Report February 2011 EEP Project No 17 Momtormg Year 5 of 5 SECTION 1 EXECUTIVE SUMMARY SECTION 1 EXECUTIVE SUMMARY The Back Creek Stream and Wetland Restoration Project (Site) is a 17 5 acre lot located in Mecklenburg County, North Carolina, northeast of the City of Charlotte (Appendix 1 1) Back Creek drams approximately 4 square rules and is located within the Piedmont Ecoregion in the Yadkin- Peedee River Basin (USGS HUC 03040105) The Site is a mitigation project for the North Carolina Department of Transportation ( NCDOT) The project was transferred from NCDOT to the North Carolina Ecosystem Enhancement Program (NCEEP) in 2006 Construction of the restoration project was completed in December 2005, and tree planting was completed in February 2006 This report serves as year five of the five year monitoring plan for the Site 1.1 Goals 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 land use have impaired the streams stability due to dredging and straightening of the upstream reach Urban development in the watershed has also contributed to the instability of the Site The following goals were established for the Site 1 Restore approximately 3,525 linear feet (If) of Back Creek 2 Restore approximately 827 if 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 flood prone area and adjacent upland slopes with native forest species TABLE 1 PROJECT TOTALS Footage Creditable Footage +_ Main stem 3371 feet 3251 feet* Upper tributary 411 feet 411 feet Central tributary 354 feet 304 feet* 4136 feet 3966 feet *The differences between the creditable footage and the footage have to do with a 120 foot length of the main stem that is within the 1485 ROW, effectively making a single sided easement and therefore not creditable The central tributary has —50 feet in the same situation Back Creek Monitoring Report February 2011 EEP Project No 17 Monitoring Year 5 of 5 Pate 1 -2 Executive Summary The site also contains 3 5 ac (proposed as 1 8 ac) of wetland enhancement and 0 4 ac (proposed as 2 0 ac) of wetland restoration Appendix 2 provides more detailed project activity, history, contact information, and watershed/site background information for this project 1.2 Vegetative Assessment JJG conducted the 2010 (year 5 of 5) vegetative assessment and vegetative plot analysis in October 2010 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 The following success criteria for vegetation were established for the Site by EcoScience (2003) ■ 320 stems per acre years 1 through 3 ■ 290 stems per acre year 4 ■ 260 stems per acre year 5 Vegetation problem areas previously noted along the streambanks that had suffered localized loss of vegetative cover appear to re- stabilizing In these areas, it is assumed that flood events may have caused bank erosion, therefore, removing vegetation in previous monitoring years Most of these problem areas have either fully recovered or are continuing to improve with each growing season The 2010 vegetation monitoring results indicate that the Site appears to be meeting vegetation success criteria with the exception of Plot 4 The Site's average stem density is approximately 364 planted stems per acre with a plot size of 0 057 ac, which exceeds the year 5 goal of 260 planted stems per acre Only one of the four vegetation monitoring plots (Plot 4) continues to result in a low survival rate Initially, planted stem mortality within Plot 4 was most hkely due to the severe drought experienced during the 2007 growing season During the recent growing seasons, volunteer species and resprouting of suspected dead saplings have increased the stems per acre for Plot 4 For the 2010 monitoring year, Plot 4 resulting in a stem density increase due to volunteer species from 140 stems per acre to 404 stems per acre, which meets success criteria for the year 5 goal In conclusion, the Site has met the vegetation success criteria requirements for monitoring year five (2010) Some loss of streambank vegetation was evident in 2006, however, the overall growth of the streambank vegetation is good and continues to improve as seen over the past few monitoring years The overall success of the woody vegetation momtored 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 planted stem density to be considered unsuccessful Please refer to Appendix 12 and 3 for detailed information regarding the 2010 vegetation current conditions and monitoring data results Back Creek Monitoring Report February 2011 EEP Project No 17 Monitoring Year 5 of 5 Page 1 -3 Executive Summary 1.3 Stream Assessment A total of nine cross - sections were established along Back Creek, seven were established along the main channel and one cross - section was established along both the upstream tributary and the central tributary Stream dimension, profile, and substrate were evaluated along 3,100 if of the main channel The upstream and central tributaries were evaluated through visual assessments and cross - sectional surveys Main Channel The pattern, profile, and dimension of the restored channel appear stable for the majority of the project The structures appear to be in good condition, however, a few structures have moderate scour around the vane arms where they tie into the bankfull elevation Instances of localized bank scour occurred earlier in the monitoring history and were scattered across the site but generally did not advance, with bank stability percentages at or above 95% for the project's monitoring history A few of these areas were severe and associated with some mid and transverse bars that subsequently flushed out of the system Vegetation growth has improved in these areas and is further stabilizing previous bank scour Within these