Charlotte Storm Water Services (CSWS) is submitting this letter in response to your
request for additional information on the proposed Columbus Circle/Ashley Park-
Westerly Hills Storm Water Capital Improvement Project (Columbus Circle)(DWQ #04-
0940). As discussed last week, some of the impacts were overlooked and have been
inadvertently understated in the Pre-construction Notification (PCN) for this project,
dated June 4, 2004. The following is a list of impacts that were overlooked or
misrepresented in the PCN:
o Sheet 33-47 linear feet of channel lost to realignment of culvert at Denver Avenue.
There was a typographical error on the plans for this culvert replacement.
o Sheet 38-19 linear foot pipe extension with a 10 foot rip rap apron. This pipe
extension was not included in the original 70% design submittal, and it was missed
during the 95% design review.
These additional impacts increase the total loss of open channel due to culvert and pipe
replacements to approximately 85 linear feet. CSWS is submitting this letter to amend
and update the impact totals in the PCN for Columbus Circle. If you have any additional
questions, please don't hesitate to contact me at [phone] or

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 figures (Attachment B),
and an accompanying request for jurisdictional determination (Attachment C). This PCN is being
' submitted for Nationwide Permit (NWP) No. 3, NWP No. 13, and NWP 27 for the above-referenced
Capital Improvement Project (CIP). CSWS has retained MACTEC Engineering and Consulting, Inc.
(MACTEC) to provide permitting services for this project. This submittal is the product of a
cooperative effort between CSWS, MACTEC, and Armstrong Glen, P.C. (AG). AG is providing
' design/engineering services to CSWS for this project.
CSWS requests that the USACE and the DWQ consider the following document as the PCN for
project coverage through NWP No. 3, NWP No. 13, and NWP No. 27 for the Columbus Circle
Capital Improvement Project. CSWS requests that the USACE and the DWQ also consider the
following document as the PCN for project coverage through NWP No. 3 for the Ashley
Park/Westerly Hills Capital Improvement Project. The Columbus Circle CIP study area is located
within the overall Ashley Park/Westerly Hills CIP study area. In order to simplify review of these
projects, both CIP's have been combined in this single PCN document.
Project Overview
' CSWS, in conjunction with MACTEC, is submitting this PCN for authorization under NWP No. 3
- Maintenance (Water Quality Certification [WQC] 3376), NWP No. 13 - Bank Stabilization
(WQC 3399), and NWP No. 27 - Stream and Wetland Restoration Activities (WQC 3399). The
' proposed CIP's: 1) will result in over 500 if of streambank stabilization activities, 2) may require
minor changes in riprap extent (at culvert replacement locations), and 3) may involve the
installation of current deflectors and modifications of the streambed/streambanks (to create stream
meanders). As a result, this PCN is being provided in accordance with Nationwide Permit
' "notification" requirements for NWP No. 3, NWP No. 13, and NWP No. 27.

Columbus Circle/Ashley Park/Westerly Hills Capital Improvements Projects June 4, 2004
Section 4041401 Pre-Construction Notification
AMCTEC Project 6229030639, Phase 29
CSWS is proposing storm drainage and conveyance improvements in the Columbus Circle, Ashley
Park and Westerly Hills neighborhoods, along several unnamed tributaries to Taggart Creek and
Stewart Creek. The proposed project area is generally bordered by Freedom Drive to the northeast,
Wilkinson Boulevard to the south, and Interstate 1-85 to the northwest, in Charlotte, North Carolina
(Attachment B, Figure 1). 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 Denver Avenue, south of
Freedom Drive, and north of Wilkinson Boulevard.
To minimize property flooding and enhance the natural benefits of local waterways, CSWS is
proposing approximately 169 linear feet (if) of 'hard' streambank stabilization, approximately 900 If
of 'soft' streambank stabilization, various culvert/riprap apron replacements (approximately 19 If of
culvert extension impact), and approximately 1,625 If of stream enhancement (Attachments A and B).
Without the proposed improvements, streambank erosion and localized flooding will continue to be a
problem in the affected study area neighborhoods. 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. Repair
and/or augmentation of riprap aprons will also be necessary to meet city standards. Proposed 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 l 0-year storm event. Riprap aprons at pipe
outfalls have been designed to be the minimum size required for energy dissipation. During project
implementation, 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
periodic flooding will jeopardize public safety by impacting property, structures, and roadways, and
will perpetuate the continued degradation of the aquatic 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. Photo-documentation is included in Attachment B (Figure 2) and Attachment D.
An 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 practicable, `soft' soil bioengineering streambank
stabilization or stream enhancement approaches have been proposed (including streambank
grading, rock cross vanes, coir fiber matting, and native riparian seeding).
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, culvert
maintenance/replacement efforts, and stream enhancement activities are proposed under USACE
Nationwide Permits No. 13, 3, and 27, respectively. Activities affecting jurisdictional waters of
the U.S. will not begin prior to receipt of the requisite Section 404 permit and corresponding
Section 401 WQC.

