The project was transferred from NCDOT to the North Carolina Ecosystem Enhancement Program (NCEEP) in 2006. The following goals were established for the Back Creek Stream and Wetland Restoration Project. 1. Restore approximately 3,525 linear feet (If) of Back Creek. 2. Restore approximately 8271f of tributaries to Back Creek. 3. Restore approximately 1.5 acres (ac) of jurisdictional wetland, enhance approximately 1.8 ac of jurisdictional wetland, and create approximately 0.5 ac of open water/freshwater marsh adjacent to on-site channels. 4. Reforest approximately 17.5 ac of floodprone area and adjacent upland slopes with native forest species. The Back Creek project consisted of restoring approximately 1,300 if of the existing channel (Priority 1) and enhancing approximately 2,000 if (Priority 2/3) where restoration was not feasible. Approximately 775 if of two unnamed tributaries to Back Creek were also restored (Priority 1). Back Creek's riparian areas were planted to improve habitat and stabilize streambanks. The site contains 3.5 ac (proposed as 1.8) of wetland enhancement and 0.4 ac (proposed as 2.0) of wetland restoration. This report serves as the 3rd year of the 5 year • monitoring plan for the Back Creek Stream and Wetland Restoration Site. The 2008 vegetation monitoring results indicated that the Back Creek Site appears to be meeting vegetation success criteria. Vegetative monitoring success criteria, as stated in the 2003 NCDOT mitigation plan, requires an average number of planted stems per acre exceeding 320 stems per acre after the third year of monitoring. The survival rate for the woody vegetation monitored for 2008 is 69%. The site density is approximately 368 planted stems per acre with a plot size of 0.057 ac, which exceeds the year 3 goal of 320 planted stems per acre. A survivability increase from 2007 is most likely due to the resprouting of suspected dead stems recorded. Only one of the four vegetation monitoring plots (Plot 4) continues to result in a low survival rate (30%) with sparse ground cover of emergent wetland plants in comparison to the 2006 and 2007 monitoring year. Planted stem mortality within Plot 4 is most likely due to the severe drought experienced during the 2007 growing season. Results from the 2008 stream monitoring effort indicate that Back Creek and the two unnamed tributaries appear to be maintaining vertical and lateral stability with stable structures and minimal bank erosion. A few problem areas were observed, such as moderate bank erosion, moderate to poor streambank cover, loose matting, and aggradation. It is recommended that the section with poor streambank cover (approximate stationing 33+14 and 34+38) should be stabilized with matting and vegetation as soon as possible to prevent future problems. Areas with aggradation, such as lateral and transverse bars will be closely monitored for shifts in lateral stability. These areas of stream instability do not appear to have advanced from the previous Back Creek Monitoring Report - FINAL Jordan, Jones, & Goulding Project No. 17 March 2009 Year 3 of 5 Page 2 Executive Summary • 0 • monitoring years; however, it is suggested that these areas continue to be monitored closely for major shifts in bed features and the channel thalweg. For the 2008 monitoring year, all gauges achieved the wetland success criterion of soil saturation within the upper 12 inches for 30 consecutive days, which is 12.5 percent of the March 21 to November 16 (241 days) growing season. However for this monitoring report, hydrologic data is shown through September 30 due to report submittal due dates. The planted woody stem species throughout the wetland areas are meeting the required success criteria with the exception of plot 4. Overall, the Back Creek Stream and Wetland Restoration Site appears to be stable and has met the stream, vegetation, and wetland mitigation goals for monitoring year 3. Back Creek Monitoring Report - FINAL Project No. 17 Year 3 of 5 Jordan, Jones, & Goulding March 2009 • SECTION I PROJECT BACKGROUND • 0 • SECTION 1 PROJECT BACKGROUND The background information provided in this report is referenced from the mitigation plan and previous monitoring reports prepared by EcoScience (2003). 