Re: Cool Run Response to DMS Comments on MY1 Report

USACE Action ID No. SAW-2020-01428, DWR Project No. 20200712
Dear Mr. Dow,
Please find below the response to comments on the Cool Run Mitigation Plan provided by DMS
dated February 2, 2024:
1. Section 1.2 Success Criteria footnote says that for Year 1, the success criteria will be
measured from March 1 to Nov. 30th, but also states that hydrologic improvements were not
completed until April 6 and hydrograph data does not start until April 25. Please clarify. Is your
MY1 success based on the consecutive days you would have needed if hydrology were being
collected at March 1, even though data collection doesn’t start until April 25 (this is fine, just
looking for clarification)?
Re: Section 1.2 success criteria was clarified by distinguishing monitoring periods for
Year 1 and remainder of monitoring period. Data collection dates for hydrology and
vegetation monitoring were also distinguished for MY1. MY1 success is based on the
portion of the growing season beginning with normal rainfall conditions after gauge
installation, May 5 through November 30 (or 210 days). Vegetation for MY1 was
monitored in the fall of 2023 and planted on April 6. MY2 hydrology will be monitored
from February 1 through November 30.
2. Section 2.0 – says record drawings are included. Please remove any reference to inclusion of
Record Drawings and please remove the record drawings (Appendix F) from this report and all
future monitoring reports.
Re: Record drawings have been removed from the report in addition to any text referencing
the drawings.
3. Please remove Section 3.1. An entire section with one sentence saying see Table 4 is
unnecessary.
Re: Section 3.1 has been removed.
4. Section 3.0 – remove reference to Section 3.1.
Re: Statement referencing 3.1 has been removed.

5. Section 4.0 – Says monitoring methods are detailed in Section 3.0, but there are no methods
discussed in Section 3.0. Refer to Table 4 here.
Re: Section 3.0 now references Table 4 for monitoring parameters. In addition, Section 4.0
also references Table 4.
6. Table 5 – Doesn’t need the last 3 columns nor the 5% wetland criteria column. Simply report
whether the gauges met the success criteria as proposed in the approved mitigation plan. Please
color code the cells or text green/red to indicate meeting or not meeting in the 12% Success
Criteria column for quick reference. Keep in mind that this Table will need to summarize
attainment of success criteria for all years as monitoring progresses so overall trends can be easily
observed by reviewers. Please use a version of this Table such as the example in the DMS
template, or I am happy to provide other examples.
Re: Table 5 has been edited to include only the percentage for MY1 success criteria. Cells
have been color coded to ease the interpretation of success criteria. In subsequent reports
we will continue to include corresponding year’s hydrology analysis to the table .
7. Section 4.2.2 – states that S2 maintained flow for the entire monitoring period and S1
maintained flow for the majority. Please reference the streams when discussing gauges, i.e.,
“Cool Run (S1) maintained flow…” Please state the actual number of consecutive days of flow
instead of simply saying majority. Include a table summarizing flow that can be updated each
year (can be in an Appendix). This table only needs to show the gauges with a flow requirement
and the number of consecutive days of flow each monitoring year.
Re: Section 4.2.2 now clearly identifies streams with the addition of “Cool Run” or “UT1”
when referencing stream gauges. These labels have also been included in Table 6. When
stating consecutive days of flow actual numbers are mentioned rather than adjectives such
as majority. An additional table, “Table 7. Summary of Year 1 Stream Flow”, was added to
summarize the stream flow data in a tabular format. Additional years will be added as
monitoring continues.
8. Section 4.3 – may want to add statement about ongoing sweet gum thinning that started in
MY1. Was there any other invasive management following as-built?
Re: Sweet gum thinning efforts, herbicide applications, and additional hack and squirt
applications were further described in Section 4.3.
9. Section 4.4 – Please add a sentence here stating that whatever the final growing season is
determined to be in MY2, that those dates will be held constant for the remainder of monitoring.
Re: In Section 4.4, MY1 growing season was described. A statement clarifying that when a
growing season is agreed upon, those dates will remain the standard throughout the site’s
monitoring was added.

