3600 Glenwood Ave, Suite 100 Raleigh, NC 27612 Corporate Headquarters 6575 West Loop South, Suite 300 Bellaire, TX 77401 res.us October 9, 2024 Casey Haywood U.S. Army Corps of Engineers Regulatory Division 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 RE: Polecat Year 7 Monitoring Report (SAW – 2016-01986) Casey, Please find attached the Polecat Year 7 Monitoring Report. All 11 permanent and three random vegetation plots met the 210 stems per acre success criteria. The stream is functioning as designed. Bankfull events were recorded on both crest gauges and the flow gauge documented 105 consecutive flow days. Based on ongoing discussions with NCDWR for the Buffer/Nutrient Section, KZ5 was planted with 10 3-gallon container trees along the top section of KZ5 to ensure the ditch top of bank was fully planted. T-posts have been installed in this area to prevent future mowing. No other areas of encroachment were noted during monitoring activities. Additionally, the recorded easement adjustment was recorded on December 12th, 2023. Comments from Monitoring Year 6 Credit Release: 1. We appreciate the immediate resolution of the encroachment on Reach KZ0. Was the encroachment addressed with the landowner or the entity responsible? The encroachment was addressed with the landowner, but he is family with the farmer. 2. The labeling and legend on the figures are not legible, please QAQC the figures prior to submission. Apologies. This has been remedied in this year’s figures. 3. A supplemental planting was conducted in May in low stem density areas along top of bank ditch KZ5, within the area of prior encroachment south of KZ0, and within wetlands along reach PC3. What was the area of the replant and at what density. To confirm, were the species planted all from the approved planting list included in the Final Mitigation Plan? The area along ditch KZ5 was approximately 800 LF. 30 bareroot trees and 110 3-gallon container trees were planted every 15 feet on both sides of the ditch. Species included swamp chestnut oak (Quercus michauxii), river birch (Betula nigra), willow oak (Quercus phellos), water oak (Quercus nigra), green ash (Fraxinus pennsylvanica), and American sycamore (Platanus occidentalis). All species were either part of the planting list from the Final Mitigation Plan or from the planted list at baseline. The encroachment area south of KZ0 was 0.1 ac planted at 250 stems per acre with 10 3-gallon container trees and 15 bareroots. Species included willow oak (Quercus phellos), river birch (Betula nigra), and swamp chestnut oak (Quercus michauxii). 2 The wetland area was 0.43 ac planted at 200 stems per acre with 50 3-gallons and 30 6ft willow poles. Species included bald cypress (Taxodium distichum), swamp chestnut oak (Quercus michauxii), overcup oak (Quercus lyrate), willow oak (Quercus phellos), and swamp white oak (Quercus bicolor). All species were either part of the planting list from the Final Mitigation Plan or from the planted list at baseline. 4. Due to the scale of the MY6 KZ-2 Flow Gauge Graph, it doesn’t appear that the gauge had 30 consecutive days of flow. If possible, it may be beneficial to adjust the scale of the graph in next year’s report. The scale has been adjusted for the Flow Gauge in this year’s report to make it easier to see when the gauge loses flow. Additionally, 39 consecutive flow days occurred at the end of 2023 as can be seen on the graph. The summary table for flow events has been updated to show this event as well as others that occurred on all gauges after the submittal of the MY6 report. 5. Please note that the powerline easement adjustment at the top of KZ5 will need to be resolved prior to the site being closed out. The easement adjustment has been completed and is discussed further in the report. The adjusted conservation easement can be seen on Figure 2 of the report. RES is requesting a 10% credit release for Year 7 monitoring (656.70 SMUs) and the close out of the Polecat Mitigation Site.