1.1 Location and Setting The Back Creek Site is located approximately five miles northeast of the City of Charlotte in Mecklenburg County, North Carolina. The site is east of Back Creek Church Road and southwest of the intersection of State Route 49 and Interstate 485 (Figure 1.1). The restoration site is located within the Piedmont eco-region and in the Yadkin-Peedee River Basin (USGS Subbasin HUC 03040105). The project site size is 17.5 ac. To access the site from Interstate 85, take Exit 48 (I-485S), follow to Exit 33 (Highway 49), and turn right onto Highway 49. Next, turn left onto Back Creek Church Road, and continue until the intersection with Back Creek. The restoration project is located downstream from Back Creek Church Road. 1.2 Mitigation Structure and Objectives Historically, the site was utilized for livestock grazing and agricultural hay production. • Currently, the site is dominated by fallow, successional fields and a few stands of isolated hardwood forests. Sewer line construction and past landuse are the apparent causes of stream instability due to dredging and straightening of the upstream reach. A prior stabilization attempt included using rip-rap on the channel banks. Urban development in the watershed has also contributed to the instability of Back Creek. The following goals were established for the Back Creek Stream and Wetland Restoration Project. 1. Restore approximately 3,525 if of Back Creek. 2. Restore approximately 8271f of tributaries to Back Creek. 3. Restore approximately 1.5 ac of jurisdictional wetland, enhance approximately 1.8 ac of jurisdictional wetland, and create approximately 0.5 ac of open water/freshwater marsh adjacent to on-site channels. 4. Reforest approximately 17.5 ac of floodprone area and adjacent upland slopes with native forest species. The stream and its tributaries were restored using a Priority 2 approach and enhanced using a Priority 2/3 where restoration was not feasible. Back Creek and the upstream tributary were designed and constructed as E-channels. The central tributary was designed and constructed as a B-channel. The project also included enhancing the associated riparian zone. According to the "Transfer of Back Creek Mitigation Site" letter from NCDOT to NCEEP dated March 15, 2006, • the mitigation site consists of approximately 4,075 (proposed as 4,352) if of restored stream Back Creek Monitoring Report - FINAL Jordan, Jones, & Goulding Project No. 17 March 2009 Year 3 of 5 1-2 Project Background including restoring approximately 3,300 (proposed as 3,525) if of Back Creek and restoring • approximately 775 (proposed as 827) if of tributaries to Back Creek. Also, per the previous referenced letter, the site contains 3.5 ac (proposed as 1.8) of wetland enhancement and 0.4 ac (proposed as 2.0) of wetland restoration. Construction of the restoration project was completed in December 2005, and tree planting was completed in February 2006. The Back Creek project consisted of restoring approximately 1,300 if of the existing channel (Priority 1) and enhancing approximately 2,000 if (Priority 2/3) where restoration was not feasible (Table 1.1). The relocated reaches and the restored in-place reaches were restored/enhanced using vegetation and in-stream stabilization structures, such as cross vanes, J- hook vanes, and grade control sills. Bankfull benches were created along each reach to re- establish floodplain connection. Approximately 775 if of two unnamed tributaries to Back Creek were also restored (Priority 1). The upstream tributary was designed and constructed as an E- channel and in-stream stabilization structures were installed. The central tributary was designed and constructed as a B-channel and step-pool structures were installed. Riparian areas were planted with native bare root seedlings and herbaceous cover to enhance the riparian areas and stabilize streambanks.

