The Site drains approximately 3.15 square miles to the Rocky River, within the Southern Outer Piedmont Physiographic Region of the Yadkin River Basin (HUC 3040105). The Site consisted of bank stabilization and habitat enhancement along 783 linear feet of Goose Creels. This project was conducted as a partial fulfillment of the off -site stream mitigation agreement between North Carolina Department of Transportation (NCDOT) and North Carolina Wildlife Resource Commission (NCWRC) for the I -485 outer loop project. The Site was constructed in February 2005 and transferred to EEP in 2007 for monitoring. This report serves as the second year of the five year monitoring plan for the Site. 1.1 Goals and Objectives The Site runs through small farms containing pastures, forested areas, and housing and commercial developments. The construction of I -485 has resulted in a shift from a rural to an urban land -use watershed. Poor riparian zone management in the upstream reaches of the watershed due to land disturbing activities such as clearcutting, overgrazing of streambanks, channelization, and development have had an adverse effect on the stability of the streambanks, in- stream habitat, and water quality. The Goose Creek watershed is one of two remaining North Carolina habitats of the federally endangered Carolina Heelsplitter mussel (Lasmigona decorate). As a result of concern for this species, the entire Rocky River watershed was designated as a priority area for conservation and protection. The following goals were established for the Site. 1. Enhance 783 linear feet of Goose Creels by grading banks, planting a riparian buffer, and reducing bank erosion. 2. Enhance the riparian zone adjacent to the stream with native forest species. 3. Restore degraded in- stream habitat via in- stream structures such as log and rock vanes. Streambanks and riparian areas were stabilized using bare -root plantings and temporary and permanent seed mixes. The Site was planted with native riparian vegetation. Enhancement of the stream areas will help to improve streambank stability, water quality, and increase local vegetative biodiversity. Appendix 2 provides detailed project activity, history, contact information, and watershed /site background for this project. 1.2 Vegetative Assessment Due to the lapse in time between construction and the first monitoring year, the vegetation plots previously established following construction in 2005 were not marked well enough to be located and assessed in 2009. Therefore, JJG established three new vegetation monitoring plots Goose Creek (Greene Mitigation) Monitoring Report March 2011 EEP Project No. 92709 Monitoring Year 2 of 5 Paae 1 -2 Executive Summary 100 m2 (two 5m x 20m and one 10m x 10m) in size on -site within the enhancement areas in the approximate location of the original plots established by NCWRC. Planted stems were determined to be planted or volunteer in 2009 since the original flagging was missing. The largest trees were recorded as the planted specimens and the smaller stems were recorded as natural recruitment. Vegetation assessments were conducted following the NCEEP 2004 Stem Counting Protocol which consists of counting woody stems within the established vegetation plots. The vegetation success criteria stated in the mitigation plan calls for a total of 256 stems per acre at the end of year three based on approximately 0.8 acres of land that was disturbed during construction. However, since JJG re- established 3 vegetation plots (0.0247 acres) in lieu of monitoring the previous plots due to the reasons previously stated, the following planted stems per acre requirements will be followed to determine vegetation success at the end of each monitoring year (USACE, 2003). ■ 320 stems per acre years 1 through 3 ■ 288 stems per acre year 4 ■ 260 stems per acre year 5 All the vegetation plots met the vegetation success threshold for the 2010 monitoring year (MY- 2). The 2010 vegetation monitoring indicated an average survivability of 1,592 planted stems per acre with a mean of 5,263 stems per acre when including volunteers. The number of planted species ranged from 8 -14 across plots with 14 -21 when including volunteers. MY -2009 was the first year of monitoring for the planted vegetation; however, the Site was planted in 2005 and therefore is in the fourth growing season. The monitoring data indicates an average of 39 stems per plot. In conclusion, the riparian restoration project meets the requirements per the success criterion for the 2010 monitoring year. Please refer to Appendix 3 for vegetation photos and raw data tables. 