This Office reviewed the proposed mitigation site for the Lynnhaven II project, an unnamed tributary to
Aho Branch (WS IV, Tr), as shown in your correspondance dated August 15, 2001. The proposed stream
appears to be degraded, appears to have been historically relocated, and currently has little or no buffers. As
such it could be a candidate for restoration. The stream and its riparian buffers would, of course, have to be
preserved in perpetuity.

Watauga County pursuant to revise application filed on the 23rd day of June 1997 to construct the
Lynnhaven II Health Care Facility.
The application provides adequate assurance that the discharge of fill material into the
waters of East Fork of the New River in conjunction with the proposed development will not
result in a violation of applicable Water Quality Standards and discharge guidelines. Therefore,
the State of North Carolina certifies that this activity will not violate the applicable portions of
Sections 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance with

compensatory mitigation may be required as described in 15A NCAC 211.0506 (h) (6) and (7).
For this approval to be valid, you must follow the conditions listed below. In addition, you
should get any other federal, state or local permits before you go ahead with your project
including (but not limited to) Sediment and Erosion control, Coastal Stormwater, Non-discharge
and Water Supply watershed regulations.
Condition(s) of Certification:
1. Appropriate sediment and erosion control practices which equal or exceed those
outlined in the most recent version of two manuals. Either the "North Carolina
Sediment and Erosion Control Planning and Design Manual" or the "North Carolina
¢. " Surface Mining Manual" (available from the Division of Land Resources in the
' DEHNR Regional or Central Offices). The control practices shall be utilized to prevent
exceedances of the appropriate turbidity water quality standard (50 NTUs in all fresh
water streams and rivers not designated as trout waters; 25 NTUs in all lakes and
reservoirs, and all saltwater classes; and 10 NTUs in trout waters);
2. All sediment and erosion control measures placed in wetlands or waters shall be
removed and the natural grade restored after the Division of Land Resources has
released the project;

Introduction
Lynn Hauen 11, LLC d.b.a. Glensione Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the Fsst Fork New River. In response to an application for section
401 certification, the State of Noah Carolina Department of Environment, Health and Natural Resources.
Division of Water Quality (NCDBHNR) has requested " A macrobendws monitoring plan will be neede&for-the
stream. You must monitor the stream at two locations before disturbance, and at two locations for three
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Dorney). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCI)EHN-R.
LOCATION
As stipulated by the NCDEHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast corner of the
property, in the existing stream, below the relocated portion and where the piped section eaters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc- and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well as the following three samplings years.
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. 'These conditions are the most stressful for the aquatic fauna in the stream.

MATERIALS AND METHODS
Techniques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating procedures. Biological Monitoring, Environmental Sciences Branch, Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the benthos survey, sampling techniques for wadable streams will
be utilized. Kidmat, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two ldek samples (>1 ma each), net sweeps ( a minimum of three composite samples), leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, logs, boulders, etc, and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (I-2 organisms),
Common (3-9 organisms); and Abundant. (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 10% fotmalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (MountainiFiedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen, pH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (?Al)
identification number. After cataloging, the samples are rinsed through a 200 micron mesh screen and the
remaining organisms removed from the detritus under SX magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "Picking" through the sample, removing any large orianisms such

as mussels, snails, megalopterans, odonates and representatives of EPT taxa (Ephemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Sputter which splits the sample into 10 subsamples. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the total number of individuals per sample. The organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species keel
in must cases) using available keys and counted. Identifications will be made with a steriomicroscope (7X to
GOX), Slide mounts wiL be made of the chironoraids, simuliids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual, vials in 85% ethanol
(or on glass slides if mounted) labeled by FAI number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including Iota! taxa richness,
EPT taxa richness, and biotic index (using DEl- NR's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EFT taxa and Chironomidae
abundance ratio.

Stream Mitigation Plan
Glenstone Healthcare
Lynnhaven II
Tributary to the East Fork of the New River
Watauga County, North Carolina
Appalachian Environmental Services
March 30, 2001
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the=a$t Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of restoration for the purposes of
mitigation. The remaining 258 feet of stream mitigation will be conducted by the Blue
Ridge RC&D Council in conjunction with the USDA NRCS and the Watauga Soil and
Water Conservation District. Please see Appendix-A for a topographic map of the
project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81°37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 1
I Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength. meander arc length, average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock. washed root
lines, and changes from a steep to gentle bank slope.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of D;. where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.41bs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):
T=yRbfSbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched, high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bank-full discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D;o of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D;o of 16 to 32mm and a Dsa of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T = y Rbr Sbr
Where:,y = 62.4 lbs/ft'
Rbr = Abt/WPbr = 11 ft2 / l Oft = 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbf = .05 ft/ft
Equating to T = 3.43 lbs/ft2
Using the Shield's (Rosgen Modified) diagram (Appendix-B), when the shear stress is
3.43 lbs/ft2 the bankfull event would move particles up to 600mm. which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ground using metal
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 6
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock. As much as possible trees that are on site will be avoided as the
streambanks are altered. On the upper banks we will plant taller growing trees that
provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
{
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the - -
macrobenthos monitoring plan by Pennington and Associates dated August 21, 1997.

Introduction
Lynn Hauen II, LLC d.b.a. Glenstone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet new the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the Past Fork New River. In response to an application for section
401 certification, the State of North Carolina Department of Environment, Health and Natural Resouroes,
Division of Water Quality (NCDEHNR) has requested " A macrobenthos monitoring plan will be-needed-for-the - - -
stream. You must monitor the stream at two locations before disturbance, and at two locations for three
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Dorney). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCDEHNR.
LOCATION
As stipulated by the 1NCDEHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast comer of the
property, in the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc. and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well as the following three samplings years,
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. These conditions are the most stressful for the aquatic fauna in the stream.

MATERIALS AND METHODS
Tbchniques used for the benthic macroiavertebrate survey will follow guidelines set forth in Standard
Operating procedures, Biological Monitoring, Environmental Sciences Branch. Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management. Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the beathos survey. sampling tfttmiques for wadable streams will
be utilized. Kicknet, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>1 ma each), net sweeps ( a minimum of three composite samples), leafpack and
debris collections (one composite sample). epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, logs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Flare (1-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 10% formalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (Mountain/Piedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen. PH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (PAI)
identification number. After cataloging, the samples are rinsed through a 200 micron mean screen and the
remaining organisms removed from the detritus under 5X magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "picking" through the sample, removing any large organisms such

as mussels, snails, megalopterans, odonates and representatives of EPT taxa (Ephemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Sphtter which splits the sample into 10 subsamples. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the cowl number of individuals per sample. T"he organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a sterioronicroscope (7X to
60X). Slide mounts will be made of the chironom ids, simuliids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuhids, and cligochaetes are to be
cleared for 24 hours in cold 1017o KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by FAX number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including Iota: taxa richness,
'?PT taxa richness, and biotic index (using DEHNit`s assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community toss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EPT taxa and Chironomidae
abundance ratio.

as mussels, snails, megalopterans, odonates and representatives of EPT tan (Fphemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which gilits the sample into 10 subsamples. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the total number of individuals per sample. Tle organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic lave' (species level
in most cases) using available keys and counted- Identifications will be trade with a steriomicroscope ('.X to
60X). Slide mounts w111 be made of the chironomids, simuliids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and aligochaetes are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAI number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be anaJyzed trsirtg AEHNR's recommended measures including tots: taxa richness.
EPT taxa richness, and biotic index (using DF.HNR's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector functional
group, ratio of Shredder Functional group and total number of individuals, and EFT taxa and Chironomidae
abundance ratio.

Stream Mitigation Plan
Glenstone Healthcare
Lynnhaven II
Tributary to the East Fork of the New River
Watauga County, North Carolina
Appalachian Environmental Services
March 30, 2001
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the;Ea$t Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of restoration for the purposes of
mitigation. The remaining 258 feet of stream mitigation will be conducted by the Blue
Ridge RC&D Council in conjunction with the USDA NRCS and the Watauga Soil and
Water Conservation District. Please see Appendix-A for a topographic map of the
project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81 °37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.

DWQ # 001095 and COE Action Id. 199702715 Page 1
I Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design - -
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length. average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock. washed root
lines, and changes from a steep to gentle bank slope.
Glenstone Healthcare - Lynnhaven If Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D;o particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

DWQ # 001095 and COE Action Id. 199702715 Page 3
Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):
T = y Rbf Sbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched, high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.

DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist.erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bankfull discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D;o of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T = y Rbf Sbf
Where: y = 62.41bs/ft'
Rbr = Abr/WPbf = 11 ft2 / loft= 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbf = .05 ft/ft
Equating to T = 3.43 lbs/ft'
Using the Shield's (Rosgen Modified) diagram (Appendix-B), when the shear stress is
3.43 lbs/ft2 the bankfull event would move particles up to 600mm, which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank-will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ground using metal
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 6
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock. As much as possible trees that are on site will be avoided as the
streambanks are altered. On the upper banks we will plant taller growing trees that
provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
i
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the
macrobenthos monitoring plan by Pennington and Associates dated August 21. 1997.

Introduction
Lynn Haven 11, LLC d.b.a. Glenstone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County. ,
North Carolina. The stream is a tributary to the Fast Fork New River. In response to an application for section
401 certification, the State of North Carolina Department of Environment, Health and Natural Resources,
Division of Water Quality (NCDEHNR) has requested " A macrobendws monitoring plan will be needed-for the stream. You must monitor the stream at two locations before disturbance, and at two locations for three - -
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Dorney). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCDEHN- R.
LOCATION
As stipulated by the NCDEHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. Tile same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property, The second location will be placed at the southeast corner of the
property, in the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc. and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well as the following three samplings years.
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. 'These conditions are the most stressful for the aquatic fauna in the stream.

MATERIALS AND METHODS
Techniques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating Procedures, Biological Monitoring, Environmental Sciences Branch, Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the benihos survey, sampling techniques for wadable streams will
be utilized. Ficknot, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>i ma each), net sweeps ( a minimum of three composite samples leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum). and visual
collections from macrophytes, logs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (I-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container,-preserved in 10% formaiin and transported to the
Cookeville, Tennessee laboratory for additional proixming.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (MountaiWFiedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen. pH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, inc. (PAI)
identification number. After cataloging, the samples are rinsed through a 200 micron mean screen and the
remaining organisms removed from the detritus under 5X magnification, If the sample contains an abundance of
organisms (>250), it will be processed by first "pickling" through the sample, removing any large organisms such

as mussels, snails, megalopterans, odonates and representatives of EPT taxa (I phemeroptera, Trichoptem and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which splits the sample into 10 subsamples. Subsemples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the total number of individuals per sample. "lire organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a steriomicroscope (?X to
60X). Slide mounts will be made of the chironoraids, sintuiiids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAl number and pertinent project information and archived for a
minimum of 5 years.
'Ilse benthic data will be analyzed using DEHNR's recommended measures including total taxa richness,
EPT taxa richness, and biotic index (using DEHNit's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EPT' taxa and Chironomidae
abundance ratio.

Stream Mitigation Plan
Glenstone Healthcare
Lynnhaven II
Tributary to the East Fork of the New River
Watauga County, North Carolina
Appalachian Environmental Services
March 30, 2001
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the=?a$t Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of restoration for the purposes of
mitigation. The remaining 258 feet of stream mitigation will be conducted by the Blue
Ridge RC&D Council in conjunction with the USDA NRCS and the Watauga Soil and
Water Conservation District. Please see Appendix-A fora topographic map of the
project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81 °37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 1
I Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length, average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root
lines, and changes from a steep to gentle bank slope.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of -
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

DWQ # 001095 and COE Action Id. 199702715 Page 3
Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbt) times the
average bankfull water surface slope (Sbf, ft/ft):
T = y Rbf Sbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched, high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bankfull discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D50 of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T = y Rbf Sbf
Where: y = 62.41bs/ft3
Rbf = Abf/WPbf = 11 ft2 / loft= 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbf = .05 ft/ft
Equating to T = 3.43 lbs/ftz
Using the Shield's (Rosgen Modified) diagram (Appendix-B). when the shear stress is
3.43 lbs/ft2 the bankfull event would move particles up to 600tnm, which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ground using metal
Glenstone Healthcare - Lynnhaven I I Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 6
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock. As much as possible trees that are on site will be avoided as the
streambanks are altered. On the upper banks we will plant taller growing trees that
provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
3
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the
macrobenthos monitoring plan by Pennington and Associates dated August 21, 1997.

Introduction
Lynn Hauen 11, = d.b.a. Glenstone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the East Fork New River. In response to an application for section
401 certification, the State of North Carolina Department of Environment, Health and Natural Resources.
Division of Water Quality (NCDEHNR) has requested " A macrobenthos monitoring plan will be needed-for the
stream. You trust monitor the stream at two locations before disturbance, and at two locations for three-
additional years after the stream has been shoved" (letter dated July 29, 1997 by John R. Dorney). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCDEHNR.
LOCATION
As stipulated by the NCDEHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property, The second location will be placed at the southeast comer of the
property, is the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inn:. and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well as the following three samplings yeam
will be in early September. Ile September season should provide low flow and high temperature conditions in
the stream. 'These conditions are the most stressful for the aquatic fauna in the stream.

MATE-R ALS AND METHODS
Techniques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating Procedures, Biological Monitoring, Environmental Sciences Branch, Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the benthos survey. sampling techniques for wadable streams will
be utilized. Kicknet, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>1 ma each), net sweeps ( a minimum of three composite samples), leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, logs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (I-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 1056 fotmalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (MountaintFiedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen, pH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (PAI)
identification number. After cataloging, the samples are rinsed through a 200 micron mesh screen and the
remaining organisms removed from the detritus under SX magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "picking" through the sample, removing any large organisms such

as mussek, snails, megalopterans, odonates and representatives of EPT taxa (Ephemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which splits the sample into 10 subsamples. Subsampks are randomly selected
and processed completely until a minimum of 250 individuals have been removed. Ibis allows the investigators
to calculate the total number of individuals per sample. The organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species )0%101
in most cases) using available keys and counted. Identifications will be trade with a steriomieroscope (7X to
60X). Slide mounts will be made of the chironorrids, simuli ids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold 1017c KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAI number and pen-went project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including total taxa richness,
EPT taxa richness, and biotic index (using DEHNR's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EFT taxa and Mironomidse
abundance ratio.

Stream Mitigation Plan

Lynnhaven II
Tributary to the East Fork of the New River
Watauga County, North Carolina
Appalachian Environmental Services
March 3 0, 2001
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the;lra$t Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of restoration for the purposes of
mitigation. The remaining 258 feet of stream mitigation will be conducted by the Blue
Ridge RC&D Council in conjunction with the USDA NRCS and the Watauga Soil and
Water Conservation District. Please see Appendix-A for a topographic map of the
project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81 °37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.

I Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length. average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the. controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock. washed root
lines, and changes from a steep to gentle bank slope.
Glenstone Healthcare - Lynnhaven If Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of - -
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di. where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

DWQ # 001095 and COE Action Id. 199702715 Page 3
Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):
T=yRbfSbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched, high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bankfull discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D50 of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T ='y Rbf Sbf
Where: y = 62.41bs/ft'
Rbr = Abt/WPbr = 11 ft2 / loft= 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbe = .05 ft/ft
Equating to T = 3.43 lbs/ft'
Using the Shield's (Rosgen Modified) diagram (Appendix-B), when the shear stress is
3.43 lbs/ft2 the bankfull event would move particles up to 600mm, which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ground using metal
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 6
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock. As much as possible trees that are on site will be avoided as the
streambanks are altered. On the upper banks we will plant taller growing trees that
provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the -
macrobenthos monitoring plan by Pennington and Associates dated August 21, 1997.

On May 13, 1999, a 401 Water Quality Certification was issued to Glenstone Health Care
for impacts to 846 feet of stream. In which the mitigation required was rated at a 1:1
replacement of stream length and forest buffers of approximately 40 feet width on each
side of the stream.
We have now broken this mitigation into three segments. The first is the current on-site
mitigation, second is the previously attempted off-site mitigation, and third is the current
plans for the off-site mitigation.
Current On-Site Mitigation
To double check our measurements and calculations we have asked the members of a NC
Wetlands Restoration Program Mitigation Team, which we are a member, to review our
plans. This will be done as an extra check and balance system before we submit
mitigation and restoration plans to your office.
The current on-site mitigation will consist of restoring 588 feet of stream length to an A2
type stream channel. The following information in conjunction with the current narrative
and restoration plan will answer your questions and concerns listed in your letter dated
March 6, 2001.

