Gimbert kgimbert@wildlandseng.com Phone: 704.332.7754 Fax: 704.332.3306 EXECUTIVE SUMMARY Wildlands Engineering (Wildlands) implemented a full delivery project for the North Carolina Department of Environmental Quality North Carolina Division of Mitigation Services (DMS) to restore and enhance 6,795 linear feet (LF) of perennial and intermittent stream channel and to restore and create 9.5 acres (ac) of riparian wetlands on a full delivery site in Catawba County, NC. The project originally proposed the generation of 5,965 stream mitigation units (SMU's) and 7.6 wetland mitigation units (WMU's). The project stream reaches consist of UT1, UT1A, UT113 (stream restoration) and UT1C and UT1D (stream enhancement level II). The project wetland areas consist of RW1 and RW2 (wetland restoration and creation). The Lyle Creek Mitigation Site, hereafter referred to as the site, is located west of NC Highway 10 / North Main Street in the Town of Catawba, NC, on an active tree farm surrounded by woods and residential land use (Figure 1). The site is located in the Catawba River Basin Hydrologic Unit Code (HUC) 03050101140010, and North Carolina Division of Water Resources (NCDWR) Subbasin 03-08-32, which is within a DMS Targeted Local Watershed. This HUC qualifies as a service area for an adjacent HUC; as a result, the site was submitted for mitigation credit in the Catawba River Basin HUC 03050103. The site is located on one parcel owned by the Garmon Family. Prior to construction activities, the project streams were regularly modified and maintained and therefore lacked bedform diversity, habitat, and riparian buffer. The lack of bedform diversity combined with continued anthropogenic disturbance resulted in degraded aquatic habitat, altered hydrology, and water quality concerns such as lowered dissolved oxygen levels. The primary goals of the project were to provide ecological and water quality enhancements to the Catawba River Basin while creating a functional riparian corridor at the site level, providing wetland habitat and ecological function, and restoring a Piedmont Bottomland Forest as described by Schafale and Weakley (1990). These goals were achieved by restoring 5,411 LF of perennial and intermittent stream channel and 6.6 ac of wetland area, enhancing 1,384 LF of intermittent stream channel and creating 2.9 ac of wetland area. Approximately 179 LF of stream associated with the site crossings (farm roads and power line easements) was excluded from the total project credit calculations. Figure 2 and Table 1 present the restoration design for the site. The following project goals were established in the mitigation plan to address the effects listed above from project site stressors: Wetland areas will be disked to increase surface roughness and better capture rainfall which will improve connection with the water table for groundwater recharge. Adjacent streams will be stabilized and established with a floodplain connection to promote hydrologic transfer between wetland and stream; • A channel with riffle -pool sequences and some rock and wood structures will be created in the steeper project reaches and a channel with run -pool sequences and woody debris structures will be created in the low sloped project reaches for macroinvertebrate and fish habitat. Introduction of wood including root wads and woody 'riffles' along with native stream bank vegetation will substantially increase habitat value. Gravel areas will be added as appropriate to further diversify available habitats; • Adjacent buffer areas will be restored by removing invasive vegetation and planting native vegetation. These areas will be allowed to receive more regular and inundating flows. Riparian wetland areas will be restored and enhanced to provide wetland habitat; and • Sediment input from eroding stream banks will be reduced by installing bioengineering and in - stream structures while creating a stable channel form using geomorphic design principles. Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL Construction and planting activities were completed by River Works in April 2012. A Conservation Easement held by the State of North Carolina has been recorded with the Catawba County Register of Deeds on the 26.62 -acre project area within the Garmon parcel. The conservation easement protects the project area in perpetuity. Monitoring Year 5 (MY5) monitoring and site visits were completed between February and November 2016 to assess the conditions of the project. A majority of groundwater gages (GWG) at the site have met the required hydrologic success criteria for MY5, exceptions include GWG 6 and 9. These two gages are the only ones that have not met hydrologic success criteria during a majority (at least 3 out of 5 years) of post -construction monitoring. All project streams