This letter is in reference to PTR'S stream mitigation site located in Forsythe County, North Carolina.
Mitchell & Associates, on behalf of PTR, has previously submitted a mitigation plan for impacts
associated with Leak Fork Creek and its unnamed tributary. Part of this plan included benthic
macroinvertebrate monitoring. Mitchell & Associates obtained Environmental Services, Inc., to
perform this monitoring. Attached are the results of Environmental Services first samplings takenat the
site and at the two reference reaches, and all relevant data associated with these samples. If you
have any further questions, please feel free to give our office a call. Thank you for your time and

RE: Benthic Data Collection, Leak Fork Creek, Winston-Salem, NC ERO1-146
Dear Ms. Burbank:
Thank you for contacting Environmental Services, Inc., (ESI) concerning the above
referenced project. At your request, we have conducted four individual Qual 4 benthic
macro invertebrate collections, as outlined by the North Carolina Division of Water
Quality (NCDWQ), in reaches of Leak Fork Creek. The benthic macro invertebrate
collection sites are located at Patterson Avenue, in the city of Winston-Salem, Forsyth
County, North Carolina. This letter summarizes our findings.
Sampling Methodology
ESI performed the four individual Qual 4 benthic macro invertebrate collections at the
stations on reaches of Leak Fork Creek as identified on mapping provided to ESI (map
attached).
Qual 4 collection technique is utilized on small streams (<I.0 square mile catchment size)
in which all organisms present in a sample are collected for identification. Qual 4
technique calls for 4 individual collections to be performed and include: kick net, sweep
net, leaf-pack, and visual samples.
Kick net sample is performed by standing the net upright on the streambed, while the area
upstream is physically disrupted. The debris and organisms in the kick net are then
washed down into a seive bucket and strained. The sweep net sample is conducted by
disturbing an area of the streambed and then vigorously sweeping through the disturbed
area. Sweeps are usually taken from ban areas, including mud banks and root masses,
and macrophyte beds. Leaf-pack samples consist of washing leaves, sticks, and small
logs through a sieve and sorting the organisms left in the sieve screen. Visual inspection
of large rocks and logs (the larger the better) often adds to the species list. Large rocks
and logs are preferred microhabitat because of their stability during floods.
ENVIRONMENTAL SERVICES, INC.
Ms. Burbank

Page 2 of 3
The four sampling stations consist of Samples #2 and #4 collected in Leak Fork Creek
downstream from the building site, Sample 1 collected in Leak Fork Creek upstream
from the building site and Sample 3 collected in a tributary to Leak Fork Creek upstream
from the building site. Samples 1 and 3 represent reference reaches.
Mr. Eric L. Renninger conducted the Qual 4 collections on 20 November 2001. Mr.
Renninger is a project scientist with a B.S. degree in Wildlife and Fisheries Science with
more than 2 years of professional experience. Mr. Renninger has successfully completed
NCDWQ Aquatic Insect Collection Protocols Workshop for Stream Mitigation and
Restoration, and advanced training coursework (Biology and Identification of
Southeastern Mayfly, Stonefly, and Caddisfly Larvae) through UNC Chapel Hill at
Highlands Biological Station, Highlands, NC.
invertebrate Identification
ESI contracted the laboratory services of Pennington and Associates, Cookeville,
Tennessee, for the identification of all macroinvertebrates collected from the 4 locations
on Leak Fork Creek. Pennington and Associates Inc., is a laboratory certified to perform
the identifications required for macroinvertebrates. Macroinvertebrates were identified to
the lowest level required for standard benthic macro invertebrate monitoring.
Benthic Macro invertebrate Analysis
Results of benthic macro irive rtebrate analysis include North Carolina or Hilsenhoff
Tolerance Values, Functional Feeding Groups, Ephemeroptera-Plecoptera-Trichoptera
Index, Species Richness, and Species Diversity.
The North Carolina or Hilsenhoff Tolerance Values assign a value that range from 0 for
organisms very intolerant of organic wastes to 10 for organisms very tolerant of organic
wastes. Functional Feeding Groups establish the level at which organisms gather
nutrients from the aquatic environment. Ephemeroptera-Plecoptera-Trichoptera Index
assigns the following ratings to samples: Excellent 5, Good 4, Good-Fair 3, Fair 2, and
Poor 1 based on the representation of these taxa within the sample. Species richness
numbers reveal the total number of organisms represented in a given sample. Diversity
analysis numbers reveal the total number of taxa represented in a given sample. A given
sample may show a very high number of individuals (richness) present. However, the
number of different taxa represented (diversity) is a better barometer of stream health.
Diversity speaks more about the quality or health of the stream as opposed to the number
of individuals a stream may support, which is represented by the richness number.
ENVIRONMENTAL SERVICES, INC.
Ms. Burbank
21 December 2001
Page 3 of 3
Diversity analysis for reference reaches showed a range between 12 and 15 individual
taxa represented. However, diversity analysis for impacted reaches indicate a range with
a slightly lower number of taxa present in Sample #2 (6 individual taxa), and the number
of individual taxa in sample #3 (12 individuals) falling within the range set forth by the
reference reach.
Richness analysis reveal a range from 22 to 29 individuals represented in the reference
reaches. However the range for species richness within the impacted reaches indicates a
range between 37 and 39 individuals.
Summary
ESI has conducted four Individual Qual 4 benthic macroinvertebrate collections as
outlined by the North Carolina Division of Water Quality, on Leak Fork Creek. Richness"
within the impacted reaches was found to be higher than that of the reference reaches.
Lower diversity may at times be a cause for increases in richness through a change in
aquatic resource structure, however, diversity of taxa represented in both the reference
and impacted reaches have similar ranges, with some overlap in total diversity. The EPT
Index, a better measure of community structure, shows that the impacted reach is
comparable to the reference reach. The impacted reaches do contain a fauna that is more
tolerant of water conditions, as evidenced by the Biotic Index. Overall, the impacted
reach benthic macro invertebrate faunal community appears to be slightly less diverse
than the reference reaches, but similar in EPT Index. Additional monitoring will
determine whether the impacted reach will trend towards reference condition.
Environmental Services, Inc., appreciates this chance to offer our services to Mitchell &
Associates, Inc. Environmental Consultants, on this project and we look forward to
working with you again in the future. If you have any questions, please feel free to
contact me or Eric L. Renninger at [phone].

I've looked over the benthic macroinvertebrate monitoring plan for this project. Site selection
appears to be appropriate. However, it is noted in the monitoring plan that samples were
collected in November prior to construction. Therefore I would recommend that all post
construction samples be collected during November surveys as well to avoid any seasonal w
variation in the data. Also I would recommend that Qual-4 samples be used for collection in the J?t'LL
UT to Leak Fork Creek, but that full scale surveys be conducted in Leak Fork Creek (see ?f
specifications in the Technical Guidance manual). I'm assuming that Leak Fork Creek at Larry's t
Homes has a catchment size of greater than one square mile.

buffers, but does require that the restored Leak Fork Creek be planted in woody
vegetation (preferably trees) no less than 15 feet from the bank full edge. The
Proposed Mitigation Plan (Mitchell & Associates, May 29, 2001) states that the
created stream shall be located in a 30 foot buffer zone. In accordance with the
settlement agreement and the Proposed Mitigation Plan, restored Leak Fork Creek
shall be located in a riparian buffer that measures 15 feet from the bank full edge
(both sides), and the created stream (tributary to Leak Fork Creek) shall be
located in a 32 foot riparian buffer measured from the toe of the separation berm
to the outer edge of the created floodway.

