Raleigh Farm Phase A— Nutrient Offset and Buffer Mitigation Bank Parcel
Wake County, NC— Neuse River Basin
1.0 Introduction
The Raleigh Farm Phase A Nutrient Offset and Buffer Mitigation Bank Parcel ("Parcel" or "Site") is
proposed under the terms and conditions of the Raleigh Farm Riparian Buffer and Nutrient Offset
Umbrella Mitigation Banking Instrument, made and entered into on , 20J by Restoration
Systems, LLC (RS), acting as Bank Sponsor (Sponsor), and the North Carolina Department of Environmental
Quality (NCDEQ), Division of Water Resources (DWR). The Parcel shall be planned and designed according
to the MBI, the Consolidated Buffer Mitigation Rule 15A NCAC 02B .0295, which became effective on
November 1, 2015, and the Nutrient Offset Credit Trading Rule 15A NCAC 02B .0703.
Located in Wake County, the Parcel encompasses 77.07 acres of agricultural land and forests. The primary
purpose of the Parcel is to provide Riparian Buffer Credit (RBC) and Nutrient Offset Credits (NOC) for
stormwater and wastewater permitting requirements within the United States Geological Survey (USGS)
Cataloging Unit 03020201 — RBC and NOC are available for offsets within the Cataloging Unit, excluding
the Falls Lake Watershed (Figure 1, Appendix A). The Site will restore 45.027 acres and preserve 22.856
acres of riparian area, measured perpendicularly 200 feet off the top of bank, from eight (8) unnamed
tributaries and one (1) in -line pond (Site Features)(Figure 2-5, Appendix A). An additional 9.187 acres will
be permanently protected within the conservation easement but will not generate credit. The 9.187 acres
consist of areas beyond 200-feet from Site Features, the footprint of Site Features, and non -credited
access/maintenance areas within the conservation easement.
The Site is situated on two tracts of land (Project Parcels), owned by the City of Raleigh (City). Project
Parcels are part of the City's Neuse River Resource Recovery Facility (NRRRF) and managed by the City of
Raleigh Public Utilities Department, also known as Raleigh Water.
Site features drain directly to Beddingfield Creek, a direct tributary to the Neuse River. Proposed Parcel
easement tracts will provide permanent protection to restored and preserved riparian buffers -- Table 1
details the Site's Easement Areas, with individual and total acreages.

The City began residual biosolid application on portions of the Project Parcels in 1980 and currently has
1,439 acres permitted for land application of biosolids on the larger farm. Land application of biosolids
has occurred on the parcels since acquired by the City except for the 10-year moratorium between 2003
and 2013. The Site, and proposed easement areas, are located away from fixed infrastructure associated
Raleigh Farm — Phase A Bank Parcel Development Plan (2019-1692 V4) Page 1 of 17
Neuse River Basin 8-Digit HUC: 03020201
with the application of biosolids (i.e., application piping and wellheads). In addition to biosolid
applications, the property is managed for hay and row crop production. A review of aerial photography
indicates agricultural areas of the property were converted from forest to agricultural before 1993, with
no significant changes to land use since.
Phase A will have its own credit release schedule for milestones met in accordance with the Raleigh Farm
Umbrella Mitigation Banking Instrument for Nutrient Offset and Riparian Buffer Credits (UMBE).
DWR representatives conducted onsite determinations for the applicability and suitability of Site Features
on June 2-3, 2020. Respectively, a Stream Determination and Site Viability letter were provided by DWR
an August 17, 2020, and September 24, 2020 — both letters are provided in Appendix B.
RS will secure a conservation easement to preserve the Site in perpetuity, restricting any development
that would impair or interfere with the Site's conservation values. City allowance of a conservation
easement is further described in Section 3.4 (Parcel Protection & Easement Boundaries) of this document.
Per the referenced Umbrella Mitigation Banking Instrument (UMBI) above, RS will arrange the transfer of
the conservation easement and its interests in perpetuity to a qualified holder under NC. General Statute
("GS") 121-34 et seq. and 170(h) of the Internal Revenue Code before the approval of the As -Built Report
by DWR. The holder shall be a land trust or stewardship program accredited by the Land Trust
Accreditation Commission and/or approved by DWR. A land trust must be certified under 501(c) (3) of the
Internal Revenue Code and must have the qualifications outlined in GS 105-130.24 and GS 105-151.12.

1.4 Parcel Overview
The Site's footprint totals 77.07 acres over two tracts of land. Current land use is a mixture of managed
fields for biosolid applications from the City`s NRRRF, row crop agriculture, and unmanaged hardwood
forests (Figure 2, Appendix A). The Site will provide riparian area restoration and preservation along 14
Project Features that drain directly to Bedingfield Creek, a direct tributary to the Neuse River.
Site Features are devoid of woody vegetation outside of forested areas due to historic and active
agricultural practices. Managed features are maintained (mowed/brush hogged) to keep woody
vegetation from establishing.
DWR representative conducted onsite stream determinations and site viability assessments for mitigation
potential on June 2-3, 2020. A summary of Parcel Features by classification is provided in Tables 3 and
graphically depicted in Figures 2-5 of Appendix A.

1.5 Historic Land Use
City of Raleigh's Neuse River Resource Recovery Facility (NRRRF)
The City began biosolid residuals application in 1980 and currently has 1,439 acres permitted for land
application. Land application of biosolids has occurred on Site since the City's acquisition of Project Parcels
except for a 10-year moratorium between 2003 and 2013. Several areas in the Site's proposed footprint
are subject to biosolids application. Specific field boundaries and active biosolid application areas are
further detailed in Figures 6 and 7 of Appendix A. The property is currently managed for hay and row crop
production.
Table 4 details a review of the City's Parcels with aerial photography beginning in 1969.

