As you requested, I have removed the filter strips from the wetlands areas at Site #I and Site #2, which eliminates excavation of the wetlands and allows the wetlands area to treat the stormwater prior to its entry into the buffer. At Site #1, a level spreader has been added prior to the wetlands to provide diffuse flow. I have attached a level spreader detail recommended by Mr. Bob Zarzecki with proposed dimensions and notations. A preformed scour hole (plunge pool) has been added at Site #2, and the proposed 30" RC pipe at this location has been replaced with two smaller pipes, as you requested. I have also attached the preformed scour hole detail with proposed dimensions and notations. Detail drawings of the level spreader and the preformed scour hole have been added to the construction drawings. I trust that these revisions are sufficient to meet your requirements. Your earliest review and response would be greatly appreciated. Please feel free to contact me if you have any questions or need additional information. Thank you for your assistance.

The DWQ has determined that your application was incomplete and/or provided inaccurate information as discussed below. On November 12, 2003, the DWQ received your additional information dated November 6, 2003. The DWQ discussed this information with you on November 24, 2003 in which you stated that you plan to redesign the project to better comply with DWQ regulations. The DWQ will require additional information in order to process your application to impact protected wetland, streams and/or buffers on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will place this project on hold as incomplete until we receive this additional information. Please provide the following information'so that we may continue to review your project. Additional Information: 1. It is not clear in your plans how you intend to comply with the diffuse flow requirement of the Neuse Buffer Rule [15A NCAC 02B .0233(5)]. 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, the DWQ requires that a stormwater management plan for this project be submitted in order to complete the review of your application. 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. 2. It appears that your proposed plans to create a ditch/swale through jurisdictional wetlands may potentially drain the jurisdictional wetlands. Please provide justification as to how your project will not drain jurisdictional wetlands.. (You may choose to evaluate the potential of discharging (via sheet flow) stormwater into the jurisdictional wetlands without excavating through the wetlands.) 3. The DWQ understands that you plan to redesign your project to better comply with DWQ regulations. . Please note that your project will remain on hold until we receive this additional information.

To address water quality issues, we have proposed filter strips to remove nitrogen. We are also providing decreased stormwater velocities and diffuse flow before the buffer with the proposed level spreaders and temporary rock check dams. In light of the fact you appear inclined to deny my client's request, I respectfully submit the following. We submitted the PCN Application on June 13 of this year. My client received US Army Corps of Engineers approval (NWP 39) for ditching and draining 0.48 acres of wetlands approximately two weeks after submittal. On September 11, we received a letter from your office dated August 14 that requested more information. The date of your letter indicates that it took almost one month for the letter to get from your office in Raleigh to our office in Garner. I sent you a fax with the additional information you requested on September 24 and then placed the original in the mail. Almost six weeks passed without a response from you until I contacted you this week. Though the Corps of Engineers approved our proposal to place filter strips through the wetlands more than three months ago, you informed me that you are inclined to deny the request because of the wetlands impact. I understand that USACE approval does not necessarily coincide with or indicate DWQ approval, but for three months now my client has been expecting your approval as well. He has missed the majority of the construction season this year while waiting for this final permit from DWQ. Your earliest review and response would be greatly appreciated.

