BRICE CREEK WETLAND MITIGATION BANK
BANK PROSPECTUS
INTRODUCTION
A. Project Overview
The proposed mitigation bank site (approximately 617 acres) consists predominantly of former headwater
wetlands that drain to Great Branch (a first-order tributary of the Trent River), Tucker Creek (a first-order
tributary of the Neuse River), and the East Prong (a first-order tributary of the Trent River). Non-riparian
wetlands have been historically ditched and managed on the tract for silvicultural production. A network of
drainage ditches on the tract serve to lower groundwater tables and intercept surface water. Flow is
diverted into the East Prong that drains to Brice Creek and subsequently into the Trent and Neuse Rivers.
Based upon preliminary site investigations, approximately 554 acres of non-riparian wetland restoration may
be viable on the tract.
The site consists entirely of drained hydric soils characteristic of broad interstream flats of the outer Coastal
Plain. Representative mapped soil units include Bayboro mucky loam, Pantego fine sandy loam, Rains fine
sandy loam, and Leaf silt loam. These series are poorly drained to very poorly drained soils characteristic of
nonriverine wetlands. Open ditching on approximate 330-ft spacing for timber management has effectively
lowered water table levels throughout a majority of the site, effectively removing wetland hydrology. This is
supported by observed field indicators, groundwater monitoring data, and DRAINMOD studies.
Assuming a 125-ft setback for boundary ditches to be left in their present condition (to minimize hydrologic
trespass), the tract offers up to 554 ac +/- of potential for nonriverine wetland restoration, enhancement, and
preservation. Given the landscape position and soil types occurring on the tract, we believe that the entire
site formerly consisted of nonriverine wet hardwood flats. Based upon the proposed mitigation effect, the
bank site will result in 497 non-riparian wetland credits (restoration equivalent credits). Supply of these
credits to Section 404/401 applicants will be deemed as suitable mitigation to offset authorized wetland
impacts in the identified Geographic Service Area (GSA).
B. Site Location
The tract is located south of Highway 70 (between New Bern and Havelock) and just east of Catfish Lake
Road in Craven County, NC. It is bordered on the south by East Prong, a first-order tributary of the Trent
River. Refer to the enclosed site location map (Figure 1), USGS topographic quadrangle (Figure 2-3), and
the Craven County Soil Survey map (Figure 4) for additional site information. A 1998 infra-red aerial

photograph of the site (Figures 5) is also enclosed for reference.
C. Project Purpose and Service Area
The Brice Creek tract is located within the Middle Atlantic Coastal Plain (Ecoregion 63) as defined by Griffith
et al. (2002) "Ecoregions of North Carolina" (refer to Appendix A). This ecoregion encompasses the area
defined as the `Carolina Flatwoods' - a subregion occurring along nearly level, poorly drained areas in the
outer Coastal Plain including the lower Neuse River Basin and the White Oak River Basin.
The "Ecoregions of North Carolina" is a collaborative effort between the NRCS, EPA, NCDENR, U.S.
Geological Service (USGS), U.S. Forestry Service (USFS), and the University of North Carolina (UNC). The
Ecoregions Project has identified areas of North Carolina consisting of ecosystems that are similar in type,
quantity, and quality of environmental resources. Characteristics of ecoregions include similar geology,
physiography, vegetation, climate, soils, land use, wildlife, and hydrology.
The Geographic Service Area (GSA) is the designated area wherein a bank can be reasonably be expected
to provide appropriate compensation for impacts to similar wetland and/or other stream or aquatic functions.
Since the Brice Creek site is in close proximity to the White Oak River Basin and will restore similar habitat,
the GSA includes a subset of 14-digit HUCs occurring within the vicinity of the site. The GSA is inclusive of
the 14-digit watersheds listed in Table 1. Refer to Figure 6 for the location and extent of the GSA.
The proposed project will serve as a general use wetland mitigation bank serving the Lower Neuse River
Basin (USGS 8-digit hydrologic unit 03020204) and adjoining 14-digit HUCs of the White Oak River Basin.
The purpose of the bank is to compensate for those wetland losses authorized by applicable federal and
state regulatory programs via the restoration, enhancement, and preservation of approximately 554 acres of
wetlands (See Figure 8).
