1.0 INTRODUCTION
1.1 Introduction
This monitoring report has been prepared by Soil & Environmental Consultants, PA (S &EC) to present
and evaluate site monitoring data for the period June 2012 through May 2013 for the North Carolina
State University (NCSU) Centennial Campus N -4 Cluster Stream Restoration project located in Raleigh,
Wake County, North Carolina.
The restored stream drains to an unnamed tributary of Lake Raleigh/Walnut Creek (B; NSW) in the
Neuse River Basin (030402, 27- 34- (3.5). A vicinity map is included as Figure 1. As a condition of
approval of the 401 Water Quality Certification (dated November 30, 2010), The North Carolina
Department of Natural Resources, Division of Water Quality (DWQ) requested that this project be
monitored for a period of five (5) consecutive years. This monitoring report provides data collected
during the second year of the five year monitoring period.
1.2 Project History
North Carolina State University restored a portion of stream at the NCSU Centennial Campus N -4
Cluster Site, consisting of approximately 142 linear feet (LF) of previously degraded channel, and the
construction of an additional 49 LF of stream following the removal of an existing pipe. Construction
drawings for the stream restoration were prepared by Little & Little Landscape Architects, PLLC of
Raleigh, NC. In March 2011, prior to construction, S &EC installed a reference hydrology monitoring
gauge upstream of the restoration reach, and rain gauge on -site.
Construction of the stream restoration was performed by Riverworks, Inc. of Cary, NC between July
2011 and August 2011. Construction oversight was provided by Little & Little Landscape Architects.
Following construction, an as -built survey of the restored stream was performed by Turner Land
Surveying, PLLC of Raleigh, NC in August, 2011. For reference, this survey is provided as Appendix F.
Subsequently, hydrology gauges were installed within the restoration reach, and monitoring of the
restored stream and buffers by S &EC began in August 2011. Planting of woody vegetation as per the
approved planting plan was performed by NCSU in November, 2011.
1.3 Project Components
As described on the approved Construction Drawings, restoration of the N -4 Cluster stream included
(but was not limited to) a restored dimension, pattern, and profile of the stream, the installation of rock
structures to provide for grade control and improve bed form, construction of a concrete sill at the
upstream end of the restoration and installation of an impervious geomembrane to reduce the potential
for the loss of channel hydrology of the restoration reach.
Prior to restoration of the stream, the stream buffer and surrounding area was covered with Kudzu
(Pueraria lobata). As part of the restoration, this invasive species was removed from the restored reach,
the upstream buffer, and the surrounding area to prevent future invasion. The 50 -foot stream buffer of
the restoration reach was then planted with woody tree and shrub species and seeded with herbaceous
ground cover.

2.0 MONITORING
The purpose of monitoring of the restored stream and buffer is to document the overall effectiveness of
the restoration, including stream stability, comparative hydrology of the upstream reference reach and
the restored reach, and the success of planted vegetation and absence of invasive species.
Site monitoring will be performed for a period of five years or until approval is given by DWQ to
discontinue monitoring.
This report serves as the Year Two Monitoring report. As per the agreed upon monitoring schedule,
hydrologic data collection during Year Two was performed quarterly, and stream stability monitoring
was performed (at least) annually. The monitoring frequency for Years Three through Five will also
consist of quarterly hydrology data collection and annual stream stability monitoring. Monitoring reports
will be submitted to DWQ by June 1"each year. For reference, the schedule of specific monitoring tasks
is provided as Appendix A.
Site monitoring dates and activities performed by S &EC during Year Two are described in the following

2.1 Methodology
This section includes information concerning; 1) hydrologic monitoring, 2) qualitative stream stability
monitoring, 3) qualitative vegetation monitoring, and 4) Qualitative Aquatic Organism Monitoring.
These data will be used for comparison with data from subsequent monitoring years.
2.1.1 Hydrologic Monitoring
A total of three (3) Infinities, U.S.A. hydrology monitoring gauges were installed on the site
along with a single Infinities, U.S.A. rain gauge. On March 18, 2011, prior to construction of the
stream restoration, one hydrology monitoring gauge was installed immediately upstream of the
restored stream reach to record hydrologic conditions adjacent to the reference reach. At this
time, the rain gauge was also installed to document site rainfall. On August 26, 2011,
immediately following construction of the stream restoration, two hydrology monitoring gauges
were placed adjacent to the restored stream channel; one adjacent to a riffle and one adjacent to a
pool. The locations of all hydrology monitoring gauges are shown in Appendix B on the
Monitoring Layout (Sheet 1). Download of hydrology data from on -site gauges was performed
quarterly during Year Two.
2.1.2 Stream Stability Monitoring
Sixteen (16) photographic monitoring points were established to qualitatively document stream
stability. The locations of these photo points are shown in Appendix B (Sheet 1). To assess
2

