Re: Park at Langston Wake County DWQ # 020831 The Division of Water Quality has reviewed your response, received June 26, 2002, to our request for additional information regarding your application for a 401 Certification and Neuse Buffer Rules Approval, received May 24, 2002, for the subject project. In previous correspondence dated June 4, 2002, this Office requested that you provide plans and calculations to show that diffuse flow of stormwater would be provided in the Neuse Riparian Buffers in compliance with 15A NCAC 213 .0233 (5). Only one plan page was provided that indicated some kind of level spreader for one of the five listed stormwater outlets. No calculations were provided to show that this level spreader is adequately sized, and no topographic information was provided to show that the slopes were adequate to accept the flow. No calculations or (readable) plans were provided for the other outlets. This information was needed by DWQ in order for us to decide whether this project is approvable. Since the requested information was not provided, we are hereby returning the subject application. As such, this application is withdrawn. Should you decide to reapply you must provide seven copies of an application and supporting documentation as well as the appropriate fee.

We also request written concurrence from the NC Division of Water Quality (NC-DWQ) that the project complies with the 401-Water Quality Certification associated with Nationwide Pen-nit 39, and that it complies with the Neuse River Riparian Buffer rules. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. S&EC performed a Neuse River Buffer evaluation for the site in fall 2000, and a detailed wetland delineation in April 2002, which was submitted to the USACE for approval on May 20th, 2002. Data forms for the delineation are attached. NC-DWQ confinned S&EC's Neuse River Buffer evaluation (NBRRO 01-199-see attached). The proposed project, which consists of a residential subdivision, is located east of West Lake Rd. (SRI 387), west of Bells Lake Rd. (SR 1386), approximately one mile south of Ten-Ten Rd. (SR 1010) near Cary, Wake County, NC. Please refer to the USGS site map. The property comprises approximately 32 acres, and is in the Neuse River Basin. Approximately 0.003 acres (1,278 ft. 2) of jurisdictional wetlands and 85 linear ft. of stream channel will be impacted for a roadway crossing (Impact 1-see impact maps) under Nationwide Permit 39 (totaling 0.03 acres/85 linear ft.). Approximately 9,983 ft.2 (zone 1: 6,291 ft. 2, zone 2: 3,692 ft.2) of Neuse River Buffer will be impacted by the proposed roadway crossings (Impact 1). Approximately 0.011 acres (495 11.) of jurisdictional wetlands and 20 linear ft. of stream channel will be temporarily impacted under NWP 12 (Impact 2-see impact maps). Total proposed impacts are 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft. temporary). The Town of Cary originally required two roadway crossings over the channel where proposed impacts will occur in order to preserve connectivity within the site-despite our client's wishes-who understood that the two crossings conflicted with avoiding and minimizing unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker (our client), S&EC, and a project engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to discuss the crossing requirement. After this meeting, the project's land planner and engineer were able to convince Cary to drop one of the required roadway crossings, leaving the one proposed in this application, which is necessary to access high ground in the northeastern portion of the property. Additionally, DOT has relaxed the minimum turn radius requirement for the extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer impacts. It is important to note that the road shown entering the site on the northern property line is not yet constructed, and is a reserved road right-of-way-not a dedicated right-of-way. Thus, the road right-of-way is still owned by the adjacent site's developer. Additionally, there is a gas line easement parallel to the northern property line immediately adjacent to the property. The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification. The proposed roadway crossing is necessary in order to access high ground in the northeastern portion of the property. This road is an extension of a stubbed road on the western property line. Both the roadway and sewer line crossing, as evinced by the site plan, have been designed to cross wetland areas and the stream channel perpendicularly. A large, contiguous bottotnland hardwood forest wetland in the middle of the property has been completely avoided, as have all other wetlands/waters of the U.S. onsite. NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts below 1 acre and 150 linear feet of significant channel per project. Because the proposed cumulative impacts resulting from the project total 0.0411 acres (0.011 acres temporary)/105 linear ft. (20 ft. temporary), project impacts are below the aforementioned thresholds, and S&EC believes that neither wetland nor stream channel mitigation should be required Additionally, NC-DWQ's current policy does not require mitigation for buffer impacts if they do not exceed 1 /3 acre per buffered channel tributary. Because the proposed buffer impacts resulting from the project do not exceed the aforementioned threshold (9,983 ft.2 or 0.229 acres), buffer mitigation should not be required. Because the proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than co sa ?