• A new map was created for Appendix A. The project location and reference
reaches are located on the map. The reference reach is larger than the stream on
the project site. We also used dimensionless ratios for the design. The length of
the reference reach is 230 feet, which includes two complete sines.
• The entrenchment ratio was recalculated and the reference stream was an A-type.
• The differences in some our numbers on the morphological data sheets are due to
changes in personnel at our company and the subcontractors that we historically
used for drafting. I am now doing the designs and having our WRP team review
the plans before they are submitted.
• The shear stress is 3.43 lbs/ft3. The newly restored channel will have boulders
large enough in size not to be moved by the bankfull event.
• The on-site buffers will be at least 40 feet in width. In some of the upper areas of
the restoration the buffer will be 60 feet. Further, a conservation easement is also
included in Appendix-F of the narrative.
• We have noted in the monitoring plan that all annual reports will be sent to DWQ
for review and comment.
• The culvert is not a part of the restoration project. The culvert was installed by
the neighboring landowner and was not installed during this project.
In summary, the design is based on an A2 type channel. Our previous pebble counts for
riffles actually were conducted in run type habitats. Once this oversight was corrected
the pebble counts were corrected resulting in a correct substrate size for an A2 channel.
Medium boulders with a b-axis greater than 600mm will be used to restore the stream
channel. The information submitted has been checked by numerous stream restoration
consultants for accuracy.
Previously Attempted Off-Site Mitigation
During the previously attempted off-site mitigation, the stream bottom was not degraded
by the restoration efforts. The streambank was stabilized and blanketed with coconut
fiber mats. We have plans, which can be reviewed on pages P3 & P4 of the plan
enclosed dated March 2001, to revegetate these streambanks. Historically, these banks
have been unvegetated due to agricultural uses.
Current Off-Site Mitigation
We have recently worked out a plan with the Blue Ridge Resource & Development
Council, Inc. (Stan Steury - Executive Director), USDA Natural Resources Conservation
Service (Al Childers - District Conservationist) and the Watauga Soil and Water
Conservation District to allow us to pay them for the remaining 258 feet of mitigation
(846 feet of total mitigation minus 588 feet of onsite mitigation). The Blue Ridge
Resource & Development Council and the NRCS currently have projects in the Watauga

involved. If you have any questions please call.

Todd and Dave,
Sorry that it has taken me so long to look at the information. Especially
since I do not see anything that requires any additional comments from me.
They seemed to have hit all of the points that we discussed in our meeting
with Mickey. The only outstanding issue is the off-site, downstream
restoration and the need for a 404/401. I feel that this would be up to
USACE to decide if a 404 is necessary - if they say yes, then a 401 would be
necessary. I really don't think, though, that this is worth pushing the
issue; requiring them to submit a PCN may just cause more of a
hassle ..... for everyone. The main focus is the get the damn stream
restored and if their plan and construction accomplishes that, which it had
better.... great... mission accomplished.
One last thing, I would recommend that they contact us at the beginning of
construction and be made aware of the potential for DWQ compliance
inspections.
Thanks,
Jen

Dear Mr. Readling,
This Office has reviewed the subject stream mitigation proposal. Please be reminded that mitigation credits will not be
given for the downstream section of this project (455 linear feet, off-site) since you are unable to obtain adequate buffers
and a conservation easement. Also, based on the information provided, and field observations the existing channel will
become unstable since the "restoration" was not designed properly. In addition we understand that this reach must be
restored by the landowner. Please describe how you plan to handle this shortfall in stream length. Also you need to
specify how many linear feet of on-site restoration you are hoping to get and how much mitigation will remain. The
proposed stream restoration design seems very similar to the conditions that currently exist in place. We have noted in
three previous correspondences (10 July 2000, 2 August 2000 and 16 November 2000) that this approach is
unacceptable, since it will result in an unstable channel. Again this most recent plan contains numerous vague
descriptions and/or confusing facts that make the review of this document difficult. Please keep in mind that even if the
approach did appear to be valid, insufficient and apparently inaccurate information was provided. Some of reasoning for
our decision is listed below.
? The location of the project and reference reaches illustrated in Appendix A is difficult to determine. Please
locate these stream reaches on a much smaller scale map. Also note that the reference reach needs to be of
similar stream order (reference 16 November letter) and must be stable. The reach used for reference
conditions appeared to be much larger than the subject stream. How long of a reference reach was used for
design and does it meet DWQ requirements for design? Due to this difference in stream size, dimensionless
ratios should be used for design.
? The entrenchment ratio noted in the Morphological Measurements Table suggests that the design is an A4
(not a B4a) and as such would be unstable.
? Data contained in the Morphological Measurements Table are confusing. For example the valley slope is
much less in this reiteration that in previous documents. Changes were also noted for drainage area, bankfull
mean velocity and depth, and others. Are these new calculations from the same reach? Please explain
these differences.
? The consultant's shear stress analyses resulted in 3.74 Ibs/fe. This still appears to be excessive (reference 2
August 2000 letter). We believe that this stress will result in degradation of the channel. He suggests that the
channel will have the competence to move a D84 of 600mm (over 2 feet), and that a D100 of 2048mm (over 6
feet) would not move so that the channel would not degrade. Other than a small outcrop of bedrock, we do
- - - - - - -- - _ -not recall having-observed any boulders of this size in the existing channel. These results suggest that his
proposed grade control is insufficient to maintain stability.
? We still have concerns about the size and permanent protection of the buffers (reference 10 July and 2
August 2000 letters).
? The planting plan as noted on P1 also appears to be vague.
? We recommend noting in the monitoring plan that all annual reports are sent to DWQ for review and
comment.
? Please address, concerns regarding the culvert, specifically how will this structure be designed to allow for
passage of fish?

alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root
lines, and changes from a steep to gentle bank slope.

We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of --
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):
T = y Rbf Sbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched. high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.

DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bankfull discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D;o of 8 to 16mm and a Dsa of 16 to' 2mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T =7 Rbe Sbf
Where: y = 62.4 lbs/ft'
Rbf = Abr/WPV = 11 ft2 / l Oft = 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbr = .05 ft/ft
Equating to T = 3.43 lbs/ft2
Using the Shield's (Rosgen Modified) diagram (Appendix-B), when the shear stress is
3.43 Ibs/ft2 the bankfull event would move particles up to 600mm, which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurrinLy on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and ,voody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ,round using metal
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 6
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock. As much as possible trees that are on site will be avoided as the
streambanks are altered. On the upper banks we will plant taller growing trees that
provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
i
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the - - - - - - - -
macrobenthos monitoring plan by Pennington and Associates dated August-2 1, 1997.

Stream Mitigation Plan
Glenstone Healthcare
Lynnhaven II
Tributary to the East Fork of the New River
Watauga County, North. Carolina
Appalachian Environmental Services
March 30, 2001
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the=Ea$t Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of restoration for the purposes of
mitigation. The remaining 258 feet of stream mitigation will be conducted by the Blue
Ridge RC&D Council in conjunction with the USDA NRCS and the Watauga Soil and
Water Conservation District. Please see Appendix-A for a topographic map of the
project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81°37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.

Introduction
Lynn Hauen II, LLC d.b.a. Glenstone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the Past Fork New River. In response to an application for section
401 certification, the State of North Carolina Department of Environment, Health and Natural Resources.
Division of Water Quality (NCDEHNR) has requested " A macrobenthos monitoring plan will be needed for the
stream. You must monitor the stream at th-o locations before disturbance, and at two locations-for three
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Dorney). Pennington &
Associates, Inc. proposed the following plan to address the needs of the KCDEHNR.
LOCATION
As stipulated by the NCDEHNR, two sites will be selected on the Gleastone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast corner of the
property, is the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc and representatives of Glenstone
Health Care during the first site visit.
DATES
Tice first sampling date, or pre-stream location period, as well as the following three samplings years,
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. These conditions are the most stressful for the aquatic fauna in the stream.

MA1 ERLA LS AND METHODS
1Uhniques used for the benthic macroiavertebrate survey will follow guidelines set forth in Standard
Operating Procedures, Biological Monitoring, Environmental Sciences Branch. Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Envitonment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two !rites selected for the benthos survey, sampling techniques for wadable streams will
be utilized. Kicknet, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>1 ma each), net sweeps ( a minimum of three composite samples}, leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, logs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (1-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 10%, formalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (MountaiNPiedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen. PH and
conductivity. Visual determinations of turbidity will also be recorded.
Iu the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (PAI)
identification number. After cataloging, the samples are rinsed through a 200 micron mesh screen and the
remaining organisms removed from the detritus under 5X magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "picking" through the sample, removing any large otpnisms such

as mussels, snails, megalopterans, odonates and representatives of F.PT' tan (Bphemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepicL and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified water's Sample Splitter which splits the sample into 10 aubsamples. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the total number of individuals per sample. The organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a steriomicroscope (7X to
6OX). Slide mounts will be made of the chironom ids, sintuliids, oligochaetes and small crustaceans, and
identifications made xkith a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAI number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including total taxa richness,
EPT taxa richness, and biotic index (using DEHNR's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector functional
group, ratio of Shredder Functional group and total number of individuals, and EPT taxa and Chironomidae
abundance ratio.

In summary we feel that the design as submitted is not ap,15ropriate for a 134a channel, rakff the consultant needs to
redesign this project for an Al or 2, 131 or 2 channel type.// 4s-would be a more stable channel design for this stream. In
addition, the consultant needs to be aware of, and to incorporate, all comments regarding this project as noted in the
correspondences dated 10 July 2000, 2 August 2000 and 16 November 2000. Ar ? 0J_ -

Dear Mr. Readlin P Q?K?
This Offic as reviewed the subject strea itigation proposal. Plea be reminded that t4er&-w4H4et-fie QUjr mitigation
credits iven for the downstream section of is project (4551inear feet) that this reach must be restore
e i e " ey
p . , a g ) need/to b.-- speci ?' ift how much linear feet of on-site restoration ou
are hoping to get and how much mitigatio will remain. The proposed design seems very similar to the conditions th t
currently exist in place. We have noted in previous correspondence (10 July 2000, 2 August 2000 and a.Wvee ber
2000) that this approach is unacceptableeXas it will result in an unstable channel. yFAgain ?t this 4E contain
numerous vague descriptions and/or confusing facts that make the review of this document difficult. Sonie-et`t4e
Please keep in
mind that even if the approach did appear to be valid, insufficient and apparently inaccurate information was provided.
Some of reasoning for our decision is listed below. JZ.W"
f? .
? The location of the project and reference reaches ill rated in Appendix A is difficult to determine.
IQ ??2 4w_ erdvise?-indicate these locations on a much ' r scale map. Also note that the reference reach needs
VV to be of similar stream order (reference 16 November letter) and must be stable. The reach used for
reference conditions appeared to be much larger than the subject stream. How long of a reference reach was
used for design and does it meet DWQ requirements for design? Due to this difference in stream size
dimensionless ratios should be used for design.
? The entrenchment ratio noted in the Morphological Measurements Table suggests that the design is an A4
(not a B4a) and as such would be unstable. .
? Data contained in the Morphological Measurements Table are confusing. For example the valley slope is
much less in this reiteration that in previous documents. Changes were also noted for drainage area, bankfull
mean velocity and depth, and others. Are these new calculations from the same reach? Please explain
these differences. bZJ;akV
Li The consultant's shear stres analyses resulted in 3.74 lbs/ft3. This still appears to be excessive (reference 2
August 2000 letter). We I that this stress will result in degradation of the channel. He suggests that the
channel will have the competence to move a D84 of 600mm (over 2 feet), and that a D100 of 2048mm (over 6
feet) would not move so that the channel would not degrade. Other than a small outcrop of bedrock, we do
not recall having observed any boulders of this size in the existing channel. These results suggest that his
proposed grade control is insufficient to maintain stability.
? We still have concerns about the size and permanent protection of the buffers (reference 10 July and 2
August 2000 letters).
o The planting plan as noted on P1 also appears to be vague.
? We recommend noting in the monitoring plan that all annual reports are sent to DWQ for review and
comment.
.? Please address concerns regarding the culvert, specifically how will this structure be designed to allow for
passage of fish?

Re: Lynnhaven II, Stream Restoration
Watauga County
DWQ # 970412
Dear Mickey,
Thanks for the Restoration Plan for the Lynnhaven II project in Watauga County. The
approach to this plan is valid; however, it is not supported with necessary information.
Please reference Appendix B of the Draft Technical Guide for Stream Work in North
Carolina for specific details. This document can be accessed through our web site
(htty://h2o.enr.state.nc.us/ncwetlandsn. Specifically we would request that you provide
the precise location of the reference reach and that the cross section, pattern and profile data
for this reach is indicated. Pebble count data and analysis also should be provided. In
addition to this information we also request that you provide the following:
? Please submit data and calculations to show that sediment transport should be a
?o dynamic equilibrium. This should include sediment transport and shear stress
analysis. The "read outs" of any models such as HEC RAS that are used in such
analyses should be provided.
?? Please provide general design details and specifications for any grade control or
bank stabilization structures that shall be used.
ot
? Please provide preliminary site and cross section plans showing the required 25-fo
buffers and planting plan. The plans should show the existing and proposed channe
and features. These plans should be provided on full size sheets and should indicate
proposed locations of structures, grading, etc. to be performed during construction.
? Please provide a construction sequence and estimated time line of the construction
? Also provide some kind of permanent protection for the restored stream and buffer

? Please provide a more detailed monitoring plan for this project. The plan as
presented is inadequate. Please refer to the Technical Guide for Stream Work in
North Carolina and the Benthic Macroinvertebrate Guidance documents for
additional information.
Please be reminded that the 401 certification states that no stream impact shall occur until
written DWQ approval is received for a detailed stream restoration.

CERTIFIED MAIL-RETURN RECEIPT REQUESTED
Mr. Kevin Sabo
Glenstone Health Care
P.O. Box 2210
Boone, North Carolina 28607
Dear Mr. Sabo:
The Division of Water Quality has reviewed the proposed stream mitigation design (July
25, 2000) for the above-mentioned project in Watauga County. The design is inadequate as
presented. Insufficient information has been submitted to determine whether or not the
definition of stream restoration has been met as specified in condition 5 in the 401 Water
Quality Certification for the subject project on 12 May, 1999. Some specific concerns with
the design of this project are listed below.
• The 401 Certification clearly indicates that this plan must assure a 1:1 replacement of
stream length. However, the restoration plan is only for 455 linear feet of stream
channel.
• The shear stress and bankfull velocity (3.9 psf and 14.1 cfs, respectively) in the
proposed restored channel (station 125-455) are still excessive compared to the
reference reach(s).
• The proposed channel and reference reaches are classified as a G4 which are unstable
features and, as such are not acceptable as reference reaches or design channels.
• The morphological characteristic table included with the proposed plan indicates
changes in dimension, pattern and profile; however, the cross sections submitted with
the revised plan do not support these data.
• The design does not have detailed site plans and is therefore very difficult to assess.
Features of the site plan should include the location of the existing and proposed
channel, the location of all stabilization and grade control structures, the location of the
riffle and pools within the restoration channel, and specific planting plans.
• Bankfull bench and the riffles and pools are not shown in the cross sections.
• No conservation easement or means of permanent protection is provided.

• The specific location of the reference reach should be provided for inspection by DWQ
personnel.
Based on the above listed items and recent photos taken by DWQ Regional Office staff, the I
plans do not meet the requirements specified in the 401 Water Quality Certification. *As
such no mitigation credit shall be approved for the stream mitigation plan until these items
are successfully addressed.

Dear Mr. Henson:
Thank you for meeting with DWQ representatives on the 14" of November to discuss the Lynnhaven II
Stream Mitigation project in Watauga County (DWQ # 970412). I believe that the meeting was useful in
that it clearly laid out for all parties involved, a distinct order of events which must be followed. We look
forward to reviewing the revised mitigation plan for this project. I also wanted to summarize some of my
observations of the reference and test streams following this meeting. First of all it was agreed by all DWQ
representatives present that the reach of Racoon Branch that we looked at is not an appropriate reference
reach. This reach clearly was not stable and the stream classification and morphology changed within this
reach. Please be reminded that a reference reach must be of one stream type and must remain stable for at
least two meander wave lengths or twenty (20) bankfull widths (page 13 of the Draft Internal Technical
Guide for Stream Work in North Carolina).
DWQ representatives also revisited the project and conducted a pebble count of the riffles within the lower
reach. These data indicated that the D50 is approximately 22mm not 100mm as noted the mitigation plan
(September 4"). Why is a D50 of 100 mm predicted for design when the current D50 is 22mm? Also it
should be noted that the step-pool system constructed in the restored reach made use of inadequately sized
rock for the steps. Boulders at least 2ft x 3ft x 4ft should be used and proper footing depths should be
provided. Justification for the pool to pool spacing should also be provided using an appropriate reference
reach. For your information the UT to the East Fork of the South Fork of the New River one catchment to
the east of the project appeared to be a very good reference location. Although the stream is larger than the
test site, dimensionless analyses can be done to compare morphological features and to design the restored
stream. Finally, please provide DWQ all previously requested information for this project in the revised
mitigation plan. Once again, we look forward to working with you on this project.
Sincerely,
Dave Penrose

Stream Mitigation Plan
Glenstone Healthcare
Lynnhaven II
Tributary to the East Fork of the New.River
Watauga County, North Carolina
Appalachian Environmental Services
May 25, 2001
7
PROJECT SITE
The stream mitigation for the Lynnhaven II Health Care Facility (DWQ # 970412
and COE Action ID. 199702715) is located on a tributary to the East Fork of the New
River in Watauga County, North Carolina at the intersection of State Roads 1524 and
1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The 401-Certification
required eight hundred forty six (846) feet of stream mitigation. To meet these
requirements Lynnhaven II is proposing 588 lineal feet of on-site restoration for the
purposes of mitigation. Furthermore, the stream will be stabilized to State Road 1524.
The remaining 258 feet of stream mitigation will be conducted by the Blue Ridge RC&D
Council in conjunction with the USDA NRCS and the Watauga Soil and Water
Conservation District. Please see Appendix-A for a topographic map of the project site.
The reference reach is located in a parallel watershed and is located on another
tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81°37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.

3. Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length, average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root
lines, and changes from a steep to gentle bank slope.

DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull'flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with. substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):

The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results -
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as an "A4" type stream. We are proposing restoring the channel into an "A2"
type channel with a step-pool complex. Type "A" streams are single thread channels
with a width/depth ratio less than 12. They are entrenched, high gradient streams with
step/pool features. "A" streams flow through steep V-shaped valleys, do not have a well-
developed floodplain, and are fairly straight.

DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone,
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent.
Bankfull Determination
The data collected relating to bankfull can be reviewed on the Morphological
Measurements Table (Appendix-C). The data measured from the reference reach is listed
on this table. The bankfull discharge was determined from the North Carolina Rural
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
The existing channel has a D50 of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 256 to 512mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T =,y Rbf Sbr
Where: ,y = 62.4 lbs/ft3
Rbf = AbMbf = 11 ft2 / 1 Oft = 1.1 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbf = .05 ft/ft
Equating to T 3.43 lbs/ft2
Using the Shield's (Rosgen Modified) diagram (Appendix-B), when the shear stress is
3.43 lbs/ft2 the bankfull event would move particles up to 600mm, which is greater in size
than the D84 size particle (256-512mm particles or small boulders as indicated on the
Pebble Count for the Reference Reach in Appendix-E). We plan to use medium sized
boulders (with a b-axis over 600mm) and large boulders to construct our steps (riffles).
Further, there is no excessive shear stresses predicted that would result in down cutting.
This can be concluded from the idea that medium sized boulders (with a b-axis over
600mm) and large boulders will not be moved during the bankfull (channel maintaining)
storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
acid vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term. For
temporary erosion control Redtop (Agrostis alba) will be planted.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 _ Page 6
streambed to the top of the streambank and be stapled to the ground using metal
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted in the next dormant season (after November
15). These species will be planted as cuttings or bare rooted stock. As much as possible
trees that are on site will be avoided as the streambanks are altered. On the upper banks
we will plant taller growing trees that provide shade, stable creek banks and wildlife
cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. The buffer will average approximately 40 feet in width on
each side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. Please see Appendix-F for the on-site buffer easement.
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. The annual reports will be sent to
the North Carolina Division of Water Quality. A permanent riffle cross section will be
conducted at Station 4+58. A permanent pool cross section will be conducted at Stations
5+58. A longitudinal profile (indicating thalweg, bankfull and top of bank) and pebble
counts will be conducted annually. Additionally, tree and bush survival rate will be
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-G for the
macrobenthos monitoring plan by Pennington and Associates dated August 21, 1997.

Introduction
Lynn Hauen 11, I.LC d.b.a. Glenslone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the Fast Fork New River. In response to an application for section
401 certification, the State of Notch Carolina Department of Environment, Health and Natural Resources,
Division of Water Quality (NCDEHNR) has requested " A macrobendws monitoring plan will be needed for the
stream. You must monitor the stream at two locations before disturbance, and at two locations for three
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Domey). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCDEHN- R.
LOCATION
As stipulated by the NCDEHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast corner of the
property, in the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc. and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well aS the following three samplings yewm
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. These conditions are the most stressful for the aquatic fauna in the stream. . .
PENNINGTON & ASSOCIATES, INC. Pago 2 August 21, 1997

MATERIALS AND METHODS
Techniques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating procedures, Biological Monitoring, Envirotuaental Sciences Branch, Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the benthos survey, sampling techniques for wadable streams will
be utilized. Ficimet, sweepnet, and visual Collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>1 ma each), net sweeps ( a minimum of three composite samples), leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, logs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (I-2 organisms),
Common (3-9 organisms); and Abundant, (>lA organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 10% formality and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (MountainlPiedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen, pH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Peanittgton & Associates. Inc. (PAI)
identification number. After cataloging, the samples are rinsed through a 200 micron mesh careen and the
remaining organisms removed from the detritus under SX magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "picking" through the sample, removing any large organisms such

Re: Lynnhaven II Detail Changes
Per your request, enclosed is a new Detail Sheet 2 (132) for the Lynnhaven project. We
have omitted the detail for the step-pool sequence and revised the cross-vane detail to be
consistent with page 31 of the Internal Technical Guide for Stream Work in North
Carolina (April 2001, Version 3.0). If you have any questions or comments, I may be
reached at 828-586-1973. Thanks for the assistance.

as mussels, snails, megalopterans, odonates and representatives of EPT taxa (Epherneroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample Is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which splits the sample into 10 subsampies. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the Investigators
to calculate the total number of individuals per sample. The organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a steriomicroscope (7X to
60X). Slide mounts will be made of the chironoraids, sintuliids, oligochaetesand smat) crustaceans, and
identifications made with a compound microscope. The chironomids, simuhids, and oligochaeles are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by P.AI number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzcd u.ing DF-HNR's recommended measures including tots: We richness,
EPT taxa richness, and biotic index (using DEHNIt's assigned tolerance values). Additional co mmunity measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and FYI' taxa and Chironomidae
abundance ratio,

12. (continued) The stream will be diverted into a temporary pipe so that the work, involving
excavation of the alluvium and placement into the relocated stream, can be accomplished in
the dry.
378 if of the southern stream will be piped in a 30"0 aluminum pipe. The pipe is sized
for a 100-year storm event.
14. (continued) Due to the configuration of the lot, streams, and proposed building and parking
and the topography of the land, only one stream could be relocated.
The existing wetlands, where springheads of the southern stream are located, will not be
disturbed by construction. This wetlands will be designated and surveyed as a tract of land
that will never be developed and will remain in perpetuity as wetlands.
The storm water running off the impervious surfaces of the building and parking lot will be
detained in detention structures to prevent storm surge scouring of the bed and banks of the
stream. The detention structures are designed for a 10-year storm event so that the storm
water released into the stream will not exceed the pre-development rate and will be as
follows:
a. The surface water from half of the entrance parking lot will be drained via grassed
swale into a wet detention basin which will discharge the water into the existing
wetlands.
b. The surface water from the other half of the entrance parking lot and the western
half of the building will be detained in a subsurface detention structure and
discharged into the relocated stream.
The surface water from the eastern half of the building will be detained in a
subsurface detention structure and discharged into the existing stream.
d. The surface water from the service road will be drained via a grassed swale into
the wetlands.
e. The surface water from the service parking lot will be drained via a grassed swale
into the stream.
f. The Owner is attempting to purchase the land or a conservation easement for the
flood channel and stream downstream from the property boundary to Bamboo
Road. The Owner plans to stabilize the eroded stream banks and plant native trees
to provide shade for the stream. If the Owner is unable to purchase the land or a
conservation easement, he will contribute to the Environmental Trust Fund, as
recommendation by NCDEHNR, Water Quality Section.

Dear Mr. St. John,
Our staff was at the Lynnhaven Mitigation site yesterday to plug the holes in the cross
vanes. The stream began to flow as a step-pool complex by the time we left the project
site.
On another note, Al Childers (Watauga County NRCS District Conservationist) and I
visited a potential site that he and Stan Steury (Executive Director Blue Ridge RC&D
Council) have selected as the 200 feet of remaining mitigation. The directions and maps
of the potential site are attached to this letter. We were hoping that you could visit this
site when you visit the Lynnhaven site later this month. Again, thank you for all of your
time and assistance with this project.
Sincerely,
f

Directions to Lynnhaven Mitigation Site
The project site is located on 200 to 300 feet of Aho Branch a tributary to the New River
in Watauga County.
Take 321 to Blowing Rock, exit onto Aho Road (1533) proceed approximately 3 miles at
top of hill turn right into Parkway Forest Subdivision. The stream is flowing beside the
first house on the left. The house is being remodeled.

Dear Mr. Grasso:
RE: Lynnhaven H, LLC
Remising 401 Certification questions
Watuaga County
DWQ # 970412, COE # 199702715
The following letter is based on my conversation with Mr. Dave Ramsey (engineer for this
project) on 28 July 1997 regarding the remaining questions that need to be addressed before the
401 Certification can be issued for this project. Until these questions are addressed, this project
will remain on hold due to incomplete information.
1. Relocated stream:
A) Buffers - You will need to provide 50 foot, wooded buffers along each side of
the relocated stream except for the road crossing. This will necessitate removal of the 12 parking
places to the north of the property and perhaps shifting of the site plan itself. This buffer is
needed to ensure the biological viability of the relocated stream.
B) Relocation plan - A specific, detailed site plan for the stream relocation will
need to be provided which shows (via top view) what bioengineering features are planned for the
stream. This plan should include a schedule as well as monitoring (see below) and success criteria.
C) Monitoring - A macrobenthos monitoring plan will be needed for the stream.
You must monitor the stream at two locations before disturbance, and at two locations for three
additional years after the stream has been moved. The Division of Water Quality's standard
biological monitoring procedures shall be followed. Please contact Ms. Trish McPhearson (919-
733-9960) in this regard.
H. Culverted stream: Compensatory mitigation will be needed for the culverting of this
stream. You have expressed a willingness to contribute to the Wetland Restoration Program to
this end. We can "credit' the "extra" 108 feet of relocated stream that you will be creating in this
regard. Therefore you will need to mitigate for the net loss of 270 linear feet of channel at $125
per foot. If you still plan to utilize the WRP in this re ard, we i l send the necessary forms when

0
the 401 Certification is issued.
III. Stormwater: You will need to design a permanent, wet detention stormwater pond or
ponds to treat runoff from the entire site. As I discussed with Mr. Ramsey, your plan to utilize
the existing "wetland/seep" area for stormwater treatment is unacceptable since these wetlands
will be degraded during the treatment of this runoff. You may choose to design the facility to
discharge into the wetland/seep complex after treatment for polishing the runoff and/or if you are
not able to achieve the 85% TSS treatment goal. We will need to receive the stormwater
management plan before the 401 Certification can be issued.
Please call me at 919-733-1786 if you have any questions.

Todd,
I looked over the mitigation reports for McLendon Hills and Southern
Products and Silica. The Southern Products site seems to be doing what
is expected, and will likely be a success if attended to. The McLendon
Hills site doesn't appear to be doing too great. I believe they may be
counting on an improvement in hydrology when the lake fills, and that's
probably some time way off. (There's not much watershed and it's going
to be a deep lake) When it gets to full pool, this place could be much
wetter and plants may have a better chance of survival.

2001 WETLAND MITIGATION
AND RECLAMATION REPORT
FOR
SOUTHERN PRODUCTS AND SILICA, INC.,
HOFFMAN, RICHMOND COUNTY, NORTH CAROLINA
INTRODUCTION
This report, prepared in accordance with State of North Carolina Land Quality Permit No.
77-04 and Water Quality Certification No. 2551, outlines wetland mitigation and monitoring and
reclamation activities at Southern Products and Silica Company, Inc., during 2001.
Southern Products and Silica Company is located directly south of and adjacent to
Drowning Creek, on the west side of U. S. Highway 1, in northeastern Richmond County, North
Carolina (Figure 1). The mine site is located adjacent to forested wetlands, as described in the
permit documentation dated 22 October 1990 by J. H. Carter Ell. Existing trees growing on
wetlands onsite include swamp black gum (Nyssa bi,flora), bald/pond cypress (Taxodium
distichum/ascendens), red maple (Acer rubrum), sweet gum (Liquidambar styraciflua), tulip
poplar (Liriodendron tulipifera), loblolly pine (Pinus taeda), pond pine (Pinus serotina) and
Atlantic white cedar (Chamaecyparis thyoides).
Wetland mitigation activities at the mine in 2001 consisted of supplemental planting and
invasive nuisance vegetation removal within the existing Tyner mitigation area, initial planting
within a newly created mitigation area (Rankin), the collection of annual data from 2 reference
plots and 1 monitoring plot within the existing Tyner mitigation area, and the first annual
collection of data from a new monitoring plot within the new Rankin mitigation area.
Reclamation activities at the mine in 2001 consisted of planting various disturbed upland
and wetland areas.
WETLAND MITIGATION ACTIVITIES
Wetland mitigation activities took place at 2 sites at the mine in 2001, the original
mitigation area (Tyner Lake fan-west) and a newly created mitigation area (Rankin Lake

fan). Activities included planting tree seedlings, nuisance vegetation control and wetland
vegetation monitoring.
PLANTING/NUISANCE VEGETATION CONTROL
Tyner Lake Fan: Wetland vegetation is well established on a majority of Tyner Lake fan.
However, the east side of Tyner Lake fan was expand in .0?1 by filling a portion of the
remaining lake with sand and gravel (Appendix A). Initial plantings were made in this area in
March and April 2001. Planting consisted of approximately 925 bald cypress, 500 swamp black
gum, 450 Atlantic white cedar and 275 pond pine seedlings. Planting methods were similar to
those described in our 1993 report (1993 Reclamation Report--Southern Products and Silica,
Inc., Hoffman, NC, Wilds et al. 1993). The bald cypress, swamp black gum and the pond pine
were planted with 8 - 10 foot spacing between trees. The Atlantic white cedar were planted in
clumps of 3 with 6 - 8 feet between each tree. The species chosen for any particular location was
dependent upon the wetness of the site. A fertilizer tablet was placed with each planted seedling.
Additional plantings of swamp black gum seedlings will be accomplished on the newly
established area on the east side of Tyner Lake fan in January - March 2002. Additional
plantings throughout the original Tyner Lake fan will be made on an as-needed basis.
The planting on Tyner Lake fan as a whole continues to be very successful. Seedlings of
all the planted tree species cotinwe to survive and t a satisfactrate. Many of the
Atlantic white cedar seedlings planted on . e an during earlier years have reached heights of 10
feet or greater. Many produce copious amounts of seed and have created many young volunteer
seedlings of this species. In turn, many of these volunteer Atlantic white cedar seedlings have
survived and continue to grow. The success of other volunteer forbs, grasses, shrubs and trees on
the fan continues to be good. Concurrent to Tyner Lake fan's aging and stabilization, new
herbaceous plant species continue to be identified indicating the ongoing increase in plant
diversity.
Invasive nuisance vegetation ?blolly pine, red maple and sweet gum) as removed on
the Tyner Lake fan during April, July, September and October 2001 (Appendix A). Additional
removal of nuisance vegetation on the Tyner Lake fan will be conducted on an as-needed basis in
2002.
Rankin Lake Fan: A new mitigation area has been created in Rankin Lake (Figure 2 and
Appendix B) with excess sand, gravel and organic muck from the mining operation. Currently,
wash-water is discharged into Rankin Lake and the fan is irregularly flooded. Planting on the
Rankin Lake fan is necessary in order to establish desired vegetation. Initial plantings on this fan
occurred in February and April 2001, when approximately 650 bald cypress, 700 swamp black
gum, 505 Atlantic white cedar and 165 pond pine seedlings were planted (Appendix B). Planting
methods were similar to those described above.
Seedlings planted in February and April 2001 on the Rankin Fan were checked in
September 2001 for survival. It appeared that a majority of the planted seedlings had survived
the growing season. Swamp black gum showed the poorest survival, but many of these have
sprouted back from the rootstock. Seedlings planted within the vegetation monitoring plot (RMP
#2) were mapped and counted in order to track their survival in the future. In September 2001,
there were 32 Atlantic white cedar, 18 bald cypress, 16 pond pine and 17 swamp black gum
within the vegetation monitoring plot which measures 20 meters by 50 meters.
Additional plantings of bald cypress and swamp black gum seedlings will be
accomplished in January - March 2002.
VEGETATION MONITORING ACTIVITIES
Vegetation monitoring plots were established in 1992 in order to monitor the success of
the wetland mitigation activities. A monitoring plot was established in 2 undisturbed wetland
areas adjacent to the mine site (Figure 2). These plots (Reference Forest Ecosystems (RFE))
serve as a reference for the mitigation areas.
In addition to the RFEs, a mitigation monitoring plot (Reclamation Monitoring Plot
(RMP)) was established in the original mitigation area (Tyner Lake fan) in 1992 (RMP #1) and in
the new mitigation area (Rankin Lake fan) in 2001 (RMP #2) (Figure 2).