have met the required success criteria of exhibiting two overbank events in separate monitoring years. All streams within the site are stable and meeting the MY5 success criteria with the exception of the upper reach (approximately 394 LF) of UT1A. UT1A has aggraded due to a large influx of sediment from upstream of the project. The site's overall average stem density of 419 stems/acre is greater than the final vegetative success criteria of 260 stems/acre for MY5. Based on the performance of project components through MY5, credit is not proposed for 394 LF of stream restoration (394 SMU's) along UT1A that has aggraded due to offsite sediment sources. Credit is not proposed for 0.6 acres of wetland creation (0.2 WMU's) in RW1 where groundwater gages (GWG 6 and 9) within the right floodplain of UT1 Reach 1 have not met hydrologic success criteria during the majority of monitoring years. Based on these modifications to proposed credits the project is anticipated to generate 5,571 SMU's and 7.1 WMU's.

The site is located in the Catawba River Basin HUC 03050101140010, and NCDWR Subbasin 03-08-32, which is within a DMS Targeted Local Watershed. This HUC qualifies as a service area for an adjacent HUC; as a result, the Lyle Creek Mitigation Site was submitted for mitigation credit in the Catawba River Basin HUC 03050103. The site is located west of NC Highway 10/ North Main Street in the Town of Catawba, NC, on an active tree farm surrounded by woods and residential land use. The Site is bounded by Lyle Creek to the north, NC Highway 10/ North Main Street to the east and an elevated railroad right-of-way to the south. The project stream reaches consist of UT1, UT1A, UT113 (stream restoration) and UT1C and UT1D (stream enhancement level II). The project wetland areas consist of RW1 and RW2 (wetland restoration and creation). Mitigation work within the site included restoring and enhancing 6,795 LF of perennial and intermittent stream channel and restoring and creating 9.5 ac of riparian wetland and proposes the generation of 5,571 SMU's and 7.1 WMU's. The stream and wetland areas were planted with native vegetation to improve habitat and protect water quality. Construction and planting activities were completed by River Works in April 2012. The site is located on one parcel owned by the Garmon Family. A Conservation Easement held by the State of North Carolina has been recorded with the Catawba County Register of Deeds on the 26.62 -acre Lyle Creek project area within the Garmon parcel. The conservation easement protects the project area in perpetuity. Directions and a map of the site are provided in Figure 1 and project components are illustrated for the site in Figure 2. 1.1 Project Goals and Objectives Prior to construction activities, the project streams were regularly modified and maintained and therefore lacked bedform diversity, habitat, and riparian buffer. The primary impacts to the project streams were the result of mowing, ditching, vegetation maintenance, and dredging associated with tree farming activities. As a result of the aforementioned land activities, the onsite streams were incised and overly wide with shallow flow. The streams were unable to maintain their channel form and subsequently filled in with sediment, organic matter, and vegetation. In -stream bedform diversity was extremely poor and the longitudinal profile was dominated by shallow runs. The lack of bedform diversity combined with continued anthropogenic disturbance resulted in degraded aquatic habitat, altered hydrology (related to loss of floodplain connection and lowered water table), and water quality concerns such as lower dissolved oxygen levels (due to shallow flow with few re -aeration points). Table 4 in Appendix 1 and Tables 10a, 10b, and 10c in Appendix 4 present the pre -restoration conditions in detail. The primary goals of the project were to provide ecological and water quality enhancements to the Catawba River Basin while creating a functional riparian corridor at the site level, providing wetland habitat and ecological function, and restoring a Piedmont Bottomland Forest as described by Schafale and Weakley (1990). These goals were achieved by restoring 5,411 LF of perennial and intermittent stream channel and 6.4 ac of wetland area, enhancing 1,384 LF of intermittent stream channel and creating 2.2 ac of wetland area. Approximately 179 LF of stream crossings (farm roads and power line easements) were excluded from the total project credit calculations. The site's riparian areas were also planted to stabilize streambanks and wetland areas, improve habitat, and protect water quality. The ecological uplift can be summarized as starting from tree farming -impacted streams and wetlands and moving to stable channels and wetlands in a protected riparian