Permits 3 and 13 Pre - Construction Notification PCN Section B 3a Existing Conditions Reach 1 Seasonal RPW Reach 1 the most upstream reach originates at a storm water conveyance outfall in a forested residential area and flows south for a distance of 403 feet This reach is intermittent and has a drainage area of 0 022 square miles (14 1 acres) The reach enters a pipe system at the northwest corner of the 4407 Sheldon Court property From there the stream system is conveyed 720 feet underground beneath Mission Hills Road and Morington Lane to an outfall at the southeast corner of the 4304 Morington Lane property The majority of Reach 1 is laterally and vertically stable due to low bank angles and bank toe protection provided by root mass The section that flows through 4413 Shelden Court is unstable due to a steeper left bank and lack of riparian buffer and toe protection Reach 1 lacks bedform diversity throughout with mostly "riffle" habitat present Throughout the middle section at 4413 Shelden Court Reach 1 has a few short riffles with long shallow runs and pools are shallow and poorly distinguished from other bed features The downstream end has deeper and more frequent pools Entrenchment ratios are high for Reach 1 (greater than 2 2) and therefore the channel is slightly entrenched The channel is fairly uniform in width and bed form Reach 1 is almost fully shaded along the forested sections of the channel and shading in the un forested section is approximately 10% Habitat structures are present but sporadic occurring primarily in the forested sections and include woody debris leaf packs and root mats The riparian buffer width exceeds 50 feet throughout much of the reach except for the section flowing through 4413 Shelden Court where there is no riparian buffer (Photo 1) The forested sections contain Chinese privet (Ligustrum smense) Reach 2 Non RPW (not jurisdictional) Reach 2 is an ephemeral swale that originates from a pipe on the western edge of the 8201 Duxbury Court property and flows north toward a forested area at the rear of the property The reach is reinforced with riprap from the pipe to approximately 10 feet downstream of the outlet Beyond the riprap reinforcement the channel flattens out and becomes indistinguishable from the floodplain approximately 25 feet downstream of the pipe outlet The total drainage area at the downstream end is 0 008 square miles (5 0 acres) Reach 2 lies entirely within the maintained yard of 8201 Duxbury Court and is bordered by a privacy fence on the left top of bank The reach becomes dispersed approximately 25 feet downstream of the pipe outlet and flows into a forested area approximately 30 feet downstream from the culvert No geomorphological features or stream hydrology were present at the time of assessment Reach 2 is stable and does not exhibit erosion but it has no riparian buffer habitat structures or grade control structures No longitudinal profile or cross sections were surveyed on Reach 2 because of the absence of geomorphological features Reach 3 Seasonal RPW Reach 3 originates from a pipe system at the southeast corner of the 4304 Morington Court property The reach then flows a distance of 140 feet through portions of 4303 and 4301 Claybury Court before draining into a pipe system on the eastern side and to the rear of 3327 New Hampshire Drive (Photo 2) The reach has a drainage area of 0 082 square miles (52 7 acres) The entire reach flows through residential backyards with a forested buffer of approximately 20 feet on the right bank and 40 feet on the left bank Reach 3 is laterally and vertically stable due to low bank angles bank toe protection provided by root mass and cobble and a moderate amount of grade control in the form of several boulders and large cobbles throughout the reach Debris including two bicycles was found in the channel and on the banks Reach 3 has short riffles throughout and pools tend to be short and shallow Reach 3 has an average riffle length of 11 5 feet The pool depths average 0 8 feet with a pool to-pool spacing of 27 3 feet This section of Wiseman Creek is fairly straight with only a few shallow bends (sinuosity = 1 1) and has a slope of 0 15 percent Typically the cross sectional area is 6 2 square feet with a width to depth ratio ranging from 7 3 to 9 4 Bank heights ranged from 2 7 to 2 9 feet The typical bed material found in this section is fine gravel with an average D50 of 5 2 mm The majority of the bed material throughout the reach consists of gravel and sand with numerous cobbles and boulders the pools contain