site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
Stream relocation will take place "in the dry" and vegetation will be planted and allowed to
establish before water is rerouted into the new channel. All wetlands on the property will be
protected by silt fencing to eliminate the potential for sedimentation or accidental disturbance.
All in channel construction will take place during low flow events. Any rise or increase in flows
will require that equipment exit the channel. All disturbed slopes, including stream banks, will be
seeded and covered immediately.
VIII. Mitigation

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at

1.0 Introduction
The Pott Creek II Stream Restoration Project (Pott Creek II Site) is part of HUC 03050102
' located in Catawba County near Lincolnton, North Carolina (Figure 1). The Pott Creek II
Site provides an opportunity to restore and preserve a substantial riparian zone on lands that
have been historically used as pastureland. The restoration plan will include the stream
restoration (including the dimension, pattern, and profile) of Pott Creek and four of its
unnamed tributaries as well as Rhodes Mill Creek.
' 2.0 Goals and Objectives
The goals and objectives of this mitigation plan are:
' ? Provide a stable network of stream channels that neither aggrade nor degrade while
maintaining their dimension, pattern, and profile with the capacity to transport the
' watershed's water and sediment load.
? Improve the overall downstream water quality by reducing the amount of sediment
being produced by bank erosion, increased scour, and lack of overall riparian vegetation.
? Improve the aquatic habitat by reducing the silt and clay fines in the stteambed caused
by continual bank erosion and mass-wasting of the streambanks.
' ? Improve fish habitat with the use of natural material stabilization structures such a rock
vanes, rootwads, and a riparian buffer.
' Stream Mitigation Deliverables
This project will generate 10,054.0 Stream Mitigation Units (SMUs). The SMUs are
determined by using the formulas [SMU = (Restoration/ 1.0) + (Enhancement Level I/1.5)
' + (Enhancement Level II/2.5) + (Preservation/5.0)]. A summary of the deliverables is
presented in Table 1 below.

3.0 General Location Information
Site Description
The Pott Creek II Site is located approximately five miles west of Maiden and eight miles
southwest of Newton in southern Catawba County, North Carolina (Figure 1). It is
characterized by a variable floodplain associated with Pott Creek which is bordered by
moderately sloping terrain along both sides. Pott Creek transects the site in a southerly
direction. Several tributaries of Pott Creek drain the majority of the area associated with the
site. Elevations range from a high of 830 feet above mean sea level at the northern site
boundary, north of Paint Shop Road, to a low of approximately 785 feet above mean sea
level in the Pott Creek floodplain, downstream of the Paint Shop Road (SR 2023) crossing.

The primary land use within the study area is pastureland; however, limited forested lands
occur along the eastern side of Pott Creek.
Site History
Based on the reconnaissance of the watershed, the existing channel associated with Pott
Creek is both entrenched and unstable due to current and prior landuse activities. These
activities include several occurrences of past channelization, removal and on-going
maintenance of the riparian buffer, and continuous grazing. Channelization has been
implemented at least twice along the Pott Creek II Site; first in the late 1800's and again in
the early 1900's. Evidence of the latest extent of channelization (early 1900's) is noted on
recent aerial photography. This channelization placed the center of the channel along the
current property boundary between the Jarrett, Carter, Chucci, Propst, and Smith properties.
The date of the latest channelization is unknown at the current time; however, interviews
with the property owners indicate it was completed approximately 80 years ago. Historic
aerial photographs from both the Natural Resources Conservation Service and Catawba
County reveal the previous pattern of Pott Creek. The relic channel was located during the
initial field reconnaissance. Sedimentation, fill material, and vegetation currently comprise
the old channel. Based on the extremely long meander wavelengths and long radius of
curvatures, this reach had been altered to its unnatural state prior to the turn of the 20`h
century.
Current Property Ownership
EarthMark companies, LLC (EarthMark) currently owns the Pott Creek II Site in its entirety.
This property was created from portions of eight individually-owned parcels. With the
exception of the northeastern site boundary, a minimum buffer width of 50 feet was
purchased along both sides of the existing Pott Creek channel, its three unnamed tributaries
and Rhodes Mill Creek. Additional buffer areas were purchased to ensure that the riparian
corridor met the 50-foot buffer restriction in regard to areas where channel relocation is
proposed. An aerial photograph denoting the site and its attributes is provided in Figure 2.
Previous property owners include: Howard and Jo Jarrett, Maggie Carter, Richard and Jean
Chucci and Rachel Sigman, Matthew Speagle, Billie Susan Propst, Randy and Susan Smith,
Annette Hamrick, Michael and Samantha Hoyle, Michael and Robert Hoyle, and Rayford
Crawley.
4.0 General Watershed Information
Pott Creek and its tributaries are part of the Catawba River Basin, situated within US
Geological Survey (USGS) hydrological unit code (HUC) 03050102 and NC Division of
Water Quality (NCDWQ) subbasin 03-08-35. Pott Creek enters the project site from the
north and flows in a southerly direction approximately 6,900 linear feet across the site.
Rhodes Mill Creek and several unnamed tributaries enter Pott Creek from both sides of the
floodplain. Upstream of the site, Pott Creek collects surface hydrology from Cow Branch,
Sampson Creek, Haas Creek and several unnamed tributaries. The calculated drainage area
of Pott Creek as it enters the Pott Creek II Site is approximately 13.9 square miles (8,896
acres). Its drainage area increases to approximately 14.3 square miles (9,152 acres)
downstream at the Paint Shop Road Bridge and to 19.7 square miles (12,696 acres)
immediately downstream of the confluence with Rhodes Mill Creek at the southern property

boundary. Further downstream of the site, Pott Creek converges with Little Pott Creek
prior to draining into the South Fork Catawba River and the Catawba River.
According to the North Carolina Department of Environment and Natural Resources
(NCDENR, 1999), Pott Creek exhibits an Index of Biotic Integrity (NCIBI) rating of "Fair."
This rating notes evidence of additional deterioration including the loss of intolerant species,
fewer species, and a highly skewed trophic structure. The rating was issued in 1997
approximately one mile downstream of the Paint Shop Road stream crossing. Based on
increases in sedimentation and lack of suitable in-stream habitat, this rating is likely in the
"Poor-Fair" or "Poor" category. The surface water classification of Pott Creek and its
tributaries is Class C, denoting freshwaters protected for aquatic life propagation/protection
and secondary recreation (NCDENR, 2003). This classification is issued for the portion of
Pott Creek beginning at its headwaters and continuing downstream through the site to
approximately one mile downstream of Paint Shop Road. At this point, the creek is
classified as Class WS-IV waters which are protected as water supplies generally in
moderately to highly developed watersheds. No High Quality Waters (HQW), Water
Supplies (WS-I or WS-II), or Outstanding Resource Waters (ORW) occur at or near the
study area (NCDENR, 1999).
Landuse in the watershed is considered rural, with no known large areas of impervious
surfaces commonly associated with urban development. Agricultural and pasturelands
account for the majority of the surface area in the watershed, while forested sections exist
along the streams and steep side sloping areas.
5.0 Description of Existing Conditions
' Existing Hydrological Features
Pott Creek, Rhodes Mill Creek, and its tributaries were surveyed to determine specific
geomorphological information outlined by the Rosgen stream classification system (Rosgen,
' 1996). These surveys included longitudinal profiles, cross sections, pebble counts, and bar
samples of the existing channel. A summary of the geomorphic characteristics is included in
the Attachments.
The streams found at the Pott Creek II Site have been impacted by channelization and
dredging activities during the last two centuries. The land adjacent to the streams has been
used for cattle grazing, thus allowing significant changes to occur with the stream,
vegetation, and soils. The patterns and features found in natural, stable streams have been
replaced with straightened, featureless channels.
Pott Creek and Rhodes Mill Creek both classify as G stream types under the Rosgen stream
classification system and will be restored to a C stream type using a combination of Priority I
and II restoration. The Pott Creek tributaries represent C/G stream types. These streams
have been heavily impacted.
Geology
The Pott Creek II Site is located in the Piedmont physiographic province and underlain by
the Inner Piedmont Belt, a region consisting of metamorphic rocks. According to the NC
Division of Land Resources (NCDNR, 1985), the Pott Creek II Site is comprised of
3

' amphibolite and biotite gneiss, which are interlayered with minor layers and lenses of
hornblende gneiss, metagabbro, mica shist, and granitic rock. Narrow, rolling, interstream
divides, intermixed with steeper slopes along well-defined drainage ways, characterize the
landscape.
' Soils
The soils underlying the site and adjacent areas are mapped as the Hiwassee association,
comprised of gently sloping to moderately steep soils that have subsoil that is dominantly
' dark red, firm clay. This association is composed of approximately 70 percent Hiwassee
soils and 30 percent soil of minor extent, including Cecil, Madison, Pacolet, Enon, Wilkes,
and Appling soils on uplands, and the Congaree, Chewacla, and Wehadkee soils on
t floodplains (Brewer, 1975).
Based on the soil survey of Catawba County, Chewacla and Congaree soils dominate the site
' while the stream terraces and uplands consist mainly of Hiwassee soils (Figure 3). Chewacla
soils are classified by the Natural Resources Conservation Service (MRCS) as fine-loamy,
mixed, active, thermic Fluvaquentic Dystrudepts. These soils are somewhat poorly drained
' soils formed in recent alluvium on nearly level floodplains along streams that drain from the
Mountains and Piedmont physiographic provinces. Slopes range from 0 to 2 percent.
Chewacla soils are classified as Hydric B soils with inclusions of Wehadkee soils (Hydric A)
' in areas that are flooded for longer periods and exhibit anaerobic conditions. Congaree soils
are classified as fine-loamy, mixed, active, nonacid, thermic Oxyaquic Udifluvents. They are
deep, well to moderately well drained, moderately permeable loamy soils that formed in
' fluvial sediments. Congaree soils do not have a Hydric classification. Slopes range from 0 to
4 percent (MRCS, 2000).

Existing Vegetation and Invasive Species
The vegetation at the project site is separated into three major groupings: Piedmont
Bottomland Forest, Pastureland and Piedmont Swamp Forest (Figure 4). These groupings
are based primarily by topographical position and current land use.
Piedmont Bottomland Forest
The first grouping covers the vegetation found along the Pott Creek channel and subsequent
eastern floodplain, as well as the small area south of Rhodes Mill Creek. This vegetation,
consistent with the Shafale and Weakley's (1990) Piedmont Bottomland Forest classification,
is sparse along the channel banks; however, it increases with density across the floodplain
eastward. Dominant species include hackberry (Celtis laevigata), river birch (Betula nigra),
sycamore (Platanus occidentalis), and privet (Ligustrum sinense). Piedmont Bottomland Forests
are generally situated on floodplain ridges and terraces other than active levees adjacent to
the stream channel. They are underlain by various alluvial soils, including the Chewacla and
Congaree series. These communities are flooded; however, they are seldom disturbed by
flowing water. Bottomland forests are believed to form a stable climax forest, having an un-
even aged canopy with primarily gap phase regeneration, although the possibility of
unusually deep and prolonged flooding may make widespread mortality more likely than in
uplands.

1

Pastureland
The second grouping pertains to the pasture area west of Pott Creek and north of Rhodes
Mill Creek. This grouping consists of mainly herbaceous species including fescue (Festuca
sp.) and other grasses and weeds. Soft rush (Juncus sp.) is present in the lower areas. Active
cattle grazing restricts the overall diversity and composition of vegetation throughout this
area.
Piedmont Swamp Forest
The third grouping is situated along the northwestern edge of the site. It is associated with
the historical channel and is currently dominated by shrub-like vegetation. Tag alder (Alnus
serrulata), black willow (Salix nigra), and soft rush (Juncus ffusus) are dominant species in this
community. This area is consistent with the Piedmont Swamp Forest classification (Shafale
and Weakley, 1990). It is primarily underlain by fine to medium-textured alluvial soils,
including the Wehadkee series. The hydrology is palustrine, seasonally to frequently flooded
and may be flooded for long periods, as is the case at the Pott Creek II Site.
Invasive, or non-native species, are prevalent across the project site in the areas not affected
by grazing. Species including privet and Japanese honeysuckle (L.onicera japonica) were
observed throughout the eastern portion of the floodplain, while other species such as
multiflora rose (Rosa multiora) were observed along the stream banks and in the pasture
' areas. Box elder (Acer negundo), a native, highly competitive species, was noted across the
floodplain in the areas not affected by grazing.