corridor. Restoration of dimension, Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-1 pattern, and profile was implemented for UT1, UT1A, and UT1B; enhancement of profile and dimension was implemented for UT1C and UT11D. Wetland restoration and creation included RW1 and RW2. UT1A and UT113 discharge into an anastomosed wetland complex upstream of their confluence with UT1 as depicted in Figure 2. This anastomosed wetland complex was not proposed for stream mitigation credit. Figure 2 and Table 1 present the implemented design for the site. Monitored enhancements to water quality and ecological processes established in the mitigation plan (approved 8/2011) are outlined below, followed by expected project benefits which are associated with restoration, but will not be monitored as part of this project: Monitored Project Goals Wetland areas will be disked to increase surface roughness and better capture rainfall which will improve connection with the water table for groundwater recharge. Adjacent streams will be stabilized and established with a floodplain elevation to promote hydrologic transfer between wetland and stream; • A channel with riffle -pool sequences and some rock and wood structures will be created in the steeper project reaches and a channel with run -pool sequences and woody debris structures will be created in the low sloped project reaches for macroinvertebrate and fish habitat. Introduction of wood including root wads and woody 'riffles' along with native stream bank vegetation will substantially increase habitat value. Gravel areas will be added as appropriate to further diversify available habitats; • Adjacent buffer areas will be restored by removing invasive vegetation and planting native vegetation. These areas will be allowed to receive more regular and inundating flows. Riparian wetland areas will be restored and enhanced to provide wetland habitat; and • Sediment input from eroding stream banks will be reduced by installing bioengineering and in - stream structures while creating a stable channel form using geomorphic design principles. Expected Project Benefits • Chemical fertilizer and pesticide levels will be decreased by filtering runoff from adjacent tree farm operations through restored native buffer zones and wetlands. Offsite nutrient input will be absorbed onsite by filtering flood flows through restored floodplain areas and wetlands, where flood flows can disperse through native vegetation and be captured in vernal pools. Increased surface water residency time will provide contact treatment time and groundwater recharge potential; • Sediment from offsite sources will be captured during bankfull or greater flows by deposition on restored floodplain areas where native vegetation will slow overland flow velocities; • Restored riffle/step-pool sequences on the upper reach of UT1A, where distinct points of re- aeration can occur, will allow for oxygen levels to be maintained in the perennial reaches. Small log steps on the upstream portion of UT113 and UT1 Reach 1 Upper will also provide re -aeration points; and • Creation of deep pool zones will lower temperature, helping to maintain dissolved oxygen concentrations. Pools will form below drops on the steeper project reaches and around areas of woody debris on the low -sloped project reaches. Establishment and maintenance of riparian buffers will create long-term shading of the channel flow to minimize thermal heating. 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. Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-2 The stream restoration success criteria for the site follows the approved performance criteria presented in the DMS Mitigation Plan Template (Version 1.0, 11/20/2009) and the Stream Mitigation Guidelines issued in April 2003 by the U.S. Army Corps of Engineers (USACE) and DWR. Annual monitoring and quarterly site visits will be conducted to assess the condition of the finished project for five years, or until success criteria are met. The stream restoration reaches (UT1, UT1A, and UT113) of the project were assigned specific performance criteria components for stream morphology, hydrology, and vegetation. The enhancement reaches (UT1C and UT1D) were documented through photographs and visual assessments to verify that no significant degradational changes are occurring in the stream channel or riparian corridor. Monitoring for wetland vegetation will extend five years beyond completion of construction. The wetland restoration and creation sections have been assigned specific performance criteria for hydrology and vegetation. The final mitigation plan was submitted and accepted by the DMS in August 2011. Construction activities were completed by River Works, Inc. in April 2012. Baseline monitoring (MYO) and as -built survey was conducted between April and May 2012. Annual monitoring has been conducted for five years including stream, vegetation, and wetland assessment. The final monitoring activities were conducted in 2016 with the close-out anticipated to commence in 2017 given the success criteria are met. Appendix 1 provides more detailed project activity, history, contact information, and watershed/site background information for this project. 