I do ask that you provide a response to comments. DWR Comments (Erin Davis): 1) DWR is concerned that this is the second year of structure and bank stability issues onsite. During the initial as -built site walk, DWR noted that many of the log structures were installed without footer logs. Was this the case with the structures proposed for repair? For the bank erosion and brush toe repairs not associated with log structures, what factors were identified in contributing to the instability? 2) DWR is also concerned with the potential soil compaction and vegetation disturbance in the newly restored riparian buffer from construction equipment. Please provide a brief plan on how the stream repair areas will be accessed in order to minimize buffer impacts and how disturbed areas will be restored. 3) Area 10 specific comment, DWR questions whether the application of bentonite would inhibit the rooting of proposed live cuttings. Can more detail please be provided on where and how bentonite is proposed for use. 2 4) Minor comment, the cover letter notes attachment of the 401 authorization, but the 401 approval letter was not included in the submittal. USACE (Casey Haywood): 5) It would be helpful if RES could provide a more complete AMP that discusses the cause(s) of the failures, and provide a more detailed description of how the failures will be addressed. It would also be important to identify access areas for the repairs and discuss how impacts to the buffer will be minimized if construction equipment is being used. 6) Providing a design sheet that shows repairs and access areas is recommended. A few photos of the failures for reference would also be helpful. 7) In the AMP, RES stated that after the maintenance activities were complete, planted areas that were heavily disturbed would be replanted- Does RES anticipate that more than 20% of the site will need to be replanted due to maintenance? Will the species used in the replanting match the original planting list? It is recommended that an additional vegetation plot is established in the disturbed area to help monitor success. Please let me know if you have any questions. Best Regards, Sam Samantha Dailey Regulatory Project Manager U.S. Army Corps of Engineers Regulatory Division 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 (919) 554-4884, Ext. 22 Samantha.j.dailey@usace.army.mil <mailto:Samantha.j.dailey@usace.army.mil> 3 fires March 25, 2021 Sam Dailey USACE — Regulatory Division 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 360o Glenwood Avenue, Suite ioo Raleigh, NC 27612 Corporate Headquarters 6575 West Loop South, Suite 300 Bellaire, TX 77401 Main: 713.520.5400 RE: Poplar Creek (SAW-2016-01985) Stream Mitigation Site — Year 2 Monitoring Adaptive Management Memo Dear Ms. Dailey, Thank you for the comments in response to the Poplar Creek (SAW-2016-01985) Stream Mitigation Site — Year 2 Monitoring Adaptive Management Memo. Below are our responses to comments and the updated Adaptive Management Plan addressing those comments. 1) DWR is concerned that this is the second year of structure and bank stability issues onsite. During the initial as -built site walk, DWR noted that many of the log structures were installed without footer logs. Was this the case with the structures proposed for repair? For the bank erosion and brush toe repairs not associated with log structures, what factors were identified in contributing to the instability? RES understands the concern and is committed to ensuring the future stability and structure issues are resolved. Observed log toe failures were behind the logs and these areas will be back filled and capped with a soil lift and livestakes. RES footers are not proposed on the log toe repairs. Causes of bank erosion has been attributed to a late livestake installation, point bars slightly higher than the outside of meanders pushing flow onto the outside bend, concentrated floodplain flow onto bank protection, and lack of properly keying in of brush toes. 2) DWR is also concerned with the potential soil compaction and vegetation disturbance in the newly restored riparian buffer from construction equipment. Please provide a brief plan on how the stream repair areas will be accessed in order to minimize buffer impacts and how disturbed areas will be restored. RES intends to minimize soil compaction and vegetation disturbance in the newly restored buffer as much as possible. In response to both DWR's concern and USACE's concern in comment 5 and 6 the potential limit of disturbance with the access areas is included in the Figures below. The access areas have been developed with the goal to minimize buffer impacts and have been walked with the construction superintendent to ensure our goals of minimal impact are aligned. The disturbed areas will be restored by reseeding with a combination of temporary and permanent seed mix and then planting bare root trees and livestakes where necessary. 