The Underwood Mitigation Site, hereafter referred to as the Site, consists of two separate areas (Harris Site and Lindley Site) located in western Chatham County within the Cape Fear River Basin (USGS Hydrologic Unit 03030002) north of Siler City, North Carolina The Harris site is located within the upstream area of the project watershed along Clyde Underwood Road, Just west of Planfield Church Road The Lindley Site is located downstream from the Harris Site, southwest of Moon Lindley Road between Johnny Lindley Road and Bob Clark Road The Site is located within the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998) Approximately 60% of the land in the project watershed is forest, 39% is classified as managed herbaceous cover or agricultural, and the remaining 1% is split between unmanaged herbaceous and open water (MRLC, 2001) The drainage areas for the Harris Site and Lindley Site are 1,051 acres (1 64 square miles) and 3,362 acres (5 25 square miles) respectively The project stream reaches consist of SF1, SF3, SF4, SF4A, UT1, and UT2 (stream restoration and /or enhancement level 1 approach) and SF2, SF3, UT1, UT1A, and UT1B (enhancement level II approach) Mitigation work within the Site included restoring and enhancing 9,133 linear feet (LF) of perennial and 7 intermittent stream channel and restoring, enhancing, and creating 13 84 acres of riparian and non- riparian wetland The stream and wetland areas were also planted with native vegetation to improve habitat and protect water quality Construction activities were completed by Land Mechanics Designs, Inc in November 2012 Planting and seeding activities were completed by Bruton Natural Systems, Inc in January 2013 Four separate conservation easements have been recorded and are in place along the riparian corridors and stream resources to protect them in perpetuity, 7 68 acres (Deed Book 1578, Page -- 495) within the tract owned by Mary Jean Harris, 18 44 acres (Deed Book 1578, Page 507) within the tract owned by William Darrel Harris, 5 34 acres property (Deed Book 1579, Page 1067) within the tract owned by James Randall Lindley, and 6 29 acres property (Deed Book 716, Page 707) within the tract owned by Jonathan Marshall Lindley Directions and a map of the Site are provided in Figure 1 and project components are illustrated for the Site in Figures 2a and 2b t� 11 Project Goals and Objectives j` Prior to construction activities, the streams and wetlands on the Harris Site were impacted by cattle grazing, which led to stream bank erosion and instability The Lindley site was used for row crop agriculture and the streams were straightened and deepened and much of the riparian vegetation was removed Related degradation includes declining aquatic habitat, loss of forest, degraded riparian buffers, loss of wetlands, and water quality problems related to increased sediment and nutrient loadings Table 4 in Appendix 1 and Tables 10a, 10b, and 10c in Appendix 4 present the pre - restoration conditions in detail The Underwood Mitigation Site was designed to meet the over - arching goals as described in the mitigation plan (2011) The project addresses multiple watershed stressors that have been documented for both the Cane Creek and Jordan Lake watersheds While many of these benefits are limited to the Underwood Site project area, others, such as pollutant removal and improved aquatic and terrestrial ! habitat, have more far - reaching effects The following project specific goals established in the -' mitigation plan include • Restore and stabilize stream dimensions, pattern, and profile, • Establish proper substrate distribution throughout restored and enhanced streams, Underwood Mitigation Site Monitoring Year 1 Annual Report —FINAL Page 1 • Improve aquatic and benthic habitat, • Reduce nutrient loads within the watershed and to downstream waters, • Further improve water quality within the watershed through reductions of sediment, ! bacteria, and other pollutants, • Decrease water temperature and increase dissolved oxygen concentrations, • Establish appropriate hydrology for wetland areas, • Restore native vegetation to wetlands and riparian buffers /improve existing buffers, and • Create appropriate terrestrial habitat The design features of this project were developed to achieve multiple project objectives The stream restoration elements were designed to frequently flood the reconnected floodplain and adjacent riparian wetlands This design approach provides more frequent dissipation of energy from higher flows (bankfull and above) to improve channel stability, provide water quality treatment through detention, settling, and biological removal of pollutants, and restore a more natural hydrologic regime Existing, restored, and created wetlands were key components of the design incorporated to better meet goals described above The project objectives defined in the mitigation plan (2011) are as follows • Construct stream channels that will remain relatively stable over time and