The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual. b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 3. Protective Fencing The outside wetland or water boundary and along the construction corridor within these boundaries approved under this authorization shall be clearly marked with orange warning fencing (or similar high visibility material) for the areas that have been approved to infringe within the wetland or water prior to any land disturbing activities to ensure compliance with 15A NCAC 2B .0233. Swann's Mill Subdivision Page 3 of 5 August 31, 2005 4. Diffuse Flow (DWQ Reviewed Plans) All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream buffers and will not re-concentrate before discharging into the stream as identified within 15A NCAC 2B.0233(5) In an effort to comply with the diffuse flow provision of the Buffer Rule [15A NCAC 02B .0233(5)], you have provided the DWQ with plunge pool and level spreader designs dated May 12, 2005. The DWQ believes that if implemented, as per these plans, diffuse flow will be achieved. However, if diffuse flow as per 15A NCAC 02B.0233(5) is not achieved, then the DWQ shall be notified and corrective actions to restore diffuse flow shall be taken if necessary to impede the formation of erosion gullies. At no time shall stormwater from the proposed development be piped directly through the buffer without prior DWQ written authorization. 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. Stormwater easements shall be recorded for a distance of at least 10 feet on each side of all stormwater conveyances and on all lots containing these structures including future access for maintenance. The stormwater easements shall allow for the ability to maintain the structures, perform corrective actions as described above and shall provide protection of the structures from potential alternations by future property owners. 5. Construction Stormwater Permit NCGO10000 Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically issued to the project. This General Permit allows stormwater to be discharged during land disturbing construction activities as stipulated by conditions in the permit. If your project is covered by this permit [applicable to construction projects that disturb one (1) or more acres], full compliance with permit conditions including the sedimentation control plan, self-monitoring, record keeping and reporting requirements are required. A copy of this permit and monitoring report forms may be found at http://h2o.enr.state.nc.uslsulForncs Documents.hbn. 6. No Waste, Spoil, Solids, or Fill of Any Kind No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Pre-Construction Notification. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. Swann's Mill Subdivision Page 4 of 5 August 31, 2005 7. No Sediment & Erosion Control Measures w/n Wetlands or Waters Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the date that the Division of Land Resources has released the project. 8. No Impacts to Zone 1 No impacts shall occur to Zone 1 of the protected riparian buffers (except for uses and activities designated as "exempt" within 15A NCAC 02B .0233), unless otherwise approved by DWQ. 9. Culvert Installation The bottomless culverts, bottomless arches or other spanning structures used on this project shall span the entire bed and both banks of the stream and may only be used for a road, driveway or path crossing. Mitering of the bottomless culvert in order to follow the stream pattern is prohibited. The bottomless 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) must be maintained above and below locations of each culvert. Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent head cutting of the streams. 10. 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. 11.

Prior Project History If jurisdictional determinations and/or permits have been requested and/or obtained for this project (including all prior phases of the same subdivision) in the past, please explain. Include the USACE Action ID Number, DWQ Project Number, application date, and date permits and certifications were issued or withdrawn. 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. An On-site Determination for the presence of surface waters subject to the Neuse Buffer Rule was conducted by Ms. Deborah Edwards of the N.C. DWQ in February 2002 (DWQ Project No. NBRRO 02-046: see attached letter). A Jurisdictional Determination for the presence of Waters of the US regulated under Section 404 of the Clean Water Act was conducted by the USACE in May 2002 (Action ID No. 200220561; see attached letter). Approval to use NWP 12 was issued by the USACE in January 2004 for the construction of a sanitary sewer line to serve the development Action ID No. 20022056ia. A PCN was submitted to the USACE and DWQ including additional information between April and July 2005. The latest on hold letter from the