Tyvola Drive Storm Drainage Improvement Project May 10, 2005
Nationwide Permit Nos. 3 and 27 Application CWS Project No. 2003-0452:2
Executive Summary
The Tyvola Drive Storm Drainage Improvement Project is bordered to the northeast by Kentland
Lane, to the southeast by Londonberry Road, and to the west by the Norfolk-Southern Railroad line
located between South Boulevard and Old Pineville Road in Charlotte, North Carolina
(Attachment A - Figure 1). This project is associated with the proposed South Corridor light rail
line. The purposes of the proposed channel enhancement, stabilization, and maintenance activities
are to upgrade the existing stormwater infrastructure to current City standards and improve overall
water quality. This project is US Infrastructure of Carolina, Inc. (USI) and Charlotte Storm Water
Services (CSWS) contracted Carolina Wetland Services, Inc. (CWS) to provide Section 404/401
(of the Clean Water act) permitting services for this project.
The results of the on-site field investigation conducted by CWS indicate that there are three
potential jurisdictional streams (Streams A, B, and D) and two non jurisdictional channels
(Channels C and E) located within the project corridor (Attachment A - Figure 3).
Based on the results of a Stream Assessment prepared by Buck Engineering, portions of on-site
streams would benefit from the installation of bank stabilization, grade controls, in-stream habitat
structures, and floodplain benches (Attachment I). This project proposes the restoration and/or
enhancement of approximately 930 linear feet (10 of perennial stream channel under Nationwide
Permit No. 27 (Attachment J). In addition, CSWS proposes approximately 138 linear feet of rip rap
replacement, 135 linear feet of apron replacement and plunge pool creation, and approximately 15
linear feet of culvert extension under Nationwide Permit No. 3 (Attachment J).
On behalf of CSWS, CWS is submitting a Pre-Construction Notification with attachments in
accordance with Nationwide Permit General Condition No. 13, and pursuant to Nationwide Permit
Nos. 3 and 27 (Attachment B). CWS is requesting written verification from the U.S. Army Corps
of Engineers of the extent of jurisdictional features on the subject project (Attachment Q.

Tyvola Drive Storm Drainage Improvement Project May 10, 2005
Nationwide Permit Nos. 3 and 27 Application CWS Project No. 2003-0452:2
Existing Conditions
The Tyvola Drive Storm Drainage Improvement Project is bordered to the northeast by Kentland
Lane, to the southeast by Londonberry Road, and to the west by the Norfolk-Southern Railroad line
located between South Boulevard and Old Pineville Road in Charlotte, North Carolina
(Attachment A - Figure 1). The purposes of the proposed channel enhancement, stabilization, and
maintenance activities are to improve overall water quality and ecological function of on-site
stream channels, reduce erosion, and repair stormwater infrastructure. US Infrastructure of
Carolina, Inc. (USI) and Charlotte Storm Water Services (CSWS) contracted Carolina Wetland
Services, Inc. (CWS) to provide 404/401 permitting services for this project.
Current Land Use
The current land use for the project area is commercial and residential and is comprised of parking
lots, railroads, maintained lawns, driveways, and adjacent wooded areas. Dominant vegetation
within the project area consists of sweet gum (Liquidambar styracijlua), Japanese honeysuckle
(Lonicera japonica), red oak (Quercus rubra), and willow oak (Quercus phellos). According to
the Soil Survey of Mecklenburg County', on-site soils consist of Cecil sandy clay loams
(CeB2 and CeD2), Cecil-Urban land complex (CuB, and CuD), and Urban land (Ur)
(Attachment A - Figure 2). Cecil soils are typically found in upland areas and along slopes, are
well drained and have moderate permeability.
Jurisdictional Delineation
On December 2, 2003, and April 1, 2004, CWS's Isaac Hinson and Ron Johnson, WPIT delineated
potential on-site jurisdictional waters of the U.S.z within the project corridor using the U.S. Army
Corps of Engineers (USACE) Routine On-Site Determination Method. This method is defined in
the 1987 Corps of Engineers Wetlands Delineation Manual.3 No wetland areas were observed
within the project limits. A Routine On-Site Data Form representative of non jurisdictional upland
areas has been included (Attachment D). Jurisdictional waters of the U.S. were classified

