Bertie County, North Carolina-May, 2009
• 1.0 EXECUTIVE SUMMARY
This report is submitted by Albemarle Restorations, LLC (AR) to document the
completion of the restoration of 48.4 acres of riverine wetlands and 3,310 linear feet of
stream (swamp run restoration) on the Powell Property located on Meadow Road near
Buzzards Crossroads, Bertie County, North Carolina.
Prior to restoration, the easement area was used entirely for agriculture production,
primarily corn, soybeans and cotton. The existing farm fields were drained by several
drainage ditches that traverse the site and outfall into Quioccosin Swamp. No natural
plant communities of any biological value were found within the project area, and all
ditches were actively maintained to remove vegetation and debris.
The goal of the project was to restore a diverse riparian headwater "swamp run" system
and its associated riverine wetlands to provide the following ecological benefits:
1) Water quality improvements, including nutrient, toxicant and sediment retention
and reduction, increasing dissolved oxygen levels, reducing excessive algae
growth, and reducing surface water temperatures in receiving waters by providing
permanent shading in the form of a shrub/scrub and forested headwater wetland
system.
2) Wildlife habitat enhancement by adding to the existing adjacent forested areas to
create a continuous travel corridor between habitat blocks and provide a wide
• range of habitat areas (open water, emergent, shrub/scrub and forested) for
amphibians, reptiles, birds, insects and mammals.
3) Flood flow attenuation during storm events, to help which reduce sedimentation
and erosion downstream, and improve long term water quality within the Chowan
River.
4) Passive outdoor recreation and educational opportunities.
In order to achieve these goals, restoration activities, in accordance with the approved
Restoration Plan, began June 30, 2008 and were completed on January 29, 2009.
Restoration consisted of grading the headwater riverine complex at varying elevations to
create microtopography and braided channels that emulated natural "swamp run" systems
found within the Chowan River Basin. The surrounding riverine wetlands were restored
by grading the existing farmland to create wide floodplains and seasonally saturated
wetlands. Native trees and shrubs were planted on site during January 27, 28, and 29,
2009, to restore habitat and create a species diverse wetland system. Additionally, an
emergent wetland seed mixture was applied concurrent with the finish grading to provide
immediate habitat and water quality benefits. All planting and grading was conducted in
accordance with the approved restoration plan.
Ten permanent water level monitoring gauges were installed on January 29, 2008 at
random and varying locations and elevations throughout the riverine wetland portions of
the site to measure subsurface water elevations. Additionally, two monitoring gauges
• were installed at a reference wetland site. Locations of all installed and proposed
monitoring devices and vegetative plots are shown on Sheet M-1 in Appendix B. Ten

• vegetative monitoring plots have been permanently monumented. Each plot is a 10m X
10m square, as recommended by the CVS-EEP Protocol for recording vegetation. These
quadrants will be monitored for a minimum five-year period, or until success of the
project can be validated.
Monitoring Reports will be submitted to the North Carolina Ecosystem Enhancement
Program (EEP) by December 31 of the year in which the monitoring was conducted.
The reports will include all water elevation data and CVS-EEP Protocol vegetation data.
The monitoring gauges will be checked four times per year, at which time a visual
assessment of inundated areas will be made. The targeted plant community is a swamp
run and riverine wetland mosaic. The site will be deemed successful if the acreages of
each regime falls within a reasonable range related to the design during normal climatic
conditions. Site hydrology during years of excessive rainfall or extreme drought will be
assessed with climatic conditions in mind and will be compared with data collected at the
reference wetland site.

2.0 AS-BUILT REPORT
2.1 Project Background
The Powell Property, located on Meadow Road (State Road 42) near Buzzards
Crossroads, Bertie County, North Carolina was chosen in part because of its location in a
targeted watershed and because it provides the opportunity to add contiguous diverse
wetland habitat to a high quality forested wetland system directly adjacent to the project
area. On July 3, 2006, AR entered into a contract with EEP for the procurement of 70
riverine wetland mitigation units (WMU's) and 3,310 stream mitigation units (SMU's) on
the Powell Property. The number of acres proposed for wetland restoration was later
reduced to 48.4 (48.4 WMU's) based upon the Army Corps of Engineers request that
restoration only be performed on acreage with strong hydric soil characteristics.
