SAW-2020-00632 NC DWR Project No. 2020-1654 Madison County, North Carolina Dear Ms. Homewood and Ms. Boggs: The NC Division of Water Resources (DWR) issued a permit denial letter dated July 28, 2021. By means of this letter, the applicant, Mulberry Farm —Madison LLC represented by Richard Kelly is reapplying for the 401 Individual Permit application for review of impacts related to redevelopment activities and to update and clarify project information that has changed since prior submittals. The project site consists of +/- 450.53 acres located at 1126 Upper Thomas Branch Road, Marshall, North Carolina. The applicant is seeking a Section 404 Individual Permit and 401 Individual Water Quality General Certification for 1,869 linear feet (0.143 acres) of impact to streams and 0.015 acres of impacts to wetlands on Thomas Branch and unnamed tributaries to Thomas Branch, and for 193 linear feet (0.018 acres) of impact to streams and 0.007 acres of impacts to wetlands on Hopewell Branch. The impacts are associated with the construction of a residential education and training center called the School of Wholeness and Enlightenment (SOWE). The Applicant has conducted further review of the development with its various consultants to determine what, if any, further modifications might be undertaken to enlarge the avoidance envelope or further minimize impacts to wetland and/or stream resources. Based on that review and the applicants desire to be as responsive as possible to the regulatory concerns for permitting this project, the Applicant proposes the following adjustments: BDAs 1 and 6 have been eliminated. This reduces stream impact by 442 If (0.032 ac) and wetland impact by 0.035 ac. BDAs 1 and 6 were proposed with buildings spanning over the wetland complex. While the applicant believes that incorporating restoration practices near the built environment could be an important tool for education while simultaneously providing significant environmental benefits to the current aquatic system, the applicant understands that these two BDA features were causes of concern for the Corps and DWR. 145 7t' Avenue West, Suite B Hendersonville, NC 28792 828-698-9800 Tel SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 2 of 12 • Entrance road was realigned resulting in the elimination of stream impact S2 and wetland impacts W2, W3, and W4. This reduced stream impacts by 10 If (0.001 ac) and wetland impacts by 0.026 ac. • Entrance road grading was also altered to eliminate wetland impact W1. This reduced wetland impacts by 0.003 ac. • An additional development road was added (Figure 5a) and includes a 20 If (0.001 ac) culvert (stream impact S31). Impact S31 is proposed to access additional cabin sites. • The discrepancy in stream impact number S1 has been corrected. • The applicant is proposing to mitigate for impacts to streams associated with the road crossings and BDA features. The on -site conceptual stream mitigation plan for Hopewell Branch is discussed below. A map of the stream restoration location is included as Attachment F.

PROJECT PURPOSE The purpose of the BDA — Wetland Complex is to provide an amenity that will be a demonstration Stage 0 (zero) Stream Restoration. In addition, new culvert crossings are proposed to provide road access across streams on -site. The BDA demonstration project is designed to mimic natural processes from native beaver habitat that used to be prevalent throughout North Carolina and will provide ecological uplift for the aquatic systems on -site. Because the stream/wetland impacts are considered an amenity and because the Corps and DWR have raised concerns about the location adjacent to the school, the applicant is proposing traditional compensatory stream mitigation on Hopewell Branch that meets the Corps 2013 stream Mitigation Guidelines. Mitigation is discussed below (Attachment F). The development of the School of Wholeness and Enlightenment (SOWE) has a dual-purpose. The first is to develop a residential education and training center that will serve as a place where SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 3 of 12 people will be able to step out of their daily lives to establish a deeper state of peace, harmony, and balance at a cellular level of being with themselves and the Earth. The second is to enhance the physical, chemical, and biological integrity of the proposed campus through ecological restoration projects. The SOWE envisions a transformation of their land from a series of degraded streams and abandoned fields into flourishing native habitat. Ecosystem enhancements and restoration projects support the overall mission of SOWE, which is to provide a supportive environment where visitors can work on self-improvement based on an enlightened and harmonious relationship with the Earth. This demonstration project on the property will provide educational opportunities and serve as a demonstration project for BDA's in North Carolina by using this relatively new evolution of stream restoration practices. SOWE is including solar photovoltaic, geothermal, rainwater harvesting, and innovative stormwater management approaches to the infrastructure as examples of sustainable and regenerative technologies. REASONS FOR DISCHARGE BDA installations will serve to enhance the chemical, biological, and physical integrity of surface waters and wetlands on the proposed campus. BDAs will foster the truest to natural design available for this project site with the highest level of ecological benefits sustained. Additional impacts will involve two new culvert installations for stream crossings. The new stream crossings are associated with the construction of a new road network that is necessary to access proposed SOWE structures and cabins. Culvert removals and non -compensatory restorations and/or enhancements are also planned both within proposed BDA inundation areas and outside of BDA areas. Compensatory mitigation is discussed below. RESPONSES TO AGENCY COMMENTS The following section provides responses to comments and questions provided by NCDWR, CORPS, and NCWRC. NCDWR - Are BDA's appropriate here? CORPS - provide case studies or other research regarding beaver reintroduction in the Mountain Region and watershed size to support this restoration/ecological uplift strategy. We interpreted this question to also mean left to their own devices, would beavers build here. To answer that question RDE made an informed inference. RDE studied the existing and proposed forces at play at this site. In RDE's work to manage and restore water resources, RIDE strives to emulate and catalyze the natural processes of self -renewing ecosystems. RDE seeks to discover, characterize, and address the root causes of impairments. Understanding the history of the watershed, floodplain, and region helps to characterize and quantify the past and current movement of water, sediments, organisms, carbon, and nutrients into, within, and out of the system. We work to describe the evolutionary trajectory of a waterway if nothing were done, to elucidate the natural processes that would unfold over a significant timescale. Understanding the past and current management of beavers in this community is crucial to this approach. SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 4 of 12 There is a misguided but systemic belief among landowners across the southeastern United States that beaver activity should be harshly managed. This is usually through extirpation. Every year, the state of North Carolina harvests over 10,000 beavers (Source: https://www.ncwildlife.org/Learning/Species/Mammals/Beaver2#44731356- management). This number shows the ongoing and intentional efforts by state officers and landowners to reduce the population and habitat extents of this keystone species. RDE has observed evidence of beaver activity along Hopewell Branch and along Lower Thomas Branch, but these fledgling communities of beaver have not been allowed to flourish and expand their habitat. This is not to say that all beaver management is misguided. Instead, please note that if we let beavers work instead of continuing the culture of extirpation, the beaver would transform our waterways across the southeast. So, it is RDE's opinion the BDA's are appropriate at this location. NCDWR — Why BDA's in this specific area? RIDE evaluated "what areas are good locations for Beaver Habitat?" There are three unavoidable and necessary conditions for beaver habitat: • water that can be impounded, • vegetation that can support dam construction and nutrition requirements, and • an acceptable mix of geology and terrain. Water and vegetation will be available. Given that the first two bullets will be available, RDE's assessment focused on the last bullet: geology and terrain. Productive Beaver meadows take advantage of wide valleys with mild longitudinal terrain and fertile soils. Obviously, this setting also lends itself to agriculture and other human development, and that is precisely what has happened here and most other places across Madison County. These areas of topographic relief present an opportunity. Traditional land management emphasizes stormwater conveyance and stream manipulation and stabilization for land productivity and flood control. The cumulative result of traditional stream management has been to create stream corridors — which is defined as including channels and floodplains (Harvey and Gooseff 2015) — that are relatively simple and spatially homogeneous in form and process. As an alternative to this homogeneous conception of a stream corridor, the metaphor of a string of beads has been invoked, referring to retention zones within a river network that typically occur within wider, lower gradient segments of the river valley. This "string of beads" idea is explored in greater detail within our Project Justification and Design Narrative (Attachment A), and even more thoroughly in the literature. For example, in this excellent paper by Wohl et. al (2017).' Deciding where to put resources into restoring these "beads" is an ongoing topic of research. As with other forms of restoration with large wood, guidelines have been developed for identifying suitable beaver habitat and for emplacement of beaver dam analogs. As reviewed in several publications (e.g., Howard and Larson 1985; Olson and Hubert 1994; Gurnell 1998; 1 https://sites.warnercnr.colostate.edu/fluvial-geomorphology/wpcontent/uploads/sites/53/2016/05/10.1007_sl0533-017-0397-7.pdf SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 5 of 12 Baker and Hill 2003; Pollock et al. 2017), beaver exhibit preference for certain habitat characteristics. Among these are: • proximity to a water body or the ability to create a water body; for example, by damming seeps and springs; and • sand size or finer bed and bank sediment, as opposed to boulders or bedrock; and • availability of preferred deciduous woody plants, including willows (Salix spp.), aspen (Populus spp.), cottonwood (Populus spp.), birch (Betula spp.), alder (Alnus spp.), and maple (Acer spp.). At the future site of SoWE, there are only two areas along Hopewell Branch and Thomas Branch that may exhibit the above characteristics and the eventual development of a stream - wetland complex. RIDE is proposing BDAs in these areas. The Beaver Restoration Assessment Tool (BRAT) is the most high-tech planning tool available. BRAT is intended to help researchers, restoration practitioners, and resource managers assess the potential for beaver as a stream conservation and restoration agent over large regions and watersheds. This tool was not explicitly deployed in the planning for this project, but RIDE mentions it here to say: RIDE has a highly educated idea where BDAs will work, and RIDE has tools to guide the site selection of BDAs. References for the BRAT project is included as Attachment I. DWR - Can BDAs (or any restoration project) be an amenity for adjacent development The definitions of amenity and restoration are not well defined, but the project defines these as the following: • Amenities are desirable or useful features, something that helps to provide comfort, convenience, or enjoyment, usually in reference to residential or other real estate settings. • Restoration is assisting the recovery of ecological integrity in a degraded system by reestablishing hydrologic, geomorphic, and ecological processes, and replacing lost, damaged, or compromised biological elements. The existing conditions at the SoWE property consists of degraded streams and abandoned agricultural fields. Restoring these features, and indeed building around them to view the restored habitat can be viewed as an amenity, but that does not disregard the recovery of ecological integrity. Even if the project falls short of a regulatory mitigation definition of mitigation, that should not discount the significant ecological uplift that is being provided above current condition. The School of Wholeness and Enlightenment (SoWE) envisions a transformation of their land from a series of degraded streams and abandoned agricultural fields into flourishing native habitat. If their motives are not "pure" it is only because they do not want to foster this naturally beautiful aesthetic within a vacuum of wilderness without humans in it. Rather, they would put the natural landscape and the wildlife it attracts on full display to visitors of their proposed campus. SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 6 of 12 DWR - How will maintenance conflicts be managed between the BDAs and the built environment? RDE has developed a detailed Operation & Maintenance Manual (Attachment B) for the perpetual care of the stream -wetland complex. Maintenance conflicts are expected, but this manual describes a monitoring and management regime that will empower SoWE staff and contractors to manage these conflicts in a manner that maintains the habitat's ecological integrity. This manual is applicable across the SOWE campus and is adaptable over time. The prioritized goals of this manual are to: 1) support water quality improvement, 2) provide forage and shelter for wildlife, and 3) provide beautiful and inspiring scenery. DWR - Can the same habitat goals be achieved using natural channel design principals? River restoration efforts typically focus on the geometry of channels with the goals of reducing and then balancing sediment loads at the reach scale, effectively attempting to turn every reach into a sediment transfer zone. This perpetuates a single-minded approach to management of the alluvial channel system and may partially explain why the regeneration of high -quality habitat remains limited (Doyle & Shields 2012) and restoration of freshwater ecosystems remains elusive (Bernhardt & Palmer 2011). The goal of this project is to create a stream -wetland complex, a form that is naturally occurring and likely existed here before human settlement. In contrast, a regulatory based natural channel design approach would propose a rigid and channelized system. However, because both the Corps and DWR have expressed concern over these habitat goals, the applicant is providing a traditional stream mitigation plan (described below) to account for stream impacts. The stream mitigation plan will follow the Corps of Engineers 2013 Mitigation guidelines for Stream restoration. As a result, the property will have a demonstration regulatory influenced stream restoration project and a demonstration stage 0 restoration BDA-based system. The applicant looks forward to monitoring, evaluating, comparing, and reporting measurable attributes of both. Corps — On -site Alternative option 3 (amenity ponds) states that the development of such ponds is "contrary to the mission of SOWE." However, initial project proposals included construction of such ponds and subsequent proposals include open water areas that are constructed under the auspices of ecological restoration. Option 3 of the alternative analysis was presented as an option to the owner. As previously stated, development of such ponds (e.g., traditional earthen dams) may have negative effects on stream temperature, aquatic passage, and water quality. The pond in on -site alternative option #3 was rejected for this reason. As was documented in a previous submittal, only a small portion of the BDA complex will be open water, and most of the area will consist of a vegetated wetland complex. Additionally documented in immense detail (Attachment A — Project Justification and Narrative), is the significant ecological benefits that can result from BDA complexes. These benefits do not occur with a traditional dam/pond.

