Our comments are submitted in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 -667d) and the Endangered Species Act of 1973, as amended (16 U.S.C. 1531 et seq.). The proposed project involves construction of approximately 9.8 miles of new greenway consisting of a 10- foot wide paved trail, 13 sections of new boardwalk, and 11 pedestrian bridges over low areas and unnamed tributaries, one pedestrian bridge over the Neuse River, one pedestrian bridge over Walnut Creek, and one pedestrian bridge over Crabtree Creek. Construction of the trail will involve clearing and grubbing, grading, placement of subgrade material and asphalt paving. The bridges over the Neuse River, Walnut Creek and Crabtree Creek will be constructed on 5.5 -foot diameter piers with boardwalk and graded approaches, as appropriate, and will not require any in- stream construction. There is an historical record of the federally endangered Dwarf wedgemussel (Alasmidonta heterodon) near the confluence of the Neuse River and Crabtree Creek, and the natural resources investigation documented that potentially suitable habitat exists for the Dwarf wedgemussel in the Neuse River, possibly where the crossings are proposed. However, since the project will have no direct stream impacts (i.e., no in- stream construction), the Service could concur with a "not likely to adversely affect" determination for the Dwarf wedgemussel. In addition, as mentioned in previous correspondence (Skycrest to Horseshoe segment, 06 Oct 2010), the Service would like to see the NC Wildlife Resources Commission's recommendations for porous pavement, maintaining buffers, avoiding impacts to streams and wetlands, and installing sediment and erosion control measures prior to land clearing or construction to be followed. These efforts will help to minimize impacts to aquatic and terrestrial resources. Thank you for your cooperation with our agency in protecting federally- listed species. If you have any questions or comments, please feel free to contact Sarah. McRae at (919) 856 - 4520x16.

We apologize for the delay in our response. The environmental report includes a preliminary cultural and archaeological resource assessment based on information in our files and some of our earlier correspondence with ESI, Inc. concerning the Neuse River Greenway. No actual field survey was conducted for archaeological resources. The report would have been much more useful if it had contained a map indicating the locations of the proposed greenway and the features discussed. Contrary to a statement in the report, documentation on archaeological sites 31WA1359 and 31WA1360 is not incomplete. Data recovery excavations were completed at both of these sites in connection with the North Carolina Department of Transportation Knightdale Bypass project. Copies of the resulting reports are on file at the Office of State Archaeology. As the environmental report was written in February 2010, it does not include our comments of July 27, 2010, requesting information regarding the size of the proposed parking lots and trailheads and a recommendation for archaeological survey and evaluation. It would also be helpful to know the regulatory requirements for this project. If permits are required from the US Army Corps of Engineers, have they defined the permit area and the area of potential effect (APE)? If there is federal involvement, the project will be subject to Section 106 of the National Historic Preservation Act. Please forward this information at your earliest convenience. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

Additional information is being provided related to sites specifically questioned in previous correspondence with NCSHPO. The project will require a nationwide 404 permit from the Army Corps of Engineers, as well as a 401 permit from Division of Water Quality. The permit area is approximately 20 feet wide for the entire length of trail (10 feet from edge of pavement on both sides of trail) and includes all jurisdictional waters crossed by the project. Federal funding is only associated with the Anderson Point to Skycrest Segment. No federal funding or involvement currently associated with the other segments of the project and it is not expected that those segments of the project will be subject to Section 106 of the National Historic Preservation Act. The initial project review was only related to the actual trail, and in a letter dated March 10, 2009 NCSHPO noted that the following sites may be affected by the greenway construction: 31WA27, 31WA214, 31WA519, and 31WA1617 (See Exhibit 1). As trail segments were finalized, more detailed information was sent to NCSHPO. These segments as reviewed are: 1. Anderson Point to Skycrest 2. Knightdale Connection 3. Wake Forest Connection 4. Skycrest 5. Johnston County to Anderson Point 6. Walnut Creek 7. Crabtree Creek A separate review of the Public Access Areas was completed, and in a letter dated July 27, 2010 NCSHPO noted that the following sites may be affected by the greenway construction: 31WA27, the last trailhead in Wake County (Mial Plantation Road), and 31WA1625. The letter also calls attention to site 31WA0288 which is the Hickory View Farm site. (See Exhibit 4) ENGINEERING. INNOVATION.

We apologize for the delay in our response, We have reviewed our snaps and files and offer the following comments. With regard to archaeological resources, the proposed 28 mile greenway contains various probabilities for the presence of archaeological resources. A long portion of the proposed greenway on the Raleigh East quadrangle map has already been surveyed prior to construction of a sewer line, as well as a portion of the greenway south of Milburnie to below US 64. Of the eleven recorded archaeological sites that may be affected by the greenway, four (31WA27, 31WA214, 31WA519 and 31WAl617) have not been evaluated for their eligibility for inclusion in the National Register of Historic Places. The remaining seven sites are either not eligible or have been the subject of data recovery excavations. There are also archaeological resources that may be appropriate for interpretation for users of the greenway. Brazier's 1820 map shows the locations of several fish weirs or traps and darns in Crabtree and Walnut Creeks and similar sites are known along the Neuse River. As plans regarding location, past ground disturbance and construction techniques become available, we recommend consultation with our office to determine if any recorded sites will be affected and if any archaeological survey should be conducted prior to greenway construction. We would also be glad to consult regarding opportunities for interpretation of the archaeological resources along the greenway corridor. As there are also many recorded structures or historic properties in the area, we would like the opportunity to review the final location of the greenway. The above comments are made pursuant to Section 106 of the National Historic Preseinration kct and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 Cl°lt Part 800.

