RE: DMS Review comments for Mitigation Plan
Sassarixa Swamp Mitigation Site (DMS ID # 100040)
Neuse 03020201, Johnston County, NC
Contract No. 7425
Dear Mr. Dow,
Thank you for compiling and providing comments on the Sassarixa Mitigation Site draft Mitigation Plan.
The use of the term "buffer" or "riparian buffer" is used too loosely throughout the plan. These
terms should only be used to describe an area that is within the Neuse Riparian Buffer. For this
site, only the first 50' adjacent to streams subject to the rule are Neuse Riparian Buffers.
Therefore, please correct applicable references to "buffer" or "riparian buffer" and replace
incorrect references with "riparian areas" or "riparian restoration".
References to "buffer" or "riparian buffer" were corrected to "riparian areas"
and "riparian restoration".
2. The plan describes this site as a "Buffer Restoration Project" throughout the text. However,
most of the site is actually buffer enhancement w/some preservation. I recommend "buffer
mitigation project" or something other than "buffer restoration project" to avoid confusion.
References to "Buffer Restoration Project" has been replaced to "Buffer
Mitigation Project".
3. Section 2.2 page 6
This section is titled "Project Location", but it includes references to the Alternative
mitigation options being proposed onsite. I recommend separating this information out
into its own section.
"Project Location" has been separated out into "Project Location" and "Buffer
Project Attributes".
Some streams onsite are "not subject". Correct where applicable.
Corrected to include non -subject streams too.

c. Enhancement via Cattle Exclusion is also an alternative option that should be added to
this section.
Enhancement via Cattle Exclusion has been added as an alternative option.
d. For Ephemeral channels, last bullet, correct the rule reference to just be 15A NCAC 02B
.0295 (n). Currently, the reference to 0295 (o) is too inclusive. For example,
"enhancement" on Ephemerals can only be achieved by actually planting an area
deemed "Enhancement Site" under 0295 (n). Areas deemed as "Enhancement" via
cattle Exclusion are approved under 0295 (o) and cannot be achieved adjacent to
Ephemeral channels. T3 Ephemeral is currently proposed as "Enhancement via Cattle
Exclusion" and instead, should be Preservation according to viability letter.
The rule reference has been updated. T3 Ephemeral reach has been
changed to Preservation to match the viability letter.
e. For coastal HW Streams, add additional information.
i. The rule requires that the site meet success criteria for the stream mitigation.
Therefore, this area requires 7 years of monitoring instead of 5.
7 years of monitoring has been added
ii. The rule requires the creditable areas to be planted to get buffer credit adjacent
to HW streams. Therefore, areas currently forested on T5C must be excluded
from credit, and only the restoration areas in the fields are viable.
Forested areas along the HW streams have been excluded from credit.
iii. Text says the buffer will be measured based on valley length, but where is that
measurement provided or represented?
The valley length is shown in Figure 6 and Figure 7.
4. Section 2.5
a. The statement provided about the purpose of the internal crossings suggests that there
may should be fencing on both sides of Sassarixa creek. No fencing is shown on the plan
sheets or the figures for the right side of Sassarixa Creek. If "agriculture" in this section
implies cattle, then sassaixa creek will require fencing on both sides of the easement in
order to comply with 0295 (o)(6). Please explain.
Fencing has been added to the right side of Sassarixa Creek.
Section 5.2 & Plan Sheet 3.0 lists Green Ash to be planted. Based on concerns of the Emerald
Ash Borer and its ability to spread and attack saplings (>1-inch diameter), DWR highly
recommends this tree not be included in the planting plan.

Green Ash has been removed from the planting plan.
6. Provide a reasonable justification to plant Cypress trees, a softwood, which are not considered
an appropriate species to meet performance standards per 0295 (n)(2)(B). Provide specifics as
to where Cypress will be planted in the Plan Sheets.
Cypress has been removed from the planting plan.
7. Section 5.3 —
a. The viability letter notes that there are two types of enhancement on this project.
Enhancement under 0295 (n) indicates that the area requires plantings vs Enhancement
under 0295 (o)(6) requires just the removal of cattle. The upper reach of T4 was
determined to be Enhancement under 0295 (n). Other Enhancement areas met
.0295(o)(6). Correct figures where cattle exclusion is shown on the upper reach of T4
and show as "Enhancement". Confirm that the planting sheets show plantings in this
area as well.
The upper reach of T4 will also be planted.
b. How will cattle be "excluded" in the buffer enhancement areas?
It has been noted in Section 5.3 that cattle will be "excluded" through fencing.
c. Correct rule reference to be 15A NCAC 02B .0295(o). It currently reads .0296
Rule reference has been corrected.
8. Section 6.2 Please revise plan to add that planted stems in the monitoring plats will all be
flagged.
Flagging planted stems has now been noted in Section 6.2.
9. Table 9 — add another parameter to account for T5C needing 7 years of monitoring.
Table 9 is updated to reflect the 7 years of monitoring along T5C.
10. Section 7.1— Add that "height" will be measured to assess the vigor of stems.
Height has been added to assess the vigor of stems.
11. Section 7.4 — Add a note about T5C and its additional monitoring to meet performance
standards. The rule also requires that the stream mitigation meets the performance criteria by
the USACE as well. Therefore, DWR cannot accept the restoration area adjacent to T5C without
knowing it meets the final performance criteria at closeout by the IRT. Please indicate that