Restoration of the site occurred during the fall of 2008. Table 2 below summarizes the
project history.

2.2 Pre-existing Site Conditions
The overall Powell property consists of approximately 378 +/- acres, 56 of which are
designated for this project site. The project is located on the eastern portion of the farm
and has a total drainage area of approximately 871 acres. The site was previously
bisected by a large drainage ditch that runs south to north and forms the headwaters of
Quioccosin Swamp. There were also several small ditches and drainage tiles that
intersected the project area contributing flow to the main ditch. The stream restoration
component of the project involved restoring the main drainage ditch and portions of two
smaller ditches to a headwater swamp run. The majority of the project area is bordered
by agricultural fields to the east and west, with timberland to the south and Quioccosin
Swamp to the north. Degradation to the channels and surrounding areas by past
agricultural activities, including channel straightening and planting of row crops up to the
• channel edges, has allowed excessive nutrient and sediment accumulation in the channels
and downstream receiving waters. These past activities have also served to dramatically
reduce the flood flow attenuation capabilities of the channels. Appendix A contains
photographs taken during a pre-construction site visit, showing the degradation of the
channel and the proximity of tilled ground.
2.3 Construction and Planting
Restoration activities, in accordance with the approved Restoration Plan, began on June
27, 2008 with the installation of recommended erosion control practices and grading of
the headwater swamp run system. After the swamp run (stream) portion of the project
was completed, the adjacent riverine wetlands were graded. Topsoil, which had been
stockpiled during initial construction, was redistributed during final grading. Lastly, the
wide, gently sloping outlet was completed. Additionally, at EEP's request, changes in the
original design were made at the confluence of the two swamp runs (see sheets D-2 & D-
3).On January 15, 2009 all grading operations were completed. The As- Built survey for
the grading is included in Appendix B, sheets G-2 thru G-3.
Tree and shrub planting on the project site was completed on January 28 and 29, 2009
using bare-root seedlings and live stakes (live stakes were used for the black willows,
Salix nigra). The emergent wetland seed mixture was spread just after grading was
completed. All planting was done in accordance with the approved restoration plan, the
• exception being the replacement of some species due to availability and planting spacing.
Additionally, the planting rate was increased to 601 stems per acre, as opposed to the 350

2.4 Post Construction Site Conditions
Within two months of project completion, the restored swamp run and adjacent riverine
wetlands had experienced "overbank" flooding. The swamp run has been inundated
during each periodic site visit since the project was completed. Photographs of the site
taken in May 2009 are found in Appendix A.
3.0 Monitoring Plan
Monitoring of the site is to be completed per EEP's guidelines titled Content, Format
and Data Requirements for EEP Monitoring Reports for a five year period, with
monitoring beginning in fall 2009 (Year 1) and concluding in 2013 (Year 5).
Photographs and/or video footage of major flow events, to the extent that is possible, will
be included in each year's monitoring report. Monitoring methods for the headwater
swamp run system will be in accordance with the "Information Regarding Stream
Restoration with Emphasis on the Coastal Plain" as outlined in 3.1 below, and
monitoring for the associated riverine wetlands will consist of vegetative and hydrology
monitoring as outlined in sections 3.2 and 3.3 below.
3.1 Headwater Swamp Run Monitoring
• 3.1.1 Swamp Run Hydrology Monitoring
Monitoring of the riparian headwater systems will focus on wetland hydrology,
vegetative survival, and precipitation-driven flow events. While the methods regarding
the monitoring of hydrology and vegetation are well established, flow documentation
within zero-order stream systems is the topic of on-going research throughout the Coastal
Plain. Both qualitative and quantitative information will be used to properly document
the occurrence of flow within the proposed restored zero-order stream valley.
