February 22, 2010 Copies of this PCN, along with a check for the processing fee, are being provided to DWQ for written concurrence in accordance with Water Quality Cert ification No. 3687. BACKGROUND INFORMATION The project area is located behind commercial businesses at 5007 and 5009 Monroe Road, upstream of a 5' by 3' elliptical culvert that drains under the parking lot of the Lake Hill Apartment Complex. The southwest portion of the project area is bordered by maintained lawn and a parking lot located behind commercial properties on Monroe Road. To the east, the project is bounded by a small wooded lot and the Oakhurst Baptist Church and its parking lot located on Eaton Street. The upstream watershed consists of commercial properties located on Monroe road as well as adjacent residential properties. The location of the project area is depicted on the Site Vicinity Map (Figure 1), the appropriate portions of the Charlotte East. N.C (1991) USGS Topographic Map (Figure 2), and a 2009 Aerial Photograph (Figure 3). In 2005 CSWS retrofitted Shade Valley Pond, located at Monroe Road and Shade Valley Drive, as a storm water BMP in order to provide water quality benefits to the Briar Creek watershed. Since construction, excessive sediment deposition within the pond forebay has required excavation one to two times per year (see Photo 6, Appendix III). This excessive sedimentation alerted CSWS to the poor channel condition and bank erosion along the upstream channel within the project area. In order to improve the condition of the channel and alleviate this sediment source, CSWS hired Collins and Baker Engineers to design a channel stabilization / stream restoration plan in accordance with natural channel design principals. FIELD OBSERVATIONS On February 4, 2010 S&ME personnel visited the site and conducted a delineation to determine the location of jurisdictional streams and wetlands within the project area. The determination was conducted utilizing currently accepted methods as set forth in the 1987 Corps of Engineers Wetlands Delineation Manual. Stream assessments were conducted in accordance with DWQ and USACE guidelines. Results of the determination are depicted on Figures 3 and 4; representative photographs of the project area are included in Appendix III and their locations are noted on Figure 3. Field review identified one jurisdictional, relatively permanent water (Stream 1) that exhibits intermittent/seasonal flow within the project area. Stream 1 originates at the confluence of two non jurisdictional, ephemeral storm water drainages (see Photo 3, Appendix III). The northern storm water drainage originates at a riprapped outfall associated with a culvert under the Oakhurst Baptist Church parking lot and continues through an actively eroding gully spanned by a thick cover of privet (Ligustrum sinense) roots and Wisteria (Wisteria sinensis) vines (see Photo 2). The southern ephemeral channel emerges from a culvert under a walkway behind the church and continues down a riprap lined outfall to the origin of Stream l (see Photo 1). Additionally, the hillside between these drainages has experienced considerable mass wasting and erosion. Downstream of its origin, Stream I passes though a semi-open, canopied forested area dominated by privet and invasive vines. The channel is deeply incised to the extent that it has cut down to base material in many locations (Photo 4). Both banks are near- 2 Nationwide Permit No.27/Request for Jurisdictional Determination SWE Project No. 1357-10-006 Shade Valley Stream Enhancement, Charlotte, N.C. February 22, 2010 vertical, exposed, and actively eroding throughout most of the channel. In multiple locations, gullies in the bank have eroded into adjacent uplands and collapsed large pockets of riparian vegetation. Geomorphic structures within the channel are poorly defined and the standard riffle pool sequencing was not observed. The channel continues for 410 linear feet (If) before it flows into the culvert under parking lot of the Lake Hill Apartment Complex and into the forebay of Shade Valley Pond. For approximately 100 If prior to flowing into the culvert, the channel cuts though maintained lawn behind the apartment complex (Photo 5). Stream 1 has a drainage area of approximately 13 acres, most of which consists of commercial properties, residencies, roadway, and parking lots. An Approved Jurisdictional Determination form was prepared and incorporated with this PCN for verification, and is included in Appendix IV. Jurisdictional waters identified within the project area are depicted on Figure 3. A completed DWQ Stream Identification Form and USACE Stream Quality Assessment Worksheet are included in Appendix V. PROPOSED PROJECT IMPACTS The proposed channel enhancement design will result in 4101f of temporary stream impact to Stream 1. The