Dear Mr. Thomas:
In accordance with Special Conditions "w" and "x" of the U.S. Army Corps of Engineers
( USACE) permit and "6" of the North Carolina Division of Water Quality (DWQ) permit, ECS
Carolinas, LLP (ECS) has prepared a report for the 2013 annual monitoring for stream
restoration and wetland creation and restoration of the Brush Creek Mitigation Areas. The
monitoring requirements for Horsepen Creek (HP -I, HP -II and HP -III) were completed in
2011. The monitoring requirements for Brush Creek (BC -I, BC -II and BC -III) were completed
in 2012. The enclosed report includes the third year of monitoring for Brush Creek Line -of-
Sight vegetative plantings. Based on the findings of the 2013 monitoring; ECS, on behalf of
the PTIA, requests that vegetation monitoring for the Brush Creek LOS sites be considered
complete. Our findings are detailed in the enclosed report.
If there are questions regarding this report, or a need for further information, please contact
us at (336) 856 -7150.
Respectfully submitted,
ECS CAROLINAS, LLP

BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT
MONITORING REPORT
ECS PROJECT No. 09- 12666H
1.0 INTRODUCTION
The Horsepen Creek and Brush Creek Mitigation Areas were identified as having potential to
satisfy 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 satisfied through the restoration of stream and wetland riparian habitats at
the above referenced sites as specified in US Army Corp of Engineers ( USACE) Permit
Number 200021655 and the NC Division of Water Resources (DWR) Permit Number 00 -0846.
This report includes the following mitigation monitoring efforts:
• Year 3 Line -of -Sight Vegetation Monitoring
1.1 Horsepen Creek
No monitoring was performed in 2013 at the Horsepen Creek mitigation site. The monitoring
requirements for Horsepen Creek were completed in 2011. Mr. John Thomas with the USACE
indicated in a letter dated June 19, 2012 that monitoring efforts at Horsepen Creek that are
required by the permit had been completed. A copy of the letter is attached.
1.2 Brush Creek
No monitoring was performed in 2013 at the Brush Creek mitigation sites (BC- I,BC -11 and BC-
III). The monitoring requirements for BC -I, BC -11 and BC -III were completed in 2012. Mr. John
Thomas with the USACE indicated in a letter dated June 24, 2013 that monitoring efforts at
Brush Creek mitigation sites have been completed as required by the permit. Please note that
cattail treatment at BC -1 wetland cell 2 was completed in July 2013. A copy of the 2013
USACE and NCDENR correspondence is attached.
1.3 Brush Creek Line -of -Sight
In November 2009, the PTAA received authorization to cut/clear trees located in certain
preservation tracts that were set aside by PTAA in accordance with the above referenced
permit. The purpose of the project was to clear the line -of -sight (LOS) between the air traffic
control tower and the new Runway 5L/23R and its associated taxiways as required by the
Federal Aviation Administration. As required by the permit modification, the PTAA replanted
the cleared preservation tracts in February /March 2010. The revegetated areas are monitored
in accordance with the Horsepen Creek and Brush Creek mitigation monitoring requirements.
This report includes the third year of monitoring for the Brush Creek LOS plantings.

ECS PROJECT No. 09- 12666H
2.0 PROJECT DESCRIPTION
The Horsepen Creek and Brush Creek Stream and Wetland Mitigation Project is located on
parcels southeast and northwest of the Piedmont Triad International Airport (PTIA) in
Greensboro, North Carolina. The Horsepen Creek and Brush Creek restoration areas, and
Brush Creek LOS areas are identified on Figure 1.

BRUSH CREEK STREAM AND WETLAND MITIGATION PROJECT
MONITORING REPORT
ECS PROJECT No. 09- 12666H
The Brush Creek mitigation site includes BC -1, BC -11 and BC -III located to the northwest of the
airport. BC -1 is a restored wetland that includes two cells that contain approximately 4.54
acres. BC -11 is a created wetland that is 9.5 acres in area. BC -111 is situated in the former
roadway of Old Oak Ridge Road and consists of approximately 2.06 acres of restored wetland
and approximately 450 linear feet of restored stream channel.
The Brush Creek line -of -sight revegetation areas include LOS -1, LOS -11 and LOS -III located
northwest of the airport along Brush Creek.
Figure 2 is a site location map (USGS Topographic Map, Guilford, North Carolina Quadrangle)
that identifies the project areas. The site plans are included in Appendix A.

3.0 MONITORING ACTIVITIES
3.1 Brush Creek Line -of -Sight
Year three monitoring was completed for the
(LOS I, LOS -II and LOS -III). The monitoring
counts (Appendix C) in pre - established plots.

revegetated wetlands cleared for line -of -sight
included visual observations and vegetation
4.2 Brush Creek Line -of -Sight Vegetative Monitoring
Based on vegetative sampling, LOS -I, LOS -II and LOS -III are each within the success range
for vegetative criteria. Additional planting in 2014 is not recommended. Wetland vegetation
data is included in Appendix C.
5.0 RESTORATION SUCCESS CRITERIA
5.1 Vegetative Sampling
Vegetation sampling plots were established to monitor the survival success of wetland
vegetation. The locations of these plots are distributed across the planted portions of the site
(see photos in Appendix B). The data resulting from the sampling of the vegetative plots can
be found in Appendix C.
Based on the sampling, LOS -I, LOS -II and LOS -III are within the success range for vegetative
criteria. Table 1 shows the current wetland stocking levels.

6.0 MAINTENANCE AND CONTINGENCY PLANS
6.1 New Development
Horsepen Creek
Monitoring at Horsepen Creek has been completed. See attached letter from Mr. John
Thomas with the USACE dated June 19, 2012.
Brush Creek
Monitoring at Brush Creek has been completed. See attached letter from Mr. John Thomas
with the USACE dated June 24, 2012.
Brush Creek Line -of -Sight
At the end of the third year of monitoring, herbaceous wetland vegetation is prevalent
throughout the wetlands in LOS -I, LOS -II and LOS -III. The woody vegetation requirements
have been met for each of the first three years of monitoring. In addition to the planted
vegetation, naturally regenerated vegetation was observed but was not included in the overall
tally. No additional planting is recommended.
6.2 Stream and Wetland Maintenance and Recommendations
No repairs /maintenance is recommended at this time.
7.0 COMMENTS AND OBSERVATIONS
Brush Creek Line -of -Sight
Wetland vegetation success (both survival rate and physical condition) is evident during the
first three years of monitoring. Based on the success after three years, it is apparent that the
success requirements at five years will also be fulfilled. Therefore, it does not appear that
additional vegetation monitoring is warranted. ECS, on behalf of the PTIA, requests that
vegetation monitoring for the Brush Creek LOS sites be considered complete.
