Name of project: Beechwood Hills Lake Western Cove Dredging & Forebay T.I.P. Project Number or State Project Number (NCDOT Only): N/A 3. Property Identification Number (Tax PIN): None 4. Location County: Franklin Nearest Town: Franklinton Subdivision name (include phase/lot number): Beechwood Hills Directions to site (include road numbers/names, landmarks, etc.): The subdivision is bordered to the east by Billys Creek with Autumn Dr being roughly the border to the west. From Raleigh take Capital Blvd./ US-1 N. Continue to follow US-1 N. to Highway 56 East at Franklinton. Turn right on to Hwy 56 East toward Louisburg then in downtown Franklinton (about 0.4 miles) turn left on Main Street (HWY 1-A North) Follow Main St north thru town (0.5 miles) and turn right on Pearce St (there is an old white block building where you turn and you will immediately cross a railroad track) then take the next left on to Winston street (it is only 100' from the RR Track to Winston St). Take Winston St. about 0.5 miles then turn right on Beechwood rd. and go about 0.5 miles then bear left onto Autumn Dr after you pass thru a security -gate. Take Autumn drive to about 0.1 mile from the end (about 0.3 miles). The existing access path and cove will be to your right just before you cross a tributary stream. Site coordinates (For linear projects, such as a road or utility line, attach a sheet that separately lists the coordinates for each crossing of a distinct waterbody.) Decimal Degrees (6 digits minimum): 36.1210°N. 78.4422°W 6. Property size (acres): 270 acres (entire subdivision) 7. Name of nearest receiving body of water: Billys Creek (WS-IV:NSW): 28-20 Page 2 of 9 8. River Basin: Tar-Pamlico (Note - this must be one of North Carolina's seventeen designated major river basins. The River Basin map is available at http://h2o.enr.state.nc.us/admin/maps/.) 9. Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site has been a large lot single family subdivision since 1986 ; prior to development, the site was forest land. Land use in the vicinity of this site is a mix of residential development and forestland. Describe the overall project in detail, including the type of equipment to be used: Perform Maintenance dredging to restore lake bottom to original contours in The west cove of the lake. As the attached "sandbar" photo shows (the lake has been lowered 6' to allow the sediment to dry and be evaluated for contractors to give estimates for removal). The excavated area will be roughly 50' wide by 110' long. There is an existing path that has been historically used to access the lake for maintenance dredging (see photos). However, the sediment remaining is beyond the reach of the equipment (excavators) so they will have to work on mats on the lake bottom and possibly double handle material. The dredging will result in no permanent impacts and no loss of waters of the US. The two issues here are from a 404/401 standpoint the desire to install a gabion wall below water level so that the area can be maintained in the future without entering the lake as has been done on the south end. New lakes are now designed with this forebay installed from the start. The gabion wall will be 40' long and about 10' wide ( See attached sketches). While this is fill (thus necessitating the 404) there is no loss of waters of the US since the gabion top will below the normal poll elevation of the lake. The buffer approval issue is that the contractor believes they will need to add gravel to the path where none currently exists for the trucks hauling the sediment to a high ground disposal site to climb the hill (see maps for disposal site location). The buffer rules allow for temporary roads within the buffer with no approval required. While this is fine and would work (the contractor would just remove the gravel after the work is done), knowing that they will need to get back in at some time in the future the removal of the gravel does not make sense economically nor environmentally. Based on emails with Amy Chapman, she believed this could be approved without mitigation under the buffer rules (see attached email correspondence) 10. Explain the purpose of the proposed work: The purpose of the proposed work is to provide maintain useable open water for the homeowners in an existing subdivision and lake which existed prior to the adoption of the Tar-Pam Riparian Buffer rules. IV. Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. Provide photocopies of previously issued permits, Page 3 of 9 certifications or other useful information. Describe previously approved wetland, stream and buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project, list and describe permits issued for prior segments of the same T.I.P. project, along with construction schedules.. This project has no previously issued 401 or 404 permits since it was constructed at a time when the impacts would have been below notification thresholds (i.e. 1986) V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. No future permit requests are anticipated for this subdivision VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Fill will include a gabion wall to form a forebav below water level, it will be roughly 40' long and 10' wide at the base Additionally 0.12 acres of lake bottom will be dredged to original contours with sediment removed to a high round disposal site. 2. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding. Wetland Impact Type of Wetland Located within Distance to Area of Site Number Type of Impact (e.g., forested, marsh, 100-year Nearest Impact (indicate on map) herbaceous, bog, etc.) Floodplain Stream (acres) (yes/no) (linear feet) N/A None N/A N/A N/A 0 Total Wetland Impact (acres) 0 Page 4 of 9 3. List the total acreage (estimated) of all existing wetlands on the property: The project area contains no wetlands only waters of the state (a lake) 4. Individually list all intermittent and perennial stream impacts. Be sure to identify temporary impacts. Stream impacts include, but are not limited to placement of fill or culverts, dam construction, flooding, relocation, stabilization activities (e.g., cement walls, rip-rap, crib walls, gabions, etc.), excavation, ditching/straightening, etc. If stream relocation is proposed, plans and profiles showing the linear footprint for both the original and relocated streams must be included. To calculate acreage, multiply length X width, then divide by 43,560. Stream Impact Perennial or Average Impact Area of Number Stream Name Type of Impact Intermittent? Stream Width Length Impact (indicate on ma) Before Impact (linear feet (acres) N/A N/A None N/A N/A 0 0 Total Stream Impact (by length and acreage) 0 0 5. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.). Open water impacts include, but are not limited to fill, excavation, dredging, flooding, drainage, bulkheads, etc. Open Water Impact Name Wate Type of Waterbody Area of Site Number e) (if applicable) Type of Impact (lake, Pand estuary, sound, bay, Impact (indicate on ma) ocean, etc.) (acres) 1 Beechwood Hills Lake Fill Lake 0.01 Excavation 0.12 Total Open Water Impact (acres) permanent 0.01 6.