comparatively higher levels of silt Entrenchment ratios are high for Reach 3 (greater than 2 2) and therefore the channel is slightly entrenched Reach 3 is a well shaded cobble - gravel riffle /run system Habitat structures are somewhat sparse throughout the reach and consist of large rocks exposed roots and overhanging shrubs in the upper portion of the reach The presence of exposed roots and overhanging shrubs is sporadic within the downstream portion of this reach Reach 4 RPW Reach 4 is a perennial stream that originates on the south side of Sunflower Road at New Hampshire Drive and is 768 feet in length This reach has a drainage area of 0 183 square miles 017 4 acres) The reach terminates at a culvert dust upstream of Valley Grove Road Reach 4 flows entirely through residential properties Most of the reach has a forested buffer of 25 to 30 feet on both banks Reach 4 is laterally and vertically stable due to forested banks with moderate bank angles bank toe protection provided by root mass cobble and boulders and grade control in the form of boulders and cobbles throughout the reach There are only a few areas of minor bank erosion (Photos 3 and 4) Chinese privet is common throughout the reach Reach 4 has short cobble riffles with long shallow runs and a low frequency of pools that occur primarily in the downstream portion of the reach The riffles in Reach 4 average 11 2 feet in length The pool depths average 1 3 feet with a pool to-pool spacing of 11 2 feet Entrenchment ratios for Reach 4 range from 2 7 to 3 8 and therefore the channel is slightly to moderately entrenched Reach 4 is partially to fully shaded Habitat structures consist of large rocks and isolated areas of undercut banks and overhanging shrubs The riparian buffer is forested and is characterized by scattered mature trees and a fairly open understory of herbaceous species Chinese privet is common throughout the reach The buffer width along both banks ranges from 25 to 30 feet throughout most of the reach The downstream portion of the reach adjacent to the box culvert has little to no buffer and the banks are reinforced with riprap Reach 5 RPW Reach 5 is a perennial stream that originates at Valley Grove Road and flows for 1 391 feet before terminating 105 feet west of Cross Winds Roads between 3215 and 3221 Cross Winds Road It has a drainage area of 0 223 square miles (142 7 acres) Residential lots border both sides of the reach for the entire length Reach 5 is vertically stable due to large amounts of bedrock that serve as grade control preventing the channel from downcutting However there are several areas of active bank erosion throughout the reach (Photos 5 10) An area from 3411 to 3405 Arrow Lane is exhibiting heavy erosion on the left bank which is causing instability in this section The lower portion of the reach from 3301 Cross Winds Road to the pipe inlet is straight and confined on both sides Entrenchment ratios for Reach 5 range from 2 2 to 5 6 and therefore the channel is moderately entrenched Reach 5 is a partially to fully shaded riffle /run system composed primarily of cobble and gravel with frequent bedrock outcroppings Habitat structures are sparse except for large rocks which are common throughout the entire reach and isolated areas of undercut banks and woody debris The riparian buffer is forested throughout most of the reach and is typically 30 feet wide on each bank however in some sections the buffer narrows or is absent The understory tends to be relatively open and is comprised of shrubs and herbaceous species Chinese privet is common along the banks Reach 6 RPW Reach 6 originating behind 3212 Cross Winds Road and flowing 140 feet into a pipe system at the southeast corner of 3206 Cross Winds Road is a perennial stream with a drainage area of 0 235 square miles 0 50 4 acres) The channel flows through portions of two residential yards and has a forested buffer of 10 to 15 feet on each side of the channel throughout most of the reach The buffer is narrow to absent on the left bank at the upstream end of the reach where severe bank erosion is encroaching on a privacy fence on the 3212 Cross Winds Road property (Photo 11) Reach 6 is unstable at the upstream end due to severe erosion on left bank The banks are typically 9 feet high and bank angles are typically 45 degrees with steeper bank angles at the upstream end where the banks are severely eroded The channel has a roughly 90 degree bend at the upstream end and high flows are causing severe erosion at this bend The high banks prevent the channel from