I. EXECUTIVE SUMMARY
On behalf of the Bank Sponsor, Coastal Carolina Developers (CCD), Land Management Group,
Inc. (LMG) is submitting the following prospectus to develop the Greenview Ranches Umbrella
Mitigation Bank. The proposed bank is designed to provide compensatory mitigation for authorized
non - riparian wetland impacts within a portion of the Northeast Cape Fear River Basin (USGS 14-
digit hydrologic units 03030007140010 and 03030007120010) and the Atlantic Intracoastal
Waterway (ICWW) portion of the White Oak River Basin (USGS 14 -digit hydrologic units
03030001040005, 03030001040010, and 03030001040020). The ICWW watershed is grouped
within the White Oak River Basin by USGS hydrologic units but is considered to be part of the
Cape Fear River Basin by the NC Division of Water Quality (DWQ Subbasin 03- 06 -24). The initial
phase of the bank will consist of one 102 -acre tract located in New Hanover County, North
Carolina. The tract consists of non - riparian pocosin wetlands degraded by historical drainage
improvements to the initial 1962 Greenview Ranches subdivision which divided 2,200 -acres into 5-
acre lots. Additional ditching and road work were done in the 1980's. Additional lots in the
Greenview Ranches subdivision are currently being evaluated for potential inclusion in the
proposed Bank. There are several 5 -acre parcels of pocosin wetland in the Greenview Ranches
area that would be ideal candidates to add to the umbrella bank for restoration and /or preservation.
Should the Sponsor determine that these are viable wetland and /or stream mitigation sites, the
Interagency Review Team (IRT) will be notified of the Sponsor's intent to prepare an umbrella
mitigation banking instrument (MBI). The following Prospectus provides more specific information
on the Greenview Ranches Tract. The information provided is intended to serve as the basis for
the establishment of the MBI.
The Greenview Ranches Tract, located just north of Wilmington, provides a rare opportunity to
restore part of a vast headwater wetland area in an urban area. The wetlands of Greenview
Ranches have been impacted since at least the early 1960s. At the present time a ditch network
exists throughout the property, which has lowered wetland water tables and has contributed to
degraded water quality within this section of densely populated New Hanover County. The
Greenview Ranches Umbrella Mitigation Bank Prospectus 1
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
proposed project, totaling 102 acres, will provide for approximately 37 acres of restoration, 33
acres of enhancement, and 14 acres of preservation for these non - riparian wetlands. Mitigation
work will principally involve the backfilling and /or plugging of the existing drainage network and the
removal of existing roads. The project will result in the re- establishment of natural wetland
hydroperiods and restore /enhance lost and degraded wetland functions.
The following prospectus provides general information regarding the existing conditions as well as
preliminary acreage totals for the proposed restoration, enhancement, and preservation of
wetlands on the Greenview Ranches tract. Additional field investigations will be conducted to
develop a more comprehensive mitigation plan that will be submitted following the review of this
prospectus by the IRT. The mitigation plan will also incorporate any comments from the
interagency review team. Following the successful establishment of the Greenview Ranches
Umbrella Mitigation Bank, the Sponsor may pursue the addition of other parcels in this cataloging
unit to expand this bank into adjacent sections of the impacted Greenview Ranches subdivision
that stretch to the east to US Highway 17.
I. INTRODUCTION
A. Project Overview
The proposed Greenview Ranches site (approximately 102 acres) consists predominantly of
pocosin wetlands that drain to Smith Creek. These non - riparian wetlands have been historically
ditched and maintained since at least the early 1960s. The network of drainage ditches serve to
lower groundwater tables and intercept surface water — thus compromising the ecological functions
(i.e. nutrient/sediment retention, pollution removal, etc.) characteristic of pocosin wetlands. The
existing drainage network diverts subsurface flow into a perimeter ditch on the southern property
line which drains into Smith Creek. Based upon preliminary site investigations, approximately 84
acres of non - riparian wetlands can be restored, enhanced, and preserved on the site.
The site consists predominantly of drained hydric soils characteristic of pocosins and broad
interstream flats of the outer Coastal Plain. The Murville fine sand soil mapping unit comprises the
vast majority of the site. This series is a very poorly drained soil characteristic of non - riparian
Greenview Ranches Umbrella Mitigation Bank Prospectus 2
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
wetlands occurring on flats and slight depressions. A small portion of the site is mapped as
Seagate fine sand. This series is somewhat poorly drained and occurs in nearly level flatwoods.