2.0 Project Area - Current Conditions
2.1 Physiography
The Site encapsulates heavily modified headwater stream systems within the Middle Atlantic Coastal
Plain. Specifically, Ecoregion IV--45f Northern Outer Piedmont, located within the eastern portion of the
Piedmont, to the Coastal Plain Fall Line, in northern North Carolina (the transition between North
Carolina's Piedmont and Coastal Plain). This ecoregion consists of dissected irregular plains, rounded hills
and ridges, and low to moderate gradient streams with mostly cobble, gravel, and sandy substrates
(Griffith et al. 2002).
The watershed is dominated by agricultural land, fringe forests, and impervious surfaces associated with
single-family homes and roads. Surrounding area land use is primarily row -crop agriculture, with some
low -density residential housing, cattle pasture, and forested lands.
2.2 Soils
A detailed soil report for the Site was produced using the Natural Resource Conservation Service's (MRCS)
Web Soil Survey (USDA 2019)(Appendix C). Based on the custom report, the Bank Parcel contains the soil
series outlined in Table 5.

2.3 Existing Vegetative Communities
Of the Site's 77.07-acre footprint, 46.51 acres are in managed agricultural fields or biosolid application
pasture. Typical crops grown include corn and soybeans, though individual fields are often subject to other
crops like sunflowers. Pasture areas are comprised predominantly of Bermuda and fescue (Festuca sp.)
gasses. Pasture fields are cut/managed throughout the year. In general, Site Features are subject to
agricultural impacts in the upper half of each individual watershed. As the Features migrate downstream,
they typically enter disturbed fringe forests, which expand as Site Features move down valley.
Site Features drain to Beddingfield Creek before entering the Neuse River, 1.5 miles downstream. The
southern extent of the Site abuts the Clem mons Educational State Forest and other lands managed by the
Raleigh Farm - Phase A Bank Parcel Development Plan (2019-1692 V4) Page 6 of 17
Neuse River Basin 8-Digit HUC: 03020201
State of North Carolina (NHP Report Appendix F). Existing hardwood forests of these managed properties
are consistent with Piedmont mesic forests, which occur on moist portions of upland habitat, steep north -
facing slopes, lower slopes, along ravines, high sections of outer floodplains, and stream bottoms. The
most common subtypes in the Piedmont are Mesic Mixed Hardwood Forest and Basic Mesic Forest
(Schafale, M.P. and A.S. Weakley. 2012).
Given the Parcels physiography, R5 has determined a mix of Mesic Mixed Hardwood Forest (Piedmont
Subtype), and Piedmont Bottomland Forest is the most appropriate reference forest (Schafale, M.P. and
A.S. Weakley. 2012). Table 6 outlines the species included in these reference forest ecosystems.

2.4 Parcel Design and Implementation Constraints
The presence of conditions or characteristics that have the potential to hinder restoration activities on
the Site were evaluated. The evaluation focused primarily on the presence of hazardous materials,
utilities, restrictive easements, rare/threatened/endangered species or critical habitats, the potential for
hydrologic trespass, and existing NRRRF infrastructure. Existing information regarding Site constraints was
acquired and reviewed, including an Environmental Records Report developed by Environmental Data
Resources Inc., which located no evidence of environmental risk associated with the Parcels (Appendix D).
A North Carolina Natural Heritage Program Report was conducted and concluded three known historic
locations within the area, but all are located outside the proposed footprint (Appendix F).
Site conditions (existing or future) that have the potential to restrict the restoration, implementation and
long-term protection of the Site were documented digitally and during the field investigation. A summary
of findings and design avoidance is detailed in Table 7 on the following page.

The Site's proposed easements are located outside of the utility easement.
Duke Energy — Piedmont
Natural Gas (PNG) Line 142
RS received a City of Raleigh -approved easement boundary from Duke Energy regarding
the future natural gas line — PNG Line 142. The Site's proposed easements are located
outside of the utility easement. Construction of the PNG Line 142 will not affect the project
nor its protected resources.
Dominion Energy's T-030 Gas
Pipeline Extension Project
(Franklin and Wake County)
DWR Project ID No. 2019-0828
V2
Beginning construction in 2020 with an expected completion date in 2021, Dominion
Energy's T-030 Gas Pipeline Extension Project will maintain a 50-foot utility easement over
Project Parcels associated with Phases A. The new easement abuts and runs parallel along
Duke Power's 200-foot overhead transmission line easement. The Sponsor accessed the
digital file of the permanent and temporary construction easements for the T-030 Gas
Pipeline. Site design avoids all temporary and permanent easements associated with the T-
030 Gas Pipeline. The Site's proposed easements are located outside the T-030 Gas
Pipeline easement (permanent and temporary).
NRRRF biosolid application &
ground water monitoring
infrastructure
A digital and physical review of active and inactive NRRRF infrastructure was completed as
part of the Site's design. NRRRF conducts surface water testing in pre -defined locations
along Site Features and within proposed conservation easements. These activities are
consistent with allowable activities of the proposed conservation easement.
Appendix B includes written confirmation outlining DWR's allowance for the City to place a
conservation easement over the subject parcels including fields currently permitted for the
application of biosolids. Areas historically used for biosolid application within the Site
footprint will be removed from the City's NPDES permit.
NRRRF existing agricultural
ponds & BMP infrastructure
Phase A — One in -line pond is located along Main Tributary 2 (Pond 2). Pond 2 has a direct
hydrological connection to downstream waters via a stabilized channel which outlets the
pond on its northern side. An existing concrete drop structure is in the southeast corner of
the pond and drains to a constructed wetland located down valley. Water that enters the
constructed wetland is filtered through the facility and outlets through a subsurface pipe.
The pipe runs underground, towards the "Main Tributary 2" Feature, and discharges into a
stable outlet before entering the feature (Figure 5 and Photos 5-7, Appendix A).
The proposed conservation easement includes all of Pond 2 and the outlet pipe for the
constructed wetland. Easement areas over these items are designated Maintenance
Easements and allow for access and maintenance. No RBC or NOC will be generated within
designated Maintenance Easements.
Dilapidated/
abandoned agricultural
infrastructure and earthen
farm roads
Dilapidated and abandoned agricultural infrastructure items are detailed in the Restoration
Plan (Section 3).
Earthen roads (farm paths) exist throughout the Site and are typically found along forest
edges — Section 3, Restoration Plan, details the removal and restoration of farm paths.
Existing culverted farm paths required to maintain hydrologic connectivity on ephemeral
channels and ditches will be identified and protected under the Conservation Easement.
Table 8 Note: All utility easements will be shown on the Conservation Easement Plat & Parcel's As -Built Survey and
sealed by a licensed surveyor of North Carolina.

