In a letter dated December 11, 2003, the DWQ stated, "the ideal method to stabilize the stream would be an over all stream restoration plan beyond the two private areas addressed within your application". A letter from the City of Raleigh Stormwater Services Division dated March 12, 2003 was provided to the DWQ. This letter stated that the site "would likely not qualify for Wetland Restoration Program (WRP) funding because there is an insufficient length of severely eroded channel". It does not appear that WRP (now the Ecological Enhancement. Program (EEP)) was contacted regarding this stream. EEP staff may determine that the stream as a whole is unstable even though only a few areas contain "severely eroded channel" sections and therefore may be able to provide the funding needed to restore the stream. Also, the DWQ encourages you to search for other funding options to restore the stream beyond EEP. If funding is not available for restoring the stream, then the DWQ encourages you to find solutions to stabilize all severely eroding streambanks. Severely eroding streambanks can be a significant contributor of sediment (a major water quality pollutant) to our streams and other surface waters. The DWQ encourages the use of "soft" stabilization techniques such as grading with vegetated plantings over "hard" stabilization techniques such as riprap. The solution proposed by the City of Raleigh Stormwater Services Division in their letter to you dated October 2, 2003 may help to stabilize some of the severely eroding streambanks. Please note that this solution will require a new application, additional review and written concurrence from the DWQ beyond that approved within the March 4, 2004 approval letter.

PCN, Section VII. Impact Justification (Avoidance and Minimization) As stated in the Heathrow Stream Buffer Project Detail letter, this project is the result of an influx of storm water along the stream bed between the Heathrow common area and homeowners' property. We are proposing to mitigate erosion along the stream in several areas where the stream is encroaching on homeowners' property. These areas affect basically one homeowner out of 208 in our association. Our proposal to stabilize the stream bank in only two areas is a result of several factors. First, acting as a Homeowners Association we have minimal resources to apply to such a project. Therefore, we are trying to alleviate the problem in the most cost efficient manner as possible. Second, there is only one homeowner that is especially concerned about the erosion along the streambed in regards to its effect on their property. The other neighboring homeowners do not consider the erosion a threat, nor do they desire modifications to their property or property adjacent for mitigation of the erosion. Third, the location of the erosion is virtually unseen from the aspect of the community and has little use or access. Which leads to the next factor, access to the affected areas is limited. A large project or complete restoration of the stream would require the use of heavy machinery and equipment, which would severely impact surrounding neighbors properties as their properties would be used for access to the stream. Finally, it is believed that the ultimate resolution to the problem along the stream will not be served as a part of this project but will ultimately require additional patches and repairs in the future along this area or others downstream. The City of Raleigh should be required to help facilitate a stream buffer and retention pond to help alleviate the influx of stormwater along the stream due to the buildup of developments, roads and shopping centers in the area. PCN, Section X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) Project will impact protected riparian buffer within 15A NCAC 2B. 0233 (Neuse). Yes f-vi No I- Zone* Impact (square feet Multiplier Required Mitigation 1 300 3 900 2 NA 1.5 NA Total 300 900 *Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. Buffer mitigation: Payment to the Riparian Buffer Restoration Fund the sum of $864.00 (900 x $0.961sg. ft.). Stream Buffer Proposal 2: Overall, we are willing to work with the DWQ to construct a viable impact that serves as an environmentally friendly yet self-sustaining mechanism to improve the stream's bank stability at the proposed areas. Thus, we propose the following alternative to our initial hardened rip rap proposal. • Hand grade 2 areas of the stream bank adjacent to the property at 9212 Dakins Court of approximately 10'x 15' to a 2H:1V grade. • Apply a small amount of rip rap for a rock toe armor at base of grade where the bank meets the stream. Approximate rip rap area 15' wide x 2' high. Rip rap to be applied over filter fabric. • Apply tall fescue grass seed and fertilizer over graded bank. • Install fiber mesh over seeded graded bank. • Install live stakes of willow or other tree/shrub (<30 ft in height) with extensive rooting character and moisture tolerant at a rate of -2 stakes per square yard in a random pattern. Live stakes will be joint planted within the rock toe then dispersed randomly along the 15 foot sections to 4 feet from the top of the rock toe. • At the top of the graded bank (15' x 5' section of area), rooted stock of river birch or other tree (30 - 80 ft in height) with similar rooting character and location desirability. Two (2) of these taller trees will be planted at each project area. Note: The rip rap could be omitted, if not desired. It is our belief that the rip rap will assist the vegetation in taking root and becoming established within the bank.