(2) PEBBLE COUNT DATA and SEDIMENT TRANSPORT ANALYSIS
A sediment transport analysis can confirm that a stream has been properly
designed. It is necessary that the predicted sediment transport in the design
stream be demonstrated to be in equilibrium to ensure overall stability will be
achieved. Please submit your sediment transport analysis and pebble count
information.
Please see the attached Proposed Mitigation Plan (Mitchell & Associates, Revised
12/01) for the required Pebble Count Data and Sediment Transport Analysis.
(3) MORPHOLOGIC MEASUREMENTS TABLE
Please complete and submit the Morphological Measurements Table, provided
in Appendix B of the Internal Technical Guide for Stream Work in North
Carolina, April 2001.
Please see the attached Proposed Mitigation Plan (Mitchell & Associates, Revised
12/01) for the required Morphological Measurements Table.
PHYSICAL MONITORING
Please refer to the NC Wetlands Restoration Program's Draft Physical and
Vegetation Monitoring Outline (Success Criteria), available at
http.-11h2o.ehnr.state.nc.uslncwetlandslrestore.html. Please specify how you
intend to monitor dimension, pattern, and profile of the restored channels.
Your site plans/map should depict locations of permanent cross-sections, photo
reference points, etc. Also note that you will be required to submit annual
Monitoring Reports to the Division for five (5) years within 30 days of the
anniversary of the completion of the stream restoration, per the August 17`",
2001 Settlement Agreement, Item 3.D.e.
The attached site plan shows the location of riparian buffer zones and permanent
monitoring locations. Please see the Proposed Mitigation Plan (Mitchell &
Associates, Revised 12/01) for additional details of the Physical Monitoring Plan.
(5) BENTHIC MACROINVERTIBRATE MONITORING
Your proposal notes sampling in October and February of each year. This is
not necessary. It is recommended that you select one season, the summer
months are preferred, and be consistent between years.
To document the effects of culvert removal, The Division feels that it may be
possible for the first sample to be collected from inside the culvert along Leak
Fork Creep We are also concerned for your health and safety; however, and
recommend that you check with all appropriate agencies (OSHA, for example)
and organizations (Unions) to ensure the safety of the samplers.
Please note that the organization(s) which will be collecting and identifying the
samples must be certified. Please see Appendices 3 and 4 of the Interim,
Internal Technical Guide: Benthic Macroinvertibrate Monitoring Protocols for
Compensatory Stream Restoration Project, May, 2000, which is available at the
above mentioned website, for more information.

A firm certified in the collected of the above described data has been retained to
perform these services. The collection and monitoring report are not yet
complete. Attached in the Mitigation Plan by Mitchell & Associates is copy of
the contract executed to obtain the required data.
LEAK FOR CREEK CULVERT
Per the above referenced settlement agreement, Item 3 G, please provide plans
and specifications for forcing Leak Fork Creek base flow into one culvert, i.e.
partially "plugging" one of the two culverts. Keep in mind that if your plans
include the use of poured concrete structures, the Division has concerns
regarding the use of live concrete in and adjacent to surface waters and special
consideration must be given to how the structure will be established without
allowing live concrete to enter the stream.
The plans for removing sections of Leak Fork Creek and partially "plugging"
Leak Fork Creek do call for poured in place concrete structures. Live concrete
will be prevented from entering Leak Fork Creek by diverting flow of the live
stream around any poured concrete until the new structures sets. Please see the
attached design narrative for more details regarding the protection of Leak Fork
Creek against introduction of live concrete.
(7) EROSIONAND SEDIMENTATION CONTROL PLAN
Keep in mind that the appropriate Designated Non point Source Agency (the
City of Winston-Salem Inspections Division, in this case) must review and
approve your Erosion and Sedimentation Control Plan, which is to be revised
accordingly.
A revise Sedimentation and Erosion Control Plan was submitted to the City of
Winston-Salem on October 12, 2001. We have received verbal confirmation from
local staff that the plan is acceptable, as submitted on that date, and that final
approval cannot be given without notification from DWQ that the plan is
approved in regard to stormwater treatment and stream restoration. Upon receipt
of that approval, we will revise the S&E plan (if necessary) and resubmit to the
City of Winston-Salem for final plan approval prior to commencement of
construction activities.
(8) STORMWA TER MANAGEMENT PLAN
Please submit your plans and specifications for stormwater management
facilities designed to remove 85% TSS according to the most recent version of
the NCDENR Stormwater Best Management Practices Manual. Please also see
the August 17`h, 2001 Settlement Agreement, Item 3.B. for additional
information regarding the design of an extended detention wetland(s). If the
runoff from the project site cannot be added to the wetlands, bioretention areas,
consistent with the Manual designs, must be provided to treat the runoff from
the areas not draining to the wetlands. You can contact Mr. Todd St. John at
919-733-9584 if you have any questions regarding this issue.
The above referenced settlement agreement specifies that an extended detention
wetland facility "may" be provided. It does not specify that an extended detention
wetland facility shall be provided. The verbiage of the settlement agreement
vegetated filter. All runoff from the project will be diverted to the wet detention
basin, so no additional bioretention areas are necessary.
gives us the option, not requirement, of using wetlands as stormwater treatment.
We choose to use a wet detention basin to satisfy the stormwater treatment
criteria. The attached calculations in the Design Narrative demonstrate the
proposed wet detention basin will remove 90% TSS without the use of a
I trust this information to be sufficient for your review and approval. If you have any
questions, comments, or require additional information regarding this matter, please

DESIGN NARRATIVE
1. GENERAL:
The project site is located off Patterson Avenue in the city of Winston-Salem, North Carolina,
Forsyth County. The project area is approximately 9.05 acres. Erosion Control considerations
are to be in accordance with the City of Winston-Salem requirements.
The intent of this project is to comply with a settlement agreement stemming from an
enforcement action with the North Carolina Department of Environment and Natural Resources,
Division of Water Quality. Reference file number 01 HER 1378.
2. EXISTING SITE:
An existing gravel parking area fills approximately 4.3 acres of the 9 acre site. The remaining
undeveloped portion of the site is hilly with slopes ranging from five to fifty percent. The site
drains from the south to the north towards Patterson Avenue.
Nearly 900 linear feet of Leak Fork Creek runs through the site, approximately 630 linear feet of
which has been piped. Un unnamed tributary to Leak Fork Creek also runs through the site
(approximately 400 linear feet). Nearly 240 linear feet of the tributary has been piped.
3. PROPOSED IMPROVEMENTS:
In accordance with the settlement agreement between the state of North Carolina and PTR, Inc.,
the total impact to Leak Fork Creek shall be reduce to less than 500 feet. Approximately 130
linear feet of piping installed in Leak Fork Creek shall be removed, leaving the total culverted
length of Leak Fork Creek at less than 500 linear feet Z3f?Te piping to remain, one of the two
culverts shall be partially plugged to force base flow in the stream to pass through a single
culvert. Higher flows produced by storm events will pass through both pipes.
Poured in place concrete structures shall be utilized to secure the pipes to remain (entrance
footers) and to plug one of the culverts (entrance weir). See sheet C-3 of the attached plan set for
construction detail. To protect Leak Fork Creek from introduction of live concrete, the entrance
footers/weir shall be formed and poured one at a time. While concrete work is being installed in
one pipe, a diversion dike shall be constructed to divert all flow to the open culvert pipe. All
poured concrete shall be allowed to set for a in of 24 hours to allow it to harden. The 24
hour cure time is sufficient to protect Leak Fork Creek from introduction of any live concrete.
After 24 hours, the diversion dike shall be rerouted to the open culvert and the entrance footer
constructed at the other pipe. To maintain positive discharge throughout construction, the
entrance footer of the pipe to remain open (no entrance weir) shall be constructed first. The
entrance footer that includes a weir to plug the invert shall be constructed second.
To mitigate the remaining impacts to Leak Fork Creek and its unnamed tributary, approximately
1150 linear feet of new stream shall be created where the existing tributary is piped. The created
stream shall be constructed in accordance with the Mitigation Plan prepared by Mitchell &
Associates (revised 12/7/01). Please see the attached plan set for proposed grading and
construction details for the stream creation.
Finally, all runoff from impervious surfaces shall be collected and treated to remove 90% TSS.
A wet detention basin, designed in accordance with Division of Water Quality Best Management
Practices, is proposed for the site. The proposed wet detention basin receives runoff from the
entire project, so no alternative treatment measures are necessary. Please see the attached plan
set for proposed grading and construction details of the proposed wet detention basin. Attached
calculations demonstrate the treatment capacity of the proposed basin in accordance with
Division of Water Quality Best Management Practices.
4. EROSION CONTROL CONSIDERATIONS:
All erosion control measures to comply with the City of Winston-Salem requirements. This
project will utilize silt fencing, diversion berms, a stormwater pond and a rock dam to control
and treat sediment runoff.
-__ --err" th-li ly-eroC ibte sons in this area, special consi?erations were given to the velocities of - -------
concentrated flows as shown in the attached calculations. In compliance with the approved
mitigation plan, a riff (or plunge pool) will be used to dissipate velocities coming off the steep
hillside.
5. MAINTENANCE CONSIDERATIONS:
During construction, the Contractor shall be required to inspect and repair as needed all erosion
control devices after any significant rain event. Any measure found not performing its intended
function shall be repaired immediately. Upon completion of construction and establishment of
permanent ground cover, the Owner shall be responsible for maintenance on the project site.