The biological conclusion is no effect on the species listed above, and proposed mitigation activities will
result in positive benefits for these species through improved habitat and water quality.
2.4.2 Cultural Resources
The term "cultural resources" refers to prehistoric or historic archaeological sites, structures, or artifact
deposits over 50 years old. "Significant" cultural resources are those that are eligible or potentially eligible
for inclusion in the National Register of Historic Places. Evaluations of site significance are made with
reference to the eligibility criteria of the National Register (36 CFR 60).
Field visits were conducted in June 2020 to ascertain the presence of structures or features that may be
eligible for the National Register of Historic Places. No structures were found. An online search using the
North Carolina State Historic Preservation Office's (SHPO) Web GIS Service (http://gis.ncdcr.gov/hpoweb/)
and the National Register of Historic Places GIS Search
(https://www. nps.gov/maps/full.html?mapld-7ad17cc9-b808-4ff8-a2f9-a99909164466) identified zero
structures within the Parcel boundaries or within 1 mile of the Parcel (Appendix F).
3.0 Restoration Plan
The primary goals associated with the restoration of riparian areas within the Bank Parcel will focus on
improving water quality, enhancing flood attenuation, and restoring wildlife habitat. These goals will be
achieved by restoring and preserving forested riparian areas adjacent to stream channels, in -line ponds,
and ephemeral channels (Figure 8, Appendix A).
Goals will be accomplished by the following:
1. Removing nonpoint sources of pollution associated with agricultural production, including;
a. Ceasing the broadcast application of class B biosolids, fertilizer, pesticides, and other
agricultural materials into and adjacent to Parcel Features.
b. Providing a restored buffer to filter runoff from adjacent lands.
2. Reducing sedimentation within onsite and downstream receiving waters by reducing bank
erosion, vegetation maintenance, and agricultural land disturbances by ceasing agricultural and
current land use activities.
Raleigh Farm — Phase A Bank Parcel Development Plan (2019-1692 V4) Page 9 of 17
Neuse River Basin 8-Digit HUC: 03020201
3. Promoting floodwater attenuation by increasing frictional resistance of floodwaters crossing
Parcel floodplains.
4. Improving aquatic habitat by enhancing stream bed shading and natural detritus input.
5. Providing a terrestrial wildlife corridor and refuge in an area extensively disturbed by agricultural
practices.
6. Restoring and re-establishing natural community structure, habitat diversity, and functional
continuity.
7. Protecting the Parcel's riparian buffer functions and values in perpetuity.
Primary components of the Restoration Plan include:
1. Removal of dilapidated/abandoned agricultural infrastructure within forested areas where
feasible,
2. Removal of existing compacted earth roads associated with agricultural use,
3. Parcel -wide soil preparation & herbaceous vegetation treatment,
4. Riparian area restoration (replanting) extending from the top of bank (TDB) out 200' where
applicable and,
5. Parcel protection in perpetuity through a permanent conservation easement.
Table 8 details the Restoration Plan activities.
Table 8. Restoration Plan Activities
Restoration
Plan Activity
Phase Specific Actions
Herbaceous
Treatment
The City, which actively self -manages the farm operations, will treat Bermuda and fescue grasses
within the Parcel ahead of planting efforts. Treatment will consist of a broadcast application using
Roundup Custom (Glyphosate) at a rate of 3% and a surfactant of AgriDex at a rate of 1%, per acre,
mixed with water.
Removal of
Existing
Infrastructure
Remove existing farm paths within the proposed easements by deep ripping to break soil
compaction associated with equipment and vehicle use. NRRRF will establish new roads
dependent on future use and need outside of the Site's proposed easements.
- Remove rock debris associated with a historic farm path across Feature 2B, and stabilize the
channel with matting, ternporary/permanent seeding, and live -stake planting.
- Remove large debris from the easement as is feasible and without damaging the existing
riparian buffer (Main Tributary 2).
Riparian
Restoration
Within the Site's proposed conservation easements:
- Treat Bermuda and fescue grass species within active pasture areas (see Herbaceous
Treatment note above).
Site -wide discing of agricultural and pasture areas ahead of planting — discing will occur parallel
to the Site Features, promoting floodwater attenuation by increasing frictional resistance of
floodwaters crossing Parcel floodplains.
Establishment of a native herbaceous community via site -specific seed mix (See Planting Plan —
Section 3.3.1)
Establishment of a native hardwood forest via the planting of bare -root saplings from the top

3.3 Planting Plan
Restoration of the riparian area allows for recolonization and expansion of characteristic species across
the landscape. The riparian areas will be restored according to the Consolidated Buffer Mitigation Rule
15A NCAC 02B .0295 (November 1, 2015). The planting plan for the riparian restoration area includes
planting 28,000 native bare -root hardwood saplings across 46.51 acres at a Parcel density of +/-600 stems
per acre and live stakes for stream bank stabilization where necessary (Figure 8, Appendix A). Community
associations utilized in the proposed planting plan include Schafale and Weakley's (2012) Mesic Mixed
Hardwood Forest (Piedmont Subtype) and Piedmont Bottomland Hardwoods, as detailed in Section 2.3,
Existing Vegetative Communities. Species composition includes native species known for fruit production.
Tree species will be mixed thoroughly before planting to provide a diverse and random plant across the
Site. Planting density is set to ensure sufficient diversity and density of planted stems outlined in Rule 15A
NCAC 02B .0295 of 260. No one tree species will be greater than 50% of the established stems —Table 11
details tree species reserved by the Sponsor for planting. The final planted species is subject to final
species availability. The Sponsor will note any changes to the planting list in the Site's Baseline Document
and As -built Survey.

