INTRODUCTION
HORSEPEN CREEK STREAM AND WETLAND MITIGATION PROJECT
MONITORING REPORT
ECS PROJECT No. 09-12663C
Horsepen Creek Mitigation Areas I, 11, and III (HP-1, HP-11 and HP-III, respectively) were
identified as having potential to help meet the compensatory mitigation requirements of the
Piedmont Triad Airport Authority (PTAA) for impacts resulting from the expansion of their
existing facilities. The objective of this project is to provide stream mitigation units (SMU) and
wetland mitigation units (WMU) to the PTAA to offset impacts in the Cape Fear 03030002
hydrologic unit. The mitigation units required are being accomplished through the restoration
of stream and wetland riparian habitats at the above referenced sites as specified in USACE
Permit Number 200021655 and DWQ Permit Number 00-0846.
The construction of HP-1 was completed in 2004/2005. The construction of HP-11 and HP-III
were completed in 2005/2006. The stream and wetland mitigation project was designed by
MacTec Engineering and constructed by Shamrock Environmental. Monitoring for HP-1 year
one was completed by Mactec (2005). ECS completed monitoring of HP-1 years two, three
and four (2006, 2007 and 2008) and HP-11 and HP-III years one, two and three (2006, 2007
and 2008). ECS performed the monitoring requirements for the project during 2009, which
includes the fifth year of monitoring on area HP-1 and the fourth year of monitoring on areas
HP-II and HP-III. This report details our findings.

MONITORING REPORT
ECS PROJECT No. 09-12663C
PROJECT DESCRIPTION
The Horsepen Creek Stream and Wetland Mitigation Project is located on parcels near the
Piedmont Triad International Airport (PTIA) in Greensboro, North Carolina. Restoration work
was completed in three reaches. These reaches are identified on Figure 1 below (Google
2007). Reach 1 (HP-1) was constructed a year prior to reaches 2 and 3 (HP-II and HP-III) and
is one year ahead in the monitoring schedule. Construction was completed in February 2005
by Shamrock Environmental Corporation. HP-II and HP-111 were completed in 2006. In order
to facilitate reporting of the whole site, these monitoring documents have been consolidated
into one report.

HP-1 includes a section of Horsepen Creek and a reach of stream that is an unnamed tributary
to Horsepen Creek (HP-I UT1) located to the west of Painter Boulevard. From the confluence
of Horsepen Creek, HP-1 UT1 proceeds upstream to a point where the stream runs through a
culvert under Ballinger Road.
HP-II is located to the east of Painter Boulevard and HP-1. HP-II includes a reach of Horsepen
Creek that begins on the east side of the culvert under Painter Boulevard. This second reach
of Horsepen Creek continues to the bridge at Ballinger Road. This is the end of the project for
HP-II.
HP-III is located to the east of HP-11. HP-III is a section of King George Branch that comprises
all of Reach 3. It extends north from a wood line to the point where HP-III runs under Ballinger
Road.

MONITORING ACTIVITIES
HORSEPEN CREEK STREAM AND WETLAND MITIGATION PROJECT
MONITORING REPORT
ECS PROJECT No. 09-12663C
Year five monitoring was completed for HP-I and year four monitoring was completed for HP-II
and HP-III. The monitoring was completed in November and December 2009. The data
analyzed includes stream channel cross sections (Appendix B) and stream channel profiles
(Appendix C) with a virtual reference station (VRS), pebble counts (Appendix D) with a
gravelometer, photographs (Appendix E) taken with a digital camera, monitoring well data
(Appendix F) collected from pre-established wells, and vegetation counts (Appendix G) in pre-
established plots and transects. Observations of structures, vegetation and problem areas
were made throughout the data collection process and are documented in this report.
MONITORING RESULTS
' Results of surveying do not reveal severe fluctuations in stream geometry including the overall
streambed elevation and sinuosity. Graphs depicting the survey results of stream channel
cross sections are included in Appendix B and stream channel profiles are included in
' Appendix C. The survey data indicates stable cross sections with no significant widening or
increases in depth in HP-I, HP-I UT1, HP-II or HP-III. Corrective actions are not
recommended.