DWQ was dated July 25, 2005. The applicant has decided to use arch culverts to avoid stream impacts associated with Miller Drive and has withdrawn their original application and has requested an Express Review - Authorization Certificate for the proposed buffer impacts designated as "allowable" within the Neuse Buffer Rule (see attached Express Review Acceptance Letter dated August 3, 2005 Page 3 of 11 The applicant has minimized impacts to wetlands and waters to less than \1/10\ acre. The applicant understands that notification to the DWQ is not required to use General Water Quality Certification No. 3402 because the impacts to wetlands and waters will be less than \1/10\ acre and the project will comply with all of the other conditions of GC3402. The impacts that total less than 1/10 of an acre include 0.03 acres of wetland impacts associated with the construction of Cozart Street, 0.02 acres of linear wetland impacts associated with construction and fill of lots 119 to 123, and 0.005 acres of temporary stream channel impacts associated with the construction of a sanitary sewer line under Miller Drive as described below. The total impacts to wetland and waters associated with this project will therefore equal 0.055 acre (less than \1/10\ acre . A sanitary sewer line is proposed within the footprint of the northern stream crossing of Miller Drive (Stream Crossing #2). The sewer line will avoid additional buffer impacts by crossing this stream within the same footprint of the road crossing. We believe that the temporarY stream impacts associated with this sewer crossing should be classified as an "exempt" activity within the Neuse Buffer Rule as a "Non-electric utility line ine perpendicular crossings of surface waters ... that disturb equal to 40 linear feet of riparian buffer with a maintenance corridor equal to or less than 10 feet in width". Because this activity is classified as "exempt" under the Neuse Buffer Rule, we believe that the stream impacts should not trigger notification under Condition No. 2 of GC3402. As such, the applicant intends to use GC3402 for these impacts and will comply with all of the conditions of GC3402. The USACE will be sent a separate, courtesy copy PCN application notifying, them of the temporary stream impacts associated with the sewer line. We do not believe that these tempora impacts will require formal notification to and approval from them in that they are temporary and will not result in the loss of stream channel as defined under Condition No. 2 of NWP39. A report will be sent to the USACE notifying them that less than \1/10\ acre of impacts to wetlands and waters has occurred within 30 days after completion of the work as required under Condition I of NWP39. V. Future Project Plans Are any future permit requests anticipated for this project? If so, describe the anticipated work, and provide justification for the exclusion of this work from the current application. The applicant does not anticipate any future impacts to wetlands, streams or buffers on the property. A potential off site water line crossing of a stream may be required. However, the applicant anticipates using directional drilling methods to avoid impacts to the stream and buffers and as such no approvals should be required for this crossing. The water line will service other adjacent properties as well as Swann's Mill. Page 4 of 11 VI. Proposed Impacts to Waters of the United States/Waters of the State It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to wetlands, open water, and stream channels associated with the project. Each impact must be listed separately in the tables below (e.g., culvert installation should be listed separately from riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts, permanent and temporary, must be listed, and must be labeled and clearly identifiable on an accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial) should be shown on a delineation map, whether or not impacts are proposed to these systems. Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. 1. Provide a written description of the proposed impacts: Arch culverts are proposed to avoid all stream impacts associated with the development. There is _a _total of approximately 0.055 acre of wetlands and waters proposed to be impacted by the development associated with lot and road fill and tempora , utility impacts. The applicant is proposing to use NWP 39 and GC 3402 to conduct these activities as described within Section IV of this application. The applicant understands that these impacts do not require notification to or prior written authorization from the USACE or DWO because the total proposed impacts are less than \1/10\ acre and because there are no permanent stream impacts proposed and the proposed temporary stream impacts are classified as "exempt" under the Neuse Buffer Rule. 2. Individually list wetland impacts.

