Steel structures will frame the substation and provide support for switches, circuit breakers and transformers for operation of the facility. Mayor equipment could be oil or gas insulated. The exact type is not known as this time, but if oil - filled equipment is utilized, a Spill Prevention Control and Countermeasure Plan (SPCC) will be developed and implemented per EPA requirements. Siting /routing of the high -side 69 kV transmission line in currently in progress, but has not yet been finalized The substation pad will be graded relatively flat, slightly sloped for sheet -flow runoff By IEEE regulations (Institute of Electrical and Electronics Engineers), the station will be surfaced with a clean, washed, loose stone insulation. The substation will be secured and screened from view by an approximate 10 foot high masonry wall which will gated and locked at all times Upon completion, day -to -day operation of the substation should require minimal oversight and maintenance u ` O 9 . .

information that affects land use planning in survey areas They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas Sod surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment Soil surveys identify soil properties that are used in making various land use or land treatment decisions The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses The landowner or user is responsible for identifying and complying with existing laws and regulations Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases Examples include soil quality assessments (http / /www nres usda gov /wps /portal/ nres /main /sods /health /) and certain conservation and engineering applications For more detailed information, contact your local USDA Service Center (http // offices sc egov usda gov /locator /app ?agency =nres) or your NRCS State Soil Scientist (http / /www nres usda gov / wps / portal /nres /detail/soils /contactus /? cid= nres142p2_053951) Great differences in soil properties can occur within short distances Some soils are seasonally wet or subject to flooding Some are too unstable to be used as a foundation for buildings or roads Clayey or wet soils are poorly suited to use as septic tank absorption fields A high water table makes a soil poorly suited to basements or underground installations The National Cooperative Soil Survey is a point effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural

North Carolina 12 CuA— Cullowhee loam, 0 to 3 percent slopes, frequently flooded 12 WhB— Whiteoak fine sandy loam, 2 to 8 percent slopes 13 References 15 4 How Soil Surveys Are Made Soil surveys are made to provide information about the soils and miscellaneous areas in a specific area They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses Soil scientists observed the steepness, length, and shape of the slopes, the general pattern of drainage, the kinds of crops and native plants, and the kinds of bedrock They observed and described many soil profiles A soil profile is the sequence of natural layers, or horizons, in a soil The profile extends from the surface down into the unconsolidated material in which the sod formed or from the surface down to bedrock The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity Currently, soils are mapped according to the boundaries of mayor land resource areas (MLRAs) MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006) Soil survey areas typically consist of parts of one or more MLRA The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape Commonly, individual sods on the landscape merge into one another as their characteristics gradually change To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils They can observe only a limited number of sod profiles Nevertheless, these observations, supplemented by an understanding of the soil- vegetation- landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries Soil scientists recorded the characteristics of the soil profiles that they studied They noted soil color, texture, size and shape of sod aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units) Taxonomic classes are concepts Each taxonomic class has a set of soil characteristics with precisely defined limits The classes are used as a basis for comparison to classify soils systematically Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of sod properties and the arrangement of horizons within the profile After the soil scientists classified and named the soils in the survey area, they compared the 5 Custom Soil Resource Report individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research The objective of soil mapping is not to delineate pure map unit components, the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements Each map unit is defined by a unique combination of soil components and /or miscellaneous areas in predictable proportions Some components may be highly contrasting to the other components of the map unit The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans If intensive use of small areas is planned, onsite investigation is needed to define and locate the sods and miscellaneous areas Soil scientists make many field observations in the process of producing a soil map The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist Observations are made to test and refine the soil - landscape model and predictions and to verify the classification of the soils at specific locations Once the soil- landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components Properties of each soil typically vary from one point to another across the landscape Observations for map unit components are aggregated to develop ranges of characteristics for the components The aggregated values are presented Direct measurements do not exist for every property presented for every map unit component Values for some properties are estimated from combinations of other properties While a soil survey is in progress, samples of some of the sods in the area generally are collected for laboratory analyses and for engineering tests Soil scientists interpret the data from these analyses and tests as well as the field- observed characteristics and the soil properties to determine the expected behavior of the soils under different uses Interpretations for all of the sods are field tested through observation of the soils in different uses and under different levels of management Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs Data are assembled from other sources, such as research information, production records, and field experience of specialists For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity Soil conditions are predictable over long periods of time, but they are not predictable from year to year For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the sod on a specific date After soil scientists located and

The purpose of this investigation was to document the physical and biological features of the lot, including surface water, wetlands, vegetation types, and the presence of any protected species. The approximately one -acre lot and an adjacent area to the south of the lot, which is approximately 0.5 acres, are located in the USGS Valle Crucis, NC 7.5 minute topographic map. The proposed lot is located in the community of Norwood Hollow of the City of Sugar Mountain in Avery County, NC, at an elevation of approximately 3900 feet mean - sea -level (Figure 2). METHODS The entire site was inventoried, including the approximately 1 -acre lot and an approximately 0.5- acre area immediately south of the property. The adjoining property on the south may be necessary for folding in lines from an existing electric line. Surface waters were evaluated using the criteria of the US Army Corps of Engineers Jurisdictional Determination Form, Instructional Guidebook (US Army Corps of Engineers and US Environmental Protection Agency 2007); wetlands were evaluated using the US Army Corps of Engineers Wetlands Delineation Manual (US Army Corps of Engineers 1987). In addition, the site was searched for potential habitat for species tracked by the North Carolina Natural Heritage Program (NHP) or listed by the United States Fish and Wildlife Service (USFWS). No aquatic inventories were performed as part of this investigation. The Asheville Office of the US Army Corps of Engineers reviewed our findings in the field on June 23, 2010, and the following results reflect their recommendation on wetland and waters boundaries and determinations. RESULTS AND DISCUSSION Waters and Wetlands Several water features were documented on the lot, including two linear wetlands, two relatively permanent waters, and three non - jurisdictional conveyances (Figure 3). Both wetlands are jurisdictional. Wetland -1 (W -1) is a manmade ditch that is a linear wetland, which originates at a springhead near the southern edge of the property and extends for approximately 115 feet before reaching the property boundary. This wetland extends upstream (south) into the property adjoining the lot, but is not contiguous and breaks near the property boundary. Twenty feet of W -1 is located in an existing culvert; the culvert and the lack of grade of this manmade ditch probably caused the development of the wetland here. For discussion, W -1 is separated into two sections W -1 a and W -1 b. W -1 a is closest to the spring head and extends 69 feet before reaching the inlet