Bank Parcel Development Package
Perry Hill II
Neuse River Basin
1.0 Introduction
The Perry Hill II Mitigation Bank Parcel ("Parcel") is proposed under the terms and conditions of the
Perry Hill II Nutrient Offset and Buffer Mitigation Banking Instrument ("MBI"), made and entered into by
Wildlands Holdings V, LLC acting as Bank Sponsor ("Sponsor") and the North Carolina Department of
Environmental Quality ("NCDEQ") Division of Water Resources ("NCDWR"). The Parcel shall be planned
and designed according to the MBI, 15A NCAC 026 .0240 and the Consolidated Buffer Mitigation Rule
15A NCAC 026 .0295 which became effective November 1, 2015.
The Parcel is in Orange County approximately three miles northwest of Hillsborough, NC, immediately
adjacent to the proposed North Carolina Division of Mitigation Services ("NCDMS") Perry Hill Mitigation
Site, NCDWR Project Number 2019-0157 ("NCDMS Site") (Figure 1). The Parcel expands the NCDMS
Site's protected riparian area from 100 feet in the NCDMS Site to 100-200 feet on along Perry Branch,
three unnamed tributaries and two ephemeral channels. The primary purpose of the project is to
provide riparian buffer mitigation credits and nutrient offset credits to compensate for unavoidable
impacts in the Neuse River Basin 03020201 Hydrologic Unit Code ("HUC")within the Falls Lake
Watershed (Figure 2).
1.1 Parcel Location and Description
The Parcel is located within the Falls Lake Watershed of the Neuse River Basin HUC 03020201030020 and
North Carolina Division of Water Resources (DWR) Subbasin 03-04-01 in Orange County. To reach the
site, traveling west on 140/85 from Raleigh/Durham, follow 140/85 to exit 161 for US-70 Connector North.
Take a right at the bottom of the ramp and continue onto US-70 East (1.0 mile) via US-70 Connector North.
Continue on US-70E (1.9 miles) before taking a left onto Faucette Mill Rd. Continue (1.9 miles) and take a
sight right onto Frank Perry Road. The Parcel will be on right (0.5 miles).
Perry Branch and the three unnamed tributaries on the Parcel flow directly to Corporation Lake, a water
supply reservoir on the Eno River. The Eno River is classified as water supply waters (WS-II) and nutrient
sensitive waters (NSW). The Eno River subsequently flows to Falls Lake, which is also classified as water
supply waters (WS-IV) and NSW. All water supply waters are considered high quality waters (HQW) by
supplemental classification. In addition, all waters in the Neuse River Basin are classified as NSW which is
a supplemental classification intended for waters needing additional nutrient management due to being
subject to excessive growth of microscopic or macroscopic vegetation.
The proposed project supports specific goals identified in the following watershed management plans.
The 2009 Neuse River Basinwide Water Quality Plan lists major stressors in Subbasin 03-04-01 to be total
suspended solids (T55), nutrients, and chlorophyll a (NCDENR, 2009). The 2010 Neuse River Basin
Restoration Priorities (RBRP) highlights the importance of riparian buffers for stream restoration projects
(NCEEP, 2010). Riparian buffers retain and remove nutrients and suspended sediments. Of the 123 miles
of streams in the Middle Eno River watershed (03020201030030), 23% do not have adequate riparian
buffers. The RBRP states that "priority [restoration] projects should increase or improve buffers." The
RBRP also states that a goal for the Neuse 01 is to, "...promote nutrient and sediment reduction in
agricultural areas by restoring and preserving wetlands, streams, and riparian buffers." Another goal for
the Neuse 01 is to support the Falls Lake Watershed Management Plan.
WPerry Hill II Bank Parcel Development Package
HUC 03020201 Page 3 May 2020