having sufficient floodplain access The lower portion of the reach is generally straight and more stable than the upstream end Bank toe protection is provided by root mass and cobble in the lower portion of the reach Reach 6 is a partially shaded riffle/run system composed primarily of cobble and gravel Pool depths are generally shallow and habitat structures are sparse except for cobble and isolated areas containing small woody debris Reach 7 RPW Reach 7 originates from a twin culvert pipe system adjacent to 8835 Idlewild Road and is a perennial stream that flows 160 feet into McAlpine Creek The reach flows through a vacant undeveloped lot and has a drainage area of 0 240 square miles 0 53 8 acres) A forested buffer approximately 20 to 30 wide lines each side of the channel Reach 7 is laterally and vertically stable due to well vegetated buffers bank toe protection provided by root mass boulders and cobble and a moderate amount of grade control in the form of boulders and large cobbles throughout the reach The banks are typically approximately 11 feet high and bank angles are approximately 40 degrees throughout the channel The reach is straight and slightly entrenched Pool depths are shallow and habitat structures include cobbles and boulders some overhanging vegetation and isolated areas of woody debris No protected species are known to occur in the project area and none were observed during field investigations The proposed project is not likely to adversely affect any protected species The US Fish and Wildlife Service will be provided a courtesy copy of the PCN for their review The North Carolina State Historic Preservation Office (NCSHPO) did not list any historic properties in the

(permanent) 140 Total Impacts (all) 1 036 Impact Descriptions Impact S1 (Figure 6, Sheets 4, D2, EC2, and EC4) Stream Impact S1 will involve the replacement of two existing undersized 54 reinforced concrete culverts beneath Braewick Place and adjacent residential properties with 292 linear feet of 11 x7 reinforced concrete box culvert (RCBC) set at a lower elevation This impact also includes replacing an existing and currently serviceable rip rap apron below the existing culvert s downstream end with a rip -rap lined plunge pool (40 linear feet) Minor bank grading will be required to accommodate the increased culvert width and depth Typical bank grading to accommodate larger end walls (impact locations S1 S3 S4 & S7 consist of grading the banks back at a 2 1 slope installing coir fiber matting The banks will be planted with a mixture of trees shrubs and non invasive channel seeding Because of the culvert s length necessary slope and the presence of bedrock it will be installed at the same elevation as the channel at both the upstream and downstream ends While the proposed culvert s alignment will not exactly match the existing one its upstream headwall will be in the same location as the existing one To increase the distance between the proposed culvert s downstream headwall and an existing sanitary sewer the proposed downstream headwall will be approximately four feet upstream of the existing one Also to ensure that impacts to downstream aquatic habit are avoided and minimized to the maximum extent practicable a temporary rock check dam (5 linear feet wide) will be installed in the stream channel approximately 40 downstream from the proposed plunge pool Because the proposed culvert will not enclose any existing stream channel and the proposed plunge pool will occupy the same footprint as the existing displaced rip -rap and concrete debris no permanent stream impacts are anticipated During construction a pump around will be installed 10 feet upstream of the proposed upstream headwall and will discharge into the proposed plunge pool Impact S1 will result in 85 linear feet of temporary stream impacts within Reach 7 and is proposed for authorization under NWP 3 — Maintenance Impact S2 (Figure 6, Sheets 4, 16, and S1) Stream Impact S2 includes hard stabilization of bed and bank along Reach 6 which is located directly between Braewick Place culvert and Cross Winds Road pipe systems (impacts S1 and S3) The existing channel is extremely degraded with eroding vertical banks little bedform diversity and large sediment deposits The bank loss threatens residential yards and structures Hard stabilization is required due velocity depth shear stress and the lack of allowable area for softer stabilization approaches The requirement to convey the 100 year storm event which prevents the existing slab on grade houses from flooding