This delineation is only for the portions of the properties where the alignment of the trail will occur, a corridor approximately twenty feet wide. The project consists of replacing stream crossings for an existing .82 mile section of paved asphalt greenway trail and construction of new crossings for an additional .84 mile of proposed new paved asphalt greenway. One bridged crossing over a perennial stream (S-1) will be replaced, one perched culverted crossing over a perennial stream (S-2) will be replaced, and one new culverted crossing will be constructed over a perennial stream (S-7) for total new stream impacts of 92 linear feet. Several other swale bridge crossings will be placed over non jurisdictional ephemeral ditches. Wetlands have not been identified along the propsed trail route since it traverses mostly mowed grass upland and along the edge of a portion of gas line easement. Field delineations were conducted July 1, 5, and 14, 2016. A copy of this document is also being sent to Alan Johnson at the N.C. Division of Water Resources for verification. Could you please review the attached for a preliminary verification. Labeled flagging has been placed at all stream and wetland sample points and at the OHWM of all jurisdictional streams for a distance of approximately 100 feet at each crossing. Wetlands were not observed on this site. Flags have been not been surveyed but a plan and profile sketch of each crossing showing flag locations is on each NCDWQ Stream Identification Form. If you would like to schedule a site visit, please let me know and we will do so at your earliest convenience. Please do not hesitate to contact me if you should have any questions or comments. I look forward to your reply. Respectfully, Craig R.