The only recorded archaeological resources that may be affected by the proposed revisions are within the vicinity of Milburnie Dam. 31 WA27 is likely to be affected and site 31 WA1625 may also be affected by the proposed project. The proposed location of the last trailhead in Wake County has a high probability for the presence of as yet unrecorded archaeological sites. As noted in our letter of March 10, 2049, specific information regarding the size and dimensions of the proposed faralities and the amount of ground disturbing activities to be undertaken, would be helpful in making specific recommendations regarding appropriate archaeological investigations.

We apologize for the delay in our response. The environmental report includes a preliminary cultural and archaeological resource assessment based on information in our files and some of our earlier correspondence with ESI, Inc. concerning the Neuse River Cxreenway. No actual field survey was conducted for archaeological resources. The report would have been much more useful if it had contained a map Mi dicating the locations of the proposed greenway and the features discussed. Contrary to a statement in the report, documentation on archaeological sites 31WA1359 and 31WA1360 is not incomplete. Data recovery excavations were completed at both of these sites in connection with the North Carolina Department of Transportation Knightdale Bypass project. Copies of the resulting reports are on file at the Office of State Archaeology. As the environmental report was written in February 2010, it does not include our comments of July 27, 2010, requesting information regarding the size of the proposed parking lots and trailheads and a recommendation for archaeological survey and evaluation. It would also be helpful to know the regulatory requirements for this project. If permits are required from the US Army Corps of Engineers, have they defined the permit area and the area of potential effect (APE)? If there is federal involvement, the project will be subject to Section 106 of the National Historic Preservation Act. Please forward this information at your earliest convenience. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

We apologize for the delay in our response. In terms of archaeological resources, there are two areas of concern along this portion of the proposed greenway. As noted on your map, archaeological site 31 WA214 ** may be affected by the project. This site consists of both fish weirs or traps within the Neuse River as well as a possible mill and dam on land. We recommend an archaeological survey in this vicinity to ensure that the site will not be affected. If it cannot be avoided, the site should be evaluated for its eligibility for inclusion in the National Register of Historic Places. Not shown on your map is archaeological site 31 WA663 * *, the Griffis Mill Complex. This site is located away from the river adjacent to the Randleigh Farm property. The mill complex consists of the remains of a nineteenth century grist mill, tail race, head race, former mill pond, miller's house remains, a well and remains of another structure. This site is considered to be eligible for inclusion in the National Register of Historic Places. We recommend an archaeological survey in this vicinity to ensure that outlying features of the complex are not affected. If they cannot be avoided, appropriate mitigation treasures need to be developed in consultation with our office. In June, 2010, we received a request for review of proposed trailheads and parking lots for the Neuse River Greenway from Environmental Services, Inc. At that time, we recommended archaeological survey of the location of the last trailhead in Wake County as it has a high probability for the presence of archaeological sites. No parking lots or trailheads were identified on your project maps. If these elements are still part of the project, we repeat our recommendation for a survey of that area. We also requested information regarding the regulatory authority under which this greenway is being constructed. I£ a permit is required from the US Asny Corps of Engineers, the gteenway would be subject to Section 106 of the National Historic Preservation Act. If so, please forward information to us regarding the defused permit area and the defined area of potential effect (APE).

A list of archaeological consultants who have conducted or expressed an interest in contract work in North Carolina is available at www.arch.dcr.state.nc.us /consults.htm. The archaeologists listed, or any other experienced archaeologist, may be contacted to conduct the recommended survey. The trail, as proposed, will pass the Hickory View Farm (WA 0288), which is on the State Study hst—a preliminary step in the review of potential nominations to the National Register of Historic Places. This historic site is located on the west side of Brown Field Road (SR 2553), approximately 950 feet north of the intersection with Old Baucom Road (SR 5204). If this segment of the trial is built within the existing right-of- way of Brown Field Road, or if right -of -way is taken from properties on the east side of the road, the project will have no effect on the historic property. If any right -of -way taking is proposed for the Hickory View Farm property, please submit a site plan to our office for review and comment. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

We apologize for the delay in our response. Examination of our maps and files indicates that one of the proposed bridges may affect Atkins Fish Trap. Your letter mentions that cultural resource investigations, among others, were conducted to aid in the selection of the bridge locations. We request that you forward a copy of the cultural resource investigation for our information. If the preliminary work done by Environmental Services, Inc. is the referenced investigation, it consisted of a literature search as no archaeological field survey was involved. Information in their report was taken primarily from our maps and files. You should note that archaeological sites 31 WA1359 and 31 WA1360 identified on your map as eligible for the National Register have been subjected to data recovery excavations as they were adversely affected by the construction of the Krsightdale Bypass by the North Carolina Department of Transportation. There are areas of the Crabtree Creek Segment that may contain archaeological resources. It would be helpful if you could forward information as to the regulatory requirements for the trail. Will permits be required from the US Army Corps of Engineers? If so, what is the defined permit area and the area of potential effect (APE)? If the project requires federal permits and is subject to Section 106 of the National Historic Preservation Act, we may recommend archaeological survey of portions of the project. We would appreciate receiving a copy of the cultural resource investigation report as well as detailed mapping, if available, of the trail in the vicinity of Atkins Fish Trap so we may determine if it will be affected and what mitigation measures may be appropriate. We have determined that the project as proposed will not have an effect on any historic structures.

