Having reviewed your letter and referenced plans, I am providing the following responses regarding each Compliance Site originally listed in my email dated 7/2/2020: Compliance Site 1: The Corps is generally agreeable to your proposal to leave the check dam in place at its current location until the site has reached a more stabilized state. However, we require the following additional information: 1) Your letter does not specify whether you propose to restore the stream to pre -grading conditions, or request consideration via after -the -fact permitting to stabilize the site in a different state. Please provide this information, including the timeframe for submitting a specific restoration plan (including a completion date) or after -the -fact permitting request; Compliance Sites 2 and 3: no further action required from the Corps. Compliance Site 4: The Corps is generally agreeable to your proposal to "complete the re -work in this area." It is our understanding that you will restore the stream to pre -grading conditions, and that you require 3-4 days of suitable weather conditions to complete the work. However, we require the following additional information: 1) Please provide the "as built" survey of the fill slope for this area, showing the reach of stream impacted outside of permitted limits; 2) Please provide a specific restoration plan (including an estimated completion date), including how you propose to return the area to pre -grading conditions (i.e. grade and contour), and how you plan to stabilize the area using native vegetation and/or natural channel design structures; Compliance Site 5: The Corps is generally agreeable to your stream and wetland restoration proposal in this area. However, we require the following additional information/considerations: 1) We are concerned about the highly erodible nature of soils in the proposed work area. Have you considered whether or not the proposed sill structures are appropriate/sufficient to prevent the stream/water from simply working around the structures? 2) The last (i.e. most downstream) structure shows a —2' drop into the receiving steam. Typically we would not expect more than a 1' vertical drop between structures and/or the receiving stream bed in this region. Could the restoration plan be amended to accommodate this shorter vertical drop? 3) Please provide an estimated completion date; Compliance Site 6: no further action required from the Corps. Please provide the above requested information within 2 weeks of the date of this email, and let me know if you have any questions. Sincerely, Dave Bailey David E.

SENT VIA EMAIL September 3, 2020 Mr. David Bailey Wilmington District, Corps of Engineers 69 Darlington Avenue Wilmington, NC 28403-1343 RE: Action ID: SAW-2018-00240 (email response 08.20.20) Dear Mr. Bailey, The following is our response to your email of August 20, 2020 requesting additional information for the below items: Compliance Site 1 Question: Your letter does not specify whether you propose to restore the stream to pre -grading conditions, or request consideration via after -the -fact permitting to stabilize the site in a different state. Please provide this information, including the timeframe for submitting a specific restoration plan (including a completion date) or after -the -fact permitting request. Response: Plateau will restore the stream to pre -grading conditions. It is our intent to perform an as -built prior to construction. Any disturbance if past the LOD will be removed. The original existing conditions will be staked. It is the intent to restore the existing ground to pre -disturbed condition with riparian seed and a coir fiber mat. If Live Stakes are required, then work will have to proceed after November 15t and before March 15t when those planting go dormant. Given the current time of year the FOR would suggest planting wetland sedge plugs at a density of 2ft on center along the soil lifts and along the streambanks of the restored channel. A repair condition as -built will be provided when the work is complete. Plateau can perform this work within a 3-4 day window of consistent dry weather. Plateau will be performing this scope under the guidance of an Environmental Engineer from Wildlands Engineering and Central Carolina Seeding. Compliance Site 4 Question: The Corps is generally agreeable to your proposal to "complete the re -work in this area." It is our understanding that you will restore the stream to pre -grading conditions, and that you require 3-4 days of suitable weather conditions to complete the work. However, we require the following additional information: 1) Please provide the "as built" survey of the fill slope for this area, showing the reach of stream impacted outside of permitted limits; Response: As -Built Survey is accompanying this letter. gray.com 10 Quality Street T: 859.281.5000 Lexington, KY F: 859.252.5300 Mr. David Bailey September 3, 2020 Page 2 2) Please provide a specific restoration plan (including an estimated completion date), including how you propose to return the area to pre -grading conditions (i.e. grade and contour), and how you plan to stabilize the area using native vegetation and/or natural channel design structures; Response: Plateau will restore the stream to pre -grading conditions. It is our intent to perform an as -built prior to construction. Any disturbance if past the LOD will be removed. The original existing conditions will be staked. It is the intent to restore the existing ground to pre -disturbed condition with riparian seed and a coir fiber mat.

Plateau will be performing this scope under the guidance of an Environmental Engineer from Wildlands Engineering and Central Carolina Seeding Compliance Site 5: The Corps is generally agreeable to your stream and wetland restoration proposal in this area. However, we require the following additional information/considerations: 1) We are concerned about the highly erodible nature of soils in the proposed work area. Have you considered whether or not the proposed sill structures are appropriate/sufficient to prevent the stream/water from simply working around the structures? Response: From Timmons Engineering (EOR): To provide the corps with a greater level of comfort, the sills can be installed with clay plugs. Clay plugs will create a barrier for the water, pushing it up to the surface where the water will daylight in the channel. Plateau is following the direction and engineered plans from Timmons Engineering for this work along with supervision from an Environmental Engineer from Wildlands Engineering and Central Carolina Seeding. A detail has been added to the revised plans (accompanying this letter) to show the installation of the clay plug and location. 2) The last (i.e. most downstream) structure shows a —2' drop into the receiving steam. Typically, we would not expect more than a 1' vertical drop between structures and/or the receiving stream bed in this region. Could the restoration plan be amended to accommodate this shorter vertical drop? Response: From Timmons Engineering (EOR): The tributary restoration is tying into an incised channel along the main reach. Due to the incision and a channel of this size it will be more stable along the left and right banks of the tributary to have a 2 ft drop into the main channel. The amount of energy from the tributary will not negatively affect the main channel due to their vast size differences. Without restoring the main channel, we feel this is the best approach. Stability of the left and right banks of the tributary will be key in this area. The last rock sill has been extended to provide added boulder toe protection along the main channel. Mr. David Bailey September 3, 2020 Page 3 3) Please provide an estimated completion date. Response: This is very dependent on the start date which needs to be considered when clear weather is available along with dormant conditions if Live Plantings are being used. The current time frame given from two environmental sources is 3-4 weeks to complete. Plateau will be performing this scope under the guidance of an Environmental Engineer from Wildlands Engineering and Central Carolina Seeding to efficiently complete the work to the satisfaction of the ACOE. Plateau is prepared to expedite the work as soon as a clear weather path is provided and all design conditions are known. Our entire team is committed to maintaining compliance with the Department of the Army (DA) permit and continues to work diligently to address any matters on a timely basis. Should you have any questions, please contact Mr. Kevin Wurschmidt via telephone at (859) 314-2715 or email (kwurschmidt@gray.com).