restored channel is designed to be a geomorphically stable Rosgen B3 stream type (a moderately entrenched, cobble dominated stream). The downstream 3831f of the design involves grading of the banks to establish the proper cross sectional dimension, installation of five cross vane pool structures, and installation of constructed cobble riffles between the cross vanes. The "end-of-pipe" nature of the restoration reach implies introduction of no upstream bed material; for this reason, installation of coarse material (D50 = 4 inches) in riffles was deemed necessary to prevent transport of in-stream sediment causing the eventual degradation of the channel. Upstream of the cross vane / constructed riffle channel, a step-pool structure will be installed. This will impact 271f of the Stream 1 and the northernmost non jurisdictional storm drainage up to its culvert outfall origin. Additional riprap will be installed throughout the southernmost non jurisdictional stormwater drainage, and the culvert that serves as its origin will be replaced. Following bank grading and in stream structure installation, erosion control fabric will be installed over stream banks, benches, and terrace slopes, and a riparian seed mix will be applied. A plan view summary of the proposed temporary impacts is outlined in Figure 4. Full construction plan, profile, cross section, and planting details for the proposed project are included in Appendix II. PROTECTED SPECIES AND CULTURAL RESOURCES Protected Species S&ME's consideration of potential protected species habitat began with review of existing records obtained from federal and state sources. The U.S. Fish & Wildlife Service (USFWS) list of federally protected species (updated May 10, 2007) was consulted for a listing of protected species documented within Mecklenburg County, North Carolina. This review identified four protected species, three plants and one 3 Nationwide Permit No.27/Request for Jurisdictional Determination SWE Project No. 1357-10-006 Shade Valley Stream Enhancement, Charlotte, N.C. February 22, 2010 animal. Listed flora and fauna and their federal status are identified in Table 1. Explanations of rankings are included at the end of the table. Table 1: Federally Protected Flora and Fauna Summarv Species Federal Rank" County Status Habitat Present Echinacea laevigata Smooth coneflower E Current No Helianthus schweinitzii Schweinitz's sunflower E Current No Lasmigona decorata Carolina heelsplitter E Historical No Rhus michauxii Michaux's sumac E Historical No C - C11Ud11yr1Uu As part of the protected species review, S&ME also consulted the North Carolina Natural Heritage Program (NCNHP) Geographic Information Systems (GIS) database Virtual Workroom and Element Occurrence (EO) Database for a listing of endangered or threatened species EOs within or near the project area. This review found no EOs pertaining to federally or state protected species on record within a two-mile radius of the project area. S&ME completed a field reconnaissance of the project area on February 4, 2010. This effort revealed the project area consists primarily of wooded areas and adjacent maintained lawns. Wooded canopy is not the preferred habitat for the plant species of concern, and none of the three listed plant species were observed. Furthermore, the wooded areas within the project area were highly impacted by heavy growth of invasive vegetation. Based on the level of recent and continued disturbance, the project area was not considered to provide potential habitat for protected terrestrial species with a likelihood of occurring in Mecklenburg County. Though the Carolina heelsplitter is listed (historically) for Mecklenburg County, the proposed project involves impacts to Stream 1, an unnamed tributary to Edwards Branch, and will not impact streams that drain to known populations of Carolina heelsplitter or its designated critical habitat. No documented occurrences of Carolina heelsplitter are known for Edwards Branch or its tributaries. Accordingly, the proposed project is not anticipated to impact this species or its designated Critical Habitat. A copy of this PCN and attachments will be forwarded to the USFWS to provide an opportunity for comment on the proposed project. Cultural Resources S&ME reviewed the Mecklenburg County POLARIS GIS website layers pertaining to cultural resources. Layers reviewed included the Charlotte historic districts, historical properties, and historical cemeteries. One historical cemetery, Sharon Memorial Park Cemetery, was identified approximately 0.3 mile from the project site. This distance puts the cemetery well outside of the viewshed of the project, and would be considered well 4 Nationwide Permit No27/Request for Jurisdictional Determination SWE Project No. 1357-10-006 Shade Valley Stream Enhancement. Charlotte. N.C. February 