of the culvert (Figure 4). The width of W -1a averages 3.8 feet and has vegetation consisting of purplestem aster (Symphyotrichum puniceum), curly dock (Rumex crispus), orchard grass (Dactylis glomerata), sedge (Carex spp.), spikerush (Eleocharis spp.), touch -me -not (Impatiens spp.), and primrose - willow (Ludwigia spp.). In close to 90- degree weather with no rain the previous day, 3 inches of inundated water was present. W -1 b (Figure 5), 27.0 feet in length, has an average width of 4.0 feet, was inundated with 1.0 inch of water; it is vegetated with orchard grass, creeping buttercup (Ranunculus repens), arrowleaf tearthumb z (Polygonum sagittatum), primrose - willow, and spikerush. The total area of linear W -1 is 445.9 feet2, with 78.0 feet2 of the total previously impacted with the culvert. Wetland -2 (W -2) develops from a springhead located in the middle of the property (Figure 3 and 6). At and around the springhead the wetland takes on a polygon shape (W -2a), before reaching a channel, probably constructed during previous development, then continues for 90 feet as a linear wetland (W -2b) (Figure 7). The average width of W -2b is 2.3 feet for an area of 207 feet2; the area of the polygon feature of W -2a is 227 feet2, for a total area of 434 feet2. The vegetation includes woodland bulrush (Scirpus expansus), common rush (Juncus effusus), purplestem aster, black elderberry (Sambucus nigra), touch -me -not, common boneset (Eupatorium perfoliatum), black willow (Salix nigra), orchard grass, and mannagrass (Glyceria spp.). Inundation averaged 1.3 inches throughout the feature of W -2b. Soil samples confirm the presence of hydric soils in the wetland area. Wetland and waters characteristics are summarized in Table 1. One area near the entrance, where the exotic yellow flag iris (Iris pseudacorus) is planted, was investigated as a wetland, but, while hydric soils and hydrophytic vegetation are present, no wetlands hydrology is. Wetland data forms are provided in Appendix Tables 3, 4, and 5. Two class C streams (NCDENR 2009) exist on the proposed Sugar Mountain Substation lot (Figure 3). One is named Flattop Creek and the other is unnamed. Both streams are jurisdictional (relatively permanent waters). The unnamed stream (Stream -1) develops from W- 2. Flattop Creek flows through the northwest corner of the property for approximately 89 feet. The substrate of Flattop Creek consists of cobble, gravel and sand with a full bank width of 8.0 feet (Figure 8). The maximum water depth is 4.0 inches and supports caddis flies, mayflies and fishes. Stream -1 (S -1), which flows from W -2 to Flattop Creek (Figure 9), has a substrate of sand, silt, gravel, and cobble and supports a population of caddis flies and mayflies. The average width of S -1 is 3.6 feet, the length is approximately 25.0 feet to the property boundary and it had a maximum water depth of 2.0 inches. Three non jurisdictional conveyances (NJC) were identified on the property (Figure 3). W -1 stops at the property boundary at a culvert inlet; the outlet of the culvert empties into a NJC (approximately 90 feet long), which leads to S -1. The gravel parking area is separated from the early succession community by a drainage or NJC. The last NJC originates at the springhead of W -2, and transports storm water to Flattop Creek. The US Army Corps of Engineers supports the determination of the NJC. Characteristics of the waters are provided in Table 2. Rare Species Habitats Approximately one -third of the site is being use as a waste and recycling center and the remainder is largely an early succession community. The eastern portion of the site contains a gravel parking lot, a waste and recycling facility, and a landscaped area (Figure 10). The terraced and landscaped areas contain plantings of eastern white pine (Pines strobus), the exotic yellow flag iris (Iris pseudacorus), and various grasses and herbs and this area contains the waste and recycling containers. The remainder of the lot is unimproved and is largely an early succession plant community, with small wetland plant communities and a narrow band of riparian forest along Flattop Creek. Based on soil samples at the site, most of the site appears to have been filled and graded. Two linear wetland areas are formed by springs, one originating 3 on the lot and the other on the adjacent southern property. Hydrophytic plant species were documented in the wetland areas including woodland bulrush, arrowleaf tearthumb, black elderberry, touch -me -not, creeping buttercup, common rush, black willow, orchard grass, mannagrass, shallow sedge, common boneset (Eupatorium perfoliatum), and several Cyperus species, among others. In the