Jurisdictional Streams and Wetlands
Pott Creek, Rhodes Mill Creek, and the unnamed tributaries meet the jurisdictional
definitions for perennial streams. The North Carolina Administrative Code provides a
working definition for perennial streams. Perennial streams have water flowing in a well-
defined channel for a majority of the year (greater than 90 percent of the time) (NCAC,
1999).
Jurisdictional wetland determinations were performed using the three-parameter approach as
prescribed in the 1987 Corps of Engineers Wetlands Delineation Manual (Environmental
Laboratory, 1987). Jurisdictional wetlands exist intermittently throughout the Pott Creek
floodplain. These wetlands have been identified and located on base maps. The restoration
of Pott Creek and its tributaries including Rhodes Mill Creek will not impact these wetlands.
Cultural Resources
A review of properties to be determined eligible for the National Register of Historic Places
at the State Historic Preservation Office (SHPO) was conducted for the study area and
surrounding areas. According to the files, there are no National Register properties within a
one-mile radius of the study area. In addition, the SHPO Archaeological Section was
contacted in order to determine if documented archaeological sites occur at or near the study
area. No sites were identified within a one-mile radius of the study area. A Phase I survey
has been completed to ensure that no archaeological sites exist within the project area. An
Archaeological Survey is included as an addendum to this plan. The Archaeological Survey
indicates no archaeological findings and has been submitted to the SHPO office. This
survey, as well as the SHPO's Section 106 clearance letter agreeing with the survey's findings
is included in the addendum.

Protected Species
According to the US Fish and Wildlife Service (USFWS), there is one threatened species
(dwarf-flowered heartleaf) and two federal species of concern (Catawba crayfish ostracod
and sweet pinesap) potentially occurring in Catawba County (Addendum). In addition, The
NC Natural Heritage Program (NCNHP) identifies one threatened species (bald eagle), and
five species of special concern as also potentially occurring in the county. A review of the
NCNHP database of documented occurrences did not reveal the presence of any of the
aforementioned species within a one-mile radius of the site. Field investigations did not
identify suitable habitat for the dwarf-flowered heardeaf (Hexastylis naniflora), sweet pinesap
(Monotropsis odorata), bald eagle (Haliaeetus leucocephalus), or the Catawba crayfish ostracod
(Dactyloctythere isabelae).
A letter dated March 30, 2004 from Brian Cole, USFWS, concurred there were no known
locations of any federally listed species in the immediate project area. This letter is included
in the addendum. However, he requested the opportunity to review future plans and
recommended a survey for dwarf-flowered heardeaf (Hexastylis nanaflora) given that several
occurrences of the plant are known to occur in the vicinity of the Pott Creek II Site. Since
receiving this letter, it has been determined suitable habitat for the dwarf-flowered heardeaf
will not be impacted by project implementation and a survey for this species will not be
needed.
t A letter dated March 31, 2004 from Harry LeGrand, NCNHP concurred that no known
federal or state protected species or their critical habitats occur within 1.0 mile of the Pott
' Creek II Site. A copy of this concurrence letter is provided in the Addendum.
The following information summarizes the evaluation for protected species at the project
site. The federally listed species are described in detail and formal conclusions are issued.
The federal species of concern and state listed species are summarized in Table 2.

Dwarf-flowered heartleaf (Hexasty& nanifl'ora)
Federal Listing: Threatened
State Listing: Threatened
Description:
The dwarf-flowered heardeaf inhabits acidic sandy loam soils along bluffs and nearby slopes,
hillsides and ravines, in boggy areas adjacent to streamheads and streams. It has the smallest
flowers of any North American Hexastylis (most less than 0.4 inches in length), with narrow
sepal tubes (never more than 0.28 inches wide). Its jug-shaped flowers range from beige to
dark brown in color and are sometimes greenish or purplish. Dwarf-flowered heardeaf
flowers mid-March to early June. Its leathery, evergreen leaves are dark green and heart-
shaped. Soil type is the most important habitat requirement and the plant prefers Pacolet,
Madison, or Musella soil types. It requires sunlight in early spring for maximum flowering
and seed production.
Conclusion:
Based on the above-mentioned habitat requirements, the Pott Creek II Site does not provide
the desired habitat for the dwarf-flowered heartleaf. Project construction will be limited
primarily to the open, pasture areas at the site. A vegetative reconnaissance was done as part
6

' of project requirements and did not note the presence/existence of any Hexastylis species.
The NC Natural Heritage Program also does not have any documented occurrence of this
' species within aone-mile radius of the project site. Therefore, based on these conclusions,
project implementation will not impact this species.

Description:
The bald eagle is a large raptor. The characteristic adult plumage consists of a white head
and tail with a dark brown body. juvenile eagles are completely dark brown and do not fully
develop the majestic white head and tail until the fifth or sixth year. Fish are the primary
food source but bald eagles will also take a variety of birds, mammals, and turtles (both live
and as carrion) when fish are not readily available. Adults average about three feet from
head to tail, weigh approximately 10 to 12 pounds and have a wingspread that can reach
seven feet. Generally, female bald eagles are somewhat larger than the males.
Breeding pairs of bald eagles unite for life or until the death of their mate. The breeding
season varies throughout the U.S., but typically begins in the winter for the southern
populations and progressively shifts toward spring the further north the populations occur.
The typical nest is constructed of large sticks and lined with soft materials such as pine
needles and grasses. The nests are very large, measuring up to six feet across and weighing
hundreds of pounds. Many nests are believed to be used by the same pair of eagles year
after year. Female eagles lay an average of two eggs; however, the clutch size may vary from
one to three eggs. The eggs are incubated about 35 days. The young fledge 9 to 14 weeks
after hatching and at approximately 4 months the young eaglets are on their own.
Conclusion:
Based on the above-mentioned habitat requirements, the Pott Creek II Site does not provide
the desired habitat for the bald eagle. Project construction will be limited primarily to the
open, pasture areas at the site. There are no large bodies of water in the vicinity and no
potential nesting trees that provide a clear, open pathway to and from a feeding source. No
large raptors were observed during any of the site visits and the NC Natural Heritage
Program does not have any documented occurrences within a one-mile radius of the site.
Therefore, based on these conclusions, project implementation will not impact this species.

Environmental Issues
The EarthMark Team obtained preliminary data from Environmental Data Resources, Inc.
' (EDR) regarding the potential for on-site or nearby sources of contamination. EDR
maintains an updated database of current and historical sources of contamination. All
storage tanks, whether above-ground or underground are identified, as well as superfund
sites, landfills, hazardous waste sites, and other potential hazards. No sites exist on their
database within a one-mile radius of the site. This report is on file.

1

The EarthMark Team conducted a visual reconnaissance for any Recognized Environmental
Concerns (RECs) throughout the site. The term REC means the presence or likely presence
of any hazardous substances or petroleum products on a property under conditions that
indicate an existing release, a past release, or a material threat of a release of any hazardous
substances or petroleum products into structures on the property or into the ground,
groundwater, or surface water of the property (ASTM E1527-00). None were observed. No
buildings, sheds, or other structures were noted at the Pott Creek II Site.
6.0 Reference Reach Analysis
Due to the existing unstable nature of most second, third and fourth order streams in the
Piedmont physiographic province; only one reference reach was identified. The reference
reach (UT to Fourth Creek) is situated in Iredell County, approximately 3 miles from
Statesville (Figure 5).
UT to Fourth Creek is characterized as a 1 st order stream and classifies as a rural C5 stream
type. Specific morphological data is presented in the Attachments section. Its watershed is
approximately 0.37 square miles and encompasses large tracts of undeveloped wooded land
and rural home sites. The riparian corridor associated with this stream consists of native,
woody vegetation. Dominant species included American beech (Fagusgrandifolia), ironwood
(Caoinus caroliniana), tulip poplar (Liriodendron tuloifera), flowering dogwood (Corpus florida),
spice-bush (Undera ben?Zoin), white oak (Quercus alba), and Southern red oak (Quercus falcata).
This stream was chosen due to its stable nature and relatively low bank-height ratios.
7.0 Stream Restoration Plan
Proposed Design
The restoration of Pott Creek will utilize a combination of natural channel design
methodologies with limited soil bio-engineering applications. This restoration will utilize
methods consistent with a Rosgen Priority Level II-type restoration. The Priority Level II
restoration will involve construction of a new channel at the existing elevation to the west of
1

J

the existing channel. The Final Design and Typical Channel Sections can be found in the
Attachments section. Advantages of the Priority II restoration include a decrease in bank
height and streambank erosion, establishment of riparian vegetation to help stabilize the
banks, establishment of a floodplain to help remove stress from the channel during flood
events, improvement of aquatic habitat, abatement of wide-scale flooding of original land
surface, reduction of sediment and easier downstream grade transition. The Priority II
restoration also increases pattern, stabilizes the channel profile, reduces overall shear and
restores the natural dimension. A Priority Level I restoration (reconnecting the channel to
its historical floodplain) is not feasible due to the limited relief across the site and controlling
outfall and inflow elevations. Approximately 7,050 linear feet of the channel will be restored
and relocated consistent with C-type stream channels. The newly established floodplain will
connect the historical floodplain via very low gradient slopes from the bankfull elevation
outward.
An additional 1,700 linear feet of stream restoration will be completed on four tributaries
that enter Pott Creek. The first unnamed tributary has been heavily degraded by cattle traffic
and grazing. A Priority Level I restoration is proposed on this stream. The Priority Level I
restoration is advantageous since it promotes re-establishment of the floodplain and a stable
channel. It reduces bank height and streambank erosion, reduces overall land loss, raises the
water table, decreases sediment, improves aquatic and terrestrial habitats, improves land
productivity and improves aesthetics. The second and third tributaries enter from the east
and are severely entrenched. Priority Level II restorations are proposed to restore the
dimension, pattern and profiles. The fourth unnamed tributary flows eastward and lies
immediately downstream of the confluence of Pott Creek and Rhodes Mill Creek. This
tributary shows evidence of past dredging and channelization. A Priority Level I restoration
is proposed on this stream which will allow the new channel to access the adjacent
floodplain.
Rhodes Mill Creek will be restored by construction of a channel with a proper dimension,
' pattern and profile, yielding 1,300 linear feet of restoration. The stream will undergo a
Priority Level II restoration at the upstream property limits, then transitioning into a Priority
Level I restoration approximately half way through the reach. The slope of the new channel
' will be reduced until its bankfull elevation is consistent with the adjacent floodplain on either
side.