adequately transport their sediment loads without significant erosion or aggradation, • Construct stream channels that maintain riffles with coarse bed material and pools with finer bed material, • Provide aquatic and benthic habitat diversity in the form of pools, riffles, woody debris, and in- stream structures, • Add riffle features and structures and riparian vegetation to decrease water temperatures and increase dissolved oxygen to improve water quality, • Construct stream reaches so that floodplains and wetlands are frequently flooded to provide energy dissipation, detain and treat flood flows, and create a more natural hydrologic regime, • Construct fencing to keep livestock out of the streams, - • Raise local groundwater table through raising stream beds and removing agricultural drainage features, • Grade wetland creation areas as necessary to promote wetland hydrology, and • Plant native tree species to establish appropriate wetland and floodplain communities and retain existing, native trees were possible The design streams and wetlands were restored to the appropriate type based on the surrounding landscape, climate, and natural vegetation communities but also with strong consideration to existing watershed conditions and trajectory The mitigation project corrected incision and lack of pattern caused by channelization, bank instability caused by erosion and livestock access, lack of vegetation in riparian zones, lack of riparian and aquatic habitat, and depletion of hydrology for adjacent wetlands The final mitigation plan was submitted and accepted by the NCEEP in September of 2011 Construction activities were completed by Land Mechanics Designs, Inc in November 2012 Planting and seeding activities were completed by Bruton Natural Systems, Inc in January 2013 Baseline monitoring (MY -0) was conducted between December 2012 and February of 2013 Annual monitoring will be conducted for five years with the close -out anticipated to commence in 2018 given the success criteria are met Appendix 1 provides more detailed project activity, history, contact information, and watershed /site background information for this project j ON Underwood Mitigation Site Monitoring Year 1 Annual Report—FINAL Page 2 12 Monitoring Year 1 Data Assessment Annual monitoring and quarterly site visits were conducted during monitoring year 1 (MY -1) to assess the condition of the project The stream and wetland mitigation success criteria for the Site follow the approved success criteria presented in the Underwood Mitigation Plan (5/7/2013) 12 1 Vegetative Assessment Planted woody vegetation is being monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey -NCEEP Level 2 Protocol (Lee et al , 2006) A total of 42 vegetation plots were established during the baseline monitoring within the project easement areas (29 at the Harris Site, 13 at the Lindley Site) using a standard 10 meter by 10 meter plot The final vegetative success criteria will be the survival of 260 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of year five of the monitoring period The interim measure of vegetative success for the Site will be the survival of at least 320 planted stems per acre at the end of year three of the monitoring period The MY -1 vegetative survey was completed in September 2013 The 2013 annual vegetation monitoring resulted in an average stem density of 605 stems per acre, which is greater than the interim requirement of 320 stems /acre, but approximately 15% less than the baseline density recorded (712 stems /acre) in January 2013 There is an average of 9 stems per plot which has remained the same since MY -0 A total of 38 out of 40 plots are on track to meet the success ` ! criteria required for MY -5 (Table 9, Appendix 3) Although two plots are not meeting success criteria, supplemental plantings will not be installed prior to the MY -2 survey Wildlands has observed on other mitigation sites that bare roots which appear to be dead during the MY -1 survey j may re- sprout in subsequent monitoring years The bare roots planted in MY -0 can also be difficult to re- locate during the MY -1 survey where there is dense herbaceous cover Following MY -2, Wildlands will re- evaluate low stem densities within the Site and conducted supplemental planting as needed Please refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables 1 2 2 Stream Assessment Morphological surveys for the MY -1 were conducted in August and September 2013 With the exception of SMA, all streams within the Site are stable with little to no erosion and have met the success criteria for MY -1 Please refer to Appendix 2 for the visual assessment table, Current condition plan view (CCPV), and reference photographs Refer to Appendix 4 for the morphological data and plots In general cross - sections show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio Surveyed riffle cross - sections fell within the parameters defined for channels of the appropriate Rosgen stream type The surveyed