Subject: Response to DMS Comments for DRAFT Monitoring Year 4 Report
Thomas Creek Restoration Project, Wake County
DMS Project # 96074, DEQ Contract #5549, RFP# 16-005020
Mr. Dow:
Please find enclosed our responses to the NC Division of Mitigation Services (DMS) review comments dated
December 17, 2019 in reference to the Thomas Creek Restoration Project –DRAFT Monitoring Year 4
Report. We have revised the Draft document in response to the referenced review comments. Each comment
and its corresponding response is outlined below.
1.Digital files/drawings:
a. Please provide excel sheet including the raw streamflow gage and precipitation data. In this file, please
make note of the gauge type used. Please also label any probe or benchmark elevations, the raw and
corrected readings of the water elevations, and any offsets applied. DMS needs to be able to clearly
identify these key elevations before incorporating these into the DMS database for independent
calculation/verification.
Response: Baker will provide all of the raw data as described above (with additional labeling and
notations as requested) in the revised digital submission files.
2.Section 2.2 Vegetation Assessment:
a. The second paragraph states that “No Vegetation Problem Areas (VPAs) were identified in Year 4.”
Please restate this sentence to state that no additional VPAs were identified in Year 4.
Response: Baker has revised the report as requested.
3. Appendix B, Table 6:
a. Please update the table to reflect continuing low vigor areas identified in MY3.
Response: Baker has revised Table 6 as requested and added a notation explaining that by DMS
request this previously reported VPA is not shown on the CCPV as a VPA so as not to create
confusion between any potential new, current year VPAs for MY4 with those reported in
previous monitoring years. It is, however, shown on the CCPV as an area of maintenance having
received soil amendments.
4. Appendix E, Figure 8:
a.As discussed during the site visit, please update Figure 8 for Flow Gauge TMCK FL2 to call out the
point where flow potentially fell below the established surface water depth threshold.
Response: Baker revised the FL2 flow gauge graph. Upon closer review, the arrow drawn to show
when the start of the longest consecutive flow event began was drawn to the incorrect date.
Michael Baker Engineering, Inc.
8000 Regency Parkway, Ste. 600 | Cary, North Carolina 27518
Office: 919.463.5488 | Fax: [phone]

However, the consecutive flow length was calculated from the correct date and thus the 94-day
value shown in both the graph notation and in Table 13 are correct. We apologize for the
confusion.

5. As required by contract, specifically RFP#16-005020 Addendum No. 1, Baker must submit an updated
Monitoring Phase Performance Bond (MPPB) for Monitoring Year 5 (Task 11) to Jeff Jurek for his
approval before DMS approves this deliverable and the associated payment.
Response: Baker will have an approved monitoring bond in place before submitting an invoice for
payment for this monitoring year task.

As requested, Baker has provided one (1) hardcopy and one (1) pdf copy of the FINAL report, along with all
the updated digital files (to be sent by secure ftp link). Please do not hesitate to contact me should you have
any questions regarding our response submittal.

Sincerely,

Scott King, LSS, PWS

1.0 EXECUTIVE SUMMARY
Michael Baker Engineering, Inc. (Baker) restored 4,721 linear feet of perennial and intermittent stream and
enhanced 3,948 linear feet of intermittent stream as documented in the As-built Baseline Report. Baker also
planted approximately 14.4 acres of native riparian vegetation within the 22.7 acre recorded conservation
easement areas along all or portions of the restored and enhanced reaches (Reaches R1, R2, R3, R4, R5, R6,
R7, T1, and T2). The Thomas Creek Restoration Project (Site) is located in Wake County, North Carolina
(Figure 1), approximately 1.5 miles southwest of the Community of New Hill (Figure 1). The Site is located
within the NC Division of Mitigation Services’ (NCDMS) Targeted Local Watershed (TLW) 03030004-020010
(the Harris Lake Hydrologic Unit) of the Cape Fear River Basin and is located in what was formerly known as
the NC Division of Water Resources (NCDWR) subbasin 03-06-07. The project involved the restoration and
enhancement of a rural Piedmont stream system, which had been impaired due to past agricultural conversion
and cattle grazing.
Based on the NCDMS 2009 Cape Fear River Basin Restoration Priority (RBRP) Plan (DMS 2009), the Thomas
Creek Restoration Project area is located in an existing targeted local watershed within the Cape Fear River
Basin and is located within the Middle Cape Fear / Kenneth and Parker Creeks Local Watershed Planning
(LWP) area. The restoration strategy for the Cape Fear River Basin is to promote low impact development,
stormwater management, restoration and buffer protection in urbanizing areas, and buffer preservation
elsewhere.

