Elliott, Johnson and Tompkins, Enclosed is a Pre - Construction Notification (PCN) for a Nationwide Permit #27 requesting authorization for the stream channel relocation and stabilization project on Lots 93 & 94 in Bromley Estates, in Weddington, Union County, North Carolina. Approximately 120 linear feet of a severely eroding meander bend will be eliminated by creating a newly relocated channel in the existing floodplain. Through prior coordination with USACE, NCDWR, and USFWS, the proposed channel relocation was indicated as a more favorable approach than the previous plan of stabilizing the eroding bend with gabion baskets. Also, through this coordination, we were verbally authorized to proceed with the stabilization part of the project (i.e. site preparation, temporary diversion, and filling/grading eroding bank) while the final permit application was being prepared due to the severity of the erosion and the potential threat to the existing residence. Toll NC II, LP who is developing Bromley Estates currently owns Lot 93 and is working in conjunction with the existing landowner on Lot 94 to stabilize the bank therefore Toll NC II, LP is listed in PCN as the applicant and owner. Thank you for your consideration and please contact me if you have any questions, (828) 708- 7059 or email at amanda.iones Lwetlands -epg com.

The primary goal isto redirect,the flow through a point bar to reduce the pressure on the slope and then to stabilize the slope that provides structural support. The secondary goal is the restoration of vegetation for long term stabilization and ecological enhancement. The stream channel will be diverted to eliminate a severely eroding meander bend. Approximately 40 linear feet of new channel will be constructed through the flbodplain as depicted on attached drawings. This new channel will be constructed utilizing natural channel design techniques to account for slope changes and grade control. Appropriately sized log steps will be installed and buried to depth needed to stabilize the, longitudinal profile of channel. The number and placement of these structures will be based on adjustments made in the field during construction. A total of approximately 40 linear feet upstream and downstream of the diversion will also be enhanced with structures when necessary to aid in the transition from the newly created channel. Log vanes are proposed to aid in thi's transition. The cross - section of the channel will be constructed with an appropriate bankfull width and floodplain bench to mimic the existing channel conditions upstream and downstream. The relocation project area has two general planting zones which are depicted by the different vegetation used in stabilization labeled Lower slope and Upper slope. The Lower slope is from the toe of the slope to 15' upslope will be stabilized with native seed, coir fiber matting, and live stakes. Coir fiber logs will be placed at the,waters.edge running the length of the project area. The area which will be live staked is approximately four rows from slope side of the coir fiber logs. The Upper slope (15' — 30') is to receive native seed, coir fiber matting (900 or coir fiber blankets w /out plastic can be used) and tublings with sleeves /treebands. During construction a diversion ditch /pipe will be installed to allow the stream to continue to naturally flow. A temporary barrier should be placed just below the diversion pipe to ensure flow is directed through the diversion pipe. Rip-rap should not be placed into the stream at any time only native /natural stone can be used. Erosion control methods should be implemented prior to earth moving to prevent sedimentation migration,into the stream (silt fencing.as well as stabilization fabrics). Temporary check dams should be implemented downstream of the construction area prior to work. Recommended locations of cheek dams will be located in the field. Native seed mixes (no fescue), live stakes, and tublings are listed below in the Species List. The normal planting time for live stakes is during the dormant season October -March and tublings can be planted at most tirimes,of the year. All vegetative planting should have a minimum of 75% survival rate in the first year and - anything less than that should be reinstalled. If fertilizers are applied during installation it is recommended that only organic (and /or organic fertilizer with mycorrhizae) fertilizer be used. The entire enhancement area is to be matted with coir fiber erosion fabric. The relocated /enhancement reach once constructed will be visually inspected until April 2015 on a minimum bi- weekly basis or immediately following a rain event. Depending upon observations, maintenance and /or repair recommendations will be made. The monitoring period may be altered to reduce visual inspections based on,the stability of the channel and survival success of planted vegetation.

A wetland that directly abuts an RPW is'also jurisdictional. If thesaquatic 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 wdlanclude 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 waterbodyi 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 IH.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.

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 nf 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, iwcoiribination 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 itsadjacent wetlands (if any), have the capacity to carry pollutants or, flood waters to TNWs, onto reduce'the amount of'pollutants,or flood waters reachmg:a TNW9 • 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 TNW9 • Does the,tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs9 • Does the tributary, m.combmation with its adjacent wetlands (if any), have,other relationships to the physical,, chemical, or biological integrity of the TNW9 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.
