EXECUTIVE SUMMARY
For this project, the goal and objective is to restore physical and biological integrity beyond current
stream conditions. Current conditions consist of channelized, modified and impaired stream reaches,
exacerbated by nutrient loading from agricultural land use and streambank denuding, destabilization
and erosion from cattle intrusion. Restoration of the streams, utilizing methodical and varying
mitigation approaches, will provide the desired habitat and stability features necessary to improve
the quality of the streams. Objectives to meet these goals are listed below.
• Provide stable stream channels with features characteristic of a biologically diverse
environment
• Restore the connection between the bankfull width and floodprone width of the channels by
improving the floodplain area
• Stabilize eroding streambanks
• Provide functional, native riparian corridors where deficient, and preserve existing forested
corridors
• Improve physical aquatic habitat features
• Minimize land development impacts to the streams
• Provide long-term protection of the stream corridors via perpetual conservation easements
The restoration measures proposed for Davis Branch mainstem and Unnamed Tributary 1 (UTI)
will provide the attributes described above by incorporating mitigation approaches to the levels
required to support stability and biological diversity essential to ecosystem enhancement.
Presently, these features are absent or diminished within the project stream reaches and corridors.
The restoration of the Davis Branch mainstem and UTl includes assessing and quantifying stable
geomorphologic reference reach conditions that is the foundation for the design and construction
of stable natural channels. Considerations that have been applied to the design of this project are
listed below.
• Channels designed with appropriate bankfull dimensions, cross-sectional areas and profile
gradients to convey predicted bankfull flows and entrain bedload readily available to the
streams, without aggrading or degrading.
• Channel pattern, profile and dimension extrapolated from data collected at a stable
reference reach within the same watershed, physiographic province, ecoregion, geologic
setting and valley type as the Davis Branch project reaches.
• Grade control and bank stabilization structures to enhance environmental and ecological
attributes of the stream channels through the use of natural materials and indigenous,
native revetment.
• In-stream aquatic habitat features, such as riffle-run-pool-glide complexes, and re-
establishment of instream, overbank and riparian zone vegetation will provide shade and
streambank stability.
• In-stream structures, such as cross-vanes, bank stabilization enhancements, or
combinations thereof, constructed using native rock and log structures will be utilized
where needed to alleviate near-bank shear stress, provide grade control, stabilize
streambanks and create aquatic habitat.
• Reconnection of the stream channels to functional floodplains by making improvements to
the stream channels, floodprone areas and riparian zones that restores dimension, pattern
and profile based on reference reach conditions.

• • Establishment of indigenous instream, overbank and riparian herbaceous ground cover,
shrub, understory and canopy species throughout the project riparian corridors, where
deficient. Existing vegetation present along the streams will be preserved to the maximum
extent practicable.
Proven natural geometry relationships, as described by Newbury, Leopold, Wolman, Miller, Rosgen
and others, provide the basis for designing stable, self-maintaining stream channels. Empirical and
quantitative relationships between drainage area, discharge, channel pattern, profile and dimension
form the foundation for restoring the physical and biological functions of streams. Stream mitigation
approaches including preservation, enhancement, and full-scale restoration has been thoroughly
evaluated for each project reach, as defined in the multi-agency April 2003 Stream Mitigation
Guidelines. Mitigation approaches were evaluated in terms of meeting stated project goals and
objectives. Due to historical stream modifications (channelization) and existing agricultural land use
impacts (nutrient laden runoff and livestock encroachment), restoring dimension and profile only
will not achieve the required level of ecological enhancement needed to return the each of the
impaired project reaches to stable, natural conditions.
To achieve the most beneficial outcome, from an ecosystem enhancement perspective, a combination
of Preservation, Level I Enhancement and Priority Level 1/II restoration is proposed on Davis Branch
mainstem. A combination of Enhancement Level II and Priority Level I restoration is proposed for
Davis Branch UT1. On the mainstem reach, approximately 766 linear feet (11.) will be preserved,
1,802 11 will be restored utilizing a Priority Level I/II approach, and 1,229 l.f. will be restored
utilizing an Enhancement Level I approach. Approximately 396 l.f. of stream will be restored on
UT1, utilizing an Enhancement Level II approach. The final 450 l.f. on UT-1 will be restored
• utilizing a Priority Level I restoration approach. The sum of the proposed total restored stream
lengths designated in this restoration plan is approximately 4,718 l.f. Pre-existing and proposed
stream lengths and restoration approach are summarized in the following table, including proposed

2.2 Surface Water Classification/ Water Quality
is As noted in Section 1.2, the Davis Branch watershed is located within the USGS 14-digit
HUC Watershed 030401050-70080. Davis Branch and UT1 are first and second order
headwater tributaries to Gourdvine Creek of Richardson Creek of the Rocky River in the
Lower Yadkin-Pee Dee River Subbasin 03-07-14. Subbasin 03-07-14 includes a portion of
the Rocky River including the Richardson Creek and Lanes Creek Watersheds. The Rocky
River cuts across the northeast corner of this subbasin from the confluence of Long Creek
(Subbasin 03-07-13) to the Pee Dee River. Richardson Creek and Lanes Creek flow in a
northeasterly direction into this lowest segment of the Rocky River catchment. Most of the
subbasin lies in Union County. Major municipalities include Unionville and Monroe to the
west and southwest, respectively. Smaller municipalities include Marshville and Wingate,
North Carolina, to the south and south-southwest, respectively.
The Yadkin-Pee Dee River Basin Watershed Restoration Plan (December 2003) notes water
quality cannot be generalized across the 420 square mile Rocky River, Richardson Creek and
Lanes Creek Watersheds. Based on DWQ monitoring between 1998 and 2001, there are no
High Quality or Outstanding Resource Waters in this subbasin. While the Davis Branch
restoration project is not located within a targeted WRP watershed in the subbasin, it is a
headwater tributary in the Richardson Creek catchment impaired, in large part, by non-point
source nutrient and sediment loading from agricultural runoff. Richardson Creek is impaired
due to low dissolved oxygen concentrations, excess nutrients and sedimentation. Water
chemistry data show extremely high nutrient levels, with high nitrate/nitrite and total
phosphorus concentrations. Portions of Richardson Creek are currently listed on the state's
• draft 303(d) list as of December 2003.

• Restoring the project streams and their riparian corridors will help improve instream water
quality in the Richardson Creek catchment. This will be accomplished by reducing the
volume of erosion of nutrient enriched soils from vertical to undercut, incised streambanks,
excluding livestock from the riparian corridors, providing sediment and nutrient storage
along the revegetated floodplain areas and riparian corridors, where deficient. and by
protecting the restored stream corridors via the recorded, perpetual, 150-feet wide, 13.12 acre
conservation easement granted to the State of North Carolina on August 24, 2007, at Deed
Book 4666, Page 306 and Deed Book 4666, Page 315, and shown on a Plat of survey at Book

Richardson Creek and Lanes Creek, respectively. Three USGS 14-digit HUC WRP Targeted
Watersheds (03040105-081010, -081020, and -081030) in the adjacent Lanes Creek
watershed, southeast from the Davis Branch and Unnamed Tributary project site, have been
prioritized as areas with the need and opportunity for stream and wetland restoration efforts
by the NC DWQ and NC EEP. The map is from Section B, Chapter 14 of the Yadkin-Pee

EEP Contract # D06054-F
• Davis Branch, typical of many of the headwater streams in the Richardson Creek and Lanes
Creek catchments, is primarily agricultural land with dug-out impoundments or dammed
headwater tributaries used as farm ponds to water livestock. The cited December 2003 basin-
wide restoration plan. addressing surface water quality issues in the Richardson and Lanes
Creek watersheds, recommends the following actions be taken to improve instream water
quality: Reduce nutrients from all sources (agriculture, wastewater infrastructure, and
stormwater runoft); widespread implementation of BMPs to control nonpoint sources of
pollution, particularly from agricultural activities, throughout the watersheds, and no new
discharges of oxygen consuming wastes be permitted on Richardson Creek above the Monroe
WWTP. The following photograph, taken at the bottom of the Davis Branch mainstem
project reach on March 9, 2006, graphically shows nutrient laden agricultural runoff
exacerbated by livestock intrusion, and hoof-shear streambank destabilization leading to
erosion and offsite discharge of oxygen consuming agricultural runoff and sedimentation.