The primary goal of the project was to improve ecologic functions through the restoration and enhancement of
streams and buffers in a degraded, urbanizing area as described in the NCDMS 2009 Cape Fear RBRP. Detailed
project goals are identified below:

• Create geomorphically stable conditions along the unnamed tributaries throughout the Site,
• Protect and improve water quality by reducing streambank erosion, and nutrient/sediment inputs,
• Restore stream and floodplain interaction by connecting historic flow paths and promoting natural
flood processes,
• Restore and protect riparian buffer functions and corridor habitat in perpetuity by establishing a
permanent conservation easement, and
• Improve aquatic and terrestrial habitat through improved substrate and in-stream cover, addition of
woody debris, and reduction of water temperature.

To accomplish these goals, the following objectives were identified:
• Restore existing incised, eroding, and channelized streams by providing them access to their relic
floodplains,
• Implement agricultural BMPs, including cattle watering stations, to reduce nonpoint source (NPS)
inputs to receiving waters,
• Prevent cattle from accessing the conservation easement by installing permanent fencing and thus
reduce excessive streambank erosion and undesired nutrient inputs,
• Enhance aquatic habitat value by providing more bedform diversity, creating natural scour pools and
reducing sediment from accelerated streambank erosion,

• Plant native species riparian buffer vegetation along streambank and floodplain areas, protected by a
permanent conservation easement, to increase stormwater runoff filtering capacity, improve
streambank stability and riparian habitat connectivity, and shade the stream to decrease water
temperature, and
• Control invasive species vegetation within much of the project area and, if necessary, continue
treatments during the monitoring period.

In accordance with the Mitigation Plan and the project-applicable DMS guidance document “Monitoring
Requirements and Performance Standards for Stream and/or Wetland Mitigation” dated 11/7/2011, no formal
vegetation plot monitoring was performed, nor were any stream cross-sectional surveys conducted as part of
this Year 4 monitoring effort. A visual assessment of the site is emphasized this year, with the full vegetation
and cross-section survey work to resume for the Year 5 monitoring in 2020.
From the Year 4 visual inspection monitoring, all stream reaches appear stable and functioning. All stream
riffle beds are vertically stable, the pools are maintaining depth, stream banks are stable and vegetating, and in-
stream structures are physically intact and performing as designed as reported in Table 5 (Appendix B). No
Stream Problem Areas (SPAs) were identified in Year 4.
As discussed in the Year 3 monitoring report, Baker had previously noted two short sections of minor bank
scour along Reach R2 resulting from Hurricane Florence. These areas were graded back by hand and were
seeded and replanted with additional livestakes in January 2019 (the exact repair locations are shown in the
CCPV). Subsequent inspection of these area revealed that they have remained stable and are vegetating well
as shown in the Maintenance and Repair Photographs, which can be found in Appendix B.
The Year 4 visual inspection monitoring also observed that the planted acreage performance categories were
functioning at 100 percent with no eroding or bare areas to report, nor any areas of poor growth as reported in
Table 6 (Appendix B). No Vegetation Problem Areas (VPAs) were identified in Year 4.
As discussed in the Year 3 monitoring report, Baker had previously noted one area of thin stem density roughly
0.20 acres in size along Reach T1. This area was supplementally planted with bareroot stems in January of
2019 with approximately 40 bareroot stems consisting of a mix of green ash (Fraxinus pennsylvanica), tulip
poplar (Liriodendron tulipifera), sycamore (Platanus occidentalis), river birch (Betula nigra), and white oak
(Quercus alba). Subsequent inspection of this planted area during monitoring activities in September and
October 2019 revealed they appeared to be alive and growing well, as numerous stems were quickly and easily
identified in the field and had leaves and/or bud scars to indicate seasonal growth and all-around vigor. Please
see the CCPV in Appendix B for the location of this supplementally planted area.
Also discussed in the Year 3 monitoring report was an area roughly 0.38 acres in size of low vigor/short stems
along the left floodplain of upper Reach R3. As noted in the report, soil tests had indicated that the area was in
need of soil amendments for improved growth. Accordingly, pelletized lime was applied in January of 2019
and fertilizer was applied in March and September of 2019. Additional soil testing will be conducted again in
2020 and the plants in this area will be inspected for anticipated improved growth and vigor. Please see the
CCPV in Appendix B for the location of this amended area.
Additionally, there were no areas of non-native invasive species vegetation observed during the Year 4
monitoring. However, several sections of stream along the upper and middle portions of Reach R2 and the
lower portion of Reach R4 were observed to have scattered pockets of native cattail (Typha latifolia) growing
in the channel. These sections were treated in March and April of 2019 to control their growth as shown in the
Maintenance and Repair Photographs in Appendix B. These areas will be monitored in the future and treated
again if necessary.
Year 4 flow monitoring demonstrated that both flow gauges (TMCK-FL1 and TMCK-FL2) met the stated
success criteria of 30 days or more of consecutive flow through Reaches 2 and 5 respectively. Flow gauge

