1.0 INTRODUCTION
The Neville Farms Site (Site) presents 6.3 acres of permanent conservation easement in Orange County,
North Carolina. The purpose of this project is to generate Jordan Lake riparian buffer restoration and
preservation mitigation credits as well as nutrient offset credits. The Neville Farms Bank Parcel is included in
the Neville Farms Mitigation Banking Instrument (MBI) for Riparian Buffer Mitigation and Nutrient Offset
Credits signed between Watershed Investments NC, LLC and the NC Division of Water Resources (DWR)
on October 61h, 2015.This MBI is in accordance with 15A NCAC 02B .0295 (Temporary Consolidated Buffer
Mitigation Rule, effective October 24, 2014) and 15A NCAC 02B .0240 (Nutrient Offset Payments Rule).
The site shall be planned and designed encompassing land along Neville Creek, a tributary to University Lake
south of Chapel Hill in Orange County North Carolina. For the purposes of this Bank Parcel Development
Package (BPDP) the Site is divided using the following designations:
• Tract 1 — Main project area on the north side of Neville Creek and accessible from Old
Greensboro Highway.
• Tract 2 — Area south of Neville Creek and accessible from Stansbury Road.
Though the properties are adjacent, the division of the site is necessary based on land use, project crediting,
and for more clear referencing within this document.
The purpose of both rural tracts is to establish forest adjacent to surface water features to reduce nutrients
that flow into Neville Creek, University Lake, and ultimately, Jordan Lake. The project will have ancillary
benefits that include reducing sediment runoff, reducing nutrients to streams through agricultural runoff, and
thus, improving aquatic and terrestrial habitat. Any nutrient offset or riparian buffer mitigation generated
from this restoration would be available to offset impacts from development, both existing and proposed,
within the Upper New Hope Subwatershed of Jordan Lake, as verified by DWR staff onsite and in their letter
dated April 6, 2015 (Attachment F).

2.0 PROJECT SITE DESCRIPTION
2.1 Land Use
Attachment A- Figure 2 has a map of the Site. The Site is contained on two tracts: Attachment A- Figure 2
provides a 2013 aerial of the Site while Attachment J contains on the ground photos of the site. These two
properties are further described below:
1. Tract 1 —Part of a 112 acre farm that includes livestock pasture, woodlots, and hay production. The
proposed conservation easement is approximately 4.6 acres and is located on an area dedicated to hay
production, which is classified as an agricultural practice. Annual nitrogen application rates for the
property are approximately 100 lbs /ac. Portions of the riparian area currently have a narrow buffer
of trees (10 -15ft) immediately adjacent to the stream. The majority of the proposed reforestation is
in the 100 year floodplain for Neville Creek. Runoff from the Site flows directly to Neville Creek.
Approximately 4.4 acres of land are proposed for the generation of nutrient offset or buffer
mitigation credit on this property (Note: As planned, a 0.20 acre portion of the conservation
easement will extend beyond 200 ft. from the stream and not be eligible for nutrient or buffer
mitigation).
2. Tract 2 — Part of a 9 acre single - family residential property with the pervious areas maintained as a
fescue grassed lawn, which is not classified as an agriculture practice. The proposed conservation
easement is approximately 1.7 acres. Portions of the proposed easement area currently have a
narrow forested buffer of 10 -15 ft. An area at the lower end of the project site has grown over in
blackberry and honeysuckle and is planned to be cleared and reforested to help restore the native tree
buffer. Surface water leaves the site directly through drainage to Neville Creek.

2.2 Watershed Setting
Attachment A- Figure 3 provides a map of the Site in context with its watershed setting. Neville Farms is in
Jordan Lake's Upper New Hope subwatershed. In addition, the Site is upstream of University Lake, a
designated Water Supply Watershed. University Lake is used by the Orange County Water and Sewer
Authority to provide water to municipalities that include Chapel Hill and Carrboro. Table 2.2 provides
summary of watershed information on the Site.

2.2 Surface Hydrology and Watershed Area
The surface water from the Site drains directly to Neville Creek at Assessment Unit (AU) 16- 41- 2- 2 -1 -(1)
which subsequently flows to University Lake and then Jordan Lake. As shown in Table 2.3, this AU was not
rated in NC DWR's 2014 Water Quality Assessment (NC DWR 2014).
Table 2.3. Neville Creek use classification for the project stream at the Site Source: NC DWR 2014).