The preceding photographs shows the impacts of nutrient enriched runoff and sedimentation
from agricultural lands, typical in the Rocky River, Richardson Creek and Lanes Creek
Watersheds. Restoration and protection of headwater streams and their riparian corridors,
such as proposed in this restoration plan for Davis Branch and UT1, throughout Subbasin 03-
07-14 will have a cumulative, positive impact on improving instream water quality, riparian
and aquatic habitat.
2.3 Physiography, Geology, and Soils
Physiography
The Davis Branch watershed is located in the Piedmont Physiographic Province of south
central North Carolina in the Carolina Slate Belt Ecoregion (Draft Level III and Level IV
Ecoregions of North Carolina, USEPA, USDA-NRCS & NCDENR, August 17, 2000).
Valley Type VIII (Rosgen, 1996) is most readily identified landform along the lower 2,100
l.f. reach on the mainstem corridor, with subtle terraces positioned laterally along the broad
valley (site specific floodprone width varies from 120 to 150 feet) with moderate, down-
valley elevation relief Alluvial terraces and floodplains are the predominant depositional
• features in this fluvial geomorphologic system and produce a high sediment supply as the
landform evolves. On UT1 and the upstream east-west trending reach on the mainstem, the
•

valley narrows and transitions to a moderately steep, gentle sloping side slopes Type II
colluvial valley. As shown on Figure 2 and Figure 3 the first and second order Davis
Branch stream reaches are headwater streams to Richardson Creek. Existing valley slopes for
the project reaches range from 0.0170 ft/ft to 0.0249 ft/ft with elevations from the upstream
watershed boundary to the mouth of Davis Branch ranging from 526 feet to 390 feet (NAVD
88), with a total watershed elevation relief of 136 feet.
Geology
In the project vicinity, bedrock consists of heated and deformed (metamorphosed)
sedimentary and volcanic rock. Bedrock is exposed and outcrops in the streambeds along the
mainstem and the lower segment of UT1 where the channels have incised to bedrock.
Exposed bedrock is dense, crystalline on a microscopic scale (i.e., grains not visible to the
naked eye), slate. The Carolina Slate Belt was the site of a series of oceanic volcanic islands
about 550 - 650 million years ago (Pre-Cambrian and Cambrian Systems). Metamorphic
rocks that occur in this region include meta-mudstone and meta-argillite (slate), thin to thick
bedded, bedding planes and axial-planar cleavage common; interbedded with meta-
sandstone, meta-conglomerate and meta-volcanic rock. The project site geology map is
presented on Figure 4 (general bedrock descriptions and mapped extent are from the
Geologic Map of North Carolina, NCGS, 1985).
The site is located on the northwest limb of the northeast-southwest trending Troy
• Anticlinorium. The axial plane strikes N49°E (i.e., fold crest orientation), with a regional
bedding plane dip angle of 37° to the northwest. Across the fold axis to the southeast, the
regional bedding plane dip angle is somewhat less steep, 29° to the southeast. The Troy
Anticlinorium represents a series of local anticlines (upward folded arches) and synclines
(downward folded troughs) that regionally form a large anticline. The local folds are open
and predominantly asymmetric, mimicking the asymmetric bedding plane geometries of the
parent fold. Axial plane cleavage (rock splitting planes essentially parallel to the axial plane
of the fold) is best developed where only argillites (i.e., slate - metamorphosed, fine-grained
mudstone and clay) are involved in the folding.
Four formations are recognized in the Union County portion of the Carolina Slate Belt - from
oldest to youngest, the Uwharrie Formation, Tillery Formation, McManus Formation and
Yadkin Formation, that together comprise over 16,500 feet of the Lower Paleozoic Section in
south-central North Carolina. The Uwharrie Formation represents a period of extensive
volcanism with the formation of crystal lithic and devitrified tuffs, a rock formed from
compacted volcanic fragments, generally smaller than four millimeters in diameter,
incorporated in a micro-crystalline groundmass. The Tillery Formation consists of thin
bedded, laminated argillite with some interbedded non-laminated argillite and sandstone.
Thick bedded, tuffaceous argillite characterizes the McManus Formation which also contains
an appreciable amount of crystal tuff and very fine-grained sandstone. The youngest unit is
the is the Yadkin Graywacke which consists of thick bedded graywacke and laminated
argillite. Quartz and igneous intrusions are found in all of the units. The age of the rocks
studied is Early Paleozoic, probably Cambrian or Ordovician.

Locally, the site is underlain by the McManus Fonnation which comprises approximately
11,600 feet, or approximately 70 percent of the Carolina Slate Belt section in Union County,
North Carolina. Bedrock is exposed and outcrops in the streambed along the mainstem and
the lower segment of UT I where the channel is incised to bedrock. The Davis Branch
reference reach, located on the north side of Olive Branch Road, exhibits strong slate bedrock
control. Bedrock exposed in the streambeds is dense, crystalline on a microscopic scale
(grains not visible to the naked eye), moderately to steeply dipping fractured, thin to medium
bedded slate. (Detailed local structure and stratigraphy from Randazzo, A.F., Petrography
and Stratigraphy of the Carolina Slate Belt, Union County, North Carolina, Ph.D. Thesis,

Soils
Figure 5 shows the boundaries of mapped soil units within the project site and vicinity. Soils
mapping and taxonomic descriptions are from the USDA NRCS, Soil Survey of Union
County, North Carolina (USDA - NRCS, January 1996). The soils along Davis Branch
mainstem and UT I have been derived from and developed over fine-grained metamorphic
rock formations (i.e., meta-mudstone and meta-argillite, geologic nomenclatures synonymous
with slate).
The predominant soil type mapped on the Davis Branch mainstem is the Cid channery silt
loam (map symbol - CmB on Figure 5), 1 to 5 percent slopes. This map unit consists mainly
of moderately deep, moderately well drained and somewhat poorly drained, nearly level and
gently sloping Cid and similar soils on flats, on ridges in the uplands, in depressions and in
headwater drainageways. Typically, the surface layer is light brownish gray channery silt
loam 4 inches thick. The subsurface layer is a pale yellow channery silt loam 5 inches thick.
The subsoil is 18 inches thick. In the upper part, it is light olive brown silty clay that has light
brownish gray mottles. In the lower part, it is mottled grayish brown and light olive brown
channery silty clay. Weathered, fractured slate bedrock is encountered at a depth of about 27
inches. Hard, fractured slate bedrock is encountered at a depth of about 32 inches.
Penneability is slow in the Cid soil. Average water capacity is low or moderate. The shrink-
swell potential is moderate. A seasonal high water table is perched between 1.5 to 2.5 feet
below ground surface from December through May. The depth to hard bedrock ranges from
. 20 to 40 inches. The hazard of erosion is moderate on construction sites if the ground cover is
removed. This map unit is used mainly as cropland, hay, pasture or woodland. The following
photograph shows the entire Cid pedon section, exposed to erosion along the east (river right)
bank of Davis Branch, taken on April 15, 2008, facing upstream.

Included with the Cid soils on site are areas of Badin Channery silt loam (map symbol - BaB),
2 to 8 percent slopes, mapped on river left along the mainstem Priority Level I/II restoration
reach on the Staton property and along the mainstem preservation reach on the Griffin
property.
The Badin map unit consists mainly of moderately deep, well drained undulating soils on
convex upland ridges that are highly dissected by intermittent drainageways. Individual areas
are irregular in shape and range from 5 to more than 100 acres in size.
Typically, the surface layer is brown Channery silt loam 7 inches thick. The subsoil is 21
inches thick. In the upper part, it is red silty clay. In the lower part, it is red Channery silty
clay loam that has yellow and strong brown mottles. Weathered, fractured slate bedrock is
encountered at a depth of about 28 inches. Hard, fractured slate bedrock is at a depth of about
41 inches. In some eroded areas where the upper part of the subsoil has been mixed with the
surface soil by plowing, the surface layer is reddish brown Channery silty clay loam.

Permeability is moderate in the Badin soil. Available water capacity is low or moderate. The
shrink-swell potential is moderate. The hazard of erosion is moderate in bare or unprotected
areas. Flat slate fragments on the surface helps to control erosion. The depth to weathered
bedrock ranges from 20 to 40 inches. The depth to hard, fractured slate bedrock is greater
than 40 inches. This map unit is used mainly for cropland, pasture and woodland.
An area of Badin Channery silty clay loam, 2 to 8 percent, eroded (map symbol - BdC2) is
present along the lower Enhancement Level 1 mainstem reach on Davis Branch. The soil
taxonomy is essentially identical to the BaB snap unit described in the preceding paragraph.
Some primary differences are the BdC2 map unit is poorly suited to cultivated crops because
of slope constraints and the eroded surface layer. The hazard of further erosion is very severe.
Weathered, fractured slate bedrock is encountered at a depth of about 29 inches. Hard,
fractured slate bedrock is encountered at a depth of about 41 inches. The following
photograph, taken on April 15, 2008 looking upstream on Davis Branch mainstem
Enhancement Level 1 reach, shows the erodible nature of the Badin, BdC2 soil pedon on site,
with streambank sloughing in the foreground and vertical, denuded streambanks upstream
attributed to cattle intrusion.
The GsB component of the mapped unit consists mainly of shallow and moderately deep,
well drained to excessively drained, undulating Goldston and Badin soils on ridges in the
uplands. The topography is highly dissected by intermittent drainageways. The unit is about
45 percent Goldston soil and about 40 percent Badin soil. The two soils occur as areas so
intricately mixed that mapping them separately at the selected scale in not practical.
Individual areas are irregular in shape and range from 5 to more than 100 acres in size.
Typically, the surface layer of the Goldston soil is brown very Channery silt loam 5 inches
. thick. The subsoil is light yellow brown very channery silt loam 11 inches thick. Weathered,
fractured slate bedrock is typically encountered at a depth of 27 inches. In some places
12
Goldston-Badin complex soils (snap symbols - GsB and GsC), 2 to 8 and 8 to 15 percent
slopes, respectively, are the mapped units on UT-1. GsB soils are mapped along the upper
third of the project reach. GsC soils are mapped to the confluence of UT-1 with Davis Branch
mainstem.

