Dominant vegetation within the project area consists of willow oak (Okras hellos ), water oak (Okras nigra ), box elder (Aer negundo ), common blackberry (Rubus argutus), poison ivy (iFiDdendron radians ), English ivy (Mera helix ), and fescue (Fstua sp.) NORTH CAROLINA - SOUTH CAROLINA WWW.CWS-INC.NET Shillington CIP August 5, 2010 Nationwide Permit No. 3 and 27 Proiect No. 2010-2718 According to the Soil Survey of Mecklenburg County' (Figure 2. NRCS Soil Survey Map, attached), on-site soils consist of Cecil sandy clay loam, 2 to 8 percent slopes, eroded (CeB2), Cecil sandy clay loam, 8 to 15 percent slopes, eroded (CeD2), Iredell fine sandy loam, 1 to 8 percent slopes (IrB), Iredell-Urban land complex, 0 to 8 percent slopes (IuB), Mecklenburg fine sandy loam, 2 to 8 percent slopes (MeB), Mecklenburg fine sandy loam, 8 to 15 percent slopes (MeD), Monacan loam (MO), Wilkes loam, 4 to 8 percent slopes (WkB), Wilkes loam, 8 to 15 percent slopes (WkD), and Wilkes- Urban land complex, 8 to 15 percent slopes (WuD). Cecil, Mecklenburg, and Wilkes soils are well drained. Iredell soils are moderately well drained. Monacan soils are somewhat poorly drained and are listed in the North Carolina Hydric Soils List for Mecklenburg County as having hydric inclusions2. Monacan soils are also listed as hydric soils (hydric criteria 2B3, 4) on the National Hydric Soils Lists. Jurisdictional Determination On July 12, 2010, CWS's Thomas Blackwell and Sarah Singleton delineated on-site jurisdictional waters of the U.S. using the U.S. Army Corps of Engineers (USACE) - Routine On-Site Determination Method. This method is defined in the 1987 Corps of Engineers Wetlands Delineation Manual.4 A Routine On-Site Data Form representative of non jurisdictional upland areas has been enclosed (DPI). Jurisdictional stream channels were classified according to recent USACE and North Carolina Division of Water Quality (NCDWQ)5 guidance. These classifications included sampling with a D- shaped dip net, taking photographs, and defining approximate breakpoints (location at which a channel changes classification) within each on-site stream channel. NCDWQ Stream Classification Forms and USACE Stream Quality Assessment Worksheets representative of Stream A are enclosed (SCP1 - SCP2). The results of the on-site field investigation indicate that there is one jurisdictional stream channel (Stream A), and one jurisdictional open water area (Pond A), located within the project area (Figure 3, attached). Stream A is an unnamed tributary to McMullen Creek. McMullen Creek is within the Catawba River basin (HU# 03050103)6 and is classified as "Class C" waters by the NCDWQ. On-Site jurisdictional waters are summarized in Table 1., below. ' United States Department of Agriculture, 1971.

Stream A has been extensively piped. The lower 1,549 linear feet of Stream A was determined to be perennial. Perennial Stream A exhibited a strong bed and bank, weak sinuosity, strong in-channel structure, substrate consisting of coarse sand, gravel and cobbles, moderate flow, and an average ordinary high water width of eight feet. Biological sampling revealed a weak presence of fish and amphibians. Stream characteristics indicate that flow is present year round. Therefore, this portion of Stream A was classified as a relatively permanent water (RPW) with perennial flow according to USACE/EPA guidance. Perennial RPW Stream A scored 64 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 32.5 out of a possible 63 points on the NCDWQ Stream Classification Form (SCP1, enclosed). Photographs A and B (enclosed) are representative of Perennial RPW Stream A Intermittent Streams The upper 409 linear feet of Stream A was determined to be intermittent. Intermittent Stream A exhibited a strong bed and bank, weak sinuosity, moderate in-channel structure, substrate consisting of coarse sand and fine gravel, and an average ordinary high water width of six feet. Stream characteristics indicate that continuous flow is present for at least three months in an average year. Therefore, this portion of Stream A was classified as a relatively permanent water with seasonal flow (Seasonal RPW) according to USACE/EPA guidance. Seasonal RPW Stream A scored 43 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 26.5 out of a possible 63 points on the NCDWQ Stream Classification Form (SCP1, enclosed). Photographs C and D (enclosed) are representative of Seasonal RPW Stream A Open Waters Pond A is approximately 0.76 acre in extent and is an impoundment of Intermittent RPW Stream A. Photograph E (enclosed) is representative of Pond A. 3 Shillington CIP August 5, 2010 Nationwide Permit No. 3 and 27 Proiect No. 2010-2718 Agency Correspondence Cultural Resources A letter was forwarded to the State Historic Preservation Office (SHPO) on July 8, 2010 to determine the presence of any areas of architectural, historic, or archaeological significance that would be affected by the project. In a response letter dated July 28, 2010 (attached), the SHPO stated that they "are aware of no historic resources which would be affected by the project." CWS consulted the Charlotte Mecklenburg Historic Landmarks Commission database and found no listed properties within the project area. Protected Species A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on July 8, 2010 to determine the presence of any federally-listed, candidate endangered, threatened species or critical habitat located within the project area. In a response letter date July 15, 2010 (attached), the NCNHP stated that "The Natural Heritage Program has no record of rare species, significant natural communities, significant natural heritage areas, or conservation/managed areas at the site nor within a mile of the project area." In addition, the NCNHP Geographic Information Systems (GIS) database Virtual Workroom and Element Occurrence (EO) database was reviewed for a listing of EOs of endangered or threatened species within or near the project area. The EO database identified no endangered or threatened species within a two-mile radius of the project area. Purpose and Need for the Project Flooding and erosion problems within the project area have been reported by neighborhood residents and are documented in formal responses to City questionnaires and service requests. The channel upstream of Bar Harbor lane is severely eroded. The banks on the northwest side are encroaching on the property owners decorative iron fence and tree roots are continuing to be exposed (potential loss of trees into the channel). The channel bottom continues to erode and several locations of bedrock have appeared. Photographs C and D (enclosed) illustrate the existing condition of this channel. There is also a section of bank instability at 8443 Eagle Glen Way. The stream bank is eroding at this point and is threatening trees and the air-conditioning units for the residence at that site. Photograph F shows the erosion at this location. The purpose of this project is to reduce flooding, dissipate high velocity storm flows at outfalls, and reduce storm-induced erosion downstream of culverts. In addition, the project will enhance the stream channel upstream of Bar Harbor Lane and at 8443 Eagle Glen Way. This overall project will involve the replacement of existing culverts, replacement of existing rip rap aprons, and stream enhancement. Stream A upstream of Bar Harbor Lane will be enhanced with the use of vegetated geogrids on the banks to provide improved bank stability (Plan Sheet 14A, attached). This will result in reducing the sediment input to the stream. Vertical stability will be provided through the use of cross-vanes. Vegetated geogrids are proposed due to the limited space available. Laying back the channel banks and providing benching is not possible due to the encroachment on structures and fences, and the loss of tree canopy over the stream which would result. Rip rap aprons will be installed at culvert outlets (Plan Sheets 4, 4A, 9, and 14A, attached). Where possible these aprons will be limited to the stream banks. 4 Shillington CIP August 5, 2010 Nationwide Permit No. 3 and 27 Protect No. 2010-2718 Avoidance and Minimization Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable. Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. All work will be constructed in the dry in accordance with Water Quality Certification No. 3687. Impacts to the bed of existing channels have been avoided wherever possible, and there will be no loss of jurisdictional waters. Furthermore, the project includes 250 linear feet of stream enhancement. This enhancement work will stabilize currently eroding stream channel and will result in a reduction in sediment input to the stream and a net improvement in stream quality. A new bypass pipe will be installed between Bar Harbor Lane and Shillington Place (Plan Sheets 13 & 14, attached) to eliminate flooding at this location. This pipe will carry flow from Intermittent Stream A (upstream of Bar Harbor Lane) and will tie into the existing Shillington Place culvert. The existing pipes and open stream channel between Shillington Place and Bar Harbor Lane will remain in-situ. No fill or piping of Perennial Stream A will occur and there will therefore be no impact to Jurisdictional Waters of the U.S. Proposed Impacts to Jurisdictional Waters Unavoidable impacts to Jurisdictional Waters of the U.S. total 350 linear, feet of stream impacts. These impacts include 100 linear feet of permanent impacts and 250 linear feet of temporary impacts (Figure 4, attached). Please note plan sheets submitted are Y2 size sheets with an approximate scale of 1" : 40'. Impacts under Nationwide Permit No. 3 Permanent impacts to Perennial RPW Stream A total 64 linear feet, and are the result of rip rap installation at the downstream end of culverts. This rip rap is designed to protect the stream banks from erosion and to dissipate the energy of water exiting culverts. There will be 40 linear feet of rip rap installed on the stream banks downstream of the Eagle Glen Way culvert. No rip rap will be placed in the stream bed at this point (Plan Sheet 4, Sta. 13+06 to 13+46, attached). There will be 41 linear feet of rip rap installed on the stream banks downstream of the Gleneagles Road culvert, there is already 32 linear feet of serviceable rip rap apron at this location(Photograph B, enclosed), resulting in a net impact of 9 linear feet. No additional rip rap will be placed in the stream bed at this point (Plan Sheet 4A, Sta. 10+63 to 11+04, attached). Finally, there will be a 45 linear foot rip rap apron installed downstream of the Shillington Place culvert (Plan Sheet 9, Sta. 10+76 to 11+21, attached). This rip rap apron will replace an existing 30 linear foot apron (Photograph A, enclosed), and will result in a net impact of 15 linear feet of stream bed. Permanent impacts to Seasonal RPW Stream A total 36 linear feet, and are the result of rip rap installation. There will be 20 linear feet of rip rap installed on the stream banks upstream of the Bar Harbor Lane culvert. No rip rap will be placed in the stream bed at this point (Plan Sheet 14 and 14A, Sta. 9+96 to 10+16, attached). There will be a 16 linear feet of rip rap apron installed at the outlet of an existing 48" pipe which enters the stream at station 12+50 (Plan Sheet 14A, attached). Finally, there will be a 27 linear foot rip rap apron installed below the culvert at the upstream end of the reach (Plan Sheet 14A, Sta. 13+72 to 13+99, attached). This rip rap apron will replace an existing 31 linear foot apron (Photograph C, enclosed), and will result in no net impact to jurisdictional waters. Shillington CIP August 5, 2010 Nationwide Permit No. 3 and 27 Proiect No. 2010-2718 Impacts under Nationwide Permit No. 27 Temporary impacts to Perennial RPW Stream A under NWP No. 27 A total 36 linear feet and are the result of stream enhancement. This enhancement work will include the installation of a rock vane and rock toe protection (Plan Sheet 4, Sta. 11+60 to 11+96, attached). The stream bank will be laid back, matted and planted with native vegetation. This will result in improved stream stability and reduced sediment input. A detail of the proposed enhancement is included (Plan Sheet 3, attached). Temporary impacts to Intermittent RPW Stream A under NWP No. 27 A total 214 linear feet and are the result of stream enhancement. This enhancement work will include the installation of three rock cross- vanes to provide grade control for the channel (Plan Sheet 14A, Sta. 11+58 to 13+72, attached). Unstable and eroding stream banks will be stabilized through the use of vegetated geogrids on both sides of the channel. These geogrids are constructed of Bio D Blocks, which are coconut fiber blocks with matting on the uphill and downhill sides. This product allows for the stabilization of stream banks with limited impacts to the adjacent riparian forest community. This will result in a net improvement in stream quality and stability. Details of cross vanes and vegetated geogrids are included on Plan Sheet 3 (attached) Unavoidable impacts to on-site jurisdictional waters are summarized in Table 2., below.

Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The current land use for the project area is single family residential properties, with maintained lawns and small adjacent wooded areas. Dominant vegetation within the project area consists of willow oak (Quercus phellos), water oak (Quercus nigra), box elder (Acer negundo), common blackberry (Rubus argutus), poison ivy (Toxicodendron radicans), English ivy (Hedera helix), and fescue (Festuca sp.) 3b. List the total estimated acreage of all existing wetlands on the property: 0 acre 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 1,958 linear feet 3d. Explain the purpose of the proposed project: Flooding and erosion problems within the project area have been reported by neighborhood residents and are documented in formal responses to City questionnaires and service requests. The channel upstream of Bar Harbor lane is severely eroded. The banks on the northwest side are encroaching on the property owners decorative iron fence and tree roots are continuing to be exposed (potential loss of trees into the channel). The channel bottom continues to erode and several locations of bedrock have appeared. Photographs C and D (enclosed) illustrate the existing condition of this channel. There is also a section of bank instability at 8443 Eagle Glen Way. The stream bank is eroding at this point and is threatening trees and the air-conditioning units for the residence at that site. Photograph F shows the erosion at this location. The purpose of this project is to reduce flooding, dissipate high velocity storm flows at outfalls, and reduce storm-induced erosion downstream of culverts. In addition, the project will enhance the stream channel upstream of Bar Harbor Lane and at 8443 Eagle Glen Way. 3e. Describe the overall project in detail, including the type of equipment to be used: This overall project will involve the replacement of existing culverts, replacement of existing rip rap aprons, and stream enhancement. Stream A upstream of Bar Harbor Lane will be enhanced with the use of vegetated geogrids on the banks to provide improved bank stability (Plan Sheet 14A, attached). This will result in reducing the sediment input to the stream. Vertical stability will be provided through the use of cross-vanes. Vegetated geogrids are proposed due to the limited space available. Laying back the channel banks and providing benching is not possible due to the encroachment on structures and fences, and the loss of tree canopy over the stream which would result. Rip rap aprons will be installed at culvert outlets (Plan Sheets 4, Sta. 13+06 to 13+46; 4A, Sta. 10+63 to 11+04; 9, Sta. 10+76 to 11+21; and 14A, Sta. 9+96 to 10+16, 12+50, and 13+72 to 13+99, attached). Where possible these aprons will be limited to the stream banks. A new bypass pipe will be installed between Bar Harbor Lane and Shillington Place (Plan Sheet 14, attached) to eliminate flooding at this location. This pipe will carry flow the flow from Intermittent Stream A (upstream of Bar Harbor Lane) and will tie into the existing Shillington Place culvert. The existing pipes and open stream channel between Shillington Place and Bar Harbor Lane will remain in-situ. No fill or piping of Perennial Stream A will occur and there will therefore be no impact to Jurisdictional Waters of the U.S. Page 3 of 13 PCN Form - Version 1.0 November 2008 Version B.

Will this project occur in or near an area designated as essential fish habitat? ? Yes ® No 6b. What data sources did you use to determine whether your site would impact Essential Fish Habitat? NOAA Fisheries: http://sharpfin.nmfs.noaa.gov/website/EFH_Mapper/map.aspx 7. Historic or Prehistoric Cultural Resources (Corps Requirement) 7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation ? Yes ® No status (e.g., National Historic Trust designation or properties significant in North Carolina history and archaeology)? 7b. What data sources did you use to determine whether your site would impact historic or archeological resources? A letter was forwarded to the State Historic Preservation Office (SHPO) on July 8, 2010 to determine the presence of any areas of architectural, historic, or archaeological significance that would be affected by the project. In a response letter dated July 28, 2010 (attached), the SHPO stated that they "are aware of no historic resources which would be affected by the project." CWS consulted the Charlotte Mecklenburg Historic Landmarks Commission database and found no listed properties within the project area. 8. Flood Zone Designation (Corps Requirement) 8a. Will this project occur in a FEMA-designated 100-year floodplain? ? Yes ® No 8b. If yes, explain how project meets FEMA requirements: 8c. What source(s) did you use to make the floodplain determination? Mecklenburg County GIS Page 12 of 13 PCN Form - November 2008 Version F.

