form 4345 and supplemental information (Attachment A) with accompanying
figures (Attachment B) for a Department of the Army Section 404 Individual Permit (IP) in the
above-referenced matter. CSWS has retained Law Engineering and Environmental Services, Inc.
' (LAW) to provide wetlands and permitting services for this project. This submittal is the product
of a cooperative effort between CSWS, LAW, and USlnfrastructure of Carolina, Inc (USI). USI is
providing design/engineering services to CSWS for this project.
' Proiect Overview
CSWS is proposing stonn drainage and conveyance improvements in the Enfield Road/Windsor
' Park neighborhood, along several unnamed tributaries to Brier Creek (hereafter referred to as
"Briar Creek"). The proposed project area is located north of Central Avenue, between Briar
Creek and Sharon Amity Road, in Charlotte, North Carolina (Attachment B, Figure 1). The limits
' of the project area encompass the Windsor Park neighborhood, extending from Central Avenue
northward to Sudbury Road and northwest to Eastway Drive (Attachment B, Figures 1 and 2a).
The Windsor Park neighborhood is bounded to the north by residences and the Methodist Home
' for the Aged, to the east by Sharon Amity Road, to the south by residences along Central Avenue,
and to the west by residences along Kilborne Drive and Eastway Drive. Inadequacies in the local
drainage conveyance system are currently resulting in streambank erosion and the flooding of
streets, homes, and property. The proposed storm drainage improvements will involve channels
located east of Kilbome Drive, west of Sharon Amity Road, and north of Central Avenue.
Dwellings are generally located within 75 to 100 feet of the top of channel banks.

(i.e., 2,653 bank feet [bf]') of the approximately 3,350 if of jurisdictional stream channels within
the study area, and new pipe placement within 601 If of jurisdictional stream channel. In addition,
CSWS plans to conduct minor maintenance activities, such as culvert replacements and gabion
installation (40 bf/lf), along approximately 2,054 if of channel within the study area (Attachment
B, Figure 2c). Additionally; aesthetically unpleasing debris, such as clothing, trash, and bicycles, .
will be removed from stream channels within the project area. Without the proposed
improvements, erosion and pollution will continue to be a problem. Photographs of the project
area channels and impact summary tables are included in Attachments C and D, respectively. The
completion of this project should result in streambank stabilization, flood reduction, reduced
sedimentation, and improved habitat resources.
A detailed alternatives analysis, along with the project's purpose and need, are discussed in the IP
Supplemental Information (Attachment A). In general, channel stabilization and storm pipe
installation are necessary along stream reaches that have become significantly incised or which are
actively contributing to adjacent property flooding. Whenever practical, soil bioengineering
streambank stabilization of streambanks is planned. These "soft" stabilization techniques will
include streambank grading and use of a native riparian seed mix for re-vegetation, along with coir
fiber rolls/logs and rock for toe protection. The amount of rock toe protection will vary based
upon calculated levels of shear stress, but will average one to two feet in height. Toe protection
measures will help stabilize streambanks against shear stresses that may exceed the stabilizing
influences of vegetation alone.
In addition to streambank stabilization and storm pipe installation, the proposed project will also
involve maintenance activities such as culvert maintenance/replacement at separate locations on area
stream channels, in order to reduce flooding and protect public safety (Attachment B, Figure 2c).
The proposed culvert maintenance/replacement activities are necessary to improve hydraulic
conditions and drainage conveyance beneath several roads in the project area, in order to reduce
flooding of adjacent properties and structures. The repair and/or augmentation of riprap aprons will
be necessary to satisfy erosion control standards. The culvert maintenance/replacement projects have
been designed to achieve current City of Charlotte design standards for conveyance of the 25-year
storm event. Pipe system maintenance efforts have been designed to meet design standards for
conveyance of the 10-year storm event. Riprap aprons at pipe outfalls have been designed to be the
minimum size required for energy dissipation, and to satisfy current erosion and control design
standards.
Impacts to jurisdictional waters of the U.S. will occur in accordance with the conditions of both
federal (U.S. Army Corps of Engineers [USACE]) and state (N.C. Department of Environment and
Natural Resources [NCDENR] Division of Water Quality [DWQ]) regulations, pursuant to Section
404 and 401 of the Clean Water Act (CWA), respectively. Streambank stabilization activities,
storm pipe installation, and culvert maintenance/replacement efforts are proposed under a USACE
IP, pursuant to the conditions of CWA Section 404, since the proposed impacts exceed those
thresholds in the USACE Nationwide Permit (NWT) Program. Activities affecting jurisdictional
waters of the U.S. will not begin prior to receipt of the requisite Section 404 permit and
corresponding Section 401 Water Quality Certification (WQC).

feet).

jurisdictional Waters of the U.S.
Approximately 3,350 if of jurisdictional waters of the U.S. are located within the anticipated
construction limits (Attachment B, Figure 4). Project activities will largely be conducted within
the bed and bank of these stream channels. Possible wetland areas in the study area were
evaluated using the Routine On-Site Determination method as described in the 1987 "Corps of
Engineers Wetlands Delineation Manual" (Environmental Laboratory, 1987). This technique uses
a multi-parameter approach, which requires positive evidence of the following three criteria:
hydrophytic vegetation, wetland hydrology, and hydric soils. Field reconnaissance conducted by
LAW revealed that no wetlands are present within the proposed project construction limits.
The primary subject stream (an unnamed tributary to Briar Creek, DWQ Stream Number 11-137-8-
2) flows northwest through the project area until converging with Briar Creek. This unnamed
tributary is a perennial channel with an average width of 15 feet (measured from top of bank to top
of bank) and a channel bottom nine feet wide, with substrate composed of sand, gravel, and riprap
(Attachment Q. Minor excavation within the channel improvement areas will be necessary for
installation of rock toe and/or coir fiber log toe protection measures and in proximity to the
proposed culvert maintenance locations. Additional excavation may also be necessary to install
grade control structures, where needed. Overall channel geometry will largely remain unchanged.
Vegetation associated with the subject stream varies from areas bordered by maintained lawns to
natural areas with sycamore (Platanus occidentalis), mulberry (Morus rubra), red maple (Acer
rubrum), elderberry (Sambucus canadensis), jewelweed (Impatiens capensis), soft rush (Juncus
effusus), and smartweed (Polygonum pensylvanicum).
LAW scientists completed a series of stream assessments on the subject channels utilizing the
USACE Intermittent Channel Evaluation Form and DWQ Stream Classification Form on
September 15, 18, 19, and 27, 2000 (Attachment E). These stream assessments provided a means
to differentiate between non jurisdictional ephemeral channels and jurisdictional
intermittent/perennial streams. Jurisdictional intermittent streams were further categorized as
"aquatically important" or "aquatically unimportant" in accordance with USACE methodology.
Those streams categorized as perennial were considered to be aquatically important by the USACE
and met DWQ's definition of perennial (i.e., confirmed presence of fish, crayfish, or shellfish, or a
positive 7Q10/30Q2 flow). Jurisdictional areas were confined to the bed and bank of the channels.
Figure 4 in Attachment B (Approximate Waters of the U.S. Boundary Map) identifies the stream
' segments assessed by LAW and the findings of those assessments. This figure also identifies
findings of the subsequent field determination made by the USACE on specific channel segments,
on September 19, 2000. Stream assessment forms are included in Attachment E.
The downstream portion of the subject stream channel, extending from Sudbury Road to its
confluence with Briar Creek (approximately 4,300 If), was previously characterized as part of the
Environmental Assessment (EA) for the Edsel Place Stream Restoration Project (State
Clearinghouse No. 1032), utilizing the "Rosgen Stream Classification Method 2,, (USInfrastructure,
2000/2001; Rosgen, 1997). Based on this analysis, the downstream portion of the subject stream
channel is characterized as a Rosgen G5c stream type with unnatural sinuosity and meander