LMG has also conducted a preliminary mapping of the hydric soil boundaries of the site. The
findings of this effort indicate that the entire site consists of hydric soils. Approximately 13,000
linear feet of open ditching currently exists throughout the site. Historic site ditching has lowered
water table levels throughout a majority of the site and effectively removed and /or compromised
wetland hydrology. Generally, areas located further away from the ditches still retain wetland
hydrology. A comprehensive wetland delineation performed by LMG and subsequent survey
indicates that 50.22 acres of jurisdictional wetlands remain on the tract. LMG has received
concurrence on the delineation findings by the USACE, and a final jurisdictional determination has
been received (SAW- 2011 - 01979, expires 1/13/2017).
The remaining 84 acres +/- is considered suitable for non - riparian wetland restoration,
enhancement, and preservation. Given the landscape position and soil types occurring on the
tract, nearly the entire 102 -acre project area formerly consisted of non - riparian pocosin habitat
(NCWAM 2010). Based upon the proposed mitigation, the bank site will result in 56.3 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 immediately southwest of the intersection of Murrayville Road and Plantation
Road (east of Interstate 40 and south of US17 bypass), near Wilmington (New Hanover County),
NC. The former residential development site is located near the headwaters of Smith Creek.
Refer to the enclosed site location map (Figure 1), USGS topographic quadrangle (Figure 2),
LIDAR topographic map (Figure 3), and the Pender County Soil Survey map (Figure 4) for
additional site information. A 2010 aerial photograph of the site (Figure 5) is also enclosed for
reference.
C. Watershed Characterization
Although 60% of the Greenview Ranches subdivision is located within the Northeast Cape Fear
River watershed (DWQ Subbasin 03- 06 -23), it is believed that this mitigation bank would provide
Greenview Ranches Umbrella Mitigation Bank Prospectus 3
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
appropriate compensatory mitigation to offset wetland impacts within the ICWW watershed (DWQ
Subbasin 03- 06 -24). Although a private mitigation bank serving the Northeast Cape Fear River
watershed is currently being developed, no private mitigation bank currently exists within this urban
watershed. The ICWW subbasin consists of forests /wetlands, low- density residential areas, urban
areas, agriculture, and pasture /managed pine plantations south of US Hwy 17 along the coast.
Increased development and population growth is expanding in these coastal areas between
Wilmington and Jacksonville, NC. According to the Cape Fear Basinwide Water Quality Plan
(NCDWQ 2005), population growth is expected to grow by 110,000 people in the counties with
portions or all their areas within this subbasin by 2020. Streams and waterbodies within the
watershed are susceptible to impairment from fecal bacteria contamination and low ambient
dissolved oxygen (DO) concentrations. Many segments of the ICWW are impaired for shellfish
harvesting and will be added to the 303(4) list of Impaired Waters (NCDWQ 2005).
Wetlands within the project area drain indirectly to Smith Creek through a network of drainage
ditches. Smith Creek is part of the Northeast Cape Fear River watershed (DWQ Subbasin 03 -06-
23). The entire reach of Smith Creek from its source to its confluence with the Northeast Cape
Fear River (11.1 miles) is impaired for aquatic life and will be added to the 303(4) list of Impaired
Waters (NCDWQ 2005). The NCDWQ surface water body classification for Smith Creek is C -Sw
and applies to the entire stream, which is located immediately down - gradient of the project site
(NCDWQ 2005). "C" denotes waters that are protected for secondary recreation, fishing, wildlife,
fish and aquatic wildlife propagation and survival, agriculture, and other uses. "Sw" denotes
swamp waters with very low velocities.
The proposed addition of the Hampstead Bypass to the existing interstate highway system will
likely result in secondary impacts and contribute to increased development pressures currently
affecting this watershed (refer to A). Overall, the Northeast Cape Fear River and its tributaries
(including Smith Creek) are susceptible to water quality impairments associated with low DO, high
total nitrogen, and high total phosphorous. High nutrient concentrations originate from non -point
source loading. Sediment loading (associated with intensive silvicultural and agricultural drainage
practices) is prevalent throughout the watershed. These impairments tend to be exacerbated by
channelization of streams and ditching of adjacent headwater wetlands, resulting in diminished
Greenview Ranches Umbrella Mitigation Bank Prospectus 4
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
nutrient uptake and nutrient/sediment loading to down - gradient waters.