3.3.1 Permanent Seed Mix
The Sponsor will broadcast a permanent seed mix over all riparian restoration areas. The seed mix will
include native grasses and forbs, with a variety of annual and perennial plants known to benefit wildlife
and pollinators. The grass seed component will focus on low -growing species that favor establishing the
target forest community, particularly species such as purpletop (Tridens flavus) and bentgrass (Agrostis
hyemalis). The forb component will include a diverse mixture of native and naturalized forbs and
wildflowers, including fifteen or more species.
3.4 Parcel Protection & Easement Boundaries
Before the release of any credits, RS will record a permanent conservation easement at the Wake County
Register of Deeds sufficient to ensure protection, operation, and maintenance of restored riparian buffers
and other riparian areas in perpetuity.
Raleigh Farm — Phase A Bank Parcel Development Plan (2019-1692 V4) Page 12 of 17
Neuse River Basin 8-Digit HUC: 03020201
The form of the conservation easement shall be consistent with the standards employed by the State of
North Carolina in the protection of restored riparian buffers and riparian areas and shall be approved by
the DWR before the release of any credits.
Appendix B includes written confirmation from NCDWR approving of the implementation of this plan on
portions of fields currently permitted for the application of biosolids under NCDWR permit WQ0001730 -
City of Raleigh. Fields currently permitted for the application of biosolids will be removed from the City
of Raleigh's above referenced permit after the conservation easement is recorded and prior to approval
of this Bank Parcel's As -Built report by NCDWR.
Parcel easement boundaries will be identified in the field to ensure a clear distinction between the Parcel
and adjacent properties/land uses. The Sponsor will install marking and signage of the easement boundary
adjacent/close to utility and greenway easements to ensure the clear designation of the easement.
Boundaries may be identified by cattle fence, marker, bollard, post, tree -blazing, or other means as
allowed by Site conditions and/or conservation easement requirements and will be installed before the
As -Built Site visit by DWR. 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 and reported to DWR.
3.5 As -Built Report
A Baseline Monitoring Document and As -Built Survey will be submitted to DWR documenting the
completion of the Site's Restoration Plan and in accordance with the MBI.
4.0 Monitoring and Maintenance Plan
4.1 Monitoring Protocol & Success Criteria
Restoration monitoring procedures for vegetation will monitor plant survival and species diversity.
Quantitative sampling will include thirty-seven (37) permanent 10 x 10-meter vegetation plots as outlined
in the CVS Level 1-2 Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008) and will occur no
earlier than Fall of each year (Figure 10 - Monitoring Plan). Vegetation plot placement will adequately
represent riparian buffer credit and nutrient offset credit areas. A reference photo will be taken from the
origin point of each plot. All planted stems in the plots will be marked with flagging tape and recorded.
Data collected will include species, height, vigor, and planting type (planted stern and/or volunteer).
Monitoring of the restoration efforts will be performed for five years or until success criteria are fulfilled.
The Sponsor shall submit to DWR annual monitoring reports no later than December 31 of each year. Each
report will document the success of the vegetation and any maintenance, supplemental planting, or
encroachment within the easement areas. Success criteria within the riparian restoration areas will be
based on the survival of planted species at a density of 260 stems per acre after five years of monitoring.
The first annual monitoring activities will commence at the end of the first growing season, at least six
months after planting has been completed.
4.2 Parcel Maintenance
A remedial action plan will be developed and implemented with the approval of DWR in the event the
Parcel or a specific component of the Parcel fails to achieve success criteria as outlined above. Other
vegetation maintenance and repair activities may include pruning, mulching, and fertilizing. If exotic
invasive plant species require treatment, such species will be controlled by mechanical (physical removal
with the use of a chainsaw) and/or chemical methods (aquatic approved herbicide) in accordance with
North Carolina Department of Agriculture (NCDA) rules and regulations.
Raleigh Farm — Phase A Bank Parcel Development Plan (2019-1692 V4) Page 13 of 17
Neuse River Basin 8-Digit HUC: 03020201
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 Neuse Buffer Zones 1 and 2 to ensure
that no buffer violations have occurred.
4.3 Maintenance Areas
City of Raleigh actively manages areas surrounding the site, including the monitoring of existing
groundwater monitoring wells located around and within the Site footprint, as required under their
Non -Discharge Permit for biosolids application # WQ0001730 as well as the permit's corresponding
Corrective Action Plan issued 9/2/2010 by DWR. Raleigh shall retain rights to passive access to monitor
and maintain wells for compliance with the permit, the permit's corresponding "Corrective Active Plan
for the NRRRF" and any parts of 15A NCAC 02L .0107 (e) as applicable. Well reference #s and locations
within the Site footprint are as follows:

Additionally, maintenance areas will be delineated on the final survey to be included in the conservation
easement footprint, and excluded from nutrient offset and riparian buffer credit generation. These areas
are reserved for infrastructure maintenance such as earthen dams, culverted crossings, and piped
discharges. Land clearing and vehicular traffic in these areas necessary for infrastructure maintenance is
allowed.
4.4 Long Term Management Plan
The conservation easement will preserve all areas and prohibit all use of the property inconsistent with
its use as a nutrient offset and riparian buffer mitigation property, including any activity that would
materially alter the biological integrity of the Site/Parcel. RS will transfer or assign the conservation
easement and its interests in perpetuity to a qualified holder under NC General Statute ("GS") 121-34 et
seq. and 170(h) of the Internal Revenue Code prior to the submittal of the As -Built Report. The holder
shall be a land trust or stewardship program that is accredited by the Land Trust Accreditation Commission
and/or has been approved by DWR. A land trust must be certified under 501(c)(3) of the Internal Revenue
Code.
5.0 Financial Assurance
As required by the UMBI, the Sponsor will secure all financial assurances according to the UMBI. No
bond shall be less than $150,000 to cover costs of construction and no less than $100,000 to cover
monitoring expenses.
Monitoring bonds shall be renewed with confirmation of renewal provided to DWR with each annual
monitoring report. DWR reserves the right to alter the credit release schedule if monitoring reports
are submitted without proof of bond renewals.