A total of seven cross-sections were established within the main reach of Back Creek and one cross-section was established within the upstream tributary in 2006. An additional cross-section was established within the central tributary during the 2007 monitoring year. Approximately 3,100 if of longitudinal profile were monitored. Four previously established vegetative plots in the riparian zone adjacent to Back Creek were identified and monitored. Photographs were taken upstream and downstream at each cross-section, vegetation plot, and at photo points that were established during the 2006 monitoring year. Back Creek Monitoring Report - FINAL Project No. 17 Year 3 of 5 Jordan, Jones, & Goulding March 2009 JJG • SECTION 2 PROJECT CONDITION AND MONITORING RESULTS • 0 SECTION 2 • PROJECT CONDITION AND MONITORING RESULTS The following monitoring results are from the 2008 (year 3 of 5) survey. 2.1 Vegetation Assessment 2.1.1 Soil Data Back Creek is situated within an agricultural valley in the inner Piedmont Belt of the North Carolina Piedmont Physiographic Province. Researchable data indicates that the soils within the project area are those found in alluvial landforms in this physiographic region; however, grading and filling activities during construction likely have disturbed the parent soil material. Review of the Soil Survey of Mecklenburg County, North Carolina indicates that three soil series are found within the project limits. These soil series consist of Monacan, Enon, and Wilkes. Monacan soils are very deep, well-drained to somewhat poorly-drained soils found along stream corridors. These soils are formed in recent alluvium sediments of the Piedmont and Coastal Plain. Slopes are generally less than 2 percent. Enon soils are very deep, well-drained soils on ridges and side slopes of the Piedmont uplands. The soils are formed in clayey residuum weathered from mafic or intermediate igneous and metamorphic rocks such as diorite, gabbro, gneiss, and schist of the Piedmont uplands. Slopes range from 2 to 15 percent for the Enon series. Wilkes soils are shallow, well-drained soils adjacent to drainage ways. They are formed in residuum weathered from intermediate and mafic crystalline rocks on the Piedmont uplands. Slopes range from 15 to 25 percent for the Wilkes series. Please refer to Table 2.1 for descriptions of the soil series within the project area. Table 2.1 Preliminary Soil Data Back Creek/Project No. 17 Series Max Depth in % Clay on Surface K Factor T Factor OM % Enon 72 5-20 0.24 5 0.0-2.0 Monacan 80 7-27 0.43 5 0.0-3.0 Wilkes 48 5-20 0.24 2 0.0-2.0 2.1.2 Vegetative Current Condition During the vegetative survey conducted in June 2008, it was noted that some areas of the streambanks have suffered localized loss of vegetative cover. In these areas, it is expected that flood events may have caused bank erosion; therefore, removing vegetation. Furthermore, the compaction of soil and nutrient poor conditions may also be contributing to the mortality of live . stakes and herbaceous cover in these areas. Please refer to Appendix 1.1 and 1.2 for more details on vegetative current condition areas and photos.

Vegetation assessments were conducted following the NCEEP 2004 Stem Counting Protocol which consists of counting woody stems within the established vegetation plots. The four vegetative plots previously established in the design phase were selected randomly and represent the riparian buffer zone. The planted vegetative community goal for these plots is to establish a Piedmont floodplain forest. Success goals for vegetation were established in the January 2003 mitigation plan prepared by EcoScience. The following lists the vegetation success criteria used for the Back Creek Stream and Wetland Restoration Site. 320 stems per acre years 1 through 3 290 stems per acre year 4 260 stems per acre year 5 Up to 10-percent of the stems per acre can include naturally recruited "character species." Character species are represented by those tree species that were planted on site. Trees planted within the monitored plots include swamp chestnut oak (Quercus michauxii), river birch (Betula nigra), American sycamore (Platanus occidentalis), green ash (Fraxinus pennsylvanica), and American elm (Ulmus americana). In addition, natural recruitment vegetation was also monitored within these plots. Naturally recruited species encountered were sweet gum (Liquidambar styraciflua) and red maple (Acer rubrum). The survival rate for the planted woody vegetation monitored for 2008 is 69%, which has remained the same from previous data recorded in September 2007. The monitoring data indicates an average of 21 stems per plot. Using an average of 21 stems per plot and a plot size of 0.057 acre, the average stem density for the site is 368 stems per acre. In addition, natural recruitment stems were also monitored. The monitoring data indicates an average of 9 volunteer stems per plot. Please refer to Appendix 1.1 for vegetation raw data. In conclusion, the riparian restoration project meets the success criteria requirements. Some loss of streambank vegetation was evident in 2006; however, the overall growth of the streambank vegetation is good and appears to have improved over the past few years. The overall success of the woody vegetation monitored within three of the four plots appears to be better than what was initially assessed in September 2006. This is most likely due to the resprouting of suspected dead saplings and new volunteer species. Although all plots met the vegetation success threshold with the exception of plot 4, the results from plot 4 did not affect the site's average survivability to be considered unsuccessful. In conclusion, the riparian restoration project meets the requirements per the success criterion for 2008 monitoring year.