3) Area 10 specific comment, DWR questions whether the application of bentonite would inhibit the rooting of proposed live cuttings. Can more detail please be provided on where and how bentonite is proposed for use. Area 10 has been revised to call for the installation of a new log toe and no longer using bentonite. res.us 4) Minor comment, the cover letter notes attachment of the 401 authorization, but the 401 approval letter was not included in the submittal. Apologies, the 401 approval letter is now included. USACE (Casey Haywood): 5) It would be helpful if RES could provide a more complete AMP that discusses the cause(s) of the failures, and provide a more detailed description of how the failures will be addressed. It would also be important to identify access areas for the repairs and discuss how impacts to the buffer will be minimized if construction equipment is being used. Additional details on our best guess as the causes of the failures as well as additional descriptions of how the failures will be addressed were added to the Adaptive Management Plan and design sheets with additional details were also provided. We provided the access area locations in the Figures with the goal to minimize buffer impacts. 6) Providing a design sheet that shows repairs and access areas is recommended. A few photos of the failures for reference would also be helpful. Design sheet and photos have been added for reference. To provide an overview of the access area and show the entirety of it, the limits of disturbance has been provided in the figures. 7) In the AMP, RES stated that after the maintenance activities were complete, planted areas that were heavily disturbed would be replanted- Does RES anticipate that more than 20% of the site will need to be replanted due to maintenance? Will the species used in the replanting match the original planting list? It is recommended that an additional vegetation plot is established in the disturbed area to help monitor success. RES does not anticipate more than 20% of the site will need to be replanted due to maintenance. based on the plans only 4.5% of the site could be impacted, as the limit of disturbance is about 0.54 acres. To the extent practical the construction team plans to avoid the more established trees onsite. We intend to plant three species from the original planting list: American sycamore, willow oak, and swamp chestnut oak. Additionally, due to availability of trees harvested this year, we would like to propose adding an extra species: common buttonbush. We believe this species will do well at the site and is a native species in the piedmont alluvial forest which is the targeted community for this site. Per recommendations, RES will add a random vegetation plot in the disturbed areas to help monitor success of the disturbed areas. 2 Poplar Creek Year 2 Adaptive Management Plan During Year 1 (2020) monitoring activities performed September 2020, RES observed a number of failing log toe structures and areas of bank erosion on YB1-C and a few bank erosion areas on YB2-B (see Figures). The log toes were from the original construction and were functioning properly during the as - built repairs that occurred in the winter of 2019/2020. However, they begun to show signs of failing in the late summer, early fall of 2020. The failing log toes and bank erosion areas will be repaired with a combination of minor bank grading, coir matting, livestake installation, sod mats, coir logs, and/or brush toes. RES engineers visited the site in January 2021 and compiled a list of 15 structures/areas that needed some form of repair. These repair areas are outlined below and correspond by number with the attached maps. After maintenance activities are completed, planted areas that were heavily disturbed will be replanted. Upon approval of this plan, RES would like to conduct these maintenance activities in March or April of 2021. Outside of this adaptive management plan, other maintenance activities that will be conducted this year include the replanting of the 0.77-acre area in and around VP4 during the dormant season and continued invasive treatments with aquatic safe herbicide in the YB2-A channel YB1-C Area 1 Issue: Erosion behind a log toe structure. Cause: Livestake mortality. Treatment: Backfill the eroded area with a straw bale and cap the area with matted soil lift and live cuttings. Area 2 Issue: Erosion behind a log toe structure. Cause: Livestake mortality. Treatment: Backfill area eroding away with rock, cap with matted soil lift and live cuttings. Area 3 Issue: Brush toe washed out. Cause: Inadequate brush toe key -in. Treatment: Grade bank back, mat, and livestake. Area 4 Issue: Bank erosion. Cause: Point bar grading slightly higher elevation than outside meander. Treatment: Grade point bar to allow for more flow through channel and livestake and mat graded area. Area 5 Issue: Brush toe washed out. Cause: Inadequate brush toe key -in. Treatment: Replace brush toe. Cap with soil lift and live cuttings. Area 6 Issue: Damaged log toe. Cause: Improper installation. Treatment: Replace with brush toe. Cap with soil lift and live cuttings. o 3 Area 7 Issue: Brush toe washed out. Cause: Inadequate brush toe key -in. Treatment: Grade bank back, mat, and livestake. Area 8 Issue: Damaged log toe and bank erosion. Cause: Improper installation and grading point bar at a higher elevation than outside meander. Treatment: Grade point bar, mat and livestake. Replace log toe with a shorter log to widen pool. Backfill with Class B/I rock. Cap with matted soil lift and live cuttings. Area 9 Issue: Bank erosion and damaged log toe. Cause: Improper installation and grading point bar at a higher elevation than outside meander. Treatment: Grade point bar, mat and livestake. Replace log toe with brush toe. Cap with soil lift and live cuttings. Area 10 Issue: Bank erosion around log sill. Cause: Lack of compaction on log sill backfill and livestake mortality Treatment: Install new log toe. Area 11 Issue: Bank erosion. Cause: Lack of compaction on log sill backfill and livestake mortality. Treatment: Notch the left side of the log sill. Rebuild bank with Class B/I rock. Cap with matted soil lift and live cuttings. Area 12 Issue: Bank erosion. Cause: Livestake mortality. Treatment: Grade point bar, mat and livestake. Area 13 Issue: Bank erosion. Cause: Wrong angle on log sill. Treatment: Notch the left side of the log sill. Add brush toe. Cap with matted soil lift and live cuttings. 4 YB2-B Area 14 Issue: Bank erosion. Cause: Lack of compaction on log sill backiill. Treatment: Rebuild bank with Class B/I rock. Cap with matted soil lift and live cuttings. Area 15 Issue: Bank erosion. Cause: Improper key in of log sill. Treatment: Key in grade control a minimum of 5 feet into the bank. The approved Erosion and Sediment Control (ESC) permit from the original construction remains open and should permit for the work that is required if needed and is attached. Regarding 401/404 permitting, RES believes that the proposed work falls within the treatment outlined in the approved Final Mitigation Plan which has not expired at this time. The original 404/401 authorizations from the approved mitigation plan are also attached. Example photos: Area 15 Bank erosion.

In addition, the Corps has issued a Nationwide Permit 27 (NWP 27) verification letter authorizing work in waters of the United States associated with restoration of aquatic resources on the mitigation bank site. As bank sponsor you are required to comply with the approved Neu -Con UMBI, Final Mitigation Plan —Poplar Creek Mitigation Site, the terms and conditions of your NWP 27 verification letter, and the Corps' regulations regarding compensatory mitigation (33 CFR 332). The bank sponsor accepts all risk, liability, and responsibility for the success of all mitigation activities associated with the approved mitigation bank site. In accordance with the final mitigation plan, the bank sponsor must prepare and submit annual monitoring reports to document whether the stream (4,273 linear feet) restoration and enhancement areas on the project site meet the necessary interim and final performance standards. When credits are debited from the mitigation site, the bank sponsor must provide the Corps with an updated ledger form identifying the purchaser of the credits, the project name, the permit number, and the number and type of credits to be debited. When all stream (3,926 stream mitigation units (SMUs)) credits have been consumed, no more credits may be sold from this mitigation site. From the Corps' perspective, the next phase in the establishment of the Neu -Con UMBI, Poplar Creek Mitigation Bank, includes recording the conservation easement to protect the mitigation site, marking the boundary of the site with permanent signs, and executing the necessary financial assurances. Once the conservation easement has been recorded and we receive the required executed financial assurance documents, the Corps will be in a position to approve an initial credit release for 15% of the total stream restoration and enhancement mitigation credits. We look forward to working with you to ensure the Poplar Creek Mitigation Site complies with the requirements of the approved UMBI and site -specific mitigation plan. In all future correspondence concerning this matter, please refer to our file number, SAW- 2016-01985. If you have any questions regarding this letter, the mitigation plan review process, or the requirements of the Mitigation Rule, please contact Ms. Samantha Dailey by email at Samantha.J.Dailey@usace.army.mil or by phone at (919) 554-4884 extension 22.