BASELINE CONDITIONS
A. Community Types
The tract consists of former wetland hardwood flats with characteristic mineral soils, topography, and
drainage patterns consistent with interstream divide systems. The primary wetland type targeted for
restoration are nonriverine wet hardwood flats. Based upon the Cowardin classification for wetland and
deepwater habitats (Cowardin et al. 1979), the primary wetland community type to be restored is Palustrine
Forested Wetland (broad-leaved deciduous, needle-leaved deciduous and broad-leaved evergreen).

B. Vegetation
The predominant land use of the tract and surrounding area is silvicultural production. Dominant wetland
vegetation of the tract includes species such as loblolly pine (Pinus taeda), red maple (Acer rubrum), and
sweet gum (Liquidambar styraciflua). Nearly all the former wetland habitat on the tract has been drained
and managed for timber production. At the time of preliminary site investigations, the southwestern portion

of the site had been recently clear-cut, while significant acreage remained planted with loblolly pine in
various stages of growth. Existing wetland areas exhibit greater densities of bay species including red bay
(Persea palustris), sweet bay (Magnolia virginiana), loblolly bay (Gordonia lasianthus), Other commonly
occurring species in undrained portions of the tract include catbrier (Smilax species), red maple, fetterbush
(Lyonia lucida), bitter gallberry (Ilex glabra) and, titi (Cyrilla racemiflora). Netted chain fern (Woodwardia
areolata), and cinnamon fern (Osmunda cinnamomea) are common herbaceous species of these areas.
Brice Creek Wetland Mitigation Bank Prospectus 3
Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
Drained wetland areas (suitable for restoration) exhibit a mix of species indicative of changes in hydrology.
Remnant wetland canopy species (e.g. red maple) tend to persist in certain areas. However, subcanopy
species and herbaceous vegetation is indicative of drier conditions resulting from site drainage. These
species include water oak (Quercus nigra), yellow jasmine (Gelsimium sempervirens), horse sugar
(Symplocos tinctoria), bracken fern (Pteridium aquilinum), and dog fennel (Eupatorium capillifolium).
C. Soil Characteristics
The tract (located within the headwaters of Brice Creek and Tucker Creek) exhibits nearly level to gently
sloping topography. The site and surrounding area is grouped in the Pantego-Bayboro-Rains-Leaf general
soil unit. This assemblage is characterized by nearly level, very poorly drained soils that have silt and muck
surfaces and are subject to rare to frequent flooding. The predominant wetland soil units occurring on the
tract are the Pantego fine sandy loam and Bayboro mucky loam soil series. These soils occur on broad flats
and/or depressions and are very poorly drained (refer to Figure 4). Each of these soil units is characterized
by low chroma (black or dark brown), often mucky surfaces. The Pantego series has a black fine sandy
loam surface layer to approximately 15" and is underlain by a dark gray sandy clay loam. The Bayboro
series consists of organic muck to approximately 13" and is underlain by grayish brown loam to
approximately 17", and is underlain by grayish brown clay loam and grey clay. Other wetland soil units on
the tract include Rains fine sandy loam and Leaf silt loam. These are poorly to very poorly drained soils
occurring in low flats and in depressions of uplands.
D. Hydrology/Hydraulic Characteristics
The tract is located within a headwater area that has been historically managed for timber production. An
intensive drainage network (of varying ditch size) effectively drains most of the former nonriverine wetlands
occurring on the property. Drained hydric soils (i.e. low-chroma, friable soils exhibiting a relatively high
percentage of uncoated sand grains) are clearly evident along either side of existing ditches on the tract.
Subsidence around old-growth trees and oxidation of surficial organics are also indications of long-term
drainage. Given the predominant soil type on the tract and observed field indicators, the lateral drainage
effect of the ditches is estimated to be approximately 200 to 300 ft for many of the ditches occurring on the
property. Beyond these distances, drainage appears to be restricted. Estimates of lateral drainage
distances are consistent with those values observed in other drained sites with soil groups exhibiting similar
hydraulic conductivity and drainable porosity.
Thirty-two (32) automated wells were installed on the site to document existing groundwater hydrology.
Brice Creek Wetland Mitigation Bank Prospectus 4
Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
Nearly all of these wells have indicated relatively rapid discharge subsequent to rainfall events. Existing
data from the early growing season of 2007 (March through May) were used to calibrate DRAINMOD
software. DRAINMOD was used to model the drainage effect of the existing ditch network for a period of
30 years (1959-1989). A total of four (4) models were developed using well data from each major soil type
found within the project area (Appendix B).
