CHARLOTTE, NC 28273 866-527-1177 (office) 704-527-1133 (fax) Subject: Pre-Construction Notification Pursuant to Nationwide Permit Nos. 27 and 33 and Water Quality Certification Nos. 3689 and 3688 10137 Thomas Payne Circle Maintenance Project Charlotte, North Carolina Carolina Wetland Services Project No. 2008-2354 The 10137 Thomas Payne Circle Maintenance Project is located approximately 1.5 miles southwest of the Matthews Pineville Road - Providence Road intersection in Charlotte, North Carolina (Figure 1, enclosed). The purpose of this project is to alleviate erosion and enhance aquatic habitat within an existing stream channel. Charlotte Storm Water Services (CSWS) has contracted Carolina Wetland Services, Inc. (CWS) to provide Section 404/401 permitting services for this project. Applicant Name: Charlotte Storm. Water Services, Isaac J. Hinson Mailing Address: 600 East Fourth Street, Charlotte, NC 28202 Phone Number of Owner/Applicant: 704-336-4495 Street Address of Project: 10137 Thomas Payne Circle, Charlotte, NC Waterway: UT to Fourmile Creek Basin: Catawba (HU# 03050103) City: Charlotte County: Mecklenburg Decimal Degree Coordinate Location of Project Site: N35.07738°, W80.79738° USGS Quadrangle Name: Weddington, NC 1988 Current Land Use The current land use for the project area is residential with maintained lawns and small adjacent wooded areas. Dominant vegetation within the project area consists of sweetgum (Liquidambar styraciua), glossy privet (Ligustrum lucidum), and Johnson grass (Sorghum halepense). According to the Soil Survey of Mecklenburg County', on-site soils consist of Wilkes loam (WkD) and Monacan loam (MO). Wilkes soils are well-drained, while Monacan soils are somewhat poorly-drained. Monacan soils are listed by the NRCS as soils with hydric inclusions for Mecklenburg County2. Jurisdictional Determination On July 15, 2008, CWS's Paul Bright and Jamie MacMartin investigated on-site jurisdictional waters of the U.S. using the U.S. Army Corps of Engineers (USACE) - Routine On-Site Determination Method. 1 United States Department of Agriculture, 1971. Soil Survey of Mecklenburg County, North Carolina. z NRCS Hydric Soils of North Carolina, December 15, 1995. NORTH CAROLINA* SOUTH CAROLINA • NEW YORK WWW.CWS-INC.NET July 29, 2008 Ms. Amanda Jones Page 2 of 3 This method is defined in the 1987 Corps of Engineers Wetlands Delineation Manual.3 There are no jurisdictional wetland areas within the project limits. A Routine On-Site Data Form representative of non jurisdictional upland areas has been enclosed as data point 1 (DPI). Jurisdictional waters of the U.S. were classified according to recent North Carolina Division of Water Quality (NCDWQ)4 and USACE guidance. A NCDWQ Stream Classification Form, USACE Stream Quality Assessment Worksheet, and USACE Approved Jurisdictional Determination Form for Stream A are enclosed (SCP1). The results of the on-site field investigation indicate that there is one jurisdictional stream channel (Stream A) located within the project area (Figure 1, enclosed). Stream A is an unnamed tributary to Fourmile Creek. Fourmile Creek is within the Catawba River basin (H-U# 03050103)5 and is classified as "Class C" waters by the NCDWQ. Stream A flows northwest through the project area for approximately 192 linear feet (Figure 1, enclosed). Stream A exhibited a strong bed and bank, substrate consisting of silt to large cobbles, and an average ordinary high water width of 3-5 feet. Due to the evidence of typical year-round flow, Stream A was classified as a relatively permanent water (RPW) according to USACE/EPA guidance (AJDF, Perennial RPW Stream A). Perennial RPW Stream A scored 41 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 30 out of a possible 71 points on the NCDWQ Stream Classification Form, indicating perennial status (SCP1, enclosed). Photographs of Perennial RPW Stream A are enclosed as Photographs A - D. Agency Correspondence Cultural Resources A letter was forwarded to the State Historic Preservation Office (SHPO) on July 15, 2008 to determine the presence of any areas of architectural, historic, or archaeological significance that would be affected by the project. As of the date of this submittal, a response from SHPO has not yet been received. The project is located in a residential subdivision; the occurrence of any area of architectural, historic, or archaeological significance is unlikely. Protected Species A letter was forwarded to the North Carolina Natural Heritage Program (NCNHP) on July 15, 2008 to determine the presence of any federally-listed, candidate endangered, threatened species or critical habitat located within the project area. In a response letter, dated July 21, 2008 (enclosed), the NCNHP stated that there are two records of Carolina Birdfoot-trefoil (Lotus helleri) located within two miles of the project area. This Federal Species of Concern and NC-significantly Rare Plant is known from two locations north and south of Providence Road within 0.1 mile of Providence Road. The Carolina Birdfoot-trefoil is found mainly in open woods over clay soils and along roadsides. The project is located in a residential subdivision and within an area of maintained lawn; there is no potential habitat for this species within the project area. Purpose and Need for the Project The existing stream at 10137 Thomas Payne Circle is experiencing erosion issues. Portions of the existing channel banks are eroding and undercutting towards the house. To control erosion, CSWS is proposing to fill and relocate a portion of an existing stream channel. Impacts to on-site jurisdictional waters are necessary to alleviate channel erosion and enhance aquatic habitat. 3 Environmental Laboratory.