16- 41- 2- 2 -1 -(1) Not Rated
2.3 Surface Water Determination for the Site
Orange County is delegated authority by the NC Environmental Management Commission to conduct
determinations on whether drainage features in their jurisdiction are surface waters and subject to the buffer
rules of the State found in 15A NCAC 02B .0267 Protection of Existing Riparian Buffers. Orange County
Planning and Inspections assessed the Site and on February 9tb, 2015 provided their determination that the
surface water features on the site are subject to the Rule. Attachment B provides a copy of this
determination.
2.4 Floodplain Assessment
The majority of the Site is in the floodplain. The project, however, will not affect areas of the stream and no
actions associated with the project are expected to be in conflict with the County or State floodplain
management requirements. Orange County's floodplain administrator was notified of the project and
requested to review the proposed project activities and determine if additional actions are needed for project
approval.
Attachment C contains the Orange County Floodplain Manager's determination that the project "will not
require additional floodplain analysis as the reestablishment of vegetation is not deemed to create /impact
Neville Farms BPDP Watershed Investments NC
existing floodways." Further County staff issue "approval for the project from both a zoning and flood
permitting standpoint" (Orange County, 2015).
-'. Geology &Soils
The Site is located in the Carolina Slate Belt Level 3 Ecoregion. According to Griffin et. al (2002), this region
contains mineral rocks along with silty and silty clay soils. Also, low water yielding rock in the ecoregion lead
to streams drying up in the summer months.
Attachment A- Figure 4 provides a map of the soil at the Site. These soils data are summarized in Table
2.4. The predominant soils on the site are Congaree which are well drained loamy alluvium. These have a
seasonally high water table and are prone to flooding. Other soils on the site (Appling, Georgeville, and
Goldston) are deep, well drained, and have little organic matter. Ridges in the hay fields of Tract 1 contain
sporadic areas of shallow rock along the steeper slope faces. The shallow rock will not preclude the
establishment of forest that meets rule requirements for the mitigation area.

2.6 Cultural Constraints
Cultural resources include historic and archeological resources located in or near the project parcel. The
evaluation of cultural focused primarily on the presence of cultural resources as determined by the North
Carolina State Historic Preservation Office (SHPO) and through field observations. The SHPO GIS Web
Service database did not reveal any listed or potentially eligible historic or archeological resources in the
proposed project area (NC SHPO 2015). No architectural structures or archeological artifacts have been
observed or noted during surveys of the site. The State Historic Preservation Office (SHPO) has been
notified of the proposed project and confirmed that their database contains no record of important cultural
resources in the easement area. A copy of their review and response letter is provided in Attachment D.
2.8 Rare, Threatened and Endangered Species
Plants and animals with a federal classification of endangered (E) or threatened M are protected under
provisions of Sections 7 and 9 of the Endangered Species Act of 1973, as amended. The US Fish and Wildlife
Service ( USFWS) database for Orange County, NC (updated 12/27/2012) lists the following one endangered
species classified as Current and 2 as Historic ( USFWS 2012):
• Dwarf wedgemussel (Alasmidontaheterodon) - Current;
• Michaux's sumac (Rhusmichauxii) — Historic;
• Smooth coneflower (Echinacea laevigata) - Historic;
The USFWS database also lists the Bald eagle (Haliaeetus leucocephalus) for the County. This species is
protected under the Bald and Golden Eagle Protection Act (BGPA) and prohibits take of bald and golden
eagles. No protected species or potential habitat for protected species was observed during preliminary Site
evaluations.
In addition to the USFWS database, the NC Natural Heritage Program (NHP) was contacted to determine
whether previously cataloged occurrences of protected species were mapped within one mile of the project
site. A copy of the correspondence with the NHP is included in Attachment E. Results from NHP indicate
the following two species have were observed in the year 1940 within a mile of the project area.
• Pursh's Wild- petunia (Buellia purshiana) — A plant species with a status of Special Concern- Vulnerable
(SC -V) observed in 1940. Its habitat is woodlands, mostly over mafic or calcareous rocks (NHP
2014).
• Coppery Emerald (Somatochlarageogiana) — A dragonfly Somatochlorageorgiana lacked specific location
information so it's observation has low accuracy but it has been observed in Orange County. This
species prefers "small, sand, forest streams" as habitat (Paulson 2011).
Pursh's Wild- petunia's habitat is predominantly woodland's and on rocks. Existing woodlands and rocks will
not be areas subject to planting activities with this project. The dragonfly species Somatochlorageorgiana habitat
is forested streams. Most of the Site's riparian areas have a narrow mature tree buffer. Planting activities will
remain outside of that buffer with tree planting activities associated with this mitigation project expanding on
the tree cover favored as habitat for this species. Based on initial site investigation and species habitat
preferences, no impacts to state protected species are anticipated as a result of the proposed project.

