Bank Parcel Development Package
North Fork Little River Nutrient Offset and Buffer Mitigation Bank Parcel
Falls Lake Watershed in the Neuse River Basin
The North Fork Little River Nutrient Offset and Buffer Mitigation Bank Parcel ("Parcel") is proposed
under the terms and conditions of the Wildlands North Fork Little River Nutrient Offset and Buffer
Mitigation Banking Instrument (MBI), made and entered into by Wildlands Holdings II, LLC, acting as
Bank Sponsor (Sponsor), and the North Carolina Department of Environmental Quality (NCDEQ) on April
19, 2016. The Parcel shall be planned and designed according to the MBI, 15A NCAC 026.0240 and the
Consolidated Mitigation Rule 15A NCAC 026.0295 which became effective on November 1, 2015.
The project encompasses land along unnamed tributaries to the North Fork of the Little River in Durham
County, NC. One purpose of the Bank is to provide riparian buffer mitigation credits to compensate for
unavoidable buffer impacts in the 03020201 Hydrologic Unit Code of the Neuse River Basin as depicted
in Figure 1. The second purpose of the Bank is to provide nutrient offset credits for stormwater
requirements with new and existing development requiring nitrogen and phosphorous offsets within the
Falls Lake Watershed as depicted in Figure 1.
1.0 Project Location and Description
1.1 Introduction
The Parcel involves restoring Neuse riparian buffers and other riparian areas adjacent to streams and
ditches onsite in order to help reduce non -point source contaminant discharges to downstream waters
in the Falls Lake Watershed. Approximately 33.4 acres of the project area will be protected with a
permanent conservation easement. Out of the 33.4 acres, 13.9 acres of riparian areas will be restored
for Neuse riparian buffer credit and 18.4 acres (41,823.56 lbs. -N and 2,693.76 lbs. -P) of riparian areas
will be restored for nutrient offset credit. One point one (1.1) acres will not generate mitigation credit
(0.4 acre of stream, 0.3 acre of ditch, 0.2 acre does not qualify for mitigation credit due to distance from
project features, 0.2 acre does not qualify for mitigation credit due to lack of diffuse flow entering the
feature).
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 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 200 feet for
nutrient offset credits.
1.2 Parcel Location
The Parcel is located in northwestern Durham County, approximately 14 miles north of the City of
Durham (36° 10' 9.48" N and 78° 55'49.44" W) in a rural watershed within the Neuse River Basin (HUC
03020201) and within Division of Water Resources (DWR) sub -basin 02-00-10. To get to the Parcel from
downtown Durham, travel north on U.S. Highway 501 North for approximately 12.7 miles. Turn left onto
S. Lowell Road and continue west for approximately 1.9 miles to the intersection with Johnson Mill
Road. The Parcel will be on the north side of S. Lowell Road at this intersection (Figure 2).
North Fork Little River Mitigation Site
HUC 03020201— BPDP

2.0 Project Area - Existing Conditions
2.1 Parcel Features
The project includes restoring the riparian areas along eight identified features (A -H): three unnamed
tributaries to the North Fork of the Little River and five ditches (Figure 3). All Parcel features flow into
unnamed tributary Feature A, which then flows into another unnamed tributary to the North Fork of the
Little River, the Little River, the Little River Reservoir, the Eno River, and ultimately into Falls Lake. All of
the intermittent streams on the Parcel are classified as Nutrient Sensitive Waters (NSW) by DWR. The
Little River Reservoir is a major source of drinking water for the City of Durham; Falls Lake is a major
source of drinking water for the City of Raleigh. To protect these reservoirs, the Little River and its
waters are also classified as Water Supply II (WS -II) and as a High Quality Water (HQW) by DWR.
DWR performed a stream determination on the site which is documented in a Stream Determination
Letter dated August 5, 2013. Per the Letter, Features A, D, and E are classified as intermittent streams
and Features B, C, F and G are classified as ditches (Appendix). Feature H was classified as a ditch by
DWR staff during a July 9, 2015 site visit. Feature A is shown as a blue line on the Rougemont USGS 7.5'
Quadrangle map (Figure 2).
DWR visited the Parcel to assess the viability of implementing a buffer and nutrient offset bank. The
results are documented in a Site Viability Letter dated December 16, 2015. Per the letter, features A, D,
and E are viable for riparian restoration and suitable for either buffer mitigation or nutrient offset
credits (Appendix). Features B, C, F, G, and H are also viable for buffer mitigation or nutrient offset
credits assuming they comply with 15A NCAC 026.0295 (o)(8)(A-E). The Buffer Interpretation
/Clarification Memo #2008-019 applies to Features H and F where maintenance of diffuse flow onsite is
unattainable.
Photos showing site conditions of the Parcel at the time the BPDP was submitted are provided in the
appendix. Figures 3, 4 and Table 5 demonstrate how four of the five features are in compliance with the
five components of this rule. Features B, F, G, and H (Feature C does not satisfy item six, below):
1. Directly connect with and drain towards intermittent streams (Features A, D, or E);
2. Are contiguous with the rest of the mitigation site and will be protected under a conservation
easement;
3. Receive overland stormwater runoff;
4. Are between one and three feet in depth (depths are outlined on Figure 3 and included in the
appendix); and
5. Were in place prior to the effective date of the buffer rule (see Figure 4, a 1976 Durham County
Soils Survey that depicts the features).
6. The watershed draining to the ditch shall be at least four times larger than the restored areas
along the ditch.
2.2 Parcel Soils
The soils on the Parcel are mapped by the Durham County Soil Survey. There are four main soil types on
the Parcel: Georgeville silt loam, Lignum silt loam, Mecklenburg loam, and Wehadkee silt loam. These
soils are described below in Table 1. The 1976 Soils Survey Map is provided in Figure 4.