' Jurisdictional Waters of the U.S.
Approximately 16,100 If of jurisdictional waters of the U.S. are located within the anticipated
' study area. Project activities will primarily be conducted within the bed and bank of these stream
channels. Possible wetland areas have been evaluated using the Routine On-Site Determination
' method as described in the 1987 "Corps of Engineers Wetlands Delineation Manual"
(Environmental Laboratory, 1987). Field reconnaissance conducted by Carolina Wetland Services
(CWS) on November 7, 12, and 26 of 2001 revealed the presence of two potential wetland areas
' (Attachment B, Figure 2).
The primary perennial streams located in the study area include an unnamed tributary to Taggart
Creek and an unnamed tributary to Stewart Creek. The unnamed tributary to Taggart Creek
' generally flows southwest through the project area until converging with Taggart Creek. The
unnamed tributary to Stewart Creek generally flows east through the northeastern corner of the
study area. Vegetation associated with study area stream channels varies from maintained lawns
' to forested riparian corridors.
CWS completed a series of stream assessments on the subject channels utilizing the USACE
' Intermittent Channel Evaluation Form and the DWQ Stream Classification Form on November 7,
12, and 27 of 2001 (Attachment Q. Figure 2 in Attachment B (Approximate Waters of the U.S.
Boundary Map) identifies the stream segments assessed by CWS and the findings of those
' assessments.
Impacts to Waters of the U.S.
' Completion of the proposed CIP's will result in unavoidable impacts to jurisdictional stream
channels (Table 1). These impacts will include approximately 900 If of `soft' soil bioengineering
streambank stabilization (along approximately 405 If of perennial channel and approximately 495
' If of intermittent channel), approximately 169 if of `hard' streambank stabilization along perennial
channel (riprap toe protection), and various culvert/riprap apron replacements (including
' approximately 19 If of culvert extension impact to perennial stream). Approximately 1,625 if of
stream enhancement is also proposed along perennial stream. A detailed description of project
impacts is included in the PCN Joint Form (Attachment A). Construction plan excerpts are
included in Attachment E.

Engineering Analysis and Design Summary (Armstrong Glen)
The purpose of the Columbus Circle CIP is to address storm drainage issues identified from citizen
requests. Citizen requests include street flooding, first floor flooding, crawl space flooding, and
stream bank erosion. The initial phase of the project included a planning study to evaluate the
existing conditions of the storm drainage conveyance systems throughout the project area and
make recommendations to bring undersized drainage features up to current City of Charlotte
design standards. Recommendations include upsizing roadway culverts and pipe systems,
providing additional catch basins and inlets to collect surface drainage, and to provide measures
for eroding stream banks.
The majority of the primary conveyance systems are comprised of closed pipe systems. The
remainder are comprised of short open channel reaches and pipe outfall ditches. Closed pipe
systems were analyzed and designed using HYDRAFLOW storm sewer modeling software.
Additional models used for this project included FLOWMASTER (for short stream reaches) and
HEC-RAS (for the Bristol Drive study). Peak discharges were calculated using the Rational
Method. The HEC-RAS study for the Bristol Drive channel included an assessment of existing
water surface elevations, along with an evaluation of potential cross-sectional changes that would
help lower future water surface elevations. The HEC-RAS analysis showed significant road
flooding for the 25-year storm event along Bristol Drive. Additionally, the Wilson Avenue culvert
overtops for the 2-year storm event. HEC-RAS calculations are included in Attachment F.
The Bristol Drive area, in addition to severe flooding, contains a well entrenched, severely eroding
stream that requires significant stabilization measures to ensure the protection of the adjacent road
(Bristol Drive) from ever becoming undermined. The proposed channel stabilization
improvements consist mainly of the placement of rock cross-veins to promote in channel stability
by forming large, appropriately spaced pools to dissipate energy and provide habitat for aquatic
organisms and fish. Bankfull benches are not utilized in this stabilization design because of the