closeout of credits adjacent to T5C will be done at Closeout with IRT. If T5C is removed from the
buffer plan all together, then none of this applies.
The additional monitoring performance for T5C has been added.
12. Tables 7a & 7b
a. Use newer version to the table (request from DMS) and attempt to keep the table all on
one page. If needing to split 7a and 7b on separate pages that is fine. This may require
a larger paper size to accommodate this request. Please do not reduce the font size in
the table too much such that it makes the table difficult to read as hard copy.
Newer version of the table is now being used.
b. Correct table based on comments provided with this letter.
Corrections have been incorporated.
c. T4 should be "Enhancement" and not "Enhancement via Cattle Excl". See comment #7.
T4 is now "Enhancement".
d. Breakout T5C credits separate from others and as "not convertible to Nutrient".
T5C credits are now separated from the others and listed as "NOC".
e. T5C is not viable for Enhancement, remove from table.
Enhancement for T5C has now been removed.
f. T3 Ephemeral reach is not viable for Enhancement via Cattle Excl. Change this to
preservation.
T3 Ephemeral has been changed to preservation.
g. T4 & T5 Restoration 0-1000' are both shown with"**". Explain why these two are
different than other Restoration areas 0-100' shown in the table. If the explanation is
due to widths, then why can't the Min -Max width be shown as different?
The asterisks have been removed with the new table.
h. Formulas may be off on table, so once newer version of the table is completed for this
site, I will be able to decipher whether the subtotals and totals are compliant.

i. T2 restoration area may need to be edited based on comment #15 below.
Noted.
13. Paragraph below Table 7b will need to be edited based on comments made in this letter.
Specifically, the viability of certain streams/reaches that are stated incorrectly in the first
sentence.
The paragraph below Table 7b has been removed due to the clarification from
correspondence with Ms. Katie Merritt sent on August 16. 2019.
14. Table 7a-b shows nutrient offset conversions. However, there is no reference to this in the
introduction of the Plan. If this site is to be reviewed by DWR to generate nutrient and/or
buffer, please include language to the effect in the introduction.
Nutrient offset credits are not being request at this time, but areas may be
converted to nutrient offset credits by DMS later. Since nutrients are not being
requested at this time, language is not needed in the introduction. A note below
Table 7a has been added indicating potential nutrient request in the future.
15. Figure 6 —
a. Identify the location of the Ephemeral channel along T3.
The location of the Ephemeral channel along T3 has been noted.
b. Show Preservation instead of Cattle Excl. along T3 ephemeral reach.
T3 has been changed to Preservation.
c. Add Enhancement (non -cattle excl) along T4 (R1 & R2) (see plan sheet 3.3)
T4 (R1 &2) has been changed to Enhancement (non -cattle exclusion)
d. Remove Enhancement adjacent to T5C.
T5C Enhancement has been removed.
e. T2 restoration area should only be measured from Top of Bank of the Stream
Determination point by DWR or the "radius/bubble" above the point. When comparing
this area to Figure 7, the top of bank appears to be measured from the proposed stream
alignment beyond the wood line.
Figure 7 has been corrected to the Top of Bank of the Stream Determination
point by DWR.

