Determination Information Appendix D Mountain Sweet Pitcher Plant Reintroduction and Conservation Program Information Appendix E Historic Photographs • 1], 2 1.0 INTRODUCTION TO PROJECT The applicant, the Biltmore Company, proposes to complete a historic restoration of a series of ponds along Approach Road within the Biltmore Estate property. The project intent will be to restore the historic Approach Road "experience" when traveling to the Biltmore house on the estate property. The proposed project is based on Frederick Law Olmstead landscape architecture drawings from approximately 1891 (Appendix A). 1.1 Project Location The Biltmore ponds project site is located in Asheville, Buncombe County, North Carolina. To access the site from Asheville, take I-40 to Exit 50 (US Highway 25). Turn left onto US Highway 25 and follow signs to the Biltmore Estate. Once in the estate, follow Approach Road to the first bridge across Ram Branch. The downstream project boundary starts at this bridge and continues to the third bridge across Ram Branch. In general, the site is bordered to the north by Interstate 40, to the south by Cedarcliff Road, to the east by Vanderbilt Forest Road, and to the west by Deer Park Drive. A site vicinity map (Figure 1) and USGS topographic map (Figure 2) are attached for review. 1.2 Jurisdictional Waters Tributaries on site include Ram Branch and unnamed tributaries to Ram Branch. All of the streams within the Biltmore ponds project boundary are tributaries to the Swannanoa River. The Swannanoa River is a tributary to the French Broad • River, which is a navigable-in-fact water at the Wilson Bridge east of Brevard. Ram Branch makes up the largest hydrologic system on site and is classified by the NC Division of Water Quality (DWQ) as a class "C" water. There are several wetlands located on site. These wetlands have been identified as herbaceous and forested wetlands adjacent to Ram Branch and unnamed tributaries. Several of the wetlands are located at the upstream ends of existing ponds and in the locations of historic ponds. There are three existing on-line ponds located within the project boundary; all three are located at the downstream end of the project site. The table below summarizes the amounts of jurisdictional waters with the project boundary. Proiect Area Total, Feature Amount Unit Stream 2,270 linear feet Wetlands 0.39 acres Open Water 0.22 acres An "Existing Site Conditions" section (Section 3.0) has been included in this application for review and further describes the jurisdictional waters on site. 3 2.0 BACKGROUND/PRIOR PROJECT HISTORY Is A Nationwide permit was issued for a similar project upstream of the proposed project on November 15, 2007; Action ID 2007-01489-311. This Nationwide permit authorized impacts to approximately 0.17 acre of wetland and approximately 484 linear feet of stream for restoration activities including creation of floodplain benches and restoration of a historic pond. This permit authorization is attached for review (Appendix B). Ms. Starr Silvis of the DWQ visited the site on July 24, 2008 and Ms. Liz Hair of the US Army Corps of Engineers visited the site on October 7, 2008. • • 3.0 EXISTING SITE CONDITIONS The Biltmore ponds project site is located along Approach Road within the Biltmore Estate property boundary; the entire project will take place within approximately 100 feet of the road. Because Approach Road is the main thoroughfare to the Biltmore house, much of its length is landscaped and maintained. Many cultivated and native plant species are present within the project boundary. Species observed on site include oriental spruce (Picea orientalis), American beech (Fagus grandifolia), red maple (Ater rubrum), mountain laurel (Kalmia latifolia), jewelweed (Impatiens capensis), ground ivy (Glechoma hederacea), wingstem (Verbesina alternifolia), and Virginia creeper (Parthenocissus virginiana). Streams on site include Ram Branch and unnamed tributaries. There are approximately 2,270 linear feet of stream channels within the property boundary. In general, these tributaries flow south to north and eventually into the French Broad River via the Swannanoa River. The French Broad River is a navigable-in-fact water at the Wilson Bridge east of Brevard. Streams within the project boundary are bordered by infrastructure roads (paved and unpaved) and maintained landscapes. Stream channels and wetlands were delineated by ClearWater Environmental Consultants, Inc. (CEC) on May 7, 2008; and a survey of jurisdictional areas was completed by Brooks Engineering Associates during the latter half of May 2008. Streams channels have been identified on the site plan maps (Figure Set 3); and • associated data forms are included for review (Appendix Q. There are fourteen wetland areas located in the Biltmore ponds project boundary. These are forested and herbaceous wetlands that abut Ram Branch and unnamed tributaries. Wetlands have been identified on the site plan maps (Figure Set 3); and associated data forms are included for review (Appendix Q. Three impoundments exists on site. Two ponds impound unnamed tributaries to Ram Branch and are 0.08 acre and 0.04 acre, respectively. One pond impounds Ram Brach and is approximately 0.10 acre. All three ponds are located at the downstream end of the project reach. 3.1 Soils The Biltmore ponds project site is located within the Mountain physiographic region of North Carolina and more specifically the Broad Basins Ecoregions. Soil series present on site include: Evard-Cowee complex, French loam, and Tate loam. A soils map and legend have been attached for review (Figure 4). 3.2 Fish and Wildlife Use of the Proiect Site Wildlife species inhabiting the site include those typically found in the forest types of the region previously described. Although site-specific studies and inventories documenting species utilization of the Biltmore ponds project area have not been conducted, general observations of fish and wildlife use were 5 recorded during on-site meetings and field visits. Specifically, turkey and • songbirds have been seen utilizing the area. 3.3 Threatened and Endangered Species CEC has conducted a file review of records maintained by the US Fish and Wildlife Service (FWS) and North Carolina Natural Heritage Program (NHP). The desktop literature review involved a review of the FWS list of protected species in Buncombe County and the Asheville USGS Topographic Quad on which NHP identifies current and historic occurrences of listed species for that locale. The NHP database identifies 20 element occurrences (EO) within a 2-mile radius of the project site; four of the EOs hold Federal status and are subject to Section 7 consultation. These EOs are listed below. Common Name Sciendl is Name Status Appalachian elktoe Alasmidonta raveneliana Endangered - historic tan riffleshell Epioblasma florentina walkeri Endangered - extirpated spotfrn chub Erimonax monachus Threatened - extirpated gray myotis Myotis grisescens Endangered - extant -•--nistorrc - mere is no recent survey mtormathon to verity the continued existence of an EO previously reported. * *Extirpated - The EO is known to be destroyed. "Extant - The EO has recently been verified to still exist, but there is insufficient information to estimate is viability and ecological integrity. Suitable habitat for Appalachian elktoe, tan riffleshell, and spotfrn chub does not exist in the small streams on site. Additionally, according to NHP records, tan riffleshell and spotfin chub observation records are from the 1800s and the species are currently known to be extirpated in those locales. Gray myotis roost in caves and forage mainly over open water. Suitable habitat for the gray myotis is not present on the project site. Currently, five mountain sweet pitcher plants (Sarracenia jonesii) are present along Ram Branch. These individuals are a part of a pitcher plant reintroduction and conservation program at the Biltmore Estate. The pitcher plants were obtained from the Meadowview Biological Research Station and placed in