We apologize for the delay in our response. Examination of our maps and files indicates that one of the proposed bridges may affect Atkins Fish Trap. Your letter mentions that cultural resource investigations, among others, were conducted to aid in the selection of the bridge locations. We request that you forward a copy of the cultural resource investigation for our information. If the preliminary work done by Environmental Services, Inc. is the referenced investigation, it consisted of a literature search as no archaeological field survey was involved. Information in their report was taken primarily from our maps and files. You should note that archaeological sites 31WA1359 and 31WA1360 identified on your map as eligible for the National Register have been subjected to data recovery excavations as they were adversely affected by the construction of the Knightdale Bypass by the North Carolina Department of Transportation. There are areas of the Crabtree Creek Segment that may contain archaeological resources. It would be helpful if you could forward information as to the regulatory requirements for the trail. Will permits be required from the US Army Corps of Engineers? If so, what is the defined permit area and the area of potential effect (APE)? If the project requires federal permits and is subject to Section 106 of the National Historic Preservation Act, we may recommend archaeological survey of portions of the project. We would appreciate receiving a copy of the cultural resource investigation report as well as detailed mapping, if available, of the trail in the vicinity of Atkins Fish Trap so we may determine if it will be affected and what mitigation measures may be appropriate. We have determined that the project as proposed will not have an effect on any historic structures.

We appreciate your meeting with staff of the Office of State Archaeology to clarify project plans. We have reviewed the accompanying maps, plans and aerial photographs and offer the following comments. While the fish trap portions of archaeological site 31WA214 ** will not be affected by the proposed greenway, the possible mill and dam portions of the site may be affected. We recommend that the area of the greenway in the vicinity of 31WA214 ** be surveyed by an experienced professional archaeologist. If portions of the site will be affected, it should be evaluated for its eligibility for inclusion in the National Register of Historic Places. The Mial Plantation Trailhead should be surveyed by an experienced professional archaeologist, as there is a high probability for the presence of archaeological resources. Monitoring by an experienced professional archaeologist should be undertaken in the vicinity of archaeological site 31 WA27 to ensure that no significant archaeological resources are affected by the project. The east side of the river in the area of archaeological site 31WA1617 should be surveyed by an experienced professional archaeologist. If portions of the site will be affected, it should be evaluated for its eligibility for inclusion in the National Register of Historic Places. Based on examination of the project plans, maps and aerial photographs, we concur with your assessment that archaeological sites 31 WA519, 31 WA1625, 31 WA663 ** and the Atkins Fish Trap are outside the area of impact or have been destroyed by past activities. We withdraw our earlier recommendations for archaeological investigations in these areas. Two copies of the resulting archaeological survey report, as well as one copy of the appropriate site forms, should be forwarded to us for review and comment as soon as they are submitted by the consulting archaeologist and well in advance of any construction activities.

The archaeologists listed, or any other experienced archaeologist, may be contacted to conduct the recommended survey. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

At your request, ESI has conducted a natural resources investigation including a wetland/stream delineation, Neuse River riparian buffer rules review, a threatened and endangered species habitat evaluation, and a preliminary cultural and archaeological resource assessment on the approximately 27.4 - mile Lower Neuse Greenway project in Wake County, North Carolina. This letter report serves as the deliverable for this project. The project includes a proposed greenway along the Neuse River from the Wake/Johnston County Line to the Horseshoe Farm Park (north of US 401) (Figure 1) and includes additional greenways along Crabtree Creek and Walnut Creek. The project study area is approximately 1,000 acres (ac) in areal extent, encompassing a corridor approximately 27.4 miles [144,672 feet (ft)] in length and ranges fi-om 120 to 300 ft in width. Prior to the initiation of field efforts, available resources were reviewed, including the appropriate U.S. Geologic Survey (USGS) 7.5- minute topographic quadrangles (Clayton, NC, Garner, NC, Knightdale, NC, Raleigh East, NC, Rolesville, NC and Wake Forest, NC), Soil Survey for Wake County, and North Carolina Natural Heritage Program (NHP) database. The project is broken into seven sections (1 -7). Below is a brief description of each section. Section 1— This section begins at the Wake/Johnston County Line on the north side of the Neuse River and extends approximately 1.5 miles `vest where it crosses to the southwest side of the Neuse River. At this point, the proposed trail breaks away from the Neuse River for approximately 3 A miles, then runs west and then north to avoid the existing City of Raleigh Wastewater Treatment Plant Facility, and returns to the south side of the Neuse River, cast of Auburn- Knightdale Road (SR 2555). Section 1 ends approximately 500 ft north of Auburn - Knightdale Road. Section I is approximately 5.8 miles long, has a project study area width of 300 ft, and includes one bridge crossing over the Neuse River. FLORIDA • GEORGIA • NORTH CAROLINA • SOUTH CAROLINA • MARYLAND • OHIO ENVIRONMENTAL, SERVICES, INC. Page 2 of 14 Lower Neuse Greenway February 2010 Section 2 -- This section begins at the terminus of Section 1, approximately 500 ft north of Auburn - Knightdale Road, and extends north along the west side of the Neuse River to Poole Road (SR 1007). Section 2 is approximately 2.7 miles long, has a project study area width of 300 ft, and includes one bridge crossing of Walnut Creek. Section 3 — This section begins at the terminus of Section 2 on the north side of Poole Road and extends north along the west side of the Neuse River to the south side of Crabtree Creek and the southern boundary of Anderson Point Park. Section 3 is approximately 1.1 miles long, has a project study area width of 300 ft, and includes one bridge crossing of Crabtree Creek. Section 4 — This section begins at the terminus of Section 3 along the southern boundary of Anderson Point Park at Crabtree Creek and extends north along the west side of the Neuse River along an existing gravel trail to the future Skycrest Road {just north of the Hedingham Subdivision). Section 4 is approximately 3.3 miles long and has a project study area width of 120 ft (60 ft centered on the existing gravel trail). There are no Neuse River bridge crossings associated with Section 4 at this time. Bridges Lake has an existing wooden bridge that will be utilized. Section 5 — This section begins at the terminus of Section 4 on the north side of the future Skycrest Road, crosses to the east side of the Neuse River and extends north along the east side of the Neuse River for approximately 1.7 miles and then crosses to the west side of the Neuse River near the Buffalo Road Athletic Park. The proposed trail continues north along the west side of the Neuse River to Horseshoe Farm Park. Section 5 is approximately 6.9 miles long and has a project study area width of 300 ft. Section 5 includes a total of four bridge crossings of the Neuse River, including two bridge crossings associated with connecting the proposed trail with Horseshoe Farm Park. Section 6 — This section begins approximately 300 ft west of the confluence of Walnut Creek and the Neuse River (in Section 2) and extends along the south side of Walnut Creek for 0.75 mile before crossing to the north side of Walnut Creek. Section 6 continues west along the north side of Walnut Creek through the existing Walnut Creek Softball Complex and ends at the existing Worthdale Park. Section 6 is approximately 3.7 miles long and has a project study area width of 300 ft. Section 6 includes one bridge crossing of Walnut Creek. ENVIRONMENTAL SERVICES, INC. Page 3 of 14 Lower Neuse Greenway February 2010 Section 7 — This section begins along the western boundary of Anderson Point Park and extends west approximately 1,000 feet where it then crosses to the southwest side of Crabtree Creek. Section 7 continues west approximately 1.3 miles along the south side of Crabtree Creek before crossing to the north side of Crabtree Creek, then continues west along the north side of Crabtree Creek to the west side of New Bern Avenue (US 64 Business). Approximately 2,000 ft west of New Bern Avenue the proposed trail crosses to the west/south side of Crabtree Creek and ties into the existing Buckeye Trail. Section 7 is approximately 33 miles long and has a project study area width of 300 ft. Section 7 includes three bridge crossings of Crabtree Creek. Staff Experience The project study area `vas reviewed from January through December 2009 by ESI biologists Gail Tyner, Kevin Markham, Robert Turnbull, Katie Tomany, Todd Milam, and Charles Johnston. Ms. Tyner is a Senior Scientist with more than 11 years of professional experience. Mr. Markham is a Senior Scientist and Regional Division Director with more than 21 years of professional experience. Mr. Markham holds state and federal permits for in- stream dwarf wedgemussel surveys and was responsible for the dwarf wedgemusel habitat evaluation.

