Coral, JR. SP.CRE"fARY Q~~~oe~~ AUG 1 0 Zp~~ DENR-WAlER0DAl1TY ~1 Wms AND s10RM1'fAiHt BRANp1 Subject: Nationwide 14 Permit Application SR 1533, Everett Road, Streambank Stabilization Transylvania County State Project No. 140.088023 (DWQ Minor Permit Fee $240) Deaz Ms. Beckwith: The North Carolina Department of Transportation (NCDOT) proposes to realign and stabilize a roadside stream, an unnamed tributary to the French Broad River, and repair the shoulder on Everett Road, SR 1533. Recent heary rains have caused a shoulder failure and the pavement is in jeopardy of being undercut. The site is approximately 3925 feet east of SR 1504, Old Hendersonville Highway. Everett Road is a secondary paved road that conveys local traffic. The existing channel is pazallel to the road and a maintained yard and receives significant stormwater from a relatively steep driveway immediately upstream of the project. To repair the eroding shoulders, the channel will be realigned along sections of the channel that are cutting into the shoulder and rock cross vanes will be installed to maintain the channel stability. Gabions or large shot rock will be used. to reconstruct the shoulder. An effort will be made to maintain existing stable portions of the channel as much as possible rather than excavating the entire 150 feet. I am enclosing a PCN, photographs showing a typical cross section of the proposed channel, an aerial photo showing approximate vane locations, a marked county map, a USGS map and photographs. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. There aze no records of threatened or endangered species for the French Broad River in the immediate vicinity of the shoulder stabilization project. The unnamed. tributary is approximately one foot wide at Everett Road and does not have sufficient flow to Division 14, District 1 Phone: (828) 891-7911 4142 Haywood Road, Mills Aiver , NC 28759 Faz: (828) 891-5026 „~. SR 1533 Everett Road support mussels and fish habitat is limited. The riparian zone consists of maintained grassed azeas including eroding bank and road shoulders; therefore, the quality of aquatic and terrestrial habitat is of poor quality. Water will be diverted-away from the work area to prevent-the movement of sediments to downstream areas. Adverse environmental effects from 150 feet of streambank stabilization should be minimal. The project footprint will be limited. to areas (i.e., shoulder areas and stream channel) that have been disturbed previously. Therefore, we believe there is little potential to affect azchaeological or historical resources. The best management practices-will be used-to minimize and.control sedimentation and erosion on this project. Sandbags will be used to divert water away from the work area to minimize erosion and sedimentation from the bank stabilization. The construction foreman will review all sedimentation control measures during gabion or rock installation to ensure sedimentation is controlled effectively. The sedimentation control devices will be in place prior to construction. Impacts to Waters of the United States The unnamed stream is a tributary of the French Broad River and is not shown as a perennial stream on the USGS topographic map. The stream is approximately one foot in width with a well-defined channel composed primarily of sand and gravel. The channel lacks vegetation. The unnamed tributary parallels Everett Road for approximately 150 feet before reaching a culvert. The culvert then takes the stream under the road and approximately 207 feet to an agricultural channel. The agricultural. channel then flows approximately 2100 feet to the French Broad River. The French Broad River meets the definition of a Traditional Navigable Water. For these reasons, we believe that the unnamed tributary is a Relatively Permanent Water under the jurisdiction of the U. S. Army Corps of Engineers. In order to repair the shoulder, it will be necessary to impact waters of the United States in the French Broad. River Basin. Listed below is a summary of the impacts.

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 Rnpanar have been met The agencies will assertjurisdiction over non-navigable tributaries of TNWs where the tributaries are '4elafively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous Bow at least seasonally (e.g., typically 3 months). A wetland that directly abuts en RPW is also jurisdietlooel. If the aquatic resource is not a TN~i', but has year-round (perennial Bow, skip to Section IILD.2. If [he aquatic resource is a wetland directly abutting a tributary with perennial Bow, strip to Section III.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Carps districts and EPA regions wBl 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 i(any) and a traditional navigable water, even though a significant nexus finding is not required ns o matter of law. If the waterbody is not an RPW, or a wetland dtrecty abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with n 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 caves a tributary with adjacent wetlands, complete Section III.B.1 for the tributary, Secton IILB.2 for any onsite wetlands, end Secflon IILB3 for all wetlands adjacent to that tributary, both onsite and affsite. The determination whether u significant nexus erists is determined in Section ID.C below. 1.

SIGNIFICANT NEXUS DETERMINATTON A significant nexus analysis will assess the flaw characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if [hey significantly affect the chemical, physical, and biological integrity of a TNW. Fdr each of the following situations, n significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more then 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 [be 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 eftectsoo the TNW, asidentitied in the RapanasC„uidauce and discussed in the Instructional Guidebook. Factors to consider include, for example: • Dces 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? •. Dces 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 Mbutary, in.combination.with-its adjacent wetlands (if any), have the capacity to transfer nutrients and organic cacbon.that support doumstream foodwebs7 • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW?

The base channel width is 2 feet with banks on a 2:1 slope with an approximately 4-foot shoulder. The streambanl<s are adjacent to a private yard and will be maintained in grass. Only the sections that need shifting away from road will be excavated and then tied back to the existing channel.