Penneability is moderately rapid in the Goldston soil. Available water capacity is low. The
hazard of erosion is moderate in bare or unprotected areas. Flat slate fragments on the surface
create a "mulch effect" that helps to hold water in the soil and helps to control erosion. The
depth to weathered bedrock ranges from 10 to 20 inches. The depth to hard, fractured slate
bedrock ranges from 20 to 40 inches.
The Badin soil is well drained. Typically, the surface layer is brown channery silt loam 7
inches thick. The subsoil is 21 inches thick. In the upper part, it is red silty clay. In the lower
part, it is red channery silty clay loam that has yellow and strong brown mottles. Weathered,
fractured slate bedrock is encountered at a depth of about 28 inches. Hard, fractured slate
bedrock is at a depth of about 41 inches. In some eroded areas where the upper part of the
subsoil has been mixed with the surface soil by plowing, the surface layer is reddish brown
channery silty clay loam. Permeability is moderate in the Badin soil. Available water
capacity is low or moderate. The shrink-swell potential is moderate. The hazard of erosion is
moderate in bare or unprotected areas. Flat slate fragments on the surface helps to control
erosion. The depth to weathered bedrock ranges from 20 to 40 inches. The depth to hard,
fractured slate bedrock is greater than 40 inches. This map unit is used mainly for cropland,
pasture and woodland.
• The GsB component of Goldston-Badin complex, 8 to 15 percent slopes is mapped along the
lower two-thirds of the UT-1 project reach to its confluence with Davis Branch. The GsB
snapped soil unit consists mainly of shallow and moderately deep, well drained to excessively
drained, undulating Goldston and Badin soils on hillside valley slopes, as opposed to the GsC
(2 to 8 percent slopes) soils mapped on ridges in upland areas. The topography is highly
dissected by intermittent drainageways. The unit is about 55 percent Goldston soil and about
30 percent Badin soil. The two soils occur as areas so intricately mixed that mapping them
separately at the selected scale in not practical. Individual areas are irregular in shape and
range from 4 to more than 25 acres in size.
The Goldston soil is well drained to excessively drained and is shallow over bedrock.
Typically, the surface layer of the Goldston soil is brown very channery silt loam 5 inches
thick. The subsoil is light yellow brown very channery silt loam 11 inches thick. Weathered,
fractured slate bedrock is typically encountered at a depth of 16 inches. Hard, fractured slate
bedrock is encountered at approximately 27 inches below ground surface In some places
bedrock is exposed at ground surface, resulting in narrow, scattered bands of weathered slate
outcrops. In other areas, flagstones are in and on the surface layer. Other than shallower
accumulated soil thickness attributed to hill slope landform geomorphologic processes
associated with steeper land surface slope, as described above, with the GsB component
containing a proportionately higher composition of Goldston soil based on slope position, the
GsB pedon is otherwise identical to the GsC pedon. The following photograph shows soil
conditions near the mouth of UT-1, partially obscured to vegetation on April 15, 2008,
characteristic of the on site GsB soil pedon section.

2.4 Historical Land Use and Development Trends
The land surrounding the restoration project is cattle pasture and hay land. Cattle have direct
access to the project stream reaches for drinking water, and in areas where established
riparian canopy exist, cattle access the project corridors for shade. Presently, the cattle access
the stream randomly and, in doing so, have denuded and destabilized streambanks due to
grazing, browsing and associated hoof shear. The unstable streambanks and denuded riparian
corridors are contributing large quantities of nutrient laden sediment to the project stream
reaches. Eroded sediment from the unstable streambanks is transported downstream and off
site into the larger Davis Branch, Gourdvine Creek and Richardson Creek watersheds.
Runoff from agricultural land use together with cattle intrusion along the project corridors
provides direct nutrient pathways into the project stream reaches. Currently, the upper reach
of UT1 has sparse riparian vegetation along its stream corridor. Vegetation along the existing
stream corridors is nonfunctional with respect to bank stabilization, nutrient uptake and
sediment removal from overland flow (i.e., non-point source pollutants). The approximate
lower third of UT1 and the upper Davis Branch mainstem reaches have established hardwood
forested riparian corridors. However, cattle intrusion has denuded herbaceous groundcover,
and adversely impaired shrub and mid-story canopy vegetation. Cattle intrusion is the
primary cause of stream instability on site. This photograph shows the adverse impacts of
browsing and grazing of shrub and herbaceous ground cover (vegetative denuding), hoof
shear, leading to erosion from destabilized overland sheet flow and streambanks,
• respectively.

The "Known Occurrences" column refers to the last time the species was observed in a
particular county, according to the species distribution maps from the North Carolina Natural
Heritage Program dataset. "Current" means that the species was seen in the county within
the last 20 years.
As part of the National Environmental Policy Act (NEPA) compliance procedure for the
• project, a scoping letter was submitted to the US Fish and Wildlife Service on July 11, 2006
to request information on these species and any comments with respect to endangered species
that may arise as a result of this project. This scoping letter included language specifying
that a lack of response within 30 days would be assumed to mean the USFWS had no
comments or recommendations regarding this project. No response was received within the
30 day period ending August 14, 2006.
A scoping letter was also sent to the National Oceanic and Atmospheric Administration
(NOAA)-Fisheries Service, Beaufort Field Office, on July 18, 2006 for comments on any
issues related to endangered species of essential fish habitat. During a telephone
conversation on July 31, 2006, Mr. Ron Sechler of the NOAA-Fisheries Office stated that he
had no comments related to this project.
A request for a site-specific search of the North Carolina Natural Heritage Program Database
was made to the North Carolina Department of Environmental and Natural Resources
(NCDENR). The search results returned on March 6, 2006 indicated that the database had no
record of rare species, significant natural communities, or priority natural areas at the site nor
within 1 mile of the project area.
Based on a review of available information, including a site visit, no habitat for any of
species listed in Table 3 is apparent on the site. Due to a lack of available habitat, the Davis
Branch project is not likely to have an adverse effect on any Federally-listed threatened or
endangered species. This information was presented in the Categorical Exclusion report

3.1 Channel Classification
Davis Branch Impaired Mainstem - Priority Level I/II Restoration Reach
North Carolina Division of Water Quality (DWQ) Stream Classification Form was completed
for the Davis Branch mainstem and is included in Appendix 2. The mainstem received a
score of 33.5, classifying it as a perennial channel. The stable, natural channel form for the
Davis Branch mainstem restoration reach is a Rosgen E4/1 stream type, based on a detailed
Rosgen Level III, quantitative analysis of stable reference reach conditions on August 8-9,
2006. The reference reach is located downstream from the site, beginning at the outlet end of
the culvert carrying Davis Branch under Olive Branch Road to the confluence of Davis
Branch with Gourdvine Creek. Detailed geomorphologic surveys were conducted along
representative segments of each of the impaired project reaches on July 17, 2007.
A number of anthropogenic factors have impacted the stream channel and riparian corridor
along the impaired upper mainstem restoration reach, resulting in its present unstable,
moderately incised and braided condition. Bank height ratios (BHR) calculated at impaired
pool cross-section 14+87.29 and impaired riffle cross-section 16+50.79, located 706 feet and
870 feet downstream from the mainstem preservation reach on the Griffin property, are 1.38
and 1.41, respectively (BHR = Low Bank Height/Bankfull Maximum Depth). Deep channel
• incision is attributed to uncontrolled cattle intrusion (herbaceous groundcover grazing, shrub
vegetation browsing and hoof shear) resulting in a denuded riparian landscape and
destabilized, eroding streambanks. Multiple thread channels, created by hydraulic forces that
reroute the channel around woody debris and detritus jams (channel avulsions) are present at
locations throughout the reach. (Degree of Channel Incision, River Restoration and Natural
Channel Design, Rosgen Level 4 Course Field Manual, Rosgen, D.L, 2006).