Monitoring of the headwater swamp run system created on the site will be in accordance
with success criteria outlined in "Information Regarding Stream Restoration with
Emphasis on the Coastal Plain." According to the guidance, the monitoring of these
systems should be geared toward documenting restored functions rather than using
traditional geomorphic studies. Monitoring will consist of assessing groundwater
elevations in the swamp run, continuous water surface elevation documentation,
vegetation plot monitoring, and methods to assess flow patterns and duration of
inundation. If it is determined that surface water inundation and coverage, surface water
flow, and vegetation establishment are all within the attainment criteria set forth below,
the restoration of a functional headwater swamp run will be deemed successful.
Surface and sub-surface hydrology within the swamp run will be monitored and evidence
• of flow will be documented. To monitor both subsurface and surface water elevations,
three continuous recording pressure transducer type water level loggers suspended in
ALBEMARLE RESTORATIONS, LLC. 6
Powell Property Wetland and Stream As-Built Plan
Chowan, 03010203
Bertie County, North Carolina-May, 2009
is monitoring gauges have been installed within the limits the of the swamp run. The three
monitoring gauges have perforations in the PVC to allow water into gauge so the logger
can track surface water influences. These gauges are arranged so that they are at the
lowest point of the valley and form a perpendicular axis across the valley when used in
conjunction with the monitoring gauges in the riverine wetlands. Data from the gauges
will be downloaded from each monitoring station four times per year, and during each
site visit hand measurements will be taken and visual observation noted to ensure the
accuracy of the water level loggers. The lateral extent of inundation will also be
approximated at each site visit and recorded. In order to infer flow, data collected from
these gauges will be correlated with elevation data from the longitudinal profiles, the on
site rain gauge, and the offsite rain gauges in Murfreesboro and Edenton and presented in
graphical format.
Site visits will also be conducted following rain events to document the upstream extent
of observed flow within each reach. GPS data will be collected to mark this location.
During runoff/storm events, pictures and/or video will be recorded to the extent
practicable and provided in the annual monitoring reports in DVD format.
Qualitative data will be collected during the on-site investigations to document surface
water flow. This shall be accomplished using photographic evidence of observed flow
coupled with a preponderance of field indicators of recent flow events in the form:
• a natural line impressed on the bank,
• shelving,
• changes in soil characteristics,
• destruction of terrestrial vegetation,
• presence of litter and debris,
• wracking,
• vegetation matted down, bent or absent,
• sediment sorting,
• leaf litter disturbed or washed away,
• scour,
• deposition,
• bed and bank formation,
• water staining,
• and change in plant community.
All field indicators present will be documented in each monitoring report. All
quantitative and qualitative data will be used to document the upstream limit of flow,
which will provide the basis for length of successful zero order stream restoration (i.e.
valley length).
The primary success criteria for the Riparian Headwater/Zero Order Stream system will
be the documentation of 2 flow events using the techniques discussed above within a
• normal rainfall year in 3 of the 5 years of monitoring. Additional monitoring may be
necessary in the event of abnormal climatic conditions.

Bertie County, North Carolina -May, 2009
0 Precipitation Documentation:
Rainfall data will be collected on-site through an event rainfall logger. This gauge has
been placed directly adjacent to the project site, and will record rainfall intensity,
duration, time and quantity. Rainfall data from two other sites, one in Murfreesboro,
North Carolina, approximately 26 miles northwest of the project site and another in
Edenton, North Carolina, approximately 20 miles southeast of the site will be used as
references to determine the deviation from climatologically normal rainfall in the area.
The rainfall data will be assessed to determine the degree to which climatologic extremes
(i.e. drought or excessive rainfall) affect subsurface water levels, and surface water extent
and flow.