1.2 Monitoring Year 5 Data Assessment Annual monitoring and quarterly site visits were conducted between February and November 2016 to assess the condition of the project. 1.2.1 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., 2008). A total of 35 vegetation monitoring plots were established during the baseline monitoring within the project easement areas using a standard 10 by 10 -meter plot. The final vegetative success criteria will be the survival of 260 planted stems per acre at the end of year five of the monitoring period. The site was re -planted in late winter 2012 in response to the dead bare roots observed during the MY1 vegetative survey. Most likely, the mortality of planted stems during MY1 was a result of dry soil conditions, low precipitation, and/or from grass suffocation or crowding of planted stems. Replanting was conducted across the site with focus in and around areas not meeting success criteria after MY1 (such as plots 4, 5, 7, 10, 12, 19, 21, 29, & 30) and included approximately 1,200 additional stems. The MY2 vegetation survey resulted in an 11% increase in stem density due to supplemental planting and the re -sprout of existing bare roots. After the MY2 vegetation survey an additional supplemental planting was conducted within the vicinity of plots 4, 6, and 19. During the spring of 2014, approximately 200 1 -gallon containerized trees were planted in and around these plots. During MY4 additional stems were observed in several plots whose composition, stem height, and location correlate to the supplemental plantings in 2012 and 2014. These additional stems were assumed to be planted stems missed in previous monitoring years. The MY5 annual vegetation monitoring was completed in June 2016 and resulted in an average planted stem density of 419 stems per acre for the site, which is greater than the final success criteria requirement. All 35 vegetation plots individually meet the year 5 final criteria of 260 stems/acre. Planted stem densities ranged from 283 — 607 stems per acre. A strong presence of volunteers was observed in several plots. When volunteers are included the total stem densities ranged from 283 —1,619 stems per acre with an overall average of 667 stems per acre. Between four and ten native woody species were documented in the vegetation plots with 26 species present site wide. Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-3 1.2.2 Vegetative Areas of Concern The MY5 vegetation monitoring and visual assessment revealed few vegetation areas of concern. Invasive species including Chinese privet (Ligustrum sinense), Chinese lespedeza (Lespedeza cuneate), Johnsongrass (Sorghum halepense), kudzu (Pueraria lobata), and multiflora rose (Rosa multiflora) were identified at a few isolated areas during MY5. The presence of these species does not currently appear to be affecting the survivability of planted stems. Minor encroachment of the conservation easement was observed as a result of adjacent field mowing performed by the surrounding tree farm. Refer to Appendix 3 for vegetation summary tables and raw data tables and to Appendix 2 for vegetation plot photographs, the vegetation condition assessment table and Figures 3.0-3.3 for the Integrated Current Condition Plan View which outlines these areas of concern. Maintenance Plan Currently the invasive species identified on the site do not appear to be negatively affecting planted stems but will be treated during Spring 2017. Additional conservation easement markers will be installed along areas of encroachment. 1.2.3 Stream Assessment Morphological surveys for MY5 were conducted between May and September 2016. The majority of the streams within the site have met the success criteria for MY5. Aggradation was documented on the upper portions of UT1, UT1A, and UT16 as a result of their contributing upstream watersheds. The aggradation at the top of UT1 (Stations 100+17 and 100+95) is contained within the active channel and resulted in a slight rise in channel bed elevation through this section. The minor amount of sediment was first observed in MY4 and currently is not impacting the channel's overall stability and function. Aggradation in UT1A was initially documented during MY3 between Stations 301+75 to 304+34 and continued through MY4 when sediment filled the channel between Stations 300+36 to 304+34. During MY5 sediment filled UT1A from Station 300+36 