pattern. The upstream portion was not characterized, since restoration of this portion of the
channel was not planned.
Impacts to Waters of the U.S.
Completion of the proposed project will result in impacts to jurisdictional stream channels. These
impacts will include soil bioengineering streambank stabilization (approximately 1,469 If/2,653
bf), gabion installation (approximately 40 bf/lf), and new pipe placement (approximately 601 If).
A detailed description of project impacts is included in the IP Supplemental Information
(Attachment A). Proposed stabilization locations are identified in Attachment B figures, along
with an impact summary table in Attachment D.
Bank Stabilization Activities
Completion of the proposed storm drainage system improvements project will result in potential
impacts to approximately 1,469 If/2,653 bf (measured along centerline of the stream) of
jurisdictional stream channel resulting from streambank stabilization measures. The streambank
stabilization is proposed as follows (Attachment B, Figure 2b):
Approximately 977 If (1,869 bf) of streambank stabilization utilizing soil
bioengineering (with rock toe protection) on a perennial stream
Approximately 248 if (312 bf) of streambank stabilization utilizing soil
bioengineering (with coir fiber roll toe protection) on a perennial stream
Approximately 244 if (472 bf) of streambank stabilization utilizing soil
bioengineering (with rock toe protection) on an intermittent, aquatically
unimportant stream
New Storm Pipe Placement
New storm pipe will be installed at a total of six locations in the project area (Attachment B,
Figures 2b and 2c). New conventional storm pipe will be installed upstream of Tamerlane Drive
(306 If, parallel to Cheval Place), and between Gladstone Lane and Birchcrest Drive (164 If).
Natural bottom arch culverts will replace two conventional culverts at Sudbury Road (with three
linear foot extension) and at Dunaire Road (with 18 if extension). Placement of new pipe is also
proposed along approximately 110 If of intermittent, aquatically unimportant channel, including
upstream of Darbrook Drive (791f), and between Enfield Road and the main channel (31 If).
Maintenance Activities
This project will also involve maintenance activities such as culvert and pipe system replacements
at separate locations on area stream channels, in order to address flooding problems and to protect
public safety (Attachment B, Figure 2c). A total of 351 If of riprap, 40 bf/lf of gabion, and 1,663
If of culvert/pipe system replacements will occur on area streams (Attachment D), for total
impacts of 2,054 If. The proposed culvert and pipe system replacement/maintenance activities are
necessary to improve hydraulic conditions and drainage beneath several roads in the project area,
which become flooded and eventually result in flooding of yards and structures. The culvert
rep] acement/maintenance projects have been designed to achieve current City of Charlotte design
standards for conveyance of the 25-year storm event. Pipe system replacement efforts have been

designed to reduce home flooding and to meet design standards for conveyance of the 10-year
' storm event. Proposed supplemental riprap aprons at pipe outfalls are designed to be the minimum
size required for energy dissipation, and to satisfy current erosion and control design standards.
Compensatory Mitigation
It is not anticipated that compensatory mitigation will be required for the soil bioengineered
t streambank stabilization along perennial channels (2,181 bf) since completion of these activities is
expected to result in substantial improvements to the aquatic and riparian ecosystem. However, it
is anticipated that compensatory mitigation would be required to offset permanent losses of ?
' perennial stream channel for the use of gabions (40 bf/If), and the placement of new pipe (491 10,
totaling 531 If. As compensatory mitigation for these impacts, CSWS proposes to utilize 531 if of
mitigation credits from the Hope Park Branch Stream Restoration project (USACE Action ID No.
' 200130492). The Hope Park Branch project involved approximately 3,661 if of restored channel
on Hope Park Branch (Attachment B). Prior to restoration, this channel was an important,
perennial stream with low sinuosity, moderate incision, poor in-stream habitat structure, and
erosion to bedrock (in some locations). The restored channel was designed to be consistent with
' DWQ's definition of stream restoration, as established in the May 10, 2000 "Interim, Internal
DWQ Policies on Stream Mitigation Options and Associated Macrobenthos Monitoring." The
restoration involved: 1) formation of a stable channel with appropriate dimension, pattern and
' profile; 2) reconnection of the channel to the floodplain by bed elevation adjustment; 3) placement
of natural material, such as root wads and rock vanes in the stream to improve stability and
enhance aquatic habitat; and 4) stabilization of stream banks with herbaceous and woody
' vegetation to improve aquatic habitat. The restoration plan was approved by the USACE on
March 13, 2001 and was implemented in the summer of 2002. CSWS has previously utilized
1,760 if of Hope Park's available 3,661 if of credit on separate CSWS projects (Kendall and
rojects)

' Regulatory Implications
As part of its Surface Water Improvement and Management (SWIM) Program, the Mecklenburg
County Department of Environmental Protection (MCDEP) has established streamside buffers for
perennial waters throughout Mecklenburg County, to include the establishment of buffers along
Briar Creek and its tributaries. Stream buffer widths of 50 feet and 35 feet have been established
for approximately 4,900 if and 1,400 If, respectively, of Briar Creek tributaries in the proposed
' project area watershed (Attachment B, Figure 5). Following project implementation, disturbed
areas will be stabilized, to comply with SWIM buffer regulations. According to October 30, 2000
SWIM buffer guidance documentation (Section III-E-h), projects characterized as "Drainage
Improvements/Repairs for Maintenance ([including] projects completed by Charlotte-Mecklenburg
Storm Water Services)" require post-construction stabilization, but not mitigation.
' Protected Species
A search of the North Carolina Natural Heritage Program (NCNHP) database provided information
' concerning the potential occurrence of threatened and/or endangered species within Mecklenburg
County, North Carolina (NCNHP, 2001). This database indicates that there are seven federally
and/or state threatened or endangered species which may occur in Mecklenburg County, namely the
' bald eagle (Haliaeetus leucocephalus), Carolina heelsplitter (Lasmigona decorata), Georgia aster

