If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. No future requests are anticipated for this project. 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: Only permanent impacts include stream stabilization in two areas. Stabilization method is gabion mattress. There are three stream crossings. However, timber mats will be utilized over the stream thus no impacts are anticipated. No wetlands or open waters are located along the project corridor. Sewers crossing streams are bored underneath or aerial crossings with piers outside the banks. Page 7 of 12 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 Site Number (indicate on map) Type of Impact "Type of Wetland (e.g., forested, marsh, herbaceous, bog, etc.) Located within 100-year Floodplain ( es/no) Distance to Nearest Stream (linear feet) Area of Impact (acres) Total Wetland Impact (acres) 0 No wetlands - see attached letter 3. List the total acreage (estimated) of all existing wetlands on the property: 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, multiDly length X width, then divide by 43,560. Stream Impact Number (indicate on ma) Stream Name Type of Impact Perennial or Intermittent? Average Stream Width Before Impact Impact Length (linear feet) Area of Impact (acres) 1 (also Sheet C-07) SE Beaverdam Permanent - Gabion intermittent 12 18 .005 2 (also Sheet C-06) SE Beaverdam Permanent - Gabion perennial 15 12 .004 A (also Sheet C-02) SE Beaverdam Permanent - Rip Rap perennial 25 25 .014 B (also Sheet C-02) SE Beaverdam Permanent - Rip Rap perennial 28 28 .018 C (also Sheet C-06) SE Beaverdam Permanent - Rip Rap intermittent 22 22 .011 l'otal Stream Impact (by length and acreage) 105 .052 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 Site Number (indicate on ma) Name (if of Wat e) Type of Impact Type of Waterbody (lake, pond, estuary, sound, bay, ocean, etc.) Area of Impact (acres) Total Open Water Impact (acres) 0 Page 8 of 12 6. List the cumulative impact to all Waters of the U.S. resulting from the project: Stream Impact (acres): .052 Wetland Impact (acres): 0 Open Water Impact (acres): 0 Total Impact to Waters of the U.S. (acres) .052 Total Stream Impact (linear feet): 105 7. Isolated Waters Do any isolated waters exist on the property? ? Yes FEW 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. 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. Trenchless technology was utilized where possible on this project. Three remaining aerial crossings will have encasement and piers located outside the top of bank. The stream bed needs permanent stabilization where existing sewers will be removed or have been exposed due to erosion and where new sewer crossings occur (rip-rap). 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 9 of 12 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://l12o.enr.state,nc.us/ncwetlaiids/strmgide.hti-fl1. 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. None needed - no wetlands on site and less than 150 feet of perennial 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. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.iic,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): 0 Amount of buffer mitigation requested (square feet): 0 Amount of Riparian wetland mitigation requested (acres): 0 Amount of Non-riparian wetland mitigation requested (acres): 0 Amount of Coastal wetland mitigation requested (acres): 0 Page 10 of 12 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. N/A - no change 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. N/A XIII. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ? No 0 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/ncwetiands. If no, please provide a short narrative description: This is an established old neighborhood near downtown Raleigh. Little redevelopment should occur. There are few vacant lots along the project corridor. The sewers are not being upsized to accommodate any future growth. 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). 2-2-1619 Applicant/Agent's Signature Date (Agent's signature is valid only if an authorization letter from the applicant is provided.)

Specifically, the project study area included a fifty (50) foot wide corridor surrounding the proposed sanitary sewer line as depicted in Figures 1 through 4 dated January 2007 provided by Stearns and Wheler, PLLC. Delineations were performed in accordance with guidelines set forth in the "Corps of Engineers Wetlands Delineation Manual" published in January 1987. Initial investigation of the project corridor was performed by Emilio Ancaya and Amy Wazenegger, PE, and final wetland delineation was performed by Emilio Ancaya and T. Eric Black. Initial field investigations were performed on February 15, 2007, and three (3) areas, as shown on the attached maps, were identified for more thorough investigation due to the presence of some wetland indicator plant species. Upon return to these areas on July 2, 2007, we have concluded that there are no jurisdictional wetlands present within the boundary of the project corridor defined above. Therefore, a jurisdictional determination meeting with a representative of the US Army Corps of Engineers (USACE) is unnecessary. Thank you for the opportunity to assist you with this project. If you have any questions, or require further information, please contact me at (919) 342-7132. Sincerely, WAZ Engineering, PC Amy J.