1.0 Introduction
The Sassarixa Swamp Mitigation Site (Site) is a buffer mitigation and nutrient offset project in
conjunction with a stream mitigation project. Construction of the stream restoration project will occur
concurrently with planting and excluding livestock from the riparian buffers. The Site is located in
Johnston County approximately six miles southwest of Smithfield and five miles north of Four Oaks
(Figures 1). The Site is comprised of approximately 65.1 acres along Sassarixa Creek and seven unnamed
tributaries to Sassarixa Creek, along with six unnamed tributaries to Black Creek. Currently, the Site is
characterized by a mix of active pastures, fields, and woodlands. The project will restore, enhance, and
preserve riparian buffer area within the project area, which will provide 1,098,146.503 buffer credits or
55.9 acres worth of buffer mitigation.
The Site is located within the Hydrologic Unit Code (HUC) 03020201130030 and North Carolina Division
of Water Resources (NCDWR) Sub -basin 03-04-04 Sassarixa Creek and seven unnamed tributaries to
Sassarixa Creek, along with six unnamed tributaries to Black Creek on the Site flow into Holts Lake,
which drains to the Neuse River. Holts Lake is a recreational lake classified as a Nutrient Sensitive Water
(NSW) and the Neuse River is a water supply for the City of Goldsboro.
The Sassarixa Swamp Mitigation Site is located in a new Targeted Local Watershed (TLW) that is not
described in the 2010 Neuse River Basin Restoration Priorities (RBRP) Plan. The TLW was added in the
2015 Neuse 01 CU Update because there were more water quality issues than assets. Stressors for this
TLW include impervious surfaces, disturbed riparian areas, and agricultural land use/animal operations.
The Site addresses the TLW stressors of agricultural land use/animal operations and the lack of
protected riparian areas. The project will also address key Cataloging Unit (CU) wide restoration goals
for the Neuse River 03020201 described in the RBRP including reduction of sediment and nutrient loads
from agricultural lands and increasing or improving riparian buffers (NC DWR 2009).
This buffer mitigation project will reduce sediment and nutrient loading, improve terrestrial and in
stream habitats, and improve stream and bank stability. The area surrounding the streams proposed for
restoration is a mixture of active pasture, fields, and woodlands. By removing cattle access to onsite
tributaries to Holts Lake, restoring a forest to maintained riparian areas and protecting and preserving
existing forested areas; the project will
reduce nutrient and sediment inputs to
project streams, and ultimately to
Holts Lake. The restored floodplain
areas will filter sediment during rainfall
events. The establishment of riparian
areas will create shading to minimize
thermal pollution. Finally, invasive
vegetation will be treated within the
project area as needed and the
proposed native vegetation will
provide cover and food for wildlife.
2.0 Mitigation Project Summary
The major goals of the proposed buffer mitigation project are to provide ecological and water quality
enhancements to the Neuse River Basin by creating a functional riparian corridor and restoring the

2.1 Existing Site Conditions
The buffer mitigation project will place put 65.1 acres of agricultural fields and woodlands along
Sassarixa Creek and several unnamed tributaries that drain into the Holts Lake watershed, part of the
Neuse River Basin under a conservation easement. Out of the 65.1 acres, 55.9 acres will be proposed for
a combination of riparian buffer restoration, enhancement, and preservation.
The project includes several adjacent properties that have been owned and operated as a livestock farm
by a single family since 1850, where livestock are continually rotated through all fields (with access to
their associated streams). The western portion of the project includes Sassarixa Creek and seven
unnamed tributaries to Sassarixa Creek (T1, T1A, T1B, TIC, T1D, T2, and T3) (Figure 2). The eastern
portion of the site contains six unnamed tributaries to Black Creek (T4, T5, TSA, TSB, TSC, and T6). A
review of historic aerials from 1950 to 2012, located in the appendix, show that onsite streams have
existed in their approximate locations with very little change to riparian zones since 1950. Two

alterations to the Site visible from aerial photography are the addition of the pond on T2 between 1964
and 1973, and the addition of the large pond below TSA, TSB, and TSC, between 1950 and 1961.
Sassarixa Creek is a perennial stream that enters the Site from Black Creek Road and flows southeast. A
mature hardwood forest surrounds the stream on both sides.
T1 enters the site at Old Olive Road in the northeast section of the project. T1A and T1D enter the right
bank of T1, while T1B enters from the left bank downstream of T1A and T1D. The canopy is dominated
by loblolly pine (Pinus toedo) with an understory of Japanese stilt grass (Microstegium vimeneum).
TIC is a short reach that starts at the tree line and flows into Sassarixa Creek.
The origin of T2 is a farm pond located in the natural valley of this drainage area that is dominated by
fescue and hay production. There is a grass swale at the outlet of the pond, and once the swale reaches
the edge of the forest, there is a large (>5') headcut as it enters the valley of Sassarixa Creek.
A ditch originates south of Old Olive Road, flowing into T3 which starts as an ephemeral channel. T3
continues along a forested buffer transitioning into an intermittent stream. While the channel along T3
is forested, livestock access has impacted most of the understory.
T4 starts as an intermittent stream that enters the
Site through a culvert at Old Olive Road. Roughly
200 feet down the stream breaks and becomes a
degraded wetland picking back up another 300
feet to continue being an intermittent channel.
The upper portion of T4 has sporadic conifer trees,
while the understory has been trampled by cattle.
TSA, TSB, and T5C are the intermittent headwater
streams to T5. They originate in the northernmost
region of the project, upstream of a large pond. Their watersheds are primarily livestock grazing areas
and row crops.
T5 and T6 are intermittent streams that enter the project area at Old Olive Road. A mature hardwood
canopy extends the length of both streams.
2.2 Parcel Location
The Site is approximately six miles southwest of Smithfield and five miles north of Four Oaks (Figure 1).
The site is within the DMS targeted Neuse River Basin HUC 03020201130030 and NCDWR Subbasin 03-
04-04.
From Raleigh take 1-40 E. Take exit 319 for NC-210 toward Smithfield/Angier. Turn left onto NC-210 E
(signs for Smithfield). Continue on NC-210 E for 2.4 miles and turn right onto Lassiter Roads. After 4.6
miles, turn left onto Black Creek Road. Continue on Black Creek Road for 0.7 miles and then turn right
onto Old Olive Road. The first parcel is 0.1 mile on the right of Old Olive Road. The other parcels are at
various locations further down Old Olive Road.