In response to your letter dated August 14, 2003 and received by my office on September 11, 2003, please find attached the additional information requested for the subject project. I have included the Buffer Impact Justification that was submitted with the PCN for your reference. As the Justification outlines, the existing berm and access road located in the riparian buffer for Moccasin Canal do not allow for the conversion of concentrated flow into diffuse flow before the buffer. Storm drain pipes are proposed to be installed through the berm to prevent standing water. Though the Town of Selma and the developer desire installation of storm drain from the street outlets to the buffer, vegetated filter strips are proposed instead to provide nitrogen removal. I have attached calculations detailing the design of the filter strips at each site that I hope will be of assistance in your further review. Please note that the calculations for the Site # 2 filter strip require a bottom width of 22 feet to meet design standards. Although this filter strip can be constructed to design dimensions, we would prefer for aesthetic reasons to reduce the bottom width and add additional measures to slow velocity or remove nitrogen at your recommendation (check dams, different grass or plant material, etc.). Your consideration of this request is appreciated Please feel free to contact me if you have any questions or need additional information. Thank you for your assistance. Sincerely, Lee R. Hines, Jr. (Richie), PE Attachments LRH/ cc: Mr. Steve Mitchell 201 GLEN ROAD GARNER, NORTH CAROLINA PHONE: 919-773-0183 / FAX: 919-773-0148 Wetlands and Riparian Buffer Impact Justification Bayleaf Point Subdivision Selma 'T'ownship, Johnston County Background Information The current land use of the subject property is cutover woods and agricultural fields. The property is bounded on the west side by Moccasin Creek canal. Moccasin Creek was channelized approximately 25 years ago to help alleviate flooding problems in the Selma area. The spoil material from the channelization was placed on the east side of the creek, which created a berm along the west side of the subject property. No drainage pipes were installed in the.berm to allow the adjacent property to drain. This damming effect created the wetland area that now exists on the property. Prior to channelization of Moccasin Creek, the subject property naturally drained to Moccasin Creek. Proposed Impacts The proposed impacts to the wetlands and riparian buffer consist of construction of grass lined swales and storm drain pipes perpendicular to Moccasin Creek, to convey stormwater from the proposed residential development to the creek. To minimize impacts, only two stormwater outlets are proposed. The stormwater outlets are necessary to prevent flooding of the homes within the proposed development. No streets or other improvements are proposed within the wetland or riparian buffer areas. Justification/Minimization The existing berm along Moccasin Creek does not allow for converting concentrated flow to sheet flow before entering the buffer. The Town of Selma will take over maintenance of the stormwater facilities after construction. They desire that the stormwater be piped all the way to the creek for maintenance purposes. The developer would also prefer this to avoid additional standing water, which will attract mosquitoes and provide a negative appearance. However, to provide treatment of the stormwater before entering the creek, vegetated filter strips are proposed between the outlets at the street, and the culverts under the berm. The culverts are required under the berm because the berm is used as an access road to otherwise landlocked property, and for maintenance of the canal. Impacts to Zone 1 of the riparian buffer will be minimal because this area is already cleared and is being maintained as an access road. The Zone2 area will be revegetated with grass after construction. The total disturbance to the wetland areas will be limited to approximately 0.10 acres. No mitigation is proposed for the buffer or wetland impacts because the wetlands impacts are less than 1/3 acre, and the riparian buffer is already disturbed with an access road. The disturbance of the buffer and wetlands is required due to channelization of Moccasin Creek and subsequent berm construction, which created a hardship on the property owner. Filter Strip Calculations Filter Strip design requirements are taken from the Johnston County Stormwater Design Manual. Once properly constructed, periodic inspections will be made to insure that all gullies and eroded areas are repaired and that the grass is being maintained at the correct height to facilitate function of the strip. Site # 1 Requirement 1: Velocity entering the filter strip may not exceed 1 fps during the 10-Year Storm. Flow enters the filter strip through a RC pipe accepting stormwater flow from the proposed street. Use the Rational Method to calculate the flow during the 10-Year Storm. Calculate Qio Qio = C Iio A Rational Method Qio = (0.45)(6.13 in/hr)(0.39 acres) Qio =1.08 cfs Calculate Entrance Velocity Q= V A Rearrange to V= Q/ A In Site # 1, the pipe outlets into a short ditch section prior to entering the filter strip. Use the Normal-Depth Procedure (description attached), an iterative process based on Manning's Equation, to calculate the depth of flow at a given ditch cross section. The depth of flow is used to calculate the cross-sectional area of flow, which is then used to calculate the velocity of flow entering the filter strip. Iterations show that the velocity of flow is equal to approximately 1 fps when the bottom width of the ditch is 5 feet. Once the velocity is slowed through this initial outlet ditch section of 5 foot bottom width, the outlet ditch transitions into a filter strip of dimensions as indicated. Requirement 2: The bottom width of the filter strip is determined by the width of flow in the 2-Year Storm at a flow depth of 0.5 feet. Calculate Q2 Q2 = C I2 A Rational Method Q2 = (0.45)(4.76 in/hr)(0.39 acres) Q2 = 0.84 cfs Use Depth-Limited Procedure to Determine the Bottom Width Iterations show that the bottom width is approximately 2.7 feet in the 2-Year Storm with 0.5 feet flow depth. Use 3.0 feet as final dimension for ease of construction. Requirement 3: The velocity in the filter strip shall be less than 2 fps in the 10-Year Storm. V=Qio/A Calculate A A=By+My2 A = (3)(0.5 ft) + (3)(0.5 ft)2 A = 2.25 sf V 1.08 cfs / 2.25 sf = 0.48 fps 0.48 fps < 2 fps OK Final Filter Strip Dimensions at Site # 1 Bottom Width: 3 feet 3:1 Side Slopes 0.5% Slope Length: Minimum of 20 feet since the filter strip slope is less than 1.0 % Site # 2 Requirement l: Velocity entering the filter strips may not exceed 1 fps during the 10-Year Storm. Flow enters the filter strips through RC pipes accepting stormwater flow from the proposed street. A rip rap energy dissipator is proposed to create a non-erosive velocity into the filter strip.