Implementation will begin in the upper pasture area west of Pott Creek and continue
downstream through the middle pasture. The existing berms and spoil piles adjacent to Pott
Creek will be back-filled into the existing channel once the new channel is constructed and
stabilized. Excavated material associated with the new channel will also be used to fill the
existing channels on the project site. The elevation of the fill material will remain consistent
with the ground level associated with the current floodplain. Surface hydrology will be
reintroduced to the area via overbank flooding. Woody vegetation will be reestablished in
these areas.
Pott Creek's eastern floodplain is currently forested with areas of jurisdictional wetlands.
Minimal land disturbance is expected in this floodplain area.
9

A balanced cut/fill plan is proposed for the Pott Creek II Project. As a result, some areas of
the existing channels may remain intact to provide vernal pool habitat and watering areas for
terrestrial wildlife. The actual extent and location of these areas will be determined during
construction.
Sediment Transport
A stable stream has the capacity to move its sediment load without aggrading or degrading.
The total load of sediment can be divided into bedload and washload. Washload is normally
composed of fine sands, silts and clay transported in suspension at a rate that is determined
by availability and not hydraulically controlled. Bedload is transported by rolling, sliding, or
hopping (saltating) along the bed. At higher discharges, some portion of the bedload can be
suspended, especially if there is a sand component in the bedload. Bed material transport
rates are essentially controlled by the size and nature of the bed material and hydraulic
conditions (Hey and Rosgen, 1997).
The shear stress placed on the sediment particles is the force that entrains and moves the
particles. The critical shear for the proposed channel has to be sufficient to move the D84 of
the bed material. The critical shear stress was calculated and plotted on Shield's curve to
determine the approximate size of particles that will be moved (See attachments). Based on
Shield's curve, particles from 9 mm to 35 mm could be moved with an average value of 22
mm. The D84 of Pott Creek is 8.5 mm, while the D84 of Rhodes Mill Creek is 13 mm. The
Di., of Pott Creek (27 mm) and Rhodes Mill Creek (34 mm) fell within the predicted values.
Therefore, the proposed design has sufficient shear stress to move the bedload associated
with both streams. Based on Shield's curve, the first unnamed tributary can move particles
ranging from 8 mm to 18 mm. The D84 and Dioo of the first unnamed tributary are 5.2 and
18 mm, respectively. Unnamed Tributaries two, three and four have bed material
comprised of sand and silt. Critical shear stress analysis indicates excess shear at bankfull;
however, the use of structures, channel pattern, and vegetation will maintain channel
stability.
Flood Analysis
Portions of the Pott Creek II Site, including the channel of Pott Creek and its immediate
floodplain are located within the Federal Emergency Management Association's (FEMA)
approximate 100-year flood boundary, as depicted on Figure 6 (FEMA, 2004). These areas
are inundated by the 100-year flood where base flood elevations have not been determined.
The remainder of the site has not been mapped.
Approximate limits of flooding for the existing and proposed channels were determined
using HEC-RAS software from the US Army Corps of Engineers Hydrologic Engineering
Center. Water surface profiles for the 2-year, 5-year, 10-year, 25-year, 50-year, and 100-year
storm events were computed (See Attachments).
The proposed channels will raise flood stage in some portions of the reach, but mainly for 2
and 5-year storm events. This increase primarily occurs along Rhodes Mill Creek however;
the property encompassing the entire site provides adequate flood storage and prevents any
hydraulic trespass on adjacent property owners. This change in flood stage caused by the
proposed channel for Rhodes Mill Creek is listed in the chart below.

Proposed Construction Sequence
Construction of the project will be carried out in two phases for maximum vegetation
survival, channel stability, and sediment control requirements. During the first phase, the
new channel sections of Pott Creek, its tributaries and Rhodes Mill Creek will be constructed
and their adjacent buffer areas will be graded, ripped, and planted during the vegetation
dormancy period. Stabilization structures, including cross vanes, j-hook vanes, single-arm
rock vanes, and rootwads, will be placed within the new channel and all channel features will
be constructed. Spoil material from all newly excavated channels will be stockpiled along the
upland areas adjacent to the existing channels and stabilized with a temporary seed mix.
Grading of the first phase is expected to be completed by November 2004. During early
2005 and once vegetation has become established, the second phase will be initiated. Flow
from the existing channels associated with Pott Creek, its unnamed tributaries and Rhodes
Mill Creek will be diverted into the new, stabilized channels. Clay plugs will be installed
intermittently through sections of the old channel and the existing levees, spoil piles, and
borrow material will be placed in the old channel. Removal of minor on-site vegetation is
anticipated to reconnect the new floodplain with the existing terrace. Prior to April 2005,
the newly restored floodplains will be planted with native vegetation based on the reference
site and agency comments.
8.0 Typical Drawings
Four different structure types made of natural materials will be installed in the stream
channels. These structures include single-arm rock vanes, j-hook rock vanes, cross vanes
and rootwads. These will be composed of natural materials either on-site or from off-site
locations. These details can be found in the Attachments.
Single-Arm Rock Vanes
These structures are designed to dissipate the secondary circulation cells which cause stress
in the near bank region. They also force the thalweg away from the bank and towards the
middle of the channel. These structures are placed on the outsides of meanderbends.
Footer rocks are placed on one side of the channel bottom for stability. More rocks are then
placed at an angle to the streambank, gradually inclining in elevation until they are located
above the bankfull surface directly adjacent to the streambank.
J-Hook Rock Vanes
These structures are designed to dissipate the secondary circulation cells which cause stress
in the near bank region. They also force the thalweg away from the bank and towards the
middle of the channel. Similar in design to single-arm rock vanes, these structures are placed
on the outsides of meanderbends. Footer rocks are placed on one side of the channel
bottom for stability. More rocks are then placed at an angle to the streambank, gradually
inclining in elevation until they are located above the bankfull surface directly adjacent to the
11

i

l

streambank. Additional rocks are placed in the channel to give the structure a "J" shape.
These extra rocks are added to maintain the pool and provide additional fish habitat.
Cross Vanes
These structures serve to maintain the integrity and composition of the riffle while
promoting scour along the center of the channel, away from the adjacent banks. The design
shape is roughly that of the letter "U" with the apex situated on the upstream side in the
riffle section. Footer rocks are placed in the channel bottom for stability. Rocks are then
placed on the footer rocks in the middle of the channel at approximately the same elevation
as the design streambed. Rocks are then placed at an angle to the stream bank on either side
of the channel. These rocks gradually incline to the bankfull elevation. Water flowing
downstream is forced over these rocks towards the middle of the channel on either side of
the structure, effectively scouring a pool immediately downstream. Cross vanes are used
primarily used for stabilization and grade control, but the structures also provide habitat.
Rootwads
The objectives of these structures are to: provide in-stream and overhead cover for aquatic
organisms, including fish; provide shade, detritus and terrestrial insect habitat; and provide
minimal protection of the streambank from erosion. Generally, a footer log and boulders
are placed on the channel bottom and abut the streambank along the outside of the
meanderbend. This provides support for the rootwad and stability (minimal) to the
streambank. A large tree rootwad (or root-ball) is then placed on the streambank with
additional boulders and rocks on either side for stability. Flowing water is deflected away
from the bank and towards the center of the channel.
9.0 Stream Riparian Planting Plan
' The planting plan for the riparian buffer of the Pott Creek II Site will provide post-
construction erosion control and riparian habitat enhancement. The riparian buffer will
include native species appropriate for the Piedmont physiographic province, which have
been identified at the reference site and at the Pott Creek II Site. Native species of the area
will be selected for local conditions found at the project site. Plants within the floodplain
will be flood tolerant to accommodate for periodic flooding events throughout the year and
in the long-term. A variety of shrubs and trees will be planted to provide cover and habitat
for wildlife.
Shrubs and trees with extensive, deep rooting systems will assist in stabilizing the banks in
the long term. Native grasses, transplants, and live stakes will be utilized at the site for
immediate stabilization. Vegetation will be planted in layers similar to layers found at the
local reference site. Vegetative layers will include a shrub edge-layer immediately adjacent to
the stream and a forest canopy layer upslope of the shrub layer. Colonization of local
herbaceous vegetation will also occur.
Trees and shrub species will include, but not be limited to species typical of the Piedmont
physiographic province: river birch (Betula nigra), sugarberry (Celtis laevigata), persimmon
(Diospyros virginiana), green ash (Fraxinus pennsylvanica), blackgum (Nyssa sylvatica), sycamore
(Platanus occidentalis), water oak (Quercus nigra), willow oak (Quercus pbellos), black willow (Salix
nigra), tag alder (Alnus serrulata), ironwood (Carpinus caroliniana), buttonbush (Cepbalantbus
' occidentalis), silky dogwood (Corpus amomum), spicebush (Lindera bmZoin), silky willow (Salix
12

sericea) and yellow-root (Xanthorhi5,,a simplicissima). Actual quantities of the woody vegetation
will depend upon availability at the construction period. Locations of site-specific species
are presented in the final designs.
The Pott Creek II Site will be stabilized with a native grass mix and erosion control matting
' along the new created streambanks. Silky dogwoods and black willows will be live-staked on
the channel banks on four-foot centers throughout the entire length of the restored stream
channels. Shrub species will be planted in staggered rows on the upslope on random eight-
foot centers. Trees will be planted as bare root stock, tubelings, and/or containerized
material on random eight-foot centers at a frequency of 680 stems per acre. Planting of
species will utilize dormant plant stock and will be performed to the extent practicable
between December 1" and March 151`'.
Transplants, particularly alders, willows, and birches will be utilized in applicable areas where
the stock is plentiful to provide immediate channel stabilization. The transplants will be
strictly placed along the outsides of the meanderbends where increased shear stresses are
anticipated. The overall number of transplants is not known at this time. Determinations
' will be made during the construction period as to which species will be selected for
transplanting.
10.0 Stream Monitoring Plan
Monitoring will determine the degree of success the mitigation project has achieved in
meeting the objectives of providing proper channel function and increased habitat quality.
' This monitoring data will provide the Ecosystem Enhancement Program (EEP) and
resource agencies with evidence that the goals of the Pott Creek II project have been met.
Monitoring of the site will include an assessment of geomorphology and riparian vegetation
at least once each year for a total of five years. Monitoring reports will be submitted
annually to the EEP by December of each year. The monitoring reports will include detailed
analysis of the new stream and floodplain, plant survivability, photos, and photo location
' points as well as any problems and their respective remedial measures. In the event that
success criteria are not met, remedial measures will be developed, submitted to the EEP and
installed to achieve success.
Upon completion of the project, an as-built channel survey will be conducted. The survey
will document the dimension, pattern, and profile of the restored channel. Permanent cross
sections will be established at an approximate frequency determined by the EEP. The
locations will be selected to represent approximately 50% riffle and 50% pool areas. The as-
built survey will include photo documentation at all cross sections, a plan view diagram, a
longitudinal profile, vegetation information and pebble counts. Since the restored channel
of Pott Creek will extend nearly 6,000 linear feet, the profile will be conducted for
approximately 3,000 linear feet; however, the entire reaches of both tributaries and Rhodes
Mill Creek may be assessed.
Stream Channel Assessment
The EarthMark Team will evaluate the restored sections of Pott Creek and its associated
tributaries in regard to overall channel stability. Since streams are considered as "active" or
"dynamic" systems, restoration is achieved by allowing the channel to develop a stable
' dimension, pattern, and profile such that, over time, the stream features (riffle, run, pool,
13
glide) are maintained and the channel does not aggrade or degrade. Minor morphologic
adjustments from the design stream are anticipated based on the correlation of reference
reach data, excessive sediment deposition from upstream sources, and on-going changes in
land use within the watershed.
Vegetation
Vegetation requirements state that 260 stems/acre must be viable for success after the five
year monitoring period. Should the performance criteria outlined above not be met during
the monitoring period, the EarthMark Team will provide the EEP with their remediation
proposal, detailing corrective actions and/or maintenance actions proposed and an
implementation schedule for said actions, planned to meet the criteria. Upon review and
approval/modification of said corrective measures by the EEP and the regulatory agencies,
the EarthMark Team will implement the necessary corrective measures.
Frequency
All monitoring reports will be submitted to the EEP's designated representative for
coordination with the appropriate regulatory agencies on an annual basis. Reports will be
submitted to the EEP by December 15 of each year. The year of construction will have two
submittals, one being the As-Built drawings and the second being the First Year Annual
Monitoring Report. It is understood that the EEP will coordinate any necessary monitoring
report submittals with the regulatory agencies. If monitoring reports indicate any
deficiencies in achieving the success criteria on schedule, a remedial action plan will be
included in the annual monitoring reports. The EarthMark Team will be available to
coordinate any agency site visits, both before and after restoration activities have been
completed. Vegetative monitoring will be conducted during the summer months of each
monitoring year.
Monitoring Data
Monitoring data for each monitoring year will consist of the following:
1. Stream Channel Assessment
Channel stability
2. Vegetation Data
Number of stems/acre of woody species
Percent of survival of planted woody species
Species composition, including non-dominants
Quantitative measure of noxious species
Overall condition of the planted species
Photo reference locations of each plot
Reporting
Monitoring results will be documented on an annual basis, with the associated reports
submitted to the EEP. Both the EarthMark Team and the EEP in coordination with the
appropriate regulatory agencies will determine when the performance standards have been
achieved at the Pott Creek II Site. If standards are not met, the EarthMark Team will
perform appropriate remedial activities to satisfy the EEP.