longitudinal profile data for SF1, UT2, SF3, UT1, and SF4 illustrates that the bedform features are maintaining lateral and vertical stability The riffles are remaining steeper and shallower than the pools, while the pools are remaining deeper than the riffles and maintaining flat water surface slopes The longitudinal profiles show that the bank height ratios remain very near to 10 for the restoration reaches Degradation was documented in the upper portion of SMA (approximate STA 900 +00 - 905 +33) In this section the stream has downcut up to 0 5 ft in some locations Although the adjustments in SMA's profile were not intended in the design, the stream is maintaining a stable bedform at a lower elevation SF4A will be closely monitored over the upcoming MY -2 degradation advancement If during MY -2 Oft Underwood Mitigation Site Monitoring Year 1 Annual Report—FINAL Page 3 degradation continues along SMA, Wildlands will prepare a maintenance plan to address the problem areas Details regarding the tentative maintenance plan are discussed below in section 1 2 3 Pattern data will be collected in MY -5 only if there are indicators from the profile or dimensions that significant geomorphic adjustments have occurred No changes were observed during MY -1 that indicated a change in the radius of curvature or channel belt width 1 2 3 Hydrology Assessment At the end of the five year monitoring period, two or more bankfull events must have occured in separate years within the restoration reaches Additional bankfull events were recorded on all the streams except for UT2 with crest gages during the MY -1 data collection Bankfull events have also been observed on UT1, SF2, SF3, SF4, and SF4A shortly after completion of construction These bankfull events occurred prior to the installation of crest gages, but were evidenced by wrack lines Please refer to Appendix 5 for hydrologic data 1 2 4 Maintenance Plan No maintenance plan is necessary at this time Wildlands will continue to monitor SMA and will develop a maintenance plan if it becomes apparent that the stream continues to downcut or otherwise destabilize A maintenance plan to correct this problem would likely consist of installation of sills at the downstream end of riffles to stabilize those features, add additional grade control, and backfill over time to raise the bed through the riffle sections 1 2 5 Wetland Assessment Fifteen groundwater monitoring gages were established during the baseline monitoring within the wetland restoration, creation, and enhancement zones The gages were installed at appropriate locations so that the data collected will provide an indication of groundwater levels throughout the site To provide data for the determination of the growing season for the wetland areas, two soil temperature loggers were installed in representative areas within RW3 and RW4 A barrotroll logger (to measure barometric pressure used in the calculations of groundwater levels with well transducer data) and a rain gage were also installed within the wetland areas on both the Harris and Lindley Site All monitoring gages were downloaded on a quarterly basis and maintained on an as needed basis The success criteria for wetland hydrology is to have a free groundwater surface within 12 inches of the ground surface for 7 5 percent of the growing season, which is measured on consecutive days under typical precipitation conditions All groundwater gages met the annual wetland hydrology success criteria for MY -1 Please refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology data and plots 13 Monitoring Year 1 Summary With the exception of SMA, all streams within the Site are stable and functioning as designed Degradation observed on SMA will be monitored for indications of long term instability A maintenance plan will be prepared after MY -2 if conditions continue to degrade The average stem density for the Site is on track to meeting the MY -5 success criteria, however, a few individual vegetation plots did not meet the MY -1 success criteria as noted in the CCPV There has been one documented bankfull event with the crest gage recorded along UT1, SF2, SF3, SF4, and SMA since construction commenced along with visual verifications such as wrack lines The MY -5 stream hydrology attainment requirement has been partially met for the Site at this time All groundwater gages met the MY -1 success criteria ON Underwood Mitigation Site Monitoring Year 1 Annual Report—FINAL Page 4 Summary information and data related to the 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 Plan documents available on NCEEP's website All raw data supporting the tables and figures in the appendices are available from NCEEP upon request 2.0 Methodology _ Geomorphic data was collected followed the standards outlined in The Stream Channel Reference Site An Illustrated Guide to Field Techniques (Harrelson et al , 1994) and in the Stream Restoration A Natural Channel Design Handbook (Doll et al , 2003) Longitudinal and cross -