10. Section 4.5 – Sentence reads “Stream flow as documented throughout the majority of the
year.” Please correct.
Re: The statement was corrected to read “Stream flow was present in Cool Run for 190
days and UT1 for 219 days.”
11. Figure 1
a. S1 is not labeled.
b. Please include the streams in the Legend with associated credit ratios.
c. Plot 11 is in planting Zone 1, but is color coded like a Zone 2 plot that had less than 324
stems per acre. More distinct symbology differentiating between plots in each planting Zone
is recommended.
Re: S1 has been labeled. Streams have been included in the legend along with their
associated credit ratios. A table in the top right corner of the figure also displays
footage/acreage and associated credits. Plot 11 symbology was altered to reflect its
correct planting zone, Zone 1. Symbology for Planting Zone 1 remains a square.
Symbology for Zone 2 was changed to a pentagon. Green reflects successful permanent
plots while orange reflects permanent plots that did not meet the success criteria. Blue
symbolizes random plots.
12. During the MY0 site visit it was requested that random veg plots be placed in rehab areas
without veg plots and P2 areas. This was not done in MY1. Please place random plots in
these areas in MY2.
Re: A note was placed within our system to ensure random veg plots are placed within
rehab areas for MY2.
13. Appendix A – is documenting evidence of senescence with trees along a four lane highway
an appropriate location? Generally, these trees are more stressed due to herbicides in the soil
from roadside treatments among other potential stressors.
Re: Photos documenting senescence displaying a four-lane highway are not an exact
representation of the mitigation site. But they do represent a general depiction of
Brunswick County. A four-lane highway does pose additional stressors that would not
be present within a mitigation site. But one could assume that if trees within this area
are exposed to additional stressors and display incomplete abscission, trees in an
environment lacking those stressors would retain their leaves for a longer period as they
have a higher quality environment.
14. Appendix C
a. Recommend removing BHR calculations on pool cross sections.
b. Please ensure cross section graphs have lines for both Bankfull Elevation Based on MY0
Cross Sectional Area and current LTOB (which is what I believe is currently shown on the
graph)
Clearwater Mitigation Solutions
604 Macon Place, Raleigh, NC 27609
919-624-6901
clearwatermitigation@gmail.com
c. It is observed that virtually all cross sections have identical elevations for “Bankfull
Elevation (ft) ‐ Based on As Built‐Bankfull Area” and “Low Top of Bank Elevation.”
With the obvious aggradation and change in cross sectional area, these numbers would not be
identical and BHRs would not all be 1.00. We would expect many, or most, of the BHRs to
be <1 (ex. 0.92, 0.80, etc.). Please recalculate “Bankfull Elevation (ft) ‐ Based on As
Built‐Bankfull Area” and BHRs correctly. Please visit the following link for further
guidance or reach out to discuss. https://www.deq.nc.gov/mitigation-services/document-
management-library/guidance-and-template-documents/monitoring-channel-change-dms-
mitigation-projects/open
d. While XS-2 displays obvious aggradation, is it accurate that it lost approx. 2/3 of its cross-
sectional area?
Re: Bank height ratios for pool cross sections have been removed. Lines representing
bankfull elevations based on MY0 Cross Sectional Area and Current LTOB is now
displayed on cross sectional graphs. Bank height ratios have been recalculated for all
riffles. Values now reflect the correct BHRs and are less than 1.00. Based on the revised
cross-sections, XS-2 has lost approximately 40% of its cross-sectional area.
15. GW Gauge hydrographs – showing 3 gauges on each graph can be confusing. Would
recommend trying to fit each year’s graph onto one page and include only one gauge per
graph. Indicate which gauge, or gauges, are being shown in the title at the top of each page. It
is also useful to call out on the graph where the longest period of consecutive days of meeting
success is located, with the number of days and percent of growing season displayed.
Re: Your recommendation was applied and hydrographs now reflect a singular gauge
per graph along with an entire monitoring period. The title along with the legend
displays the respective gauge with the longest period of consecutive days meeting
success criteria called out. Next to the call out, in the legend, the number of days and
percent of growing season is listed.
16. On the stream gauge hydrographs, please indicate clearly which project stream is associated
with each gauge.
Re: Stream gauge hydrographs now clearly indicate which project stream they are
associated with.
17. What is the purpose of the stream gauge graphs that only show April 30 th, Aug. 3 – 5, July 6,
etc.? Overbank events can be seen (and if difficult to see, called out) on the condensed graphs
that show a larger portion of the year. A better use of space would be to have a separate graph
for each stream gauge.

Re: Stream gauge graphs that depict only a specific range of dates represent overbank
events. More specifically, these graphs depict hourly stream data rather than daily
stream data depicted at a consistent time of 7:00 AM. When condensing hourly stream
data to a singular period, overbank events can be eliminated if an event occurred for
less than 24 hours. In this case, if hourly periods were not called out, the event that
occurred on April 30th would not be noticed. Daily stream data during this period shows
both S1 and UT1 do not reach the top of bank if only interpreting data at 7:00 AM. In
addition, if an annual hourly graph was displayed, the data depicted would be rather
confusing to interpret. Hourly data is selected only for periods where overbank events
occurred to minimize data displayed and ease interpretation.
Please do not hesitate to contact me with questions at 919-624-6901.