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. VIII. Mitigation DWQ - In accordance with 15A NCAC 2I00, rr tgation 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.

As 1 mention in a previous conversation with you, my husband and I would prefer that the Homeowners Association move forward with the proposal from the City of Raleigh (see attached) and not go with an independent contractor and a "band aid" type solution. The City of Raleigh proposal is a comprehensive solution that will stabilize the entire bank and keep our property from falling into the stream. Our board President has resubmitted the permit to you with a revised proposal however, this is still just repairing two small sections of the bank aprox, 10 x 15 it where as the City's proposal wi] cover 181 ft. We also believe the President is attempting to mislead you with the statements made in his letter. 1. The letter states that they are "repairing several areas". This is not true. They are proposing to repair two small sections. 2. The letter states that the "HOA has minimal resources". This is also rot true. The HOA has over $30, 000 in reserves for projects just like this and through the city's cost share program they would only have to pay $9,800. 3. The letter states that "other homeowners do not sea this erosion as a throat". This is not true and not relevant. According to our Bylaws and a letter from their own attorney the HOA is responsible for the maintenance of the common area. The stream bank is on common area and if not repaired will start eating away at multiple property owners lot lines. 4. Finally the President makes a comment that the "City of Raleigh should be required to help facilitate a stream buffer and retention pond". I have already had both City and State engineers access this entire stream bank from Cub Trail to the Durant nature part( and the only solution offer was the City's Storm water Cost share program for the 181 ft of severely eroded stream bank. I am including the report that verifies my comments Sincerely, Sara & Mark Thomas JAN. -05' 04 (PION) 08:35 TEL:919 807 3421 _ I'. nn3 kepi y'Io; Cnv orkalctel Central t nplneenne Department - 221[1 Stormwater Services Dnvistop Post Offlcc bo% 5911 kalctpl1.

The property owners at 9209 and 9212 Daldns Court will be required to sign tite petition form as access to your property will be through these properties. In addition to submitting the petition form, the following information discusses requirements that must be met before any construction activities can be initiated to implement a solution to the drainage problem: S. All casements necessary to access the site and to perform construction activities for the drainage improvements must be granted to the City of Raleigh. 6. The following permits maybe necessary for this project: a. United States Army Corps of Engineers - Section 404 Wetlands Permit b. North Carolina Department of Environment and Natural Resources -Division of Water Quality Section 401 Water Quality Certification Permit and Neuse River Buffer Rules Permit c. City of Raleigh Conservation Engineering Division - Erosion Control Permit and Flood Permit d. Federal Emergency Management Agency - Flood Mapping Permit Our office will determine which permits will be necessary for the work to address your drainage problem and will apply for any necessary permits only following receipt of a petition and City Council approval of the petition. Please note that if any of the above-listed regulatory agencies request a change in the proposed design, or if compensatory mitigation is required by the Division of Water Quality this will affect the Preliminary Cost Estimate. 7. The Preliminary Cost Estimate for this project is $29,800.00. This estimate includes all materials and labor to complete the work and includes both the "City Right-of-Way Costs" and the "Work on Private Property Costs" previously described. The City's share of the estimated costs is $20,900.00, and the property owner's share of the estimated costs is $9,800.00. Payment is not required until after the City Council reviews and approves the petition. JAN. -05' 04 (h10N) 08:36 mr. White October 2, 200; Page Three TGL:919 80' 3421 11. 