EXECUTIVE SUMMARY
This mitigation plan has been written in conformance with the requirements of the following:
• Federal rule for compensatory mitigation project sites as described in the Federal Register Title
33 Navigation and Navigable Waters Volume 3 Chapter 2 Section § 332.8 paragraphs (c)(2)
through (c)(14).
• NC Department of Environment and Natural Resources (NCDENR) Ecosystem Enhancement
Program (EEP) In -Lieu Fee Instrument signed and dated July 28, 2010
These documents govern EEP operations and procedures for the delivery of compensatory mitigation.
Ecological Engineering, LLP (Ecological Engineering) has entered into an open services design contract with
EEP to provide designs and construction management for stream and wetland restoration within the
Pasquotank River Basin (US Geological Survey 8 -digit Hydrologic Unit Code 03010205). Professional services
associated with this contract will be performed at the Watts Property, also referred to as the Site, Watts Site
or Project Site. This property is situated along Durants Neck peninsula in Perquimans County, approximately
11 miles east - southeast of Hertford and nine miles south - southwest of Elizabeth City (Figure 1). The purpose
of this project is to restore the headwater stream and wetland complex that likely existed prior to the Site's
conversion to agriculture.
Goals and Objectives
The proposed project will be implemented within the confines of one State of North Carolina -owned
property parcel covering 48.09 acres. The overall goal of this project is to provide an ecological uplift to the
Project Site and its surrounding area. This uplift will be provided via modifications to the existing channel and
subsequent drainage network that currently exist at the Project Site. Designs will be based on USACE (2005)
guidance, reference information and professional judgment. A copy of the USACE (2005) guidance is
presented in Appendix A. This goal is in accordance with the defined restoration goals (NCDENR, 2009) for
the Pasquotank River Basin which includes the NC Coastal Habitat Protection Plan (Street et.al., 2005). The
goals are:
• Improve effectiveness of existing rules and programs protecting coastal fish habitats.
• Identify, designate, and protect strategic habitat areas.
• Enhance habitat and protect it from physical impacts.
• Enhance and protect water quality.
The objectives are to design a headwater stream and wetland system with the appropriate cross section and
slope that ultimately provides the proper physical characteristics to supply intended functions and meet
success criteria. In addition to cross section and slope, hydraulic stability and native vegetation establishment
will also contribute to the overall functionality of the system.
The ecological uplift will include the restoration of ecological function, the improvement of overall water
quality and enhancement of native wildlife habitat. Three main components, stream, wetland and riparian
buffer restoration, will serve as the dominant inputs for achieving this goal.

Watershed and Watershed Planning Information
The Project Site is part of the US Geological Survey (USGS) 14 -digit Hydrologic Unit Code (HUC)
03010205060020 and the NC Division of Water Quality (NCDWQ) subbasin 03- 01 -52. An unnamed tributary
(UT) to the Little River is the primary water feature at the Site. This channelized, first order conveyance
bisects the property from south to north. Ecological Engineering utilized planning and existing watershed
information from the NC Department of Environment and Natural Resources (NCDENR) Basinwide Planning
Program, 303(d) Listing, the Pasquotank River Local Watershed Plan and NCDENR EEP Pasquotank River Basin
Restoration Priorities, dated September 2009. The Project Site is not within a Targeted Local Watershed
(TLW), as defined by EEP. Nor, is there any information regarding the specific subbasin in the Local
Watershed Plan (LWP). Goals for the watershed, based on the existing available resources, are presented in
the preceding paragraph.
Existing Amount of Streams and Wetlands
Based on survey data, approximately 1,505 linear feet of jurisdictional stream channel and 0.06 acres of
jurisdictional wetlands currently exist at the Project Site. These lengths and acreages were confirmed by the
US Army Corps of Engineers ( USACE) in September 2010.
Proposed Design Approach
Ecological Engineering will provide designs for the restoration of approximately 1,505 linear feet of
Headwater Forest, approximately 20.4 acres of Hardwood Flat and approximately 26.8 acres upland buffer. In
addition, approximately 0.06 acres of Hardwood Flat will be enhanced via supplemental planting. Wetland
restoration work will occur in combination with stream restoration work along the existing unnamed
tributary. The current drainage network used to drain the property for agricultural operations will be
removed from the interior portion of the Site. The remaining onsite areas not defined as either stream or
wetland restoration will be planted with native riparian and /or non - riparian vegetation depending on their
landscape position.
Stream restoration will follow guidance provided in the document entitled Information Regarding Stream
Restoration in the Outer Coastal Plain of North Carolina released in 2005 by the USACE and NC Division of
Water Quality (NCDWQ). This guidance provides improved methodology associated with the restoration of
zero and first order streams in the outer Coastal Plain physiographic province. The channelized UT currently
functions as a conduit to quickly and effectively remove both surface and groundwater from the Site and
accompanying watershed. By converting its current characteristics to those associated more with a
headwater stream system, the UT will ultimately provide opportunities for water quality improvement.
Wetland restoration will be implemented via the removal of the existing drainage network. The current
network includes a combination of both lateral and linear drainages that manipulate groundwater to allow
for the planting and continuous maintenance of agricultural row crops. Any excess runoff will be filtered
through a vegetated buffer prior to entering the unnamed tributary.
The combination of both stream and wetland restoration at this site will immediately improve water quality
outputs. Ecological functions will be restored, as well as the enhancement of native wildlife habitat.

Jurisdictional Wetland Impacts
No impacts will occur to jurisdictional wetlands as a result of project implementation. One jurisdictional
wetland along the northeastern perimeter of the property will be enhanced as part of the project. The
enhancement work will include planting of native hardwood species.

SECTION 1.0 RESTORATION PROJECT GOALS AND OBJECTIVES
1.1 Overarching Goals and Applications of Mitigation Plans
According to USACE and NCDWQ (2005), restoration of stream pattern, dimension and profile is not often
appropriate in features appearing as zero to first order, headwater streams in the outer Coastal Plain.
Projects constructed in these areas may still qualify for stream restoration even though they may not include
construction of an actual channel. Credits will be calculated based on the length of the valley rather than an
exact length of the channel. Since a 50 -foot buffer is typically required for stream mitigation projects, areas
outside of this 100 -foot corridor but within the valley feature may be used as riparian wetland mitigation.
The width of the valley is defined using the edge of the valley slope. Mitigation outside of and /or above this
valley is considered non - riparian wetland mitigation assuming restoration of wetland hydrology, hydric soils
and hydrophytic vegetation are present ( USACE and NCDWQ, 2005).
The timely and cost effective delivery of sustainable ecological uplift will meet compensatory mitigation
requirements. Without excavation and fill, the Project Site would likely never revert back to pre - disurbance
conditions due to the existing drainage network. This network would eventually lose efficiency; however, it
would continue to function to remove excess surface and groundwater from the Site. In addition, natural
uplift via succession without any supplements would take significantly longer to form climax community
types. Based on these conditions, earthwork and the reestablishment of native vegetation will be necessary
for Site uplift.
Intervention via earthwork and planting will be conducted to the minimal extent practicable to ensure that
project goals and objectives are met. The approach is formulated to provide a jump start or accelerated
schedule for transformation of the Site. Factors of influence are based mainly on physical parameters,
including soil types and characteristics, topography, project constraints and various other attributes
discussed earlier in this document. These have been studied and compared with existing reference
information to aid in design development. Based on existing Site conditions, earthwork and the planting of
vegetation are necessary to ensure that effective transformation takes place. These aspects ultimately justify
the proposed level of intervention.
1.2 Watershed Goals and Objectives
The Watts Site is located in the 03010205 Catalogue Unit (CU), in the Pasquotank River Basin. According to
the Pasquotank River Basin Restoration Priorities (EEP, 2009), the Pasquotank CU offers an array of assets,
including but not limited to large forested tracts and conservation areas. An important priority is to promote
projects that reestablish riparian buffers and corridors of substantial width to improve connectivity of these
protected areas. Agricultural impacts are also prevalent throughout the CU, including nonpoint source runoff
and hydrologic modification. Projects that address agricultural runoff are important. The watershed will also
benefit from stream restoration projects that reestablish more natural pattern, hydrology and habitat,
especially in heavily ditched headwater areas. Additionally, this CU has an abundance of diverse marsh
habitats along an extensive shoreline. Wetland and marsh restoration projects, as well as shoreline
stabilization are high priorities for areas prone to erosion from natural exposure or from heavy boat traffic.
Finally, in developed areas like Elizabeth City, Manteo and the Outer Banks, projects that address stormwater
runoff and treatment are of primary importance (EEP, 2009). This document is available via:

Restoration goals for CU 03010205 identified in the 2009 Pasquotank RBRP include supporting
implementation of the NC Coastal Habitat Protection Plan (Street et. al., 2005) and its associated
implementation plans. The three commissions, including the North Carolina Marine Fisheries, Environmental
Management, and Coastal Resources Commissions unanimously adopted the North Carolina Coastal Habitat
Protection Plan (CHPP) in December 2004. This plan recognizes the importance of North Carolina's coastal
fisheries resources and the commercial and recreational fisheries they support. The continued existence and
enhancement of these resources depend on the health of the aquatic habitats they occupy. The commissions
all agree that they will work in unison to accomplish the following goals:
• GOAL 1— Improve effectiveness of existing rules and programs protecting coastal fish habitats.
• Enhance enforcement of, and compliance with, Coastal Resources Commission (CRC),
Environmental Management Commission (EMC), and Marine Fisheries Commission (MFC)
rules and permit conditions.
• Coordinate and enhance water quality, physical habitat, and fisheries resource monitoring
(including data management) from headwaters to the nearshore ocean.
• Enhance and expand educational outreach on the value of fish habitat, threats from human
activities, effects of non - native species, and reasons for management measures.
• Coordinate rulemaking and enforcement among regulatory commissions and agencies.
• GOAL 2 — Identify, designate, and protect strategic habitat areas.
• Evaluate potential Strategic Habitat Areas by:
• Coordinating, completing, and maintaining baseline habitat mapping (including
seagrass, shell bottom, and other bottom types) using the most appropriate
technology,
• Selective monitoring of the status of those habitats, and
• Assessing effects of land use and human activities on those habitats.
• Identify and designate Strategic Habitat Areas using ecologically based criteria.
• Analyze existing rules and enact measures needed to protect Strategic Habitat Areas.
• Improve programs for conservation (including voluntary actions) and acquisition of areas
supporting Strategic Habitat Areas.
• GOAL 3 — Enhance habitat and protect it from physical impacts.
• Greatly expand habitat restoration, including:
• Creation of subtidal oyster reef no -take sanctuaries, and
• Re- establishment of riparian wetlands and stream hydrology.
• Prepare and implement a comprehensive beach and inlet management plan that addresses
ecologically based guidelines, socio- economic concerns, and fish habitat.
• Protect Submerged Aquatic Vegetation (SAV), shell bottom, and hard bottom areas from
fishing gear effects through improved enforcement, establishment of protective buffers
around habitats, and further restriction of mechanical shellfish harvesting.
• Protect fish habitat by revising estuarine and public trust shoreline stabilization rules using
best available information, considering estuarine erosion rates, and the development and
promotion of incentives for use of alternatives to vertical shoreline stabilization measures.
• Protect and enhance habitat for anadromous fishes by:
• Incorporating the water quality and quantity needs of fish in surface water use
planning and rule making, and
• Eliminating obstructions to fish movements, such as dams, locks, and road fills.
Watts Property Mitigation Plan— Perquimans County, NC Page 2
March 2011