1.3 Stream Assessment Results from the 2010 stream monitoring effort indicate that stream pattern, profile, and dimension of Goose Creek is maintaining vertical and lateral stability with minimal problem areas. Areas along the stream enhancement reach noted with bare banks appear to be stabilized by the roots of larger trees established on the banks. These areas will continue to be monitored closely for significant adjustments in the bank, bed features, and channel thalweg. Stream dimension, pattern, profile, and substrate were evaluated within 688 linear feet of the Site. The average bankfull width (34.08 ft) of the surveyed cross - sections is within the range of the as -built widths reported (32 -44 ft), and the average surveyed mean bankfull depth is 3.2 ft compared to the as -built typical (2.9 ft). The surveyed bankfull widths and depths lead to an average Width/Depth ratio of 11.25 and a sinuosity of 1.2, which typifies a Rosgen C/E -type stream. The upper section of the enhancement project was classified as a 134c and the lower section of the project was classified as a C4e. The channel's profile appears to be stable, and was characterized by well - defined riffle and pool features. The average water surface slope and the average bankfull slope were the same for the surveyed reach, 0.0060 ft /ft. The substrate analysis illustrated a diverse and stable substrate material and available habitat with little to no deposition of fine substrate occurring. Goose Creek (Greene Mitigation) Monitoring Report March 2011 EEP Project No. 92709 Monitoring Year 2 of 5 1 -3 Executive Summary Near station 4 +00 feet (ft), a debris jam that has formed has temporarily affected the profile. This change in the profile is not a significant change that appears to be permanent. The debris jam and accumulated sediment will probably be flushed out of the system with future rain events. Other areas that are being watched include a stressed boulder toe with dislodged boulders and a failed structure at the end of the project that is no longer providing adequate bank protection. This structure is not providing the intended protection as it has become dislodged, and the neighboring bank has exhibited bank erosion. The structure may need to be removed. A crest gauge is not located on -site; therefore, JJG referenced a local USGS gauge (station 0212467451) located downstream of the Site with a similar drainage area (8.5 sq.mi.) to determine bankfull event occurrences. According to the USGS gauge, more than one bankfull event or greater was recorded within the Goose Creek watershed during the 2010 monitoring year. Other indicators such as old wrack lines and staining were observed at the bankfull and greater elevations within the Site. Overall, the Site appears to be maintaining vertical and lateral stability with minimal bank erosion and has met the success criteria for MY -2010. Please refer to Appendix 4 for detailed stream data tables and plots and Appendix 1.2 for the location of the longitudinal profile stations, cross - section stations, vegetation plots, photo points, and gauges. 1.4 Annual Monitoring Summary In summary, the Site has met the stream and vegetation mitigation goals for monitoring year 2. The 2010 vegetation plot monitoring results indicate that the planted and naturally recruited vegetation is doing well at the site. The pattern, profile, and dimension of the enhancement channel appear to be maintaining vertical and lateral stability with minimal bank erosion. A few problem areas were observed, such as poor streambank cover, minor structure instability and the debris jam mentioned above. However, these areas of stream instability do not appear to be advancing and have roots from larger trees growing along the bank that are providing bank stability. These areas will continue to be monitored closely for shifts in stability. The background information provided in this report is referenced from the mitigation plan prepared by NCWRC (2005). Summary information/data related to the occurrence 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 and restoration plan documents available on EEP's website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. Goose Creek (Greene Mitigation) Monitoring Report March 2011 EEP Project No. 92709 Monitoring Year 2 of 5 J�9 SECTION 2 METHODOLOGY SECTION 2 METHODOLOGY 2.1 Methodology Methods employed for the Site were a combination of those established by standard regulatory guidance and procedures documents as well as previous monitoring reports completed by NCWRC. Geomorphic and stream assessments were performed following guidelines outlined in the Stream Channel Reference Sites: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration a Natural Channel Design Handbook (Doll et al, 2003). Vegetation assessments were conducted following the NCEEP 2004 Stem Counting Protocol which consists of counting woody stems within the established vegetation plots. JJG used the Flora of the Carolinas, Virginia, Georgia, and surrounding areas by Alan S. Weakley as the taxonomic standard for vegetation nomenclature for this report. Off -site bankfull events were documented using the USGS station 0212467451, Goose Creek at SR 1524 near Indian Trail, NC.