Please refer to Attachment H for a detailed response from RIDE to each of the comments provided by WRC. IMPACTS The impacts proposed in the SOWE campus include culvert impacts associated with development of a new road network, fill and inundation impacts associated with the installation of BDA features, culvert removal and restoration impacts, and stream enhancement impacts. The proposed impacts will affect Thomas Branch, unnamed tributaries to Thomas Branch, Hopewell Branch, unnamed tributaries to Hopewell Branch, and wetlands associated with each stream. There are approximately 2,062 linear feet (0.161 acres) of impacted stream and 0.022 aces of impacted wetland (Figure 5b-5f). Individual impacts are as follows: TABLE 1.0 WETLAND IMPACTS Wetland impact Type of number Type of impact Type of wetland Forested jurisdiction Area of impact Permanent (P) Corps (404,10) or (acres) Temporary (T) DWQ (401, other) W1 — P IMPACT REMOVED FROM PROJECT W2 — P IMPACT REMOVED FROM PROJECT W3 — P IMPACT REMOVED FROM PROJECT W4 — P IMPACT REMOVED FROM PROJECT W5 — P IMPACT REMOVED FROM PROJECT W6 — P *Other Bottomland Yes Corps 0.007 BDA HB4 Hardwood Forest W7 — P Fill Bottomland No Corps 0.002 BDA T134a Hardwood Forest W8 — P *Other Bottomland No Corps 0.013 BDA T134A Hardwood Forest W9 — P IMPACT REMOVED FROM PROJECT *Impact quantities designated as "other" represent the maximum possible extent of inundation from the BDA structure.

STREAMBANK STABILIZATION & ENHANCEMENT Approximately 480 If of Thomas Branch (Impact S30; See Figure 5D) below TB BDA #2 are planned for stream enhancement. The purpose of the proposed enhancement is to provide a floodplain bench and stable banks. This work is not being done for mitigation credit. The wetland at the lower end of the enhancement reach just upstream of the cul-de-sac will not be impacted by the stream enhancement project. ROADS Total impacts to streams and wetlands on the project associated with road access and crossings totals 0.005 ac (61 If) and 0.000 ac of wetlands. ON -SITE COMPENSATORY MITIGATION — HOPEWELL BRANCH SOWE proposes to compensate for impacts in the Permitted Area through Permittee Responsible Mitigation (PRM). PRM will occur within the project boundary. The mitigation will provide 828.5 If of mitigation and consist of stream enhancement, stream restoration, and stream preservation along sections of Hopewell Branch. The mitigation project will begin immediately below the BDA (HB4) on Hopewell Branch and extend south to the property line. Results from the North Carolina Stream Assessment Method (NCSAM) and Wetland Assessment Method (NCWAM) are available in Attachment G. The mitigation will be performed in accordance with North Carolina stream mitigation guidelines which has been promulgated by the Wilmington USACE Regulatory District. Upon regulatory review of the on -site conceptual mitigation (Attachment F), RDE will prepare a final mitigation plan for review and approval. Final approval of PRM by SOWE for this project is conditioned upon the approval of this application by USACE and other applicable permitting agencies. The required amount of mitigation is also subject to agency approval. Wetland impacts for the entire project total 0.022 acres of impact; therefore, no wetland mitigation is proposed. Table 3.

SAW-2020-00632; DWR No. 2020-1654 January 27, 2022 Page 11 of 12 STORMWATER The overall site response regarding stormwater and drainage is to use an Integrated Water Resources Plan for the project that integrates natural patterns of hydrology into the site master plan. This approach will allow for a sustainable response regarding stormwater measures while emphasizing opportunities to harvest rainwater, reduce stormwater runoff, replenish groundwater resources, and enhance ecosystems and biodiversity. Additional measures for the reduction of impervious surfaces are also part of this low impact development and the project will not use curb and gutter anywhere on the project so they can treat and convey stormwater via vegetated swales and rain gardens. For the reception center and guest parking lot, Mercer Design Group will be submitting any stormwater plans directly to the NC DWR Raleigh office by February 25, 2022. A copy of these stormwater plans will also be sent directly to Ms. Chonticha McDaniel and Ms. Sue Homewood, DWR. Stormwater treatment from this parking lot will incorporate the use of permeable pavement and biofiltration. The current reception center and parking site plans indicate 34,248 Square Feet (SF) of permeable paving at the parking spaces; 21,601 SF of impervious asphalt for drive aisles; 1,751 SF of permeable pavers at the reception center entry; and 2,081 SF of permeable pavers at walkways and drive aisle transitions. The total area of paved surface at the reception center and 100-car parking area is approximately 59,681 SF, with 38,080 SF (64%) of that total being pervious surface. THREATENED & ENDANGERED SPECIES Multiple biological surveys were conducted at the proposed SOWE campus as part of the project due diligence and include: Wildlife Biodiversity Assessment conducted by Conservation Ecology LLC, Ecological Assessment and Botanical Inventory conducted by Mountains to Sea Ecological, and Evaluation of Potential Summer and Winter Habitat for Gray Bat conducted by Skybax Ecological Services. An addendum to Wildlife Biodiversity Assessment conducted by Conservation Ecology LLC for bald eagle observation was issued to include an effects determination of "not likely to affect" for bald eagle. These reports were provided to the Corps in the original permit application submitted February 1, 2021, or in a response to agency comments dated July 19, 2021. It is our opinion that the applicant has satisfactorily addressed the concerns raised by these agencies, including Section 7 requirements. CULTURAL RESOURCES ClearWater consulted with the North Carolina State Historic Preservation Office Data Explorer (HPOWEB 2.0). The project site is not within 2 miles of any Historic resources on the National Register. Additionally, ClearWater sought concurrence from SHPO on March 04, 2021.

EXECUTIVE SUMMARY The School of Wholeness and Enlightenment (SoWE) envisions a transformation of their land from a series of degraded streams and abandoned agricultural fields into flourishing native habitat. If their motives are not pure, it is only because they do not want to foster this naturally beautiful aesthetic within a vacuum of wilderness without humans in it. Rather, they would put the natural landscape and the wildlife it attracts on full display to visitors of their proposed new campus. Robinson Design Engineers (RDE) finds the project goals commendable, and we are proud to serve as the liaison to these efforts. Currently, the streams on SoWE's property are narrow, racing trickles, and even when these streams emerge from confined, gorge -like valleys into valley flats, the channels remain simplified and homogenous and disconnected from their floodplains. This is not a new condition, nor sadly is it a unique case. Even if all human activity in the watershed ceased today, the streams on site would evolve through a slow adaptation to legacy effects of land use, cycling through further degradation and widening. Riparian corridors would suffer increasing levels of Riparian Hydrologic Drought, and it would take many human lifetimes before wetlands would expand, riparian zones would flourish, and the streams would sustain themselves as sediment sinks instead of sediment sources. At SoWE, we have a unique opportunity to repair stream to land connectivity, even as human activity within the watershed increases! The broad and flat terrain near the confluence of Hopewell and Thomas branch is ideally suited for a wetland -stream complex using biomimicry of one ecosystem engineer's formerly ubiquitous handiwork. Anastomosing streams flowing through dense wetland areas and buffered by wide riparian corridors, known as Stage 0, prevailed for eons, as they were designed and sustained by Castor canadensis carolinensis, the carolina beaver. Rewilding beaver colonies is problematic in most of the developed world for societal reasons, but not on ecological grounds. As an alternative to beaver reintroduction, many practitioners across the globe are emulating this master builder by establishing "Beaver Dam Analogs" (BDAs) that generate food and forage supporting the life cycles of plants, animals, and other living things coevolved to the patch dynamics fostered by this keystone species. Broad valleys with productive soils are naturally scarce in Madison County, and because they are scarce, they have been preferentially developed for agriculture or transportation infrastructure. Proposing BDAs and the Stage 8 restoration approach is only possible because SoWE is relinquishing these valuable flatlands from development. The intent of the BDAs on this project site is to enhance the physical, chemical, and biological integrity of the surface waters and wetlands to be featured as an attraction for visitors to the School. An obvious co -benefit of this project approach is that it will slow the flow of water, passively rebuild stream beds and banks, phytoremediate runoff, and provide habitat that enhances Waters of the US held in the public trust. The inevitable result of BDAs is the sustenance of streams and expansion of wetlands. In this way, the project approach effectively removes the stream corridor from future development. In our experience, Natural Channel Design methods tend to offer a short cut to decreased sediment transfer rates in the short term, yet they are at high risk for failure and tend not to deliver long term habitat improvements. Here at SoWE, we have an unusual opportunity to work with pioneering clients to develop the land with integrity and leave it better than we found it. Based on our research experience and observation of beaver in their natural environment, we feel confident that BDAs will foster the truest to natural design available for this project site with the highest level of ecological benefits sustained. 2. LAND USE LEGACIES Legacy effects of rapid sediment exchange caused by forest clearing and agricultural cultivation, affecting both uplands and valley bottoms, drastically altered the southeastern landscape, primarily over the course of the early 19th to early 20th centuries (Trimble 1975; Jackson et al. 2005; Walter & Merritts 2008; Wohl 2019; Ferguson 1999; Dearman & James 2019). Hugh Hammond Bennett, who grew up in North Carolina's Piedmont amongst row -cropped tobacco farms, wrote prolifically over the course of the 1930's to draw national attention to the degradation of his southeastern home: "This paper is not primarily concerned with the effects of normal or natural erosion, except as a basis for comparison. It pertains to changed physical, chemical, and biologic conditions resulting from abnormal erosion, the accelerated soil washing following man's activities, his free use of axe and plow and the overcrowding of live stock upon sloping ranges" (Bennett 1932, pg. 385). It was Bennett who secured federal funding to establish the Soil Erosion Service, which became the Soil Conservation Service, now known as the Natural Resources Conservation Service (NRCS) (Helms 2008; Sporcic & Skidmore 2011). Missing from the forest floor, missing from the valley bottoms, untold volumes of topsoil forever lost, wasted away, carried off downstream and buried under yet another blanket of eroded deposits — the infertile subsoil, friable parent material, weathered rock, and jagged gravel pieces exposed when the forest floor vanished. All of this missing water holding capacity, not to mention plant available nutrients and the microorganisms that make it so, have forever changed the hydrogeomorphic processes at work in this landscape, shown in Fig. 1 below in a soil map from 1942 checkered with varying designations of `accelerated erosion,' which is to say, anthropogenic process disruption. f: r 10 H C�- ACCELERATED EROSION Moderate sheet erosion Severe sheet erosion Moderate gully erosion Severe gully erosion Moderate sheet and gully erosion Gully Fig. 1: The map above has been adapted from the Soil Survey of Madison County by Goldston et al. (1942a) to highlight the project area (roughly circled) and includes the part of the legend referring to accelerated erosion. The soil scientists who mapped Madison County in the early 1940's have this to say about the conditions of mountain streams in the region: "As a whole, Madison County is rough and rugged, as most of the mountain slopes are very steep — in some places precipitous. The streams have played a major part in making the relief what it is today. In places they have cut valleys several hundred feet deep, and in some places these valleys, or gorges, are flanked by precipitous walls. [... ] Streams have dissected these low, steep hills so badly that comparatively little level land remains. [... ] Slopes to streams are steep, and only in very few places does any bottom land occur at the foot of these slopes or along the streams. [... ] The streams have thoroughly dissected the Blue Ridge Plateau. They