C n erre irw / P SIG1 • 140 Cffi- F— 163 • Hiy6 5l,,,I, 0 I''C • 28077 0 (7(4) )4GX79.3 Abersham Greenway Allison Farm Park / Fisher Farm Park Mecklenburg County, NC Site Investigations Conducted July 1, 5, and 14, 2016 Site Context The Abersham Greenway Study Area consists of a linear greenway route that is approxi- mately 4.330 linear feet (82 mile) of existing trail and 4,435 linear feet (84 mile) of proposed new trail. The trail route is located in Tax Parcel ID numbers 00304103 and 00311104 located in Mecklenburg County, NC within existing Allison Farm Park and Fisher Farm Park. The existing trail consits of a 10' wide asphalt paved surface and is a part of the West Branch Greenway. The entire site is located within the Yadkin River Basin and appears on the Cornelius, NC quad of the U.S. Geological Survey. The site generally occurs within the sub -basin of West Branch Rocky River. The Study Area runs generally in a north south direction and occurs parallel to the West Branch Rocky River. Historically, the site has been used agriculture and pasture. A natural gas line easement occurs parallel to the trail for a portion of the length of the undeveloped section. The purpose of this project is to renovate portions of the existing trail, replace existing bridge and stream crossings, construct new trail length, and construct new stream and swale crossings. Purpose of StudX This site investigation was conducted to determine if the site contains areas which would be considered as wetlands or waters under sections 401 and 404 of the Clean Water Act and subject to the permitting and regulatory authority of the U.S. Army Corps and the NC Division of Water Re- sources. The study was conducted to identify the approximate location and extent of areas which exhibit the field indicators of wetlands or surface waters and to delineate these areas in the field and on a topographic map of the site. Site Hydrologic Features The primary watercourse in the vicinity of the site is West Branch Rock River (NC Stream Index 13-17-3 and Hydrologic Unit Code 03 040105) within the headwaters of the Rocky River (TNW). The site is parallel to West Branch Rocky River which is the nearest FEMA Floodplain downstream of the site. Rocky River is the nearest Traditionally Navigable Water (TNW) located approximately 1.5 miles downstream from the nearest point of the Study Area. The entire length of West Branch Rocky River is classified as C in the Water Quality Classifications for the Yadkin Pee Dee River. The USGS quad map indicates that the route of the greenway does not cross named streams named streams but is does cross three intermittent blue line streams at S-1, S-2, and S-7. West Branch Rocky River and its tributaries are not listed as a 303(d) impaired stream. National Wetland Inventory maps indicate that this site has no areas mapped as wetland. Mecklenburg Polaris 3G GIS identifies three intermittent blue line streams at S-1, S-2, and S-7. The entire route of the greenway is along the edge of the 100 year Flood Plain as identified by FEMA and the Mecklenburg Polaris 3G GIS. Four man-made ditches were identified at S-3, S-4, S-5, and S-8. There was no channel or wetlands