Dehart 4830 Byers Road Alpharetta, GA 30022 Subject Property: Dehart Farm Pond Ut to Tobacco Branch [040402, 2-116, C] WAIVER of 401 Water Quality Certification Dear Mr. Dehart: Your application dated March 16, 2006, for a 401 Water Quality Certification was received in the Central Office on March 30, 2006, with more information received from you on June 6, 2006. According to our rules [15A NCAC 2H .0507 (A)], if final action is not taken within 60 days, the Certification is waived unless DWQ has objected in writing to your application. Therefore, DWQ has waived the requirement for a 401 Water Quality Certification for your plans to permanently impact 300 linear feet of stream (pipe 50 linear feet of perennial stream, place rip rap in 20 linear feet of .perennial stream, flood 210 linear feet of perennial stream, and pipe 20 linear feet of intermittent stream) to construct the agricultural pond at the subject property. However if additional impact occurs or your development plans change, this waiver is no longer valid and a 401 Water Quality Certification will be required. Please call Ms. Cyndi Karoly or Mr. Ian McMillan at 919-733-1786 if you have any questions regarding this waiver.

Please reference the request for additional information received by the North Carolina Division of Water Quality (DWQ) in response to the permit application dated on March 16, 2006 requesting written authorization for the construction of one road crossing; and an impoundment and associated dam. Items 1-4 will be discussed below. 1. Joseph Dehart is proposing this pond so that he may provide drinking water to grazing livestock and irrigation water for a small silviculture operation. This table identifies the need for a 0.77 acres pond based on water demands. Flora/Fauna Using Water Gallons Per Day Required No. of Flora/Fauna on Property Total Amount of Water Needed Per Da Horse 12 5 60 Cow 30 10 300 Goats 3 10 30 Pine Seedlings 1 7259 7259 An additional 9% should be added to this total; 2% to account for evapotranspiration and 7% to maintain a base pool elevation. Water needs to be available such that pines and livestock can be sustained for up to 10 days without supplemental rain fall. Given all these factors, the total volume of the pond needs to be approximately 76460 gallons. A pond with a surface area of 0.77 acres and an average depth of 2.5 feet would yield the water necessary to maintain all pines and livestock on the property.

The pond as originally proposed was 1.08 acres. The size of the pond was reduced to 0.77 acres. With both ponds having the some average depth, this reduced the pond by 27009 gallons. Flooding was decreased by 365 linear feet. The dam, spillway, and driveway crossing were reconfigured during the design process minimizing the footprint of the dam and amount of rip-rap needed at the base of the spillway and at the driveway crossing; decreasing impacts by 35 linear feet. 3. and 4. There is only one home on the 20-acre parcel. There is a possibility that the applicant's brother will build a home on the property. Sewage disposal will be handled through a permitted septic system. BMPs will be utilized during any construction on the property to prevent erosion on the site. Quantity of stormwater will not increase or decrease due to this project. Should you have any further questions regarding the proposed construction at Joseph Dehart's property, please do not hesitate to contact me at 828-713-1930. Best regards, Rebekah L.

The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts.The dam of the proposed pond is beine constructed in the best topographical location for a dam. There is an existing road within the pond area so there has been past disturbance The pond was decreased in size to avoid fiirther stream impacts The hard impacts associated with the pond have been reduced to 70 linear feet through the design process The pond will have a cold water release discharge. VIII. 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. 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 Page of 8 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/ncwetlands/strmgide.html. 1. 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. The proposed mitigation-plan involves the preservation of 3,200 linear feet of streams with 25' buffers Further mitigation involves the establishment of vegetation along approximately 300 linear feet of shore around the pond. The preservation is proposed at a 10:1 ratio for stream impacts. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