If written approval is required or specifically requested for a 401 Certification, then a non-refundable application fee is required. In brief, if project impacts include less than one acre of cumulative wetland/water impacts and less than 150 feet cumulative impacts to streams, then a fee of $200 is required. If either of these thresholds is exceeded, then a fee of $475 is required. A check made out to the North Carolina Division of Water Quality, with the specific name of the project or applicant identified, should be stapled to the front of the application package. For more information, see the DWQ website at http://h2o.ehnr.state.nc.us/ncwetlands/fees.htmi. The fee must be attached with the application unless the applicant is a federal agency in which case the check may be issued from a separate office. In such cases, the project must be identifiable on the U.S. Treasury check so that it can be credited to the appropriate project. If written approval is sought solely for Buffer Rules, the application fee does not apply, and the applicant should clearly state (in a cover letter) that only Buffer Rule approval is sought in writing. Wetlands or waters of the U.S. may not be impacted prior to issuance or waiver of a Section 401 Water Quality Certification. Upon receipt of a complete application for a 401 Certification, the Division of Water Quality has 60 days to prepare a written response to the applicant. This may include a 401 Certification, an on-hold letter pending receipt of additional requested information, or denial.

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 storinwater requirement, etc.): 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 inforination 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 Town of Cary originally required two roadway crossings over the channel where proposed impacts will occur in order to preserve connectivity within the site-despite our client's wishes-who understood that the two crossings conflicted with avoiding and minimizing unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker (our client), S&EC, and aproject engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to discuss the crossing requirement. After this meeting the project's land planner and en iineer were able to convince Cary to drop one of the required roadway crossings, leaving the one proposed in this application which is necessary to access high ground in the northeastern portion of the property. Additionally DOT has relaxed the minimum turn radius requirement for the extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer impacts. The proposed road crossing (Impact 1) has been designed to cross the stream channel at a perpendicular angle to minimize impacts. The proposed sewer line crossing (Impact 2) also has been designed to cross the stream, wetland area, and buffer perpendicularly to minimize impacts. VIII. Mitigation DWQ - In accordance with 15A NCAC 21-1 .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 7 of 12 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 Pennits, 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 detennining 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.htmi. 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 USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification. The proposed roadway crossing is necessary in order to access high gEound in the northeastern portion of the property. This road is an extension of a stubbed road on the western property line, and crosses the stream perpendicularly, impacting as little channel as possible. The sewer line crossing is necessary to provide all portions of the property with sanitary sewer access. A large, contiguous bottomland hardwood forest wetland in the middle of the property has been completely avoided, as have all other wetlands/waters of the U.S. onsite. NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts below 1 acre and 150 linear feet of significant channel. Because the proposed cumulative impacts resulting from the project total 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft. temporary-i.e. less than 1/3 acre and 150 ft.) wetland or stream channel mitigation should not be required Page 8 of 12 Additionally NC-DWQ's current policy does not require mitigation for buffer impacts if they do not exceed 1/3 acre per buffered channel tributary. Because the proposed buffer impacts resulting from the project do not exceed the aforementioned threshold (9,983 ft.2 or 0.229 acres) buffer mitigation should not be required. Because the proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than 40 ft. wide, it is considered an "exempt" activity by the Neuse River Basin Riparian Buffer Rules, and should not require riparian buffer mitigation. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option. 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 Amount of Riparian wetland mitigation requested (acres): N/A Amount of Non-riparian wetland mitigation requested (acres):- Amount of Coastal wetland mitigation requested (acres): N/A IX. Environmental Documentation (DWQ Only) Does the project involve an expenditure of public funds or the use of public (federal/state/local) 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 (DWQ Only) 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 N/A Page 9 of 12 map, whether or not impacts arc 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 Neuse )? 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 (square feet) Multiplier Required Mitigation 1 6,291 3.0 N/A 2 3,692 1.5 N/A Total 9,983 N/A Zone I extends out 30 tect perpcndficular trom near bank of channel; /.one L 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, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0260. XI. Stormwater (DWQ Only) 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. Impervious acreage on the site is not expected to exceed 30%, therefore, a stormwater_plan should not be required. However, the site stormwater plan is enclosed with this application. XII. Sewage Disposal (DWQ Only) 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. Connection to an existing sanitary sewer easement Page 10 of 12 XIII. Violations (DWQ Only) Is this site in violation of DWQ Wetland Rules (I 5A NCAC 21-I .0500) or any Buffer Rules? Yes ? No Is this an after-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). 0 Applica Agen ' "'ignatt# v Date (Agents nature is vali4//only if an authorization letter from the applicant is provided.)