according to recent North Carolina Division of Water Quality (NCDWQ)4 and USACE guidance.
NCDWQ Stream Classification Forms and USACE Stream Quality Assessment Worksheets
representative of the on-site streams and non jurisdictional channels have been included
(Attachments E and F).
The results of the on-site field investigation conducted by CWS indicate that there are three
potentially jurisdictional streams (Streams A, B, and D) and two non jurisdictional channels
(Channels C and E) located within the project corridor (Attachment A - Figure 3). On-Site
potential jurisdictional waters are unnamed tributaries to Little Sugar Creek within the Catawba
River basin (HU# 030501035) and rated "Class C Waters" by the NCDWQ.
Stream A flows southeast across the project area for approximately 1,300 linear feet
(Attachment A - Figure 3). Stream A was evaluated to be Perennial and exhibits moderate flow
and sinuosity with a 6 to 12-foot bankfull width. Crayfish, benthic macroinvertebrates, and algae
were observed on the day of the field investigation. This stream channel scored 38 points out of a
possible 71 points on the NCDWQ Stream Classification Form and 50 points out of a possible 100
points on the USACE Stream Quality Assessment Worksheet (Attachments E and F - SCP1).
Photographs of Perennial Stream A have been included (Attachment G - Photographs A and B).
Stream B generally flows east across the project area and includes piped portions. Open (unpiped)
portions of Stream B are approximately 240 linear feet in length (Attachment A - Figure 3).
Stream B was evaluated to be Perennial and exhibits moderate flow, a 4-foot bankfull width, and a
weak presence of crayfish. Stream B scored 26 points out of a possible 71 points on the NCDWQ
Stream Classification Form and 38 points out of a possible 100 points on the USACE Stream
Quality Assessment Worksheet (Attachments E and F - SCP2). A photograph of Perennial Stream
B has been included (Attachment G - Photograph C).
Channel C is approximately 30 linear feet in length and is located in the eastern portion of the
project area (Attachment A - Figure 3). Channel C is contiguous with Perennial Stream A and was
determined to be non jurisdictional because it is a man-made feature that drains a largely

impervious area adjacent to an apartment complex. This channel lacks sinuosity, biological
indicators, and topography indicative of natural drainage features (Attachments E and F - SCP3).
This stream channel scored 14.5 points out of a possible 71 points on the NCDWQ Stream
Classification Form and 35 points out of a possible 100 points on the USACE Stream Quality
Assessment Worksheet. A photograph of Non-Jurisdictional Channel C has been included
(Attachment G - Photograph D).
Unimportant Intermittent Stream D is located along the west project limit and flows south for
approximately 200 linear feet (Attachment A - Figure 3). This stream exhibits a 2 to 3-foot
average bankfull width, weak sinuosity, channel substrate consisting of coarse sand to cobble, and
moderately eroded banks (Attachments E and F - SCP5). Benthic macroinvertebrates (chironomid
and mosquito larva) were sampled from the channel on the day of the fieldwork resulting in a
"weak" rating. Unimportant Intermittent Stream E scored 21.5 out of a possible 71 points on the
NCDWQ Stream Classification Form and 28 out of a possible 100 points on the USACE Stream
Quality Assessment Worksheet. A photograph of the Unimportant Intermittent portion of Stream E
has been included (Attachment G - Photograph E).
The Unimportant Intermittent portion of this channel is fed by an approximately 250 linear-foot
non jurisdictional channel to the north, and joins an approximately 500 linear-foot non-
jurisdictional channel from the south at a pipe inlet (Attachment A - Figure 3). Jointly, the two
non jurisdictional channel segments comprise Non-Jurisdictional Channel E. Channel E lacks
sinuosity, the presence of benthic macro invertebrates, and other biological indicators
(Attachments E and F - SCP4 and SCP6). This channel has a moderate presence of plants in the
streambed. The two channel segments were evaluated independently and both scored 9 out of a
possible 71 points on the NCDWQ Stream Classification Form and 24 out of a possible 100 points
on the USACE Stream Quality Assessment Worksheet. Photographs of Non-Jurisdictional
Channel E are included (Attachment G - Photographs F, G, and H).