(Aster georgianus), tall larkspur (Delphinium exaltatum), smooth coneflower (Echinacea laevigata),
Schweinitz's sunflower (Helianthus schweinitzii), and Michaux's sumac (Rhus michauxii).
LAW submitted a letter to the USFWS dated September 28, 2000 requesting comments regarding
beneficial or adverse affects of the proposed storm water improvement project, relative to the
interests of the agency (Attachment F). As of the date of this IP application, a response from the
USFWS has not been received.
In a letter dated September 29, 2000, NCNHP revealed a record of Carolina thistle (Cirsium
carolinianum), a candidate species for the State list, that is found in similar habitat as the federally
listed endangered Schweinitz's sunflower (Attachment G). The Carolina thistle is found on the
grounds of the Methodist Home, near the northern limits of the project study area.
During LAW's on-site field visits conducted on September 15, 18, 19, and 27, 2000 to identify
jurisdictional waters of the U.S. and wetlands, potential habitat for Schweinitz's sunflower,
Georgia aster, Carolina thistle, and smooth coneflower was observed, however, no individual
plants or populations were noted. An area identified as having potential habitat for protected plant
species is located within the boundaries of the Methodist Home Park. The latest available storm
drainage improvement plans do not identify this area as within the Enfield Road/Windsor Park CIP
construction limits, and it is unlikely that implementation of the proposed project will impact this
area. No habitat for these protected plant species was observed within the proposed construction
area.
The potential presence of freshwater mussels, particularly the Carolina heelsplitter (Lasmigona
decorata), was also considered during project planning efforts. Occurrences of the Carolina
heelsplitter have not been documented in the portion of the Catawba River Basin containing the
project area (USFWS, 1996). The nearest known population is located in Goose Creek (Union
County), approximately 18 miles east-southeast of the project area. Additionally, the preferred
habitat for the Carolina heelsplitter, including mud, muddy sand, or muddy gravel substrate, is not
present. The project area does not provide suitable foraging, nesting, or roosting habitat for the
bald eagle. Michaux's sumac has been likely extirpated from Mecklenburg County (USFWS,
1993) and was not observed on the subject property. The potential habitat areas suitable for
federally protected plant species are outside the proposed construction areas, and are unlikely to be
impacted by the proposed project. As a result, the proposed project is not expected to impact
federally protected species. As the project will largely be confined to the bed and bank of the
stream, the likelihood of the channel stabilization and flood control project impacting non-aquatic
protected species is remote.
Cultural Resources
LAW submitted a letter to the North Carolina Department of Cultural Resources (NCDCR), the
State Historic Preservation Office (SHPO), on September 28, 2000, requesting comments
regarding beneficial or adverse affects of the proposed storm water improvement project, relative
to the interests of the agency (Attachment H). Subsequent correspondence from NCDCR stated
that there are no known archaeological sites within the proposed project area. Based on present
knowledge of the area, NCDCR also stated that it is unlikely that any archaeological resources,
which may be eligible for inclusion in the National Register of Historic Places, will be affected by
the proposed project (Attachment H). Therefore, an archaeological investigation within the.

proposed project area was not recommended. The proposed project will largely be confined within
' the bed and bank of the subject stream channels. No structures will be demolished or otherwise
impacted as a result of the proposed project. The channel stabilization and flood control project is
' not anticipated to result in impacts to areas of archaeological or historical value.
North Carolina Environmental Policy Act Documentation
' According to a 1998 memorandum authored by Coleen Sullins (DWQ) documenting interim
stream and wetland thresholds for DWQ review under the State Environmental Policy Act (SEPA),
projects disturbing a total of greater than 500 if of perennial stream channels require SEPA review.
' Since the proposed Enfield Road/Windsor Park CIP activities discussed in this IP application will
utilize public funding and may disturb over 5001f of perennial stream channel with hard structure,
these activities exceed the SEPA review threshold and have required preparation of an
' environmental assessment (EA) and corresponding SEPA review. An EA was prepared by CSWS
and LAW, reviewed by the NCDENR, and submitted to the State Clearinghouse (SCH). SCH has
assigned Project No. 1193 (and State Application Number 01-E-4300-0502) to the Enfield
Road/Windsor Park CEP during initial project scoping efforts. DWQ has assigned Project No.
13120 to the Enfield Road/Windsor Park CIP. A Finding of No Significant Impact (FONSI) was
issued by DWQ on September 13, 2002 (Attachment I).

SUPPLEMENTAL INFORMATION
' ENG FORM 4345
' Block 18. Nature of Activity
I. Project Description
' The City of Charlotte Storm Water Services (CSWS) is proposing storm drainage and conveyance
improvement measures for the Enfield Road/Windsor Park neighborhood, along several unnamed
tributaries to Brier Creek (hereafter referred to as "Briar Creek"). The proposed project area is located in
' Charlotte, North Carolina, north of Central Avenue and between Briar Creek and Sharon Amity Road.
Inadequacies in the local drainage system are currently resulting in streambank erosion and the flooding
of streets, homes, and property. The proposed storm drainage improvements will involve channels
' located east of Kilborne Drive, west of Sharon Amity Road and Sudbury Road, and north of Central
Avenue.
To minimize property flooding and enhance the natural benefits of the waterway, CSWS is proposing
streambank stabilization at various locations along approximately 1,469 linear feet (If) (2,653 bank feet
[bf]') of the approximately 3,3501f of jurisdictional stream channels within the study area, and new pipe
placement within 601 If of jurisdictional stream channel. Streambank stabilization efforts will include 40
bfAf of gabion installation. In addition, CSWS plans to conduct minor maintenance activities, such as
culvert replacements, along approximately 2,054 If of channel within the study area (Attachment B,
Figure 2c). Additionally, aesthetically unpleasing debris, such as clothing, trash, and bicycles, will be
removed from stream channels within the project area. Without the proposed improvements, erosion and
pollution will continue to be a problem. Photographs of the project area channels and an impact summary
table are included in Attachments C and D, respectively. The completion of this project should result in
streambank stabilization, flood reduction, reduced sedimentation, and improved habitat resources.
The proposed storm drainage and conveyance improvements within the Windsor Park neighborhood will
involve channels located east of Kilborne Drive, west of Sharon Amity Road, and north of Central
Avenue.
A. Streambank Stabilization Activities
Completion of the proposed storm drainage system improvements project will result in potential
impacts to approximately 1,469 If/2,653 bf (measured along centerline of the stream) of
' jurisdictional stream channel resulting from streambank stabilization measures. The streambank
stabilization is proposed as follows (Attachment B, Figure 2b):
' • Approximately 977 if (1,869 bf) of streambank stabilization utilizing soil
bioengineering (with rock toe protection, as required by shear stress calculations) on
a perennial stream
' • Approximately 248 If (312 bf) of streambank stabilization utilizing soil
bioengineering (with coir fiber roll toe protection) on a perennial stream
• Approximately 244 if (472 bf) of streambank stabilization utilizing soil
' bioengineering (with rock toe protection, as required by shear stress calculations) on
an intermittent, aquatically unimportant stream
1 66 Bank feet": distance along a single streambank (e.g., 50 linear feet of stream channel with 2 streambanks = 100 bank feet).
Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application
LAW Project 30100-0-0369, Phase 04
B. New Storm Pipe Installation
February 5, 2003
New storm pipe will be installed at a total of six locations in the project area (Attachment B,
Figures 2b and 2c). The placement of new pipe/culvert within 491 if of perennial stream will be
conducted at four locations, including: 1) upstream of Tamerlane Drive (3061f, parallel to Cheval
Place), 2) between Gladstone Lane and Birchcrest Drive (164 If), 3) at Sudbury Road (three if
natural-bottom culvert extension), and 4) at Dunaire Drive (18 If natural-bottom culvert
extension). Placement. of new pipe is also being proposed along intermittent, aquatically
unimportant channel, including upstream of Darbrook Drive (79 If), and between Enfield Road
and the main channel (31 If).
C. Maintenance Activities
This project will also involve maintenance activities such as culvert and pipe system
replacements at separate locations on area stream channels, in order to address flooding problems
and to protect public safety (Attachment B, Figure 2c). A total of 702 If of riprap (20-55 if
aprons), 40 bf/lf of gabion, and 1,663 if of culvert/pipe system replacements will occur on area
streams (Attachment D). The proposed culvert and pipe system replacement/maintenance
activities are necessary to improve hydraulic conditions and drainage beneath several roads in the
project area, which become flooded and eventually result in flooding of yards and structures. The
culvert replacement/maintenance projects have been designed to achieve current City of Charlotte
design standards for conveyance of the 25-year storm event. Pipe system replacement efforts
have been designed to reduce home flooding and to meet design standards for conveyance of the
10-year storm event. Proposed supplemental riprap aprons at pipe outfalls are designed to be the
minimum size required for energy dissipation, and to satisfy current erosion and control design
standards.
H. Alternatives Analysis
Several alternatives were considered for the proposed storm drainage improvements associated with the
Enfield Road/Windsor Park CIP. To determine the appropriate methods for addressing the existing storm
drainage inadequacies resulting in streambank erosion and flooding, the project area and existing storm
drainage system were evaluated by CSWS, in cooperation with USInfrastructure (USI) and LAW.
Alternatives considered as part of the January 2001 "Planning Study and Report" for the Enfield
Road/Windsor Park CIP, prepared by USI, included a `partial repair' alternative to address only
undersized culverts and pipe systems, and an `upstream detention' alternative to address the reduction of
downstream flooding. Tributaries in the project area were evaluated to determine appropriate measures
for streambank erosion control methods. Among the options considered for streambank stabilization were
the use of soil bioengineering (Rosgen Priority IV restoration) and the use of gabions, both in conjunction
with the removal of urban debris from the subject stream (Rosgen, 1997). Rosgen Priority I, II, and III
restoration methods were also considered. A no-action alternative was also considered for the proposed
channel stabilization and flood control project.
The project area poses a number of challenges, including an established riparian habitat along some
stream reaches, steep vertical streambanks throughout the project area, as well as urban constraints,
particularly the proximity of residences, utilities, and other structures in close proximity to the targeted
culverts, pipes, and streams. In addition, local property owners have expressed concerns regarding
potential loss of trees and canopy cover during storm water improvement efforts. Considering these
constraints and the necessity of the proposed improvements, some impacts to the unnamed Briar Creek
tributaries in the project area will be unavoidable.

