Site visit notes from the visit are included in Appendix G. • Easement encroachment was observed during visual assessment site visits along the northwest parcel boundary of UT1-Reach 3 (all very minor and under 500 sq. ft.), WE1's southeastern easement boundary (under 0.10 acres), and the southeastern easement boundary along UT1- Reach 1 (0.331 acres). RS had k2 Design (project surveyor) re -survey the easement boundaries of UT1, Reaches 1-3, and WE1 in early November 2022. Easement marking and replanting of encroached areas with 3-gal. containerized trees were completed on November 10, 2022. A detailed report of 2022 maintenance work is provided in Section 2.2. • No evidence of nuisance animal activity (i.e., heavy deer browsing, beaver activated, etc. ) was observed. Streams • Stream monitoring measurements indicate minimal changes in the cross -sections as compared to as -built data. The channel geometry compares favorably with the proposed conditions outlined in the Detailed Restoration Plan and as constructed. • Across the Site, all in -stream structures are intact and functioning as designed. No stream areas of concern were identified during year 3 (2022) monitoring. Tables for Year 3 (2022) data and annual quantitative assessments are included in Appendix D. • All seven flow gauges recorded continuous flow for more than the 30-days. Recorded flow periods ranged from 67 to 186 consecutive days (Appendix Q. • One bankfull event was documented in year 3 (2022) monitoring. Four bankfull events have been recorded to date, with one occurring during all three monitoring years (Table 16, Appendix Q. Wetlands • Twelve of thirty-five groundwater gauges met success criteria for the year 3 (2022) monitoring period (Appendix Q. The on -site reference gauge also failed to meet success criteria in year 3 (2022). Rainfall data indicate dry conditions for much of the year: precipitation was below the 30th percentile from February to June, according to WETS data (Appendix Q. USGS drought monitoring indicates Johnston County was subject to periods of abnormally dry to moderate drought conditions dating back to September of 2021 and throughout much of 2022 (Graphic 1. USGS 2021-2022 Drought Conditions, Appendix Q. Across the Site, the development of herbaceous hydrophytic species is abundant. Vegetation • Thirty-one of the thirty-two fixed vegetation monitoring plots met success in Year 3 with an average of 502 stems/acre. Additionally, 15 of 18 random transects met success with an average of 398 stems/acre. Woody vegetation continues to thrive across the Site, with stem heights reaching 10+ feet in places. Beyond the areas of encroachment, no areas of vegetation concern were identified in year 3 (2022).

Connectivity • Improved aquatic connectivity to Hannah Creek Not Functioning Functioning 1.2 Project Background The Alliance Headwaters Mitigation Site (Site) is in Johnston County, approximately six miles southeast of Four Oaks and one mile east of US 701 (Figure 1, Appendix A). The Project is located within the NC Division of Mitigation Services (DMS) targeted watershed for the Neuse River Basin Hydrologic Unit (HU) 03020201150020 and the NC Division of Water Resources (NCDWR) subbasin 03-04-04. The Site has existed in its pre -construction condition since approximately 2005. A review of historic aerials of the Site, and adjacent parcels, taken in 1939, 1965, 1971, 1988, and 2005, revealed that while agriculture was prevalent in the area, much of the Site was not converted to agricultural uses until after 1997/1998. Additional aerial photographs from Google Earth show that before construction, the project Monitoring Report MY3 (Project No. 97086) page 1 Alliance Headwaters Mitigation Site Restoration Systems, LLC Johnston County, North Carolina February 2023 site had been manipulated for agricultural production numerous times between 1997/1998 and 2019. The channelization of perimeter ditches to carry stream flow undermined the hydrologic connection between the headwaters of UT3 and UT4 (located in the forested sections of the Site) from their downstream channels. In addition, two small impoundments were excavated on the historical flow paths of UT1 and UT3 during this time. Current land use near the Site is predominately agriculture (crop and livestock production) and silviculture. While the Site is near (< 6 miles) to two major interstates (1-95 and 1-40), there are no foreseeable signs of impending land use changes or development pressure that would impact the Project's watershed. The conservation easement will eliminate the potential for future development and/or agricultural use in the floodplain areas of the restored streams. 