Isolated Waters Do any isolated waters exist on the property? ? Yes ® No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. Page 6 of I I 8. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ? uplands ? stream ? wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. During the initial design phases of the development, the applicant hired S&EC to locate all wetlands. streams and buffers on the property to revise their site plan to avoid or minimize impacts to these resources. The two tributary stream drainages located on the property rain predominately from the east to the west. The site plan was developed to minimize the amount of interior, north/south subdivision roads that would require crossing these tributary drainages. The current site plan proposes only one north/south road (Miller Drive) that would cross these two drainages. The developer has further minimized impacts to these drainages by using arch culverts to avoid stream 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 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 January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable Page 7 of 11 mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.ne.us/ncwetiands/strmgide.htmi. 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 ofl:site), 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. Mitigation should not be required for the proposed impacts because stream impacts have been avoided, wetland impacts have been minimized to below 1/10 acre, and buffer impacts are less than 1/3 acre and 150 feet for each crossing. If mitigation is determined to be required, then the applicant proposes payment to the Ecosystem Enhancement Program. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): Amount of buffer mitigation requested (square feet): Amount of Riparian wetland mitigation requested (acres): Amount of Non-riparian wetland mitigation requested (acres): Amount of Coastal wetland mitigation requested (acres): IX. Environmental Documentation (required by DWQ) 1. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ? No Page 8 of 11 2. 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 ? 3. If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ? No ? X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. 1. Will the project impact protected riparian buffers identified within 15A NCAC 213 .0233 (Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify V Yes ® No ? 2. If "yes", 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. STREAM CROSSING #1 Required Zone* (square Impact Multiplier Mitii tion 1 5,663 3 (2 for Catawba) 0 2 3,485 1.5 0 Total 9,148 0 * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. STREAM CROSSING #2 Zone* ( Hare feet) Multiplier Required 1 4,356 3 (2 for Catawba) 0 2 4,792 1.5 0 Total 9,148 0 * Zone 1 extends out 30 fat perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone 1. NOTE: When revic,. ing the impact maps, please note that the buffers depict both the 50-foot Neuse River Buffer as well as the additional 10 foot Durham County buffer building set back. Page 9 of 11 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0244, or.0260. The proposed crossings are each less than 1/3 acre and 150 feet of buffer impacts and as such should be considered "allowable" without mitigation. XI. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. The applicant understands that a written stormwater management plan will not be required for the development as outlined within Condition No. 4 of GC3402, because notification and written authorization is not required to use this Certification. It should be noted that this development is located within a WS-IV watershed and will comply with the City of Durham water supply ordinances and the overall development will be less than 24% built upon area as defined under the City's ordinance. The development will comply with the diffuse flow requirements of the Neuse Buffer Rule through the use of level spreaders. Level spreader detail design plans and worksheets are provided. The level spreader design intends to use an alternative design of the bypass option described within the current DWQ Draft Level Spreader Design Options document (see attached). This alternative design is required because of the size and imperviousness of the drainage area and other site constraints that prevent conventional level spreader designs. The project engineer believes that these designs will allow for the level spreaders to function properly by bypassing the larger discharge events. The design while developed by the project engineer is almost identical to a design in use by the Montgomery County, Maryland, Department of Permitting Services, Water Resources Section to help protect the Chesapeake Bay watershed (see attached documentation. The larger, bypassed storm flows will be discharge to properly sized rock dissipaters within the virtually flat flood plain. greater than 250 feet from the stream. XII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. The development will connect to the existing City of Durham sanitary sewer system. The City will ensure that this connection does not exceed the available capacity of their treatment facility. Page 10 of 11 XM. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules? Yes ? No Is this an after-the-fact permit application? Yes ? No XIV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ? No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetIands. If no, please provide a short narrative description: The proposed residential development will provide housing to meet existing demands and is not anticipated to result in or act as a catalyst for additional development. XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits. However, an applicant may choose to list constraints associated with construction or sequencing that may impose limits on work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and Threatened Species, accessibility problems, or other issues outside of the applicant's control). re Date (Agent's signature is valid only if an authorization letter from the applicant is provided.)

Basis for Determination: The site contains wetlands and stream channels with indicators of ordinary high water marks, located adjacent to an unnamed tributary of the Eno River, above headwaters, in the Neuse River Basin. Indicate Which of the Following Apply: X There are waters of the U.S., to include wetlands, on the above described property which we strongly suggest should be surveyed. The surveyed wetland lines must be verified by our staff before the Corps will make a final jurisdictional determination on your property. Because of the size of your property and our present workload, our identification and delineation of your wetlands cannot be accomplished in a timely manner. You may wish to obtain a consultant to obtain a more timely delineation of the wetlands. Once the consultant has flagged a wetland line on the property, Corps staff will review it, and, if it is accurate, we strongly recommend that you have the line surveyed for final approval by the Corps. The Corps will not make a final jurisdictional determination on your property without an approved survey. X The waters of the U.S., to include wetlands, on your lot have been delineated, and the limits of the Corps jurisdiction have been explained to you. Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. There are no waters of the U.S., to include wetlands, present on the above described property which are subject to the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law or our published regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification. Placement of dredged or fill material in wetlands on this property without a Department of the Army Permit is in most cases a violation of Section 301 of the Clean Water Act (33 USC 1311).