Hydrologic Unit Map, State of North Carolina. 2 July 29, 2008 Ms. Amanda Jones Page 3 of 3 Avoidance and Minimization Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable. The restoration work will be stopped at the shortest point as dictated by the channel's profile and stability. Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. The newly relocated channel will be constructed in the dry in accordance with Water Qualification No. 3689. Proposed Impacts to Jurisdictional Waters Unavoidable temporary impacts to Perennial RPW Stream A total approximately 166 linear feet and are the result of filling the old channel and creating a new restored channel. The existing channel is currently experiencing severe erosion. To alleviate erosion and enhance aquatic habitat, approximately 166 linear feet of channel will be filled and relocated directly northeast of the existing stream channel. The new channel will be approximately 167 linear feet in length. A proposed plan view drawing has been included (Figure 2, enclosed). Proposed work includes establishing adjacent floodplain benches, constructing banks to 3:1 slopes, and creating gentle meanders. In addition, five constructed riffles will be installed to enhance instream habitat. To enhance the adjacent riparian buffer several trees and shrubs will replace mowed grass adjacent to the stream. A typical cross section drawing has been included showing proposed bank slopes and benches (Figure 3, enclosed). On behalf of CSWS, CWS is submitting a Pre-Construction Notification Application with attachments in accordance with Nationwide Permit General Condition No. 27 and pursuant to Nationwide Permit (NWT) Nos. 27 and 33, (enclosed). Compensatory Mitigation Construction of this project will result in a net increase in aquatic resource functions and values, and create one linear foot of perennial stream channel; therefore, no mitigation is currently being proposed for this site.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Impacts to on-site jurisdictional waters of the U.S. have been reduced to the maximum extent practicable The restoration work will be stopped at the shortest point as dictated by the channel's profile and stability. Proper sediment and erosion control measures will be used to minimize disturbances to downstream waters. The newly relocated channel will be constructed in the dry in accordance with Water Qualification No. 3689. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, hut are .not-limited to: reducing the size of the project; establishing and .maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation - easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. Page 5 of 8 Construction of this project will result in a net increase in aquatic resource functions and values, and create one linear foot of perennial stream channel; therefore no mitigation is currently being proposed for this site. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

Explain: ' Boxes checked below shall be supported by completing the appropriate sections in Section III below- 2 For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). 3 Supporting documentation is presented in Section II1.F. SECTION III: 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 HI.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. CIIARACTERISTICS 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 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.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.

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 OHWlvi has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break.

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

Tributaries of TNWs where tributaries typically flow year-round are jurisdictional. Provide data and rationale indicating that tributary is perennial: Stream A flows northwest through the project area for approximately 192 linear feet (Figure 1, enclosed). Stream A exhibited a strong bed and bank, substrate consisting of silt to small cobbles, and an average ordinary high water width of 3-5 feet. Due to the evidence of typical year-round flow, Stream A was classified as a relatively permanent water (RPW) according to USACE/EPA guidance (AJDF, Perennial RPW Stream A). Perennial RPW Stream A scored 41 out of a possible 100 points on the USACE Stream Quality Assessment Worksheet and 30 out of a possible 71 points on the NCDWQ Stream Classification Form, indicating perennial status (SCP1, enclosed). Photographs of Perennial RPW Stream A are enclosed as Photographs A - D.

Easley, Govemor July 21, 2008 Jamie MacMartin and Paul Bright Carolina Wetland Services 550 E. Westinghouse BLVD Charlotte, NC 28273 SUBJECT: Request for records search 10137 Thomas Payne Circle Maintenance Project Charlotte, NC, Carolina Wetland Services Project No. 2008-2354 Dear Ms. MacMartin and Mr. Bright: William G. Ross Jr., Secretary The Natural Heritage Program has two records of a rare species within two miles of the project area. Carolina Birdfoot- trefoil (Lotus helleri), a Federal Species of Concern and NC-significantly Rare plant, is known from two locations north and south of Providence Road within 0.1 mile of Providence Road. This species is adapted for early successional habitat and is an early colonizer of open, disturbed ground. Although our maps do not show records of natural heritage elements within the project area, it does not necessarily mean that they are not present. It may simply mean that the area has not been surveyed. The use of Natural Heritage Program data should riot be substituted for actual field surveys, particularly if the project area contains suitable habitat for rare species, significant natural communities, or priority natural areas. You may wish to check the Natural Heritage Program database website at www.ncnhp.org for a listing of rare plants and animals and significant natural communities in the county and on the quad map. Our Program also has a website that allows users to obtain information on element occurrences and significant natural heritage areas within two miles of a given location: http://nhpweb.enr.state.ne.us/nhis/public/gmap75_main.phtml. The user name is "public" and the password is "heritage". You may want to click "Help" to download the user's manual before you use the application. This website gives you instant answers to information requests about specific locations, without having to wait for NHP staff to respond. NC OneMap now provides digital Natural Heritage data online for free. This service provides site specific information on GIS layers with Natural Heritage Program rare species occurrences and Significant Natural Heritage Areas. The NC OneMap website provides Element Occurrence (EO) ID numbers (instead of species name), and the data user is then encouraged to contact the Natural Heritage Program for detailed information. This service allows the user to quickly and efficiently get site specific NHP data without visiting the NHP workroom or waiting for the Information Request to be answered by NHP staff.