Noxious Species
Noxious species will be identified within the restored areas and controlled so that none
become dominant species or alter the desired community structure of the site. If noxious
plants are identified as a problem at the site, the EarthMark Team will develop a species-
specific control plan for approval by the EEP prior to implementation.
Through coordination with the EEP during the five-year monitoring period, the EarthMark
Team, where necessary, will remove, treat, or otherwise manage undesirable plant or animal
species, including physical removal, use of herbicides, live trapping, confining wires, or nets.
Where necessary, the site will be fenced to keep cattle out of the mitigation areas.
All vegetation removal from the site shall be done by mechanical means only unless the EEP
has first authorized the use of herbicides or algaecides for the control of plants in or
immediately adjacent to the site.
11.0 Stream Success Criteria
Based on the Classification Key for Natural Rivers (Rosgen, 1996), restoration activities will
ultimately result in the classification of a C-stream type for Pott Creek, its associated
tributaries and Rhodes Mill Creek. These stream types are slightly entrenched, meandering,
sand/small gravel dominated, riffle-pool channels with well developed floodplains. The
riffle-pool sequence for this stream type averages five-to-seven bankfull channel widths in
length. The streambanks are generally composed of sandy material, with stream beds
exhibiting little difference in pavement and sub-pavement material composition. Rates of
lateral migration are influenced by the presence and condition of riparian vegetation. The C-
stream type, characterized by the presence of point bars and other depositional features, is
very susceptible to shifts in both lateral and vertical stability caused by direct channel
disturbance and changes in the flow and sediment regimes of the contributing watershed.
As a result, stream success criteria will be based on overall stability. It is expected that
natural channel adjustment will occur throughout the restored reaches; however, excessive
adjustment and potential stream instability will be judged to be occurring if the width/depth
ratio is measured to be greater than 15, the bank height ratio is greater than 1.4, radius of
curvature ratio is less than 1.4 or the development of headcuts occur.

ABSTRACT
' The Louis Berger Group, Inc., has completed an archaeological survey for EarthMark Companies, LCC,
in association with the proposed Pott Creek R Stream Restoration Project (TIP No.: R-999WM; State
Project No.: 8.1777741), Catawba County, North Carolina. As part of a transportation-related project,
' approximately 8,200 linear feet (2,499 meters) of existing stream and adjacent wetland areas along Pott
and Rhodes Mill creeks will be restored for the purposes of mitigation.
' The archaeological survey was limited to the areas that will be disturbed by the stream restoration. These
areas were defined by EarthMark as the study corridor and include (1) a 100-foot-wide (30-meter)
corridor on the west bank of Pott Creek extending along the creek for approximately 6,500 feet (1,981
' meters), (2) an approximately 100- to 150-foot (30- to 46-meter) variable-width corridor on the north
bank of Rhodes Mill Creek extending along the creek from its juncture with Pott Creek for a distance of
approximately 1,500 feet (457 meters), and (3) a 100-foot-wide (30-meter) corridor on the west side of
Pott Creek extending along a small unnamed tributary of Pott Creek for a distance of approximately 200
' feet (60 meters). The total area of the study corridor was approximately 20 acres (8 hectares).
The objective of this survey was to identify any archaeological resources within the study corridor, and
' archaeological sites that did not contain intact deposits were to be evaluated for inclusion in the National
Register of Historic Places. The archaeological fieldwork was conducted between March 29 and March
31, 2004, with Lee Tippett serving as Project Archaeologist, assisted by Field Archaeologists Tracy
Jones, Robert Menke, and William Weir. The fieldwork required 12 person days to complete. A total of
83 shovel tests and four auger tests were excavated along five shovel test transects. In general, the relief
within the study corridor consists of a uniform floodplain with few elevated, well-drained land surfaces.
These sediments showed evidence of disturbance, probably from a combination of timber harvesting and
' stream bed canalization. Evidence of recent land-clearing activities included several large piles of
discarded timber.
' No artifacts, cultural deposits, cultural features, or buried land surfaces were identified in any of the
shovel tests or auger tests or on the exposed land surfaces. Based on these findings, it is Berger's
recommendation that no further archaeological work is warranted.

1. INTRODUCTION
' The Louis Berger Group, Inc. (Berger), Cary, North Carolina, has completed an archaeological survey for
EarthMark, LCC (EarthMark), in association with the proposed Pott Creek H Stream Restoration Project
(TIP No.: R-999WM; State Project No.: 8.1777741), (Pott Creek), located about 6 miles west of Maiden,
' Catawba County, North Carolina (Figure 1). As part of a transportation-related project, approximately
8,200 linear feet (2,499 meters) of existing stream and adjacent wetland areas along Pott and Rhodes Mill
creeks will be restored for the purposes of mitigation (Figure 2).
' The archaeological survey was limited to the areas that will be disturbed by the stream restoration. These
areas were defined by EarthMark as the study corridor and include (1) a 100-foot-wide (30-meter)
corridor on the west bank of Pott Creek extending along the creek for approximately 6,500 feet (1,981
' meters), (2) an approximately 100- to 150-foot (30- to 46-meter) variable-width-corridor on the north
bank of Rhodes Mill Creek extending along the creek from its juncture with Pott Creek for a distance of
approximately 1,500 feet (457 meters), and (3) a 100-foot-wide (30-meter) corridor on the west side of
' Pott Creek extending along a small unnamed tributary of Pott Creek for a distance of approximately 200
feet (60 meters) (Sauls 2004) (see Figure 2). The total area of the study corridor was approximately 20
acres (8 hectares).
' The objective of this survey was to identify any archaeological resources within the study corridor, and
archaeological sites that did not contain intact deposits were to be evaluated for inclusion in the National
' Register of Historic Places. Information obtained through research was used to characterize the cultural
resource potential of the study corridor and to develop cultural contexts for evaluating any archaeological
resources that might be located within the study corridor. Research was conducted at the Office of State
Archaeology (OSA) within the North Carolina State Historic Preservation Office (SHPO) to determine if
' any previously recorded archaeological resources are located within a 2-mile (3.2-kilometer) radius of the
study corridor. Research was also conducted at the Survey and Planning Branch of the North Carolina
SHPO; the North Carolina State Archives; the North Carolina State Library; the North Carolina
' Department of Environment and Natural Resources, Division of Soil and Water Conservation; the North
Carolina Geological Survey; and the Patrick Beaver Memorial Library (Hickory, North Carolina).
' Field investigations were initiated with surface reconnaissance of the study corridor to determine the
medium- to high-potential areas within the study corridor. The property owner was contacted by
telephone and in person prior to the initiation of the fieldwork. In addition to the surface reconnaissance,
' Berger used systematic shovel tests along with auger tests to determine if any intact cultural remains
could be identified within the study corridor. A total of 83 shovel tests and four auger tests were
excavated.
' Fieldwork began on March 29, 2004, and continued until March 31, 2004. Eric Voigt served as Project
Manager, and Lee Tippett served as Project Archaeologist, assisted by Field, Archaeologists Tracy Jones,
Robert Menke, and William Weir. Completion of the work took 12 person days. Mr. Tippett authored
' the report. Anne Moiseev provided editing, and Jacqueline Horsford produced the graphics.
The archaeological survey and evaluation conducted for this project are pursuant to the National Historic
' Preservation Act of 1966 (as amended through 1999); the Archaeological and Historic Preservation Act of
1974; Executive Order 11593; Title 36 of the Code of Federal Regulations, Parts 660-666 and 800 (as
appropriate); and Section 4(f) of the Department of Transportation Act (23 CFR 771). The field
' investigations and the technical report meet the qualifications specified in the Secretary of the Interior's
Standards and Guidelines for Archeology and Historic Preservation (48 Federal Register 44716-44742)
(United States [U.S.] Department of the Interior 1983). The qualifications of the Project Archaeologist

II. ENVIRONMENTAL CONTEXT

I
The study corridor is located in Catawba County, in the west central part of the Piedmont physiographic
province of North Carolina (Fenneman 1938). The topography of the county varies from gently sloping
hills to very steep uplands, with elevations ranging from 760 feet (232 meters) above mean sea level
(amsl) on the Catawba River floodplain to 1,812 feet (552 meters) ams] on the crest of Baker Mountain
(Brewer 1975:44). In general, the Piedmont province consists of well-rounded and low-rolling ridges that
are oriented generally northeast-southwest; elevations range from 300 to 400 feet (91 to 122 meters) amsl
along the eastern portion, to as high as 1,500 to 2,000 feet (457 to 610 meters) amsl at the base of the
Blue Ridge escarpment (Stuckey and Steel 1953:1). Elevations in the study corridor range from 780 feet
(238 meters) amsl near the creek and its floodplain to 800 feet (244 meters) amsl near ridge sideslopes.
The basement rocks of the Piedmont are arranged in a series of northeast trending belts that gradually
slope to the east at a rate of about 20 feet (6.0 meters) per mile near the edge of the Coastal Plain.
Between the Appalachian Mountains and the Coastal Plain, these structures are the Blue Ridge Belt,
Brevard Belt, Inner Piedmont Belt, Kings Mountain Belt, Charlotte Belt, and Carolina Slate Belt
(Overstreet and Bell 1965). The Pott Creek section of southern Catawba County lies within a zone
characterized by rocks of amphibolite and biotite gneiss, interlayered with minor layers and lenses of
hornblende gneiss, metagabbro, mica schist, and granitic rocks (North Carolina Geological Survey 1985).
These rocks have been altered from their original igneous and sedimentary mineralogical states by
medium- to high-grade metamorphism (Horton and McConnell 1991:44).
The Catawba River is the main drainage for the northern and eastern portions of the county. The county
is also drained by a series of northwest to southeast trending drainages, including Jacob Ford and Clark,
Lyle, McLin, Ball, and Maiden creeks (Brewer 1975:44). Pott Creek rises in southern Catawba County
and joins the South Fork of the Catawba River in adjacent Lincoln County (Powell 1968:395).
The United States Department of Agriculture (USDA) has classified one soil association, the Hiwassee
Association, within the study corridor. This association makes up about 19 percent of the county, and is
composed of about 70 percent, Hiwassee soils and 30 percent soils of minor extent, including minor
floodplain soils such as soils of the Congaree, Chewacla, and Wehadkee series (Brewer 1975:3). The
specific soil series in the study corridor include Chewacla loam, Congaree Complex, and minor amounts
of Cecil clay loam (Brewer 1975). Chewacla soil occurs on nearly level, somewhat poorly drained soils
on floodplains formed of recent alluvium (Brewer 1975:9). The Congaree soils are described as nearly
level, well-drained soils on floodplains. These soils are formed of recent alluvium (Brewer 1975:10).
Cecil clay loam occurs on slopes of 10 to 25 percent, and is eroded and well-drained (Brewer 1975:9).
This soil type is often found on the lower slopes of upland ridges and knolls.
The climate of Catawba County is temperate, based on its position between the Blue Ridge Mountains to
the west and the Atlantic Ocean to the east. Annual rainfall varies significantly from year to year,
averaging about 49 inches (124 centimeters) (Brewer 1975:45). Winter temperatures frequently fall
below 32 degrees Fahrenheit (0 degrees Celsius) for brief periods of time. In summer, the average daily
temperature is about 90 degrees Fahrenheit (32 degrees Celsius). Winter snowfall amounts average about
8 inches (20.32 centimeters) annually (Brewer 1975:45).
The floodplain of the Pott Creek project is currently being used to graze livestock (Plate 1). The
vegetation in the study corridor is dominated by species of grasses, sedges, and rushes that have taken
advantage of the disturbed habitat. A few trees, including black walnut, yellow poplar, willow, and water
oak, have become established on the banks of Pott and Rhodes Mill creeks (Plate 2). Minor amounts of
steeply sloping terrain, existing wetlands, and disturbed areas were encountered within the study corridor
(Plates 3, 4, and 5).