• GOAL 4 — Enhance and protect water quality.
Point sources
• Reduce point source pollution from wastewater by:
• Increasing inspections of wastewater treatment facilities, collection infrastructure,
and land disposal sites, and
• Providing incentives for upgrading all types of wastewater treatment systems.
• Adopt or modify rules or statutes to prohibit ocean wastewater discharges.
• Prohibit new or expanded stormwater outfalls to coastal beaches and to coastal shellfishing
waters (EMC surface water classifications SA and SB) except during times of emergency (as
defined by the Division of Water Quality's Stormwater Flooding Relief Discharge Policy) when
public safety and health are threatened, and continue to phase -out existing outfalls by
implementing alternative stormwater management strategies.
Non -point sources
• Enhance coordination with, and financial /technical support for, local government actions to
better manage stormwater and wastewater.
• Improve land -based strategies throughout the river basins to reduce non -point pollution and
minimize cumulative losses to wetlands and streams through voluntary actions, assistance,
and incentives, including:
• Improved methods to reduce sediment pollution from construction sites, agriculture,
and forestry,
• Increased on -site infiltration of stormwater,
• Documentation and monitoring of small but cumulative impacts to wetlands and
streams from approved, un- mitigated activities,
• Incentives for low- impact development,
• Increased inspections of onsite wastewater treatment facilities,
• Increased water re -use and recycling.
• Improve land -based strategies throughout the river basins to reduce non -point pollution and
minimize cumulative losses to wetlands and streams through rule making, including:
• Increased use of effective vegetated buffers,
• Reduction of impervious surfaces where feasible and reduction of the level of
impervious surface allowable in the absence of engineered stormwater controls,
• Expansion of CAMA Areas of Environmental Concern (AECs) upstream and landward,
• Consideration of erosion rates as an additional factor in the siting of structures along
estuarine and public trust shorelines.
• Develop and implement a comprehensive coastal marina and dock management plan and
policy for the protection of shellfish harvest waters and fish habitat.
• Reduce non -point source pollution from large -scale animal operations by the following
actions:
• Support early implementation of environmentally superior alternatives to the
current lagoon and spray field systems as identified under the Smithfield Agreement
and continue the moratorium on new /expanded swine operations until alternative
waste treatment technology is implemented,
• Seek additional funding to phase -out large -scale animal operations in sensitive areas
and relocate operations from sensitive areas,
• Use improved siting criteria to protect fish habitat.
Watts Property Mitigation Plan— Perquimans County, NC Page 3
March 2011

According to the Pasquotank RBRP (2009), EEP is committed to advancing these goals by supporting efforts
to:
• Develop additional Strategic Habitat Areas (SHAs) and coordinate data and methodology
improvements with other state and federal agencies.
• Map, monitor and restore SAV.
• Improve and restore shellfish beds.
• Implement agricultural BMPs to reduce nonpoint source inputs to the estuary.
• Remove barriers to anadromous fish movement and improve nursery and spawning habitats.
• Protect, augment and connect Natural Heritage Areas and other conservation lands.
EEP will actively develop projects that can coincidentally meet CHPP objectives while meeting its primary
mitigation requirements within designated planning areas. The program will continue to promote innovative
coastal mitigation methods such as the split function crediting strategy proposed expert panels in the White
Oak Local Watershed Plan project titled Coordinating Compensatory Mitigation Requirements to Meet the
Goals of the Coastal Habitat Protection Plan (2009).
1.3 Project Site Goals and Objectives
The Watts Site was identified as a stream, wetland and buffer restoration opportunity to improve water
quality, habitat and hydrology within the CU. The Project Site is part of the US Geological Survey (USGS) 14-
digit Hydrologic Unit Code (HUC) 03010205060020 and the NC Division of Water Quality (NCDWQ) subbasin
03- 01 -52. An unnamed tributary (UT) to the Little River is the primary water feature at the Site. This
channelized, first order conveyance bisects the property from south to north. Ecological Engineering utilized
planning and existing watershed information from the NC Department of Environment and Natural
Resources (NCDENR) Basinwide Planning Program, 303(d) Listing and the Pasquotank River Local Watershed
Plan. The Project Site is not within a Targeted Local Watershed (TLW), as defined by EEP. Nor, is there any
information regarding the specific subbasin in the Local Watershed Plan (LWP).
The main stressors and impacts to watersheds are pervasive and to a large extent, transcend physiography.
As a result, overlapping of goals formulated to address these stressors and impacts often occurs. To
compensate for this aspect when working on individual project sites, a combination of goals and objectives
are presented. Project goals often broadly stated and standardized; therefore, project specific objectives
have been provided to assist with this project's approach to restoration. By properly understanding issues,
stressors and specific project concerns, an appropriate project design can be achieved that is instrumental in
the development of tailored, measurable and achievable goals.
Existing watershed and project stressors at the Project Site appear to be generated predominately by
agricultural related activities. These activities cause channel degradation, systemic sedimentation, buffer
deforestation, riparian compaction, compaction of wetland vegetation and soils, eutrophication and
promotion of invasive, non - native vegetation biomass and seed sources. The effects with regard to ecological
services and /or functions lost and requiring replacement and /or enhancement are transport of watershed
sediments in equilibrium, treatment of lateral overland flow, treatment of groundwater, provision of
instream habitat, provision of wetland habitat, provision of riparian buffer habitat, processing of organic
matter inputs and temporary sediment storage.
This uplift will include the restoration of ecological function, the improvement of overall water quality and
enhancement of native wildlife habitat. Three main components, stream, wetland and riparian buffer
restoration, will serve as the dominant inputs for achieving this goal.

Furthermore, project objectives are to design a headwater stream and wetland system with the appropriate
cross section and slope that ultimately provides the proper physical characteristics to supply intended
functions and meet success criteria. In addition to cross section and slope, hydraulic stability and native
vegetation establishment will also contribute to the overall functionality of the system.
Stream restoration will follow guidance provided in the document entitled Information Regarding Stream
Restoration in the Outer Coastal Plain of North Carolina released in 2005 by the USACE and NCDWQ. This
guidance provides improved methodology associated with the restoration of zero and first order streams in
the outer Coastal Plain physiographic province. The UT is currently channelized. Its purpose is to act as a
conduit to quickly and effectively remove both surface and ground water from the Site and its accompanying
watershed. By converting its current characteristics to those associated more with a headwater stream
system, the UT will ultimately provide opportunities for water quality improvement.
Wetland restoration will be implemented via the removal of the existing drainage network. The current
network includes a combination of both lateral and linear drainages that manipulate groundwater to allow
for the planting and continuous maintenance of agricultural row crops. Surface water at the Site will be
allowed to properly percolate. Any excess runoff will be filtered through vegetation prior to entering the UT.
The combination of both stream and wetland restoration at this site will immediately improve water quality
outputs. Ecological functions will be restored, as well as the enhancement of native wildlife habitat.
The Watts Site was identified as a stream, wetland and buffer restoration opportunity to improve water
quality, habitat and hydrology within the CU. The Project Site is part of the US Geological Survey (USGS) 14-
digit Hydrologic Unit Code (HUC) 03010205060020 and NCDWQ subbasin 03- 01 -52. An unnamed tributary
(UT) to the Little River is the primary water feature at the Site. This channelized, first order conveyance
bisects the property from south to north. Ecological Engineering utilized planning and existing watershed
information from the NC Department of Environment and Natural Resources (NCDENR) Basinwide Planning
Program, 303(d) Listing and the Pasquotank River Local Watershed Plan. The Project Site is not within a
Targeted Local Watershed (TLW), as defined by EEP. Nor, is there any information regarding the specific
subbasin in the Local Watershed Plan (LWP).
The overall goal of this project is to provide an ecological uplift to the Project Site and its surrounding area.
This uplift will be provided via modifications to the existing channel and subsequent drainage network that
currently exist at the Project Site. Designs will be based on USACE and NCDWQ (2005) guidance, reference
information and professional judgment. This goal is in accordance with the abovementioned goals for the CU
and includes the following Site - specific goals:
• restore ditched wetlands to improve the habitat, fishery and flood control functions;
• reduce sediment loading and other pollutants from surface runoff by increasing the soil
retention, filtration and nutrient uptake functions of wetland and riparian areas;
• restore and protect wildlife corridors and other key links to high -value habitat areas; and
• restore and protect natural breeding, nesting and feeding habitat to promote species richness
and diversity.
Watts Property Mitigation Plan— Perquimans County, NC Page 5

The objectives are to design a headwater stream and wetland system with the appropriate cross section and
slope that ultimately provides the proper physical characteristics to supply intended functions and meet
success criteria. In addition to cross section and slope, hydraulic stability and native vegetation establishment
will also contribute to the overall functionality of the system.
The existing pre- restoration baseline depicts a channelized stream surrounded by a network of linear and
lateral ditches. The Site is drained in its entirety, aside from a very small wetland area (0.06 acres) along the
northeastern perimeter. Both the existing channel and wetland are considered jurisdictional. Impacts to
these two resources will be considered minimal, if any. The existing base elevations of the channel will
remain the same; however, its dimension will be significantly altered and thus requiring submittal and
approval of a Nationwide Permit 27 (Section 404) and its corresponding water quality certification (Section
401), as well as a likely consistency determination from the NC Division of Coastal Management. The pattern
of the tributary will be minimally altered. It is expected that the resulting headwater, first order channel will
have little or no actual meanders. No impacts are proposed to the jurisdictional wetland area. Once
earthwork is complete, the entire site will be planted with native vegetation. The other permit that will be
required is a land disturbance permit. Erosion and sediment control measures will be implemented to their
fullest extent to ensure that any impacts to water resources downstream are minimized to their fullest
extent during and immediately after construction.

2.2 Site Selection
The Watts Property was purchased fee simple by the State of North Carolina in 2004 for the purposes of
mitigation. It is situated in Perquimans County, along Durants Neck Peninsula separating the Perquimans
River, Little River and Albemarle Sound. The majority of the waters associated with the Site drain into an
unnamed tributary to the Little River. The Project Site and its surrounding area are all part of the Pasquotank
River Basin. Figures 2 through 4 depict the Site's watershed, underlying soils and current conditions. In
addition, historical aerials and Site photographs are also provided at the end of this Section.
The following information pertains to project components and structure with regard to the headwater
stream restoration of the UT, non - riparian wetland restoration and the restoration of upland buffer. This
information is summarized in Table 1. Based on existing survey data, implementation of the project will
provide approximately 1,505 linear feet of Headwater Forest stream restoration, 20.4 acres of Hardwood Flat
wetland restoration and 0.06 acres of Hardwood Flat wetland enhancement. In addition, the remaining 26.8
acres at the Project Site will serve as buffer. Additional information pertaining to the Project's components
and structure is provided in Section 5.0 entitled Determination of Credits.

March 2011

As previously mentioned, headwater stream restoration will follow guidance provided in the document
entitled Information Regarding Stream Restoration in the Outer Coastal Plain of North Carolina released in
2005 by the USACE and NCDWQ. This guidance provides improved methodology associated with the
restoration of zero and first order streams in the outer Coastal Plain physiographic province. The existing UT
is a prime candidate for this type of restoration due to its location, state of channelization, current
hydrological characteristics and absence of physical constraints. By converting its physical components to
those associated more with a headwater stream system, the UT will ultimately provide opportunities for
water quality improvement.
Wetland restoration will be implemented via the removal of the existing drainage network. The current
network includes a combination of both lateral and linear drainages that manipulate groundwater to allow
for the planting and continuous maintenance of agricultural row crops. This network will be removed from
the interior portion of the Site. As a result, surface water at the site will be allowed to properly percolate.
Any excess runoff will be filtered through vegetation prior to entering the UT.
Buffers, extending more than 200 feet outward will be established along the UT and remaining areas not
utilized for wetland restoration. Although no additional credits are anticipated, these buffers will function to
provide additional water quality enhancement, stormwater and floodwater management, streambank and
shoreline stabilization, water temperature modification, wildlife habitat and absorption of airborne
pollutants. Ultimately the Site restoration efforts will result in the reduction of nutrient and sediment export
from the Site into the Little River.