Reference Plot Data Collection:
RFE#1: Data were collected from all reference plots in September and October 2001.
Dominant tree species in RFE Plot #l, located in an Atlantic white cedar stand (Figure 2),
consisted of white cedar, red maple, sweetbay (Magnolia virginiana) and tulip poplar (Tables 1
and 2). Dominant shrub species were fetterbush (Lyonia lucida), sweet gallberry (Ilex coriacea)
and red bay (Persea borbonia). Dominant herbaceous species were cinnamon fern (Osmunda
cinnamomea) and netted chain-fern (Woodwardia areolata). Dominant non-flowering ground
cover species were peat moss (Sphagnum sp.) and common liverwort (Marchantia polymorpha).
Also noted during this year's monitoring was the continued decline of the isolated
Atlantic white cedar stand in which RFE Plot #1 is located. In addition to the locally
catastrophic snowstorm that occurred in January 2000, this area has been in a drought for 1.5
years. Consequently, the hydrology of this Atlantic white cedar stand has changed - the
underlying water table has declined. This supposition was supported during this year's soil
sampling observations.
In RFE Plot #1, openings in the canopy due to overstory mortality have increased the
natural regeneration of seedlings in some areas. Cinnamon fern has responded in some areas to
the increase in sunlight and seedlings of this species continue to survive and grow. The rare bog
spicebush (Lindera subcoriacea) (module #6, quadrant #4) continues to survive. One new plant
species, a blackberry (Rubus sp.) and 2 new mushrooms (fungi) were noted during this year's
data collection. The blackberry can quickly out-compete more desirable plant species and
become a nuisance. Proliferation of this species will be carefully watched.
RITE #2: Dominant tree species in RFE Plot #2, located in the cypress-gum swamp
adjacent to Drowning Creek (Figure 2), consisted of swamp black gum, red maple and sweet
gum, with evidence of previous dominance by bald or pond cypress from the presence of
numerous stumps (Tables 1 and 3). Dominant shrub species were coastal sweet-pepperbush
(Clethra alnifolia), titi (Cyrilla racemiflora), Virginia sweetspire (Itea virginica) and American
holly (Ilex opaca). Dominant herbs and vines were sedges

(Carex spp.), elongated lobelia (Lobelia elongata), netted chain-fern, crossvine (Bignonia
capreolata) and laurel-leaf greenbrier (Smilax laurifolia). Other ground cover species included
mosses and liverworts.
All of the monitoring data within RFE Plot #2 were collected this year, although many
quadrants were under water (Table 3). Flooding in this plot is quite variable and dependent upon
local precipitation events. Observed vegetative changes in RFE Plot #2 included the continued
decrease in ground cover by mosses, mushrooms, liverworts and young seedlings of most
existing species. The significantly rare sarvis holly (Ilex amelanchier) (module #4, quadrant #1
and module #8, quadrant #1) continues to survive and was observed bearing fruit. Witches'
butter (Tremella mesenterica), a fungus, was also observed in RFE Plot #2 for the first time.
Species composition in the 2 RFE Plots has not shifted significantly during the past 9
years of monitoring. RFE Plot #1 has undergone some cover changes due to a storm event that
occurred in 2000 and a 1.5 year drought.
Mitigation Plot Data Collection:
RMP #1: Data from RMP #1 located on Tyner Lake fan (Figure 2) were collected for the
ninth year in September 2001 (Tables 1 and 4). Planted Atlantic white cedar, swamp black gum,
water tupelo, bald cypress and titi saplings of various ages were present in RMP #1, in addition
to volunteer Atlantic white cedar, tulip poplar, sweet gum, red maple and loblolly pine saplings.
Existing dominant herbaceous species in RMP 41 continue to be largely rushes and sedges
(Juncus canadensis, J. effusus, Scirpus cyperinus and Rhychospora microcephala). Although
still a dominant species, mortality of Juncus spp. continues to increase. Additionally, foxtail
clubmoss (Lycopodium alopecuroides) continues to expand and increase in percent cover at a
very rapid rate. In some modules, this species has continued to out-compete spoonleaf sundew
(Drosera intermedia) and the yellow-eyed-grasses (Xyris spp.). Cover and species diversity
continues to increase in RMP #1, indicating the progression of natural succession and
reclamation success. One new herbaceous vine, a greenbrier (Smilax sp.), and 1 new shrub
species, coastal sweet-

pepperbush, was found. Additionally, a new non-vascular plant species, British soldiers
(Cladonia cristatella), was found with some frequency throughout RMP #1. Plant species
increasing in presence and cover values included planted and volunteer Atlantic white cedar, bald
cypress and titi, tulip poplar, southern blueberry (Vaccinium corymbosum), fetterbush, blackberry
(Rubus sp.), capitate beaksedge (Rhychospora microcephala), southern waxy sedge (Carex
glaucescens), pilose thorough-wort (Eupatorium pilosum), Canada goldenrod (Solidago
canadensis), wrinkleleaf goldenrod (Solidago rugosa), violet (Viola sp.), bladderwort
(Utricularia cornuta), haircap moss (Polytrichum commune), peat moss, and netted chain-fern.
Hypericum spp., Ludwigia spp. and slender goldentop (Euthamia tenuifolia) have decreased in
occurrence.
Species composition in RMP #1 on Tyner Lake fan is gradually changing. The fan now
consists of many herbaceous hydrophytic species with both planted and volunteer shrub and tree
seedlings and saplings. Quantities of many herbaceous species have increased each year due to
natural seeding from existing plants. Plant species diversity on the Tyner Lake fan has also
increased slightly from last year with species in the RMP #1 that also occur within nearby natural
areas. More shrubs and trees continue to colonize the Tyner Lake fan.
RMP #2: Data from RMP #2 located on Rankin Fan (Figure 2) were collected for the
first time in September 2001 (Tables 1 and 5). Planted Atlantic white cedar, bald cypress,
swamp black gum and pond pine were present in RMP #2, in addition to volunteer red maple,
tulip poplar and oak (Quercus sp.). Since this fan was recently created there was very little
herbaceous vegetation. A majority of the RMP consisted of bare ground. The dominant
herbaceous species in RMP #2 was warty panic grass (Panicum verrucosum). Also present were
scattered clumps of wool grass and broom-sedge.
The Rankin Lake fan including RMP #2 is beginning to fill in with early successional
herbaceous vegetation. Tree seedlings were planted throughout the fan and survivability appears
to be good. Herbaceous vegetation will continue to colonize new areas and species diversity will
increase with time.

Soil Sampling: Soil samples were collected from both RFE Plots and RMP #1 in November
2001 and from RMP #2 in December 2001. Hue, value and chroma readings were taken from 6
sites in each RFE Plot, from 8 sites in RMP #1 and 6 sites in RMP #2. Other samples were to be
analyzed for pH, Cu, Zn, Mn, base saturation, P and K. These samples were taken from 3 sites in
each RFE Plot, 3 sites in RMP #1, 6 sites in the area immediately adjacent to RMP #1 and 3 sites
in RMP #2. Samples collected for further analysis were shipped to the Agronomic Division of
the NC Department of Agriculture. Unfortunately, these samples were contaminated, and the
Agronomic laboratory requested that new samples be collected. The analysis of the new soil
samples is currently being conducted and the results of the soil sample analyses will be submitted
as an amendment to this document when they are complete.
RECLAMATION ACTIVITIES
In addition to the wetland mitigation and monitoring, several areas throughout the mine
site are being reclaimed through planting of tree seedlings. These areas include disturbed upland
areas, wetland buffer strips, a clearcut area and an upland buffer strip along U.S. Highway 1.
Upland Areas: Three vegetatively disturbed upland areas (Appendices C and D) were planted
with 2100 longleaf pine seedlings in January, Marchand December 2001. The longleaf pine
trees planted adjacent to the Tyner Lake Fan were spaced 4 - 5 feet apart. A 10 by 10 foot
spacing between trees was used within the other 2 upland reclamation areas. A fertilizer tablet
was placed with each planted seedling.
Invasive nuisance vegetation (loblolly pine) was removed within the upland reclamation
area southwest of Rankin Lake (Appendix D) during September and December 2001. Additional
removal of nuisance vegetation within upland reclamation areas will continue as necessary.
Wetland Buffer Strips: Existing vegetation within 2 extant wetland buffer strips (Appendix E)
were augmented with 150 swamp black gum, 50 bald cypress, 60 Atlantic white cedar and 100
pond pine seedlings in April 2001. The swamp black gum, bald cypress and the pond pine were
planted with 8 - 10 foot spacing between trees. The Atlantic white cedar were planted in clumps
16
c e
of 3 with 6 - 8 feet between each tree. The species chosen for any particular location was
dependent upon the wetness of the site. A fertilizer tablet was placed with each planted seedling.
Additional plantings will be made as necessary.
Wetland Clearcut Area: A clearcut area north of Rankin Lake (Appendix F) was planted in
April 2001 in order to reclaim this area with desired vegetation. Approximately 75 bald cypress,
400 swamp black gum and 100 pond pine seedlings were planted in this wetland area in April
2001 (Appendix F). Planting methods were similar to those described above. Additional
plantings will be made as necessary.
US Highway 1 Roadside: An upland buffer strip along US Highway 1, adjacent to active
mining operations, was augmented with 35 live oak (Quercus virginiana) seedlings in April 2001
(Appendix Q. Individual trees were planted approximately 20 feet apart within a long narrow
strip. A fertilizer tablet was placed with each planted seedling. Additional plantings will be
made as necessary.
SUMMARY
The wetland mitigation and reclamation activities for Southern Products and Silica
Company are proceeding as prescribed in the approved reclamation plan (Carter & Associates
1989). Two reference monitoring plots and 2 mitigation monitoring plots have been established
and are being monitored. The mitigation areas Tyner Lake fan and Rankin Lake fan have been
planted with the prescribed plant species. Survivorship is being monitored and seedlings are
being replaced as necessary.
In addition, several areas throughout the mine site are being reclaimed by planting.

WETLANDS MITIGATION
2001 ANNUAL REPORT
MOORE COUNTY, NORTH CAROLINA
INTRODUCTION
The McLendon Hills Subdivision, located in Moore County, North Carolina, will impact
8.8 acres of jurisdictional wetlands during creation of a 75-acre lake and associated dam. In
order to mitigate for this loss; McLendon Hills created 2 acres of wetlands, preserved ,10.2 acres
of wetlands on-site,,and protected 32.4 acres of wetlands through restrictive covenants on the
1roperty,s -This report, prepared in accordance with North Carolina Water Quality Certification
3209 (DWQ Project #980247) and U.S. Army Corps of Engineers (ACOE) Action ID #
199801001, outlines wetlands mitigation and monitoring activities that took place at McLendon
Hills during 2001.
Mitigation activities at McLendon Hills in 2001 consisted of planting hydrophytic
vegetation and collecting data from groundwater monitoring wells and vegetation monitoring
plots.
PROJECT SITE
McLendon Hills is located north of N.C. Highway 211, approximately 1 mile west of
Seven Lakes, Moore County, North Carolina (Figure 1). Logging in 1995 removed 95% of the
overstory vegetation on the property which consisted of longleaf pine (Pinus palustris), loblolly
pine (Pinus taeda) and southern red oak (Quercus falcata). Currently, successional species such
as sweetgum (Liquidambar styraciflua) and loblolly pine dominate the property, as well as
understory species such as blackjack oak (Quercus marilandica) and flowering dogwood
(Cornus florida).
The overstory vegetation of the impacted wetlands was dominated by loblolly pine, pond
pine (Pinus serotina), sweetgum, red maple (Ater rubrum), tulip poplar (Liriodendron tulipifera)
and swamp blackgum (Nyssa biflora). The shrub layer was dominated by highbush blueberry
(Vaccinium corymbosum), sweet pepperbush (Clethra alnifolia) and titi (Cyrilla racemiflora).
V 1K
Ground cover was dominated by cinnamon fern (Osmunda cinnamomea) and catbriers
(Smilax spp.).
PROPOSED MITIGATION
The mitigation plan for McLendon Hills (previously known as Equestrian Lakes) was
prepared by Land Management Group, Inc. (1996). Mitigation activities were turned over to Dr.
J.H. Carter III & Associates, Inc., in late 1999 and the 5-year monitoring period began on the
first day of the wetland vegetation planting, 5 January 2000. Mitigation activities include
installation of groundwater monitoring wells, planting of hydrophytic vegetation and vegetation
monitoring. Mitigation activities occurred at 2 created sites at McLendon Hills (Figure 2). Site
#1 is 1.5936 acres in size and Site #2 is 0.239 acres in size.
As defined in the mitigation plan, the mitigation will be considered successful when the
hydrologic regime of the 2 created mitigation sites is comparable to wetland reference sites and
when a minimum of 320 hydrophytic trees/acre (including volunteer species) survive for 3 years
(Land Management Group Inc. 1996). The goal is to create wetland hydrology within the
mitigation areas (Well 1-Site 1 and Well 1-Site 2) (Figure 3). Criteria for wetland hydrology are
met when the areas are inundated or saturated to the surface (within 12 inches) for at least 12.5%
of the growing season (28 days in most years). The growing season for Moore County, North
Carolina runs from late March to early November (approximately 228 days).
MITIGATION ACTIVITIES
On 11 January 2001, hydrophytic tree saplings were planted at both of the created
mitigation sites. At Site 1, 100 tulip poplar and 100 swamp blackgum seedlings were planted 10
to 12 feet apart. At Site 2, 50 tulip poplar and 50 swamp blackgum seedlings were planted 10 to
12 feet apart.
MONITORING ACTIVITIES
Monitoring Wells
Four groundwater monitoring wells were installed by Land Management Group Inc. on
23 July 1997, 1 in each mitigation site and 1 in a wetland reference area adjacent to each

mitigation site (Figure 2). The wells are programmed to take water level readings every 12 hours
and data are downloaded every 3-4 months.
Water elevations for the period 1 January 2001 through 31 December 2001 are displayed
graphically in Appendices A and B. Well 1-Site 1 is located at an elevation of 532.9 feet above
mean sea level (MSL). Well data show that the water level at this well fluctuates between 529.5
and 532.1 feet MSL (Appendix A.1). In order for this site to be considered a wetland the water
level must rise above 531.9 feet MSL for at least 28 consecutive days during the growing season.
The water level at Well 1-Site 1 rose above 532.0 feet MSL on several days, but did not remain
there for more than 1 day at a time. The reference well at Site 1 is located at an elevation of
544.5 feet MSL and well data show that the water level remains near the surface throughout the
year (Appendix B.1).
Well 1-Site 2 is located at an elevation of 540.62 feet MSL. The graph shows that the
water level at Well 1 fluctuates between 537.5 and 540.0 feet MSL (Appendix A.2). The water
level at this well did rise above 539.62 feet MSL for at least 28 consecutive days during the
growing season and so the criteria for wetland hydrology was met. The reference well at Site 2
is located at an elevation of 541.93 feet MSL and well data show that the soil was not saturated
within 12 inches of the surface for 28 days. The water level rose over 541 feet several days
throughout the growing season, but did not remain there for more than a day (Appendix B.2).
Vegetation Monitoring Plots
Vegetation monitoring plots were established in September 2000. One vegetation
monitoring plot was established in a reference wetland at each of the 2 sites and 3 vegetation
monitoring plots were established in each of the 2 created mitigation areas. The vegetation plots
are 1/1 00th acre in size. Plot centers were marked with permanent rebar and have a radius of
11.8 feet. The vegetation in each plot was characterized by species, prevalence and percent
cover (see Appendices C and D for complete species lists).
The monitoring plots in the mitigation area at Site 1 were dominated by grasses, rushes,
sedges and weedy annuals (Appendix C, Tablel and Figures 5 and 6). Plot 1 was dominated by
wool-grass (Scirpus cyperinus) and bare ground, with lesser amounts of weak rush (Juncus
debilis) and Canada rush (Juncus canadensis) (Table 1 and Figure 5). Plot 2 was dominated by
bare ground with a very sparse vegetative cover including broom-sedge (Andropogon

(Hypericum gentianoides), cypress witchgrass (Panicum dichotomum) and willow-leaf
goldenrod (Solidago stricta) (Table 1 and Figure 5). Plot 3 had a moderately dense cover of
grasses, rushes and sedges. Dominant species were clustered beakrush (Rhynchospora
cephalantha), with scattered small-fruit spikerush (Eleocharis microcarpa), hairy umbrella sedge
(Fuirena squarrosa), red-pod rush (Juncus trigonocarpus), warty panic grass (Panicum
verrucosum) and wrinkled goldenrod (Solidago rugosa) (Table 1 and Figure 6).
The reference plot near Site 1 was dominated by a dense cover of shrubs and small trees
including red maple, red chokeberry (Aronia arbutifolia), sweet pepperbush, tulip poplar,
sweetbay (Magnolia virginiana), loblolly pine and catbrier (Table 2 and Figure 6).
The mitigation area at Site 2 was also dominated by grasses, rushes, sedges and weedy
annuals (Appendix C, Table 1 and Figures 7 and 8). Dominant species at Plot 1 were hairy
umbrella sedge, red-pod rush and wool-grass, with lesser amounts of red chokeberry, sweet
pepperbush, twisted spikerush (Eleocharis tortilis), hairy thorough-wort (Eupatorium pilosum),
warty panic grass and clustered beakrush (Table 1 and Figure 7). Open water also dominated
Plot 1. Hairy umbrella-sedge, warty panic grass and bare ground dominated Plot 2 (Table 1 and
Figure 7). Other common species within Plot 2 included broom-sedge, small-fruit spikerush,
dangleberry (Gaylussacia frondosa) and red-pod rush. Plot 3 was dominated by open water,
wool grass and broom-sedge (Table 1 and Figure 8), with lesser amounts of dog fennel, round-
leaf thorough-wort (Eupatorium rotundifolium) and hairy umbrella sedge.
The reference plot at Site 2 was dominated by a dense cover of shrubs and small trees
including red maple, red chokeberry, sweet pepperbush, inkberry (Ilex glabra), tulip poplar,
bayberry (Myrica heterophylla), swamp blackgum and swamp azalea (Rhododendron viscosum).
Cinnamon fern was the dominant groundcover (Table 2 and Figure 8).
Soil Samples
Soil samples were taken with a soil auger at each vegetation monitoring plot in order to
determine if the soils within the mitigation areas were developing hydric soil characteristics.