6.0 Mitigation Potential
The Parcel will generate Neuse River Riparian Buffer Credits (RBC) and Nutrient Offset Credit (NOC,
nitrogen) on restored riparian areas measured from the top of bank out perpendicularly 200-feet on
Parcel Features (streams, ephemeral channels, and an in -line pond). Per the Consolidated Mitigation
Buffer Rule, the Parcel will generate RBC via allowed activities under Section (n), Non -forested Areas
[Restoration Site] and (o), Alternative Buffer Mitigation Options. Specifically, RBC is to -be generated from
sub -sections (o)(4), (o)(5), & (o)(7). Parcel compliance with these sub -sections is detailed below.
(o)(4) — Preservation of Buffer on Non -Subject Streams: Preservation of buffers on intermittent or
perennial streams that are not subject per 15A NCAC 02B .0233 are proposed via the permanent
protection under a perpetual conservation easement from cutting, clearing, filling, grading, and similar
activities that would affect the functioning of the buffer. Features proposed under (o)(4) were confirmed
as intermittent or perennial streams by DWR representatives during the June 2-3, 2020 site visit for
applicability and suitability (Appendix B). The area of preservation credit is capped at 25 percent of the
total area of buffer mitigation.
(o)(5) — Preservation of Buffers on Subject Streams: Buffer preservation is proposed on streams that are
subject per 15A NCAC 02B .0233 to permanently protect the buffer from cutting, clearing, filling, grading,
and similar activities that would affect the functioning of the buffer beyond the protection afforded by
the existing buffer rules on sites that meet the definition of a preservation site. The area of preservation
credit is capped at 25 percent of the total area of buffer mitigation.
(o)(7) — Mitigation on ephemeral channels: The Parcel will generate riparian buffer credit on "ephemeral
channels" as defined as a "natural channel exhibiting discernible banks within a topographic crenulation
(V-shaped contour lines) indicative of natural drainage on the 1:24,000 scale (7.5 minute) quadrangle
topographic map prepared by the US Geologic Survey, or as seen on digital elevation models with contours
developed from the most recent available LiDAR data" (15A NCAC 02B .0295). Appendix A Figures depict
the delineated watershed draining to each ephemeral channel proposed for RBC (Features 1A, 2A, 3A, 4A,
and GA). The entire area proposed for RBC from ephemeral channels is within the contributing drainage
area. All subject ephemeral channels are directly connected to an intermittent or perennial stream, are
contiguous with the Site and are proposed for permanent protection under the Site's conservation
easement. The RBC derived from ephemeral channels will not total more than 25 percent of the total area
of buffer mitigation. The proposed buffer credit areas meet all applicable requirements of Paragraph (n)
of Rule [15A NCAC 02B .0295] for restoration or enhancement, and all applicable requirements of
Subparagraph (o)(4) or (o)(5) of Rule [15A NCAC 02B .0295] for preservation. Ephemeral features were
confirmed by DWR representatives during the June 2-3, 2020 site visit for the applicability and suitability
of Site Features (Appendix B).
DWR has determined the nitrogen abatement of restored riparian areas on this Bank Parcel to be 2,273.02
lbs. per acre as agreed to in the Raleigh Farm MBI. RBC will be measured to the nearest whole square foot.
Riparian buffer restoration credits can be converted and transferred to NOC upon approval from DWR.
However, conversions of NOC from widths 101'-200' (measured from top of bank) to RBC will not occur.
Provided in Appendix B is a complete DWR Credit Determination Table, which details the individual
components, generated credit, and which features generating RBC credit comply with criteria to also be
convertible to NOC. The Sponsor must request and receive written approval of the conversion and transfer
of any mitigation credits from DWR prior to adding or removing credits from the ledgers.
Raleigh Farm — Phase A Bank Parcel Development Plan (2019-1692 V4) Page 15 of 17
Neuse River Basin 8-Digit HUC: 03020201
The Sponsor will maintain three individual ledgers, one to account for riparian buffer restoration credits,
one to account for riparian buffer preservation credits, and one to account for NOC. All credit assets shall
be accurately depicted on these credit ledgers. All accounting will be in accordance with DWR's Clarified
Procedures for Calculating Buffer Mitigation Credits and Nutrient Offset Credits (November 2019) (link in
UMBI). The complete DWR Mitigation Credit Table is shown on the following page, Table 13.

Project Name: Raleigh Farm Site Phase A
Address: 8599 Old Baucom Rd. (SR 2542), Raleigh, NC 27610
Location: 35.702396, -78.496346 (south of the road)
Site Inspection Date: 6/2/20 and 6/3/20
Dear Mr. Jenkins:
On June 2 and 3, 2020, Shelton Sullivan of the Division of Water Resources (DWR) conducted an on -site
review of features located on the subject property at the request of Barrett Jenkins with Restoration
Systems, LLC to determine the applicability to the Neuse Riparian Area Protection Rules, Title 15A North
Carolina Administrative Code 02B .0714.
The enclosed map(s) depict the feature(s) evaluated and this information is also summarized in the table
below. Streams were evaluated for being ephemeral, at least intermittent, and subjectivity to the Neuse
Riparian Area Protection Rules. Streams that are considered "Subject" have been located on the most
recently published NRCS Soil Survey of Wake County and/or the most recent copy of the USGS
Topographic (at 1:24,000 scale) map(s), have been located on the ground at the site, and possess
characteristics that qualify them to be at least intermittent streams. Features that are considered "Not
Subject" have been determined to not be at least intermittent, not present on the property, or not
depicted on the required maps.
This determination only addresses the applicability to the buffer rules and does not approve any activity
within buffers or within waters of the state. There may be other streams or features located on the
property that appear or do not appear on the maps referenced above. Any of the features on the site
may be considered jurisdictional according to the US Army Corps of Engineers and subject to the Clean
Water Act.
The following table addresses the features observed and rated during the DWR site visit:

Re: Site Viability for Buffer Mitigation & Nutrient Offset — Raleigh Farm Phase A Site
Near 8599 Old Baucom Rd (SR 2542), Raleigh, NC 27610
Lat., Long. 35.702396, -78.496346 (south of road)
Neuse 03020201
Dear Mr. Jenkins,
On February 11, 2020, Katie Merritt, with the Division of Water Resources (DWR), received a
request from you on behalf of Restoration Systems, LLC (RS) for a site visit near the above -
referenced site in the Neuse River Basin within the 8-digit Hydrologic Unit Code 03020201. The site
visit was to determine the potential for riparian buffer mitigation and nutrient offset within a
proposed Easement Boundary, which is more accurately show n in the attached map labeled
"CORPUD-Site Features Phase A" prepared by RS and edited by DWR. On June 2, 2020 and June
3, 2020, Ms. Merritt performed site assessments of the subject site and identified the following site
constraints:
• UTILITIES: Gas lines are being proposed on parts of the site where streams are located.
Existing powerline easements are also present. Specific locations and associated
easements of gas lines were unknown at the time of the DWR site visit, but the attached
CORP U❑ figure details where the proposed and temporary easements 1,1. ill be located.
• PERMITS: State. Federal and/or Local permits may be associated with this property.
Wetland delineation flagging and other stream call determinations were observed on the
site.
• EXISTING INFRASTRUCTURE: The City of Raleigh owns the property on the site
and has used the land for applying biosolids associated with the Neuse River Resource
Recovery Facility (NRRRF). Existing underground and above ground infrastructure is
present for purposes of irrigating the property. The City of Raleigh Public Utilities
Department (CORPUD) manages the property. Existing dirt paths, culverted crossings,
deeded access roads and greenways are present throughout and are adjacent to ditches
and stream onsite where mitigation would be proposed. Some Groundwater Monitoring
Wells were located onsite, but their locations are not depicted on any maps attached to
this correspondence. All existing infrastructure within the proposed conservation
easement shall be delineated and included as parr of the site's restoration plan along with
specific details on management and maintenance and what will be included or excluded.
o Application of bio-solids will not be permitted within a conservation easement.

o Impervious surface will not be permitted within a conservation easement unless it
is an access easement or located outside of creditable areas for mitigation or
nutrient offsets.
o Disruption in connectivity between top of bank and adjacent riparian areas will
not be permitted within a conservation easement.
❑ Monitoring wells must remain fully functional and shall be allowed to be
maintained and accessed as needed.
• BMP: A constructed wetland is present onsite adjacent to Pond 2 and shall not be
included in planting efforts or as creditable areas for mitigation or nutrient offset.
Ms. Merritt's evaluation of the features onsite and their associated mitigation determination for the
riparian areas are provided in the table below. This evaluation was made from Top of Bank (TOB)
and landward 200' from each feature for buffer mitigation pursuant to 15A NCAC 02B .0295
(effective November 1, 2015) and for nutrient offset credits pursuant to 15A NCAC 02B .0703.

Determinations provided in the table above were made using a proposed easement boundary shoeing
proposed mitigation areas shown in Figure 1, Figure 2 and the CDRPUD map. Maps representing the
proposal for the Site are attached to this letter and are initialed by Ms. Merritt on September 24, 2020.
Substantial changes to the proposed easement boundary as well as site constraints identified on page 1
of this letter could affect the Sites potential to generate buffer and nutrient offset credits.
This letter does not constitute an approval of this Site to generate buffer and nutrient offset credits.
Pursuant to 15A NCAC 02B .0295, a mitigation proposal and a mitigation plan shall be submitted to
DWR for written approval prior to conducting any mitigation activities in riparian areas and/or surface
waters for buffer mitigation credit. Pursuant to 15A NCAC 02B .0703, a proposal regarding a proposed
nutrient load -reducing measure for nutrient offset credit shall be submitted to DWR for approval prior
to any mitigation activities in riparian areas and/or surface waters.
All vegetative plantings, performance criteria and other mitigation requirements for riparian restoration,
enhancement and preservation must follow the requirements in 15A NCAC 02B .0295 to be eligible for
buffer and/or nutrient offset mitigation credits. For any areas depicted as not being viable for nutrient
offset credit above, one 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 in accordance with 15A NCAC 02B .0703.

The project is still in house with us at the moment, I believe we are still waiting on one more thing froth the additional
information request not related to the buffer restoration project.
You are right, the permit will reference this project and have a condition that a permit modification shall be submitted
to formally remove the sections that are a part of the buffer project. I don't know if we necessarily have authority to
provide the approval for the implementation of the plan, but we have no objections to the implementation as long as it
is removed from the permit and the final easement is sufficient. Katie mentioned that our office and hers would work
internally to provide you with assistance with the easement language that we would require.
As for what we might need from you, the only other comment I had for the CoR's response was that there was not an
updated acreage table for the residuals land application fields after the conservation easement goes into effect. I see
that there are certain amount of acres that are considered overlap on the maps, but I would still want the post -
easement acres in a nice table to put into our permit. I know Marla had also mentioned that some of the fields would be
too small and would be removed altogether, so CoR should propose which of those fields should be removed altogether.
Let me know if you have any other questions.

Erick,

I am working on a final draft for our buffer restoration/nutrient offset project on Raleigh's NRRRF property and wanted
to check in with you to see if Raleigh had completed their biosolids application permit renewal and if that renewal
mentioned future plans to implement the buffer restoration project as discussed?
We are looking for written approval from you to allow us to implement our restoration plan and then have Raleigh apply
for a permit modification to formally update the spray field maps after our conservation easement is recorded.
Please let me know where things stand from your end and if I can provide anymore information.
Katie Merritt, who is permitting our restoration project is cc'd as well as Marla Dalton with Raleigh Water.
Thanks,