2.4 Alternative Mitigation
In addition to buffer restoration on subject streams, per the Consolidated Buffer Mitigation Rules (15A
NCAC 02B 0.0295 (o)), alternative mitigation is proposed on the Site in the form of buffer restoration on
ephemeral channels and coastal headwater streams, and preservation of forested buffer on subject and
non -subject streams. The proposed project is in compliance with these rules in the following ways:
Buffer Mitigation on Ephemeral Channels 15A NCAC 02B .0295 (n):
• The ephemeral channel is directly connected to
intermittent or perennial stream channels and will
be protected under the same contiguous easement
boundary (Figure 2).
• The area of the mitigation site on ephemeral
channels does not compromise more than 25
percent of the total area of buffer mitigation.
• The mitigation area on the Site's ephemeral
channels is located completely within its drainage
area.
• The proposed area meets all applicable
requirements of Paragraph (n) of (15A NCAC 02B .0295), for restoration or enhancement.
Buffer Mitigation on Coastal Headwater Streams 15A NCAC 02B .0295 (o)(2):

2.5 Watershed Characterization
The Site topography, as indicated on the Four Oaks, NC USGS 7.5-minute topographic quadrangle shows
a series of moderately sloped valleys (1-3%) that increase in width as they approach the floodplains of
Sassarixa Creek and Black Creek (Figure 3).
Drainage areas for the streams and riparian areas were determined by delineating watersheds on the
Four Oaks USGS 7.5-minute topographic quadrangles. Figure 4 shows the watershed boundaries for
each area. Each of the riparian watersheds are mix of active pastures, fields, and woodlands. The
watershed and current land use are summarized in Table 3 below.

*Proposing stream restoration to reconnect T5A stream throughout. If stream restoration is approved by the IRT and a stream
channel is constructed, then the new riparian areas will be viable as an Enhancement Site per 15A NCAC 028.0295 (a) (6).
2.6 Vegetation
Three reaches on site lack a riparian buffer: T1-RI, the upstream end of T2, and the upstream end of T3.
The riparian buffer in these areas consist primarily of fescue (Festuca sp.) and some areas of hay
production to feed livestock. The canopy on T1-R2 is unique in that it is dominated by loblolly pine
(Pinus taeda) with an understory of Japanese stiltgrass (Microstegium vimeneum). All other riparian
areas include a mix of canopy species including red maple (Acer rubrum), sweetgum (Liquidambar
straciflua), willow oak (Quercus phellos), tulip poplar (Liriodendron tulipifera), ironwood (Carpinus
caroliniana), sycamore (Platanus occidentalis), water oak (Quercus nigra), and black willow (Salix nigra).
While the understory of all reaches is dominated by Japanese stiltgrass, there is still a diverse mix of
understory species present, especially along Sassarixa Creek and T4-R3. Understory species include
Christmas fern (Polystichum acrostichoides), dogfennel (Eupatorium caplilifolium), greenbrier (Smilax
sp.), Virginia creeper (Parthenocissus quinuefolia), sawtooth blackberry (Rubus argutus), common
ragweed (Ambrosia artemisifolia), poison ivy (Toxicodendron radicans), common rush (Juncus effesus),
and common sedge (Carex sp.). Invasive species located in the riparian buffers include Chinese privet
(Ligustrum sinese) and Japanese honeysuckle (Lonicera japonica).
2.7 Site Constraints and Access
The Site is accessible in multiple locations off Old Olive Road. Several culverts and two ford crossing will
be constructed on project streams to allow for continued use of the land outside of the project area for
agriculture. Each crossing is a 35-foot crossing internal to the easement. Wherever possible, culverts will
be located at the start or end of the project reach to limit impact on stream pattern, plan, and profile.
There are no known airport facilities within five miles of the project area (Figure 1). There is one utility
easement at the start of T4 and will be used as a ford crossing. There are no other known constraints on
the proposed Site.
2.8 Current Site Resources
On February 9, 2018 (dated May 21, 2018) Ms. Katie Merritt, with DWR, conducted on -site
determinations to review features and land use within the project boundary. In March 2019 Ms. Sam
Dailey, with USACE, determined two additional features, T1B and TIC, within the project boundary as
intermittent channels, resulting in an additional site -viability letter from Ms. Katie Merritt. The resulting
DWR site viability letters and maps confirming the Site as suitable for riparian buffer mitigation is
enclosed in the Appendix. The on -site determination approval letter from NCDWR is also included in the
Appendix.