The project streams were significantly impacted by livestock access, row crop production, and nearby urbanization. The project involves the restoration and protection of streams in the Neuse River watershed. The purpose of this Site is to restore and enhance a stream complex located within the Neuse River Basin. The Site lies within USGS Hydrologic Unit Code (HUC) 03020201140010 (USGS, 2012). The 2010 Neuse River Basin Restoration Plan (RBRP) identified the Neuse River watershed (HUC 03020201140010) as a Targeted Local Watershed (TLW), a watershed that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. The Site supports many of the Neuse River RBRP and Neuse Regional Watershed Plan (RWP) goals. The Project’s watershed is primarily rural with Interstate 95 occupying the western portion of the watershed. The Project parcels have been in agricultural use for several decades. The Site is located within HUC 03020201 and includes streams that directly discharge into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. Water quality stressors that affected the Site included livestock access, row crop production, and impervious surface. The project presents 8,178 linear feet of stream restoration and enhancement generating 6,567 Stream Mitigation Units (SMU). The areas adjacent to the Site consist of agricultural fields, cattle pastures, and wooded areas. The total easement area is 53.63 acres. Invasive species were present throughout the wooded areas and will continue to be treated throughout the monitoring period. Channels restored were incised, both laterally and vertically unstable, impacted by cattle, lack riparian buffers, and aquatic life was not supported. Stream conditions along the restoration reaches exhibited habitat degradation because of impacts from livestock and nearby impervious surfaces because of urbanization. After completion of all construction and planting activities the Site will be monitored on a regular basis and a physical inspection of the Site will be conducted at a minimum of twice per year throughout the seven- year post-construction monitoring period, or until performance standards are met. These site inspections will identify site components and features that require routine maintenance. The measure of stream restoration success will be documented by bankfull flows and no change in stream channel classification. Sand bed channels are dynamic and minor adjustments to dimension and profile are expected. The measure of vegetative success for the Site is the survival of at least 210 seven-year-old planted trees per acre with an average height of 10 feet at the end of year seven of the monitoring period. Upon approval for closeout by the Interagency Review Team (IRT), the Site will be transferred to the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will be responsible for periodic inspection of the Site to ensure that restrictions required in the Conservation Easement, or the deed restriction document(s) are upheld. Endowment funds required to uphold easement and deed restrictions will be negotiated prior to site transfer to the responsible party. Polecat 3 Year 7 Monitoring Report Stream Mitigation Site October 2024 1.2 Project Goals and Objectives The 2010 Neuse River RBRP identified several restoration needs for the entire Neuse River Basin, as well as for HUC 03020201. The Polecat Creek watershed (HUC 03020201140010) was identified as a TLW, a watershed that exhibits both the need and opportunity for wetland, stream, and riparian buffer restoration. The Polecat Creek watershed includes 42 square miles of watershed area. Twenty percent of the watershed is used for agricultural purposes and three percent is currently developed. The Site was identified as a stream and buffer restoration opportunity to improve water quality, habitat, and hydrology within the Neuse River Basin. The Site is located within HUC 03020201 and includes streams that directly discharge into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. The project goals address stressors identified in the TLW and include the following: • Nutrient removal, • Sediment removal, • Invasive species treatment, • Filtration of runoff, and • Improved aquatic and terrestrial habitat. The project goals will be addressed through the following project objectives: • Exclusion of livestock, • Treatment of exotic invasive species, • Restoration of forested riparian stream buffers, • Stabilization of eroding stream banks due to lack of vegetation and livestock hoof shear, • Addition of large woody debris, such as log vanes, log weirs, and root wads, • Preservation and enhancement of hydrology in existing riparian wetlands, and • Restoration of appropriate pattern, dimension, and profile in stream channels. 1.3 Project Success Criteria The Site follows the USACE 2003 Stream Mitigation Guidelines and the “Wilmington District Stream and Wetland Compensatory Mitigation Update” dated October 24, 2016. Cross section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Stream Success Criteria Four bankfull flow events must be documented within the seven-year monitoring period. The bankfull events must occur in separate years. Otherwise, the stream monitoring will continue until four bankfull events have been documented in separate years. Intermittent stream restoration reaches will be monitored to document a minimum of 30 consecutive days of flow. This will be accomplished through direct observation and the use of stream flow gauges with data loggers. There should be little change in as-built cross-sections. If changes do take place, they should be evaluated to determine if they represent a movement toward a less stable condition (for example downcutting or Polecat 4 Year 7 Monitoring Report Stream Mitigation Site October 2024 erosion) or are minor changes that represent an increase in stability (for example settling, vegetative changes, deposition along the banks, or decrease in width/depth ratio). Cross-sections shall be classified using the Rosgen stream classification method, and all monitored cross-sections should fall within the quantitative parameters defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the entrenchment ratio shall be no less than 1.4 within restored reaches. Channel stability should be demonstrated through a minimum of four bankfull events documented in the seven-year monitoring period. Digital images will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures. Longitudinal images should not indicate the absence of developing bars within the channel or an excessive increase in channel depth. Lateral images should not indicate excessive erosion or continuing degradation of the banks over time. A series of images over time should indicate successional maturation of riparian vegetation. Vegetation Success Criteria Specific and measurable success criteria for plant density within the riparian buffers on the Site will follow IRT Guidance. Vegetation monitoring plots will be a minimum of 0.02 acres in size and cover a minimum of two percent of the planted area. Vegetation monitoring will occur between July 1st and leaf drop and includes 11 permanent vegetation plots and three random vegetation plots. The interim measures of vegetative success for the site will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year old trees at the end of Year 5, and the final vegetative success criteria will be 210 trees per acre with an average height of 10 feet at the end of Year 7. Volunteer trees will be counted, identified to species, and included in the yearly monitoring reports, but will not be counted towards the success criteria of total planted stems. 1.4 Project Components The project area is comprised of a single easement location along multiple drainage features that flow into the Neuse River. The northern easement area captures two tributaries to Polecat Branch and a portion of its headwaters. The southeastern easement area is separated from the northern area by a 100-foot crossing and is divided into three different areas due to a gas line easement and a telephone line easement. The stream mitigation components are summarized in Table 1, as well as Figure 2.