Isolated Waters Do any isolated waters exist on the property? Yes X No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. N/A 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Page 5 of 9 Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): N/A Current land use in the vicinity of the pond: N/A Size of watershed draining to pond: N/A Expected pond surface area: N/A VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. 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.. No new forest vegetation will be removed for the access oath, the proposed path area is within an area that was cleared for that purpose prior to the buffer rules and has been maintained since clearing in 1986. At substantial cost the applicant is constructing a forebay so future maintenance can be done from high ground without entering the lake bed with equipment. 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 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/ncwctlands/stn-ngide.html. Page 6 of 9 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. Because impacts are proposed to iurisdictional areas are below DEQ mitigation thresholds and result in no loss of Waters of the US no open water mitigation is proposed. Additionally, the riparian buffer impacts proposed are considered "allowable" therefore no riparian buffer mitigation is proposed please see section X.3 and the attached email from Amy Chapman for details 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. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): N/A Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): N/A Amount of Non-riparian wetland mitigation requested (acres): N/A Amount of Coastal wetland mitigation requested (acres): N/A IX. Environmental Documentation (required by DWQ) 1. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ? No 2. If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ? No ? 3. If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Page 7 of 9 Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. 1. Will the project impact protected riparian buffers identified within 15A NCAC 213 .0233 (Meuse), 15A NCAC 213 .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ? 2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. INDIVIDUAL LOT PIER Access Path Zone* Impact Multiplier Required (square feet) Mitigation 1 450 3 0 2 300 1.5 0 Total 750 0 * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 213 .0242 or.0244, or.0260. Riparian buffer impacts proposed are to activities defined as trails and are considered an "allowable" use within the NCAC 02B .0259(6): Table of uses therefore mitigation is not required In fact temporary access paths could be constructed without notification, but as described above would not make sense in this situation. XI. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. The subdivision is a large lot single family subdivision well below 24% IMPERVIOUS (LOTS ARE FROM 2.5 ACRES TO 18 ACRES IN SIZE) AND WAS CONSTRUCTED PRIOR TO THE Tar Pam buffer rules or the 401 stormwater requirements. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. The existing homes are connected to an existing countv approved septic systems Page 8 of 9 XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (I 5A NCAC 2H .0500) or any Buffer Rules? Yes ? No Is this. an after-the-fact permit application? Yes ? . No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ? No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: I have reviewed the "DRAFT Internal Policy Cumulative impacts and the 401 Water Quality Certification and Isolated Wetland Programs" document prepared by the NC Division of Water Quality on October 3 2002, version 1.6. The proposed project will not result in new lots so no additional impacts would be anticipated XV. Other Circumstances (Optional): 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).

Well the good news for the buffer portion of the project for the path on the west cove, is that it can be covered under a buffer authorization requiring no mitigation under the use in the table of uses for greenway/hiking trails. And since they'll need to have a 404/401 for this section of the project, the buffer impacts can just be roped in with that. I talked to Ian about the 401/404 for the gabion wall in the western cove they're proposing and we can't say we'd have a problem with it. Of course we'll have to review it, but it shouldn't be an obstacle. The south end portion of the project sounds like no written concurrence will be needed from DWQ. Let me know if we still need to meet. Thanks. -Amy Kevin Martin wrote: Amy, attached are some photos of one of the projects we will be discussing Thursday. The Corps has agreed they can cover the maintenance dredging under one or more nationwide permits (29, 18 and/or 33 or 40). This lake was built in 1986 and for years they have been removing accumulated sediment every couple of years using existing access paths that are not graveled, and by sitting equipment on the bank and reaching as far as they can. This is and will continue to be effective at the south end of the lake where gabions were installed to slowdown the water and allow silt to accumulate behind them. The area is accessible from both sides and within the reach of the equipment without double handling the material or entering the bed of the lake. The Corps position on that work is that it does not require a 404 permit, and since the path at the south end is graveled and the gabions were in place for many years there is not a buffer issue since it is an existing use prior to 1/1/00 The west cove of the lake is a bit different. as the "sandbar" photo shows (the lake has been lowered 6' to allow the sediment to dry and be evaluated for contractors to give estimates for removal). The excavated area will be roughly 50' wide by 110' long. There is an existing path here as well (see photos), but the sediment remaining is beyond the reach of the equipment so they will have to work on mats on the lake bottom and possibly double handle material. The two issues here are from a 404/401 standpoint the desire to install a gabion wall below water level so that the area can be maintained in the future without entering the lake much as has been done on the south end. New lakes are now designed with this forebay installed from the start. The gabion wall will be 40' long and about 10' wide ( I will send hand sketches by another email). I do not see this as an issue either, while it is fill (thus necessitating the 404) there is no loss of waters of the US. The issue is that the contractor believes they will need to add gravel to the path where none currently exists for the trucks hauling the sediment to a high ground disposal site to climb the hill. The buffer rules allow for temporary roads within the buffer with no approval required. While this is fine and would work they would just remove the gravel after the work is done. However knowing that they will need to get back in at some time in the future the removal does not make sense economically nor environmentally. The HOA does not have $ to pay a lot of mitigation costs so I was trying to figure a way to handle this without mitigation, the sediment removal alone is costing $34,000.00.