early succession community, woody vegetation is sparse, consisting of scattered black willow (Salix nigra), sapling stage red maple (Acer rubrum), as well as Frasier fir (Abies frasen) and mountain laurel (Kalmia latifolia). The latter two may be remnants from a prior nursery operation. Herbaceous plants are abundant in the early succession community and include devil's darning needles (Clematis virginiana), blackberry (Rubus spp.), common cinquefoil (Potentilla simplex), curly dock (Rumex crispus), purplestem aster, and orchard grass (Dactylis glomerata), among many others (Appendix Table 1). A riparian community exists in a narrow band adjacent to the southeastern bank of Flattop Creek. Canopy dominants include sweet birch (Betula lenta), yellow birch (Betula alleghaniensis), yellow buckeye (Aesculus flava) and a non - native beech species (Fagus spp.). The understory is dominated by highland doghobble (Leucothoe fontanesiana) and great laurel (Rhododendron maximum). The herbaceous layer includes intermediate wood fern (Dryopteris intermedia), bay forget -me -not (Myosotis laxa), touch -me -not (Impatiens spp.) and rattlesnake root (Prenanthes spp.). A list of plant taxa observed during this investigation is provided in Appendix Table 1. Twenty -four rare or uncommon natural plant communities, tracked by the NHP, exist in Avery County, NC (see Appendix Table 2); these communities result from the varied elevations, aspects, moisture, and substrate of this mountain county. The varied habitats contribute to the great species diversity and number of "rare" species of the area. The NHP tracks 17 invertebrates, 26 non - vascular plants, 66 vascular plants, and 34 vertebrates in Avery County (Appendix Table 2). These species are tracked because they are federally listed or are "significantly rare" or of "special concern" due to their relative rarity in NC. Similarly, the US Fish and Wildlife Service (FWS) list 16 vertebrates (3 listed as endangered or threatened), 4 invertebrates (1 listed as endangered), 15 vascular plants (4 listed as endangered or threatened), and 4 non - vascular plants (1 listed as endangered) from Avery County (Table 2). The species listed as endangered or threatened are (US Fish and Wildlife Service 2010): Spreading avens- found on high - elevation cliffs, outcrops, and steep slopes, which are exposed to full sun; also in thin, gravelly soils of grassy balds near summit outcrops. Roan mountain bluets- found in crevices of rock outcrops at the summits of high elevation (4200 -6300 feet) peaks of the southern Blue Ridge Mountains; also in thin, gravelly soils of grassy balds near summit outcrops. Heller's blazing star -found on high elevation ledges of rock outcrops and cliffs in shallow acid soils in full sun. Rock gnome lichen -found on rocks in areas of high humidity either at high elevations (usually vertical cliff faces) or on boulders and large rock outcrops in deep river gorges at lower elevations. Spruce -fir moss spider -found in Fraser fir and red spruce forest communities of the highest elevations of the southern Appalachian Mountains. 4 Virginia big -eared bat -in the eastern U.S., with rare exception, it has been reported only from caves during summer and winter. Northern flying squirrel- found in high elevations in forests dominated by conifers but can also be relatively abundant in deciduous and mixed coniferous /deciduous forests. Blue Ridge goldenrod -found on cliffs, ledges, balds, and rock outcrops of higher mountain peaks above 4600 feet elevation that are exposed to full sun. None of the habitats for the above federally listed species occur at the proposed substation site. Likewise, none of the rare or uncommon natural plant communities tracked by the NHP (Appendix Table 2) occur at the site. The relatively narrow riparian community on the site adjacent to Flattop Creek and Flattop Creek aquatic habitat are the only relatively undisturbed habitats on the site. Flattop Creek (Figure 8) could contain aquatic invertebrates tracked by the NCNHP, but aquatic inventories were beyond the scope of this investigation. The NHP's database indicates that northern shorthusk (Brachyelytrum aristosum) and Canada lily (Lilium canadense ssp. editorum) have been reported from a broad area of the Sugar Mountain Substation lot; these species are listed by NHP as significantly rare and on the periphery of their range. Sphagnum (Sphagnum squarrosum) is shown on the database but not listed on the current Avery County list (Appendix Table 2). A thorough search of the site revealed no federally listed species or species tracked by the NHP. Sources North Carolina Department of Environmental and Natural Resources. 2009.