Mr. Milam is a Project Scientist with more than five years of professional experience. Mr. Johnston is a Senior Scientist with more than four years of professional experience, Water Resources The project study area is located within the Neuse River drainage basin. There are four named streams within the project study area [the Neuse River, Bridges Creek (Bridges Lake), Crabtree Creek, and Walnut Creek]. The Neuse River has been assigned Stream Index Number (SIN) 27- (22.5) and 27 -(36) within the project study area. The Neuse River [SIN 27- (22.5)], from the Town of Wake Forest proposed water supply intake to the mouth of Beddingfield Creek, has a Best Usage Classification (BUC) of C;NSW. The portion of the Neuse River, from the mouth of Beddingfield Creek to a point 0.2 mile downstream of Johnston County SR 1700 [S1N 27- (36)], has a BUC of WS -V; NSW. The portions of Bridges Creek (Bridges Lake) (SIN 27 -30), Crabtree Creek [SIN 27- 33- (10)], and Walnut Creek [SIN 27- 34-(4)] within the project study area have a BUC of C; NSW. Class C waters are protected for secondary recreation, fishing, aquatic Iife (including propagation and survival), and wildlife. Secondary recreation is any activity involving human body contact with water on an infrequent or incidental basis. The supplemental classification NSW indicates Nutrient Sensitive Waters, which require limitations on nutrient inputs. Class WS -V waters are waters protected as water supplies which are generally upstream of and drain to Class WS -)[V waters; or previously used for drinking water supply purposes or waters used by industry to supply their employees with a raw drinking water source. Class WS -IV waters are ENVIRONMENTAL SERVICES, INC. Page 4 of 14 Lower Neuse Greenway February 2010 waters protected as water supplies, which are generally in moderately to highly developed watersheds. Point source discharges of treated wastewater are permitted pursuant to Rules .0104 and .0211 of T15A;02BA100. Local programs to control nonpoint source and stormwater discharges of pollution are required and these waters are suitable for all Class C uses, Plant Communities Dominant community types within the project study area consist of a Piedmont/Mountain Levee Forest and disturbed successional communities associated with utility corridors. Typical overstory vegetation observed within the Piedmont/Mountain Levee Forest community includes box elder (Ater negundo), American sycamore (Platanus occidentalis), hackberry (Celtis laevigata), river birch (Betula nigra), green ash (Fraxinus pennsylvanica), and musclewood (Carpinus caroliniana). Typical understory species observed within this community includes American. elm (Ulmus americana), slippery elm (Uhnus rubra), spice bush (Lindera benzoin), buckeye (Aesculus sylvatica), giant cane (Arundinaria gigantea), river oats (Chasmanthium latifolium), and poison ivy (Toxicodend)-on radicans). The vegetation within the utility corridors includes successional species such as lespedeza (Lespedeza sp.) and dog fennel (Eupatoriuni sp.)