005 Following City Council approval of a petition, the petitioner is required to make a 10 deposit of the property owner's estimated costs within 30 days of the date of approval. The 10 0/1, deposit for this proiect will be 5980.00. Please note that this deposit will not be refundable if the City will incur costs for surveys, dratting or design work for this project. The remaining 90 of the property owner's estimated costs, which is $5,820.00, is to be paid when the property owner and the City execute a written agreement providing for the construction of the proiecl. Instead of paying the remaining 90 % of the property owner's costs as a lump sum, a petitioner may elect to pay in installments as described in the "City Storm Drainage Policy," Section 6.o.(2). If you wish to pay the property owner share by installment payments, please note this on the petition form. Please note that it is difficult for a homeowner's association to qualify for installment payments. A security in the amount of the loan would be required. Please note that all "City Storm Drainage Policy" petition projects must be approved by the City Council and construction is required to be performed under City contract and supervision. Projects not meeting these requirements will not be eligible for technical design or funding assistance through the "City Storm Drainage Policy." Also, the City Council may approve, reject or modify any petition proposal based upon its considerations of relative priorities and funding. It should be further noted that this letter is intended to briefly discuss and explain the "highlights" of the "City Storm Drainage Policy." Please review carefully the "City Storm Drainage Policy" for all other provisions and requirements of the "City Storm Drainage Policy." If you wish to petition the City Council for assistance with this drainage project, please sig.,bri the petition form and return it in the enclosed self-addressed stamped envelope. I must receive your signed petition form by January 31, 2003 in order to process the petition so that it may be submitted to the City Council. Please note that the City Council reviews proposed drainage petition projects two times each year - in February and July. Each project may be approved, disapproved, modified or held until the next review period by the City Council.

Problem: Severe Erosion H. Preliminary Design Information: A. The site is not located in a flood prone area according to the City of Raleigh's flood hazard soils maps. B. Drainage Area - 212 Acres III. Solution and Cost Estimate: A solution to this problem would involve stabilizing approximately 181 feet of severely eroded creek bank adjacent to 9212 Daldns Court. At the owners' request, this estimate is for stabilizing only the west side of the creek bank. The west bank of the creek will be sloped to a 2:1 grade, the toe and lower portion of the bank will be stabilized with class II rip rap stone. The upper portion of the creel: bank will be stabilized with biodegradable matting and vegetation. The total project cost is estimated to be $29,900.00. IV. Application of the City Storm Drainage Policy to the Problem: Section 2 of the City Storm Drainage Policy allows the City to assist private property owners with drainage problems associated with streams causing severe erosion or structural flooding. This section of the City Storm Drainage Policy would allow the City to assist the property owner. V. Priori , Level: This drainage problem is a Priority Level 5.4 in accordance with the attached priority schedule. VI. Funding Availability: This problem is eligible for technical design and funding assistance in accordance with the City Storm Draina Policy. Cost sharing between the City and the private property owner such that portions of the project on priv.- property associated with hardened structures or pipes will be a 50 % City / 50 % Private Property Owner cost sha. and costs associated with installation of rip rap stone on private property will be a 66.67 OX0 City / 33.33 % PrivE Property Owner cost share. All costs within the City Right-of-Way will be funded 100 % by the City. The cost she amounts are $9,800.00 for the Private Property Owner's share and $20,900.00 for the City's share. VII. Limitations: The proposed solution and associated cost estimate in this report are based on preliminary investigation and did not involve detailed field survey work. Therefore, the proposed solution and cost estimate are subject to reasonable modifications. However, final design plans to address the drainage problem cannot be developed until the City receives a signed petition, a 10 % down payment of the private property owner's cost share, and the City Council approves the petition and estimated cost for this project.