continued channel stability during Year One, photographs were taken at quarterly intervals for
comparison. DWQ requires stream stability documentation at photographic monitoring points to
be performed on an annual basis during Years Two through Five. During Year Two,
photographic monitoring at the established photo points was performed three times.
2.1.3 Qualitative Vegetation Monitoring
No specific vegetation monitoring or survival criteria were established by DWQ for this project;
however, qualitative evaluation and observations of planted specimens, herbaceous ground
cover, and invasive plant species were made during quarterly monitoring visits.
2.1.4 Qualitative Aquatic Organism Monitoring
No specific benthic macroinvertebrate or other aquatic organism monitoring was initially
required by DWQ for this project. Following Year One reporting, Mr. Eric Kulz requested
qualitative evaluation of aquatic organisms be included in subsequent monitoring reports. The
purpose of this is to provide an additional monitoring element by which the function of the
restored stream reach may be measured. Beginning with Year Two, visual observations of
aquatic organisms in and associated with the restored stream reach were made during quarterly
monitoring visits.
2.2 Results
This section includes a summary and discussion of site monitoring results for hydrology, stream
stability, vegetation, and aquatic organisms observed. For additional information, the interested reader is
referred to the appendices.
2.2.1 Hydrologic Monitoring Results
Data collected by the upstream reference gauge and the two restoration reach gauges was
compared to observe the effectiveness of the impervious geomembrane in reducing hydrologic
loss from the restoration reach. Unless otherwise noted, the results shown below reflect data
compiled for the period January 1, 2012 through May 20, 2013.
During Year 2 monitoring, water level at the upstream reference gauge has fluctuated between
approximately 2 inches above and 3.5 inches below the ground surface in response to recorded
rain events. The average water level at the reference gauge was 0.96 inch below the ground
surface.
Water level at restoration reach Gauge 1, adjacent to a riffle, showed distinct increases in
response to recorded rain events. Rainfall driven water level increases of over 5 inches were
common throughout Year Two monitoring. The maximum rainfall driven water level increase at
this gauge was approximately 10.5 inches. Water level at Gauge 1 fluctuated between 9.14 and
20.96 inches below the ground surface. The average water level at Gauge 1 was 18.39 inches
below the ground surface, a decrease of 0.01 inch in average water level from Year One
monitoring.
Restoration reach Gauge 2, adjacent to a pool, showed more uniform hydrology, with water
levels fluctuating less drastically in response to rainfall events. The maximum rainfall driven
water level increase at this gauge during Year Two was approximately 6 inches, an increase of 3
3

