Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The existing culvert consists of one 65 linear ft. concrete pipe, 5 ft. diameter, groove end entrance, pipe projecting from fill, and one 65 linear ft. concrete pipe, horizontal ellipse (4.9 ft. (W) x 3 ft. (H)), square edge with headwall. The general landuse surrounding the area is Residential. 10. Describe the overall project in detail, including the type of equipment to be used: Construction activity will include the removal and replacement of approximately 100 linear feet of roadway and embankments, foundation excavation for and construction of three 71 ft. long, 4 ft. high by 8 ft. wide reinforced concrete box culverts, with the middle culvert 6 inches lower than the two outer culverts to maintain a low flow channel, minor grading at the culvert ends to tie existing ground to proposed culvert inlets, and installation of the minimum length of rip rap required for stabilization for inlet protection and step pools for outlet protection. It is anticipated that earth moving equipment such as hydraulic excavators and/or bulldozers will be used. Project also includes construction of a temporary access road around the site. The access road will be in use while existing culverts are removed and box culverts are constructed. The access road is required to construct the work and the road is a dead end road. Access must be maintained at all times for safety. 11. Explain the purpose of the proposed work: The purpose of the proposed work is to reduce the frequency of flooding to houses upstream of Ravenwood Drive and on the roadway by providing additional flow area so that backwater during large events will be reduced. The middle culvert will be constructed 6 inches lower than the two outer culverts to maintain a low flow channel. Rip rap upstream and step pools downstream of the culverts will be included to maintain stability of the stream and prevent erosion. Page 7 of 13 P-1 IV.

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. The applicant must also provide justification for these impacts in Section VII below. All proposed impacts, permanent and temporary, must be listed herein, and must be clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) must 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: The project will replace the existing culverts with three concrete box culverts. In addition, channel improvements will occur immediately upstream and downstream of the culvert to minimize aegradation / degradation of the streambanks. The channel improvements will include the minimum required rip rap for inlet protection and step pools immediately downstream of the culverts for outlet protection. A temporary access road will be constructed around the site. The access road will be in use while existing culverts are removed and box culverts are constructed. The Page 8 of 13 access road is required to construct the work and the road is a dead end road. Access must be maintained at all times for safety. 2.

(indicate on map) r (li near feet) Name Before Impact (pleasespecify) I Restoration / 80 Simmons 22 ft. Perennial Stabilization Branch * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: culverts and associated rip-rap, dams (separately list impacts due to both structure and flooding), relocation (include linear feet before and after, and net loss/gain), stabilization activities (cement wall, rip-rap, crib wall, 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. ** Stream names can be found on USGS topographic maps. If a stream has no name, list as UT (unnamed tributary) to the nearest downstream named stream into which it flows. USGS maps are available through the USGS at 1-800-358-9616, or online at www.us9s.,10v. Several internet sites also allow direct download and printing of USGS maps (e.g., www.topozone.com, www.mapquest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 80' 4. Individually list all open water impacts (including lakes, ponds, estuaries, sounds, Atlantic Ocean and any other water of the U.S.) below: Page 9 of 13 Open Water Impact Site Number (indicate on ma) Type of Impact* Area of Impact (acres) (if Name applicable) ody Type of Waterbody (lake, pond, estuary' sound, bay, ocean, etc.) n/a n/a n/a n/a n/a * List each impact separately and identify temporary impacts. Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. 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. 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 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. The culvert replacement is reauired to minimize floodint?. The replacement has been desicned to disturb the minimal length of stream required for the culvert replacement. Proposed stream restoration/stabilization techniques and outlet protection will protect the stream from future erosion. The inlet and outlet protection measures have been minimized to include only the measures needed to prevent erosion and stabilize the stream bank. 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 page 10 of' 13 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 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 htti)://h2o.enr.state.nc.us/ncwetlands/strmeide.htm1. I. 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 stream impact by the culvert replacement is not being considered for mitigation since an existing culvert is present. Stream impacts associated with stream restoration / stabilization techniques total 80 linear feet and should be allowable without mitigation. 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. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wM/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): n/a Amount of buffer mitigation requested (square feet): n/a Amount of Riparian wetland mitigation requested (acres): n/a Amount of Non-riparian wetland mitigation requested (acres): n/a Page 1I of 13 Amount of Coastal wetland mitigation requested (acres): n/a IX.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The existing culvert consists of one 65 linear ft. concrete Page 6 of 12 pipe, 5 ft. diameter, groove end entrance, pipe projecting from fill, and one 65 linear ft. concrete pipe, horizontal ellipse (4.9 ft. (W) x 3 ft. MA square edge with headwall. The general landuse surrounding the area is Residential. 10. Describe the overall project in detail, including the type of equipment to be used: Construction activity will include the removal and replacement of approximately 100 linear feet of roadway and embankments, foundation excavation for and construction of three 71 ft. long, 4 ft. high by 8 ft. wide reinforced concrete box culverts, with the middle culvert 6 inches lower than the two outer culverts to maintain a low flow channel, minor grading at the culvert ends to tie existing ground to proposed culvert inlets, and installation of the minimum length of rip rap required for stabilization for inlet protection and step pools for outlet protection. It is anticipated that earth moving equipment such as hydraulic excavators and/or bulldozers will be used. 11. Explain the purpose of the proposed work: The purpose of the prof osed work is to reduce the frequency of flooding to houses upstream of Ravenwood Drive and on the roadway by providing additional flow area so that backwater during large events will be reduced. The middle culvert will be constructed 6 inches lower than the two outer culverts to maintain a low flow channel. Rip rap upstream and step pools downstream of the culverts will be included to maintain stability of the stream and prevent erosion. IV.