3.1.2 Swamp Run Vegetation Monitoring
One vegetation monitoring plot (plot #2) has been established within the swamp run
proper, while two other plots (plots #8 and #10) have been positioned to encompass both
the swamp run and the riverine wetland components of the site. Plots will be 10 meter by
10 meter square plots. Plot sampling will coincide with that of the wetland vegetation
plots and continue for the duration of the 5-year monitoring period or until the site is
deemed successful. Vegetation plot sampling will consist of Level 1: Planted stem
inventory plots for the first year, and Level 2: Total woody stem inventory lots for
remaining years, as defined in the CVS-EEP Protocol for Recording Vegetation Version
• 4.0.
In accordance with the US Army Corps of Engineers, Stream Mitigation Guidelines, April
2003, Albemarle Restorations will maintain survivability of planted woody species at a
minimum of 320 stems/acre through year three. A ten percent mortality rate will be
accepted in year four (288 stems/acre) and another ten percent in year five resulting in a
required minimum survival rate of 260 trees/acre through year five. The vegetation
component of the project will be considered successful if the planted wetland species
dominate the tree and shrub layers in the planted wetland areas. It is expected that
volunteer species will colonize the site from adjacent and nearby wetland and swamp run
areas. If these species become dominant, the wetland indicator status of each species will
be assessed, and the site will be deemed successful if the dominant species in each layer
are FAC or wetter. Non-native invasive species will not be included in this assessment.
3.2 Riverine Wetland Monitoring
3.2.1 Riverine Wetland Hydrology Monitoring
Monitoring of hydrology on the riverine wetland portion of the restoration site will be
completed using seven continuous recording water level loggers suspended in two-inch
PVC monitoring gauges, installed on January 29, 2009. Sheet M-1 of Appendix B shows
locations of the monitoring gauges. The gauges have been located to assess subsurface
• water levels at various elevations on the site and to coordinate with the gauges in the
swamp run. Data will be downloaded from each monitoring gauge four times per year,
ALBEMARLE RESTORATIONS, LLC. 8
Powell Property Wetland and Stream As-Built Plan

• and during each site visit hand measurements will be taken to ensure the accuracy of the
water level loggers.
Groundwater elevation data collected from each monitoring gauge will be presented
relative to the ground surface elevation at the gauge location in graph form to
demonstrate whether wetland hydrology has been attained. Wetland hydrology shall be
defined as inundation or saturation to within 12 inches of the ground surface for a
minimum hydroperiod of 5-8% of the growing season. Based on an average growing
season of 231 days for the project area, using the Lewiston WETS table NRCS data
which is the closest data point available, success criteria shall be attained if wetland
hydrology is achieved within the range of 12 to 19 consecutive days during the growing
season
In addition to measurements of sub-surface water elevations, rainfall data will be
collected on site through an event rainfall logger. This gauge, installed on January 29,
2009, at the edge of the project site, will record rainfall intensity, duration, time, and
quantity. A visual estimate of the extent of inundation will also be made and documented
on site for inclusion into the monitoring report. Rainfall data from two other sites, one
Murfreesboro, North Carolina, approximately 26 miles northwest of the project site and
another in Edenton, North Carolina, approximately 20 miles southeast of the site will be
used as references to determine the deviation from climatologically normal rainfall in the
area. The rainfall data will be assessed to determine degree to which climatologic
extremes (i.e. drought or excessive rainfall) affect project hydrology.
To further gauge the affect of seasonal and annual variations in precipitation and to set a
target hydrologic range for the restored wetlands, a reference site will be monitored near
the restoration area (Sheet R-1, Appendix B). Two hydrologic monitoring gauges were
installed within the reference wetland. The gauges are located in similar position in the
landscape as the restored riverine wetlands, and will be monitored in the same manner as
the project monitoring gauges. In cases where severe drought or other natural
occurrences effect groundwater levels which prevent hydrologic success criteria from
being achieved, data collected at the reference site will be used to verify that fluctuations
in groundwater elevations are due to natural occurrences and not to deficiencies in the
project design.