This riparian mitigation project will reduce sediment and nutrient loading and improve terrestrial habitat.
The area proposed for restoration and enhancement via cattle exclusion is currently a mixture of active
livestock pasture with isolated forested areas. Existing conditions photos are included in Appendix A. By
removing livestock access and restoring the vegetation on the areas up to 200 feet from the streams and
ephemeral channels; the project will reduce nutrient and sediment inputs to project streams and
downstream receiving waters. The restored floodplain areas will filter nutrient and sediment during high
rainfall events. Additionally, invasive vegetation will be treated within the project area and the new native
vegetation will provide cover and food for wildlife.
2.0 Mitigation Project Summary
2.1 Project Goals
The major goals of the proposed buffer and nutrient mitigation project are to provide ecological and water
quality enhancements to the Falls Lake Watershed in the Neuse River Basin by creating a functional
riparian corridor and restoring the buffers. Specific enhancements to water quality and ecological
processes are outlined below in Table 1.
Table 1: Ecological and Water Quality Goals
Goal
Objective
Exclude livestock from the Parcel
Exclude livestock from the conservation easement areas by
installing fencing around the Parcel.
Nutrient input will be decreased by removing livestock
access. The off -site nutrient input from adjacent livestock

fields and row crops will also be absorbed on -site by
filtering downslope runoff through the restored upland
and floodplain vegetation areas.
Sediment from upslope sources will be captured by
Decrease sediment input
deposition on the restored buffer areas where native
vegetation will slow overland flow velocities.
Create appropriate terrestrial habitat
Buffer areas will be restored by planting native vegetation
and removing invasive vegetation.
Permanently protect the Parcel from harmful uses
A conservation easement will be recorded on the Parcel.
2.2 Existing Parcel Conditions
The Parcel is approximately 14.57 acres and primarily consists of active livestock pasture along Perry
Branch, three unnamed tributaries (UT1, UT2, and UT3), and two ephemeral channels (EC1 and EC3).
Currently livestock have access to all project streams and ephemeral channels but the first 100 feet from
top of bank will be restored or enhanced via cattle exclusion as part of the NCDMS Site. The Parcel expands
beyond that boundary increasing buffer widths up to 200 feet.
In general, this area has maintained its rural, farming character over the last 81 years with only minor
changes in land cover. Historical aerials of the Parcel area included in Appendix B. This consistency in land
use within the project watershed indicates that watershed processes affecting hydrology, sediment
supply, and nutrient and pollutant delivery have not varied widely over this time period. With a lack of
developmental pressure, watershed processes and stressors from outside the project limits are likely to
remain consistent throughout the implementation, monitoring, and closeout of this project.

Per the On -Site Stream Evaluation and Determination issued by NCDWR on April 16, 2019 (see the
Appendix C), the Parcel contains one perennial stream Perry Branch; three intermittent streams UT1, UT2,
and UT3; and two ephemeral channels EC1 and EC3. Perry Branch is a headwater system that originates
onsite immediately down valley from a riparian non-riverine wetland and flows southwest. UT1, UT2, and
UT3 are all intermittent streams that flow southeast to Perry Branch. The ephemeral channels, EC1 and
EC3, flow southeast as well until they become intermittent streams at the start of UT1 and UT3,
respectively. All the streams and channels included in this project originate onsite (Figure 3).

2.3 Site Viability for Buffer Mitigation and Nutrient Offset Mitigation
NCDWR performed an onsite visit to determine viability for buffer and nutrient offset mitigation on
February 25, 2019 (letter dated April 16, 2019) for the project. Four of the six features assessed were
deemed viable by NCDWR to generate buffer mitigation. EC1 and EC3 required more information under
15NCAC 02B .0295(o)(7) to be viable. The additional information to support buffer mitigation credit
viability on the two ephemeral channels is included in Section 2.4.
There have not been any changes to the land use in the project area since the February 25th DWR site
visit. Construction on the NCDMS Site has not started. A copy of the "Site Viability for Buffer Mitigation &
Nutrient Offset" letter from DWR is included in Appendix C and summarized in Table 3.