RESULTS AND DISCUSSION
A majority of the swamp black gum and tulip poplar planted at Site 1 in 2001 survived
the growing season. Currently at Site 1 there are approximately 480 hydrophytic seedlings
including 248 pond pine and 58 swamp blackgum planted in 2000 and a majority of the swamp
blackgum and tulip poplar planted in 2001.
At Mitigation Site 2 a majority of the swamp black gum and tulip polar planted in 2001
survived the growing season. Currently at Site 2 there are approximately 100 hydrophytic
saplings including 48 pond pine planted in 2000 and the swamp black gum and tulip poplar
planted in 2001.
Survival goals for the mitigation are 320 trees/acre surviving at 3 years, including
volunteer species (Land Management Group Inc. 1996). At Site 1, 509 saplings are required
after 3 years, but only 480 saplings are present after 2 years. Additional plantings will need to be
made at Site 1 in order to meet the mitigation goals. At Site 2, 77 saplings are required after 3
years. Currently there are 100 saplings. The saplings at this site will be monitored closely and
additional plantings made if there is a significant change in numbers.
Wetland hydrology criteria have not been met at Site 1. Water levels have risen to within
1 foot of the surface on several days, but have not remained there. Wetland hydrology criteria
have been met at Site 2. The water level at Site 2 has risen to within 1 foot of the surface for
more than 28 consecutive days during the growing season.
Average annual rainfall for Moore County is 49 inches (USDA 1995). The rainfall total
for Moore County for 2001 as reported at the Carthage Water Treatment Plant (State Climate
Office of North Carolina) was 32.07, well below the average. The below average rainfall
amounts contribute to the lack of wetland hydrology within the Mitigation Site 1.
A majority of the species found within the mitigation monitoring plots were hydrophytic
species (Table 1). Presently these sites are dominated by herbaceous vegetation. Shrubs and
trees are present, but will need to increase in cover to resemble the reference areas.
A majority of the soil samples taken within the mitigation area exhibited hydric soil
characteristics (saturated, oxidized root charnels etc.)(Table 3). Plot 2 at Site 2 did not have
hydric soil characteristics.

SUMMARY
The mitigation activities for McLendon Hills are proceeding as prescribed in the
Mitigation Plan (Land Management Group 1996). Wetland vegetation was planted in each
mitigation site and additional plantings are planned for 2002. Water level readings are being
downloaded every 3-4 months from the 4 monitoring wells. Eight vegetation monitoring plots
were revisited and data were collected at each.

PROJECT SITE
The stream mitigation for Glenstone Health Care's Lynnhaven II Health Care
Facility (DWQ # 970412 and COE Action ID. 199702715) is located on a tributary to the
East Fork of the New River in Watauga County, North Carolina at the intersection of
State Roads 1524 and 1656 (N35° 11.672' W83°50.195' on the WGS84 Datum). The
401-Certification required eight hundred forty six (846) feet of stream mitigation. To
meet these requirements Glenstone Health Care is proposing 1,043 lineal feet of
restoration for the purposes of mitigation. Five hundred and twenty (588) lineal feet of
stream was relocated and restored and four hundred and fifty five feet (455) of existing
stream channel was restored. Please se ppendix-A fo topographic map of the

tributary to the East Fork of the New River in Watauga County, North Carolina (N36°
11.136' W81°37.671' on the WGS84 Datum). Please see Appendix-A for a topographic
map of the reference reach.
SCOPE
The objective of this stream restoration project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel based upon reference reaches.
2. Create correct habitat types within the stream channel.

DWQ # 001095 and COE Action Id. 199702715 Page 1
3. Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.
CHANNEL RESTORATION
Methods
Meander Design
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length, average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root
lines, and changes from a steep to gentle bank slope.
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 2
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

Shear Stress
Since boundary shear stress is the most appropriate measure of the forces driving
erosion, graphs have been developed for allowable shear stress. The average boundary
shear stress (T, lbs/ft2) acting on an open channel conveying a uniform flow of water is
given by the product of the unit weight of water (Y, 62.4 lbs/ft) times the bankfull
hydraulic radius (bankfull area, Abf divided by bankfull wetted perimeter, WPbf) times the
average bankfull water surface slope (Sbf, ft/ft):
T=YRbfSbf
The diagram used to determine the maximum size particle moved during the bankfull
flow is a Shield's curve of the threshold of motion modified by Dave Rosgen during the
October, 2000 Level 4 Restoration Workshop (Appendix-B).
Results
In the past, the stream has been straightened and channelized. Currently the
stream is down cutting and the riparian vegetation is minimal. The current channel is
classified as a degraded "B" type stream. We are proposing restoring the channel into a
"134a" type channel with a step-pool complex. Type "B" streams are wider than "A"
streams and have a broader valley but a well-developed flood plain. These single thread
streams are moderately entrenched with moderate to steep slopes. Type "B" stream are
usually dominated with step-pool sequences. The high width/depth ratios and moderate
entrenchment ratios make this stream type resilient to watershed changes.

DWQ # 001095 and COE Action Id. 199702715 Page 4
Step-Pool Complex
A Step-Pool habitat can improve bank stability in an incised channel by reducing
bank heights. Man-made pools downstream of steps can provide improved aquatic
habitat. Rock steps will be placed across the channel and anchored in the streambanks to
provide a hard point in the streambed that resist erosion forces of the degradational zone, t
and to reduce the upstream energy slope to prevent bed scour. The stones used for the
steps will be embedded into the streambed 10 to 15 percent. / l ?•t ?'• v.a?
Bankfull Determination t4 ??
j4tle
The data collected relating to bankfull can be reviewed on the Morphological t S 'fir , Measurements Table (Appendix-C). The data measured from the reference reach is listeddfI
? G
on this table. The bankfull discharge was determined from the North Carolina Rural
G,
Mountain Regional Curve (Appendix-D) as supplied by the NC Cooperative Extension ?(
Service. Further, the Bankfull Area, Depth and Width measured at the reference site
were confirmed by these regional curves.
Particle Size Distribution
7
The existing channel has a D50 of 8 to 16mm and a D84 of 16 to 32mm. The
reference reach has a D50 of 16 to 32mm and a D84 of 64 to 128mm. The raw data from
the pebble counts for the existing and reference reaches may be viewed in Appendix-E.
Shear Stress
Using the equation for shear stress:
T = 7 Rbf Sbf
Where: y = 62.4 lbs/ft3
Rbf = Abf/WPbf = 12ft2 / l Oft = 1.2 ft
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 5
Sbf = .05 ft/ft
Equating to T - .74 lbs/ft2 ?c
Using the Shield's (Rosgen Modified) diagram pendix-B), when the shear stress is
3.74 lbs/ft2 the bankfull event would move particles up to 600mm, which is greater in size
than the D84 size particle (64-128mm particles or small cobble as indicated on the Pebble
Count for the Reference Reach in Appendix-E). Further, there is no excessive shear
stresses predicted that would result in down cutting. This can be concluded from the ide SE_ ?(•
that the D1oo size particle (2048mm) will not be moved during the bankf ill (channel
maintaining) storm event.
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
This process will increase cross-sectional area. Coconut blankets will be pinned into the
bank for short-term (4 years) stabilization. The blankets will stabilize the streambank
long enough for the vegetation to root and stabilize the stream for the long-term.
RIPARIAN RESTORATION
Historically, the riparian area consisted of grass. After the streambank is sloped it
will be seeded with native herbaceous and woody plant. Seeded sections of the bank will
be covered with coconut fiber blankets. These blankets will protect the area from the
streambed to the top of the streambank and be stapled to the ground using metal
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or

bare rooted stock during the next dormant season. As much as possible trees that are on
site will be avoided as the streambanks are altered. On the upper banks we will plant
taller growing trees that provide shade, stable creek banks and wildlife cover and food.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative P9 so we will only bousima! ve species t

revegetate the riparian zone. he buffer will range from 20 to 40 feet in width on eac
side of the stream channel. The buffer will be planted with a minimum of 400
trees/bushes per acre (native species). The survival rate after 5 years will be 320 trees per
acre. A selection of the following species will be used at this site: Arrowhead (Sagittaria
latifolia), Pickerelweed (Pontederia cordata), Cardinal Flower (Lobelia cardinalis), Soft
Rush (Juncus effuses), Henry's Garnett (Itea virginica), Dog Hobble (Leucothoe
fonianesiana), Buttonbush (Cephalanthus occidentalis), Silky Dogwood (Corpus
amomum), Black Walnut (Juglans nigra) and Sycamore (Platanus occidentalis).
MONITORING
Physical Monitoring Plan
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. A permanent riffle cross section will
be conducted at Station 8+83. A permanent pool cross section will be conducted at
Stations 5+88. A longitudinal profile (indicating thalweg, bankfull and top of bank) and
pebble counts will be conducted annually. Additionally, tree and bush survival rate will
be monitored in a manner that demonstrates a survival rate of 320 trees per acre. Species
Glenstone Healthcare - Lynnhaven II Stream Mitigation
DWQ # 001095 and COE Action Id. 199702715 Page 7
survival will consist of checking each individual plant. Plants will be checked for overall
condition and health. A report will be prepared with the previous information.
Macrobenthos Monitoring Plan
Pennington and Associates will conduct the macrobenthos monitoring. A benthic
macroinvertebrate survey is recommended to assess long-term water quality conditions of
the small tributary. Basic water chemistry and habitat assessments will also be conducted
during the benthic macroinvertebrate survey. Please review Appendix-F for the
macrobenthos monitoring plan by Pennington and Associates dated August 21, 1997.
Please review Appendix-G for the Pre-Restoration Monitoring conducted by Pennington
and Associates on September 9, 1997.

Introduction
Lynn 11auen 11, LLC d.b.a. Glenstone Health Care proposes to relocate 4'70 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the Fast Fork New River. In response to an application for section
401 certification, the State of North Carolina Department of Environment, Health and Natural Resources,
Division of Water Quality (NCDEHNR) has requested " A mawobenthos monitoring plan will be needed for the
stream. You must monitor the stream at two locations before disturbance, and at two locations for three ?
additional years after the stream has been moved" (letter dated July 29, 1997 by John R. Dorney). Pennington
Associates, Inc. proposed the following plan to address the needs of the NCDE.HNR.
LOCATION
As stipulated by the NC I)EHNR, two sites will be selected on the Gleastone Health Care property for
monitoring prior to oonstmction and relocation. The same sites will also be utilized for the three years after the
stream relocation. it is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast corner of the
section enters the existing
property, in the existing stream, below the relocated portion and where the piped
stream. Specific locations will be selected by Pennington & Associates, Inc. and representatives of Glenstone
Health Care during the first site visit.
DATES
The first sampling date, or pre-stream location period, as well as the #ollowiAg three samplings y
id
will be in early September. The September season should provide low flow and high temperature oondons in
the stream. These ouditions are the most stressful for the aquatic fauna in the stream.

MATEpjALS AND METHODS
Toclamiques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating procedures, Biological Monitoring, Environmental Sciences Branch. Ecosystems Analysis Unit.
Biological Assessment Group, North Carolina Department of Environment. Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the beathos survey. sampling techniques for wadable streams will
be utilized. KiO met, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>l W each), net sweeps ( a minimum of three composite saru&4 leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections from macrophytes, togs, boulders, etc. and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (1-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 101Y* fotmalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
physical characteristics to be determined at each site include substrate composition (weatworth Scale),
width, depth, velocity. flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (Mountain/Piedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen, pH and
conductivity. Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (PAI)
identification number. After catalogin& the samples are rinsed through a 200 micron mesh screen and the
remaining organisms removed frow the detritus under SX magnification. If the sample contains an abundance of
organisms (>250), it will be processed by first "picking" through the sample, removing any large organisms such

as mussels, snatiK megalopterans, odonates and representatives of Eff tans (Fphemeroptera, Trichoptera and
plecoptera) that were missed during the field pick. This portion Of the sample is referred to ati a prep" and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which splits the sample into 10 subsamples. Subsampks are randomly selected
and processed completely until a minitttum of 250 individuals have been removed. This allows the investigators
to calculate the total number, of individuals per sample. 'lire organists are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a steriomicroscope OX to
604 Slide mounts wiD be made of the chironomids, sirnuiiids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold Me KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mourns were desired, the organisms will be transferred to 95%
ethanol for 30 minutes and mounted in euperol. All species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by FAA number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including total taxa richness,
EPT taxa richness, and biotic index (using DEHNEVs assigned tokrance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jaccard coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EPT taxa and Chironomidae
abundance ratio.

INTRODUMON
Lyme Haven II, LLC d.b.a. Glenstone Health Care proposes to relocate 470 feet of
existing stream to the northeast property boundary and pipe 378 feet near the southern portion
of their property in Watauga County, North Carolina. The stream is a tributary to the East
Fork New River. In response to an application for section 401 certification, the State of
North Carolina Department of Environment, Health and Natural Resources, Division of Water
Quality (NCDEHNR) has requested "A macrobenthos monitoring plan will be needed for the
stream. You must monitor the stream at two locations before disturbance, and at two
locations for three additional years after the stream has been moved" (Letter dated July 29,
1997 by John R. Dorney). This survey was the first of four accomplished by Pennington &
Associates, Inc. to address the needs of the NCDEHNR. The macroinvertebrate survey was
conducted on September 9, 1997 by Wendell Pennington of Pennington & Associates, Inc.
The objectives of the study was to determine physio-chemical and benthic macroinvertebrate
community characteristics of the small stream.
Since macroinvertebrate populations are more indicative of the relative health of a
stream, attention was focused on this group. Macroinvertebrates are found in all aquatic
habitats, they are less mobile than most other groups of aquatic organisms, such as fish, they
are easily collected, and most have relative long periods of development in the aquatic
environment. Thus, macroinvertebrate species should reflect deleterious events that have
occurred in the aquatic environment during any stage of their development.

LOCATION
As stipulated by the NCDEHNR, two sites were originally selected on the Glenstone
Health Care property for monitoring prior to construction and relocation. During the site visit
it was determined to do a third. The same sites will be utilized for the remaining three years
after the stream relocation (Figure 1). The control station is located at the northwest corner
of the property where the existing stream enters the property. The second location was to be
placed at the southeast corner of the property, in the existing stream, below the relocated
portion and where the piped section enters the existing stream. Because of stream
channelization in the confluence of the mainstream and the proposed piped portion by the
adjacent tree farming operations, Station 2 was located just up stream of the confluence.
Station 3 was situated in the mouth of the stream section to be piped.

BACKGROUND
As found in other similar studies, the alteration of the physical and/or chemical norms
of an aquatic environment has the potential to influence all organisms residing in that
environment (Goodnight 1973). A community represented by numerous species with no
particular numerical domination evident in the population is usually indicative of an
unstressed environment (Weber 1973). Conversely, a benthic community composed of a few
species with large numbers of individuals typifies a stressed community from which intolerant
species have been reduced or eliminated by a pollutant or substrate change. The populations
of tolerant species expand due to reduced competition or increased resources, or both. The
often dramatic shifts in the benthic community which can occur under stressed conditions are
due to the varying sensitivities of the different macroinvertebrate species. Mayflies
(Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera), are generally less
tolerant of most types of pollution and are considered intolerant or sensitive species, whereas
many flies (Diptera) and worms (Oligochaeta) are more tolerant of environmental stress
conditions (Brinkhurst 1962, Beck 1977, Mason 1971, and Merritt and Cummins 1996).
Stream reaches may be divided into several ecological categories depending upon whether or
not they are subject to stressful agents and, if they are, to what extent or type; they can
usually be divided on the basis of the benthic fauna that is supported in that reach.
Clean water streams with variable habitat features often have a high diversity of
species with no species numerically dominant. Streams receiving organic pollution generally
show a decrease in both taxa richness and diversity and an increase in density (Gaufin and
Tarzwell 1956), while streams receiving toxic products frequently show a decrease in taxa
PENNINGTON & ASSOCIATES, INC. Page 4 LYNI 197.WPD November 5, 1997
richness, diversity and density (Cairns et al., 1971).
Increased sedimentation in streams is a problem most often the result of poor
agriculture practices, construction activity and mining in the vicinity of the streams. The
effects of increased sedimentation are varied, but the primary effect is scouring during high
flows, habitat loss caused by the filling of cracks and crevices with sand and silt and general
decrease in habitat diversity.
Attention is usually focused on the macroinvertebrate species because they are more
indicative of the relative health of a stream. In addition, macroinvertebrates are found in all
habitats, are less mobile than other groups of aquatic organisms, are easily collected, and
most have relatively long periods of development in the aquatic environment. Thus,
macroinvertebrate species can be used to indicate deleterious events that have occurred in an
aquatic system during any stage of their development.