Z.9 Existing/ Historic Vegetation
The majority of Tract 1is currently planted in fescue and rye grass for hay production. Tract 2 is a mostly
fescue lawn with a mix of other native and planted grasses. Most areas on both sides of Neville Creek have a
narrow (10 -15 ft) tree buffer adjacent to the stream that provides some buffer functions. This thin buffer
area has a mix of native trees (Gum, Red Cedar, Ironwood, Tulip Poplar, Pine) along with some invasive
shrubs (Chinese Privet, Autumn Olive). Historical imagery from 1993 confirms that this land use occurred
prior to the existence of buffer protection rules for the area (See Attachment A- Figure5).
Table 2.5 provides a summary of the dominant woody vegetation found in the streamside buffer area. Based
on feedback from the Division of Water Resources staff, those areas with existing tree cover will be
considered as Buffer Preservation for mitigation purposes.

3.0 PROJECT PLANTING PLAN
3.1 Riparian Restoration Activities
The riparian restoration will be conducted according to 15A NCAC 02B.0295. The restoration of plant
communities within the Site will provide stabilization and improve water quality within the parcel. The
protected buffer easement will be planted up to 200 feet from the top of the stream bank, with appropriate
native species observed in the surrounding forest and species known to occur in similar environmental
settings. Fencing will not be installed as neither tract is used for pasture and livestock will not have access to
the area adjacent to the established easement. The buffered channels will provide water quality and habitat
functions within the Nutrient Sensitive Waters of Jordan Lake.
Some areas of the easement may require maintenance to prevent the establishment of invasive and /or exotic
species. Pre - planting treatment will be used to help remove these species limit the need for these maintenance
activities.

Neville Farms BPDP Watershed Investments NC
3.2 Planting Plan
Revegetation of the Site will include planting bare root trees and controlling invasive species growth. To
achieve a minimum stem density of 260 stems /acre after 5 years, planting density will be at least 436
stems /acre on 10 foot x 10 foot spacing. Volunteer species at the Site may be considered by the Division to
count toward meeting these performance standards. The initial planting of bare root trees will occur in the
Fall/Winter of 2015/2016 when tree species are dormant. Recruitment of volunteer species in the floodplain
is anticipated due to forests that exist upstream and on the stream bank.
The Site consists predominantly of bottomlands which will be planted as Piedmont Alluvial Forest. When
planting, at least four (4) species from Table 3.1 will be selected for the site with no one species comprising
more than 50% of the total planted stems. Planted stock will be high quality seedlings approximately 24
inches in height. Seedlings will be hand - planted using KBC planting bars and will be pretreated with an endo/
ectomycorrhizal spore root treatment.

A narrow buffer of mature trees exists on the site along portions within Zones 1 and 2 of Tracts 1 and
2.Zones 1 and 2 are defined in 15A NCAC 02B.0267 and extend a maximum distance of 50 feet from the
stream. The preservation area was reviewed by the Division of Water Resources and determined eligible for
Buffer Preservation (see Attachment F). Preservation areas will be included in the conservation easement
and invasive species populations that threaten the integrity of the native hardwood community will be
controlled. There will be no planting in these areas.
3.4 Site Preparation and Invasive Species Control
Soil conditions in floodplain areas, which are predominant at the site, are not compacted and not in need of
disking to rip and loosen the soil. A focus of site preparation will be to treat and manage invasive species
listed in Table 2.6 in buffer preservation and restoration areas. Invasive species management of existing
woody invasive plants within the existing woodland buffer will take place during the first year. Larger shrubs
may be treated as a cut stump treatment while smaller vegetation is sprayed. Any applications will completed
by a NC licensed pesticide applicator.
In addition, within the planting areas of Tract 1 and Tract 2 herbaceous competition management will be
conducted as necessary during the first full growing season. Herbaceous competition management will
consist of mowing as well as targeted herbicide spraying of such species as blackberry, honeysuckle, and
Johnson grass.
3.5 Easement Boundaries
Easement boundaries will be identified in the field to ensure clear distinction between the Site and adjacent
properties. Boundaries may be identified by marker, bollard, post, tree- blazing, or other means as allowed by
7
Neville Farms BPDP Watershed Investments NC
site conditions and/ or conservation easement. Boundary markers disturbed, 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 with the status of the boundaries reported in annual monitoring reports.
4.0 PROJECT MONITORING AND PERFORMANCE STANDARDS
Pursuant to criteria found in the Temporary Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 and
Neville Farms Mitigation Banking Instrument (MBI), the measures of vegetative success for the Parcel will be
the survival of at least 260 planted trees per acre at the end of Year 5 based on monitoring of the site. Natural
recruits will not count towards annual achievement of performance standards; however they may be taken
into account during review by the NC DWR.
Invasive and noxious species will be monitored and controlled so that none become dominant or alter the
desired community structure of the site.
4.1 Project Monitoring Plan
Riparian buffer vegetation monitoring will be based on the CVS -EEP Protocol for Recording Vegetation
Level 2 Plot Sampling Only Version 4.2. Annual vegetation monitoring will occur each year during the fall
season with the first year occurring at least 5 months after initial planting. Six (6) vegetation monitoring plots
will be a minimum of 0.02 acres in size, and cover between 2% and 2.5% of the planted area. Data collected
will include: species, height, planting date (or volunteer), and grid location.
4.2 Adaptive Management Plan
In the event that the Site, or a specific component of the Site, fails to achieve the defined performance
standards, WINC will develop necessary adaptive management plans and /or implement appropriate remedial
actions for the Site in coordination with the NC DWR. Remedial actions will be designed to achieve the
performance standards specified previously, and will include identification of the causes of failure, remedial
design approach, work schedule, and monitoring criteria that will take into account physical and climatic
conditions.
+.3 Long Term Management Plan
WINO, acting as the Bank Sponsor, will establish a Conservation Easement, and will monitor the Site for a
minimum of five years, or until NC DWR approval has been given. Prior to the submission of the 4th year
monitoring report, the Site will be transferred to a responsible third party. The third party shall be responsible
for periodic inspection of the Site to ensure that restrictions required in the Conservation Easement or the
deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed
restrictions shall be negotiated prior to site transfer to the responsible party.
The Bank Sponsor will ensure that the Conservation Easement will allow for the implementation of the
monitoring phase, which will be developed during the design phase and conducted by the Bank Sponsor. The
Conservation Easement will allow for yearly monitoring and, if necessary, maintenance of the Site. These
activities will be conducted in accordance with the terms and conditions of the Neville Farms MBI.