Calibration of each model is based on observed water table and precipitation data. During calibration a
variety of inputs such as drain depth and drain spacing are adjusted to generate a calculated response to
precipitation events. Results from this calibration are displayed in graphical format, plotting actual water
table depths in relation to model results. Once these two data sets are synchronized, a statistical analysis is
completed to ensure that a best fit has been achieved. Current state statutes require a statistical difference
of less than 6 inches between the two. This statute was applied to the model developed for this project.
Wells #25, 28, 5, and 8 were modeled using DRAINMOD. Wells 5 and 28 were located in the Bayboro soil
unit. Well 8 was located in the Rains unit while Well 25 was placed in the Pantego unit. In addition to
representing each of the major soil types found on-site, these wells also characterize the geography of the
site. Modeling results for Well 28 found the area to be effectively drained as it failed to meet the wetland
hydrology criteria in each of the 30 years. Well 25 showed similar results, meeting the criteria in one of the
30 years. The remaining wells met the criteria in 9 of the 30 years. Overall, model results depict an area
that has been effectively drained through historically prescribed drainage improvements.
III. CONCEPTUAL PLAN
Hydrology Restoration: The proposed mitigation bank includes the restoration of up to 475 ac of nonriverine
wetland habitat via the backfilling and/or plugging of ditches. In addition, removal of a portion of the
roadbeds will allow for surface water to sheetflow along its natural gradient. Installation of ditch plugs and
associated grading work along secondary and tertiary ditches will restore characteristic wetland hydrology to
wet hardwood areas. Based upon preliminary site investigations, some boundary ditches will be left intact to
prevent hydrologic trespass. Future topographic survey work and additional drainage evaluations will help
to determine the specific limits of the restoration work. The estimated acreage for the project area (560 ac)
assumes a 125-ft offset from all property boundaries. Refer to Figure 7 for a conceptual plan map depicting
proposed areas of restoration.

Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
Vegetation Restoration: Drained wetland areas that have been cleared will be planted with characteristic
wetland species. Depending upon landscape position and soil type, suitable species may include swamp
chestnut oak (Quercus michauxii), tulip poplar (Liriodendron tulipifera), willow oak (Quercus phellos), and
black gum (Nyssa biflora). Areas of deeper organic soils may also include plantings of water tupelo, Atlantic
white cedar and bald cypress. Tree seedlings will be planted on 10-ft spacings (equivalent to a density of
435 stems/acre). Shrub species will be planted on 8-ft spacings (equivalent to a density of 680 stems per
acre). Other characteristic shrub species (e.g. inkberry, fetterbush, American titi) will continue to volunteer
aggressively into the restored wetland areas.
Functional Restoration: Restored wetlands will intercept runoff from adjacent parcels, dissipate stormwater
velocity, and enhance nutrient and sediment trapping. These restored functions are likely to have
discernible benefits to water quality and habitat downstream. Vegetative restoration will provide for
increased foraging and refuge habitat for resident and migratory species. In light of acute development
pressures in this region of eastern North Carolina, the Lower Neuse River and White Oak River Basins are
particularly susceptible to loss of wetland functions and associated watershed impacts. By providing for
successful restoration of an expansive nonriverine wetland system, the mitigation bank will help to replace
wetland functions critical to water quality and wildlife habitat in the area.
Earthwork/Site Preparation: Initially, all remaining loblolly pine stands will be logged to allow for hardwood
plantings to commence. Backfilling and/or installation of ditch plugs will follow the logging activities. Where
possible, existing spoil piles and logging roads will be used to source the material for this portion of the
earthwork. Clay plugs will also be used in former ditch outlet areas to promote hydrologic restoration.
Prior to placing fill material in any of the existing ditches, a Nationwide (#27) permit will be prepared and
submitted to NC Division of Water Quality and US Army Corps of Engineers. As total disturbance will
exceed 1 acre, a sediment and erosion control plan will also be filed with NC Division of Land Quality. The
erosion control plan will likely include provisions for installation of check dams and silt fencing to prevent
sedimentation of down-gradient waters.
Wetland Enhancement: Wetland enhancement is targeted for approximately 23 acres of the project site
(Figure 7). The areas were targeted due to their location outside of the drainage effect. Areas targeted for
restoration were based on a 150' lateral drainage effect from each ditch. In order to establish the acreage
for the enhancement, an additional 150' offset was placed on the isolated ditches along the perimeter of the
site.
Brice Creek Wetland Mitigation Bank Prospectus 6
Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
Prior to any clearing activities, a survey of the existing vegetation in each of the four areas will be conducted
to determine if there is a sufficient number of target species (swamp chestnut oak, tulip poplar, etc.) present.