The analog method involves the use of a “template” stream adjacent to, nearby, or previously in the same location as the design reach. The template parameters of the analog reach are replicated to create the features of the design reach. The analog approach is useful when watershed and boundary conditions are similar between the design and analog reaches (Skidmore et al., 2001). Hydraulic geometry was developed using analytical methods to identify the design discharge. The Site includes Restoration, Enhancement Level I, Enhancement Level II and Enhancement Level III. Restoration was done along reaches MI1, KZ2, KZ3, KZ4, KZ5, and KZ6. Restoration reaches typically include a meandering single-thread stream pattern constructed to mimic the natural planform of a low- gradient, sand/gravel bed channel. Sinuosity depends on local reference reach conditions and hydrologic and hydraulic modeling. As a result of the restoration of planform and dimension, periodic flooding and Polecat 6 Year 7 Monitoring Report Stream Mitigation Site October 2024 restored riparian buffer provide the appropriate hydrology and sediment transport throughout this watershed. Enhancement Level I was done on Reach KZ4; Enhancement Level II and III was done along Reaches KZ0, KZ1, PC1, PC2, and PC3. Enhancement Level I included adjustments to the cross-sectional area of the existing channel and floodplains, as well as installations of wood and rock structures to adjust and enhance bedform. Enhancement Level II treatments include livestock exclusion and bank stabilization. Enhancement Level III allows high quality aquatic habitat to be protected and enhanced through invasive species treatments and supplemental plantings in the riparian buffer. 1.6 Construction and As-Built Conditions Stream construction and planting was completed in May 2018. The Polecat Mitigation Site was built to design plans and guidelines. No major changes or modifications were made during construction activities. The fence and crossings were completed in June 2018. Baseline channel length and stationing is based on design centerline. 1.7 Year 7 Monitoring Performance The Polecat Year 7 Monitoring (MY7) activities were completed in May and September 2024. All relevant monitoring data is presented below and in the appendices. The Site has met vegetation and stream success criteria required for the project to close out. Vegetation Monitoring of the 11 permanent vegetation plots and three random vegetation plots was completed during September 2024. Vegetation data are in Appendix C, associated photos and plot locations are in Appendix B. MY7 data indicates that all plots are exceeding the success criteria of 210 planted stems per acre. Planted stem densities ranged from 486 to 1,052 planted stems per acre with a mean of 778 planted stems per acre across all plots. A total of seventeen species were documented within the plots. Volunteer species were observed in ten of the fixed plots and one of the random plots. The average tree height observed was 15.9 feet, well over the final success criteria of 10 feet. The three supplemental plantings done in 2023 and mentioned in the MY6 report had high survival and vigor. In January 2024 10 3-gallon trees were planted at the top of KZ5 where encroachment has occurred in years past. This was required for Buffer Close-out. The area has also been blocked off with t-posts to prevent future mowing from occurring and assure that the new easement boundary is clear to the landowner. Species planted include Quercus michauxii (swamp chestnut oak), Quercus phellos (willow oak), and Betula nigra (river birch). No new areas of encroachment were noted. Boundary As discussed in the MY6 monitoring report, a small portion of the easement at the top of KZ5 has been changed because of the powerline above. This resulted in a reduction of the conservation easement by 0.162 acres, and a loss of approximately 0.28 acres of nutrient offset. The Riparian Buffer and Nutrient Offset Project was officially closed out on April 11, 2024. The updated conservation easement was completed on December 12th, 2023, and can be seen on Figure 2. The easement adjustment documents have been uploaded to RIBITs. Additionally, in August 2024 a survey crew checked all corners and made sure signage was updated and clearly marked. Polecat 7 Year 7 Monitoring Report Stream Mitigation Site October 2024 Stream Geomorphology Geomorphology data for MY7 was collected during May 2024. Summary tables and cross section/profile plots are in Appendix D. Overall the MY7 cross sections relatively match the as-built conditions. Bank height ratios remain less than 1.2 and entrenchment ratios greater than 1.4. Cross section 8 was noted as having some downcutting in MY5. This cross section was inspected during this monitoring year and remains relatively stable from MY5 conditions – no further downcutting was noted. Some aggredation is shown at Cross Section 7, but no instability was present during monitoring. It is RES opinion that some of this is from vegetation growth on the banks, and otherwise is accumulated sediment due to low water levels in past years. Recent heavy rains since monitoring have cleared out some of the accumulated sediment. Cross section 18 shows a minor survey inaccuracy that places the banks higher than they actually are, as evidenced by the higher start to the cross section. Remaining bank changes shown are from the increase in vegetation along the bank. No instability was observed in this cross section during monitoring. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. The channel is transporting sediment as designed. During MY7 data collection, a fallen tree and an impenetrable patch of blackberries yielded the corresponding pins inaccessible, preventing the full capture of the floodplain for cross sections 5 and 14, respectively. However, the as-built pins were used as a reference to adjust the data accordingly, and no significant differences caused by these events were noted when comparing the conditions of previous years. Stream Hydrology Crest gauges are located on reaches KZ6 and MI1, and a flow gauge is located on KZ2. There were 34 total bankfull events recorded on site in MY7; 19 on KZ6, and 15 on MI1. Flow Gauge 1 on KZ2 recorded 105 consecutive flow days and 239 cumulative flow days in MY7. Gauge locations can be found on Figure 2 and data are in Appendix E. 2.0 Methods Stream monitoring was conducted using a Topcon GTS-312 Total Station. Three-dimensional coordinates associated with cross-section data was collected in the field (NAD83 State Plane feet FIPS 3200). Morphological data was collected at 22 cross-sections. Survey data was imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. In May 2018 three sets of crest gauges and flow gauges were installed along the main project channel. The flow gauges were installed within the channel and will record flow conditions at an hourly interval. The crest gauges were installed on the bank at the bankfull elevation. During quarterly visits to the Site, the height of the corkline will be recorded. HOBO data from the flow gauges will be corrected using bankfull recordings from the crest gauges. If there are no corkline readings on the crest gauges, the height of the top of bank and water depth can be used to produce bankfull readings from the HOBO data. The flow gauge on KZ2 is corrected by using the crest of the downstream riffle to detect flow events. Vegetation success is being monitored at 11 permanent monitoring plots and three random monitoring plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data is processed using the CVS data entry tool. In the field, the four corners of each plot were permanently marked with PVC at the origin and metal conduit at the other corners. Photos of each plot are to be taken from the origin each monitoring year. The random plots are collected in the planted Non-Standard Buffer Width areas as 100 square meter belt transects. To measure the belt transects, a meter tape is stretched diagonally Polecat 8 Year 7 Monitoring Report Stream Mitigation Site October 2024 across the rows of trees and any tree that falls within width of the transect is recorded. The transects will be mapped and new locations will be monitored in subsequent years.

Each entry in the above table should have clear distinction and appropriate symbology in the asset map. 1 -Wetland Groups represent pooled wetland polygons in the map with the same wetland type and restoration level. If some of the wetland polygons within a group are in meaningfully different landscape positions, soil types or have different community targets (as examples), then further segmentation in the table may be warranted. Buffer groups represent pooled buffer polygons with common restoration levels. 2 -Wetland Position and Hydro Type - Indicates Riparian Riverine, (RR) , riparinan non-riverine (RNR) or Non-Riverine (NR) 3-Restored Footage, Acreage or Square Feet (SF) 4 -Creditible Footage, Acreage or Square feet - creditible anounts after exclusion and reductions are accounted for, such as utility impacts, crossings, single sided easements etc. General Note - The above component table is intended to be a close complement to the asset map. Each entry in the above table should have clear distinction and appropriate symbology in the asset map. 1 -Wetland Groups represent pooled wetland polygons in the map with the same wetland type and restoration level. If some of the wetland polygons within a group are in meaningfully different landscape positions, soil types or have different community targets (as examples), then further segmentation in the table may be warranted. Wetland features impacted by credit modifiers such as utilities shall be listed as a distinct record with the impacted acreage tallied as discreet records in the table (See Wetland 7 above) 2 -Wetland Position and Hydro Type - Indicates Riparian Riverine, (RR) , riparinan non-riverine (RNR) or Non-Riverine (NR) 3-Buffer Assets - due to the complex nature of buffer and nutrient offset assets they are not included in this example table. Please see the DMS buffer mitigation plan template for the required asset table information. 4 - Adjusted Mitigation Credits are based on the non-standard buffer widths.