2.4 Alternative Mitigation
In addition to buffer restoration on subject streams, per the Consolidated Buffer Mitigation Rules (15A
NCAC 02B 0.0295 (o), alternative mitigation is proposed on the Parcel in the form of buffer restoration on
ephemeral channels and enhancement via cattle exclusion. The proposed project complies in the
following ways:
Restoration on Ephemeral Channels 15A NCAC 026 .0295 (o)(7):
• The ephemeral channel is directly connected to intermittent or perennial stream channels and
will be protected under the same contiguous easement boundary (See Figure 3 for Parcel
easement boundary and NCDMS easement boundary).
• The area of the mitigation site on ephemeral channels does not compromise more than 25
percent of the total area of buffer mitigation (See Table 7 for credit calculations).
• The mitigation area on the Parcel's ephemeral channels is located completely within its drainage
area (See Figure 5 for watershed boundaries).
Enhancement via Cattle Exclusion 15A NCAC 026 .0295 (o)(6)
• Livestock is permanently excluded from riparian area (See Figure 7 for proposed fence
boundary).
• Grazing must be the predominant land use since the effective date of the applicable buffer rule
(See Appendix B for historical aerials documenting land use)
2.5 Watershed Characterization
The Parcel is located within the Targeted Local Watershed 03020201030020 and DWR Subbasin 03-04-01.
The Parcel contains tributaries which flow directly to Corporation Lake, a water supply reservoir on the
Eno River, then on to Falls Lake. The Eno River is classified as water supply waters (WS-II) and nutrient
sensitive waters (NSW) and Falls Lake is classified as water supply water (WS-IV) and NSW. All water supply
waters are considered high quality waters (HQW) by supplemental classification. In addition, all waters in
the Neuse River Basin are classified as NSW which is a supplemental classification intended for waters
needing additional nutrient management due to being subject to excessive growth of microscopic or
macroscopic vegetation.
The Parcel topography and relief are typical for this region, as illustrated on the Hillsborough and Efland,
NC USGS 7.5-minute topographic quadrangles (Figure 4). The majority of the streams at the Parcel have
gently sloped alluvial valleys that vary in width throughout the project area. UT1 and EC1 include a
steeper, more confined valley than the other project reaches. Drainage areas for the project reaches
(Figure 5) were delineated using Stream Stats and contour intervals derived from the North Carolina
Floodplain Mapping Program's 2007 Light Detection and Ranging (LiDAR) data. Land uses draining to the
project reaches are a mix of active pastures, fields, and woodlands. The watershed areas and current land
use are summarized in Table 4.

2.6 Soils
The proposed project is mapped by the Orange County Soil Survey. Project area soils are described
below in Table 5. Most of the stream reaches are on Georgeville silt loam soils, with Enon loam, Iredell
gravelly loam, and Lignum silt within the upper reaches. Enon loam underlies UT2; Iredell gravelly loam
underlies UT3; and Iredell gravelly loam and Lignum silt underlies the headwaters of Perry Branch. Perry
Branch, UT1. UT2, UT3, EC1, and EC3 are all depicted on the 1977 NRCS Soil Survey provided in Figure 6.