TMCK-FL1 documented 179 days of consecutive flow in Reach 2, while flow gauge TMCK-FL2
documented 94 days of consecutive flow in Reach 5. The flow gauges demonstrated similar patterns
relative to rainfall events as shown in the flow gauge graphs in Appendix E.
During Year 4 monitoring, the Reach R2 crest gauge (crest gauge #1) documented one post-construction
bankfull event in April 2019. As bankfull events have now been documented in all four years of monitoring,
the project has more than met the bankfull standard required for credit release.
Summary information/data related to the Site and statistics related to performance of various project and
monitoring elements can be found in the tables and figures in the report Appendices. Narrative background and
supporting information formerly found in these reports can be found in the Baseline Monitoring Report and in
the Mitigation Plan available on the DMS website. Any raw data supporting the tables and figures in the
Appendices is available from DMS upon request.
This report documents the successful completion of the Year 4 monitoring activities for the post-construction
monitoring period.
2.0 METHODOLOGY
The seven-year monitoring plan for the Site includes criteria to evaluate the success of the stream and vegetation
components of the Site. The methodology and report template used to evaluate these components adheres to
the DMS guidance documents “Monitoring Requirements and Performance Standards for Stream and/or
Wetland Mitigation” (DMS 2011), and to the Monitoring Report Template, Version 1.5 (DMS 2012), which
will continue to serve as the template for subsequent monitoring years. In accordance with these documents
and the approved Mitigation Plan, no formal vegetation plot monitoring was performed, nor were any stream
cross-sectional surveys conducted as part of this Year 4 monitoring effort. A visual assessment of the site is
emphasized this year, with the full vegetation and cross-section survey work to resume for the Year 5
monitoring in 2020.
The specific locations of monitoring features, such as vegetation plots, permanent cross-sections, reference
photograph stations, crest gauges, and flow gauges, are shown on the Current Condition Plan View (CCPV)
map found in Appendix B.
All earthwork for project construction was completed in October of 2015, with subsequent as-built survey work
completed in November of 2015. All site planting (bareroot stems and live-stakes) was completed in January
of 2016. All the Year 4 visual site assessment data contained in Appendix B were obtained in September and
October of 2019.
2.1 Stream Assessment
The Project involved the restoration and enhancement of a rural Piedmont stream system that had been impaired
due to past agricultural conversion and cattle grazing. Restoration practices involved raising the existing
streambed and reconnecting the stream to the relic floodplain to restore natural flood regimes to the system.
The existing channels abandoned within the restoration areas were partially to completely filled to decrease
surface and subsurface drainage and to raise the local water table. Permanent cattle exclusion fencing was
provided around all proposed reaches and riparian buffers, except along reaches where no cattle are located or
cattle lack stream access.