Neville Farms BPDP Watershed Investments NC
5.0. FINANCIAL ASSURANCE
The Sponsor shall provide financial assurances in the form of a Performance Bond sufficient to assure
completion of all mitigation work, required reporting and monitoring, and any remedial work required. The
amount of this assurance is driven in part by the Site meeting requirements outlined by the Division in a
memo released on 4-2 -14 (See Attachment G). In the memo, the Division outlines criteria that allow for a
site to seek performance bond amounts commensurate with project costs. To qualify, sites must meet the
following criteria:
• Project is for riparian restoration by approved private mitigation bank;
• Proposed mitigation area is 10 acres or less in size;
• Project does not require fencing; and
• Project does not include stream and /or wetland mitigation.
The Neville Farms Bank Parcel meets the above criteria. As a result, performance bond amounts will be
based, in part, on project specific costs. Tables 5.1 and 5.2 detail the project costs related to construction
and monitoring of the site, respectively. Construction costs for the project are determined to be $40,300 while
monitoring costs are $39,000. Table 5.3 provides a list of the consultants and contractors who are planned to
work on the Bank.
To comply with DWR policy, a performance bond must be acquired to cover 100% of construction cost or
$50,000, whichever is greater. For monitoring, the bond must cover the monitoring costs or, at a minimum,
be in the amount of $25,000. Accordingly, bond amounts of $50,000 and $40,000 will be secured to comply
with the financial assurance requirements of the State for construction and monitoring, respectively.
Alternatively, in lieu of posting the Construction Bond, the Sponsor (WINC) may elect to construct the
project prior to the first credit release.
Financial assurances shall be payable at the direction of the NC DWR to his designee or to a standby trust.

As noted in the Neville Farms MBI, buffer credit determination is subject to the Temporary Buffer Rule 15A
NCAC 02B .0295(h). Figure 6 identifies the buffer zone areas. Buffer credit will be generated from both
Preservation and Mitigation activities. Table 6.1 provides a summary of the buffer credit calculation for each
zone and the totals for the Site. Details of the planting and restoration activities planned for the Site are
outlined in Section 3.0
In accordance with Rule 15A NCAC 02B .0295, the width of the buffer /nutrient credit generation area will
begin at the most landward limit of the top of bank or the rooted herbaceous vegetation and extend landward
to a maximum distance of 200 feet. Preservation areas meet the requirements described in .0925 (m)(2)(D) —
Preservation of Buffers on Subject Streams. Restoration areas meet the requirements of .0295(1) — Riparian
Restoration or Enhancement. Nutrient Offset credits sought are consistent with rules 15A NCAC 02B .0240
and .0273.
The Site will be constructed consistent with the Neville Farms NMI. Upon approval of this BPDP, a
conservation easement survey and plat will be recorded with the Orange County Register of Deeds office. A
final survey of the mitigation area will also be conducted after construction has been completed and will be
submitted to the Division for approval with the project's as -built report.

