those do not appear. Remove from narrative (since they were in previous report) or show on CCPV.
Response: The supplemental planting narrative, describing the effort completed in 2021, was removed from
the report.
2.Label flow gages on CCPV?
Response: Flow gauges have been labeled on Figures 2A-D.
3.Table 2. Show supplemental plant and invasive treatment dates on this table.
Response: Supplemental planting and invasive treatment dates were added to Table 2.
4.Appendix G. can be removed from report. This data was included in previous monitoring report.
Response: There was no mention of Appendix G in the report, nor was an Appendix G submitted with the
draft report.
5.Table 14. Confirm that bankfull events that occurred on this table were systemic.
Response: Bankfull events listed in Table 14 are systemic. Often, physical documentation of bankfull events
occurs on one or several Site tributaries due to time-lapse camera settings and/or the amount of time
between the event and the site visit, but all bankfull events are supported by a site-wide spike in stream
flow gauge data.

Streams
Stream measurements were not performed in year 4 (2022), in accordance with the monitoring
schedule.
A visual assessment indicates that across the Site, all in-stream structures are intact and
functioning as designed and that channel geometry compares favorably with the proposed
conditions outlined in the Detailed Restoration Plan and as constructed. No stream areas of
concern were identified during year 4 (2022) monitoring. Tables for year 3 (2021) data and annual
quantitative assessments are included in Appendix D.
One bankfull event was documented during year 4 (2022) monitoring for a total of 8 bankfull
events to-date during the monitoring period (Table 14, Appendix E).
Channel formation was evident in all site tributaries during year 4 (2022). The UT1 streamflow
gauge malfunctioned twice during MY4 (2022) before being replaced and capturing 89 days of
consecutive flow. The UT2 and UT3 stream gauges captured 61 days and 131 days respectively.
The UT5 upstream and downstream gauges captured 201 and 130 days respectively. UT6 exhibited
118 consecutive days of flow prior to its failure in July. The upstream and downstream gauges on
UT7 both failed resulting in data loss between April and July; however, they captured 36 days and
59 days respectively prior to the failures, and the UT7 middle gauge captured 209 days of flow. The
UT8 gauge also malfunctioned between April and July, but it captured 108 consecutive days of flow
prior to its failure. All stream gauges were replaced with Onset U-20 gauges, and no additional
malfunctions or failures are anticipated. Channel formation tables and graphs are in Appendix E.
Wetlands
Five of six groundwater gauges met success for the Year 4 (2022) monitoring period. Gauge 6
malfunctioned on March 22. It was relaunched on April 20; however, it failed immediately after
relaunch which resulted in the loss of data during this time-period. Based on precipitation data and
groundwater data from nearby gauges 4 and 5, it is expected that gauge 6 would have met success
criteria during the time of the malfunction. All gauges were replaced with new Onset U-20 gauges
on July 29, and no further gauge failures are anticipated. Wetland hydrology data are in Appendix
E.

replaced with new Onset U-20 gauges on 7/29/22.
Vegetation Summary
In accordance with the monitoring schedule, vegetation plot monitoring was not performed in Year
4 (2022); however, 6 temporary vegetation plots were catalogued yielding an average stem density
of 486 stems per acre. Additionally, each individual plot met MY3 success criteria. Temporary plot
data is in Table 8 (Appendix C). Visual assessment indicates that vegetation on the Site is vigorous.

1.0 PROJECT SUMMARY
Restoration Systems, LLC has established the North Carolina Division of Mitigation Services (NCDMS)
Heron Stream and Wetland Restoration Site (Site).
1.1 Project Goals & Objectives
Project goals were based on the Cape Fear River Basin Restoration Priorities (RBRP) report (NCEEP 2009)
and on-site preconstruction data collection of channel morphology and function observed during field
investigations. The Site is located within Targeted Local Watershed (TLW) 03030002050050. The RBRP
report documents benthic ratings vary between “Fair” and “Good-Fair” possibly due to cattle, dairy, and
poultry operations. The project is not located in a Regional or Local Watershed Planning Area; however,
RBRP goals addressed by project activities are as follows with Site specific information following the RBRP
goals in parenthesis.
1.Reduce and control sediment inputs (sediment input reduction of 67.3 tons/year);
2.Reduce and manage nutrient inputs (livestock removed from streams, elimination of fertilizer
application, installation of marsh treatment areas; and a direct reduction of 893.2 pounds of
nitrogen and 47.0 pounds of phosphorus per year);
Site specific mitigation goals and objectives were developed through the use of North Carolina Stream
Assessment Method (NC SAM) and North Carolina Wetland Assessment Method (NC WAM) analyses of
preconstruction and reference stream systems at the Site (NC SFAT 2015 and NC WFAT 2010) (see Table
1).