The purpose of the site investigation was to evaluate the condition of the stream channel as it related to erosion along the crock banks. We also looked at culvert crossings of the asphalt greenway trail to discern whether remedial or maintenance actions would be required for the culvert crossings. Observations determined that this reach of stream channel is experiencing some of the characteristics of channel modification as a result of the urbanization of the watershed. There were, however, only a few select areas where severe erosion was observed. The stream reach between Cub Trail and Camp Durant Park Entrance Road would likely not qualify for Wetland Restoration Program (WRP) funding because there is an insufficient length of severely eroded channel to meet the North Carolina Division of Water Quality criteria for WRP funding. Areas on private property that are not affecting the Parks and Recreation Department greenway trail and area experiencing severe streambank erosion may qualify for cost-share assistance through the City Storm Drainage Policy. The areas of severe erosion that were observed were predominantly in the vicinity of the greenway trail and could be stabilized by the Parks and Recreation Department where it might affect the greenway trail. The majority of the length of the stream channel in the reach investigated was relatively stable and reflected a typical eastern Piedmont urban stream. Please advise if I may be of further assistance.

NC 21615 In reply to your request for additional information regarding our application to complete a stream stabilization project in Wake County, the desired information follows below along with the associated attachments. PCN, Section VII. Impact Justification (Avoidance and Minimization) As stated in the Heathrow Stream Buffer Project Detail letter, this project is the result of an influx of storm water along the stream bed between the Heathrow common area and homeowners' property. We are proposing to mitigate erosion along the stream in several areas where the stream is encroaching on homeowners' property. These areas affect basically one homeowner out of 208 in our association. Our proposal to stabilize the stream bank in only two areas is a result of several factors. First, acting as a Homeowners Association we have minimal resources to apply to such a project. Therefore, vie are trying to alleviate the problem in the most cost efficient manner as possible. Second, there is only one homeowner that is especially concerned about the erosion along the streambed in regards to its effect on their property. The other neighboring homeowners do not consider the erosion a threat, nor do they desire modifications to their property or property adjacent for mitigation of the erosion. Third, the location of the erosion is virtually unseen from the aspect of the community and has little use or access. Which leads to the next factor, access to the affected areas is limited. A large project or complete restoration of the stream would require the use of heavy machinery and equipment, which would severely impact surrounding neighbors properties as their properties would be used for access to the stream. Finally, it is believed that the ultimate resolution to the problem along the stream will not be served as a part of this project but will ultimately require additional patches and repairs in the future along this area or others downstream. The City of Raleigh should be required to help facilitate a stream buffer and retention pond to help alleviate the influx of stormwater along the stream due to the buildup of developments, roads and shopping centers in the area.

Stream Buffer Proposal 2: Overall, we are willing to work with the DWQ to construct a viable impact that serves as an environmentally friendly yet self-sustaining mechanism to improve the stream's bank stability at the proposed areas. Thus, we propose the following alternative to our initial hardened rip rap proposal. • Hand grade 2 areas of the stream bank adjacent to the property at 9212 Dakins Court of approximately 10'x 15' to a 2H:1V grade. • Apply a small amount of rip rap for a rock toe armor at base of grade where the bank meets the stream. Approximate rip rap area 15' wide x 2' high. Rip rap to be applied over filter fabric. • Apply tall fescue grass seed and fertilizer over graded bank. • Install fiber mesh over seeded graded bank. • Install live stakes of willow or other tree/shrub (<30 ft in height) with extensive rooting character and moisture tolerant at a rate of -2 stakes per square yard in a random pattern. Live stakes will be joint planted within the rock toe then dispersed randomly along the 15 foot sections to 4 feet from the top of the rock toe. • At the top of the graded bank (15'x 5' section of area), rooted stock of river birch or other tree (30 - 80 ft in height) with similar rooting character and location desirability. Two (2) of these taller trees will be planted at each project area. Note: The rip rap could be omitted, if not desired. It is our belief that the rip rap will assist the vegetation in taking root and becoming established within the bank.