N.C. Division of Water Quality (NCD.WQ) and USACE standards were used to determine the presence or absence of jurisdictional streams and jurisdictional surface waters within the project study area. The jurisdictional delineation was reviewed by the NCDWQ for Neuse River Riparian Buffer Applicability (March 24 and July 15 and 16, 2009). As of the date of this report, the jurisdictional delineation has not been reviewed by the USACE, although ESI has asked the USACE on several occasions to consider a site visit. There are 88 jurisdictional stream channels (including the Neuse River, Crabtree Creek, and Walnut Creek), nine jurisdictional ponds, and 104 jurisdictional wetland areas located within the project study area (Figures 3a -m and Tables B -1 and B -2 in Appendix B). The jurisdictional areas within each section are designated with a corresponding letter sequence (i.e„ a wetland in Section 1 is labeled as WAl and a ENVIRONMENTAL SERVICES, INC. Page 6 of 14 Lower Neuse Greenway February 2010 stream feature in Section 2 is labeled as SB1). Figures 3a -m depict the general layout of the jurisdictional features within the project study area. Characteristics of each jurisdictional feature within each section are included in Tables B -1 and B -2. To more accurately depict the amount of jurisdictional areas within the project study area that could be impacted, EST did not include the linear extent of the three (3) major stream features (the Neuse River, Crabtree Creek, and Walnut Creek), but provided stream widths at proposed trail crossings [Bridge Crossings (BC)]. Excluding bridge crossings of the Neuse River, Walnut Creek, and Crabtree Creek, there are 61 other perennial streams which account for 19,746 linear ft and 24 intermittent streams which account for 4,413 linear ft of stream channel within the project study area. There are approximately 63.6 ac of wetlands and 1.6 ac of jurisdictional ponds within the project study area. Riparian Buffer Rules Review The project study area is within the Neuse River basin and is subject to the Neuse River Riparian Buffer Rules. The riparian buffer consists of two distinct zones. Zone 1 comprises a 30 -ft wide area adjacent to the surface water that cannot be disturbed except for those specific activities that are allowed by the Buffer Rules. Zone 2 comprises a 20 -ft wide area adjacent to Zone 1 that is to be left undisturbed except for those activities specifically allowed by the Buffer Rules. All of the features depicted on either the most recent versions of the USGS topographic quadrangle or the Wake County Soil Survey maps are subject to riparian buffer rules, unless an exemption has been obtained from the NCDWQ. Table 2 provides information on which streams are subject to Buffer Rules. Activities in the buffer area beyond the footprint of the existing use are classified as either "exempt ", "allowable ", "allowable with mitigation ", or "prohibited" Based on an August 18, 2006 letter concerning the Upper Neuse Greenway and published guidance from NCDWQ, greenway trails (Appendix C) are considered an "allowable" activity within the buffers, but written NCDWQ notification will be required. In addition, the greenway trails should be outside the 50 -ft buffer where possible, should stay within Zone 2 as much as practicable, and stream crossings should be constructed as near perpendicular as possible. "Allowable" activities may proceed within the riparian buffer provided that there are no practicable alternatives to the requested use. Prior to initiating impacts, written authorization from the NCDWQ or delegated local authority is required. ENVIRONMENTAL SERVICES, INC. Page 7 of 14 Lower Neuse Green-way February 2010 During the NCDWQ buffer review, ESI focused on reviewing features that were depicted on the USGS and/or the Wake County soils mapping as stream features, but were not flagged as jurisdictional or the entire feature was flagged as a wetland by ESI. Below is a summary of the Neuse River Riparian Applicability for Lower Neuse Greenway. WA6, WA12, WD16, WD18i, WEB, and WGI are depicted on the most recent version of the appropriate USGS topographic quadrangle and/or the Wake County soils mapping as stream features; however, ESI flagged these features as wetlands (Figures 3a -m). These features have been reviewed by NCDWQ and were determined to be subject to the Neuse River Riparian Buffer Rules because they were impounded stream channels. WD13, WD18a, WE4, WE5, WE15, WE18, WG6, WG7, and WG8 are depicted on the most recent version of the appropriate USGS topographic quadrangle and/or the Wake County soils mapping as stream features, however ESI flagged these features as wetlands (Figures 3a -m). These features have been reviewed by NCDWQ and determined not to be subject to the Neuse River Riparian Buffer Rules. SA4, SA12, SA17, SCl, SC3, SDI, SD3, SDS, SD8, SD10, SD13, SE9, SE13, and SF2 are not depicted on the most recent version of the appropriate USGS topographic quadrangle or the Wake County soils mapping and therefore are not subject to the Neuse River Riparian Buffer Rules. SF3, SF8, SF16, and SF18 are considered oxbows or outer braids of Walnut Creek and are subject to the Neuse River Riparian Buffer Rules even though the specific feature may not be mapped. WA8, WAIO, WB4, WF5, WF6, WF10 and WFI 8 were not specifically reviewed by NCDWQ for Neuse River Riparian Buffer Applicability. These features are depicted as streams on the appropriate USGS and/or the Wake County soils mapping, therefore subject to the Neuse River Riparian Buffer Rules. ESI flagged portions of these features as streams, but not to the extent shown on the USGS and/or soils mapping. If the proposed trail is located within or within 50 ft of these features, NCDWQ can make a final determination on riparian buffer applicability. The remaining streams within and/or within 50 ft of the project study area depicted on the most recent version of the appropriate USGS topographic quadrangle and/or the Wake County soils mapping are subject to the Neuse River Riparian Buffer Rules. ENVIRONMENTAL SERVICES, INC. Page 8 of 14 Lower Neuse Greenway February 2010 Inland Primaa Nursea Areas Portions of Neuse River within the project study area have been designated as an Inland Primary Nursery Area (IPNA) by the N.C. Wildlife Resource Commission. According to the USACE Special Designated Streams and Waters, IPNAs include 10,000 acres of Inland Fishing Waters in the coastal areas, as well as portions of the four main rivers (Roanoke River, Tar - Pamlico River, Neuse River, and Cape Fear River) draining to North Carolina's coast. The Neuse River from Pitchkettle Creek in Craven County to Milburnie Dam in Wake County is considered to be an Inland Primary Nursery Area. IPNAs are subject to a moratorium on in- stream work from February to October. Coordination with WRC will be required. WRC does not typically grant pre - construction variances for the in- stream work moratorium. However, WRC has the discretion to grant variances, on a case by case basis, at the beginning or end of the moratorium when the potential impacts to the IPNA and the affected species can be accurately evaluated. Threatened and Endangered Species Evaluation ESI evaluated the project study area for potential habitat for federally Threatened (T), Endangered (E), or otherwise protected species known to have ranges extending into Wake County, NC (January 25, 2010 USFWS website list). The U.S. Fish and Wildlife Service ( USFWS) lists four species with federal protection that have ranges extending into Wake County: bald eagle (Haliaeetus leucocephalus), red - cockaded woodpecker (Picoides borealis), dwarf wedgemussel (Alasmidonta heterodon), and Michaux's sumac (Rhus michauxii). The bald eagle is protected by the Bald and Golden Eagle Protection Act (BGEPA) and the Migratory Bird Treaty Act (MBTA). The other three species are protected under the Endangered Species Act (ESA). Records held by the North Carolina Natural Heritage Program (NHP) were reviewed on January 25, 2010 to determine if any of these species have been recorded on or within 1.0 mile of the project study area. A description and review of the project study area for potential habitat for each of the federally listed species is discussed below. Bald eagle (BGEPA/MBTA-protected) typically nest in tall, living trees in a conspicuous location near water and forage over large bodies of water with adjacent trees available for perching. The bald eagle was officially delisted and removed from the federal Endangered Species List on August 9, 2007, but they are still protected under the BGEPA and the MBTA. NIP records review indicates no documented nest sites within 1.0 mile of the project study area. Marginal foraging and roosting habitat for this species exists within the project study area along the Neuse River. On June 22, 2009, ESI biologists Robert Turnbull, Katie Tomany, Todd Milam and Charlie Johnston canoed the Neusc River and visually surveyed along the Neuse River for bald eagle nests, no nests or individuals were observed. The project should not affect bald eagle. Biological Conclusion: Not Required ENVIRONMENTAL SERVICES, INC. Page 9 of 14 Lower Neuse Greenway February 2010 Red - cockaded woodpecker (E) is a small woodpecker that nests primarily in open pine stands greater than 60 years old with little or no mid -story development. Foraging habitat is comprised of open pine or pine /mixed hardwood stands greater than 30 years old. Primary habitat consists of mature to over - mature southern pine forests dominated by loblolly (Pines taeda), longleaf (Pinus palustris), slash (Pinus elliotfl), and pond pines (Pinus sei,oflna). These pine stands must generally be a minimum of 10 ac in size. Development of a thick understory may result in abandonment of cavity trees. Mixed pine/hardwood communities within the project study area are hardwood dominated and would not be considered suitable nesting or foraging habitat. NBP records review indicates no document occurrences of this species within 1.0 mile of the project study area. Potential habitat for this species does not exist within the project study area. Biological Conclusion: No Effect, Dwarf wedgemussel (E) typically inhabits perennial streams with slow to moderate current, good water quality with little siltation, and with stable banks and substrate. Within these areas, dwarf wedgemussels are typically found along root mats, around logs, and under overhangs or other relatively protected microhabitats. Streams within the project study area were reviewed on June 3 and 9, 2009 by EST biologists Kevin Markham and Todd Milam. Most of the streams within the project study area were determined to not provide suitable habitat for dwarf wedgemussel. The unnamed tributaries within the project study area are generally too small and do not contain suitable substrate. The reaches of Crabtree Creek and Walnut Creek within the project study area exhibited substrate characterized by relatively extensive deposits of unconsolidated sediment, with stream banks exhibiting relatively extensive scour with erosion noted extending upstream and downstream from the project study area. The Neuse River may provide potentially suitable habitat within the project study area. Relatively stable streambanks and potential microhabitat areas including root mats, logs, and areas of clay to fine sand substrate were identified within the Neuse River within the project study area. No evidence of any native mussel fauna (relict shells) was observed along stream banks or scan of stream beds; relict shells of the exotic, introduced Asiatic clam (Corbicula flinninea) were observed within the streambed and along the banks of the Neuse River. A review of NBP records indicates that no extant occurrences of the dwarf wedgemusssel are documented within 1.0 mile of the project study area. There is an historic record of dwarf wedgemussel documented within the Neuse River from the vicinity of Poole Road; NBT represents the general location for this historic occurrence as the reach from approximately New Bern Avenue to Walnut Creek. This historic occurrence locale was searched extensively in the mid - 1980s as part of the USFWS status survey for the species prior to listing the species as Endangered; the results of those surveys led to the USFWS conclusion that the species had been extirpated from the Neuse River. ENVIRONMENTAL SERVICES, INC. Page 10 of 14 Lower Neuse Greenway February 2010 If there were no direct stream impacts (f. e., in- stream work or in- stream structures) proposed for this project, then there should be no adverse effects to dwarf wedgemussel populations. However, because potentially suitable habitat was identified within the Neuse River, and Neuse River crossings are proposed, species specific surveys may be requested by the USIi WS to ensure dwarf wedgemussel is not present within the project footprint before a determination of effects can be made. Biological Conclusion: Unresolved Michaux's sumac (E) tends to grow in disturbed areas where competition is reduced by periodic fire or other disturbances and may grow along roadside margins or utility easements. Michaux's sumac appears to prefer sandy or rocky substrates consisting of basic soils. The majority of the project study area would not be considered potentially suitable habitat for this species due to the forested canopy and thick shrub layers in successional areas. Potential habitat consisting of open edge areas is present within the project study area. NHP records review indicate one documented occurrence of this species approximately 1,200 feet south of Walnut Creek adjacent to Barwell Road and one documented occurrence approximately 1.0 mile east of the Neuse River near the intersection of US 64 Business and I -540. Prior to field investigations, ESI biologists Katie Tomany, Robert Turnbull, and Todd Milam visited the above referenced Michaux's sumac population in on Barwell Road prior to conducting surveys to confirm vegetative status. During the spring of 2009, surveys were conducted for this species within the potential habitat including utility corridor edges, trails, and roadsides. No individuals were observed during pedestrian surveys through potential habitat in the project study area. No impacts to Michaux's sumac populations are anticipated as a result of this project. Biological Conclusion; No Effect. Preliminary Cultural and Archaeological Resource Assessment A representative of ESI conducted research at the Office of State Archaeology (OSA) and the Survey and Planning Branch (SPB) of the North Carolina State Historic Preservation Office (SHPO) on 27 January 2009. The purpose of the research was to identify recorded cultural resources in and in the vicinity of the proposed trail, This research revealed the presence of six recorded historic structures, 18 archaeological sites, a possible mill site, and four fish trapsiwiers (see Tables 2, 3, and 4).