requires box culverts at Braewick Place and Cross Winds Drive The proximity of these closed systems to the houses further requires the proposed RCBC to be deeper than the original pipe systems, which also requires the channel to be lowered approximately 2 feet Impact S2 includes constructed planted benches in the proposed block wall to soften the design and provide channel shade habitat and a more constricted low flow channel The rip -rap bed stabilization also includes two pool habitats that will provide bedform diversity and refugia both of which are currently lacking These features were specifically designed to provide better habitat and morphology than traditional hard stabilization techniques Impact S2 will result in 140 linear feet of permanent stream impacts within Reach 6 from hard channel stabilization and is proposed for authorization under NWP 3 — Maintenance Impact S3 (Figure 6, Sheets 5 and EC4) Stream Impact S3 includes the replacement of an existing undersized 72 corrugated metal pipe (CMP) beneath Cross Winds Road and adjacent residential properties with 400 linear feet of 10 x6 RCBC at or near the existing pipes elevation Minor bank stabilization (see description at S1) will be required at the pipe system s upstream and downstream ends to accommodate its increased width As with Impact S1 because of the RCBC s length grade and the presence of bedrock this pipe system s bottom will be installed at the same elevation as the channel While the proposed pipe system alignment will not exactly match the existing one both its upstream and downstream headwalls will be in the same locations as the existing ones Because the proposed pipe system will not enclose any existing stream channel no permanent stream impacts are anticipated During construction a pump around will be installed 10 feet upstream of the proposed upstream headwall It will discharge 10 feet downstream of the proposed pipe outlet S3 will result in 20 linear feet of temporary stream impacts within Reach 5 and is proposed for authorization under NWP 3 — Maintenance Impact S4 (Figure 6, Sheets 10 11, D2, and EC6) Stream Impact S4 includes the replacement of existing undersized 48 and 54 CMPs beneath Sunflower Road and New Hampshire Drive with proposed 67 linear feet of 6 x4 RCBC and 541 linear feet of 66 reinforced concrete pipe (RCP) This maintenance activity will also include the installation of 50 linear foot of riffle grade control structure at the outlet for scour protection The bottom 1 5 of this structure will be composed of mixed riprap on filter fabric and will be located below the stream bed An additional foot of native soil salvaged from the existing stream bed mixed with #5 stone (gravel) will be installed above the rip rap to insure that the reach is returned to its pre - construction condition Once installed the riffle will act as a grade control (not an energy dissipater) below the downstream headwall which will protect it from being undercut A temporary 5 linear foot wide check dam will be installed over the riffle Minor bank stabilization (see S1 description) will be required at the pipe system s upstream and downstream ends to accommodate its increased width As with Impacts S1 and S3 because of the pipe system length grades and the presence of bedrock these pipe inverts will be installed at the same elevation as the channel The proposed pipe system alignment almost exactly matches the existing one and both its upstream and downstream headwalls will be in the same locations as the existing ones Because the proposed pipe system will not enclose any existing stream channel and the riffle grade control structure will be returned to its original elevation grade and substrate no permanent stream impacts are anticipated During construction pump arounds will be installed 10 feet upstream of the proposed upstream headwalls and will discharge into the proposed riffle grade control Impact S4 will result in 80 linear feet of temporary stream impacts within Reach 4 and is proposed for authorization under NWP 3 — Maintenance Impact S5 (Figure 6, Sheets 6, D1, EC5, and EC2) Stream Impact S5 consists of 378 linear feet of soft bank stabilization along Reach 5 adjacent to Arrow Lane The existing channel banks are unstable and contribute to decreased water quality and loss of aquatic habitat The proposed stabilization will prevent further erosion and loss of residential yards Specific stabilization measures include grading channel banks to a minimum 2 to 1 slope placement of coir erosion control matting live stakes bare