Approval from DWQ is required to disturb these areas. Please provide 7 copies of the following information and refer to the DWQ # listed above in your reply. Please show these on maps of suitable scale (for instance 1" = 100 feet) so we can begin to determine your projects' compliance with 15A NCAC 2H.0500. Please complete Sections VII and X on the application. It appears that impacts to the buffer can be avoided or minimized. Please propose a method other than hardening of the streambank (such as grading with vegetative planting). The DWQ believes that the ideal method to stabilize the stream would be an over all stream restoration plan beyond the two . private areas addressed within your application. Please telephone Bob Zarzecki at 919-733-9726 if you have any questions or would require copies of our rules or procedural materials. This project will remain on hold as incomplete in accordance with 15A NCAC 2H.0505(c). The processing time for this application will begin when this information is received. If we do not hear from you by writing or by fax at (919) 733-6893 within three (3) weeks we will assume you no longer want to pursue the project and will consider it withdrawn.

The Ultra-Amazing Standard Additional Conditions Document Version 1 - June 1, 2003 The blue wording is for your instruction and edification (i.e. don't put this in the approval, ok?). The red wording is optional lingo (don't forget to change the color to black if used or to delete if not used). Also, please change the dollar signs to the appropriate number in the final document. The little gray boxes need to be filled with the appropriate information. Please note the handy dandy titles that Bob inadvertently came up with should be used... Impacts should be specifically listed and specifically referenced. This is necessary to ensure that only the impacts approved are conducted and that if any impacts beyond those specifically approved occur it will be easier to enforce the 401 Cert./Isolated Wetland Permit/Buffer Approval. Taking this extra bit of time now saves headaches later. $$) Impacts Approved ? The following impacts are hereby approved as long as all of the other specific and general conditions are met. No other impacts are approved including incidental impacts: Amount A roved Units Plan Location or Reference Stream feet C.. 404/CAMA Wetlands acres Waters acres Buffers (square ft. Mitigation may be necessary when mitigation thresholds are exceeded or when certain buffer impacts are conducted. The USACE may require mitigation in certain circumstances that are below our threshold requirements or for the impounded portion of streams for instance when DWQ does not. In those cases we cannot require mitigation. However, when DWQ does require mitigation it is recommended that our requirements be similar to the USACE's. For streams it is anticipated that DWQ will follow the USACE's Stream Mitigation Guidelines. For wetlands we typically require at least 1:1 restoration or creation. The following condition can apply to applicants that propose on site mitigation such as stream relocation where the relocation will meet the definition of stream restoration (i.e. the activity will mitigate for its own impacts). Remember to apply the ratios to the amount of mitigation required. ? Compensatory Mitigation Mitigation must be provided for the proposed impacts as specified in the table below. A final compensatory mitigation plan must be approved in writing by this Office before any of the impacts approved herein are conducted. Additionally, the compensatory mitigation plan must be completely constructed and implemented according to the plans approved by this Office before any permanent building [road] associated with the project is occupied [is opened]. The mitigation must be maintained according to the approved plan and permanently protected by the use of conservation easements or similar protections. Any repairs or adjustments to the mitigation site must be made according to the approved plan or must receive written approval from this Office to make the repairs or adjustments. Compensatory Mitigation Required Stream feet Wetlands acres Waters acres Buffers (square feet The following are recommended in addition to the above when on site stream mitigation, relocation or restoration is proposed: ? Stream Relocation (Mitigation) with Approved Plans The stream and buffer relocation must be constructed, maintained, and monitored according to the approved plans in the application and application modifications. Any repairs or adjustments to the site must be made according to the approved plans or must receive written approval from this Office to make the repairs or adjustments. ? In order for this project to be used as compensatory mitigation for other specific projects you must obtain written approval from this Office. The request should include the amount of stream length and buffer area credit requested for accounting purposes. Please specify DWQ project No. when making your request. ? Stream Relocation/Stabilization (Mitigation) that Require Additional Approved Plans ? Include bold line material Before any of the impacts authorized in this Certification occur, you must provide and receive written approval from this Office for a final stream relocation and/or stabilization plan. The plan must include designs and specifications that meet the definition of stream restoration (or enhancement in no relocation is proposed) according to the latest version of the internal Technical Guide for Stream Work in North Carolina (available at http://h2o.ehnr.state.nc.us/ncwetlands/strmgide.htm]). The stream and buffer relocation must be constructed, maintained, and