' constraints placed on the width of the stream by the adjacent road surface and terrace. In order to
determine a representative channel design to convey more frequent storms, several publications by
Rosgen (1994, 1996, and 1997) were consulted. Additionally, Doll et al. (2002) was used to
' determine the appropriate channel dimensions for use on this project.
It should be noted that a full Rosgen analysis was not completed for this project. Values used for
' the design of the Bristol Drive stream stabilization were generated from previously collected
reference data from various locations and the relationships utilized generally follow Rosgen (1994,
1996, and 1997). Vane design followed Rosgen (2001). Proposed improvements to the Bristol
' Drive channel include grading banks to 1.5:1 side slopes, replacing culvert at Station 1+50 (Sheet
35) with a pedestrian bridge, re-routing channel from Station 14+50 to Station 16+20, and
replacing the Wilson Avenue culvert (part of the Ashley Park Neighborhood Improvement
Project). These improvements greatly reduced the water surface elevation along the channel.
The improvements to the perennial channel along Bristol Drive resulted in a dramatic reduction in
' water surface elevation for all storm events. The improvements will eliminate road flooding for all
storm events. The water surface elevation remains in the bank for the 100-year storm [in] most
places. The proposed Wilson Avenue culvert will offer 100-year flood protection from
' overtopping.
The outfall of Line `A' includes approximately 45 linear feet of perennial channel (Stream J) re-
shaping, brush removal, and debris removal (Sheet 4). Approximately 50 linear feet of rip rap
apron and channel protection will be constructed downstream of the 6' x 5' concrete box culvert
(Structure Al, Plan Sheet 4) to stabilize the outlet and to replace the existing riprap channel lining.
Approximately 373 linear feet of (intermittent unimportant) channel (Stream I) will be re-shaped
between Structure F2 (Sheet 16) and Structure F3 (Sheet 17). The existing channel is clogged with
garbage, appliances, furniture, brush, etc. and suffers from erosion because of the blockages.
Recommendations include debris removal and re-grading of the channel profile and channel banks.
The channel will be protected with permanent erosion control matting and vegetation.
' Line `Q' (Sheet 21), Line `R' (Sheet 22), Line `S' (Sheet 23), and Line `W' (Sheet 25) are wet
weather outfalls draining small street systems. These channels are not jurisdictional. Line `Q'
proposed re-shaping 20 linear feet of outfall ditch and construction of 10 linear feet of Class I rip
' rap apron. All outfall channels will be protected with permanent erosion control matting. Line `R'
proposes construction of 10 linear feet of Class I rip rap apron. Line `W' proposes re-shaping 115
linear feet of channel and construction of 10 linear feet of Class I rip rap apron.

Line `CE' (Sheet 29) is a wet weather outfall that drains street systems. Line `CE' proposes re-
shaping of 225 linear feet of existing non-jurisdictional channel and construction of Class I rip rap
apron.
Line `PA' is an existing closed pipe system that is being upsized (Sheet 30). Line `PA' proposes
re-shaping 50 linear feet of existing outfall channel (intermittent, unimportant) and construction of
48 linear feet of Class I rip rap apron.
Rip rap aprons are also proposed for construction at five outfalls to non jurisdictional channels.
These outfalls are located south of Sonora Lane (Sheet 28), northeast of Davis Avenue (Sheet 24),
north of Crispin Avenue (Sheet R40), north of Highland Street (Sheet R7), and northeast of
Garibaldi Avenue (Sheet R313).
The existing culvert beneath Denver Avenue and Alleghany Street will be replaced with dual 8' x
8' RCBC. The culvert inverts will be set one foot below the natural channel bottom. The 78 linear
foot channel downstream of Headwall DAI (Sheet 33) will be graded to accommodate the new
box culverts. A portion of the existing perennial channel will be backfilled once the old culverts
are replaced. Approximately 136 linear feet of stream channel will be re-shaped (Sheets 33 and
34) between DA2 and DA3 to create a smooth channel bend. The stream channel will be
stabilized with toe rip rap protection along the outside bend of the stream and all newly exposed
stream banks will be stabilized with permanent erosion control matting. Approximate 45 linear
feet of stream channel will be re-shaped (Sheet 34) upstream of Headwall DA6 in order to tie-in
the new wing walls to the existing stream channel.
Regulatory Implications
As part of its Surface Water Improvement and Management (SWIM) Program, the Mecklenburg
County Land Use and Environmental Services Agency (LUESA) has established riparian buffer
protection areas along streams throughout Mecklenburg County (including Taggart Creek and
Stewart Creek and their tributaries). SWIM buffer widths of 35 feet and 50 feet have been
established for portions of the unnamed tributary to Taggart Creek in the study area (Attachment
B, Figure 4). SWIM buffer widths of 35 feet have been established for portions of the unnamed
tributary to Stewart Creek in the study area (Attachment B, Figure 4). Following project
implementation, disturbed areas will be stabilized, to comply with SWIM buffer regulations.
CSWS will replace buffers where practicable. 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, 2003). 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 exaltatutn), smooth coneflower (Echinacea laevigata),
Schweinitz's sunflower (Helianthus schweinitzii), and Michaux's sumac (Rhus miehauxii). These
' species are not anticipated to occur in the study area, due to existing land uses and the extent of
previous disturbance and development associated within the project area.
MACTEC submitted a letter to the United States Fish and Wildlife Service (USFWS) dated
December 2, 2003 requesting comments regarding beneficial or adverse affects of the proposed
storm water improvement project, relative to the interests of the agency (Attachment G). As of the
' date of this PCN, no response from the USFWS has been received.
MACTEC also contacted the NCNHP on December 2, 2003 and requested comments regarding
beneficial or adverse affects of the proposed storm water improvement project, relative to the
' interests of the agency. Subsequent correspondence (dated December 23, 2003) stated that the
NCNHP has no record of rare species, significant natural communities, or priority natural areas at the
site nor within a mile of the project area (Attachment H).
Cultural Resources
MACTEC submitted a letter to the North Carolina Department of Cultural Resources (NCDCR) on
December 2, 2003, requesting comments regarding beneficial or adverse affects of the proposed
storm water improvement project, relative to the interests of the agency. Subsequent
' correspondence (dated December 8, 2003) stated that the NCDNR is aware of no historic resources
which would be affected by the project (Attachment I).
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 (including
"culverting, relocation, channelization or streambank stabilization including gabions, rip rap, and
similar hard structures") require SEPA review. Since the proposed CIP activities discussed in this
NWP application will disturb less than 500 If of perennial stream channel with hard structure,
these activities do not exceed the SEPA review threshold and therefore do not require the
' preparation of an environmental assessment (EA) and corresponding SEPA review.

