Mill Run Development Group, LLC
Dear Emily:
On behalf of Mill Run Development Group, LLC, we are providing a copy of the Year 4 monitoring
report for the Mussel Run Restoration Project. As you know, this project was implemented as site
specific mitigation for the Cutter Creek Development outside of Kinston. On -site construction was
completed in April 2008. An average of 1106 stems /acre (planted and volunteer) were observed during
the Year 4 monitoring event, indicating that the site is progressing well toward the target community.
Successful restoration of wetland hydrology throughout the site has also been achieved.
Ms. Amy Adams informed us recently that neither the ACOE nor DWQ received the Year 3 monitoring
report. Enclosed is that report as well.
Please contact me if you have any questions. Thank you for your assistance with this project.
Sincerely,
VL_�

Mussel Run Headwater Restoration Project
Site Specific Mitigation for Cutter Creek (Greene County, NC)
Annual Monitoring Report —Year 4
Introduction
Construction of the Mussel Run Headwater Restoration Project, the off -site mitigation project for
the Cutter Creek development, was completed on April 18, 2008. This project, totaling 26.4 acres,
was designed to provide mitigation for buffer and stream impacts associated with the construction
of Lake Nina within the Cutter Creek development. The mitigation project is located off of
Ormondsville Road near the town of Fourway, NC approximately five miles from the impact area
(Figures 1 -4).
This project was reviewed and approved by regulatory staff and the proper permits were obtained
(Action ID# SAW - 2007 -02828; DWQ Project# 07- 0156). Following initial construction, the site will
be monitored for a period of five years. Success will be based on demonstration of appropriate
survivorship and hydrology consistent with wetlands in this landscape position. Following each
monitoring event, a report documenting these aspects will be submitted to regulatory staff.
II. On-site Construction
The first phase of construction involved the removal of the existing road bed, Material from this
road bed was used to fill in two irrigation ponds, totaling 1.2 acres. Finished grades within these
ponds provide a gradual decrease in elevation from the surrounding fields. The second phase
involved the filling of approximately 1,100 linear feet of drainage ditch and removal of a large road
bed present throughout the site. In areas where ditch filling was not appropriate due to hydrologic
trespass concerns, grading was conducted to reduce the amount of channel incision.
The third phase involved the construction of a new 600' channel to provide drainage from the
eastern pond (Pond 1). Grading in this area was configured to mimic a natural "riffle- pool"
sequence found in Coastal Plain streams. A slope of 0.002 was maintained throughout this
portion, The fourth phase involved the construction of a 150' channel to provide drainage from the
western pond (Pond 2) into the existing ditch adjacent to Mussel Run. Similar slopes were
maintained for this section. The final phase involved grading and fill work along the northern
portions of the existing stream /ditch network. Grading this area was configured to direct drainage
from the existing fields into Pond 2 and the restored channels (Figure 5).
III. Site Planting
Prior to planting, the entire project area was disked to enhance microtopography and reduce soil
compaction. Following the disking, 16,000 bare -root seedlings were planted throughout the 26.4
acre project area. Each seedling was planted on 8' centers, with an average density of 600 stems
per acre. A total of six species were planted in one of three different zones: Neuse Buffer,
Cypress -Gum Pond, and Coastal Plain Headwater wetland (Table 1). These zones will correspond
to a frequency of inundation and elevation relative to the reestablished stream channels. A
wetland seed mix was also applied to minimize erosion during the first growing season.