to 304+30. This portion of UT1A has served as a reservoir for off-site sediment which has completely filled in this portion of channel. UT1B experienced minor aggradation between Stations 201+52 and 204+30 to a lesser degree than UT1A. This aggradation in not impacting the overall stability of UT113 as the channel has remained a single thread system with some decrease in pool length and depth. Over time UT1 and UT16 should naturally transport this sediment. Refer to Appendix 2 for the visual assessment table, Integrated Current Condition Plan View (CCPV), photographs, and Appendix 4 for morphological data and plots. Surveyed riffle cross-sections fell within the parameters defined for channels of the appropriate Rosgen stream type with the exception of cross-sections 9 and 13 along UT1A due to aggradation from the contributing upstream watershed. Two additional cross-sections were installed in MY4 at Stations 308+41 and 310+26 of UT1A to characterize this downstream portion of the reach (refer to Figure 2 and 3). All cross-sections were monitored within the guidelines presented in the mitigation plan. In general cross-sections along UT1 and UT113 show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio. The surveyed longitudinal profile data for the stream restoration reaches illustrate that the bedform features are maintaining lateral and vertical stability throughout UT1, and the lower sections of UT1A and UT1B. In UT1, the downstream section of UT1A, and the majority of UT1B, the riffles and runs 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 1.0. In the aggraded section of UT1A, the sediment load remains extended above the top of bank. Pools within the aggraded section of UT1B are less distinguishable and resemble shallow runs (Appendix 4, Longitudinal Profile Plots). Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-4 Due to the sand/silt nature of the substrate throughout the project, fluctuations in bed elevations were observed and expected as described in the mitigation plan. These fluctuations within UT1 are temporary and seem to typically correspond to storm events. In -stream structures, such as brush mattresses and sod mats used to enhance channel habitat and stability on the outside bank of meander bends continue to provide stability and habitat as designed. No changes were observed during MY5 that indicate a change in the radius of curvature or channel belt width. Therefore, no pattern data were collected during MY5. 1.2.4 Hydrology Assessment As of MY5, two or more bankfull events have occurred in separate years within all the restoration reaches (UTI, UT1A and UT1B). During MY5, one bankfull events was recorded on UT1 using a crest gage. Due to high sedimentation rates on UT1A, the crest gage located at cross section 9 was relocated to station 305+16 on UTIA downstream of the aggraded section of the stream. Refer to Table 13 in Appendix 5 for hydrologic data. 1.2.5 Wetland Assessment Eight groundwater monitoring gages (GWG 1— 8) were established during the baseline monitoring throughout the wetland restoration and creation areas. The gages were installed at appropriate locations so that the data collected will provide an indication of groundwater levels throughout the wetland project area. Three additional gages (GWG 9 —11) were also installed during subsequent monitoring years. GWG 10 was added within the wetland restoration portion of RW1. GWG 9 and 11 were added to creation areas in RW2. A barotroll logger and a rain gage were also installed onsite. Historical growing season data is not available for Catawba County therefore the growing season used for success criteria in previous monitoring years was applied from nearby Iredell County whose growing season runs from April 8th to October 27th (202 days). Additional growing season data are being collected by two soil temperature loggers that were installed, one within each wetland. Based on discussions with the United States Army Corps of Engineers (USACE) the on-site soil temperature data may be used to determine the beginning of the growing season and Natural Resources Conservation Service (NRCS) WETS data to determine the end of the growing season. During MY5 the two on-site soil temperatures reached and/or stayed above 41 degrees Fahrenheit at 12 inches below the ground surface starting on February 21St and 22nd which are 48 and 47 days, respectively, earlier than the Iredell County growing season defined by the WETS data that starts on April 8th. Based on general experience the Interagency Review Team (IRT) typically does not accept growing season start dates before March 9th in the Piedmont. Therefore, the growing season was only extended by 30 days from March 91h to October 27th (232 days). All groundwater monitoring gages were downloaded on a quarterly basis and were maintained on an as needed basis. The success criteria for wetland hydrology at this site is to have a free groundwater surface within 12 inches of the ground surface for seven percent of the growing season, which is measured on consecutive days under typical precipitation conditions. The majority of groundwater gages (9 out of 11 gages) met the annual wetland hydrology success criteria for MY5. Exceptions include GWG 6 and 9 located on the western side of the site. Monthly on-site rainfall was below average for the majority of the growing season. Refer to Appendix 2 for the groundwater gage locations and Appendix 5 for groundwater hydrology data and plots. 