4Q1 & BUFFER -PERMITTING
I. PREAMBLE
This Umbrella Mitigation Banking Instrument ("Instrument") regarding the establishment, use,
operation, and maintenance of two (2) Buffer Mitigation Bank Parcels, identified in Section II, to
provide Randleman Lake Riparian Buffer mitigation credits ("Riparian Buffer Credits") is made and
entered into by and among Wildlands Holdings V, LLC acting as the Bank Sponsor ("Sponsor"), and the
North Carolina Department of Environmental Quality - Division of Water Resources ("DWR"). This
Instrument is in accordance with the Consolidated Mitigation Rule 15A NCAC 02B .0295, which
became effective on November 1, 2015 (Attachment B).
The purpose of these Bank Parcels is:
A. To restore, enhancement and preserve riparian vegetation adjacent to streams and/or
agricultural ditches with the intent to improve water quality within the Randleman Lake
Watershed.
B. To convert agricultural land uses within riparian areas adjacent to streams and/or agricultural
ditches into a dense, hardwood vegetated state with the intent to significantly reduce nutrient
loadings associated with agricultural practices into streams and ditches.
C. To provide mitigation and sell any resulting Riparian Buffer Credits to third parties in the
Randleman Lake Watershed for development (both existing and proposed) requiring such
mitigation.
II. LOCATION AND GEOGRAPHIC SERVICE AREA
A. The Geographic Service Area ("GSA") is the designated area wherein a Bank can reasonably be
expected to sell Riparian Buffer Credits for buffer impacts due to development activities.
B. The GSA for this instrument is limited to the Randleman Lake Watershed of the Cape Fear River
Basin.
C. The selling of Riparian Buffer Credits shall be limited to the Randleman Lake watershed, as defined
in accordance with Rule 15A NCAC 0213 .0295.
D. The following table provides site-specific details of each of the two Bank Parcels proposed under
this Instrument, that are within the Randleman Lake Watershed;

III. AUTHORITIES
A. The Bank Parcels will be used to provide Riparian Buffer Credit in accordance with the
requirements in the DWR Authority document referenced herein as "Attachment A" and attached
to this Instrument.
Projects eligible for utilization of the credits are those requiring authorization under the
requirements of Attachment A and any subsequently approved North Carolina statutes and rules
for the Randleman Lake Water Supply Nutrient Management Strategy.
C. The selling of mitigation credits generated from the Bank Parcels approved under this Instrument
shall be consistent with approved North Carolina statutes and rules forthe Randleman Lake Water
Supply Nutrient Management Strategy.
D. Mitigation activities proposed under this Instrument and corresponding Bank Parcel Development
Packages (BPDP) to generate Riparian Buffer Credits shall be consistent with North Carolina
statutes and rules for the Randleman Lake Water Supply Nutrient Management Strategy that are
in place at the time a complete BPDP is submitted to DWR.
IV. ESTABLISHMENT OF THE BANK PARCELS
A. In accordance with 15A NCAC 02B .0295, DWR has provided a "Site Viability Letter" for each of
the Bank Parcels proposed under this Instrument. The Site Viability Letter is not an approval of
the site to generate mitigation credits, but is a preliminary review of the Bank Parcel that details
and confirms existing land use conditions, defines the riparian sites (Enhancement, Preservation,
or Restoration), and identifies features (streams, ditches, ponds, etc.) that meet general criteria
to be suitable to generate mitigation credits. Table 2.0 below outlines when a Site Viability Letter
was issued by DWR for the mitigation sites proposed under this Instrument:

standard of 260 stems per acre at the completion of monitoring. The final performance
standard shall include a minimum of four native hardwood tree species or four native
hardwood tree and native shrub species, where no one species is greater than 50 percent
of stems. Native hardwood and native shrub volunteer species may be included to meet
the final performance standard of 260 stems per acre. The Authority may approve
alternative vegetation plans upon consideration of factors, including site wetness and
plant availability, to meet the requirements of this Part;
(C) A grading plan (if applicable). The site shall be graded in a manner to ensure diffuse
flow through the entire riparian buffer;
(D) A schedule for implementation, including a fertilization and herbicide plan if applicable;
and
(E) A monitoring plan to document whether the site is expected to meet the final performance
standards as defined in Part (n)(2)(B) of this Rule and other anticipated benefits to the
adjacent water. The plan shall include a proposed schedule and method for monitoring
the vegetative status of the restoration or enhancement site for five years, including the
health and average stem densities of native hardwood tree or tree and shrub species that
are to be counted toward the final performance standard.