inches from Year One monitoring. Water level at Gauge 2 fluctuated between 13.61 and 21.13
inches below the ground surface. The average water level at Gauge 2 was 19.24 inches below the
ground surface, a decrease of 2.22 inches in average water level from Year One monitoring.
Rainfall recorded during 2012 by the on -site rain gauge (for the period January 1 through
December 31, 2012) totaled 32.22 inches.
The on -site rain gauge malfunctioned during 2013. As a result, no data was retrieved for the
period February 8, 2013 through May 20, 2013. Daily precipitation data for this period, collected
by the weather station at the nearby Lake Wheeler Road Field Laboratory (Station ID LAKE),
was downloaded from the State Climate Office of NC website. A comparison of recorded rainfall
data for the previous year (for the period February 2012 through May 2012) showed that the
LAKE station and the on -site rain gauge at the NCSU N4 stream restoration site recorded a
similar volume of rainfall, with a difference of only 0.61" over the four month period. Rainfall
recorded to date during 2013 by the on -site rain gauge (for the period January 1, 2013 through
February 7, 2013) and the LAKE weather station (For the period February 8, 2013 through May
20, 2013) totaled 12.91 inches.
Hydrologic and rainfall data are presented graphically in Appendix C. For reference, cross
sections (collected during Year One monitoring) at each hydrology gauge location are presented
in Appendix D.
2.2.2. Stream Stability Monitoring Results
Based on a comparison of photos taken during Years One and Two and general observation of
the condition of the restored stream during monitoring visits, the stream appears to have
maintained its constructed dimension, pattern, and profile with no indications of departure.
Natural sediment transport and sorting of stream bed material was observed, including the
formation and migration of bars and deposition of sediment. No excessive erosion around or
beneath any structures or down - cutting of riffles was observed. During the February and May
site visits, a few small areas on the stream banks were observed to be bare of vegetation. These
areas, which do not appear to have resulted in erosion to date, were brought to the attention of
NCSU Grounds Management and are planned to be selectively re- seeded. Any evidenced
erosion, bare banks, or failing structures observed in future monitoring years will be documented
and a plan implemented to repair problem areas.
Comparative site photographs are presented in Appendix E. The as-built survey of the restored
stream reach (by Turner Land Surveying, PLLC) is provided as Appendix F.
2.2.3 Qualitative Vegetation Monitoring Results
Although no specific vegetation monitoring or survival criteria were established by DWQ for
this project, observations of planted specimens made during quarterly monitoring visits suggest a
very high survival rate. The use of large, containerized trees and shrubs within the stream buffer
has led to the rapid beginning of a new canopy over the restored section of stream channel.
Mortality was noted only of a very few planted shrubs which were accidentally hit by a mower
during a one -time trimming of dense herbaceous temporary ground cover following the
restoration. Volunteer woody trees and shrubs were not observed within the restoration reach
buffers during Year Two monitoring.
4

Herbaceous permanent ground cover was observed to be generally vigorous and dense, and very
few areas were noted to be occasionally sparse in herbaceous cover during the course of
monitoring. As previously noted, a few areas lacking in ground cover on the stream banks will be
re- seeded in the coming weeks.
Control of invasive species, especially Kudzu (Pueraria lobata) has been ongoing since the
stream restoration. During Year Two monitoring, invasive species in and adjacent to the restored
stream buffer were closely monitored. A single Tree of Heaven (Ailanthus altissima) was the
only invasive plant noted to be within the restored stream buffer. Upstream of the restoration
reach, several invasive species are re- colonizing the stream buffer. These include Kudzu, Privet
(Ligustrum sinense), Multiflora Rose (Rosa multiflora), and Chinaberry (Melia azedarach). A
native, but undesirable species, Cattails (Typha latifolia) were observed within the stream
channel during Year Two.
During the May 2013 quarterly monitoring visit, S &EC personnel met on -site with NCSU
Grounds Maintenance staff to discuss the ongoing maintenance of undesirable vegetation in the
stream and buffers. Control of invasive species and selective herbicide wiping of cattails in the
restored stream is planned for the near future, and will continue as needed.
2.2.4 Qualitative Aquatic Organism Monitoring Results
At the request of DWQ, aquatic organisms associated with the restored stream reach were
observed during quarterly monitoring. A list of species observed is included below:
Species observed in the stream
Water Boatman
Physid Snails
Green Frog (Rana clamitans) tadpoles
Species observed adjacent to the stream
Green Frog adults
Squirrel Treefrog (Hyla squirrella) adults
Gray Treefrog (Hyla chrysoscelis) adults
Suspected crayfish burrows, possibly of White River Crayfish (Procambarus acutus)

2.3 Evaluation of Restoration Success — Year Two (2012 — 2013)
Based on our site observations (channel morphology, buffer vegetation, and aquatic organisms) and
recorded hydrology data, it is our opinion that the restored stream is functioning as intended.
The stream appears stable, planted trees and shrubs in the stream buffer are large and have shown
vigorous growth and very high survival, and herbaceous ground cover is dense. Although no definite
biological indicators of perennial flow were observed during aquatic organism observations, water in the
stream was observed to be flowing during all monitoring visits during Year Two.
Recorded gauge data during Year Two indicates a similar hydrologic regime as was observed in Year
One. This, combined with the consistent presence of flowing water during this year's site visits indicates
the stream will likely continue to function as intended. Based on collected data to date, the restoration
effort continues to show success during monitoring Year Two.