2.3 Existing Vegetative Communities
Parcel vegetation consists primarily of open agricultural fields in row crop production for corn. The
Parcel streams and ditches have little to no existing riparian buffer. The riparian area adjacent to most of
the Parcel streams and ditches are mowed annually.
While the Parcel consists of agricultural fields, there are some forested areas on the opposite site of S.
Lowell Road. The nearby forested areas were assessed on December 18, 2015, for existing vegetation
conditions. This area is dominated by sweetgum (Liquidambarstyraciflua) but contains some loblolly
pine (Pinus taeda), black willow (Salix nigra), red maple (Acer rubrum), and sycamore (Platanus
occidentalis). This forested area is generally characterized as a Piedmont Bottomland Forest, according
to the North Carolina Natural Heritage Program (NHP) classification system (Schafale, 2012).
2.4 Threatened and Endangered Species
The US Fish and Wildlife Service (USFWS) database was searched for federally listed threatened and
endangered plant and animal species for Durham County, NC. Three federally listed species, the bald
eagle (Haliaeetus leucocephalus), Michaux's sumac (Rhus michauxii), and the smooth coneflower
(Echinacea loevigato), are currently listed in Durham County (Table 2).

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 January 11, 2016.
SHPO responded on February 4, 2016, and stated they "are aware of no historic resources which would
be affected by the project". All correspondence is included in the Appendix.
2.6 Environmental Issues
An EDR Radius Map Report with Geocheck was ordered for the Parcel through Environmental Data
Resources, Inc. on October 31, 2013. 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.
2.7 FEMA Floodplain / Floodway Mapping
The Parcel is not located with the Federal Emergency Management Association's (FEMA's) designated
floodway or approximate 100 -year flood boundary. No floodplain impacts associated with the Parcel are
anticipated.
3.0 Proposed Neuse Buffer and Nutrient Offset Restoration Plan
Actions required to develop the Parcel for mitigation will require altering current land use practices.
Both the Neuse buffer and the nutrient offset restoration areas will involve replanting appropriate
native tree species along the project corridors. Intensive vegetation management and a rigorous
herbicide schedule will need to be implemented over the first few years of tree establishment in the
restoration areas to prevent establishment of invasive species that will attempt to out -compete the
planted native vegetation. More detailed descriptions of the proposed restoration activity follow in
Sections 3.1 and 3.2.
3.1 Parcel Preparation
The majority of the Parcel slated for Neuse buffer or nutrient offset restoration has been maintained as
a cleared agricultural field. These areas will require little site preparation other than select herbicide
treatments or limited mechanical clearing to remove undesirable underbrush prior to planting. The
restoration area will be planted using hand labor with dibble bars or other acceptable forestry practices.
Site preparation and planting is planned to begin in January 2017.
3.2 Planting
The revegetation plan for the site will include planting bare root trees and controlling invasive species
growth. Bare root trees selected for the Parcel will be native bottomland hardwood species typical for
Piedmont Bottomland Hardwood communities as defined by Schafale (2012). Trees will be planted at a
density sufficient to meet the success criteria set forth in the Mitigation Banking Instrument (MBI) of 260
trees per acre at the end of five years. Tree species specified for planting on the North Fork Little River
site are detailed in Table 3. All willow oaks will be planted along the stream banks or top of bank as long
as soil type and hydrology make for suitable conditions to promote growth and survivability. An
appropriate seed mix will also be applied to provide temporary ground cover for soil stabilization and
reduction of sediment loss during rain events. Planting is scheduled for January 2017.