Agency Correspondence
Cultural Resources
A letter was forwarded to the State Historic Preservation Office (SHPO) on January 3, 2005
requesting a determination of the presence of any areas of architectural, historic, or archaeological
significance that would be affected by the project. A response from SHPO was received on
January 14, 2005, indicating that no known cultural or historic resources would be affected by this
project (Attachment H).
Protected Species
A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on
January 3, 2005 requesting a determination of the presence of any known federally-listed,
candidate endangered, threatened species or critical habitat located within the project area. A
response from NCNHP was received on January 4, 2005, indicating that no element occurrences
have been documented within a mile of this site (Attachment H).
Purpose and Need for the Project
The Tyvola Drive Storm Drainage Improvement Project is associated with the proposed South
Corridor light rail line. The purposes of the proposed channel enhancement, stabilization, and
maintenance activities are to upgrade the existing stormwater system to current City standards and
improve overall water quality. The results of a Stream Assessment prepared by Buck Engineering
indicate that Streams A and B would benefit from bank stabilization and the installation of grade
controls, in-stream habitat structures, and floodplain benches. Due to the urban nature of the
channels and multiple site constraints, conventional Priority I restoration is not a feasible option.
Therefore, a modified Rosgen design is being proposed that meets the project's goals and improves
water quality.
Avoidance and Minimization
Impacts to on-site jurisdictional waters have been minimized to the extent practicable. The project
design has also limited the length of culvert placement to the minimum length necessary according
to current City design standards. Proper sediment and erosion control measures will be used to

minimize disturbances to downstream waters. Aside from habitat-enhancing in-stream structures
and floodplain benching, hard stabilization will be installed in areas that require velocity control
and structure protection. Table 1 provides the shear stress calculations that were used to specify
the proposed type of stabilization. Please note that shear stress values are only presented for
straight channel sections. Shear stress values for the outside of meander bends are assumed to be
greater. Table 2 shows the allowable shear stress for different materials. More shear stress details
are available in Attachment I.

areas that require additional stabilization due to channel velocities. Appropriate sediment and
erosion control practices that are outlined in the most recent version of the "North Carolina Erosion
and Sediment Control Planning and Design Manual" will be designed and installed, and maintained
properly to assure compliance with the appropriate turbidity water quality standard (50 NTUs in
streams not designated as trout waters by NCDWQ). Sediment and erosion control measures
placed in stream channels will be removed and the natural grade restored after construction
completion. Trees and shrubs outside of the easement limits, in addition to those that receive
tree/shrub protection barriers, will be protected.
Proposed Impacts to jurisdictional Waters
On behalf of CSWS, CWS is submitting a Pre-Construction Notification application with
attachments in accordance with Nationwide Permit General Condition No. 13, and pursuant to
Nationwide Permit Nos. 3 and 27. Nationwide Permit No. 3 allows for the maintenance of any
previously authorized structure or fill. Nationwide Permit No. 27 allows for restoration and
enhancement of jurisdictional areas. The proposed construction plans and details are included as
Attachment J. Table 3 summarizes the proposed activities in jurisdictional stream channels.

Tyvola Drive Storm Drainage Improvement Project May 10, 2005
Nationwide Permit Nos. 3 and 27 Application CWS Project No. 2003-0452:2
Nationwide Permit No. 3
Proposed impacts under Nationwide Permit No. 3 include the replacement of approximately 65 if
of rip rap aprons and the creation of two plunge pool areas at culvert outfalls (70 if total) along
perennial Streams A and B (Table 3). In addition, approximately 138 if of rip rap will be replaced
within Unimportant Intermittent Stream D. A culvert crossing under Tyvola Drive is being
replaced with a box culvert that includes an additional 15 if of pipe. The culvert replacement under
Tyvola Drive will be buried in accordance with standard permit conditions.
Nationwide Permit No. 27
Proposed activities to be conducted under Nationwide Permit No. 27 include the enhancement of
approximately 9301f of Perennial Streams A and B. A rip rap toe is proposed for approximately
155 linear feet (310 bf) of these channels due to velocity requirements. In addition, approximately
235 if of constructed riffles are proposed to provide in-stream habitat and stabilization. Please note
that these sections at Streams A and B were previously lined with rip rap and the proposed rip rap
only represents a temporary impact from its replacement. The proposed design will utilize
floodplain benches along approximately 7001f to increase floodplain access. Bioengineering is
being proposed along the restored channel segments. At this time, the City of Charlotte is not
requesting mitigation credits for this work.
Compensatory Mitigation
The proposed activities will result in an overall benefit to the water quality of downstream waters by
improving in-stream habitat, reducing bank erosion, and upgrading stormwater infrastructure.
Because of the anticipated environmental benefits of the project, no additional mitigation is
proposed for the Tyvola Drive Storm Drainage Improvement Project.

