Re: Cool Run— MYO As -Built Report— Response to Comments (DMS Project No. 100142)
USACE Action ID No. SAW-2020-01428 / DWR Project No. 20200712
Dear Mr. Dow,
Please find below the response to comments for the Cool Run MYO As -Built Report provided on
August 11, 2023:
Report Comments:
1. Table I — Stream mitigation credits were calculated from the as -built lengths. Please correct to
calculate credits from mitigation plan lengths.
Re: Corrected.
Table 2 — The success criteria column in the first row states that you will "Document four overbank
events in separate monitoring years for at least 30-consecutive days." Please separate different
success criteria and re -word. As discussed briefly at the site visit, since UT1 is classified in the mit
plan as intermittent, there will be a flow monitoring requirement to demonstrate a minimum of 30
days consecutive flow (see DWR comment 914 from the final mitigation plan).
Re: Success criteria above differentiated and corrected.
Section 1.1 states that planting was completed on April 20th , but Section 2.0 and Table 11 state
April 6. Please clarify.
Re: The Site planting was completed on April 6, 2023. Corrected.
4. Section 1.2 — Success Criteria table indicates that 12% of the growing season will be 36 days. Has
the final growing season been established? If so, please provide the dates and how it was
determined. Please note that any start date prior to 3/1 requires a discussion of bud burst of species
observed (must be more than one) and supporting photo documentation, and similar for senescence
to determine the end date.
Re: Planting for the Site was completed on April 6, 2023. Groundwater water gauges
and soil temperature probes for the Site started collecting monitoring data on April 27,
2023. Growing season for W1 is proposed to begin on April 27, 2023, the date
groundwater gauges and soil probes began collecting data. The end of the W1 growing
season will be determined by photo documentation of >50% leaf fall of dominant tree
species and recorded in combination with soil temperature probe data to document the
end of growing season, up until November 30'h with November 30'h being the latest
possible date for the end of the growing season. The documented ending date of the
W1 growing season will establish the end date of the growing season for the remainder
of the monitoring period MY2-MY7. The start of the growing season for the Site will be
established in 2024, utilizing recorded soil temperature, supplemental 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 above metrics used to identify the start of the growing season will be
collected starting February 1, 2024, with the start of the growing season to begin no
earlier than February 1st. Similar to the identified ending date in 2023, the identified
start date of the growing season established in 2024, will be utilized as the beginning
date of the growing season for the remainder of the monitoring period MY2-MY7.
CCPV (Figure 1)
a. Please color code all veg plots based on meeting (green) or not meeting (red) vegetative success
criteria. Please do the same with wetland monitoring wells in MY I.
b. Recommend differentiating stream gauges based on their intent, i.e., to monitor overbank
events, or flow, or both.
c. Recommend removing the old ditch labeling NS2, NS3, etc.
d. It may be helpful for reviewers to label UT1 and Cool Run's different reaches on the map.
Re: Corrected per recommendations.
6. Appendix C — As discussed at the site visit, please label XS1 as the riffle and XS2 as the pool.
Recommend removing BHR calculation from pool cross sections here and in Table 10.
Re: Corrected per recommendations.
Tables 9A, B, & C — The MYO BHR numbers appear to be incorrect. They are identical to the Max
Depth numbers.
Re: Corrected.
Record Drawings Comments:
8. In the future include all surveyed in -stream structures from the as -built survey on the record
drawing.
Re: Noted and will be included in the future.
9. Sheet AB-04D — recommend keeping the "Cross Vane Relocated" callout and in addition coloring
the relocated cross vane red, or adding an arrow to draw attention to indicate that it is the structure
that was moved.
Re: Corrected per recommendations.
10. To reduce confusion, our recommendation is to change the red text for "As -Built Centerline" in
the longitudinal profile black since it is not a construction deviation.
Re: Corrected per recommendations.
Boundary Inspection Comments:
11. Recommend that each corner is witnessed on the State held CE side.
Re: Noted and will be corrected in future.
12. Recommend checking the line marking in all forested areas to ensure the marking is aligned with
the surveyed CE line. In these areas, paint and signs posted on trees at intervals of 100 ft, less