Page 12 of 14 Lower Neuse Greenway February 2010 None of the six recorded historic structures are listed in, eligible for listing in, or potentially eligible for listing in the National Register of Historic Places (National Register). The "Mill Site," which is shown on the maps at the SPB does not pertain to a standing structure. The four fish traps/weirs are all unassessed regarding their National Register eligibility. Eight of the archaeological sites are not eligible for the National Register, the eligibility status for six has not been assessed, the eligibility status of one is unknown, and three have been determined eligible for listing in the National Register. Of the three National Register eligible archaeological sites, site 31WA1137 is located on the north bank of the Neuse River at the crossing by US 401. It is opposite the proposed greenway corridor and would not be affected by the greenway project as currently proposed. Sites 31WA1359 and 31WA1360 were located within the ROW for the US 64 Knightdale Bypass. It is possible that neither site still exists, but documentation at the OSA is incomplete. Of the six unassessed archaeological sites, one is outside the proposed greenway corridor and would not be affected by the greenway project as currently proposed. Five of the sites, sites 31 WA574, 31WA519, 31WA214, 31WA27, 31WA1617, are located within the proposed greenway corridor and could potentially be affected by the greenway project as currently proposed. Although the National Register eligibility status of 31WA1625 is unknown, the site is located across the river from the proposed greenway corridor and would not be affected by the greenway project as currently proposed. ESI submitted a coordination letter to the SHPO on 28 January 2009 requesting comment on the proposed project. In a letter dated 10 March 2009, the SHPO stated that four sites (31WA27, 31WA214, 31 WA519, and 31 WA1617) could be affected by the proposed greenway and have not been evaluated for their National Register eligibility. Additionally, the SHPO stated that there are archaeological resources that may be appropriate for interpretation, and specifically noted the 1820 Brazier Map showing the locations of fish weirs or traps and dams along Crabtree and Walnut creeks, and that similar sites are known along the Neuse River, The SETO requested additional consultation once more information on past ground disturbance and construction techniques is available in order to determine if any recorded archaeological sites would be affected and if any archaeological survey should be conducted. The SBPO also offered assistance regarding opportunities for interpretation of archaeological resources along the proposed corridor. ENVIRONMENTAL SERVICES, INC. Page 13 of 14 Lower Neuse Greenway February 2010 Summary The jurisdictional features within the project study area have been delineated and the attached graphics indicate their general layout (Figures 3a -m). This general layout is not a substitute for a traditional survey and is not a legal or recordable document. There are 88 jurisdictional stream channels (including the Neuse River, Crabtree Creek, and Walnut Creek), nine jurisdictional ponds, and 104 jurisdictional wetland areas located within the project study area. Excluding bridge crossings, there are 61 other perennial streams which account for 19,746 linear ft and 24 intermittent streams which account for 4,413 linear ft of stream channel within the project study area. There are approximately 63.6 ac of wetlands and 1.6 ac of jurisdictional ponds within the project study area. The project study area is subject to the Neuse River Riparian Buffer Rules. There are both buffered and un- buffered features within the project study area. Please refer to Tables B -1 and B -2 in Appendix A for details on the applicability of the Neuse River Riparian Buffer Rules for each feature. NIP records review did not document any known current occurrences of state or federally protected species within the project study area. The project study area lacks potential habitat for the federally protected red - cockaded woodpecker. The project study area contains potential habitat for bald eagle, dwarf wedgemussel, and Michaux's sumac. The project should have no adverse affect on bald eagle populations. No impacts to Michaux's sumac populations are anticipated as a result of this project. Potentially suitable habitat for dwarf wedgemussel within the project study area is limited to the Neuse River. Additional coordination with USFWS may be required. The USFWS may request surveys be conducted within the project footprint before a determination of effects can be made. The SHPO has requested that additional consultation with their office be conducted to determine if any of the unassessed, previously recorded archaeological sites will be impacted by the proposed greenway and if any stretch of the proposed greenway will need an intensive archaeological survey. Additionally, the SHPO has requested additional consultation regarding historic structures once the final location of the greenway has been determined. ENVIRONMENTAL SERVICES, INC.