4.0 Monitoring and Maintenance Plan
4.1 Monitoring Protocol
Vegetation monitoring plots will be installed and evaluated within the restoration areas to measure the
survival of the planted trees. The number of monitoring quadrants required was determined in
accordance with the Carolina Vegetative Sampling Protocol (CVS) Levels 1 & 2. A total of 27 plots will be
established within the credit generation area. The size of individual quadrants will be 10 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 27 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 2017. The first annual monitoring activities will commence at the end
of the first growing season, at least five months after planting has been completed. Species composition,
density, and survival rates will be evaluated on an annual basis by plot and for the entire site. The
Sponsor shall submit an annual monitoring report to DWR by December 31' of each year for five
consecutive years and will follow the terms and conditions of the MBI. Success criteria within the Neuse
buffer and nutrient offset restoration areas will be based on the survival of a minimum density of 260
planted stems per acre after five years of monitoring.
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 over the first few years of tree establishment in the restoration
areas to prevent establishment of invasive species that will attempt to out -compete the planted native
vegetation. The only herbicides used on the Parcel will be aquatic approved herbicides and will be
applied in accordance with North Carolina Department of Agriculture rules and regulations.
5.0 Financial Assurance
Following approval of the North Fork Little River 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 approved
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.
North Fork Little River Mitigation Site
HUC 03020201— BPDP

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.
6.0 Mitigation Potential
Approximately 33.4 acres of land will be protected with a permanent conservation easement. Out of the
33.4 acres, 13.9 acres will be restored for Neuse buffer credit and 18.4 acres will be restored for nutrient
offset credit. One point one (1.1) acres will not generate mitigation credit (0.4 acre of stream, 0.4 acre
of ditch, 0.2 acre does not qualify for mitigation credit due to distance from project features, and 0.2
acre does not qualify for mitigation credit based on lack of diffuse flow). The North Fork Little River
Parcel will generate a total of 18.4 acres (41,823.56 lbs -Nitrogen and 2,693.76 lbs- Phosphorus) of
nutrient offset credits. Additionally, it will also generate 13.9 acres (605,484 ft2) of Neuse buffer credits.
Credit generating mitigation activities per drainage feature is outlined in Table S. Overall credit
generation on the Parcel is summarized in Table 6.
The Sponsor may use the 13.9 acres (605,484 ft2) for either Neuse buffer credits or nutrient offset
credits, but not both. 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.

Re: Site Viability for Buffer Mitigation & Nutrient Offset — North Fork Little River
10114 S. Lowell Rd, Bahama, NC
Durham County
Dear Jahn,
On June 13, 2013, Katie Merritt, with the Division of Water Resources (DWR), received a
request from you on behalf of Wildlands Engineering Inc., for a site visit near the above -
referenced site in the Upper Falls Watershed to determine the potential for nutrient offset and
Neuse riparian buffer mitigation. On July 9, 2015, Ms. Merritt performed a stream buffer
determination and site assessment of the features onsite, which is more accurately shown in the
attached aerial signed by Ms. Merritt on August 5, 2013. If approved, mitigating this site could
provide riparian buffer credits and/or nutrient offset credits within the 8 -digit Hydrologic Unit
Code 03020201 of the Upper and Lower Falls Lake Watersheds.
Ms. Merritt°s evaluation of the features for buffer and nutrient offset mitigation pursuant to Rule
15A NCAC 02B.0295 (effective November 1, 2015) and. Rule 15A NCAC 02B.0240 is
provided below:
Features A, D and E
O Streams are subject to the Neuse Buffer Rule as determined by the stream buffer
determination letter issued for the subject site by the DWR on August 5, 2013.
• Land uses within the riparian areas (0 to +l- 200') adjacent to these streams were active
row crops. The riparian areas along these streams are viable for riparian restoration and
suitable for either buffer mitigation or nutrient offset credits.
• Features D and E connect with field ditches. Therefore, additional information will be
required to ensure that diffuse flow is restored and maintained.
Features_ B, C, F and G
• Features are ditches and are not subject to the Neuse Buffer rules 15A NCAC 02B .0233.
• The depth of each ditch was not evaluated onsite.