wetland areas along Ram Branch. As a part of the reintroduction and conservation program, the Biltmore Estate maintains a monitoring and transplant program to ensure the health and survival of the pitcher plants at the estate. The mountain sweet pitcher plants are located within or in close proximity to wetlands proposed to be flooded. These plants will be relocated during the dormant season to another wetland with an existing and viable population of pitcher plants, also planted by the estate, prior to construction activities on site. The proposed activities within the Biltmore ponds project boundary will not impact the mountain sweet pitcher plants. The Biltmore Estate takes pride in the presence of the mountain sweet pitcher plant within estate property and would do nothing to jeopardize their existence or the integrity of the reintroduction and conservation program. As a public garden, it is in the Biltmore Estate's best interest to 6 maintain and protect the mountain sweet pitch plants. Documentation of the • conservation and reintroduction program is included for review (Appendix D). It is the opinion of CEC that Appalachian elktoe, tan riffleshell, spotfin chub, and gray myotis are not likely to be present within the project boundary. Mountain sweet pitcher plant is present only through the actions of the estate as they participate in the pitcher plant conservation and reintroduction program. As such, activities within the proposed Biltmore ponds project boundary are not likely to cause an adverse impact to any federally threatened or endangered species or their critical habitat. 3.4 Cultural Resources A desk review of the National Register of Historic Places records maintained by the State Historic Preservation Office (SHPO) identifies the Biltmore estate and several buildings in the vicinity of the estate as historic properties. The intent of the proposed project is historic restoration of the site. Estate personnel work closely with the SHPO on a regular basis to ensure projects are in compliance with rules and regulations regarding historic properties and cultural resources. It is the opinion of CEC that registered properties, or properties listed as being eligible for inclusion, will not be affected by the proposed activities. The SHPO will be notified via Public Notice about the project and will be given the opportunity to comment on the project and its potential affects on archaeological and cultural resources at the site. E 0 4.0 PROJECT PURPOSE The basic project purpose of the proposed activities within the Biltmore ponds project boundary is historic restoration. More specifically, the overall project purpose of the proposed activities within the Biltmore ponds project boundary is to restore historic conditions along Approach Road at the Biltmore Estate in accordance with Fredrick Law Olmstead landscape architecture drawings from approximately 1891 (Appendix A). • 8 5.0 PROPOSED PROJECT DEVELOPMENT • The proposed project calls for the historic restoration of 13 ponds, two stream relocations, and construction of one horse ford along Approach Road. Three ponds are currently existing on site and the locations of all historic ponds can be seen on the historic maps included for review (Appendix A). Eleven low profile dams (two dams are pre- existing) will be constructed to impounded water at the site; three of these low profile dams will be constructed on high ground. Eight small dams will be placed in stream channels with a total of 48 linear feet of jurisdictional impact associated with their construction. The applicant proposes to permanently impact 1,117 linear feet of stream channel, 0.16 acre of wetland, and 0.04 acre of open water to achieve the previously stated project purpose. There are 23 permanent stream impacts, eight permanent wetland impacts, and two open water impacts associated with activities within the project boundary. Impacts have been identified on the site plan, which is enclosed for review (Figure Set 3). C] • 9 5.1 Stream Impacts • The project will include 23 permanent stream impacts associated with construction of a horse ford, construction of small dams and impoundments, and the relocation of two stream segments. Hard impacts associated with construction of the horse ford, dam construction, and stream relocations total 216 linear feet of stream channel. Flooding impacts total 901 linear feet of streams channel. Permanent stream impacts associated with this project are identified in the table below.

An analysis of the Section 404(b)(1) Guidelines (Guidelines) requirements for consideration of alternatives as required by 40 C.F.R. 230.10(a) is set forth below. The Guidelines' alternatives requirements provide that "no discharge of dredged or fill material shall be permitted if there is a practicable alternative to the proposed discharge which would have less adverse impact on the aquatic ecosystem, so long as the alternative does not have other significant adverse environmental consequences." [See 40 C.F.R. 230.10(a) (emphasis added).] The record must contain "sufficient information to demonstrate that the proposed discharge complies with the requirements of Section 230.10(a) of the Guidelines. The amount of information needed to make such a determination and the level of scrutiny required by the Guidelines is commensurate with the severity of the environmental impact (as determined by the functions of the aquatic resource and the nature of the proposed activity) and the scope/cost of the project." [See Corps/EPA Memorandum to the Field "Appropriate Level of Analysis Required for Evaluating Compliance with Section 404(b)(1) Guidelines Alternatives Requirements," p. 2, dated August 23, 1994, hereinafter the "Memorandum."] As noted in the Memorandum on pages 3-4, the 404(b)(1) Guidelines "only prohibits discharges when a practicable alternative exists which would have less adverse impact on the aquatic ecosystem." [See Memorandum.] "If an alleged alternative is unreasonably expensive to the applicant, the alternative is not practicable." [See Guidelines Preamble, "Economic Factors," 45 Federal Register 85343 (December 24, 1980).] Practicable alternatives for the project are those alternatives that are "available and capable of being done after taking into consideration costs, existing technology, and logistics in light of overall project purposes." [See 40 C.F.R. 230.10(a)(2).] Clarification is provided in the Preamble to the Guidelines on how cost is to be considered in the determination of practicability. An alternative site is considered "available" if it is presently owned by the applicant or "could reasonably be obtained, utilized, expanded or managed in order to fulfill the basic purpose of the proposed activity." 40 C.F.R. § 230.10(a)(2). The intent is to consider those alternatives, which are reasonable in terms of the overall scope and cost of the proposed project. The term economic [for which the term "costs" was substituted in the final rule] might be construed to include consideration of the applicant's financial standing, or investment, or market share, a cumbersome inquiry which is not necessarily material to the objectives of the Guidelines. • 12 The Environmental Protection Agency (EPA) 404(b)(1) Guidelines state that, "we have • chosen instead to impose an explicit, but rebuttable presumption that alternatives to discharges in special aquatic sites are less damaging to the aquatic ecosystem, and are environmentally preferable." Of course, the general requirements that impacts to the aquatic system not be acceptable also applies. This presumption "...contains sufficient flexibility to reflect circumstances of unusual cases" (249 Fed. Reg., 85339, December 24, 1980). It is clear from these stipulations that a preferable alternative may allow filling in certain wetland areas and subsequent mitigation and/or management of other areas. 