III. CULTURAL CONTEXT
A. PREHISTORIC OVERVIEW
1. Paleoindian Period (9500 to 8000 BC)
Paleoindian are the first known human populations to have occupied the region that is now North
Carolina. Archaeologists have characterized Paleoindian populations as small nomadic or seminomadic
bands with subsistence/settlement strategies based on hunting and the collection of wild foods.
Archaeological markers of the Paleoindian period consist chiefly of distinctive projectile point types, such
as Clovis, Cumberland, Quad, Dalton, Hardaway, Simpson, and Suwannee (Anderson 1992a:7-9).
Goodyear et al. (1979:91) note that formal variability among Paleoindian point types may reflect
chronological or spatial differences. A marked preference for high-quality cryptocrystalline lithic raw
materials is also evident in Paleoindian toolkits (Goodyear 1979).
The principal subsistence focus of Paleoindians in eastern North America appears to have been herd
animals, such as caribou, although solitary animals, such as elk and moose, were probably also hunted
(Gardner 1981). Evidence of the importance of hunting among Paleoindian subsistence patterns is
provided by toolkits of the period, which include projectile points, knives, scrapers, gravers, and other
implements typically associated with the hunting and processing of faunal resources (Goodyear et al.
1979:93-96). Data from the Northeast, however, suggest that fish and wild plants may have also been
components of the Paleoindian diet (Dent 1981, 1991; Kelly and Todd 1988; Smith 1986). Thus, a
generalized subsistence strategy probably prevailed among these Paleoindian groups (Goodyear et al.
1979:19-44; Ward and Davis 1999:34-37).
The Paleoindian settlement strategy is typically characterized as highly mobile. In reviewing the issue of
mobility, Anderson (1992b:28-35, 44-46) calls attention to recent arguments suggesting that Paleoindian
groups in the Southeast formed relatively stable populations in particular subregions. Evidence from the
Middle Atlantic region suggests that Paleoindian groups may have focused their seasonal settlement/
subsistence activities on sources of high-quality lithic raw materials. Base camps were situated in
proximity to quarry sites where lithic materials were obtained, while smaller exploitative camps radiated
at varying distances from the base camps (Gardner 1974, 1981). Goodyear et al. (1979) observe that
evidence of Paleoindian settlement in the Southeast appears to reflect strategies for procuring and
processing lithic raw materials.
Although no Paleoindian points have been recovered in Catawba County, they have been reported from
other counties in western North Carolina (Perkinson 1971, 1973:55). Daniel (2001) notes that the density
of Paleoindian points in the Appalachian Mountains indicates that this region may have been as
intensively occupied as the Piedmont. Metavolcanic raw material is underrepresented in the mountains,
while the number of chert points exceeds expectations. Raw material frequencies are reversed in the
Piedmont. This pattern of stone utilization and point distribution suggests that two Paleoindian settlement
systems are represented, one focused on the Ridge and Valley and Appalachian Mountains and the second
occupying the Piedmont and Coastal Plain (Daniel 2001). Interaction and movement between the two
physiographic provinces appear to have been limited (Daniel 2000).
Few Paleoindian sites with intact stratigraphy and extensive assemblages have been excavated in North
Carolina. One of the most important is the Hardaway Site (31ST4), in Stanly County, which yielded the
earliest cultural remains that have been excavated from stratified deposits in North Carolina.
Archaeologists disagree about the age of the site, but most agree that it dates to at least the late portion of
the Paleoindian period and that it also contains a significant Early Archaic component (Ward and Davis
1999:34-37). Joffre Coe's excavation of the site began in 1948, but large-scale excavation did not begin
I

Archaeological Survey Pon Creek 11 Stream Restoration Project, Catawba County, N. C.
until the 1950s (Coe 1964:57-60). Unfortunately, modern looting of the Hardaway Site has been
extensive and has resulted in the loss of much stratigraphic information. Despite this disturbance, Coe
and other archaeologists recovered large numbers of artifacts from the site (Coe 1964; Daniel 1998:129).
One other Piedmont project has resulted in the recovery of Paleoindian material. In the 1970s large-scale
block excavations were conducted at two sites (Sites 31CH8 and 31CH29) along the Haw River in
Chatham County in the Central Piedmont, which produced Hardaway-Dalton projectile points from
stratified deposits (Claggett and Cable 1982).
A statewide survey of Paleoindian points has recently been used to formulate hypotheses about
Paleoindian settlement range in North Carolina (Daniel 2000, 2001). It has been demonstrated that the
frequency of Paleoindian points in the eastern Piedmont and along the fall line is greater than would be
expected given the land area involved (Daniel 2001). Two factors account for this distribution: (1)
erosion has exposed more land surfaces in the Piedmont, increasing the visibility of Paleoindian sites; and
(2) the eastern Piedmont is the source area for Uwharrie rhyolite (Daniel 1998:178). The second factor
assumes that the location of sources of high-quality stone influenced Paleoindian settlement (Goodyear et
al. 1979). A higher than expected density of Paleoindian sites along the fall line has also been noted in
Georgia and South Carolina (Anderson 1992a:75; Charles 1986:16). The fall line appears to have
functioned as an ideal setting for interaction between Paleoindian groups traveling along and between
major river drainages (Anderson 1995:15).
2. Archaic Period (8000 to 1000 BC)
Archaeologists divide the Archaic period into three subperiods: Early Archaic (8000 to 6000 BC), Middle
Archaic (6000 to 3000 BC), and Late Archaic (3000 to 1000 BC). As the Southeastern climate moderated
from late glacial conditions into more temperate ranges closer to modern conditions, Archaic peoples
developed a diversified subsistence economy focused on seasonal hunting, fishing, and collecting of wild
plant foods. Increased efficiency in resource exploitation resulted in gradual development of more
complex societies, regional variability in cultures, development of trade and exchange networks, and
population growth. Paralleling this expansion of adaptive strategies was an increase in the size and
complexity of sites and further development and elaboration of material culture. In addition, a wider
variety of raw materials was used in the production of both flaked and groundstone tools.
a. Early Archaic Period (8000 to 6000 BC)
In terms of settlement and subsistence patterns, the Early Archaic period is interpreted as a continuation
of the preceding Paleoindian period. The Early Archaic is marked primarily by adaptations to changing
environmental circumstances and an increased use of smaller species of fauna. The period is also marked
by the introduction of a variety of small corner-notched projectile points, such as Kirk and Palmer points,
and steeply retouched unifaces (Coe 1964:120-122). The distinction between the Kirk and Palmer corner-
notched types depends heavily on size and the presence or absence of basal grinding (Tippett 1992). Both
of these attributes are suspect, given the tendency of size to be affected by raw material type,
manufacturing trajectory, and use life (Oliver 1981), and the fact that basal grinding has been observed on
specimens that otherwise fit the Kirk corner-notched archetype, further reducing the utility of this
subjective characteristic (Chapman 1975:117, 1977:48). Diagnostic artifact types of the Early Archaic
include Taylor, Big Sandy, Palmer, Kirk, LeCroy, and St. Albans projectile points (Anderson and Joseph
1988; Coe 1964:67-70). The Early Archaic toolkit also includes a variety of adzes, drills, gravers,
scrapers, and perforators (Coe 1964; Daniel 1994, 1998).
By the Early Archaic period ameliorating climatic conditions associated with the early post-Pleistocene
would have resulted in a homogeneous resource structure across much of the Southeast (Sassaman et al.
1990). Early Archaic settlement data suggest that populations of this period were organized into small
groups that possessed high residential mobility. The hunter-gatherer subsistence base of the preceding
10

' period persisted into the Early Archaic. Anderson and Hanson (1988) suggest that settlement strategies
during the period varied on a seasonal basis. During the winter Early Archaic groups followed a logistical
strategy whereby populations were concentrated in residential camps and critical resources were obtained
' during forays to points where such resources were present. During the remainder of the year the
settlement/subsistence strategy was characterized by foraging, and residential sites were moved to
resource locations as specific resources became available. The annual round would have included regular
' congregations of these smaller groups, probably in the fall, for information exchange and mate
acquisition. A linear range between geophysical zones was characteristic of the annual rounds; groups
roamed along the Atlantic coast in the winter through spring and in the uplands of the Piedmont in the
' summer through fall. These movements, however, were concentrated within major drainages that
extended from the Piedmont to the Coastal Plain (Anderson and Hanson 1988).
Some archaeologists have questioned the validity of such a seasonally mobile model, given the rich
' diversity of natural resources in the Piedmont (Ward 1983; Ward and Davis 1999:58). An alternative
hypothesis proposes that people were "tethered" to the Uwharrie Mountain rhyolite sources and moved
between drainages in the southern Piedmont (Daniel 1998:202-204). Aside from the Hardaway Site, there
' have been no other Piedmont sites identified with intact deposits that could be useful in addressing
questions about Early Archaic settlement patterns (Ward and Davis 1999:58).
I b. Middle Archaic Period (6000 to 3000 BC)
Native population and territoriality gradually increased during the Middle Archaic subperiod. Stemmed
t projectile points of the Stanly, Morrow Mountain, and Guilford varieties are diagnostic of the Middle
Archaic. These points were originally identified at the Lowder's Ferry Site (31ST7) and the Doerschuk
Site (31MG22). Both sites contained intact Middle Archaic deposits below Woodland layers (Coe 1949,
' 1964). Other new Middle Archaic tools include the atlatl and chipped-stone axes (Ward and Davis
1999:63).

In contrast with the preceding Early Archaic period, when settlement patterns encompassed broad linear
territories that crosscut geophysical zones to exploit specific seasonal resources, Middle Archaic
settlement patterns reflect limited movement between regions. Middle Archaic populations instead
expanded their settlement ranges within geophysical regions and exploited more diverse resources.
Settlement and artifact data from this period suggest "a strategy of small co-resident group size, frequent
residential movement, generalized subsistence, low-investment technology, and social flexibility"
(Sassaman et al. 1990:10). Sassaman and others assert that Middle Archaic populations were mobile and
changed residential locations frequently to take advantage of specific resources as they became available
(Blanton and Sassaman 1989; Sassaman 1988; Sassaman et al. 1990). According to Sassaman (1988),
tools used in resource procurement and processing were of an expedient type and were manufactured
from local materials. Blanton and Sassaman (1989:61-62) have noted that there are more sites in
interriverine zones, but the size of sites and the artifact density are greater in floodplain settings. They
have also noted that in South Carolina more Middle Archaic sites are found in the Piedmont than in the
Coastal Plain. Similar results have been noted for North Carolina (Ward and Davis 1999:63).
A warmer and drier climate may also have been the reason for a change in the settlement and subsistence
pattern. This climatic change, known as the Altithermal or Climatic Optimum, created a less predictable
environment. Frequent moves may have been necessary to locate specific food resources as they came
into season (Claggett and Cable 1982).
Archaeological surveys conducted in surrounding counties have identified sites with Middle Archaic
occupations. In archaeological surveys of portions of McDowell and Rutherford counties, Morrow
Mountain was the most frequently encountered artifact type in upland and flood plain contexts, while
Guilford types were recovered on lower slopes and on floodplains (Jurney and Downing 1974:110).
11