As the rustification outlines, the existing berm and access road locoed in the riparian buffer for Moccasin Canal do not allow for the conversion of concentrated flow into diffuse low before the buffer. Storm drain pipes are proposed to be nwtalled through the berm to prevent standing water. Though the Town of Selma and the developer desire installation of stonn dmn from the suwt outlets to the buffer, vegetated filter strips are proposed instead to provide nitrogen removal. I have attached ealruLWons detailing the design of the filter strips at each site that I tiptoe will be of assists= in your £mther review- Please note that the calculations for the Sitc # 2 filter snip require a bottom width of 22 feet to meet design standards- Althougb this filter strip can be constructed to design dimensions, we would prefer for aesthetic reasons to reduce the bottom width and add additional measures to slow velocity or remove nitrogen at your recom meodation (check dams, di$erent grass or plant material, etc.). Your consideration of this request is appreciated- Please feel free to contact me if you have any questions or need additional information. Tbank you for your assistance. sincerely, I= R. Nines. Jr. Mkhie), M Attachments LRIV cc: Mr. Steve Mitchell 10002 201 GLEN ROAD GARN-R, NORTH CAROLINA FHOVE: 919-773-0183 / FAX: 919-773-01,48 09/24/03 12:54 FAX 919.773 0148 SOUTHWIND SURVEYING 10003 7 Wetlands and ]Riparian Buffer Impact Justification Dayleaf Point Subdivision Selma Township, Johnston County Backgroiind Information The current laud use of the subject property is cutover woods and agricultural fields. The property is bounded on the west side by Moccasin Creek canal. Moccasin Creek was channelized approximately 25 years ago to help alleviate flooding problems i-u the Selma area- The spoil material from the rnhanndization was placed on the east side of the creep, which created a berm along the west side of the subject properiy_ No drainage pipes were installed in the berm to allow the adjacent property to dram This damming effect created the wetland area that now exists on the property- priorto channelizatiou of Moccasin creek the subject property naturally drained to Moccasin Creek. Proposed Impacts The proposed impacts to the wetlands and riparian buffer consist of construction of grass lined swales and storm drain pipes perpendicular to Moccasin Creep to convey stormwater from the proposed residential, development to, the creek To minimize impacts, only two stounwater- outlets are proposed. The stormwater outlets are necessary to prevent flooding of the homes within. the proposed development_ No streets or other improvements are proposed within the wetland or riparian buffer areas. Justification/Mini m, zation The existing berm along Moccasin Creak does not allow for conv erring concentrated low to sheet flow before entering the buffer. The Town of Selma will take over maintenance of the stormwater facilities after construction. They desire that the stormwater be piped all the way to the creek for maintenance purposes. The developer -would also prefer this to avoid additional standing water, which will attract mosquitoes and provide a negative appearance. However, to provide treatment of the stormwater before eatering the creep vegetated filter strips are proposed between the outJ,ets at the street, and the culverts under the berm- The culverts are required under the berm because the berm is used as an access road to otherwise landlocked property, and for maintenance of the canal, Ympacts to Zone 1 of the riparian buffer will be minimal because this area is already cleared and is being mnaintained as au access road- The Zone2 area -will be revegetated with grass after constructionx. The total disturbance to the wetland areas will be limited to appro).mately 0.10 acres. No =tigation is proposed for the buffer or wetland impacts because the wetlands impacts are less than, 1/3 acre, and the riparian bier is already disturbed with an'access road The disturbance of the buffer and wetlands is required due to chaimelization ofMoccasin. Creek and subsequent berm construction, which created a hardship on the property owner. 09/24/03 12:55 FAX 919 773 0148 SOUTHWIND SURVEYING Filter Strip Calculations Filter Strip design requirements are taken from the Johnston Counter Stormwater Design Manua]. Once properly constructed, periodic inspections will be made to insure that all gullies and eroded areas are repaired and that the grass is being maintained at the correct height to facilitate function of the strip. Site # 1 Requirement 1: Velocity entering the filter strip may not exceed 1 fps during the l 0-Year Storm Flow enters the filter strip through a RC pipe accepting stornrwater flow from the proposed Street_ Use the Rational Method to calculate the flow during the I0-Year Storm.