MATERIALS AND METHODS
Sampling techniques used for the benthic macroinvertebrate survey in the small
tributary to East Fork New River followed guidelines set forth in Standard Operating
Procedures, Biological Monitoring, Environmental Sciences Branch, Ecosystems Analysis
Unit, Biological Assessment Group, North Carolina Department of Environment, Health and
Natural Resources, Division of Environmental Management, Water Quality Section, January
1997 (pages 3-17). Sampling techniques for wadable streams were utilized at each of the
three sites selected for the benthos survey. Kicknet, sweepnet, and visual collecting
techniques were used to collect the benthic samples. At each location , because of the small
size of the stream, two kick samples (10 each) in the slow and fast portion of the riffle/run,
leafpack and debris collections (one composite sample: 200 micron mesh), epifaunal
collections (combined with leafpack and debris collections), and visual collections from
macrophytes, logs, boulders, etc. were collected. All samples were screened in the field with
a 200 micron mesh net and field picked (enumerations limited to Rare, 1-2 organisms,
Common 3-9 organisms; and Abundant, >10 organisms). The remaining samples were
placed in plastic containers, labeled on the inside and outside of the container, preserved in
10% formalin and transported to the Cookeville, Tennessee laboratory for additional
processing.
In the laboratory, the samples were cataloged by assigning a Pennington & Associates,
Inc. (PAI) identification number. After cataloging, the samples were rinsed through a 120
micron mesh screen and the remaining organisms removed from the detritus under 5X
PENNINGTON & ASSOCIATES, INC. Page 6 LYN1197. WPD November 5, 1997
magnification. If the sample contains an abundance of organisms (>250), it was processed by
first "picking" through the sample, removing any large organisms such as mussels, snails,
megalopterans, odonates and representatives of EPT taxa (Ephemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick and visual collection for that habitat. This
portion of the sample is referred to as a prepick and is processed with the field pick and
visual collection. After the sample was prepicked the remaining sample was split using a
modified Water's Sample Splitter which splits the sample into 10 subsamples. Subsamples
were randomly selected and processed completely until a minimum of 250 individuals were
removed. This allowed the investigators to calculate the total number of individuals per
sample. The organisms were transferred to 85% ethanol after removal from the debris. The
individuals were identified to the lowest practical taxonomic level (species level in most
cases) using available keys and counted. Identifications were made with a steriomicroscope
(7X to 60X). Slide mounts were made of the chironomids, simuliids, oligochaetes and small
crustaceans, and identifications made with a compound microscope. The chironomids,
simuliids, and oligochaetes were cleared for 24 hours in cold 10% KOH. Temporary mounts
were made in glycerine and the animals returned to 80% ethanol after identification. When
permanent mounts were desired, the organisms were transferred to 95% ethanol for 30
minutes and mounted in euperol. All species are retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAI number and pertinent project information and
archived for a minimum of 5 years.

SUBSTRATE DETERMINATION
A classification of substrate based on the size scale proposed by Wentworth (Compton
1962) was used to make field observations of the substrate present at each station. This
classification of detrital sediments is by grain diameter and is as follows:
Diameters Approximate Inch
Equivalents
>256 mm
64 to 256 mm
2to64mm
1/16 to 2 mm
1/256 to 1/16 mm
<1/256 mm
>10 inch
2.5 to 10 inch
0.08 to 2.5 inch
0.002 to 0.08 inch
0.00015 to 0.002 inch
<0.00015 inch

Brower and Zar (1984) provide a detailed discussion of a variety of techniques for
measuring community structure. The use of diversity indices is based upon the observation
that normally undisturbed environments support communities with large numbers of species
having no individuals present in overwhelming abundances. If the species of a disturbed
community are ranked by numerical abundance, there may be relatively few species with
large numbers of individuals. Mean diversity is affected by both "richness" of species (or
abundance of different species) and by the distribution of individuals among the species.
High species diversity indicates a highly complex community.
PENNINGTON & ASSOCIATES, INC. Page 8 LYNI 197.WPD November 5, 1997
Species diversity was estimated using:
Shannon's Index of Diversity
d = -Y-p; log p;
Where p; is the proportion of the total number of individuals occurring in species i
(p;=n/N), N is the total number of individuals in all species.
Diversity indices take into account both the species richness and the evenness of the
individuals' distribution among the species. Separate measures of these two components of
diversity are often desirable. Taxa richness can be expressed simply as the number of species
in the community. Evenness may be expressed by considering how close a set of observed
species abundances are to those from an aggregation of species having maximum possible
diversity for a given N and s (Brower and Zar 1984).
Evenness is calculated using:
Pielou J' = H/H,n?
Community similarity between sites is measured by Jaccards Coefficient, Community
Loss Index, and Percent Similarity.
Jaccard Coefficient = C
S-S2-C
S = Species in each community (S, is reference Community in Community loss Index)
C = Species common to both communities
Community Loss Index Sj- C
=
S2
The Community Loss Index is an index of dissimilarity with values increasing as the
PENNINGTON & ASSOCIATES, INC. Page 9 LYN1197.WPD November 5, 1997
degree of dissimilarity from the reference station (Sj increases (Plafkin et al. 1989). Values
range from 0 to infinity.
Percent Similarity, for a two-community comparison, is calculated as follows: The
number of individuals in each species is calculated as a fractional portion of the total
community. The value for species i in community 1 is compared to the value for species i in
community 2. The lower of the two is tabulated. This procedure is followed for each
species. The tabulated list (of the lower of each pair of values) is summed. The sum is
defined as the Percent Similarity of the two communities.
The percent contribution of the numerically dominant taxon to the total number of
organisms in the community is a rough measure of community balance at the lowest possible
taxonomic level (Plafkin et al. 1989). A community which is dominated by a few species
may be under environmental stress.
The total number of species within the pollution sensitive groups Ephemeroptera,
Plecoptera, and Trichoptera is generally considered a measure of water quality and is listed as
the EPT Index (Plafkin et al. 1989). The EPT Index generally increases with increasing water
quality.
In North Carolina, taxa richness for Ephemeroptera + Plecoptera + Trichoptera (SEPT)
is calculated and SEPT is used to assign a biological classification of Excellent, Good,
Good/Fair, Fair and Poor. The standard score for piedmont areas in North Carolina is as
follows:

According to Plafkin et al. (1989) the scraper and filtering collector ratio (Sc/FC)
reflects the riffle/run community food base and may provide insights into the nature of
potential disturbance factors. The ratio of scraper abundance to the combined totals of
scrapers and filtering collectors (Sc/Sc+FC) is an adjustment of the scrapers / filtering
collectors from a ratio to a measure of percent contribution (Barbour et al. 1992).
The ratio of shredder functional feeding group and total number of individuals
(Sh/Total) in the CPOM sample, allows evaluation of potential impairment as indicated by the
shredder community. Shredders are considered sensitive to riparian zone impacts and are
believed to be good indicators of toxic effects when toxicants are absorbed by or associated
with the course particulate organic matter (CPOM) (Plafkin et al 1989).
The EPT and Chironomidae abundance ratio (EPT/Chironomidae) is the relative
abundance of the pollution sensitive groups Ephemeroptera, Plecoptera, and Trichoptera to the
more tolerant Chironomidae as a measure of community balance (Plafkin et al. 1989). It is
believed that good biotic condition is reflected in benthic communities with an even
distribution of species among all four major groups and with substantial representation of
Ephemeroptera, Plecoptera, and Trichoptera. Populations with a disproportional number of
Chironomidae relative to the sensitive groups is most likely an indication of environmental
stress (Plafkin et al. 1989).
PENNINGTON & ASSOCIATES, INC. Page 11 LYN1197.WPD November 5, 1997
The percentage of Hydropsychidae abundance to total Trichoptera (Barbour et al.
1992) is an additional metric to evaluate the benthic macroinvertebrate riffle/run communities.
The Hydropsychidae / Trichoptera is the measure of the relative abundance or contribution of
the generally mild pollution-tolerant family, Hydropsychidae, to total Trichoptera.
Arctopsyche and Parapsyche are not to be included in the analyses.
A scoring approach developed by Plafkin et al. (1989) to estimate community health
utilizes many of the community measures previously discussed. This rapid bioassessment is
presented in flow chart format in Figure 2.
Habitat was assessed using North Carolina Habitat Assessment Field Data Sheets for
Piedmont and Mountain Streams adapted from the Rapid Bioassessment Protocols (Plafkin et.
al. 1989). Habitat was scored in reference to the upstream reference site.
BIOTIC INDEX
Both evenness and diversity indices are based on information of community structure
and do not reflect any knowledge of the physiological attributes or ecological affinities of the
organisms comprising the community (Howmiller and Scott 1977). Howmiller and Scott
(1977) suggest the use of a trophic index for assessing ecological stress using Oligoehaete
species. After a two-year study of 53 Wisconsin streams, Hilsenhoff (1982) proposed using a
biotic index of arthropod populations as a rapid method for evaluating water quality.
Hilsenhoff (1987) expanded and improved his biotic index and this index, which is a measure
of organic and nutrient pollution, was used in this study.
To calculate the Hilsenhoff's Biotic Index, species are assigned pollution tolerance
values of 0 to 10. A value of 0 is assigned to species found only in unaltered streams of very
PENNINGTON & ASSOCIATES, INC. Page 12 LYN1197.WPD November 5, 1997
high water quality, and a value of 10 is assigned to species known to occur in severely
polluted or disturbed streams. Intermediate values are assigned to species that occur in
streams with intermediate degrees of pollution or disturbance. Where species cannot be
identified, genera are assigned values instead. The Hilsenhoff Biotic Index is calculated from
the formula:
B.I.. n a
N
Where n; is the number of individuals of each species, a; is the tolerance value
assigned to that species and N is the total number of individuals in the sample (Hilsenhoff
1982). The index is an average of tolerance values, and measures saprobity (pertaining to
tolerance of organic enrichment) and to some extent trophism.
According to Hilsenhoff (1987) the calculated Biotic Index values reflect the following:
Biotic Index Water Quality Degree of Organic Pollution
0.00 -3.50 Excellent No apparent organic pollution
3.51 -4.50 Very Good Possibly slight organic pollution
4.51 -5.50 Good Some organic pollution
5.51 -6.50 Fair Fairly significant organic pollution
6.51 -7.50 Fairly Poor Significant organic pollution
7.51 -8.50 Poor Very significant organic pollution
8.51 -10.00 Very Poor Severe organic pollution
To calculate the biotic index for aquatic benthic macroinvertebrates from the Small
tributary the investigators used tolerance values provided in North Carolina Department of
Environment, Health and Natural Resources, Division of Environmental Management Water
Quality Section, Standard Operating Procedures Biological Monitoring, Environmental
PENNINGTON & ASSOCIATES, INC. Page 13 LYN] 197.WPD November 5, 1997
Sciences Branch Ecosystems Analysis Unit, Biological Assessment Group, January, 1997
(North Carolina, Department of Environment, Health and Natural Resources 1997).
The biotic index values for each location were calculated using two techniques. First,
the biotic index values were calculated with North Carolina's assigned taxa abundance values
(1=Rare, 1-2 specimens; 3=Common, 3-9 specimens; and 10=Abundant >10 specimens)
using the following formula:
En;Q,
Biotic Index =
N
where n; = ith taxa's abundance value (1, 3, 10), a; = ith taxa's tolerance value, and N = sum
of all abundance values. The second way biotic index values were calculated was to use the
actual abundance values enumerated for each species from all samples.
North Carolina provides water quality classifications for EPT and Biotic Index values
based on three geographic regions (mountains, piedmont and coastal). It was deemed more
appropriate by the investigators to assign values for the Mountain region. North Carolina's
scoring criteria for water quality assessment is as follows:
EPT Values NC Biotic Index (Mountain) Water Quality
>35 < 4.05 Excellent
28-35 4.06-4.88 Good
19-27 4.89-5.74 Good - Fair
11-18 5.75-7.00 Fair
0-10 > 7.00 Poor
PHYSICAL AND CHEMICAL PARAMETERS
PENNINGTON & ASSOCIATES, INC. Page 14 LYNI 197.WPD November 5, 1997
The physical and field chemical parameters measured included pH, dissolved oxygen,
temperature, conductivity, total hardness, and stream width and depth. Velocity was taken
with a Gurley Flow Meter. PH was determined at each station with a Fisher Acument Field
pH Meter. Dissolved oxygen was determined with a YSI model 51 Dissolved Oxygen Meter.
Temperature was taken with a field centigrade thermometer. A LaMotte Conductivity Meter
was used to measure conductivity and a LaMotte Field Kit was used to measure total
hardness. Width and depth of the stream bed was taken at each station with a meter stick.
PENNINGTON & ASSOCIATES, INC. Page 15 LYN] 197.WPD November 5, 1997
RESULTS AND DISCUSSION
Physical characteristics and water quality data of the three stations are listed in Table
1. A list of all species of aquatic benthic macroinvertebrates, assigned tolerance values and
functional feeding groups from each stations are shown in Table 2. A summary of benthic
macroinvertebrate community measures is presented in Table 3 and metrics for a Rapid
Bioassessment Protocol III procedure determined from these community measures are shown
in Table 4 (Station 1 as a control site). All field data including habitat assessment field data
sheets are presented in the Appendix.
In terms of physical habitat for aquatic life, the stations rated similar scores with 68
at Station 2, 75 at Station 1 and 87 at Station 3. The lower score indicates least desirable
habitat. The streams were very small, narrow and shallow (Table 1). Substrate at all
locations consisted mostly gravel and cobble. The flow was low, less that 0.5 feet per
second.
Water quality information presented in Table 1 indicates pH neutral to slightly acidic,
(6.21 to 6.62) at all stations. Conductivity, Total Dissolved Solids and hardness
measurements were at or below detectable limits. Temperature ranged from 12.8-13.9 °C at
all stations. Dissolved oxygen ranged from 7.40 mg/1 at Station 2 to 8.75 mg/1 at Station 1.
The water was clear at all stations when sampled.
The three stations support a diverse benthic macroinvertebrate community within the
study reach. A minimum 77 species of macroinvertebrates were collected from all sites
(Table 2) during the September 9, 1997 survey. Chironomids were the numerically dominant
PENNINGTON & ASSOCIATES, INC. Page 16 LYN1197.WPD November 5, 1997
group in the benthic communities at all stations. Station 1 had a minimum of 48 species (18
EPT); Station 2, 49 (25 EPT); and Station 3, 51 (18 EPT). In terms of density, using all
collecting techniques, Station 1 yielded 2670 individuals/2m2; Station 2, 3161/2m2 and Station
3, 4322/2m2.
The most often used community measures for interpreting benthic data by North
Carolina Department of Environment, Health and Natural Resources Biological Assessment
Group includes total taxa richness (species richness), taxa richness for Ephemeroptera +
Plecoptera + Trichoptera (SEPT), Biotic Index using all species and assigned abundance
values (Rare = 1, 1-2 specimens; Common = 3, 3-9 specimens; and Abundant = 10, ?10
specimens), and Biotic Index of SEPT using assigned abundance values. The total taxa
richness for all stations ranged from 48 at Station 1 to 51 at Station 3. In terms of EPT taxa
richness, the control station (Station 1) and Station 3 both had 18 while Station 2 had the
most at 25. Using North Carolina's SEPT criteria for mountain areas of the state, Stations 1
and 2 are considered indicative of "Fair" water quality while Stations 2 scored "Good to
Fair". Scoring criteria for total Biotic Index values, using North Carolina's assigned
abundance values, places all stations as existing under "Excellent" water quality conditions.
If actual abundance numbers are used in the calculation of the Biotic Index values for each
station, all stations again score as "Excellent".
The summary of diversity values listed in Table 3 indicates that the populations at all
stations are very diverse (4.80 at Station 1 to 3.78 at Station 2) and, according to Weber
(1973), representative of communities existing under good water quality conditions. The
diversity value reflects the distribution of individuals among the species where an even
PENNINGTON & ASSOCIATES, INC. Page 17 LYNI 197. WPD November 5, 1997
distribution of individuals among species would yield the maximum diversity value and the
restriction of individuals to a few species would produce a low diversity value. A reduction
of the diversity value can result when species have been eliminated from the environment
either as a direct result of perturbations or by increased competition with other species whose
survival has been enhanced. A reduction in diversity can also result from an abundance of a
few species in the community. An example of a perturbation would be organic enrichment
where species that have wide tolerances (dissolved oxygen, temperature, pH, etc.) would have
a greater chance of survival than species that have a narrow range of tolerance or very
specific requirements. The survival and development of the tolerant species would be further
enhanced if the organic enrichment increased that tolerant species food source, either by
direct consumption or by increasing the growth of periphyton if the tolerant species is a
periphytic feeder. Other factors that may increase the number of tolerant species could be
reduced competition by elimination of other less tolerant species which may use the same
food source or by removing a predator species which may use the tolerant species as a food
source. Increased organics in a system may also change the substrate, either directly or
indirectly favoring species that build cases in soft substrate over those that require a hard,
more stable substrate. Increased siltation is another factor which may alter the substrate and
contribute to a reduction of habitat diversity.
The evenness values shown in Table 3 were 0.60 or greater at all stations. According
to Weber (1973), values of eqitability between 0.6 to 0.8 are representative of streams in the
southeast considered unaffected by oxygen demanding wastes.
PENNINGTON & ASSOCIATES, INC. Page 19 LYN1197.WPD November S, 1997
When a Rapid Bioassessment Protocol III scoring criteria (Table 4) is applied to a set
of defined metrics (Figure 2), using Station 1 as a reference site (Table 4), Station 2 would be
considered slight to non-impaired while Station 3 would be considered nonimpaired. The
moderately impaired status of Station 2 is a reflection of an increase in the number of
chironomids at the site.

