Project Setting and Background Summary
Sungate Design Group, PA (Sungate) entered into a full delivery contract with the NC Department of Environment and Natural Resources, Ecosystem
Enhancement Program (EEP) on June 21, 2006 to provide 5,000 Stream Mitigation Units (SMUs) in the Roanoke River Basin The Ellington Branch Stream
Restoration Site, hereinafter referred to as the "Project Site," was selected to meet these overall obligations Ecological Engineering, LLP (Ecological Engineering)
is under contract with Sungate to perform the remaining monitoring requirements The Project Site is situated in Warren County, North Carolina and includes a
portion of Ellington Branch and one of its unnamed tributaries Ellington Branch is a second order, perennial stream originating approximately one half mile
upstream (south) of the project area The unnamed tributary (UT) is a first order, perennial stream that converges with Ellington Branch from the west The project
was identified by Sungate in 2005 and selected for full delivery restoration by EEP based its location, attributes, existing condition and overall likelihood for
success
Based on the MY 5 surveys, all plots exhibited surviving planted and transplanted species in excess of 324 planted stems per acre The Project Site has met and
exceeded the established success criteria for vegetation based on the survival of the planted species for Year 5 monitoring
Stream restoration success criteria for the two restored stream reaches were also met during the MY 5 monitoring assessment No significant changes to the
dimension, pattern, and profile or bed material were observed Location surveys of the constructed features were conducted to verify the performance of both
channels Surveys were performed to compare the six previously determined stream longitudinal profiles and the 23 permanent stream cross - sections with as -built
and Year 1 through Year 4 monitoring data A modified Wolman pebble count and assessment of the constructed features was also undertaken as part of Year 5
monitoring efforts
Based on the interpreted data, both Ellington Branch and its UT remain stable All of the structures are functioning as designed and bank erosion is non - existent
Drought conditions present during 2008, 2009 and 2011 continue to be factor effecting sediment transport at the Project Site Ellington Branch was dry for the first
half of 2008 while the UT maintained only a trickle of water The same scenario occurred during the early summer months of 2009, particularly June and July
Portions of Ellington Branch were dry again during the summer of 2011 As a result, wetland and streamside vegetation became established throughout portions of
the bankfull channel area This was very beneficial to streambank stabilization although possibly detrimental to sediment transport Ecological Engineering closely
monitored the effects of vegetation throughout these areas throughout the fall and winter of 2012 No adverse effects were observed
Goals and Objectives
The goals and objectives of the project were to ultimately create a continuous wooded stream corridor by restoring and revegetating the largest reach of disturbed
channel and buffer along Ellington Branch This in turn, would also improve the overall function and habitat associated with the stream channel and riparian areas
Sungate's restoration plan included restoration (including dimension, pattern and profile) of Ellington Branch and its UT, as well as the establishment and
restoration of an active riparian buffer complex In addition, the goals and objectives were also to restore the primary stream and buffer functions and values
associated with nutrient removal and transformation, sediment reduction and retention, flood -flow attenuation, and wildlife (both aquatic and terrestrial) habitat
The Site provided an excellent opportunity to restore and preserve a substantial riparian zone on lands that were currently being utilized for pasture and cattle

Success Criteria
Performance criteria set forth for this project will be provided according to EEP's monitoring criteria and format, dated 2005 It covers both stream and vegetation
assessments and is based according to federal guidelines for stream mitigation, including the following main parameters no less than two bankfull events for the
five year monitoring period, reference photos, plant survival analyses, and channel stability analyses Biological data is not required as part of the contract
Photographs will depict the annual progress of the project Tables will be provided documenting stability and quantitative summary data All of this information
will be summarized and combined with the vegetation information in an annual report
Natural streams are dynamic systems that are in a constant state of change Longitudinal profile and cross section surveys may differ somewhat from year to year
Natural channel stability is achieved by allowing the stream to develop a proper dimension, pattern, and profile such that, over time, channel features are
maintained and the stream system neither aggrades nor degrades A stable stream consistently transports its sediment load, however, there may be local deposition
and scour Channel instability occurs when the scouring process leads to degradation, or excessive sediment deposition results in aggradation
Vegetation requirements for mitigation purposes state that 320 stems /acre must be viable for success after the three year monitoring period, 288 stems /acre must be
viable for the four year monitoring period and 260 stems /acre for the five year monitoring period This accounts for a ten percent yearly acceptance The vegetation
will be assessed using individual stem counts within strategically placed 10 -meter by 10 -meter plots Sungate established a total of 13 vegetation plots along
Ellington Branch and its UT The plot locations were determined prior to planting and are shown on the as -built plans Annual photographs will document growth
and succession

APPENDIX A: Watershed Summary
Ellington Branch Stream Restoration Project
The Ellington Branch stream restoration project is located in Warren County, approximately 12
miles northeast of the town of Henderson in the Roanoke River Basin It is located within HUC
03 01010603 1010, the Smith Creek watershed, which is listed as a Targeted Local Watershed
(TLW) in the 2009 Roanoke River Basin Restoration Priorities (RBRP) plan, as well as in the
previous 2001 RBRP (http: / /portal.ncdenr org/web /eep /rbrps /roanoke) Currently, the EEP has
no other projects in this TLW
Ellington Branch flows into Smith Creek roughly 4 miles downstream of the project site, which
eventually empties into Lake Gaston just over the Virginia border The 2009 RBRP indicates
that Smith Creek is an NC 303(d) listed impaired water due to poor benthic macro - invertebrate
communities and for only partially supporting aquatic life It also states that Smith Creek has a
streambed composed almost entirely of sand and notes high turbidity and evidence of stream
scouring during high flows There was also a gradual increase in conductivity observed in the
stream during the last 15 years, and dissolved oxygen concentrations continue to be a concern.
There are no High Quality Waters (HQWs) or Outstanding Resource Waters (ORWs) found in
this TLW, nor are there any Significant Natural Heritage Areas (SNHAs), Natural Heritage
Element Occurrences (NHEOs), or protected Conservation Area The TLW area is 34%
agricultural with 18 permitted animal operations present The 2009 RBRP attributed pollution to
nonpoint sources and focused restoration priorities on agricultural BMPs and riparian buffer
projects that would reduce agricultural nonpoint source impacts to the watershed
The project involves stream restoration along both Ellington Branch and one of its unnamed
tributaries This tributary connects a 2 5 acre farm pond to the main channel Prior to the
restoration, the site was an incised stream with very degraded side banks and little -to -no buffer
located within and along the pasture fields of a cattle farm. The project improves aquatic fauna
habitat through the establishment of functional riffles, rock/log vanes, and pools It also restores
stream floodplain and established cattle exclusion fencing on both sides of the entire stream
network The establishment of a riparian buffer, the exclusion of cattle, and the re- connection of
the stream to a floodplain all serve to increase stream stability and nutrient removal capacity and
reduce sediment loss, thereby reducing the volume of pollutants flowing downstream into the
designated 303(d) impaired waters of Smith Creek
