We also request written concurrence from the North Carolina Division of Water Quality (DWQ) that the project complies .with GC 3402 and the Neuse Buffer Rules for proposed impacts. APre-construction Notification Application (PCN) is attached, as well as an agent authorization form. , The proposed residential subdivision is located on the north side of High House Road approximately 0.5 mile west of the intersection of Maynard St. and High House Road (SR 1616) in Cary, NC, Please see the attached USGS site vicinity map. Soil & Environmental Consultants, PA delineated the jurisdictional features on-site in August 2003. On September 1 S, 2003, a buffer determination was made by Deborah Edwards of the NC DWQ (NBRRO 03-272). The USAGE (Ms. Andrea Wade) made a ' jurisdictional determination on the site (Action ID # 200321392), which the applicant has reflected on the attached impact map. - The proposed single-family residential subdivision plan was developed to create the least amount of impacts possible. One road crossing of a perennial buffered stream is required in order to fully connect the site.

Level spreaders will be used to insure diffuse flow into the buffers. Worksheets are attached, that correspond to each proposed level spreader. Perpendicular road crossings impacting less than 1/3 acre of riparian buffer are considered an "allowable" activity under the Neuse Buffer Rules, therefore no buffer mitigation is proposed. Because the resulting stream impacts are less than 1501inear feet, stream mitigation is not required by the NC-DWQ. If the USACE requires stream mitigation, payment to the NC EEP is proposed to satisfy these requirements. Please call or email at SClark ,SandEC.com me if you have any questions.

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.): NA Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): NA Size of watershed draining to pond: NA Expected pond surface area: NA VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe 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 applicant requested that S&EC delineate wetlands and stream features on-site to aid planning and avoid impacting iurisdictional features. The applicant has reduced potential impacts to one perpendicular channel crossing. The road crossing is needed to connect the northern section of the property to the southern portion. 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 Page 5 of 8 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/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. Perpendicular road crossings impacting less than 1/3 acre of riparian buffer is an "allowable" activity under the Neuse Buffer Rules, therefore no buffer mitigation is proposed. Because the resulting,, stream impacts are less than 150 linear feet, stream mitigation is not required by the NC DWQ. If the USACE requires stream miti ation. payment to the NC EEP is proposed to satis ,these requirements. 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/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): NA Amount of buffer mitigation requested (square feet): NA Amount of Riparian wetland mitigation requested (acres): NA Amount ofNon-riparian wetland mitigation requested (acres): NA Amount of Coastal wetland mitigation requested (acres): NA 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 ^ Page 6 of 8 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 (Meuse), 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. Zone* Impact s ware feet Multiplier Required Miti ation 1 8811 3 NA 2 S 184 1.S NA Total 13,995 NA * Zone 1 extends out 30 feet perpendicular from near bank of channel; Gone Z extends an additiona120 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, Conservation Easement, Riparian Buffer Restoration /Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 1 SA NCAC 2B .0242 or .0260. Proposed buffer impacts oniv result from a sin>;le road .crossing and total less than 1/3 acre (allowable activitx) Therefore no buffer mitigation is proposed. XI. Stormwater (required by DWQ) Describe impervious acreage (both 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. Total impervious acreaz?e on-site amounts to 24,86% of total acreage. Because this is under 30% no formal stormwater management plan is being submitted however level spreaders are Page 7 of 8 being used to insure diffuse flow into the buffers Please find the attached level spreader worksheets. 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~roject will tie into an existing sewer line on the property running parallel on the north side of the stream with th~roposed road crossing_ 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 anafter-the-fact permit application? Yes ^ No XIV. 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).