2.9 Historic Site Resources
A review of historic aerials from 1950 to 2012, located in the appendix, show that onsite streams have
existed in their approximate locations with very little change to riparian area extents since 1950. Two
alterations to the Site visible from historical aerial photography are the addition of the pond on T2
between 1964 and 1973, and the addition of the large pond below T5A, T513, and T5C between 1950 and
1961.

4.1 Threatened and Endangered Species
The NC Natural Heritage Program (NHP) database and the US Fish and Wildlife Service (USFWS)
database were searched for federally listed threatened and endangered plant and animal species in
Johnston County, NC. Five federally listed species, the red -cockaded woodpecker (Picoides borealis),
dwarf wedgemussel (Alasmidonta heterodon), Tar River spinymussel (Parvaspina steinstansana), yellow
lance (Elliptio lanceolate), and Michaux's sumac (Rhus michauxii) are currently listed in Johnston County.

Wildlands requested review and comment from the United States Fish and Wildlife Service on February
5, 2018 in respect to the Sassarixa Swamp Mitigation Site and its potential impacts on threatened or
endangered species. USFWS responded on March 2, 2018 and stated the "proposed action is not likely
to adversely affect any federally listed endangered or threatened species, their formally designated
critical habitat or species currently proposed for listing under the Act". A follow up email was sent to
USFWS on April 6, 2018 regarding the new addition of the yellow lance on April 4, 2018 to Johnston
Sassarixa Swamp Mitigation Site Final Riparian Area Mitigation Plan
DMS ID No. 100040 Page 10 November 2019

County's endangered species list. USFWS responded on April 9, 2018 with no additional objection. All
correspondence with USFWS is include in the approved Categorical Exclusion found in the Sassarixa
Swamp Mitigation Plan.
A pedestrian survey conducted on April 10, 2018, indicated that the Site did not provide suitable habitat
for the red -cockaded woodpecker and yellow lance. The pedestrian survey did indicate that the site
provides suitable habitat for the dwarf wedgemussel, Tar River spinymussel, and Michaux's sumac but
no species were identified on the site. Therefore, due to the absence of the listed species on the site,
the project has been determined by Wildlands to "may affect, but not likely to adversely affect" the
dwarf wedgemussel and Tar River spinymussel, and to have "no effect" on the Michaux's sumac. The
project will have "no effect" on the red -cockaded woodpecker and yellow lance due to the absence of
suitable habitat.
4.2 Cultural Resources and Significant Natural Heritage Areas
The National Historic Preservation Act declares a national policy of historic preservation to protect,
rehabilitate, restore, and reuse districts, sites, buildings, structures, and objects significant in American
architecture, history, archaeology, and culture, and Section 106 mandates that federal agencies take
into account the effect of an undertaking on a property that is included in, or is eligible for inclusion in,
the National Register of Historic Places.
There are no existing structures in the project area. The Site is not located near any sites listed on the
National Register with the State Historic Preservation Office (SHPO). SHPO was contacted February 2,
2018 and had no concerns or comments on the project site. The approved Categorical Exclusion for the
project is in the Sassarixa Swamp Mitigation Plan.
4.3 FEMA Floodplain Compliance
The Site is represented on the Johnston County Flood Insurance Rate Map Panel 1662. Sassarixa Creek
and the downstream portions of T4, T5, and T6 are mapped in Zone AE from the modeled Black Creek,
however no streams on Site are modeled. Areas within the mapping are slated for stream enhancement
and preservation as part of them stream mitigation project and will not require net fill within the
floodplain. Wildlands will coordinate with the Johnston County floodplain administrator to obtain the
appropriate floodplain development permit for the project, if required.
4.4 Other Environmental Issues
An EDR Radius Map Report with Geocheck was ordered for the Site through Environmental Data
Resources, Inc. on January 29, 2018. The target property and the adjacent properties are not listed in
any of the Federal, State, or Tribal environmental databases searched by EDR. There were no known or
potentially hazardous waste sites identified within one mile of the Parcel.