have cut very narrow V-shaped valleys and gorges and have created an extremely rugged land form. Drainage is good to excessive. The streams are swift and transport large quantities of material." (Goldston et al. 1942b, pg. 3 - 4) The legacy effects of land use are still in evidence on the property today. Where native hydrophilic vegetation is able to reach deep to the water table lowered to meet the base level of incised streams, roots dangle from cut banks and will soon crumble and fall into the flow, if they haven't already (Fig. 2A). Such slumped material, jagged gravel pieces, and steep banks are all too familiar to us. Gullies are on nearly every site we visit. Some portions of the streams look little better than excavated roadside ditches. The lawn is kept closely clipped on either side, and the presence of grass is in and of itself an indication the stream is currently unable to support obligate wetland plants (Fig. 213). Fig. 2: These photos depict streams visited in August of 2020 on the project site. The photo on the left (A) shows Hopewell Branch and demonstrates how incision triggers Riparian Hydrologic Drought. The photo on the right (B) shows Thomas Branch hardly able to sustain basef low. Shifting Baselines Syndrome (SBS) is a term that describes a phenomenon concerning regulatory standards of ecosystem management. Stemming from fisheries science, where regulations such as catch limits are established with a recent past condition set as the standard for return to a state of equilibrium, misremembered prior conditions often result in successive lowering of expectations through `generational amnesia' over human lifetimes, as the impairments of one generation are adopted as baselines of the next (Campbell et al., 2009; Papworth et al. 2008). Generational amnesia seems an apt diagnosis regarding society's expectations of stream form and function in the southeast, as the Carolinas establish Reference Hydraulic Geometry Curves, or design stream dimensions based on regression curve analysis of `reference condition' channel form. This method of comparative analysis, while useful for understanding trends between a watershed's drainage area and response variables of channel slope, width, depth, etc., could dictate prescriptive stream form measurements that do not take into account the highly variable landscape context of mountain streams and the omnipresent, underlying co -morbidities impairing them, not to mention the wide error bands recognizing variation along the fitted regression equation. How would it look and feel to restore and conserve these relatively flat alluvial systems? Historical evidence and recent scholarship strongly suggest that this hydrologic landscape should be a sluggish, productive backwater marsh, created by a pleasingly -messy series of small and frequent beaver dams. Here, in this mountainous Madison County context, that would mean willow, birch, and other native riparian trees would ring upstream areas of the marsh; dead and down trees would stand a slant in its chesty backwater, providing perches and nesting cavities for birds and bats. If you plodded into the ponded water your step fall would sink into silt and leaves. The sweet smell of decomposing organic material would waft through the air. Heterotroph invertebrates of this system, so-called "shredders", 8 can be five times more abundant in this habitat than in single -thread channels. Because of the topographic complexity and the tenacious vegetation, the ponded water would frustrate anglers, but native fauna would thrive. Warblers, sandpipers, and flycatchers would perch in the overhanging willows; peepers (frogs) would provide a twilight symphony, croaking along the marshy aprons; the deep, cool pools and refuge channels would provide abundant trout shelter; and otters may eventually chase these trout through the submerged branches of downed trees. To recover this waterway to pre -settlement conditions is impossible. To stabilize it and keep it just the same as it is today by using, for example, `natural channel design,' would be to preserve a blighted system. The overarching goal of our work is to repair the disconnected valleys and simplified streams by fostering conditions that can support a thriving wetland complex and the positive feedback loops unleashed by working with, not against nature. This work will restore natural processes that slow the flow of water, increase floodplain soil fertility, enable hyporheic groundwater exchange, and provide suitable habitat for the return of rare mountain wetland plant species within the perpetual care of an environmentally conscientious land stewardship program at SoWE. This design narrative presents our research to provide justification that Beaver Dam Analogue structures (BDAs) are the most promising means to accomplish the goal of restoring these streams into their native and natural state — a stream -wetland complex. This narrative also presents our design approach to building these wetland complex systems, outlines regulatory considerations, and provides schematic design drawings, example materials, and case studies to help guide the project. We recognize that the approach we are taking using BDAs is novel in the Carolinas, but rest assured, it is nothing new, and it is being implemented successfully across the nation. 3. PROJECT JUSTIFICATION In 2003 Glen Albrecht, an Australian philosopher, coined solastalgia, a word for the emotional distress we feel at witnessing the destruction of beloved homelands. Albrecht's neologism, which drew from the roots for comfort and pain, had its origins in the territory of New South Wales, where open -pit coal mining destroyed hundreds of square kilometers and inflicted deep psychic wounds on residents. In four syllables solastalgia captured the Anthropocene and its discontent: the dissonance of change, the rapidity of loss, the disorientation wrought by environmental grief. Solastalgia, simply put,'Albrecht wrote, is `the homesickness you have when you are still at home "' (Goldfarb 2018, pg. 239) Land development typically limits undisturbed natural areas to the fringes of parcel boundaries, so that scrappy wilderness patches are normal and expected. Instead of this usual development pattern, the School of Wholeness and Enlightenment (SoWE) aims to integrate the preservation of natural areas into every aspect of the campus it has envisioned. We commend the architect's vision to first restore the land, unlock its natural beauty, and then build human interfaces within these natural systems. We have been working closely as a team during the design process to foster a rare relationship at SoWE. Instead of subjecting the existing conditions to suit the built environment, this project Sandalone Creek Upper Black Creek Lower Black Creek TN V 100 m E seeks first and foremost to develop a flourishing natural environment, and then to thoughtfully tie in the human infrastructure. The form of a stream is an expression of the history of the surrounding landscape (both natural and anthropogenic) and regional climatic variables, which influence the mass balance of water, sediment, and organic material transferred from the contributing drainage area into valley bottoms, shaping waterways (Knighton 1984; Julien & Raslan 1998; Brooks et al. 2012; Kasprak et al. 2016; Leopold et al. 2020; Wohl 2020). Few of these factors remain static, and fluctuations in water, sediment, and wood affect stream form both along a spatial and temporal continuum. Montgomery and Buffington (1997) note that unlike low -gradient stream networks, high- energy mountain drainage basins are prone to external forcing by constraints such as confinement within a narrow valley, shallow bedrock outcroppings, natural woody debris pileups, and the influence of anchoring riparian vegetation, all of which force morphologies that would otherwise, in an analogous unobstructed flow pattern, take on the morphology of a higher energy system. Studies conducted in the Pacific Northwest demonstrate that log jams and woody debris pileups have the capacity to create aggradational deposits over streams that would otherwise flow across exposed bedrock and that the systematic removal of these naturally -accumulating obstructions have reduced backwater sloughs, side channels, and meandering headwater tributaries to a more simplistic single -threaded planform (Montgomery et al. 1996; Sedell & Froggat 1985, see Fig. 3). Wohl (2013) suggests that research conducted in the Pacific Northwest offers insight into the role beaver once played in shaping North American rivers, as most thorough fluvial geomorphic investigations have occurred in streams that suffered deforestation, beaver extirpation, and obstruction removal long before the scientists arrived to study them with contemporary quantification methods. ♦ EHarrishurg � M pl ' � a J� rg d I r d C ` Q e r 1 �r F 4 McKan zle River F V' 1B54 1910 1946 1967 Fig. 3: On the left, a diagram from Montgomery et al. (1996) depicts stores of sediment (grey hatching) raising stream beds behind natural debris jams (marked as an X). On the right, Sedell & Froggatt (1984) depict the loss of planform heterogeneity to the Willamette River in Oregon over time. m A contentious debate within the field of river restoration in the US hinges on one classification system, the Rosgen classification system and method of `natural channel design' (Malakoff 2004; Kondolf 2006; Simon et al. 2007; Rosgen 2008; Simon et al. 2008; Lave 2008). Kasprak et al. (2016) found that Rosgen's Classification system aligned well with the River Styles Framework of Brierly and Fryirs (2013), popular in Australia, but that both classification systems failed to accurately predict processes in streams with significant anthropogenic disturbances and biotic controls, such as beaver activity and cattle grazing. Nevertheless, aspects of Rosgen's method have become so entrenched in the regulatory permitting process for stream restoration, compliance is all but mandatory, as other restoration methods have adopted aspects of Rosgen's approach. River restoration efforts typically focus on the geometry of channels with the goals of reducing and then balancing sediment loads at the reach scale, effectively attempting to turn every reach into a sediment transfer zone. This perpetuates an erroneous approach to management of the alluvial channel system and may partially explain why the regeneration of high -quality habitat remains limited (Doyle & Shields 2012) and restoration of freshwater ecosystems remains elusive (Bernhardt & Palmer 2011). Conceptual frameworks for understanding the spatial and temporal processes affecting stream geometry and its effects will be discussed in this section on Project Justification, including the concepts of stream evolution, process domains, and connectivity. Within these concept clarifications, we offer corresponding limitations to Natural Channel Design. We conclude this section with specific justification for mimicking beaver activity as a water resource conservation and enhancement project. This context will provide a foundation for the next section on our Design Approach, which proposes an intervention that is built to recover within the recurrence intervals of natural and anthropogenic disturbance regimes (e.g. storms and construction), rather than to rigidly hold form in spite of inevitable changes and disturbance within the watershed, as Natural Channel Design methodologies would. 3.1 The Stream Evolution Model Schumm's (1997) Channel Evolution Model (CEM) provides a framework for stream form alternatives by helping to predict the natural evolutionary sequence of streams as they adapt to disruptions both natural and anthropogenic. Assumptions inherent in Schumm's Channel Evolution Model (CEM) include the Stage I precursor form, which presupposes that undisrupted streams have a single -threaded planform; whereas growing evidence suggests that single -threaded channels are a symptom of beaver extirpation, natural debris obstruction removal, and active straightening, or channelization, of streams, and do not adequately describe the precursor stage of undisrupted streams which would exhibit an anastomosing or braided planform of wetland complexes and vegetated isles interrupting and separating streamflow (Naiman et al. 1988; Walter & Merritts 2008; Wohl 2013; Cluer & Thorne 2014; Pollock et al. 2014; Goldfarb 2018). Cluer & Thorne (2014) adapted Schumm's CEM to incorporate this relatively recently understood precursor stage (Stage 0 Anastomosing) and provide further detail on complex responses of streams to anthropogenic disruptions of mass balance equations of sediment, water, and wood in m streams — the Stream Evolution Model (SEM). Another important difference in Cluer & Thorne's (2014) expansion on Schumm's concept is that they have redrawn the progression of stages into a cyclical, not linear progression, where Stages 0 — 4 can become stuck in a feedback loop not unlike a "short-circuit," where downcutting and widening can be triggered over and over again (see Fig. 4). s]ac E o ANSlwrewy M,a[eme..N wA[ w.Amane STAGES STAGEI ANI{OIIgN+t= fl.Wpur SI.rEI.