root plantings and permanent riparian seed mix This work will also require the temporary installation of two 15 linear foot wide gravel stream crossings and one 5 linear foot wide check dam The crossings will be necessary to provide equipment access to complete the bank stabilization activities The check dam will be necessary to ensure that accidental /unintentional impacts to aquatic resources are avoided and minimized to the maximum extent practicable Stream Impact S5 will result in 378 linear feet of temporary stream impact within Reach 5 and is proposed for authorization under NWP 13 — Bank Stabilization Impact S6 (Figure 6, Sheets 9, D1, EC5, and EC2) Stream Impact S6 consists of 278 linear feet of soft bank stabilization along Reach 4 between Valley Grove Road and Sunflower Road The existing channel banks are unstable and contribute to lowered water quality and loss of aquatic habitat The proposed stabilization will prevent further erosion and loss of residential yards Specific stabilization measures include grading channel banks to a minimum 2 to 1 slope placement of coir erosion control matting live stakes bare root plantings and permanent riparian seed mix This work will also require the temporary installation of a 15 linear foot wide gravel stream crossing and a 5 linear foot wide check dam The crossing will be necessary to provide equipment access to complete the bank stabilization activities Impact S6 also includes stabilization of a non jurisdictional storm water channel that enters the left bank Stream Impact S6 will result in 278 linear feet of temporary stream impact within Reach 4 and is proposed for authorization under NWP 13 — Bank Stabilization Impact S7 (Figure 6, Sheets 12 14 and 132) Stream Impact S7 will result from the replacement of an existing undersized closed system beneath Morington Lane and adjacent properties The proposed closed system will be located within the existing pipe system footprint and will not result in the loss of open channel The new pipe system will be set at a lower elevation and minor grading and bed stabilization will be installed to minimize channel erosion The maintenance activity will also include 25 linear feet of riffle grade control above the upstream headwall of Reach 2 and 30 linear feet of riffle grade control below the downstream headwall (Reach 3) of the main closed system During construction a pump around will be installed within the proposed Reach 2 riffle grade control It will discharge within the proposed downstream Reach 3 riffle grade control Because both pump around locations will be installed within the proposed riffle grade control structures no temporary stream impacts are anticipated Impact S7 will result in 55 linear feet of temporary stream impacts within Reaches 2 and 3 and is proposed for authorization under NWP 3 — Maintenance PIZ �0 er Hilliard pr y

Report Wiseman Storm Drainage Improvements This jurisdictional delineation (JD) report is submitted on behalf of Charlotte- Mecklenburg Storm Water Services Mecklenburg County NC 1 PROJECT INFORMATION A Waters of the US (including wetlands) delineation was completed during April 2009 for the Wiseman project area in Mecklenburg County NC This memorandum presents the methods results and conclusions for the above referenced project The project area was defined as the extent of the closed and open channel drainage systems in the Wiseman watershed Specifically the primary drainage feature originates above Mission Hills Road and flows south into McAlpine Creek which I located dust south of Braewick Place 2 METHODS Jurisdictional Waters of the US, including wetlands are defined by 33 CFR Part 328 3 and are protected by Section 404 of the Clean Water Act (33 USC 1344) which is administered and enforced by the US Army Corps of Engineers ( USACE) The delineation of jurisdictional waters of the US was performed utilizing the Routine On Site Determination Method as defined in the Corps of Engineers Wetlands Delineation Manual (Eastern Mountains and Piedmont Supplement) This technique uses a three parameter approach which requires positive evidence of • Hydrophytic vegetation • Hydric soils • Wetland hydrology Areas exhibiting the above three wetland characteristics as well as surface waters were marked in the field with sequentially numbered pink and black stripped surveyors tape The origins of perennial and intermittent streams were also delineated using USACE and NCDWQ guidance documents and marked with pink and black stripped surveyors tape The delineation of jurisdictional wetland