Tract 1 will be used to generate nutrient offset credits in conformance with the Neville Farms MBI. Table
6.2 provides a summary of the nutrient credit calculation for each zone buffer of Tract 1 and the totals for
the Site.
To comply with the requirements of 15A NCAC 02B .0273(2)(d)(i), nutrient credit sales will need to "account
for differences in instream nutrient losses between the location of the reduction need and excess loading
reduction in reaching the affected arm of Jordan Reservoir ". To accomplish this, delivery factors are applied
to reductions generated at Neville Farms to calculate the nutrient pounds delivered to Jordan Lake. Loading
reduction sales, therefore, will take into account nutrient deliveries to the lake. Attachment I provides the
Division's delivery factors that apply to the Site. Neville Farms falls into Zone 9 for nitrogen and Zone 8 for
phosphorus resulting in delivery factors of 89% and 79 %, respectively.
As indicated in the Site's MBI, credits generated from riparian buffer restoration activities can be converted
from buffer to nutrient offset with Division approval and from nutrient offset to buffer. However, when
converting from nutrient offsets to buffer, all applicable ratios and percentages of full credit will apply
according to 15A NCAC 02B.0295.
As indicated in the Neville Farms MBI, Tract 2 requires differing methods to develop available nutrient
credits than Tract 1. WINC used the Jordan -Falls Stormwater Accounting Tool QFSAT) to calculate nutrient
offsets for Tract 2. Based on the application of the JFSAT, the generated nutrient offset credits available for
Tract 2 are 1091.10 lbs N and 243.00lbs P. With application of the delivery factor 89% for nitrogen and 79%
for phosphorous, the delivered nutrient offset credits available for Tract 2 are 971.079 N lbs and 191.97 P lbs.
Attachment H provides a summary of the Division's approval of Tract 2's credit calculation along with a
summary of the methods used in the calculation.
For purposes of credit conversion from nutrient offset to buffer, the following ratios shall apply:
• Tract 1: 1 square ft. of buffer = 0.0498 lbs of nitrogen and 0.0033 lbs of phosphorus
• Tract 2: 1 square ft. of buffer = 0.0209 lbs of nitrogen and 0.0047 lbs of phosphorus
Neville Farms' Nutrient Offset and Riparian Buffer credits will not be credited within the same area (not
stacked). However, with DWR approval, WINC may transfer unsold credits generated from riparian
restoration activities between credit types to satisfy market demands. The Neville Farms Bank will service
impacts within the Upper New Hope Subwatershed of Jordan Lake.

Mike / Katie,
I had our Current Planning Division here at Orange County put together the attached "Site Assessment"
showing current environmental conditions on the southernmost property bordering the stream in
question. This is a standard document given to citizen's inquiring about parcels of land. Our system is
organized by PINS instead of physical addresses or latitudes / longitudes, but you should be able to
easily cross reference the supplied data. The stream in question is shown on both the USGS and Soil
Survey, hence portrayal on our GIS System. It also has associated floodway / floodplain with
approximate required Orange County stream buffers as shown.
With regards to the question of it being a jurisdictional stream subject to buffer rules ... Orange County is
delegated by DWR to conduct Surface Water Determinations and our protocol is as follows: a stream is
considered as jurisdictional if it shows up on the Orange County GIS System (a collection of both USGS
and Soil Survey Streams) and can only be removed by staff certified in Surface Water Identification after
a jurisdictional call of removal is made at the required cost for assessment ($200 for 1 -2
Determinations /Site ). Our aerial imagery clearly shows the section of Neville Creek in question as a
"water flowing" feature, so I saw no reason for a site visit at the expense of the client. This imagery can
be viewed at the following link:

Please advise if further verification is needed.

Hi Wesley — Would you be able to provide the documentation that Katie mentions? I think the
assessment you referenced would be good supporting evidence but I'll also need documentation from
you or someone else at the county who can make stream determinations that the stream section on

Hi Katie —
I contacted Wesley Poole from Orange County Soil and Water about the Neville Farm site I reference in
the email I'm forwarding. Due to the size of the stream he observed on aerial photography and its
presence on the 1:24,000 topographic map, Mr. Poole determined that the stream section in question
would be jurisdictional and subject to the buffer rule and that a field determination was not necessary.
What information would you like me to have to document his determination?