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 a e bu ers o pro ec open waters??re?ms;-a?rd-reglacizrg-iosses-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.ne.us/newetlands/strmgide.httnl.
1. 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.
This nroiect has two phases of compensatory mitigation. The first is to remove 650
linear feet of culvert located in Leak Fork Creek to lessen the culverts length to 500 feet
or less The second phase is to create 1250 feet of stream that begins where the
unnamed tributary meets the western property boundary. This stream will meander
north and east until reaching Leak Fork Creek. Attached a copy of the latest draft
mitigation plan which has been given DWQ and ACOE approval.

1.01 INTRODUCTION
Mitchell & Associates, Inc., on behalf of Rocky Carter, has undertaken the project of creating a
mitigation plan for all stream impacts that have occurred on the property located northwest of
Winston Salem, Forsyth County, North Carolina (Appendix 1, map la. and lb.). The mitigation
plan includes minimizing impacts to Leak Fork Creek to less than 500 linear feet, and relocating
the impacted unnamed tributary to the back of the property. Rosgen steam restoration techniques
are to be used, as outlined in the following plan (Rosgen 1996). Restoration of the impacted
streams will be described in this report and will adhere to the regulations of the U.S. Army Corps
of Engineers (USACOE). This mitigation plan, when implemented, will effectively enhance and
restore existing streams on the project site as well as improve the existing downstream water
quality of Leak Fork Creek.
1.1 Site Description
The property is located on the west side of Patterson Avenue and approximately 1400 feet north
of the intersection of Motor Road in Forsyth County, Winston Salem, North Carolina (Map2).
The site is bounded by route 52 and a Duke Power Right of Way (ROW) located on the west
side. Leak Fork Creek is a shallow tributary that lies within the valley parallel to Patterson
Avenue on the property's west side . The creek has an average bank to bank stream width of 20
feet, has a north directional flow, and shows channelization further downstream.. Evidence of
rapid erosion can be seen in several places along the creek banks, and silt fences were placed in a
few areas to help reduce the erosion presently taking place. Green algae (family Chlorophyta)
was found growing throughout the bottom of the creek. The surrounding area primarily consists
of patches of woody vegetation, numerous grasses, and small to medium rocks. Trash material
was observed along the creek banks as well as within the water. A sewer line runs parallel to
Leak Fork Creek and there is evidence that creek now was altered due to the placement of the
sewer line. The actual site itself has been graded, filled, and is covered with gravel up to its
boundaries .
1.2 Soil Series Description
The soils located on the property are from the Wehadkee Series and Pacelot Series ( Appendix
2). The Pacelot Series consists of Pacelot fine sandy loam and clay loam and can typically be
found on slopes from 10 to 45 percent. These soils are well drained with moderately slow
infiltration and rapid runoff. The Wehadkee Series, in particular Wehadkee loam, is classified as
a hydric soil and characterized as being poorly drained and is located on the flood plain of
streams. Infiltration is moderate and surface runoff is slow. These soils are also subject to
frequent flooding for brief periods of time and can be found on 0 to 2 percent slopes (SCS 1976).
1.3 Vegetative description
Due to the entire site being covered with gravel vegetative data was gathered from immediately
north and south or the property. The overstory consisted of Fraxinus pennsylvanica (green ash),
Populus deltoides (eastern cottonwood), Acer rubrum (red maple), Quercus nigra (water oak),
Quecus phellos (willow oak), Quercus alba (white oak), Pinus taeda (loblooly pine),
Liquadambar styraciflua (sweetgum), Platanus occidentalis ( sycamore), and Liriodendron
tulipifera (yellow poplar). The understory vegetation consisted of native grasses, Eupatorium
cappillifolium (dog fennel), Rosa sp. (Wild rose), andPhytolacca americana (pokeweed).
2.0 PROPOSED MITIGATION PLAN
The following proposed mitigation option was introduced by the U.S. Army Corps of Engineers
to re-establish stream areas on-site and to resolve enforcement matters. This mitigation plan
involves removing a portion of the culvert located in Leak Fork Creek and restoring the area to
natural conditions. In addition, our client will be required to relocate the impacted unnamed
tributary to the back of the property using approved Rosgen techniques. Rosgen techniques
involve analyzing stream characteristics including geomorphic, chemical, biological processes
and there functions. Once this data is collected, the new tributary will be created for optimum
function.
2.1 Mitigation Procedure
Mitchell & Associates, Inc., has developed the following mitigation plan to resolve the
previously mentioned enforcement matters. Our client will be required to minimize the present
630 linear feet of impacts to Leak Fork Creek to less than 500 linear feet. This will require
approximately 130 linear feet of the creek to be opened, a new natural path of flow established,
the creek bank re-established, and the placement of vegetation and root wads along the stream
banks for stabilization and erosion control. The second component of the mitigation plan is
related to the impacts associated with the filling of the unnamed tributary previously located on
site. This phase begins with redirecting the new tributary, presently ceasing at the rear of the
property, east of HWY. 52 along the perimeter of the project site. This redirection will create
approximately 1150 feet of meandering stream which will connect with Leak Fork Creek.
Redirecting the stream will provide the streamflow with a cleaner bed, as opposed to the original
which was littered with trash. Detailed below is the methodology and data associated with
implementing this mitigation plan.
2
2.11. Culvert Removal and Stream Restoration
The culvert located in Leak fork Creek is presently approximately 630 linear feet in length and
begins on the Northern property boundary and ends on the southern property boundary (pictures
12 and 13). This culvert consists of two large 11' pipes that have provided adequate space for
high stream flow. A portion of the culvert (130 ft.) at the southern property boundary end is to
be removed, and subsequently this area of stream will be restored to its previous natural
conditions.
Leak Fork Creek can be characterized as a G5 type stream that is undergoing degradation and
widening. This is characterized by the high width to depth ratio and the presence of undercutting
and sloughing of the banks both upstream and downstream of the culverts. The banks are
primarily being stabilized by grass vegetation, litter consisting of metal, cinder blocks and other
debris, shrubs and root material from overstory trees. The erosion is significant where meanders
are present, with undercutting on the outer portion and sloughing on the inner portion. The width
of the channel ranges between 8 and 12 feet while the bankful width is approximately 18-26 feet.
Water depth ranges from 2 inches to 16 inches, varying according to the presents of pools and
rifles.
Reference Reach data was collected immediately upstream from the project site to gather data for
restoring the project site. Stream characteristics immediately upstream where the most desirable
to use for a reference reach because characteristics were almost identical. We felt they were
sufficient for this phase of the project since our goal was not to restore a complete stream reach.
A permanent bench mark was established, as noted on Sheet C-2 (Cape Fear Engineering).
Attached (Appendix 3a) is our worksheet of morphological characteristics for the reference
reach, longitudinal and cross-sectional photographs, pebble count data, hydrological analysis, and
site maps which include stream morphology.
The previously culverted section of the stream will be restored to a natural state with measures
being undertaken to prevent subsequent erosion. Heavy equipment will be used to remove fill
material and the two pipes in the culvert, during which erosion control measures will be
undertaken to avoid contamination to the creek. This will be in the form of silt fences placed
around the construction areas. If necessary the flow of leak Fork Creek will be pumped around
the work area to avoid contamination of the waters.
The creek bank will be sloped at a 2:1 angle. This will mimic healthy stream characteristics and
prevent further erosion to downstream areas. The 2:1 slope offers optimal stability with less
need for increased stabilization methods. (MRCS 1998). Bank tops will be given a rounded edge
to form a gradual transition between upland and slope to allow for suitable plant growth.
Excelsior mat will be used to cover bank slopes for stability and native riparian vegetation will
be planted at two foot intervals. This vegetation live staked or planted on the banks will consist
of Alix nigra, Agnus serrulate, Calycanthus floridus, Ilex verticillata, Celtis laevigata,
Xanthorhiza simplicissima, Rhododendron viscosum, Quercus phellos. In addition to the above
3
vegetation on bank tops and within the buffer zone Euonymous americanus, Itea virginica,
Rhododendron arborescens, Betula nigra, Caprinus caroliniana, Crataegus marshalii, and
Quercus nigra will also be planted. Creek bed material is available on site and will be consistent
with the present bed material which ranges from silt/clay to boulders. The Cape Fear
Engineering design plans contain work plans and maps of what is to be accomplished.
2.12 Stream Creation
An unnamed tributary once entered the property from the west from a culvert that extends under
Hwy. 52. This tributary presently descends approximately 200 feet through a gully from HWY.
52 and ends at the property line. This stream can be classified as a type B stream, is narrow ( 1-2
feet wide), and shallow with a depth of 1 foot. The banks of this tributary are low and at an
