Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. r Page 9 of 12 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect .open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http:!/h2o.enr.state nc us/ncwetlandsistrm 'd~ e lltinl. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g,, deed restrictions, conservation easement, e1c;.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. 2.

We are in the process of requesting a revision to the previously approved 401 permit for Stonewater Subdivision from the previously approved 120' of stream impact to 149.5' which is less than the maximum threshold of 150'. This is an effort to address additional impacts in excess of the requested revised 401 permit and bring the site into compliance. Total impacts stream impacts are 180 feet. We would ask that you approve this stream restoration plan in excess of the maximum stream impacts allowed by the 401 permit knowing that the extra impacted stream area was a result of the severe erosion that occurred during a heavy rain event (8" in a 4 hour period) and Wake County's Environmental Services staff demand that Mr. Marshburn add rip rap to all the eroded area in the stream and buffer to achieve immediate site stabilization. The additional area was cleared during the installation of this rip rap. Proposed Restoration Plan The original construction plan called for a piped stream crossing of 100 feet plus headwall wings and a 40 foot long dissipater required by Wake County Environmental Services. In addition a heavy rain event occurred during the installation of the cross drainage pipes and the subsequent stabilization efforts impacted another 36 feet for a total impact of 180 feet Our plan is to revise the original permit ftom the approve 120 feet to 149.5 feet and restore the balance of the impacted stream to a natural stabilized channel. We would propose a plan to return the 31 foot portion of the stream in excess of the requested 149.5 feet to a stabilized channel naturally vegetated stream. The proposal is to remove any rip rap from the stream channel in excess of the 149.5' requested impact and to restore the stream banks and channel to a stabilized corridor to facilitate the passage of aquatic life. The Wake County Environmental Services approved construction plan requires a velocity dissipater for the twin RCP culvert pipes of 40 foot wide by 40 foot long and 27 inches deep of class one rip rap. The current pipe crossing from outside the edge of the upstream wing wall to the edge of the down stream headwall is 104 feet. Adding the 40 foot dissipater from the invert out of the pipe (edge of head wall) would bring the impact to 144 feet. The rip rap at that point is about 12"deep. The rip rap will be removed from the channel for another 5 feet progressively being thinner until it is at the elevation of the original stream channel bottom. This will be at a point within the revised 149.5 foot 401 permit. The channel from that point to the existing undisturbed channel will be restored. Bio-degradable rolled erosion control matting installed below the water level to temporally stabilize the area and prevent channel erosion until vegetation establishes in the stream channel to stabilize the area. The bank side slopes will be seeded with a native riparian seed mix and stabilized with a bio degradable coconut fiber erosion control matting (North American Green C-350).The area will be monitored for stabilization and corrective actions taken if any bank erosion occurs. Summary: We would ask that you approve this proposal to facilitate bringing this area into compliance and stabilizing the stream channel. Considering the situation and the end result of a stable section of stream we would ask for your approval of this restoration plan. Any guidance for site compliance would be appreciated. Please let us know in a documented response as to any issues you have with our restoration efforts. Sincerely, Jake Taylor, CPESC #3602 Pollution Monitoring Services Inc.