RE: ORANGE COUNTY FLOOD PERMIT DETERMINATION — proposed
establishment of conservation area and replanting of vegetation within identified
Special Flood Hazard Area (SFHA) Overlay District for 2 parcels of property
(PINS 9768 -11 -1753 and 9767 -29 -5479)
To Whom It May Concern:
Orange County is in receipt of a Floodplain Development Permit proposing the
reforesting of property within an identified floodplain. Specifically, the project will involve the
planting of native trees along Neville Creek to on the following parcels:
1. An approximately 112 acre parcel of property owned by Nettie Gambill, no
assigned physical address, identified utilizing Orange County Parcel Identification
Number (PIN) 9768 -11 -1753, and
2. An approximately 8.7 acre parcel of property owned by John and Janine McGee
with a physical street address of 2201 Stansbury Road further identified utilizing
Orange County Parcel Identification Number (PIN) 9767 -29 -5479.
The parcels identified herein are both zoned:
• Rural Buffer (RB),
• University Lake Protected Watershed Protection Overlay District, and
• Special Flood Hazard Area Overlay District (SFHA)
The SFHA district, as you are already aware, indicates there is identified floodplain on
the 2 properties, as denoted on Federal Insurance Rate Maps (FIRM) number 3701983100J
panel(s) 9768 and 9767 J respectively with an effective date of February 2, 2007 (hereafter `the
property').
C -1
The project is intended to reestablish protective vegetative cover along the
aforementioned waterway. According to the information supplied to staff the project will not
involve the excavation existing land, or the depositing of fill material, within the floodplain. The
submitted map does not indicate the presence of wetlands within the project area (hereafter `the
project').
As a result of the properties being located within the SFHA district, development projects
are required to demonstrate compliance with established flood regulations as embodied within
the Orange County Unified Development Ordinance (UDO). The County also has regulations
requiring the protection of the natural areas around water features (i.e. stream buffers)
regulations as detailed within Article 6 of the UDO.
Staff has been asked to review the proposal and determine compliance with applicable
County regulations. This project involves the review of several agencies, most notably the NC
Department of Environment and Natural Resources (DENR), in determining the viability of the
project. This letter only focuses on any local (i.e. Orange County) permit standards and does not
presume to identify requirements associated with any other permitting process.
Upon review of the proposal, staff would like to offer the following comments:
1. The request has been submitted in accordance with the provisions of Section 2.6.2
Floodplain Development Permit and Certificate Requirements — Plans and Application
Requirements of the UDO.
Per Section 6.13.6 Stream Buffers — Uses Allowable Within Stream Buffers of the UDO
`restoration of stream buffers' is allowed as a `matter of right' within identified stream
buffers.
3. In reviewing the submitted plan the project does not call for the depositing of fill material
within the identified floodplain or the floodway.
Grading activities will be limited to those portions of the project requiring the actual
disturbance of land area for the purpose of re- establishing native vegetation.
4. In reviewing the submitted site plan there does not appear to be any alteration of existing
grade or the `mass grading' of property to accommodate the project.
5. Per Section 6.6.1 (14) of the UDO disturbance projects within identified floodplains
shall: `minimize flood damage consistent with these and other applicable County
regulations'.
Based on the submitted documentation it would appear the project will comply with
applicable development guidelines associated with the SFHA Overlay District and is
consistent with FEMA regulations governing land disturbance activities within identified
floodplain areas.
Based on the submitted documentation, and in accordance with Section 2.6.2 of the
UDO, staff can issue approval for the project, from both a zoning and flood permitting
standpoint. The project will not require additional floodplain analysis as the reestablishment of
C -2
vegetation is not deemed to create /impact existing floodways. The project, in fact, will help to
bring the property back into compliance with applicable stream buffer regulations and further
stabilize the banks of Neville Creek.
Please note land disturbing activities shall be permitted to commence once all other
required permitting processes have been adhered to, including any applicable Erosion Control
permits issued by Orange County and any required State/Federal permits, with copies of said
authorizations being provided to the County for our records.
The Orange County Planning department looks forward to continue working with you on
this project. Please contact staff at (919) 245 -2575 for additional assistance.

RE: Neville Farms Nutrient and Buffer Mitigation Bank Site, Orange County, North Carolina
Dear Mr. Herrmann:
Thank you for the opportunity to provide information from the North Carolina Natural Heritage Program
(NCNHP) database for the proposed project referenced above. The NCNHP database shows a record for
a rare species — Pursh's Wild- petunia — that may occur within or nearby the proposed project area, and
also a property owned by Orange County and considered to be Orange County open space immediately
east and adjacent to the project area along Neville's Creek.
Within one mile of the project area, the NCNHP database shows element occurrence records for the
following rare species:
*For status and accuracy definitions, please see the Rare Species Status Definitions and Element Occurrences documents at
https: / /ncnhde. natureserve.Org/content/help.
The occurrence record for Pursh's Wild- petunia is from a dry road bank in the vicinity of Neville's Creek
near University Lake, and is mapped in the NCNHP database as potentially occurring within your project
area. Although the record for Pursh's Wild- petunia is considered to be historical, the last observation
was made in 1940 by Al Radford and according to the NCNHP database the area has not been surveyed
since the original observation. The occurrence record for Coppery Emerald has very low accuracy due to
the lack of site- specific locational information associated with the record, but this species has been
documented in Orange County.
In addition, the NCNHP database shows several conservation /managed areas within one mile of the
project area, including the property owned by Orange County adjacent to the eastern portion of the
project area as noted above, as well as other Orange County open space properties upstream and
downstream from the project, a conservation easement managed by the Triangle Land Conservancy ca.
0.45 miles east of the project, and properties under conservation easement managed by Earthmark
North Carolina, LLC, located ca. 0.9 miles northwest of the project area.