Archaeological Survey Pon Creek 11 Stream Restoration Project, Catawba County, N.C.
' Middle Archaic sites, represented by Morrow Mountain and Guilford types, have been identified in
upland contexts (e.g., Sites 31CW132 and 31CW140) in Caldwell County (Ayers and Kooiman 1996).
' c. Late Archaic Period (3000 to 1000 BC)
Trends toward increasing population, group size, organizational complexity, and sedentism distinguish
' the Late Archaic period. The diagnostic artifact of the Late Archaic is the Savannah River stemmed
projectile point. In the North Carolina Piedmont and southern Appalachian Mountains, such points
became smaller over time (Keel 1976; Oliver 1981). A variety of scrapers, drills, grooved groundstone
' axes, harnmerstones, netsinkers, polished atlatl weights, and stone mortars are also common (Chapman
1981:48; Davis 1990:225).
' Another hallmark of the Late Archaic is the introduction of steatite (or soapstone) as a raw material.
Initially, this material was used as "cooking stones" or as weights for atlatls. Indirect cooking consisted
of heating the cooking stones before placing them in perishable containers (Ward and Davis 1999:64). A
change occurred during the second half of the Late Archaic period, when soapstone was used to make
' bowls that were then used to cook food directly over the fire (Coe 1964; Wood et al. 1986:324). Carved
soapstone vessels and vessel fragments have been recovered from Late Archaic contexts at the Warren
Wilson Site (31BN29) (Keel 1976:187). In North Carolina the introduction of ceramic technology
' followed the Savannah River occupation; at Doerschuk and Gaston, the Late Archaic Savannah River
occupation was separated from the ceramic-bearing Early Woodland Badin occupation by sterile alluvial
sediments (Coe 1964; Ward 1983).
' Subsistence data from the Late Archaic period are lacking from Piedmont sites; however, the location of
base camps with middens, such as the Doerschuk, Lowder's Ferry, and Gaston sites, indicates a
' preference for living along major waterways. A variety of animals, including fish, turtles, migratory
birds, white-tailed deer, bear, and small mammals, would have existed in such an environment. Wild
fruits, nuts, and berries would have been gathered on a seasonal basis (Ward and Davis 1999:67).
' Late Archaic components discovered in western North Carolina include a Savannah River component that
was excavated at Warren Wilson on the Swannanoa River in Buncombe County (Keel 1976). Several
Late Archaic occupations were identified during a survey of Watauga County, adjacent to the study
' corridor (Purrington 1975). In the North Carolina Piedmont such points became smaller over time. A
variety of scrapers, drills, grooved groundstone axes, hammerstones, netsinkers, polished atlatl weights,
and stone mortars was also common (Ward and Davis 1999:64). Subsistence data from the Late Archaic
' period are lacking from Piedmont sites; however, the location of base camps, such as Doerschuk,
Lowder's Ferry, and Gaston, with middens indicates a preference for living along major waterways. A
variety of animals, including fish, turtles, migratory birds, white-tailed deer, bear, and small mammals,
' would have existed in such an environment. Also, wild fruits, nuts, and berries would have been gathered
on a seasonal basis (Ward and Davis 1999:67).
' 3. Woodland Period (1000 BC to AD 1600)
a. Early Woodland and Middle Woodland Periods (1000 BC to AD 800)
' The overall settlement and subsistence pattern from the Late Archaic period changed very little during the
Early Woodland and Middle Woodland periods; however, there were a few significant innovations. Bow
and arrow technology completely replaced the use of the atlatl. In addition, evidence from the Forbush
' Creek Site (near Winston-Salem) and the Roanoke Rapids Reservoir sites (along the Roanoke River, in
the northern Piedmont) suggests that freshwater mollusks and other aquatic resources became an
increasingly significant part of the diet (Ward and Davis 1999:98). Village sites in the Piedmont are
' small, and suggest occupation either by small groups or of short duration (Sassaman et al. 1990:13). Early
12

Archaeological Survey Pott Creek R Stream Restoration Project, Catawba County, N. C.
' Woodland settlement is characterized by residential camps located in riverine environments. Limited-
activity camps were located in the adjacent upland zones.
' Ceramics took the place of soapstone vessels in cooking during this period. Specific ceramic varieties,
instead of projectile point styles, allow for the division of the Woodland period into subperiods.
Diagnostic ceramic series include Badin, Yadkin, Vincent, and Clement (Coe 1964; Davis 1996; Eastman
' and Lautzenheiser 1991). These series exhibit influence from the north and south but lack clear
association in terms of style and stratigraphic location. Badin or Yadkin wares are the earliest ceramic
series to appear; however, which of these two types came first varies from area to area, and they have
' sometimes been identified in contemporaneous layers (Ward and Davis 1999:97-98). Refinement in the
chronology for these four series, can only be made once radiocarbon dates have been obtained from intact
deposits or features.
' Pottery for the Early Woodland in the North Carolina Piedmont includes Badin and Yadkin wares; the
sequence was defined first at the Doershuk Site in the North Carolina Piedmont (Coe 1964; Davis 1996;
Eastman and Lautzenheiser 1991). These wares exhibit influence from the north and south but lack clear
' association in terms of style and stratigraphic location (Ward and Davis 1999:97-98). Badin sand-
tempered ware dates to 2400 to 2000 years before present (BP) at several sites in North Carolina and is
found in association with Badin triangular points (Blanton et al. 1986; Webb and Leigh 1995:28-29).
' Yadkin consists of cordmarked and fabric-marked varieties, as well as new surface treatments: check
stamping, linear check stamping, and simple stamping, which derive from Deptford wares of South
Carolina and Georgia (Ward and Davis 1999:83). Yadkin sherds are tempered with crushed quartz and
have been recovered in association with Yadkin triangular and Yadkin eared points (Blanton et al. 1986;
Coe 1964). Yadkin pottery has been dated to 2580 to 2170 BP in Sumter County, South Carolina
(Blanton et al. 1986:167).
' b. Late Woodland Period (AD 800 to 1600)
' Late Woodland groups in North Carolina followed different trajectories in their development. In some
areas an essentially Middle Woodland lifeway continued until the Mississippian period, while in other
portions of the state, Late Woodland groups developed complex social systems and agricultural
economies (Ward and Davis 1999). In some areas, Late Woodland cultures persisted to the time of
' European contact in the sixteenth through eighteenth centuries, and in others Late Woodland culture was
subsumed into the South Appalachian Mississippian tradition.
I Cultivation of domestic plants (especially corn and beans) is a hallmark of the Late Woodland period.
Concentration on agricultural pursuits brought about a great increase in the occupation of broad
floodplains. Population and village sizes grew because such locations could support more people. The
' complexity of settlements also grew, and more villages were protected by palisades (Ward and Davis
1999:4).
' Several Late Woodland phases that are part of the Piedmont Village tradition, based on diagnostic
ceramic wares, have been identified in the Piedmont of North Carolina (Ward and Davis 1999). All of
these groups were located to the north and east of the study corridor. These include the Uwharrie phase
(1150 to 750 BP), the Haw River phase (950 to 550 BP), the Dan River phase (950 to 500 BP), the
' Donnaha Phase (950 to 500 BP), the Hillsboro phase (550 to 350 BP), and the Early Saratown phase (500
to 350 BP) (Ward and Davis 1999). These phases appear to be the remains of Siouan-speaking groups
ancestral to the tribal groups encountered by European explorers, and reflect even greater regionalization
' within physiographic provinces. For example, the Dan River and Saratown phases of the central and
northern Piedmont may represent the remains of "peoples ancestral to the Sara Indians," while the
Hillsboro phase of the north-central Piedmont may be related to the "Eno, Shakori; and Occaneechi
' tribes" (Ward and Davis 1999:99).

In the southern Piedmont the Pee Dee culture was identified first at the Town Creek Site in Montgomery
County, North Carolina. The Pee Dee occupation is represented by a palisaded village that included a
habitation area, a central plaza, and a temple mound (Ward and Davis 1999:123-125). A total of 563
burials were excavated at the site. Pee Dee components have been identified at village sites and show that
the Pee Dee culture covers a much larger period than that evidenced by the Town Creek Site. A
significant change from earlier periods was the introduction of maize agriculture, which was the most
important component of the diet of the inhabitants at the Leak Site. Subsistence was supplemented by
more traditional natural resources (Ward and Davis 1999:131-132). Pottery consists of bowls and jars
with complicated stamped surfaces as well as vessels decorated with the filfot-cross design (Ward and
Davis 1999:126). Judging from the pottery and the character of the village/mound complex, it appears
that Pee Dee culture is a localized manifestation of the Southern Appalachian Mississippi Tradition.
4. Mississippian Period (AD 1000 to 1450)
Complex, chiefdom-level societies developed in the southeastern United States during the Mississippian
period. This period is characterized by large village sites located on floodplains, as well as by earthen
mounds, settlement hierarchy, evidence of social stratification, and an economy based on agriculture. In
addition to these extensive sites, there are low-density sites that represent specialized procurement or
hunting locations. Hallmarks of Mississippian sites include ceramic types that are distinguished on the
basis of elaborate decorative motifs and rim treatments. These complicated-stamped ceramics contrast
with the plain, cordmarked, fabric-impressed, and simple-stamped ceramics that characterize the
preceding Woodland period (Anderson 1989). Anderson (1989:115) notes that in addition to signaling
Mississippian occupations, the rim treatment of Mississippian pots constitutes a sensitive chronological
attribute. He points to a progression of unmodified to collared rims, to rims with rosettes or punctations,
and finally to applied-and-pinched rim strips. This sequence prevails through most of the region.
West of the study corridor the South Appalachian Mississippian tradition is the regional manifestation of
Mississippian societies. South Appalachian Mississippian sites have been identified as far north as Lee
County, Virginia, as far west as Knox County, Tennessee, as far south as Oconee County, South Carolina,
and as far east as McDowell County, North Carolina (Dickens 1976:16). In the Appalachian Summit,
Mississippian sites range from small farmsteads to large palisaded villages, often with small sites located
in the vicinity of villages with mounds (Ward and Davis 1999). The villages, surrounded by palisades,
were located "along major streams and in the tributary valleys, on or adjacent to fertile bottomland soils"
with houses in a circular or oval pattern around a central plaza (Dickens 1976:94-96). Mississippian
economies focused on deer, maize, beans, squash, sumpweed, acorns, hickory nut, walnut, and butternut
(Ward and Davis 1999:171).
A distinctive pottery tradition based on the Lamar style horizon developed in the Catawba River valley
during the Mississippian period (Moore 2002:162). Sand and soapstone tempered wares characterized by
complicated stamped, burnished, and plain exterior surface treatments share technological and stylistic
similarities with the Lamar-Pee Dee ceramics to the south and Qualla ceramics to the west (Moore
2002:161). In the Middle Catawba River valley the Cowans Ford pottery series includes sand and fine
quartz tempered sherds with plain, burnished, complicated stamped, and corn cob impressed exterior
surfaces (Moore 2002:132). The Cowans Ford series is associated with the Mississippian Low phase (AD
1400 to 1600) and the Contact period Iredell phase (AD 1600 to 1725). Sites dating to the Iredell phase
have ceramic assemblages characterized by Cowans Ford complicated stamped pottery with large motifs.
Rims are typically folded and punctuated (Moore 2002:182). Sites with components dating to the Low
and Iredell phases may have limited numbers of European trade goods indicative of early contact with the
Spanish expeditions of Juan Pardo and later contact with North Carolina and Virginia traders (Hudson
1990; Moore 2002). It appears likely that the burnished wares of the Historic period Catawba Indians are
stylistically similar and probably related to the Lamar-like ceramics of the Low and Iredell phases.