6.1 Avoidance The proposed project is location specific and based on actual historic drawings of the project area (Appendix A) that were used for construction; therefore no other parts of the estate or other project areas where considered for this project. Alternative project designs, conceptual in nature, were considered and are discussed below. 6.1.1 No-Build A true historic restoration of the project area cannot be completed without impacts to jurisdictional waters. Historic drawings (Appendix A) illustrate on-line impoundments and in-stream rock features. Several historic photographs of the impoundments have been included for review (Appendix E). • Because true historic restoration of the project area includes on-line impoundments, the no-build alternative is not the preferred alternative. 6.1.2 Construction of One Large Pond Construction of one large pond is not a feasible option for the site. The project boundary crosses Approach Road twice and another gravel road (Sawmill Road) once. This causes the project area to be divided into four sections. One large pond could be put in one of those sections; however, would not restore the site to historic conditions. Furthermore, this option would require a larger dam at the pond location. Dams currently proposed will be aesthetically pleasing, small, low profile dams made and/or faced with stone and cobble. A larger dam would have a more "engineered" look and not provide aesthetic benefit to the site. Because construction of one large pond would require construction of a larger dam and not meet the project purpose of historic restoration, this alternative is not the preferred alternative. • 13 6.1.3 Construction of Off-line Ponds • Where off-line ponds are a viable option and meet the project purpose, they are proposed (i.e. ponds I, J, and K). Construction of off-line ponds in other areas within the project boundary proves difficult at this location. There is minimal topographic relief within the project boundary and gravity fed inlets and outlet may not work efficiently without mechanical means. Additionally, the project is located entirely within the existing road corridor, which is very narrow. In some cases, there is as little as 20 feet between the stream and the road; and the stream and the toe-of-slope. This narrow corridor does not lend itself to off-line ponds that meet the applicant's stated project purpose. Because the project corridor is very narrow and topographic relief is at a minimum, the construction of off-line ponds is not the preferred alternative. 6.1.4 Project As Prouosed The proposed project calls for the historic restoration of 13 ponds, two stream relocations, and construction of one horse ford along Approach Road. Three ponds are currently existing on site and the locations of all historic ponds can be seen on the historic maps included for review (Appendix A). Eleven low profile dams (two dams are pre-existing) will be constructed to impounded water at the site; three of these low profile dams will be constructed on high ground. Eight small dams will be placed in stream channels with a total of 48 linear feet of jurisdictional impact associated with their construction. The applicant proposes to permanently impact 1,117 linear feet of stream channel, 0.16 acre of wetland, and 0.04 acre of open water to achieve the previously stated project purpose. There are 23 permanent stream impacts, eight permanent wetland impacts, and two open water impacts associated with activities within the project boundary. Impacts have been identified on the site plan, which is enclosed for review (Figure Set 3). 6.2 Minimization Because the project constitutes a historic restoration, the design is modeled closely after Frederick Law Olmstead landscape architecture drawings from 1981. All ponds proposed for this project were constructed and existed or are still existing on the estate. Photographs of some of these historic pond are included for review (Attachment Q. For reasons unknown to current estate personnel, some of the ponds where decommissioned. Additional liberties were not taken with this design; ponds where not made larger and additional ponds, beyond what is on historic drawings, are not proposed. • 14 6.3 Alternatives Conclusion This discussion of alternatives, together with the documents submitted by the applicant in support of the 404 Permit, show that the project is in compliance with the Guidelines. As this analysis clearly demonstrates, the Biltmore ponds project has been designed to avoid and minimize impacts to the site to the maximum extent practicable while maintaining a rational project design that is true to the historic condition of the site. 17? • 15 7.0 CONCEPTUAL MITIGATION PLAN • Because this project constitutes a historic restoration and all ponds proposed are well documented as having existed at the site, no mitigation is being proposed for this project. Remnants of old dams are present at the site and the locations of wetlands coincide with the locations of the historic ponds. Historic photographs and landscape architecture drawings are included for review (Appendix A and E). • E 16 8.0 US ENVIRONMENTAL PROTECTION AGENCY 404(b)(1) GUIDELINES • The EPA interim regulations providing guidance for specification of deposit on sites for dredge and fill material were published on September 17, 1993, in 40 C.F.R. 230 per Section 404(b)1. Sub-Parts A through I pertain to dredge and fill permits, and apply to project sites similar to this project. Sub-Part . D presents a summary of compliance criteria for the 404(b)l guidelines. This section references and defines practicable alternatives and indicates that a dredge and fill permit shall not be issued if practicable alternatives exist. Alternatives reviewed, detailed in Section 6.0, were assessed for compliance with 404(b)1 guidelines. Additional EPA guidance is presented related to general regulatory criteria, wildlife value, and human health guidelines. The discharge of dredge and fill material is considered permittable under these guidelines if the discharge activity: does not contribute to violation of state water quality standards; does not violate toxic effluent standards; does not jeopardize the continued existence of species listed as threatened and endangered pursuant to the federal Endangered Species Act of 1973 and subsequent amendments; does not cause degradation to any marine sanctuaries; does not contribute to significant degradation of "waters of the United States;" does not adversely affect human health as it pertains to water supply; does not adversely impact wildlife, the food chain, and special aquatic sites; does not contribute to the discharge of pollutants that may affect the food web; does not have negative effects on the productivity of the aquatic • ecosystem, or their physical values; and does not have adverse impacts on recreation, aesthetic, or economic values. Additionally, the applicant is required to minimize potential adverse impacts on the aquatic ecosystem. 8.1 Factual Determination The Corps is required to determine both potential short-term and long-term effects of a proposed discharge of dredge and fill material on the physical, chemical, and biological components of an aquatic environment. 8.2 Potential Impacts on Physical and Chemical Characteristics of the Aquatic Ecosystem Sub-Part C of the 40 C.F.R. 230 guidelines lists six physical and chemical characteristics that must be assessed during the permit review, and the effects of which must be determined to be minimal on the aquatic ecosystem. 8.2.1 Substrate Fill material in the form of dams will be placed in jurisdictional streams on site. Any discharge will consist of suitable fill material and will not include any trash, debris, car bodies, asphalt, etc. The fill material will also be free of toxic pollutants in toxic amounts. Proper sediment and erosion control measures will be installed prior to and during construction to ensure that the bottom elevation of remaining streams and wetlands on the property will not change. 