2.6 Geology
The Parcel is in a portion of the Piedmont known as the Carolina Slate Belt (NCGS, 1985). The rocks in this
region are primarily volcanic and sedimentary rocks that underwent low-grade metamorphism giving
them a slaty cleavage. Coarse -grained intrusive granites comprise the rest of the Slate Belt rocks (Rogers,
2006). The geology of this area has important effects on the Parcel hydrology, hydraulics, geomorphology,
and sediment transport. Streams in the Carolina Slate Belt tend to go dry during late summer and early
fall as a result of geologic, topographic, and climatic factors. A study by Giese and Mason states that the
"Carolina slate belt has among the lowest potential for sustaining baseflow in streams" throughout the
year as compared to other regions of North Carolina. Median low flows in the Carolina Slate Belt, defined
by the study as the 7Q10 (7-day consecutive low flow with a 10-year return frequency, or the lowest
stream flow for seven consecutive days that would be expected to occur once in ten years), can be as low
as 0.005 ft3/s/mi2 of drainage area (Giese and Mason, 1993).
2.7 Existing Vegetative Communities
The existing vegetation within the Parcel consist of actively grazed fields dominated by pasture grasses
such as fescue (Festuca spp.) and isolated scattered trees.
2.8 Threatened and Endangered Species
The NC Natural Heritage Program (NHP) database and the US Fish and Wildlife Service (USFWS) database
were searched for federally listed threatened and endangered plant and animal species in Orange County,
NC. The Orange County listed endangered species includes the dwarf wedgemussel (Alasmidonta
heterodon), Michaux's sumac (Rhus michauxii), and smooth coneflower (Echinacea laevigata), all of which
are endangered, and the Atlantic pigtoe (Fusconaia masoni), which is listed as proposed threatened.
A pedestrian survey conducted on August 14, 2018, indicated that the Parcel did not provide suitable
habitat for the dwarf wedgemussel. The pedestrian survey did indicate that the Parcel provides suitable
habitat for the Atlantic pigtoe, smooth coneflower, and Michaux's sumac but no species were identified
on the Parcel. Therefore, due to the absence of the listed species on the Parcel, the project has been
determined by Wildlands to have "no effect" on the smooth coneflower and Michaux's sumac. Poor water
quality has resulted from the active cattle farm and due to this and the absence of the Atlantic pigtoe on
the Parcel, the project has been determined to "may affect, but not likely to adversely affect" the Atlantic
pigtoe. The project will have "no effect" on the dwarf wedgemussel due to the absence of suitable habitat.
Per the United States Fish and Wildlife Service (USFWS) Raleigh Field Office standard, Wildlands submitted
a Self -Certification Letter. The Self -Certification Letter states the USFWS does "concur with the "no effect"
or "not likely to adversely affect" determinations for proposed and listed species and proposed and
designated critical habitat; additional coordination with this office is not needed. USFWS had no additional
comment during the thirty -day review period. All documents and correspondence submitted to the
USFWS are included in Appendix C.

HUC 03020201 Page 8 May 2020

2.9 Cultural Resources and Significant Natural Heritage Areas
There are no existing structures in the project area. The Parcel is not located near any locations listed on
the National Register with the State Historic Preservation Office (SHPO). SHPO was contacted in a letter
dated February 18, 2019 and subsequently responded in a letter dated April 2, 2019 which stated there
were no concerns or comments on the project site. Correspondence with SHPO is enclosed in Appendix
C.
2.10 FEMA Floodplain Compliance
Perry Branch and the unnamed tributaries are within Zone X, an area of minimal flood hazard. The Site
location is included on the Orange County Flood Insurance Rate Map Panel 9865. The map's effective date
is February 2, 2007. Portions of the Parcel are located in Zone X, no modeling or map revisions will be
required. Wildlands will coordinate with Orange County to obtain a floodplain development permit, if
necessary.
2.10 Site Location, Constraints, and Access
The Parcel is in central Orange County approximately three miles northwest of Hillsborough, NC and is
located within the Neuse River Basin HUC 03020201030020 and DWR Subbasin 03-04-01 (Figure 1).
The Parcel is accessible via two existing farm roads from Frank Perry Road. An overhead transmission line
is located at the downstream extent of Perry Branch. The proposed easement abuts the existing overhead
utility easement. Three crossings are proposed to support on -going farming activities. No buffer credit is
claimed within the proposed crossing location (Figure 7). There are no other known constraints on or
adjacent to the Parcel.
2.11 Other Environmental Conditions
An EDR Radius Map Report with Geocheck was ordered for the Parcel through Environmental Data
Resources, Inc. on August 13, 2018. Neither the target property nor the adjacent properties were listed in
any of the Federal, State, or Tribal environmental databases searched by EDR. In 1991 there was one
leaking above ground storage tank documented 0.47 miles from the Parcel. The incident was reported
and cleaned up by excavating the contaminated soil. Based on the location from the Parcel, it was
determined that there is no evidence of any "recognized environmental conditions" in connection with
the target property. The EDR report is included in Appendix D.
3.0 Site Protection Instrument
The land required for buffer planting, management and stewardship of the mitigation project includes
portions of the parcel listed in Table 6. The Parcel will remain in private ownership, protected in its entirety
by an approved DWR long-term steward and will be managed under the terms detailed in an approved
DWR conservation easement.

