EXECUTIVE SUMMARY
Watershed Investments NC (Sponsor) is pleased to provide the NC Division of Water Resources (DWR) this
Year 1 (2017) Annual Monitoring Report for the Neville Farms Bank Parcel (Site). 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) and effective on January 291h, 2016.
The 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 is located approximately 3 miles southwest of Chapel Hill, NC and one mile upstream of University
Lake. Surface water drainage features at the Site feed into the Upper New Hope subwatershed of Jordan
Lake. The Site is located in the Cape Fear River Basin 14 -digit United States Geological Survey (USGS)
Cataloging Unit 03030002060070 of the South Atlantic/Gulf Region (North Carolina Division of Water
Quality [NCDWQ] Sub -basin Number 03-06-06).
Project restoration activities and planting were completed in November -December 2016. Completed project
activities, reporting history, completion dates, project contacts, and project attributes are summarized in
Tables 1-4 (Appendix A).
The site encompasses 6.15 acres of land along Neville Creek, which is a tributary to University Lake south of
Chapel Hill in Orange County North Carolina. Site activities consisted of approximately 5.04 acres of
riparian restoration and approximately 0.94 acres of riparian preservation. An additional 0.17 acres of Tract 1
is included in the project easement area but is outside the rule -defined riparian buffer zone and, consequently,
not included for either riparian buffer mitigation or nutrient offset credit generation.
The Site is comprised of two separate tracts owned by two different land owners and will be mitigated in two
phases. Phase 1 is comprised of Tract I and Phase 2 is comprised of Tract 2. Each phase/tract will have its
own credit release schedule for milestones met in accordance with the Neville Farms Mitigation Banking
Instrument (MBI). Though the tracts are adjacent, the division of the Site was necessary based on land use,
land planning, and project crediting. Moving forward; however, project activities for both Tracts should
proceed on the same schedule. Tract information is as follows.

Orange County is the 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 provided their determination on February 9th, 2015 that the
surface water features on the Site are subject to the Rule (Appendix C).
The project has restored and preserved 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
Bank Parcel may 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 a letter dated April 6, 2015 (Appendix
E).
At the request of NC DWR, one (1) additional permanent vegetation plot was installed in the Zone C
Restoration area of Tract 1 during year 1 annual monitoring for a total of five (5) permanent vegetation plots
in Tract 1 and two (2) permanent vegetation plots in Tract 2. During Year 1 (2017), mowing occurred to
reduce herbaceous competition of planted trees. Year 1 (2017) data was collected on October 11, 2017 by
Axiom Environmental and derived an average density of 532 planted stems per acre (excluding Evestakes). In
addition, all 7 vegetation plots were above success criteria of 260 planted stems per acre. No problem areas
were observed in Year 1 (2017).

1.0 PROJECT MONITORING AND PERFORMANCE STANDARDS
1.1 Project Monitoring Plan
Riparian vegetation monitoring for Phase 1 and Phase 2 will be based on the CVS Level 1-2 Protocol for
Recording Vegetation, Version 4.2 (Lee et al. 2008). Annual vegetation monitoring will occur each year during the
fall season with the first year for each Phase occurring at least 5 months after initial planting of the Tract/s.
Vegetation monitoring plots measure 0.0247 acre in size and cover 2% of the planted area. Accordingly, four
(4) permanent vegetative plots will be used to monitor Tract 1 and two (2) permanent vegetative plots will be
used to monitor Tract 2. At the request of NC DWR, one (1) additional permanent vegetation plot was
installed in the Zone C Restoration area of Tract 1 during year 1 annual monitoring for a total of five (5)
permanent vegetation plots in Tract 1 and two (2) permanent vegetation plots in Tract 2 (Figure 2, Appendix
A).
A reference photo will be taken from the southwestern corner of each plot. All planted stems in the plots
will be marked with flagging tape and recorded. Data collected will include species, height, planting type
(planted stem or volunteer), and grid location. Year 1 (2017) data was collected on October 11, 2017 by
Axiom Environmental and derived an average density of 532 planted stems per acre (excluding livestakes)
(Table 7, Appendix B).
The Sponsor shall submit to DWR an annual monitoring report for each phase, no later than December 31 of
each year for five consecutive years. Reports will document the success of the vegetation and any
maintenance, supplemental planting, or encroachment within the easement areas. As planting and the
monitoring for both Phase 1 and 2 occurred on the same schedule, WINC intends to submit one Monitoring
Report each year for at least 5 years to document the above requirements for both phases. All Monitoring
Reports shall reflect the Phase for which it is being submitted. Monitoring bonds shall be renewed with
confirmation of renewal provided to DWR with each annual monitoring report for each phase. DWR
reserves the right to alter the credit release schedule if monitoring reports are submitted without proof of
bond renewals.
Invasive and noxious species will be monitored and controlled so that none become dominant or alter the
desired community structure of the site.
In addition, easement boundaries will be checked annually with the status reported in annual monitoring
reports.
1.2 Success Criteria
Pursuant to criteria found in the Temporary Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295 and
Neville Farms MBI, vegetative success for the Site will require the survival of at least 260 planted trees per
acre at the end of Year 5 based on monitoring data compiled for the site and site visits by the DWR. Natural
recruits will not count towards annual achievement of performance standards; however, they may be taken
into account during review by the NC DWR. Recruitment of volunteer species in the floodplain is
anticipated due to adjacent forests that exist upstream and on the stream bank.