In 2008 and 2009, scouring was observed along the tops of banks in each area. The scour
was minor and corrective actions were not recommended. During the 2009 monitoring period,
scouring on the tops of banks appeared to be improving. The previously scoured areas were
mostly vegetated and appeared more stable.
Over the course of the four and five year monitoring periods, the streambed material has
become coarser in both the riffle and pool sequences of the stream. The stream throughout all
reaches appears to be maturing with larger and coarser materials settling in the riffle
sequences and finer materials settling in the pool sequences. Graphs of pebble counts at
each of the cross sections are included in Appendix D.
Well data indicates that hydrology is present at levels above the monitoring success
requirements with the exception of one wetland cell (HP II - wetland cell 2) which was slightly
below monitoring success requirements. Graphs showing water levels in each of the wetland
cells are included in Appendix F.
Based on vegetative sampling, HP-I, HP-II and HP-III are each within the success range for
vegetative criteria. Significant increases in streamside vegetation and growth of woody
vegetation was observed throughout each of the reaches. Additional planting in 2010 is not
recommended. Stem count data is included in Appendix G.

RESTORATION SUCCESS CRITERIA
1 STREAM DIMENSION
2009 cross section data was collected at established monitoring locations using a geophysical
virtual reference system (VRS). A total of 18 cross sections were analyzed using Microsoft
' Excel software. Graphs of the resulting data are included in Appendix B. HP-I and HP-I UT1
were compared to Year Two, Year Three and Year Four monitoring and HP-II and HP-III were
compared to Year One, Year Two and Year Three monitoring. The cross sectional
' dimensions of the streams are stable compared to the previous year monitoring data. The
data does not reveal significant widening or increases in depth in HP-I, HP-I UT1, HP-II or HP-
III. The following visual observations were noted during recent site visits.
' Some erosion is present in the vicinity of Rootwad 3 (HP-I, Meander 1) and Rootwad 4 (HP-I,
Meander 2). The rootwads function properly during periods of normal flow. Therefore,
replacement/repair of the rootwads is not recommended. Woody vegetation is present in both
of these areas and appears to have minimized further bank erosion behind the root wads. In
addition it appears that any repairs would jeopardize existing well established vegetation. It is
recommended that periodic visual inspections of these areas be performed to determine if
conditions are worsening and to determine if repairs are needed.
The top of the right bank (when facing downstream) of HP-I between Meander 2 and Meander
3 was repaired in 2008 using reinforcement matting and clean fill material. Vegetative
plantings were added to this area in 2009. During recent bankful events, some erosion has
' occurred in this area of the stream. However, the vegetative plantings have minimized erosion
and helped to stabilize the bank. Therefore, repairs are not recommended at this time. It is
recommended that periodic visual inspections of this area be performed to determine if
' conditions are worsening and to determine if repairs or additional plantings may be warranted.
STREAM PATTERN AND PROFILE
' 2009 stream pattern and profile data was collected for the entire length of all reaches using a
geophysical VRS. Data collected includes thalweg, inverts of in-stream structures, water
surface, and low top of bank. This data was analyzed using Microsoft Excel software. For
HP-I and HP-I UT1, the 2009 data was compared to Year One, Year Two, Year Three and
' Year Four monitoring data, and for HP-II and HP-III the 2009 data was compared to Year One,
Year Two and Year Three monitoring data. This data is presented in graphs located in
Appendix C. There are no changes evident in stream meandering or in thalweg depth.
Elevation and slope of the riffle and pool sections are consistent with previous monitoring data.
The overall stream profiles appear to be stable with less than one-half foot of variation in
thalweg elevation compared to as-built and previous monitoring data. The only areas that
' contain a significant variation in thalweg are the areas in HP-I that previously contained beaver
dams. These areas are noted on the attached site plan. The local US Fish and Wildlife
Service officer has captured and relocated the beavers on multiple occasions. In 2009, beaver
' activity was observed but less prominant than in previous monitoring years.
STREAM BED MATERIAL ANALYSIS
' Stream bed material analysis was completed for all reaches at each permanent cross section.
A gravelometer was used to determine pebble size. These pebble counts were then analyzed
using Microsoft Excel software. The resulting data is included in Appendix D. Based on the
data, there does not appear to be a trend in material sorting from 2008 to 2009. In general, it
appears that the streambed material is coarser in the riffle and pool sequences of the streams
since construction. Compared to 2005, 2006, 2007 and 2008 data, there have been increases
in the mean diameter at each cross section. The stream throughout all reaches appears to be