Re: Site Viability for Buffer Mitigation & Nutrient Offset — Neville Creek
Near 1501 Old Greensboro Rd, Chapel Hill, NC
Orange County
Dear Mike,
Donald R. van der Vaart
Secretary
On February 13, 2015, Katie Merritt, with the Division of Water Resources (DWR), received a request from
Watershed Investments NC, LLC (WI) for a site visit near the above - referenced site to determine the
potential for nutrient offset and Jordan riparian buffer mitigation. On March 24, 2015, Ms. Merritt
performed a site assessment of two properties near the subject site, which are more accurately described
in the attached aerial map. If approved, mitigating these properties could provide riparian buffer credits
and /or nutrient offset credits within the Upper New Hope Watershed of the Cape Fear River Basin.
Ms. Merritt's evaluation of the two properties' for buffer and nutrient offset mitigation is shown below:
Gambill Property
• Stream onsite is Neville Creek and was determined to be at least Intermittent by the Town of
Chapel Hill (email from Wesley Poole with Orange County on February 9, 2015).
• The narrow forest fringe along Neville Creek was described to be mature with a closed canopy the
entire length of Zone 1 of the proposed mitigation area. Therefore, Zone 1 is viable for buffer
preservation only and suitable for buffer mitigation credit only.
• The existing land use condition within Zone 2 of the Jordan buffer (21 -50') was determined to be
active hay crop cultivation. Therefore, Zone 2 is viable for buffer restoration and suitable for either
buffer mitigation credit or nutrient offset credit.
• The existing land use of the riparian area located outside of the Jordan buffer (51 -200') was
determined to be active hay crop cultivation. Therefore, this area is viable for riparian restoration
and suitable for either buffer mitigation credit or nutrient offset credit.
McGee Property
• Stream onsite is Neville Creek and was determined to be at least Intermittent by the Town of
Chapel Hill (email from Wesley Poole with Orange County on February 9, 2015).

The existing land use condition within Zone 1 and Zone 2 of the Jordan buffer (0 -50') was
determined to be a mixture of mature hardwood trees with a disturbed understory dominated by
invasives. The area within the Jordan buffer was determined to be viable for buffer restoration and
suitable for buffer mitigation credit only. Site preparation will be needed to manually remove the
invasives. Additionally, all of the erosional gullies and holes must be filled and stabilized to
promote diffuse flow of stormwater runoff within the buffer. All trees must be surveyed out of the
total square footage of the proposed mitigation area.
The existing land use condition outside of the Jordan buffer (51 -200') was determined to be a
maintained lawn and not in agriculture. This area is viable for riparian restoration and suitable for
only buffer mitigation.
A map showing the project site is provided and signed by Ms. Merritt on April 6, 2015. For any areas
depicted as not being viable for nutrient offset credit above, WI could propose a different measure, 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 NCAC 02B.0240.
Please contact Katie Merritt at (919)- 807 -6371 if you have any questions regarding this correspondence.

SUBJECT: Notification of potential changes to performance bond requirements for construction
and monitoring costs of nutrient offset and riparian buffer mitigation banks in NC
On February 19, 2014, Assistant Secretary of the North Carolina (NC) Department of Environment & Natural
Resources, Mitch Gillespie, responded to a concerned citizen's letter requesting staff within the Division of Water
Resources (DWR) re- evaluate the minimum requirements of performance bonds for nutrient offset and riparian
buffer mitigation banks in NC. Currently, the requirements area minimum of $150,000 and $100,000 for
construction and monitoring costs respectively. Staff within the 401 & Buffer Permitting Unit of the DWR,
conducted a thorough review of information received from mitigation providers and consultants and determined
that performance bonds less than the current minimum bond requirements may be accepted on a case by case
basis. Restrictions to the changes in bonding amounts are as follows:
• Applicable for riparian restoration projects conducted by approved private mitigation banks only;
• Applicable for projects 10 acres or less in size as shown on a survey;
• Applicable for projects that do not include fencing as part of the approval for mitigation;
• Not applicable for projects that include stream and /or wetland mitigation; and
• No bond shall be less than $50,000 and $25,000 for construction and monitoring costs respectively.
In accordance with the statement provided in Mr. Gillespie's response letter, the following applies:
• "Operational procedures that are not in direct compliance with existing Umbrella Mitigation Banking
Instruments (UMBI) will need to be approved prior to implementation ".
Therefore, mitigation bank sponsors who would like to modify the performance bond requirements on
buffer /nutrient offset riparian restoration projects may submit a modification of their existing UMBI for review
and approval by the Director of the Division of Water Resources (DWR), prior to implementation.
Please contact Katie Merritt at 919- 807 -6371 or katie.m err itt a.ncdenr.gov for UMBI modification requests or
questions regarding this correspondence.

