The accompanying submittal has been revised to reflect our responses to all comments and all information requested. Below are Ecotone’s responses below to the received comments. 1. Section 9.0 a. A sentence states that “Year 3 Monitoring identified some areas where woody survivability was low; these areas were spot planted in October 2019.” These areas were not identified in the MY3 report. Please identify the area(s) of low stem density on the CCPV. ECOTONE RESPONSE: Only Vegetation Plot 6 and a few smaller areas along Reach 1 and 2 were identified as having marginally low woody survivability. These areas did not meet the threshold for inclusion in the CCPV and therefore were not included in Year 3 or Year 4. The report text has been revised. 2. Appendix B, a. Table 6 – See comment 1 above. Please verify whether the low stem density area(s) trigger any thresholds for inclusion in this table. ECOTONE RESPONSE: The areas spot planted were not greater than 0.1 acres, and therefore were not included in the CCPV. A note has been added to Table 6. 3. Appendix E a. Table 9 – The verification of bankfull events table should be cumulative showing prior years. b. Table 12 – Please verify that Well 8 (Reach 5) achieved 30 consecutive days of flow. c. Figure 10 – See “b” above. Please verify that Well 8 (Reach 5) achieved 30 consecutive days of flow. It may be beneficial to call out with arrows and dates on the chart where 30 consecutive days was identified. ECOTONE RESPONSE: Table 9 has been updated to include previous years’ data. Well 8 on Reach 5 did have 30 consecutive days of flow. Though water occasionally dropped below the streambed elevation for a few hours, each day between 1/21/19 and 3/21/19 did have some flow. Figure 10 was updated with a note to identify that period of consecutive flow. Hudson Year 4 - Response to Comments January 10, 2020 Page 2 of 3 4. Digital Files a. Geodatabase features do not all match creditable assets. DMS needs representative features for Reach 2 and Reach 4 ECOTONE RESPONSE: As per our email communication, the geodatabase includes files for the stream alignments as designed.

It is located in Beaufort County, NC and the Tar-Pamlico River Basin. 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 4 monitoring was completed in October 2019. 2.0 PROJECT GOALS AND OBJECTIVES The project goals of the Hudson property 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 appropriate riparian buffer with sufficient density and robustness to support native forest succession. • 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 intermittent stream status). All restored channels shall receive sufficient flow through the Hudson Stream Restoration Project – Year 4 Monitoring Report FINAL January 2020 DMS Project # 95361 2 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 The Hudson property is 13.49 acres located in Beaufort County, NC and the Tar-Pamlico River Basin. The majority of the site is 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 and 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: 532 lf; Reach 3: 445 lf; Reach 4: 437 lf; Reach 5: 644 lf, for a total restored stream footage of 2,891linear feet (Table 1). Hudson Stream Restoration Project – Year 4 Monitoring Report FINAL January 2020 DMS Project # 95361 3 6.0 DESIGN APPROACH A natural design approach was used to restore the natural sinuosity and flow of the headwater streams which existed prior to channelization. Grading was done 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 channel’s banks or bed. Bankfull events were observed Year 1 through Year 4 monitoring. 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 with some dieback of planted stems and introduction of other woody vegetation in 12 out of 13 vegetation monitoring plots. Year 1 Monitoring identified some areas where woody survivability was low; these areas were spot planted in December 2017. Stream gauges indicated base flow and bankfull events at 10 out of 10 locations. 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, however both reaches remain stable. Stream cross sections are meeting objectives in 11 out of 11 locations. A field meeting with NC Division of Mitigation Services and the USACE in June 2017, identified corrective measures necessary on Reach 5 to raise the stream invert to create a wider swamp run. Regrading was 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. In Year 3, Vegetation Plot 6 and some other small areas on Reach 1 and 2 appeared to have slightly low woody survivability. These areas were spot planted in October 2019; these areas were smaller than 0.1 acres and were not included in the CCPV. No additional corrective measures are necessary; monitoring will continue as scheduled. 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.

Monitoring Data - Dimensional Morphology Summary (Dimensional Parameters – Cross Sections) Project Name/Number (Hudson/ DMS:95361) Segment/Reach: Reach 1-4 (2200 feet) Cross Section 1 (Pool - Reach 3)Cross Section 2 (Riffle - Reach 3)Cross Section 3 (Riffle - Reach 4)Cross Section 4 (Pool - Reach 4)Cross Section 5 (Pool - Reach 2) Note: The smaller the channel the closer the survey measurements are to their limit of reliable detection, therefore inter-annual variation in morphological measurement (as a percentage) is by default magnified as channel size decereases. Some of the variability above is the result of this factor and some is due to the large amount of depositional sediments observed. Cross Section 6 (Riffle - Reach 2)Cross Section 7 (Pool - Reach 1)Cross Section 8 (Riffle - Reach 1)Cross Section 9 (Pool - Reach 1)Cross Section 10 (Riffle - Reach 1) Cross Section 11 (Confluence - Reach 1)The above morphology parameters reflect the 2018 guidance that arose from the mitigation technical workgroup consisting of DMS,the IRT and industry mitigation providers/practitioners. The outcome resulted in the focus on three primary morphological parameters of interest for the purposes of tracking channel change moving forward. They are the bank height ratio using a constant As-built bankfull area and the cross sectional area and max depth based on each years low top of bank. These are calculated as follows: 1 -Bank Height Ratio (BHR) takes the As-built bankful area as the basis for adjusting each subsequent years bankfull elevation. For example if the As-built bankfull area was 10 ft2, then the MY1 bankfull elevation would be adjusted until the calculated bankfull area within the MY1 cross section survey = 10 ft2.The BHR would then be calculated with the difference between the low top of bank (LTOB) elevation for MY1 and the thalweg elevation for MY1 in the numerator with the difference between the MY1 bankfull elevation and the MY1 thalweg elevation in the denominator. This same process is then carried out in each successive year. 2 -LTOB Area and Max depth -These are based on the LTOB elevation for each years survey (The same elevation used for the LTOB in the BHR calculation). Area below the LTOB elevation will be used and tracked for each year as above. The difference between the LTOB elevation and the thalweg elevation (same as in the BHR calculation) will be recroded and tracked above as LTOB max depth. Note: Year 4 Monitoring did not require Cross Section Survey. Table is based on 2018 information.