Composition
1.2 Project Background
The Heron Stream and Wetland Mitigation Site (hereafter referred to as the “Site”) encompasses a 17.64-
acre easement along warm water, unnamed tributaries to Pine Hill Branch and unnamed tributaries to
South Fork Cane Creek. The Site is located approximately 4 miles southeast of Snow Camp and 4.5 miles
north of Silk Hope in southern Alamance County near the Chatham County line (Figure 1, Appendix A).
Prior to construction, Site land use consisted of disturbed forest and agricultural land used for livestock
grazing and hay production. Livestock had unrestricted access to Site streams, which had been cleared,
dredged of cobble substrate, straightened, trampled by livestock, eroded vertically and laterally, and
received extensive sediment and nutrient inputs from stream banks and adjacent pastures.
Approximately 62 percent of the stream channel had been degraded contributing to sediment export from
the Site resulting from mechanical processes such as livestock hoof shear. In addition, streamside
wetlands were cleared and drained by channel downcutting and land uses. Preconstruction Site
conditions resulted in degraded water quality, a loss of aquatic habitat, reduced nutrient and sediment
retention, and unstable channel characteristics (loss of horizontal flow vectors that maintain pools and an
increase in erosive forces to channel bed and banks). Site restoration activities restored riffle-pool
morphology, aided in energy dissipation, increased aquatic habitat, stabilized channel banks, and greatly
reduced sediment loss from channel banks.
1.3 Project Components and Structure
Proposed Site restoration activities generated 5293 Stream Mitigation Units (SMUs) and 0.66 Wetland
Mitigation Units (WMUs) as the result of the following.
4068 linear feet of Priority I stream restoration
1184 linear feet of stream enhancement (Level I)
1090 linear feet of stream enhancement (Level II)
0.35 acre of riparian wetland restoration
0.61 acre of riparian wetland enhancement
MY4 (2022) Monitoring Report (Project No. 100014) page 3
Heron Stream and Wetland Mitigation Site Restoration Systems, LLC
Alamance County, North Carolina February 2023
Additional activities that occurred at the Site included the following.
Installation of six marsh treatment areas throughout the Site.
Fencing the entire conservation easement by leaving some pre-existing fencing, removing fencing,
and installing additional fencing.
Planting 12.05 acres of the Site with 15,625 stems (planted species and densities by zone are
included in Table 7 \[Appendix C\]).
Deviations from the construction plans included realignment of UT 1B (adding 20 linear feet to the
alignment) due to conflicts with a gas line crossing. The realignment resulted in the reduction of a log
vane and alterations to pipe configurations within the crossing. Gas line realignment also affected the
length of UT 2 in its lower reaches (shortening the Restoration reach). UT 2 also has minor deviations in
the enhancement II reach due to profile elevation alterations to tie to the invert of UT 1B. These profile
alterations were included in construction plans, but not included in table updates of the detailed plan.
Profile alterations resulted in the Enhancement (level II)/Restoration initiation point migrating upstream,
and thus the length of the Enhancement (Level II) reach (UT 2A) decreased by 39 feet, and the length of
the restoration reach (UT 2B) increased by 17 feet.
Minor easement deviations after construction plan development resulted in some stationing changes,
most notable at the upper reaches of UT 1A (adding 5 linear feet to the alignment) and UT 8A & UT 8B
(reducing the alignments by a total of 4 linear feet). The easement variations also affected channel lengths
across gas lines, which do not generate mitigation credit. Eight log cross-vanes were not constructed due
to contact with bed rock, or conflicts with the gas line. In addition, a marsh treatment area was added to
the right bank of UT 6 at a draw that was concentrating surface drainage and scouring the valley walls.
No other deviations of significance occurred between construction plans and the as-built condition. In
addition, no issues have arisen since construction occurred.
Site design was completed in July 2018. Construction started on November 27, 2018 and ended within a
final walkthrough on February 11, 2019. The Site was planted on February 21, 2019. Completed project
activities, reporting history, completion dates, project contacts, and background information are
summarized in Tables 1-4 (Appendix A).
1.4 Success Criteria
Project success criteria have been established per the October 24, 2016 NC Interagency Review Team
Wilmington District Stream and Wetland Compensatory Mitigation Update. Monitoring and success
criteria relate to project goals and objectives. From a mitigation perspective, several of the goals and
objectives are assumed to be functionally elevated by restoration activities without direct measurement.
Other goals and objectives will be considered successful upon achieving success criteria. The following
table summarizes Site success criteria.
Space Purposefully Left Blank
MY4 (2022) Monitoring Report (Project No. 100014) page 4
Heron Stream and Wetland Mitigation Site Restoration Systems, LLC
Alamance County, North Carolina February 2023
Success Criteria
Streams
All streams must maintain an Ordinary High-Water Mark (OHWM), per RGL 05-05.
Continuous surface flow must be documented each year for at least 30 consecutive days. Surface water
monitoring gauges will be installed in the upper third of all intermittent channels, unless otherwise requested
by the IRT.
Bank height ratio (BHR) cannot exceed 1.2 at any measured cross-section.
Entrenchment ratio (ER) must be no less than 2.2 for E- and C-type channels at any measured riffle cross-
section. Note: B-type channels may have an ER less than 1.4.
BHR and ER at any measure riffle cross-section should not change by more than 10% from baseline condition
during any given monitoring period.
The stream project shall remain stable and all other performance standards shall be met through four separate
bankfull events, occurring in separate years, during the monitoring years 1-7.
Wetland Hydrology
Saturation or inundation within the upper 12 inches of the soil surface for, at a minimum, 10 percent of the
growing season, during average climatic conditions. Note: Soil temperature for growing season establishment
will be measured daily utilizing a continuous monitoring soil probe. Soil temperature will be measured from
mid-February through the end of April (at a minimum).
Vegetation
Within planted portions of the site, a minimum of 320 stems per acre must be present at year 3; a minimum
of 260 stems per acre must be present at year 5; and a minimum of 210 stems per acre must be present at
year 7.
Trees must average 7 feet in height at year 5, and 10 feet in height at year 7 in each plot.
Planted and volunteer stems are counted, provided they are included in the approved planting list for the site;
natural recruits not on the planting list may be considered by the IRT on a case-by-case basis.
2.0 METHODS
Monitoring requirements and success criteria outlined in this plan follow the October 24, 2016 NC