17 • 8.2.2 Suspended Particulate/Turbidity (Sediment and Erosion Control) During construction activities on the site, there may be a minimal increase in suspended particulates that may lead to increased turbidity downstream. However, the increase is anticipated to be minimal and temporary due to the installation and maintenance of proper sediment and erosion control measures during construction and shortly thereafter. 8.2.3 Water Quality The proposed discharge of dredge and fill material should not cause increased chemical contamination levels within the aquatic ecosystem. Specifically, changes in clarity, color, odor, and taste of water in addition to possible chemical contamination shall be minimized or reduced. All discharges of dredge and fill material will be controlled with a sediment and erosion control plan. It is anticipated that all of the fill material needed at the site will be taken from on-site areas. The fill material used on site will be clear and free of chemical contamination. Should additional fill material be required, suitable, off-site, clean fill material will be purchased and transported to the project. The applicant will be concurrently applying for a NC Division of Water • Quality, Water Quality Certification. 8.2.4 Current Patterns in Water Circulation The discharged dredge and fill material will adversely modify current water circulation patterns by obstructing flow through the use of dams to create impoundments. All proposed impoundments are impoundments that were existing at the site and three of the proposed impoundments are currently existing at the site. Remnants of old dams can be seen throughout the project reach. 8.2.5 Normal Water Fluctuations The discharge of fill material associated with this project is not anticipated to have any significant effect on the downstream hydrologic regimes. Ponds will be designed to outlet water during low flow and drought conditions; water will not be cut-off from the stream channel at any time. 8.2.6 Salinity Because this project is located inland and away from tidally influenced waters and wetlands, no modification to the salinity of on-site or adjacent waters is expected. • 18 8.3 Potential Impacts to Biological Characteristics of the Ecosvstem • Sub-Part D of the 40 C.F.R. 230 guidelines specifies three areas of concern in which disposal of dredge and fill material can affect the biological components of the ecosystem. These components are threaten and endangered species; fish, crustaceans, mollusks, other aquatic organisms in the food web; and wildlife. 8.3.1 Threatened or Endangered Species CEC has conducted a file review of records maintained by the FWS and NHP. The desktop literature review involved a review of the FWS list of protected species in Buncombe County and the Asheville USGS Topographic Quad on which NHP identifies current and historic occurrences of listed species for that locale. The NHP database identifies 20 EOs within a 2-mile radius of the project site; four of the EOs hold Federal status and are subject to Section 7 consultation. These EOs are listed below. Common Name Scientific Name Status Appalachian elktoe Alasmidonta raveneliana Endangered - historic tan riffleshell Epioblasma florentina walkeri Endangered - extirpated spotfin chub Erimonax monachus Threatened - extirpated gray myotis Myotis grisescens Endangered - extant •Trnistoric - inere is no recent survey mtormation to verify the continued existence of an EO previously reported. • "Extirpated - The EO is known to be destroyed. "Extant - The EO has recently been verified to still exist, but there is insufficient information to estimate is viability and ecological integrity. Suitable habitat for Appalachian elktoe, tan riffleshell, and spotfin chub does not exist in the small streams on site. Additionally, according to NHP records, tan riffleshell and spotfin chub observation records are from the 1800s and the species are currently known to be extirpated in those locales. Gray myotis roost in caves and forage mainly over open water. Suitable habitat for the gray myotis is not present on the project site. Currently, five mountain sweet pitcher plants (Sarracenia jonesii) are present along Ram Branch. These individuals are a part of a pitcher plant reintroduction and conservation program at the Biltmore Estate. The pitcher plants were obtained from the Meadowview Biological Research Station and placed in wetland areas along Ram Branch. As a part of the reintroduction and conservation program, the Biltmore Estate maintains a monitoring and transplant program to ensure the health and survival of the pitcher plants at the estate. The mountain sweet pitcher plants are located within or in close proximity to wetlands proposed to be flooded. These plants will be relocated during the dormant season to another wetland with an existing and viable population of pitcher plants, also planted by the estate, prior to construction activities on site. The proposed activities within the Biltmore ponds project boundary will not impact the mountain 19 sweet pitcher plants. The Biltmore Estate takes pride in the presence of the mountain sweet pitcher plant within estate property and would do nothing to jeopardize their existence or the integrity of the reintroduction and conservation program. As a public garden, it is in the Biltmore Estate's best interest to maintain and protect the mountain sweet pitch plants. Documentation of the conservation and reintroduction program is included for review (Appendix D). It is the opinion of CEC that Appalachian elktoe, tan riffleshell, spotfin chub, and gray myotis are not likely to be present within the project boundary. Mountain sweet pitcher plant is present only through the actions of the estate as they participate in the pitcher plant conservation and reintroduction program. As such, activities within the proposed Biltmore ponds project boundary are not likely to cause an adverse impact to any federally threatened or endangered species or their critical habitat. 8.3.2 Fishes, Crustaceans, Mollusks, and other Aquatic Organisms in the Food Web Discharges of dredge and fill material can alter the food web by impacting animals, such as invertebrates, that make up the basis of a food chain. The release of contaminants or an increase in turbidity has the potential to negatively effect certain aspects of the food web. Such releases may also potentially increase the levels of exotic species. Any discharge will consist of suitable fill material and will not include any trash, debris, car bodies, asphalt, etc. The fill material will also be free of toxic pollutants in toxic amounts. Proper sediment and erosion control measures will be installed prior to and during construction to ensure impacts to the food web do not occur. Impacts to primary food chain production within the waters of the US and wetlands on the project site is expected to be minimal. 8.3.3 Other Wildlife The discharge of dredge and fill material has the potential to negatively effect breeding and nesting areas, escape cover, travel corridors, and preferred food sources for resident and migrant wildlife species. The project as proposed will not effect breeding and nesting areas, escape cover, travel corridors, or food sources for resident and migrant wildlife species. 8.4 Potential Impacts on Special Aquatic Sites Sub-Part E of the 40 C.F.R. 230 guidelines addresses considerations for potential impacts on special aquatic sites, which include: sanctuaries and refuges, wetlands, mud flats, vegetated shallows, coral reefs, and riffle-pool complexes. 