B. HISTORICAL OVERVIEW
Colonial Period (1540 to 1781)
I
F
Although Spanish explorations of western North Carolina are known to have occurred during the mid-
sixteenth century, the area of present-day Catawba County was not occupied by European-American
settlers until around 1750. Prior to that time western North Carolina was known by traders and explorers,
who often used native trade routes, but because of hostilities with native inhabitants (Siouan-speaking
Catawba), few immigrants risked permanent settlement in the area. As coastal populations increased,
trade with Native Americans also increased; however, trade contact also resulted in the introduction of
disease, which decimated the native populations and brought about the abandonment of many of their old
settlements (Davis 1999:5; Smith 1997:13). This out-migration made way for European settlement in the
Appalachian foothills during the early eighteenth century. In 1750 Anson County was established and
included all of the Piedmont in western North Carolina (including present-day Catawba County), from the
Virginia line to the north, to the South Carolina line to the south, and to the Mississippi River in the west
(Corbitt 1987[1950]:8-10). In 1753 Anson was divided and the northern part became Rowan County.
As a result of the failure of the Native American uprising in the Yamassee War, the Catawba Nation was
formed in the eighteenth century from several groups that once formed the Cofitachique confederation
(Harris 1987:2). These groups were encouraged to settle there by the colonial government to serve as a
buffer at northern border of the colony, and included the Kadapaus, Esaws, Sugarees, Waterees, Wisacks,
Congarees, Santees, Saponis, Cussoes, Peedees, Yamassees, Coosas, Enos, Occaneechis, Keyauwees,
Chowans, Nachees, and Cheraws. Although the groups maintained separate identities, they were bound
by trade, marriage, and adoption. In 1759 a smallpox epidemic killed over 50 percent of the Catawba. As
a result, groups left the Sugar Creek villages and settled at Pine Tree Hill (later, Camden, South Carolina)
and then moved to the upper Catawba at 12 Mile Creek (Harris 1987:3). The villages at 12 Mile Creek
were destroyed by the British during the Revolutionary War, so the remaining groups then moved to lands
that had been given to them by treaty in 1763. It was during the eighteenth century that the pottery trade
developed among the Catawba (Harris 1987:4).
The last half of the eighteenth century was a period of immigration into western North Carolina. Most of
the settlers were drawn by cheap and abundant farmland that was rich in natural resources. Early land
claims generally took place along the major waterways, including the Broad, Catawba, and Yadkin rivers.
Records show that Adam Sherrill and his family settled on the west bank of the Catawba River in what is
now Catawba County in 1747 (Halma 1991:11). In addition to the Sherrill family, Johann Heinrich
Weidner, a German immigrant, received a land grant of 1,240 acres near the South Fork of the Catawba
River in 1750. The early Scots-Irish settlers became established in the eastern portion of the county while
many of the county's first German settlers took up residence in the south central part of present-day
Catawba County (Halms 1991:11).
The Cherokee War (1760 to 1761), fought in the southern Appalachians, was part of the French and
Indian War (1754 to 1763), in which the British and French battled over claims to western lands.
Cherokee villages were attacked by British forces in retaliation for native attacks on small British
settlements. A new boundary along the Blue Ridge Mountains in western North Carolina pushed the
Cherokee further west, and white settlement beyond the boundary was prohibited. Treaties signed after
the French and Indian War, including the Treaty of Paris in 1763, and after the Revolutionary War
reduced Cherokee holdings even further.
' 2. National Period-Antebellum Period (1781 to 1834)
Immigration into the western region of the state continued during the remainder of the eighteenth century
' and into the first half of the nineteenth century. Several settlements had been established in the foothills
15
Archaeological Sun?ey Pott Creek 11 Stream Restoration Project, Catawba County, N.C.
of the Blue Ridge by the 1770s, and as the western region's population slowly increased, new counties
were formed. In the late 1770s Burke, Lincoln, Rutherford, and Wilkes were formed in the western part
of North Carolina (Corbitt 1987[1950]:42, 137, 188, 227). The early settlers in the area of present-day
Catawba County participated in subsistence-level farming and traded any over-production. Associated
industries, such as gristmills, sawmills, and tanneries, also developed as the population increased and
demand grew.
Catawba County was formed from a part of Lincoln County in 1842 (Corbitt 1987[19501:60). At the time
of its creation, the area of Catawba County was already populated by Scots-Irish and German settlers,
who had migrated south from Pennsylvania, as well as English Quakers. In the late 1700s Baptists and
Methodists from Maryland, Virginia, and eastern North Carolina had also moved into the northern part of
what was to become Catawba County.
3. Civil War (1861 to 1865)
North Carolina seceded from the United States on April 15, 1861, allying itself with the Confederate
forces during the Civil War (1861 to 1865). Although the vote had been far from unanimous, it was
generally endorsed by the citizens once the decision had been made (Powell 1989). During the war men
from Catawba County volunteered to serve in the Confederate Army and fought in such major battles as
Chancellorsville, Gettysburg, the Battle of the Wilderness, and Spotsylvania Courthouse. During the
latter days of the conflict, however, some residents of western North Carolina became disillusioned with
the Southern cause. "Bushwackers," or deserters from the Confederate Army, found refuge in the
mountains of western North Carolina. Although little significant fighting occurred in the vicinity of the
study corridor, Union forces plundered many areas as they swept through the region during the last weeks
of the war in May 1865. Wilkes, Watauga, and Alexander counties were all targets of the Union cavalry
ambush known as "Stoneman's Raid" (Barrett 1987:97).
4. Reconstruction to Twentieth Century (1865 to Present)
After the war agriculture continued to dominate the local economy. Between 1860 and 1900 the average
size of farms decreased while the number of farms increased, but the general economy of the South had
been devastated by the effects of war and it would be several decades before it regained its prewar volume
(Powell 1989:417). Catawba County farms, which had not been totally reliant on slave labor for
operation, recovered more quickly than farms in other, more slave-dependent parts of the state.
With regard to industry, both grist- and sawmills, located on larger rivers as well as along secondary
streams, dot the maps of the study corridor vicinity from this period. Smaller industries, such as
tanneries, potteries, and flour mills, were also in operation. In the western Piedmont of North Carolina,
mining of such native minerals as mica, feldspar, and kaolin was also underway by the early nineteenth
century. Other mines produced iron ore, plentiful in Lincoln and Gaston counties, and gold, silver, and
copper, found in Burke, Lincoln, and Mecklenburg counties, and boosted local economies. In 1816 the
first cotton mill south of the Potomac River was constructed in Lincoln County, North Carolina, which
was also the site of profitable ironworks and small gold deposits that were mined out before the middle of
the nineteenth century (Powell 1989:314). The first cotton mill in Catawba County began operation at
Long Island in 1839 (Preslar 1954:485). It was joined by a second mill in 1867. By 1884 mills were
operating in the communities of Monbo, Long Inland, Maiden, and Newton (Preslar 1954:485).
Catawba County remains predominantly rural, distinguished by small towns and rural settlements, such as
Hickory (the largest population center), Newton, Long Island, Maiden, and Plateau. Most farms, which
average about 100 acres, are operated on a part-time basis; major products include poultry, milk, apples,
beef, grain, wood products, and tobacco (Preslar 1954:491). The diverse economy of the county is still
dominated by agriculture, but furniture and textile manufacturing are also important enterprises. The
16

Archaeological Survey Pott Creek II Stream Restoration Project, Catawba County, N.C.
' county also benefits from its proximity to Lake Hickory, which was created between 1927 and 1928 with
the construction of the Southern Power Company's (later the Duke Power Company) 91-foot-high
concrete Oxford Dam and Hydroelectric Plant on the Catawba River 9 miles south of Taylorsville (Bishir
et al. 1999:138). During the early 1960s this company impounded the Catawba to form Lake Norman
behind its new Cowans Ford Dam, which is situated south of Iredell in Mecklenburg County. As a result
of the lakes created by these two hydroelectric projects, summer resorts and fishermen's cabins were
' constructed (Bishir et al. 1999:138), adding tourism to Catawba County's economy.

IV. RESULTS OF BACKGROUND RESEARCH
I A. INTRODUCTION

J

1

Research was carried out in the site files and survey reports at the OSA and the North Carolina SHPO to
assess the Pott Creek study corridor's potential to contain archaeological resources. Additional research
was conducted at the North Carolina State Archives and the North Carolina State Library, the North
Carolina Geological Survey, and the North Carolina Division of Soil and Water Conservation. The
objective of the background research was to gather information to characterize the cultural resource
potential of the study corridor vicinity and develop cultural contexts (see previous chapter) for evaluating
any archaeological resources that might be located in the study corridor.
B. ARCHAEOLOGICAL RESOURCES
To determine the survey area's potential for prehistoric cultural resources, Berger reviewed
archaeological site inventory data at the OSA. In addition, Berger reviewed survey reports that discuss
prehistoric settlement in the vicinity of the study corridor. Information from these sources can be used to
characterize the locational attributes of prehistoric sites and site types in the region.
A review of the archaeological site inventory showed no previously recorded prehistoric sites within a 2-
mile (3.2-kilometer) radius of Pott and Rhodes Mill creeks. Although there are no recorded sites in the
immediate vicinity of study corridor, several important sites with late prehistoric components were
identified as part of the Cowans Ford Reservoir Survey conducted during the early 1960s (Moore
2002:127-131). These sites (31CT8, 31CT10, 31CT30, and 31CT96) are located on well-drained
elevated land surfaces overlooking the floodplain of the Catawba River and its tributaries approximately
20 miles (32 kilometers) east of the study corridor. In addition, elevated land forms similar to those
found along the tributaries of the Catawba River appeared to exist adjacent to Pott and Rhodes Mill
creeks. For these reasons, it was considered likely that prehistoric archaeological sites existed within the
study corridor.
C. HISTORIC CULTURAL RESOURCES
A review of archaeological site inventory files showed that no previously recorded historic archaeological
sites are located within a 2-mile (3.2-kilometer) radius of the study corridor. The probability of finding
historic cultural resources within the study corridor was considered to be low.

V. METHODS AND TECHNIQUES
The archaeological survey of the study corridor within the Pott Creek project entailed surface
reconnaissance and subsurface testing. Surface reconnaissance was conducted to identify archaeological
sites within the study corridor and to eliminate portions of the study corridor from further consideration
on the basis of disturbance, excessive slope, or other factors. The reconnaissance involved the inspection
of the study corridor in order to locate areas with good surface visibility, such as cutbanks, exposed
ground surfaces, and erosional features, in order to identify structural remains, cultural deposits, and any
other cultural features. This task was carried out by a pedestrian survey of the perimeter of the study
corridor, including all fence and ditch lines, creek banks, and other exposed land surfaces.
Subsurface testing consisted of the excavation of shovel tests, and auger tests. The shovel tests measured
approximately 12 inches (30 centimeters) in diameter and were placed at 100-foot (30-meter) intervals
along transects spaced 100 feet (30 meters) apart. The transects were identified by letter. Along each
transect, shovel tests were numbered according to their order in sequence from the baseline or starting
location. Each shovel test was assigned an identifier using the combination of the transect letter and the
shovel test number (A-1, B-4, etc.). Shovel tests were excavated by natural strata into culturally sterile
subsoil. All excavated soil for the shovel tests was screened through 0.25-inch (6-millimeter) hardware
cloth for systematic recovery of artifacts.
The potential for buried Holocene deposits containing archaeological resources was investigated by measurin 3 inches (7.6 excavating atthe a series of auger bottom of foure of,the shovel tests (A 2, A-4, D-28, and D-30) and were continued inwere to
started
culturally sterile subsoil.
For all excavations, the profile, soil texture, and soil color according to Munsell soil color charts were
recorded on Berger's standardized forms. Information on environmental and cultural conditions (e.g.,
natural slopes, structures) in the study corridor area was detailed in a field book. No archaeological
resources were identified within the study corridor, and therefore no natural or archaeological resources
were recorded using a Trimble Pro XRS GPS Receiver. Color photographs were taken of the study
corridor. All shovel tests, auger tests, and test units were backfilled upon completion of the fieldwork.
No artifacts were recovered from the archaeological investigation, so no laboratory analysis was
conducted at Berger's laboratory facility.

VI. RESULTS OF ARCHAEOLOGICAL FIELD INVESTIGATIONS
A. INTRODUCTION
The study corridor is bounded by the main channels of Pott and Rhodes Mill creeks to the east and south
' (see Figure 2). In general, the western boundary of the study corridor was 100 feet (30 meters) from the
main channels of Pott and Rhodes Mill creeks, and its northern border was formed by the woods line.
Pott Creek flows down the center of the stream restoration area, and Rhodes Mill Creek forms its southern
boundary (see Figure 2).
The study corridor traverses pastureland, the stream banks of Pott and Rhodes Mill creeks, a minor
amount of steeply sloping terrain, existing wetlands, and disturbed areas (see Plates 1-5). Ground surface
visibility was poor within the corridor because of the ground cover (see Plates 1 and 2). Berger excavated
a total of 83 shovel tests and four auger tests along five transects (A-E) within the study corridor.
B. SURFACE RECONNAISSANCE

Berger conducted a surface reconnaissance of the tract on March 29, 2004. The reconnaissance provided
data for modifying expectations relative to archaeological site potential. No slopes greater than 15
percent were observed. Minor amounts of sloping terrain were encountered along the western boundary
of Pott Creek (see Plate 3). Wet areas adjacent to Pott Creek were identified during the reconnaissance
(see Plate 4). Portions of the Pott Creek floodplain in the vicinity of Shovel Test Transects D and E had
been recently cleared and disturbed (see Plate 5). The main channels of Pott and Rhodes Mill creeks were
excluded from subsurface testing. In general, ground surface visibility was less than 10 percent.
C. SUBSURFACE TESTING
Generally, the soils within the floodplain of Pott and Rhodes Mill creeks (Shovel Test Transects A, B, C,
D, and E) belong to the Chewacla and Congaree series (Brewer 1975). Transects A and D were laid out
on the west side of Pott Creek approximately 50 feet (15 meters) from the edge of the creek. Transects B
and C were laid out on the north side of Rhodes Mill Creek approximately 50 feet (15 meters) and 100
feet (30 meters) from the edge of the creek. Transect E extended along a small unnamed tributary of Pott
Creek for a distance of approximately 200 feet (60 meters). Minor exceptions to this drained surface depressions.gA total of 83
occurred when shovel tests were off-set to avoid small, poorly shovel tests were excavated along these five transects.
In general, the soil profiles exposed in the shovel tests and auger tests excavated on Shovel Test Transects
A, D, and E exhibited the following stratigraphy (based on Shovel Test D-30): Stratum A, a yellowish
brown (10YR 5/4) silt loam from 0 to 3 inches (0 to 8 centimeters) below ground surface (bgs); Stratum
B, a strong brown (7.5YR 5/6) silt loam from 3 to 14 inches (8 to 36 centimeters) bgs; Stratum Stratum CD, a

recent ground disturbance along these two transects.
t No artifacts, buried cultural deposits, or cultural features were identified in any of the 83 shovel tests
excavated in the Pott Creek study corridor. No buildings, structures, or important vernacular landscape
features are present. It is likely that this floodplain was cleared of a hardwood floodplain forest natural
' community early in the nineteenth century. In general, the relief within the study corridor consists of a
uniform floodplain with few elevated, well-drained land surfaces. These sediments showed evidence of
disturbance, probably from a combination of timber harvesting and stream bed canalization. Evidence of
t recent land clearing activities included several large piles of discarded timber.