Stream Summary
Stream measurements were not performed in year 4 (2022), in accordance with the monitoring schedule.
A visual assessment indicates that across the Site, all in-stream structures are intact and functioning as
designed and that channel geometry compares favorably with the proposed conditions outlined in the
Detailed Restoration Plan and as constructed. No stream areas of concern were identified during year 4
(2022) monitoring. Tables for year 3 (2021) data and annual quantitative assessments are included in
Appendix C.
One bankfull event was documented during year 4 (2022) monitoring for a total of 8 bankfull events to-
date during the monitoring period (Table 14, Appendix E).
Channel formation was evident in all site tributaries during year 4 (2022). The UT1 streamflow gauge
malfunctioned twice during MY4 (2022). After it was replaced in July, it captured 89 days of consecutive
flow. The UT2 and UT3 stream gauges captured 61 days and 131 days respectively. The UT5 upstream and
downstream gauges captured 201 and 130 days respectively. UT6 exhibited 118 consecutive days of flow
prior to its failure in July. The upstream and downstream gauges on UT7 both failed resulting in data loss
between April and July; however, they captured 36 days and 59 days respectively prior to the failures. The
UT7 middle gauge captured 209 days of flow. The UT8 gauge also malfunctioned between April and July,
but it captured 108 consecutive days of flow prior to its failure. All stream gauges were replaced with
Onset U-20 gauges in July, and no additional malfunctions or failures are anticipated. Channel formation
tables and graphs are in Appendix E.

Five of six groundwater gauges met success for the Year 4 (2022) monitoring period. Gauge 6
malfunctioned on March 22. It was relaunched on April 20; however, it failed immediately after relaunch
which resulted in the loss of data during this time-period. Based on precipitation data and groundwater
data from nearby gauges 4 and 5, it is expected that gauge 6 would have met success criteria during the
time of the malfunction. All gauges were replaced with new Onset U-20 gauges on July 22, and no further
gauge failures are anticipated. Wetland hydrology data are in Appendix E.
Vegetation Summary
In accordance with the monitoring schedule, vegetation plot monitoring was not performed in Year 4
(2022); however, 6 temporary vegetation plots were catalogued yielding an average stem density of 486
stems per acre. Additionally, each individual plot met MY3 success criteria. Temporary plot data is in Table
8 (Appendix C). Visual assessment indicates that vegetation on the Site is vigorous.
Supplemental planting of 3.87 acres was conducted in 2021 in previously identified areas of poor growth
rates or vigor using 1,290 plants to improve the Site’s overall stem density. These areas are identified on
Figures 2A, 2B, and 2C (Appendix B) and are outside vegetation plots. Planting occurred at a rate of
approximately 330 bare root stems per acre of the following species: river birch (Betula nigra), green ash
(Fraxinus pennsylvanica), tulip poplar (Liriodendron tulipifera), red bud (Cercis canadensis), sycamore
(Platanus occidentalis), white oak (Quercus alba), water oak (Quercus nigra), willow oak (Quercus phellos),
and red oak (Quercus rubra).