areas, vegetation growth has unproved, which is stabilizing the banks One (1) area within the restored reach is still illustrating signs of aggradation (approximate stationing 19 +93), but there has been little to no changes occurring in the past few monitoring years The average bankfull width (26 61 ft) of the surveyed cross - sections is higher than the proposed 22 4 ft but continues to illustrate a narrowing trend in comparison to the average bankfull width in 2006 (32 40 ft) The average surveyed mean bankfull depth is 2 02 ft compared to the proposed 2 5 ft, however, in comparison to the average mean depth in 2006 (1 89 ft), the Site's average cross - sectional depth continues to increase The surveyed bankfull widths and depths lead to an average Width/Depth (W/D) ratio of 16 24, and the sinuosity is 1 5 The W/D ratio (16 24) 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 the 2010 monitoring year, the stream was classified as an E4c The average W/D ratio (13 65) has decreased since the 2006 monitoring year (18 52) indicating that the channel is becoming more narrow and deep, which is typical for E -type streams The 2010 substrate analysis illustrates that all of the cross - sections within the restoration site are recovering from the drought conditions and beaver activity experienced in previous monitoring years 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 the same for the surveyed reach, 0 0040 ft/ft The surveyed water surface slope was slightly steeper than the proposed 0 0034 ft /ft, but similar to the previous monitoring year surveyed slopes A crest gauge is located downstream of cross - section 6 within the Back Creek project site One bankfull or greater event occurred within the Back Creek restoration project in monitoring year 2010 Other indicators such as old wrack Imes and staining were observed at the bankfull and greater elevations within the restoration site as well Back Creek Monitoring Report February 2011 EEP Project No 17 Monitoring Year 5 of 5 Page 1 -4 Executive Summary 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 Central Tributary The tributary appears to be maintaining its proposed function as a B -type storm drain channel There are some areas with minor bank erosion, but no structural failure is occurring along this reach Cross - section 9, which is located midway along the tributary has remained vertically and laterally stable Minor sediment deposition occurred in 2010, which resulted in a decrease in the cross - sections mean depth (1 04 ft) from previous monitoring year ranges (124-1 32 ft) The d50 and d84 particle size has decreased from 0 33 mm to 0 2 mm and 3 43 to 1 67, respectively Most likely, these fine particles will be flushed with future ram events Overall, the Site appears to be maintaining vertical and lateral stability with stable structures and minimal bank erosion A few of the areas with aggradation, such as lateral and transverse bars, have adjusted from previous monitoring year As a result of being flushed out with higher flows, these depositional areas have not advanced from the previous monitoring years Please refer to Appendix 4 for detailed stream data tables and plots and Appendix 12 for the location of the monitoring features 1.4 Wetland Assessment Three groundwater monitoring gauges and one ram gauge were installed on -site 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 main channel The monitoring gauges are programmed to download groundwater levels daily and were downloaded monthly from March to November in order to capture hydrological data during the 2010 growing season The target wetland hydrological success criterion is saturation 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 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 There were no problem areas observed within the wetland restoration zones for the Site 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 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 Please refer to Appendix 5 for wetland plots and a summary of the wetland criteria attainment Back Creek Monitoring Report February 2011 EEP Project No 17 Monitoring Year 5 of 5 Page 1 -5 Executive Summary 1.5 Annual Monitoring Summary In summary, the Site has met the stream, vegetation, and wetland mitigation goals for monitoring year 5 The 2010 vegetation plot monitoring results indicate that the planted and naturally recruited vegetation is doing well at the Site, although some minor vegetation problems were noted due to the severe drought experienced during the 2007 growing season The pattern, profile, and dimension of the restored channel 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 These areas of stream instability do not appear to have advanced from the previous monitoring years For the 2010 monitoring year, all gauges achieved the wetland success criterion of soil saturation within the upper 12 inches for 30 consecutive days The background information provided in this report is referenced from the mitigation plan and previous monitoring reports prepared by EcoScience (2003) Summary mformation/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 ESP's website All raw data supporting the tables and figures in the appendices is available from EEP upon request Back Creek Monitoring Report February 2011 EEP Project No 17 Monitoring Year 5 of 5 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 procedure 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 Precipitation data for the hydrographs was obtained from an off -site resource in Concord, NC weather station (the nearest station offering daily precipitation data) through Weather Underground URL (http //www wunderground com/history
