The following is a point -by -point response addressing those comments. Additionally, an updated copy of the MY6 Report will be submitted. 1. CCPVs should be georeferenced PDFs in the report. Additionally, the resolution is low on the CCPVs and some labels and features are difficult to read. Please submit higher resolution, georeferenced CCPVs exported from ArcMap (or ArcGIS Pro) in the report. Ecotone Response: All CCPVs have been updated with higher resolution images (pages 11-16). 2. DMS personnel walked the site on January 6 and observed dense pine in the upper portion of Reach 1. Is there any plan to thin pine in this area in MY7? Ecotone Response: This isolated stand of pine is a small percentage of the overall tree coverage in the project site. Considering the hardwood stem survival count, there is not an immediate need to thin the pine stand referenced here, but continued monitoring of tree survival will inform possible need for action in the future. 3. Please submit a feature characterizing the 20 ft. of erosion located along Reach 3. Ecotone Response: Erosion is now marked on CCPV of Reach 3 on page 14 of the report. 4. The figure for monitoring well 2 has numeric values on the x-axis instead of dates. Ecotone Response: Figure 4 on page 56 has been corrected to show dates on the x-axis. Thank you for your consideration of these monitoring report comments. We appreciate your assistance with our project thus far, and we look forward to working with you to complete the review process.

It is located in Beaufort County, NC and the Tar -Pamlico River Basin (USGS 03020104). Mitigation components include five stream reaches totalling 2,891 linear feet contained within a Conservation Easement. Construction was completed in 2015 and planting completed in 2016. The first of seven monitoring years was initiated in 2016. Year 6 monitoring was completed on October 25, 2020. 2.0 PROJECT GOALS AND OBJECTIVES The project goals of the Hudson Property stream restoration project per the approved mitigation plan are as follows: • Improve and sustain hydrologic connectivity/interaction and storm flow/flood attenuation. • Reduce nutrient and sediment stressors to the reach and receiving watershed. • Provide uplift in water quality functions. • Improve aquatic and terrestrial habitats (complexity, quality). • Improve and maintain riparian buffer habitat. The project goals will be addressed through the following project objectives: • Implement a sustainable, reference -based, rehabilitation of the reach dimension, pattern, and profile to provide needed capacity and competency. • Support the removal of barriers to anadromous fish movement and to help improve nursery and spawning habitats. • Strategically install stream structures and plantings designed to maintain vertical and lateral stability and improve habitat diversity/complexity. • Provide a sustainable and functional bankfull floodplain feature. • Enhance and maintain hydrologic connection between stream and adjacent floodplain/riparian corridors. • Utilize the additional width of the swamp runs to provide natural filters for sediment and nutrients and diffuse flow from upstream runoff. • Install, augment, and maintain an appropriate riparian buffer with sufficient density and robustness to support native forest succession. • Encourage water quality enhancement through riparian forest planting and woody material installation, and increased floodplain interaction/overbank flooding. • Restore the existing ditched streams to single and multi -thread headwater systems with forested riparian buffers. • Provide ecologically sound construction techniques that will require minimal grading and disturbance. 3.0 PROJECT SUCCESS CRITERIA 3.1 Stream Restoration Performance Standards Single Thread Channels (Reaches 1 - 4) and Swamp Run (Reach 5): Groundwater monitoring wells are installed in and near the thalweg of all five reaches. The wells are equipped with continuous —reading gauges capable of documenting sustained flow. Per the approved Mitigation Plan, each reach must exhibit water flow for at least 30 consecutive days during years with normal rainfall (demonstrating at least Hudson Stream Restoration Project — Year 6 Monitoring Report February 2022 DMS Project # 95361 1 intermittent stream status). All restored channels shall receive sufficient flow through the monitoring period to maintain an Ordinary High -Water Mark (OHWM). Field indicators of flow events include a natural line impressed on the bank; shelving; changes in soil characteristics; destruction of terrestrial vegetation; presence of litter and debris; wracking; vegetation matted down, bent, or absent; sediment sorting; leaf litter disturbed or washed away; scour; deposition; bed and bank formation; water staining; or change in plant community. In addition, two overbank flows shall be documented for each reach during the monitoring period using continuously monitored pressure transducers and crest gauges. All collected data and field indicators of water flow shall be documented in each monitoring report. Seven flow monitoring stations are located on Reaches 1 — 4, three are located on Reach 5. 3.2 Stream Channel Restoration Stability Performance Standards Headwater System (Reach 5): All stream areas shall remain stable with no areas of excessive erosion such as evidence of bank sloughing or actively eroding banks due to the exceedance in critical bank height and lack of deep-rooted stream bank vegetation. Single Thread Channels (Reaches 1 - 4): 1. Bank Height Ratio (BHR) shall not exceed 1.2 within restored reaches of the stream channel. 2. Entrenchment Ratio (ER) shall be no less than 2.2 within restored reaches of the stream channel. 3. The stream project shall remain stable and all other performance standards shall be met through two separate bankfull events, occurring in separate years, during the 7-year post construction monitoring period. 