The upstream and central tributaries were also evaluated through visual assessments, and cross-sectional surveys. Data collected from the previous monitoring year (MY 2006) was not used in the longitudinal profile comparison, because it was collected using a different type of engineering equipment, such as a site or laser level. Using different instrumentation to collect the morphological data affects the longitudinal stationing of the profile. As a result, conclusions drawn from this analysis are not completely representative of the actual changes occurring along the channel Back Creek Monitoring Report - FINAL Jordan, Jones, & Goulding Project No. 17 March 2009 Year 3 of 5 Page 2-4 Project Condition and Monitoring Results profile. The data collected in monitoring years 2007 and 2008 were chosen to represent the changes occurring within the longitudinal profile for the longitudinal graphical display because they are indicative of the actual morphological change that has occurred over the three year monitoring period. Please refer to Table 2.3 for a summary of the visual stability assessment, Table 2.4 for the monitoring baseline morphology and hydraulic summary, Table 2.5 for monitoring years 2006- 2008 morphology and hydraulic summary, Table 2.6 for hydrologic criteria, and Appendix 2 for more detailed stream data tables and plots. 2.2.1 Stream Current Condition Plan View Please refer to Appendix 4 for location of stream current condition on-site. 2.2.2 Stream Current Condition Table Please refer to Appendix 2.1 for the stream current condition table. 2.2.3 Numbered Issues Photo Section Please refer to Appendix 2.2 for representative stream current condition photos. 2.2.4 Fixed Photo Station Photos • Please refer to Appendix 2.3 for stream photo station photos and Appendix 2.4 for stream cross- section photos. 2.2.5 Stability Assessment The majority of the project conditions reflected the as-built drawings. The following general observations were noted. Main Channel The majority of project conditions continue to reflect the as-built drawings. The pattern, profile, and dimension of the restored channel appear stable. Please refer to the attached plan sheets and current condition table. A general overview is provided below. ¦ The pattern, profile, and dimension of the restored channel appear stable for the majority of the project. ¦ There are several areas with moderate erosion occurring under the matting. ¦ There are a few areas with eroding point bars on the upstream and downstream sides around stationing 3+30, 3+70, and 4+50. ¦ Three areas within the restored reach are illustrating signs of aggradation; two areas have lateral bars forming (approximate stationing 25+90 and 27+30), and the third area has a i Back Creek Monitoring Report - FINAL Jordan, Jones, & Goulding Project No. 17 March 2009 Year 3 of 5 Page 2-5 Project Condition and Monitoring Results transverse and mid channel bar forming (approximate stationing 14+90). All three areas show • a shift in the thalweg. ¦ Bank erosion is occurring at different levels throughout the channel, particularly where the lateral, transverse, and mid channel bars are forming and within the lower end of the project. ¦ The medium-sized cedar tree, which had fallen into the stream during the 2006 monitoring year, has remained in place below the convergence of the B channel. The tree has continued to collect storm debris. ¦ The two side tributaries appear stable with minor bank scour occurring. ¦ The majority of structures appear to be in good condition; however, a few structures have moderate erosion around the arms where they tie into the bankfull elevation. Overall, the present stream dimensions in Back Creek appear to be stable. The average bankfull width (30.15 ft) of the surveyed cross-sections is higher than the proposed 22.4 ft, and the average surveyed mean bankfull depth is 1.86 ft compared to the proposed 2.5 ft. The surveyed bankfull widths and depths lead to an average Width/Depth ratio of 16.45 and the sinuosity is 1.5. The W/D ratio (16.45) is typical of a C-type channel, but the sinuosity (1.5) is typical of an E-type channel. Therefore, due to these defining characteristics for this monitoring year, the stream classifies as an E4c. The average Width/Depth ratio has decreased since the 2006 monitoring year indicating that the channel is becoming more narrow and deep, which is typical for proposed E-type streams. Most likely this channel will continue to narrow and the W/D ratio over time will eventually be characterized as an E-type channel, thereby dropping the "little c" notation in the classification as well. • The 2008 substrate analysis illustrates that all of the cross-sections