1.2.6 Benthic Macroinvertebrate Assessment Prior to site construction, three macroinvertebrate assessment locations were established at the site (UTI Upper Reach, UT1 Lower Reach and UT113) as shown on Figure 3. These sites were sampled before Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-5 construction (December 2011), MY -2 (January 2014), MY3 (January 2015), and MY4 (January 2016). Sampling was conducted using an abbreviation of the standard qualitative method (Qual 4) in compliance with the North Carolina Rapid Bioassessment Standard Operating Procedures for Benthic Macroin vertebrates set by North Carolina Department of Environmental Quality (NCDEQ, 2012). Samples were assessed and identified at the species level by Pennington & Associates, Inc. Overall taxa richness decreased from pre -construction to MY4 at the three sampling locations. Ephemeroptera + Plecoptera + Trichoptera (EPT) taxa richness increased from pre -construction to MY4 on UT1 Lower while EPT taxa richness decreased on UT1 Upper and UT113. MY4 NC biotic indices at each sampling location were lower than pre -construction values indicating pollutant intolerant bugs are establishing across the site. 1.3 Monitoring Year 5 Summary Streams within the site are stable and functioning as designed. Aggradation documented in UT1A persists. Wildlands has removed this 394 LF from the credit request. Lesser amounts of aggradation where observed on the upper portion of UTI and UT113 however these channels are stable and functioning as single thread channels. It is anticipated that aggraded sediment in UT1 and UT1B will be evacuated from the system. The average stem density for the site has met the MY5 success criteria. There have been more than two bankfull events recorded in separate monitoring years along each restored project reach since construction commenced; therefore, the site has met the MY5 stream hydrology attainment requirement. A majority of groundwater gages (9 out of 11 gages) met the wetland hydrology success criteria for MY5. Wildlands has removed 0.6 acres of wetland creation located on the west side of UTI in the area represented by GWG 6 and 9 from our credit request. 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 DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Lyle Creek Mitigation Site Monitoring Year 5 Annual Report -FINAL 1-6 Section 2: METHODOLOGY Geomorphic data was collected following 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-sectional data were collected using a total station and were georeferenced. All Integrated Current Condition Plan View mapping was recorded using a Trimble handheld GPS with sub -meter accuracy and processed using was Pathfinder and ArcView. Crest gages were installed in surveyed riffle cross-sections and monitored quarterly. Hydrology attainment installation and monitoring methods are in accordance with the USACE (2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey-NCEEP Level 2 Protocol (Lee et al., 2008).

Oxford School Road becomes North Main Street (NC Highway 10) after a bridge crossing at Lyle Creek. From North Main Street, turn right onto 3rd Avenue NW. Follow 3rd Avenue NW around and to the right to approach the Catawba Tree Farm gate. The subject project site is an environmental restoration site of the Department of Environmental Quality (DEQ) Division of Mitigation Services (DMS) and is encompassed by a recorded conservation easement,but is bordered by land under private ownership. Accessing the site may require traversing areas near or along the easement boundary and therefore access by the general public is not permitted. Access by authorized personnel of state and federal agencies or their designees/contractors involved in the development, oversight,and stewardship of the restoration site is permitted within the terms and timeframes of their defined roles. Any intended site visitation or activity by any person outside of these previously sanctioned roles and activites requires prior coordination with DMS. 3. yr a R.— Owl , :r. 4yh lacer r 10305011150 20 11FININhAw Ike I Project Locationi AA yes 0305�01 150 6 lli Figure 1.