approximate 1:5 slope. The southern bank of the tributary has an associated flood plain area
where the northerly side of the stream buts up against a steep gradient with a 1:1.5 slope. It is
bordered by grassy riparian vegetation and shrubs in addition to oaks and maples. Bed material
consists of silt/clay through cobbles.
Due to the short lenth of this unnamed tributary, our reference reach is the 201 feet of stream
presently in existence. A permanent benchmark has been established and all data has been
gathered from this area. Attatched (Appendix 4a), is our reference reach data for the unnamed
tributary and corresponding photographs.
Our goal is to create a new path for this tributary that will take an approximately ninety degree
turn north at the property line and meander (1150ft) north-east until falling out in a natural area
before reaching Leak Fork Creek. Because much of the flow volume is associated with rain fall
runoff that comes from HWY 52, the natural area will benefit pollution removal before waters
reach Leak Fork Creek. The tributary will have an average depth of .6 feet and a width of 2-4
feet with low 2:1 sloped banks. The tributary will be located in a 30 foot buffer zone to prevent
contamination and upland runoff from entering.
The first step in creating the new tributary is creating a new path of flow. Heavy equipment will
be used to dig the new stream path. Standard erosion control measures will be undertaken while
work is in progress and vegetative cover is in place. In order to create 1150 feet of stream, the
channel will have a high sinousity as it travels north along the eastern property boundary. As the
channel reaches the north eastern corner the tributary will take a westerly turn where the
elevation changes rapidly. Here we have created a riff to adjust to the rapid 7 foot loss of
elevation. At this point the tributary will have a wide bankful width and an associate flood plain
area for periods of heavy rains. This will facilitate pollutant removal from the waters before they
reach Leak fork Creek.
Banks are to be graded and rounded off, and the soil slightly compacted for planting. Where the
90 degree turn takes place boulders should be placed at the toe of the slope for times of heavy
4
water flow. Immediately after the turn a log vane will be placed on the outside bend to keep
water flow to the center of the tributary. Please see appendix 4a for a more detailed drawing of
morphological data. Live cuttings of willow branches will be staked at 2 foot intervals for
further stabilization. Additional riparian planting will take place in the fall for slope
stabilization. These plantings will consist of willow oak, green ash, water oak, cottonwood, and
black alder. Both the outside bend and the inside will be seeded for erosion control and to
prevent sloughing.
Existing vegetation should be retained to the extent feasible, as should woody debris and stumps.
In addition to providing habitat and erosion and sediment control, these features provide seed
sources and harbor a variety of microorganisms. The same vegetation types will be live staked or
planted within the buffer zone as is being planted along Leak Fork creek, using the same
guidelines and techniques.
At section 4 the stream will take a northerly turn and fall off into a natural area until reaching
Leak Fork Creek. A berm adjacent to the property line will be constructed to keep water flow
contained on the property. Stabilization of the stream in the bend will imitate the methods used
in the section 1, 90 degree turn. The naturalized area should not require any additional seeding
or planting since adequate vegetation is already present.
2.13 Time Frame and Monitoring
Time Frame of project
Below is an outline of the time frame necessary to complete the restoration and stream creation
project. It is our goal to have the 130 foot portion of pipe removed from Leak Fork Creek, bank
slopes laid back properly, and the new channel for the unnamed tributary dug, laid back, and
prepared for planting with in a 45 day time period.
The optimum conditions for successful plant installation are when temperature, moisture, and
sunlight are adequate for germination and establishment. In the eastern United States these
conditions are met beginning in mid winter to early spring. In addition plants should be installed
when dormant for the highest rate of survival. To meet these conditions planting should begin in
November to February depending on weather conditions. These plants will be acquired from a
local commercial source. It is our best estimate that approximately 6,500 plants including willow
oak, green ash, water oak, cottonwood, and black alder will be needed to adequately cover the
lower banks of both the restored section of Leak Fork Creek and the new unnamed tributary.
That number is derived from channel length and bank width with a planting every 2 square feet.
This total achieves 500 trees per sq. acre.
Monitoring and Success Criteria
Mitchell & Associates will implement a site inspection and monitoring plan to ensure the success
of the project. This plan will meet standard procedures for monitoring a project, and include
assurance that the site meets with success criteria for restoration projects.
Within 60 days of completion of mitigation site construction, Mitchell & Associates will submit
a report indicating all work completed and will include: photographs of completed work, the
stream reference reach, longitudinal profiles and cross sections of reference reaches, vegetation
sample plots with locations, and problems encountered and resolved. The location of cross-
sections of reference reaches and vegetative plots are noted on the enclosed map.
Follow up inspections will be conducted on a regular basis and documented in the form of data
summaries and field notes. Sketches, maps, and photographs will be used to document
vegetation development, channel stability, and structure performance.
Vegetation within the buffer zone will be inspected for a period of five years or until success
criteria is met, which ever is the longer period of time. Vegetation will be inspected in August or
September of each year after planting, and at a minimum, no one species should exceed 20
percent of the total number of individuals. Success criteria will be met if, for each of the first
three years after monitoring, a minimum of 320 trees per acre of the planted species have
survived. In years four and five, a minimum of 288 to 260 four year old trees per acre have
survived on the site, and after year five a minimum of 260 five year old trees have survived. If
this vegetation criteria is not met, replanting will take place and the five year monitoring period
will begin again. Vegetation will also be inspected for the presence of exotic, harmful species
that if detected will be removed. Vegetative plots where data is collected will be taken at the 6
areas noted and labeled on the map.
Stream banks will be inspected 2 times annually during the first two years after project
completion, and one time annually there after for a period of five years. The entire stream
corridor will be inspected to detect areas of erosion or accumulation. Inspection of bank and
channel conditions will be conducted during low water conditions to allow for viewing of
complete structures and channel bed changes. Photo reference sites (longitudinal photos and
lateral reference photos) will be used and monitoring of the reach's cross-section and
longitudinal profiles. Success criteria will be met if, for the period of five years in conjunction
with the vegetation monitoring, the stream bed features and cross-sections remain stable. The
stream shall retain its enhanced Rosgen's steam type classification. If any problems are
encountered, the stream channel will immediately be restabilized and planted.
Benthic Macroinvertebrate Monitoring
Mitchell & Associates Inc., does not have certified personnell on staff to perform sampling
6
procedures, hence Environmetal Sevices Inc., has been contrE ing. Data
collected will be reviewd by Mitchell & Associates and then sent to govviLiLxxxr, -,,-..cies as
required. We will also include these results in our annual monitoring reports. Benthic?
macroinvertebrate monitoring will be conducted prior to stream disturbance, and will be
followed up with three years of biological monitoring starting one year after project completion. ;
Summer is the preferred time for monitoring, hence we will sample in July post project and ?(p a
period of three years thereafter. Our first samples, however,were collected on November 20,
2001 just prior to the start of the project. This was necessary due to time constraints and 0
deadlines associated with the project. P4??• Lk
The monitoring will be conducted at four locations. The first location will be at Leak Fork creek, '?
on the project site where the culvert is to be removed.. The second sample site will be taken
immediately upstream of the property where the unnamed tributary meets the property boundary.,,
At this pre-project time the unnamed tributary ceases at the project boundary. Post stream
creation the third monitoring site will be located within the center of the newly created unnamed
tributary. A fourth monitoring site will be located 500 feet upstream of Leak Fork Creek from
the property line, which is in our reference reach.
The Qual-4 collection technique will be employed for sampling for benthic macroinvertebrates.
This method is accepted for 1 st and 2nd order streams. Four sample types will be collected at'
each monitoring area including one kicknet sample, one sweep net sample, one leafpack, and
"visuals". All organisms will be collected and processed.
/-t-7
Written reports containing all relevant information including stream appearance, water quality a?
data, and sample results, facts, and figures will be submitted to the DWQ within 30 days after the
field monitoring takes place. Every effort will be undertaken to meet DWQ standards.
The above proposed mitigation plan meets USACOE standards and will in fact improve the
quality of Leak Fork Creek and its associated unnamed tributary.

