South Fork Nutrient Offset and Buffer Mitigation Bank Parcel
Jordan Lake Watershed in the Cape Fear River Basin
The South Fork Nutrient Offset and Buffer Mitigation Bank Parcel ("Parcel") is proposed under the terms
and conditions of the Cane Creek Nutrient Offset and Buffer Umbrella Mitigation Banking Instrument
(UMBI), made and entered into by Wildlands Holdings IV, LLC, acting as Bank Sponsor (Sponsor), and the
North Carolina Department of Environmental Quality (NCDEQ), Division of Water Resources (DWR). The
Parcel shall be planned and designed according to the UMBI, 15A NCAC 02B .0240, and the Consolidated
Buffer Mitigation Rule 15A NCAC 0213.0295 which became effective on November 1, 2015. The BPDP has
also been designed in concurrence with the Cane Creek Stream and Wetland Umbrella Mitigation Bank
(SAW# 2016-00219). The Mitigation Plan for the South Fork Stream and Wetland Mitigation Site has
been submitted to the Interagency Review Team.
The project encompasses land along unnamed tributaries to South Fork Cane Creek in Chatham County,
NC. The primary purpose of the Bank is to provide riparian buffer mitigation credits to compensate for
unavoidable buffer impacts in the 03030002 Hydrologic Unit Code (HUC) of the Cape Fear River Basin,
within the Haw River Sub -watershed of the Jordan Lake Watershed. The Bank may also provide nutrient
offset credits for stormwater requirements with new and existing development requiring nutrient
offsets within the Haw River Sub -watershed of the Jordan Lake Watershed. The bank service area is
depicted in Figure 1.
1.0 Project Location and Description
1.1 Introduction
This Parcel is being proposed to provide stream and wetland mitigation through the creation of a Stream
and Wetland Mitigation Bank Site on unnamed tributaries to South Fork Cane Creek as well as nutrient
offset and buffer mitigation through the creation of a Buffer & Nutrient Offset Bank. Riparian
restoration activities deemed suitable for riparian buffer mitigation will generate 444,747.60 ft' riparian
buffer mitigation credits. Riparian restoration activities deemed suitable for nutrient offsets on this
Parcel could generate 2,249.36 lbs. -Nitrogen per acre and 143.81 lbs. -Phosphorus per acre (with a
delivery factor of 71% and 67% respectively) if converted from riparian buffer mitigation credits.
For purposes of the South Fork Buffer and Nutrient Offset Bank, the Parcel involves restoring riparian
buffers and other riparian areas adjacent to mitigated streams onsite in order to help reduce non -point
source contaminant discharges to downstream waters in the Jordan Lake Watershed within the Cape
Fear River Basin. Approximately 18.13 acres will be protected with a permanent conservation easement.
Out of the 18.13 acres, 15.30 acres will be mitigated to generate Jordan Lake riparian buffer credit. Out
of the 15.30 acres, 5.48 acres qualify for either riparian buffer mitigation credit or nutrient offset credit,
but not both. In general, riparian areas that are restored, enhanced or preserved for buffer or nutrient
offset credits, will be a minimum of 30 feet from the top of stream banks and out to a maximum of 100
feet.
The NC Division of Water Resources (DWR) performed an onsite Site Viability for Buffer Mitigation and
Nutrient Offset on August 9, 2017. The correspondence related to the site visit is attached in the
Appendix and dated April 15 and 16, 2017.

Subjectivity calls for the features were determined by DWR in correspondence dated August 15, 2017
using the 1:24,000 scale quadrangle topographic map prepared by USGS and the most recent printed
version of the soil survey map prepared by NRCS. SF4A, UT1 and UT2 were determined to be subject to
the Jordan Lake Buffer Protection Rule 15A NCAC 02B .0267. UT4 is not subject to the Jordan Lake Buffer
Protection Rules.