Cool Run Mitigation Site Clearwater Mitigation Solutions
Brunswick County, North Carolina February 2024
1.0 PROJECT SUMMARY
Clearwater Mitigation Services has established the North Carolina Division of Mitigation Services
(NCDMS) Cool Run Stream & Wetland Mitigation Site (hereafter referred to as the “Site”). The
Site encompasses 25.6 acres of floodplain forest and agricultural fields along Cool Run and an
Unnamed Tributary (UT) to Cool Run located within the Carolina Flatwoods of the Middle Atlantic
Coastal Plain Ecoregion (63h). The Site is located within a Targeted Local Watershed of the Upper
Shallotte River 14-digit HUC (03040207020060) of the Lumber River basin. Stream and wetland
mitigation areas are located along Cool Run and a UT to Cool Run within North Carolina Division
of Water Resources [NCDWR] subbasin number 03-07-59. Site watersheds range from
approximately 3.10 square miles (1,985 acres) along Cool Run to approximately 0.2 of a square
mile (125 acres) along UT1.
1.1 Project Background, Components, and Structure
The site is located in Brunswick County, approximately 5.5-miles West of Shallotte, NC.
Restoration activities within the Site included the construction of meandering, E/C-type stream
channel resulting in 2,024 linear feet of Priority I stream restoration, 603 linear feet of Priority II
stream restoration, 14.108 acres of riparian wetland re-establishment, 1.433 acres of riparian
wetland rehabilitation, 1.201 acre of riparian wetland enhancement, and 0.492 acre of riparian
wetland preservation. The site is expected to provide 2,422.667 warm water stream credits and
15.512 riparian wetland credits by closeout (Table 1). A conservation easement was granted to
the State of North Carolina and recorded at the Brunswick County Register of Deeds on February
12, 2021.
Prior to site construction, the site was characterized by disturbed forest that was previously
utilized for agriculture and silviculture dating back to the 1950’s. Based on historical aerial
photography, Cool Run appears to have been relocated and channelized in the late 1950’s. These
photographs also depict the channelization of UT1 prior to 1956. Historically, logging and
additional modifications have been documented throughout the floodplain for the past several
decades. The most recent logging event occurred between 2016 and 2018. Site design was
completed in June 2022. Construction began in December 2022, and ended with a final
walkthrough on April 19, 2023. The site was planted on April 6, 2023. Completed project
activities, reporting history, completion dates, and project contacts are summarized in Tables 11-
12 (Appendix E).

1.2 Success Criteria
Monitoring and success criteria for stream restoration should relate to project goals and
objectives identified from on-site NC SAM and NC WAM data collection in addition to guidelines
set forth in the 2016 Mitigation Rule. 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 summarizes the site success criteria developed for the project.
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.
• Bank height ratio (BHR) cannot exceed 1.2 at any measured cross-section.
• BHR 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, 12 percent of the
growing season (36 days)*, during normal climatic conditions.
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.
• Any volunteer species on the approved planting list must be established for at least 2 years to count towards
success and will be subject to the average height standard.
*Growing season for this site is to start no earlier than February 1 and range through November 30 as verified
by soil temperature and above ground growth and development of vascular plants. Measured success criteria
utilized May 5 through November 30 due to the construction timeline. Photo documentation of >50% leaf fall
of dominant tree species will be recorded in combination with soil temperature probe data to document end
of growing season. YR02+ growing seasons will be measured from February 1 – November 30th of each year
and will be supported by recorded soil temperature probe data and supplemented with photographic evidence
of above ground growth and development of vascular plants (i.e. emergence of herbaceous plants from the
ground; appearance of new growth from vegetative crowns; coleoptile/cotyledon emergence from seed; bud
burst on woody plants (2 or more species); emergence or elongation of leaves of woody plants; or emergence
or opening of flowers). The growing season has begun and is on-going if either of these conditions is met. The
beginning of the growing season will be indicated by whichever condition occurs earlier, and the end of the
growing season will be indicated by whichever condition persists later.
2.0 AS-BUILT CONDITION (BASELINE)
Construction started in December 2022 and ended with a final walkthrough on April 19, 2023.
The Site was planted on April 6, 2023. As-built and MY0 data collection occurred between April
and May 2023.
MY1 Monitoring Report (Project No. 100142) 6
Cool Run Mitigation Site Clearwater Mitigation Solutions
Brunswick County, North Carolina February 2024
In general, no significant issues arose during the construction of the Site. Upon completion of the
as-built it was noted that a cross-vane was installed in a slightly different location than proposed
in the construction plans. However, in consultation with the project engineer, it is unlikely that
the installed location will affect the stability and success of the project. The proposed location of
the structure and as-built location are currently stable. This location will continue to be
monitored and will be addressed in subsequent monitoring reports.
3.0 PROJECT MONITORING - METHODS
Monitoring will be conducted in accordance with 2016 NCIRT Guidelines. Monitoring will be
conducted by Davey Resource Group, Inc. based on the schedule below. Annual monitoring
reports will be submitted to the NCDMS by Clearwater Mitigation Solutions no later than
December 31 of each monitoring year data is collected. Monitoring parameters are summarized
in Table 4.