I VII. SUMMARY AND EVALUATIONS
Berger has completed an archaeological survey for EarthMark, LCC, in association with the proposed
Pott Creek H Stream Restoration Project (TIP No.: R-999WM; State Project No.: 8.1777741), Catawba
County, North Carolina. As part of a transportation-related project, approximately 8,200 linear feet
(2,499 meters) of existing stream and adjacent wetland areas along Pott and Rhodes Mill creeks will be
restored for the purposes of mitigation. The archaeological survey was limited to the areas that will be
disturbed by the stream restoration. These areas were defined by EarthMark as the study corridor (see
' Figure 1); the corridor's total area was approximately 20 acres (8 hectares).
The objective of this survey was to identify any archaeological resources within the study corridor, and
' archaeological sites that did not contain intact deposits were to be evaluated for inclusion in the National
Register of Historic Places. Field investigations were initiated with surface reconnaissance to determine
the medium- to high-potential areas within the study corridor. In addition to surface reconnaissance,
' Berger used systematic shovel tests, and auger tests to determine if any artifacts, intact cultural remains,
or archaeological sites could be identified within the study corridor. Shovel Test Transects A and D were
laid out on the west side of Pott Creek approximately 50 feet (15 meters) from the edge of the creek.
Transects B and C were laid out on the north side of Rhodes Mill Creek approximately 50 feet and 100
' feet (30 meters) from the edge of the creek. Transect E extended along a small unnamed tributary of Pott
Creek for a distance of approximately 200 feet (60 meters). Minor exceptions to this generalization
occurred when shovel tests were off-set to avoid small, poorly drained surface depressions. A total of 83
' shovel tests and four auger tests were excavated along these four transects.
In general, the relief within the study corridor consists of a uniform floodplain with few elevated, well-
drained land surfaces. These sediments showed evidence of disturbance, probably from a combination of
timber harvesting and stream bed canalization. It is likely that this floodplain was originally cleared of a
hardwood floodplain forest natural community early in the nineteenth century. Evidence of recent land
clearing activities included several large piles of discarded timber. These factors substantially reduced
the probability of identifying prehistoric archaeological sites within the study corridor. No buildings or
structures are present.
' No artifacts, buried cultural deposits, or cultural features were identified in any of the 83 shovel tests and
four auger tests excavated within the study corridor. It is Berger's recommendation that no further
archaeological investigations of the Pott Creek project are warranted.

Re: - Pott Creek II Mitigation Site, Stream Restoration, Catawba County, ER04-0672
Dear Mr. Mogensen:
Thank you for your letter of April 14, 2004, transmitting the archaeological management
summary, concerning the above project.
The letter and management summary state that no archaeological sites were discovered in the
proposed project area. A total of 82 shovel tests were excavated. We concur with the
recommendation that no additional archaeological work is needed. Since no sites were found
there is no need for a great deal of background. A short report with a map will be adequate.
On April 26, 2004, a staff archaeologist left a voice mail message for Mr. Lee Tippett to this
effect.
The above comments are made pursuant to Section 106 of the National Historic Preservation
' Act and the Advisory Council on Historic Preservation's Regulations for Compliance with
Section 106 codified at 36 CFR Part 800.

Thank you for your cooperation and consideration. If you have questions concerning the
above comment, please contact Renee Gledhill-Earley, environmental review coordinator, at
919/733-4763. In all future communication concerning this project, please cite the above-
referenced tracking number.

Dear Mr. Barrett:
Subject: Pott Creek II Mitigation Site, Catawba County, North.Carolina
You requested our review of the subject site, which is proposed as potential wetland mitigation
in Catawba County, North Carolina. Specifically, you requested verification that no listed
species or their critical habitat would be impacted by this project. No information was provided
regarding any proposed activities for this site; therefore, our comments are primarily focused on
listed species that may be found on the site. We request the opportunity to review future plans
and provide more specific comments as more information becomes available about the site and
its suitability for restoration. The following comments are provided in accordance with the Fish
and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and section 7 of the
Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
Enclosed is a list of species from Catawba County that are on the Federal List of Endangered
and Threatened Wildlife and Plants. Although our records for Catawba County indicate no
known locations of listed species in the immediate project area, there are several occurrences of
the federally threatened dwarf-flowered heartleaf (Hexastylis nanaflora) in the vicinity. The Pott
Creek II site should be assessed and surveyed for protected species prior to any further planning
or on-the-ground activities to ensure that no adverse impacts occur. If listed species are found on
the site, further consultation will be required.

We appreciate the opportunity to provide these comments. If you have any questions or
concerns, please contact Ms. Marella Buncick of our staff at 828/258-3939, Ext. 237. In any
future correspondence concerning this project, please reference our log number 4-2-04-161.
Sincerely,
Brian P. Cole

ENDANGERED, THREATENED, AND CANDIDATE SPECIES AND FEDERAL
SPECIES OF CONCERN, CATAWBA COUNTY, NORTH CAROLINA
This list was adapted from the North Carolina Natural Heritage Program's County Species List. It is a
' listing, for Catawba County, of North Carolina's federally listed and proposed endangered, threatened,
and candidate species and Federal species of concern (for a complete list of rare species in the state,
please contact the North Carolina Natural Heritage Program). The information in this list is compiled
from a variety of sources, including field surveys, museums and herbaria, literature, and personal
communications. The North Carolina Natural Heritage Program's database is dynamic, with new records
being added and old records being revised as new information is received. Please note that this list
cannot be considered a definitive record of listed species and Federal species of concern, and it should
not be considered a substitute for field surveys.
' Critical habitat: Critical habitat is noted, with a description, for the counties where it is designated or
proposed.
Aquatic species: Fishes and aquatic invertebrates are noted for counties where they are known to occur.
' However, projects may have effects on downstream aquatic systems in adjacent
counties.

Subject: Pott Creek II Mitigation Site - Stream Restoration Project; Catawba County
Dear Mr. Barrett:
The Natural Heritage Program has a record of the State Significantly Rare Santee chub
(Cyprinella zanema) from Pott Creek at the SR 1217 bridge, just below the project area. It can
be assumed to occur in the project site. Though our Program agrees with your letter dated March
12, 2004 that "no known federal or state protected species or their critical habitat are within 1.0
mile of this stream restoration project", based on a review of our Program's maps, we feel
obligated to mention the presence of this rare, though not State-protected, fish species. If at all
possible, stream impacts such as sedimentation should be avoided or minimized during
construction of the project.
Although our maps do not show records of other natural heritage elements in the project area, it
does not necessarily mean that they are not present. It may simply mean that the area has not
been surveyed. The use of Natural Heritage Program data should not be substituted for actual
field surveys, particularly if the project area contains suitable habitat for rare species, significant
natural communities, or priority natural areas.
You may wish to check the Natural Heritage Program database website at
<www.ncsl2arks.net/nhp/search.html> for a listing of rare plants and animals and significant
natural communities in the county and on the topographic quad map. Please do not hesitate to
contact me at 919-715-8697 if you have questions or need further information.

control plan.
Install rain gage on site.
Contact local Soil Erosion Authority for on-site inspection by
Environmental Inspector and obtain certificate of compliance.
Begin clearing, maintain devices as needed.
Begin channel construction, stockpile waste material in designated spoil
areas and surround with silt fencing.
Ground cover must be done for any exposed slopes, including spoil piles,
within 15 working days or 30 calendar days of completion of any phase
grading, whichever comes first. Stabilize site as areas are brought to final
grade with vegetation.
When construction is complete and all areas are stabilized completely, call
for inspection by Environmental Inspector.
If site is approved, remove temporary stream crossing, silt fencing, access
roads, etc. and seed out any resulting bare areas.
When vegetation has become established, call for final site inspection by
Environmental Inspector.

PLANTING GUIDELINES
Bare Root Seedlings or Containerized Vegetation
Plant Selection
• Species listed for the project should be grown from stock that corresponds
to the same physiographic province in which they will be used.
¦ The on-site engineer reserves the right to reject any plant stock due to
inferior qualities.
Planting & Handling
• Bare root seedlings and containerized plant stock will be planted
according to vegetation details or as directed by the on-site engineer.
¦ on-site during the planting process unless proper refrigeration is provided
by the planting contractor.
Live Staking
Plant Selection
¦ All plant species used for live staking should conform to the specifications
set forth in the vegetation details.
• Plant species listed for use as live stakes will be selected from plants
found on the project site or as directed by the on-site engineer.
• Plant species used as live stakes will be collected during the dormant
season (December to March) and during normal average daily
temperatures for this period.
Preparation & Handling
¦ Plant species will be collected to conform to sizes specified in the
vegetation details.
¦ Live stakes will be prepared by making a straight cut at the narrow end of
the plant material forming a blunt end. The thicker end (toward the trunk)
of the plant will be formed into a point.
¦ Live stake preparation will be done according to vegetation details unless
otherwise specified by the on-site engineer.
Planting
¦ Live stakes should be prepared and planted immediately following
collection. Proper storage techniques should be followed to ensure the
highest rate of survival.
¦ Live stakes will be planted with the point of the live stake going into the
soil and the blunt end facing up.
• Live stakes will be placed as deep as possible and as close to the water
table as possible.
Storage
¦ Live stakes will be bundled and stored completely submerged in the
stream channel in the event immediate staking is not permissible.
Temporary storage will not exceed a one week period.
• Long term storage is not recommended due to the large numbers of live
stakes available on-site.
Transplant Vegetation
Selection & Handling
¦ Transplant. vegetation will be selected and flagged by the on-site engineer
for use on the project site. The on-site engineer reserves the right to
select any vegetation for transplant during any point of the project.
¦ All vegetation will be planted during the dormant season (December to
March). Temperatures ranging from 36 to 60 degrees Fahrenheit are
ideal for planting. Planting will not take place during periods exceeding
this range of temperature. Planting will not take place during excessively
windy conditions or other extreme conditions which may reduce vigor of
the planting material.
¦ The on-site engineer reserves the right to reject any bare root seedling or
containerized plant due to inferior quality. The on-site engineer also
reserves the right to have any plant replanted due to improper planting
techniques.
¦ All vegetation designated for a particular planting zone will be culled for
inferior quality before being loaded into planting bags. Furthermore, these
species will be thoroughly mixed prior to loading the planting bag, such
that each planting zone will be planted in a random manner.
¦ All vegetation will be reviewed by the on-site engineer to ensure the
highest quality of planting material throughout the entire process.
Storage
• Plant stock will be stored at temperatures between 36 to 40 degrees
Fahrenheit in appropriate bags supplied by the plant producer when long-
term storage is necessary.
¦ Only the necessary quantities of plant stock will be transported to the site
on a daily basis. Large quantities of planting material will not be stored
¦ Live staking will be done according to the vegetation details unless
otherwise specified by the on-site engineer. The on-site engineer
reserves the right to reject any live stake due to inferior quality. Likewise,
any improperly planted live stake will be corrected by the planting
contractor.
Transplant vegetation will be planted within 1 day of being moved from its
original location. If planting in desired location is not feasible, the
transplant will be replanted or stored in a manner as to ensure its long-
term survival. The on-site engineer will provide guidance throughout the
process.