Dear Mr. Fennell: Z;
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that additional
information is necessary to complete the technical review process. The required additional information is as follows:
1. Operation and Maintenance Agreement
An operation and maintenance agreement is required. The agreement must include some means of drawing down
the entire permanent pool for maintenance, such as a pump. The operation and maintenance agreement must also
be signed by the responsible party and notarized. An example agreement for an extended detention wet pond is
available on line at hnl),/fh2o.enr.state.nc.us/ncwetlandsloandm.doc.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. If you have any questions or would like to discuss this project, please contact me at (919) 733-
9584. Also, please note that the NCDENR Stotmwater Best Management Practices Manual, April 1999, and other
documents and information Gan be downloaded from the Wetlands Unit web site at
http;/Rt2o.ehnr.state.nc.usln4wetlandsl. Please note that any issues regarding the stream mitigaticn plan will be
addressed in separate correspondence.

Dear Mr. Fennell:
The Wetlands Unit staff reviewed the stormwater management plans for the subject project and determined that add
information is necessary to complete the technical review process. The required additional information is as follows:
1. Operation and Maintenance Agreement
An operation and maintenance agreement is required. The agreement must include some means of drawing own
the entire permanent pool for maintenance, such as a pump. The operation and maintenance agreement mu !V also
be signed by the responsible party and notarized. An example agreement for an extended detention wet pond is
available on line at http://h2o.enr.state.nc.uslncwetiands/oandm.doc.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of receipt of the
requested information. If you have any quesfions or would like to discuss this project, please contact me at (919) 733-
9584. Also, please note that the NCDENR Stormwater Best Management Practices Manual, April 1999, and other
documents and information can be downloaded from the Wetlands Unit web site at
http://h2o.ehnr.state.nc.us/ncwetiands/. Please note that any issues regarding the stream mitigation plan will be
addressed in separate correspondence.

Thanks, all. I will get a response off to opposing counsel.
>>> John Dorney <[e-mail]> 07109101 09:02AM >>>
Anita - here are DWQ comments on the proposed PTR settlement. Basically it is
a fair (not good) start but needs lots of work and expansion. Part of the
problem is that the consultant had not consulted (isn't that what they are
supposed to do?) with us on his report but apparently he did consult with the
Corps of Engineers. The conditions below are what we would normally require
from anyone who followed the rules and applied before the impact. We feel vary
strongly that we need to hold to these provisions. Otherwise the developer
will be "rewarded" for not applying while his counterparts are "penalized" for
following the rules.
1. Reduce the culverting of Leak Fork Creek. The proposed retention of
500 feet of pipe is unjustified as far as we can see. Crossing of the creek
for one (or possibly two if justified) road crossings is fine but more than
that is avoidable.
2. On-site stormwater management is needed for the new stormwater from
this commercial site. A wet detention pond would be acceptable.
3. Relocation of the smaller tributary. We have lots of questions here
probably because we do not have a copy of the map that is referenced in the
report. Our basic questions are 1) are there plans for the relocation?, b)
will the design be bassed on a reference stream?, c) are wooded buffers to be
on both sides of the creek?, d) are buffers to be wooded and what is the
width?, e) biological monitoring will be required for the stream relocation,
and f) DWQ must review and approve the overall mitigation and monitoring plan.
4. Of the two pipes installed in Leak Fork Creek, one must be either
raised or partially plugged so that low flow only goes through one pipe so the
low flow is not spread out too much and the aquatic habitat then removed.
5. Delete sweet gun and sycamore from the proposed plantings.
6. What is the proposed buffer width on the restored portion of Leak Fork
Creek? Is it to be planted with trees or shrubs?
7. The maps referenced in the report were not included.
Please call me at 733-9646 if you have any questions. Thankx

JD, I agree with you observations about the monitoring plan provided by
Mitchell and Associates. It needs lots of work. I would stress to them
that they need to comply with DWQ guidelines when presenting monitoring
plans. I think my biggest beef is with the design and monitoring of the
new tributary. Reference conditions are not noted, ya da, ya da, ya da.

I offer the following to John for his consideration as he "generates" a
response:
1. Close coordination of any settlement resolution with the Corps is
essential.
2. Removal of pipes down to roughly 400 (or less) linear feet on Leak Fork
Creek should be pursued instead of targeting the removal of only 160 linear
feet. This does not get them below the 500' proposed by the consultant as
they impacted around 850 feet of the main stream, if I remember correctly.
3. Who gets the money from the settlement? Instead of a large fine or
settlement amount ($6,592.28) payable to the school system, funds should be
paid (as part of mitigation) to a program such as WRP, CWMTF or the
Piedmont Land Conservancy. Then, they can use the funds for stream and
habitat preservation/restoration purposes in the county or subbasin area.
4. Whatever amount of double piping remains in Leak Fork Creek, ONLY one
barrel should receive base flow. The other barrel should be silled with
adequate floodplain benching, etc. to ensure a single base channel flow ,
with enough depth for passage. The pipe should not be allowed to have
damming or freefalling waters on either end of the base flow channel unless:
bioengineering efforts provide for adequate warm water fish passage.
5. Stormwater management and mitigation may need further consideration as
this is a commercial site in a floodplain and the two streams probably had
different types of.aquatic communities, albeit both appear to be ..perennial.
The main (USGS blue line) stem of Leak Fork Creek will lose both fish and
riparian vegetation habitat. The smaller tributary was probably more
bottomland hardwood.
Note: I am not sure if you will have enough water to maintain the smaller
stream for a longer distance. It will be essential to know how much water
this stream can provide before deciding to lengthen it considerably. It
should be designed according to accepted bioengineering techniques for the
flow and slope.
Later,
Ron

PTR Settlement Comments:
The Corps of Engineers Public Notice indicated 850 feet of culvert impacts
to Leak Fork Creek and 660 feet to an unnamed tributary of Leak Fork
Creek. Conversely, the settlement offer only proposes to remove
approximately 160 feet of culvert from Leak Fork Creek and to restore the unnamed tributary to a new
1250' channel.
The settlement agreement should clearly stipulate how much mitigation
will take place on site and off site for each respective stream segment
impacted. That is, the restoration of the 660-foot of the culverted
unnamed tributary to Leak Fork Creek into a new stream channel totaling 1250 feet of stream is
proposed. It is staff's understanding that this alternative was chosen
in lieu of 1:1 off site mitigation for the impacts to this
unnamed tributary.
The remaining impacts, detailed in a Public Notice by the Corps
indicates that 850 feet of culverted impacts occurred on the Leak Fork
stream segment. Accordingly, only 160 feet of the stream will be
restored by the removal of culverts. Therefore, 690 feet of restoration

Re: PTR
or mitigation for Leak Fork Creek has not been addressed. Compensatory mitigation for the remaining
690 feet is required at a 1:1 ratio. The restoration of the unnamed tributary is acceptable mitigation for
the unnamed tributary impacts only - not for Leak Fork Creek impacts, as the two stream are not
comparable. Further, it was staff's understanding that the majority of the culvert on Leak Fork Creek
would also be removed and only a minimum length needed for a single road crossing would remain.
Settlement offer states that they will implement the "Monitoring and Mitigation Plan" to the
satisfaction of the Corps. The Monitoring and Mitigation Plan must also meet with Division
approval. A detailed stream restoration plan and monitoring proposal must be submitted to the
Division for review and approval.
A Stormwater management plan and implementation schedule should be
required in the settlement offer. This plan and schedule must also be submitted to and approved by the
Division. (Note: the settlement proposal did not address stromwater management.)
The settlement offer should require PTR to appropriately modify their
erosion and sediment control plan.

DWQ Project # 01 1381
Forsyth County
Dear Applicant:
The Division of Water Quality has reviewed your plans for the culvert removal and
restoration of approximately 350 linear feet of Leak Fork Creek and approximately 1250 linear feet
of an unnamed tributary to Leak Fork Creek, Class C waters, Yadkin-Pee Dee River Basin, Forsyth
County for the purpose of resolving Water Quality Violations and subsequent Enforcement Action.
Insufficient evidence is present in our files to conclude that your project must be built as planned in
waters and/or wetlands in accordance with 15A NCAC 2H.0506 and will place this project on hold
as incomplete until we receive this additional information. We are requesting (by copy of this letter)
that the U. S. Army Corps of Engineers place your project on administrative hold.
(1) SITE PLANS/MAPS
Please submit a detailed site plan/map that must contain the information specified in
Section 2.3.3 of the Internal Technical Guide for Stream Work in North Carolina,
April 2001, Locate the stream features (such as riffles, pools, run and glides) and
appropriate riparian buffers (see PTR, Inc. v. NCDENR-DWQ Settlement
Agreement, signed August 17, 2001) on the site plan.

Customer Service
1 800 858-0368
(2) PEBBLE COUNT DATA and SEDIMENT TRANSPORT ANALYSIS
A sediment transport analysis can confirm that a stream has been properly designed.
It is necessary that the predicted sediment transport in the design stream be
demonstrated to.be in equilibrium to ensure overall stability will be achieved. Please
submit your sediment transport analysis and pebble count information.