4.0 MONITORING YEAR 1 – DATA ASSESSMENT
Site visits were conducted through October 11-13 to collect annual monitoring data for the
project. Stream, wetland, and vegetation monitoring for the Site follow the approved success
criteria presented in the Mitigation Plan and summarized in Section 1.3; monitoring methods are
detailed in Table 4.
4.1 Stream Assessment
Geomorphology surveys for MY1 were conducted on October 13, 2023. It is important to note
that deviations in cross sectional areas over the course of the monitoring year are expected due
to normal scour and deposition of low gradient sand and bed systems. Refer to Appendix A for
the Visual Stream Morphology Stability Assessment Table. Refer to Appendix C for Stream
Geomorphology Data.
While stream banks remain stable, cross-sectional data indicates both Cool Run stream and UT1
have experienced aggradation over the past monitoring year. This can be attributed to the 5-7
inches of rain the site received within 24 hours from Hurricane Idalia in August 2023. It is likely
that sediment deposited during the heavy rain events will move through the system during the
following monitoring period as the stream system reaches equilibrium.

4.2 Hydrology Assessment
4.2.1 Groundwater Gauges
Seventeen groundwater monitoring gauges were installed throughout the site’s wetlands. Wells
that exceeded or met the defined 12% wetland success criteria included wells 3, 4, 5, 7, 14, and
15. These wells consecutively met success criteria for periods ranging from 26 to 63 days. A
remaining portion of the wells met 5% wetland hydrology (minimum criteria for a jurisdictional
wetland) throughout the growing season and narrowly missed the 12% success criteria. Wells 1,
8, 12, 13, and 16 were short of 12% by 1.5, 0.1, 0.6, 0.1, and 0.1 percent respectively. Eleven wells
throughout the site demonstrated at least 5% of wetland hydrology throughout the growing
season. The reference gauge located offsite in a stream valley was impacted by beaver behavior
throughout the monitoring period. Some data was retrieved but may be deemed inadequate for
the purpose of reference wetland conditions. The gauge will be relocated for the following
monitoring period to Ev Henwood Nature Park in a reference undisturbed stream valley. The
remaining wells, 2, 6, 9, 10, 11, and 17 fell short of meeting the defined 12% success criteria and
the 5% minimum wetland criteria. Their performance could be attributed to the inability to
capture the entire growing season. In total, due to a delayed gauge deployment, 83 days were
un-monitored from February 1 through April 25. This critical early growing season is typically the
wettest portion of the growing season. The Antecedent Precipitation Tool characterized this time
as mostly normal or dry conditions. In contrast, 21% of the data captured was described as
“wetter than normal conditions”. Therefore, only 79% of the captured data could be used to
determine success criteria. The additional precipitation and data captured during this period
could contribute to future success. Future monitoring of the complete growing season will
determine whether elevation and soil type may have contributed to the inability of some gauges
to meet success criteria. Please refer to Table 5 for summary of hydrologic monitoring and
Appendix D for the respective hydrographs, gauge locations, elevations, and soil profiles.

4.2.2 Bankfull Events
Bankfull events were monitored throughout 2023. Cool Run (S1) experienced three separate
bankfull events throughout the year: one event in April, one in August, and one in September.
The longest event occurred from August 30 to September 3 for a total of 5 consecutive days. UT1
(S2) experienced the most bankfull events throughout 2023 accumulating a total of 7 events.
Bankfull events were more frequent and prolonged in September compared to other months.
UT1 (S2) longest event occurred from August 30 to September 2. The bankfull events during
August 30 to September 3 were a result of Hurricane Idalia. The UT1 (S2) maintained flow for the
entire monitoring period, April 25 through November 30. Cool Run (S1) maintained flow for 190
consecutive days, April 25 to November 1. A brief dry period occurred between November 2 to
November 11, 9 days. Flow resumed after November 11. Please refer to Table 6 for a summary
of bankfull monitoring.