A. Partial Repair Alternative

u
The partial repair alternative, involving replacement of undersized culverts, was considered in
order to provide greater conveyance capacity beneath roadway crossings. This alternative could
reduce localized flooding at these crossings by increasing discharge capacity, but would do little
to improve water quality, and would not address unstable, eroded streambanks between the
roadway crossings. This alternative was therefore eliminated from further consideration.
B. Upstream Detention Alternative
Upstream detention was considered as an alternative to potentially reduce downstream flooding
and erosion. To achieve significant peak flow attenuation in the project area, a large detention
facility, constructed on the main stream segment, or multiple smaller basins constructed in
headwater areas, would be required. A large, on-line facility was ruled out as an option for the
following reasons:
¦ Based on existing topography, there are no significant, upstream floodplain storage areas
along the main stream or its primary tributaries; and
¦ The stream corridors and their floodplains are generally fully developed.
In evaluating possible headwater detention sites, only one undeveloped site with favorable
topography was identified. The site is approximately 3.5 acres in extent and is located upstream
of Auburndale Road. The drainage area to this site is less than five percent of the total watershed
area to the project area, therefore significant peak flow attenuation cannot be achieved by
detention at this site alone. For this reason, and because no other suitable detention sites could be
identified within this generally, fully developed watershed, upstream detention was determined to
be unfeasible for this project.
¦ C. No-Action Alternative
t A no-action alternative was also considered for the project. As discussed earlier, if improvements
are not made within the Windsor Park area drainage system, continued flooding of neighborhood
streets, crawlspaces, basements, and yards would occur. Additionally, existing channel erosion
will continue and exacerbate sedimentation and clogging of stream culverts. Ultimately, this
alternative would result in the threat of structural damage, and public health and safety concerns
with continued flooding of low elevation areas. After evaluating conditions of the decaying
roadway, culverts/pipes, and eroding streambanks, the no-action alternative was eliminated from
' further consideration since it is not consistent with the project purpose and need, and would fail to
solve existing storm drainage problems. The no-action alternative would allow existing stream
conditions to continue to degrade in the project area leading to further bank erosion, downstream
' sedimentation, private property loss, and public safety risk.
D. Alternatives for Streambank Stabilization
' Priority I, H, and III restoration alternatives (Rosgen, 1997) were concluded not to be feasible due
to urban constraints, including the close proximity of utilities, homes, and other structures to
' channels in the project area. Priority I restoration typically re-establishes a channel on the
previous floodplain. In urban settings where structures are located within the former floodplain,
Priority I restoration is not feasible because it would result in flood damage to existing urban
' development or would require the relocation of existing structures. Priority H restoration
? 3
Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application
LAW Project 30100-0-0369, Phase 04
February 5, 2003
typically involves re-establishment of the floodplain at or above the existing original flood
elevation. If Priority II restoration were implemented, a new channel would be excavated within
the existing bed and the existing bed would be utilized as a floodplain. The resulting increased
sheer stress and velocities would require the upper banks to be sloped and stabilized to reduce
erosion during flood events. Priority II restoration is not feasible as a new channel cannot be
excavated in the existing narrow bed because residences are located within 75 feet of the top of
the channel bank. Priority III restoration also typically requires the channel to be excavated to
achieve the desired dimension, patterns, and profile. Additionally, Priority III restoration
sometimes requires widening of the channel. Widening the channel would be limited by the close
proximity of residences. Due primarily to urban constraints, Priority IV restoration (soil
bioengineering) was concluded to be the recommended alternative for the proposed channel
stabilization and flood control project.
In addition, stabilizing streambanks exclusively with riprap was considered. This alternative is
not desirable due to impacts to stream habitat. As noted in the January 2001 Planning Study and
Report prepared by USI, riprap streambank stabilization may satisfy the mechanical needs of the
channel, but could contribute to the detriment of the stream's ecological potential and therefore
conflict with project goals for improved water quality. While the use of riprap provides a
solution to the eroding streambank problem, and will provide enhanced habitat in comparison to
eroding barren banks, installation results in short-term impacts to stream habitat, including the
suppression of vegetation in the streambank.
E. Alternatives for New Pipe Placement
Substantial deepening and widening of the existing channels at four locations in the project area
was considered as an alternative to new pipe placement. However, the existing channels and
floodplains in these areas have been severely encroached upon over the past 30 to 40 years by
private property, including residences, fences, and storage sheds. Sloping and stabilization of the
banks are not possible due to the close proximity of private property. Additionally, these channel
segments fall between existing pipe systems, further making deepening and widening of the
channels impractical due to engineering constraints.
III. Recommended Alternatives/Proposed Project Activities
The preferred alternative for the Enfield Road/Windsor Park CIP involves a combination of streambank
stabilization utilizing Priority IV restoration methods (Rosgen, 1997), to include natural bioengineering
methods, gabions, riprap, and new storm pipe installation (Attachment D).
A. Streambank Stabilization
While each method of streambank stabilization provides positive benefits, neither the exclusive
use of natural soil bioengineering (with toe protection), the exclusive use of riprap streambank
stabilization, nor the exclusive use of gabions was determined to be a feasible option. However,
using a combination of these techniques was determined to provide a feasible alternative for the
channel stabilization and flood control project. It is anticipated that soil bioengineering will be
used where the exclusive use of vegetation is a feasible option (i.e., where the streambank is
shallow and slopes are gradual). Restoring and improving the streambank corridor with
vegetation will improve habitat resources, will shade the stream (reducing water temperature),
will increase the availability of coarse particulate organic matter (CPOM), and will provide
aesthetic benefit. Typical construction details of proposed bioengineering techniques are
4
Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application
LAW Project 30100-0-0369, Phase 04
February 5, 2003
illustrated in Attachment D (Sheet 1). Stabilization activities will begin at the upstream project
limit and will proceed to the downstream project limit. Equipment will be operated from the top
of the bank, rather than the streambed, in order to minimize potential construction impacts.
' Stabilization of the eroding streambanks is proposed utilizing a Rosgen Priority IV restoration
approach. Priority IV restoration is typically implemented where urban constraints limit
restoration alternatives. Priority IV stabilization methods are used to decrease bed and
streambank erosion, often through the use of gabions and bioengineering methods. The land
' needed for such improvements is minimal, additionally making Priority IV restoration appropriate
for the proposed project as urban constraints (i.e., close proximity of residences) serve as the
primary restricting factor for other alternatives.
Soil bioengineering is a relatively un-intrusive, low-impact technique that utilizes plants to re-
establish natural streambank protection that has been damaged or lost. Soil bioengineering will
be used in areas that provide adequate room for appropriate bank slope, and will encompass
approximately 1,225 if (2,181 bf) of perennial stream channel and approximately 244 if (472 bf)
of intermittent, unimportant stream channel (Attachment D). Final bank slopes will generally
average 2:1. This will minimize the amount of space needed and maximize the use of soil
bioengineering. The soil bioengineering techniques to be utilized for this project will consist
primarily of live staking and fascine installation. The plant materials generally used for this type
work are silky willow (Salix sericea), silky dogwood (Cornus amomum), elderberry (Sambucus
canadensis), Virginia willow (Itea virginica), and coralberry (Symphoricarpos orbiculatus).
Other key elements will include installation of coir fiber rolls/logs (248 If/312 bf), placement of