Dashed arrows indicate `short-circuits' in the normal progression, indicating for example that a Stage 0 stream can evolve to Stage 1 and recover to Stage 0, a Stage 4-3-4 shortcircuit, which occurs when multiple head cuts migrate through a reach and which may be particularly destructive. Arrows outside the circle represent `dead end' stages, constructed and maintained (2) and arrested (3s) where an erosion -resistant layer in the local lithology stabilizes incised channel banks. The Stream Evolution Model & Limitations of Natural Channel Design The channels in most alluvial reaches are restored from Stage 3 to Stage 6 forms in the Stream Evolution Model (SEM, see Fig. 4). These relatively low value forms are then preserved through contrived stabilization measures. In a recent webinar, Colin Thorne suggested that another `arrested' stage could be included as an offshoot to Stage 6 (Quasi -equilibrium) where restoration activities halt lateral activity at Stage 7 through biotechnical revetments of beds and banks, just as with Stage 3a (Thorne 2020). The only way out of this short-circuit cycle of degradational process, according Cluer & Thorne (2014), is through the eventual longitudinal gradient stabilization of sufficient degradation and widening at Stage 5 for the stream to recover a terraced floodplain of alluvial deposition inset in the large, degraded former channel boundaries. This hypothesis is 12 supported by the literature on stream competence, as for example, Montgomery & Buffington (1997) point to the availability and limitations of sediment supply as a driving factor in the form a stream takes. Even though using soft engineering and natural materials such as biotechnical revetments and large wood have become common, stabilization impedes the fluvial processes that could drive continued evolution to the substantially more resilient and ecologically valuable Stages 7 and 8.

The relative size of the circles represent the ordinal points achieved at each stage relative to the maximum achievable points, where a high rank represents `abundant and fully functional' and a low rank signifies `absent or dysfunctional'. This conceptual framework of ecosystem benefits and physical attributes demonstrates that a return to pristinity at Stage 0 is impossible; that to freeze forms at Stage 2 or Stage 6 (the target of most Natural Channel Design methods) misses enhancing benefits; and that late adaptations to Stage 8 offer the closest possible return to pre -settlement conditions and the highest level of habitat enhancement represented by Stage 0. Cluer & Thorne (2014) diagram conceptual benefits of stream processes throughout the evolutionary trajectory of dominant process (see Fig. 5). Whereas Rosgen's `natural channel design' methodology seeks to freeze streams into a rigid Stage 6 form of `Quasi Equilibrium,' we have the capacity to usher surface waters towards a Stage 8 Anastomosing' stream form with higher benefits to habitat and ecosystem attributes, according to Cluer & Thorne's (2014) analysis of stream form and function. The channels on SoWE property are at stages 2 and 3 as described by the SEM diagram (Figure 4). As the SoWE campus is built and the watershed continues to develop, these channels will experience the predictable progression to stage 3a (arrested degradation) or a stage 3-4-3 short circuit of degradation and widening. Degraded channels like these are 13 sadly all too common and are a source of solastalgia for the initiated. Polvi et al. (2011) demonstrate that entrenched stream channels limit the width and frequency of riparian inundation, having measurable impacts on the health and spread of riparian corridors. Cluer & Thorne (2014) describe the relative benefits of each stage of the SEM, demonstrating that this concept for a Stage 8 channel will facilitate multiple aims of habitat enhancement. 3.2 Process Domains The existence of process domains implies that river networks can be divided into discrete regions in which ecological community structure and dynamics respond to distinctly different physical disturbance regimes (Montgomery 1999). Wohl (2020) provides a comprehensive literature review exhibiting the usefulness of categorizing process domains along a river network. By delineating these process domains we can understand spatial patterns of riparian vegetation (Polvi et al. 2011), sediment dynamics (Wohl 2010), organic carbon stock in river corridors (Wohl et al. 2012; Sutfin and Wohl 2017), aquatic ecosystem dynamics and biodiversity (Bellmore and Baxter 2014), channel geometry (Livers and Wohl 2015), and connectivity (Wohl et al. 2019). Some river geomorphic parameters exhibit progressive downstream trends whereas others exhibit so much local variation that any systematic longitudinal trends which might be present are obscured (Wohl 2010). Local variation that overwhelms progressive trends is particularly characteristic of mountainous terrain, where spatially abrupt longitudinal transitions in substrate resistance, gradient, valley geometry, and sediment sources can create substantial variability in river process and form. Under these conditions, characterizing river dynamics based on these longitudinal transitions can be more accurate than assuming that parameters will change progressively downstream. Examples of geomorphic parameters for which spatial variation is better explained by process domain classifications than by drainage area or discharge include riparian zone width (Polvi et al. 2011), floodplain volume and carbon storage (Wohl et al. 2012), connectivity (Wohl et al. 2019), instream wood load (Wohl and Cadol 2011), and biomass and biodiversity (Bellmore and Baxter 2014; Herdrich et al. 2018; Venarsky et al. 2018). Process Domains & Limitations of Natural Channel Design A geomorphic perspective on river resilience would characterize a resilient river as having two basic characteristics. First, a resilient river has the ability to adjust form and process in response to changes in water, sediment, and wood inputs, whether these changes occur over many decades to centuries (e.g. climate variability) or over relatively short time periods (e.g. watershed development or a large flood). This is an important distinction from a robust river system which must rigidly maintain one set of conditions in order not to fail. An artificially dammed river is robust. A beaver dammed river is resilient. The latter can be flexible to changing conditions and recover or be made stronger by disturbance, the former is at its best on the day of installation and only gets worse over time (see Graf 2001; Wohl 2004; Wohl & Beckman 2014). 14 Second, a resilient river has spatial and temporal ranges of water, sediment, and large wood inputs and river geometry similar to those present under natural conditions (Wohl 2020). Montgomery and Buffington (1997) distinguish source, transport, and response segments in reach -scale classification of mountain channel morphology. Sklar and Dietrich (1998) hypothesize consistent changes in dominant incision mechanism (e.g. headcuts) and substrate type (coarse -bed alluvial, fine -bed alluvial) at threshold slopes, regardless of drainage area. Natural Channel Design would presuppose that all streams on the project site should exist as sediment transfer zones, stabilizing beds and banks with boulders, rock toes, and other robust features resistant to high-energy flows. If instead, we acknowledge legacy manipulations to channel-floodplain connectivity, we can restore these channels to a resilient system that takes a lower -gradient process domain as its target. Where the streams emerge from confined valleys, the carolina beaver would have had an outsized effect on stream form and function. By emulating beaver and recognizing an opportunity to transition dominant processes, we should see Thomas and Hopewell transform into a lower -energy, diffuse storage area to capture the water, sediment, and wood we would expect to find in these broad valleys. 3.3 Connectivity Paradigm The spectrum of stream connectivity to disconnectivity (see Fig. 6) describes the longitudinal (upstream/downstream), vertical (surface water/ground water), and lateral (floodplain/instream) exchange over spatial and temporal scales, involving the movement of water, organic material, and sediment (Ward 1989; Montgomery 1999; Kondolf et al. 2006; Wohl & Beckman 2014; Wohl 2019). Connectivity is neither a priori better nor worse than disconnectivity, depending on constraints imposed by the natural context. A high - gradient mountain stream passing through a closely confined valley, for example, would exhibit lateral disconnectivity, but experience high longitudinal connectivity, exporting runoff, sediment, and organic material downstream. Conversely, an anastomosing stream would experience high lateral connectivity, delivering sediment, organic material and water to floodplains, but longitudinal connectivity would occur much more slowly in this diffuse energy zone. Water, Sediment, Wood, Salute, Animals Water, Sediment, wood, Solutes ■ Animals Water, Solutes, Animals channelization removal of large wood removal of beaver dams Lo flow regulation levees bank stabilization channelization floodplain drainage 15 Fig. 6: From Wohl (2019), this diagram demonstrates the concept of connectivity, the movement of water, sediment, wood, solutes, and organisms vertically between the atmosphere and groundwater, longitudinally from upstream to downstream, and laterally between a stream and its floodplain. Examples of anthropogenic disruptions to connectivity are offered next to the wavy lines breaking the arrows of connective transfer. Among the many challenges in managing rivers are those of quantifying connectivity and understanding how human activities have and will increase or decrease connectivity within a landscape (Kondolf et al. 2006). This connectivity ultimately reflects geomorphic context and governs the extent to which a river network or a reach of a river is integrated into its floodplain and the greater landscape. Geomorphic context includes spatial dimensions of river corridor geometry, location within a drainage basin, and location within a global context (Wohl 2020). High connectivity implies that matter and organisms move rapidly and easily within a river network. Landscapes typically include some characteristics that create at least temporary storage and limit connectivity. Subsurface units of low permeability can limit the downslope transmission of water from hillslopes to channels, or limit hyporheic and ground -water exchanges along channels (e.g. Gooseff et al. 2017). Lakes, broad floodplains with extensive wetlands, and numerous channel -spanning obstructions such as beaver dams and logjams can substantially decrease the rate at which floods move through a river network (e.g. Lininger & Latrubesse 2016; Wegener et al. 2017). Extensive and active floodplains increase the residence time of suspended particles, including sediment and soluble nutrients, within a river network, so that these basins have a greater capacity to store and filter whatever the water carries than streams without extensive floodplains or with inaccessible floodplains. liR Some river networks naturally have high levels of connectivity, whereas others include many features that limit connectivity (e.g. Burchsted et al. 2010; Mould and Fryirs 2017). The three dimensions of connectivity commonly have different relations to reach -scale characteristics: channel obstructions such as logjams and beaver dams, for example, promote lateral and vertical connectivity for water, solutes, and particulate organic matter, but limit longitudinal connectivity for these materials. High sediment inputs that promote channel avulsion and high rates of lateral migration may increase lateral connectivity for water, solutes, sediment, and large wood, but restrict longitudinal connectivity for these materials. Connectivity Paradigm & Limitations of Natural Channel Design Natural Channel Design conducted with the best of intentions retains the potential to become subsumed under the future heading legacy effects of hydromodification. Understanding the connectivity paradigm within the natural context of valley slope, stream segment, and underlying geology helps elucidate pathways to recovery where streams have long suffered human -induced impacts. The paradigm at these SoWE sites is similar to many other agriculturally manipulated and impaired floodplains in western North Carolina: increase in longitudinal connectivity (stream straightening), a decrease in lateral connectivity (drain floodplains for planting), and indirectly decreasing vertical connectivity (incision impacts ground -surface water interaction). The streams on the SoWE property flow through headwater valleys with relatively thin, narrow alluvial veneers over bedrock and then experience a drastic shift as they enter the broadest valleys on the property. Streams situated in valleys like these, on long-standing farmsteads, have assuredly been impacted through centuries of anthropogenic management. And, predictably, the more incipient soils in these areas will be the first to degrade, continuing their march through the Stream Evolution Model (SEM). However, these broad valley areas also present an opportunity. These areas are relatively flat and the finer grained soils are fertile ground for riparian trees and wetland meadow grasses. Using BDA techniques, these broad valley areas can be fast -forwarded into wetland complex systems; they will provide greater floodplain buffers and increased hyporheic exchange. The presence of these floodplain buffers will create depositional zones, and progressively more extensive floodplains providing greater average residence time of sediment, surface flow during overbank floods, and subsurface flow. Coarse and fine particulate organic matter will be sequestered within these wetland complex systems. 