20 8.4.1 Sanctuaries and Refuges The discharge of dredge and fill material has the potential to negatively effect adjacent sanctuaries and wildlife refuges by impacting water quality, decreasing wildlife habitat, increasing human access, and creating the need for frequent maintenance activity, resulting in the establishment of undesirable plant and animal species, which can change the balance of habitat type. There are no designated sanctuaries of refuges located within the project vicinity; therefore, impacts to sanctuaries or refuges will not occur as a result of activities within the Biltmore ponds project area. 8.4.2 Wetlands The discharge of dredge and fill material has the potential to adversely effect wetlands including wetland substrate, hydrology, and vegetation. Discharges can lead to a loss of wetland values, such as wildlife habitat, flood storage, and groundwater recharge. The discharge of fill material associated with development within the Biltmore ponds project area will impact 0.16 acre of wetlands on site. 8.4.3 Mud Flats Discharge of dredge and fill material has the potential to negatively effect mud flats that exist along inland lakes, ponds, and riverine systems. There are no mud flat communities within the project boundary; therefore, loss of these ecosystems will not occur as a result of activities within the Biltmore ponds project boundary. 8.4.4 Vegetated Shallows Discharge of dredge and fill material has the potential to negatively effect vegetated shallows. Vegetated shallows are permanently inundated areas that contain rooted aquatic vegetation. This type of habitat generally exists within estuarine and marine environments; and some freshwater lakes and rivers. No vegetated shallow habitats exist within the project boundary; therefore, no impacts to this ecosystem will occur as a result of activities within the Biltmore ponds project boundary. 8.4.5 Coral Reefs Discharge of dredge and fill material has the potential to negatively effect coral reefs. Coral reefs typically exist within marine ecosystems. Coral reefs do not exist within the project boundary; therefore, no impacts to this ecosystem will occur as a result of activities within the Biltmore ponds project boundary. 8.4.6 Riffle-Pool Complexes Discharge of dredge and fill material into or upstream of riffle-pool complexes has the potential to negatively affect water quality and wildlife value. Fill in the form of dams has the potential to be placed into riffle- 21 pool complexes; however, all proposed impoundments are impoundments that were existing at the site and three of the proposed impoundments are currently existing at the site. Remnants of old dams can be seen throughout the project reach. 8.5 Potential Effects on Human Use Characteristics Sub-Part F of the 40 C.F.R. 230 guidelines address potential effects on human use of wetlands and waterways. Factors including water supply, recreational and commercial fisheries, water-related recreation, aesthetics, and parks and similar preserves are considered within this portion of the guidelines. 8.5.1 Municipal and Private Water Supply The public water supply will not increase or decrease due to proposed activities within the Biltmore ponds project area. 8.5.2 Recreational and Commercial Fisheries Discharge of dredge and fill material has the potential to negatively effect recreational and commercial fisheries. Recreational and commercial fisheries are not located within the Biltmore ponds project boundary; therefore recreational and commercial fisheries will not be impacted as a result of activities within the Biltmore ponds project boundary. 8.5.3 Water-Related Recreation Proposed activities within the Biltmore ponds project area will not increase or decrease waterborne recreation in the project area or vicinity. 8.5.4 Aesthetics The Biltmore ponds project will be aesthetically consistent with other projects currently taking place at the Biltmore Estate. Because some of the goals of the Biltmore Estate are preserving and showcasing the house and grounds, an aesthetically pleasing design is of utmost importance. The design team has strived to develop a plan that meets both goals, while enhancing the visitor's approach to the estate. The project is not expected to diminish the aesthetic value of the area or cause disharmony from an aerial or neighboring view. 8.5.5 Parks, National and Historical Monuments, National Beach Shores, Wilderness Areas, Research Sites, and Similar Preserves No areas as described above will be effected by the proposed activities within the Biltmore ponds project area. 8.6 Summary Based on the EPA guidelines identified within 40 C.F.R. 230, and enumerated herein, a number of potential environmental impacts have been presented and subsequently addressed. The proposed permanent impact to 1,117 linear feet of 9 streams and 0.16 acre of wetland will not cause any off site adverse impacts 22 9.0 PUBLIC INTEREST CONSIDERATIONS When reviewing this application, the Corps is required to consider the project in terms of the public interest. In considering the public interest, the Corps must evaluate the probable impacts of the project and evaluate the "benefits which reasonably may be expected to occur from the proposal against reasonably foreseeable detriments". In balancing these interests, the Corps must consider the public and private need for the proposed project, the practicability of using reasonable alternative locations, and the extent and permanence of the beneficial and/or detrimental impacts of the project. The Corps also considers the following public interest factors: conservation, economics, aesthetics, general environmental concerns, wetlands, historic and cultural resources, fish and wildlife values, flood hazards, floodplain values, land use, navigation, shore erosion and accretion, recreation, water supply and water quality, energy needs, safety, food and fiber production, mineral needs, and considerations of the property ownership. Pursuant to 33 C.F.R. 323.6, a determination that the project is not contrary to the public interest must be achieved before permit issuance. Public interest considerations are listed in 33 C.F.R. 320.4 (a)(1) and are discussed below. Furthermore, the Corps regulations state that a permit will be granted unless the district engineer determines that it would be contrary to the public interest. 9.1 Conservation The applicant is not proposing preservation as a component of the Biltmore ponds project. 9.2 Economics The project will provide an overall benefit to the local economy of Buncombe County and Asheville. During and upon completion of construction, the site will provide job opportunities associated with maintenance of the area. The project will also benefit the local economy by providing additional tax revenues from tourist visiting the Biltmore estate and surrounding areas. The appropriate economic evaluations have been completed and the project as proposed is economically viable. 9.3 Aesthetics The Biltmore ponds project will be aesthetically consistent with other projects currently taking place at the Biltmore Estate. Because some of the goals of the Biltmore Estate are preserving and showcasing the house and grounds, an aesthetically pleasing design is of utmost importance. The design team has strived to develop a plan that meets both goals, while enhancing the visitor's approach to the estate. The project is not expected to diminish the aesthetic value of the area or cause disharmony from an aerial or neighboring view. 23 9.4 General Environmental Concerns Other than stream and wetland impacts, proposed activities within the Biltmore ponds project area will have no significant identifiable impacts upon other environmental components. 