natural fiber erosion control matting, and seeding of flood shelves (and meander bends) with a
native riparian seed mix. Along approximately 9771f (1,869 bf) of perennial channel, riprap will
be used to armor approximately the bottom two feet of the streambank. This rock toe protection
will vary based upon calculated levels of shear stress. The riprap will provide protection against
shear stresses exceeding the capabilities of soil bioengineering techniques. Plantings will be
inspected after the first growing season (late summer/early fall) and, if necessary at the beginning
of the second growing season. The bioengineering contractor will be responsible for replacement
of non-viable plantings after the above-mentioned inspections, to achieve the goal of 80 percent
survival of live stakes.
While soil bioengineering is generally the most desirable streambank stabilization method with
regards to aquatic and wildlife habitat, the use of vegetation to stabilize the entire length of the
streambank is not feasible due to the proximity of residences and steep vertical banks located
along the project corridor.
In addition, streambank stabilization utilizing soil bioengineering will be implemented at two
specific locations (between Enfield Road and the main channel, and at Darbrook Drive),
involving a total of 244 if (472 bf) of intermittent, aquatically unimportant stream. While new
storm pipe placement was initially considered for this channel, streambank stabilization was
eventually selected, in order to maintain an open channel and reduce impacts.
B. Placement of New Storm Pipe
New storm pipe placement is proposed at six specific locations within the project area, for a total
of 491 if in perennial stream channels and 110 if in intermittent, aquatically unimportant
channels. The placement of new storm pipe was deemed necessary in order to create a
hydraulically efficient system upstream of Tamerlane Drive as well as between Birchcrest and
Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application
LAW Project 30100-0-0369, Phase 04
February 5, 2003
Gladstone Drive. The short stream segment upstream of Tamerlane Drive falls between a
downstream pipe system (approximately 570 feet long) and an upstream pipe system (completely
enclosed). The existing channel is shallow, and due to the pipe systems located on either side,
engineering studies have concluded that this channel segment is contributing to the hydraulically
inefficient system, resulting in yard and crawlspace flooding. As previously noted, widening and
deepening this channel is not a practicable solution since this would require encroachment on
private property, and would impact nearby structures. However, an efficient system can be
created with the placement of 36-inch reinforced concrete pipe (RCP) at this location. This
would require limited alteration of the surrounding topography. Placement of new storm pipe
upstream of Tamerlane Drive will result in impacts to two segments of perennial stream channel,
totaling 3061f.
The placement of new storm pipe on a stream segment located between Birchcrest and Gladstone
Drive is needed for essentially the same reasons as stated above for the Tamerlane Drive stream
segment. The existing channel and floodplain have been severely encroached upon by residential
development, with structures approximately 40 years old. This stream channel also falls between
two pipe systems and is contributing to the inefficient overall system. The placement of a new
36-inch RCP in the existing channel will result in impacts to approximately 164 if of perennial
stream channel, but should alleviate yard and crawlspace flooding in the project area.
Two natural bottom, three sided arch culverts will replace existing conventional culverts beneath
Sudbury Road and Dunaire Drive. The natural bottom culvert beneath Sudbury Road will require
a three linear foot extension, while the natural bottom culvert beneath Dunaire Drive will require
an 18 if extension. Two additional culvert system replacements will result in new storm pipe
lengths shorter than the existing system lengths. The new Birchcrest Drive culvert will be
approximate ten linear feet shorter than the existing culvert, while the new Larkspur Lane culvert
will be approximately eight linear feet shorter than the existing culvert. These reduced lengths
are the product of culvert realignment only, however, and will not result in any new channel
"daylighting."
A minor pipe extension between Enfield Road and the main channel is needed to save a private
shed located adjacent to the channel. Without this pipe extension, the homeowner's shed would
be impacted by other channel improvements upstream. Placement of this new 36-inch RCP will
result in impacts to approximately 31 if of intermittent, aquatically unimportant stream channel.
Placement of new pipe upstream of Darbrook Drive is necessary in order to create a hydraulically
efficient system. The existing channel is comprised of grouted riprap lining and the channel and
floodplain have been severely encroached upon by historic residential development.
Additionally, the channel is located between the Darbrook Drive culvert and a completely
enclosed upstream pipe system. The placement of new 42-inch RCP in the existing channel will
result in impacts to approximately 79 if of intermittent, aquatically unimportant stream channel.
C. Maintenance Activities
Culvert maintenance activities, including associated riprap inlet/outlet protection placement, will
be performed in jurisdictional channels at eight existing roadway crossing locations, and will
increase conveyance capacity to minimize/eliminate "bottlenecks" at existing undersized culverts.
The new culverts will address these "bottlenecks" by lowering upstream water surface elevations
during storm water discharge events while minimizing street and structural flooding. These
maintenance efforts will include:
6
' Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application February 5, 2003
' LAW Project 30100-0-0369, Phase 04
' 1) Approximately 1,663 if of storm pipe replacement (1,502 If along perennial channel and 161
If along intermittent, aquatically unimportant channel),
2) Approximately 40 bf/If of gabion installation (along perennial channel), and
' 3) Approximately 351 If of riprap replacement for inlet/outlet protection (291 if along perennial
stream channel and 60 If along intermittent, aquatically unimportant stream channel).
In order to minimize potential impacts associated with culvert maintenance and replacement
' activities, two replacement culverts on perennial streams will utilize natural bottom (three-sided)
designs, rather than implementing direct in-kind replacement (at Sudbury Road and Dunaire
Drive). These natural bottom culverts, consisting of aluminum arch culverts on concrete strip
' footings, will provide greater environmental benefits than direct in-kind replacement of box
culverts. Natural bottom culverts have non-structural bottoms that allow for the restoration of a
natural streambed. The natural bottom culverts will improve conditions of the streams by
' providing enhanced aquatic habitat, in comparison to conventional box culverts. The remaining
culvert/pipe system replacements will largely involve direct in-kind replacement. A number of
these culverts include bends, sanitary sewer crossings, and drainage structures. In certain
' instances the culvert inlet and outlet elevations match the proposed stream elevations and cannot
be buried due to the presence of sewer lines that cross beneath the pipe system.
' Gabions proposed for this project are rock-filled baskets or cages, and are used to build support or
an abutment where erosion poses a threat, such as loss of property. This technique offers sturdy
support and enforcement and is feasible in that it meets the mechanical needs of the channel.
Gabions can be utilized in areas where space is limited, such as in urban neighborhoods where
' dwellings are located close to the stream channel, and have been targeted to replace failing
retaining walls. Gabions are necessary on a short, 40 bf/lf segment of perennial stream, since re-
sloping of the bank is not possible due to the close proximity of single-family dwellings. The
' property is near the top of bank and there is not enough room for a 2:1 slope. The use of gabions
on this vertical bank will provide protection for the streambank and the adjacent structure. While
the use of gabions provides a solution to the eroding streambank problem, installation may result
' in short-term impacts to stream habitat, including the suppression of existing vegetation in the
streambank.
' Culvert maintenance construction activities will generally begin at the downstream project limit
and will proceed to the upstream project limit, so that increased stream flow volume resulting
from pipe upsizing is accommodated. However, minor variations may occur to accommodate
construction schedules, easement acquisitions, and property owner requests. Streambank
' stabilization measures will typically progress from upstream to downstream. Construction access
and activities will take place from the top of the bank, and construction vehicles will not be
driven into the stream. There should be no adverse impacts to the stream's hydrologic or
' hydraulic performance as a result of the proposed storm drainage improvements.