(3) Within one year after Authority approval of the mitigation plan, the applicant or mitigation
provider shall present documentation to the Authority that the riparian buffer has been restored or
enhanced unless the applicant or mitigation provider requests, and the Authority agrees in writing
prior to that date, to a longer time period.
(4) The applicant or mitigation provider shall submit written annual reports; unless an alternative

five years after completion of the activities identified in Part (n)(2)(B) of this Rule at the
restoration site or enhancement site showing:
(A) compliance with the monitoring plan approved pursuant to Part (n)(2)(E) of this Rule;
and
(B) that diffuse flow through the riparian buffer has been maintained.
If the Authority determines that the native hardwood tree or tree and shrub species at the site are not
expected to meet the final performance standards listed in Part (n)(2)(B) of this Rule, then the Authority
may require that the applicant or mitigation provider replace trees or trees and shrubs as needed during that
five-year period. If the Authority determines that diffuse flow through the buffer is not being maintained,
then the Authority may require that the applicant or mitigation provider restore diffuse flow. If the
Authority determines that the final performance standards listed in Part (n)(2)(B) of this Rule have not been
achieved at the end of the five-year monitoring period, the Authority may require additional years of
monitoring. The Authority shall make determinations referenced in this Subparagraph on a site specific
basis based on the annual reports, any supplemental information submitted by the applicant or mitigation
provider, or a site evaluation by the Authority_

mitigation provider shall provide an enhancement plan as set forth in Paragraph (n) of this Rule.
The applicant or mitigation provider shall demonstrate that grazing was the predominant land use
since the effective date of the applicable buffer rule.
(7) Mitigation on ephemeral channels. For purposes of riparian buffer mitigation as described in this
Part, an "ephemeral channel' is 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 U.S. Geologic Survey, or as seen
on digital elevation models with contours developed from the most recent available LiDAR data,
available at no cost at http://www.ncfloodmaps.com/lidar.com. Ephemeral channels only flow for
a short period of time after precipitation in the drainage area and do not have periods of base flow
Attachment B
sustained by groundwater discharge. The applicant or mitigation provider shall provide a
delineation of the watershed draining to the ephemeral channel. The entire area proposed for
mitigation shall be within the contributing drainage area to the ephemeral channel. The ephemeral
channel shall be directly connected to an intermittent or perennial stream and contiguous with the
rest of the mitigation site protected under a perpetual conservation easement. The area of the
mitigation site on ephemeral channels shall comprise no more than 25 percent of the total area of
buffer mitigation. The proposal shall meet all applicable requirements of Paragraph (n) of this
Rule for restoration or enhancement. The proposal shall meet all applicable requirements of
Subparagraph (0)(4) or (0)(5) of this Rule for preservation.
(8) Restoration and Enhancement on Ditches. For purposes of riparian buffer mitigation as described
in this Part, a "ditch" is defined as a man-made channel other than a modified natural stream that
was constructed for drainage purposes. To be used for mitigation, a ditch shall meet all of the
following criteria:
(A) be directly connected with and draining towards an intermittent or perennial stream;
(B) be contiguous with the rest of the mitigation site protected under a perpetual conservation
easement;
(C) stormwater runoff from overland flow shall drain towards the ditch;
(D) be between one and three feet in depth; and
(E) the entire length of the ditch shall have been in place prior to the effective date of the
applicable buffer rule.
The width of the restored or enhanced area shall not be less than 30 feet and shall not exceed 50
feet for crediting purposes. The applicant or mitigation provider shall provide a delineation of the
watershed draining to the ditch. The watershed draining to the ditch shall be at least four times
larger than the restored or enhanced area along the ditch. The perpetual conservation easement
shall include the ditch and the confluence of the ditch with the intermittent or perennial stream,
and provide language that prohibits future maintenance of the ditch. The proposal shall meet all
applicable requirements of Paragraph (n) of this Rule for restoration or enhancement.
