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. Page 9 of 9 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, 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 NCWRP 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.ne.us/ncwetlands/strmgide.htn1. 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, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal" of a PCN.

It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). O Applicant/Agent's Signature Date (Agent's signature is valid only if an authorization letter from the applicant is provided.) Page 12 of 12 Additional Information 111. 9. The site is a small stream, an unnamed tributary of Mud Creek, located on our property at 2732 Kanuga Road. The stream is below a grassy yard below our home. (Please see attached site plan.) Work began to remove sediment build-up from stream and to begin construction of a small pond before we learned that the work required permitting. Silt fences for sediment control were deployed prior to beginning work and, at the recommendation of Mr. Kevin Barnett of the NC Division of Water Quality, temporary stone check dams have been installed where requested. Excavated silt and soil have been spread over a level grassy area of our yard adjacent to the site where we hope to construct the pond. The general land use in the vicinity of the project is the residential subdivision of Beaumont Estates, of which our lot and the proposed pond site is a part. III. 10. The project we request approval for is to cleanout silt/sediment deposited from upstream of our property and to construct a small pond as an aesthetic, recreational, fish and wildlife feature to our home. We propose excavating with a backhoe to remove collected sediment and to create a pond (please see attached site plan) and also to use a bulldozer to spread the removed sediment and soil to create a dam. The remainder of the removed sediment and soil would be spread on a level yard area adjacent to the proposed pond and the dam and yard area would be sewn in grass. Compacted clay soil would be used for a core of the dam and soil from the pond excavation would be used to encase the core. A standard flanged overflow pipe of 12" diameter and in' L" shape would be used to allow water at the pond to enter and spill out back into the stream at the stream's current location. A gate valve in the pipe is proposed for drawing down the pond if necessary. Additionally, a 36" pipe for emergency overflow would be installed adjacent to the 12" pipe, at the current stream flow, and also an 8' swale would be created at the top of the dam for additional emergency overflow. The banks of the pond and dam and all adjacent disturbed areas would be returned to grass immediately upon completion of work. Work is proposed to be completed in approximately three weeks upon obtaining required permits, weather permitting. III. 11. The purpose of the project is to remove very unsightly sediment build-up from the stream, to beautify our backyard and to provide a pond for recreational use and for fish and waterfowl. We believe the site would also provide a benefit of preventing silt that enters the stream from upstream of our property from continuing downstream. VI. 1. Proposed impacts include removing sediment/silt and excavating for a small pond with a backhoe in and adjacent to the stream (Please see attached site plan) and placing removed sediment and soil for the creation of a dam and placing pipes for overflow. Excavated sediment and soil would be spread with a bulldozer at the dam and on adjacent yard area. Impact also includes the installation of temporary silt fencing downgrade from the disturbed areas and the installation of temporary check dams where instructed. VI. 5. Pond Creation: The pond site is proposed to be excavated with a backhoe to remove collected sediment and to create the pond (please see attached site plan) and a Additional Information Continued bulldozer is proposed to be used to spread the removed sediment and soil to create a dam. The remainder of the removed sediment and soil would be spread on a level yard area adjacent to the proposed pond and the dam and yard area would be sewn in grass. Compacted clay soil would be used for a core of the dam and soil from the pond excavation would be used to encase and cover the core. A standard flanged overflow pipe of 12" diameter and in "L" shape would be used to allow water at the pond surface to enter the pipe and spill out back into the stream at the stream's current location. A gate valve in the pipe is proposed for drawing down the pond if necessary. Additionally, a 36" pipe for emergency overflow would be installed adjacent to the 12" pipe at the current stream flow and also an 8' swale would be created in the dam for additional emergency overflow. The banks of the pond and dam and all adjacent disturbed areas would be returned to grass immediately upon completion of work. VII. Creation of the pond and cleanup of the sediment from the stream will greatly improve the aesthetics of the site and overall property value of our home, which has been degraded by large amounts of sediment which has collected on our property and which has come from other properties upstream. We believe the work proposed will also serve to reduce downstream sediment buildup. Additionally, the pond will create a recreation area for our family and will be a habitat for fish and other aquatic life and for waterfowl. To reduce impact during and after construction and until planted grass will hold soil, we will maintain silt fencing, temporary check dams, and other recommended sediment and erosion control measures in place for as long as is appropriate to preserve water quality. Additionally, we will work diligently to complete the project rapidly to help reduce impacts to as short a time as we can. We intend to be responsible stewards of our land and stream and will follow the recommendations and requirements given us to reduce impact during and after construction and we will maintain the site to keep appropriate grass and vegetation in place to hold soil afterwards. 2 W 2 I- w W N E 13 o N N 'Q ? n o n -N V, a (`I Tv 40 va?O1D v,?3o ?,N?Q 6 C } N N ' }3 w AU)>0 ?