boundaries on the site consisted of in house research and field investigations In house research included a review of information sources such as US Geologic Survey 7 5 minute topographic quadrangle aerial photography and National Wetlands Inventory (NWI) maps Subsequent to the in house review wetlands and surface waters were delineated in the field utilizing the above stated methodology 3 RESULTS AND DISCUSSION No wetlands are indicated within the project area on either the USGS 7 5 minute topographic quadrangle map (Mint Hill NC 1993) or the NWI mapping for the project site A review of available aerial photography did not indicate any obvious wetland areas Both the Quadrangle and Mint Hill NC NWI map show an unnamed tributary to McAlpine Creek in the project area Subsequent to the in house research a field investigation was performed to delineate waters of the US No wetlands were delineated in the project area The project area is composed entirely of developed residential properties and roadways The open drainage channels were typically incised further draining any potential relic wetlands No hydric soil was encountered and no wetland hydrology indicators were observed in the project area. Common facultative wetland vegetation such as red maple (Acer rubrum), willow oak (Quercus phellos), and Chinese privet (Ligustrum sinense) were observed. However, these species are also indicative of disturbance, and alone do not indicate the presence of jurisdictional wetlands. The unnamed tributary to McAlpine Creek was identified as a Relatively Permanent Water (RPW) at the downstream end of the project area. This channel transitions to a Seasonal RPW higher in the watershed. This primary drainage channel is a jurisdictional stream. One non - jurisdictional channel was identified between Duxbury Court and Morrington Drive. This channel was ephmemeral and lacked morphological and hydrologic indicators typical of RPWs and Seasonal RPWs. The attached exhibit details the stream reach identification numbers and location. Existing conditions at the time of the site visit are described below. A Jurisdictional Determination Form (Rapanos), NCDWQ Stream Identification Forms, and USACE Stream Quality Assessment Worksheet are also attached. Reach 1: Seasonal RPW Reach 1, the most upstream reach, originates at a storm water conveyance outfall in a forested residential area, and flows south for a distance of 403 feet. This reach is seasonal and has a drainage area of 0.022 square mile (14.1 acres). The reach ends at a culvert at the northwest corner of the 4407 Sheldon Court property. From there, the stream system is conveyed 720 feet underground beneath Mission Hills Road and Morington Lane, to an outfall at the southeast corner of the 4304 Morington Lane property. The majority of Reach 1 is laterally and vertically stable due to low bank angles and bank toe protection provided by root mass. The section that flows through 4413 Shelden Court is unstable due to a steeper left bank and lack of riparian buffer and toe protection. Reach 1 lacks bedform diversity throughout with mostly "riffle" habitat present. Reach 1 scored 25 points on the NCDWQ Stream Identification Form, which classifies the channel as intermittent (seasonal RPW). Reach 2: Non -RPW (not jurisdictional) Reach 2 is an ephemeral swale that originates from a culvert on the western edge of the 8201 Duxbury Court property, and flows north toward a forested area at the rear of the property. The reach is reinforced with riprap from the culvert to approximately 10 feet downstream of the culvert. Beyond the riprap reinforcement, the channel flattens out and becomes indistinguishable from the floodplain approximately 25 feet downstream of the culvert. The total drainage area at the downstream end is 0.008 square mile (5.0 acres). No geomorphological features or stream hydrology were present at the time of assessment. Reach 2 scored 8.5 points on the NCDWQ Stream Identification Form, which classifies the channel as ephemeral (non RPW). Reach 3: Seasonal RPW Reach 3 originates from a culvert at the southeast corner of the 4304 Morington Court property. The reach then flows a distance of 140 feet through portions of 4303 and 4301 Claybury Court before draining into a culvert on the eastern side and to the rear of 3327 New Hampshire Drive. The reach has a drainage area of 0.082 square mile (52.7 acres). The entire reach flows through residential backyards with a forested buffer width of approximately 20 feet on the right bank and 40 feet on the left bank. Reach 3 