2.1.1 Morphological Parameters and Channel Stability
A longitudinal profile was surveyed for the entire length of channel immediately after construction to
document as-built baseline conditions for the Monitoring Year 0 only. Annual longitudinal profiles
will not be conducted during subsequent monitoring years unless channel instability has been
documented or remedial actions/repairs are required by the U.S. Army Corps of Engineers (USACE)
or DMS.
As per the Mitigation Plan and DMS monitoring guidance for this project, no cross-section survey data
were collected for this Monitoring Year 4 assessment. Consequently, none of the cross-sectional survey
graphs (Figure 6) or morphology data (Tables 11a and 11b) are presented in Appendix D as in previous
monitoring reports.
2.1.2 Hydrology
To monitor on-site bankfull events, one crest gauge (crest gauge #1) was installed along the downstream
portion of Reach R2 at bankfull elevation along the left top of bank at approximately Station 38+90.
During Year 4 monitoring, one above-bankfull event was documented in April 2019. Further details
of the crest gauge readings are presented in Table 12 in Appendix E, and photographs can be found in
Appendix B.
To monitor flow on restored reaches, two flow gauges were installed on site; TMCK-FL1 on Reach 2
(Station 20+75), and TMCK-FL2 on Reach 5 (Station 33+90). The Year 4 flow monitoring data
demonstrated that both flow gauges met the stated success criteria of 30 days or more of consecutive
flow. The gauges also demonstrated similar patterns relative to rainfall events and can corroborate
reported overbank flow events from the crest gauge, as shown in the flow gauge graphs found in
Appendix E.
As the observed monthly rainfall data for the project presented in Figure 9 in Appendix E demonstrates,
the past 12 months have varied dramatically as compared to historic average precipitation. A total of
46.5 inches of rainfall was observed for the project (using the nearest NC-CRONOS station KTTA),
while Wake County averages 43.8 inches of annual rainfall, an excess of just 2.7 inches. However, the
winter of 2018-2019 saw much greater than average rainfall totals, while several months in the summer
and fall saw much less than average rainfall totals. In fact, the Site was under stage D1 – Moderate
Drought conditions as of 10/15/19 as per the NC Drought Management Advisory Council.
2.1.3 Photographic Documentation
Representative stream photographs for Monitoring Year 4 were taken along each Reach in September
2019 and are provided in Appendix B.
2.1.4 Visual Stream Morphological Stability Assessment
The visual stream morphological stability assessment involves the qualitative evaluation of lateral and
vertical channel stability, and the integrity and overall performance of in-stream structures throughout
the Project reaches as a whole. Habitat parameters and pool depth maintenance are also evaluated.
During Year 4 monitoring, Baker staff walked the entire length of each of the Project reaches several
times throughout the year, noting geomorphic conditions of the stream bed profile (riffle/pool facets),
both stream banks, and engineered in-stream structures. Representative photographs were taken per
the Site’s Mitigation Plan, and the locations of any SPAs were documented in the field for subsequent
mapping on the CCPV figures. There were no SPAs noted during Year 4 monitoring as described
above. A more detailed summary of the results for the visual stream stability assessment can be found
in Appendix B, which includes supporting data tables and figures, as well as the general stream photos.

2.2 Vegetation Assessment
In order to determine if the success criteria were achieved, vegetation-monitoring quadrants were installed and
are monitored across the site in accordance with the CVS-DMS Protocol for Recording Vegetation, Version 4.1
(Lee 2007) using the CVS-DMS Data Entry Tool v. 2.3.1 (CVS 2012). The vegetation monitoring plots cover
a minimum of 2 percent of the planted portion of the Site with sixteen plots established randomly within the
planted riparian buffer areas per Monitoring Levels 1 and 2. The sizes of individual quadrants are 100 square
meters for woody tree species.
As per the Mitigation Plan and DMS monitoring guidance for this project, there was no vegetation plot
monitoring conducted for the Year 4 monitoring effort, and thus no vegetation data summary tables are included
in Appendix C as in previous monitoring reports. However, as reported in Table 6 (Appendix B), the planted
acreage performance categories were functioning at 100 percent with no bare areas to report, no current low
stem density areas, and no new areas of poor growth rates. No additional Vegetation Problem Areas (VPAs)
were identified in Year 4.

Notes:
† Starting in MY2, Reach 2 was broken up into an upstream and downstream component based on restoration approach as per DMS request. None of the actual restored lengths have changed, although the credits for
R2 (downstream) were adjusted as explained below.
* Starting in MY2, the SMU credit numbers used for these reaches were taken directly from the mitigation plan credit table (Table 5.1) as per DMS/IRT instruction, and vary from those presented in the baseline and MY1
monitoring reports. This was done because credits were originally calculated along the as-built thalweg but have been updated to be calculated along stream centerlines for MY2 onward after discussions with the IRT
stemming from the April 3, 2017 Credit Release Meeting. Stationing and Restoration Footage numbers reported herein and on all subsequent monitoring reports will remain as reported from the as-built survey. As Reach R
was not originally subdivided, the credits were reduced from the downstream section where the bulk of differences are expected to have occurred, though the total combined credits equal the original value for R2 as found in
the approved mitigation plan.
** Starting in MY3, as per DMS/IRT instruction, this column was added to the table showing the design reach lengths taken from the mitigation plan (Table ES.1). Please note these numbers did not remove non-creditable
sections such as easement breaks for crossings from their calculations.