9.5 Wetlands The discharge of dredge and fill material has the potential to adversely effect wetlands including wetland substrate, hydrology, and vegetation. Discharges can lead to a loss of wetland values, such as wildlife habitat, flood storage, and groundwater recharge. The discharge of fill material associated with development within the Biltmore ponds project area will impact 0.16 acre of wetlands on site. 9.6 Historic Properties A desk review of the National Register of Historic Places records maintained by the SHPO identifies the Biltmore Estate and several buildings in the vicinity of the estate as historic properties. The intent of the proposed project is historic restoration of the site. Estate personnel work closely with the SHPO on a regular basis to ensure projects are in compliance with rules and regulations regarding historic properties and cultural resources. It is the opinion of CEC that registered properties, or properties listed as being eligible for inclusion, will not be affected by the proposed activities. The SHPO will be notified via Public Notice about the project and will be given the opportunity to comment on the project and its potential affects on archaeological and cultural resources at the site. 9.7 Fish and Wildlife Values Riparian and wetland areas provide habitat for many types of wildlife because of their diverse and productive plant communities, complex structure, and close proximity to surface water. Wildlife may be permanent residents of riparian and wetland areas or occasional visitors that use the areas for food, water, or temporary shelter. Food availability varies with the type of vegetation in riparian and wetland areas, but includes fruit, seed, foliage, twigs, buds, insects, and other invertebrates. Trees and shrubs produce a variety of foods that are eaten by many animals and may be especially important sources of nutrition during the winter months. Grasses and herbaceous vegetation provide seeds and forage both within riparian and wetland areas and along the forest border. The stream environment provides moving water for many animals to drink, feed, swim, and reproduce. Water is also available on moist vegetation and in wetlands that are often associated with riparian areas. • 24 These areas, both permanent and temporary, are especially important for amphibians and macro-invertebrates. Riparian and wetland areas provide a sheltered environment for many species of animals to feed, rest, and reproduce. Animals use these areas to seek shelter from extreme weather and to escape predators and human activity. Riparian and wetland areas may also provide important travel corridors for some species, and are frequently used as stop-over points for migratory birds. Fish and wildlife values at the site are already compromised and will not significantly be diminished. The entire stream and pond corridor lies within 100 feet of Approach Road. Additionally, a majority of the riparian area is sparse, absent, or heavily maintained and manicured. 9.8 Flood Hazards It is likely that some tributaries on the property will flood occasionally due to natural fluctuations in weather patterns that increase precipitation. The activities taking place within the Biltmore ponds project boundary are not expected to increase or decrease the natural rate of flooding at the site or downstream. 9.9 Floodplain Values Designated floodplains will not be impacted by activities within the Biltmore ponds project boundary. The project is not located within the 100-year floodplain; an excerpt from the Flood Insurance Rate Map has been included for review (Figure 5). Flood stages and frequencies should not increase or decrease as a result of the activities taking place within the Biltmore ponds project boundary. 9.10 Land Use The proposed project will be in compliance with local zoning regulations and ordinances. The project is consistent with surrounding land use and development. 9.11 Navigation All streams on site are tributaries to Ram Branch. Ram Branch is a tributary to the Swannanoa River, which is a tributary to the French Broad River. The French Broad River is a navigable-in-fact water at the Wilson Bridge east of Brevard. Activities proposed within the Biltmore ponds project boundary are not likely to effect navigation. a 25 9.12 Shore Erosion and Accretion The project should have minimal effects on erosion and runoff. During the construction process, best management practices (BMPs) will be followed. These BMPs may include the construction of swales, erosion and sediment control structures, turbidity barriers, and other measures that will prevent sediment transport off the project site and into adjacent waters. Activities proposed within the Biltmore ponds project area are not likely to cause significant erosion or accretion. 9.13 Recreation Proposed activities within the Biltmore ponds project boundary will not increase or decrease waterborne recreation within the project boundary. 9.14 Water Supply and Conservation The public water supply will not increase or decrease due to proposed activities within the Biltmore ponds project boundary. 9.15 Water Quality (Stormwater Management) No short term or long term adverse water quality impacts are anticipated. BMPs will be incorporated during construction. The applicant will be concurrently applying for a NC Division of Water Quality, Water Quality Certification. 9.16 Energy Needs Activities taking place within the Biltmore ponds project boundary will not increase energy demands. Energy will not be produced as a result of the proposed activities within the Biltmore ponds project boundary. 9.17 Safety The proposed project will be designed with the maximum possible considerations for public safety. The proposed activities within the Biltmore ponds project boundary will not increase or decrease public safety. 9.18 Food and Fiber Production The proposed activities within the Biltmore ponds project boundary will not increase or decrease food and fiber production. 9.19 Mineral Needs The project fulfills no current mineral needs. No mining activities are proposed as part of the activities within the Biltmore ponds project boundary. • 26 9.20 Considerations of Property Ownership The Biltmore Company owns the property proposed for development and has the inherent right to develop the land in a reasonable and responsible manner, which includes adhering to all Federal, State, and local regulations. Property Owner: The Biltmore Company 1 North Pack Square, Suite 400 Asheville, North Carolina 28801 9.21 Needs and Welfare of the Public The project will positively address the needs and welfare of the public by further restoring and preserving the Biltmore estate for future visitors and tourist that add to the tax base of Asheville and Buncombe County, North Carolina. • • 27 10.0 SECONDARY AND CUMULATIVE EFFECTS The Biltmore ponds project site is located within the French Broad River Subbasin 04-03- 02. Approximately 75 percent of this subbasin is forested and the total land mass includes approximately 806 square miles (516,000 acres). The Biltmore ponds project area is comprised of approximately 20 acres (0.03 square miles). All of the land mass included within the Biltmore ponds project site accounts for less than 0.004 percent of the land mass of the basin. These percentages alone, limit significant cumulative effects on the watershed. Past activities within the subbasin include logging; agricultural, commercial, and residential development; and road building. Agricultural and residential development, and road building in the vicinity remains active; continued and future development of the watershed is independent of activities proposed within the Biltmore ponds project boundary. Impacts within the Biltmore ponds project boundary include the installation of dams and subsequent flooding, the construction of a horse ford, and the relocation of two stream segments. Stream and wetland impacts are necessary for the construction at the site. Activity within the Biltmore ponds project boundary should not result in a significant impairment of the water resources on site or interfere with the productivity and water quality of the existing aquatic ecosystem. • • 28 11.0 SUMMARY • Historic restoration activities within the Biltmore ponds project boundary involve p ? the construction of one horse ford, the relocation of two stream segments, and the construction and/or rehabilitation of 13 historic ponds. Because the project is site specific, few alternatives exist for this site; however, alternative site plans have been evaluated and the project "As-Proposed" is the least damaging practical alternative, which meets the project purpose. Potential impacts to the physical and chemical characteristics of the ecosystem, biological characteristic of the ecosystem, impacts on special aquatic sites, and potential effects on human use characteristics will be minimal. The project is not contrary to the public interest. E • 29 MAPQVEST -,' meadow Rd . ? Ra act e? °a a? c 0 ® 2008 Mapou"t Inc.