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 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 Requested: 1. There appear to be discrepancies between the impervious surface area breakdown submitted and what DWQ has calculated. You are reminded that it is DWQ policy that even when a phased development is below the threshold for engineered stormwater controls, areas of concentrated development that meet the threshold must have runoff treated through engineered controls. Please recalculate the impervious surface areas. 2. Your project lies within the critical area of Water Supply IV (WS-IV). You are reminded of the requirements for nonpoint sources and stormwater pollution [ 15A NCAC 02B .0216(3)(b)(ii)] for the low density vs. high-density option. That is, if you exceed 24% built upon area, then engineered stormwater controls shall be used to control runoff from the first 1" of rainfall; new residential and non-residential development shall not exceed 50% built- upon area. 401 Oversight/Express Review Permits Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919-733-1786 /FAX 919-733-6893 / Internet: htto://h2o.enr.state,nc.us/ncvvetlands Npv Carolina Natimally An Equal Opportunity/Affirmative Action Employer- 50% Recycled/10% Post Consumer Paper D. R. Horton Page 2 of 2 July 25, 2005 3. Condition 4 of GC 3402 requires the use of constructed wetlands or bio-retention (or wet ponds followed by engineered forested filter strips) in watersheds classified as WS. Additionally, your project must meet the diffuse flow requirements of the riparian area protection rules (Buffer Rules). Level spreaders must be designed in accordance with DWQ guidance. All stormwater management facilities require a signed and notarized Operations and Maintenance Agreement. Please resubmit a complete stormwater management plan with drainage maps, site plan with the location of the stormwater control devices, DWQ stormwater BMP worksheets, and supporting calculations. 4. This office believes that reconfiguration of your plan can avoid some of the impacts. Please respond within three weeks of the date of this letter by sending three (3) copies of this information in writing. 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. This letter only addresses the application review and does not authorize any impacts to wetlands, waters or protected buffers. Please be aware that any impacts requested within your application are not authorized (at this time) by the DWQ. Please call Cyndi Karoly at 919-733-9721 or Samuel A. Aghimien at 919-733-3574 if you have any questions regarding these issues.

MONTGOMERY COUNTY MARYLAND DEPARTMENT OF PERMITTING SERVICES WATER RESOURCES SECTION FLOW SPLITTING DESIGN CRITERIA Revised January 2005 "Flow splitting" is used for diverting a quantity of water from a larger flow volume. Flour splitting is commonly used to separate the water quality volume (WQV) from larger flows. The objective is to isolate the WQV as much as possible from the diluting and mixing effects of larger flows. Isolation increases the efficiency of the pollutant removal mechanisms of the water quality treatment. Separation is accomplished through these guidelines as follows: A. Typical Methods of Flow Splitting 1. Surface Flow Splltters A typical rip-rap storm drain outfall drains to an open, shallow, concrete wall containment area, which has a low-flow orifice set in one wall at the bottom elevation. This orifice delivers the treatment volume to the water quality treatment facility. Once that volume/flow has been delivered, larger flows then overtop a weir set in another wall to flow to the quantity control facility or to a safe outfall system. This may also be accomplished through the use of a yard inlet, which overflows into a designed swale in large storm events. 2. Underground Storm Drain Structure Splltters At the lowest invert of a typical storm drain structure, a low flow pipe is placed to deliver the treatment volume to the water quality treatment facility. Once that volume/flow has been delivered, larger flows exit the structure through a typical outgoing 10-year storm drain pipe to flow a safe, non-erosive outfall. 3. Integral Flow Splitters The above technique can easily be adapted to underground quality treatment structures by adding an additional chamber to provide for diversion of flow. Splitter Weir A weir is constructed in the bottom of a storm drain facility, often an inlet, to divert flows to a low flow pipe. The weir is sized to divert the required WQV. B. Flow Splitting Design There are two general methods used to achieve flow splitting: Storage Method and Flow Restriction Method. Storage Mothod The preferred, easiest, and most effective method to design a flow splitter is with the "storage" method. This method uses the chosen treatment storage volume (the WQV) as the key to the system. The treatment volume is delivered to the quality facility. The facility is sized to store this design volume. The water surface elevation of that treatment volume is then used to set the elevation of the controlling overflow weir or pipe in the flow splitter structure. The delivery opening to the quality facility must be checked to ensure it is non-restrictive, but will not allow too much flow to enter the facility. This is accomplished via item "2" below. The diameter of the flow split delivery pipe should be one standard size larger than the size required for the restricted flow method. 