First Year Monitoring Report: Plant Survival
New Garden Road Widening Phase II Project No. P -3741
Introduction
The New Garden Road Widening Phase II Project is located in Greensboro, North Carolina as
shown on the Site Location Map (Figure 1) on the next page. Construction of this project
necessitated the relocation of portions of two tributaries to Horsepen Creek, Main Tributary #2
(South) and Tributary A (North). The relocation of these stream reaches was completed in
March 2011. The stream relocations were permitted through the U.S. Army Corps of Engineers
(Action I.D. SAW 2007 - 03980) and the North Carolina Department of Environment and Natural
Resources (DWQ Project #06 -0684) and required a Level 1 Stream Restoration Mitigation and
Monitoring Plan for this project. This level of monitoring includes the establishment of photo
reference sites, plant survival monitoring, and channel stability monitoring.
The following end of first year survey was conducted to evaluate and document the conditions of
the relocated stream channels and associated riparian plantings following one year after the
completion of construction. This data will be compared to the As -Built survey which provided a
baseline for these future monitoring events.
Methods
Photo Reference Sites
Photographs were taken during:
1) First Year Survey for Plant Survival on August 28, 2012
Stream banks and adjacent areas were photographed for visual comparison of plant survival and
groundcover.

Plant Survival
A vegetation survey was performed by engineers from U.S. Infrastructure of Carolina, Inc. (USI)
with the assistance of a scientist from Carolina Wetland Services, Inc. (CWS) on August 28,
2012 following one year after the installation of the new plantings. Vegetation monitoring plots
were established on both sides of each tributary during the As -Built Survey. The corners of each
monitoring plot were marked with PVC pipe during the As -Built Survey so that the same plots
can be used as the monitoring efforts continue for the next several years. Monitoring plots
extend from the stream edge to the furthest extent of planted area. A stem count of each species
occurring within each monitoring plot was conducted.
Results
Photo Reference Sites
As part of the First Year survey for the project, all areas of the project were photo documented.
Plantings were photographed for visual plant survival comparisons. Representative photographs
of the monitoring plots are included in Photopage 1 (Appendix A). The locations and directions
of each of these photographs are shown in Figure 3 (Page 4). As an aside, the same locations and
directions were used for these photographs as those taken during the As -Built survey.
Plant Survival
A total of eight vegetation monitoring plots were established during the As -Built survey. Four of
these plots (Plots IA, 2A, 3A and 4A) were established in areas that were planted with live
stakes. The remaining four plots (Plots 1B, 2B, 3B and 4B) were established in areas that had
been planted with containerized trees and shrubs. As part of the First Year survey, plant survival
within these monitoring plots was surveyed on August 28, 2012. Table 1 on page 5 summarizes
the overall data and information for the vegetation monitoring plots for both the As -Built and
First Year surveys.

When Plot 3B was established during the As -Built survey, it was located such that it would fall
outside of the existing sanitary sewer easement to the west. However, during the First Year
survey it was noted that approximately half of Plot 3B had been routinely mowed and maintained
as part of the existing sanitary sewer easement. Because of these maintenance activities, the
groundcover and stem counts in Plot 3B are much lower when compared to the other vegetation
monitoring plots.

Summary
Comments
As shown in the photographs in Appendix A, the groundcover has filled in well along and
adjacent to the channels (Main Tributary #2 and Tributary A) relocated as part of the New
Garden Road Widening Phase II Project. The data in Table I on page 5 indicates that the overall
coverage has gone from 76% during the As -Built survey to 91% during the First Year survey.
Additionally, plant survival of the live stakes as well as the trees and shrubs appears to be
variable but overall remains fairly good. Other than ongoing monitoring and observation there
are no recommendations to perform any remediation at this time.
