Grantham Branch Nutrient Offset and Buffer Mitigation Bank Parcel
Neuse River Basin
The Grantham Branch Nutrient Offset and Buffer Mitigation Bank Parcel (“Parcel”) is proposed under
the terms and conditions of the Wildlands Grantham Branch Nutrient Offset and Buffer Mitigation
Banking Instrument (MBI), made and entered into by Wildlands Holdings III, 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 MBI, 15A NCAC 02B .0240,
and the Consolidated Buffer Mitigation Rule 15A NCAC 02B.0295 which became effective on November
1, 2015. The BPDP has also been designed in concurrence with the Grantham Branch Stream and
Wetland Mitigation Site (SAW# 2017‐00549). The mitigation plan for the Grantham Branch Stream and
Wetland Mitigation Site has been submitted to the Interagency Review Team.
The project encompasses land along unnamed tributaries to Falling Creek in Wayne County, NC. The
primary purpose of the Bank is to provide riparian buffer mitigation credits to compensate for
unavoidable buffer impacts in the 03020201 Hydrologic Unit Code (HUC) of the Neuse River Basin,
excluding the Falls Lake Watershed. The Bank may also provide nutrient offset credits for stormwater
requirements with new and existing development requiring nutrient offsets within the 03020201 HUC,
excluding the Falls Lake Watershed. 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 on the southern portion through
the creation of a Stream and Wetland Mitigation Bank Site as well as nutrient offset and buffer
mitigation through the creation of a Buffer & Nutrient Offset Bank. Riparian restoration activities
deemed suitable for nutrient offsets on this Parcel, will generate 2,273.02 lbs‐Nitrogen per acre. The
northern section of the project is nutrient offset and buffer mitigation only (Figure 3).
For purposes of the Grantham Branch Buffer and Nutrient Offset Bank, the Parcel involves restoring
riparian buffers and other riparian areas adjacent to mitigated streams and ditches onsite to help reduce
non‐point source contaminant discharges to downstream waters in the Neuse River Basin.
Approximately 68.78 acres will be protected with a permanent conservation easement. Out of the 68.78
acres, 10.80 acres of riparian areas will be restored for Neuse riparian buffer credit and 4.03 acres
(9,160.27 lbs.‐Nitrogen) of riparian areas will be restored for nutrient credits. Additionally, 0.33 acres
will be preserved for Neuse riparian buffer credit. In general, riparian buffer restoration area widths on
streams will extend out to 100 feet from top of bank for Neuse buffer credits and out to a maximum of
200 feet for nutrient offset credits. Riparian restoration widths on ditches will extend out to 50 feet
from top of bank for Neuse buffer credits and out to a maximum of 200 feet for nutrient offset credits.
The NC Division of Water Resources (DWR) performed an onsite Site Viability for Buffer Mitigation and
Nutrient Offset on February 16, 2017 (letter dated April 18, 2017) for the southern section of the
project. An additional in office assessment was performed by DWR on the northern section of the
project on November 17, 2017. The two site viability letters for buffer mitigation and nutrient offset are
included in the Appendix.

HUC 03020201 – BPDP 2
1.2 Parcel Location
The Parcel is located approximately 10.5 miles northeast of Newton Grove and 8.5 miles northwest of Mt.
Olive. The Site is located within the 14‐digit HUC 03020201170010 and the North Carolina Division of
Water Resources Sub‐basin 03‐04‐12 (Figure 2).
From Raleigh take I‐40 East to NC‐50 S/NC‐55 E in Newton Grove. Take exit 341 from I‐40 and follow NC‐
50 S/NC‐55 E (Raleigh St.) to Newton Grove, then take US‐13 North (Goldsboro St.) for 14 miles to
Grantham School Rd. Turn right (south) on Grantham School Rd. and the destination will be on the right
in one mile. Use 560 Grantham School Rd., Goldsboro, NC 27530 for mapping purposes.