is laterally and vertically stable due to low bank angles, bank toe protection provided by root mass and cobble, and a moderate amount of grade control in the form of several boulders and large cobbles throughout the reach. Reach 3 scored 28 points on the NCDWQ Stream Identification Form, which classifies the channel as intermittent (seasonal RPW). Reach 4: RPW i Reach 4 is a perennial stream that Y originates on the south side of *` Sunflower Road at New Hampshire Drive, and is 768 feet in length. This reach has a drainage area of 0.183 square miles (117.4 acres). The reach terminates at a culvert just upstream of Valley Grove Road. Reach 4 flows entirely through residential properties. Most of the reach has a forested buffer width of 25 to 30 feet on both banks. Reach 4 is laterally and vertically stable due to forested banks with moderate bank angles, bank toe protection provided by root mass, cobble, and boulders, and grade control in the form of boulders and cobbles throughout the reach. There are only a few areas of minor bank erosion. Reach 4 scored 33.5 points on the NCDWQ Stream Identification Form, which classifies the channel as perennial (RPW). Reach 5: RPW Reach 5 is a perennial stream that originates at Valley Grove Road, and flows for 1,391 feet before terminating 105 feet west of Cross Winds Road between 3215 and 3221 Cross Winds Road. It has a drainage area of 0.223 square mile (142.7 acres). Residential lots border both sides of the reach for the entire length. Reach 5 is vertically stable due to large amounts of bedrock that serve as grade control, preventing the channel from downcutting. However, there are several areas of active bank erosion throughout the reach. An area from 3411 to 3405 Arrow Lane is exhibiting heavy erosion on the left bank, which is causing instability in this section. The lower portion of the reach, from 3301 Cross Winds Road to the culvert, is straight and confined on both sides. Reach 5 scored 34.5 points on the NCDWQ Stream Identification Form, which classifies the channel as perennial (RPW). 4 Reach 6: RPW Reach 6, originating behind 3212 Cross X ? Winds Road and flowing 140 feet into a culvert at the southeast corner of 3206 Cross Winds Road, is a perennial stream with a drainage area of 0.235 square mile 0 50.4 acres). The channel flows through portions of two residential yards, and has a forested buffer of 10 to 15 feet on each side of the channel throughout most of the reach. The buffer is narrow to absent on the left bank at the upstream end of the reach where severe bank erosion is encroaching on a ~� privacy fence on the 3212 Cross Winds Road property. Reach 6 is unstable at the upstream end due to severe erosion on left bank. The banks are typically 9 feet high, and bank angles are typically 45 degrees, with steeper bank angles at the upstream end where the banks are severely eroded. The channel has a roughly 90 degree bend at the upstream end, and high flows are causing severe erosion at this bend. The high banks prevent the channel from having sufficient floodplain access. The lower portion of the reach is generally straight and more stable than the upstream end. Reach 6 scored 33.5 points on the NCDWQ Stream Identification Form, which classifies the channel as perennial (RPW). Reach 7: RPW Identification Form, Reach 7 originates from twin culverts adjacent to 8835 Idlewild Road, and is a perennial stream that flows 160 feet into McAlpine Creek. The reach flows through a vacant, undeveloped lot, and has a drainage area of 0.240 square mile (153.8 acres). Reach 7 is laterally and vertically stable due to well- vegetated buffers, bank toe protection provided by root mass, boulders, and cobble, and a moderate amount of grade control in the form of boulders and large cobbles throughout the reach. Reach 7 scored 37 points on the NCDWQ Stream which classifies the channel as perennial (RPW).

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 waterbody° 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

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 1 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 2 Significant nexus findings for

significant nexus below based on the tributary in combination with all of its adjacent wetlands then go to Section III D The tributary has the capacity to carry pollutants and nutrients to a TNW and offers some treatment of pollutants prior to reaching a TNW The tributary and its adjacent wetlands also provide a contiguous wetland/aquatic habitat down to the TNW D DETERMINATIONS OF JURISDICTIONAL