Proposed Tributary Dr. does not extend past our project. There is a reserved right-of-way and not a dedicated right-of-way north of the termination of Tributary Dr. on our site. Please be advised that a reserved right-of-way means that the Ownership of this particular right-of way is still held by the original developer. ,Also, there is a 50 ft. Colonial Pipe line right-of-way carrying three major gas transmission lines within the reserved right-of-way. The extension of Alphawood Dr. will be the only means of accessing the area north east of the proposed creek crossing.

The features represented on the Wake County Soils and the USGS Lake Wheeler and Apex Quad maps were evaluated to determine their subjectivity to the Neuse Buffer Rule on July 2, 2001. It was determined that there a total of five features depicted on the property on the two maps. Three features are subject to riparian buffer protection and are labeled as A, B, and C on the plat map received August 10, 2001. This letter only addresses the applicability of the Neuse River Basin: Nutrient Sensitive Waters Management Strategy; Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A:02B.0233 (NCAC 0233).

They are required by Wake Co. to put in Crossing "A" and by the Town of Cary to put in Crossing "B". The Town has written a letter referencing their new (?) connectivity ordinance. They have redesigned from the original alignments to the proposed alignments per S&EC's recommendations. The proposed alignments have less stream impact because they cross at straight sections of the stream and not meandering sections. Jim with S&EC said the stream being crossed is an intermittent stream. The stream is on the soil survey but not USGS. Mitchell has confirmed buffers but no perennial calls. Total impacts for both crossings will be kept below 150 feet. They told me that they're looking like 50 feet and 60 feet, but couldn't make any promises. Please review the attached information and let me know if you have any immediate objections. They'll be sending in a PCN most likely this week.

Jim -----Original Message----- From: Bob Zarzecki [mailto:bob.zarzecki@ncmail.net] Sent: Monday, January 28, 2002 5:01 PM To: jim_cooper@sandec.com; info@sandec.com Subject: Park @ Langston SID Jim, John's first reaction was to avoid the larger crossing (the one you did not know the name of) and cul-de-sac both ends. I told him that this crossing was required by both the County and Cary. I would recommend sending the PCN in as soon as possible to get the review process started. We may want to get all parties involved to meet, but go ahead and send it in so we can get started. - Bob fol v ?Z?? O?O? W A T ?RPG r Michael F. Easley, Governor William G.

After reviewing your application, we have determined that this fill is covered by General Water Quality Certification Numbers 3374 and 3362, which can be downloaded from our web site at http://h2o.enr.state.nc.us/ncwetlands . This Certification allows you to use Nationwide Permit Numbers 12 and 39 when issued by the U.S. Army Corps of Engineers. This approval is also valid for the Neuse River Buffer Rules (15A NCAC 2B .0233). In addition, you should get any other federal, state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 permit expires unless otherwise specified in the General Certification. This approval is only valid for the purpose and design that you described in your application. If you change your project, you must notify us in writing and you may be required to send us a new application for a new certification. If the property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions listed in the attached certification as well as the additional conditions listed below: 1. An additional condition is that stormwater shall be directed to diffuse flow at non-erosive velocities through the protected stream buffers; 2. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or areas within 50 feet of all streams and ponds. These mechanisms shall be put in place within 30 days of the date of this letter or the issuance of the 404 Permit (whichever is later). A sample deed notification format can be downloaded from the 401 /Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands . 3. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401 Certification has been completed. If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 6714, Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please call Steve Mitchell or Debbie Edwards in our Raleigh Regional Office at 919-571-4700 or Cyndi Karoly in the Central Office at 919-733-9721. Questions regarding stormwater should be directed to Todd St. John at 919-733-9584. N. C. Division of Water Quality 1617 Mail Service Center Raleigh, NC 27699-1617 (919) 733-7015 Michael F.