Westinghouse Blvd. Charlotte, NC 28273 Subject: Shillington CIP - Improve Stream Drainage System; Charlotte, Mecklenburg County CWS Project No. 2010-2718 Dear Ms. Singleton: Dee Freeman Secretary The Natural Heritage Program has no record of rare species, significant natural communities, significant natural heritage areas, or conservation/inanaged areas at the site nor within a mile of the project area. Although our maps do not show records of such natural heritage elements in the project area, it does not necessarily mean that they are not present. It may simply mean that the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys, particularly if the project area contains suitable habitat for rare species, significant natural communities, or priority natural areas. You may wish to check the Natural Heritage Program database website at www.ncnhp.org for a listing of rare plants and animals and significant natural communities in the county and on the quad map. Our Program also has a new website that allows users to obtain information on element occurrences and significant natural heritage areas within two miles of a given location: <http://nhpweb.enr.state.nc.us/nhis/public/gmap75_main.phtml>. The user name is "public" and the password is "heritage". You may want to click "Help" for more information. NC OneMap now provides digital Natural Heritage data online for free. This service provides site specific information on GIS layers with Natural Heritage Program rare species. occurrences and Significant Natural Heritage Areas. The NC OneMap website provides Element Occurrence (EO) ID numbers (instead of species name), and the data user is then encouraged to contact the Natural Heritage Program for detailed information. This service allows the user to quickly and efficiently get site specific NHP data without visiting the NHP workroom or waiting for the Information Request to be answered by NHP staff. For more information about data formats and access, visit <www.nconemap.conl>, then click on "FTP Data Download", and then "nheo.zip" [to the right of "Natural Heritage Element Occurrences"] You may also e-mail NC OneMap at <datagC&ncmail.net> for more information.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbodya is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs.

TNWs: linear feet width (ft), Or, acres. ? Wetlands adjacent to TNWs: acres. RPWs that flow directly or indirectly into TNWs. ® Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that tributary is perennial: Stream A has been extensively piped. The lower 1,549 linear feet of Stream A was determined to be perennial. Perennial Stream A exhibited a strong bed and bank, weak sinuosity, strong in-channel structure, substrate consisting of coarse sand, gravel and cobbles, moderate flow, and an average ordinary high water width of eight feet. Biological sampling revealed a weak presence of fish and amphibians. Stream characteristics indicate that flow is present year round. Therefore, this portion of Stream A was classified as a relatively permanent water (RPW) with perennial flow according to USACE/EPA guidance. Perennial RPW Stream A scored 64 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 32.5 out of a possible 63 points on the NCDWQ Stream Classification Form (SCPL enclosed). Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are jurisdictional. Data supporting this conclusion is provided at Section III.B.

It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: A non jurisdictional swale provides an unbroken surface water connection to Jurisdictional Wetland AA which directly abutts Perennial RPW Stream A. D. DETERMINATIONS OF JURISDICTIONAL FINDINGS. THE SUBJECT WATERS/WETLANDS ARE (CHECK ALL THAT APPLY): 1. TN-Ws and Adjacent Wetlands. Check all that apply and provide size estimates in review area: ? TNWs: linear feet width (ft), Or, acres. ? Wetlands adjacent to TNWs: acres. 2. RPWs that flow directly or indirectly into TNWs. ® Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that tributary is perennial: Stream A has been extensively piped. The upper 409 linear feet of Stream A was determined to be intermittent. Intermittent Stream A exhibited a strong bed and bank, weak sinuosity, moderate in-channel structure, substrate consisting of coarse sand and fine gravel, and an average ordinary high water width of six feet. Stream characteristics indicate that continuous flow is present for at least three months in an average year. Therefore, this portion of Stream A was classified as a relatively permanent water with seasonal flow (Seasonal RPW) according to USACE/EPA guidance. Seasonal RPW Stream A scored 43 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 26.5 out of a possible 63 points on the NCDWQ Stream Classification Form (SCP1, enclosed). . Tributaries of TNW where tributaries have continuous flow "seasonally" (e.g., typically three months each year) are jurisdictional. Data supporting this conclusion is provided at Section III.B. Provide rationale indicating that tributary flows seasonally: Provide estimates for jurisdictional waters in the review area (check all that apply): ® Tributary waters: 409 linear feet width (ft).

Wetlands adjacent to but not directly abutting an RPW that flow directly or indirectly into TNWs. ? Wetlands that do not directly abut an RPW, but when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands, have a significant nexus with a TNW are jurisidictional. Data supporting this conclusion is provided at Section III.C. Provide acreage estimates for jurisdictional wetlands in the review area: acres. Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs. ? Wetlands adjacent to such waters, and have when considered in combination with the tributary to which they are adjacent and with similarly situated adjacent wetlands, have a significant nexus with a TNW are jurisdictional.