1t4#gRY1,VD I-Nro, With this method of flow splitting, the embankment must be designed to provide a minimum of 1 foot of freeboard above the 10-year WSEL within the facility. Overflows occur through the flow splitter structure ... no overflow weir or other structure is allowed in the facility embankment. If the freeboard can not be achieved and an overflow structure is required in the embankment, then the `flow restriction" method must be used. 2. Flow Restriction Method If site constraints preclude the storage method from working, then the flow splitter can be designed with the "flow restriction method. This is a less preferred method. With this method computations are supplied to demonstrate that the treatment volume delivery opening is restrictive to peak flows (Q's) greater than that produced by the WQV. Usage of this method requires a structural overflow weir or riser in the water quality facility to pass the flow produced by larger storms. Grassed weirs are not acceptable. To follow this method, determine the peak treatment discharge (Q) as outlined in Appendix D.10 of the 2000 Maryland Stormwater Design Manual. Utilizing the Q calculated above, determine either the pipe or orifice size that will convey pEly the required flow via the orifice flow equation. The head on the pipe should be taken from the centerline of the first flush pipe to the invert of the overflow pipe. C. Matorials/Pipe Criteria Flow splitting pipes typically range in size between 6 - 12 inches; however, larger pipes may also be used. The minimum pipe size allowed is 6 inches. When splitting from a publicly maintained manhole, a maximum distance of 12 inches is allowed between the invert of the 10-year outgoing storm drainpipe and the crown of the first flush pipe. Weirs are not allowed in public structures. D. Trash Rack Criteria Trash racks must be designed to be self flushing whenever possible. Refer to the Montgomery County detail entitled Diversion Structure Manhole Detail. All flow split delivery openings or pipes smaller than 15 inches in diameter require trash racks. If the flow split delivery opening or pipe is 15 inches or larger in diameter, a trash rack is not required. Trash racks may be either expanded metal or rebar. All trash racks must be removable. E. Construction Notes on Plans It is extremely important that flow-splitters be built correctly. Please insure the detailed plans reflect the following: The Sequence of Construction must specifically identify the flow splitter by structure number. Add the actual dimension between the invert of the flow splitter pipe and the invert of the overflow pipe to the detail on the plans. 3. Add a note to the detail calling for 'the contractor to verify that dimension prior to backfilling around the structure, and to notify the design engineer immediately if there is a discrepancy.'

Stevens Division of Water Quality Draft Level Spreader Design Options Version 1.0 October 10, 2001 Using Level Spreaders to Provide Diffuse Flow Through Buffers for Compliance with Riparian Area Protection Rules Level spreaders are one means of providing diffuse flow through protected buffers. It is always preferable to not concentrate stormwater initially and provide as many outfalls as possible. This can reduce or even eliminate the need for engineered devices to provide diffuse flow. However, this is not feasible in many cases. Some buffer protection rules such as the Neuse, Catawba, and Tar-Pamlico Riparian Area Protection Rules do not allow direct discharges of stormwater through the protected buffers. However, it is 'allowable' with written approval from the DWQ to provide best management practices (BMPs) that remove the nutrients or pollutants in question in order to discharge directly through the buffer. These measures could include the use of the buffer itself as a forested filter strip, for instance, to remove the desired substances. In addition to providing diffuse flow, level spreaders can be used to distribute flow into filter strips. There are certain criteria that apply to every design that utilizes level spreaders to provide diffuse flow. 1) The entire system must safely pass a 10 year storm event without failing or causing erosion, gullies or rills. 