3.4 Beaver Hydrologic Habitat Contemporary research on log pieces and log jams as structural interventions capable of reversing stream incision has considerably influenced stream restoration methods in other parts of the United States. In the arid Southwest, for example, Beaver Dam Analogs (BDAs) and Post Assisted Log Structures (PALS), sometimes combined with beaver reintroductions, have significantly improved the hydrological and ecological functions of restored streams (see review Philiod et al. 2017). Many of these methods draw from designs adapted in the early 1900's by the USDA Forest Service and Soil Erosion Service 17 (see, e.g. Kraebel & Pilsbury 1934; Ayres 1936). While these practices have enjoyed a renaissance in the western US, their application to the unique environmental legacies of the southeast are underrepresented in the literature and in practice (Wohl 2019). Hand - built wooden structures offer tremendous potential to reverse stream incision in the Southeast by passively raising stream beds and reducing stress on banks. In the wetter conditions of the southeast, there is a chance that seasonally inundated riparian zones can become permanently flooded areas, as hyporheic exchange allows groundwater sources to connect depressional wetlands with additional water inputs. Beaver ponds have been shown to increase hyporheic exchange, buffering water temperatures (Weber et al. 2017) and influencing nutrient dynamics (Margolis et al. 2001; Bason et al. 2017). Riparian zones of beaver ponds have been shown to have denser above ground biomass compared to riparian zones of same or similar species composition in nearby unobstructed stream side zones (Gatti et al. 2018). The effects of beaver on the hydrologic condition of streams has rippling effects for the floodplain and the plant communities comprising them. As Naiman et al. (1988) demonstrate, some of these effects catalyze long-term successional processes, even if the ponds are abandoned and transform back into streams. By slowing the flow of water, beaver create positive feedback loops that allow vegetation to establish, which further decreases hydraulic stress (Box 2018). Beaver ponds create sediment sinks that build up stream beds, creating newly exposed areas for vegetation to establish (Osterkamp & Hupp 2010). The slower water allows sediment to settle raising the stream bed level, offering incising streams an avenue for reunion with its floodplain (Pollock et al. 2014). This latter mechanism is of particular interest to the southeastern region given the ubiquity of gullying in response to historic land cultivation legacies. Streams suffering from legacy effects of incision may experience a condition called Riparian Hydrologic Drought, where incision causes both fewer instances of floodplain activation achieved by overbank flows (decreased lateral connectivity), as well as a localized lowering of the water table near incised streams (decreased vertical connectivity) (Groffman et al. 2003; Hardison et al. 2009). In Fig. 7 below, Hardison et al. (2009) diagram the comparative lateral and vertical disconnectivity of incised stream channels. On the left, a cross section of a stream is depicted where vertical connectivity is demonstrated by the high water table saturating floodplain soils, and lateral connectivity is possible within the breadth of the bold arrows demarcating the floodplain. In the diagram on the right, stream incision is halted by the confining unit, as in Cluer & Thorne's (2014) SEM Stage 3s (see Fig. 4 above). Vertical and lateral disconnectivity is indicated by the lowered water table and narrowing of the `floodplain'. The effect this has is called Riparian Hydrologic Drought, a wilting of riparian corridors starved of nutrients and seeds delivered in floods and groundwater accessible to shallow rhizospheres of wetland vascular plant species. 18 (a) Floodplain I I Confining Unit / r Fig. 7: From Hardison et al. (2009), demonstrating the differences in channel form that can lead to Riparian Hydrologic Drought, the wilting of short -rooted riparian vascular plants as incision lowers the local water table and deprives floodplains of periodic inundation during high flow events. Comparative analyses conducted in the Appalachians and across the Carolinas indicate that beaver ponded streams are better for bat forage (Franc) et al. 2004) and nesting (Menzel et al. 2001), better for avian communities (Otis & Edwards1999), better at reducing suspended sediment and nitrate loads (Bason et al. 2017), better for the richness, diversity, and evenness of herpetofaunal communities (Metts et al. 2001) than other streams, wetlands, or forests depending on the study in question. Of particular interest to regulators concerned about minimizing impacts to the `use' of streams and wetland in favor of beaver ponds, you might read the concluding paragraphs of one essay, the heading of which is entitled, "Beavers do not present a threat to flowing -water species and need not be controlled for that reason" (Snodgrass 1997, pg. 1055). Snodgrass suggests that land managers should only consider beaver removal when land management objectives favor valuable timber stands and the preservation of access roads. The client and design team are aware of this management issue and are developing the buildings and roads with potential flood extends and wetland expansion in mind. I% 4. DESIGN "We cannot know what we are doing until we know what nature would be doing if we were doing nothing." Our restoration work is guided by the above refrain, written in 1979 by the farmer -poet, Wendell Berry. In all of our work, we strive to emulate and catalyze the natural processes of self -renewing ecosystems. Our experience continues to strengthen our devotion to natural process -based restoration as the only sustainable way to manage aquatic resources. 4.1 Design Approach Scholarship and responsible practice demand that river restoration be based on or include five principles (Kondolf and Larson 1995; Hughes et al. 2001; Kondolf et al. 2001; Ward et al. 2001; Hilderbrand et al. 2005; Wohl et al. 2005; Kondolf et al. 2006; Sear et al. 2008; Brierley and Fryirs 2009; Hester and Gooseff 2010). These principles — and how we've endeavored to implement them — can be summarized as follows: 4.1.1 Restoration Principals First, restoration should be designed with explicit recognition of complexity and uncertainty regarding river process and form, including the historical context of variations in process and form through time. We have observed Hopewell Branch and Thomas Branch through this lens, using Cluer & Thorne's (2014) Stream Evolution Model (SEM) to conceptualize not only the present dominant processes at work, but those trajectories that may apply under expected future scenarios and the legacies of the past that compromise habitat on site today. Second, restoration should emphasize processes that create and sustain river processes, rather than imposition of rigid forms that are unlikely to be sustainable under future water and sediment regimes. On Hopewell Branch and Thomas Branch, we are recommending wetland complex systems created by small BDA structures that enable the system to undergo the transformation it would eventually undergo if we did nothing. Further, our intention is not to build permanent structures or "freeze" the stream in time 1 year after construction. Rather, we are proposing wetland complex systems that will be stable in the near -term while catalyzing processes that offer a path to self -adjustment and ongoing improvement despite changes to the watershed. This is an important consideration for our restoration approach as the planned development in the Thomas Branch watershed would otherwise cause degradation, and the development pattern in the Hopewell Branch watershed is uncontrolled and unpredictable. To expect incoming flows to follow the same trends present in our recent observations (2019-2020), would be folly. Our approach is to design a channel and a NE floodplain that anticipate future geomorphic trends and have the capacity to adapt and thrive in spite of potential future impacts. Third, projects should be monitored after completion, using the set of variables most effective for evaluating achievement of objectives, and at the correct scale of measurement (Comiti et al. 2009 provides an example of effective monitoring). The proposed restoration efforts at Mulberry Gap are not tied to any mitigation performance standards. However, the operations at the proposed SoWE campus will include long-term operation and maintenance of the grounds, including these wetland complex systems. There will also be on -site stream and weather gages so that the maintenance plans and adaptive management can be tied to specific triggers (i.e. storm flood events). Fourth, consideration of the watershed context, rather than an isolated segment of river, is crucial because of the influences of physical, chemical, and biological connectivity on alterations undertaken for river restoration. Our approach aims to leverage the full project area of floodplain and stream corridor within the context of the high gradient watershed that feeds it. Moreover, by working within the floodplain area, we will create habitat diversity that can sustain a more biodiverse community of native flora and fauna adapted to floodplain conditions long absent from this site. Fifth, accommodation of the heterogeneity and spatial and temporal variations inherent in rivers is necessary for successful restoration (Brierley and Fryirs 2009). The proposed wetland complex systems on Hopewell Branch and Thomas Branch will continue to adjust parameters such as bedform configuration, grain -size distribution, and emergent vegetation clustering in response to fluctuations in water, sediment, and wood yields. These adjustments are commonly not synchronous or of the same magnitude between distinct reaches of the river. So, our design will allow the BDA features some freedom to adjust, and this will be reflected in the long-term operation and maintenance plan. 4.1.2 Restoration Techniques FIDE considered two approaches to water resource conservation and restoration enhancement during the design phase: Natural Channel Design and Process -Based Design. The former approach was screened from consideration because it fails to achieve a high level of habitat conservation and enhancement, a consideration of utmost importance for the client (SoWE). Natural Channel Design, as described in the Engineering Handbook on stream restoration, is at its heart a misnomer. Former channels are abandoned for excavated channels in the floodplain. Beds and banks are rigidly held in place by robust quantities of rock not native to the local lithology. This approach creates an artificial and contorted canal masquerading as a `natural feature'. On the other hand, Process Based Design catalyzes self -renewing cycles of stream/floodplain/wetland interactions to create habitat that is responsive to the natural forces at work on the site. We trust natural processes will dictate the expansion of wetland areas and delineation of streams. We have provided a broadly applicable illustration that 21 shows these potential outcomes in the appendix (see the "Potential Outcomes after BDA Construction" illustration). And the client is willing to accommodate increased lateral and vertical connectivity over strictly defined and rigidly maintained canal and wetland boundaries. RIDE and the State of North Carolina have a unique opportunity on this site to follow the lead of many other states in the US currently engaged in encouraging beaver mimicry and hopeful beaver reintroduction. In the arid western United States, Process -Based Restoration approaches including beaver dam analogs, post -assisted log structures, large woody debris jams, and rewilding of beaver have made demonstrable improvements to fish populations, riparian corridor width and vegetation densities, water quality parameters such as temperature, turbidity, and nutrient concentrations, and fire suppression in every case we know of. While in the west, primary habitat loss has occurred from a legacy of overgrazing and water diversion, here in the southeast, legacy effects of soil loss and `positive drainage improvements' have had similar consequence to aquatic habitat and the native plant communities that depend on soggy soils and periodic flooding for the nutrients, seed dispersal, and open space to achieve population dynamics that work with, rather than against, the coevolution of wetland communities and ecosystem engineers, like the beaver that once had a hand in every trickle of WoUS, an indelible and forgotten influence on the landscape. 4.2 BDA Type Selection We considered three design alternatives for the BDA structures, these typologies are as follows: 1) Post & Weave BDA: Posts driven into the channel and floodplain at regular intervals with long small caliper trees and branches woven into the structure. Mud, gravel, and stone is packed against this hand -built structure. These structures are intended to provide habitat that attract beavers. This would not be a permanent feature; it would require regular maintenance and would likely need to be re -built in the event of an extreme storm event. 2) Full Engineered with Facade: Building on the option above, but with extensive grading and structural subsurface elements (sheet piles, concrete cores, etc.). These structural elements would physically impound the water, provide a non -erodible barrier, and prevent seepage. This also requires regular maintenance but is less susceptible to failure and is less adaptable to changes in regimes of flow, sediment, and wood. This option has been disregarded because of its reliance on non -natural materials and susceptibility to weaken over time and its susceptibility to failure with changing conditions. This alternative offers a robust, but not resilient approach. 3) Aaaradation Structure: In this third option — which we are proposing at SoWE — engineered materials (stone aggregates, woody materials, and fine grained soils) provide the `core' of a retention structure upon which additional mud and sticks are placed to replicate a beaver dam. Post and weave BDA is then built on top of this 22 earthen feature. This would require regular maintenance, but less maintenance than the post & weave option alone, and would be more robust in the face of extreme storm events. This third option (aggradation structure) is contextually appropriate and balances the benefits and drawbacks of all the three options. The core of these BDA features will be constructed of carefully blended aggregates for site -specific incipient motion criteria. The aggregate will include a wide range of grain sizes, ideally native material consisting of cobble, gravel, sand, and silt, and will be placed in layers of gradually increasing grain size. When this inner core of the BDA aggradation structure is built, it will appear to be a natural riffle. After the core has been constructed, the BDA feature will be capped with interlocked woody material. A slash matrix will be fanned -out on the downstream side of the feature, in the dip of the ogee shape, and imported cobble will be used as a downstream armor layer that anchors the woody material and resists scouring to a higher degree than the core aggregates. The size of this cobble will be in the uppermost range of the largest cobble native in the system. The larger cobble will then be covered with a thin layer of the native bed material, providing a soil matrix for emergent vegetation. The shape of these BDA features will be convex in plan -view, pointing in the downstream direction. In profile, they will have a 2H:1 V or milder grade on the upstream side with a designed ogee shape on the downstream side. The downstream side will also consist of the largest gradation sediments, carefully designed, but likely cobble -sized material and interwoven with woody material. 