Memorandum To: Dave Penrose
From: Todd St. John
Subject: Lynnhaven II
Watauga County
Dave, I have reviewed the latest stream mitigation design for the subject project dated
February 14, 2001. Based on the data provided by the consultant I make the following
recommendations:
1) The consultant is contending that the design stream will be a 134a. The given entrenchment ratio
suggests that the design would be a A4 which is an inherently unstable stream type. In any event
based on the data and his proposed typical for a "step", I do not believe that there is any
expectation that the stream would stable. In fact, I do not see much difference between what the
consultant has proposed and what he already put in the ground, -which based on our observations
is clearly inadequate. I also noticed that the existing valley slope seems to have become less
steep, 10% to 5%, since the last time I reviewed his plans? This makes me question the data that
the consultant is producing.
2) The consultant's own shear stress analysis suggested a shear stress of 3.74 Ibs/sgft. His
suggestion that this is not excessive is at best questionable. He suggests that the channel will
have the competence to move a D84 of 600mm (over two feet), and that a D100 of 2048mm (over
6ft) would not move so that channel would not degrade. Other than a small outcrop of bed rock
(see sheet 1-2), 1 do not recall having observed any boulders of this size in the existing channel.
Also, the largest particle in his pebble count other than bedrock is supposedly less than 256mm. I
do not agree at all with his conclusions and believe that such high shear stresses would result in
degradation. Also, based on his typical for a step, there is no reason to expect that such a
structure could withstand these shear stresses. In other words, his proposed grade control is
completely insufficient to maintain grade, in my opinion.
In conclusion, I think that there is no way to tweak this design to make it work. I think the consultant
needs to "go back to the drawing board."

Memorandum To: Dave Penrose ?
From: Todd St. John
Subject: Lynnhaven II /? ??'
Watauga County
? i -
I have reviewed the most recent submittal for the proposed stream restoration
design: _ <--L
1) The shear stress and bankfull velocity (3.8 psf and 14.1 cfs, respecively) in the
proposed restored channel (station 125-455) are still excessive compared to the
reference reach(s). Therefore, the design is currently unacceptable. _
2) The applicant has indicated that the existing channel is classified as an A5, an
unstable stream form. The proposed channel and reference reach are classified as
G4, also an unstable channel form. This does not make sense.
3) The morphological characteristics table indicates changes in dimension, pattern and
profile. The cross sections submitted do not support these data. `-,sue
4) The site plan is very unclear. No site details are given. The existing channel is not
show, as such it is impossible to determine what changes to pattern will actually be
made. In this case, the applicant should be made to show very detailed site plans
including the location of the existing and proposed channel, the location of all
stabilization and grade control structures. The locations of riffles and pools. A
specific planting plan.
5) Bankfull is not shown on cross sections. Pools and riffles are not indicated on cross
sections.
6) No easement or means of permanent protection is provided.
There are many other issues that may be related to lack of detail and lack of clarity.
Basically, the whole design is inadequate as presented. Insufficient information has been
submitted to determine whether or not the definition of stream restoration has been met.
The whole submittal is so unclear, it is difficult to provide any comments. As such, I
recommend that we reject the stream restoration plan.

Stream Mitigation Plan
For Glenstone Health Care
(Lynnhaven II)
Tributary to the East Fork of the New River
Watauga County, North Carolina
Mickey B. Henson
Principal Hydrologist
Appalachian Environmental Services
May 23, 2000
PROJECT SITE
The stream mitigation for Glenstone Health Care's Lynnhaven II Health Care
Facility is located on 455-feet of a tributary to the East Fork of the New River. The
mitigation site is located directly below the construction site of the Lynnhaven II facility
in Watauga County, North Carolina. (N35° 11.672' W83°50.195' on the WGS84
Datum). The reference reach is located on Raccoon Branch, which flows parallel to
Teaberry Hills Road in Watauga County, North Carolina (N36° 11.059' W81°37.455' on
the WGS84 Datum). Please see Appendix-A for photographs of the existing project
location and photographs of the reference site. Please see Appendix-13 for a topographic
site maps for the project and reference sites and stream restoration map. Please see
Appendix-F for copies of the CWA 401 Certification and Erosion Control Permit from
the Watauga County Department of Planning and Inspections.
SCOPE
The objective of this stream mitigation project is to improve the water quality,
riparian quality and stability of this stream. Long-term stabilization will be accomplished
by stabilizing the riparian area with native vegetation. Specific objectives for the project
are as follows:
1. Construct a new stream channel base upon reference reaches.
2. Create correct habitat types within the stream channel.
3. Stabilize the bankfull elevation along the reach.
4. Slope and vegetate the streambanks so they are more resistant to flooding.
5. Plant native trees, bushes and ground cover that will stabilize the streambanks, shade
the stream, and provide wildlife cover and food.

CHANNEL RESTORATION
Methods
Meander Design
The approach used results in an average channel slope being determined by
meander geometry (meander wavelength, meander arc length, average width at bankfull,
meander amplitude, radius of curvature and arc angle). These approaches are based on
the assumption that the controlling factors in the stream channel (water and sediment
inputs, bed material gradation, and bank erosional resistance) will be similar to those in a
selected reference reach (either the restoration reach before disturbance or undisturbed
reaches). If the reach targeted for restoration is closely bounded by undisturbed
meanders, dimensions of these undisturbed reaches may be studied for use in the restored
or created reach.
Bankfull Determination
Visual identification of bankfull flow on large streams in alluvial bottoms is
relatively easy. However, small streams in the Southern Appalachians rarely have
alluvial bottoms. Smaller mountain streams seldom develop distinctive topographic
breaks between the bank and the floodplain common in larger streams and rivers.
Therefore, bankfull flow was estimated by observing vegetation, bare rock, washed root
lines, and changes from a steep to gentle bank slope.
We have experienced that the best indicators of bankfull flow in the Southern
Appalachians tend to be signs of repeated erosion and cleansing of banks and deposition
on point bars. Storms larger than bankfull can erode the stream banks and mask the
indicators. In the Southern Appalachians, the vegetation line is probably the most
Appalachian Environmental Services Page 2
difficult indicator to use to determine bankfull depth. Riparian vegetation in the
mountains withstands high flows and may even revegetate quickly into the bankfull area.
This is especially true with certain types of mosses. Some of the problems of
determining reliable indicators of bankfull flow stem from the stream banks being
undercut and caving in.
Particle Size Distribution
Particle size data are usually reported in terms of Di, where I represents some
nominal percentile of the distribution and Di represents the particle size, usually
expressed in millimeters, at which i percent of the total sample by weight is finer. For
example, 50 percent of the total sample would be finer than the D50 particle size. For
estimating size distribution in steep mountain streams with substrate much coarser than
the medium-gravel limitations of Federal Interagency Sedimentation Project (FISP)
samplers, a pebble count, in which at least 100 bed material particles are manually
collected from the streambed and measured, is used to measure particle size. At each
sample point along the cross section, a particle is retrieved from the bed, and the
intermediate axis is measured. The measurements are tabulated as to number of particles
occurring within predetermined size intervals, and the percentage of the total number in
each interval is then determined. Again, the percentage in each interval is accumulated to
give a particle size distribution, and the particle size data are reported as described above.

Reference (Small Tributary to Raccoon Branch)
The restored stream channel will be patterned after the reference reach. The
restored channel has a meander wavelength 40 feet, meander arc length 56 feet, meander
amplitude of 15 feet, radius of curvature of 20 feet, arc angle of 7 degrees, steps should
be restored every 3 to 5 feet, water surface slope of 2-4%, and a D50 of 40mm in pools
and 90mm in riffles, bankfull velocity is 8.2 cfs and the shear stress at bankfull is 1.5 psf.
Reference (Raccoon Branch)
The restored stream channel will be patterned after the reference reach. The
restored channel has a meander wavelength 50 feet, meander arc length 61 feet, meander
amplitude of 15 feet, radius of curvature of 20 feet, arc angle of 7 degrees, steps should
be restored every 5 to 7 feet, water surface slope of 24%, and a D50 of 50mm in pools
and 100mm in riffles, bankfull velocity is 13.8 cfs and the shear stress at bankfull is 1.2
psf.
Restored (Stations 0-125)
The restored stream channel will be patterned after the reference reach. The
restored channel has a meander wavelength 40 feet, meander arc length 56 feet, meander
amplitude of 15 feet, radius of curvature of 20 feet, arc angle of 7 degrees, steps should
be restored every 3 to 5 feet, water surface slope of 24%, and a D50 of 40mm in pools
and 90mm in riffles, bankfull velocity is 8.2 cfs and the shear stress at bankfull is 1.5 psf.
Restored (Stations 125-455)
The restored stream channel will be patterned after the reference reach. The
restored channel has a meander wavelength 50 feet, meander arc length 61 feet, meander
amplitude of 15 feet, radius of curvature of 20 feet, arc angle of 7 degrees, steps should
Appalachian Environmental Services Page 5
be restored every 5 to 7 feet, water surface slope of 24%, and a D50 of 50mm in pools
and 100mm in riffles, bankfull velocity is 14.1 cfs and the shear stress at bankfull is 3.8
psf. \
STREAMBANK STABILIZATION
Above the bankfull elevation the streambank will be sloped to the top of the bank
and vegetated. This feature benefits the stream by slowing water velocity during high
water events. This in turn reduces the amount of erosion occurring on the streambanks.
Cross-sectional area will be increased by this process (see Appendix-C for existing,
restored and reference cross sections). Coconut blankets will be pinned into the bank for
short-term (4-years) stabilization (see Appendix-D for construction diagrams). The
blankets will stabilize the streambank long enough for the vegetation to root and stabilize
the stream for the long-term.
RIPARIAN RESTORATION
After the streambank has been sloped it will be seeded with native herbaceous and
woody plant seeds described on the following native plant list. Seeded sections of the
bank will be covered with coconut fiber blankets. These blankets will protect the area
from the streambed to the top of the streambank and be stapled to the ground using metal
landscape staples. Low growing woody species such as Henry's Garnett, Silky
Dogwood, and Buttonbush will be planted. These species will be planted as cuttings or
bare rooted stock during the next dormant season. As much as possible trees that are on
site will be avoided as the streambanks are altered. On the upper banks we will plant
taller growing trees that provide shade, stable creek banks and wildlife cover and food.
Appalachian Environmental Services Page 6
The desires of the landowner will be incorporated into the planting plans whenever
possible.
The riparian restoration component of this project was broken down into a three-
zone approach. The species selected were chosen to be aesthetically pleasing and to
benefit wildlife by providing food or habitat. We are also supporters of the Southern
Appalachian Native Plant Initiative (SANPI), so we will only be using native species to
revegetate the riparian zone. A selection of the following species will be used at this site:
Arrowhead (Sagittaria latifolia), Pickerelweed (Pontederia cordata), Cardinal Flower
(Lobelia cardinalis), Henry's Garnett (Itea virginica), Dog Hobble (Leucothoe
fonianesiana), Bushy St. Johnswort (Hypericum densiflorum), Buttonbush (Cephalanthus
occidentalis), Silky Dogwood (Cornus amomum), Baldcypress (Taxodium distchum),
Black Walnut (Juglans nigra), Green Ash (Fraxinus pennsylvanica), Red Maple (Acer
rubrum), and Sycamore (Platamus occidentalis). All flower species will be planted 3 to 4
feet apart, bush species 4-8 feet apart and trees will be planted 10-15 feet apart.
MONITORING
Stream channel morphology will be monitored based on the existing data
conditions for three-years following the restoration. Pennington and Associates will
conduct the macrobenthos monitoring. Please see Appendix-E for the Macrobenthos
Monitoring Plan by Pennington & Associates.

Introduction
Lynn Hauen It, L.LC d.b.a. Glenstone Health Care proposes to relocate 470 feet of existing stream to the
northeast property boundary and pipe 378 feet near the southern portion of their property in Watauga County.
North Carolina. The stream is a tributary to the East Fork New River. In response to an application for section.
401 certification, the State of North Carolina Department of Environment, Health and Natural Resources,
Division of Water Quality (NCDEHNR) has requested " A macrobenthos monitoring plan will be needed for the
stream. You must monitor the stream at two locations before disturbance, and at two locations for three
additional years after the stream has been moved" (letter dated July 29. 1997 by John R. Mmay). Pennington &
Associates, Inc. proposed the following plan to address the needs of the NCDEHNR.
LOCATION
As stipulated by the NCDBHNR, two sites will be selected on the Glenstone Health Care property for
monitoring prior to construction and relocation. The same sites will also be utilized for the three years after the
stream relocation. It is proposed that the control station be located at the northwest corner of the property where
the existing stream enters the property. The second location will be placed at the southeast comer of the
property, in the existing stream, below the relocated portion and where the piped section enters the existing
stream. Specific locations will be selected by Pennington & Associates, Inc. and representatives of Glenstone
Health Care during the first site visit.
DATES
'The first sampling date, or pre-stream location period, as well as the following three samplings years,
will be in early September. The September season should provide low flow and high temperature conditions in
the stream. 'These conditions are the most stressful for the aquatic fauna in the stream,

MATERMAES AND METHODS
Techniques used for the benthic macroinvertebrate survey will follow guidelines set forth in Standard
Operating Procedures, Biological Monitoring, Environmental Sciences Branch, Ecosystems Analysis Unit,
Biological Assessment Group, North Carolina Department of Environment, Health and Natural Resources,
Division of Environmental Management, Water Quality Section, January 1997 (pages 3-17).
At each of the two sites selected for the benihos survey, sampling techniques for wadable streams will
be utilized, Icirknet, sweepnet, and visual collecting techniques will be used to collect the benthic samples. At
each location, two kick samples (>1 ms each), net sweeps ( a minimum of three composite samples), leafpack and
debris collections (one composite sample), epifaunal collections (two composite sample minimum), and visual
collections froin maerophytes, logs, boulders, etc, and a sand sample will be collected. All samples will be
screened in the field with a 200 micron mesh net and field picked (enumerations limited to Rare (1-2 organisms),
Common (3-9 organisms); and Abundant, (>10 organisms). The remaining samples will be placed in plastic
containers, labeled on the inside and outside of the container, preserved in 10% formalin and transported to the
Cookeville, Tennessee laboratory for additional processing.
Physical characteristics to be determined at each site include substrate Composition (Wentworth Scale),
width, depth, velocity, flow and immediate watershed utilization. Habitat assessment will be determined using
DEHNR's Habitat Assessment Field Data Sheets (Mountain/Piedmont Streams).
Water quality parameters to be measured at each site include temperature, dissolved oxygen. pH and
conductivity, Visual determinations of turbidity will also be recorded.
In the laboratory, the samples are cataloged by assigning a Pennington & Associates, Inc. (PAI)
identification number. After cataloging, the samples are rinsed through it 200 micron mesh screen and the
remaining organisms removed from the detritus under SX magnification. If the sample contains an abundanoe of
organisms (>250), it will be processed by first "picking" through the sample, removing any large organisms such

as mussels, snails, megalopteraos, odonates and representatives of EPT taxa (Ephemeroptera, Trichoptera and
Plecoptera) that were missed during the field pick. This portion of the sample is referred to as a prepick and is
processed with the field pick. After the sample has been prepicked, the remaining sample is split using a
modified Water's Sample Splitter which splits the sample into 10 subsamples. Subsamples are randomly selected
and processed completely until a minimum of 250 individuals have been removed. This allows the investigators
to calculate the total number of individuals per sample. The organisms are transferred to 85% ethanol after
removal from the debris. The individuals will be identified to the lowest practical taxonomic level (species level
in most cases) using available keys and counted. Identifications will be made with a steriomicroscope (7X to
60X). Slide mounts will be made of the chironomids, simubids, oligochaetes and small crustaceans, and
identifications made with a compound microscope. The chironomids, simuliids, and oligochaetes are to be
cleared for 24 hours in cold 10% KOH. Temporary mounts are made in glycerine and the animals returned to
80% ethanol after identification. When permanent mounts were desired, the organisms will be transferred to 959o'
ethanol for 30 minutes and mounted in euperol. Aii species will be retained in individual vials in 85% ethanol
(or on glass slides if mounted) labeled by PAI number and pertinent project information and archived for a
minimum of 5 years.
The benthic data will be analyzed using DEHNR's recommended measures including total taxa richness,
EFT taxa richness, and biotic index (using DEHNR's assigned tolerance values). Additional community measures
which will be used to analyze the data include: diversity, evenness, percent similarity, jac card coefficient,
community loss index, percent contribution dominant taxa, ratio of Scraper and Filtering Collector Functional
group, ratio of Shredder Functional group and total number of individuals, and EPT taxa and Chironomidae
abundance ratio.

A. Mow the side slopes, not including normally submerged vegetated shelf, according to the season. Maximum grass
height will be 60%
B. Cattails, and other indigenous wetland plants, are encouraged along the pond perimeter; however, they must be
removed when they cover the entire surface area of the pond.
C. The orifice is designed to draw down the pond in 2-5 days. If drawdown is not accomplished in that time, the
system ma A be clogged. The source of the clogging must be found and eliminated.
D. All coma obents of the detention pond system must be kept in good working order.

