March2011
I. Executive Summary
The Mary's Creek (EEP #241) stream restoration project consists of 2,082 linear feet of
stream restoration with just over 7.3 acres of buffer restoration. The project is in
Alamance County north of Siler City, north of Greensboro Chapel Hill Road (SR 1005)
and east of Lindley Mill Road (SR 1003) (Figure 1). Site construction and plantings were
completed in March of 2006. The goals and objectives for Mary's Creek (EEP 4241)
stream restoration are:
• Improving water quality
• Providing wildlife habitat through the creation of a riparian zone
• Improving aquatic habitat with the use of natural material stabilization structures
and a riparian buffer
• Excluding cattle from the stream
• Reducing nutrient loads from entering the stream through a filtration buffer
• Increasing the streams access to its floodplain
• Reducing erosion and sedimentation
Level II of the CVS -EEP protocol was administered for Monitoring Year (MY) -04,
which includes planted woody stems and natural woody stems. Three vegetation
monitoring plots (1, 2, and 3) were added in MY -02 to the original two established during
baseline data collection. Planted stems could not be distinguished from natural stems
during the MY -02 vegetation data collection, therefore all stems were recorded as natural,
except for three black willow livestakes located within Plot 4. Including all five
monitoring plots, there are 2695stems /acre including natural and planted stems. The
success criterion for planted woody species is 320 stems /acre after MY -03. A mortality
rate of ten percent will be allowed after MY -04 (288 stems /acre), with another ten
percent allowed after MY -05 (260 stems /acre). An accurate number of planted stems
/acre could not be determined since the planted stems could not be distinguished from
natural stems.
Invasive exotics and areas of low stem densities are the only notable vegetation problems
areas for MY -04. Tree of heaven (Ailanthus altissima) and Chinese privet (Ligustrum
sinense) have reached levels of concern as well two areas of low stem densities and are
depicted in the Current Conditions Plan View (Appendix B). Other invasive exotics
observed within the conservation easement include tall fescue (Schedonurus
arundinaceus), Gill over the ground (Glechoma hederacea), Johnson grass (Sorghum
halapense), Japanese honeysuckle (Lonicera japonica), Japanese stiltgrass (Microstegium
vimineum), and multiflora rose (Rosa multiflora). According to the NC Native Plant
Society, all of these species, with the exception of tall fescue, Johnson grass, and gill over
the ground, are classified as "Rank 1 ", which is defined as exotic plant species that have
invasive characteristics and spread readily into native plant communities, displacing
native vegetation. Johnson grass and gill over the ground are classified as "Rank 2"
which is exotic plant species that display some invasive characteristics, but do not appear
to present as great a threat as Rank I species. Although these species have been given
these ranks, the functionality of the project is not expected to be impaired significantly by
these species. Tree of Heaven, Chinese privet, and multiflora rose are considered a
Mary's Creek Stream Restoration Year 4 Monitoring Report-FINAL
NCEEP Project number 241 Year 4 of 5
The Catena Group 1 March 2011
species of "High Concern" according to EEP's invasive plant ranking list. Tall fescue,
Johnson grass, and Japanese stiltgrass are species of "Low /Moderate Concern ". The
conservation easement contains tall fescue that resided within the seedbank pre -
construction and is still the dominant grass in the adjacent cattle fields. For additional
information relating to vegetation, see Appendix C.
Overall, the banks are stable and well vegetated along all project stream reaches. The
majority of the structures are also functioning properly with little evidence of needed
repairs with the exception of the two end structures on Mary's Creek that were noted as
degraded in MY -02. Previously reported problems with the structure at station 19 +75
continues to exhibit signs of piping, but has not degraded further as compared to MY -03.
The piping of the structure at 20 +95 reported in MY -03 has appeared to have stabilized
and is not exhibiting signs of degraded structural integrity. Rills were observed along the
fence line of the stream crossing of Mary's Creek which is outside of the EEP
conservation easement. However during a second site visit it was noted that the
landowner had filled in the rills. The steep roadway slope at the crossing makes the
crossing approach susceptible to erosion. Erosion has slowed on the upstream face of
the crossing from previous monitoring year; this area will continue to be observed due to
its lack of armoring.
Changes from MY -03 to MY -04 in the main channel are minimal. Riffle and pool
stability and performance are comparable to MY -03. The riffle substrate has fined
slightly placing the distribution closer to the MY -02 samples. The bedrock outcrop at
station 24 +50 is still causing minor backwater effects upstream more than 200 feet. The
bed of the main channel remains stable with no significant aggradation or degradation.
This is also reflected in a comparison of the cross sectional data between MY -03 and
MY -04. The structures at stations 25 +25 and 26 +00 that exhibited problems in MY -02
and MY -03 have failed and boulders have dislodged and moved slightly downstream.
These two structure failures are not causing stream integrity problems. The vane arms
are still intact, and are successfully providing bank protection. The bedrock directly
upstream is preventing any downcutting of the stream. The erosion at the upstream
culvert crossing face has slowed and some additional vegetation growth was observed.
The tributary also exhibited minor changes from MY -03 to MY -04. The reach is stable
and the banks and channel are heavily vegetated. Some of the structures are difficult to
locate due to the heavy vegetation and sediment present in the reach, however no issues
were observed. The greatest change since MY -03 is the presence of two obstructions,
located at stations 12 +80 and 13 +90, consisting of accumulated washed debris in the
channel. The obstructions are causing backwater effects that extend to the top of the
reach. The particle size distribution for the tributary has transitioned to a finer particle
bed material from MY -03 due to the backwater. The longitudinal profile and cross
sections for MY -04 show no significant changes from the previous monitoring year.
Summary information /data related to the occurrences of items such as beaver or
encroachment, and statistics related to performance of various project and monitoring
elements, can be found in the tables and figures in the report appendices. Narrative
background and supporting information formerly found in these reports can be found in
the mitigation plan and restoration plan documents available on EEPs website. All raw

request.
II. Methodology
Methodologies follow the current EEP monitoring report template, Version 1.3 1115110,
and the version 4.2 of the CVS -EEP protocol for recording vegetation (Lee et al 2008).
Photos were taken with a digital camera. A Trimble Geo XT handheld unit with sub -
meter accuracy was used to locate stream and vegetation problem areas.
A. Vegetation Methodologies
Level II of the EEP /CVS protocol Version 4.2, which includes natural stems, was used to
collect data for MY -04 for five vegetation monitoring plots. Data collected for these
plots are in Appendix C.
B. Stream Methodologies
Stream profile and cross - sections were surveyed using total station equipment and
methods. The survey data was plotted using AutoCAD Civil3D. The longitudinal profile
was generated using the MY -02 alignment. Cross sectional data was extracted based on a
linear alignment between the end pins. Pattern parameters were calculated by measuring
the plotted dimensions of the MY -04 surveyed thalweg. Profile parameters were
determined through analysis of a Microsoft Excel generated plot of the profile based on
the aforementioned baseline alignment.