t 10. Describe the purpose of the proposed work: To minimize property flooding and enhance
the natural benefits of local waterways CSWS is proposing approximately 169 linear feet (If) of
' 'hard' streambank stabilization approximately 900 If of 'soft' streambank stabilization, various
culvert/riprap apron replacements (approximately 19 If of culvert extension impact), and
approximately 1,626 If of stream enhancement. Without the proposed improvements,
streambank erosion and localized flooding will continue to be a problem in the affected study
' area neighborhoods 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. Repair and/or
' augmentation of riprap aprons will also be necessary to meet city standards. Proposed
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 During proiect implementation 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 periodic flooding will jeopardize
public safety by impacting property, structures, and roadways, and will perpetuate the
continued degradation of the aquatic environment and associated riparian habitat. The
' proposed proiect 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 proiect 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 loner-term
benefits to the watershed.
' 11. List the type of equipment to be used to construct the project: Track hoes, back hoes,
bulldozers dumptrucks, and hand tools
' 12. Describe the land use in the vicinity of this project: Primarily single-family residential (80%),
commercial (15%) and institutional (5%). The majority of commercial and institutional land
use occurs along major roadways within the noted study areas.
' 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.

Impact Justification -(Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site :on6traints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
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 Columbus Circle & Ashley Park/Westerly Hills Capital Improvement Projects. To
determine appropriate methods for addressing storm drainage inadequacies (resulting in
streambank erosion and flooding), the project area and existing storm drainage system were
evaluated by CSWS, in cooperation with Armstrong Glen, P.C. (AG) and MACTEC.
A 'no action' alternative was also considered for the proposed culvert replacement activities.
However, this alternative would allow continued flooding and degradation of the existing culverts.
This alternative would not offer public safety benefits, and would not satisfy CSWS
responsibilities to the affected communities in the study area.
Streambank stabilization alternatives included 'no action,' `hard' stabilization, soil bioengineering,
aabion installation, stream enhancement, and stream restoration.
The proiect area poses a number of challenges, including existing riparian habitat, steep vertical
streambanks, buried utility lines, and residences/structures in close proximity to stream channels.
Considering these constraints and the necessity of the proposed improvements, some impacts to
unnamed tributaries of Taggart Creek and Stewart Creek in the project area will be unavoidable.
A. No-Action Alternative
A no-action alternative was initially considered for the study area. As discussed earlier, if
improvements are not made within the project area drainage system, continued floodinq of
neighborhood streets, crawlspaces, basements, and yards will likely occur. Additionally, existing
channel erosion will continue and will exacerbate sedimentation and clopping of stream culverts.
Ultimately, this alternative could result in the threat of structural damage, along with public
health/safety concerns regarding continued flooding of low elevation areas. After evaluating the
condition of decaying roadways, culverts, and eroding streambanks, the no-action alternative was
Page 8 of 16
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
have allowed 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.
' B. Culvert Replacement - Partial Repair
' The partial repair alternative, involving replacement of undersized culverts and pipe systems, was
determined to provide greater conveyance capacity beneath roadway crossings (and developed
areas). Analyses indicated that this alternative could provide a means of reducing localized
flooding at various locations in the study area, with minimal need for additional culvert/oh)e
length. Upsizing culverts should stormwater discharge velocities and should reduce erosion
' risks. However, this alternative would not address streambank erosion problems along stream
channels.
' C. Streambank Stabilization - Alternatives
Stream restoration (natural channel design) was concluded not to be feasible throuqhout the
study area due primarily to urban constraints, including the close proximity of utilities homes
' and other structures to channels in the proiect area. In urban settings where structures are
located within the former floodplain, stream restoration is often not practicable because these
efforts could result in flood damage to existing urban development or could require the relocation
' of existing structures. Urban stream restoration is also often constrained by: 1) insufficient belt
width (needed to restore natural stream meanders), 2) the presence of structures near the top of