5.0 Implementation Plan
The Wildlands Team proposes to restore high quality ecological function to Sassarixa Creek and 13
unnamed tributaries on the Site. The ecological uplift can be summarized as transforming agriculturally
impacted areas to a protected forested riparian corridor. The project design will ensure that no adverse
impacts to wetlands or existing riparian areas occur. All riparian restoration activities will commence in
concurrence with the stream mitigation activities and not before. Therefore, the mitigation area where
riparian restoration is being performed may be altered slightly depending on the implementation of the
Sassarixa Swamp Stream Mitigation Plan. Planting and fencing will happen in conjunction with the
Sassarixa Swamp Nutrient Offset and Buffer Mitigation Bank Parcel. Figure 7 illustrates the conceptual
design for the Site.
5.1 Parcel Preparation
The current land uses adjacent to the streams proposed for riparian restoration are active agricultural
lands. Areas slated for riparian restoration that are not impacted by the construction of the stream
mitigation project will require little site preparation including select herbicide treatments or limited
mechanical clearing to remove undesirable underbrush or invasive species. Other areas of the easement
will be graded in accordance with the Interagency Review Team (IRT) approved stream mitigation plan.
After the grading for the stream mitigation is complete, the floodplain will be prepared for seeding and
planting by applying stockpiled topsoil to the floodplain between bankfull elevation of the stream and
the grading limits. All haul roads and other areas of compacted soil within the easement boundary will
be ripped prior to planting.
As part of the stream mitigation project, the farm pond and drainpipe that currently impounds water at
the headwaters of T2 will be eliminated and the channel restored. Several field drains were installed
near the area at the top of the pond to direct stream water and field drainage into the pond. Those will
be severed at the edge of buffer to provide diffuse flow into the easement. The earthen dam is
proposed to be removed and a portion of the dam will be used to fill the pond bottom to provide stable
foundation for construction of the new channel. The path of the future channel will be over -excavated,
and fill material from the old dam will be used to stabilize the pond bed for the construction of the bed
and banks of the new channel. Once the dam is removed, the stream restoration will begin near the
upstream extent of the existing impoundment. Below the existing dam the restored channel will follow
the existing valley flowing southwest until it reaches the confluence with Sassarixa Creek. Sheets 1.25-
1.29 from the Sassarixa Swamp Stream Mitigation Plan (SAW# 2018-00432) set depicts the pond
footprint, conservation easement boundary, and new stream alignment, which is included in Appendix 7
of the Sassarixa Swamp Stream Mitigation Plan.
The specifics of the stream restoration project, including breaching the pond on T2 and grading plan, are
included in the Sassarixa Swamp Stream Mitigation Plan. A 401 permit will be required for all stream
restoration work, including work within the pond on T2 and will be obtained before any work in the
waters begins.
5.2 Riparian Area Restoration Activities
The revegetation plan for the riparian mitigation area will include permanent seeding, planting bare root
trees, live stakes, and herbaceous plugs. These revegetation efforts will be coupled with controlling
invasive species population. The specific species composition to be planted was selected based on the
community type, observation of occurrence of species in riparian areas adjacent to the Parcel, and best
professional judgement on species establishment and anticipated site conditions in the early years
following project implementation. Table 8 list woody species that are native to the area and may
Sassarixa Swamp Mitigation Site Final Riparian Area Mitigation Plan
DMS ID No. 100040 Page 14 November 2019

become established in the Site during the duration of the project. Refer to Sheet 3.0 of the Draft Plans
located in Appendix 7 of the Sassarixa Swamp Stream Mitigation Plan for the planting plan.

*These late successional species may naturally colonize but are not expected to reach high -density numbers, height, and/or
vigor after disturbance.
Trees will be planted at a density sufficient to meet the performance standards outlined in the Rule 15A
NCAC 02B .0295 of 260 trees per acre at the end of five years. No one tree species will be greater than
50% of the established stems. An appropriate seed mix will also be applied as necessary to provide
temporary ground cover for soil stabilization and reduction of sediment loss during rain events in
disturbed areas. This will be followed by an appropriate permanent seed mixture. Planting is scheduled
to begin in March 2020.
Vegetation management and herbicide applications may be needed during tree establishment in the
restoration areas to prevent establishment of invasive species that could compete with the planted
native species.
5.3 Riparian Area Enhancement Activities
The revegetation plan for the enhancement areas under NCAC 02B .0295 (n) will include planting
supplemental bare root trees and controlling invasive species growth. The tree species to be planted
are listed in Table 8.
For enhancement areas under NCAC 02B .0295 (o), cattle exclusion, planting isn't anticipated to be
needed except where required in the stream mitigation plan. A seed mix will be applied where cattle
have caused bare soils and cattle will be excluded from the riparian enhancement areas by fencing.
5.4 Riparian Area Preservation Activities
There will be no parcel preparation work done in the riparian preservation areas, as allowed under 15A
NCAC 02B .0295(o). The preservation area will be protected in perpetuity under a conservation
easement.