4.0 Mitigation Work Plan
The project will restore agriculturally impacted land along Perry Branch, UT1, UT2, UT3, EC1, and EC3 on
the Parcel to a protected riparian corridor, improving the ecological function of the area. The project
design will ensure that no adverse impacts to wetlands or existing riparian buffers occur. Figure 7
illustrates the conceptual design for the Parcel. Figure 8 further depicts the riparian buffer zones for the
Parcel. Sections 4.1 through 4.4 provide more detailed descriptions of the proposed buffer mitigation
activities. The Parcel is scheduled to be constructed concurrently with the NCDMS Site.
4.1 Parcel Preparation
The land use within the Parcel has been maintained as cleared livestock pasture except for a few small
forested areas. Vegetative restoration areas will require little site preparation due to the land being open
pasture. Site preparation may include select herbicide treatments and/or limited mechanical clearing to
remove undesirable vegetation. If needed, invasive species will be selectively removed and/or spot
treated by a licensed pesticide applicator.
4.2 Riparian Area Restoration Activities
Riparian restoration will involve planting appropriate native tree species along the riparian corridor.
Vegetation management and herbicide applications may be needed over the first few years of tree
establishment to prevent encroachment of undesirable species that may out -compete the planted native
vegetation. The specific species composition to be planted is based on the desired community type,
observation of occurrence of species in riparian buffers adjacent to the Parcel, and best professional
judgement on species establishment and anticipated site conditions in the early years following project
implementation. Tree species planted across the riparian areas of the Site will include a mixture of the
following species: American sycamore (Platanus occidentalis), river birch (eetula nigra), black gum (Nyssa
sylvatica), eastern cottonwood (Populus deltoids), black willow (Salix nigra), silky willow (Salix sericea),
elderberry (Sambucus canadensis), buttonbush (Cephalanthus occidentalis), silky dogwood (Corpus
amomum), overcup oak (Quercus lyrata), swamp chestnut oak (Quercus michauxii), southern red oak
(Quercus falcata), northern red oak (Quercus rubra), white oak (Quercus alba), hop hornbeam (Ostrya
virginiana), sourwood (Oxydendrum arboreum), tag alder (Alnus serrulata), winged elm (Ulmus alata),
American elm (Ulmus americana), red maple (Acer rubrum), pawpaw (Asimina triloba), persimmon
(Diospyros virginiana), possumhaw viburnum (Viburnum nudum), boxelder (Acer negundo), flowering
dogwood (Corpus floridus), sugarberry (Celtis laegivata), American beech (Fagus grandifolia), ironwood
(Carpinus caroliniana), sweetshrub (Calycanthus floridus), arrowwood viburnum (Viburnum dentatum),
and painted buckeye (Aesculus sylvatica).
Trees will be planted at a density sufficient to meet the performance standards outlined in the Rule 15A
NCAC 02B .0295 of 260 planted trees per acre at the end of monitoring. No one tree species will be greater
than 50% of the established stems. Planting is scheduled for February 2021.
4.3 Riparian Area Enhancement via Cattle Exclusion Activities
Permanent boundary fencing will exclude livestock from the buffer enhancement areas as outlined in Rule
15A NCAC 02B .0295(o)(6). The enhancement via livestock exclusion area will be protected in perpetuity
under a conservation easement. Planting within the enhancement areas will be limited to severely
degraded forested areas that currently exhibit low woody vegetation (stem) densities. A seed mix will be
applied where livestock have created bare soil and sufficient sunlight is available to support the species
in the seed mix. Planting and fencing will happen in conjunction with the Perry Hill Full Delivery Mitigation
Site.
WPerry Hill II Bank Parcel Development Package
HUC 03020201 Page 10 May 2020