Summary
February 5, 2003
A combination of storm water management measures was determined to be the preferred alternative for
the proposed CIP. These storm drainage improvement measures include:
1) Approximately 1,469 If (2,653 bf) of soil bioengineering streambank stabilization (1,225 if [2,181 bf]
along perennial channel and 2441f [472 bf] along intermittent, aquatically unimportant channel),
2) Approximately 1,663 If of storm pipe replacement (1,5021f along perennial channel and 161 if along
intermittent, aquatically unimportant channel),
3) Approximately 40 bf/lf of gabion installation (along perennial channel),
4) Approximately 351 If of riprap placement (291 If along perennial stream channel and 60 if along
intermittent, aquatically unimportant stream channel), at four inlets and seven outlets, with aprons
ranging in length from 20 feet to 55 feet.
5) Approximately 601 if of new storm pipe installation.
Soil bioengineering streambank stabilization was selected on the basis of its low environmental impact
and habitat benefits. Gabion utilization has been limited to a single location, where this approach should
produce few impacts and will increase streambank stability. New storm pipe extent has been minimized
to the maximum extent practicable, and will include replacement of two conventional culverts with
natural bottom arched culverts. Following project completion, CSWS will monitor stability and success
of the proposed measures.
Block 19. Proposed Project Purpose
The Enfield Road/Windsor Park CIP is one of the CSWS Capital Improvements Projects planned for
implementation throughout the city. The City of Charlotte CIP program was established to address large,
complex, costly, and interconnected drainage problems. When multiple storm water drainage problems
are present in a single geographic area, these individual problems are grouped together so that the CSWS
can address the issues as efficiently and as cost-effectively as possible. CIF's require extensive planning,
detailed design, easement acquisition, and construction, and may take approximately two to five years to
complete, from the planning stage through construction.
The Charlotte Storm Water Program, the first of its kind in North Carolina, was implemented in January
1993. Since the program's inception, CSWS has been committed to providing Charlotte communities
with a quality storm drainage and conveyance system by monitoring and managing functional storm water
systems that provide for public safety. Operation of this CSWS program has revealed the magnitude of
drainage system needs in Charlotte. In November 1995, CSWS, along with City staff and the Charlotte
City Council, developed a comprehensive strategy for the storm water program. Within this strategy was
a goal to reduce streambank erosion and downstream sedimentation. CSWS has now initiated a 15-year
program to restore degraded channels by re-establishing vegetation on stream banks and by
restoring/maintaining the physical stability of these streambanks.
CSWS has an obligation to the neighborhoods of Charlotte to maintain and improve area storm water
drainage and conveyance systems, in order to protect public safety, to minimize property impacts, and to
enhance the natural and beneficial functions of waterways and their associated riparian corridors. In
keeping with this commitment, CSWS has proposed improvements to the storm drainage and conveyance
system within a portion of the Briar Creek watershed that encompasses the Enfield Road/Windsor Park
neighborhood. CSWS has proposed storm water improvements at various locations within the
approximate 378-acre watershed. The need for these improvements is based on the severity of flooding
8

Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application February 5, 2003
' LAW Project 30100-0-0369, Phase 04
and streambank erosion along the stream channels within these neighborhoods. The localized flooding
' and eroding streambanks currently threaten adjacent properties, jeopardize public safety, and impair water
quality in the project area channels.
' To minimize property flooding and enhance the natural benefits of the waterway, CSWS is proposing
streambank stabilization at various locations along approximately 1,469 If (2,653 bf) of the approximately
3,350 If of jurisdictional stream channels within the study area, and new pipe placement within 601 if of
jurisdictional stream channel (Attachment B). In addition, CSWS plans to conduct minor maintenance
' activities, such as culvert replacements, along approximately 2,054 if of channel within the study area
(Attachment B, Figure 2c). See Block 18 response, above, for detailed discussion. Additionally,
aesthetically unpleasing debris, such as clothing, trash, and bicycles, will be removed from stream
' channels within the project area. Without the proposed improvements, erosion and pollution will
continue to be a problem. Left in their current state, eroding streambanks and flooding conditions will: a)
jeopardize public safety by impacting property, structures, and roadways, and will b) perpetuate the
' continued degradation of the stream environment and associated riparian habitat. The proposed project
will help to satisfy CSWS's goal of maintaining and improving area storm water drainage systems in the
interest of local communities, wildlife, and natural resources. Completion of this project will result in
' positive, long-term benefits to: storm water drainage, streambanks, stream channels, adjacent properties,
and habitat resources (both aquatic and terrestrial). Short-term adverse impacts during construction
should be offset by long-term benefits to the watershed.
Block 20. Reason(s) For Discharge
' I. Streambank Stabilization
Due primarily to urban constraints, Rosgen Priority IV restoration (utilizing soil bioengineering with rock
' toe protection, gabions, and riprap) was concluded to be the recommended alternative for the proposed
channel stabilization efforts. These constraints include the presence of residential structures within 75
feet of the top of the channel bank.
' A. Soil Bioengineering
' Restoring and improving the streambank corridor with vegetation will enhance terrestrial wildlife
habitat, will shade the stream channel (thereby reducing water temperature), will contribute
coarse particulate organic matter (CPOM), will reduce streambank erosion and downstream
' sedimentation, and will provide aesthetic benefits. The soil bioengineering techniques that will
be used for this project will consist primarily of live staking, fascine installation, and toe
protection. Plant materials to be used will likely include silky willow (Salix sericea), silky
dogwood (Corpus amomum), elderberry (Sambucus canadensis), Virginia willow (Itea virginica),
' and coralberry (Symphoricarpos orbiculatus). Additionally, coir fiber rolls/logs, natural fiber turf
reinforcement matting, and a native riparian seed mix will be used along some stream reaches.
To protect against erosive scour, riprap will be used to armor approximately the bottom 2 feet of
' the channel bank along some stream reaches. This rock toe protection will vary based upon
calculated levels of shear stress. This riprap should provide protection against shear stresses
exceeding the capabilities of soil bioengineering techniques.