VII. Impact Justification (Avoidance and Minimization)
Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent
practicable. The protect design has also limited the length of culvert placement to the minimum
length necessary and according to current City design standards. Proper sediment and erosion control
measures will be used to minimize disturbances to downstream waters. Aside from habitat-enhancing
in-stream structures and floodplain benching, hard stabilization will be installed in areas that require
velocity control and structure protection. Where utilized, rip rap will only be placed along the toe of
the slope along perennial stream segments. Soft stabilization (i.e. erosion control matting, live stakes,
shrubs, etc.) will be installed to stabilize upper channel banks. Please note that the majority of
Streams A and B have been stabilized with rip rap in the past. The proposed plan will only use rip
rap along outside meander bends and areas that require additional stabilization due to channel
velocities. Appropriate sediment and erosion control practices that are outlined in the most recent
version of "North Carolina Erosion and Sediment Control Planning and Design Manual" will be
designed and installed, and maintained properly to assure compliance with the appropriate turbidity
water quality standard (50 NTUs in streams not designated as trout waters by NCDWQ). All
sediment and erosion control measures placed in stream channels will be removed and the natural
grade restored after construction completion. All trees and shrubs outside of the easement limits, in
addition to those that receive tree/shrub protection barriers, will be protected.

VIII. Mitigation
The proposed activities will result in an overall benefit to the water quality of downstream waters by
improving in-stream habitat, reducing bank erosion, and upgrading stormwater infrastructure. Because
of the anticipated environmental benefits of the project, no additional mitigation is proposed for the
Tyvola Drive Storm Drainage Improvement Project.
1. 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

Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.

Instructions for completion of workslieet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, ctc. Every characteristic must be scored using the same ecoregion. Assign points to each
characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the
worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a characteristic cannot be evaluated due to site or
weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character
of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more

Introduction
1.1 Purpose
Buck Engineering (Buck) was tasked with providing assessments of stream corridor
conditions and restoration or enhancement potential for the following four basins along the
South Transit Corridor in Charlotte: Basin 5 (Conway/Briabend), Basin 6 (Peterson), Basin
11 (Tyvola) and Basin 13 (Edgewater/Rosecrest).
This report summarizes our assessment and recommendations for Basin 11, the Tyvola Drive
Storm Drainage System. The report briefly summarizes project objectives, provides an
overview of the basin, discusses the assessment methodology, summarizes assessment
results, and provides recommendations and evaluations for restoration or enhancement for
mitigation.
1.2 Objectives
The objectives of the stream assessment work were to:
• Document existing geomorphic conditions;
• Assess the stream's departure from stability and causes of instability;
• Evaluate design and construction constraints with respect to stream restoration or
enhancement; and
• Develop recommendations for mitigation credit potential.
1.3 Basin Overview
The Tyvola Drive Storm Drainage System is located about five miles southwest of downtown
Charlotte. The drainage system originates in a pipe on the west side of South Boulevard and
flows generally east through pipe and open channel to a culvert beneath Tyvola Drive. The
system then flows as an open channel southeast toward a culvert beneath Londonderry Road.
Culverts also exist downstream at the Seacroft, Burnley and Farmbrook crossings. The
section of the system below Farmbrook flows as primarily an open channel to its confluence
with Little Sugar Creek.
The drainage area at the confluence with Little Sugar Creek is approximately 520 acres.
Land use at the upland end of the watershed is mixed commercial, industrial and residential.
Land use over the lower end of the watershed is primarily single family residential.
1.4 Supporting Data
Supporting data are provided in the Appendix and include the following:
• Vicinity map of delineated project sub-reaches, Figures 1 and 2;
• Comprehensive summary assessment data matrix, Table 1;
• Existing condition parameter summary table per sub-reach;