Use the Normal Depth Procedure (description attached), an iterative process based on Manning's Equation, to calculate the depth of flow at a given ditch cross section. The depth of flow is used to calculate the cross-sectional area of flow, which is then used to calculate the velocity of flow entering the filter strip. Iterations show that the velocity of flow is equal to approximately 1 fps when the bottom width of the ditch is 5 feet. Once the velocity is slowed through this initial outlet ditch section of 5 foot bottom width, the outlet ditch transitions into a filter strip of dimensions as indicated Requirement 2- The bottom width of the filter strip is determined by the width of flow in the 2-Year Storm at a flow depth of 0.5 feet.

The DWQ has determined that your application was incomplete and/or provided inaccurate information as discussed below. The DWQ.will require additional information in order to process your application to impact protected wetland, streams and/or buffers on the subject property. Therefore, unless we receive the additional information requested below, we will have to move toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8) and will place this project on hold as incomplete until we receive this additional information. Please provide the following information so that we may continue to review your project. Additional Information: It is not clear in your plans how you intend to comply with the diffuse flow requirement of the Neuse Buffer Rule [15A NCAC 02B .0233(5)]. 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, the DWQ requires that a stormwater management plan for this project be submitted in order to complete the review of your application. 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. Please contact Mr. Todd St. John of the DWQ Wetlands/401 Unit at (919) 733-9584 if you have any questions or would like to set up a meeting regarding this matter. Please respond within three weeks of the date of this letter by sending this information to me in writing and Mr. Steve Mitchell of the DWQ Raleigh Regional Office. If we do not hear from you within three weeks, we will assume that you no longer want to pursue this project and we will consider the project as withdrawn.

Page 7 of 7 VIII. Mitigation D WQ - 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 USAGE 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.ne.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/linea.r 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.