4.3 Proposed Features Our approach includes hydraulic and geomorphic design considerations. This approach ensures that the individual BDA features are dimensioned to sufficiently resist the stresses and velocities they will have a 2H:1 V or milder grade on the upstream side with a designed ogee shape on the downstream side. The downstream side will also consist of the largest gradation sediments, carefully designed, but likely cobble -sized material and interwoven with experience during regular floods, while allowing certain areas to break- away during extreme, catastrophic events (i.e. 100-year recurrence storm). 4.3.1 Beaver Pool Design The future marsh aprons upstream of the BDAs will be selectively excavated to provide undulations and deep -water refuge. A variety of depths and morphologies will provide habitat and thermal heterogeneity. Longitudinal profiles of Thomas Branch and Hopewell Branch, have been provided in the appendix, and the appendix also includes an example cross section cut through the floodplain of the core area along Thomas Branch — this section shows the topographic heterogeneity proposed in the floodplain. 23 These micro -topographic features can be seen on the grading plans and the Predicted Depth Maps (see appendix). The complicated relationship between seepage, evapotranspiration, and the potential inundation extent is difficult to predict, but the vegetation plan will feature plants with population dynamics having the capacity to adapt to these future water level conditions. We have prepared depth maps that predict and define the areas upstream of each BDA feature into their respective depth zones. These zones were developed using the range of probable conditions, from flooded conditions to drought conditions. A flooded condition was defined as V above weir crest elevation and drought was defined as 2' below weir crest elevation. These zones are defined here: ■ Deep pool zone: sustained deep pools (3' or greater). This zone represents areas that retain 3' depths during drought conditions. 3' was chosen for this delimiter because this is the minimum depth for beaver shelter and this will stifle growth of emergent wetland plants keeping vigorous vegetation growth along the fringe areas. ■ Deep Marsh / Submergent Zone: typically inundated (2' - 6). Submerged plants are expected here. ■ Shallow Marsh / Emergent Zone: frequently inundated (0' - 2'). This zone would not be inundated during drought conditions, but would be inundated to some level depending on other environmental conditions. The upper bound of this zone is defined by the crest elevation of the floodplain BDA. Emergent plants will be appropriate, but this zone is the hardest to predict. ■ Lower Riparian Zone: infrequently inundated. This zone would be inundated only when the water level goes above the weir/floodplain BDA, which would happen infrequently. This zone will have shallow groundwater and contain very moist soils. ■ Upper Riparian / Upland Zone: not typically inundated. This zone will also have shallow groundwater, but is not expected to be inundated. The BDA features and our predicted depth maps will be initially planted based on these expected conditions, but ultimately, these features are meant to change and to adjust based on their temporally varied inputs of water, sediment, and wood. 4.3.2 TB4 All the BDA features will be constructed within the existing channel-floodplain topography, with some excavation in opportune areas for habitat diversity (described above in the beaver pool design section). It is likely that all the pools will have seasonal and storm - related fluctuations in pool elevation. We know that the pool elevations won't stabilize any higher than the in -channel BDA crest elevation, but we cannot predict exactly how low the pool elevation will be when it reaches equilibrium. This uncertainty is because of the complicated dynamics between inflows (rainfall and groundwater) and outflows (seepage and evapotranspiration). We cannot predict what the equilibrium pool elevation will be at a particular BDA, although we know reducing the outflow parameters will have an increasing effect on pool elevation. 24 The proposed pool upstream of Thomas Branch BDA #4 (aka TB4) is the largest and most prominently featured on site. Because of this reason, we were tasked with developing a nature -based approach to hedge against the outflow variables. This makes the pool design upstream of TB4 a deviation all other proposed BDAs. The floodplain area above TB4 will be excavated and then amended with clay soil to reduce permeability in the deep pool areas (see engineering plans, sheet C102). The existing channels and the fringe areas (shallow marsh and lower riparian zones) will not be amended with clay soil to allow for hyporheic exchange. 4.3.3 Additional Woody Structures Other low -tech, process -based restoration strategies will be incorporated at other areas on site, or as an adaptive management strategy through long term operation and maintenance. For example, downstream of the proposed administration building on Thomas Branch — where the valley necks -down to a more confined floodplain — BDA weir -like features are infeasible here. However, it is appropriate to install a permeable large woody debris structure (see example detail in the Engineering Plans). This would allow base -flow to pass through unencumbered but would provide a backwater affect on its upstream BDA counterpart during storm events, reducing storm event stresses and create a fluvial transition zone between the BDAs and the downstream single -thread channel. This approach would decrease erosive forces in -stream and increase resident times for wood, organic material, and sediment — contributing to the overall goal of the wetland complex system. 4.3.4 Flow Diversion Devices So-called "pond levelers" or "beaver deceivers" — or more sophisticated Agridrain systems — are a common tool used to manage nuisance water levels of beaver impoundments. These devices can be incorporated on the peripheral of beaver -made dams or human -made BDA's to avoid unwanted flooding, but they must be carefully designed so that they are not immediately clogged by the eager beaver. These devices are commonly installed at existing roadway culverts, and generally these devices fall within the non -notifying category of activities in Waters of the US. We have incorporated a flow diversion device into this plan, but the purpose is NOT so that the pools maintain a minimum elevation. Instead, this device is anticipating potential flooding problems. As initially designed, the stream -wetland complex will not inundate roads or walking paths. However, in the event that natural processes cause flooding, this flow diversion device will already be installed to allow for vehicular and pedestrian ingress/egress around the complex. Natural processes that could cause this type of flooding include beaver activity that increases the elevation of the BDAs, or sediment and wood recruitment from large storm events. An Agridrain device will be embedded into the BDA weir, but separated from the main BDA spillway area. The intake areas for this Agridrain device will be caped with "T" connection and screened to dissuade from clogging. This intake will be placed in a deep 25 pool and the outlet will be buried and in the downstream floodplain and released in the downstream channel. The need for additional flow diversion devices is not anticipated at this time. 4.3.5 BDA Degradation Analysis Wild beaver dams are in a constant state of degradation, constantly being rebuilt by the beaver colony. Hence the "business" that is often used to characterize this keystone species. These BDA structures are designed to mimic their natural counterparts, and in keeping with this approach, the BDA weirs have been specified to naturally degrade during large storm events. We have performed hydrology and hydraulic calculations for each of the proposed BDA weirs. Through this analysis we have estimated the shear stress that BDA will experienced during predictable rain events. Based on this analysis, we have sized the materials to become mobilized during large storms. Particularly, the stone gradation of the in -channel BDA has been specified such that large storm events will exceed the incipient motion criteria. That is to say: the dams are designed to partially degrade during large storm events. 4.3.6 Erosion Control The in -channel BDA features will be constructed "in the dry." A temporary coffer dam (see appendix) will be placed on the upstream toe of the proposed BDA feature and a small trash pump or other similar method will be used to divert water around the work area. All work will be planned such that the coffer dam will not become overwhelmed during storm events and the individual work areas will be stabilized at the end of each day. There are several being removed and converted back to open channels. Upon removal of these culverts the channels will be re -constructed in accordance with the culvert removal details (see appendix). Culvert removal and channel construction will be conducted "in the dry" using similar methods used to dewater the BDA work areas (coffer dam and pump around). 4.3.7 Vegetation Native riparian plant species have evolved to withstand and depend on the natural flow regimes and disturbance regimes that trigger seed dispersal, cavitation, and propagule establishment in stream corridors and adjacent floodplains, so that extreme deviations due to anthropogenic disruption could incur cascading habitat impacts (Tyree et al. 1994; Schaff et al. 2003; Merritt et al. 2010; Osterkamp & Hupp 2010; Wohl 2019). Thus, spatial and temporal dynamics of connectivity are important factors driving the form and function of streams as ecological agents of the landscape. Although beaver reintroduction is not planned, and is not a specific goal of these efforts, the vegetation plans are being prepared in -keeping with beaver habitat. 26 Most of a beaver's diet is made up of tree bark and cambium. Cambium is the soft tissue that grows under the bark of a tree. Willow, maple, birch, aspen, cottonwood, beech, poplar, and alder trees are preferred varieties, but beaver are known to eat other vegetation like roots and buds and other water plants. All plantings around the BDA complex will be native species adapted to the hydrologic conditions we intend to restore on site. A list of desirable native vegetation that will be incorporated is included in the Operation and Maintenance Manual. Riparian, wetland, and emergent planting plans are being prepared by Osgood Landscape Architecture. A selection of plants that are under consideration for both the initial planting plan, and the long-term adaptive management of these areas are included below. 27 Riparian Zones Trees o Red Maple - Acer rubrum o Swamp White Oak - Quercus bicolor o Smooth Serviceberry - Amelanchier laevis o American Elderberry - Sambucus canadensis o Black Gum - Nyssa sylvatica o Bitternut Hickory - Carya cordiformis o Fringetree - Chionanthus virginicus o Sourwood - Oxydendrum arboreum o Ironwood - Carpinus caroliniana o River Birch - Betula nigra o American Holly - Ilex opaca (spec it in drier areas within the riparian zone) o Sycamore - Platanus occidentalis o PawPaw - Asimina triloba o Black Willow - Salix nigra (spec it in wetter areas within the riparian zone) Shrubs o Winterberry - Ilex verticillata o Possumhaw - Ilex decidua o Silky Dogwood - Cornus amomum (this spreads to form thickets - use sparingly in the planted area around the managed main pond and more of it in the other less managed riparian areas) o Spicebush - Lindera benzoin o Sweetspire - Itea virginica o Buttonbush - Cephalanthus occidentalis (spec it in wetter areas within the riparian zone) o Sweet pepperbush - Clethra acuminata (spec it in wetter areas within the riparian zone) o Witch hazel - Hamamelis virginiana o Doghobble - Luecothoe fontanesiana o Possumhaw Viburnum - Viburnum nudum o Silky willow - Salix sericea (spec it in wetter areas within the riparian zone) Herbaceous / Grasses o Fox sedge - Carex vulpinoidea o Blunt broom sedge - Carex scoparia (spec it in wetter areas within the riparian zone) o Tussock sedge - Carex stricta (spec it in wetter areas within the riparian zone) o Pink Turtlehead - Chelone lyonii o Golden Groundsel - Packera obovata o Mountain Mint - Pycnanthemum virginianum 28 o Milkweed - Asclepias incarnata o Grass leaved Goldenrod - Solidago graminifolia o Sensitive Fern - Onoclea sensibilis o Cinnamon Fern - Osmunda cinnamomeum (spec it in wetter areas within the riparian zone) o Joe Pye Weed - Eupatorium purpureum o Switchgrass - Panicum virgatum (this is a fast spreader - consider specing it sparingly in the planted area around the managed main pond area and more of it in the other less managed riparian areas) o River oats - Chasmanthium latifolium (this is a fast spreader - consider specing it sparingly (or not at all) in the planted area around the managed main pond area and more of it in the other less managed riparian areas) o Indian Grass - Sorghastrum nutans o Cardinal Flower - Lobelia cardinalis (spec it in wetter areas within the riparian zone) o New England aster - Aster novae-angliae o Jack in the Pulpit - Arisaema triphyllum (spec it in wetter areas within the riparian zone) Emergent Zones Herbaceous / Grasses o Soft Stem bulrush - Scirpus validus o Common Rush - Juncus effusus o Blunt Spike Rush - Eleocharis obtusa o Pickerelweed - Pontederia cordata (this is a fast spreader - consider spacing it sparingly (or not at all) in the planted area around the managed main pond area and more of it in the other more wild riparian areas. If this plant is both hearty and spreads quickly, it may be best used in areas where the expected water level is the most unpredictable.) o Southern Blue Flag - Iris virginica o Sweetf lag - Acorus calamus (straight species) o Lizard's Tail - Saururus cernus this is a fast spreader - consider spacing it sparingly (or not at all) in the planted area around the managed main pond area and more of it in the other less managed riparian areas. Maybe use this one and Pickerelweed as more "wild" solutions. o Arrow Arrum - Peltandra virginica o Duck Potato - Sagittaria fasciculata 29 REFERENCES Ayres, Q. (1936). Soil Erosion and its Control.