monitored according to the plans approved by this Office. Any repairs or adjustments to the site must be made according to the approved plans or must receive written approval from this Office to make the repairs or adjustments. The relocated stream must be preserved in perpetuity by use of a conservation easement or other similar mechanism as part of the approved plans. The following mitigation condition can be applied when the applicant has proposed and received approval to use the WRP, EEP, or mitigation bank- Obviously you will have to change references to the WRP If the EEP or a mitigation bank is used. ? Compensatory Mitigation Using the Wetlands Restoration Program (WRP) Mitigation must be provided for the proposed impacts as specified in the table below. We understand that you wish to make a payment to a fund administered by the NC Wetlands Restoration Program (WRP) to meet this mitigation requirement. This has been determined by the 'Nq. DWQ to be a suitable method to meet the mitigation requirement. This contribution will satisfy our compensatory mitigation requirements. Until the W RP receives and clears your check (made payable to: DENR - Wetlands Restoration Program Office), no impacts specified in this Authorization Certificate shall occur. Mr. Ron Ferrell should be contacted at (919) 733-5208 if you have any questions concerning payment into the WRP. You have one month from the date of this approval to make this payment. For accounting purposes, this Authorization Certificate authorizes payment Into the Riparian Buffer Restoration Fund to meet the following compensatory mitigation requirement: Compensatory Mitigation Required River and Subbasin Number Stream feet Wetlands acres Waters acres Buffers (square feet The following condition is recommended when a stormwater management plan is required. This typically applies to projects that are over 30% Impervious or have concentrated areas of development vgthin a project that are over 30% Impervious. It Is recommended that the need for a stormwater management plar?bli-btt5 bllt icb'pfibr?.to A96rrig any approvals. The applicagt should also demonstrate that there are adequate space allotted for the proposed BMP and that a BMP appropriate to the stream classification Is used (I.e. wetlands, pond with forested filter strip, or bioretention in sensitive watersheds per the GC's). ? Written Stormwater Management Plan (Final Plan Needed) An additional condition is that a final, written stormwater management plan (including a signed and notarized Operation and Maintenance Agreement) shall be approved In writing by this Office before the impacts specified in this Certification occur per Condition No. in GC No. . The stormwater management plan must include plans and specifications for stormwater management facilities that are appropriate for surface waters classified as and designed to remove 85% TSS according to the most recent version of the NC DENR Stormwater Best Management Practices Manual. These facilities must be designed to treat the runoff from the entire project, unless otherwise explicitly approved by the Division of Water Quality. Also, before any permanent building is occupied at the subject site, the facilities (as approved by this Office) shall be constructed and operational, and the stormwater management plan (as approved by this Office) shall be implemented. The structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality. ? (Optional Paragraphs) The above condition shall apply unless it is demonstrated in writing to the satisfaction of this Office that the impervious area of the entire, built-out project shall be less than 30% and that there are no areas of concentrated impervious area over 30% within the project such as, but not limited to, commercial areas, multi-family, clubhouses, maintenance areas, etc. There shall be no direct discharges to streams from fairways, tee areas, or greens. A State Stormwater Permit (15 A NCAC 2H .1000) can be considered to meet this condition. ? Written Stormwater Management Plan (No Further Approval Needed) ? Include bold line material The final, written stormwater management plans (including a signed and notarized Operation and Maintenance Agreement) dated , must be Implemented and the stormwater management facilities shall be constructed and operational before any permanent building is occupied at the subject site. The structural stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No changes to the structural stormwater practices shall be made without written authorization from the Division of Water Quality. The following conditions can be used In any situation where diffuse flow Is required through protected buffers. The first condition can be used for projects that have adequately addressed this issue as part of the application process. The second can be used when the Issue Is not well addressed. ? Diffuse Flow (No Review) An additional condition is that all constructed stormwater conveyance outlets shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers such that it will not re-concentrate before discharging into a stream as identified within 15A NCAC 2B .02 (5). If this is not possible it may be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require additional approval from this Office. ? Diffuse Flow (Review) An additional condition is that all constructed stormwater conveyance outlets shall be directed to flow in a diffuse manner at non-erosive velocities through the entire protected stream buffers without re-concentrating. If this is not possible it may be necessary to provide stormwater facilities that are considered to remove nitrogen. Additionally, a stormwater management