Dear Mr St. John:
Please reply to Florida Address

-:N v
C

Enclosed you will find the respond to your letter dated July 21, 1998 regarding the aforementioned project. I
am sorry the respond was not'-'completed and returned to you earlier but the project was placed on hold
pending some ecisions regarding the proposed project. We are now back on active status and have
completed the requested modifications or clarifications.
The required items checklist for the Extended Dry Detention Basin Worksheet is enclosed.
1. Additional Treatment
The additional treatment as referred in your letter has been met. The 85% TSS removal is a accomplished
by the filter area as shown on the plans and the details. The volume of filtration area and the material to
be used are shown on the detail. The method of filtration as shown on the `plans will provide 85% TSS
removal.
2. Outlet Device
The outlet device for the temporary pool captures the runoff from a 1 year , 24 hour storm and releases it
over a 48 hour period. The calculations to show that it meets these requirements is shown on the details
sheet (3 of 3).
3. Drain
A three and on half (3.5) inch orifice has been added to the plans to provide a method to completely drain
the basin.
Page 2: Lynn Haven H, DWQ 970412/February 8,1999
4. Access
Access to the inlet side of the basin is provided from the Northern property line. Access to the
embankment side of the basin is provide from the employee access area around the building and to the
basin crossings over the proposed ditch will be utilized if necessary.
5. Sediment Storage
The design of the basin provides more detention volume than is required by treatment and the twenty five
year storm. The detail on sheet 3 of 3 shows the 20% detention volume and its respective elevation within
the basin.
6. Sediment Removal
The basin is not intended to be used as a sediment basin during construction, but if it become necessary
the accumulated sediment will be remove prior to implementation as part of the Stormwater Management
System.
7. Vegetation plan
Sheet 3 of 3 shows the vegetation plan for this basin and provides a schedule for stabilization of the
embankments with 14 days of construction and provides the type of grasses to be utilized with the
construction and completion.
8. Operation and Maintenance Agreement
The operation and maintenance agreement is attached and signed by the responsible party and notarized.
Please review the enclosed plans and information and approve. Thank you for your consideration and if you
have any questions, please do not hesitate to call.

Dear Mr. Ramsey:
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. Permanent Water Quality Pool, Draw Down Orifice Outlet
An extended wet detention basin must not include outlet structures that allow the permanent pool to
draw down. Please see page 12 of the NCDENR Stormwater Best Management Practices Manual,
November 1995, for a figure that depicts how the outlet structure should be designed to maintain the
permanent pool. The outlet structure that you have proposed includes a riser that is perforated at its
base as well as a draw down orifice located at the bottom elevation of the pond. The riser should not
be perforated at the base and the invert of the draw down orifice should be designed such that draw
down will cease when the water surface is at the permanent pool level. Also note that pages 1 and 2
of the plans show the emergency spillway to be 1 foot in elevation above the top of the embankment.
2.--- Forebay -
All stormwater wet detention basins are required to have a forebay to facilitate TSS removal. The
forebay should be approximately 20% of the total basin volume. (Note the top of the embankment
that separates the forebay from the main pond can be submerged.) Reference NCDENR Stormwater
Best Management Practices Manual, November 1995, page 4, item Le. Please revise the
engineering plans to meet this requirement.
3. Emergency Drain
An emergency drain must be provided to draw down the permanent pool volume. Reference
NCDENR Stormwater Best Management Practices Manual, November 1995, page 4, item 3.d.
Please specify this on the engineering plans and supply calculations.
4. Access
Access to the pond must be adequate to allow for maintenance of the basin and associated structures.
Please specify access routes on the engineering plans.

Subject: Lynn Haven II, LLC
DWQ Project No. 970412
Watauga County
This Office is receipt of a revised stormwater management plan for the subject project submitted on your
behalf by R&S Engineering and Construction Company. R&S Engineering has proposed constructing a
gravel/sand filter type device which is not described in the NCDENR Stormwater Best Management
Practices Manual. The Manual does describe sand filter and infiltration type devices, but our experience is
that these devices tend to fail and require rigorous maintenance in Mountain and Piedmont settings. As
such, these type devices are typically approved for coastal counties, only. Also, in order to obtain approval
for devices not included in the NCDENR Stormwater Best Management Practices Manual, it is the
Division's policy to require a Preliminary Evaluation Procedure (PEP). As part of the PEP, the applicant
must provide documentation for the effectiveness of the device, and must provide long-term monitoring
(including influent and effluent sampling) to establish the effectiveness of the device. If the device is shown
not to perform adequately, the applicant must provide additional treatment until adequate treatment is
achieved. As such, this Office recommends that you consider constructing a wet detention pond or an
extended wet detention wetland as described in pages 2 -15 and pages 20 and 21 in the NCDENR
Stormwater Best Management Practices Manual. Based on the submitted dry detention pond design
submitted by the engineer, it appears that there may be adequate space to accommodate such designs.
These issues were stated in brief in our previous correspondence. Also, there seemed to be an apparent
misunderstanding regarding extended dry detention and wet detention as defined in the NCDENR
Stormwater Best Management Practices Manual, November 1995. This Office would like to expedite the
stormwater management plan approval process. As such, I recommend we establish a meeting to clarify our
stormwater requirements and resolve the remaining issues regarding the stormwater management plan.
If you have any questions or would like to discuss this project, please contact me or Mr. Todd St. John at
[phone].

Dear Mr St. John:
Please reply to Florida Address
I am in receipt of your letter dated February 19, 1999 requesting additional information and clarification
regarding the aforementioned project.
1. Additional Treatment. The proposed retention area is designed as a wet retention area as outlined in the
NCDENR Stormwater Best Management Practices Manual, November 1995. The wet retention area has
the volume to store and treat the 1-inch storm and release over forty eight (48) hours. The sediment
forebay is large enough to filter the water to remove 85% of the TSS. The wet retention area has a
twenty (20) percent additional volume as requested previously. The wet retention area as designed meets
the intent of the NCDENR Stormwater Best Management Practices Manual as well as the Federal
Guidelines outlined in Urban Drainage Design Manual Hydraulic Engineering Circular No. 22
dated November 1996. Chapter 10 of the Federal Manual is dedicated to Urban Water Quality Practices.
2. Drainage Area. The wet retention area is designed to treat all of the runoff to the basin. The parking
area and the building provides the runoff to the basin. The drainage area for water quality is shown on
Sheet 2 of 3 and comprises 2.81 acres.
3. Operation and Maintenance Agreement. The Operation and Maintenance Agreement that was
provided with the previous submittal is for a Wet Retention Basin. The Wet Retention Basin as designed
meets the water quality and volume requirements of the NCDENR. I included as a supplement additional
inspection and clean criteria for this type of Wet Retention Basin.
Please review and approve and thank you for your cooperation.
Sincerely,
David F Ramsey, P E, PSM

SITE SPECIFIC OPERATION AND MAINTENANCE PLAN
MAINTENANCE:
1. INSPECTION. The Stormwater Management system shall be
inspected several times in the first few months of operation,
and twice annually thereafter. Additional inspections shall
be conducted after large storms to check for surface
ponding that might indicate local or widespread clogging.
Inspections should include but not limited to outlet clogging,
erosion on embankments, erosion at inlet and outlets, sediment
accumulations/removal, condition of emergency spillway and
woody vegetation in the embankment.
2. BUFFER MAINTENANCE. The conditions of the grass filter
areas shall be inspected twice annually. Growth should be
vigorous and dense. Bare spots, eroded area, or burned
out area should be reseeded or resodded.
3. MOWING. Grass areas are to be mowed at least twice a
year to prevent woody growth and provide aesthetics. Filter
area performance will be impaired if the grass is cut too
short. To prevent grass clippings from clogging the area,
mowers should be equipped with baggers or at a minimum be
directed area from the filter area.
4. SEDIMENT REMOVAL. The pre-treatment inlets to filter areas
should be checked periodically and cleaned out when sediment
fill more than 10 percent of the original capacity. The cleaning
of these are °? be by manually or by a vacuum pump. Inlet
and outlepiould be checked for clogging and vandalism.
5. TREE `RUNING,_=Adjacent trees shall be trimmed if their drip
line extend'b er a surface or filter area so that tree leaves
do not clog the filter areas. Any pioneer trees hat start to
grow in the vicinity of the filter area will be removed immediately
thereby avoiding root puncte°f --the filter area through which
sediment might enter the stru.cture-.--
6. RESPONSIBLE PARTY. The responsible party for the operation
and maintenance plan is Sara Massey, Financial Manager

The extended wet detention basin has been modified to permit permanent pool discharge by a valve
for emergency drainage only. The valve can be control from the top of the riser. The perforations
were depicted at the wrong location on the detail on sheet 3. The perforations do not extend blow the
permanent pool top elevation. The perforations are designed for 2-5 day draw down of the 1" of
treatment volume. There will be not draw down below the permanent pool elevation. The note on
pages 1 and 2 regarding the emergency spillway and top of embankment has been corrected.
2. Forebay
The Forebay has been added to the drawing depicting 20% of the basin treatment volume.
3. Emergency Drain
The emergency drain has been correct to drain with a valve system as explain in item 1 above.
4. Access
The access to the wet detention area has been shown on the plans.

Dear Mr. Ramsey:
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. Please find the attached
Extended Dry Detention Basin Worksheet. In the worksheet, Part II, Required Items Checklist lists the basic
requirements for an extended dry detention basin designed to meet Water Quality requirements specified in
15 A NCAC 2H .1008. The following items, in particular, should be addressed:
1. Additional Treatment
15 A NCAC 2H .1008 (h) Alternative Design Criteria specifies that the stormwater management
system shall provide 85% average annual TSS (Total Suspended Solids) removal. The TSS removal
for Extended Dry Detention is assumed to be 50%. As a result, additional treatment will be required
to meet the 85% TSS removal requirement. Additional treatment measures and their respective
assumed removal efficiencies are specified in Stormwater Best Management Practices in North
Carolina, (Manual) November 1985, page 1, Introduction. Please revise the stormwater management
system plan (and include any necessary calculations) to provide 85% assumed TSS removal
efficiency.
2. Outlet Device
The outlet device for this temporary pool shall either capture runoff from 1 yr., 24 hour storm and
release it over a 48 hour period, or capture runoff from 1 inch storm and draw down over a period of
2 to 5 days. Please provide the calculations to show that this requirement has been met. Reference
Stormwater Best Management Practices in North Carolina, (Manual) November 1985, page 74.
Drain
A drain must be provided to completely empty the basin for cleanout. Reference Stormwater Best
Management Practices in North Carolina, (Manual) November 1985, page 74.

4. Access
Access to the pond must be adequate to allow for maintenance of the basin and associated structures.
Please specify access routes on the engineering plans. Reference Stormwater Best Management
Practices in North Carolina, (Manual) November 1985, page 74.
5. Sediment Storage
The design must provide for sediment storage in addition to the detention volume. The amount of
storage must be 20% of the detention volume. Reference Stormwater Best Management Practices in
North Carolina, (Manual) November 1985, page 74.
6. Sediment Removal
If the basin will be used as a sediment basin during construction, the plans must clearly indicate that
accumulated sediment will be removed prior to implementation as a wet detention basin. Reference
NCDENR Administrative Code Section 15A NCAC 2H .1000 Stormwater Management, December
1995, Section .1008, item c.7
7. Vegetation Plan
A vegetation plan prepared by a North Carolina licensed professional is required. Consideration
must be given to the grasses specified because of frequent inundations. Also, the plan should specify
that the basin will be stabilized within 14 days of construction. Reference Stormwater Best
Management Practices in North Carolina, (Manual) November 1985, page 74.
8. Operation and Maintenance Agreement
An operation and maintenance agreement is required. Reference NCDENR Administrative Code
Section 15A NCAC 2H .1000 Stormwater Management, December 1995, Section .1008, item i.
The operation and maintenance agreement must also be signed by the responsible party and
notarized.
The requested information or a deadline extension request must be submitted within 30 days.
Division wetlands unit staff will strive to complete a final technical review within 10 working days of
receipt of the requested information. Completing the enclosed worksheet will greatly decrease the staff
review time. If you have any questions or would like to discuss this project, please contact me at (704)

Dear Mr Dorney:
Enclosed you will find the revised Drainage Plan for the aforementioned project. We have placed the
retention area at the location as discussed by telephone in October.
The storm drainage entering the property from the south has been routed through the new storm drainage
pipe under the proposed building. The storm drainage pipe under the building will carry the 99.8 cfs that
would be created by a 100 year storm and the low area between the building and the roadway will provide for
additional ponding if the 100 year storm is exceeded.
The drainage from the new parking area is directed to the new retention area with a ten year storm criteria as
requested by the Village of Boone and the first one inch of runoff as required by Division of Water Quality. A
cross section of the retention is shown on the plans and provides for a draw down of approximately 2 to 5
days. The retention area is designed as an Extended Drv Detention B sins and meets the design criteria as
established by the Division of Water Quality. The retention area will contain a total of 20,202 cubic feet of
water in which water quality for the first one inch is 10,662 cubic feet and the additional retention of the ten
year storm event as required by the Village of Boone is 8,010 cubic feet.
The specifications for the construction of the retention basin is shown on the plan along with all of the
drainage calculations for sizing the retention basin. The drainage pipe sizing criteria is shown on the plans for
each pipe along with the discharge elevations for the Riser Pipe.
Please review and approve at your earliest possible convenience and if you have any additional questions or
concerns, please do not hesitate to call.
Sincerely,
David F Ramsey, P E

the 401 Certification is issued.
III. Stormwater: You will need to design a permanent, wet detention stormwater pond or
ponds to treat runoff from the entire site. As I discussed with Mr. Ramsey, your plan to utilize
the existing "wetland/seep" area for stormwater treatment is unacceptable since these wetlands
will be degraded during the treatment of this runoff. You may choose to design the facility to
discharge into the wetland/seep complex after treatment for polishing the runoff and/or if you are
not able to achieve the 85% TSS treatment goal We will need to receive the stormwater
management plan before the 401 Certification can be issued.
Please call me at 919-733-1786 if you have any questions.

DATE: July 11, 1997
SUBJECT: U.S. Army Corps of Engineers Public Notice No. 199702715, Review of a permit
application submitted by Glenstone Health Care to relocate and culvert 846 linear
feet of unnamed tributaries to the East Fork New River in conjunction with the
construction of Lynnhaven II, Watauga County
The North Carolina Wildlife Resources Commission has reviewed the information
provided by the U.S. Army Corps of Engineers, and biological field staff conducted a site visit
on 6 January 1997. 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 applicant plans to construct a h alth cti.re facil tv at th!? intersection of SR 1.524 and
SR 1656 near Boone. As part of the project, the applicant proposes to relocate 468 linear feet of
an unnamed tributary on the west side of the property around the building site. The new channel
will be designed to mimic the old channel in terms of substrate, bankfull width, meander pattern,
gradient, and riparian zone. The new channel will be approximately 576 linear feet. On the east
side of the property, approximately 378 linear feet of two other unnamed tributaries will be
routed through a culvert around the far east side of the property. Work in wetlands at the project
site will be avoided, and they will be protected from future development. In addition, the
applicant is currently trying to purchase the land or pursue a conservation easement for the
stream channel downstream of the property line to Bamboo Road. If successful, the applicant
plans to stabilize eroding banks and plant native woody vegetation to provide bank stability and
shade to the stream. If the applicant is unable to acquire the land or an easement, he will make a
contribution to the Environmental Trust Fund for mitigation.

The East Fork New River supports wild trout, and the tributary that will be relocated
likely serves as a trout nursery stream. We have previously met with the applicant and provided
him with information regarding stream relocation using bioengineering methods.
We have no objection to the issuance of this permit, provided the following conditions
are met:
1) The new channel should have the same average depth, width, and meander pattern as the
existing channel. Following our preliminary comments, the applicant has classified the
stream and does plan to mimic existing conditions as much as possible. We appreciate
the detailed plans that were included with the 404 permit application.
2) The new channel should be constructed "in the dry" and be completely stabilized before
water is turned into it.
3) The use of riprap should be avoided for bank stabilization. We are pleased that the
applicant plans to use coir logs rather than riprap to stabilize the toe of the bank.
4) Temporary or permanent herbaceous vegetation should be planted on all bare soil within
15 days of project completion to provide long-term erosion control. If seeding is not
feasible because of adverse weather conditions, mulch should be placed on all bare soil.
5) Native species of trees and shrubs should be planted along the new stream channel to
provide shade, additional bank stability, and a travel corridor for wildlife. We are pleased
that the applicant has already selected various native species to plant along the new
stream section.
Thank you for the opportunity to review and comment on this project. If you have any
questions regarding these comments, please contact me at 704/652-4257.

Re: Proposed fill of waters and wetlands
Watauga County
WQC Project #970412
On 8 May 1997 the Division of Water Quality (DWQ) was notified by receipt of your
application regarding your plan to fill wetlands and waters for the purpose of constructing a
health care facility in Watauga County. Approval from DWQ is required to disturb these
wetlands. We understand that the U.S. Army Corps of Engineers will make this project an
Individual Permit with an accompanying Public Notice. Until we are supplied the
following information, this project is incomplete and will remain on hold:
1. a design for the relocated streams and their buffers,
2. a stormwater management plan with permanent, wet detention ponds to control
runoff from the site, and
3. an off-site mitigation plan if the net stream culverting is equal to or greater than
150 feet.
Until this information is received, this application is incomplete and our processing
time will not start.
Please call me at 919-733-1786 if you have any questions or would require copies of
our rules or procedural materials.
Sincerely,
John R. orney