1.5 Stream Mitigation Terminology
Paraphrasing from the US Army Corps of Engineers "Stream Mitigation Guidelines" dated
April 2003:
Restoration - the process of converting an unstable, altered or degraded stream
corridor, including adjacent buffers and flood prone areas, to its natural stable
condition. Restoration is based on reference conditions and includes restoring the
appropriate channel dimension, pattern and profile. For impacts to fair or poor
quality waters, the mitigation credit ratio is generally 1.0 (i.e. for every 100 feet of
stream impact, 100 feet of stream restoration would be required for mitigation).
Enhancement Level I - mitigation category that includes improvements to the stream
channel and riparian zone that restore dimension and profile, but do not address
pattern. The mitigation credit ratio ranges from 1.0 to 1.5 (i.e. 100 to 150 feet of
Enhancement Level I required for every 100 feet of impact).
Enhancement Level II - mitigation category for measures that improve channel
stability, water quality and habitat, but fall short of restoring both dimension and
profile. Examples include bank stabilization, vegetating riparian buffers and using
in-stream structures to enhance stability and habitat. The mitigation credit ratio
ranges from 1.5 to 2.5.
2 Methodology
2.1 Sub-reach Delineation
The Tyvola Drive Storm Drainage System was divided into seven sub-reaches (as illustrated
on Figures 1 and 2) that were delineated based on stream conditions and road crossings.
Dividing the geomorphic surveys by sub-reach allows a more detailed and discrete
assessment of existing stream conditions and site constraints.
2.2 Data Collection
Existing condition surveys performed for each sub-reach consisted of the following
components:
Partial longitudinal survey;
Cross section surveys;
Substrate samples (pebble count and pavement/subpavement);
Basin 11 (Tyvola Drive) Stream Assessments
Buck Project No. 0176C
US Infrastructure of Carolina
December 23, 2004
Page 2 of 8
• Riparian vegetation inventory; and
• Modified Pfankuch channel stability evaluation.
Locations of the geomorphic survey components and substrate samples listed above are
depicted on Figures 1 and 2. Riparian vegetation and channel stability were evaluated
throughout the entire length of each sub-reach.
Geomorphic data were used to generate Rosgen Level II stream classifications (describing
stream type and substrate materials) for each sub-reach. Qualitative observations of channel
stability, along with the geomorphic data, provide insight into the current evolutionary state
and projected continued evolution of each sub-reach. Attention was also directed toward
design/construction constraints, potential mitigation credit, and water quality permitting
issues as significant factors influencing the potential for restoration and enhancement.
The existing conditions for each sub-reach are presented in Table 1. Table 1 integrates the
assessment data into a comprehensive summary categorizing stream classification, present
geomorphic and biological conditions, design/construction constraints, and potential
mitigation credit per sub-reach.
2.3 Bankfull Verification
Bankfull cross sectional areas measured from surveyed riffles were compared to the North
Carolina piedmont regional curve to verify field identification of bankfull stage. The
regional curve is a compilation of cross sectional survey data at sites across the North
Carolina piedmont that relates drainage area to channel cross sectional area. Urban and rural
data are presented as separate regression lines because impacted urban watersheds have been
shown to lead to channel enlargement.
At the Tyvola sites, bankfull indicators in the field included upper scour lines, back of
depositional benches, and significant breaks in slope. Bankf ill stage in impacted reaches is
seldom coincident with the top of bank. Figure 3 shows riffle cross sectional areas at the
project sub-reaches superimposed on the urban and rural piedmont regional curves. With the
exception of the sub-reach C section, the surveyed cross sectional areas from all sub-reaches
plot between the urban and rural curve data, indicating that channel enlargement has occurred
in response to the urban influence on watershed hydrology. The relatively minimal
enlargement, as compared to the urban curve data, may be explained by bedrock outcrops
that have prevented large-scale channel incision. The relatively small cross sectional area for
sub-reach C is likely due to riprap armoring and the way that the riprap prevents channel
adjustment.