22, 2010 outside of the area of potential impact given the highly urban land use between the project and the cemetery. A copy of this PCN and attachments will be forwarded to the State Historic Preservation Office (SHPO) to provide an opportunity for comment on the proposed project. AVOIDANCE AND MINIMIZATION In order to minimize impacts to jurisdictional waters, stabilization of the channel will be achieved through natural channel design principals rather than hard armoring of the banks. Bank armoring with riprap will be limited to non jurisdictional channels. Restoration plans for this channel have been specifically designed to minimize tree removal; all trees outside of the cut slopes are to be protected by the installing contractor. The project will not disturb the Federal Emergency Management Agency (FEMA) designated 100-year floodplain or result in impacts to the existing Surface Water Improvement and Management (SWIM) Buffer. REGULATORY CONSIDERATIONS Appropriate sediment and erosion control practices outlined in the most recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual" and approved by the local governing authority will be in compliance with specifications governing the proper design, installation, operation and maintenance of such Best Management Practices to comply with the appropriate turbidity water quality standard. Sediment and erosion control measures placed in waters will be removed and the original grade restored within two months after the Division of Land Resources has released the project. Impacts have been avoided and minimized, and appropriate measures will be taken during construction to allow flow and circulation patterns of waters of the U.S. to remain unaffected. Following construction, temporarily-disturbed upland areas will be restored to original grade and elevation. Excess material will be removed to a high ground disposal area. The proposed project will not result in additional impervious surface, and no permanent or temporary impacts to wetlands are anticipated. MITIGATION The proposed project has been designed according to natural channel design principals in order to improve the stability, stream habitat, and ecological condition of Stream I and the upstream non jurisdictional channels that feed it. The project will result in no loss of waters of the United States. Based on our experience with similar projects, we do not anticipate that compensatory mitigation for the proposed project is required. Although the project consists of stream enhancement, CSWS is not seeking mitigation credit for this project.

REVIEW PERFORMED FOR SITE EVALUATION (CHECK ALL THAT APPLY): [] Office (Desk) Determination. Date: Field Determination. Date(s): SECTION H: SUMMARY OF FINDINGS A. RHA SECTION 10 DETERMINATION OF JURISDICTION. There Are, no "navigable waters of the U.S." within Rivers and Harbors Act (RHA) jurisdiction (as defined by 33 CFR part 329) in the review area. [Required] Waters subject to the ebb and flow of the tide. Waters are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. Explain: B. CWA SECTION 404 DETERMINATION OF JURISDICTION. There Are "waters of the US." within Clean Water Act (CWA) jurisdiction (as defined by 33 CFR part 328) in the review area. [Required] 1. Waters of the U.S. a. Indicate presence of waters of U.S. in review area (check all that apply): ? TNWs, including terr itorial seas ?' Wetlands adjacent to TNWs Relatively permanent waters2 (RPWs) that flow directly or indirectly into TNWs ? Non-RPWs that flow directly or indirectly into TNWs ? Wetlands directly abutting RPWs that flow directly or indirectly into TNWs ? Wetlands adjacent to but not directly abutting RPWs that flow directly or indirectly into TNWs ? Wetlands adjacent to non-RPWs that flow directly or indirectly into TNWs ? Impoundments of jurisdictional waters ? Isolated (interstate or intrastate) waters, including isolated wetlands b. Identify (estimate) size of waters of the U.S. in the review area: Non-wetland waters: -410 linear feet: 2 to 4 width (ft) and/or acres. Wetlands: acres. c. Limits (boundaries) of jurisdiction based on: Established by OHWM. Elevation of established OHWM (if known): 2. Non-regulated waters/wetlands (check if applicable):3 Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below. s For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section III.F. SECTION ID: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section HI.A.1 and Section IH.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2 and Section HI.D.L; otherwise, see Section HI.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 HI.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 M.B.1 for the tributary, Section HI.