The results documented in the Site Viability Letter from DWR dated April 16, 2017 indicated that SF4A,
UT1, UT2 and UT4 are viable for riparian restoration and suitable for buffer mitigation. SF4A, UT1, UT2,
and UT4 are also viable for nutrient offset credits in non -forested pasture areas. These areas are
currently being restored for riparian buffer credit, but may be converted to nutrient offset credit
pursuant to 15A NCAC 02B .0295 and the MBI. Written approval must be granted by DWR prior to any
conversion and transfer of credits.
Photos showing historic site conditions and current site conditions (as of August 2017) of the Parcel are
provided in the appendix. Site conditions have not changed since the DWR 2017 viability letter and
August 2017 site photos.
South Fork Mitigation Site
HUC 03030002 — BPDP
2.2 Parcel Soils
The largely forested watersheds with low rolling topography result in relatively low sediment supply.
The bed material in the streams on this site is small to medium gravel and sand that is derived from
highly weathered parent material.
Soil mapping units are based on the U.S. Department of Agriculture (USDA) Natural Resources
Conservation Service (NRCS) Soil Survey for Chatham County. Soil types within the study area were
mapped with the NRCS Web Soil Survey and are described below in Table 2. The South Fork project area
is dominated by Chewacla loams. This soil frequently floods and is poorly drained, resulting in frequent
occurrence of wetlands. The 1937 Soils Survey Map is provided in Figure 4.

2.3 Existing Vegetative Communities
The cattle pastures on the site are dominated by fescue grasses (Festuca spp.) and broomsedge
(Andropogon virginicus). Much of the riparian areas on the site are wooded; however, cattle have
access to all of the streams except the downstream portion of SF4A, as noted in the DWR Site Viability
letter. Vegetation in the wooded areas is primarily hardwood species including white oak (Quercus alba),
red oak (Quercus rubra), willow oak (Quercus phellos), tulip poplar (Liriodendron tulipifera), sweetgum
(Liquidambarstyraciflua), red maple (Acer rubrum), southern red oak (Quercus falcata), and American
elm (Ulmus americana). Vegetation within the riparian areas along the right bank of SF4A, as noted in
South Fork Mitigation Site
klW HUC 03030002 — BPDP
the DWR Site Viability letter, lack a healthy divers understory and therefore require supplemental
plantings to be viable for generating buffer credits.
2.4 Threatened and Endangered Species
Wildlands utilized the US Fish and Wildlife Service (USFWS) and NC Natural Heritage Program (NHP)
databases to search for federally listed threatened and endangered plant and animal species in Chatham
County, NC. Two animal and one plant species identified as threatened or endangered are currently
listed in Chatham County (Table 3).

Endangered
A letter was sent to the USFWS on April 1, 2016, requesting a review of the project and comment on
potential effects on endangered species or other resources. The USFWS responded on July 22, 2016, and
stated the "proposed action is not likely to adversely affect any federally listed endangered or
threatened species, their formally designated critical habitat or species currently proposed for listing
under the Act..." USFWS also stated a concern for potential sediment loss during the stream and
wetland mitigation construction period. These concerns are addressed in Section 3.0 below. All
correspondence with USFWS is included in Appendix 5. A pedestrian survey of the project area was
performed on November 7, 2016. No suitable habitat and/or individually federally listed species were
identified in the project area.
2.5 Cultural Resources
The site is not located near any sites listed on the National Register with the State Historic Preservation
Office (SHPO). A letter was sent to the SHPO on April 1, 2016, requesting a review of the project and
comment on potential effects on archeological and cultural resources. SHPO responded on July 1, 2016
stating that they are not aware of any historic resources that would be affected by the project.
2.6 Environmental Issues
An EDR Radius Map Report with Geocheck was ordered for the Parcel through Environmental Data
Resources, Inc. on April 7, 2016. The target property and the adjacent properties are not listed in any of
the Federal, State, or Tribal environmental databases searched by EDR. There were no known or
potential hazardous waste sites identified within one mile of the Parcel. The Executive Summary of the
EDR report is included in the Appendix.