IV. Monitoring Equipment Installation
A total of six 0.10 -acre permanent monitoring plots, representing 2% of the project area, were
established (Figure 6). These plots were randomly spaced throughout each of the three main
restoration zones. The vegetative success criterion for these areas is survivorship totals that meet
or exceed 320 woody stems per acre at the end of the five year monitoring period. Hydrology
within the site is being monitored using shallow groundwater monitoring wells. A total of three 40-
inch wells were installed throughout the project area. Each well records the static water depth on a
daily basis. Well data and rainfall data (obtained from the Kinston airport) are graphically depicted
in Appendix C. In order to meet the appropriate success criteria, these areas must demonstrate a
water table within 12 inches of the soil surface for a minimum of 12 consecutive days (equal to or
greater than 5% of the growing season).
V. Annual Monitoring
Year 4 annual monitoring was conducted in October 2011. A total of 664 woody stems were
counted throughout the six monitoring plots, corresponding to an average of 1106 stems per acre
for the project area (Table 2). Of the 664 stems, 400 stems were of planted species,
corresponding to an average of 667 stems per acre. As in previous years, river birch (Betula nigra)
seedlings were the most abundant planted species. In 2011, 287 individuals were observed within
the plots. This is an increase from 180 individuals observed in 2010 and shows that this species is
volunteering throughout the site. Bald cypress (Taxodium distichum) was the second most
abundant species, with 85 individuals observed (Appendix A). This is a slight decrease from the 90
individuals observed in 2010. Overall, vigorous growth was observed throughout the site (see
Appendix 8 for site photographs).
Hydrologic monitoring was initiated in May 2008 with the installation of three WM -40 groundwater
monitoring wells. Data collected during 2011 documented periods of saturation and surface
ponding throughout the site during the early growing season despite below normal antecedent
rainfall totals. While these below normal rainfall totals persisted for a couple of months, each of
three wells exceeded the minimum success for the fourth year of monitoring (Table 3).

Table 3. Summary of Hydrologic Monitoring Data -- Year 4
Based on the observed hydroperiods, the site has responded favorably to the prescribed
hydrologic modifications. These modifications have resulted in extended periods of surface
ponding and saturation during the early growing season, which is typical of headwater systems in
the Coastal Plain. As a result, the nutrient and sediment removal functions within the wetland have
been restored, improving water quality and reducing downstream flooding. Appendix C provides
specific data collected during 2011.

VI. Conclusion
Restoration activities have been demonstrated to be successful at the project site through the four
years of annual monitoring. The observed density (1106 stems/acre) indicates that planted
individuals are doing well and desirable species of native vegetation from adjacent areas are
volunteering in the site. The site is greatly surpassing the vegetative success criterion of a maturity
density of 320 stems/acre. The 2011 hydrologic monitoring data met the hydrologic success
criteria despite a few months of below normal precipitation levels.
Reversion of agricuitural land to wooded riparian buffer and wetland habitat will decrease source
nutrient loading and concurrently increase nutrient removal capacity. In addition, the project will
provide ancillary benefits to aquatic and wildlife habitat via enhanced niche habitat, microclimate
modification and shade, and increased food -web support. By doing so, the proposed project is
helping to effectively mitigate for authorized loss of riparian buffers, streams and wetlands
associated with the Cutter Creek development.

Mussel Run Headwater Restoration Project
Site Specific Mitigation for Cutter Creek (Greene County, NC)
Annual Monitoring Report — Year 3
I. Introduction
Construction of the Mussel Run Headwater Restoration Project, the off -site mitigation project for
the Cutter Creek development, was completed on April 18, 2008. This project, totaling 26.4 acres,
was designed to provide mitigation for buffer and stream impacts associated with the construction
of Lake Nina within the Cutter Creek development. The mitigation project is located off of
Ormondsville Road near the town of Fourway, NC approximately five miles from the impact area
(Figures 1 -4).
This project was reviewed and approved by regulatory staff and the proper permits were obtained
(Action ID# SAW -2007 -02828; DWO Project# 07- 0156). Fallowing initial construction, the site will
be monitored for a period of five years. Success will be based on demonstration of appropriate
survivorship and hydrology consistent with wetlands in this landscape position. Following each
monitoring event, a report documenting these aspects will be submitted to regulatory staff.
II. On -site Construction
The first phase of construction involved the removal of the existing road bed. Material from this
road bed was used to fill in two irrigation ponds, totaling 1.2 acres. Finished grades within these
ponds provide a gradual decrease in elevation from the surrounding fields. The second phase
involved the filling of approximately 1,100 linear feet of drainage ditch and removal of a large road
bed present throughout the site. In areas where ditch filling was not appropriate due to hydrologic
trespass concerns, grading was conducted to reduce the amount of channel incision.
The third phase involved the construction of a new 600' channel to provide drainage from the
eastern pond (Pond 1). Grading in this area was configured to mimic a natural "riffle- pool"
sequence found in Coastal Plain streams. A slope of 0.002 was maintained throughout this
portion. The fourth phase involved the construction of a 150' channel to provide drainage from the
western pond (Pond 2) into the existing ditch adjacent to Mussel Run, Similar slopes were
maintained for this section. The final phase involved grading and fill work along the northern
portions of the existing stream /ditch network. Grading this area was configured to direct drainage
from the existing fields into Pond 2 and the restored channels (Figure 5).
111. Site Planting
Prior to planting, the entire project area was disked to enhance microtopography and reduce soil
compaction. Following the disking, a five man crew was dispatched to plant 16,000 seedlings
throughout the 26.4 acre project area. Each seedling was planted on &' centers, with an average
density of 600 stems per acre. A total of six species were planted in one of three different zones,
Neuse Buffer, Cypress -Gum Pond, and Coastal Plain Headwater wetland (Table 1). These zones
will correspond to a frequency of inundation and elevation relative to the reestablished stream
channels. A wetland seed mix was also applied to minimize erosion during the first growing
season.