(3) MORPHOLOGICAL MEASUREMENTS TABLE
Please complete and submit the Morphological Measurements Table, provided in
Appendix B of the Internal Technical Guide for Stream Work in North Carolina,
April 2001.
(4) PHYSICAL MONITORING
Please refer to the NC Wetlands Restoration Program's Draft Physical and
Vegetation Monitoring Outline (Success Criteria), available at
http://h2o.ehnr.state.nc.us/ncwetlands/restore.htm]. Please specify how you intend to
monitor dimension, pattern and profile of the restored channels. Your site plans/map
should depict locations of permanent cross-sections, photo reference points, etc.
Also note that you will be required to submit annual Monitoring Reports to the
Division for five (5) years within 30 days of the anniversary of the completion of the
stream restoration, per the August 17`h, 2001 Settlement Agreement, Item 3.D.e.
(5) BENTHIC MACROINVERTIBRATE MONITORING
Your proposal notes sampling in October and February of each year. This is not
necessary. It is recommended that you select one season, the summer months are
preferred, and be consistent between years.
Please include the benthic macroinvertibrate monitoring locations on your site map.
To document the effects of culvert removal, The Division feels that it may be possible
for the first sample to be collected from inside the culvert along Leak Fork Creek.
We are also concerned for your health and safety; however, and recommend that you
check with all appropriate agencies (OSHA, for example) and organizations (Unions)
to ensure the safety of the samplers.
Please note that the organization(s) which will be collecting and identifying the
samples must be certified. Please see Appendices 3 and 4 of the Interim, Internal
Technical Guide: Benthic Macroinvertebrate Monitoring Protocols for.
Compensatory Stream Restoration Project, May 2000, which is available at the
above-mentioned website, for more information.
Please contact Mr. Dave Penrose, DWQ 40l/Wetland Unit, at 919-733-9502 if you
have any questions regarding this matter.

(6) LEAK FORK CREEK CULVERT
Per the above-referenced Settlement Agreement, Item 3 G, please provide plans and
specifications for forcing Leak Fork Creek base flow into one culvert, i.e. partially
"plugging" one of the two culverts. Keep in mind that if your plans include any
poured concrete structures, the Division has concerns regarding the use of live
concrete in and adjacent to surface waters and special consideration must be given to
how the structure will be established without allowing live concrete to enter the
stream.
(7) EROSION AND SEDIMENTATION CONTROL PLAN
Keep in mind that the appropriate Designated Non-point Source Agency (the City of
Winston-Salem Inspections Division, in this case) must review and approve your
Erosion and Sedimentation Control Plan, which is to be revised accordingly.
(8) STORMWATER MANAGEMENT PLAN
Please submit your plans and specifications for stormwater management facilities
designed to remove 85% TSS according to the most recent version of the NC DENR
Stormwater Best Management Practices Manual. Also please see the August 171H,
2001 Settlement Agreement, Item 3.B. for additional information regarding the
design of an extended detention wetland(s). If the runoff from the project site cannot
be added to the wetlands, bioretention areas, consistent with the Manual designs,
must be provided to treat the runoff from the areas not draining to the wetlands. You
can contact Mr. Todd St. John at 919-733-9584 if you have any questions regarding
this issue.
Please respond, in writing, both to this Office and to John Dorney, 2321 Crabtree Blvd.,
Parkview Building, Raleigh, NC 27604-2260 within three weeks of receipt of this letter,
addressing the items listed above.

Hey Todd,
Thanks - I actually had a brief conversation with Danny on Friday about the standard
this or we'll deny" language... so, in answer to your question, no, we are not moving
towards denial - and that language will be modified. Thanks for pointing it out.
I will also include the wetland requirement in No. 8. thanks.

DESIGN NARRATIVE
L GENERAL:
The project site is located off Patterson Avenue in the city of Winston-Salem, North Carolina,
Forsyth County. The project area is approximately 9.05 acres. Drainage considerations are to be
in accordance with NCDENR stormwater requirements.
The intent of this project is to comply with an enforcement action stemming from a settlement
agreement with the North Carolina Department of Environment and Natural Resources, Division
of Water Quality. Reference file number 01 HER 1378.
2. EXISTING SITE:
An existing gravel parking area fills approximately 4.3 acres of the 9 acre site. The remaining
undeveloped portion of the site is hilly with slopes ranging from five to fifty percent. The site
drains from the south to the north towards Patterson Avenue.
3. PROPOSED STORMWATER IMPROVEMENTS:
Proposed stormwater improvements include the construction of a wet detention basin. Existing
stormwater piping that caries untreated water will be abandoned in place. All of the existing
impervious parking areas will sheetflow to the basin for treatment. The remaining undisturbed
lands will sheetflow to existing creeks and waterways. The design of the wet detention basin is
based on a 95% impervious coverage.
4. DRAINAGE CALCULATION CONSIDERATIONS:
Drainage calculations have been provided for the wet detention pond, spillway and emergency
spillway. A portable pump will be used as an emergency/maintenance drain.
5. EROSION CONTROL CONSIDERATIONS:
All erosion control measures will comply with the City of Winston-Salem requirements.

DWQ Project # 01 1381
-Forsyth County
Dear Applicant:
The Division of Water Quality has reviewed your plans for the -culvert removal and
restoration of approximately 350 linear feet of Leak Fork Creek and approximately 1250 linear feet
of an unnamed tributary to Leak Fork Creek, Class C waters, Yadkin-Pee Dee River Basin, Forsyth
County for the purpose of resolving Water Quality Violations and subsequent Enforcement Action.
Insufficient evidence is present in our files to conclude that your project must be built as planned in
waters and/or wetlands in accordance with 15A NCAC 2H.0506 and will place this project on hold
as incomplete until we receive this additional information. We are requesting (by copy of this letter)
that the U. S. Army Corps of Engineers place your project on administrative hold.
(1) SITE PLANS/MAPS
Please submit a detailed site plan/map that must contain the information specified in
Section 2.3.3 of the Internal Technical Guide for Stream Work in North Carolina,
April 2001. Locate the stream features (such as riffles, pools',-run and glides) and
appropriate riparian buffers (see PTR, Inc. v. NCDENR-DWQ Settlement
Agreement, signed August 17, 2001) on the site plan.
(2) PEBBLE COUNT DATA and SEDIMENT TRANSPORT ANALYSIS
A sediment transport analysis can confirm that a stream has been pro rly designed.
It is necessary that the predicted sediment transport in the design stream be
demonstrated to be in equilibrium to ensure overall stability will be achieved. Please
submit your sediment transport analysis and pebble count information.
01 1381
Page 2
(3) MORPHOLOGICAL MEASUREMENTS TABLE
Please complete and submit the Morphological Measurements Table, provided in
Appendix B of the Internal Technical Guide for Stream Work in North Carolina,
April 2001.
(4) PHYSICAL MONITORING
Please refer to the NC Wetlands Restoration Program's Draft Physical and
Vegetation Monitoring Outline (Success Criteria), available at
http://h2o.ehnr.state.nc.us/ncwetlands/restore.html. Please specify how you intend to
monitor dimension, pattern and profile of the restored channels. Your site plans/map
should depict locations of permanent cross-sections, photo reference points, etc.
Also note that you will be required to submit annual Monitoring Reports to the
Division for five (5) years within 30 days of the anniversary of the completion of the
stream restoration, per the August 17`h, 2001 Settlement Agreement, Item 3.D.e.
(5) BENTHIC MACROINVERTIBRATE MONITORING
Your proposal notes sampling in October and February of each year. This is not
necessary. It is recommended that you select one season, the summer months are
preferred, and be consistent between years.
Please include the benthic macroinvertibrate monitoring locations on your site map
To document the effects of culvert removal, The Division feels that it may be possible
for the first sample to be collected from inside the culvert along Leak Fork Creek.
We are also concerned for your health and safety; however, and recommend that you
check with all appropriate agencies (OSHA, for example) and organizations (Unions)
to ensure the safety of the samplers.
Please note that the organization(s) which will be collecting and identifying the
samples must be certified. Please see Appendices 3 and 4 of the Interim, Internal
Technical Guide: Benthic Macroinvertebrate Monitoring Protocols for
Compensatory Stream Restoration Project, May 2000, which is available at the
above-mentioned website, for more information.
Please contact Mr. Dave Penrose, DWQ 401/Wetland Unit, at 919-733-9502 if you