3.0 Riparian Restoration, Enhancement and Preservation Plan
Developing the Parcel for mitigation will require converting existing agriculture land use practices
adjacent to streams into riparian forest. The mitigated riparian areas, which includes the 50 -foot -wide
Jordan Lake riparian buffers, will involve replanting appropriate native tree species along the project
corridors. Vegetation management and herbicide applications may be needed during the first year of
tree establishment in the restoration areas to prevent establishment of invasive species that could out
South Fork Mitigation Site
HUC 03030002 — BPDP 4
compete the planted native species. More detailed descriptions of the proposed restoration activity
follow in Sections 3.1-3.4 and are shown on Figure 5.
This site is also being proposed as a stream and wetland mitigation bank; therefore, restoration of
riparian areas will be accomplished through the goals and methods outlined by the Cane Creek Umbrella
Mitigation Banking Instrument — South Fork Stream Mitigation Plan (USACE # 2016-00219) and the
South Fork Riparian Buffer & Nutrient Offset Mitigation Banking Instrument. All applicable federal,
state, and local documentation, permits, and/or authorizations will be acquired as part of implementing
the above-mentioned mitigation plan and will be provided to DWR as part of the As Built Report
including Section 401, Section 404 and Sediment and Erosion Control permits.
All riparian restoration activities will commence in concurrence with the stream mitigation activities and
not before. Therefore, the mitigation area where riparian restoration is being performed may be altered
slightly depending on the implementation of the South Fork Stream Mitigation Plan for the Cane Creek
Umbrella Mitigation Bank.
3.1 Parcel Preparation
The current land uses adjacent to the streams proposed for buffer restoration are primarily non -
forested crops. Areas slated for buffer restoration will require site preparation that will include select
herbicide treatments or limited mechanical clearing to remove undesirable underbrush or invasive
species. Diffuse flow will be maintained in the buffers.
3.2 Riparian Area Restoration Activities
The revegetation plan for the entire buffer restoration area will include permanent seeding, planting
bare root trees, live stakes, and herbaceous plugs and controlling invasive species growth. The specific
species composition to be planted was selected based on the community type, observation of
occurrence of species in riparian buffers adjacent to the Site, and best professional judgement on
species establishment and anticipated Site conditions in the early years following project
implementation. Species chosen for the planting plan are listed on Sheet 2.0 of the preliminary stream
mitigation design plans located in the Appendix and in Table 4. The plans also contain information on
planting zones on Sheets 2.1.

Trees will be planted at a density sufficient to meet the performance standards outlined in the Rule 15A
NCAC 02B .0295 of 260 trees per acre at the end of five years. No one tree species will be greater than
50% of the established stems. An appropriate seed mix will also be applied to provide temporary
ground cover for soil stabilization and reduction of sediment loss during rain events in areas disturbed
by stream construction, as necessary. This will be followed by an appropriate permanent seed mixture.
3.3 Riparian Area Enhancement Activities
The revegetation plan for the buffer enhancement areas under NCAC 02B .0295(n) will include planting
supplemental bare root trees and controlling invasive species growth. The tree species to be planted
are listed in Table 4.
For buffer enhancement areas under NCAC 02B .0295(o), cattle exclusion, planting isn't anticipated to
be needed except where required in the stream mitigation plan. A seed mix will be applied where cattle
have caused bare soils and removed all vegetation and cattle will be fenced out of the easement area.
The proposed fencing boundary is shown on Figure 5.
3.4 Riparian Area Preservation Activities
There will be no parcel preparation work done in the buffer preservation areas, as allowed under 15A
NCAC 02B .0295(o). The preservation area will be protected in perpetuity under a conservation
easement.
Site preparation and planting on the restoration and enhancement areas is scheduled to begin in
January 2019.