Land uses within the riparian areas (0 to +/- 200') adjacent to these ditches were active
row crops. The riparian areas along these streams are viable for riparian restoration and
suitable for either buffer mitigation or nutrient offset credits.
The direction of surface/storwater water flow within each ditch was not evaluated onsite.
Therefore, DWR will need to know details on flow direction within each ditch to the
streams. Features that are directly hydrologically connected to, and drain to the UTs
onsite are viable for riparian restoration to generate Nutrient Offset mitigation only.
A map showing the project site and the features is provided and signed by Ms. Merritt on August
5, 2015. For any areas depicted as not being viable for nutrient offset credit, one could propose a
different measure other than riparian restoration, along with supporting calculations and
sufficient detail to support estimates of load reduction, for review by the DWR to determine
viability for nutrient offset according to 15A N+C'AC 02B .0240, if proposing any ditch for
Neuse riparian buffer mitigation, the ditch must comply with all items listed in 15A NCAC 02B
.0295 (o) (8), which became effective on November 1 2015.
Please contact Katie Merritt at (919)-807-6371 if you have any questions regarding this
correspondence.
Sincerely,

RV. 1 he Dii isjon Of Water Qua Iity's (D WQ`s) stance on whether diffuse now of stormwater through the neo lvv restored buffers on
Mitigation sites should be a requirement. Diffuse Ilow is a requirement for buffer restoration or enhancement in the Neuse River
Basin Buffer Rule 15A ICAC 02B.0242(9)(d)(iii), the Tar -Pamlico River Basin Buffer Rule 15A NCAC 02B.0260(9)(d)(iii), and the
Catawba River Basin Buffer Rule 15A NCAC 02B.0244 (9)(d)(iii).
Diffuse now is a requirement for all sites in a buffered basin for buffer mitigation and for for sites providing nutrient offset credit as
well,
Current Policy! According to the Mitigation rules in the Neuse. Tar -Pamlico and Catawba buffer rules, a grading plan must be
provided for butler mitigation sites. In addition, those rules state that "The site shall be graded in a manner to ensure ditTuse flow
through the riparian buffer".
1Prnhlenu I he question has been raised as to whether stormwater carried by lateral ditches that enter buffered streams should provide
tlltluse Ito%% prior to that storinwater entering the restored hullers.
Solution: The Meuse, Tar -Pamlico and Catawba buffer rules with respect to buffer mitigation sites contain a very clear requirement
that states that diffuse now bf stormwater must be maintained through the buffer. Unless otherwise approved by DWQ, all buffer
mitivation sites must provide ditYuse flow of stormwater font ditches and similar conveyances through the restored butler.
Where such diffuse now cannot be attained and where DWQ agrees that such treatment is not possible, deduction of buffer credit will
lie calculated as follows:

A, B and C are angles. a, b, and c are distances (lengths)
DWQ believes that using an immediate drainage area extending at a 60 -degree angle from the point of discharge to the stream is a
reasonable approach to the issue of determining the area which is not draining through the restored buffer. To calculate the area of
buffer being "short-circuited" by the ditch, the area of the right triangles shown in the figure above must be determined..
a=50'
A=30
B = 60°
b=acot A
b = 50 (1,732)
b = 86,6' (87')
The area to be excluded from credit would be the area of the two right triangles:
Area = (a x b)12
Area = (50 feet x 87feet)12
Area = 2,175 SF
Total deducted area = 2,175 x 2 F 4,350 SF or 0.1 acres.
The example shown above assumes a buffer width of 50 feet from the tap of bank (riparian buffer mitigation site). For nutrient offset
sites, credit can be generated out to 200 feet from the top of bank. The policy applies to sites with larger buffers as follows:

Where a natural stream enters the project site, no deduction of credit will occur, Also, when a natural stream or a modified natural
stream flo,,v into a buffered stream, no deduction of credit wi1I occur. The modified natural stream must be subject to the buffer rules,
and must be verified to be a modified natural stream (as opposed to a ditch) through an on-site determination by DWQ personnel.