The property is bounded on the west side by Moccasin Creek canal. Moccasin Creek was channelized approximately 25 years ago to help alleviate flooding problems in the Selma area. The spoil material from the channelization was placed on the east side of the creek, which created a berm along the west side of the subject property. No drainage pipes were installed in the berm to allow the adjacent property to drain. This damming effect created the wetland area that now exists on the property. Prior to channelization of Moccasin Creek, the subject property naturally drained to Moccasin Creek. Proposed Ymnacts The proposed impacts to the wetlands and riparian buffer consist of construction of grass lined swales and storm drain pipes perpendicular to Moccasin Creek, to convey stormwater from the proposed residential development to the creek. To minimize impacts, only two stormwater outlets are proposed. The stormwater outlets are necessary to prevent flooding of the homes within the proposed development. No streets or other improvements are proposed within the wetland or riparian buffer areas. Justification/Minimization The existing berm along Moccasin Creek does not allow for converting concentrated flow to sheet flow before entering the buffer. The Town of Selma will take over maintenance of the stormwater facilities after construction. They desire that the stormwater be piped all the way to the creek for maintenance purposes. The developer would also prefer this to avoid additional standing water, which will attract mosquitoes and provide a negative appearance. However, to provide treatment of the stormwater before entering the creek, vegetated filter strips are proposed between the outlets at the street, and the culverts under the berm. The culverts are required under the berm because the berm is used as an access road to otherwise landlocked property, and for maintenance of the canal. Impacts to Zone 1 of the riparian buffer will be minimal because this area is already cleared and is being maintained as an access road. The Zone2 area will be revegetated with grass after construction. The total disturbance to the wetland areas will be limited to approximately 0.10 acres. No mitigation is proposed for the buffer or wetland impacts because the wetlands impacts are less than 1/3 acre, and the riparian buffer is already disturbed with an access road. The disturbance of the buffer and wetlands is required due to channelization of Moccasin Creek and subsequent berm construction, which created a hardship on the property owner. 35'v-3-3:5 J . ` f ! j i, - _ r c ? : Bern, ? `Yll ? x =7 --- - ve Pit a • @b 'Moccasin Creek Canal Ba eaf Pointe Sub di, ision N3 2 [ea y ' • 195 C i?•--? l ,i ^tf"..

SEE Ai4r V., A, C. N -C I+. Page 7 of 7 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 fiznctions 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/Stnngide.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.

The property is bounded on the west side by Moccasin Creek canal. Moccasin Creek was channelized approximately 25 years ago to help alleviate flooding problems in the Selma area. The spoil material from the channelization was placed on the east side of the creek, which created a berm along the west side of the subject property. No drainage pipes were installed in the berm to allow the adjacent property to drain. This damming effect created the wetland area that now exists on the property. Prior to channelization of Moccasin Creek, the subject property naturally drained to Moccasin Creek. Proposed Impacts The proposed impacts to the wetlands and riparian buffer consist of construction of grass lined swales and storm drain pipes perpendicular to Moccasin Creek, to convey stormwater from the proposed residential development to the creek. To minimize impacts, only two stormwater outlets are proposed. The stormwater outlets are necessary to prevent flooding of the homes within the proposed development. No streets or other improvements are proposed within the wetland or riparian buffer areas. Justification/Minimization The existing berm along Moccasin Creek does not allow for converting concentrated flow to sheet flow before entering the buffer. The Town of Selma will take over maintenance of the stormwater facilities after construction. They desire that the stormwater be piped all the way to the creek for maintenance purposes. The developer would also prefer this to avoid additional standing water, which will attract mosquitoes and provide a negative appearance. However, to provide treatment of the stormwater before entering the creek, vegetated filter strips are proposed between the outlets at the street, and the culverts under the berm. The culverts are required under the berm because the berm is used as an access road to otherwise landlocked property, and for maintenance of the canal. Impacts to Zone 1 of the riparian buffer will be minimal because this area is already cleared and is being maintained as an access road. The Zone2 area will be revegetated with grass after construction. The total disturbance to the wetland areas will be limited to approximately 0.10 acres. No mitigation is proposed for the buffer or wetland impacts because the wetlands impacts are less than 1/3 acre, and the riparian buffer is already disturbed with an access road. The disturbance of the buffer and wetlands is required due to channelization of Moccasin Creek and subsequent berm construction, which created a hardship on the property owner. N.