4.3 Vegetative Assessment
The MY1 vegetative survey was completed on October 11 and 13, 2023. Vegetation monitoring
resulted in a sitewide stem density average of 540 planted stems per acre, above the interim
requirement of 320 stems per acre required at MY3. An average of 4 species was documented
throughout the site. All 14 fixed vegetation plots and 3 random plots met the interim success
criteria. Plot 11 averaged 324 stems per acre. Although they currently meet the designated
success criteria, future supplemental planting may be required in this area. Sweet gum thinning
occurred throughout MY1. Herbicide was applied throughout the site on October 13. Additional
hack and squirt efforts were conducted throughout the year on larger Sweet Gum trees from the
drop structure to UT1. Species count ranged from three to seven species per plot. Plots 1, 7, 9,
and 13 possessed the lowest species count with three documented species while Plot 6 possessed
the most with seven documented species. Overall, planting zone 1 and planting zone 2 had an
average species count of four species. Please refer to Appendix A for Vegetation Plot
Photographs and the Vegetation Condition Assessment Table, and Appendix B for Vegetation Plot
Data.
4.4 Growing Season Determination
The growing season for MY01 is established as February 1 through November 30. Measured
success criteria utilized May 5 through November 30 due to the construction timeline.
Photographic documentation of incomplete abscission and suitable soil temperatures were
documented to support this claim. Soil temperatures distinguishing the growing season are
temperatures at 12 inches in depth and equal to 41° Fahrenheit as defined by the Regional
Supplement provided by the Corps of Engineers. Soil temperatures documented throughout the
year never fell below 55.9° Fahrenheit. The lowest temperature occurred on November 30th.
Growing season will continue to be monitored in Year 2. Collected data will capture soil
temperature and bud burst to support claims distinguishing the beginning of the growing season.
Dates agreed upon for the MY02 growing season will be the definitive growing season
parameters for the remainder of monitoring. Please refer to Appendix A for photo
documentation of deciduous tree leaf retention and Appendix D for soil temperature.
4.5 Monitoring Year 1 Summary
In summary, the site stream banks have remained stable and are performing as intended.
However, the stream channels have experienced aggradation over the monitoring period,
attributed to a hurricane event that moved through the area in August 2023. Most wells
throughout the site documented successful wetland hydrology or narrowly missed the success
criteria. By capturing the entire growing season in future monitoring years, successful wetland
hydrology for all gauges may be met. Stream flow was present in Cool Run for 190 days and UT1
for 219 days. In addition, multiple bankfull events were captured in both reaches. The site
averaged 519 stems per acre, on track for the defined 320 stems per acre necessary for success
in Year 3. All plots maintained an average greater than 320 stems per acre. However, Plots 3 and
MY1 Monitoring Report (Project No. 100142) 13

11 may need future supplementation to ensure their current average, 324 stems per acre,
continues to meet success criteria.

Note: The smaller the channel the closer the survey measurements are to their limit of reliable detection, therefore inter‐annual variation in morphological measurement (as a percentage) is by default magnified as channel size decereases. Some of the variability above is the result of this factor and some is due to the large amount of depositional sediments observed.

The above morphology parameters reflect the 2018 guidance that arose from the mitigation technical workgroup consisting of DMS, the IRT and industry mitigation providers/practitioners. The outcome resulted in
the focus on three primary morphological parameters of interest for the purposes of tracking channel change moving forward. They are the bank height ratio using a constant As‐built bankfull area and the cross
sectional area and max depth based on each years low top of bank. These are calculated as follows:
1 ‐Bank Height Ratio (BHR) takes the As‐built bankful area as the basis for adjusting each subsequent years bankfull elevation. For example if the As‐built bankfull area was 10 ft2, then the MY1 bankfull elevation
would be adjusted until the calculated bankfull area within the MY1 cross section survey = 10 ft2. The BHR would then be calculated with the difference between the low top of bank (LTOB) elevation for MY1 and the
thalweg elevation for MY1 in the numerator with the difference between the MY1 bankfull elevation and the MY1 thalweg elevation in the denominator. This same process is then carried out in each successive year.
2 ‐LTOB Area and Max depth ‐These are based on the LTOB elevation for each years survey (The same elevation used for the LTOB in the BHR calculation). Area below the LTOB elevation will be used and tracked
for each year as above. The difference between the LTOB elevation and the thalweg elevation (same as in the BHR calculation) will be recroded and tracked above as LTOB max depth.