D. Mitigation Goals
The goal of the proposed umbrella bank is to provide high - quality compensatory mitigation for
permitted impacts to non - riparian wetlands within the ICWW watershed and a portion of the
Northeast Cape Fear River Basin via the restoration, enhancement, and preservation of wetlands.
The proposed activities at the Greenview Ranches site will restore the hydrology of characteristic
non - riparian pocosin wetland communities within the first phase of the bank. Refer to Table 1 for
the type and quantity of mitigation proposed at this time. Since the Greenview Ranches
Subdivision stretches over to US Highway 17 to the east, it is the desire of the bank sponsor to
provide an avenue for other parcel owners within the Greenview Ranches subdivision to sell their
land locked parcels for conservation purposes.

The following categories of ecological functions have been targeted for restoration or enhancement
via the proposed mitigation work on the Greenview Ranches tract.
BIOGEOCHEMICAL CYCLING — The restored pocosin wetland system will capture precipitation in
the upper reaches of the watershed and provide for increased storage. The increased retention
times will allow for a suite of biotic and abiotic processes to convert nitrogen and other nutrients
into different forms that may be readily consumed by the surrounding plant community. This
retention also allows for sediment to settle out of solution, reducing pollution in Smith Creek down-
gradient of these pocosin wetlands in their relatively high landscape position.
HYDROLOGIC — Restoration of the pocosin wetland complex will result in the expansion of the
subsurface water storage component of the ecosystem. The increase in storage volume and time
will reduce peak discharge and provide a valuable substrate for replenishment of groundwater.
The increase in storage will also benefit the adjacent Smith Creek stream system by increasing
valuable base flow during drought conditions.
PLANT AND ANIMAL HABITAT — The existing vegetative assemblage of native pocosin species
provides food and habitat for wildlife. Once characteristic wetland hydrology is restored, these
plants will benefit from increased source water and a corresponding increase in transpiration. The
site includes a variety of low - pocosin and high - pocosin subtypes. When coupled with the variation
in topography, these areas provide valuable heterogeneity which supports a more diverse food

White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
web within the ecosystem. This diversity provides a variety of food sources and refuge habitat for
resident and transitory species. Restoration of the endemic community types will also provide for
connectivity between the Greenview Ranches site and the expansive pocosin wetland complex
which borders the site.
E. Proposed Geographic Service Area
The Greenview Ranches 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 B). 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 Cape Fear 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 reasonably be
expected to provide appropriate compensation for impacts to similar wetland and /or other stream
or aquatic functions. The site is located within the Northeast Cape Fear Hydrologic Unit
(Hydrologic Unit Code 03030007). The proposed GSA includes two 14 -digit HUCs of the
Northeast Cape Fear River and three 14 -digit HUCs of the White Oak River Basin (ICWW
watershed). Note that the ICWW watershed is grouped within the same sub -basin as the
Northeast Cape Fear River based upon NCDWQ basinwide maps. Refer to Figure 6 for the
location and extent of the proposed GSA. The mitigation banking instrument will identify the
specific approved GSA upon further consultation with the IRT.
The proposed project will serve as the initial source of credits in a general use mitigation bank
serving the identified GSA. The purpose of the Greenview Ranches mitigation project is to provide
for high - quality mitigation to offset wetland losses authorized by applicable federal and state
Greenview Ranches Umbrella Mitigation Bank Prospectus 7
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
regulatory programs. Following the successful establishment of the Greenview Ranches Mitigation
Bank, future sites may be added under an umbrella instrument. There are several 5 -acre parcels
of pocosin wetlands in the Greenview Ranches area extending to the US Highway 17 Bypass that
would be ideal urban parcel candidates to add to the umbrella bank for restoration and /or
preservation.
BASELINE CONDITIONS
A. Community Types
The tract consists of a mixture of former and existing pocosin communities. The pocosin
community is comprised of broad interstream flats underlain by mineral soils. Remnant areas of
this wetland community type are still present (refer to the attached wetland delineation map —
Appendix C). The wetland type targeted for restoration is non - riparian pocosin. Based upon the
Cowardin classification for wetland and deepwater habitats (Cowardin et al. 1979), the wetland
community type to be restored is Palustrine Forested Wetland (needle - leaved evergreen).