2.0 Project Area ‐ Existing Conditions
2.1 Parcel Features
The project includes restoring riparian areas along two unnamed tributaries to Falling Creek, as shown
on Figure 3 and listed in Table 1. Grantham Branch and UT1 are classified as Nutrient Sensitive Waters
(NSW) by DWR and flow into Falling Creek, which flows into the Neuse River.

***More information was requested by DWR to determine if the depth of the ditch meets 15A BCAC 02B .0295 (o)(8)(D). The
supporting documentation showing compliance with the rule is included in the Appendix.
**** More information was requested by DWR to determine if the landuse adjacent to the left bank of the ditch meets 15A
BCAC 02B .0295 (o)(8)(C). The supporting documentation showing compliance with the rule is included in the Appendix.
Subjectivity calls for the features were determined by DWR in correspondence dated April 7, 2017 and
November 17, 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. Grantham Branch and UT1 were
determined to be subject to the Neuse Buffer Protection Rule 15A NCAC 02B .0233. Ditches (D1 and D2)
are not subject to the Neuse Buffer Protection Rules. Two additional ditches, other than D1 and D2, are
documented in the letter as well, but neither buffer nor nutrient offset credit are being requested on
the ditches.
The results documented in the Site Viability Letters from DWR dated April 18, 2017 and November 17,
2017 and the additional supporting documentation regarding the depth of the ditches, watershed size,
and directional flow of surface flow runoff adjacent D1, indicate that all four Features listed in Table 1
are viable for riparian restoration and suitable for buffer mitigation and are also viable for nutrient
offset credits in non‐forested areas (Appendix).
Grantham Branch Mitigation Bank Parcel
HUC 03020201 – BPDP 3
The Buffer Interpretation /Clarification Memo #2008‐019 applies to Features D1 and D2 where
maintenance of diffuse flow onsite is unattainable. Photos showing historic site conditions and current
site conditions (as of October 2017) of the Parcel are provided in the appendix.
2.2 Parcel Soils
The glauconitic, quartz sand and clay common to the Tar Heel Formation are reflected in the floodplain
soils located on the Parcel. They are deep sandy loam soils (depth to bedrock > 80 inches) that
frequently pond and hold water at the surface. Moving up gradient in the landscape, the soils are
comprised of marine deposits that flood less frequently but maintain a loamy texture. The predominant
floodplain soils on site are described in Table 2 and Figure 4 are based on the U.S. Department of
Agriculture (USDA) Natural Resources Conservation Service (NRCS) Soil Survey for Wayne County (USDA,
1974 and 2015).

2.3 Existing Vegetative Communities
Row Crop Areas
The growth of native vegetation is highly restricted in the riparian areas onsite due to current
agricultural practices. Vegetation within these areas is limited to the targeted agricultural crop, which
has been corn and soybeans in recent years. These are the areas that are being proposed for riparian
restoration to generate buffer and nutrient offset credits.
Forested Areas
While portions of the Falling Creek floodplain west of the Grantham Branch catchment were logged as
recently as 2007, these areas have regenerated with native hardwood vegetation and include multiple
strata (canopy, understory, and herbaceous). Canopy vegetation in all forested areas consists of water
oak (Quercus nigra), willow oak (Quercus phellos), swamp chestnut oak (Quercus michauxii), tulip poplar
(Liriodendron tulipifera), sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), and sweetbay
(Magnolia virginiana). Understory species include black willow (Salix nigra) and tag alder (Alnus
serrulata). Herbaceous layer species include switch cane (Arundinaria tecta), common rush (Juncus
effusus), and hydric sedges.
The watershed has likely been periodically logged since humans settled this area, and many tree species
located in surrounding riparian areas are now mid successional. The species in these areas are not
necessarily indicative of what would have been on‐site before human disturbance.