Final Riparian Area Mitigation Plan
November 2019

6.0 Monitoring Plan
The Site monitoring plan has been developed to ensure that the required performance standards are
met, and project goals and objectives are achieved. The monitoring report shall provide project data
chronology that will facilitate an understanding of project status and trends, ease population of DMS
databases for analysis and research purposes and assist in close-out decision making.
6.1 Monitoring Components
Project monitoring components are listed in more detail in Table 9 and Figure 8.
6.2 Vegetation
Vegetation monitoring quadrants will be installed across the Site to measure the survival of the planted
trees (Figure 8). The first annual monitoring activities will commence at the end of the first growing
season, at least six months after planting has been completed, and will be reassessed annually no earlier
than the Fall of each year. Species composition, density, height, and survival rates will be evaluated on
an annual basis by plot and for the entire site. The number of monitoring quadrants required, and
frequency of monitoring will be based on the DMS monitoring guidance documents. Vegetation
monitoring will follow the CVS-EEP Protocol for Recording Vegetation (2008) or another DMS approved
protocol. Planted stems will be flagged each monitoring year. Reference photographs of the vegetation
plots and Site will be taken during the annual vegetation assessments.
6.3 Overview Photographs
Overview photographs will be taken of the project area once a year to visually document stability for
five years following construction.
6.4 Visual Assessment
Visual assessments will be performed within the Site on a semi-annual basis during the five-year
monitoring period. Problem areas with vegetative health will be noted (e.g. low stem density, vegetation
mortality, invasive species or encroachment).

7.0 Project Success Crita, id
The project success criteria for the Site follows approved performance criteria presented in the guidance
documents outlined in RFP 16-007279 and the Consolidated Buffer Rule (15A NCAC 02B .0295). Annual
monitoring and semi-annual site visits will be conducted to assess the condition of the finished project.
The buffer mitigation project has been assigned specific performance criteria components for
vegetation. Performance criteria will be evaluated throughout the five-year post -construction
monitoring. An outline of the performance criteria components follows.
7.1 Vegetation
The final vegetative success criteria will be the health, survival, height, and density of at least 260 stems
per acre at the end of the fifth year of monitoring, with a minimum of four native hardwood tree or
Sassarixa Swamp Mitigation Site Final Riparian Area Mitigation Plan
DMS ID No. 100040 Page 16 November 2019

shrub species composition and no one species comprises more than 50 percent of stems. Vigor, species
composition, and density will all be assessed. The extent of invasive species coverage will also be
monitored and controlled as necessary throughout the required monitoring period.
7.2 Overview Photographs
Overview photographs will be taken of the project area once a year to visually document stability for
five years following construction.
7.3 Visual Assessments
Visual assessments should support the specific performance standards for each metric as described
above. Visual assessments will be performed within the Site on a semi-annual basis during the five-year
monitoring period. Problem areas with vegetative health will be noted (e.g. low stem density, vegetation
mortality, invasive species or encroachment). Areas of concern will be mapped and photographed
accompanied by a written description in the annual report. Problem areas with be re-evaluated during
each subsequent visual assessment. Should remedial actions be required, recommendations will be
provided in the annual monitoring report.
To ensure compliance with 0295 (0) (6): A visual assessment of the cattle exclusion and preservation
areas within the conservation easement will also be performed each year to confirm:
• No cattle access within the conservation easement area; no encroachment has occurred;
diffuse flow is being maintained in the conservation easement area; and there has not been
any cutting, clearing, filling, grading, or similar activities that would negatively affect the
functioning of the buffer.
• Any issues identified during the visual assessment of the cattle exclusion and preservation
areas will be photographed and mapped as part of the annual monitoring report with
remedial efforts proposed or documented.
7.4 Reporting Performance Criteria
Using the DMS Riparian Buffer and Nutrient Offset Buffer Baseline and Annual Monitoring Report
Template version 2.0 (May 2017), a baseline monitoring document and as -built record drawings of the
project will be developed for the constructed Site. Complete monitoring reports will be prepared in the
fall of each monitoring year and submitted to DMS. Annual monitoring reports will be based on the
above referenced DMS Template (May 2017). The monitoring period will extend five years beyond
completion of construction or until performance criteria have been met. One vegetation plot and
additional visual monitoring for Coastal Headwaters will extend seven years beyond completion of
construction or until performance criteria have been met. Closeout of buffer mitigation credits adjacent
to the Coastal Headwaters will be done at IRT closeout of the stream and wetland mitigation project.
7.5 Maintenance and Contingency Plans
The Wildlands Team will develop necessary adaptive measures or implement appropriate remedial
actions in the event that the Site or a specific component of the Site fails to achieve the success criteria
outlined above. The project -specific monitoring plan developed during the design phase will identify an
appropriate threshold for maintenance intervention based on the monitored items. Any actions
implemented will be designed to achieve the success criteria specified previously and will include a work
schedule and updated monitoring criteria (if applicable).