plan for this project shall be provided to this Office before any of the impacts approved herein are conducted. The plan shall specify all stormwater discharge points, plan details, and calculations to indicate that diffuse flow through the protected buffers or nitrogen removal as described above will be achieved. The following are typical conditions added to all approvals unless it does not make sense to add it: ? Certificate of Completion .. Upon completion of all work approved within the 401 Water Quality Certification or applicable Buffer Rules, and any subsequent modifications, the applicant is required to return the attached certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650. ? Deed Notifications Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands, waters and protective buffers in order to assure compliance for future wetland, water and buffer impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or buffers approved for impact under this Certification Approval and Authorization Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site at httpJ/h2o.enr.state.nc.us/ncwetlands. ? Temporary Fills All temporary fill and culverts shall be removed and the impacted area returned to the original grade, including each stream's original cross sectional dimensions, planform pattern, and longitudinal bed and bed profile after construction Is complete or within 6 months of the establishment of the crossing, which ever is sooner, and the various sites shall be stabilized with natural woody vegetation (except for the maintenance areas of permanent utility crossings) and restored to prevent erosion; If the crossings are not completely removed and restored as described above within the specified time above, additional written approval from this Office must be obtained to modify this condition. The following are conditions to place specific requirements In areas with protected buffers: Protective Fencing The outside buffer, wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked by orange fabric fencing for the areas that have been approved to infringe within the buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 213 and GC ? Catawba Buffer Tree Protection No trees shall be removed from Zone 1 of the Catawba Buffer unless they are directly within the construction access corridor. If trees are removed, forested vegetation shall be re-established within the construction access or other temporary Impact area occurring in the protected buffer zone within the next growing season following construction of the project; The following are additional conditions for additional sediment and erosion control practices: ? Sensitive Watershed Erosion and Sediment Control Practices The Division of Land Resources' Design Standards in Sensitive Watersheds (15A NCAC 04B .0124) must be adhered to throughout the life of this project. ? NC DOT Sensitive Watershed Erosion and Sediment Control Practices Sediment and erosion control measures shall adhero to the design standards for sensitive watersheds [15A NCAC 46 .0024]; see NCDOT publication, Best Management Practices for the Protection of Surface Waters (March 1997); ? Turbidity Standard The turbidity standard of NTUs (Nephelometric Turbidity Units) shall not be exceeded as described in 15 A NCAC 2B..0200. Appropriate sediment and erosion control practices must be used to meet this standard. The following are various special conditions for additional protection of various resources. They can be tweaked to meet specific circumstances: ? Culvert Installation The culverts required for this project shall be installed in such a manner that the original stream profiles are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and longitudinal profile) are to be maintained above and below locations of each culvert. The culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed correctly. The culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section dimensions, pattern and longitudinal profile) are to be maintained above and below locations of each culvert. As such, it is required that you provide the plans with adequate details that indicate that the current stability of the stream will be maintained or enhanced. You must receive written approval from this Office for the above plans before the culvert(s) is Installed. The culvert(s) must be installed according to the approved plans. The establishment of native, woody vegetation and other soft stream bank stabilization techniques must be used where practicable instead of rip rap or other bank hardening methods; If rip-rap is necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of Water Quality. Installation of culverts in wetlands must ensure continuity of water movement and be designed to adequately accommodate high water or flood conditions. Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of Completion" form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please send photographs upstream and downstream of each culvert site to document correct installation along with the Certificate of Completion form. ? Minimum Release Before any of the impacts approved in the Certification are conducted you must submit, and obtain written approval by this Office for, a minimum water release plan. The plan must include a written explanation of the specific discharge rate and means for each required release. The plan must also include any design specifications, details and calculations to show that the release shall be achieved in the given conditions. The plan shall also include monitoring that ensures compliance. The plan and any associated facilities, once approved, must be in place and implemented upon the completion of ?