3 Summary of Results
3.1 Sub-reach A
Geomorphic and Stability Assessment
The Level II stream classification for this sub-reach was identified as G5/3c. The dual
classification refers to a bimodal substrate distribution; sections of the sub-reach have a
gravel/cobble bed and some have a sand/clay bed. The gravel/cobble bed sections appear to
have been stabilized with riprap. Organic and inorganic debris is present throughout the
reach, both in the stream and on the banks.
The sub-reach is horizontally unstable throughout and vertically unstable in the clay bed
sections. Severe bank erosion is evident in several locations. Active incision is apparent in
some of the sand/clay bed sections, although riprap stabilization efforts have checked channel
incision to some extent. With further incision limited, stress on the banks has increased as
the channel adjusts to new slope constraints and hydrologic conditions. Left unchecked, this
lateral erosion process is likely to continue for years. The Pfankuch channel stability
evaluation rating for this sub-reach was poor. The pavement D50 (43 mm) is coarser than the
subpavement D50 (12 mm), indicating a somewhat stable bed at the sample location.
The causes for the observed instability are likely both localized and system wide. On the
local scale, channel straightening and the loss of riparian buffers has led to channel incision,
increased stress on the banks and the loss of stabilizing vegetative root mass. At the larger
watershed scale, an increase in impervious area has changed hydrology such that the channels
are exposed to increased flood peaks and frequency. Floodplain filling has also likely
contributed to channel instability; the channel has less frequent access to its historic
floodplain.
Constraints and Mitigation Potential
Mitigation opportunities are relatively good for sub-reach A. As indicated on the data matrix,
sub-reach A is likely appropriate for restoration or Level I enhancement. Stream dimension,
pattern and profile could potentially all be addressed, and riparian buffers could be
established or preserved on both banks. Constraints are numerous but do not necessarily
preclude restoration. Key constraints include:
• Apartment buildings as close as 20 feet from the left top of bank;
• Two storm drain outfalls on the left bank;
• Culverts at the upstream and downstream ends;
• Fences at property lines;
• Mature trees, particularly on the right bank.
Sub-reach A does have space on the right bank to construct a floodplain bench or establish
new pattern. Bench or channel excavations would extend into a hill slope, increasing
earthwork costs somewhat. The majority of the reach is contained within a single parcel.

Buck Project No. 0176C December 23, 2004
Page 4 of 8 1
There is the potential for an expansion of the restoration effort upstream along a tributary for
approximately 1,000 linear feet. The tributary runs through a wooded parcel between Tyvola
Drive and Flagstaff Drive. The USGS topographic map of the area does not show this
tributary as a "blue line" or perennial stream, but there was baseflow in the channel the last
time we visited the site, which was several days after a rainfall event. Further investigation
as to the perennial or intermittent nature of the stream may be worth pursuing with the Corps
of Engineers or Division of Water Quality.
3.2 Sub-reach B
Geomorphic and Stability Assessment
This short, riprap-lined channel defies classification in the Rosgen Level II scheme because it
is not free to adjust form through natural geomorphic processes. Data from the cross section
and profile surveys suggest the stream is functioning like a G3 stream type in the riprap
section and a G5 stream type in a short section near the downstream end where the riprap
ends.
The right bank is very steep and shows signs of mass wasting and active erosion. The left
bank is relatively stable, mainly because the bank height and angle are much lower than the
right bank. Bank vegetation consists of widely spaced mature hardwoods with an understory
of shrubs and invasive privet and greenbrier.
The bed is essentially stable due to the presence of riprap. Some localized bed erosion was
observed near the downstream end of the sub-reach, where the riprap ends. Incision has been
limited not only by the riprap, but also by culverts at the upstream and downstream ends.
The Pfankuch channel stability rating for sub-reach B is good, although this is misleading
because the channel is not free to adjust naturally.
Constraints and Mitigation Potential
Mitigation options are limited for sub-reach B. Site constraints include:
• Culverts at upstream and downstream ends;
• Steep hill slope on right bank;
• Mature trees, mainly on right bank;
• Apartment buildings near the top of both banks.
The right bank is in need of stabilization and a bank stabilization effort using native plant
materials may qualify as enhancement Level II at a low ratio such as 2.5:1. Bank re-grading
options are limited by the presence of the steep hill slope. Stabilization would likely involve
minor bank sloping in conjunction with installation of live stakes and/or brush mattresses.