4.0 Monitoring and Maintenance Plan
4.1 Monitoring Protocol
Permanent vegetation monitoring plots will be installed and evaluated within the buffer restoration
and/or nutrient offset areas to measure the survival of the planted trees. There may be additional plots
within the riparian buffer that are measuring the success of the riparian areas as part of the stream and
wetland mitigation bank, but only the plots measuring the success of the riparian buffer credit will be
provided in the monitoring reports. The plots will be randomly placed throughout the planted riparian
areas and will be representative of the entire top of bank back one -hundred feet, more or less.
A total of 5 plots will be established within the buffer restoration credit generation area. The number of
monitoring quadrants required is based on the USACE Wilmington District monitoring guidance
documents. The size of individual quadrants will be 100 square meters for woody tree species.
Vegetation assessments will be conducted following the Carolina Vegetation Survey (CVS) Level 2
Protocol for Recording Vegetation (2008). A reference photo will be taken from the southwestern corner
of each of the 5 plots. Photos will be taken from all photo points each monitoring year and provided in
the annual reports. All planted stems will be marked with flagging tape and recorded.
Planting is scheduled for January 2019. The first annual monitoring activities will commence at the end
of the first growing season, at least five months after planting has been completed and no earlier than
the fall season. Species composition, height, and survival rates will be evaluated on an annual basis by
plot. The total number of volunteer woody stems will also be documented and reported. The measures
of vegetative success for the Parcel will be the survival of at least 4 native hardwood tree species, where
no one species is greater than 50% of the established stems, established at a density of at least 260
South Fork Mitigation Site
HUC 03030002 — BPDP
planted trees per acre at the end of Year 5. Appropriate native volunteer species may be included to
meet the performance standards with DWR approval.
A visual assessment of the cattle exclusion and preservation areas within the conservation easement will
also be performed each year to confirm:
• Fencing is in good condition throughout the site;
• no cattle access within the conservation easement area;
• no encroachment has occurred;
• diffuse flow is being maintained in the conservations easement area; and
• there has not been any cutting, clearing, filling, grading, or similar activities that would
negatively affect the functioning of the buffer.
Any issues identified during the visual assessment of the cattle exclusion and preservation areas will be
photographed and mapped as part of the annual monitoring report with remedial efforts proposed or
documented. The Sponsor shall submit the annual monitoring report to DWR by December 31St of each
year for five consecutive years and will follow the terms and conditions of the MBI.
4.2 Parcel Maintenance
Adaptive measures will be developed, or appropriate remedial actions will be implemented in the event
that the Parcel or a specific component of the Parcel fails to achieve the success criteria outlined in
Section 4.1. Site maintenance will be performed to correct any identified problems on the Parcel that
have a high likelihood of affecting project success. Such items include, but are not limited to, excess tree
mortality caused by fire, flooding, drought, or insects. Any actions implemented will be designed to
achieve the success criteria and will include a work schedule and updated monitoring criteria. Any parcel
maintenance performed will be included in the monitoring report for that year. A rigorous herbicide
schedule will need to be implemented in the first few years of tree establishment in the restoration
areas to prevent establishment of invasive species that may attempt to out -compete the planted native
vegetation. The only herbicides used on the Parcel will be aquatic approved herbicides that will be
applied in accordance with North Carolina Department of Agriculture rules and regulations. The
easement boundary will be checked annually as part of monitoring activities and the conditions as well
as any maintenance performed will be reported in the annual monitoring reports to NC DWR.
If mowing is deemed necessary by the Sponsor during the monitoring period, the Sponsor must receive
approval by the DWR prior to any mowing activities within Zone 1 and Zone 2 of the Jordan Lake buffers
to ensure that no buffer violations have occurred.
4.3 Easement Boundaries and Fencing
Easement boundaries will be identified in the field to ensure clear distinction between the Parcel 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. Contact information for
the long-term steward will be provided on boundary markers throughout the site.
4.4 Ownership and Long -Term Management
The Site will remain in private ownership, protected in its entirety, and managed under the terms
detailed in the conservation easement. Unique Places to Save (UP2Save) will serve as the Grantee and
long-term manager and will be the party responsible for long-term management.
