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 grazmg Page 2 of 40 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 Page 3 of 40 ow MITIGATION UNIT TOTALS Stream Mitigation Units SMU Restoration Segment/Reach Pre — Construction (acreage/linear feet Mitigation Approach Watershed Acreage As -Built Linear Footage /Acreage Mitigation Ratio Mitigation Units (SMU/WMU) STREAM ; x a1-�.� _ •� .r ,.a..*bi2^,yr� }La _ 4, ,•.. „r_w,, -t„, . .c�' 2_ ,...F, Reach I- Ellington 1575.0 R 0.8 sq. mi. 1934 1.0 1934 Branch Reach II- Ellington 2475.9 R 1.1 sq. mi. 1801 1.0 1801 Branch Reach III -

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 Ellington State of Virginia Branch VAN CE N.