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 IH.C below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 13 acres Drainage area: 45 acres Average annual rainfall: 43 inches Average annual snowfall: 6 inches (ii) Physical Characteristics: (a) Relationship with TNW: ? Tributary flows directly into TNW. ® Tributary flows through 3 tributaries before entering TNW. Project waters are 25-30 river miles from TNW. Project waters are 1 (or less) river miles from RPW. Project waters are 15-20 aerial (straight) miles from TNW. Project waters are 1.(or less) aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. Identify flow route to TNW5: SEASONAL CHANNEL BECOMES RPW AND FLOWS INTO EDWARDS BRANCH, WHICH FLOWS INTO BRIAN CREEK, THEN LITTLE SUGAR CREEK, SUGAR CREEK, AND THEN INTO THE CATAWBA RIVER (TNW). Tributary stream order, if known: FIRST. (b) General Tributary Characteristics (check all that apply): Tributary is: ® Natural ? Artificial (man-made). Explain: ? Manipulated (man-altered). Explain: Tributary properties with respect to top of bank (estimate): Average width: 2 TO 4 feet Average depth: 4 TO 8 feet Average side slopes: Vertical (1:1 or less). Primary tributary substrate composition (check all that apply): ® Silts ? Sands ? Concrete ? Cobbles ® Gravel ? Muck ? Bedrock ? Vegetation. Type/% cover: ? Other. Explain: Tributary condition/stability [e.g., highly eroding, sloughing banks]. Explain: VERY HIGHLY ERODING. Presence of run/riffle/pool complexes. Explain: LIMITED- QUICKLY INCISING, LEADING TO POORLY DEFINED COMPLEXES.. Tributary geometry: Relatively straight Tributary gradient (approximate average slope): 3 % (c) Flow: Tributary provides for: Seasonal flow Estimate average number of flow events in review area/year: 20 (or greater) Describe flow regime: LIKELY FLOWS DURING WET SEASON AND FOLLOWING RAIN EVENTS. Other information on duration and volume: Surface flow is: Confined. Characteristics: Subsurface flow: Unknown. Explain findings: ? Dye (or other) test performed: Tributary has (check all that apply): ® Bed and banks ® OHWM6 (check all indicators that apply): ? clear, natural line impressed on the bank ? ? changes in the character of soil ? shelving ? ? vegetation matted down, bent, or absent ? ® leaf litter disturbed or washed away ® sediment deposition ? water staining ? ? other (list): the presence of litter and debris destruction of terrestrial vegetation the presence of wrack line sediment sorting scour multiple observed or predicted flow events abrupt change in plant community ? Discontinuous OHWM.7 Explain: If factors other than the OHWM were used to determ High Tide Line indicated by: ? oil or scum line along shore objects ? fine shell or debris deposits (foreshore) ? physical markings/characteristics ? tidal gauges ? other (list): ine lateral extent of CWA jurisdiction (check all that apply) Mean High Water Mark indicated by: ? survey to available datum; ? physical markings; ? vegetation lines/changes in vegetation types. (iii) Chemical Characteristics: 5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. 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 OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. 'Ibid. Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: WATER QUALITY IS LIKELY POOR - STREAM DRAINS A HIGH DENSITY URBAN AREA WITH MULTIPLE PARKING LOTS AND A LARGE ROADWAY (MONROE ROAD). EXPOSED SEWER PIPE WAS ALSO OBSERVED IN THE STREAM. Identify specific pollutants, if known: (iv) Biological Characteristics. Channel supports (check all that apply): ® Riparian corridor. Characteristics (type, average width): -30 FEET OF FORESTED AREA, DOMINATED BY INVASIVE SPECIES. ? Wetland fringe. Characteristics: ? Habitat for: ? Federally Listed species. Explain findings: ? Fish/spawn areas. Explain findings: ? Other environmentally-sensitive species. Explain findings: ? Aquatic/wildlife diversity. Explain findings: 2. Characteristics of wetlands adjacent to non-TNW that flow directly or indirectly into TNW (i) Physical Characteristics: (a) General Wetland Characteristics: Properties: Wetland size: acres Wetland type. Explain: Wetland quality. Explain: Project wetlands cross or serve as state boundaries. Explain: (b) General Flow Relationship with Non-TNW: Flow is: Pick List.

SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to carry pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: 2.

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 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 the 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. Total Score (from reverse): 28 Comments: No macrobenthos were observed. Channel is rapidly eroding and incising. Evaluators Signature: L Date: 2/4/210 This channel evaluation form is intended to be used only as a guide to assist landowners and environmental professionals In gathering the data required by the United States Corps of Engineers to make a preliminary assessment of stream quality.
