Shrub layer is dominated with Pokeberry (Phvtolacca americana), and Chinese Privet (Ligustrum sinense) indicating that the area evaluated was historically wetter than the more recent growing seasons based on comparison of the tolerance of tree species and shrubs.

The data point location is approximately 75 feet from an intermittent stream which was entirely dry. There is evidence of flood flows in this area based on the drainage patterns, micro-topography, and wrack lines. Rainfall of 0.22 inches occurred within 36-48 hours prior to the evaluation, and rainfall of 0.69 inches occurred within the prior week (Charlotte Douglas Airport).

The profile location was in a depression area approximately 3 inches lower than the average ground surface. WETLAND DETERMINATION Hydrophytic Vegetation Present? Yes X No Is the Sampling Point Wetland Hydrology Present? Yes X No Within a Wetland? Yes_ No X Hydric Soils Present? Yes No X Remarks: The site does not meet wetland criteria based on lacking hydric soil indicators. Although the soil series is listed as hydric, the observed profile indicated that the upper surface is a higher chroma soil (4) and evidence of reduction (high water table) did not occur until 20 inches from the soil surface, which was in a low spot in the general area. Although not a problem site, there have been changes in the adjacent land use and watershed that could affect the hydrology of this location. Upslope there is an on-line impoundment to the intermittent stream. Down slope there is a channelized portion of the intermittent stream where is crosses the golf course. Parallel to the forested area and along the toe-of-slope of the floodplain there is a sanitary sewer utility easement. Therefore, the floodplain does not receive significant flood flow (impoundment), has overland flow diverted (utility easement), and conveys flow rapidly (incised channel down slope). So although there is evidence that hydrology indicators are present (wrack lines and drainage patterns), it is unlikely that this location receives and detains sufficient hydrology to support a wetland community.

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.

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 he not jurisdictional. Explain: Where the intermittent stream flows into the floodplain for the larger perennial stream north of the site (off- site) the valley slope shanges and the stream disappears. This area has also historically been used as a grass swale maintained as part of the golf course fairway. The feature does not exhibit wetland indicators, primarilly vegetation, ' 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 TN W 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. nor a OHWM characteristic of a tributary. Instead, the feature is a maintained grass swale that provides hydrologic connection to the upslope and downslope stream segments. SECTION 111: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section III.A.1 and Section III.D.1. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections II1.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: Summarize rationale supporting determination: 2. Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section III.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbodya is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Section III.B.2 for any onsite wetlands, and Section III.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section III.C below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: -80 acres Pick List Drainage area: -80 acres Pick List Average annual rainfall: inches Average annual snowfall: inches (ii) Physical Characteristics: (a) Relationshipwith'I'NW: ? Tributary flows directly into TNW. ® Tributary flows through 4 tributaries before entering'I'NW. Project waters are 10-15 river miles from TNW. Project waters are Pick List river miles from RPW. Project waters are 10-15 aerial (straight) miles from TNW. Project waters are 10-45 aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Confluence with T'NW is in South Carolina. Identify flow route to T N W5: 'T'ributary flows to UT to McAlpine Ck, then to Sugar Creek (in SC), then flows into Catawba River. ' Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the arid West. 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. Tributary stream order, if known: first. (b) General Tributary Characteristics (check all that apply)- Tributary is: ® Natural ? Artificial (man-made). Explain: ® Manipulated (man-altered).

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 Rnpanos 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.

Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The CBP-7 Site is a 15.72 acre sub-parcel within the larger 166.7 acre property which also includes the Ballantyne Golf Course (see attached figures). The CBP-7 Site is undeveloped with areas of cleared forest, forest, and a portion of the golf course. Land use around the site is predominately commercial development, golf course, and Interstate 485. South and west of the site is predominately residential development along Ballantyne Commons Road. The northeast portion of the 15.72-acre site includes an intermittent stream that flows north towards McApline Creek. In the eastern portion of the 15.72-acre site, the stream is forested. Downstream from the forested segment, the stream has been cleared for the golf course. Further downstream, the stream disappears as the valley slope changes where the small tributary confluences with a larger perennial stream (LIT to McAlpine Creek) and its floodplain which is off-site, just north of the 15.5-acre site. This drainageway area where the stream disappears also crosses the golf course. The drainage feature in this area is a non-jurisdictional vegetated swale that provides a hydrologic connection to the upslope and downslope stream segments. There are no wetlands within the 15.72-acre site. 3b. List the total estimated acreage of all existing wetlands on the property: None within the 15.72-acre site 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 645 linear feet within the 15.72-acre site (see that attached figures) 3d. Explain the purpose of the proposed project: The proposed development will provide commerical office space to meet demand for the Ballantyne area in South Charlotte. The proposed fill/excavation is necessary to allow development of the site. The stream has been avoided to the maximum extent practicable, and unavoidable impacts have been minimized. 3e. Describe the overall project in detail, including the type of equipment to be used: The proposed development includes three corporate buildings, two parking decks and minimal surface parking in front of the buildings along the road (see the attached figures). The development will include stormwater management using wet ponds. Page 3 of 11 PCN Form - Version 1.3 December 10, 2008 Version 4. Jurisdictional Determinations 4a.

Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed development maximizes use of the project area for the construction of three buildings. To minimize site disturbance and imperviousness, while accomodating the structures and providing parking, two parking decks will be constructed. Surface parking at the entrances of the buildings will be included as well. Topographically, the site slopes from Ballantyne Corporate Place road to the northwest towards the stream. A sanitary sewer easement is located parallel to the stream along the toe-of-slope of the hill. The proposed impact to the intermittent stream includes relocation of the stream so that the stormwater pond will be constructed off-line. The location and configuration of the pond was chosen to minimize the length of stream to be relocated. The second pond avoids impact to jurisdictional areas all together by locating in an area where the stream transitions to a non-jurisdictional vegetated swale. By installing a pipe through that pond, the hydrologic connection between jurisdictional areas will be maintained, but the stormwater pond will remain off-line. Refer to the attached figures for more detail. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The stream relocation will be constructed and stabilized prior to the construction of the pond so that construction activites for the pond will be separate from the stream channel. 2.

If this project DOES require a Stormwater Management Plan, then provide a brief, na rrative description of the plan: Stormwater management measures shall be designed in accordance with the City of Charlotte Post Construction Controls Ordinance (PCCO) for water quantity and quality purposes. In accordance with the PCCO stormwater quantity requirements, the 2-year and 10-year peak storm discharge rates and the 1-year 24-hour runoff volume are not to exceed the predevelopment conditions. Additionally, runoff from the project area is required t o be treated to remove at least 85% of the Total Suspended Solids (TSS) in the runoff. The site is designed with a series of two Wet Detention Ponds to handle both the quantity and quality requirements. The project area is exempt from the City of Charlotte S.W.I.M. buffers due to its approved rezoning in 1993 by the City of Charlotte. At this time, the Stormwater Management Plan has not been submitted to the City of Charlotte, since further site design is required. However, the proposed stormwater management is anticipated to be sufficient to meet the City's requirements for the site . ® Certified Local Government 2e.