IV. Monitoring Equipment Installation
A total of six 0.10 -acre permanent monitoring plots, representing 2% of the project area, were
established (Figure 6). These plots were randomly spaced throughout each of the three main
restoration zones. The success criteria for these areas will be based on survivorship totals which
meet or exceed 320 woody stems per acre at the end of the five year monitoring period. Hydrology
within the site will be monitored using shallow groundwater monitoring wells. A total of three 40-
inch wells were installed throughout the project area. Each well records the static water depth on a
daily basis. Well data will then be graphed in addition to rainfall totals from the Kinston airport and
is presented in Appendix C. In order to meet the appropriate success criteria, these areas must
demonstrate a water table within 12 inches of the soil surface for a minimum of 12 consecutive
days equal to or greater than 5% of the growing season.
V. Annual Monitoring
Year 3 annual monitoring was conducted in September 2010. A total of 522 woody stems were
enumerated throughout the six monitoring plots, corresponding to an average of 870 stems per
acre for the project area (Table 2), Of the planted species, river birch (Befula nigra) seedlings were
the most abundant, totaling 180 individuals throughout the plots. Bald cypress (Taxodium
disfichum) was the second most abundant species, with 90 individuals observed (Appendix A).
Overall, vigorous growth was observed throughout the site despite abnormally dry to moderate
drought conditions throughout the summer months (see Appendix B for site photographs).
Hydrologic monitoring was initiated in May 2008 with the installation of three WM -40 groundwater
monitoring wells. Data collected during 2010 documented periods of saturation and surface
ponding throughout the site during the early growing season despite below normal antecedent
rainfall totals. While these below normal rainfall totals persisted for a couple of months, each of
three wells exceeded the minimum success for the third year of monitoring (Table 3).

Table 3. Summary of Hydrologic Monitoring Data — Year 3
Based on the observed hydroperiods, the site has responded favorably to the prescribed
hydrologic modifications. These modifications have resulted in extended periods of surface
ponding and saturation during the early growing season, which is typical of headwater systems in
the Coastal Plain. As a result, the nutrient and sediment removal functions within the wetland have
been restored, improving water quality and reducing downstream flooding. Appendix C provides
specific data collected during 2010.

VI. Conclusion
Restoration activities have been demonstrated to be successful at the project site through the two
years of annual monitoring. The observed density (870 stems/acre) indicates that the site is
surpassing a maturity density of 320 stems/acre. The 2010 hydrologic monitoring data met the
hydrologic success criteria despite a few months of below normal precipitation levels. It is
anticipated that normal rainfall conditions throughout the winter and early spring will continue to
restore appropriate hydrologic conditions throughout the headwater wetland system.
Reversion of agricultural land to wooded riparian buffer and wetland habitat will decrease source
nutrient loading and concurrently increase nutrient removal capacity. In addition, the project will
provide ancillary benefits to aquatic and wildlife habitat via enhanced niche habitat, microclimate
modification and shade, and increased food -web support. By doing so, the proposed project will
help to effectively mitigate for authorized loss of riparian buffers, streams and wetlands associated
with the Cutter Creek development.