Page 5 of 10
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
blg://h2o.enr.state.nc.us/ncwetlands/strmgide.html.
1. 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.
_ This proiect has two phases of compensatory mitigation. The first is to remove 650
linear feet of culvert located in Leak Fork Creek to lessen the culverts length to 500 feet
or less The second phase is to create 1250 feet of stream that begins where the
unnamed tributary meets the western property boundary. This stream will meander
north and east until reaching Leak Fork Creek. Attached a copy of the latest draft
mitigation plan which has been given DWQ and ACOE approval.
Page 6 of 10
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that
you would like to pay into the NCWRP. Please note that payment into the NCWRP must be
reviewed and approved before it can be used to satisfy mitigation requirements. Applicants
.will be notified early in the review process by the 401/Wetlands Unit if payment into the
NCWRP is available as an option. For additional information regarding the application
process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If
use of the NCWRP is proposed, please check the appropriate box on page three and provide

1.0 Introduction
Mitchell & Associates, Inc., on behalf of Rocky Carter, has undertaken the project of creating a
mitigation plan for all stream impacts that have occurred on the property located northwest of
Winston Salem, Forsyth County, North Carolina (map 1 a. And 1 b.). The mitigation plan includes
minimizing impacts to Leak Fork Creek to less than 500 linear feet, and relocating the impacted
unnamed tributary to the back of the property. Rosgen steam restoration techniques are to be
used, as outlined in the following plan (Rosgen 1996). Restoration of the impacted streams will
be described in this report and will adhere to the regulations of the U.S. Army Corps of Engineers
(USACOE). This mitigation plan, when implemented, will effectively enhance and restore existing
streams on the project site as well as improve the existing downstream water quality of Leak Fork
Creek.
1.1 Site Description
The property is located on the west side of Patterson Avenue and approximately 1400 feet north
of the intersection of Motor Road in Forsyth County, Winston Salem, North Carolina (Map2).
The site is bounded by route 52 and a Duke Power Right of Way (ROW) located on the west
side. Leak Fork Creek is a shallow tributary adjacent to the property that lies within the valley
parallel to Patterson Avenue on the property's west side . The creek has an average bank to bank
stream width of less than 12 feet, has a north directional flow, and shows channelization further
downstream. (Picturel-4). Evidence of rapid erosion can be seen in several places along the
creek banks, and silt fences were placed in a few areas to help retard the erosion process (picture
5). Green algae (family Chlorophyta) was found growing throughout the bottom of the creek
(picture 6). The surrounding area primarily consists of patches of woody vegetation, numerous
grasses, and small to medium rocks (pictures 7). Trash material was observed along the creek
banks as well as within the water (picture 8). A sewer line runs parallel to Leak Fork Creek and
there is evidence that creek flow was altered due to the placement of the sewer line (picture 9).
The actual site itself has been graded, filled, and is covered with gravel up to its boundaries
(pictures 10 and 11).
1.2 Soil Series Description
The soils located on the property are from the Wehadkee Series and Pacelot Series (Map 3 and
Appendix A). The Pacelot Series consists of Pacelot fine sandy loam and clay loam and can
typically be found on slopes from 10 to 45 percent. These soils are well drained with moderately
slow infiltration and rapid runoff. The Wehadkee Series, in particular Wehadkee loam, is
classified as a hydric soil and characterized as being poorly drained and is located on the flood
plain of streams. Infiltration is moderate and surface runoff is slow. These soils are also subject
to frequent flooding for brief periods of time and can be found on 0 to 2 percent slopes (SCS
1976).
1.3 Vegetative description
Due to the entire site being covered with gravel vegetative data was gathered from immediately
north and south or the property. The overstory consisted of Fraxinus pennsylvanica (green ash),
Populus deltoides (eastern cottonwood), Acer rubrum (red maple), Quercus nigra (water oak),
Quecus phellos (willow oak), Quercus alba (white oak), Pinus taeda (loblooly pine),
Liquadambar styraciflua (sweetgum), Platanus occidentalis ( sycamore), and Liriodendron
tulipifera (yellow poplar). The understory vegetation consisted of native grasses, Eupatorium
cappillifolium (dog fennel), Rosa sp. (Wild rose), andPhytolacca americana (pokeweed).
The following proposed mitigation option was introduced by the U.S. Army Corps of Engineers
to re-establish stream areas on-site and to resolve enforcement matters. This mitigation plan
involves removing a portion of the culvert located in Leak Fork Creek and restoring the area to
natural conditions. In addition , our client will be required to relocate the impacted unnamed
tributary to the back of the property using approved Rosgen techniques. Rosgen techniques
involve analyzing stream characteristics including geomorphic, chemical, biological processes and
there functions. After this data is collected, a stream can be restored to its original condition and
function by imitating its initial state.
2.1 Mitigation procedure
Mitchell & Associates, Inc., has developed the following mitigation plan to resolve the previously
mentioned enforcement matters. Our client will be required to minimize the present 650 linear feet
of impacts to Leak Fork Creek to less than 500 linear feet. This will require approximately 160
linear feet of the creek to be opened, the creek bank re-established, and the placement of
vegetation and root wads along the stream banks for stabilization and erosion control. The
second component of the mitigation plan is related to the impacts associated with the filling of the
unnamed tributary previously located on site. This phase begins with redirecting the culvert
located at the rear of the property east of HWY 52 along the perimeter of the project site. This
redirection will create approximately 1250 feet of meandering stream which will connect with
Leak Fork Creek. Redirecting the stream will provide the streamflow with a cleaner bed, as
opposed to the original which was littered with trash. Detailed below is the methodology and
data associated with implementing this mitigation plan.
2.11. Culvert Removal and Stream Restoration
The culvert located in Leak fork Creek is presently approximately 660 linear feet in length and
begins on the Northern property boundary and ends on the southern property boundary (pictures
12 and 13). This culvert consists of two large pipes that have provided adequate space for high
stream flow. A portion of the culvert (160 ft.) at the southern property boundary end is to be
removed to lessen the culverts length to 500 linear feet or less. After the culvert is removed, this
area of stream will be restored to its previous natural conditions.
Leak Fork Creek can be characterized as a F/G type stream that is undergoing degradation and
widening. This is characterized by the high width to depth ratio and the presents of undercutting
and sloughing of the banks both upstream and downstream of the culverts. The banks are
primarily being stabilized by grass vegetation, shrubs and root material from overstory trees. The
erosion is significant where meanders are present, with undercutting on the outer portion and
sloughing on the inner portion. The width of the channel ranges between 6 and 8 feet while the
bankful width is approximately 10-16 feet. Water depth ranges from 4 inches to 12 inches,
varying according to the presents of pools and rifles.
The previously culverted section of the stream will be restored to a natural state with measures
being undertaken to prevent subsequent erosion. Heavy equipment will be used to remove fill
material and the two pipes in the culvert, during which erosion control measures will be
undertaken to avoid contamination to the creek. This will be in the form of silt fences placed
around the construction areas .
The creek bank will be sloped at a 2:1 angle. This will mimic healthy stream characteristics and
prevent further erosion to downstream areas. The 2:1 slope offers optimal stability with less need
for increased stabilization methods. (MRCS 1998). Bank tops will be given a rounded edge to
form a gradual transition between upland and slope to allow for suitable plant growth. Native
riparian vegetation and root wads will be used for bank stabilization. Root wads with a basal
diameter between 10 to 20 inches from will oaks will be installed using the drive-point method
just above the toe of the slope at ninety degree angles to the direction of water flow. They will be
installed with 1 /3 of the wad below the baseflow elevation. In addition to providing stabilization
the root wads also will impede sediment transport (NCCES 2000). Creek bed material is
available on site and will be consistent with the present bed material which ranges from silt/clay to
cobbles.
2.12 Stream Creation
An unnamed tributary once entered the property from the west from a culvert that extends under
Hwy. 52. This tributary descends approximately 100 feet through a gully from HWY. 52 and
ends at the property line. This stream is narrow (1-2 feet wide), and shallow with a depth of 1
foot. The banks of this tributary are low and at an approximate 1:5 slope. It is bordered by
grassy riparian vegetation and shrubs in addition to oak s and maples. Bed material consists of
silt/clay, cobbles, and boulders.
Our goal is to create a new path for this tributary that will take an approximately ninety degree
turn north at the property line and meander (1000ft) north-east until falling out in a natural area
before reaching Leak Fork Creek. Because much of the flow volume is associated with rain fall
runoff that comes from HWY 52, the natural area will benefit pollution removal before waters
reach Leak Fork Creek. The tributary will have an average depth of 4 feet and a width of 2-4 feet
with low 2:1 sloped banks. The tributary will be located in a 30 foot buffer zone to prevent
contamination and upland runoff from entering.
The first step in creating the new tributary is creating a new path of flow. Heavy equipment will
be used to dig the new stream path. Standard erosion control measures will be undertaken while
work is in progress and vegetative cover is in place.
The slope of the entire tributary will be 2:1 which allows for optimal bank stabilization without
requiring an increase in stabilization procedures. This slope encourages natural plant growth and
impedes sediment transport from occurring (FISRWG 1998). Banks are to be graded and
rounded off, and the soil slightly compacted for planting. Where the 90 degree turn takes place
boulders should be placed at the toe of the slope for times of heavy water flow. Live cuttings of
willow branches will be staked at 2 foot intervals for further stabilization. Additional riparian
planting will take place in the fall for slope stabilization. Both the outside bend and the inside will
be seeded for erosion control and to prevent sloughing.
Sections 2 and 3 of the new tributary, as noted on the map, will be relatively similar in design.
Gradual meanders will be created approximately every 40-50 feet to mimic natural characteristics.
Outside bends will require stabilization in the form of root wads while inside bends will require
only seeding and live plantings. Existing vegetation should be retained to the extent feasible, as
should woody debris and stumps. In addition to providing habitat and erosion and sediment
control, these features provide seed sources and harbor a variety of microorganisms (ref).
Varieties of willows, oaks, and cottonwoods are beneficial vegeatation to be planted on slopes
because they are heavy seeded and fast growing. Live cuttings will be planted to a depth to where
they reach moist soil.
At section 4 the stream will take a northerly turn and fall off into a natural area until reaching
Leak Fork Creek. A berm adjacent to the property line will be constructed to keep water flow
contained on the property. Stabilization of the stream in the bend will imitate the methods used in
the section 1 90 degree turn. The naturalized area should not require any additional seeding or
planting since adequate vegetation is already present.
2.13 Monitoring
Time Frame of project
Below is an outline of the time frame necessary to complete the restoration and stream creation
project. It is our goal to have the 160 foot portion of pipe removed from Leak Fork Creek, bank
slopes laid back properly, and the new channel for the unnamed tributary dug, laid back, and
prepared for planting with in a 45 day time period.
The optimum conditions for successful plant installation are when temperature, moisture, and
sunlight are adequate for germination and establishment. In the eastern United States these
conditions are met beginning in mid winter to early spring. In addition plants should be installed
when dormant for the highest rate of survival. To meet these conditions planting should begin in
November to February depending on weather conditions. These plants will be acquired from a
local commercial source. It is our best estimate that approximately 6,500 plants including willow
oak, green ash, water oak, cottonwood, and black alder will be needed to adequately cover the
lower banks of both the restored section of Leak Fork Creek and the new unnamed tributary.
That number is derived from channel length and bank width with a planting every 2 square feet.
This total achieves 500 trees per sq. Acre.
Mitchell & Associates will implement a site inspection and monitoring plan to ensure the success
of the project. This plan will meet standard procedures for monitoring a project, and include
assurance that the site meets with success criteria for restoration projects.
Within 60 days of completion of mitigation site construction, Mitchell & Associates will submit a
report indicating all work completed and will include: photographs of completed work, the stream
reference reach, longitudinal profiles and cross sections of reference reaches, vegetation sample
plots with locations, and problems encountered and resolved. The location of cross-sections of
reference reaches and vegetative plots are noted on the enclosed map.
Follow up inspections will be conducted on a regular basis and documented in the form of data
summaries and field notes. Sketches, maps, and photographs will be used to document
vegetation development, channel stability, and structure performance.
Vegetation within the buffer zone will be inspected for a period of five years or until success
criteria is met, which ever is the longer period of time. Vegetation will be inspected in August or
September of each year after planting, and at a minimum, no one species should exceed 20
percent of the total number of individuals. Success criteria will be met if, for each of the first
three years after monitoring, a minimum of 320 trees per acre of the planted species have
survived. In years four and five, a minimum of 288 to 260 four year old trees per acre have
survived on the site, and after year five a minimum of 260 five year old trees have survived. If
this vegetation criteria is not met, replanting will take place and the five year monitoring period
will begin again. Vegetation will also be inspected for the presence of exotic, harmful species that
if detected will be removed. Vegetative plots where data is collected will be taken at the 6 areas
noted and labeled on the map.
Stream banks will be inspected 2 times annually during the first two years after project
completion, and one time annually there after for a period of five years. The entire stream
corridor will be inspected to detect areas of erosion or accumulation. Inspection of bank and
channel conditions will be conducted during low water conditions to allow for viewing of
complete structures and channel bed changes. Photo reference sites (longitudinal photos and
lateral reference photos) and reference reach monitoring the reach's cross-section and longitudinal
profiles. Success criteria will be met if, for the period of five years in conjunction with the
vegetation monitoring, the stream Bedford features and cross-sections remain stable. The stream
shall retain its enhanced Rosgen's steam type classification. If any problems are encountered, the
stream channel will immediately be restabilized and planted.
Benthic Macroinvertebrate Monitoring
Benthic macroinvertebrate monitoring will be conducted prior to stream disturbance, and will be
followed up with three years of biological monitoring starting one year after project completion.
Summer is the preferred time for monitoring, hence we will sample in October and again in
February, each year of monitoring activity.
The monitoring will be conducted at four locations. The first location will be at Leak Fork creek,
on the project site where the culvert is to be removed. However, the first sample will be taken
just downstream of where the culvert is located now, due to its presence. The second sample site
will be taken immediately upstream of the property where the unnamed tributary meets the
property boundary. At this pre-project time the unnamed tributary ceases at the project boundary.
Post stream creation the third monitoring site will be located within the center of the newly
created unnamed tributary. A fourth monitoring site will be located 500 feet upstream of Leak
Fork Creek from the property line.
Mitchell & Associates will employ the Qual-4 collection technique for sampling for benthic
macroinvertebrates. This method is accepted for 1 st and 2nd order streams. Four sample types
will be collected at each monitoring area including one kicknet sample, one sweep net sample, one
leafpack, and "visuals". All organisms will be collected and processed.
Written reports containing all relevant information including stream appearance, water quality
data;: and sample results, facts, and figures will be submitted to the DWQ within 30 days after the
find monitoring takes place. Every effort will be undertaken to meet DWQ standards.
e o'er proposed mitigation plan meets USACOE standards and will in fact improve the
=teak Fork Creek and its associated unnamed tributary.