present at S-6, only a broad area of occasional surface flow. e�ir�e / uESIGN • Post 0f{ice Box 163 0 H 9h Shoals 0 NC 0 28077 0 (704) 240-0793 Source: USGS 7.5 minute quad, Cornelius, NC Abersham Greenway e scale: 1"=2000' Mecklenburg County, NC NORTH Project Location 4855 ll/ SE !M OF'£SVILLE"( `iP, 4y i0 1 4 70 000 FEE i 120 197, - PE41A V 1 � ) � � r`6 �'PUBNh`iIvv, i A I � OEM) Pt �FOi7i PFO (S 4 r \ r l drew► r 6 2421 S -m7` r r 1--PUBNti 1; 2—B (� PF 1 , : PEMIA PT M, ' PFOIc PFa( /o-_-Pu9Hh �� PF01A PFOIA� TFOIC A t > �1811h Vit' Pti rC U PSSIA n" PFOIA, PFJOfAIN ii 3 Source: USFWS National Wetlands Inventory, Cornelius, NC (199 1) Abersham Greenway Scale: I"=2000' Mecklenburg County, NC NORTH National Wetlands Inventory Yadkin -Pee Dee River Basin Name Index Number Classification Class Date (Description J Special Designation West Branch Rocky River 13-17-3 C 09/01/74 From source to Rocky River West Camp Branch 12-46-2-2-3-1 C;Tr,ORW 12/01/92 From soruce to Cove Creek West Double Creek 12-67-1 C 04/06/55 From source to East Double Creek West Fork Little River 13-25-15 C 08/03/92 From source to Little River West Prong Hamer Creek 13-25-37-2-1 C 09/01/74 From source to Middle Prong Hamer Creek West Prong Little Yadkin River 12-77-1-(2) WS -Iv 08/01/98 From a point 0.3 mile upstream of Stokes County Stokes County SR 1160 to Little Yadkin River West Prong Little Yadkin River 12-77-1-(1) C 08/01/98 From source to a point 0.3 mile upstream of Stokes County SR 1160 West Prong Moravian Creek 12-39-1 C 04/06/55 From source to Moravian Creek West Prong Roaring River (North) 12-46-1-(5) C 04/06/55 From Wilkes County SR 1731 to Roaring River West Prong Roaring River (North) 12-46-1-(1) C;Tr 07/01/73 From source to Wilkes County SR 1731 West Swan Creek 12-51-1-(1) C 08/01/98 From source to a point 0.4 mile upstream of Wilkes County SR 2303 West Swan Creek 12-51-1-(2) WS -Iv 08/01/98 From a point 0.4 mile upstream of Wilkes County SR 2303 to Swan Creek J Westfield Creek 13-46 C 08/03/92 From source to N.C.-S.C.

Soils which have been mapped for this siteconsit of the following series: MO Monocan Loam, 0 to 2% slopes, Frequently Flooded HeB Helena Sandy Loam, 1 to 8% slopes None of the soil series on this site are mapped as being entirely hydric, however both the Monocan and Helena soils are listed by the NRCS as having hydric inclusions in depressions. Undisturbed upland soils exhibited very high chroma matrix colors throughout the profile with colors of 10YR4/4 to 7.5YR 4/4 occurring to a depth of at least 16 inches. The soils at Sample Plot 2-13 have been disturbed by grading, fill, and road access for the construction of a natural gas pipeline in 2013. Pronounced indicators of hydric soils were not observed at sample plot locations of the site. It is expected that although these areas may experience occasional overbank flooding, they are not subject to prolonged periods of saturation or inundation. e�ir�e / uESIGN • Post 0f{ice Box 163 0 H 9h Shoals 0 NC 0 28077 0 (704) 240-0793 Source: USDA-NRCS Web Soil Survey Mecklenburg County Abersham Greenway e scale: I"=1500' Mecklenburg County, NC NORTH USDA-NRCS Soils a r oa rpC e ?yam PaE CeD2 CeD2 B2 f¢ A .