Existing conditions surveys were completed during the early spring of 2010. These surveys included natural
resources assessments, protected species assessments, jurisdictional wetland delineations and topographic
assessments. Field surveys were undertaken to determine natural resource conditions and to document
Waters of the United States. No detailed morphological surveys were completed along the existing channel,
which currently functions as a drainage ditch removing both surface and groundwater from the Project Site.
4.1 Watershed Summary Information
4.1.1 Drainage Area, Proiect Area and Easement Acreage
The watershed associated with the UT is rural, consisting predominantly agricultural lands with a small mix of
forest lands. Figure 2 provides an aerial view of the watershed. The drainage area, calculated from the
culvert under Norma Drive at the downstream end of the Site covers approximately 0.21 square miles (136
acres). Drainage at the Watts Property is via an onsite drainage network connected with one first order
stream channel that bisects the Site. No impervious services were noted within the watershed encompassing
the Site and it surrounding areas.
Landuse within the Project Area is agricultural. Row crops were planted through 2004 by the previous
property owner. Since this time, it has remained fallow. The existing drainage network however, is still
functioning as originally intended; effectively draining the Site. The drainage area including and surrounding
the Site is comprised of a network of exterior and interior drainage ditches emptying into a first order stream
channel. These ditches help to remove both surface and groundwater from the Site. One drainage outlet is
responsible for removing the majority of water from the Project Site. This outlet is along the northern edge
of the property and consists of a channel that flows under Norma Drive and discharges immediately into the
Little River. One other outlet is connected to the perimeter network of ditches at the northwestern corner of
the property.
4.1.2 Surface Water Classifications and Water Quality
The Project Site is situated within NCDWQ subbasin 03 -01 -52 of the Pasquotank River Basin. This basin is part
of the Albemarle - Pamlico Estuarine System, the second largest estuarine system in the United States
(NCDWQ, 2007). The subbasin consists of the northwestern edge of the Albemarle Sound and includes the
Little and Perquimans Rivers. The subbasin covers a total area of approximately 541 square miles, separated
within by 399 square miles of land and 142 square miles of water (NCDWQ, 2007).
According to NCDWQ (2009b), the UT's surface water classification is the same as its receiving water, the
Little River. The Little River is classified as Class SC waters, which denotes saltwaters protected for secondary
recreation, fishing, aquatic life propagation and survival, and wildlife (NCDWQ, 2009b). The UT within the
Watts Property receives its flow from both surface and groundwater with little to no saltwater intrusion
except in the case of backwater flow from storm surges. As a result, the classification under normal
circumstances would be Class C, which denotes freshwaters protected for aquatic life propagation and
survival, fishing, wildlife, secondary recreation, and agriculture.
Watts Property Mitigation Plan— Perquimans County, NC Page 16
March 2011

Watts Property Mitigation Plan— Perquimans County, NC Page 17
March 2011

No High Quality Waters (HQWs), Outstanding Resource Waters (ORWs), or Special Management Strategy
Areas exist within five miles of the study area.
NCDWQ (2007) denotes four minor National Pollutant Discharge Elimination System (NPDES) discharges in
this subbasin with a total permitted flow of 0.7 MGD. Three of these facilities are water treatment plants. In
addition, there are three non - discharge permits and six stormwater discharge permits identified in the
subbasin (NCDWQ 2007). None of the dischargers are situated along or adjacent to the Little River.
Section 303(d) of the Clean Water Act (CWA) requires states to develop a list of waters not meeting water
quality standards or which have impaired uses. Listed waters must be prioritized, and a management
strategy or total maximum daily load (TMDL) must subsequently be developed for all listed waters. The Little
River, downstream of the UT, is currently listed on North Carolina's 303(d) List. It was originally listed in 2000
under the standard violation for low dissolved oxygen (NCDWQ, 2009a). According to NCDWQ (2009a),
potential sources(s) include, but are not limited to, agriculture and onsite wastewater systems (septic tanks).
4.1.3 Physiography, Geology and Soils
The Coastal Plain physiographic province is the largest geologic belt in the state. It consists of a wedge of
mostly marine sedimentary rocks that gradually thickens to the east. The most common sediment types are
sand and clay, with limestone ever - present in the southern portion. According to Lapham and Lyman (1905),
the Project Site is geologically underlain by the Columbia Formation. This formation is built up from mineral
materials transported by streams from the Piedmont physiographic province and deposited as sediments of
various grades of fineness, at a time in geological history when the coast of North Carolina was submerged
under the edge of the Atlantic Ocean. The distribution of these sediments was controlled by varying current
and wave action, modified to some extent by stream erosion after the emergence of the land. The texture of
some of the soil types has also been modified in a measure by the incorporation of considerable amounts of
organic mater, resulting from the decay of quantities of vegetation (Lapham and Lyman, 1905).
The soils underlying the Watts Property are dominated by the Roanoke Series, with the exception of the
northern portion where the tributary exits under Norma Drive, which is underlain by the Dogue Series. The
locations of these soils are provided on Figure 3. Both the Roanoke and Dogue Series exhibit similar
characteristics such as their pH (acidic), depths to restrictive features (more than 80 inches), slopes (zero to
two percent), available water capacity (high, between 9.2 and 9.3 inches) and their parent material (loamy
and clayey fluviomarine deposits. Roanoke soils however, differ from Dogue soils in landform position,
drainage class, depth to water table and profile. Soil borings were conducted across the Site to verify mapped
locations. The results are presented in Appendix D and are discussed later in the document. The locations of
the borings are presented on Figure 4 along with the hydrologic features described in the following section.
According to the Natural Resources Conservation Service (2009), Roanoke silt loam occurs along depressions
and flats on marine terraces. Its drainage class is poorly drained and the depth to water table varies between
zero and 12 inches (NRCS, 2009). The typical profile of Roanoke silt loam is provided in the chart below. This
soil is identified as a hydric soil, or soil that is formed under conditions of saturation, flooding or ponding long
enough during the growing season to develop anaerobic conditions in the upper portion.
Dogue fine sandy loam occurs along the ridges on marine and stream terraces. This soil is moderately well
drained and exhibits an average depth to the water table between 18 and 36 inches (NRCS, 2009).

The growing season is calculated as the period between the average date of the last killing frost in the spring
and the average date of the first killing frost in the fall. The closest climate station to the Project Site is in
Elizabeth City. According to Gregory (2000), the growing season consists of 246 days and begins on March 18
and ends on November 19.
4.1.4 Existing Hydrological Features
As previously noted, the current landuse is agriculture and the existing drainage network confirms its
intended use. This network was installed to remove both surface and groundwater from the property in a
quick and efficient manner. The on -site network includes an internal assemblage of nine intersecting ditches
of varying dimensions that total more than 4,500 linear feet in length and a perimeter network totaling more
than 4,200 linear feet. The majority of the internal ditches drain into the UT that bisects the Project Site while
externally, the perimeter ditches on the west, south and eastern side empty into the UT. The ditch along the
northeast side also drains into the UT, although it is downstream of the Site and the ditch situated along the
northwest corner drains into another UT west of the Site. These ditches range from approximately eight
inches to three feet in depth and two to eight feet in top width. The UT, on the other hand, ranges between
three and four feet in depth and six and ten feet in width. Its total length is approximately 1,505 linear feet.
Existing pipes are located near the junctions of several of the ditches, as well as along the UT. These pipes
were identified as either corrugated metal pipe (CMP), iron pipe (IP) or corrugated plastic pipe (CPP) and
range in diameter between 12 and 24 inches. The primary function of the pipes is to provide access for
equipment to cross the drainage network.
The UT exits the Project Site through a pipe under Norma Drive. This pipe appears to be a 24 -inch CMP and is
completely submerged at both ends. Over the past several years, headwall erosion has been slowly
compromising this pipe and Norma Drive. Excessive sedimentation exists within the pipe and portions of the
pipe are corroding. This pipe will be upgraded to two 36 -inch corrugated aluminum pipes (CAP) during
project implementation to ensure the hydrologic trespass does not occur upon its ultimate failure.
Watts Property Mitigation Plan— Perquimans County, NC Page 21
March 2011

4.1.5 Vegetation Community Type Descriptions and Disturbance History
Terrestrial plant communities at the Watts Property have been significantly altered from their natural states
and currently fall under the Agricultural — Row Crops classification. Although the Site is currently in a state of
fallow, this area consists almost entirely of herbaceous vegetation, including seasonal grasses and weeds. An
historical aerial photograph, dated 1975, is depicted in the following sub - section. This photograph shows the
Site as forested, further confirming the overall restoration goal of the project.
Common species observed were clover (Trifolium sp.), dogfennel (Eupatorium capillifolium), ragweed
(Ambrosia sp.), Japanese honeysuckle (Lonicera japonica), thistle (Carduus sp.), Joe -pye -weed (Eupatorium
fistulosum), dandelion (Taraxacum officinale), broomsedge (Andropogon sp.), fescue (Festuca sp.), blackberry
(Rubus sp.), onion (Allium sp.), foxtail grass (Setaria sp.), aster (Aster sp.), vetch (Vicia sp.) and henbit
(Lamium sp.). Within the drainage network, soft rush (Juncus effusus), smartweed (Polygonum sp.),
duckweed (Lemna sp.), and seedbox (Ludwigia sp.) were observed. In addition, several pioneer woody
species have begun to establish themselves. These species included loblolly pine (Pinus taeda), black cherry
(Prunus serotina), baccharis (eaccharis halimifolia) and several oaks (Quercus spp.).
4.1.6 Historical Land Use and Development Trends
Based on a review of landuses and development throughout the Project and surrounding areas, little has
changed for the past several decades. More residential development has occurred downstream of the Site
along the Little River. The area west, east and south has remained unchanged. It is anticipated that over the
next couple of decades, growth will occur primarily in the form of residential housing. As a result, the overall
amount of impervious surface is expected to increase within this and the adjacent watersheds.
A review of aerial photographs was conducted as part of the preparation of the Environmental Resource
Technical Report (ERTR). It appears that major land disturbance activities including the conversion from
forest to agriculture occurred between 1975 and 1983. In addition, to the 1975 photograph, other recent
aerial photographs are provided in Appendix C.
According to Community Planning Collaborative, Inc. (2006), Perquimans County envisions the majority of
residential development will continue to be in residential subdivisions, within Hertford and Winfall, and to a
limited degree along State maintained roads. The State projects that Perquimans County's population will
grow from 11,890 persons in 2005 to 12,647 persons by 2015, and 13,011 persons by 2020. If these
projections hold true, the County will grow by about 1,121 people in the period 2005 — 2020. If residential
construction trends continue (at or near the rate of 168 residential structures per year) until 2020, an
additional 2,520 residential units could potentially be built or placed in Perquimans County. This total would
adequately accommodate the population growth projected. However, this level of residential construction
would involve some conversion of lands from other uses (most notably cleared agricultural lands and
woodlands); additional strip type development along State roads, and the development of additional
subdivisions. At a rate of one acre per home site, over 2,500 acres could potentially be converted to
residential uses, although the actual figure would most likely be much less as development is directed
intosubdivisions which allow for greater densities (CPC, 2006).

4.1.7 Potential Constraints
4.1.7.1 Environmental Screening
Ecological Engineering completed the checklist entitled "Environmental Screening and Document Guidelines
for Ecosystem Enhancement Program Projects (draft date 8.18.05)" in accordance with EEP protocols. This
information is intended to assist EEP in satisfying the Federal Highway Administration's (FHWA) obligation to
ensure compliance with various federal environmental laws and regulations. This obligation is necessary in
order to preserve FHWA's ability to reimburse the NC Department of Transportation ( NCDOT) for costs
incurred for offsetting NCDOT impacts through EEP projects. The signed Categorical Exclusion Form is
provided in Appendix C.
In addition, Ecological Engineering obtained data from Environmental Data Resources, Inc. (EDR) with regards
to environmental risk at or near the Site. The Site is not listed on any of the databases searched by EDR (EDR,
2009). A copy of the report's overall findings and map are presented in the ERTR, dated October 2010.
4.1.7.2 Site Access
Access to the Watts Property is available via Norma Drive, a private road that intersects the northern
perimeter of the Site. No fences, barriers or other obstacles are present to deter access. Directions are
provided in Section 2.1.
4.1.7.3 Utilities and Easements
Based on field observations and associated mapping, two utility poles were noted within the Project Site
along Norma Drive. These poles are likely maintained by the local utility coop and are immediately outside of
the right -of -way associated with Norma Drive. No restoration or enhancement work is proposed within or
immediately adjacent to this area. Otherwise, no other utilities or easements were identified within the
project area.
4.1.7.4 FEMA/ Hydrologic Trespass
According to FEMA (2004), the majority of the UT is situated in a mapped backwater area from the Little
River labeled as Zone AE, where base flood elevations have been determined. There is no established
floodway or non - encroachment area along this tributary. Furthermore, A HEC RAS analysis (results provided
later in the document) denotes no rise in water surface elevations based on proposed conditions. Therefore,
there will be no impact on Federal Emergency Management Agency (FEMA) mapping. FEMA approval will not
be necessary for project implementation. In addition, no floodplain development permit will be required and
no further coordination is anticipated.
A copy of EEP's Floodplain Requirements Checklist and current FEMA Map are provided in Appendix C. This
checklist was submitted to the State Construction Office, National Flood Insurance Program (NFIP), NC
Floodplain Mapping Unit and EEP.
No hydrologic trespass will occur at the Project Site. Its position, including the topography and the existence
of a perimeter ditch along the eastern, southern and western boundaries will prohibit any opportunities for
hydrologic trespass. Portions of the site will be designed to function as a wetland, holding water for extended
periods of time. Drainage will follow natural valley contours which flow towards the UT that bisects the
property. The perimeter drainage ditches will capture any excess surface and /or groundwater and provide
watt ri operty rviltigauUii naii— rerqulinaiu �uunq, ivy. rage 4•