Box 590 Raleigh, NC 27602-0590 Subject Property: 2654 S. Saunders Street Stream Stabilization Ut to Walnut Creek [030402, 27-34-(4), C, NSW] Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River Buffer Protection Rules (15A NCAC 2B .0233) with Additional Conditions Dear Mr. Dawson: You have our approval, in accordance with the attached conditions and those listed below, to place fill within or otherwise impact 125 linear feet of perennial stream and 1,000 square feet (ft) of Zone 1 Neuse River protected riparian buffer for the purpose of performing stream stabilization on an unnamed tributary to Walnut Creek at the subject property, as described within your application dated March 26, 2006, which was received by the N.C. Division of Water Quality (DWQ) on March 30, 2006. After reviewing your application, we have decided that the impacts are covered by General Water Quality Certification Number(s) 3495 (GC3495). The Certification(s) allows you to use Nationwide Permit(s) NW 13 when issued by the US Army Corps of Engineers (USACE). This letter shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233. In addition, you should obtain or otherwise comply with any other required federal, state or local permits before you go ahead with your project including (but not limited to) Erosion and Sediment Control, and Non-discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA Permit. This approval is for the purpose and design that you described in your application. If you change your project, you must notify us and you may be required to send us a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter and is thereby responsible for complying with all conditions. If total fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h). This approval requires you to follow the conditions listed in the attached certification and any additional conditions listed below. The Additional Conditions of the Certification are: 1. Impacts Approved The following impacts are hereby approved as long as all of the other specific and general conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are approved including incidental impacts: None Carolina 401 Oversight/Express Review Permits Unit Nf!lrallf 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 /FAX 919-733-6893 / Intemet:http://h2o. en r. state. nc. us/ncwetla nds An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper City of Raleigh - Department of Public Works Page 2 of 3 April 17, 2006 Amount Approved Units Plan Location or Reference Stream - perennial 125 linear feet PCN page 8 of 12 Buffer -Zone 1 1,000 (square ft.

Erosion & Sediment Control Practices Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. 3. No Waste, Spoil, Solids, or Fill of Any Kind No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. 4. Diffuse Flow All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at non-erosive velocities through the protected stream buffers such that it will not re-concentrate before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not possible, it may be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require additional approval from this Office. 5. Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked with orange warning fencing (or similar high visibility material) for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 2B 33 and GC 3402. 6. No Sediment & Erosion Control Measures w/n Wetlands or Waters Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project. City of Raleigh - Department of Public Works Page 3 of 3 April 17, 2006 7.

SAUNDERS STREET Introduction This narrative supplements the Pre-Construction Notification Application for the referenced project. The City of Raleigh is submitting this stream bank repair request on behalf of Mr. and Mrs. Margulies, the owners of the property at 2654 S. Saunders Street. The City of Raleigh Stormwater Drainage Policy Resolution (1998)-833 is a cost-share program that provides financial and technical assistance in alleviating severe erosion, structural flooding and /or public nuisance on fully developed private property. This policy is available to citizens within the City of Raleigh's corporate limits. Proiect Scope An unnamed tributary in the Walnut Creek Watershed runs through the referenced property. It has experienced severe erosion. A site inspection was performed by staff of the City of Raleigh Public Works Department, Stormwater Management Division. The enclosed digital photographs (Figures 1, 2 and 3) indicate the findings of the site inspection. The area described below was selected as the primary focus of the proposed stream bank stabilization: DESCRIPTION PROBLEM 125 linear feet of stream channel Severe erosion has occurred along the right side of the stream channel, causing sloughing of the channel bank. Proposed Improvements The City of Raleigh proposes to stabilize the channel by reinforcing the right (facing downstream) side slope of the channel with filter fabric and riprap for a length of approximately 125 feet. Excavation of the side slope to 2H: IV and removal of sediment in the channel bottom will be required prior to placing the filter fabric and riprap. The vertical depth of the channel section varies between approximately four feet. The USGS 7.5-Minute Quadrangle map shows a blue line (perennial) stream at the location of the OFFICES • 222 WEST HARGETT STREET • POST OFFICE BOX 590 • RALEIGH. NORTH CAROLINA 27602 RECYCLED PAPER site. Site visits by staff of the Stormwater Services Division observed water in the channel during each site visit. The drainage area of the channel at this property is approximately 100 acres. As indicated in Figures 1 and 3, the right bank of the channel is adjacent to the building and parking lot. The proposed work will be performed on this side of the channel. There are a couple trees that may need to be removed along with the removal of sediment in the channel. The proposed project will stabilize the right side of the slope of the channel from further erosion. A vicinity map and more detailed map are attached. Figure 4 shows a typical repair section.