A short section of the existing paved trail between S-3 and S-4 goes through a n existing forested area. Trees occur for short distances at other points along the trail route where it crosses surface drainage features such as tributaries and ditches. The natural gas pipeline between S-4 and S-7 is comprised of herbaceous upland successional species. The proposed trail route only crosses this commmunity in one location. The section of trail route between S-7 and S-8 occurs along the edge of a recently constructed natural gas pieline easement. This area was previously forested and has regrown in a mix of hydro- phytic and non-hydrophytic herbaceous successional vegetation dominated by Juncus effusus in the lower areas. The sample plot conducted at 2-13 has identified a dominance of hydrophytic vegetation along the edge of the remaining forest but the soils and hydrology indicate that the area does not remain saturated or inundated for significant perids followng occasional flooding The distribution of dominant species corresponds strongly with topographic position and observation of changes in soil characteristics and hydrologic indicators. In the lowest portions of the site the dominant species were entirely hydrophytic. The majority of the route of the existing and proposed trail occur in maintained grassed upland. e�ir�e / uESIGN • Post 0f{ice Box 163 0 H 9h Shoals 0 NC 0 28077 0 (704) 240-0793 Abersham Greenway Mecklenburg County, NC Source: Mecklenburg County Polaris 3G GIS 2016 Aerial Photography Scale: I"=300' 2016 Aerial Photography NORTH Southern Section Wetland Determination Methodoloa Those portions of the site which have been identified as jurisdictional under Section 404 of the Clean Water Act or Section 10 of the Rivers and Harbors Act include waters and wetland areas which satisfy the definition of a wetland in the Xorps of Engineers Wetlands Delineation Manual, Technical Report Y-87-11] January 1987, U.S. Army Corps Environmental Laboratory and subse- quent Corps and DWQ guidance. Methodology used in this study include the use of the 1987 Corps of Engineers Wetland Delineation Manual, Interim Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region Environmental Laboratory U.S. Army Corps of Engineers July 2010, U.S. Supreme Court and U.S. EPA guidance for determi- nation of Significant Nexus, and the North Carolina Division of Water Quality Methodology for Identification of Intermittent and Perennial Streams and Their Origins Version 4.11 Effective Date: September 1, 2010. Jurisdiction may potentially be identified as Traditionally Navigable Waters (TNW), Perennial Streams, Relatively Permanent Waters (Intermittent RPW), Seasonal Intermittent RPW, Intermittent Non-RPW, Impoundments, Adjacent Wetlands, and Abutting Wetlands. Ephem- eral Channels and Isolated Waters are typically not jurisdictional without a Significnt Nexus Deter- mination. A routine on-site determination method utilizing the multi -parameter approach was imple- mented to identify the upper wetland boundary of all areas which satisfy the three parameters as described in the manual: 1. Hydrophytic Vegetation 2. Hydric Soils 3. Wetland Hydrology The following methodology was utilized to make the determination: 1. Preliminary data gathering and synthesis. Data sources include: USGS Quadrangle Maps National Wetlands Inventory Maps USDA-NRCS Soil Survey for Mecklenburg County Mecklenburg County Flood Data Mecklenburg County topography & tax parcel data Mecklenburg County aerial photography Applicant provided plat map documents 2. Selection of Routine on-site Determination Method 3. Identification of Plant Community Types The site was divided into its major vegetation communities for charactization. Those portions of the site which exhibited characteristic hydrophytic vegetation were reviewed for presence of hydric soils and evidence of wetland hydrology. 4. Transects were established approximately perpendicular to the major water courses for location of sample observation points. 5. Observation points were located along transects within each major vegetation community to observe and record the characteristics of hydrophytic vegetaion, hydric soils and wetland hydrol- ogy. e�ir�e / uESIGN • Post 0f{ice Box 163 0 H 9h Shoals 0 NC 0 28077 0 (704) 240-0793 Each sample observation point (sample plot) consisted of one or more 18-24" deep test pits dug with a spade to characterize soils and hydrology, and a thirty foot radius area to characterize tree and woody vine species; a fifteen foot radius area to characterize a representative sample of the sapling, shrub and woody vine species; and a five foot radius to document herbaceous plant species. All observed data was recorded on an appropriate Data Form as well as notation of Atypical Conditions and Normal Environmental Conditions. A determination was made whether or not the sample plot was a wetland based upon available and observed data. Sample plots are identified in the field with numbered pink and orange surveyor's flagging. If a wetland/non-wetland determination was made at a sample plot, an upper wetland bound- ary was assumed to occur between wetland plots and non -wetland plots. Numerous additional test pits were dug along each transect to identify the boundary location. Once boundaries had been located along each transect, the characteristics at this point were utilized to determine the boundary location between transects until the entire site had been divided into wetland and non - wetland areas. This boundary was then confirmed and adjusted through the use of visual obser- vation and additional test pits on either side of the line. Soil profiles were observed using a Dutch auger and a one inch tube sampler. Estimated wetland boundaries were measured in the field and sketched on a topographic map of the site. There were no areas identified as wetland within the Study Area rout of the existing or proposed trail alignment. 6. Tributary channels on the site were demarcated and recorded by walking the length of the channel for fifty feet upstream and downstream of the existing or proposed crossing. Stations were established at a typical and representative location along the channel length for observation, pho- tography and measurement. Representative transect stations were marked in the field with labelled with pink and orange surveyor's flagging. Measurements which were taken include: top width, bottom width, depth of channel (left bank and right bank), width and depth of water, and notation if flow was occurring at the observation point. A stream evaluation form for the USACE and NCDWR was prepared for a typical portion of the channel to observe and record channel characteristics and any special features associated with the chanel. Photographs were taken along the length of each channel. The location of all transects and channels were noted on a topographic base map of the site. Jurisdictional tributary channels were flagged with blue and white surveyor's flagging along both sides for an approximate distance of 100 feet. Each flag has a unique number and has been keyed to a sketch map of the site. e�ir�e / UESIGN • Post 0f{ice Box 163 0 H 9h Shoals 0 NC 0 28077 0 (704) 240-0793 References Site Base Topography and Boundary provided by Mecklenburg County Polaris 3G Geographic Information System (GIS) and Wirth and Associates.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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). ' Supporting documentation is presented in Section III.F. SECTION HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 102.0 acres Drainage area: 102.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: First to Second. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ® Natural ❑ Artificial (man-made). Explain: ❑ Manipulated (man -altered). Explain: Tributary properties with respect to top of bank (estimate): Average width: 22 feet Average depth: 9 feet Average side slopes: M.