INTRODUCTION The applicant, Mulberry Farm Madison LLC represented b� erRichard a Section, 04 Individual Permit and 401 Individual Water Quality tification Kelly, is seeking 2,062 0.161 GeFto fineatien AQA for 416 linear feet (0.0807 acres) of impact to 0.022 streams and 8.044 acres of impacts to wetlands, and Natie^wide on Thomas Branch and Hopewell Branch and unnamed tributaries. The impacts are associated with the construction of a residential education and training center called the School for Wholeness and Enlightenment (SOWS). The project site consists of +/- 448 acres located at 1126 Upper Thomas Branch Road, Marshall, North Carolina. The applicant is submitting this O&M plan to satisfy the monitoring plan requirement feF,--ra m as a proposed permit condition. This document describes a monitoring and management regime that will require dedicated professionals to implement, but is applicable across the SOWS campus and is adaptable over time. This document replaces the previous monitoring plan submittal. The BDA stream -wetland complex systems will be monitored and evaluated based on the following quantifiable elements: - Rainfall accumulation - Surface water levels - Ground water levels - Water temperature and other physiochemical components - Dynamic fluvial traits - Vegetation species and density These elements will be evaluated, over time, to understand the trajectory of the system and adaptive management strategies will be implemented on a case -by -case basis depending on the system's trajectory. The ecological functioning of the stream -wetland complex and associated vegetation will make the SOWE campus beautiful and inspiring. BDm wo ri riuia ii acIIVVI vi VVIIVIWIIWaa u11u o1u1yi1LWL 2. OBJECTIVES This manual offers practical guidance on the monitoring, maintenance, and adaptive management operations of the BDAs and associated wetland complex and vegetation at SOWS. These guidelines should serve SOWE staff in their efforts to maintain the health, function, and appearance of these areas. The design of these features has been carefully considered to augment ecosystem services that improve water quality, restore habitat, and enhance the visitor experience at SOWE. The key components contributing to these improvements are the BDA structures and the vegetation. As such, the purpose of this manual is to outline key considerations for maintaining the function and integrity of the BDAs and these important plant communities which will, in turn, support the health of the stream -wetland complex on the SOWE campus. The Monitoring and Management Objectives are listed below. • Support water quality improvement. • Provide forage and shelter for pollinators, aquatic invertebrates, and birds. • Provide beautiful and inspiring scenery (this objective will not compromise the preceding objectives) 2.1 Support Water Quality Improvement The American Beaver ( Castor canadensis) were once common in stream systems across the United States and played an important ecological role. Beaver dams impound stream and river systems, creating wetlands that raise the ground water table and allow the adjacent wetlands to act as a sponge - absorbing flood waters and slowly releasing ground water - creating a more resilient system. This project uses beaver dam analogues (BDAs), which are structures designed to create similar hydrologic impacts as natural beaver dams. The existing streams proposed for restoration utilizing BDA features are poor quality ecosystems, with degraded channel and riparian functions. This manifests as homogenous stream bed structures, poorly established or absent woody plant buffer, and underutilized capacity for floodwater retention and attenuation. We expect the introduction of these BDA features to reduce slope gradient thereby reducing sediment transport capacity, diversifying bed sediments, and increasing ground water recharge. Enhanced flood storage capacity will be achieved by creating a highly accessible BDA O&M Plan // School of Wholeness and Enlightenment // Page 6 and topographically diverse floodplain, resulting in flattening and elongation of storm hydrographs. Through these fluvial processes, BDA features will create a heterogenous stream -wetland complex. Fluctuating surface water and groundwater levels within the wetland complex will promote nutrient transformation and assimilation, consequently improving freshwater habitat conditions in the project area. The native trees, shrubs, grasses, and herbaceous perennials planted around this wetland complex also contribute to water quality improvement in several ways. vegetation decreases erosion by adding "roughness" that slows water velocity, and holding soil in place with deep, networked root systems. Additionally, many types of pollutants are taken up and absorbed by plants, reducing their occurrence in waterways. 2.2 Provide forage and shelter for wildlife Beaver dam -formed wetlands provide habitat for many species of birds, mammals, amphibians, and insects. Microtopography around the BDA structures will support a range of emergent species in shallow water areas and riparian species along the banks and on small hummocks that are crucial for bird nesting. The assemblage of plants selected for the BDA wetland complex provide an array of forage, blooming at different times of the year and serving different life stages of pollinator insect species. The shelter that these plants will offer comes in the form of hollow stemmed grasses perfect for encasing larval pollinators and dense undergrowth offering protection for ground nesting birds. In an experiment observing ecological productivity of agricultural hedgerows in the Mid -Atlantic region of the United States, researchers found that hedgerows consisting of non-native plants had 90% fewer caterpillars than their ecologically productive native plant counterparts (Richard et al. 2018). Given that most bird species are insectivorous at birth, one can imagine how the presence or absence of flourishing invertebrate communities impacts the availability of suitable nursery environments for avian life.