Section 404 Individual Permit Application
LAW Project 30100-0-0369, Phase 04
B. Gabion Installation
February 5, 2003
Approximately 40 bf/lf of gabions will be necessary along a perennial stream near the intersection
of Birchcrest Drive and Woodleaf Road, since 2:1 re-grading of the streambanks is not possible
(due to the close proximity of single-family dwellings. The use of gabions should provide
sufficient stability for the protection of the streambank and adjacent homes. See Block 18
response, above, for greater discussion of gabions.
R. New Pipe Placement
New pipe placement is proposed at six specific locations within the project area, for a total of 491
If in perennial stream channels and 1101f in intermittent, aquatically unimportant channels. The
placement of new pipe was deemed necessary in order to create a hydraulically efficient system
upstream of Tamerlane Drive as well as between Birchcrest and Gladstone Drive. The short
stream segment upstream of Tamerlane Drive falls between a downstream pipe system
(approximately 570 feet long) and an upstream pipe system (completely enclosed). The existing
channel is shallow, and due to the pipe systems located on either side, engineering studies have
concluded that this channel segment is contributing to the hydraulically inefficient system,
resulting in yard and crawlspace flooding. As previously stated, significant widening and
deepening of this channel would necessitate encroachment on private property, including impacts
to structures located adjacent to the channel. An efficient system can be created with the
placement of 36-inch RCP at this channel location, requiring limited alteration of the surrounding
topography. Placement of new pipe upstream of Tamerlane Drive will result in impacts to two
segments of perennial stream channel, totaling 3061f.
The placement of new pipe on a stream segment located between Birchcrest and Gladstone Drive
is needed for essentially the same reasons as stated above for the Tamerlane Drive stream
segment. The existing channel and floodplain have been severely encroached upon by residential
development, with structures approximately 40 years old. This stream channel also falls between
two pipe systems and is contributing to the inefficient overall system. The placement of a new
36-inch RCP in the existing channel will result in impacts to approximately 164 if of perennial
stream channel, but should alleviate yard and crawlspace flooding in the project area.
A minor pipe extension between Enfield Road and the main channel is needed to save a private
shed located adjacent to the channel. Without this pipe extension, the homeowner's shed would
be impacted by other channel improvements upstream. Placement of this new 36-inch RCP will
result in impacts to approximately 31 If of intermittent, aquatically unimportant stream channel.
Placement of new pipe upstream of Darbrook Drive is necessary in order to create a hydraulically
efficient system. The existing channel is comprised of grouted riprap lining and the channel and
floodplain have been severely encroached upon by historic residential development.
Additionally, the channel is located between the Darbrook Drive culvert and a completely
enclosed upstream pipe system. The placement of new 42-inch RCP in the existing channel will
result in impacts to approximately 791f of intermittent, aquatically unimportant stream channel.

III. Avoidance/Minimization
February 5, 2003
Various steps were taken to avoid and minimize impacts to waters of the U.S., including the following:
A) Approximately 3,350 if of jurisdictional stream channels exist in the project area. In order to
minimize overall project impacts, only stream reaches experiencing significant bank erosion have
been selected for stabilization. The proposed stabilization efforts will be implemented along
approximately 1,469 If/2,653 bf of channel. The remaining channel should not be directly
affected by project-related activities. It is additionally anticipated that stabilization of eroded
channel now will help reduce potential erosion of other channel reaches in the future, by reducing
peak discharge velocities and downstream sedimentation.
B) The proposed combination of extensive "soft" stabilization measures (soil bioengineering) and
limited "hard" stabilization techniques should minimize overall project impacts. Since
streambank stabilization through soil bioengineering produces few impacts and significant habitat
value, this approach is proposed for the majority of stream corridors throughout the project area.
C) In order to minimize potential impacts associated with culvert maintenance and replacement
activities, two replacement culverts on perennial streams will utilize natural bottom (three-sided)
designs, rather than implementing direct in-kind replacement (at Sudbury Road and Dunaire
Drive). These natural bottom culverts, consisting of aluminum arch culverts on concrete strip
footings, will provide greater environmental benefits than direct in-kind replacement of box
culverts. Natural bottom culverts have non-structural bottoms that allow for the restoration of a
natural streambed. The natural bottom culverts will improve conditions of the streams by
providing enhanced aquatic habitat, in comparison to conventional box culverts.
D) The use of riprap for channel stabilization has been minimized to the maximum extent
practicable.
E) The proposed project has been planned to minimize project impacts and effectively address
hazards associated with flooding and streambank erosion.
F) The proposed activities in waters of the U.S. represent the least environmentally damaging
alternative and are concluded to be in compliance with the U.S. Environmental Protection
Agency's 404(b)(1) guidelines.
IV. Conceptual Mitigation Approach
Minor excavation to facilitate construction will take place during installation of culverts, pipe systems,
riprap, gabions, and grade control structures. However, existing channel cross-sectional dimensions will
be generally maintained during streambank stabilization efforts, riprap placement, and culvert/pipe
' maintenance and replacement activities. Natural contours of temporarily disturbed areas will be re-
established following completion of implementation efforts.
It is not anticipated that compensatory mitigation will be required for the soil bioengineered streambank
' stabilization along perennial channels (1,225 If/2,181 bf) since completion of these activities is expected
to result in substantial improvements to the aquatic and riparian ecosystem. However, it is anticipated that
compensatory mitigation would be required to offset permanent losses of perennial stream channel for the
' use of gabions (40 bf/lf), and the placement of new pipe (491 If), totaling 531 If. As compensatory
mitigation for these impacts, CSWS proposes to utilize 531 if of mitigation credits from the Hope Park
Branch Stream Restoration project (USACE Action ID No. 200130492). The Hope Park Branch project
' involved approximately 3,661 if of restored channel on Hope Park Branch (Attachment B). Prior to
restoration, this channel was an important, perennial stream with low sinuosity, moderate incision, poor
in-stream habitat structure, and erosion to bedrock (in some locations). The restored channel was
' designed to be consistent with DWQ's definition of stream restoration, as established in the May 10, 2000
1 11
Enfield Road/Windsor Park Capital Improvements Project
Section 404 Individual Permit Application February 5, 2003
LAW Project 30100-0-0369, Phase 04
"Interim, Internal DWQ Policies on Stream Mitigation Options and Associated Macrobenthos
Monitoring." The restoration involved: 1) formation of a stable channel with appropriate dimension,
pattern and profile; 2) reconnection of the channel to the floodplain by bed elevation adjustment; 3)
placement of natural material, such as root wads and rock vanes in the stream to improve stability and
enhance aquatic habitat; and 4) stabilization of stream banks with herbaceous and woody vegetation to
improve aquatic habitat. The restoration plan was approved by the USACE on March 13, 2001 and was
implemented in the summer of 2002. CSWS has previously utilized 1,760 if of Hope Park's available
3,661 if of credit on separate CSWS projects (Kendall and Lynmont projects). CSWS will meet the
compensatory mitigation requirements of the USACE and DWQ as a condition of the requisite Section
404 permit and Section 401 certification for this project.
Measures will be employed to limit sediment from moving downstream. Potential impacts to
jurisdictional waters of the U.S., associated with sedimentation and erosion will be minimized through the
implementation and maintenance of a State-approved erosion and sedimentation control plan. The goal of
this plan will be to minimize erosion and retain sediment, to the maximum extent practicable within the
construction area. Measures will include limiting construction to dry weather periods, exposing no more
soil along the stream bank than can be temporarily stabilized within "one-days-work" (i.e., approximately
100 If), and, if possible based on channel width, temporarily diverting stream flow away from the bank
undergoing repair.
Block 21. Type(s) of Material Being Discharged and the Amount of Each Type in Cubic Yards
Gabions proposed for this project are rock-filled baskets or cages, and are used to build stabilize
streambanks when erosion poses an immediate threat to adjacent properties and/or structures. Riprap will
be used along approximately 977 (1,869 bf) of perennial stream, to armor approximately the bottom two
feet of some stabilized streambank areas (approximately 140 cubic yards of riprap). Coir fiber rolls/logs
will be used along 2481f (312 bf) of perennial stream, for toe protection in locations where sheer stress is
acceptably low. The placement of 491 if of reinforced concrete pipe (RCP) will be conducted at four
locations in perennial stream channels, and clean fill material will be placed over the pipe.
Approximately 244 If (472 bf) of riprap will used as toe protection along intermittent, aquatically
unimportant stream channels (approximately 35 cubic yards of riprap). In conjunction with maintenance
activities, riprap in existing aprons will be replaced with new material.
Block 22. Surface Area (in Acres) of Wetlands or other Waters Filled
The majority of streambank stabilization efforts will be implemented using soil bioengineering techniques
and will occur along 1,225 If (2,181 bf) of perennial stream channel and 244 If (472 bf) of intermittent,
aquatically unimportant stream channel (total impacts to approximately 1,469 If (2,653 bf) of stream
channel). Toe protection measures associated with these bioengineering stabilization techniques may
impact approximately 0.05 acre of streambed (approximately 2,340 square feet). Gabion installation
along 40 bf/lf of streambank may result in impacts of less than 0.01 acre (200 square feet). New pipe
placement is proposed at six specific locations within the project area, for a total of 491 If in perennial
channels and 110 if in intermittent, aquatically unimportant channels, resulting in impacts to
approximately 0.06 acre (2,400 square feet). The proposed project may impact a total of approximately
0.12 acre of jurisdictional waters of the U.S.