B. Vegetation
Dominant wetland vegetation of the tract includes species such as pond pine (Pinus serotina), red
bay (Persea palustris), sweet bay (Magnolia virginiana), loblolly bay (Gordonia lasianthus), catbrier
(Smilax species), fetterbush (Lyonia lucida), bitter gallberry (Ilex glabra) and titi (Cyrilla
racemiflora). Cinnamon fern (Osmunda cinnamomea) and smaller versions of the shrub species
are common herbaceous species of these areas. A large portion of the former wetland habitat on
the tract has been drained by an extensive ditch network. As indicated earlier, the drainage
network and adjacent dirt access roads appear to have been installed sometime during the early
1960s with additional work in the 1980s (refer to attached historic aerial photographs in Appendix
D). At the time of LMG's preliminary site investigations (Spring 2010 and Summer through Winter
2011/2012), the majority of the drained areas proposed for restoration had been selectively thinned
and bush - hogged.
Drained wetland areas (suitable for restoration) exhibit a mix of species indicative of changes in
hydrology. Remnant wetland canopy species (e.g. pond pine) tend to persist in most areas.
However, subcanopy species and herbaceous vegetation is indicative of drier conditions resulting
from site drainage. These species include yellow jasmine (Gelsemium sempervirens), horse sugar
Greenview Ranches Umbrella Mitigation Bank Prospectus 8
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
(Symplocos tinctoria), bracken fern (Pteridium aquilinum), and Carolina laurel (Kalmia carolina).
Pond pine remains as the dominant canopy species throughout the site.
C. Soil Characteristics
The tract (located at the upper end of the Smith Creek watershed) exhibits nearly level to gently
sloping topography. The site and surrounding area is grouped in the Murville- Seagate -Leon
general soil unit. This assemblage is characterized by very poorly drained to somewhat poorly
drained soils that have sandy surfaces on uplands and stream terraces. The predominant wetland
soil unit occurring on the tract is the Murville fine sand soil series. These soils occur on flats or in
slight depressions on uplands and are very poorly drained (refer to Figure 4). This soil series is
characterized by low chroma (black) sandy surfaces with a loamy feel and appearance that results
from organic matter content. The black fine sandy surface typically extends to 45 ", at which point it
is underlain by pale brown fine sand. A small portion of the site (along the southern property
boundary) is mapped as Seagate fine sand. This series is somewhat poorly drained and occurs in
nearly level flatwoods.
D. Hydrology /Hydraulic Characteristics
The tract is located within the upper end headwaters of the Smith Creek watershed. A drainage
network (of varying ditch size and spacing) effectively drains most of the former non - riparian
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. Oxidation of surficial organics is another indication of long -term drainage.
Given the predominant soil type on the tract and observed field indicators, the lateral drainage
effect of the ditches was estimated to be approximately 300 ft to 400 ft depending upon the depth
of the ditch and the topography of the adjacent land. 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.
III. CONCEPTUAL PLAN
A. Hydrology Restoration
The proposed mitigation bank includes the restoration of up to 84 acres of non - riparian wetland
habitat via the backfilling and /or plugging of ditches. In addition, removal of the roadbeds will allow
Greenview Ranches Umbrella Mitigation Bank Prospectus 9
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
for surface water to sheetflow along its natural gradient following major storm events. Installation
of ditch plugs and associated grading work along ditches will restore characteristic wetland
hydrology to pocosin areas. Future topographic survey work and additional drainage evaluations
will help to determine the specific limits of the proposed earthwork. Refer to Figure 7 for a
conceptual plan map depicting proposed areas of restoration.
B. Vegetation Restoration
Excluding the soil roads, the tract contains existing vegetation that is characteristic of the pocosin
wetland type. Areas to be graded for hydrologic restoration (ie. former roadbeds) will be planted
with characteristic wetland species. Plantings associated with the broad, interstream divide
landscape position and soil type will include pond pine, loblolly bay, red bay, Atlantic white cedar
(Chamaecyparis thyoides), and black gum (Nyssa sylvatica). Tree seedlings will be planted on 9 -ft
spacings (equivalent to a density of 538 stems /acre). It anticipated that characteristic shrub
species (e.g. gallberry, inkberry, fetterbush, American titi) will volunteer into the restored wetland
areas.