maturing with larger and coarser materials settling in the riffle sequences and finer materials
settling in pool sequences.
PHOTOGRAPH REFERENCE SITES
Photographs were taken using a digital camera and these photographs are documented in the
Photo Log in Appendix E. Photographs of structures, bare vegetative areas, and areas of
instability are documented. The wetland photographs were collected in September and the
stream photographs were collected in November. Structures located in the field are identified
in the photo logs and the site plans located in Appendix A.
WETLAND HYDROLOGY
Wetland hydrology has been analyzed using monitoring wells with data loggers. Monitoring
wells were installed in each of the fourteen wetland cells. Data loggers gather water level
readings at 7:00 AM each day. These wells are downloaded monthly, and the resulting data
has been analyzed using Microsoft Excel software to determine the average depth to
groundwater. The graphs depicting this analysis are located in Appendix F.
Thirteen of the fourteen wetland cells met the wetland success criteria during 2009. Wetland
Cell 2 of HP-II did not meet the criteria. However, wetland Cell 2 of HP-II maintained
inundation and saturation within the upper 12 inches of the soil for 67 days out of the 226 days
of the growing season and for 37 days out of the last 51 days of the growing season. Based
on local weather data (NOAA.gov), this area of North Carolina was under "abnormally dry" to
,'moderate drought" conditions from July 2009 until November 2009. During a year with
normal precipitation, each of the cells has shown the potential to meet the wetland hydrology
success criteria.
BANKFULL EVENTS
Several bankfull events have occurred since construction as evidenced by flattened
vegetation, deposited sediments, and scour marks at all reaches. The vegetation was
flattened as a result of overland bankfull flow. Bankfull events have been observed in each of
the five years of monitoring for HP-1 and in each of the four years of monitoring for HP-II and
HP-III. Photographs documenting bankfull events that occurred in 2009 are included in
Appendix E.

VEGETATIVE PLANTING
Vegetation sampling plots were established at the restoration site to monitor the success of
wetland and riparian buffer vegetation. The locations of these plots were random but
distributed across the planted portions of the site (see photos in Appendix E). Combined, the
sampling plots in each mitigation area represent one-tenth of an acre. Each planted woody
stem was located and tagged for future identification. In addition to plots, multiple Riparian
Buffer Transects were sampled to identify vegetative success in the streamside vegetation
zones. The data resulting from the sampling of both the vegetative plots and buffer transects
can be found in Appendix G.
Mitigation areas HP-I, HP-II and HP-III are within the success range for vegetative criteria.
' Areas of HP-I and HP-II were replanted in Spring 2008. Tables 1, 2 and 3 show the current
wetland stocking levels of HP-I, HP-II and HP-III.

MORSEPEN CREEK STREAM AND WETLAND MITIGATION PROJECT
MONITORING REPORT
ECS PROJECT No. 09-12663C
At the end of the fifth year of monitoring, HP-1 appears to have met the requirements of a
successful stream and wetland mitigation project. Extensive monitoring over the past five
years has not identified severe changes or unstable conditions to the restored areas. There
has been at least one bankful event during each of the five monitoring years. Maturing
streamside vegetation has limited the erosive impacts of bankful events particularly in the
fourth and fifth years following construction. As a result, further monitoring of HP-1 does not
appear warranted. However, since there are minor areas with erosion at HP-1, it is
recommended that periodic inspections be performed to ensure that these areas fully stabilize
and to ensure that there are no new developments involving degradation of HP-I.
HP-11 and HP-111 appear to have met the fourth year of monitoring requirements. No repairs or
corrective actions are recommended for HP-II or HP-III.
Significant growth of woody and herbaceous streamside vegetation has improved from year to
year at each of the sites. As a result, areas of significant erosion following bankful events and
periods of heavy flow has been limited and the need for corrective actions has improved.
' Areas of HP-1 and HP-II that were repaired following the 2007 and 2008 monitoring periods are
stable. In 2008, the bank on the right side (when facing downstream) of the first meander
(Meander A) in HP-1 was repaired using a geo-lift. The top of the bank was reseeded and
restaked. The geo-lift appears to have stabilized the bank and further erosion has not
occurred.
C