Davis Branch Enhancement Level II Reach
North Carolina Division of Water Quality (DWQ) Stream Classification Form was completed
for the Davis Branch mainstem and is included in Appendix 2. The mainstem received a
score of 33.5, classifying it as a perennial channel. The stable, natural channel form for the
Davis Branch mainstem Enhancement Level II reach is a Rosgen E3/lb stream type, based
on a detailed Rosgen Level III, quantitative analysis of a stable reference reach conditions on
August 8-9, 2006. A detailed geomorphic survey on the impaired project reach was
conducted on July 17, 2007.
A number of anthropogenic factors have impacted the stream channel and riparian corridor
along the impaired lower mainstem enhancement reach, resulting in its present unstable,
channelized, deeply incised condition. Bank height ratios were calculated at impaired riffle
cross-section 32+45.24 and impaired pool cross-section 33+49.25, located 85.3 and 187.5
feet downstream from the confluence of UT1 with the mainstem, are 1.58 and 1.86,
respectively. Deep channel incision is attributed to uncontrolled cattle intrusion (streambank
hoof shear destabilization), steep channel gradient (2.13 percent), linear channel alignment
(channel sinuosity = 1.06). The cumulative effect of these factors has resulted in nearly 5 feet
high, vertical eroding streambanks on the lower Davis Branch mainstem reach. Cross-section
photographs, facing downstream, were taken during the impaired conditions geomorphic
survey on August 17, 2007.

• With a linear channel sinuosity of 1.06, an average profile slope of 2.16 Percent, verified
bankfull discharge at 45.5 cubic feet per second, and mean bankfull velocity approaching 5.5
feet per second, the channel has incised (degraded) to bedrock. With no pattern to decrease
gradient velocity, the channel has compensated by eroding away its vertically confined
streambanks, resulting in an over-widened, over-deepened channel with unstable width/depth
relationships.
Under reference reach boundary conditions downstream on Davis Branch, where Rosgen
stream type, width/depth, pool to pool spacings, riffle lengths, riffle slopes, average profile
slope, channel dimensions and pattern relationships are within normal ranges for the Carolina
Slate Belt ecologic, geologic and physiographic region, the streambed and banks are
inherently stable. The challenging design approach to stabilize the final 1,289 linear feet of
the mainstem project reach, without the benefit of decreasing velocity gradient by adding
pattern, is presented in Section 5.0. Table 4b provides baseline morphologic and hydraulic
summaries for reference, existing and proposed channel dimension, profile and substrate,
along with additional reach parameters for lower Davis Branch. The following longitudinal
profile, created in RiverMorph v. 4.1.1, shows the Enhancement Level I impaired mainstem
project reach, with locations of impaired conditions cross-sections shown on the profile.
Following the impaired conditions longitudinal profile, the impaired conditions Rosgen
stream channel classification, dominant substrate materials readily available to the lower
mainstem reach, and geomorphologic parameters and hydraulic geometries from
representative impaired riffle cross-section 32+45.24, surveyed in the field on July 17, 2007
• utilizing differential level survey (DLS) techniques, are presented. Supporting documentation

UTI to Davis Branch
The North Carolina DWQ Stream Classification Form was completed for UTI and is
included in Appendix 2. UTI received a score of 34, classifying it as a perennial channel.
The stable, natural channel form for the Davis Branch UTI reach is a Rosgen E4/lb stream
type, based on a detailed Rosgen Level III, quantitative analysis of a stable reference reach
conditions on August 8-9, 2006 combined with a detailed geomorphic survey of the final 240
linear feet of the impaired project reach, conducted on July 17, 2007.
A number of anthropogenic factors have impacted the stream channel and riparian corridor
along the impaired UTI reach (existing conditions profile station 0+00.00 to 7+29.60)
resulting in its present channelized, deeply incised unstable condition. Bank height ratios
were calculated at impaired profile stations 5+62.69, 6+13.69 and 7+24.30 corresponding to
representative existing conditions riffle cross-section locations. Low bank heights ranged
from 1.78 to 3.45 feet, with a mean of 2.50 feet. Corresponding bank height ratios are 2.47,
3.67 and 2.32, respectively, with a mean BHR of 2.82. The extreme degree of channel
incision is attributed to uncontrolled cattle intrusion (hoof shear), steep profile gradient
(0.0230 ft/ft), linear channel alignment (sinuosity = 1.09) and high bankfull mean velocity
(6.58 ft/sec). The cumulative effects of these impacts has resulted in nearly 4 feet high,
vertical, unstable eroding streambanks on the impaired UTI reach. Impaired pool cross-
section 6+55.69 and riffle cross-section 5+62.69, located 71 and 164 feet upstream from the
confluence of UTI with Davis Branch mainstem, respectively, are presented below.
• Photographs at the line of section, facing downstream, were taken during the impaired
conditions geomorphic survey on July 17, 2007 under extreme drought conditions. The
degree of channel incision increases from the top to the bottom of the reach as shown by the
best fit trend lines through low bank elevation points plotted on the impaired conditions
longitudinal profile, presented following the impaired conditions riffle and pool cross-
sections.

Restoration Plari - Davis Branch and Unnamed Tributarl,
EEP Contract # D06054-F
• In its existing impaired state, UT I maintains E4/1b channel morphology, based on
dimensions measured at impaired reach riffle cross-sections, albeit under incised conditions.
Tables 4c and Table 4d provide baseline geomorphologic and hydraulic summary for
reference, existing and proposed channel dimension, pattern and profile, along with addition
reach parameters. The preceding screenshot from RiverMorph v. 4.1.1, shows impaired
project reach Rosgen stream channel classification, dominant substrate materials, together
with geomorphologic and hydraulic parameters for UT I.
3.2 Discharge
Bankfull discharge for the project stream reaches was quantified and verified from measured'
reference reach boundary conditions and compared to empirical relationships using data
published with the Bankfull Hydraulic Relationships for North Carolina Streams, Rural
Piedmont Regional Curve Database (Multi-Agency Stream Mitigation Guidelines, April
2003). The rural Piedmont regional curve database includes data for streams with drainage
areas ranging from 0.2 to 128 square miles. Regression equations, derived from stratified E
type stream data published in the cited document, were used to empirically evaluate hydraulic
geometry relationships at bankf ill discharge, width, mean depth, cross-sectional area and
return interval for the Davis Branch Reference Reach. The stratified regional E stream type
data Log-Pearson Type III distributions, regression equations and coefficients of
determination (R) were analyzed using the regional curve data editor algorithm in
RiverMorph v.4.1.1.
• Based on detailed quantitative analysis of reference reach boundary conditions at a stable,
bedrock controlled riffle cross-section on Davis Branch, located 43 feet upstream from the
confluence of Davis Branch with Gourdvine Creek, the stratified rural Piedmont regional
curve data very closely matches quantitatively measured and analyzed bankfull discharge and
channel geometry relationships quantified under reference reach boundary conditions.
Appendix 4 contains quantified and verified regional curve data analyses performed during
the Davis Branch Reference Reach, Rosgen Level III stream assessment. Regional curve,
reference, impaired and proposed channel discharge, dimension, pattern, profile and substrate
data are summarized in Table 4e and Table 4d.
3.3 Channel Morphology
See Section 3.1 and 3.4 for discussion of existing stream reaches channel morphology.
Tables 4a - 4d on the following pages present baseline morphologic and hydraulic
dimension, pattern and profile data for reference reach, existing and proposed conditions.
Regional curve empirical relationships comparison to reference and impaired reach
conditions is summarized in Tables 4a - 4d and discussed in greater detail in Section 3.5.
Reference reach dimensionless ratios used to size and design project reach channels are
included in Appendix 4.
In Tables 4a - 4d, where no min/max values are provided, and only one value was measured
or computed, that value is presented as the mean or median value. Where only two
• measurements were measured or computed, no mean or median value is presented.

• 3.4 Channel Stability Assessment
Davis Branch Mainstem, Impaired Restoration Reach
In its present state, the stream's high degree of channel incision (BHR range 1.38 - 1.41),
low sinuosity (K = 1.12), denuded and destabilized streambanks, relatively steep average
profile slope (0.0158 ft/ft, or 83.4 ft/mi) has resulted in a deeply incised, unstable channel
with a high sediment supply. The incised vertical to undercut streambanks, accelerate
streambank erosion. Utilizing the near bank stress bank erosion hazard index (BEHI)
algorithm in RiverMorph' v.4.1.1, it is estimated 31 cubic yards per year (or 40 tons per
year) of sediment is being eroded from the unstable, vertical to undercut streambanks along
the upper mainstem impaired reach. This estimate was calculated using the bank height (2.14
ft) measured at impaired pool cross-section 14+87.29 and the upper mainstem impaired reach
length of 1,562 linear feet and represents an estimated bank erosion rate 0.25 ft/yr. BEHI and