within the restoration site are showing a coarsening trend; therefore, recovering from the drought conditions experienced in 2007. JJG conducted a longitudinal profile along 3,100 if of Back Creek. The thalweg 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 similar for the surveyed reach, 0.0040 ft/ft and 0.0040 ft/ft, respectively. The surveyed water surface slope was slightly steeper than the proposed 0.0034 ft/ft, but similar to the 2006 and 2007 surveyed slopes. Overall, the reach appears to be maintaining vertical and lateral stability with stable structures and minimal bank erosion. Areas with aggradation, such as lateral and transverse bars, in the future could potentially be flushed out with higher flows. However, this may also be an indicator that the constructed pattern is adjusting within certain sections. If these areas continue to shift and aggrade they could potentially create significant lateral instability and shifts in the stream's pattern and profile. These areas have not advanced from the previous monitoring years, but will continue to be monitored closely for major shifts in bed features and the channel thalweg. Upstream Tributary Based on current monitoring data and the visual inspection, the channel seems to be functioning properly and maintaining stability. No erosion or structure failure was observed along this reach. 11 Back Creek Monitoring Report - FINAL Jordan, Jones, & Goulding Project No. 17 March 2009 Year 3 of 5 2-6 Project Condition and Monitoring Results • Central Tributary A visual assessment of stability was performed for the central tributary. The tributary appears to be maintaining its proposed function as a 13-type storm drain channel. There are some areas with moderate bank erosion, but no structural failure is occurring along this reach.

Two of these groundwater gauges were installed in close proximity to Vegetation Plot 2. One gauge is located within an emergent wetland area adjacent to the stream. The monitoring gauges are programmed to download groundwater levels daily and were downloaded monthly from March to October in order to capture hydrological data during the 2008 growing season. The target wetland hydrological success criterion is saturation Back Creek Monitoring Report - FINAL Project No. 17 Year 3 of 5 Jordan, Jones, & Goulding March 2009 Page 2-10 Project Condition and Monitoring Results or inundation for at least 12.5 percent of the growing season in the lower landscape (floodplain) • positions. To achieve the above hydrologic success criterion, groundwater levels must be within 12-inches of the ground surface for 30 consecutive days, which is 12.5 percent of the March 21 to November 16 (241 days) growing season. However, for this monitoring report hydrologic data is shown through September 30 due to report submittal due dates. 2.3.1 Wetland Current Condition Plan View There were no problem areas observed within the wetland restoration zones for the Back Creek Stream and Wetland Restoration Project. Within the wetland zones, hydrophytic vegetation and hydrology indicators have developed. In some areas, the appropriate soil chroma has also developed. It is suspected that these areas may have already had hydric conditions present. Hydrophytic vegetation consists of a thick herbaceous layer of sedge species (Carex spp.), rush species (Juncus spp.), bulrush species (Scirpus spp.), spotted touch-me-not (Impatiens capensis), and Smartweed species (Polygonum spp.). The planted woody stem species throughout the wetland areas are meeting the required success criteria; however, mortality of woody stems was observed. It is suspected that the mortality of planted stems may be subject to the planting technique or the soil conditions prior to planting. The general success of hydrology within the wetland restoration zones is adequate to meet success requirements. Surface inundation to ground saturation was observed throughout the site; therefore, appropriate hydrological condition for the wetland zones appears to be present. 2.3.2 Wetland Criteria Attainment • All gauges on site achieved the wetland success criterion of soil saturation within the upper 12 inches for 30 consecutive days during the growing season. Please refer to Appendix 3 for wetland raw data tables and plots and Table 2.7 for a summary of wetland criteria attainment.

A SECTION 3 METHODOLOGY 0 0 • • 3.1 Methodology SECTION 3 METHODOLOGY Methods employed for the Back Creek Stream and Wetland Restoration Project were a combination of those established by standard regulatory guidance and procedures documents as well as previous monitoring reports completed by EcoScience. 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.