(9) Stormwater Treatment Options. All stormwater treatment options shall meet the following
requirements:
(A) Structural options already required by other local, state, or federal rule or permit cannot
be used as alternative buffer mitigation credit, except to the extent such measure(s)
exceed the requirements of such rule or permit. Stormwater Best Management Practices
(BMPs), including bioretention facilities, constructed wetlands, infiltration devices and
sand filters are all potentially approvable BMPs by the Division for alternative buffer
mitigation credit. Other BMPs may be approved only if they meet the nutrient removal
levels outlined in Part (o)(9)(13) of this Rule. Existing or planned BMPs for a local, state,
or federal rule or permit may be retrofitted or expanded to improve their nutrient removal
if this level of treatment is not required by other local, state, or federal rules. In this case,
the predicted increase in nutrient removal may be counted toward alternative buffer
mitigation credit;
(B) Minimum treatment levels: Any structural BUT shall provide at least 30 percent total
nitrogen and 35 percent total phosphorus removal as demonstrated by a scientific and
engineering literature review as approved by the Division. The mitigation proposal shall
demonstrate that the proposed alternative removes an equal or greater annual mass load
of nutrients to surface waters as the buffer impact authorized in the authorization
certificate or variance, following the calculation of impact and mitigation areas pursuant
to Paragraphs (d), (e), and (f) of this Rule. To estimate the rate of nutrient removal of the
impacted buffer, the applicant or mitigation provider may use the "NC Division of Water
Quality — Methodology and Calculation for determining nutrient reductions associated
with Riparian Buffer Establishment" available at no cost at
http://portal.ncdenr.org/c/document_library/get_file?uuid=55c3 758f-5e27-46cf-8237-
47f890d9329a&groupId=38364. The applicant or mitigation provider may propose an
alternative method of estimating the rate of nutrient removal for consideration and review
by the Division;
(C) All proposed structural BMPs shall follow the Division's "2009 Stormwater Best
Management Practice Design Manual" available at no cost at
Attachment B
http://portal.nedenr.org/web/Ir/bmp-manual. If a specific proposed structural BMP is not
addressed in this Manual, the applicant or mitigation provider shall follow Chapter 20 in
this Manual for approval;
(D) All structural options are required to have Division approved operation and maintenance
plans;
(E) All structural options are required to have continuous and perpetual maintenance and
shall follow the Division's "2009 Stormwater Best Management Practice Design
Manual";
(F) Upon completion of construction, the designer for the type of BMP installed shall certify
that the system was inspected during construction and that the BUT was constructed in
conformity with plans and specifications approved by the Division;
(G) Removal and replacement of structural options: If a structural option is proposed to be
removed and cannot be replaced on-site, then a structural or non-structural measure of
equal or better nutrient removal capacity, as determined by calculations submitted to and
approved by the Division, in a location as specified by Paragraphs (f) and (g) of this Rule
shall be constructed as a replacement;
(I� Renovation or repair of structural options: If the applicant, mitigation provider, or the
Division determines that a structural option must be renovated or repaired, it shall be
renovated to provide equal or better nutrient removal capacity than as originally
designed; and
(I) Structural options, as well as their operation and maintenance, are the responsibility of
the landowner or easement holder unless the Division gives written approval for another
responsible party to operate and maintain them. Structural options shall be located in
recorded drainage easements for the purposes of operation and maintenance and shall
have recorded access easements to the nearest public right-of-way. These easements
shall be granted in favor of the party responsible for operating and maintaining the
structure, with a note that operation and maintenance is the responsibility of the
landowner, easement holder, or other responsible party.
(10) Approval for other alternative buffer mitigation options. Other alternative riparian buffer
mitigation options not specified within this Rule may be submitted to the Division for review and
recommendation to the Environmental Management Commission on a case-by-case basis. Any
proposal submitted under this Paragraph shall provide documentation or calculations to
demonstrate that the proposed alternative mitigation option removes an equal or greater annual
mass load of nutrients to surface waters as a riparian buffer. Upon completion of the Division's
review, and prior to recommendation to the Environmental Management Commission, the
Division shall issue a 30 -calendar day public notice through the Division's website and the
DWRwetlands Listserve. Division staff shall present their recommendations, including comments
received during the public notice period, to the Environmental Management Commission for a
final decision. If approved by the Environmental Management Commission, the alternative buffer
mitigation option may be proposed by other applicants and mitigation providers.