4.4 Riparian Area Preservation Activities
No buffer preservation activities are planned for the Parcel.
5.0 Monitoring and Maintenance Plan
5.1 Monitoring Protocol
Permanent vegetation monitoring plots will be installed and evaluated within the Parcel to measure the
survival of the planted trees. A total of 11 plots will be randomly placed throughout the planted areas
(Figure 9). The size of individual quadrants will be 100 square meters.
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 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.
Visual assessments of the enhancement area will be performed on a semi-annual basis during the
monitoring period. Problem areas with vegetative health will be noted (e.g. low stem density, vegetation
mortality, invasive species or encroachment). Visual assessments will include documenting the condition
of livestock exclusion fencing and that no livestock are accessing the conservation easement area.
Planting is scheduled for February 2021. 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 measure of
vegetative success for the Parcel will be the survival of at least four native hardwood tree species, where
no one species is greater than 50% of the established planted stems, and an established density of at least
260 planted trees per acre at the end of monitoring year five. Appropriate and desirable native volunteer
species may be included in the density to meet the performance standards with DWR approval.
The Sponsor shall submit the annual monitoring report to DWR by December 31" of each year for five
consecutive years and will follow the terms and conditions of the Perry Hill II Mitigation Banking
Instrument (MBI).
5.2 Parcel Maintenance
If the Parcel or a specific component of the Parcel fails to achieve the success criteria outlined in Section
5.1, adaptive measures will be developed and/or appropriate remedial actions will be implemented.
Parcel 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, 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 herbicide schedule may 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. Herbicides used on the Parcel
will be applied in accordance with North Carolina Department of Agriculture rules and regulations.
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, post, tree -blazing, or other means as
allowed by site conditions and/or conservation easement. Contact information for the conservation
easement holder will be included on easement markers. Boundary markers that have been disturbed,
WPerry Hill II Bank Parcel Development Package
HUC 03020201 Page 11 May 2020

damaged, or destroyed will be repaired and/or replaced on an as needed basis. The easement boundary
will be checked annually as part of monitoring activities.
Easement boundary 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 from DWR prior to conducting any mowing activities within Zone 1
and Zone 2 of the Neuse buffers to ensure that no buffer violations have occurred.
6.0 Financial Assurance and Long -Term Management
6.1 Financial Assurances
Following approval of Perry Hill II Bank Parcel Development Package, 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
Bank Parcel Development Package, but not less than $150,000.00. In lieu of posting the performance
bond, the Sponsor may elect to plant the project prior to the first credit release. In that case no
performance bond will be necessary.
After completion of the planting, 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 and 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 at least annually 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.
6.2 Long -Term Management
The Parcel will remain in private ownership, protected in its entirety by an approved DWR long-term
steward and will be managed under the terms detailed in an approved DWR conservation easement. The
long-term steward will be responsible for periodic inspection of the Parcel to ensure that the restrictions
documented in the recorded easement are upheld in perpetuity.
7.0 Mitigation Potential
Of the 14.57 acres protected under the conservation easement, the mitigation activity for 13.91 acres is
riparian restoration with 0.46 acres being proposed for buffer restoration credit and 13.45 acres being
proposed for nutrient offset mitigation credit. There is also 0.49 acres of buffer enhancement, via cattle
exclusion within the conservation easement proposed for riparian buffer credit. The mitigation credit
calculations were derived based on Wildlands' conceptual design for maximum ecological uplift. The
management objectives, mitigation type, and proposed amount of buffer mitigation are presented in
Tables 7 and 8, below. The riparian restoration areas are viable for either nutrient offset credits or riparian
buffer credits and can be converted upon approval by NCDWR if within the first 100 feet from top of bank.