1.3 Project Components and Structure Proposed Site restoration activities generated 6029 Stream Mitigation Units (SMUs) and 39.4 riverine Wetland Mitigation Units (WMUs) within a 71.7-acre conservation easement as the result of the following. • Restoration of 6,529 linear feet of stream channels that have been straightened and channelized for agricultural purposes • Restoration of 32.6 acres of drained hydric soil to riparian riverine wetlands as the result of stream restoration activities and ditch plugging • Areas of potential wetland riparian riverine restoration total approximately 7.0 acres of drained soils with hydric inclusions • Enhancement of 0.38 acres of jurisdictional riparian headwater forest through stream realignment activities and supplemental wetland plantings • Creation of 1.99 acres of riparian riverine wetlands in areas of drained hydric soil requiring bench excavation • Preservation of 16.39 acres of jurisdictional riparian riverine wetlands located within forested headwater systems Additional activities that occurred at the Site included the following. • Planting 49.9 acres of the Site with 35,200 stems (planted species and densities by zone are included in Table 7 [Appendix Q • Application of permanent seed mix across 49.9 acres of the Site and temporary seed mix consisting of grain rye, millet, clover, and turnip The Site's design was completed in October 2018. Construction started on May 13, 2019, and ended with a final walkthrough on July 31, 2019. The Site was planted on January 16, 2020. Completed project activities, reporting history, completion dates, project contacts, and background information are summarized in Tables 1-4 (Appendix A). 1.4 Success Criteria Performance criteria outlined in the NCDMS Mitigation Plan Template (ver. 10/2015) and US Army Corps of Engineers — Wilmington District Public Notice: Notification of Issuance of Guidance for Compensatory Stream and Wetland Mitigation Conducted for Wilmington District (October 24, 2016), will be followed and are briefly outlined below. Monitoring data collected on the Site will include reference photos, plant survival analyses, channel stability analyses, wetland hydrological analyses, and biological data if specifically required by permit conditions. Monitoring Report MY3 (Project No. 97086) page 2 Alliance Headwaters Mitigation Site Restoration Systems, LLC Johnston County, North Carolina February 2023 Monitoring will be conducted for seven years unless the USACE, in consultation with the Interagency Review Team (IRT), agrees that monitoring may be terminated early. Early closure will only be provided through written approval from the USACE in consultation with the IRT. Annual monitoring reports will be submitted to the NCDMS by IRS no later than November 30 of each monitoring year. Table B: Success Criteria Streams • All streams must maintain an Ordinary High -Water Mark (OHWM), per RGL 05-05. • A continuous surface flow must be documented each year for at least 30 consecutive days. • Bank height ratio (BHR) cannot exceed 1.2 for a majority of measured cross sections on a given reach. • Entrenchment ratio (ER) must be 2.2 or above for a majority of measured riffle cross -sections on a given reach. • BHR and ER should not change by more than 10% in any given year for a majority of a given reach. • Must document the occurrence of at least 4 bankfull events in separate years during the monitoring period. Wetland Hydrology • Saturation or inundation within the upper 12 inches of the soil surface for, at a minimum, 10 percent of the growing season during average climatic conditions. Note: Soil temperature for growing season establishment will be determined using a continuously logging soil probe installed at the rain gauge. Soil temperature will be measured from mid -February through the end of April (at a minimum). Vegetation • Within planted portions of the Site, a minimum of 320 stems per acre must be present at year 3; a minimum of 260 stems per acre must be present at year 5; and a minimum of 210 stems per acre must be present at year 7. • Trees must average 7 feet in height at year 5 and 10 feet in height at year 7. • Planted and volunteer stems are counted, provided they are included in the approved planting list for the Site. • Any single species can only account for 50% of the required stems per monitoring plot. 2.0 METHODS Monitoring requirements and success criteria outlined in this plan follow the October 24, 2016, NC Interagency Review Team Wilmington District Stream and Wetland Compensatory Mitigation Update. Monitoring will be conducted by Axiom Environmental, Inc. Annual monitoring reports of the data collected will be submitted to the NCDMS by Restoration Systems no later than December 31 of each monitoring year data is collected.

Stream morphology data is available in Appendix D. All seven flow gauges recorded continuous flow for more than the 30-days. Several stream gauges malfunctioned during the spring and summer of year 3 (2022). These gauges were relaunched/replaced as soon as the malfunction was discovered. As of November 2, 2022, all gauges have been repaired/replaced, are functioning correctly, and are recording stream flow measurements. Recorded flow periods ranged from 67 to 186 consecutive days (Appendix Q. One bankfull event was documented in year 3 (2022) monitoring. Four bankfull events have been recorded to date, with one occurring during all three monitoring years (Table 16, Appendix Q.