• Channel Stability Summary
Summing the sediment export estimates for each of the project reaches, it is estimated the
impaired streams have the potential to contribute approximately 88 cubic yards (or 114 tons)
of nutrient laden sediment off site into the larger Davis Branch, Gourdvine Creek and
Richardson Creek watersheds on an annual basis.
The consequence of channelization, cattle intrusion, confinement (lateral containment), major
floods, changes in sediment regime, and loss of riparian vegetation are attributed causes and
effects for existing conditions along the impaired project reaches. The effects of these
anthropogenic changes are accelerated streambank erosion, channel incision, land loss,
aquatic habitat loss, lowering of the water table, land productivity reduction and in-stream
and downstream sedimentation and nutrient loading.
Given the impaired condition of project reaches, the estimated annual rates of streambank
erosion are reasonable. High, sustained flows typical of heavy rainfall events associated with
stalled or slow moving tropical depressions, associated with hurricanes, come close enough
to North Carolina to influence weather about twice during an average year. Once in 10 years,
on average, hurricanes strike a part of the State with sufficient force to cause severe damage
to inland property. The average annual rainfall east of the Blue Ridge Mountains generally
ranges between 40 and 55 inches. In North Carolina the most severe weather is due to
summer thunderstorms, with July being the wettest month. These storms usually affect
is localized areas, with hail, high winds and lightning occurring with some of them, accounting
for an average yearly loss of over $5 million in property damage. At any given locality, 40 or
50 thunderstorms can be expected in a given year. (Source: State Climate Office of North
Carolina). Under prevailing regional climatic patterns, the existing conditions of impaired
site streams will continue to deteriorate and contribute significantly to offsite sedimentation
and nutrient loading without intervention.
3.5 Bankfull Verification
As noted in Section 3.2, for project stream reaches, bankfull discharge was evaluated through
quantitative analysis of stable reference reach data and calculated bankfull discharge through
a stable, bedrock controlled riffle cross-section located on Davis Branch 43 feet upstream
from its confluence with Gourdvine Creek as shown on Figure 3A and Figure 7. Discharge
versus drainage area relationships for the reference reach riffle cross-section were compared
to Bankfull Hydraulic Geometry Relationships for North Carolina Streams (Rural Piedmont)
regional curve dataset. Through this analysis, it was determined the rural Piedmont regional
curves underestimate bankfull discharge and geometric relationships for project reach
streams without stratifying the data by stream type. After recompiling the E stream type data
from the cited publication, and performing Log-Pearson Type III distribution analyses for
bankfull discharge and channel geometry relationships, the Davis Branch reference reach
quantitative data very closely matches the empirical relationships, based on stream type.
Empirical and quantified data are summarized in Table 4. The Rural Piedmont "E type
stream" regional curve data and analysis is presented in Appendix 4.
is Calculated bankfull discharge for the surveyed reference reach riffle cross-section, was
computed using hydraulic radius, wetted perimeter, channel slope and a relative roughness
(u/u*) method based on the average protrusion height of the steeply dipping bedrock bedding

• planes (Rosgen, 1998). Additionally, a particle distribution was collected from the large
angular cobble deposited along the reference reach riffle bed. Based on an average protrusion
height of 0.57 feet (or 174 mm), bankfull discharge is quantified at 77.6 cfs and very closely
matches the stratified Rural Piedmont Regional Curve dataset predicted bankfull discharge
(80.0 cfs). The D84 particle size from the stable riffle particle distribution is 140.1 mm and is
consistent with the observed bed thickness, axial splitting planes and joint sets in the folded
and deformed slate bedrock.
3.6 Vegetation
Portions of Davis Branch and UT1 exist with a mature, wooded riparian corridor dominated
by Fraxinus spp. (ash), Carya spp. (hickories), Quercus spp. (oak), Platanus occidentalis
(American sycamore), Acer saccharinum (silver maple), and Juniperus virginiana (Eastern
red cedar) in the tree canopy. Active pasturelands surround the project, and cattle have
unrestricted access to the streams. This cattle intrusion has resulted in substantial damage to
the native understory, which is essentially absent. The width of the existing riparian zone
varies along the project corridor, as is visible on the aerial photography provided on the plan
sheets in Appendix 1. In some areas, particularly the downstream portion of Davis Branch,
the riparian zone is absent and pasture grasses and Ranunculus spp. (buttercup) grow along
the stream. No potential wetlands were observed along the project corridor. Representative
photos of the existing corridor were provided in Section 2.4.

Davis Branch Reference Reach
For Davis Branch, bankfull discharge was determined through a quantitative assessment and
analysis of reference reach boundary conditions and comparison of predicted bankfull
discharge through a stable riffle cross-section located on Davis Branch 43 feet upstream from
its confluence with Gourdvine Creek. The reference reach is a Rosgen Valley Type VIII,
E3/lb stream type (i.e., E channel morphology, large cobble substrate with strong bedrock
control, profile gradient greater than 2 percent). The reference reach is located within a
healthy, deciduous hardwood forested riparian corridor. A comprehensive Rosgen Level III
watershed assessment and analysis of the reference reach conditions was conducted during
August 8 and 9, 2006. The longitudinal profile that follows, analyzed using RiverMorph"'
version 4.0.1, shows the best fit trend lines of the streambed, water surface and bankfull
indicators:

extending overbank into the channel, is extremely stable and resistant to streambank erosion.
• The streambed is stable due to hard bedrock control. Large cobble deposited on top of the
bedrock is a secondary substrate, resulting from physical weathering of the highly fractured,

EMH&T staff were able to clear line of site 151 feet deep into the overgrown Davis Branch
Reference Reach, accessing the stream from its confluence with Gourdvine Creek. Due to
backwater from Gourdvine Creek at the mouth of Davis Branch, 118 linear feet of profile,
capturing three pool and four riffle sequences, with one representative riffle and pool cross-
section being surveyed in the field. Geologic structural controls and lithology, fluvial
geomorphologic processes, depositional materials, climatic influence, riparian vegetation,
depositional patterns, debris occurrence, meander pattern, channel stability rating, sediment
supply, streambed stability and width/depth ratio state were evaluated following Rosgen
Level III stream assessment protocols. Visibility was limited in the field to dense vegetative
cover along the Davis Branch Reference Reach, therefore, Union County orthoimagery
(February 2004) was used to measure stream pattern. The high-resolution (1 pixel = 6 inches)
orthoimagery is included on Figures 3A and 7. The entire 1,129 linear feet reach was
assessed for stream state and condition parameters consistent with Rosgen Level III
assessment protocols. The assessment included spatial analysis of GPS data collected in the
field to evaluate channel pattern upstream from the surveyed reach, beyond the point where
further differential level surveying was impracticable and channel pattern could not be
discerned due to dense forested cover shown on recent aerial imagery.
The Davis Branch Reference Reach is located approximately 900 feet downstream from the
bottom of the mainstem Enhancement Level I project reach. The reference reach was studied
from the north side of Olive Branch Road to its confluence with Gourdvine Creek. The
reference reach is located on the same structural geologic feature, the Troy Anticlinorium
(northwest limb near the axial plane of an unnamed syncline), in the same geologic
formation, the McManus Formation, and is mapped on similar soils (Chewacla silt loam,

4.2 Channel Stability Assessment
Reference reach channel stability was analyzed using the vertical velocity near-bank stress
method algorithm in RiverMorph" v.4.0.1 and reach streambank observations and channel
morphology from reference reach Pool Cross-Section 1+83, located on Davis Branch 117
feet upstream from its confluence with Gourdvine Creek. The predicted annual erosion rate
estimate was calculated for the entire 1129 linear feet of stream evaluated as part of the
Rosgen Level III reference reach study. Based on reference reach conditions, the predicted
sediment loss is 3.23 cubic yards or 4.2 tons per year. This equates to 0.0043 tons/year per
foot of reach, or two one hundredths of a foot (0.02 ft) streambank erosion on an annual
basis. The near-bank adjective rating (0.35) is very low for the reference reach, indicating
extremely stable channel conditions. The quantitative inputs and analytical results from the
reference reach channel stability assessment are included with the information in Appendix
4.
4.3 Discharge
Reference reach quantified and verified discharge estimates are presented in Sections 3.2, 3.5
and 4.1. Detailed data analysis and the quantified results from that data are presented in

provides a wide riparian corridor. The canopy layer is dominated by native tree species
including: Carya spp, Platanus occidentalis, Fraxinus spp. and Carpinus caroliniana
(ironwood). The shrub/ sapling and herbaceous understory provides significant protection
against bank erosion. Native species such as Alnus serrulata (hazel alder), Cornus florida
(flowering dogwood), Sambucus canadensis (elderberry), Symplocos tinctoria (common