3.2.2 Riverine Wetland Vegetation Monitoring
Seven vegetation monitoring plots (plots #1, #3 through #7, and #9) have been
established to provide a representative sample of the riverine wetlands while two other
plots (plots #8 and #10) have been positioned to encompass both the swamp run and the
riverine wetland components of the site. Plots are 10 meter by 10 meter square plots. The
initial plot sampling will occur in November 2009 (Year 1), with successive vegetative
monitoring occurring once per year for 5 years, or until the site is deemed successful.
is Vegetation plot sampling will consist of Level 1: Planted stem inventory plots for the first
ALBEMARLE RESTORATIONS, LLC. 9

year, and Level 2: Total woody stem inventory lots for remaining years, as defined in the
CVS-EEP Protocol for Recording Vegetation Version 4.0.
In accordance with the US Army Corps of Engineers, Stream Mitigation Guidelines, April
2003, Albemarle Restorations will maintain survivability of planted woody species
planted to a minimum of 320 stems/acre thru year three. A ten percent mortality rate will
be accepted in year four (288 stems/acre) and another ten percent in year five resulting in
a required minimum survival rate of 260 trees/acre through year five. The vegetation
component of the project will be considered successful if the planted wetland species
dominate the tree and shrub layers in the planted wetland areas. It is expected that
volunteer species will colonize the site from adjacent and nearby wetland areas. If these
species become dominant, the wetland indicator status of each species will be assessed,
and the site will be deemed successful if the dominant species in each layer are FAC or
wetter. Non-native invasive species will not be included in this assessment.
In order to set a target vegetative community for the restored wetlands, a reference site
was chosen which is near to the restoration area (Sheet R-1, Appendix B). The reference
wetland for the target vegetative community is the same wetland where reference gauges
were installed for wetland hydrology monitoring. Vegetation in the reference wetland is
dominated by woody plants including sweet bay magnolia (Magnolia virginiana), willow
oak (Quercus phellos), water oak (Quercus nigra), red maple (Acer rubrum), loblolly
pine (Pinus taeda), sweet gum (Liquidambar styraciflua), black gum (Nyssa sylvatica),
and canebrake (Arundinaria gigantea). A Routine Wetland Determination Data Form
was completed for the reference wetland and is included in Appendix D.
4.0 Maintenance and Contingency
Maintenance of the site is expected to be minimal, as the site is proposed to function as a
natural system. Periodic visual site inspections (four to five times per year) will be
conducted to check for any issues of concern. If any of the following contingencies or
issues arises during monitoring, Albemarle Restorations will take the necessary
maintenance or corrective actions.
The main concern for the site is the introduction of non-native invasive species. No
invasive species were encountered during construction, and the site will be monitored to
ensure that such species do not become established. If invasive species are found,
corrective action including spraying, mowing, or removing such species will be
conducted if the invasive species are determined to be detrimental to the project's
success.
If installed woody plant material is seen having a survival rate of less than 320
stems/acre, replanting will occur to maintain the required percent survival rate during the
first three years of monitoring.
is If gauge data shows that wetland hydrology has not been achieved, the gauge data will be
analyzed in relation to the reference wetland gauge data and rainfall data obtained on-site
ALBEMARLE RESTORATIONS, LLC. 10

and off-site to determine if drought or drier than normal conditions have existed in
coincidence with periods of non-attainment of wetland hydrology. If this is found to be
the case, AR will ask that the site be evaluated during normal climatic conditions. If it is
determined that wetland hydrology has not been achieved, corrective action will be taken
to enhance wetland hydrology to the site.
Other potential issues including animal damage, disease or pest infestation, or damage
from extreme weather events will be noted during monitoring, with any apparent problem
areas mapped for inclusion into the monitoring report. The monitoring will also include
any corrective actions taken or proposed.