relief to either the UT bisecting the Site or the existing drainage network situated along the property's
northwest corner.
4.2 Regulatory Considerations
4.2.1 Jurisdictional Streams and Wetlands
As per verification by the USACE in 2010, the UT is considered a jurisdictional stream channel. The NCDWQ
Stream Classification Forms for the UT are provided in Appendix C. This form offers a quick, qualitative
assessment based on a numerical system. Scores exceeding 30 represent a perennial or primary stream,
while those between 19 and 30 represent an intermittent or secondary channel. Any scores less than 19
discern the channel as either ephemeral or stormwater- based. The UT scored 25.0 along the upper portion
and 33.25 along the lower portion. This information is generally utilized to address stream mitigation credits;
however, being that the mitigation type proposed for this project includes a first order channel, rather than
perennial or intermittent, it is considered jurisdictional throughout its length. Therefore, mitigation credits
will be offered for its entire length throughout the property.
Jurisdictional wetland determinations were performed using the three - parameter approach as prescribed in
the 1987 Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 1987). Supplementary
technical literature describing the parameters of hydrophytic vegetation, hydric soils, and hydrological
indicators were also utilized. One jurisdictional wetland was observed within the project area (Figure 4). The
wetland is considered low value and is the likely result of a soil confining layer, which significantly slows the
percolation of surface water. Its overall functions are severely limited due to its small size (0.058 acres),
location and surrounding land use. Coordination with the USACE began in March 2010. A request for
jurisdictional determination (JD) was submitted in August 2010 and concurrence was received in September
2010. The approved JD and associated forms are provided in Appendix C.
4.2.2 Endangered Species Act
Certain populations of fauna and flora have been, or are, in decline due to either natural forces or their
inability to coexist with humans. Federal law (under the provisions of Section 7 of the Endangered Species
Act [ESA] of 1973, as amended) requires that any federal action likely to adversely affect a species listed as
federally protected be subject to review by the US Fish and Wildlife Service (USFWS) or National Marine
Fisheries Service (NMFS). Prohibited actions which may affect any species protected under the ESA are
outlined in Section 9 of the Act. Other species may receive additional protection under separate laws such as
the Lacey Act Amendments of 1981, the Migratory Bird Treaty of 1999, the Marine Mammal Protection Act
of 1972, or the Eagle Protection Act of 1940.
Species which are listed, or are proposed for listing, as endangered or threatened are recorded in Section 4
of the ESA. As defined by the Act, an Endangered species is any plant or animal which is in danger of
extinction throughout all or a significant portion of its range within the foreseeable future. A Threatened
species is any species which is likely to become an endangered species within the foreseeable future
throughout all or a significant portion of its range.
Resource investigations were conducted by a qualified scientist during January, February and March 2010.
Field surveys were undertaken to determine natural resource conditions and to document natural
communities, wildlife and the presence of protected species and /or their habitats. Published information
regarding the study area and region and protected species was derived from a number of resources, which
are summarized in the ERTR, dated October, 2010.
Watts Property Mitigation Plan— Perquimans County, NC Page 25
March 2011

According to the USFWS (2010), there are no federal Endangered "E" or Threatened "T" species listed as
potentially occurring in Perquimans County. In addition, there are no known critical habitats listed within two
miles of the project area (USFWS, 2010).
Scoping letters requesting review were sent via US Mail to the USFWS and NC Wildlife Resources Commission
( NCWRC) on January 25, 2010. As of October 31, 2010, no correspondence had been received from either
entity. Therefore, it is determined that neither the USFWS nor NCWRC have any comments regarding
protected species or their habitats with regard to the proposed project. Copies of the letters are provided in
the ERTR, dated 2010.
Species identified as Endangered, Threatened, or Special Concern (SC) by the NC Natural Heritage Program's
(NCNHP's) list of rare plant and animal species are afforded state protection under the State Endangered
Species Act and the North Carolina Plant Protection and Conservation Act of 1979.
According to the USFWS (2010), there are three Federal Species of Concern (FSC) and one species listed
under the Bald and Golden Eagle Protection Act (BGPA) that potentially may occur in Perquimans County.
The NCNHP identifies a total of five species as either state - endangered, threatened or of special concern
( NCNHP, 2009). These species are afforded state protection under the State Endangered Species Act and the
North Carolina Plant Protection and Conservation Act of 1979. The chart presented at the end of this section
depicts the species of importance for Perquimans County, their scientific names, classifications and the
presence of available habitat within the project area.
On -line map reviews at the NCNHP website were conducted on July 15, 2009 and reconfirmed on August 31,
2010. There are no recorded sightings or occurrences of any species denoted by the USFWS or NCNHP
documented within a two mile radius of the Watts Property.

BGPA:
In the July 9, 2007 Federal Register (72:37346- 37372), the bald eagle was declared recovered, and removed
(de- listed) from the Federal List of Threatened and Endangered wildlife. This de- listing took effect August 8,
2007. After de- listing, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668 -668d) becomes the
primary law protecting bald eagles. The Eagle Act prohibits take of bald and golden eagles and provides a
statutory definition of "take" that includes "disturb." The USFWS has developed National Bald Eagle
Management Guidelines to provide guidance to land managers, landowners and others as to how to avoid
disturbing bald eagles.

4.2.3 Historic Preservation Act
Section 106 of the National Historic Preservation Act of 1966 provides that properties and districts listed in or
eligible for listing in the National Register of Historic Places be considered in the planning of federal
undertakings such as highway construction and community development projects. "Federal undertakings"
also include activities sponsored by state or local governments or private entities if they are licensed,
permitted, approved, or funded (wholly or in part) by the federal government. "Federal undertakings" do not
include loans made by banks insured by the FDIC or federal farm subsidies.
There is no absolute protection from federal actions that may affect a historic property. If a federal
undertaking is in conflict with the preservation of a historic property, the State Historic Preservation Office
will negotiate with the responsible federal agency, sometimes with the involvement of the federal Advisory
Council on Historic Preservation, in an effort to eliminate or minimize the effect on the property. This
mitigation procedure applies to properties that are determined eligible for the National Register in the day -
to -day environmental review process as well as those actually listed in the National Register.
Watts Property Mitigation Plan— Perquimans County, NC Page 27
March 2011

North Carolina law (G.S. 121- 12(a)) provides for consideration of National Register properties in undertakings
funded or licensed by the state. Where a state undertaking is in conflict with the preservation of a National
Register property, the NC Historical Commission is given the opportunity to review the case, "giving due
consideration to the competing public interests involved," and make recommendations to the state agency
responsible for the undertaking. The commission's recommendations to the state agency are only advisory.
Properties potentially eligible for but not actually listed in the National Register are not protected under G.S.
121 -12 (a).
No structures, buildings, ruins or other man -made items exist within the area denoted as the Project Site.
Structures, including those associated with private residences and their associated farm buildings exist
outside of the project area; however, none of these will be impacted by the restoration of the stream
channel and enhancement of the surrounding wetland and buffer areas.
No items relating to archaeological resources were observed during the Site visit.
Scoping letters requesting review were sent via US Mail to the NC Department of Cultural Resources, State
Historic Preservation Office (SHPO) and the Tribal Historic Preservation Office (THPO) associated with the
Eastern Band of Cherokee Indians on January 25, 2010. Ecological Engineering received a letter dated
February 9, 2010 from SHPO confirming there are no historic resources that would be affected by the project,
and thus no comment on the undertaking as proposed. No letters or comments have been received from the
Eastern Band of Cherokee Indians. Copies of these scoping letters and the SHPO response are provided in the
ERTR, dated 2010.
4.2.4 Coastal Zone Management Act (CZMA)/ Coastal Area Management Act (CAMA)
Perquimans County is one of 20 counties along the coastal region of North Carolina that is subject to the
rules and policies of the Coastal Resources Commission, which administers the Coastal Area Management Act
(CAMA). Immediately downstream of the Site is an identified Area of Concern (AEC). Generally AECs are
defined as those areas exhibiting areas with navigable waters within the 20 CAMA counties, existing marsh or
wetland areas, areas within 75 feet of the mean high water line along an estuarine shoreline; near the ocean
beach, near an inlet, within 30 feet of the normal high water level of areas designated as inland fishing
waters by the N.C. Marine Fisheries Commission or near a public water supply. The NC Division of Coastal
Management oversees CAMA for permitting purposes.
In addition, Federal consistency authority exists under the Federal Coastal Zone Management Act (CZMA).
This Act was enacted on October 27, 1972, to encourage coastal States, such as North Carolina, to develop
comprehensive programs to manage and balance competing uses of and impacts to coastal resources. It
applies to any activity that is within the State's coastal zone that may reasonably affect any coastal resource
or coastal use within the State's coastal zone (even if the activity occurs outside of the coastal zone), if the
activity is a Federal activity, requires a Federal license or permit, receives Federal money or is a plan for
exploration, development or production from any area leased under the Outer Continental Shelf Lands Act.
4.2.5 Essential Fish Habitat
The 1996 amendments to the Magnuson- Stevens Fishery Conservation and Management Act (Magnuson -
Stevens Act) set forth a new mandate for the National Marine Fisheries Service (NMFS), regional fishery
management councils and other federal agencies to identify and protect important marine and anadromous
fish habitats. The Essential Fish Habitat (EFH) provisions of the Magnuson- Stevens Act support one of the
Nation's overall marine resource management goals - maintaining sustainable fisheries.

March 2011

According to NOAA (2011), no EFH, Habitat Areas of Particular Concern (HAPC) or EFH areas protected from
fishing were identified within the Project boundaries. The remaining portion of the UT downstream of the
Site and the Little River exhibit EFH for all life stages of the red drum (Sciaenops ocellatus).

SECTION 6.0 MITIGATION WORK PLAN
6.1 Stream Project and Design Justification
This section is characterized as a functional balance sheet further establishing the design approach or level of
intervention is proportional and appropriate to the existing conditions at the Site and within the watershed
in order for uplift to be maximized to the fullest extent. Current impairment factors for the Project Site are
considered the following:
• Hydrological: existing channelized conveyance (UT) and surrounding drainage network.
• Impairment Severity: maximum with complete landuse change from previous community type.
• Proportion: entire 48 -acre property parcel.
• Rate of Deterioration: moderate, requiring periodic maintenance.
Although relatively small (136 acres), the contributing watershed also presents several impairment factors.
These factors include:
• Hydrological: existing channelized conveyance (UT) and surrounding drainage network.
• Impairment Severity: moderate with partial landuse changes from previous community type.
• Proportion: throughout.
• Rate of Deterioration: minimal to moderate, requiring periodic maintenance.
The main differences between the Project Site and its surrounding watershed area are that a portion of the
area remains wooded, with mature vegetation. This vegetation has helped to stabilize the channel upstream
of the Site. The area has still been altered through a drainage network though. The remainder of the
watershed consists of agricultural fields.
The abovementioned factors when contrasted and compared with existing features of value including:
standing ecological value of instream habitat complexity; standing ecological value of mature vegetation and
the biological state of the channel and existing wetland areas result in an overwhelming justification for
maximum intervention. The standing ecological values of instream habitat and mature vegetation are
essentially non - existent. In addition, the biological state of the channel and existing wetland areas are
severely compromised due to lack of stability, flow regimes, canopy cover and periodic maintenance. As a
result, the uplift potential for this project is very high.
6.2 Designed Channel Classification and Wetland Types
Stream mitigation credits will be generated via modification of the existing, channelized UT to a headwater,
first order stream channel. These modifications will effect the overall dimension, pattern and profile of the
channel. The classification of a design channel is not applicable in this case. Rather, the entire linear feature
will be restored to function similar to a Headwater Forest Community, as defined by NCWAM (2010) and
discussed in detail later in this section.
The existing interior drainage network will be removed in its entirety and restored to depict a Hardwood Flat
Community. This community type will transition into a Mesic Mixed Hardwood Community throughout the
remainder of the Project Site. The Hardwood Flat Community will occur in the wetter portions of the Site,
primarily those obtaining jurisdictional wetland status while the Mesic Mixed Hardwood Community will
occur along the drier portions.
Watts Property Mitigation Plan— Perquimans County, NC Page 31
March 2011