• 5.0 PROJECT SITE RESTORATION PLAN
5.1 Restoration Project Goals and Objectives
Restoration goals and objectives for the project are to return degraded streams to a more
natural condition that it is ecologically productive, aesthetically appealing, physically stable,
and valuable from a conservation perspective. Project restoration goals and objectives will be
achieved by restoring stable pattern, profile and dimension along the upper 1802 linear feet
(profile stations 7+81.24 to 25+83.35) on the Davis Branch mainstem and the lower 450
linear feet (profile stations 3+95.76 to 8+45.98) on UT1 restoration stream reaches, utilizing
an off-line, Priority Level I/II mitigation approach to restore the connection of the vertically
confined incised existing stream channels with their floodplains.
Channel profile and dimension will be restored on the mainstem Enhancement Level I reach
(profile stations 25+83.35 to 38+72.07) to stabilize existing over-widened and incised
channel conditions. Dimension will be restored on the upper 396 linear feet (profile stations
0+00.00 t0 3+95.76) Enhancement Level II reach on UT1, with grade control structures (rock
sills) constructed, as needed, together with placement of appropriately sized substrate
material to reduce critical shear stress in the near-bank region while maintaining flow
velocities and critical depths required to entrain medium gravel (D84 particle size = 15.4
mm), based on analysis of a particle distribution sample collected from a representative UT1
riffle streambed feature. Channel bankfull mean velocity on UT1 is moderately retarded by
• instream vegetation. Manning's coefficient for UT1 took into account observed vegetative
channel field conditions. Restoration Plan Design Sheets are located in Appendix 1.
Channel reinforcement materials will be used in high shear stress regions (i.e., along outside
meander bends). Reinforcement materials will consist of a combination of: rock toe, coir log,
coconut fiber geotextile matting held in place with hardwood stakes and soil nails; live
branch plantings; and aggressive seeding, mulching and revetment of streambanks and the
riparian corridor. Channel reinforcement methods are shown as Detail `C' on Restoration
Plan Sheet RP-13/20 and Planting Plan on RP-19 & 20/20 in Appendix 1.
The existing forested riparian corridor will be protected along the realigned Davis Branch
mainstem reach and UT1 to enhance streambank stability, provide sediment and nutrient
storage, and enhance terrestrial and aquatic habitat. Any portion of the existing corridor that
is disturbed for project-related construction will be replanted. Denuded areas within the
limits of the project conservation easement will be fully planted to reestablish a native
riparian corridor. The stream corridors will be protected by the installation of livestock
exclusion fencing placed at the edge of the conservation easement boundary. The project
planting plan is presented in Section 5.5.

5.1.2 Target Buffer Communities
The target buffer community for both riparian planting areas along Davis Branch and UT1 is
of the Piedmont/Low Mountian Alluvial Forest community type, as described in
Classification of the Natural Communities of North Carolina (Schafale and Weakley, 1990).
According to the Schafale and Weakley publication, hydrology of these areas is palustrine,
seasonally or intermittently flooded on various alluvial soils. Important characteristics
regarding the Piedmont/Low Mountain Alluvial forest Community according to Schafale and
• Weakley, 1990 include the following:
59
ECOSYSTEM ENHANCEMENT PROGRAM
Restoration Plan - Davis Branch and Unnamed Tributary 1
EEP Contract # D06054-F
• - Flood carried sediment provides nutrient input to these communities, as well as serving
as a natural disturbance factor.
- Variation is probably most related to frequency and recentness of destructive flooding.
Sites may vary due to different alluvial material and its effect on soil fertility but almost
all alluvial sites are more fertile than surrounding uplands.
- Piedmont/Low Mountain alluvial forests may be distinguished from mesic communities
by location in a floodplain and by the presence of alluvial species such as Platanus
occidentalis, Betula nigra, and Acer negundo.
- Piedmont Alluvial Forests may be distinguished from Montane Alluvial Forests by the
presence of low elevation alluvial species such as Liquidambar s raci ua, Acer
negundo, Fraxinus ennsylvanica, Ulmus americana, and Ulmus alata.
5.2 Sediment Transport Analysis
5.2.1 Methodology
The modified Shields Equation was used to calculate the largest entrainable particle size,
based on reach-specific design boundary conditions for the Davis Branch mainstem, and UT1
• (Rosgen, 1994; Williams and Rosgen, 1989; Andrews, 1984).
5.2.2 Calculations and Discussion
Shields (1936) described shear stress as:
i = 7RS
where:
T = shear stress (lbs/sq. ft.)
y = specific weight of water (62.41bs/cu. ft.)
R = hydraulic radius (ft.), and
S = channel slope (ft./ft.).
To test the relationship between shear stress and mean stream velocity at multiple flow
levels, Rosgen (1994) used an aggregate data set for six stream types. By plotting discharge
(cfs) vs. bedload (lbs/sec) it was demonstrated a significant relationship was not found for the
aggregate data set. Rosgen found, however, there is a significant empirical relationship when
the same data set was stratified by stream type and shear stress (lbs/sq. ft.) was plotted vs.
mean velocity (ft/sec) on a log-log scale.
The associated critical dimensionless shear stress (ic;*) was calculated based on the D50
particle distribution collected at impaired individual reach riffle cross-sections and composite
•
60
ECOSYSTEM ENHANCEMENT PROGRAM
Restoration Plan - Davis Branch and Unnamed Tributary I
EEP Contract # D06054-F
D50 particle distributions approximated by combining particle distributions from both riffles
and pools on each reach, respectively.
The critical dimensionless shear stress, returned from RiverMorph', is calculated using the
following equation (Williams & Rosgen, 1989):
Tc;* = 0.0834(D50BEp/D50coMP)-0872
The following equation is used to predict the depth and slope needed to move the largest size
of sediment available to the channel:
d = L?;!j(y 1350coMP)
S
Where:
ys = submerged specific weight of sediment
D50coMP = median diameter of composite sample
d = mean depth

5.3 Stormwater Best Management Practices
5.4.1 Site-Specific Stormwater Concerns
Properly installed and well maintained Best Management Practices (BMP) applications shall
adequately mitigate the impact of sediment laden stormwater flows within the project
corridors. The stormwater BMP erosion and sediment control narrative, practices, schedule,
contractor responsibilities, inspection, maintenance and soil stabilization measures are
presented on restoration plan sheets RP-15/20 through RP-18/20in Appendix 1. All BMP
applications will be inspected and maintained throughout the construction process and until
the site is stabilized per the planting plan shown on sheets RP-19/20 and RP-20/20 in
Appendix 1 and as described in Section 5.5.
5.5 Natural Plant Community Restoration
5.5.1 Plant Community Restoration Plan
The proposed riparian planting plan was developed by integrating the native plant species
observed on site, species recommended within the Guidelines for Riparian Buffer
Restoration (NCDENR - DWQ, 1/2001), as well selected species known to inhabit the
Piedmont/Low Mountain alluvial forest community type as described in Classification of the
Natural Communities of North Carolina (Schafale and Weakley, 1990) to institute species
• diversity. Table 7 presents the designed vegetative communities by zone along the streams.
Where there is no pre-existing riparian corridor, the restored stream reaches will be fully
replanted with the appropriate native species in the form of live stakes or bare-root material,
along with some larger specimens (1 gallon container size). Planting zones (Zones 1 - 4)
have been designated for the project as described in the tables on the following page. Where
a woody riparian corridor is already present along the restoration and enhancement reaches,
the existing corridor will be preserved to the maximum extent practicable and only Zone 1
and 2 plantings will be installed to provide vegetative cover immediately along the newly
restored channel. The existing riparian corridor will be maintained along the preservation
reach along the upstream portion of Davis Branch. Cattle exclusion fencing will be installed
along the boundaries of the conservation easement corridor to protect the pre-existing and
newly planted riparian vegetation. It is anticipated that the installation of cattle exclusion
fence along the stream easement corridors will allow the impaired understory to eventually
redevelop within existing wooded areas. Sheets RP-19/20 and RP-20/20 in Appendix 1
indicate the approximate extent of full riparian restoration plantings (Zones 1-4),
supplemental plantings (Zones 1-2), and preserved existing corridor.
Riparian plantings will be installed during the fall and/or spring season, as soon as possible
after the completion of the earthwork associated with the restoration and enhancement
efforts. Supplemental shrub and tree species will be planted if survival rates of previous
plantings fall below target densities. Final species selection will be based upon availability.
In addition to plantings described in Table 7, temporary and permanent seeding will occur in
Zones 2, 3 & 4. The planting plan is presented in the schematic engineering drawings,
• included on design sheets RP-20 and RP-21 in Appendix 1.

5.5.2 On-Site Invasive Species Management
This project proposes to treat and eradicate exotic woody vegetation by appropriate means.
This will help meet one of the overall goals of the restoration project by enhancing buffers
and creating habitat for birds and animals. By eradicating non-native vegetation, native
vegetation will be allowed to colonize and provide a better food source for the local fauna.
Before treatment, a vegetation assessment would be performed to determine the presence and
extent of invasive vegetation. The most appropriate treatment options will be determined
after the assessment. Invasive species that may colonize the site after construction will be

identified during post-construction monitoring events, and appropriate eradication methods
will be employed. Possible treatments for invasive exotic vegetation include application of
appropriate herbicides either through stem cut and spray or spraying of the actively
photosynthesizing leaves. This work would most likely be done in the fall or winter, during
the dormant season of most native vegetation. The initial treatment would likely take a week
to complete. Follow up and maintenance is critical in order to eradicate any root sprouts that
may occur in the following seasons.