Enfield Road/Windsor Park Project
Storm Drainage Improvements
Charlotte, North Carolina
LAW Project No. 30100-0-0369, Phase 04
Dear Mr. Cantrell:
FIL E
The City of Charlotte Storm Water Services (CSWS) has retained Law Engineering and Environmental
Services, Inc. (LAW) to provide environmental services for the above-identified storm drainage
improvement project. In order that LAW may fully evaluate and consider any potential effects of the
project, we are hereby requesting that you respond in writing concerning any beneficial or adverse
' impacts relative to the interests of your agency. The project vicinity and location are presented on the
attached Figure 1.
As indicated on Figure 1, the proposed project area is located north of Central Avenue between Brier
Creek and Sharon Amity Lane. The limits of the project extend from approximately 500 feet north of
Central Avenue north to Sudbury Road and northwest to Eastway Drive. Waters of the U.S. located
within the proposed project area include an unnamed tributary to Brier Creek. The project area is
primarily comprised of residential development, and proposed project activities include storm drainage
improvements. As such, project activities associated with these improvements may involve culvert
placement and replacement, streambank stabilization and/or restoration of the unnamed tributary to Brier
Creek and associated channels. It is anticipated that proposed channel improvements will largely occur
within the bed and bank of the existing channels. An estimated 6300 linear feet of stream channel may be
impacted by the project. The USGS Topographic Map that covers the project area is Charlotte East,

Dear Ms. Pownall:
The Natural Heritage Program database bas a record for Carolina thistle (Curium
carolinianum) on the grounds of the Methodist Home, just to the north of your site.
This plant bas no federal status, but is a state candidate. No other rare species. natural
connunities. or significant area are recorded within two miles of the site. A number
of other rare plants are known from eastern Mecklenburg County, including the
federally listed Scbweinitz's sunflower (Helianthals schweininif). which oocura in
habitat similar to that of Carolina thistle.
Sincemly.

Re: Proposed Enfield Road/Windsor Park Stone Drainage Improvements, Charlotte,
' Mecklenburg County, 01-E-4300-0563 and ER 01-7719
Dear Mr. Iagnocco:
' Thank you for your letter of September 28, 2000, concerning the above project. The northern
section (Phase 1) of the subject project was received previously from the Clearinghouse as an
' Environmental Assessment in May 2000. This appears to be a southern extension to that same
project (Phase 4). The EA correctly stated on page 12 that no archaeological sites are recorded
in the proposed project area. No archaeological survey was recommended at that time.
' There are no known archaeological sites within the proposed project area. Based on our present
knowledge of the area, it is unlikely that any archaeological resources, which may be eligible for
' inclusion in the National Register of Historic Places, will be affected by the project construction.
We recommend that no archaeological investigation be conducted in connection with project.
The above comments are made pursuant to Section 106 of the National Historic Preservation Act
' and the Advisory Council on Historic Preservation's Regulations for Compliance with Section
106 codified at 36 CFR Part 800..
' Thank you for your cooperation and consideration. If you have questions concerning the above
comment, contact Renee Gledhill-Earley, Environmental Review Coordinator, at 919/7334763.
' Sincerely,

Gabion stream stabilization will impact 40 bf of stream. There will be 601 if of piping impacts. As a
condition of the 401 Water Quality Certification for this project, it is anticipated that compensatory
mitigation will be required to offset permanent losses of perennial stream channel for impacts associated
with the placement of pipe (491 If) and gabions (40 bf). The applicants propose to use mitigation credits
from the Hope Park Branch Stream Restoration Project.
Potential impacts to streams will be minimized through implementation and maintenance of a State-
approved erosion and sedimentation control plan and adherence to conditions of the 401 Water Quality
Certification. Any buffer areas disturbed as a result of the proposed project will be stabilized and
reseeded with emphasis on reforesting stream banks. Long-term water quality is expected to improve
through a reduction in streambank erosion and sedimentation.
Land use changes are not anticipated to result from the project. The project area is a fully developed,
urban neighborhood. Changes to drainage patterns are not anticipated and no wetlands have been
identified within the proposed project limits.
Many of the proposed stabilization reaches are currently protected from development by Mecklenburg
County's Surface Water and Management riparian buffer ordinance. Naturally vegetated buffers, ranging
in width from 35 feet to 100 feet depending on the size of the drainage basin, are protected. These buffers
will help protect the proposed stream stabilization project and stream channels from stormwater impacts.
' The Division of Water Quality has concluded that the proposed project will not result in significant
impacts to the environment. This decision is based upon information provided in the EA and review by
governmental agencies. This EA and Finding of No Significant Impact (FONSI) are prerequisites for the
issuance of a 401 Water Quality Certification by the Division of Water Quality. An environmental
' impact statement will not be prepared for this project. This FONSI completes the environmental review
record, which is available for inspection at the State Clearinghouse.