Katie, it's kind of my fault, my additional information asked for them to provide a draft excerpt of the future
conservation easement. I'm not familiar with how your process works so I threw it back on the City of Raleigh to provide
it to me. I didn't ask for anything final regarding the easement, just a draft to ensure the easement would fall within the
scope of our rules. We won't approve anything based on what we receive, it was kind of meant to be a launching point
to make sure it was known that the easement would need special considerations and language to address the
requirements of our program.
Mr. Barrett,
We recognize that whatever maps you send aren't finalized at the moment. I expect we will issue the permit with a
condition for Raleigh to provide a permit modification to formally remove those areas from the permit to get the
finalized version. We just want to anticipate the removal of certain land application areas now so that we have
something concrete in place to help formalize their removal later on. Just to be clear though, Raleigh should be
providing this information to me, so you may want to provide this information to them because they are supposed to
provide a "Post -buffer mitigation map" which shows what land application areas will still be permitted after this action is
done.
As for the language you provided, it'll probably need to get edited to conform with our rules, but this can be done down
the line if needed. It looks to be missing provisions allowing for the State to enter the site for groundwater monitoring
and remediation activities, which is a requirement in the 02L .0107 groundwater rules. The bolded language only
appears to grant Raleigh that kind of access. Again, that's just off the top of my head and is in no way comprehensive,
and well discuss with Katie and probably the Groundwater Section to determine what all needs to be included in the
final easement. We'II also discuss your other final questions regarding the level of restriction and specific easement
language.

Hey Barrett,
Just as a side note, I will be taking the lead on providing RS with language for the conservation easement
associated with the Proposed Mitigation Bank. Therefore, Erick, Nathanial and I will work internally together
on what that language needs to be before sending anything to RS. Then, I will contact RS directly with the
suggested language to include and we can discuss. At this time, DWR is not ready to engage in assistance with
the conservation easement since there is not yet an MBI or Plan approved for the Bank yet. Once we get those
documents finalized, DWR staff will meet to go over the necessary changes to the current easement template.
Unless I have misunderstood, I don't believe Raleigh is required to have a conservation easement recorded to
get the permit renewed.
Let's plan to talk more about this next week at our teams meeting.
Thank you,
Katie

Erick,
Please find attached two draft maps showing areas in which the proposed conservation easement overlaps with existing
fields approved for residuals application. At this point our conservation easement is in draft form and we don't
anticipate finalizing until later this year. Is it okay to provide you updated maps of the changes in the residual
application field boundaries after the Conservation Easement Survey is finalized? This may not coordinate with Raleigh's
permit renewal schedule exactly. I'm asking to make sure I understand what we need to do but also when. Are these
maps sufficient for Raleigh residuals permit renewal that is in process?
Also attached is the draft conservation easement which already includes the below language:

Subject Clarified Procedures for Calculating Buffer Mitigation Credits & Nutrient Offset Credits for
Riparian Projects Regulated under 1 SA NCAC 02B .0295 and 15A NCAC 02B .0240
This letter, and the included attachments, outlines procedures and provides guidance for calculating
buffer mitigation credits and nutrient offset credits for projects submitted to the Division of Water
Resources (DWR) for review. In March 2019, the DWR established a small Work Group ("Group")
consisting of 7 people to discuss crediting inconsistencies for nutrient offset and buffer mitigation
projects. The Group consisted of 3 staff members from DWR, two staff members from the Division
of Mitigation Services, and one representative from each of two private mitigation banks. The
procedures and guidance provided in this Ietter were made by consensus from the Group for
implementing 15A NCAC 02B .0295 ("Rule .0295") and 15A NCAC 02B .0240 ("Rule .0240).
These procedures are for implementing buffer mitigation or nutrient offset projects where a
draft mitigation plan or a draft Bank Parcel Development Plan (BPDP) is submitted to the
DWR for review after the date of this letter. All other projects must comply with mitigation
plans and BPDPs submitted to DWR for review prior to the date of this letter.
A summary of the issues resolved by the Group and associated guidance for credit calculations are
detailed in Attachment A "Issues and Resolutions Ver 1.0 — Buffer Mitigation & Nutrient Offset".
For further information regarding this correspondence, please contact Katie Merritt with DWR at
katie.merritt(aincdenr.gov or by phone at 919-707-3637.

Issue #1: Procedure for crediting mitigation activities within riparian areas for buffer
mitii2ation and nutrient offsets.
Applying ratios and reductions under 15A NCAC 02B .0295 (m) and (n) respectively for buffer
mitigation credit, while also applying the DWR-Methodology and Calculations for determining
Nutrient Reductions associated with Riparian Buffer Establishment
https:I/files.nc.gov/ncdeq/Water%20Quality/Planning,NPU/Nutrient%20Qf]set%2ORu/e1A.-Bulfer-
Credit.pdf often leads to differences in measuring and accounting. Establishing procedures on how
credits are measured, calculated, converted and presented in mitigation plans involved addressing
inconsistencies and creating guidance on rounding, significant digits, units of measurement, as well
as developing credit ratios and conversion ratios.
Resolution: Established (a) guidance for rounding & decimal places, (b) guidance for physical
measurements, (c) buffer mitigation credit ratios, (d) credit conversion ratios, (e) formula for credit
conversions, and (f) a format for presenting credits.

Issue #2: Clarifications to DWR response to Item I. of the March 10, 2017 memorandum to
DMS from DWR titled "DWR Responses to Questions from DMS regarding implementation of
the Consolidated Buffer Mitigation Rule (15A NCAC 02B)" provided in Attachment D.
DWR issued a memo to DMS on March 10, 2017. Item I of this memo clarifies how to calculate the
25% of the total area of buffer mitigation cited under 15A NCAC 02B .0295 (o)(4), (o)(5) to achieve
the allowed amount of preservation area. Examples on how to calculate the Total Area of Buffer
Mitigation (TABM) and the Eligible Preservation Area (EPA) are included. However, the memo
does not address when applicable credit ratios and credit reductions provided in 15A NCAC 02B
.0295 (m) and (n) should be applied to the TABM to achieve the EPA.
Clarification: To achieve the EPA, the TABM is calculated by measuring the area of Restoration
(R) and Enhancement (E) before applying any credit ratios and credit reductions provided in 15A
NCAC 02B .0295 (m) and (n).
Example: [2 acres (R) + 1 acre (E)] / 0. 75 = 4 acres (TABM)
4 acres (TABM) * 0.25 =1 acre (EPA)
1 acre (P) + 3 acres (RIE) = 4 acres total