Buck Project No. 0176C December 23, 2004
Page 5 of 8
3.3 Sub-reach C
Geomorphic and Stability Assessment
As with sub-reach B, this short, riprap-lined channel defies classification in the Rosgen Level
II scheme because it is not free to adjust form through natural geomorphic processes. Data
from the cross section and profile surveys suggest the stream is functioning like a G4c stream
type, even though the entrenchment ratio (2.0) is higher than the typical ratio for a G stream
(less than 1.4). The profile is characterized by long, stagnant runs punctuated by short steps.
Both banks are very high relative to the bankf ill stage, but they are relatively stable due to
the presence of riprap and concrete rubble slope protection. Localized bank erosion was
noted in a few locations. Like the banks, the bed is stable due to the presence of riprap. The
Pfankuch channel stability rating for sub-reach C is good, although this is misleading because
G channels are inherently unstable. The fact that the channel is not free to adjust naturally
also diminishes the meaning of the Pfankuch rating.
Bank vegetation consists of widely spaced mature hardwoods with an understory of shrubs
and invasive privet, and greenbrier.
Constraints and Mitigation Potential
Mitigation options are limited for sub-reach C by the following site constraints:
• Culvert at the upstream end;
• Multiple property owners;
• Mature trees and fences along the tops of both banks; and
• Sanitary sewer and a storm drain outfall on the left bank.
This sub-reach could benefit from 10-foot wide bankfull benches on both banks, in-stream
structures to create more well-defined riffles and pools, and establishment of native riparian
buffers. In order to be effective, this benching/buffer would need to be continuous and would
therefore require permanent easements from each of the property owners. If the benching
and buffer work could be achieved, this sub-reach would likely qualify as enhancement Level
I at a ratio of 1.5:1. However, given the sewer and property constraints, this sub-reach does
not offer promising mitigation opportunities. Stabilization of localized eroding banks is
likely to only feasible approach and is not likely to gain any stream mitigation credit.
3.4 Sub-reaches D and E
The Level II stream classification for these two sub-reaches was identified as G4c. The
majority of these sub-reaches are horizontally unstable, with active bank erosion observed on
both banks. The right bank in sub-reach D has been armored with concrete cylinders and
intermittent riprap. Vertical incision of the channel bed appears to have been halted by
Basin 11 (Tyvola Drive) Stream Assessments US Infrastructure of Carolina
Buck Project No. 0176C December 23, 2004
Page 6 of 8
downstream bedrock and sewer crossings, and culverts at Burnley Road and Farmbrook
Drive. With further incision limited, stress on the banks has increased as the channel adjusts
to new slope constraints and hydrologic conditions. Left unchecked, this lateral erosion
process is likely to continue for years. The Pfankuch channel stability evaluation rating was
fair for sub-reach D and good for sub-reach E, but, as discussed earlier, G channels are
inherently unstable.
Bank vegetation includes a few mature hardwoods and pines, but invasive species are
common. A large stand of bamboo is present over much of the right bank and privet and
English ivy are common in the understory. The lower banks immediately upstream and
downstream of the Burnley Road culvert appear to have been planted with willow and river
birch trees.
Constraints and Mitigation Potential
Mitigation opportunities for sub-reaches D and E are limited by constraints similar to those
present within sub-reach C. Key constraints include:
• Sanitary sewer on the right bank and crossings at the channel bed;
• Storm drain outfalls;
• Multiple property owners;
• Mature trees at the top of bank; and
• Sheds and fences along the top of bank.
As with sub-reach C, benching, in-stream structures and buffer planting would help these
sub-reaches. However, the constraints would likely make a comprehensive mitigation
approach difficult to implement. A bank stabilization effort with little or no stream
mitigation credit is likely the only feasible approach.
3.5 Sub-reaches F and G
Geomorphic and Stability Assessment
The Level Il stream classification for sub-reaches F and G was identified as G3/4c. The
substrate varies significantly through these sub-reaches, with many gravel/sand bed sections