The diagram above demonstrates the comparative ecological productivity (as measured by species interactions) of diverse native landscapes as compared to monocultures of close - cropped grasses. (Image: Sturm & Frischie (2020)) 2.3 Provide beautiful and inspiring scenery We have evolved to appreciate the gestalt presented by a well - functioning ecosystem. gestalt.- an organized whole that is perceived as more than the sum of its parts. On the whole, it is the ecological functioning of the stream -wetland complex and associated vegetation that will make these stream - wetland complex systems beautiful and inspiring. However, some aesthetic components of the site maintenance will neither diminish nor enhance the ecological functions discussed above. For example, pruning trees for pedestrian safety and appearance in addition to health, choosing plants that have more charismatic flowers even if the pollinator benefits are the same, and planting in legible species clusters so that the eye can register patterns even though pollinators show no preference. Maintenance for aesthetic design will never take priority over ecological function, but it will enhance the visitor experience at SOWE. Joan Nassauer's essay, Messy Ecosystems, Orderly Frames offers some strategies that can be employed at SOWE to show what she terms "cues to care" in the landscape. Two example cues to care that could help people appreciate landscape at SOWS are: • Maintaining neat edges by mowing a narrow strip between the edge of the riparian vegetation zones and pedestrian paths. BDA O&M Plan // School of Wholeness and Enlightenment // Page 8 Incorporating suitable native plants with large, showy flowers or foliage instead of using only plants with clusters of small flowers. Plants with diminutive flows are often perceived as weedy, and it is often easy to find showier native plants that fill the same ecological niche. 3. MONITORING It will be essential to monitor this novel ecosystem before establishment and through development for management and maintenance decisions. While regulatory requirements for BDA style restoration are not currently codified, we are proposing a rigorous monitoring regime to ensure onsite and downstream water quality protections. This monitoring is recommended to document the ongoing success of this milestone ecological restoration project and to ensure that the project is meeting intended goals. 3.1 BDA Weir Inspections If a beaver colony existed at this site, the BDA features would be in a constant state of structural maintenance. Beavers would be stacking stones, pressing mud, and weaving branches to ensure that the pools sustained depths sufficient for refuge. However, beavers are not expected to inhabit these features in the near future. Therefore: The pools and the entire linear length of the BDA weir will be visually inspected after every storm event which exceeds 1.5 inches in 24 hours. Overflow areas along the BDA weir will be noted and inspected for erosion after the water level drops. Reporting for these efforts will include field reports and photographs. 3.2 Hydrologic Monitoring Hydrologic monitoring will include continuous monitoring of rainfall, barometric pressure, and air temperature. Hydrologic monitoring will be evaluated to inform the SOWE's decisions for adapting the riparian, wetland, and open water areas towards the design goals. BDA O&M Plan // School of Wholeness and Enlightenment // Page 9 3.3 Hydraulic Monitoring Groundwater monitoring wells and surface water monitoring gages will be recorded continuously. These will be installed to evaluate fluctuations and direction of flow between the BDA pools and the adjacent uplands. Groundwater levels will be evaluated to inform SOWE's decisions for adapting the riparian areas. Reporting for these gages will be a sub -hour time series that show relative elevations and accurately depict storm event hydrographs. 3.4 Alignment and Texture Mapping Annual aerial photographs will document the fluctuation in water flow paths through repeated inundation and drying cycles. The use of a drone aircraft will assist in documenting the aerial view of the site under varying hydrologic conditions. Alternatively, publicly available aerial imagery can be utilized to document changes over time. Reporting for these efforts will be annual maps that show changes in the channel alignment and clearly depict areas with an anabranched pattern. Annual texture mapping will be conducted to quantify roughness characteristics in the channel and floodplain. Texture Mapping that incorporates and quantifies all roughness features (e.g. vegetation, bedforms, grain roughness, etc.) will be accomplished discretizing areas by type and then quantifying the roughness of each feature. For example, gravel bars will be measured using the Wolman Pebble Count, and bedforms such as sand dunes will be measured directly. Reporting for these efforts will be annual polygon -based GIS maps that show changes in surface texture. 3.5 Sediment Mapping Annual longitudinal profile surveys will be performed across each in - channel BDA to evaluate scour, deposition, and crest elevations. Annual cross section surveys will be performed along select pools, upstream of BDA structures. The cross -sections will be monumented with permanent capped rebar pins on each bank to serve as a spatially referenced control. The cross-section surveys will be repeated annually using a laser -level, reel tape, and stadia BDA O&M Plan // School of Wholeness and Enlightenment // Page 10 rod. Photographs of each cross section facing upstream and downstream will be taken on the day of monitoring. The location of these control pins will be recorded with a sub -meter accuracy Global Positioning System (GPS) device. Stream surveys will follow the methodology contained in the USDA forest service manual "Stream Channel Reference Sites" (Harrelson, et al 1994). Reporting for these efforts will be to quantify sediment accumulation / erosion and observe long-term trends in aggradation or degradation of the system. 3.6 Wood Monitoring Annual mapping of large woody debris, snags, and rack -lines will be performed. Appropriate methods for these efforts include WOODDAM and LWDI. Reporting for these efforts will include an annual GIS map showing large debris and snags, along with the reports from the selected wood quantification method. 3.7 Physiochemical Monitoring Water temperature will be collected continuously and evaluated twice per year. Temperature measurements can be recorded continuously using HOBO "Pendant" MX Water Temperature Data Loggers. Other physicochemical samples will be collected annually. This monitoring will consist of turbidity, conductivity, pH, dissolved oxygen, and dissolved nutrients. Physicochemical monitoring stations will be established at the outlet of each BDA complex. Samples will be sent to PACE Analytical Laboratory for analysis. Baseline samples will be collected before creation of the BDA features. This information, along with state standards, will be used to evaluate the physiochemical affects that the BDA stream - wetland complex imposes on the receiving waters. Reporting for these efforts will be an annual report that quantifies temperature and other physiochemical affects to downstream waterways. 3.8 vegetation Monitoring BDA O&M Plan // School of Wholeness and Enlightenment // Page 11 Vegetation monitoring will consist of plots along transects spanning from the deep pool to the upper edge of the upper riparian zone. The vegetation plots will utilize methods established by the Carolina Vegetation Survey-EEP Level 3 Protocol (Lee et al., 2008). Level 3 plots document the overall abundance and of leaf area cover of the more common species in a plot. Cover is estimated for all plant species exceeding a specified lower level (typically 5% cover); species present but with cover lower than the cut-off may be ignored. In these plots, natural and planted woody stems are recorded by size class and vigor. These plots allow an accurate and rapid assessment of the overall trajectory of woody -plant restoration and regeneration on a site. The information collected meets the Ecological Society of America (ESA) guidelines and Federal Geographic Data Committee (FGDC) standards for plots used to classify vegetation to an association within the U.S. National Vegetation Classification (NVC). Plots shall be established as shown in the appendix. Assessments will begin being conducted after construction. 3.9 Invasive Species Monitoring Seven invasive species have been identified for monitoring and targeted control, and the appendix of this manual helps with identification of these species. Care should be taken to note the presence of these species in the vegetation plots and calculate the percent invasive cover for each plot. This list is not exhaustive, but it should serve as a small, targeted list highlighting the most immediate threats of colonization by exotic invasives while the focal plant species populations establish. The seven target invasive species (described further in the appendix) include: • Royal paulownia (Pau/ownia tomentosa) • Asian bittersweet (Celastrus orbiculata) • Chinese Privet (Ligustrum sinense) • M u I t i f I o r a rose (Rosa multiflora) • ,Japanese barberry (Berberis thunbergii) • Autumn olive (Elaeagnus umbellata) • Goat willow (Salix caprea) In addition to the above, these species are a serious problem in the North Carolina mountains region and should be monitored: • Tree of Heaven (Ailanthus altissima) • ,Japanese Meadowsweet (Spiraea japonica) • ,Japanese Knotweed (Polygonum cuspidatum) • Chinese Yam (Dioscorea polystachya) • Chinese Silvergrass (Miscanthus sinensis) • Coltsfoot (Tussilago farafara) • Japanese stiltgrass (Microstegium vimineum) • Garlic Mustard (Aillaria petiolatq) • Mimosa (Albizia julibrissin) 4. ADAPTIVE MANAGEMENT In general, this management regime has the goal of maintaining or improving post -construction site conditions over baseline conditions, thereby restoring or enhancing the ecosystem. The following sections outline adaptive strategies that aim to maintain or enhance the physical, chemical, and biological integrity of surface waters, both on -site and off -site (downstream). 4.1 BDA Weirs Erosion and degradation of the BDA weirs is expected. If the in - channel portions of the BDA are found to be eroded, or "shortened," they will be refreshed by hand in accordance with engineering plans using similar materials (e.g. stone grain size) to rebuild the feature. No large equipment (e.g. track hoes or mini excavators) shall be used below the ordinary high water mark. If the in-floodplain portions of the BDA weir are found to be eroded or degraded, they can be rebuilt in accordance with the engineering plans using similar materials. Live stakes or other hardy vegetation will aid in "roughening" and "reinforcing" areas that tend to degrade. No large equipment (e.g. track hoes or mini excavators) shall be used below the ordinary high water mark. 4.2 Vegetation Performance Groundwater and surface water will be evaluated alongside performance of vegetation. SOWE will assess the need to adjust the planting plan and propagate species upslope or downslope based on the data. 4.3 Temperature Performance Temperature impacts are not expected to create any deleterious effects downstream. However, if temperature spikes are observed, shade -provisioning vegetation can be installed in areas that are accepting solar radiation.

I have listed these comments here and responded to each. 1 - There is not a clear difference between pool habitat and deep marsh, as described. Pool habitat would be >=3 ft in depth and deep marsh would be 2-5 ft in depth. These definitions overlap. The difference between Deep Pool and Deep Marsh/Submergent Zone is that under expected typical conditions, the Deep Pool Zone will be 5-7' deep while the Deep Marsh/Submergent Zone will be 2-5' deep. The description of the Deep Pool as >= 3' deep means that we expect the depth to be as low as 3' in depth during drought conditions. For the Deep Pool/ Submergent Zone, the drought condition would be 0' in depth. Drought condition was defined as 2' below typical level. 2 - What is the maximum depth of the deep pool zone? The maximum depth during expected typical conditions would be 7'. However, during storm conditions, which we defined as 1' above typical water level, the depth could be as much as 8'. There are only very small areas that would actually be this deep. Typical depths in the Deep Pool Zone for TB2 and TB3a&b are designed to be only 5-6' (as opposed to 5-7' for TB4a&b), and TBSa&b do not have a Deep Pool Zone. 3 - The plant list needs to be Modified: 3a - Deep Marsh is also defined as supporting submergent plants. Given the range of depths for this zone, we are wondering what native plants would thrive here. The 129 31d Avenue West, Hendersonville, NC 28792 11 robinsondesignengineers.com Dist provided on plan sheet L-2.00 for that zone is a list of species that would survive in standing water for a long period but in inches, not feet of water. We have changed the planting lists (see C805 in engineering plans) so that we will no longer be planting in the Deep Marsh/ Submergent Zone because we had the same concern when reviewing our plans. Some aquatic plants such as Nympheo odorotowould thrive in this zone, but on the advice of our peer reviewer Kevin Caldwell, we decided against including these. Kevin reasoned that these might take over the area and deplete oxygen levels, and that they will likely be brought in by waterfowl over time anyway. The newly created Zone D (BDA Zone) on Sheet C805 is not to be confused with the old Zone D (Deep Marsh/submergent Zone). This zone is specific to the BDA structure. 3b - Shallow marsh is defined as 0-2 ft in depth and supporting submergent plants. Again there are problems with the plant list provided on L-2.00. These plants cannot survive if inundated for more than several days. It's a nice list, but it would do best on the fringes of the area that would see inundation. We have adapted the list of plants that would be in the Shallow Marsh / Emergent Zone (see Sheet C805). The plant lists now includes more plants that can tolerate growing in shallow water, and that fit into the plant communities that reviewer Kevin Caldwell advised. We understand that the ability of these plants to grow in the deeper areas of this zone is questionable. For this reason, we will do a phased planting for this zone (Zone C - Shallow Marsh/Emergent Zone). The upper bound of the zone will be planted along with the other zones, but the lower bound will be planted at a later date only if the water levels are lower than expected. 3c - There are no aquatic plants included (although Nymphea odorata is included as an alternate on L-2.00). Given the depths expected, this suite of plants should be included in the planting list. Aquatic plants such as Nympheo odoratowould thrive in one of two zones, but on the advice of our peer reviewer Kevin Caldwell, we decided against including these. Kevin reasoned that aquatic plants might take over the area and deplete oxygen levels, and that they will likely be brought in by waterfowl over time anyway. 3d - L-2.00 has a note that "alternative and similar native plant species" may be used. We recommend that this plant list be hammered out with review by agencies. If substitutions are needed after the fact, they should be vetted with agencies. Our updated plant lists will not include this note allowing unchecked substitutions. Necessary substitutions will be properly vetted and they will abide by the plant list of appropriate species by plant community provided by Kevin Caldwell. 4 - Given the depths of water that are proposed, we are concerned about the risk of invasion of non-native invasive plants and animals in the BDA impoundments. These may come in with nursery stock (which is common when planting aquatic plants sourced from nurseries that have issues with non-native invasives, such as exotic snails, mosquito fish, etc.) or in other ways. The maintenance/monitoring plan should include surveys for and removal of non -natives. 20310.Memo.211103.docx 2 of 3 Now that we have largely excluded aquatic plants from the planting list, we expect this to be less of an issue. However, the Operations and Maintenance will be updated to include surveys for and removal of non-native aquatic animals in addition to the attention to non-native plants. 4 - We recommend including some sort of time -frame for the vegetation monitoring. We are changing the vegetation monitoring section of the Operations and Maintenance Manual to reflect Kevin Caldwell's comments. Rather than CVS plots as a basis for monitoring, we will be using line-transect sampling. The timeframe for vegetation monitoring will be specified as 7 years. 5 - It is clear that there will be extensive grading done for TB4A. Can you describe the extent of grading to be done for other BDA features? The grading plan has been updated to remove TB1 and TBb from the plans, reducing the overall impact of grading. All other areas will be fine graded according to the Predicted Depth Maps. Grading activities will not encroach into the channel bottoms. Instead, the banks are being graded to allow for wider floodplains. Please feel free to reach out to me with additional questions or concerns.