MEMORANDUM
To: N.C. Division of Mitigation Services
From: 5. Jay Zimmerman, N.C. Division of Water Resources Director
Subject: DWR Responses to Questions from DMS regarding implementation of the
Consolidated Buffer Mitigation Rule [15A NCAC 02B .0295]
On November S, 2016, the Division of Mitigation Services (DMS) met with the Division of Water
Resources (DWR) to discuss questions they had regarding implementation of the Consolidated
Buffer Mitigation Rule [15A NCAC 0213 .0295]. Below is a short summary of each question and
DWR's response.
I. Calculation of "25% of the Total Area of Buffer Mitigation"
15A NCAC 02B .0295 (o) (4) and (5) state "The area of preservation credit within a buffer
mitigation site shall comprise of no more than 25 percent of the total area of buffer mitigation."
DMS believes the following calculations should be used to determine the area eligible for
preservation:
Restoration (R) + Enhancement (E) + Preservation (P) = Total Area of Buffer Mitigation (TABM)
TABM * 0.25 = Eligible Preservation Area (EPA)
Example: 2 acres (R) + 1 acre (E) + 7 acres (P) = 10 acres (TABM)
10 acres (TABM) * 0.25 = 2.5 acres (EPA)
Response:
In the example above, 45% of the area of the site would come from preservation, with the
remaining 55% corning from restoration/enhancement:
2.5 acre (P) + 3 acres (R/E) = 5.5 acres total
Based on a review of the language in the rule, the documents throughout the rulemaking
process, including correspondence with OSBM on the fiscal note, areas where buffer
mitigation credits are not being generated Should not be used to calculate the "total area of
buffer mitigation."
The restoration or enhancement area shall be at least 75% of the area generating buffer
mitigation; the remaining 25% of the area generating buffer mitigation can be preservation:
75% (R/E) + 25% (P) = 100% TABM
Stele of North Carolina 1 Environmental Quality Water Resources
1517 Mail Servicc ('enter I Raleigh, North Carolina 27699.1617
919 807 ,300
Page2of3
To calculate the area eligible for preservation:
[Restoration (R) + Enhancement (E)] / 0.75 = Total Area of Buffer Mitigation (TABM)
TABM * 0,25 = Eligible Preservation Area (EPA)
Example: [2 acres (R) + 1 acre (E)] / 0,75 = 4 acres (TABM)
4 acres (TABM) * 0.25 = 1 acre (EPA)
1 acre (P) + 3 acres (RJE) = 4 acres total
II. Defining Breaks Between Restoration and Enhancement Areas
DMS asked for clarification on how DWR defines the breaks between restoration' and
enhancement2. Specifically, DMS asked whether drip lines were still used and whether
individual trees were excluded from restoration sites.
Response:
DWR has not considered the drip line to represent the outer edge of a wooded area for
several years. This was clarified in a memo from DWR to DMS in August 2013. Individual
trees do not need to be delineated and removed from the restoration area, rather DWR
looks for areas or zones when determining restoration, enhancement or preservation areas.
For example:
characterized by an absence of trees and by a lack of dense growth of smaller woody stems or
are characterized by scattered individual trees such that the tree canopy is less than 25% of the
cover and by a lack of dense growth of smaller woody stems
characterized by conditions between that of a restoration site and a preservation site such that
the establishment of woody stems will maximize nutrient removal and other buffer functions
Page 3 of 3
III. Prior Grazing
15A NCAC 02B .0295 (o)(6) describes enhancement of grazing areas adjacent to streams. It
states that the applicant or mitigation provider shall demonstrate that grazing was the
predominant land use since the effective date of the applicable buffer rule. DMS asked
when is the predominance of grazing demonstrated?
Response
15A NCAC 02B .0295 (1) states that the authority shall issue a mitigation determination that
specifies the area, type and location of the mitigation and the water quality benefits to be
provided by the mitigation site. During the on -site evaluation, DWR looks at existing
conditions to determine whether grazing has been a continuous land use in the proposed
mitigation area (e.g. hoof shear, manure, cattle fencing, etc.) since the effective date of the
applicable buffer rule. DWR also evaluates satellite imagery. If it is not clear to DWR that
grazing has been the predominant land use since the effective date of the applicable buffer
rule, ❑WR will ask for additional documentation (e.g. landowner documentation, photos,
maps, etc.).
If the grazing site is proposed for retroactive credit as described in 15A NCAC 0213 .0295
(o)(1), additional documentation of the pre-existing conditions may be required.
If there is a disagreement regarding the documentation requested by DWR, the request will
be elevated to the Water Quality Permitting Section Chief.
IV. Clarification of Use of 8-19-08 Diffuse Flow Clarification Memo
DMS asked for verification that the Buffer Interpretation Clarification Memo #2008-019,
issued August 19, 2008, was still eligible for use, and whether that method or an alternative
method as provided for in the rule could be used at the discretion of the project proponent.
Response:
The Suffer Interpretation Clarification Memo #2008-019, issued August 19, 2008, is still
eligible for use to comply with 15A NCAC 02B .0295 [lj{3).

Hey Raymond,
This email serves to acknowledge that two (2) in -line ponds associated with the Raleigh Farms A Site
& Raleigh Farms B-C Site are considered "not subject" to the Neuse Buffer Protection Rules due to
the fact that they are agricultural ponds and are therefore "exempt" from that Rule under Session
Law 2013-413 Section 52. Pond 5 on the Raleigh Farm B-C site and Pond 2 on the Raleigh Farm
A site are both "not subject" and therefore shall be referred as such in any Bank Parcel Development
Plans (BPDP) and corresponding Figures/Credit Tables submitted with the Plans. A site plan attached
to this email shows the ponds referenced above.
Thank you for you attention to this matter,
Katie

A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached 'Documented Occurrences' tables and map.
The attached `Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is documented within the project area or indicated within a one -mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water
Management Trust Fund easement, or an occurrence of a Federally -listed species is documented
near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rodney.butler@rlcdcr,gov or 919-707-8603.
Sincerely,
NC Natural Heritage Program