Hauser, AICP Stewart Engineering 260 Town Hall Drive — Suite C Morrisville, NC 27560 Michael F. Easley, Governor William G. Ross Jr., Secretary North Carolina Department of Environment and Natural Resources August 18, 2006 Reference: The Upper Neuse Greenway Trail Raleigh, Wake County, NC Dear Ms. Hauser: Alan W. Klimek, P.E. Director Colleen H, Sullins, Deputy Director Division of Water Quality As per our phone conversation on August 15, 2006 and a Request for Comments dated August 9, 2006 forwarded to the Raleigh Regional Office, you requested input on the proposed eight -mile greenway trail, which will extend from the foot of the Falls Lake dam to the WRAL Soccer Complex on Perry Creek Road. DWQ Raleigh Regional Office comments on the proposed project are as follows: 1) All streams within the project corridor that are shown on either the most recent version of the USGS topographic maps or the USDA Soil Survey of Wake County are subject to the Neuse River Riparian Buffer Rules. Greenway trails are considered an "Allowable" activity within the buffers, 2) As we discussed, the intent of the project is to construct the greenway trail outside the 50- foot riparian buffers where possible. DWQ requests that where the trail will be located within the buffer, efforts should be made to site the trail within Zone 2 (outer 20 feet) unless site conditions (topography, etc.) render this impractical.. 3) Where the greenway trail is to cross tributaries, the crossings should be constructed as near perpendicular as possible (between 75 and 105 degrees). 4) Stream and wetland crossings are subject to 401 Water Quality Certification requirements. Please note that GC 3402 requires notification for any impacts to any stream length within the Neuse River Basin unless the activities are listed as Exempt" under the buffer rules. Since greenway trails are listed as "Allowable" written notification to DWQ will be required. 5) Where stream crossings will involve bridges, buffer authorization will still be required. 401 Water Quality Certification will not be required for these crossings if no channel impacts will occur. Please note that additional comments may be made following review of Pre- Construction Notifications, buffer authorization requests, or other permitting documents.