than the required 200 ft, will be helpful in reducing encroachments and allowing for ease of
future boundary inspections.
Re: Our surveyor, K2 Design Group, will be further marking and correcting the CE
boundary in the winter of 2024 per the recommendations.
13. Where the hunting stand was identified, the CE line should be accurately located by a surveyor
and a determination regarding its proximity to the CE should be made. If it is located inside the
CE, as it appeared using the Trimble R2 unit, the stand should be moved to outside of the CE
area.
Re: Noted. this will be verified and corrected as needed. A CE witness post and sign will
be installed near this location.
14. Speak with the farmer to ensure that there will be no further damage to the CE related to the corn
planted inside the easement area. Monitor to ensure the expected density and species of trees
remain viable in this corn planted area. If not, these impacted areas should be replanted.
Re: We have spoken with the farmer and land owner. There is to be no further damage
associated with the planted corn and/or future agricultural activities adjacent to the CE.
15. Review included KML for reference and location details of action items.
Re: Thank you for the .KMZ file and documentation. This is very helpful in
communicating the additional boundary marking needs and scope to us and the
surveyor.

Cool Run Stream and Wetland Mitigation Site Clearwater Mitigation Solutions
Brunswick County, North Carolina August 2023

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 2,028 linear feet of Priority I stream restoration, 592 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 2,422.00 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 has been in use for
agriculture and silviculture since at least the 1950's. Based on historical aerial photography, Cool
Run appears to have been relocated and channelized in the late 1950's, and UT 1 appears to have
been channelized prior to 1956. The floodplain of Cool Run has been historically modified and
logged over the last several decades. The site was last logged between 2016 and 2018. Site
design was completed in June 2022. Construction started 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 Q.

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, 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.
*See Section 1.3, below, for proposed MY1 growing season dates and establishment of MY2-MY7 growing
season dates.
1.3 Growing Season
Planting for the Site was completed on April 6, 2023. Groundwater water gauges and soil
temperature probes for the Site started collecting monitoring data on April 27, 2023.
Growing season for MY1 is proposed to begin on April 27, 2023, the date groundwater
gauges and soil probes began collecting data. The end of the MY1 growing season will be
determined by photo documentation of >50% leaf fall of dominant tree species and
recorded in combination with soil temperature probe data to document the end of growing
season, up until November 30t" with November 30t" being the latest possible date for the
end of the growing season. The documented ending date of the MY1 growing season will
establish the end date of the growing season for the remainder of the monitoring period
MY2-MY7. The start of the growing season for the Site will be established in 2024, utilizing
recorded soil temperature, supplemental photographic evidence of above ground growth
and development of vascular plants (i.e. emergence of herbaceous plants from the ground;
MYO Monitoring Report (Project No. 100142) page S

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 above metrics used to identify the
start of the growing season will be collected starting February 1, 2024, with the start of the
growing season to begin no earlier than February 1st. Similar to the identified ending date
in 2023, the identified start date of the growing season established in 2024, will be utilized
as the beginning date of the growing season for the remainder of the monitoring period
MY2-MY7.
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 MYO data collection occurred between April
and May 2023.
In general, no significant issues arose during the construction of the Site. A sealed half-size set of
record drawings are provided in Appendix F, which includes the post -construction survey,
alignments, structures, and monitoring features. These include redlines for any significant field
adjustments made during construction that differ from the design plans. 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 be continued 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. A summary of monitoring
is outlined in Section 3.1. 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.

4.2 Hydrology Assessment
Seventeen groundwater monitoring gauges were installed throughout the Site's wetlands.
Hydrologic data will be collected and reported during MY1 (2023).
4.3 Vegetative Assessment
The MYO vegetative survey was completed on April 26, 2023. Vegetation monitoring resulted in
a sitewide stem density average of 712 planted stems per acre, above the interim requirement
of 320 stems per acre required at MY3. All 14 fixed vegetation plots and 3 random plots met the
interim success criteria. Please refer to Appendix A for Vegetation Plot Photographs and the
Vegetation Condition Assessment Table, and Appendix B for Vegetation Plot Data. No vegetation
areas of concern were identified during MYO.
4.4 Monitoring Year 0 Summary
In summary, the site streams are stable and performing as intended and vegetation
establishment across the site appears to be on target to meet success criteria for permanent and
random plots. Periodic monitoring will continue to be conducted to identify any areas of concern
in the future.