After discussion with NC DWQ staff it has become evident that part of the request could not be considered as it conflicted with DWQ policy. The previous response for site compliance on Item # 4 on Notice of Violation # 2007-0241 was as follows: Item# 4: The stream impacts beyond what was authorized in your 401 Water Quality Certification, must be restored to the original pattern profile and dimension. Otherwise you must request that your 401 Water Quality Certification be modified. How Item # 4 is to be addressed: • Mr. Neal Floyd is currently pursuing the requirements for the revised 404 permit thru the Corp of Engineers and the revised 401 permit thru Division of Water Quality staff for Mr. Marshburn. This request will be asking for revised maximum stream impacts allowed. Miti a~payment review will be requested for any additional impacts over the allowed maximum stream impacts. • The 12 foot well easement impact to the upper stream channel has been returned to the original profile and efforts to stabilize the area are in progress (see above). Replanting of the buffer easement (approximately 18 trees) will have to wait until this fall for survival. Currently volunteer trees are covering most of the area as the well easement was abandoned over a year ago. • The impacted stream and riparian buffer will be monitored for the next several years to make sure the vegetation survives and is replanted if necessary, the level spreaders function properly, and the area is stabilized. After discussion with NC DWQ staff it has become evident that a request for the partial mitigation for the 30 feet of impacted stream in excess of the maximum 150' feet allowed by 401 permit approval would not be considered. Below is the proposed revision to that response dealing with issues addressed in the first bullet: Addendum: Item # 4 states that the "The stream impacts beyond what was authorized in your 401 Water Quality Certification, must be restored to the original pattern profile and dimension. Otherwise you must request that your 401 Water Quality Certification be modified." We are in the process of requesting a revision to the previously approved 401 permit from the approved 120' of stream impact to 149.5' which is less than the maximum threshold of 150'. Mr. Neal Floyd will be pursuing this revised permit with Mr. Ian McMillan. We would then propose a plan to return the 31 foot portion of the stream in excess of the requested 149.5 feet to a stabilized channel naturally vegetated stream. The existing stream channel has vertical walls with eroding banks as the stream is trying to resize itself because of increased storm water runoffs. It would be impractical to return the stream impacts to that design as it would not be stable and would continue to erode like portions of the existing channel. The result would be continued stream decay and sediment deposition in the stream channel. DWQ allows stream restoration projects under Certification # 3495 to convert unstable and degraded stream corridors to natural stable conditions. We understand that this Certification does not usually apply to sites under violation, but we would propose restoring the section of impacted stream channel to a more stable stream corridor than the existing degrading upstream channel. The restoration of the stream channel would involve a transition of width and bank slope from the approved impact stream area to the existing stream corridor profile with a more stable channel design. This would not be to the original profile and dimension of the original stream profile as it was unstable and decaying. The end resulting restored channel in the impacted transition area would have a wider flood plain with a sinuous vegetated stream channel and flatter bank slopes and would remain stable in heavy storm events. Currently the channel has rip rap in the stream bed for most of the impacted length. In the 30 foot area upstream of the culvert headwall, rip rap will be removed manually to below the water elevation with minimal disturbance to the newly re-established vegetation. The stream banks have already been stabilized with matting and a riparian seeding. In the down stream section of the impacted area below the headwalls rip rap will be removed below the velocity dissipater. Rolled turf reinforcement matting (North American Green C-350) cross vanes and log J-hook vanes would be incorporated into the design as the channel is transitioned into the existing stream channel. We would prefer installing offset rock vanes instead of the log vanes, but are unsure that you would allow the use of rip rap to build these structures. The entire area will then be seeded with a natural riparian seed mixture obtained from Mellow Marsh Farm. Any exposed area will be reinforced with the C-350 matting which would have the same shear stress of class 2 rip rap. Log vanes would be installed over the matting to dissipate the stream flow and ad sinuosity to the stream channel. This would improve the quality of that section of the stream channel, slow the stream velocities and hopefully stop some of the downstream incising of the stream channel. A small temporary rip rap check dam (several courses of class 1 rip rap) would be placed at the downstream edge of the impacted area to help stabilize the area until stream channel and bank vegetative growth is established. When the stream bed is stabilized with deep rooted vegetation this in stream check dam would be removed. Summary: We would ask that you approve this proposal knowing that the extra impacted stream area was not planned but done as a result of the severe erosion that occurred during a heavy rain event (8" in a 4 hr period) and Wake County's Environmental Services staff demand that Mr. Marshburn add rip rap to all the eroded area in the stream and buffer to achieve immediate site stabilization. The additional area was cleared during the installation of this rip rap. Mr. Marshburn did not plan the additional stream impacts and has gone to great effort to bring the site into compliance. Considering the situation and the end result of a stable section of stream we would ask for your approval of this restoration plan. Any guidance for site compliance would be appreciated. Please let us know in a documented response as to any issues you have with our restoration efforts. Sincerely, Jake Taylor, CPESC #3602 Pollution Monitoring Services Inc.