The top of the right bank (when facing downstream) of HP-1 between Meander 2 and Meander
3 was repaired in 2007 and 2008. Vegetative plantings were added to this area in 2009. The
vegetative plantings have reduced the erosive effects of bankful events to this area. Periodic
visual inspections should be performed to determine if further corrective actions are
necessary. At this time, further corrective actions are not recommended.
Root Wad 2 in Meander 8 was repaired following the 2007 monitoring year. This area was
regraded, reseeded and live staked with black willows and silky dogwoods. Further erosion
has not been observed since the repairs were made.
Several areas of HP-II were reseeded following the 2007 monitoring period. Vegetation in
these areas is established and there has been no further erosion. No additional actions are
recommended in these areas.
Additional planting of HP-1 Wetland 3 and Wetland 5 and HP-II was completed following the
2007 monitoring period. Vegetative success was achieved in each of the wetland cells during
the 2008 and 2009 monitoring periods.
Following the 2008 monitoring period, erosion behind Rootwad 3 of Meander 6 (HP-1) was
corrected by regrading the slope, reseeding and matting the bank. Further erosion was not
observed during visual observations during recent site visits.
Thirteen of the fourteen wetland cells met the wetland hydrology success criteria during 2009.
Wetland Cell 2 of HP-II did not meet the criteria. However, Wetland Cell 2 of HP-11 maintained
inundation and saturation within the upper 12 inches of the soil for 67 days out of the 226 days
of the growing season and for 37 days out of the last 51 days of the growing season. Based
on local weather data (NOAA.gov), this area of North Carolina was under "abnormally dry" to
"moderate drought' conditions from July 2009 until November 2009. During a year with
normal precipitation, each of the cells has shown the potential to meet the wetland hydrology
success criteria.

STREAM MAINTENANCE AND RECOMMENDATIONS
' HP-1
The required five years of monitoring has been completed at HP-I. Monitoring over the past
five years has not identified severe changes or unstable conditions to the restored areas.
' Based on the monitoring efforts, further monitoring of HP-1 does not appear to be warranted.
However, since there are minor areas with erosion at HP-1, it is recommended that periodic
visual inspections be performed to ensure that these areas stabilize.
Periodic inspections are recommended in the following areas of HP-1:
• HP-1, Meander 1, Rootwad 3;
• HP-I, Meander 2, Rootwad 4; and,
• the top of bank (when facing downstream) of HP-1 between Meander 2 and Meander 3.
HP-11
' No maintenance or repairs are recommended at HP-II.
HP-III
No maintenance or repairs are recommended at HP-III.
General Recomendations
Minor scoured areas have been identified along each of the reaches. Corrective actions in
these areas are not recommended at this time as they are not a significant source of siltation
to the streams and repairs would remove established herbaceous and woody vegetation.
However, it is recommended that these areas be evaluated following bankful events to
determine if conditions are worsening.
WETLAND MAINTENANCE AND RECOMMENDATIONS
Vegetative success was achieved in each of the wetland cells during the 2009 monitoring
period. Additional maintenance in the wetlands is not recommended at this time.
Nuisance species such as cattail (Typha latifolia) were removed from HP-1 Wetland 5 during
' the 2006 monitoring period. No maintenance is recomended concerning cattail removal during
this period. However, cattails were observed in wetlands at HP-111 during 2009 and should be
monitored to ensure that a monoculture does not develop.

COMMENTS AND OBSERVATIONS
' At the end of the fifth annual monitoring period for HP-1 and the end for the fourth year
monitoring period for HP-II and HP-III, the streams and wetlands appear to be stable and
functioning. As with each of the previous monitoring periods, the source of concerns identified
' during this monitoring period include beavers and strong stormwater pulses.
No repairs are recommended at this time. As discussed, woody and herbaceous vegetation
has become denser and the severity of scouring over the project area has decreased from
' year to year. Bankfull events are common as observed and documented with photographs
and indicated by scouring and wracked debris along the tops of the banks of the streams.
Periodic inspections are recommended to ensure that minor areas of scouring do not become
a significant concern.
' In 2009, the impact of beavers was less compared to the previous years of monitoring.
However, signs of beavers remain at the site, particularly in HP-I. The beavers have been a
' source of detriment to stream structure and tree mortality in the wetlands and along the stream
banks. To date, the damage caused by beavers has been localized and reversible. Previous
years monitoring have shown that there is much less damage and long term negative impact
to the streams and vegetation the quicker the beavers are trapped and their dams removed.
' Once identified, it is crucial that the beavers are promptly trapped and relocated and that their
dams are removed.