Monitoring Report MY3 (Project No. 97086) page 5 Alliance Headwaters Mitigation Site Restoration Systems, LLC Johnston County, North Carolina February 2023 Twelve of thirty-five groundwater gauges met success criteria for the year 3 (2022) monitoring period (Appendix Q. The on -site reference gauge also failed to meet success criteria in year 3 (2022). Rainfall data indicate dry conditions for much of the year: precipitation was below the 30' percentile from February to June, according to WETS data (Appendix Q. USGS drought monitoring indicates Johnston County was subject to periods of abnormally dry to moderate drought conditions dating back to September of 2021 and throughout much of 2022 (Graphic 1. USGS 2021-2022 Drought Conditions, Appendix Q. Across the Site, the development of herbaceous hydrophytic species is abundant. Vegetation Summary During quantitative vegetation sampling, 32 sample plots (10-meter by 10-meter) were installed within the Site as per guidelines established in CVS-EEP Protocol for Recording Vegetation, Version 4.2 (Lee et al. 2008). Year 3 (2022) measurements also included 18 random sample plots (a mix of 50-meter by 2- meter and 25-meter by 4-meter). Measurements of all 50 plots resulted in an average of 465 stems/acre, excluding live stakes. Additionally, 31 of the 32 permanent plots and 15 of the 18 temporary transects met the success criteria. Plots 25, 28, 29, and 30 were each one stem shy of meeting success criteria based on planted stems alone, but when including naturally recruited stems of swamp chestnut oak (Quercus michauxii), a desirable species that was originally included in the Site planting plan, plots 25, 28, and 30 met success. Planted stem mortality in these plots is likely due to localized seasonal inundation of these areas. Three temporary transects in the vicinity of these plots (Transects 11, 15, 18) met success criteria, all with >400 stems/acre. Transects 2, 5, and 13 failed to meet the success criteria, which is likely due to dense herbaceous competition in the area. Permanent plots located adjacent to each of these transects met the success criteria. The year 3 (2022) vegetation data summaries are provided in Tables 8-11 of Appendix C. 2.2 2022 Maintenance & 2023 Monitoring Gauge Updates All 2022 maintenance work is graphically depicted in Figure 3, Appendix B. Surface Water Alterations (eastern easement boundary of UT3-Reach 1 and 2) During the summer of 2022, IRS added a surface water outlet along the agricultural road running adjacent to the southeastern easement boundary of UT3's Reaches 1 and 2. One outlet was added near GW-19, but cutting the ag. road down to match the adjacent ag. field and easement elevation. A temporary seed mix was applied, and containerized trees planted (Appendix F. Site Photos). Agricultural Encroachment / Additional Signage: Easement encroachment was observed during visual assessment site visits along the northwest parcel boundary of UT1-Reach 3 (all very minor and under 500 sq. ft.), WE1's southeastern easement boundary (under 0.10 acres), and the southeastern easement boundary along UT1-Reach 1 (0.331 acres). IRS had k2 Design (project surveyor) re -survey the easement boundaries of UT1, Reaches 1-3, and WE1 in early November 2022. Following the survey effort, IRS replaced several of the easement corner markers with 6-inch treated fence posts and new conservation easement signage. In addition, IRS added 6-inch treated fence posts and new conservation easement signage to areas where long straight stretches of easement would benefit from additional marking; specifically areas of previous encroachment and the agricultural road along the southern easement boundary of UT1 Reach 3 and UT2 - (Appendix F. Site Photos). Monitoring Report MY3 (Project No. 97086) page 6 Alliance Headwaters Mitigation Site Restoration Systems, LLC Johnston County, North Carolina February 2023 Upon the completion of additional easement marking, 50, 3-gallon potted trees were planted within areas of encroachment —Table F. The location of planting is shown in Figure 3, Appendix B. Easement marking, and 3-gal. planting occurred on November 10, 2022 (Appendix F. Site Photos).

Below is a list of attendees and general site visit notes. Attendees: USAC E: - Todd Tugwell - Casey Haywood NC DWR: - Erin Davis Restoration Systems: - Raymond Holz - Alex Baldwin Division of Mitigation Services: - Lindsay Crocker Site Visit Notes: - IRS will include a random vegetation transect through the UT 2 Wetland Enhancement Area during MY4 (2023). - IRS will ensure proper easement signage/marking along all Site's agriculture boundaries. This effort will include the southern easement boundary of the eastern tract along the gravel ag. road. This effort will consist of treated 6-inch fence posts at all easement corners and adequate marking every 200 feet with easement signage. - IRS will implement an initial treatment to pines throughout the easement in Q1 2023 — paying particular attention to pines on and along stream banks. IRS will also plant live stakes in areas where pines are removed from the stream banks. - Between groundwater gauges 24 and 30, IRS will install a shorter/shallower groundwater gauge to see if the deeper gauges (24 and 30) have punctured through the restrictive soil layer. - If 2022 photos are available that show the streams/site in a wetter condition, IRS will provide them in the MY 3 (2022) monitoring Report. - In the MY 3 (2022) monitoring report, IRS will provide pictures of the improved road outlets. This includes the additional outlet constructed near groundwater gauge 19 — installed in August of 2022. The purpose of these outlets is to allow surface hydrology to enter the Site from adjacent agricultural fields. - IRS will perform groundwater gauge maintenance across the Site, ensuring bentonite caps are in place and level with the surrounding ground elevation. - IRS will review alternative approaches to monitoring stream flow and switch stream -flow gauges if appropriate. 1101 Haynes St., Suite 211 • Raleigh, NC 27604 • www.restorationsystems.com • Ph 919.755.9490 • Fx 919.755.9492 Ray Holz From: Haywood, Casey M CIV USARMY CEMVP (USA)<Casey.M.Haywood@usace.army.mil> Sent: Monday, October 31, 2022 1:03 PM To: Tugwell, Todd J CIV USARMY CESAW (USA); Davis, Erin B; Ray Holz Cc: Crocker, Lindsay; Alex Baldwin Subject: RE: [Non-DoD Source] RE: [External] Alliance Headwaters / MY2 (2021) and MY 3 (2022) IRT Site Visit /.