I actually received two copies ...one on October 1 and one on October 4 -
it appears that it was triaged twice, by two different staff members (John
was one, I don't know who the other was...which brings up another point -
not all of the triage staff seem to be using the revised triage form - I
know that I have personnally found it good to know who did the triage, so
if I had a question regarding a comment, I could call them.)
As far as the status of my review - it is on-going. This project is part
of a settlement agreement for an enforcement case and I will also need
Todd's review of the stream restoration.. My guess is that it is going to
go on hold - they didn't even include a map (topo or site map) with the
application.
Talk to you soon,
Jen

DATE: October 5, 2001
SUBJECT: Review of an application by Parker Manufacturing, Inc. for Larry's Homes (site
previously known as PTR, Inc.), Leak Fork Creek, Action ID: 199920144, DWQ No:
011381, Forsyth County
The applicant is requesting 401 Water Quality Certification from the North Carolina Division of
Water Quality. The NCWRC has reviewed information provided by the applicant, and field biologists on
our staff are familiar with habitat values of the project area. These comments are provided in accordance
with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The project is proposed to mitigate for previously unauthorized impacts to Leak Fork Creek and
an unnamed tributary by PTR, Inc. as required under a settlement agreement with the US Army Corps and
the NC Division of Water Quality. The first phase of the project will remove portions of 650 linear feet of
piping impacts on Leak Fork Creek. The second phase will be to create or restore 1250 linear feet of a
previously piped tributary. Rosgen techniques are indicated for the design and construction of both phases.
We believe that it is essential that natural channel designs be based on geomorphic calculations
and reference reaches. This information is not provided in the application. The application also lacks a map
of the site and a plan view of the proposed project activities. These omissions make it difficult to provide
specific comments or recommendations. However, we will not object to the project based on the
description of the work provided by the applicant's consultant as long as state-of-the-art bioengineering
techniques are utilized for restoration design and construction activities.
Thank you for the opportunity to review and comment on this project. If you have any questions
regarding these comments, please contact me at 336/769-9453.