6.3 Target Wetland and Buffer Communities
As mentioned above, target wetland and buffer communities will be categorized under the Coastal Plain
Headwater Forest, Hardwood Flat and Mesic Mixed Hardwood Communities. According to the Schafale and
Weakley (1990), vegetative communities commonly transition between each other and differences are
generally based on landscape position, hydrology, soil types and dynamics. These communities are all
indicative of the Coastal Plain physiographic province.
6.4 Preliminary Groundwater Characterization
Based on available groundwater information, nearly six years of groundwater data exist at the Project Site.
Initial collection efforts began in December 2003 and ended in December 2004. Following this effort, no data
was available for Year 2005 although the groundwater gauges remained in place. These gauges were
replaced at the beginning of 2010. Once the original gauges were removed from the Site, the manufacturer
was able to extract the additional data from 2006 to 2010. The replacement gauges have been periodically
monitored since their installation and will remain on site until implementation activities begin.
According to EEP (2005), the previous consultant's evaluation of site groundwater included the siting and
installation of a series of groundwater monitoring gauges with electronic data loggers. These gauges were
manufactured by Infinities USA, Inc. and provided by EEP. A total of six were installed along with a 6.5 -inch
diameter, 0.01 -inch, self emptying tipping bucket rain gauge data logger (EEP, 2005). The locations of the
original gauges have been preserved and are depicted on Figure 4. The data associated with these gauges is
provided in Appendix D.
Ecological Engineering replaced the previously installed gauges with Ecotone brand gauges provided from
Remote Data Systems, Inc. As previously mentioned, the original gauges were returned to the manufacturer
and downloaded. The current Ecotone gauges are situated immediately adjacent to the previous gauge
locations to maintain the groundwater data stream. Ultimately, this data will be used to compare the pre -
and post - implementation conditions. The data collected during this time period represents a snap -shot of
groundwater levels compared with precipitation data. Appendix D also depicts existing groundwater and
precipitation data at the Project Site. Based on current data, the existing drainage network is effectively
removing groundwater from the Site.
6.5 Water Budget
Ecological Engineering developed a water budget for the Watts Site to determine the viability of
reestablishing wetland hydrology on this site. The water budget is based on methods presented in Pierce
(1993) "Planning Hydrology for Constructed Wetlands." Development of a water budget requires knowledge
of the hydrologic inputs and outputs, site dimensions, physical properties of the soils present and existing
features on and adjacent to the project site which may affect groundwater hydrology. The water budget
calculations indicate that adequate water is present to meet the proposed hydrologic criteria for the restored
wetlands.
Site constraints limiting the extent of wetland development include a perimeter ditch and Norma Drive at the
lower project boundary. The perimeter ditch must remain in place to avoid hydrologic trespass on adjacent
properties, some of which are currently being used for agriculture. Norma Drive creates the northern
(downstream) project boundary. As previously mentioned, a 24 -inch CMP conveys the UT under the roadway
and roadside ditches provide drainage for the road bed. These features must also remain in place to prevent
erosion from compromising the current road. As a result, both of these constraints limit the extent of
wetland development within the Project Site.
i
watt r operty lViltigaLlUll ridii— rerqui d � wunq, Page 32
March 2011

The water budget results verify the presence of adequate water to meet the proposed wetland hydrology
criteria for the majority of the Project Site. Calculations indicate excess water when comparing inflow to
outflow and by assuming that base channel flow and stormwater flow were zero, these calculations present a
conservative estimate of available water.
6.6 Soil Characterization
As previously mentioned, the soils underlying the Watts Property are dominated by the Roanoke Series, with
the exception of the northern portion where the UT exits under Norma Drive, which is underlain by the
Dogue Series. The soils associated with both the Roanoke and Dogue Series exhibit similar characteristics
such as their pH (acidic), depths to restrictive features (more than 80 inches), slopes (zero to two percent),
available water capacity (high, between 9.2 and 9.3 inches) and their parent material (loamy and clayey
fluviomarine deposits. Roanoke soils however, differ from Dogue soils in landform position, drainage class,
depth to water table and profile. Taxonomic classifications are:
Taxonomic Classifications
Roanoke Silt Loam fine, mixed, semiactive, thermic typic endoaquults
Dogue Fine Sandy Loam fine, mixed, semiactive, thermic aquic hapludults
Ecological Engineering characterized the underlying soils at the Site and compared them with typical profile
information for Roanoke silt loam. Ten soil borings were examined. These borings were randomly located
across the property as a comparison to the mapped underlying series (Figure 4). Based on the results, the
soils appear to be similar with the mapped Roanoke series. This information is provided in Appendix D. Upon
review of the data, it appears that all ten of the borings would fall under the hydric classification as
evidenced by the matrix and mottle colors within the upper 12 inches of the column.
6.7 Sediment Transport Analysis
A sediment transport analysis is generally conducted to determine channel stability, morphology and existing
and proposed bedload. Although an active channel is currently present at the Watts Site, the need for
sediment transport was not necessary in the formulation of the design of a headwater, first order stream
system. This design will transport sediment during high events; however, no base channel will be designed.
Therefore, any sediment transport analysis would be considered unreliable based on current designs.
6.8 HEC -RAS Analysis
Section 4.1.7.4 denotes that the UT is situated within FEMA Zone AE, where base flood elevations have been
determined. This classification is based on backwater influence from Little River, its downstream receiving
water. Ecological Engineering developed a HEC -RAS surface water model for the Watts Site to determine the
impacts, if any, the proposed stream and wetland restoration would have on water surface elevations
through the project area. In addition, the analysis was used to ensure that no hydraulic trespass occurred on
adjacent properties. HEC -RAS version 4.0, developed by the USACE, Hydraulic Engineering Center, was the
program utilized to most accurately model the flow of surface waters.
Watts Property Mitigation Plan— Perquimans County, NC Page 33
March 2011

As part of development, Ecological Engineering created an existing model of the Site. Cross sections of the UT
and its floodplain were taken from 150 feet downstream of Norma Drive through the upstream limits of the
Site. The existing 24 -inch CMP under Norma Drive was included in the model. Roughness coefficients, or
Manning's "n" values, were determined for the floodplain and channel sections based on field observations.
The overbank area was determined to exhibit traits resulting in a Manning's "n" of 0.04 and the channel was
determined to be a 0.045. The overbank roughness coefficient was based on former agricultural land in its
current fallow state. The existing vegetation is mostly herbaceous in nature and does not create much
restriction to flow. The channel depicts slightly more roughness than it overbank area since it contains a
minimal amount of woody species.
Once the existing model was developed and calibrated, a proposed model was prepared. The proposed cross
sections show the widening of the stream bed and the flatter sloped banks. Also, Manning's "n" values were
adjusted to mimic the future condition. Overbank Manning's "n" was estimated at 0.15 to reflect the most
dense vegetative growth occurring within five years of construction. The channel Manning's "n" was
estimated at 0.08 to reflect the additional woody and more aquatic species that will occur within the stream
channel. The proposed model also includes the replacement of the 24 -inch CMP with two 36 -inch corrugated
aluminum pipes (CAP) with a headwall.
Ecological Engineering compared the existing and proposed scenarios to ensure no hydraulic trespass would
occur outside the Project Site. Due to the increase conveyance under Norma Drive and the increase flow
capacity of the proposed channel, water surface elevations decreased for all storm events within the project
area and no hydrologic trespass occurs upstream of the project.
The HEC -RAS model output is provided Appendix D.
6.9 Site Construction
6.9.1 Site Grading, Structure Installation and Other Proiect Related Construction
Based on the components itemized in Table 2 of this document, a combination of Coastal Plain Headwater
Forest restoration, Hardwood Flat restoration and enhancement and buffer restoration are proposed as part
of this overall project. The Watts Site is unique in the fact that the entire 48 -acre property will be ecologically
uplifted through community based restoration techniques. Each of these aspects are described in detail. In
addition, the attached Design Sheets provide a visual observation of the existing conditions, proposed
conceptual design and proposed planting plan.
Construction access will occur from the northern boundary of the property along Norma Drive. This road will
afford equipment and material access to the Project Site. Norma Drive is a private road maintained by the
current parcel owners along the roadway. It is expected that the contractor will maintain the road during
construction implementation to ensure that its condition remains consistent with the integrity prior to
implementation. Ecological Engineering recommends the selected contractor thoroughly note and document
existing road conditions prior to mobilization.
Watts Property Mitigation Plan— Perquimans County, NC Page 34
March 2011

Construction activities will likely begin with the replacement of the existing pipe under Norma Drive. It is
currently in very poor condition. Ecological Engineering will prepare designs for the new pipe(s). These
designs will be incorporated with the construction documents. Once the pipe has been replaced, excavation
will begin along the existing side slopes of the UT throughout its length across the property. These side slopes
will be reduced from their existing 60 to 90- degree orientation to a slope averaging approximately 10:1, with
a substantial increase of the base channel width. The excavated material will be used to fill the interior
drainage network. The existing pipes situated along the interior drainage network will be removed in their
entirety. Several pipes exist along the northeastern perimeter that extend outside of the property boundary.
These pipes will be capped to ensure that water removal does not take place. Once excavation along the UT
has been completed, grading will continue outside of this area to reduce the existing field crowns (see
topographic contours on Design Sheet 1), as applicable. This material will be excavated no more than six
inches and directed into the interior drainage network. Any excess will be placed along the eastern portion of
the property, depicted on Design Sheet 3.
Throughout the duration of construction implementation, the Site will be stabilized with erosion and
sedimentation control devices, consistent with the requirements of the NC Sedimentation and Pollution
Control Act of 1973, as regulated by the NCDENR Division of Land Resources, Land Quality Section.
Temporary seeding will occur along all areas of disturbance.
Once construction activities have been completed and approved, the Site will be seeded with a permanent
seed mix and trees will be planted. Several vegetated zones exist based on the current conceptual design.
These zones will be planted with their appropriate mix of vegetation. In addition, larger trees will be
intermixed with bare - rooted seedlings, especially along the project perimeter. These trees will function as
boundary trees and offer an aesthetically pleasing view from areas outside of the property.
6.9.2 Native Plant Community Restoration
6.9.2.1 Soil Preparation and Amendments
Project implementation will involve excavation along the current UT and field crowns between the drainage
ditches and fill along the project boundaries and interior drainage network. During the excavation process,
topsoil will be stockpiled aside from subsoil, where feasible, and utilized as a dressing once the desired
amount of subsoil has been removed. Ripping will not be required since compaction did not likely occur
during past farming operations. Fertilizer and seeding will be distributed per the NC Division of Land Quality's
(NCDLQ) recommended rates, unless the contractor performs a soil test to determine the prescribed
amounts. This soil test may be submitted prior to implementation. Table 3 details soil preparation
methodologies and amendment summaries per vegetated zone.
Herbicide treatments will also be part of the amendment process. Japanese honeysuckle (Lonicera japonica)
exists at the Site. It will be treated along with soil amendment processes. More information pertaining to this
treatment is provided later in the document.

Natural plant community restoration will follow descriptions of community types by NCWAM (2010),
Schafale and Weakley (1990), reference wetland vegetation types and professional judgment. The designed
natural communities are based primarily on landscape position and hydrology. Vegetative restoration will aid
to benefit biological function and habitat. Three distinct vegetative communities are proposed. They are
described in detail below.
The first community follows the existing UT to Little River channel area. It will consist primarily of riparian
wetland vegetation. This community is labeled as "Zone 1" and will depict the characteristics of a Headwater
Forest, as described by NCWAM (2010). Headwater Forest Communities, previously documented as Coastal
Plain Small Stream Swamp Communities by Schafale and Weakley (1990), are found in geomorphic
floodplains or first -order or smaller streams and in topographic crenulations without a stream. Groundwater
seepage and diffuse surface flow are often important sources of water, and this wetland type frequently has
surface flow, especially through ephemeral channels. Overbank flooding is not a substantial source of water
and Headwater Forests are relatively dry when compared to other riparian types. This wetland type is
characterized by a relatively flat ground surface that provides little water storage. Headwater Forests
generally occur on mineral soils that may be intermittently inundated by surface water or seasonally
saturated to semi - permanently saturated (NCWAM, 2010).