C. 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 in the Smith Creek local watershed. Vegetative restoration in
existing roads will provide for increased foraging and refuge habitat for resident and migratory
species. Removal of existing roadbeds will also facilitate interconnectivity for wildlife by eliminating
artificial edges. Preservation of the site will provide habitat connectivity to the vast network of
pocosin wetlands in the Greenview Ranches area and provide a corridor to Smith Creek. In light of
acute development pressures in this region of eastern North Carolina, the Northeast Cape Fear
River Basin is particularly susceptible to loss of wetland functions and associated watershed
impacts. The construction of the proposed Hampstead Bypass will only exacerbate these
development pressures within the area immediately surrounding the site. By providing for
successful restoration of this pocosin non - riparian wetland complex, the mitigation bank will help to
replace wetland functions critical to water quality and wildlife habitat in the area.
D. Earthwork /Site Preparation (Wetland Restoration)
Earthwork will include the backfilling of ditches and the installation of clay plugs to promote
Greenview Ranches Umbrella Mitigation Bank Prospectus 10
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
hydrologic restoration of the site. Clay plugs will be 50 -ft in length. The plugs (sited primarily near
ditch outlets) will be reinforced with filter- fabric and rip -rap to ensure long -term stability and
functioning. Existing soil roads will be removed. These areas will be planted with characteristic
bay forest (i.e. pocosin) tree species. Source material from the roadbeds will be used to backfill
the adjacent ditches. Material will be consolidated to effectively impede drainage. As a result,
portions of the roadside ditches will remain as open water habitat pending final cut/fill volumes.
Topographic survey and additional soil profile evaluations will determine the location and extent of
earthwork to be conducted.
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 one 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.
E. Wetland Enhancement
Wetland enhancement is targeted for approximately 33 acres of the project site (Figure 7).
Enhancement will be achieved via re- establishment of characteristic wetland hydrology. While the
enhancement areas are believed to meet the minimum criterion for wetland hydrology, their
proximity to existing ditches has resulted in compromised hydroperiods (i.e. reduced duration and
amplitude). Some of the enhancement areas, particularly in the southeastern part of the site, are
relatively far away from any ditches on site than can be manipulated. However, numerous field
investigations and preliminary well data indicate that these wetlands exhibit impaired hydrology.
Additional well data and DRAINMOD simulations will help to refine the extent of wetland areas
targeted for enhancement.
F. Wetland Preservation
Approximately 14 acres of existing, relatively undisturbed non - riparian pocosin wetlands have been
identified for preservation within the site (Figure 7). Wetland hydrology in these areas appears to
be relatively unaltered by drainage features of the site. This has been confirmed via several site
evaluations and the subsequent jurisdictional determination.
Greenview Ranches Umbrella Mitigation Bank Prospectus 11
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
Areas targeted for preservation are populated by typical pocosin wetland flora such as pond pine,
red bay, sweet bay, loblolly bay, and fetterbush. Due to the existence of characteristic pocosin
vegetation and relatively unaltered hydrology, no earthwork or planting activities are proposed for
these areas. All of the existing wetlands within these areas 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
A. Proposed Success Criteria
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 up to seven (7) years (or until such time deemed successful) whichever is longer, to
document site development over time. Note that during the development of the banking
instrument, the Sponsor will coordinate with the IRT for the final, accepted terms and duration of
post- construction performance monitoring. The site will be evaluated based upon performance
criteria related to wetland hydrology throughout restoration and enhancement areas and vegetative
density in areas to be replanted (ie. former road bed areas).
The proposed primary success criteria for the mitigation bank are:
(1) Demonstrated density of planted species to meet or exceed 320 trees per acre at the
end of 3 years (post planting) and 210 trees per acre at the end of 7 years (post-
planting). 1
(2) No single volunteer species (most notably, red maple 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 and 5, no single volunteer species,
1 Volunteer species may be counted toward meeting the success criteria upon evaluation of site - specific conditions and
concurrence by IRT members; however, these species will be tracked separately.
Greenview Ranches Umbrella Mitigation Bank Prospectus 12
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
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 will be the establishment of a static water table at, or within,
12" of the soil surface for 10% of the growing season.
B. 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 area includes the removal of existing road beds.
Given the proposed acreage (approximately 1.3 acres), a total of one (1) plot will be established.
GPS coordinates for the center of the 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.
C. Hydrology Monitoring
Shallow groundwater hydrology will be monitored via twelve (12) automated wells (RDS, Inc. WM-
40s) located within the restoration, enhancement, and preservation 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 months (i.e. once quarterly). Data from well
downloads will be compiled and graphically displayed to demonstrate hydroperiods of monitored
areas. The hydrologic success criterion for the enhancement areas will be similar to those criteria
identified above and will demonstrate an increase in the duration of hydroperiods relative to
baseline pre- construction conditions.