Pan 12 of 12 ASeptember 15, 2003 RE: Heathrow Stream Buffer Project - 401 Permit NC Division of Water Quality Wetlands Unit 2321 Crabtree Blvd, Ste 250 Raleigh, NC 27604 To Whom It May Concern: 9200 Dakins Court Raleigh, NC 27615 The Heathrow Stream Buffer project is the result of an influx of storm water along the Simms Branch stream bed. As storm water has increased in recent years the stream has begun to erode severely and eat away at its banks. This project is to reinforce two 150 square feet areas along the stream, which lie adjacent to a homeowner's property at 9212 Dakins Court, Raleigh, NC. As the banks erode the stream is encroaching on the homeowner's property from the Heathrow Homeowner's Association's common area. Therefore, we propose this project to deter further erosion into the homeowner's lot. Refer to the "Heathrow Stream Buffer" drawing, Details 'A' and 'B,' for plans and further details of the project. Specifications of the project are: • Hand grade approximately two 15 linear feet sections of the stream bed to approximately a 2:1 ratio of bank incline. (i.e. The current bank is --5 feet deep, therefore the bank will be graded -10 feet back from the current edge.) • Install fabric over the graded banks. • Install Class II Rip Rap over fabric. This work will be completed to stabilize the propose stream banks and deter further erosion. It will not modify the current path of the stream. If you have questions regarding this project or need additional information, please feel free to contact me at 878-2989. Sincerely, GV, vI /,7- Kevin W. White, P.E.

Page 12 of 12 September 15, 2003 RE: Heathrow Stream Buffer Project - 401 Permit NC Division of Water Quality Wetlands Unit 2321 Crabtree Blvd, Ste 250 Raleigh, NC 27604 To Whom It May Concern: 9200 Dakins Court Raleigh, NC 27615 The Heathrow Stream Buffer project is the result of an influx of storm water along the Simms Branch stream bed. As storm water has increased in recent years the stream has begun to erode severely and eat away at its banks. This project is to reinforce two 150 square feet areas along the stream, which lie adjacent to a homeowner's property at 9212 Dakins Court, Raleigh, NC. As the banks erode the stream is encroaching on the homeowner's property from the Heathrow Homeowners Association's common area. Therefore, we propose this project to deter further erosion into the homeowner's lot. Refer to the "Heathrow Stream Buffer" drawing, Details 'A' and 'B,' for plans and further details of the project. Specifications of the project are: • Hand grade approximately two 15 linear feet sections of the stream bed to approximately a 2:1 ratio of bank incline. (i.e. The current bank is -5 feet deep, therefore the bank will be graded -10 feet back from the current edge.) • Install fabric over the graded banks. • Install Class II Rip Rap over fabric. This work will be completed to stabilize the propose stream banks and deter further erosion. It will not modify the current path of the stream. If you have questions regarding this project or need additional information, please feel free to contact me at 878-2989. Sincerely, GUS%.??' ` Kevin W. White, P.E.