0 6.0 PERFORMANCE CRITERIA
6.1 Streams
As discussed in the original proposal, the restoration goal for the stream is to restore the
physical and biological integrity beyond current stream conditions. Current conditions
consist of modified or impaired stream channels. Objectives to meet that goal of restoring
these stream channels are listed below:
• Provide a stable stream channel with features characteristic of a biologically diverse
environment
• Restore the connection between the bankfull width and floodprone width of the
channels by improving the floodplain area
• Stabilize eroding streambanks
• Provide a functional, native riparian corridor where deficient, and preserve existing
forested corridors
• Improve the physical aquatic habitat features
• Minimize land development impacts to the streams
• Provide long-term protection of the stream corridors, including preservation of
existing wooded corridors
Restoration will provide desired habitat and stability features necessary to improve the
quality of project streams. There are several long-term benefits associated with the
restoration of the streams, such as:
• Reversing the effects of channel incision
• Stabilizing eroding streambanks
• Development of instream habitat features
• Revegetation of the riparian corridor with native vegetation that can be utilized
by local wildlife
• Improving stream channel connection to the floodplain, providing the benefits of
sediment and nutrient storage
The restoration techniques proposed for tt
attributes described above by incorporating a
stability and biological diversity that ar,
enhancement. Presently, these features are
associated Unnamed Tributary.
e project stream reaches will provide the
variety of features recognized to support the
essential to restoration and ecosystem
diminished within Davis Branch and the
The restoration of the streams includes assessing and predicting the morphological features
that will become the foundation for the construction of a stable natural channels.
Considerations that have been applied to the design of this project are listed on the
following page.
•
66
ECOSYSTEM ENHANCEMENT PROGRAM
Restoration Plan - Davis Branch and Unnamed Tributary 1
EEP Contract # D06054-F
• • Bankfull channels designed with the appropriate dimension, pattern and profile to
convey bankfull flows and entrain bedload material readily available to the streams.
• Stable channel pattern (sinuosity) extrapolated from stable reference reach boundary
conditions.
• Grade control and bank stabilization structures to enhance the environmental and
ecological attributes of the stream channels though the use of natural materials and
native plantings.
• In-stream habitat features such as pool/riffle complexes, cross-vanes, bank
stabilization structures, and re-establishment of the appropriate substrate material.
• Improved connections between stream channels and functional floodplains.
• Installation of woody plantings where the riparian corridor is currently deficient, or
where it is disturbed for construction. Existing woody vegetation present along the
streams will be preserved to the maximum extent practicable.
Proven natural stream geometry relationships as described by Newbury, Leopold, Wolman,
Miller, Rosgen and others, is the basis for designing a stable, self-maintaining channel. The
empirical relationships between channel pattern, profile and dimension and stream flow form
the foundation for the restoration of the physical and biological functions natural streams.
6.2 Stormwater Management Devices
Properly installed and well maintained Best Management Practices (BMP) applications shall
• adequately mitigate the impact of sediment laden stormwater flows within the project
corridors. The stormwater BMP erosion and sediment control narrative, practices, schedule,
contractor responsibilities, inspection, maintenance and soil stabilization measures are
presented on restoration plan sheet RP-15/20 through RP-18/20 in Appendix 1. All BMP
applications as shown on these plan sheets will be inspected and maintained throughout the
construction process and until the site is stabilized per the planting plan shown on sheets RP-
19/20 and RP-20/20 in Appendix 1 and as described in Section 5.5.
6.3 Vegetation
The target density for the riparian buffer is to establish a minimum of 320 stems per acre
after 3 years, with a minimum of 260 stems per acre at the end of the 5-year monitoring
period within the planted areas. This would represent a minimum survival rate of 80% of the
plantings.
6.4 Monitoring Schedule and Reporting
The restoration site will be monitored for five consecutive years or until the required success
criteria have been met as determined by the EEP, NC DWQ, and USACE. As-built survey
data will be collected immediately after construction. Year 1 Monitoring activities will begin
will be conducted al least 6 months after the as-built survey. Planting will occur during the
fall of 2008 or no later than the spring of 2009; therefore, the riparian buffer restoration will
be monitored the following growing season (September 2009). Monitoring activities will
0 follow the guidelines presented in the request for proposal for this project.
67
ECOSYSTEM ENHANCEMENT PROGRAM
Restoration Plan - Davis Branch and Unnamed Tributary I
EEP Contract # D06054-F
• Parameters that will be included in the annual stream monitoring to ensure the success of the
restoration activities will include stream channel surveys (longitudinal and cross-sectional
profiles), pebble counts, photographs, and vegetation surveys. Monitoring reports will be
prepared following the EEP Monitoring Report Format, Version 1.2 dated 11/16/06.
Following the submittal of the monitoring reports to the appropriate agency representatives,
the recipients of the report will be contacted for the purpose of discussing the monitoring
data, required success criteria and whether or not the site is functioning as expected. If the
site is not functioning as expected, a site visit will be scheduled with the review agencies so
that consideration can be given to whether a remediation plan should be created and
implemented. The remediation plans, if required, will directly reflect the requested alterations
as discussed with the regulatory agencies, if it is determined that such alterations will correct
any identified deficiencies.
Stream Channels
Stream channel stability will be physically monitored by establishing permanent,
monumented cross-sections located approximately every 500 feet along the restored and
enhanced channel reaches (or no more than 2 per thousand feet). This will include four (4)
cross-sections along the Davis Branch Restoration reach and three (3) along the mainstem
Enhancement Level I reach. One (1) monumented cross-section will be surveyed along the
UTI Restoration reach and one (1) along the Enhancement II reach. Cross-sections will be
• equally distributed between riffles and pools on the project reaches. Each cross-section will
be monumented for future identification and survey. Monumented cross-sections will be
utilized as photographic points. Cross-section locations to be monitored will be established
immediately following construction during the completion of the "as-built" survey. A
longitudinal profile survey will be conducted along the entire lengths of the mainstem Davis
Branch Restoration and Enhancement 1 reaches (3,091 linear feet total), and the entire 450
linear feet of the UTI Restoration reach (noting permanent easement crossing locations).
The "as-built" mitigation plan will include the constructed stream channels dimension,
pattern, and longitudinal profile. This data will be utilized as baseline to compare future
monitoring surveys and subsequently to determine channel stability and natural adjustments
over time. Streambed particle distribution data will be collected and analyzed at monumented
cross-section bedform features. Surveyed vegetative plots will be utilized to monitor the
success of riparian plantings and vegetation conditions. Annual inspection of in-stream
structures will also occur to verify proper function and channel stability. Stream channel
monitoring surveys will be completed annually for five consecutive years, starting on Year 1
after completion of the project.
The performance standards for the restoration project are those mandated in the multi-agency
Stream Mitigation Guidelines (USACE Wilmington District, et al., April 2003).
Performance goals for the site are listed on the following page.
•
68
ECOSYSTEM ENHANCEMENT PROGRAM
Restoration Plan - Davis Branch and Unnamed Tributary I
EEP Contract # D06054-F
• • Minimal or negligible development of instream bar deposits.
• Minimal or negligible change in channel pattern, profile and dimension in comparison
to As-Built conditions. Adjustments may occur and some may be indicative of
stability, for example moderate reductions in width/depth ratios as a result of slight
channel narrowing, natural sorting and shaping of bed materials and features,
respectively.
• Maintenance of floodplain connectivity (only reductions or very small increases will
be considered acceptable).
• Target density of 320 stems per acre after 3 years and 260 stems per acre after 5 years
for planted woody vegetation (represents 80% survival after 5 years).
Subsequent monitoring reports will address the attainment of performance goals. If goals are
not be attained, then the monitoring reports will document any remedial actions taken during
the monitoring period and the success of these actions.
Riparian Buffers
Vegetation within the restored riparian buffer will be monitored for five consecutive years. A
total of 10 ten by ten meter square plots will be permanently established within planted areas
following completion of the planting phase. At least two opposing corners will be marked
and surveyed for future location in the field.
• Approximately 2.78% of the project area will be monitored following the CVS-EEP Level 1
Protocol for Recording Vegetation, Version 4.0 (Lee et al., 2006). A stem count of planted
species will be performed within each monitoring plot. The species, location, size, density,
survival rates, and cause of mortality if identifiable will be reported for each planted species
in each plot. Vegetation plots will be sampled annually and reported every year along with
the data collected during the physical monitoring of the channel. The primary focus of the
vegetative monitoring will be on the planted individuals in the tree and shrub strata.
Vegetation monitoring will occur during the month of September.
Monitoring reports and discussions of remedial actions will take place with EEP. EEP will
review the monitoring documents and make them available to the agencies after the review
period. Decision making regarding remediation will be between EEP and WRC and its agents
or representatives. Agency interaction will take place through permit requests for
maintenance should they become necessary. Agency interaction will take place at the end of
the monitoring period.