Potentially jurisdictional waters and/or wetlands were assessed within the review area and determined to be not jurisdictional. Explain: Boxes checked below shall be supported by completing the appropriate sections in Section 111 below. For purposes of this form, an RPW is defined as a tributary that is not a TNW and that typically flows year-round or has continuous flow at least "seasonally" (e.g., typically 3 months). ' Supporting documentation is presented in Section III.F. SECTION III: CWA ANALYSIS A. TNWs AND WETLANDS ADJACENT TO TNWs • The agencies will assert jurisdiction over TNWs and wetlands adjacent to TNWs. If the aquatic resource is a TNW, complete Section HI.A.1 and Section M.D.I. only; if the aquatic resource is a wetland adjacent to a TNW, complete Sections HI.A.1 and 2 and Section HI.D.1.; otherwise, see Section HI.B below. TNW Identify TNW: Summarize rationale supporting determination: Wetland adjacent to TNW Summarize rationale supporting conclusion that wetland is "adjacent": B. CHARACTERISTICS OF TRIBUTARY (THAT IS NOT A TNW) AND ITS ADJACENT WETLANDS (IF ANY): This section summarizes information regarding characteristics of the tributary and its adjacent wetlands, if any, and it helps determine whether or not the standards for jurisdiction established under Rapanos have been met. The agencies will assert jurisdiction over non-navigable tributaries of TNWs where the tributaries are "relatively permanent waters" (RPWs), i.e. tributaries that typically flow year-round or have continuous flow at least seasonally (e.g., typically 3 months). A wetland that directly abuts an RPW is also jurisdictional. If the aquatic resource is not a TNW, but has year-round (perennial) flow, skip to Section HI.D.2. If the aquatic resource is a wetland directly abutting a tributary with perennial flow, skip to Section HI.D.4. A wetland that is adjacent to but that does not directly abut an RPW requires a significant nexus evaluation. Corps districts and EPA regions will include in the record any available information that documents the existence of a significant nexus between a relatively permanent tributary that is not perennial (and its adjacent wetlands if any) and a traditional navigable water, even though a significant nexus finding is not required as a matter of law. If the waterbody° is not an RPW, or a wetland directly abutting an RPW, a JD will require additional data to determine if the waterbody has a significant nexus with a TNW. If the tributary has adjacent wetlands, the significant nexus evaluation must consider the tributary in combination with all of its adjacent wetlands. This significant nexus evaluation that combines, for analytical purposes, the tributary and all of its adjacent wetlands is used whether the review area identified in the JD request is the tributary, or its adjacent wetlands, or both. If the JD covers a tributary with adjacent wetlands, complete Section HI.B.1 for the tributary, Section HI.B.2 for any onsite wetlands, and Section HI.B.3 for all wetlands adjacent to that tributary, both onsite and offsite. The determination whether a significant nexus exists is determined in Section HI.C below. 1. Characteristics of non-TNWs that flow directly or indirectly into TNW (i) General Area Conditions: Watershed size: Pick List Drainage area: Pick List Average annual rainfall: inches Average annual snowfall: inches (ii) Physical Characteristics: (a) Relationship with TNW: ? Tributary flows directly into TNW. ? Tributary flows through Pick List tributaries before entering TNW. Project waters are Pick List river miles from TN W. Project waters are Pick List river miles from RPW. Project waters are Pick List aerial (straight) miles from TNW. Project waters are Pick List aerial (straight) miles from RPW. Project waters cross or serve as state boundaries. Explain: Identify flow route to TNW5: Tributary stream order, if known: *Note that the Instructional Guidebook contains additional information regarding swales, ditches, washes, and erosional features generally and in the and West. 5 Flow route can be described by identifying, e.g., tributary a, which flows through the review area, to flow into tributary b, which then flows into TNW. (b) General Tributary Characteristics (check all that apply): Tributary is: ? Natural • ? Artificial (man-made). Explain: ? Manipulated (man-altered). Explain: Tributary properties with respect to top of bank (estimate): Average width: feet Average depth: feet Average side slopes: Pick List. Primary tributary substrate composition (check all that apply): ? Silts ? Sands ? Cobbles ? Gravel ? Bedrock ? Vegetation. Type/% cover: ? Other. Explain: ? Concrete ?

