The proposed Neuse River basin riparian buffer (NRBRB) impacts are subject to 15A NCAC 02B .0233. Impacts associated with this project include 22,800 square feet of Zone 1 and 15,200 square feet of Zone 2 NRBRB areas. Please find attached a revised application and supplemental information requesting written concurrence from the United States Army Corps of Engineers (COE) and the North Carolina Division of Water Quality (DWQ) that the activities proposed below may precede utilizing Nationwide Permit 39. We have addressed your included written comments in the following paragraphs. 1. Buffer mitigation is required for the 150 linear foot crossing at western Virginia Water Drive. Buffer mitigation is required for all road crossings that impact 150 linear feet of riparian buffer or more. Please submit a mitigation plan detailing the amount of buffer impact at this crossing and how the impact will be mitigated. Please refer to the attached western Virginia Water Drive Plan and Profile Details. The Con Span road crossing will span 134 and 140 linear feet of valley and stream lengths, respectively. Buffer mitigation should not be required for this crossing. 2. The geotechnical report provided in your application shows that bottomless culvert structures (Con-Span) are appropriate only at Boring No. B-2, the northernmost crossing. Please submit a revised application detailing the crossing structures, i.e. bridges, or culverts for the remaining proposed crossings. • Neuse R. Buffer Rules Re-Submittal Cedar Ridge Subdivision March 1, 2007 Page 2 of 2 Please refer to the revised profile views of the Virginia Water Drive Stream Crossings. The profile views assist in showing the boring locations in relation to the elevations of the creek bed, footers, and bedrock. Boring B-3 is located at the western Virginia Water Drive crossing. Since the elevations to bedrock and the footers were ± 327 and ± 323.50-feet respectively, the 3.5- feetdifferential is conducive to a bottomless culvert. The eastern Virginia Water Drive crossing has been converted to a single 60-inch RCP with headwall. To facilitate aquatic passage, 30-inches of the RCP will be buried. Please refer to the revised profile view of the Virginia Water Drive Eastern Crossing. If you should have questions or require additional clarification please feel free to contact me at 844-7437 (office), 749-8259 (cell) or email: iay~a kellerenvironmental.com.

Isolated Waters Do any isolated waters exist on the property? ^ Yes ®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. 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. 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.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: 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 proposed Virginia Water Drive Extension crossinas were strateaically placed to connect with the subdivision to the west and the large upland area between it and Phase I. The Irina Drive Extension will provide access to the upland areas to the area north of Harris Creek. The crossings were also placed perpendicular in fairly linear stream corridors and Con-Span bottomless arched culverts (CSBAC) will be utilized on two of the geologically suitable streams to avoid stream impacts. The Irina Drive CSBAC is 80 linear feet and the 12-foot span will clearly span the entire 4-feet wide stream bed and bank. Also, it was evident during our January 16, 2006 site visit that the crossing area appeared to be a historic stream crossing for agriculture and silvaculture activities. Our perennial stream determination was conducted within and Page 5 of 10 immediately upstream of the proposed crossinq area. Please refer to Sheet 6 on the attached CD for details. The eastern Virginia Water Drive 60-inch RCP is 120 linear feet and the RCP will be buried 30-inches to facilitate aquatic passage. During our perennial stream determination, we entered the subject riparian corridor from the existing Virginia Water Drive end of pavement and walked upstream via the existing sewer line on the west side to the existing pond and sewer crossing area. It was evident during our analysis that the stream in the proposed crossinq area is slightly incised. Please refer to Sheet 7 on the previously submitted CD for details. The western Virginia Water Drive CSBAC will span 134 and 140 linear feet of valley and stream lengths, respectively. The CSBAC will also include one slight turn to avoid impacting any stream bank. This crossinq area is also being utilized for utilities (i.e. sewer, etc.) to avoid additional impacts. Similar to the aforementioned CSBAC's and evident on the Overall Site Plan, this stream crossinq is being placed in a fairly linear stream section. It will provide connectivity to the existing Virginia Water Drive and the Village of Rolesville (Phase II) Subdivision on the west side. Please refer to Sheet 9 on the previously submitted CD for details. The wide spans will be placed by using a crane and bridge footings will be placed outside of the stream banks. Since all of the proposed crossinq areas have direct road access, temporary impacts to the streams will also be avoided. This proposed Phase (II) of Cedar Ridge will also use an existing sewer line that parallels Harris Creek and the two ponds. During initial construction of Phase II, a sanitary sewer line will be installed near and parallel to the southern property line. As mentioned in the previous paragraph, this new sewer line will utilize the Virginia Water Drive CSBAC area to pain access to the existing sewer line on the west side of Harris Creek. Also evident on the Site Plan, there will be minimal grading conducted on the residential lots throughout this phase. This should maximize nutrient removal through the grassed and landscaped areas. 15.78 Acres will be permanently preserved along Harris Creek and its tributaries. This includes the large pond at the rear of lots 72-88. Moreover, areas adjacent to the stream crossings will be in the dedicated open space area. This will prevent homes from encroaching into the riparian buffer areas. Examples include areas west of Lots 103 & 118. 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. Page 6 of 10 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/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 project should not be required to provide mitigation for the proposed impacts. This is due the efforts of the developer's team to avoid jurisdictional areas to the maximum extent possible. As shown in the attached Engineering Plans the properties adiacent to the stream will not encroach into the vegetated buffers to protect open waters along Harris Creek and its tributaries. Moreover areas adjacent to the stream crossings will be in the dedicated open space area. This will prevent homes from encroaching into the riparian buffer areas. Examples include areas west of Lots 103 & 118. 15.78 Acres will be permanently preserved along Harris Creek and its tributaries. This includes the large pond at the rear of lots 72-88. 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): n/a Amount of Riparian wetland mitigation requested (acres): n/a Amount ofNon-riparian wetland mitigation requested (acres): n/a Amount of Coastal wetland mitigation requested (acres): n/a Page 7 of 10 IX.

While under construction, temporary, custom sedimentation basins will be installed outside of the wetlands and streams to protect them against sedimentation along with other appropriate sedimentation and erosion control measures in compliance with the DWQ and Wake County Sedimentation and Erosion Control requirements. Fourteen Level Spreaders will be utilized to provide diffuse flow. Utilizing fourteen level spreaders that average 55-feet and are no longer than 95-feet will maximize stormwater distribution. As seen on the Site Grading and Drainage Plan site grading will be minimal. This will maximize the penetration of surface water into the rg ound. 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. To City of Raleigh Walnut Creek Waste Water Treatment Plant. XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A 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: Page 9 of 10 The proposed Cedar Ridge Subdivision proposes using bottomless culverts on the Irina Drive and downstream Virginia Water Drive West stream crossings to avoid impacts to Waters of the US. It is unlikely that the proposed project should result in cumulative stream impacts and degrade downstream stream quality. 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). ~~T March 1, 2007 Applicant/Agent's Signature Date (Agent's signature is valid only if an authorization letter from the applicant is provided.)