streambanks (preventing stream relocation), and 3) buried adjacent utility lines (restricting stream
restoration gradients). Due primarily to these urban constraints, stream restoration was
' determined to be impractical for the proposed proiect. However, stream enhancement was
determined to be feasible, and could provide many of the benefits associated with stream
restoration (e.g., improved aquatic habitat structure diversity, increased baseflow sinuosity,
' improved streambank stability, and increased riparian vegetation).
Extensive riprap/gabion stabilization of streambanks was also considered. This alternative was
determined to be undesirable due largely to the potential for aquatic habitat impacts. The use of
' riprap and/or gabions has permanent impacts to aquatic habitat. However, initial assessments did
indicate that riprap (or other hard stabilization measures) would likely be required at two locations
streambank stabilization locations, due to high anticipated high shear stresses. Further
evaluation indicated that riprap toe protection alone (rather than full streambank armoring) could
' provide the necessary stabilization required at these locations, and could reduce the extent of
potential impacts.
' Overall impact minimization/avoidance measures have included: 1) proposing 'soft' streambank
stabilization measures for the majority of stabilization areas, 2) limiting 'hard' riprap streambank
stabilization to include riprap toe protection only, _3_minimizing culvert replacement extents to the
' minimum length necessary, 4) minimizing riprap apron extents to the minimum widths and
lengths necessary for scour protection, and 5) where practicable, proposing 1,750 If of stream
enhancement, rather than streambank stabilization only.

RECOMMENDED ALTERNATIVES/PROPOSED PROJECT ACTIVITIES
The preferred alternatives for the Columbus Circle / Ashley Park / Westerly Hills CIP's involve a
combination of streambank stabilization (utilizing soil bioengineering/stream enhancement
methods) and culvert replacement.
A. Streambank Stabilization
While each method of streambank stabilization provides positive benefits, neither the exclusive
use of soil bioengineering nor the exclusive use of riprap/gabion/concrete streambank
stabilization was determined to be a feasible option. However, using a combination of `soft'
stabilization measures (soil bioengineering) and limited `hard' stabilization measures (riprap toe
protection) was determined to provide a feasible alternative for streambank stabilization with
minimal impacts. It is anticipated that soil bioengineering will be used where vegetative
stabilization is a feasible option (i.e., where the streambank is shallow and slopes are gradual).
Restoring and improving the stream corridor with vegetation will increase available 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 and hard stabilization are illustrated in Attachment
E.
Stabilization of the eroding streambanks is proposed utilizing a soil bioengineering/stream
enhancement approach. This approach can be implemented despite urban constraints and
should decrease bed and streambank erosion through the combined use `hard' and `soft' soil
bioengineering methods. The land needed for such improvements is minimal, additionally making
this approach appropriate for the proposed project. Urban constraints (e.g., close proximity of
residences) would be a 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 width for appropriate bank slope, and will include
approximately 180 If of perennial stream channel and approximately 720 If of intermittent stream
channel. Final bank slopes will -generally average 2:1, in order to minimize the necessary corridor
width. Soil bioengineerinq techniques to be utilized for this project will include streambank re-
sloping, permanent erosion control matting installation, and seeding.
While soil bioengineerinq is generally the most desirable streambank stabilization method with
regards to aquatic and wildlife habitat, the use of vegetation alone in the study areas is not
feasible due to high anticipated shear stresses along some channel reaches. Along
approximately 169 If of perennial channel, riprap toe protection will be used to help stabilize
streambank areas. The extent of this hard stabilization has been minimized to the extent
necessary for scour protection at these locations. This minimal riprap should provide protection
against excessive shear stress, and should allow for natural revegetation over time.
Additionally, approximately 1,625 If of perennial stream will be enhanced. This effort will be
implemented as an alternative to streambank stabilization, and should provide greater habitat and
water quality benefits. Within the stream enhancement reaches, approximately 45 rock cross
vanes will be installed. These structures should mimic natural bedrock outcrops, should help
increase baseflow stream channel sinuosity, and should reduce shear stresses (erosive forces)
along the adjacent streambanks. While this enhancement is anticipated to provide a variety of
benefit to the stream channel, it is not being proposed for separate mitigation credit. However,
these efforts are anticipated to make the proposed CIP's `self-mitigating.'