and many bedrock or cobble bed sections. Widespread channel incision to bedrock appears
to be complete and the channel is generally stable vertically. Horizontal instability is the
primary concern for both sub-reaches. Active bank erosion is evident in several locations,
particularly at the outside of meander bends. Left unchecked, this lateral erosion process is
likely to continue for years. The Pfankuch channel stability evaluation rating for these sub-
reaches was good, owning mainly to frequent bedrock in the banks and at the bed. As noted
above, G channels are inherently unstable so the "good" rating is misleading.
The left bank and floodplain has a wide, intact mature buffer. A cleared sanitary sewer
easement passes along sections of the left floodplain. Understory invasive species such as
privet, English ivy and multiflora rose are common but not dominant. The right bank passes
Basin 11 (Tyvola Drive) Stream Assessments US Infrastructure of Carolina
Buck Project No. 0176C December 23, 2004
Page 7 of 8
along several backyards and the buffer, comprised of matures hardwoods and invasive
understory plants, is generally narrow.
Constraints and Mitigation Potential
Constraints are numerous but do not necessarily preclude enhancement. Key constraints
include:
Multiple properties and fences on the right bank;
Storm drain outfalls on both banks;
Sanitary sewer on alternating banks and multiple sewer crossings; and
• Mature trees, particularly on the left bank.
Mitigation opportunities are relatively good for sub-reaches F and G. A Level I enhancement
approach consisting of floodplain benching, in-stream structures and buffer planting appears
feasible in both sub-reaches. Even though benching is likely feasible on only one bank,
typically the left bank, the mitigation credit ratio is likely to be as high as 1.5:1.
4 Mitigation Potential Summary
Good mitigation opportunities exist within the Tyvola Drive Storm Drainage System. Sub-
reach A has the potential for nearly 1,000 linear feet of stream credit, with a possible
doubling of that length along the upstream tributary. Sub-reach B offers a modest mitigation
opportunity, on the order of 50 feet. The highly unstable right bank on sub-reach B is in need
of stabilization, which should be pursued if storm drainage improvements are planned for this
system. Sub-reaches C, D and E offer less mitigation potential due to site constraints and
multiple property owners. Mitigation opportunities do exist on sub-reaches F and G, with the
potential for nearly 2,300 linear feet of stream credit.
For general planning purposes, the approximate dimensions of a restored channel cross
section would be as follows:
Sub-reach Bankfull Width ft Mean Depth ft Bankfull Area (ft)
A and B 12 1.1 13.2
F and G 20 1.5 30
As presented earlier, mitigation credit depends on the level of restoration or enhancement
performed. Table 1 provides estimates of mitigation credit for the various sub-reaches based
on our assessment of constraints and restoration or enhancement scenarios. Mitigation credit
ratios are determined by the Corps of Engineers and the North Carolina Division of Water
Quality on a case-by-case basis. Joining several small projects into a larger, watershed scale
project often earns greater mitigation credit than the sum of individual, disconnected projects.

* Due to the low sinuosity, pattern data cannot accurately be calculated. Any
data calculated would overestimate pattern.
** Sinuosity and valley slope are based on plan form mapping rather than
slopes since the profile was not continuous over the entire reach.
*** Note that water surface slope data is reported for a partial profile survey.

Bankfull Width, Wbkf (ft) 12
Bankfull Mean Depth, Dbkf (ft) 0.9
Design channel slope (ft/ft) 0.0051
Boundary/Bankfull Shear Stress, t (lb/sq ft) 0.25
d50 100 ct/pavement (mm) 46
d50 (mm) - bar sample/sub pavement 14
ratio - d5Opavement/d5Osubpavement 3.29

D100 subpavement (mm) 50
Critical Depth, Dcrit (ft) 1.6
Critical Slope, Scrit 0.00881
Largest moveable particle (Shields/CO curves) 15-65 mm
The design slope is less than the critical slope, and the design depth is less than the
critical depth, indicating a potentially aggradational reach. However, the boundary shear stress
is large enough to move the largest pavement sample.
Given the expected low sediment yield from the watershed and the boundary shear stress estimate,
aggradation does not appear to be a significant concern for the design reach.