Grantham Branch Mitigation Bank Parcel
HUC 03020201 – BPDP 4
Invasive Species
One of the characteristics of the site that contributed to its selection as a mitigation bank was the
minimal density and quantity of invasive species on the site. There is an area that contains Chinese
privet on the downstream end of Grantham Reach 2 within the wooded area. These individuals will
require intervention as part of the stream and wetland mitigation bank to reduce on‐site seed sources
and the potential for spread within the entire project site.
2.4 Threatened and Endangered Species
The US Fish and Wildlife Service (USFWS) and the NC Natural Heritage Program (NHP) databases were
searched for federally listed threatened and endangered plant and animal species in Wayne County, NC.
Two animal species are identified as threatened or endangered is currently listed in Wayne County
(Table 3).
Table 3. Listed Threatened and Endangered Species in Wayne County, NC – Grantham Branch BPDP
Species
Federal Status Habitat
Common Name Scientific Name
Red‐Cockaded

Their summer habitats consist of crevices in both
live and dead trees, along with human‐made
structures. This bat is a philopatric species and will
return to their hibernaculum that can consist of
underground caves, cave‐like structures with large
passages containing cracks/crevices, and covered
bridges (railroad tunnels).
Wildlands sent scoping letters to the USFWS on June 1, 2017. The letters included investigation into the
presence of threatened and endangered species on Site protected under The Endangered Species Act of
1973. The biological conclusion for the Site, per the response by USFWS on June 23, 2017, is that the
“proposed action [in this project] 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.” A copy of the letter from USFWS is included in the Appendix.
2.5 Cultural Resources
Review and comment from the State Historic Preservation Office (SHPO) with respect to any
archeological and architectural resources related to the Parcel was requested on June 1, 2017. SHPO
responded on June 3, 2017, and stated they “are aware of no historic resources which would be affected
by the project”. All correspondence is included in the Appendix.
3.0 Riparian Restoration & Preservation Plan
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 Falling Creek
Umbrella Mitigation Banking Instrument ‐ Grantham Branch Stream & Wetland Mitigation Plan (USACE #
2017‐00549) and the Grantham Branch Riparian Buffer & Nutrient Offset Mitigation Banking Instrument.
All applicable federal, state, and local documentation, permits, and/or authorizations will be acquired as
Grantham Branch Mitigation Bank Parcel
HUC 03020201 – BPDP 5
part of implementing the above‐mentioned mitigation plan and will be provided to DWR as part of the
As Built Report (Figure 5) including Section 401, Section 404 and Sediment and Erosion Control permits.
Developing the Parcel for mitigation will require converting existing agriculture land use practices within
riparian areas adjacent to streams and ditches into a dense and diverse vegetated riparian forest. The
riparian areas, which includes the 50‐foot‐wide Neuse 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 control establishment of
invasive species that could out compete the planted native species. More detailed descriptions of the
proposed restoration activity follow in Sections 3.1 and 3.2.
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 Stream & Wetland Mitigation Plan for the Stream &
Wetland Mitigation Bank. The riparian restoration areas will be surveyed, and information provided in
the As‐Built report and corresponding As Built Survey.
3.1 Parcel Preparation
The current land uses adjacent to the streams proposed for riparian restoration are primarily non‐
forested croplands, except for a small preservation area in the northern section of the Parcel. Areas
slated for riparian restoration will require limited site preparation that will include select herbicide
treatments or select mechanical clearing to remove undesirable underbrush or invasive species. Diffuse
flow will be maintained in the buffers, with two exceptions. It is necessary to keep two ditches open to
allow for drainage from a residential area and farm fields. The Buffer Interpretation /Clarification Memo
#2008‐019 applies to Features D1 and D2 where maintenance of diffuse flow onsite is unattainable.