2.0 MITIGATION POTENTIAL
As noted in the Neville Farms MBI, buffer credit determination is subject to the Temporary Buffer Rule 15A
NCAC 02B .0295(h) and (i). Figure 3 (Appendix A) identifies the riparian areas and credit types for Phase 1
and Phase 2.
In accordance with Rule 15A NCAC 02B .0295, the width of the buffer/nutrient credit generation area
begins at the most landward limit of the top of bank or the rooted herbaceous vegetation and extends
landward to a maximum distance of 200 feet. Nutrient offsets are not being generated within the areas
described as Preservation. Preservation areas meet the requirements described in .0295 (m) (2) (D) —
Preservation of Buffers on Subject Streams. Restoration areas meet the requirements of .0295(1) — Riparian
Restoration or Enhancement. Nutrient Offset credits are consistent with rules 15A NCAC 02B .024.
The following is a summary of the Jordan Lake riparian buffer credits and nutrient offset credit calculations
for Phase 1 and Phase 2 of the Site. Detailed credit calculations are included in Tables 1A -1D (Appendix A).
Phase 1 Tract 1)
0 0.40 acres Riparian Buffer Preservation = 1742.4 square feet of credit
• 3.74 acres Nutrient Offset = 7220.59 lbs -N delivered and 424.90 lbs -P delivered)
Phase 2 Tract 2)
0 1.30 acres Riparian Buffer Restoration = 55,321.2 square feet (ft2) of credit
0 0.54 acres Riparian Buffer Preservation = 2330.50 square feet (ft2) of credit
As indicated in the Site's MBI, credits generated from riparian buffer restoration activities can be converted
and transferred from buffer credits to nutrient offset credits with Division approval and from nutrient offset
credits to buffer credits. However, when converting from nutrient offsets to buffer, all applicable ratios and
percentages of full credit will apply according to 15A NCAC 02B .0295.
Neville Farms' Nutrient Offset and Riparian Buffer credits will not be debited within the same area (not
stacked). The Neville Farms Bank will service impacts within the Upper New Hope Subwatershed of Jordan
Lake.
3.0 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 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.

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:
http://server2.co.orange.nc.us/OrangeNCGIS/default.aspx
Please advise if further verification is needed.
Thanks,

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

Neville Creek is subject to the buffer rules. The lat/long for the site that I've been using is 35.891902 N, -

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: Site Viability for Buffer Mitigation & Nutrient Offset — Neville Creek
Near 1501 Ofd 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 (W1) 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 befow:
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 crap cultivation. Therefore, this area is viable for riparian restoration
and suitabte for either buffer mitigation credit or nutrient offset credit.

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.

Rich -
Attached for the Nonpoint Source Branch's review are two documents related to the Neville Farms Buffer
Mitigation and Nutrient Offset Bank. Changes that occurred during bank construction have resulted in minor
adjustments to the conservation easement area of Phase 2. At the Branch's direction, the nutrient offset credit
calculation for Phase 2 was developed using the Jordan -Falls Stormwater tool Version 3.0. Once completed, this
summary along with your Branch's review and approval, will be needed in the final documentation of the "as -built"
plan.
Would the NPS Branch please review the attached materials and let me know if they adequately estimate the
nutrient reduction benefit of Phase 2 of the project?
I can be reached at the contact info below if you'd like to discuss this further.