B. Maintenance Activities
Culvert maintenance activities, including associated riprap inlet/outlet protection placement, will
be performed in jurisdictional channels at two existing roadway crossing locations. These
replacements should increase conveyance capacity to minimize/eliminate "bottlenecks" at
existing undersized culverts. The new culverts will address "bottlenecks" by lowering upstream
water surface elevations during storm water discharge events and minimizing street/structural
flooding. These maintenance efforts will include replacement of an existing 74 If culvert (72"
corrugated metal pipe) with a new 64 If culvert (8'x8' reinforced concrete box culvert) at Denver
Avenue, and replacement of an existing 101 If culvert structure (60" and 78"reinforced concrete
pipes) at Alleghany Street with a new 120 If culvert (8'x8' reinforced concrete box culvert). The
Alleghany Street culvert replacement will require approximately 19 If of unavoidable perennial
stream impacts (resulting from culvert extension), while the Denver Avenue culvert replacement
will result in 10 If of channel 'daylighting' (due to reduced culvert length). The proposed culvert
replacements may also include replacement of existing inlet/outlet protection riprap. Both
replacement culvert inverts have been designed to be buried approximately one foot below the
existing stream substrate.
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/stream enhancement efforts will be implemented both from the top of streambanks
and within stream channels. Erosion and sediment control measures will be implemented to
reduce the risk of downstream impacts during construction.
Summary
A combination of storm water manaqement measures was determined to be the preferred
alternative for the proposed Columbus Circle / Ashley Park / Westerly Hills CIP's. These storm
drainage improvement measures will include: 1) approximately 900 If of 'soft' soil bioengineering
streambank stabilization (180 If along perennial channel and 720 If along intermittent channel), 2)
' approximately 169 If of 'hard' stabilization along perennial stream, 3) approximately 19 If of culvert
extension along perennial stream, 4) riprap replacement at culvert maintenance/replacement
locations, and 5) approximately 1,625 If of stream enhancement along perennial stream.
Significant efforts have been made to minimize anticipated project impacts, including: 1) use of
'soft' soil bioengineering streambank stabilization, 2) minimization of 'hard' streambank
stabilization to include toe protection only, 3) minimization of culvert replacement lengths ('pipe
for pipe' replacement when practicable), 4) minimization of riprap apron extents, and 5)
implementation of stream enhancement rather than streambank stabilization (where practicable).
Following project completion, CSWS will monitor stability and success of the proposed measures.
CSWS anticipates vegetation monitoring for one year following construction completion.

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/stnngide.html.
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 anticipated that the proposed Columbus Circle / Ashley Park / Westerly Hills Capital
Improvement Proiects will be `self-mitigating.' It is not anticipated that compensatory mitigation
will be required for the proposed `soft' soil bioengineering streambank stabilization measures,
since completion of these activities is expected to result in reduced streambank erosion and
substantial improvements to the aquatic and riparian ecosystem. It is anticipated that the benefits
of the proposed stream enhancement efforts will effectively mitigate for potential impacts
associated with culvert/riprap apron extensions.
Page 12 of 16
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 hqp://h2o.enr.state.nc.us/wip/index.htm. If

COLUMBUS CIRCLE CAPITAL IMPROVEMENT PROJECT
The purpose of the Columbus Circle Capital Improvement Project is to address storm
drainage issues identified from citizen requests. Citizen requests include street flooding,
first floor flooding, crawl space flooding, and stream bank erosion. The initial phase of
the project included a planning study to evaluate the existing conditions of the storm
drainage conveyance systems throughout the project area and make recommendations to
bring undersized drainage features up to current City of Charlotte design standards.
Recommendations- include-upsizing-roadway culverts and pipe systems providing-----_. - --
additional catch basins and inlets to collect surface drainage, and to provide measures for
stabilizing eroding stream banks.
An evaluation of jurisdictional streams was conducted by Carolina Wetland Services as
part of this study. The following table lists the channel designations within the project
limits:

Hydraulic Analysis
Primary Conveyance Systems
The majority of the primary conveyance systems are comprised of closed pipe systems.
The remainder are comprised of short open channel reaches and pipe outfall ditches. The
closed pipe systems were analyzed and designed using HYDRAFLOW storm sewer
modeling software. Peak discharge data was computed in HYDRAFLOW using the
Rational Method. The short stream reaches were analyzed and designed using
FLOWMASTER.
The stream reach that parallels Bristol Drive (Plan Sheets 35-37) was analyzed and
designed using HEC-RAS modeling software developed by the US Army Corps of
Engineers Hydraulic Engineering Center. The HEC-RAS version used for this project
supports one-dimensional steady flow hydraulics. Generally, water surface profiles are
calculated with the standard step method, which sequentially solves the energy equation
between cross sections.
Peak discharge data for the Bristol Drive study was computed using the Rational Method.
- - - - - - - -- -Other input parameters for the HEC-RAS-model are based upon field survey data--field-
investigations, and other model parameters. Field data includes measurements and
observations of culverts, open channels, and other site specific parameters. Specific
measurements and observations for culverts included lengths, inverts, roughness, slope,
size, and shape. Specific measurements and observations for open channels includdd
cross-sectional geometry, reach lengths, slopes, and roughness. In addition, composite
loss coefficients were estimated for culverts to account for expansion, contraction, and
other minor losses.
Bristol Drive Existing Conditions:
The Bristol Drive channel improvements included a study to evaluate flooding
complaints and stream bank erosion. As part of the study a hydraulic analysis was
performed in HEC-RAS to determine existing water surface elevations. A second
hydraulic analysis was performed that included re-graded cross sectional geometry to
lower the water surface elevations. The discharge values inserted into HEC-RAS are
listed in Table 2.

The HEC-RAS analysis shows significant road flooding for the 25-year storm event
along Bristol Drive from Station 1+50 to Station 5+50 and from Station 9+70 to Station
13+00. The Wilson Avenue culvert overtops for the 2-year storm event. Complete
existing conditions HEC-RAS output for the Bristol Drive area can be found in the
Appendix.
Bristol Drive Improvements:
' The Bristol Drive area, in addition to severe flooding, contains a well entrenched,
severely eroding stream that requires significant stabilization measures to ensure the
' protection of the adjacent road (Bristol Drive) from ever becoming undermined. The
proposed channel stabilization improvements consist mainly of the placement of rock
cross-veins to promote in channel stability by forming large, appropriately spaced pools
' to dissipate energy and provide habitat for aquatic organisms and fish. Bankfull benches
are not utilized in this stabilization design because of the constraints placed on the width
of the stream by the adjacent road and terrace.
' In order to determine a representative channel design to convey more frequent storms,
several publications by Rosgen (1994, 1996, and 1997) were consulted. Additionally,
I Doll et al. (2002) was used to determine the appropriate channel dimensions for use on
this project. Table 1 below provides the hydraulic geometry information utilized in the
design of this stream stabilization project:

It should be noted that a full Rosgen analysis was not completed for this project. Values
used for the design of the Bristol Drive stream stabilization were generated from
previously collected reference data from various locations and the relationships utilized
generally follow Rosgen (1994, 1996, and 1997). Vane design followed Rosgen (2001).
Proposed improvements to the Bristol Drive channel include grading banks to 1.5:1 side
slopes, replacing culvert at Station 1+50 (Sheet 35) with a pedestrian bridge, re-routing
channel from Station 14+50 to Station 16+20, and replacing the Wilson Avenue culvert
(part of the Ashley Park Neighborhood Improvement Project). These improvements
greatly reduced the water surface elevation along the channel. Table 5 below lists the
proposed water surface elevation along the Bristol Drive Channel:

The improvements to the channel along Bristol Drive resulted in
a dramatic reduction in
' water surface elevation for all storm events. The improvements will eliminate road
flooding for all storm events. The water surface elevation remains in the bank for the
100-year storm is most places. The proposed Wilson Avenue culvert will offer 100-year
flood protection from overtopping. Complete proposed conditions HEC-RAS output for
the Bristol Drive area can be found in the Appendix.
Other Areas of ChanneYImprovements: ----
Line "A"
The outfall of line "A" includes approximately 45 linear feet of channel grading, brush
removal, and debris removal. Approximately 50 linear feet of rip rap apron and channel
' protection will be constructed downstream of the 6' x 5' concrete box culvert (Structure
Al, Plan Sheet 4) to stabilize the outlet and to replace the existing rip rap channel lining.
Line "F"
Approximately 373 linear feet of existing wet weather ditch (un-important intermittent)
f will be re-graded between Structure F2 (Sheet 16) and Structure F3 (Sheet 17). The
existing ditch is clogged with garbage, appliances, furniture, brush, etc. and suffers from
erosion because of the blockages. Recommendations include debris removal and re-
grading of the channel profile and channel banks. The ditch will be protected with
permanent erosion control matting and vegetation.
I Lines "Q". "R", "S" & "W"
Line "Q" (Sheet 21), Line "R" (Sheet 22), Line "S" (Sheet 23), & Line "W" (Sheet 25)
' are wet weather outfalls draining small street systems. These ditches are not
jurisdictional. Line "Q" proposes re-grading 20 linear feet of outfall ditch (See Detail
Sheet 92) and construction of 10 linear feet of Class I rip rap apron (NCDOT 876.02).
All outfall ditches will be protected with permanent erosion control matting. Line "R"
proposes construction of 10 linear feet of Class I rip rap apron. Line "W" proposes re-
grading 115 linear feet outfall ditch (see Detail Sheet 92) and construction of 10 linear
feet of Class I rip rap apron (NCDOT 876.02).
Line "CD"
Line "CD" (Sheet 28) is a wet weather outfall that drains street systems. Line "CD"
proposes re-grading 40 linear feet of existing outfall ditch (below Line "CE", Sheet 29)
and construction of 10 linear feet of Class I rip rap apron (NCDOT 876.02).
Line "CE"
Line "CE" is a wet weather outfall that drains street systems. Line "CE" proposed re-
grading of 225 linear feet of existing ditch (See Detail Sheet 92) and construction of
Class I rip rap apron.
Line "PA"
Line "PA" is an existing closed pipe system that is being upsized (Sheet 30). Line "PA"
proposes re-grading 50 linear feet of existing outfall ditch (See Detail Sheet 92) and
-construction of 48-linear feet of Class-I-rip-rap apron (NCDOT 876.02)
Denver Avenue / AlleQhanv Street Culvert Reulacement and Channel Gradin
The existing culvert beneath Denver Avenue and Alleghany Street will be replaced with
dual 8' x 8' RCBC. The culvert inverts will be set one foot below the natural channel
bottom. The 78 linear foot stream channel downstream of Headwall DA1 (Sheet 33) will
be graded to accommodate the new box culverts. A portion of the existing channel will
be backf fled once the old culverts are replaced.
Approximately 136 linear feet of stream channel will be re-graded (Sheets 33 & 34)
between DA2 and DA3 to create a smooth channel bend. The stream channel will be
stabilized with toe rip rap protection along the outside bend of the stream and all newly
graded stream banks will be stabilized with permanent erosion control matting.
Approximately 45 linear feet of stream channel will be re-graded (Sheet 34) upstream of
Headwall DA6 in order to tie-in the new wing walls to the existing stream channel.

Dear Mr. Cantrell:
Charlotte Storm Water Services (CSWS) has retained MACTEC Engineering and Consulting, Inc.
' (MACTEC) to provide environmental services for the subject capital improvement project (CIP). It is our
understanding that this project may require Clean Water Act (Section 404) permitting. On behalf of
CSWS, we are hereby contacting the U.S. Fish and Wildlife Service (USFWS) regarding the potential
presence of federally protected species within the study area that may be affected by the proposed project.
We request 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,
The study area includes portions of the Taggart Creek watershed and the Stewart Creek watershed. As
indicated on Figure 1, the study area is generally bordered by Freedom Drive to the northeast, Wilkinson.
Boulevard to the south, and Interstate I-85 to the northwest. The study area includes the Westerly Hills
and Ashley Park neighborhoods. Waters of the U.S. located within the watersheds include unnamed
tributaries to Taggart Creek and unnamed tributaries to Stewart Creek. The study area contains
approximately 14,500 linear feet (If) of open stream channel with surrounding land use that is
predominantly residential. Anticipated project activities may include pipe and culvert replacements,
along with channel improvements. A planning study is currently underway and will assess culvert
replacement needs, closed pipe system and inlet capacities, natural channel design, utility conflicts,
potential detention sites, and elevating (or flood-proofing) flood-prone structures. The USGS 7.5-minute
topographic map that covers the project area is Charlotte West, North Carolina (1993).

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