Please note that the final, approved performance criteria will be identified in the banking instrument
and the comprehensive mitigation plan based upon further consultation with the IRT.
V. BANK OPERATION
The Bank Sponsor, Coastal Carolina Developers (CCD), owns fee simple title for the land included
Greenview Ranches Umbrella Mitigation Bank Prospectus 13
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
within the proposed mitigation bank. The Sponsor has control of all ditches and waters within the
site. Since the restoration is premised on re- establishment of groundwater hydrology via removal
of ditches, all water rights necessary for sustainability of the bank are secured through the fee
simple ownership. The Sponsor has contracted with LMG for environmental services associated
with the design and implementation of the bank site. Over the last decade, LMG has designed and
implemented numerous wetland restoration projects for full - delivery (EEP and NC DOT), private
wetland and stream mitigation bank sites, and project - specific permit mitigation.
Many of the site evaluations (e.g. wetland boundary survey, final jurisdictional determination, and
preliminary hydrologic monitoring) have been completed for the site. More detailed habitat
assessment and survey work will be necessary for the development of the comprehensive
mitigation plan. A jurisdictional wetland boundary survey signed by the USACE will also be
submitted with the final mitigation plan and banking instrument. Upon acceptance of the final
mitigation plan and execution of the MBI by the (IRT), the bank Sponsor (CCD) 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 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 56.3 non - riparian wetland credits will be derived from the
completion of mitigation and monitoring activities on the Greenview Ranches site. Additional sites
Greenview Ranches Umbrella Mitigation Bank Prospectus 14
White Oak River Basin (HUC 03030001) and Northeast Cape Fear River Basin (HUC 03030007)
may be added in the future under the Smith Creek Umbrella Mitigation Bank.
The tentative schedule for establishment of the bank site is outlined in Table 2. The corresponding
credit release schedule is outlined in Table 3. Note that the final, approved credit release schedule
will be identified in the banking instrument prior to execution by IRT members and the Sponsor.

As part of the approval process for the MBI, the Bank Sponsor must obtain the proper financial
assurances, in the form of two 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 the North Carolina
Coastal Land Trust, Land Trust for America, Inc., or the North Carolina 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
Site evaluations completed to date indicate that the Greenview Ranches site is well- suited for
non - riparian wetland restoration. It is believed that 84 acres are available for restoration,
enhancement, and preservation of wetlands. Completion of restoration work and protection of
the site will provide tangible benefits to water quality and habitat in a rapidly urbanizing
watershed. Additional habitat benefits (via connectivity to a vast pocosin wetland complex) will
be realized via the long -term protection of the site and eventually umbrella parcels. By providing
wetland restoration credits prior to authorized impacts, overall disturbance and loss of function
within the watershed are minimized. Conservation of the restored site will secure foraging and
refuge habitat in areas currently planned for extensive road construction and disturbance.
Overall, the project has the potential to result in discernable ecological benefits within a
watershed currently experiencing acute development pressure.

Notes
Assessment area appears to be far enough away from ditches to have normal hydrology. Area is near the upstream end of its watershed-, the
area upstream draining to the watershed is relatively undisturbed. This assessment area is contiguous with a much larger wetland type and
wetland complex. Pocosin appears to be —90% of its natural size. Canopy is sparse ( <50% trees) but appropriate for wetland type. Soils are
mucky modified mineral.

Notes
Assessment area appears to have reduced hydrology. Area is near the upstream end of its watershed-, the area upstream draining to the
watershed is relatively undisturbed. This assessment area is contiguous with a much larger wetland type and wetland complex. Pocosin
appears to be —90% of its natural size. Canopy is sparse ( <50% trees) but appropriate for wetland type. Soils are mucky modified mineral.
Ground surface is altered by bedding, ruts, compaction, and a fire plow lane.

❑C Overland flow is severely altered in the assessment area.
❑D Both overbank and overland flow are severely altered in the assessment area.
Notes
Assessment area appears to be far enough away from ditches to have normal hydrology. Area is near the upstream end of its watershed-, the
area upstream draining to the watershed is relatively undisturbed. This assessment area is contiguous with a much larger wetland type and
wetland complex. Pocosin appears to be —90% of its natural size. Canopy is sparse ( <50% trees) but appropriate for wetland type. Soils are
mucky modified mineral.