Program tally the elements of natural diversity (rare plants and animals, rare and exemplary natural communities, and special animal habitats) known to occur in all North Carolina counties and USGS 7 5- minute quadrangles The information on which these lists is based comes from a variety of sources, including field surveys, museums, herbaria, scientific literature, and personal communications These lists are dynamic, with new records continually being added and old records being revised as new information is received As a result, a list cannot be considered a definitive record of the elements of natural diversity present in a given county or quad and should not be used as a substitute for field surveys When this information is used in any document, we request that the date this list was compiled be given and that the NC Natural Heritage Program be credited STATE STATUS CODE ]STATUS CODE STATUS E Endangered SR Significantly Rare T Threatened EX (Extirpated SC Special Concern

Solutions, LLC 10101 Claude Freeman Dr State 100 -W Charlotte, North Carolina 28262 4/15/11 RE Cultural Resources Literature Review and Windshield Reconnaissance for Sugar Mountain Transmission Line Siting, Avery County, North Caiohna Dear Mi Jenkins, In March 2011, Brockington and Associates, Inc contracted with Pike Energy Solutions, LLC to conduct both a cultural resources literature review and a windshield reconnaissance for the proposed Sugar Mountain Transmission Line in Avery County, North Carolina The research results outlined in this letter report provide information for planning purposes only and are not meant to serve as compliance with Section 106 of the National Historic Preservation Act or other state and /or federal legislation Literature Review, Architecture On March 16, 2011 we conducted a hterature review for all previously recorded arcltectural resources located within the study area boundary This research was conducted at the western office of the North Carohna Office of Survey and Planning (OSP) in Asheville The OSP systematically plots all architectural properties recorded through county surveys or environmental review reports on USGS 7 5 minute topographical maps These maps are updated several tunes each year and delineate recorded properties into five categories National Register, Study List, Determination of Eligibility, Locally Designated and Survey Properties The Sugar Mountain Transmission Line study area encompasses appioxunately 6 square miles within Avery County, North Carohna There are a total of seven (7) previously recorded above- ground resources (properties or districts) recorded within this study area The OSP classifies the resources as follows three (3) are on the Study List and four (4) are Survey Properties One of the resources currently on the Study List, the Banner Elk School (AV100), is currently being nominated to the National Register of Hrstotic Places (NRHP) There are no other NRHP listed properties within the study area Where possible, eligible or potentially eligible NRHP properties should be avoided and visual effects evaluated dutmg project planning Literature Review, Archaeology Recorded archaeological sites in North Carohna are plotted by hand on USGS topographic maps As part of our standard archaeological site search, we copied the relevant maps from the western office of the Office of State Archaeology (OSA) in Asheville, as well as the corresponding site forms We then digitized the sites that are located within the study area for this project to create a cultural resources GIS data layer We also searched the state archaeological site list to ascertain if a determination of eligibility has been made for any of the sites within the study area Atlanta • Charleston • Savannah • Jacksonville • Pensacola • Elizabethtown • Eddyvdle www brockmgton org For the Sugai Mountain Transmission Line study area, eight (8) previously iecoided archaeological sites fall within the study area boundary (Figuie 1) Of die eight (8) previously recorded sites, four (4) were deterrnmed ineligible for the NRHP (31AV104, 31AV105, 31AV106, 31AV108), and one (1) does not have a site form on file at the OSP office (31AV107) We were able to determine the location of site 31AV107 without a site form because it was plotted on the site maps for sites 31AV104- 31AV108 These five reports with consecutive site numbers were all recorded as pact of an environmental review compliance survey mandated by the construction of a Lowe's home unpiovement ietail stole The surveyor that recorded these five sites in 2004 noted that they would likely be destroyed by the construction of die Lowe's, and after plotting the sites on an aerial map, we concur that they were probably destroyed during construction The remaining three (3) previously recorded archaeological sites (31AV17, 31AV18, 31AV20) were recorded in 1977 No foimal assessment of theft eligibility was made on the 1977 site forms, but the surveyor did evaluate their research potential, noting that sites 31AV17 and 31AV20 likely had low research potential while site 31AV18 likely had high research potential The significance of archaeological sites for listing on the NRHP is evaluated based on their research potential or their ability to provide information about history or pre - history under Criterion D, so site 31AV18 