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 TN1V) 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 Ieast 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, slip to Section M.D.4. A wetiand that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbodya is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B3 for all wetlands adjacent to that tributary, both onsite and offslte. 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:'tek Ltsf Drainage area: Pick List Average annual rainfall: 46.4 inches Average annual snowfall: 5.6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ® Tributary flows directly into TNW. ❑ Tributary flows through lick Lisf tributaries before entering TNW.

Explain: water is clear. Identify specific pollutants, if known: 6A natural or man-made discontinuity in the OHIVM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHNVM 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? (YIN) 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 TN%V. 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 MV? • 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: L Significant nexus findings for non -RPW that has no adjacent wetlands and flows directly or indirectly into TNWs.

If the aquatic resource is a TNW, complete Section HI.A.1 and Section M.D.J. only; if the aquatic resource is a wetland adjacent to a. TNW, complete Sections HI.A.1 and 2 and Section III.D.1.; otherwise, see Section IH.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 11I,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 IH.0 below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and /or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNN, 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?

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, ship to Section HI.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, slip 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 111,11.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section I11.113 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section HI.0 below. 1.

SECTION III: CWA ANALYSIS 7 A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TN`Vs and wetlands adjacent to TNWs. If the aquatic resource is a TNNV, complete Section III.A.1 and Section fII.D.f. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections III.A.1 and 2 and Section HI.D.I.; otherwise, see Section III.B below. 1.

CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNPV) 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 Rapnnos 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 HI.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section IH.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 HI.B.2 for any onsite wetlands, and Section 1H.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section IILC below. 1.

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 TN-V. 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 theRgpanos 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 TN W? • 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.

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 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 covers a tributary with adjacent wetlands, complete Section III.11.1 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 M.0 below. I.

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 wetiand 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 TNNVs, 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 lifecyele 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?

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 IH.D.I, 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.

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 RapaDoshave 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 HI.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 offslte. The determination whether a significant nexus exists is determined in Section M.0 below. . 1.

Explain: 1 Boxes checked below shall be supported by completing the appropriate sections in Section III below. z For purposes of this form, an RPW is defined as a tributary that is not a'1NW and that typically flows year -round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. SECTION III . CWA ANALYSIS J;p,,�, 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 TN_NV, complete Section III.A.1 and Section III.D.I. 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 1111.13 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, slip 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 (arid 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 HI.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.

Explain: Identify specific pollutants, if known: 6A natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the 0IIWM has been removed by development or agricultural practices). Where there is a break in the 0HWM that is unrelated to the Nvaterbody'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. 7Ibid.

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 theRapanos 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.

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 TN%Vs 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.BA for the tributary, Section HI.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-TN-Ws that flow directly or indirectly into TNW (i) General Area Conditions Watershed size: PfckLis Drainage area: �l?lek Ljsf Average annual rainfall: inches Average annual snowfall: inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ❑ Tributary flows through 'tek ItS tributaries before entering TNW.

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 TNVY. 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 TNVV. 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 TNNV, 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 fioodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TN V, 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 (i€ 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 an}), 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 MV? 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: t Boxes checked below shall be supported by completing the appropriate sections in Section III below. a 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 III: CWA ANALYSIS l ' A. TN-IVs 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 HI.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 IH.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 HI.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 covers a tributary with adjacent wetlands, complete Section HI.B.1 for the tributary, Section HI.B,2 for any onsite wetlands, and Section IH.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section HI.0 below. 1.

Explain: Boxes checked below shall be supported by completing the appropriate sections in Section III below. Z For purposes of this form, an RPW is defined as a tributary that is not a TNVV and that typically flows year -round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F, SECTION III: CWA ANALYSIS A. TNWs AND EETLANDS 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.AA and Section IiI.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections M.A.1 and 2 and Section III.D.I.; otherwise, see Section IH.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2, Wetland adjacent to TNVV 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 111,19.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section 1II.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 I11.B.1 for the tributary, Section HI '.B.2 for any onsite wetlands, and Section IH.B,3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section I11.0 below. 1.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and /or biological integrity of a TMV. 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 TN%Vs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: Significant nexus findings for non -RPW and its adjacent wetlands, where the non -RPW flows directly or indirectly into TN1Vs.

Channel sinuosity: Straight Occasional bends Frequent meander Very sinuous Braided channel Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the characteristics identified in the Worksheet. Scores should reflect an overall assessment of the stream -reach under evaluation. If a characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the highest quality. I Total Score (from reverse): _ 6V . Comments: Evaluator's Signature Date ' This channel evaluation' rm is intended to be used y as a guide to assist landowners and environ ental profissionals in gathering the data required by the United States AKny Corps of Engineers to make a preUminaq assessment of stream quality.