Mr. Gannon:
Submitted for your review are materials documenting the revised credit calculation for Phase 2
(formerly referred to as Tract 2) of the Neville Farms Buffer Mitigation and Nutrient Offset
Bank. Changes that occurred during project construction have resulted in minor adjustments to
the conservation easement area of Phase 2 where the nutrient offset credit calculation was
developed using the Jordan -Falls Stormwater tool Version 3.0. Once completed, this summary
along with acknowledgement of your Branch's approval, will be needed in the final
documentation of the "as -built" plan.
The following attachments are included in this submission:
A. Summary of project, changes in the As -built to Phase 2, and revised nutrient offset
calculation
B. Copy of As -Built Jordan Falls Stormwater Tool Data Sheets
C. Map of Tract 2 Portion the Neville Farms Buffer Mitigation and Nutrient Offset Bank
D. Copy of the nutrient offset calculation documents approved by Planning Branch for the
BPDP
The awarding of credit will also be based on 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 associated with permit #2015-0636.
Thank you for your help in the review for offset crediting of this project.

Neville Farms Buffer Mitigation and Nutrient Offset Bank ("Neville Farms") is located south of Chapel Hill
in Orange County and consists of two Phases. Neville Farms' Mitigation Banking Instrument (MBI) was
signed between Watershed Investments NC, LLC (WINC) and the NC Division of Water Resources (DWR)
and effective on January 29th, 2016. The purpose of this project is to generate Jordan Lake riparian
buffer restoration and preservation mitigation credits as well as nutrient offset credit for use in the
Upper New Hope Subwatershed of Jordan Lake. Phase 2 restoration activities completed include the
control of invasive plants and the planting of native hardwood species on land formerly managed fescue
lawn.
Phase 2 of Neville Farms is located on an approximately 9 acre residential property. During the
construction of Phase 2, adjustments were made to the area included in the conservation easement that
differs from that planned easement reviewed by the DWR for the Bank Parcel Development Plan (BPDP).
Differences between the BPDP and as -built easement boundary are for the following reasons:
• The planned easement area was drawn remotely using GIS and tax parcel data. Parcel data,
however, did not reflect the surveyed location of the property boundary. Use of the surveyed
boundary resulted in conservation easement boundary changes (effect: increased area).
• Field identification and survey of the top -of -bank used to mark the easement boundary edge as
opposed to GIS identification (effect: refinement of top -of -bank with little overall area change).
• The property owner sought to exclude a corner of the planned easement to maintain its historic
recreational usage and playhouse structure (effect: decreased area).
As part of the BPDP, the Division directed WINC to use Version 3.0 of the Jordan -Falls Stormwater Tool
to estimate nutrient reductions from Phase 2 of the project. For consistency with this approach, the
same tool and version are used to estimate nutrient reductions based on as -built conditions.
Attachment B contains a copy of the Jordan -Falls tool worksheets reflecting as -built conditions while
Attachment D contains the original documentation that was reviewed and approved by the Non -point
source branch for the BPDP. It describes the project, restoration activities, and nutrient offset
calculations.
A map of the site and contributing drainage area is included in Attachment C. The watershed draining to
Phase 2 continues to experience development. In particular, The Orchard, a community of mostly two
acre lots continues to build and sell lots in what was formerly wooded land. Two acre lots are the
drainage area development type in the used in the parameterization of the stormwater tool
Table A-1 summarize the calculation of nutrient reductions as a result of the project based on as -built
conditions. A summary of the differences between the BPDP and as -built easement, watershed area,
and the nutrient reduction calculations is provided in Table A-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
D. 401 & Buffer Unit Determination Letter Removed in the Attachment
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. 1 appreciate the timely manner with witch you have
conducted your review.
Sincerely,

BPDP 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 lbs and 243.00 P lbs. This is based on an
annual nutrient offset crediting for the site of 36.37 N pound (lbs)/year and 8.10 lbs/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.