4. Three bank pin arrays and 11 cross sections are located on Reaches 1 — 4. 3.3 Planted Vegetation Performance Standards 1. At least 320 three -year -old planted stems/acre must be present after year three. At year five, density must be no less than 260 five -year -old planted stems/acre. At year 7, density must be no less than 210 seven -year -old planted stems/acre. 2. If this performance standard is met by year 5 and stem density is trending toward success (i.e., no less than 260 five -year -old stems/acre) monitoring of vegetation on the site may be terminated provided written approval is provided by the USACE in consultation with the North Carolina Interagency Review Team (NCIRT). 3. Thirteen vegetation plot samples are located within the project area. 4.0 SITE CONDITIONS AND DESCRIPTION Much of the site has been used for crop production, primarily corn, soybeans, and wheat. As a result of the lowering of local water tables, and in some cases the complete elimination of ground and surface water interaction, the degradation of water quality and downstream anadromous fish spawning/nursery habitat has occurred. Hydric soils are present on site, meaning that the pre- existing site conditions were appropriate for raising the water table and re-establishing normal base flow conditions (See Figure 1 -Vicinity Map). 5.0 MITIGATION COMPONENTS Mitigation components are limited to five reaches: Reach 1: 833 lf; Reach 2: 5321f; Reach 3: 445 lf; Reach 4: 4371f; Reach 5: 6441f, for a total restored stream footage of 2,891 if (Table 1). Hudson Stream Restoration Project — Year 6 Monitoring Report February 2022 DMS Project # 95361 2 6.0 DESIGN APPROACH A natural design approach was used to restore channel sinuosity and flow of headwater streams, which existed prior to channelization. Grading was designed to decrease sediment load and erosion rate while allowing for floodplain connectivity and storage for overland flow. Banks were graded down to distribute flow velocity and the banks and riparian buffers were planted to stabilize the channel and create habitat. A combination of Priority 1 and Priority II restoration types were used. Where the proposed channels tie into the existing, non -restored channels, Priority II restoration was used. 7.0 CONSTRUCTION AND PLANTING TIMELINE Construction commenced in December 2014, with the installation of recommended erosion control practices, and was completed in May 2015. Planting was officially concluded in early January 2016. (Table 2 — Project History Table) 8.0 PLAN DEVIATIONS There were no significant deviations between construction plans and the As -built conditions. 9.0 PROJECT PERFORMANCE The Hudson stream restoration project is currently meeting functional goals and objectives. Annual monitoring took place in October and revealed the presence of bankfull events, floodplain connectivity, and lateral and vertical stability. In -stream structures were observed to be functioning as intended with minimal scouring of the bed or banks. Bankfull events were observed for Years 1 through Year 6. The site is meeting the bankfull standard for success. The entire length of the project is currently exhibiting fully vegetated banks with both herbaceous and woody plants. Overall, woody plantings within the riparian buffer are meeting project goals. Some dieback of planted stems occurred in previous years, but reintroduction of other woody vegetation has been noted in all monitoring plots. Tree heights range from 4-15 feet, with an approximate average of 10 feet (2020 data). Stream gauges indicated base flow and bankfull events at 9 out of 10 locations. Baseflow and bankfull events could not be confirmed at Well 10 because the well cap and logger were disturbed; the base station also malfunctioned during the monitoring effort, preventing download of the annual data. Base flow and bankfull events are assumed to have occurred based on conditions seen during monitoring and information from adjacent wells. During MY 5, bank pins could not be located due to dense vegetative growth; erosion is therefore assumed to be minimal given the vegetative stability of the reaches. Aggradation was noted on Reaches 2 and 3 in MY 5, though slightly less than in MY 3; both reaches remain stable. Stream cross sections are meeting objectives in 11 out of 11 locations. Previous corrective measures included regrading Reach 5 to raise the stream invert to create a wider swamp run. This was identified during a field meeting with NC Division of Mitigation Services and the USACE in June 2017 and completed in October 2017. A field meeting with NC Division of Mitigation Services and the USACE in April 2018, identified two monitoring wells that required repair; repair was completed. Year 1 Monitoring identified some areas where woody survivability was low; these areas were spot planted in December 2017. In Year 3, Vegetation Plot 6, and other small areas on Reach 1 and 2, appeared to have slightly low woody survivability. These areas were spot planted in October 2019, though the areas were smaller than 0.1 acres and were not included in the CCPV. No additional corrective measures are necessary. Hudson Stream Restoration Project — Year 6 Monitoring Report February 2022 DMS Project # 95361 3 10.0 METHODS AND REFERENCES Monitoring methodology did not differ from the approved Mitigation Plan. Cross-section dimensions were collected using standard survey methods. Vegetation assessment was done according to the Level 2 protocol specified by the Carolina Vegetation Survey. Hydrology monitoring wells were installed per ERDC TN-WRAP-00-02 "Installing Monitoring Wells/Piezometers in Wetlands" dated 2000. Groundwater levels were recorded using the U20- 001-01 water level data loggers manufactured by Onset Computer. The loggers were installed in the wells per the manufacturer's instructions.