As requested in NC-DWQ's initial correspondence regarding the project (see attached letter dated June 4th, 2002), S&EC forwarded information provided by the project engineer (CH Engineering) to address stormwater discharge/diffuse flow through buffers. Since this information was determined to be inadequate by NC-DWQ, the project engineer (CH Engineering) will resubmit the requested calculations and plans demonstrating that diffuse flow through the buffers will be achieved directly to NC- DWQ. Therefore, please do not consider the application withdrawn-rather, it should be considered to be on administrative hold pending the receipt of additional information that will allow the continued processing of the permit application.

It should be noted that in the preconstruction notification form (PCN) originally submitted, under Item XI (which discusses stormwater), it was erroneously mentioned that calculation tables provided by the project engineer were included in the application. These tables were not included in the application submitted to NC-DWQ. However, as indicated in the attached calculation tables provided here by the project engineer addressing stormwater issues, impervious surface acreage is estimated at 15 %, well below the established 30 % threshold requiring stormwater management plans.

We also request written concurrence from the NC Division of Water Quality (NC-DWQ) that the project complies with the 401-Water Quality Certification associated with Nationwide Permit 39, and that it complies with the Neuse River Riparian Buffer rules. A Pre-construction Notification Application (PCN) is attached, which includes an agent authorization form. S&EC performed a Neuse River Buffer evaluation for the site in fall 2000, and a detailed wetland delineation in April 2002, which was submitted to the USACE for approval on May 20th, 2002. Data forms for the delineation are attached. NC-DWQ confirmed S&EC's Neuse River Buffer evaluation (NBRRO 01-199-see attached). The proposed project, which consists of a residential subdivision, is located east of West Lake Rd. (SRI 387), west of Bells Lake Rd. (SR 1386), approximately one mile south of Ten-Ten Rd. (SR 1010) near Cary, Wake County, NC. Please refer to the USGS site snap. The property comprises approximately 32 acres, and is in the Neuse River Basin. Approximately 0.003 acres (1,278 ft.2) of jurisdictional wetlands and 85 linear ft. of stream channel will be impacted for a roadway crossing (Impact 1-see impact maps) under Nationwide Permit 39 (totaling 0.03 acres/85 linear ft.). Approximately 9,983 ft.2 (zone 1: 6,291 ft. 2, zone 2: 3,692 ft.2) of Neuse River Buffer will be impacted by the Charlotte Office: Greensboro Office: Hickory Office: 236 LePhillip Court, Suite C 3817-E Lawndale Drive 710 Boston Road Concord, NC 28025 Greensboro, NC 27455 Taylorsville, NC 28681 Phone: (704) 720-9405 Phone: (336) 540-8234 Phone (828)635-5820 Fax: (704) 720-9406 Fax: (336) 540-8235 Fax: (828) 635-5820 i r. r, - May 24th, 2002 proposed roadway crossings (Impact 1). Approximately 0.011 acres (495 ft.2) of jurisdictional wetlands and 20 linear ft. of stream channel will be temporarily impacted under NWP 12 (Impact 2-see impact maps). Total proposed impacts are 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft. temporary). The Town of Cary originally required two roadway crossings over the channel where proposed impacts will occur in order to preserve connectivity within the site-despite our client's wishes-who understood that the two crossings conflicted with avoiding and minimizing unnecessary impacts to wetlands/waters of the U.S. Thus, William Barker (our client), S&EC, and a project engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to discuss the crossing requirement. After this meeting, the project's land planner and engineer were able to convince Cary to drop one of the required roadway crossings, leaving the one proposed in this application, which is necessary to access high ground in the northeastern portion of the property. Additionally, DOT has relaxed the minimum turn radius requirement for the extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer impacts. It is important to note that the road shown entering the site on the northern property line is not yet constructed, and is a reserved road right-of-way-not a dedicated right-of=way. Thus, the road right-of-way is still owned by the adjacent site's developer. Additionally, there is a gas line easement parallel to the northern property line immediately adjacent to the property. The USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and may require compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification. The proposed roadway crossing is necessary in order to access high ground in the northeastern portion of the property. This road is an extension of a stubbed road on the western property line. Both the roadway and sewer line crossing, as evinced by the site plan, have been designed to cross wetland areas and the stream channel perpendicularly. A large, contiguous bottomland hardwood forest wetland in the middle of the property has been completely avoided, as have all other wetlands/waters of the U.S. onsite. NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts below 1 acre and 150 linear feet of significant channel per project. Because the proposed cumulative impacts resulting from the project total 0.0411 acres (0.011 acres temporary)/ 105 linear ft. (20 ft. temporary), project impacts are below the aforementioned thresholds, and S&EC believes that neither wetland nor stream channel mitigation should be required Additionally, NC-DWQ's current policy does not require mitigation for buffer impacts if they do not exceed 1/3 acre per buffered channel tributary. Because the proposed buffer impacts resulting from the project do not exceed the aforementioned threshold (9,983 ft.z or 0.229 acres), buffer mitigation should not be required. Because the proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than 40 ft. wide, it is considered an "exempt" activity by the Neuse River Basin Riparian Buffer Rules, and should not require riparian buffer mitigation.