Preliminary Determination X There are waters, including wetlands, on the above described project area, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters, including wetlands, have been delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. Therefore this preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33 CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district for further instruction. There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act (CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the waters, including wetlands, have not been properly delineated, this preliminary jurisdiction determination may not be used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands, at the project area, which is not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. B. Approved Determination _ There are Navigable Waters of the United States within the above described property subject to the permit requirements of Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC § 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ There are waters of the U.S., including wetlands, on the above described project area subject to the permit requirements of Section 404 of the Clean Water Act (CWA) (33 USC § 1344).

As the Corps may not be able to accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps. _ The waters of the U.S., including wetlands, on your project area have been delineated and the delineation has been verified by the Corps. We strongly suggest you have this delineation surveyed. Upon completion, this survey should be reviewed and verified by the Corps. Once verified, this survey will provide an accurate depiction of all areas subject to CWA jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied upon for a period not to exceed five years. _ The waters of the U.S., including wetlands, have been delineated and surveyed and are accurately depicted on the plat signed by the Corps Regulatory Official identified below on . Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ There are no waters of the U.S., to include wetlands, present on the above described project area which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. _ The property is located in one of the 20 Coastal Counties subject to regulation under the Coastal Area Management Act (CAMA). You should contact the Division of Coastal Management in Morehead City, NC, at (252) 808-2808 to determine their requirements. Placement of dredged or fill material within waters of the US, including wetlands, without a Department of the Army permit may constitute a violation of Section 301 of the Clean Water Act (33 USC § 1311). Placement of dredged or fill material, construction or placement of structures, or work within navigable waters of the United States without a Department of the Army permit may constitute a violation of Sections 9 and/or 10 of the Rivers and Harbors Act (33 USC § 401 and/or 403).

Date: February 11, 2019 ® Field Determination. Date(s): June 22, 2017 1. The Corps of Engineers believes that there may be jurisdictional aquatic resources in the review area, and the requestor of this PJD is hereby advised of his or her option to request and obtain an approved JD (AJD) for that review area based on an informed decision after having discussed the various types of JDs and their characteristics and circumstances when they may be appropriate. 2. In any circumstance where a permit applicant obtains an individual permit, or a Nationwide General Permit (NWP) or other general permit verification requiring "pre -construction notification" (PCN), or requests verification for a non -reporting NWP or other general permit, and the permit applicant has not requested an AJD for the activity, the permit applicant is hereby made aware that: (1) the permit applicant has elected to seek a permit authorization based on a PJD, which does not make an official determination of jurisdictional aquatic resources; (2) the applicant has the option to request an AJD before accepting the terms and conditions of the permit authorization, and that basing a permit authorization on an AJD could possibly result in less compensatory mitigation being required or different special conditions; (3) the applicant has the right to request an individual permit rather than accepting the terms and conditions of the NWP or other general permit authorization; (4) the applicant can accept a permit authorization and thereby agree to comply with all the terms and conditions of that permit, including whatever mitigation requirements the Corps has determined to be necessary; (5) undertaking any activity in reliance upon the subject permit authorization without requesting an AJD constitutes the applicant's acceptance of the use of the PJD; (6) accepting a permit authorization (e.g., signing a proffered individual permit) or undertaking any activity in reliance on any form of Corps permit authorization based on a PJD constitutes agreement that all aquatic resources in the review area affected in any way by that activity will be treated as jurisdictional, and waives any challenge to such jurisdiction in any administrative or judicial compliance or enforcement action, or in any administrative appeal or in any Federal court; and (7)whether the applicant elects to use either an AJD or a PJD, the JD will be processed as soon as practicable. Further, an AJD, a proffered individual permit (and all terms and conditions contained therein), or individual permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331. If, during an administrative appeal, it becomes appropriate to make an official determination whether geographic jurisdiction exists over aquatic resources in the review area, or to provide an official delineation of jurisdictional aquatic resources in the review area, the Corps will provide an AJD to accomplish that result, as soon as is practicable. This PJD finds that there "may be" waters of the U.S. and/or that there "may be" navigable waters of the U.S. on the subject review area, and identifies all aquatic features in the review area that could be affected by the proposed activity, based on the following information: SUPPORTING DATA.