The second community, identified as "Zone 2," consists of the non - riparian vegetation situated immediately
outside of the proposed wetland areas at the Project Site. This community is most consistent with the Mesic
Mixed Hardwood Forest, as identified by Schafale and Weakley (1990). Although fire is a necessity for most
Coastal Plain vegetative communities, the Mesic Mixed Hardwood Forest is generally found along upland
areas protected from fire. It is underlain by various moist soils and is generally situated immediately upslope
of Coastal Plain Small Stream Swamp and Non - Riverine Wet Hardwood Communities (Schafale and Weakley,
1990). There are some aspects of this community description that do not fit the characteristics of the Project
Site; however, Schafale and Weakley (1990), identified three recognized variants for the areas located in the
northeastern corner of North Carolina. These included the bluff/ slope variant, upland flat variant and swamp
island variant. Based on current site conditions, the Project Site falls under the upland flat variant, which
transitions into the Non - riverine Wet Hardwood Community and often contains combinations of wetter and
drier species, as well as typical mesic species. Variation may be controlled by small microtopographic
differences (Schafale and Weakley, 1990).
Zone 3, represented as the Hardwood Flat Community, is the third community proposed for the Project Site.
This community will occupy all wetland and transition areas, aside from the area along the existing tributary.
According to NCWAM (2010), Hardwood Flats are found primarily in the Coastal Plain Ecoregion on poorly
drained, interstream flats. These areas are usually seasonally saturated or intermittently to seasonally
inundated by a high water table or poor drainage, but have a shorter hydroperiod than Non - Riverine Swamp
Forests. The primary source of water is a high water table resulting from precipitation and overland runoff. In
their reference state, Hardwood Flats generally occur on mineral soils. These systems are commonly
dominated by hardwood tree species including various oaks including, but not limited to swamp chestnut oak
(Quercus michauxii), laurel oak (Quercus laurifolia) and cherrybark oak (Quercus pagoda), as well as tulip
poplar (Liriodendron tulipifera), sweetgum (Liquidambar styraciflua), American elm (Ulmus americana), red
maple (Acer rubrum) and black gum (Nyssa biflora) (NCWAM, 2010).
6.9.2.3 Planting Plan
The planting plan for the Project Site will provide post- construction erosion control and habitat
enhancement. It will also attempt to blend existing vegetative communities into the recently restored areas.
Plantings in the wetland and buffer areas will include native species appropriate for the Coastal Plain
physiographic province and the Project Site. A variety of trees and shrubs will be planted to provide cover
and habitat for wildlife, as well as soil stabilization.
The Project Site is divided into three vegetated zones. As previously mentioned, these zones were identified
based primarily on landscape position and hydrology. Zone 1, also referred to as the Streamside Area, is
situated along the headwater stream location. This zone will be planted with species similar to the
Headwater Forest, as identified by NCWAM (2010). Zone 2 includes the non - wetland areas and buffer areas
outside of the headwater stream. This zone will be planted with species similar to the Mesic Mixed
Hardwood Forest, as identified by Schafale and Weakley (1990). The remaining areas, depicted as non -
riparian wetlands, are considered Zone 3. Zone 3 will consist of species similar to the Hardwood Flat
Community as described by NCWAM (2010). The proposed planting plan is depicted on Design Sheets 3 and
4. A listing of the preferred species associated with each zone is presented below.

Prior to the planting of trees and shrubs, all disturbed areas associated with the Project Site will be seeded
first with a temporary seed mix. This mix will include either grain rye (Secale cereale), brown -top millet
(Panicum ramosum), or German millet (Setaria italica). The seed material will be selected according to the
time period selected for implementation. Currently, implementation is proposed for the spring of 2012, in
which grain rye would be the preferred seed mix. Table 4 summarizes this data, including time periods and
application rates.

The permanent seed mix will be distributed per vegetated zone. The permanent seed mix will be applied at a
rate of approximately 12 to 15 Ibs per acre, although the individual species will be different in each zone.
Virginia wild rye (Elymus virginicus), autumn bentgrass (Agrostis perennans) and showy tick trefoil
(Desmodium canadense) will be utilized in all three zones. While switchgrass (Panicum virgatum), beggar
ticks (eidens aristosa), coreopsis ( Coreopsis lanceolate), deer tongue (Panicum clandestinum), bushy
bluestem (Andropogon glomeratus), little bluestem (Schizachyrium scoparium), partridge pea (Chamaecrista

The planting of canopy and understory species will dominate Zones 1, 2 and 3. Due to the location and the
flooding regime of the Project Site, the majority of these species must be conducive to periodic flooding.
These species will be planted as bare roots and containerized individuals, with larger individuals placed
randomly throughout the area and especially along the existing non - forested boundaries. Specific species
listings, proposed quantities and other detailed information are provided on Design Sheets 3 and 4.
Vegetation will be planted in a random fashion in an effort to mimic natural plant communities. Colonization
of local herbaceous vegetation will inevitably occur, which will provide additional soil stability. Tree species
will be planted as bare root stock on random eight -foot centers at a frequency of approximately 680 stems
per acre. Understory species will be dispersed among the tree species also on random eight -foot centers.
Containerized plantings will occupy approximately 20 percent of each zone. These plantings will be installed
at a frequency of approximately 320 stems per acre. Planting stock will be culled to remove inferior
specimens, allowing only healthy, viable stock to be planted at the Project Site. Plantings will be dormant and
will be performed to the extent practicable between November 3rd and March 301h.
6.9.2.4 Invasive Species Management
The following list of exotic plant species poses a severe threat to native plant communities in North Carolina
(Table 6). These species have invasive characteristics and spread readily into native plant communities,
displacing native vegetation.

Japanese honeysuckle (Lonicera japonica) was the only invasive species observed during the site visits at the
Project Site. It is situated along the northeastern portion in several isolated areas. It is likely that past farming
operations utilized weed control and the use of herbicide. Although only one invasive species is currently
present, it is anticipated that soil movement from implementation will promote seed growth that is currently
dormant from within the soil column. It is essential that invasive species are documented and controlled
during the monitoring period to ensure that native species are afforded the opportunity to colonize the
Project Site.
The construction contractor will provide removal, as necessary, to any of the species listed above during
construction implementation. Removal will be conducted according to recommended control measures
made through the NC Cooperative Extension Service.
It is anticipated that invasive species management will occur throughout the monitoring period. As seedbeds
and their associated soils are disturbed, it is likely that other invasive species may appear within the Project
Site. Periodical assessments will be conducted to determine if these species are posing a threat to native
population levels. The threats will be determined on an annual basis as well as, their remedial activities, as
necessary.

SECTION 7.0 MAINTENANCE PLAN
EEP shall monitor the site on a regular basis and shall conduct a physical inspection of the Site a minimum of
once per year throughout the post- construction monitoring period until performance standards are met.
These site inspections may identify site components and features that require routine maintenance. Routine
maintenance should be expected most often in the first two years following Site construction and may
include the following items depicted in Table 7.
TABLE 7. MAINTENANCE PLAN
Watts Property Stream and Wetland Restoration Site
EEP Project Number 413
Component/ Feature
Maintenance Through Project Close -Out
Stream
Routine channel maintenance and repair activities may include chinking of in-
stream structures to prevent piping, securing of loose coir matting and
supplemental installations of live stakes and other target vegetation along the
channel. Areas where stormwater and floodplain flows intercept the channel may
also require maintenance to prevent bank failures and head - cutting.
Wetland
Routine wetland maintenance and repair activities may include securing of loose
coir matting and supplemental installations of liver stakes and other target
vegetation within the wetland. Areas where stormwater and floodplain flows
intercept the wetland may also require maintenance to prevent scour.
Vegetation
Vegetation shall be maintained to ensure the health and vigor of the targeted
plant community. Routine vegetation maintenance and repair activities may
include supplemental planting, pruning, mulching and fertilizing. Exotic invasive
plant species shall be controlled by mechanical and /or chemical methods. Any
vegetation control requiring herbicide application will be performed in accordance
with NC Department of Agriculture (NCDA) rules and regulations.
Site Boundary
Site boundaries shall be identified in the filed to ensure clear distinction between
the Mitigation Site and adjacent properties. Boundaries may be identified by
fence, marker, bollard, post, tree - blazing or other means as allowed by site
conditions and /or conservation easement. Boundary markers disturbed, damaged
or destroyed will be repaired and /or replaced on an as needed basis.
Utility Right -of -Way
Utility rights -of -way within the Site may be maintained only as allowed by
Conservation Easement or existing easement, deed restrictions, rights of way or
corridor agreements.

SECTION 8.0 PERFORMANCE STANDARDS
Performance criteria set forth for this project will be provided according to current EEP monitoring criteria
and format. It will cover stream, wetland, and vegetation assessments.
8.1 Streams
Although stream restoration credit is being provided, common perennial -based stream monitoring activities
will not be conducted as part of the annual monitoring assessments. The existing headwater channel will
function to transport surface water; however, it will not maintain the characteristics and morphology of a
perennial channel. Therefore, profile, pattern and substrate monitoring will not be required. Rather,
monitoring activities will be concentrated primarily to observing whether or not the first order system is
stable and functioning similar to the reference sites. The majority of the monitoring will be based on visual
assessments. A Crest gage will be installed to document stream flow. Cross sections will be established along
sections of the valley to document any aggradation or degradation and photographs will be taken from
permanently established locations. These visual assessments, cross section surveys and photographs will be
completed annually. It is anticipated that the actual flow path will migrate across the section from year to
year, depending on flow regimes. The proposed success criteria will be based on the overall performance of
the headwater channel. In addition to aggradation and /or degradation, the channel should not experience
any head - cutting, down - cutting and excessive erosion.
8.2 Wetlands
Both Coastal Plain headwater wetland systems and non - riverine wet hardwood communities exhibit variable
water tables throughout the year. Six monitoring gauges are currently being monitored across the Project
Site to note existing groundwater elevations throughout the area. These gauges have been located
strategically across the site. They will be removed during construction implementation and be returned once
all ground disturbing activities are complete.
Based on the current USACE guidelines for hydrologic success, the area must be either inundated or
saturated within 12 inches of the soil surface by surface or groundwater for at least 12.5% of the growing
season, under normal conditions. The growing season for the area is 246 days. If inundation or saturation is
documented within 12 inches of the soil surface for 31 consecutive days, the Site would meet the hydrologic
success requirement. Any areas inundated or saturated between 5% and 12.5% (12 and 31 days) of the
growing season will be classified as wetlands when hydrophytic vegetation and hydric soils are present.
8.3 Vegetation
The Watts Site will be planted with vegetative species appropriate for the three targeted community types.
The vegetation will be assessed using several variables. The post- construction document will outline these
variables, including plot layout locations, transect locations and /or any other methods pertinent to
determining vegetation success. Stem counts will be conducted within strategically placed vegetation plots.
The plots locations will be determined once implementation has been completed. Photos will also be
provided as part of this task. One this is complete, all information will be summarized with the
stream /wetland assessment information and inserted into the monitoring report.
The vegetation will be monitored on an annual basis. Stem densities that meet 320 stems per acre in the
third year and 260 stems per acre in the fifth year of monitoring will meet the vegetation success
requirement. Vegetation plots will be established for the collection of this data on an annual basis.

9.1 Baseline Monitoring Document
A Baseline Monitoring Document will be prepared to mark the transition from the design /implementation
phase to the monitoring phase. This document along with the As -built record drawings provides a means to
compare the as -built condition to the design specifications and along with the baseline monitoring data
provides a means to assess change /trends during the monitoring period. Many of the tables and components
that originate here in this document will be carried through the monitoring reports and further populated as
the monitoring data is generated (EEP, 2010). According to EEP (2010), the document generally serves
several functions:
Watts Property Mitigation Plan— Perquimans County, NC Page 45
March 2011

• restates the project goals and objectives for stream, vegetation and hydrology components;
• details the project structure in terms of the restoration components /assets;
• provides a synopsis of the project and site background;
• finalizes the success criteria for stream, vegetation and hydrology components;
• finalizes the monitoring plan for stream, vegetation and hydrology components;
• compares the As -built baseline condition to the design specifications for stream, wetland and
vegetation components and encompasses the following:
• sealed As -built plan sheets
• morphological (where necessary) and vegetation data suitable to serve as a
monitoring baseline (year -0); and,
• describes maintenance and repair contingencies.
Although the first three bulleted items may be refined somewhat between the Mitigation Plan and the
Baseline Monitoring Document, in most cases they are simply carried through as they exist in the mitigation
plan. The fourth, fifth and seventh bullets will originate in the Mitigation Plan, but may undergo refinement
between that point and the final Baseline Monitoring Document. Bullet 6 is truly unique to the Baseline
Monitoring Document (EEP, 2010).
9.2 Schedule and Reporting
Schedule and reporting activities for the first year of monitoring will begin once construction implementation
activities have concluded. Initial work, including the establishment of fixed photograph locations, vegetation
plots and channel cross sections, will be completed with regard to future monitoring efforts. Monitoring
gauges will be reinstalled in the same pre- construction locations.
Monitoring reports will be submitted to the regulatory agencies by EEP on an annual basis. The first -year of
monitoring will include two submittals; the As -Built drawings and the First Year Annual Monitoring Report. All
drawings and monitoring will follow EEP protocols established during the project period. It is understood that
EEP will coordinate any necessary monitoring report submittals with the regulatory agencies. If the
monitoring reports indicate any deficiencies in achieving the success criteria on schedule, EEP will coordinate
with the resource agencies, as applicable, to determine the extent of remedial actions necessary. In some
cases EEP may be required to submit remedial action plan, as necessary, as part of the annual monitoring
report. Vegetative monitoring will be conducted during the late summer months of each monitoring year.
Monitoring reports will be provided no later than December 15. The projected schedule provided below is
contingent on completion of Site construction and planting by March 2012.

