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: t i The streambanks of Hodges Creek are actively eroding throughout the Linzey Enterprises, LLC. property. Currently the property is used for a veterinary clinic (Animal Emergency & Pet Care Clinic of the High Country). Hodges Creek flows through the property from West to East. The river left section is beginning to undermine a dog walking path that the vet has installed. 3b. List the total estimated acreage of all existing wetlands on the property: 0 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: Approximately 240 linear feet of Hodges Creek 3d. Explain the purpose of the proposed project: The purpose of this project is to enhance Hodges Creek to decrease streambank erosion and reduce sediment export from the site. Project elements include: streambank stabilization techniques including rock vanes (single, cross), vegetated boulder toe, bank sloping, and riparian planting. Riparian planting, bank sloping, and boulder toe protection will help stabilize erosive banks. Rock vanes (single, cross) will be used to redirect the thalweg from the banks and provide grade control through the reach. A large gravel bar (river right), which has developed due to upstream erosion (river left) will be reworked to support proposed structures. 3e. Describe the overall project in detail, including the type of equipment to be used: The proposed streambank stabilization will occur along approximately 240 linear feet of Hodges Creek (see Site Plan). Rock vanes and vegetated boulder toes are proposed to be installed along the creek in the eroded areas. Following construction, the disturbed areas will be seeded, matted (coconut fiber), and planted with native trees, shrubs, and herbaceous species in all direct riparian areas (see re- vegetation detail). Proposed excavation equipment includes: hydraulic thumb trac- hoe(s), and tandem axle road dump truck(s). All heavy equipment will be kept out of the stream channel during project construction except where absolutely necessary to install boulder structures.

Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The proposed work and associated impacts are intended to stabilize Hodges Creek and the streambanks along the property reach while minimizing impacts to aquatic resources. Design measures which minimize impacts include vegetated boulder toe protection intended to decrease site sedimentation. All streambanks will then be planted with appropriate native species (see re -veg detail). All disturbed buffer areas will be immediately seeded upon completion (temporary - annual ryegrass), matted (coconut/coir matting), and stabilized at the close of each construction day. Following construction, the banks of the restored channel will be seeded with a native floodplain mix (permanent seed). Live stakes and matting staples will be used to secure the coconut matting in these high- stress areas. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. All heavy equipment will be kept out of the stream channel during project construction except where absolutely necessary to install vegetated boulder toe protection. Any entering of the channel or immediate riparian area will be done with new equipment, no hydraulic leaks tolerated. Disturbance of channel bottom and banks and equipment access areas shall be held to the minimum necessary to allow for bank stablization sufficient to restore the hydraulic capacity of the stream channel. Streamflow will be diverted around the work area when channel base flow is less than 5 cfs. Flow diversion will not be performed for work that is done from the top of bank, or minor placement of structures. 2.

[Required] 1. Waters of the U.S. a. Indicate presence of waters of U.S. in review area (check all that apply): t ❑ TNWs, including territorial 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: -240 linear feet: -15 (bkf) width (ft) and/or acres. Wetlands: 0 acres. c. Limits (boundaries) of jurisdiction based on: Established by OHWM -! Elevation of established OHWM (if known): - 3150- 3250feet. 2. Non - regulated waters/wedands (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. 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). ' Supporting documentation is presented in Section HIT. 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 III.A.1 and 2 and Section III.D.1.; otherwise, see Section III.B below. 1. TNW Identify TNW: No TNW found onsite. Summarize rationale supporting determination: 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 Rapawos 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.DA. 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 IILB.3 for all wetlands adjacent to that tributary, both onsite and oftsite. The determination whether a significant nexus exists is determined in Section III.0 below. 1. Characteristics of non -TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: 1.1 sq mdtraree' es' es Drainage area: 1.1 square miles Average annual rainfall: approx 55 inches Average annual snowfall: aprrox 30+ inches (ii) Physical Characteristics: (a) Relationship with TNW: ❑ Tributary flows directly into TNW. ® Tributary flows through i tributaries before entering TNW.

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. Significant nexus findings for non -RPW and its adjacent wetlands, where the non -RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: 3. Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW.