South Fork Mitigation Site
HUC 03030002 — BPDP
UP2Save is a 501c3 non-profit organization that is committed to land conservation through sustainable
planning and management. UP2Save has the ability, both logistically and financially, to monitor and
enforce the provisions of the conservation easement and long-term management plan. The organization
operates in a sustainable manner to facilitate operations well into the future. UP2Save has been
approved to serve as the easement holder and long-term manager on several mitigation banks in North
Carolina.
5.0 Financial Assurance
Following approval of the South Fork BPDP, the Sponsor shall provide a Performance Bond from a surety
that is rated no less than an "A-" as rated by A.M. Best. The Performance Bond amount shall be 100% of
the estimated cost for implementation of the project as described in the BPDP, but not less than
$150,000.00. In lieu of posting the performance bond, the Sponsor may elect to construct the project
prior to the first credit release. In that case no performance bond will be necessary.
After completion of the restoration/construction, a separate Performance/Maintenance Bond will be
secured for 100% of the estimated cost to implement the monitoring and maintenance plan but not less
than $100,000.00. The Performance/Maintenance Bond shall apply at the inception of the monitoring
period for a term of one year, to be extended annually for a minimum of five years. Upon DWR
approval, this may be lowered each year based on the adjusted cost to complete the monitoring.
Performance bonds for monitoring shall be renewed to cover the next years monitoring period, with
confirmation of renewal provided to DWR with each annual monitoring report when applicable. DWR
reserves the right to alter the credit release schedule if monitoring reports are submitted without proof
of bond renewals when applicable.
Financial assurances provided in this section must be separate from the financial assurances provided as
part of the Stream and Wetland Mitigation Bank.
6.0 Mitigation Potential
Approximately 18.13 acres will be protected with a permanent conservation easement. Out of the 18.13
acres, a total of 15.30 acres of riparian areas will be mitigated to generate Jordan Lake riparian buffer
credit or nutrient offset credit. Out of those 15.30 acres, 5.48 acres will be restored, 8.84 acres will be
enhanced by permanently excluding livestock and stabilizing soils, 0.52 acres will be enhanced through
supplemental plantings, and 0.46 acres will be preserved (Figure 5). Of the 5.48 acres that are restored,
all 5.48 acres were deemed to be agriculture by DWR and are therefore suitable for either buffer credit
or nutrient offset credit by DWR. These areas may be used for either Jordan Lake buffer credits or
nutrient offset credits, but not both. Out of the 5.48 acres that are restored, the Sponsor is requesting
all 5.48 acres to be used to generate credit releases for riparian buffer credits. Neither riparian buffer
nor nutrient offset credit will be generated on the remaining 2.83 acres (Figure 5). Riparian zones are
depicted in Figure 6.
The Sponsor will maintain up to four (4) credit ledgers. One to account for buffer preservation and
enhancement (via cattle exclusion) credits, one to account for buffer restoration and enhancement
credits (under Rule 15 NCAC 2B .0295(n)) , one to account for Nitrogen nutrient offset credits, and one
to account for Phosphorus nutrient offset credits (if riparian buffer credits are ever converted to
nutrient credits). All buffer ledgers will report credits in both square feet and acres and nutrient offsets
in both pounds and acres. Nutrient offset ledgers must also show both generated credits and delivered
credits. Overall credit generation by drainage feature is detailed in Table 5. The total credit generation
is summarized in Tables 6a and 6b and visually represented in Figure 5. The Sponsor must request and
receive approval from DWR prior to any credit conversions and transfers to the credit ledgers. With each
South Fork Mitigation Site
HUC 03030002 — BPDP
conversion and transfer request submitted to the DWR, the Sponsor will provide all updated credit
ledgers showing all transactions that have occurred up to the date of the request. Buffer preservation
and enhancement credits (via cattle exclusion) from this Bank cannot be converted into Nutrient offset
credits. The credit release schedule is shown in Table 7.