Provide photocopies of previously issued permits, 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. S&EC performed a Neuse River Buffer evaluation for the site in fall 2000, and a detailed wetland delineation in April 2002, which was submitted to the USACE for approval on May 20`n 2002 Data forms for the delineation are attached. NC-DWQ confinned S&EC's Neuse River Buffer evaluation (NBRRO 01-199-see attached). No permits or jurisdictional determinations have been issued for the project at this time. V. Future Project Plans Are any additional permit requests anticipated for this project in the future? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application: No additional permit requests are anticipated for the project in the future. 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. 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. Page 5 of 12 1.

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.usgs.gov. Several internet sites also allow direct download and printing of USGS maps (e.g., www.tonozone.com, www.mapquest.com, etc.). Cumulative impacts (linear distance in feet) to all streams on site: 105 linear ft. (20 ft. temporary for sewer line crossing) 3.

List each impact separately and identify temporary impacts. Impacts include, but are not limited to: till, excavation, dredging, flooding, drainage, bulkheads, etc. 4. 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.): 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 Town of Cary originally required two roadway crossings over the channel where proposed impacts will occur in order to preserve connectivity within the site-despite our client's wishes-who understood that the two crossings conflicted with avoiding and minimizing unnecessary impacts to wetlands/waters of the U.S. Thus William Barker (our client), S&EC, and a project engineer from CH Engineering met with Bob Zarzecki of NC-DWQ in January to discuss the crossing requirement. After this meeting, the project's land planner and engineer were able to convince Cary to drop one of the required roadway crossings, leaving the one proposed in this application, which is necessary to access high ground in the northeastern portion of the property. Additionally, DOT has relaxed the minimum turn radius requirement for the extension of Alphawood Drive (see impact map) in order to minimize Neuse River buffer impacts The proposed road crossing (Impact 1) has been designed to cross the stream channel at a perpendicular angle to minimize impacts The proposed sewer line crossing (Impact 2) also has been designed to cross the stream wetland area and buffer perpendicularly to minimize impacts. 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 7 of 12 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/ncwetlands/strmgide.html. 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 USACE's current policy requires applicants to avoid and minimize wetland and stream channel impacts to the maximum extent practicable and compensatory mitigation to offset unavoidable losses of waters of the US when impacts exceed the requirements for notification. The proposed roadway crossing is necessary in order to access high ground in the northeastern portion of the property. This road is an extension of a stubbed road on the western property line, and crosses the stream perpendicularly, impacting as little channel as possible. The sewer line crossing is necessary to provide all portions of the property with sanitary sewer access. A large, contiguous bottomland hardwood forest wetland in the middle of the property has been completely avoided as have all other wetlands/waters of the U.S. onsite. NC-DWQ's current policy does not require mitigation for wetland and stream channel impacts below 1 acre and 150 linear feet of significant channel. Because the roposed cumulative impacts resulting from the project total 0.0411 acres (0.011 temporary)/ 105 linear ft. (20 ft. temporary-i a less than 1/3 acre and 150 ft) wetland or stream channel mitigation should not be required Page 8 of 12 Additionally NC-DWQ's current policy does not require mitigation for buffer impacts if they do not exceed 1/3 acrc per buffered channel tributary. Because the proposed buffer impacts resulting from the project do not exceed the aforementioned threshold (9,983 ft 2 or 0.229 acres) buffer mitigation should not be required. Because the proposed sewer line corridor will cross the riparian buffer perpendicularly and is less than 40 ft. wide it is considered an "exempt" activity by the Neuse River Basin Riparian Buffer Rules, and should not require riparian buffer mitigation. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP) with the NCWRP's written agreement. Check the box indicating that you would like to pay into the NCWRP. Please note that payment into the NCWRP must be reviewed and approved before it can be used to satisfy mitigation requirements. Applicants will be notified early in the review process by the 401/Wetlands Unit if payment into the NCWRP is available as an option. For additional information regarding the application process for the NCWRP, check the NCWRP website at http_//h2o.enr.state.nc.us/wry/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 Amount of Coastal wetland mitigation requested (acres): N/A IX. Environmental Documentation (DWQ Only) Does the project involve an expenditure of public funds or the use of public (federal/state/local) 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)9. 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 (DWQ Only) 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 Page 9 of 12 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 Neuse )? Yes ® No ? If you answered "yes", provide the following infortation: 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 (square feet) Multiplier Required Mitigation 1 6,291 3.0 N/A 2 3,692 1.5 N/A Total 9,983 N/A * Zone 1 extends out 30 feet perpendicular from near bank of channel; Gone 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, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0260. N/A XI. Stormwater (DWQ Only) Describe impervious acreage (both existing and proposed) versus total acreage on the site. Discuss stonnwater controls proposed in order to protect surface waters and wetlands downstream from the property. Impervious acreage on the site is not expected to exceed 30% (see attached calculation tables from project engineer); therefore a stormwater plan should not be required. X1I. Sewage Disposal (DWQ Only) 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. Connection to an existing sanitary sewer casement Page 10 of 12 X111. Violations (DWQ Only) 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. 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). ,5/ 2- ?

Proposed Tributary Dr. does not extend past our project. There is a reserved right-of-way and not a dedicated right-of-way north of the termination of Tributary Dr. on our site. Please be advised that a reserved right-of-way means that the Ownership of this particular right-of way is still held by the original developer. Also, there is a 50 ft. Colonial Pipe line right-of-way carrying three major gas transmission lines within the reserved right-of-way. The extension of Alphawood Dr. will be the only means of accessing the area north east of the proposed creek crossing. If you need additional information, please do not hesitate to let me know. ¦ PO Box 30128.

I told him that this crossing was required by both the County and Cary. I would recommend sending the PCN in as soon as possible to get the review process started. We may want to get all parties involved to meet, but go ahead and send it in so we can get started. - Bob Bob Zarzecki NC DENR/DWQ 401 Wetlands Certification Unit 919-733-9726 -qqqq Bob Zarzecki NC DENR/DWQ 401 Wetlands Certification Unit X19-733-9726 2321 Crabtree Blvd (office address) 1650 Mail Fax: 919-733-6893 Service Center (mail address) Work: 919-733-9726 Raleigh NC 27669-1650 Additional Information: Version 2.1 f \ !\ 1 ?
