Second Year Monitoring Report: Channel Stability
New Garden Road Widening Phase II Project No. P -3741
Introduction
The New Garden Road Widening Phase H 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 relocated stream reaches were assessed using Rosgen Level II Classification methods. The
following end of second year survey was conducted to evaluate and document the conditions of
the relocated stream channels following two years after the completion of construction. This data
will be compared to the as-built survey which provided a baseline for these future monitoring
events as well as the first year survey.

Second Year Monitoring Report: Channel Stability
New Garden Road Widening Phase II Project No. P -3741
Channel Stability
A geomorphic survey was performed by engineers from USI with the assistance of a scientist
from CWS on March 19, 2013 following two years after the construction of the new stream
channels. The survey included a longitudinal profile, a cross sectional survey, substrate sampling
(Wolman reach -wide pebble count), and photo documentation of each of the stream reaches.
This data was used to classify each reach using the Rosgen Level H system. Bank pins were also
checked on both reaches to monitor bank stability.
Surveying methods (using a rod, level, and tape) followed the guidelines given in Stream
Channel Reference Sites: An Illustrated Guide to Field Technique, General Technical Report
RM -245, United States Department of Agriculture, Forest Service. A relative benchmark for the
Second Year survey was established on the top of an existing sanitary sewer manhole
immediately adjacent to New Garden Road. The surveys of both streams were tied together to
the top of the sanitary sewer manhole with a given elevation of 100.00. The actual elevation of
the existing sanitary sewer manhole as a permanent benchmark is 775.70. This is shown in the
Raw Data portions of the Appendices. The Raw Data also shows the correction of the elevations
taken during the survey to actual elevations.

As part of the Second Year survey for the project, all areas of the project were photo

photographed facing upstream and downstream. Stream bed and banks were photographed for
visual comparison of stability. Representative photographs are included in Photopage 1
(Appendix A). The locations and directions of each of these photographs are shown in Figure 2
(Page 5). As an aside, the same locations and directions were used for these photographs as
those taken during the As -Built and First Year surveys.

Channel Stability
Main Tributary #2
Main Tributary #2 flows north through the project area and through the new culvert installed
beneath the widened New Garden Road. The Second Year survey of Main Tributary #2 was
conducted on March 19, 2013 by representatives from USI and CWS. The relocated stream
channel exhibited substrate consisting of fine gravel (D50 = 5.7 mm). The channel slope is 0.003
ft/ft with a sinuosity of 1.18. The average bankfull width and depth for this reach are 27 feet and
1.86 feet, respectively. The average bankfull cross sectional area for riffle portions of the stream
is 50.09 ft2. The average flood -prone area width for Main Tributary #2 is approximately 60 feet.
The new stream channel has a Rosgen Level H classification of C5.
Permanent cross sections were established during the As -Built survey and marked with rebar to
allow future monitoring of the same locations. Figure 2 on page 5 shows the locations of these
permanent cross sections. The As- Built, First Year, and Second Year conditions of Main
Tributary #2 (Cross Sections A and B) are summarized below in the following tables. Channel
cross sections, the longitudinal profile, and pebble count data for Main Tributary #2 are included
in Appendix B.

Tributary A
Tributary A is a minor tributary which flows west along the toe of the widened New Garden
Road embankment to its confluence with Main Tributary #2. The Second Year survey of

relocated stream channel exhibited substrate consisting of medium gravel (D50 = 8.0 mm). The
channel slope is 0.015 ft/ft with a sinuosity of 1.37. The average bankfull width and depth for
this reach are 17 feet and 1.58 feet, respectively. The average bankfull cross sectional area for
riffle portions of the stream is 26.85 ft2. The average flood -prone area width for Tributary A is
approximately 45 feet. The new stream channel has a Rosgen Level H classification of E4.

Comments
The channels (Main Tributary #2 and Tributary A) relocated as part of the New Garden Road
Widening Phase II Project appear to be geomorphically and hydraulically stable with regard to
pattern, profile, and dimension. Other than ongoing monitoring and observation there are no
recommendations to perform any remediation at this time.