In the event that these areas are determined to be dominated by non-target species, logging and clearing
will be initiated. Following clearing activities, planting will take place using same species and spacing
criteria planned for the restoration areas.
Wetland Preservation: Four areas, totaling 56 acres have been targeted for wetland preservation within the
site (Figure 7). The preservation area consists of relatively undisturbed jurisdictional wetlands along the
perimeter of the site. Wetland hydrology of these areas remains unaltered by drainage features of the site,
as they are located greater than 300' from any existing ditch. As such, these wetlands exhibit seasonal
saturation and inundation characteristic of natural, undisturbed swamp forests. Given the lack of proximity
to the existing drainage network and preliminary DRAINMOD results, it is anticipated that these areas will
meet the criteria for wetland hydrology during periods of normal rainfall.
Areas targeted for preservation maintain remnants of silvicultural species such as loblolly pine, but are also
populated by typical wetland flora such as red bay (Persea palustris), sweet bay (Magnolia virginiana),
loblolly bay (Gordonia lasianthus), and fetterbush (Lyonia lucida). Due to the existence of an intact, mature
canopy, no project activities are proposed for these areas. All of the wetlands within the targeted area will
be preserved through appropriate legal covenants. These covenants will assure that the wetlands will be
protected in their natural state in perpetuity.
IV. PROPOSED MONITORING PLAN
Upon agency concurrence of the final wetland mitigation plan, mitigation site activities will be initiated. Staff
environmental scientists will be present during project construction to ensure that the work is consistent with
the proposed design. An 'as-built' survey will be prepared to document site conditions immediately post-
construction. The mitigation site will be monitored annually for a period of 5 years (or until such time
deemed successful) whichever is longer, to document site development over time. The site will be
evaluated based upon performance criteria related to vegetative density and wetland hydrology.
The primary success criteria for the mitigation bank will be:
Brice Creek Wetland Mitigation Bank Prospectus 7
Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
(1) Demonstrated density of planted species to meet or exceed 320 trees per acre at the end of 3
years (post planting) and 260 trees per acre at the end of 5 years (post-planting).'
(2) No single volunteer species (most notably, red maple, loblolly pine, and sweet gum) will
comprise more than 50% of the total composition at year 2 or 3. If this occurs, remedial
procedures will be implemented. During years 4 &5, no single volunteer species, comprising
over 50% of the total composition, may be more than half the height of the planted trees. If
this occurs, remedial procedures will be implemented.
(3) The hydrologic criterion for the wet hardwood community will be the establishment of a static
water table at, or within, 12" of the soil surface for 8% of the growing season2 (equivalent to 22
days based upon SCS-established growing season March 181h through November 14th) during
periods of normal rainfall.
A. VEGETATION MONITORING
The vegetation monitoring protocol is based upon accepted methods used for other mitigation bank sites of
North Carolina. Specifically, 1% of the planted wetland areas will be monitored via the establishment of
permanent 0.10-acre plots. This areas includes areas currently managed for silvicultural resources,
construction corridors, and removal of existing road beds. Areas of non-target species removal will also be
monitored for a total of 475 planted acres. Given the proposed acreage, a total of forty-seven (47) plots will
be established. GPS coordinates for the centers of each sampling plot will be recorded and included with
the `as-built' survey and subsequent annual monitoring reports. During monitoring, surviving planted
individuals and volunteer individuals will be enumerated within each plot.
B. HYDROLOGY MONITORING
Shallow groundwater hydrology will be monitored via twenty-four (24) automated wells (RDS, Inc. WM-20s)
located within the restoration and enhancement areas. Wells will be installed in accordance with installation
methods outlined in the Wetlands Regulatory Assistance Program (WRAP) Technical Note 00-02 (Sprecher
2000). Water levels will be recorded once daily. Data will be downloaded from the wells every three
1 Volunteer species may be counted toward meeting the success criteria upon evaluation of site-specific conditions and
concurrence by IRT members.
2 As defined by the Soil Conservation Service, the growing season for Craven County is 240 days.
Brice Creek Wetland Mitigation Bank Prospectus 8
Lower Neuse River Basin (HUC 03020204)/White Oak River Basin (HUC 03020106)
months (i.e. once quarterly). Data from well downloads will be compiled and graphically displayed to
demonstrate hydroperiods of monitored areas. As stated earlier,
the hydrologic criterion for the wet hardwood community will be the establishment of a static water
table at, or within, 12" of the soil surface for 8% of the growing season3 (equivalent to 22 days
based upon SCS-established growing season March 181h through November 14th) during periods
of normal rainfall.