Explain: the presence of litter and debris destruction of terrestrial vegetation the presence of wrack line sediment sorting scour multiple observed or predicted flow events abrupt change in plant community If factors other than the OHWM were used to determine lateral extent of CWA jurisdiction (check all that apply): ? High Tide Line indicated by: ? Mean High Water Mark indicated by: ? oil or scum line along shore objects ? survey to available datum; ? fine shell or debris deposits (foreshore) ? physical markings; ? physical markings/characteristics ? vegetation lines/changes in vegetation types. ? tidal gauges ? other (list): (iii) Chemical Characteristics: Characterize tributary (e.g., water color is clear, discolored, oily film; water quality; general watershed characteristics, etc.). Explain: Identify specific pollutants, if known: natural or man-made discontinuity in the OHWM does not necessarily sever jurisdiction (e.g., where the stream temporarily flows underground, or where the OHWM has been removed by development or agricultural practices). Where there is a break in the OHWM that is unrelated to the waterbody's flow regime (e.g., flow over a rock outcrop or through a culvert), the agencies will look for indicators of flow above and below the break. ']bid. (iv) Biological Characteristics. Channel supports (check all that apply): ? Riparian corridor. Characteristics (type, average width): ? Wetland fringe. Characteristics: • ? Habitat for: ? Federally Listed species. Explain findings: ? Fish/spawn areas. Explain findings: ? Other environmentally-sensitive species. Explain findings: ? Aquatic/wildlife diversity. Explain findings: 2.

For each wetland, specify the following: Directly abuts? (Y/N) Size (in acres) Directly abuts? (Y/N) Size (in acres) S Summarize overall biological, chemical and physical functions being performed: C. SIGNIFICANT NEXUS DETERMINATION A significant nexus analysis will assess the flow characteristics and functions of the tributary itself and the functions performed by any wetlands adjacent to the tributary to determine if they significantly affect the chemical, physical, and biological integrity of a TNW. For each of the following situations, a significant nexus exists if the tributary, in combination with all of its adjacent wetlands, has more than a speculative or insubstantial effect on the chemical, physical and/or biological integrity of a TNW. Considerations when evaluating significant nexus include, but are not limited to the volume, duration, and frequency of the flow of water in the tributary and its proximity to a TNW, and the functions performed by the tributary and all its adjacent wetlands. It is not appropriate to determine significant nexus based solely on any specific threshold of distance (e.g. between a tributary and its adjacent wetland or between a tributary and the TNW). Similarly, the fact an adjacent wetland lies within or outside of a floodplain is not solely determinative of significant nexus. Draw connections between the features documented and the effects on the TNW, as identified in the Rapanos Guidance and discussed in the Instructional Guidebook. Factors to consider include, for example: • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to cant' pollutants or flood waters to TNWs, or to reduce the amount of pollutants or flood waters reaching a TNW? • Does the tributary, in combination with its adjacent wetlands (if any), provide habitat and lifecycle support functions for fish and other species, such as feeding, nesting, spawning, or rearing young for species that are present in the TNW? • Does the tributary, in combination with its adjacent wetlands (if any), have the capacity to transfer nutrients and organic carbon that support downstream foodwebs? • Does the tributary, in combination with its adjacent wetlands (if any), have other relationships to the physical, chemical, or biological integrity of the TNW? Note: the above list of considerations is not inclusive and other functions observed or known to occur should be documented below: 1. Significant nexus findings for non-RPW that has no adjacent wetlands and flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary itself, then go to Section III.D: 2. Significant nexus findings for non-RPW and its adjacent wetlands, where the non-RPW flows directly or indirectly into TNWs. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section I1I.D: Significant nexus findings for wetlands adjacent to an RPW but that do not directly abut the RPW. Explain findings of presence or absence of significant nexus below, based on the tributary in combination with all of its adjacent wetlands, then go to Section III.D: D.

This award was made on the condition that these funds be matched by $7,242 in additional non- federal funds raised by the Meadowview Biological Research Station specifically for this project. In the next few weeks, Ellen Lippincott will be generating a grant agreement and will contact you with any questions. In the meantime, please feel free to contact Ellen Lippincott at 202-857- 0166 with any questions or concerns. On behalf of the Board and staff of the National Fish and Wildlife Foundation, I wish you success with your project. 10.01.03 printed an recycled paper Program Manager, Native Plant Conservation Initiative 07/31/2008 13:38 FAX 2251464 BILTMORE GARDEN IA 003/003 REINTRODUCTION Endangered Pitcher Plant Reintroduced to North Carolina On June 15, 2007 Meadowview biologists, in conjunction with Biltmore staff and campers from Falling Creek Camp for Boys, reintroduced 300 federally endangered mountain sweet pitcher plant (Sarracenia jonesii Wherry) to a sphagnum seepage area on the Biltmore Estate. The project was funded by a grant from the National Fish and Wildlife Foundation and resulted in a 20% increase in number of sites for this endangered species. The project also included 50 controlled pollinations of mountain sweet pitcher plant by Meadowview for Green River Preserve in Cedar Mountain, NC. Green River Preserve constructed grow out beds and will raise mountain sweet pitcher plant on-site for planting in sphagnum bogs on their property. 01 0 40AI UNITMl *TArL•] \17141 A7. 1lI.R!<1n1(!. 1,L1\MI:TV I,i T+rr l'. n. l+T.l•.IRNI:?r of .,,I/ICYI.TY¢[ %IT[I? -r.?n» ?.?Tl?ra•?.- Il1'J.I•AI?fCw .4 Mountain sweet pitcher plant historically occurred in Buncombe County, NC on the Biltmore Estate (see herbarium specimens this page) but was apparently extirpated by dairy operations. The Biltmore Estate is still approximately the same size as when the herbarium specimens were collected be- tween 1895-1897 (see centerfold). Because the herbarium specimens clearly state the plants were collected at the Biltmore Estate, and we know the dimensions of the estate at the time of collection, we are confident that the plants are being introduced to their his- toric home. The description on one herbar- ium specimen of "near Biltmore" means near the Biltmore House proper. Meadow- view biologists and Biltmore staff examined wet depressions at the correct altitude speci- fied by the herbarium specimen (2250 ft.) but virtually all of these sites were drained or ditched long ago to improve pasture for the Biltmore Dairy. The historic loss of this endangered pitcher plant is a dramatic example of the 1 need for the mission and reintroduc- tion methods of Meadowview. If UNITED 9TATC8 NATIONAL I16rZpA ovm.