Cross-Section Monuments (Lat./Long.): 35.08722 Lat / 80.32467 Long Date: 07/17/07
Observers: M.F. Hebert, W.E. Knotts, J.M. Hines, S.T. Peffer Valley Type: VIII
inkfull WIDTH (Wbkf)
DTH of the stream channel at bankfull stage elevation, in a riffle section. 8.31
Bankfull DEPTH (dbkf)
Mean DEPTH of the stream channel cross-section, at bankfull stage elevation, in a riffle
section (dbkf = A / Wbkr). 0.91
Bankfull X-Section AREA (Abkf)
AREA of the stream channel cross-section, at bankfull stage elevation, in a riffle section.
7.56
Width/Depth Ratio (Wbkf/ dbkf)
Bankfull WIDTH divided by bankfull mean DEPTH, in a riffle section. 9.13
Maximum DEPTH (dmbkf)
Maximum depth of the bankfull channel cross-section, or distance between the bankfull
stage and Thalweg elevations, in a riffle section. 1.81
WIDTH of Flood-Prone Area (Wfpa)
Twice maximum DEPTH, or (2 x dmb1d) = the stage/elevation at which flood-prone area
WIDTH is determined in a riffle section. 124.37
ft/ft
ft
ft/ft
Entrenchment Ratio (ER)
The ratio of flood-prone area WIDTH divided by bankfull channel WIDTH (Wfpa/ Wbkf)
(riffle section). 14.97
Channel Materials (Particle Size Index ) Dso
The D50 particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg elevations.
17.65
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel widths
in length, with the "riffle-to-riffle" water surface slope representing the gradient at bankfull
stage.
0.0124
Channel SINUOSITY (k)
Sinuosity is an index of channel pattern, determined from a ratio of stream length divided
by valley length (SL / VL); or estimated from a ratio of valley slope divided by channel
slope (VS / S).

Bankfull DEPTH (dbkf)
Mean DEPTH of the stream channel cross-section, at bankfull stage elevation, in a
riffle section (dbkf = A / Wbkf)• 1.27
-. D
Bankfull X-Section AREA (Abkf)
AREA of the stream channel cross-section, at bankfull stage elevation, in a riffle
section.
11.18
Width/Depth Ratio (Wbkf/ dbkf)
Bankfull WIDTH divided by bankfull mean DEPTH, in a riffle section. 6.91
Maximum DEPTH (dmbkf)
Maximum depth of the bankfull channel cross-section, or distance between the
bankfull stage and Thalweg elevations, in a riffle section. 2.04
ft/ft
ft
WIDTH of Flood-Prone Area (WfPa)
Twice maximum DEPTH, or (2 x dmbkf) = the stage/elevation at which flood-prone area
WIDTH is determined in a riffle section. 97.94
Channel Materials (Particle Size Index ) D50
The D50 particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg
elevations.
154
Entrenchment Ratio (ER)
The ratio of flood-prone area WIDTH divided by bankfull channel WIDTH (WfPa/ Wbkf)
(riffle section). 11.15
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel
widths in length, with the "riffle-to-riffle" water surface slope representing the gradient
at bankfull stage. 0.0216
Channel SINUOSITY (k)
Sinuosity is an index of channel pattern, determined from a ratio of stream length
divided by valley length (SL / VL); or estimated from a ratio of valley slope divided by
channel slope (VS / S). 1.06

Cross-Section Monuments (Lat./Long.): 35.09125 Lat / 80.3265 Long Date: 07/17/07
Observers: M. Hebert, W. Knotts, J. Hines, S. Peffer Valley Type: 11
inkfull WIDTH (Wbkf)
DTH of the stream channel at bankfull stage elevation, in a riffle section. 6,06
Bankfull DEPTH (dbkf)
Mean DEPTH of the stream channel cross-section, at bankfull stage elevation, in a
riffle section (dbkf = A / WbJ 0.71
Bankfull X-Section AREA (Abkf)
AREA of the stream channel cross-section, at bankfull stage elevation, in a riffle
section.
4.3
Width/Depth Ratio (Wbkf/ dbkf)
Bankfull WIDTH divided by bankfull mean DEPTH, in a riffle section. 8.54
Maximum DEPTH (dmbkf)
Maximum depth of the bankfull channel cross-section, or distance between the
bankfull stage and Thalweg elevations, in a riffle section. 1.02
WIDTH of Flood-Prone Area (Wfpa)
Twice maximum DEPTH, or (2 x dmbkf) = the stage/elevation at which flood-prone area
WIDTH is determined in a riffle section. 23.36
Channel Materials (Particle Size Index ) D50
The D50 particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg
elevations. 11.43
Entrenchment Ratio (ER)
The ratio of flood-prone area WIDTH divided by bankfull channel WIDTH (Wfpa/ Wbkf)
(riffle section). 3.85
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel
widths in length, with the "riffle-to-riffle" water surface slope representing the gradient
at bankfull stage. 0.023
Channel SINUOSITY (k)
Sinuosity is an index of channel pattern, determined from a ratio of stream length
divided by valley length (SL / VL); or estimated from a ratio of valley slope divided by
channel slope (VS / S). 1.06

Cross-Section Monuments (Lat./Long.): 35.09139 Lat / 80.33417 Long Date: 08/08/06
Observers: Warren E. Knotts, PG & Sean Peffer, Env. Sc. Valley Type: V111
Bankfull WIDTH (Wbkf)
WIDTH of the stream channel at bankfull stage elevation, in a riffle section. 12.91 f
Bankfull DEPTH (dbkf)
Mean DEPTH of the stream channel cross-section, at bankfull stage elevation, in a
riffle section (dbkf = A / Wbkf). 1.21
Bankfull X-Section AREA (Abkf)
AREA of the stream channel cross-section, at bankfull stage elevation, in a riffle
section.
15.65
ft2
Width/Depth Ratio (Wbkf/dbkf)
Bankfull WIDTH divided by bankfull mean DEPTH, in a riffle section. 10.67
Maximum DEPTH (dmbkf)
Maximum depth of the bankfull channel cross-section, or distance between the
bankfull stage and Thalweg elevations, in a riffle section. 1.61
WIDTH of Flood-Prone Area (Wfpa)
Twice maximum DEPTH, or (2 x dmbkf) = the stage/elevation at which flood-prone area
WIDTH is determined in a riffle section. 50
Entrenchment Ratio (ER)
The ratio of flood-prone area WIDTH divided by bankfull channel WIDTH (WI,/ Wbkf)
(riffle section). 3.87
Channel Materials (Particle Size Index ) D50
The D50 particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg
elevations.
69.2
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel
widths in length, with the "riffle-to-riffle" water surface slope representing the gradient
at bankfull stage. 0.03256
Channel SINUOSITY (k)
Sinuosity is an index of channel pattern, determined from a ratio of stream length
divided by valley length (SL / VL); or estimated from a ratio of valley slope divided by
channel slope (VS / S). 1.19

Observers: Hebert, Hines & Knotts Valley Type: II
Bankfull WIDTH (Wbkf)
WIDTH of the stream channel at bankfull stage elevation, in a riffle section. 6.2 If
Bankfull DEPTH (dbkf)
Mean DEPTH of the stream channel cross-section, at bankfull stage elevation, in a
riffle section (dbkf = A / Wbkf)• 0.72
Bankfull X-Section AREA (Abkf)
AREA of the stream channel cross-section, at bankfull stage elevation, in a riffle
section.
4.45
Width/Depth Ratio (Wbkf / dbkf)
Bankfull WIDTH divided by bankfull mean DEPTH, in a riffle section. 8.61
Maximum DEPTH (dmbkf)
Maximum depth of the bankfull channel cross-section, or distance between the
bankfull stage and Thalweg elevations, in a riffle section. 1
WIDTH of Flood-Prone Area (WfPa)
Twice maximum DEPTH, or (2 x dmbkf) = the stage/elevation at which flood-prone area
WIDTH is determined in a riffle section. 37.82 f
ft2
ft/ft
Entrenchment Ratio (ER)
The ratio of flood-prone area WIDTH divided by bankfull channel WIDTH (Wfpa/ Wbkf)
(riffle section). 6.1
Channel Materials (Particle Size Index ) D50
The D50 particle size index represents the mean diameter of channel materials, as
sampled from the channel surface, between the bankfull stage and Thalweg
elevations.
11.43
Water Surface SLOPE (S)
Channel slope = "rise over run" for a reach approximately 20-30 bankfull channel
widths in length, with the "riff le-to-riffle" water surface slope representing the gradient
at bankfull stage.
0.0201
Channel SINUOSITY (k)
Sinuosity is an index of channel pattern, determined from a ratio of stream length
divided by valley length (SL / VL); or estimated from a ratio of valley slope divided by
channel slope (VS / S). 1.31