V. BANK OPERATION
A comprehensive restoration plan and Mitigation Banking Instrument (MBI) will be developed and submitted
prior to project construction. Upon acceptance of the final mitigation plan by the Interagency Review Team
(IRT), the bank sponsor (Weyerhaeuser) will initiate proposed grading and planting activities for the
development of the Bank site. Mitigation bank credits will be calculated using the following standard:
Mitigation Type Ratio
(1) Wetland Restoration 1:1
(2) Wetland Enhancement 2:1
(3) Wetland Preservation 5:1
Use of credits from the Bank to offset wetland and stream impacts authorized by federal permits or state
water quality certifications must be in compliance with the Clean Water Act, Section 404 (b)(1) guidelines
and other applicable federal and state legislation, regulations, and policies. Prior to release of bank credits,
the following requirements will be met: (1) approval of the final mitigation plan and execution of the MBI; (2)
recordation of the conservation easement; and (3) establishment of appropriate financial assurances. Given
the identified ratios for wetland restoration, enhancement, and preservation it is estimated that 497
nonriverine wetland credits will be derived from the establishment of the Brice Creek Wetland Mitigation
Bank.
The tentative schedule for establishment of the bank site is outlined in Table 2. The credit release schedule
associated with the schedule is outlined in Table 3.
3 As defined by the Soil Conservation Service, the growing season for Craven County is 240 days.

11 Submittal of Monitoring Report #4 to MBRT December 31, 2012
12 Submittal of Monitoring Report #5 to MBRT December 31, 2013
As part of the approval process for the MBI, the Bank Sponsor must obtain the proper financial assurances,
in the form of 2 separate bonds or letters of credit. One bond will cover 30% of the estimated construction
costs and is referred to as the performance bond. The remaining bond will cover 10% of the estimated
monitoring costs for all five years. These assurances will only be invoked in the event the Bank Sponsor is
unable to meet the terms of the MBI (i.e. abandonment of project, etc.). Following successful completion of
construction and monitoring events these bonds may also be renegotiated to reflect the decrease in
financial liability to the sponsor.
Ownership of the site will reside with the Bank Sponsor who intends to transfer a perpetual conservation
easement to an appropriate 501(c)3 non-profit organization (as approved by the IRT) for long-term
protection of the site. Potential easement holders may include NC Coastal Land Trust, NC Wildlife
Resources Commission, or the NC State Agriculture Foundation. The conservation easement will be
recorded upon approval of the mitigation plan and execution of the MBI. The transferee will be responsible
for maintaining the Bank in accordance with a Conservation Easement placed on the Bank Site for perpetual
protection as described in the Mitigation Plan.

In most cases, use of mitigation banks for the purpose of offsetting Section 404/401 authorized impacts
to wetlands would result in the debiting of two credits for each acre of impact proposed. One of the two
credits debited would be required to be a restoration credit.
The sponsor shall develop accounting procedures for maintaining accurate records of debits made from
the bank that is acceptable to the IRT. Such procedures shall include the generation of a debit report by
the sponsor documenting all credits used at the time they are debited from the bank. Debit reports shall
be provided to each member of the IRT within 30 days of the date of credit sale. In addition, the sponsor
shall prepare an Annual Report to be provided to each IRT member within thirty (30) days of each
anniversary of the date of execution of the MBI, showing all credits used and the balance of credits
remaining. The sponsor's reporting obligations hereunder shall end upon the sale of all credits or
termination of the MBI, whichever event first occurs.

VI. CONCLUSION
Initial data collected and reviewed for the Brice Creek tract support the development of a wetland
mitigation bank. Based on these investigations a total of 554 acres are available for restoration,
enhancement, and preservation of wetlands (comprised of nonriverine wet hardwood flats). Restoration
efforts throughout the 554-ac area will provide tangible benefits to water quality and habitat in a rapidly
urbanizing watershed. Additional benefits will also be realized through increases in flood water retention
and groundwater recharge rates.
By providing wetland restoration credits prior to authorized impacts, overall disturbance and loss of
function within the watershed are minimized. Furthermore, the proposed hardwood forest plantings will
provide improved foraging habitat within a predominantly monoculture section of the Croatan National
Forest, generating ancillary benefits to large fauna. Overall, the project has the potential to generate
positive ecological benefits within a watershed currently experiencing acute development pressure.