Subject: Nutrient Offset Credit Caaculation Materials for Neville Farms —Tract 2
Mr. Davis
Attached for your review is the nutrient offset credit calculation and supporting materials for the
Tract 2 (McGee Site) of the Neville Farms Riparian Buffer and Nutrient Offset Mitigation Bank.
The following attachments are included in this submission:
A. Summary of Project and Nutrient Offset Calculation
B. Copy of Jordan Falls Stormwater Tool Data Sheets
C. Map of Tract 2 Portion the Neville Farms Nutrient Offset and Buffer Mitigation Bank
E) 401 °- Buffer 44nit l4etermination 17etter Removed in the Attachment as it is duplicated in Attachment F.
Would you please review these materials and respond as to whether you agree with the attached
offset credit calculation? The awarding of that credit will also be determined by whether the
project is developed in accordance with its Bank Parcel Development Package (BPDP) and if it
meets the regulatory requirements established in the project's mitigation banking instrument.
These are currently being developed in consult with the Division of Water Resource's 401 &
Buffer Permitting Unit.
Also, pursuant to 15A NCAC 02B .0273(2)(d)(i), the project will need to "account for differences
in instream nutrient losses between the location of the reduction need and excess loading
reduction in reaching the affected arm of Jordan Reservoir ". In past communications, you've
indicated that the Division is currently preparing to release delivery factors that will be applicable
to this project. When those become available, will you please forward them so that they can be
included in both the project's mitigation banking instrument and BPDP?
Thank you for your help in the review for offset crediting of this site. I understand that it
presented a departure from the traditional crediting sought for sites and, consequently, required
additional review and consideration. I appreciate the timely manner with witch you have
conducted your review.
Sincerely,

ATTACHMENT A. Tract 2 of Neville Farms Nutrient Offset Calculation Summary
Project Overview
Tract 2 is part of a larger restoration project identified as Neville Farms in the Bank Parcel Development
Plan that is currently being developed. Located adjacent to Neville Creek, a perennial stream in Orange
County, Tract 2 is on an 8.8 acre property owned by John McGee. The watershed draining through the
project site encompasses 31.6 acres. The proposed Tract 2 conservation easement is approximately 1.7
acres with 1.20 acres anticipated for reforestation. The remaining 0.5 acres, a narrow, mature buffer
ranging between 10 and 20 feet exists in portions of the easement area, will be considered as buffer
preservation with no proposed nutrient reduction benefit. Attachment C provides a map of the Site
including the land draining to it.
For areas of the conservation easement lacking a forested buffer or with forests less than 50 feet,
residential lawn will be replaced with native trees to create a buffer with widths varying between 50 and
150 feet. In accordance with current DWR policy, success criteria on the project will be based on a
minimum planted stem density survival of 260 stems /acre after 5 years.
Currently, the majority of Tract 2 consists of residential lawn. While it is eligible for buffer credit, staff
from the 401 and Buffer Unit directed me to work with the Planning Section to develop the nutrient
offset crediting because the site falls outside of the typical practice for generating nutrient offset credit
(i.e., riparian reforestation of agricultural land). Attachment D contains a copy of the letter summarizing
their determination.
Nutrient Reduction Calculation Summary
The calculated nutrient credit available for the site is 1091.10 N Ibs and 243.00 P lbs. This is based on an
annual nutrient offset crediting for the site of 36.37 N pound (Ibs) /year and 8.10 Ibs /year multiplied by
30 years. The method used to quantify nutrient offset credits has been developed through coordination
and communication with the NC DWR Planning Unit staff. The agreed on approach involves the use of
site - specific factors and the Jordan -Falls Stormwater Accounting Tool (JFSAT) Version 3.0. Supporting
printouts from the tool are included in Attachment B. A summary of the nutrient offset calculation is
included below.
Table A -1 provides a summary of the estimated reduction from the JFSAT. The JFSAT accounts for both
land conversion for nutrient removal from upland sources. The upland area is 29.93 acres. This area
includes The Orchard, a development under construction that contains a mix of residential and forest
land use with 2 ac residential lots being the predominant parcel type. Parameters used to run the tool
along with its output are contained in Attachment B.