2) The design of the level spreader must take into consideration site specific conditions such as topography, vegetative cover, soil and other geologic conditions. If diffused flow is not attainable based on site conditions they should not be used. (i.e. the slope of the natural ground away from or parallel to the level spreader should be relatively smooth in the direction toward the stream so that the flow will not reconcentrate.) 3) Level spreaders should have a minimum length of ten feet and an absolute, maximum length of 300 feet. 4) It is always easier to keep flow distributed than to redistribute it after collection. 5) The type and amount of vegetative ground cover must also be considered. 6) Level spreaders must be level. Level Spreader Design Options: Conventional level spreader design option where entire discharge is passed through the level spreader with no bypass conveyance for larger storms: • For grass or thick ground cover vegetation: i)13 feet of level spreader for every 1 cfs flow (Based on Q10 discharge) ii) maximum length of 300 feet per level spreader iii) Slopes of 8% or less from level spreader to top of stream bank • For forested areas with little or no ground cover vegetation: i) 100 feet of level spreader for every 1 cfs flow (Based on Q10 discharge) ii) maximum length of 300 feet per level spreader iii) slopes of 6% or less from level spreader to top of stream bank Another conventional level spreader design technique that can be used to accommodate steeper slopes where grading is allowed or exempt in zone 2 of protected buffers is to provide level spreaders in series as follows: • Can be used on slopes of up to 15% for forested areas and 25% for grass or thick ground cover • Structural level spreader just outside of zone 2 followed by a grassed berm level spreader just outside of zone 1 North Carolina Division of Water Quality, 401 Wetlands Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650 (Mailing Address) 2321 Crabtree Blvd., Raleigh, NC 276042260 (Location) 919-733-1786 (phone), 919-733-6893 (fax), http://h2o.enr.state.ne.us/ncvetlands/ Page 2 of 2 • Maximum Q10 discharge of 1 cfs per 100 feet of level spreader for forested areas and 1 cfs per 13 feet of level spreader for grass or thick ground cover In some instances, because of topography, the size and imperviousness of the drainage area, or other site constraints, conventional level spreader designs are not appropriate. However, there are alternative designs, like the ones listed below, that would allow a level spreader to function properly by bypassing the larger discharge events. This is based on the assumption used in designing most water quality BMPs that the 'first flush' of stormwater discharge contains the most substances of concern. These other alternatives are *allowable (require written approval from DWQ)' for protected buffers in the Neuse, Tar-Pamlico and Catawba basins, but would not be allowable in protected buffers of the Randleman watershed. Level spreader with bypass for larger drainage areas that require 85% TSS removal or where lateral constraints limit the level spreader length severely: • Dry detention basin designed per NCDENR Stormwater BMP Manual" sized to detain 1" rain and release it over 2-5 days' through a level spreader. • Level spreader length based on the maximum release rate discharge • Discharges from greater than a 1' rain can be bypassed via an appropriate conveyance such as a grassed swale (rip rap lined ditch or pipe may be used if necessary) • Maximum discharge of 1 cfs per 100 feet of level spreader for forested areas and 1 cfs per 13 feet of level spreader for grass or thick ground cover in order to meet 85% TSS Removal criteria) Another bypass alternative can be used that would not be considered to remove 85% TSS: • Detention basin such as a type B silt basin preceding the level spreader • Level spreader length based on the 1" per hour intensity storm • A system designed to bypass the greater than 1" in per hour intensity storm through an appropriate conveyance such as a grassed swale (rip rap lined ditch or pipe may be used if necessary) • Maximum discharge of 1 cfs per 100 feet of level spreader for forested areas and 1 cfs per 13 feet of level spreader for grass or thick ground cover Yet another design that can be used in very specific areas with virtually flat slopes is a Preformed Scour Hole with a Level Spreader Apron (typical detail attached): • Discharge area must have virtually flat slopes such as those in flood plains or wetlands • Must be located outside of zone 2 • B = 3 x discharge pipe size for pipes of either 15 or 18 inches B= base width (see detail) • Maximum allowable discharge (Q10) of 6 cfs for a 15 inch pipe and 10 cfs for an 18 inch pipe • Minimum apron width of 4 feet. Any of the above options will be considered acceptable if designed in accordance with the outlined criteria. Please keep in mind that some of the above practices may still require written approval, for instance when a direct bypass discharge is proposed through a protected buffer in the Neuse or Tar-Pamlico River Basin. ?CF W ATF9Q Michael F.