3.2 Riparian Restoration Activities
The revegetation plan for the entire riparian restoration area will include permanent seeding, planting
bare root trees, live stakes, and herbaceous plugs and controlling invasive species growth. The riparian
restoration efforts along the project streams will be adjacent to reconstructed stream banks and will
extend from a minimum of 50 feet to a maximum of 200 feet from top of bank. The riparian restoration
efforts along the two project ditches will extend to 200 feet from the top of bank.
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 4.0 of the preliminary design
plans located in the Appendix. The plans also contain information on planting zones on Sheets 4.1‐4.3.
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 riparian 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 and wetland construction, as necessary. This will be followed by an appropriate
permanent seed mixture. Planting is scheduled for fall 2018.
3.3 Riparian Preservation Activities
Riparian buffer preservation will include permanently protecting existing forested riparian areas with a
conservation easement. The small 0.33‐acre forested area is in the north‐eastern portion of the project
along Grantham Branch (Figure 5)
Grantham Branch Mitigation Bank Parcel
HUC 03020201 – BPDP 6
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. One hundred square meter
vegetation plots will be placed on 2% of the planted area of the riparian buffer and nutrient offset bank
site. The approximate location of the plots is shown on Figure 7. 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 12 vegetation
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. Some, but not all, of the
vegetation plots will be monitored for both the buffer/nutrient bank and the stream/wetland bank
(Figure 7). The plots will be randomly placed throughout the planted riparian areas.
Planting is scheduled for fall 2018. 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
planted trees per acre at the end of Year 5. Appropriate native volunteer stems of native hardwood tree
species may be included to meet the performance standards upon DWR approval
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
In the event that the Parcel or a specific component of the Parcel fails to achieve the success criteria
outlined in Section 4.1, adaptive measures will be developed, or appropriate remedial actions will be
implemented. Site maintenance will be performed to correct any identified problems on the Parcel that
have a likelihood of affecting project success. Such items include, but are not limited to, fire, flooding,
drought, or insects that cause excess tree mortality. 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 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 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 Neuse buffers to
ensure that no buffer violations will occur.
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,
Grantham Branch Mitigation Bank Parcel
HUC 03020201 – BPDP 7
damaged, or destroyed will be repaired and/or replaced on an as needed basis. Contact information for
Wildlands Holdings III, LLC and the long‐term steward will be provided on boundary markers throughout
the site.
5.0 Financial Assurance
Following approval of the Grantham Branch 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 68.78 acres will be protected with a permanent conservation easement. After applying
credit ratios and percentages of full credit, the Grantham Branch Parcel includes approximately 15.16
creditable acres. Out of the 15.16 creditable acres, approximately 10.80 acres (470,448 ft²) of riparian
restoration on agriculture fields will be used to generate Neuse riparian buffer credit, approximately
4.03 acres (9,160.27 lbs.‐Nitrogen) of riparian restoration on agriculture fields will be used to generate
nutrient offset credits, and approximately 0.33 acres of riparian areas will be preserved for Neuse
riparian buffer credit. The Sponsor may use the 10.80 acres of riparian restoration mentioned above for
either riparian buffer credit or nutrient offset credit, but not both. The remaining 53.62 acres within the
Conservation Easement, will be used for wetland and stream mitigation pursuant to the Wildlands
Holdings III, LLC Grantham Branch Stream & Wetland Mitigation Bank (USACE ID 2017‐00549) (Figure 6).
These acres will not be used to generate riparian buffer or nutrient offset credits.
The Sponsor must request and receive approval from DWR prior to any credit conversions and transfers
to the credit ledgers. With each 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.
Mitigation activities per drainage Feature are outlined in Table 6. These acreages were calculated prior
to applying any reductions in riparian buffer credits for areas between 101 feet and 200 feet from top of
bank, per 15A NCAC 02B.0295(n) or the 10:1 credit ratio on the preservation of rural streams, per 15A
NCAC 02B.295(m).
The Sponsor will maintain three credit ledgers. One to account for buffer restoration credits, one to
account for buffer preservation credits and one to account for Nitrogen nutrient offset credits. Overall