8.0 Stewardship
8.1 Long Term Stewardship
The Site will be transferred to the North Carolina Department of Environmental Quality (NCDEQ)
Stewardship Program. This party shall serve as conservation easement holder and long-term steward for
the property and will conduct periodic inspection of the site to ensure that restrictions required in the
conservation easement are upheld. The NCDEQ Stewardship Program is developing an endowment
system within the non -reverting, interest -bearing Conservation Lands Conservation Fund Account. The
use of funds from the Endowment Account will be governed by North Carolina General Statue GS 113A-
232(d)(3). Interest gained by the endowment fund may be used for stewardship, monitoring,
stewardship administration, and land transaction costs, if applicable.
8.2 Adaptive Management Plan
Upon completion of Site construction, Wildlands will implement the post -construction monitoring
defined in Section 7. Project maintenance will be performed during the monitoring years to address
minor issues as necessary. If, during annual monitoring it is determined the Site's ability to achieve Site
performance standards are jeopardized, Wildlands will notify the members of DMS/NCDWR and work
with the DMS/NCDWR to develop contingency plans and remedial actions.
The Wildlands Team will develop necessary adaptive measures or implement appropriate remedial
actions if the Site or a specific component of the Site fails to achieve the success criteria outlined above.
The project -specific monitoring plan developed during the design phase will identify an appropriate
threshold for maintenance intervention based on the monitored items. Any actions implemented will be
designed to achieve the success criteria specified previously and will include a work schedule and
updated monitoring criteria (if applicable).

Dear Mr. Hutton,
On February 9, 2018, Katie Merritt, with the Division of Water Resources (DWR), received a request
from Wildlands Engineering, Inc. (WEI) for an onsite mitigation determination near the above -
referenced site (Site). The Site is located in the Neuse River Basin within the 8-digit Hydrologic
Unit Code 03020201. The Site is being proposed as part of a full -delivery stream and riparian
buffer mitigation project for the Division of Mitigation Services (RFP #16-007279). Members of
the Interagency Review Team (IRT) and Division of Mitigation Services were also present
onsite. At your request, on February 23, 2018, Ms. Merritt performed an onsite assessment of
riparian land uses adjacent to streams onsite, which are shown on the attached map labeled "Figure
6A,%
Ms. Merritt's evaluation of the features and their associated mitigation determination for the riparian
areas are provided in the table below. The evaluation was made from Top of Bank (TOB) out to

Dear Ms. Allen,
On February 20, 2019, Katie Merritt, with the Division of Water Resources (DWR), received a
request from you on behalf of Wildlands Engineering, Inc (WEI) to evaluate the potential for riparian
buffer mitigation and nutrient offset on two additional features on the subject site. Features labeled
T I B and TIC on the attached map labeled "Figure 3a Site Map" were evaluated by Sam Dailey with
the US Army Corps of Engineers in March 2019 and these features were determined to be at least
intermittent channels. The Site is also being proposed as part of a full -delivery stream and riparian
buffer mitigation project for the Division of Mitigation Services (RFP #16-007279).
Ms. Merritt's evaluation of the features 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 .0240.

approval prior to conducting any mitigation activities in riparian areas and/or surface waters for
buffer mitigation credit. Pursuant to 15A NCAC 02B .0240, 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 .0240.
This viability assessment will expire on April 3, 2021 or upon the submittal of an As -Built Report to
the DWR, whichever comes first. This letter should be provided in all stream, wetland or buffer
mitigation plans for this Site.

Re: Site Viability for Buffer Mitigation and Nutrient Offset R Buffer- Sassarixa Swamp
Re-evaluation of T4-Reach 3
2-162 Olive Rd, Smithfield, NC
Neuse 03020201 (not in Falls WS)
Dear Ms. Allen,
On April 4, 2018 and May 21, 2018, the Division of Water Resources {DWR} issued a stream/buffer
determination letter and Site Viability letter respectively, for the subject site. On October 15, 2019,
DWR received a stream determination appeal request from Wildlands Engineering, Inc (Wildlands)
requesting that a feature labeled T4-R3 on the subject site be re-evaluated based on a preliminary
Jurisdictional Determination (JD) by the USACE showing the feature to be a perennial stream and
not a linear wetland. In support of this JD, DWR issued a revised stream /buffer determination letter
on October 28, 2019. T4-R3 and its riparian areas are also being proposed as part of a full -delivery
stream and riparian buffer mitigation project for the Division of Mitigation Services (RFP # 15-
007279).
On October 15, 2019, DWR also received a request from Wildlands to re-evaluate the potential for
riparian buffer mitigation and nutrient offset along T4-R3 based on the JD by USACE.
DWR's evaluation of T4-R3 and its 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 .0240. This evaluation replaces the
evaluations made on T4-R3 issued on May 21, 2018.