Impacts include, but are not limited to: fill, excavation, dredging, flooding, drainage, bulkheads, etc. 5. 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. 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 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. The culvert replacement is required to minimize floodint?. The replacement has been desiizned to disturb the minimal length of stream required for the culvert replacement. Proposed stream restoration/stabilization techniques and outlet protection will protect the stream from future erosion. The inlet and outlet protection measures have been minimized to include only the measures needed to prevent erosion and stabilize the stream bank. Page 9 of 12 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 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.nc.us/ncwetiands/strmgide.htm]. 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 stream impact by the culvert replacement is not being considered for mitigation since an existing culvert is present. Stream impacts associated with stream restoration / stabilization techniques total 80 linear feet and should be allowable without mitigation. 1 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. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCWRP is proposed, please check the appropriate box on page three and provide the following information: Amount of stream mitigation requested (linear feet): n/a Amount of buffer mitigation requested (square feet): n/a Page 10 of 12 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) Does the project involve an expenditure of public (federal/state) funds or the use of public (federal/state) land? Yes ? No 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 ? 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 Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ? If you answered "yes", provide the following information: 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.

January 20, 2006 Mr. Todd Tugwell United States Army Corps of Engineers 6508 Falls of the Neuse Road, Suite 120 Raleigh, North Carolina 27615 Reference: City of Raleigh Ravenwood Drive Culvert Replacement Dewberry Project No. 73116900 0 `-1 4.J JAN, 2 3 ZOU6 R Wq 17Y "n4' ?R BRANCH Dear Mr. Tugwell: On behalf of the City of Raleigh, Dewberry and Davis, Inc. (Dewberry) would like to provide response to the comments made in the letter (Action ID No. 200420766) dated October 20, 2005 for the above referenced project. The letter mentions that North Carolina Wildlife Resources Commission (NCWRC) provided comments by letter dated September 30, 2005, and stated conditions to be incorporated into the permit to reduce impacts to fish and wildlife resources. The comments made by NCWRC are italicized and the responses by Dewberry are provided after each comment. It is unclear whether the forebay would be constructed in an area that is already impounded or whether free flowing stream channel would be impounded or excavated to create the forebay. We prefer the forebay to be constructed in areas of the lake that are currently impounded. If the applicant proposes to impound or excavate free flowing stream channel to create the forebay this will remove the natural functionality of the stream and we feel that mitigation for impact to stream channels should be performed according to the Stream Mitigation Guidelines (April 2003). Dewberry Response: The forebay proposed in the White Oak Lake Project design is located within the original lake boundary as per the 1956 plat map (please see Figure 1). As can be seen in the Figure the northern lake boundary has changed over time due to sediment deposition. The proposed forebay will be constructed by removing the accumulated sediments within the lake. No changes regarding the location of forebay are being proposed. Further, under this contention no `stream' impacts will occur. Therefore, no mitigation is being proposed. 2. We recommend that all remaining wetlands and streams on the site should be protected from additional impacts by placing them in a permanent conservation easement to prohibit filing, draining, flooding, and excavation. Dewberry Response: All remaining wetlands on the site are within the privately owned properties. Dewberry & Davis, Inc. Mr. Todd Tugwell January 20, 2006 Page 3 The lake property is recorded as a "recreational" easement on the plat map with access and use rights connected to each lot in the subdivision. Any changes in the proposed use could only occur with the consent of 300 or so homeowners and rezoning by the City of Raleigh. Therefore, the City contends that an additional permanent conservation easement should not be needed. Further, it should be noted that the streams and wetlands already have significant protection in the form of Neuse Buffers and the City of Raleigh tree protection and floodplain ordinances. Should the water level need to be lowered to perform the dam construction and dredging, we request that the lake be lowered and the work completed, if possible, between 15 October and 15 March to minimize fish stress and chance of a fish kill. Dewberry Response: The bidding and construction schedules for this project are not currently known. If possible, the City will coordinate dam construction within the requested time period. 4. Should the lake remain at normal pool during the dredging, we request that dredging not occur between 15 March and 15 July. Fish spawn in spring and young fish occupy near shore habitats in early summer. Prohibiting dredging during this time period will minimize impacts to the fish population in the lake. Dewberry Response: It is anticipated that dredging will be done `in-the-dry' or during lowered water conditions that coincide with dam reconstruction. However, if wet dredging is proposed by the contractor the City will endeavor to restrict dredging during this time period if possible. 5. All sediment removed is deposited in upland areas or is disposed of at an approved facility. Dewberry Response: Some of the sediment may be used in the construction within the lake to establish shallow shelves and/or to provide backfill between the existing and proposed dam locations. Appropriate measures will be taken to avoid placing the sediments in the streams or wetlands on site except as noted above. The City will require the contractor to dispose of all sediments removed from the site at a State approved facility. Specialized efforts and techniques are implemented to reduce sediment runofffrom construction activities. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. Dewberry Response: Erosion and sediment from construction activities will be controlled by approved methods as described in the Wake County Erosion Control Permit Manual. An Erosion and Sediment Control Permit will be obtained for this project by the City prior to construction. 7. Concrete is toxic to aquatic life and should not be allowed to come in contact with surface waters until cured. Dewberry Response: Concrete structures will be pre-cast and fully cured or cast-in-place `in-the- dry' and fully cured prior to allowing contact with open water. Dewberry Mr. Todd Tugwell January 20, 2006 Page 3 8. Should free flowing stream channels be impacted by construction of the sediment pool, a mitigation plan should be submitted and approved before impacts occur. Dewberry Response: As noted in response to Comment 1 the forebay construction is proposed to be within the original boundary of the lake and therefore the City contends that no stream impacts will occur. Hence, no mitigation is currently proposed. We look forward to your review of our responses for this important project for the City of Raleigh.