Explain: the presence of litter and debris destruction of terrestrial vegetation the presence of wrack line sediment sorting scour multiple observed or predicted flow events abrupt change in plant community If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply): IN High Tide Line indicated by: E Mean High Water Mark indicated by: ❑ oil or scum line along shore objects ❑ survey to available datum; ❑ fine shell or debris deposits (foreshore) ❑ physical markings; ❑ physical markings/characteristics ❑ vegetation lines/changes in vegetation types. ❑ tidal gauges ❑ other (list): (iii) Chemical Characteristics: Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: Clear flow, good water quality. Identify specific pollutants, if known: 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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). ' Supporting documentation is presented in Section III.F. SECTION HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 187.0 acres Drainage area: 187.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: Second. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW.

Explain: Clear flow, good water quality. Identify specific pollutants, if known: 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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.

Non-regulated waters/wetlands (check if applicable):3 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: One Non-RPW Ephemeral Channel (Ditche) in upland (S-3) has been determined to be not jurisdicitional. ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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 HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 5.0 acres Drainage area: 5.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: First. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ❑ Natural ❑ Artificial (man-made). Explain: ® Manipulated (man -altered). Explain: Ditched. Tributary properties with respect to top of bank (estimate): Average width: 9 feet Average depth: 2 feet Average side slopes: M. Primary tributary substrate composition (check all that apply): ❑ Silts ❑ Sands ❑ Concrete ❑ Cobbles ❑ Gravel ❑ Muck ❑ Bedrock ® Vegetation. Type/% cover: herbaceous vegetation/75% 0 Other. Explain: natural soils based on test pit. Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: generally stable. Presence of run/riffle/pool complexes. Explain: Not present. Tributary geometry: Relatively straight Tributary gradient (approximate average slope): 1 % (c) Flow: Tributary provides for: Ephemeral flow Estimate average number of flow events in review area/year: Describe flow regime: stormwater driven ephemeral flow.

Explain: the presence of litter and debris destruction of terrestrial vegetation the presence of wrack line sediment sorting scour multiple observed or predicted flow events abrupt change in plant community If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply): IN High Tide Line indicated by: E Mean High Water Mark indicated by: ❑ oil or scum line along shore objects ❑ survey to available datum; ❑ fine shell or debris deposits (foreshore) ❑ physical markings; ❑ physical markings/characteristics ❑ vegetation lines/changes in vegetation types. ❑ tidal gauges ❑ other (list): (iii) Chemical Characteristics: Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: Does not exhibit characteristics of a natural stream channel, shallow trapezoidal cross section, straight alignment. No flow observed. Identify specific pollutants, if known: No pollutants known. 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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). ' Supporting documentation is presented in Section III.F. SECTION HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 102.0 acres Drainage area: 102.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: First to Second. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ® Natural ❑ Artificial (man-made). Explain: ❑ Manipulated (man -altered).

Explain: Clear flow, good water quality. Identify specific pollutants, if known: 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: N/A.

Non-regulated waters/wetlands (check if applicable):3 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: One Non-RPW Ephemeral Channel (Ditch) in upland (S-5) has been determined to be not jurisdicitional. ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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). ' Supporting documentation is presented in Section III.F. SECTION HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 5.0 acres Drainage area: 5.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: First. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ❑ Natural ❑ Artificial (man-made). Explain: ® Manipulated (man -altered). Explain: Ditched. Tributary properties with respect to top of bank (estimate): Average width: 10 feet Average depth: 3 feet Average side slopes: M. Primary tributary substrate composition (check all that apply): ❑ Silts ❑ Sands ❑ Concrete ❑ Cobbles ❑ Gravel ❑ Muck ❑ Bedrock ® Vegetation. Type/% cover: herbaceous vegetation/75% 0 Other.

Explain: Does not exhibit characteristics of a natural stream channel, shallow trapezoidal cross section, straight alignment. No flow observed. Identify specific pollutants, if known: No pollutants known. 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: N/A.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. 2 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). ' Supporting documentation is presented in Section III.F. SECTION HI: 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 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. 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 waterbody4 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.0 below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 173.0 acres Drainage area: 173.0 acres Average annual rainfall: 42 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through 2 tributaries before entering TNW. Project waters are 2-5 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 2-5 aerial (straight) miles from TNW. Project waters are 1 (or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: UT to West Branch to South Prong to Rocky River. Tributary stream order, if known: Second. ° Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. s Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ❑ Natural ❑ Artificial (man-made). Explain: ® Manipulated (man -altered). Explain: channelized.

Explain: Clear flow, good water quality. Identify specific pollutants, if known: 'A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) Summarize overall biological, chemical and physical functions being performed: C. 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. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: N/A.