may have been eligible for listing on the NRHP The surveyor also noted that these sites would likely be destroyed by the construction of the sewer line that mandated the survey Determining the status of these sites is complicated by the poor quality of the 1977 site maps, which only indicate appioximate locations, and by the fact that the path of the underground sewer line that would have impacted the sites is not visible on aerial images As site 31AV18 may be extant and may be eligible for listing on the NRHP, it should be avoided for physical impacts during project planning whenever possible Windshield Reconnaissance From March 16 through 18, 2011, the project histouan conducted a windshield reconnaissance of the Sugar Mountain Transmission Line study area As outlined in National Register Bulletin #24, a windshield reconnaissance -level survey is useful in asceitain ng "a general picture of the chstilbution of different types and styles [of architectural resources], and of the character of different neighborhoods" (Packer 1985 35 -36) Windshield surveys are also useful for makmg prelinnnary assessments of eligibility based on the architectural integrity of properties, but not in asceitammg the historical associations a property might possess The Sugar Mountain Transmission Line study area is home to the town of Banner Elk, North Carohma The area surrounding Banner Elk was once largely agricultural and rural, but a great deal of development associated with vacation homes and tourism has changed the area substantially It now features a mixture of historic and non - historic residences and commercial buildings characterized by a variety of architectural types and styles The Sugar Mountain Transmission Line reconnaissance consisted of a vehicular inspection of architectural resources visible from all publicly accessible roads within the 6 square mile study area It is important to note that topographic and aerial maps often indicate properties located along private roads as well as abandoned and existing field roads If a previously recorded property is found to be inaccessible, we reference cuuent aerials to determine whether a building is extant The purpose of our windshield reconnaissance was to 1 Evaluate all previously recorded architectural resources (if any), 2 Locate architectural resources not previously recorded and that appear to meet the minimum fifty year age requirement for the NRHP, and 3 Identify potentially eligible NRHP properties There were originally seven (7) previously recorded architectural resources within the study area During the windsh eld reconnaissance, we evaluated the (7) previously recorded resources for NRHP eligibility Four (4) of the previously recorded resources (AV117, AV118, AV119, AV131) are classified as Survey Properties by the OSP It is our opinion that Resource AV131, The Grandfather Home for Children, is potentially eligible for fisting on the NRHP, while the remaining duce resources are not eligible for listing on the NRHP The remaining three (3) previously recorded arcltectural resources (AV100, AV101, AV110) were placed on the OSP Study List to determine ffienr eligibility for listing on the NRHP It is our opinion that Resource AV100, the Banner Elk School, is eligible for listing on the NRHP and Resources AV101 and AV110 are potentially eligible for listing on the NRHP Please reference the table below for the status of the previously recorded resources Resource Resource Name OSP Classification Brockington Evaluation ID AV117 Lewis B Banner House Survey Property Not

During the course of the windshield reconnaissance, we identified 2 above - ground resources that appear to retain sufficient architectural integrity to be considered potentially eligible for the NRHP Resource 1 (Figures 2 and 3) is a 1920 1 5 -story Central Hall I -House located at 155 Banner Road Resource 2 (Figures 4 and 5) is a 1 5 -story cross- gabled stone house built in 1949 and located at 1010 Shawneehaw Avenue As both of these resources are potentially eligible for the NRHP, they should be avoided and visual effects evaluated during project planning whenever possible We observed numerous other properties drat appear to be 50 years old (thus, meeting the rnnnnnnal standard for NRHP eligibility consideration) distributed throughout the study area, these aie properties that would be tecolded by an aicbitectuial historian during a standard Section 106 survey Due to significant alterations or modifications, these properties appear to have lost their architectural integrity and may not meet the criteria of eligibility for hsting on the NRHP under Criterion C However, these properties might possess historical significance which could only be deteimined through archival research such as would be required for a Section 106 cultural resources survey We did not attempt to plot each of these resources in our GIS dataset Where possible, those properties considered potentially eligible for the NRHP should be avoided and visual effects considered during project planning The Comprehensive Resource Map (Figure 1) provided below details the findings from both the hteiatuie review and windshield reconnaissance The projection used to develop the map and shapefiles was NAD 1927 UTM Zone 17 Should you have any questions regarding the GIS data or require any