SECTION 10.0 LONG -TERM MANAGEMENT PLAN
Upon approval for close -out by the Interagency Review Team (IRT), the Site will be transferred to the
NCDENR Division of Natural Resource Planning and Conservation's Stewardship Program (Stewardship
Program). This party shall be responsible for periodic inspection of the Site to ensure that restrictions
required in the conservation easement or the deed restriction document(s) are upheld. Endowment funds
required to uphold easement and deed restrictions shall be negotiated prior to Site transfer to the
responsible party.
The NCDENR Stewardship Program currently houses EEP stewardship endowments within the non - reverting,
interest - bearing Conservation Lands Stewardship Endowment Account. The use of funds from the
Endowment Account is governed by North Carolina General Statute GS 113A- 232(d)(3). Interest gained by
the endowment fund may be used only for the purpose of stewardship, monitoring, stewardship
administration and land transfer costs, if applicable. The NCDENR Stewardship Program intends to manage
the account as a non - wasting endowment. Only interest generated from the endowment funds will be used
to steward the compensatory mitigation sites. Interest funds not used for those purposes will be re- invested
in the Endowment Account to offset losses due to inflation.
SECTION 11.0 ADAPTIVE MANAGEMENT PLAN
Upon completion of Site construction, EEP will implement the post- construction monitoring protocols
previously defined in this document. Project maintenance will be performed as described. If, during the
course of annual monitoring it is determined the Site's ability to achieve Site performance standards are

APPENDIX A
Guidance pertaining to Stream Restoration in the Outer Coastal Plain of North Carolina

INFORMATION REGARDING STREAM RESTORATION IN THE OUTER
COASTAL PLAIN OF NORTH CAROLINA
Prepared By:
US Army Corps of Engineers,
Wilmington District, Regulatory Division
And
North Carolina Department of Environment and Natural Resources,
Division of Water Quality
December 1, 2005
This document is intended to provide information to compensatory mitigation providers
for use when planning or evaluating potential stream mitigation projects in the outer
coastal plain (defined as the Middle Atlantic Coastal Plain Ecoregion as shown on
Griffith, et. al. 2002). This document is meant to complement the April 2003, Stream
Mitigation Guidelines, prepared by the Corps of Engineers Wilmington District,
Environmental Protection Agency, the North Carolina Division of Water Quality and the
North Carolina Wildlife Resources Commission (US Army Corps of Engineers, 2003).
Riparian headwater system are for purpose of this guidance, those systems that either do
not appear or appear as first order streams' on the appropriate county soil survey as
published by the Natural Resources Conservation Service or its predecessor, the Soil
Conservation Service. The term "stream" as used in this guidance, means that the now of
water is contained in a natural channel or bed with identifiable banks and, in its unaltered
state on the coastal plain, usually has adjacent wetlands.
The majority of compensatory stream mitigation completed to date in North Carolina has
been in the Piedmont and Mountain Regions. Mitigation site selection efforts in these
areas target degraded sites where the main problems are instability and unnatural
sediment transport. Maximum mitigation credits are achieved by using natural channel
design techniques to return the stream to its most probable natural state by restoring
proper pattern, dimension and profile.
Many outer coastal plain riparian headwater systems have been channelized or ditched in
the past, making it difficult to determine whether a true intermittent or perennial stream
was historically present. These existing "man- made" channels have, in most cases,
intercepted surface runoff and /or groundwater to the extent that they now possess
intermittent or perennial flow and exhibit functions commonly associated with natural
streams. These systems are often considered jurisdictional waters of the US and, in many
cases, are classified as "streams ". Permits to impact these systems usually require some
form of stream mitigation as compensation.
' A first order stream is that portion of a waterway from its identified point of origin downstream to the first
intersection with another waterway.

There is an increasing need for compensatory stream mitigation in the outer coastal plain
of North Carolina. Many sites selected to provide compensatory mitigation are
channelized or ditched riparian headwater systems. There is debate over the necessity
and /or appropriateness of traditional channel design techniques in these systems.
Typically, intermittent and perennial streams with well - defined bed and bank
characteristics are associated with specific soil series (Table 1) and are present in those
unaltered riparian headwater systems having relatively large watersheds draining into a
well- defined topographic feature. Here, natural channel design techniques may be
appropriate.
Often however, unaltered riparian headwater systems with smaller watersheds and less
definite topography possess a braided, diffuse flow pattern across a narrow floodplain of
riparian, wooded wetlands. In these instances, stream restoration involving the
development of pattern, dimension, and profile would not be appropriate. These sites
would likely not support engineered stream channels due to the lack of slope and sandy
terrain. Restoration of these riparian headwater systems could still be accomplished to
provide both stream and wetland mitigation credit without physically constructing a
distinctive stream channel.
The NCDWQ is currently working with researchers from NC State University and the
N.C. Center for Geographic Information and Analysis to develop a stream mapping
methodology. This methodology should provide scientifically valid predictions for the
origin of coastal plain streams. However, it is likely that it will be several years before
this data is available. In the interim, those involved in the development of compensatory
stream mitigation projects on the outer coastal plain of NC should use the following
criteria to decide what design is appropriate for the proposed mitigation site.
Zero to first order headwater streams: Restoration of stream pattern, dimension and
profile is often not appropriate in features appearing as zero to first order, headwater
streams in the outer coastal plain. Projects constructed in these areas may still qualify for
stream restoration even though they may not include construction of an actual channel.
These projects should include success criteria commensurate with the restoration of a
bottomland riparian (wetland) community. Additional considerations for success criteria
may include documentation of diffuse flow and inundation of adjacent wetland. Credit
will be calculated based on the length of the valley rather than an exact length of the
channel.
The limit of credit for stream and riparian wetland mitigation credit will be decided on a
case -by -case basis and will typically depend on the width and extent of a clearly visible
valley in the landscape. A 50 -foot buffer is typically required for stream mitigation
projects in the coastal plain. Therefore, stream credit may only be awarded where the
discernible valley is a minimum of 100 feet wide. Areas outside this 100 foot corridor
but within the valley feature may be used as riparian wetland mitigation. The width of
the valley would usually be defined using the edge of the valley slope. Mitigation outside
For the purposes of this guidance, jurisdictional waterways that do not appear on a county Soil Survey are
considered zero order
01

of and /or above this valley could be considered non - riparian wetland mitigation assuming
restoration of wetland hydrology, hydric soils and appropriate wetland plants. In -field
confirmation of the presence and limits of the valley may be needed in order to determine
the extent of riparian wetland and stream mitigation. Local topographic information
(USGS quad sheets, LIDAR imaging, site - specific topographic surveys, etc.), site -
specific soil mapping (for instance, linear mucky soil features bordered by mineral soils)
and information on flood frequency and duration are often helpful tools in identifying
these valleys in the outer coastal plain.
Second and higher order streams: Traditional stream mitigation methods using natural
channel design to predict and restore pattern, dimension and profile are typically
appropriate in systems indicated as second and higher order streams. Credit for this type
project would be calculated based on the actual length of the channel restored or
enhanced. The restoration of wetlands adjacent to the restored channel should be given
strong consideration.
This document is intended as a general guide. The preparers realize there may be
exceptions to the above information. Natural channel design may, for instance, be
appropriate when a zero or first order stream is located in a soil series that traditionally
supports streams (Table 1) and sufficient watershed area is available. The converse is
also true in that there may be larger watersheds where stream mitigation as described for
zero to first order streams may be more appropriate. It is also likely that large mitigation
sites may have both zero /first order streams and higher order streams as well as wetland
complexes thereby requiring multiple mitigation design techniques. Designers are
strongly encouraged, in all cases, to use reference sites with similar watershed size and
topographic conditions to determine the type of restoration that is appropriate for the site
Planning documents must adequately support the mitigation work proposed.
The guidance found in this document is subject to change if and when additional
information becomes available. The most current version of this document as well as
information on its applicability will be posted on the websites of both the Corps of
Engineers (http: / /www.saw.usace.anny.mil /wetlands /notices.html) and Division of Water
Quality ( http: / /h2o .enr.state.nc.us /ncwetlands /rd pub_not.html).

Groundwater Modeling/ Hydrologic Budget
Methodology and Input Data
Development of the water budget follows equations presented in the Engineering Field
Handbook (USDA, 1997). The following equations were used to determine the inflow, outflow
and water available for storage on -site.
AS /At = Q; - Qo

Water Storage
The following chart depicts the calculated water storage available at the Project Site.
Water Storage
Soil Type Depth (in) Average Water Capacity Storage Capacity (ft)
(in /in) (depth) * (ca pacity) *(area)
Roanoke 0 -8 0.17 236,595.5
8 -36 0.175 851,743.6
Total 1,088,339
Data obtained from Soil Survey of Perquimans County
Using a storage depth of three feet, and a surface area of 2,087,604 square feet, a total
subsurface storage capacity of 1,088,339 ft3 was calculated. It is anticipated that minimal or no
surface water (ponding) will occupy the wetland areas, with exception of the channel flowing
through the Site. Due to the Site constraints, a conservative estimate of no surface water was
made for calculation purposes.
Inflow
Precipitation
The average annual precipitation over the last 30 years was 48.2 inches, per the State Climate Office as
recorded in Elizabeth City. Over the square footage of the property, a volume of 8,385,209 ft3 of rainfall was
calculated.
Stormwater Runoff
To simplify calculations and to be more conservative, stormwater inputs are assumed to be zero
Base Flow
Base flow is assumed to be zero.
Groundwater Flow
Due to a perimeter ditch that circumvents the project site and extensive draining of adjacent properties,
zero groundwater inflow is assumed for conservative calculation purposes.
Artificially Added Water
There is no water artificially added to the Project Site.

Tidal Flow
The water level in the wetlands is not influenced by tidal flows.
Outflow
Evapotranspiration (E + T)
The loss of water due to evaporation and transpiration (ET) was calculated using the Thornthwaite Method.
Temperature data was obtained from the State Climate Office Website, Elizabeth City Station.
ET = 1.6 *(10 *Ta / I)a
Where: ET = Evapotranspiration
Ta = mean monthly air temperature ( °C)
I = heat index over 12 months
a = 0.49 + 0.0179 *1 - 0.0000771 *1Z + 0.000000675 *13
I = sum of 12 i values
i = (Ta / 5 )1.514
Where: i = monthly heat index
Ta = mean monthly air temperature ( °C)
Water loss due to evapotranspiration is 30.93 inches per year (5,338,011 ft3 /year) due to a heat
index of 77.61. The value of "a" calculates to 1.730.
Stormwater Runoff
To simplify calculations and to be more conservative, stormwater outputs are assumed to be zero.
Base Flow
Base flow is assumed to be zero.

Groundwater flow exiting the project site was calculated from an equation presented in Applied Hydrology,
Third Edition.
Vx = ( K / ne ) * (dh /dl
Where: Vx = ground water velocity
K = hydraulic conductivity of the soil
ne = soil porosity
dh /dl = change in vertical distance over change in horizontal
distance
The Watts property is underlain predominately by Roanoke silty loam. This soil type exhibits a K
of 25 mm /hr and ne of 43% up to a depth of eight inches. From eight to 36 inches the K is 8
mm /hr and ne is 49 %. For a conservative calculation, K of 25 and ne of 43% was used for the
entire three foot depth studied. A volume of 11,530 ft3 /year was calculated to leave the site via
groundwater flow.
Artificially Added Water
There is no water artificially removed from the Project Site.
Tidal Flow
The water level in the wetlands is not influenced by tidal flows.

The water budget results verify the presence of adequate water to meet the proposed wetland
hydrology criteria for the majority of the Project Site. Calculations indicate excess water when
comparing inflow to outflow and by assuming that base channel flow and stormwater flow were
zero, these calculations present a conservative estimate of available water.

APPENDIX E
Reference Site Analyses

REFERENCE SITE ANALYSES
Ecological Engineering utilized several sources of existing reference information approved by EEP and the
regulatory agencies as part of the reference assessment for the proposed design. Information was obtained
from EEP, which recently implemented a similar Coastal Plain headwater stream restoration project
approximately 24 miles west of the Watts Site. In addition, previous work was completed for the Watts Site
under a pretense for natural channel design -based stream restoration. This work included a limited
assessment of potential wetland reference areas for riverine and non - riverine wetland restoration. Both
reference assessments were conducted by consultants under contract with EEP. Ecological Engineering also
qualitatively viewed the property immediately west of the Watts Site. Permission to conduct surveys was not
granted. Therefore, only visual surveys were recorded from the property boundary separating the Project
Site from this area. Photographs of the reference wetland sites are depicted later in this appendix.
Since data from multiple reference sites was available, a holistic approach was used to formulate the
conceptual design. More emphasis however, was associated with the data from Reference Wetland Sites 1
through 4 rather than Sites 5 and 6. This reasoning was based on raw data availability and confidence.
Target Reference Conditions
The Watts Site is currently fallow. It is drained via a network of linear and lateral drainages. Other than the
soil characterization, there is little evidence of the historical wetlands that would have existed on the site. As
a result, Ecological Engineering utilized physical parameters as well as other reference materials to ascertain
the target wetland types. The physical parameters included watershed size, soil mapping units and general
topography. Reference materials included information on vegetation community types.
According to EEP (2006), the following conditions summarized the search for a suitable Coastal Plain
headwater stream and wetland reference (Headwater Forest) site:
• location within the Outer Coastal Plain physiographic region;
• minimal hydrologic alteration;
• jurisdictional wetland status;
• watershed size between 30 and 300 acres (with the three sites spanning the range);
• climax community — Headwater Forest (Small Stream Swamp) or Hardwood Flat (Non - Riverine
Wet Hardwood Forest);
• similar watershed soil types;
• similar site soil types;
• minimal impervious surfaces within watershed;
• similar topography; and,
• minimal presence of invasive species.
Reference Site Search Methodology
According to EEP (2006), all of the parameters listed in the above section were used to find three appropriate
reference sites. A GIS -based search was initially conducted for the identification of reference wetland sites in
the Outer Coastal Plain. The GIS process was first based on an automated procedure which included the
overlay of CAMA wetland data, Chowan Soil Data, NC Gap Analysis Project (NCGAP) data, and public land. No
eligible sites were found on public land. After potential sites were identified, sites near the project area were
manually reviewed using other available GIS data such as aerial photography and topography. Once sites
Watts Property Mitigation Plan— Perquimans County, NC Appendix z
March 2011

were identified, some were visited that could be easily viewed from public roads. Neither Chowan County
nor Edenton have GIS based parcel data; therefore, candidate reference site information was acquired at the
Chowan County Tax office and Register of Deeds office (EEP, 2006).
In 2003, Hurricane Isabelle impacted the northeastern portion of North Carolina and caused localized
damage. This storm knocked down many trees. Even more trees were taken down as the landowners
undertook clearcut operations in an effort to salvage available timber and reduce fire hazards. Several
potential reference sites identified during the reference site search suffered tree loss from Hurricane Isabelle
and were subsequently clearcut (EEP, 2006). Three reference sites were located during this search. The first,
adjacent to EEP's UT to Pembroke Creek headwater stream restoration project site, and two within 20 miles
of the Watts Site. All three reference sites are situated within Chowan County and may require permission
from the landowner prior to entry. The fourth site is adjacent to the Watts Site in Perquimans County. Sites 5
and 6 were ascertained from previous work done at the Watts Site in 2005. These two sites are located
approximately three miles northwest of the Project Site in Perquimans County.
The following table shows a general assessment of each reference wetland as they relate to the parameters
laid out above.

Reference Site Parameters
Wetland determination forms were completed for the first three reference wetland sites. Copies of these
forms are provided later in the appendix. Each reference wetland exhibits two forms, one from within the
wetland boundary and one from outside the boundary.
Reference Wetland 1
Reference Wetland 1 is situated approximately 3.5 miles northwest of Edenton and adjacent to the UT to
Pembroke Creek Restoration Site (Appendix E - Figure 5). According to EEP (2006), several parameters were
collected during the reference reach surveys to better understand the physical setting of the reference area
and to integrate the collected parameters into the restoration design. Reference wetland cross sections were
Watts Property Mitigation Plan— Perquimans County, NC Appendix C L
March 2011

surveyed and are provided at the end of the appendix. The drainage area for Reference Wetland 1 is
approximately 45 acres and significant ponded and flowing water was evident during the survey. Average
land slope down the wetland valley was 0.5% and water surface slope was 0.2 %. The flat portion of Cross
Section 1 was 143 feet
long and 58% of the distance was wet or had standing water. The flat portion of Cross Section 2 was 133 feet
long and 76% of the distance was wet or standing water. Reference Wetland 1 is located in a former Carolina
Bay and a significant portion of its upstream watershed was a former sandpit. Accordingly, a large portion of
the watershed has the soil designation Udorthents, indicating an area where natural soil has been altered
(EEP, 2006).
Soil Characterization
According to EEP (2006), soil borings were conducted within Reference Wetland 1. The wetland soils were
determined as Cape Fear loam bordered by Roanoke silt loam. Cape Fear loam is described as very poorly
drained, nearly level soils on stream terraces. These soils formed in alluvial sediment. A seasonal high water
table is at or near the surface. In a typical profile, the surface layer is black and very dark gray loam about 14
inches thick. The subsoil, about 26 inches thick is dominantly gray, firm clay mottled with yellowish brown.
Below the subsoil and extending to a depth of about 60 inches is light -gray coarse sand mottled with gray.
Natural fertility, the content of organic matter, and available water capacity are all medium. Permeability is
slow, and shrink -swell potential is high. In areas that have not received lime, reaction is very strongly acid. Its
taxonomic classification is fine, mixed, semiactive, thermic typic umbraquults. Soil maps and aerial
photographs are presented in Appendix E - Figures 6 and 7, respectively.
The following chart depicts the typical soil description for Reference Wetland 1.

Vegetation
According to EEP (2006), Reference Wetland 1 was in fairly good condition for vegetation analysis. However,
many trees had been knocked over from Hurricane Isabelle and the transition area had a fairly high number

Reference Wetland 2
Reference Wetland 2 is situated approximately eight miles east of Edenton (Appendix E - Figure 8). According
to EEP (2006), the drainage area for Reference Wetland 2 was approximately 279 acres. Average land and
water surface slopes along the wetland valley was 0.5 %. The flat portion of Cross Section 1 was 133 feet long
and 53% of the distance was wet or had standing water. The flat portion of Cross Section 2 was 87 feet long
and 28% of the distance was wet or standing water (EEP, 2006). These cross sections are depicted in at the
end of the appendix.
Soil Characterization
According to EEP (2006), the site soil series for Reference Wetland 2 is Chowan silt loam (Appendix E - Figure
9). Reference Wetland 2 is very wet, but it does not have a defined stream channel. Therefore, this is
reflected in the proposed restoration efforts as no defined stream channel is proposed (EEP, 2006). Soil
borings were conducted within Reference Wetland 2. The taxonomic classification for Chowan silt loam is

Vegetation
According to EEP (2006), the canopy of Reference Wetland 2 was impacted by Hurricane Isabelle. However,
all of the plant species are still represented, just present at lower densities. An aerial photograph is
presented in Appendix E - Figure 10. Overall, Reference Wetland 2 appeared to be very representative of the
Coastal Plain Small Stream Swamp and the Mesic Mixed Hardwood Forest community type (EEP, 2006).

Reference Wetland 3 is also located approximately eight miles east of Edenton. It is approximately one mile
north of Reference Wetland 2 (Appendix E - Figure 8). According to EEP (2006), the drainage area for
Reference Wetland 3 was 30 acres and had the appearance of being slightly drier than Reference Wetland 2
with no standing water. Small channels were evident at the lower end of the reference. Average land surface
slope along the wetland valley was 1.6 %. Assuming flow in the observed channels, a range for valley width of
14 to 47 feet for this reference (EEP, 2006).

Soil Characterization
According to EEP (2006), Soil borings were conducted within Reference Wetland 3. The wetland soils were
found to be Roanoke silt loam (Appendix E - Figure 11). The following is the typical soil description for
Reference Wetland 3 (EEP, 2006).

Vegetation
According to EEP (2006), Reference Wetland 3 is a younger forest than the other two reference wetland sites.
This appears to have helped save the trees as they were more protected during Hurricane Isabelle. Even
though it was younger, it still has an enclosed canopy and no real invasive species problems. An aerial
photograph is provided in Appendix E - Figure 12.

Reference Wetland 4 is situated immediately adjacent to the Project Site (Appendix E - Figure 13).
Specifically, it is located adjacent to the western boundary and supports a stable Headwater Forest
community. Property access was denied by the landowner; however, a visual reconnaissance was completed
by walking along the property boundary. This visual reconnaissance along with a detailed map review
provided the following information regarding this reference site.
Watts Property Mitigation Plan— Perquimans County, NC Appendix E -Page 6
March 2011

Reference Wetland 4 exhibits an overall drainage area of approximately 60 acres. One small channel was
observed with standing water throughout its length. Its immediate watershed is mostly forested surrounded
by network of agricultural lands. The vegetation within this area is mature and likely greater than 50 years in
age. Its understory is relatively sparse allowing for visual investigations to take place.
Soil Characterization
The following soil information is based exclusively on a literature and map review. As previously mentioned,
access to this area was not granted. According to NRCS (2010), Reference Site 4 is underlain primarily by
Roanoke silt loam (Appendix E - Figure 14). Dogue fine sandy loam and Dorovan muck also exist, but are
situated near the site's downstream confluence with the Little River. The taxonomic classifications for
Roanoke and Dogue soils are presented in Section 6.6. The taxonomic classification for Dorovan muck is
dysic, thermic typic haplosaprists (NRCS, 2010).

Vegetation
Based on visual investigations of the reference area, a mature forest is present. Storm damage is obvious by
the gaps in the canopy, as well as evidence of downed trees. However, this damage does not seem to have
adversely effected the current type. An aerial photograph of the area is presented in Appendix E - Figure 15.
Vegetative species observed are presented below. Actual percentages and/ or dominance assessments were
not conducted since access to the property was restricted.

Reference Wetland 5
According to EEP (2005), this wetland area is located approximately three miles northwest of the Watts Site
(Appendix E - Figure 16). Specifically, it is east of Red Bank Road (SR 1331) approximately one mile north of its
intersection with Woodville Road (SR 1329). This wetland site was identified as riverine. Based on the
information available, its underlying soils are mapped as Chowan silt loam (Appendix E - Figure 17). This soil
is very poorly drained and present along the floodplains of small streams that flow into the Perquimans River
(EEP, 2005).
The canopy is dominated red maple (Acer rubrum), green ash (Fraxinus pennsylvanica) and American elm
(Ulmus Americana). According to the document, it was evident that approximately 60 to 80% of the canopy
was damaged by the hurricanes that struck the area in 2004. The shrub stratum included Chinese privet
(Ligustrum sinense), Japanese honeysuckle (Lonicera japonica), greenbrier (Smilax spp.), rattan vine
(Berchemia scandens) and various saplings from the species noted in the tree stratum (EEP, 2005). The
document also notes the manipulation of this site has occurred in the past, and the consultant recognized
that the reference vegetation lacks diversity (EEP, 2005). An aerial photograph of the reference area is
provided in Appendix E - Figure 18 and site photographs are also available in this appendix.
During March 2005, the consultant reportedly installed two gauges within this reference area to collect
groundwater data. These gauges were identified as WRR -1 and WRR -2. No data was available for these
gauges and it is unsure whether or not these gauges are still in place.
Ecological Engineering presented this information since it was available and associated with prior work at the
Project Site. Overall, the existing data was lacking in quantitative information and not utilized as a main
background source for the conceptual design.
Reference Wetland 6
In addition to Reference Wetland 5, the consultant also located and assessed a nearby non - riverine wetland
reference site. This site, referred to as Reference Wetland 6 is also located east of SR 1331 and approximately
three - fourths of a mile west - northwest of its intersection with SR 1329 (Appendix E - Figure 16). According to
EEP (2005), the area appears to flood much less frequently than the riverine reference wetland (Reference
Wetland 5) and although no areas of standing water were observed, soils were saturated to near the ground

surface. These soils were mapped as Tomotley fine sandy loam, a poorly drained soil with moderate
permeability (EEP, 2005).
The canopy was dominated by loblolly pine (Pinus taeda) with limited specimens of tulip poplar (Liriodendron
tulipifera), red maple (Acer rubrum) and an unidentified oak (EEP, 2005). The shrub stratum consists of wax
myrtle (Morelia cerifera), sweetgum (Liquidambar styraciflua), American holly (Ilex opaca), greenbrier (Smilax
spp.) and saplings of species noted in the canopy. An aerial photograph of this area is depicted on Appendix E
- Figure 18 and site photographs are also provided in the appendix.
Ecological Engineering also presented this information since it was available and associated with prior work
at the Project Site. Overall, the existing data was lacking in quantitative information and not utilized as a
main background source for the conceptual design.
During March 2005, the consultant also reportedly installed two gauges within this reference area to collect
groundwater data. These gauges were identified as WRN -1 and WRN -2. No data was available for these
gauges and it is unsure whether or not these gauges are still in place.
