Roadway Design, Roadside Environmental Unit, and Division 14 To avoid or reduce impacts to the federally protected Indiana Bat, NCDOT will: • Leave damaged and dead trees as long as they do not create a safety hazard. • Avoid, to the extent practicable, stream degradation by channelization, siltation, or other pollution to protect macroinvertebrate food sources for bats. Environmental Assessment May 2004 page 2 of 2 Environmental Assessment Prepazed by the Project Development and Environmental Analysis Branch of the North Cazolina Department of Transportation In Consultation with the Federal Highway Administration SUMMARY SR 1323 (Riverview Street) and NC 28 (Bryson City Road) Improvements From SR 1729 (Depot Street Extension) to SR 1378 (Bennett Road) 1. Type of Action This is a Federal Highway Administration (FHWA) Administrative Action, Environmental Assessment (EA). 2. Description of Action The North Carolina Department of Transportation (NCDOT) proposes to improve SR 1323 (Riverview Street) and NC 28 (Bryson City Road) from SR 1729 (Depot Street Extension) to SR 1378 (Bennett Road). The proposed action extends northwazd from the Town of Franklin into Macon County. Figure 1 shows the location of the project. The purpose of this project is to correct existing roadway deficiencies by improving the vertical and horizontal alignment and widening the travel lanes and shoulders. The total length of the project is approximately 3.6 miles. Figure 2 shows an aerial view of the project area. The improvements to SR 1323 (Riverview Street) and NC 28 (Bryson City Road) aze both state and federally funded. Project Number R-2408 is included in NCDOT's latest approved Transportation Improvement Program (TIP). The project is divided into sections A and B for right of way acquisition and construction in the 2004-2010 TIP. Section A (state funded) begins at SR 1729 (Depot Street Extension) and ends neaz the junction of NC 28. Section B (federally funded) begins neaz the junction of NC 28 and continues north to SR 1378 (Bennett Road). Right of way and construction for Section A aze scheduled in state fiscal years 2005 and 2006, respectively. Right of way and construction for Section B are scheduled for federal fiscal years 2006 and 2008, respectively. 3. Alternatives Considered Two alternatives were considered for the proposed project. The alternatives include the No-Build Alternative, and Build Alternative. The No-Build Alternative does not correct existing roadway deficiencies along SR 1323 and NC 28. Since the No-Build Alternative does not address the purpose and need, it is not recommended. The Build Alternative contains three roadway improvement options identified as Alternates 1, 2, and 3. The three alternates generally follow the existing alignment of SR 1323 and NC 28 to minimize impacts to the human and natural environments. All alternates widen the travel lanes and shoulders. Alternates 1 and 3 improve the horizontal and vertical alignment while Alternate 2 maintains the existing alignment of the road. All three alternates begin at the intersection of SR 1323 (Riverview Street) and SR 1729 (Depot Street Extension) and continue northward along SR 1323 (Riverview Street) to the junction of NC 28. The proposed improvements then continue along NC 28 to the northern project terminus at SR 1378 (Bennett Road). The project ends before crossing the Little Tennessee River on NC 28. The proposed typical section of Alternates 1, 2, and 3 include 12-foot travel lanes and 8- foot shoulders. Shoulders include four feet of pavement to accommodate bicycles. The typical section is shown by Figure 4. 4. NCDOT Recommended Alternative The NCDOT is recommending Alternate 3 for the improvements proposed in this Environmental Assessment. Alternate 3 provides the best balance between roadway improvements and social and environmental impacts throughout the length of the project. The total estimated cost of the project for Alternate 3 is $9,456,000 consisting of $5,300,000 for construction and $4,156,000 for right of way acquisition. 5. Coordination The following federal, state, and local agencies were consulted during the preparation of this Environmental Assessment: US Army Corps of Engineers -Asheville US Army Corps of Engineers -Wilmington US Fish and Wildlife Service -Asheville US Environmental Protection Agency -Atlanta NC Department of Administration, NC State Clearinghouse NC Department of Public Instruction NC Department of Cultural Resources - SHPO NC Department of Environment and Natural Resources Division of Water Quality Division of Soil and Water Conservation Division of Forest Resources Division of Land Resources Division of Parks and Recreation NC Wildlife Resources Commission Macon County Town of Franklin r 11 6.

Actions Required By Otter Agencies Constructing the proposed action will result in impacts to jurisdictional surface waters. In accordance with Section 404 of the Clean Water Act (33 U.S.C. 1344), a Nationwide Permit is anticipated from the US Army Corps of Engineers. NCDOT will implement erosion and sedimentation control measures, as specified by NCDOT's "Best Management Practices for Protection of Surface Waters". The proposed project will also require a Section 401 Water Quality General Certification from the North Carolina Department of Environment and Natural Resources, Division of Water Quality. Section 401 of the Clean Water Act requires that the state issue or deny water certification for any federally permitted or licensed activity that may result in a discharge to Waters of the United States. Section 401 Certification allows surface waters to be temporarily impacted for the duration of the construction or other land manipulation. The proposed project is located in the Tennessee River Watershed. A permit pursuant to Section 26a of the TVA Act, is required for all obstructions involving streams or floodplains in the Tennessee River drainage basin. 8. Other Major Actions The Depot Street Extension (TIP Project Number U-2929) is currently under construction at the southern terminus of the proposed action. The Depot Street Extension (SR 1729) is a two-lane roadway on new location connecting to SR 1323 (Riverview Street). 9.

PURPOSE AND NEED A. General Description of Project The North Carolina Department of Transportation (NCDOT) proposes to improve SR 1323 (Riverview Street) and NC 28 (Bryson City Road) from SR 1729 (Depot Street Extension) to SR 1378 (Bennett Road). The proposed action extends northwazd from the Town of Franklin into Macon County. The southern terminus of the project is located just west of the Little Tennessee River. Figure 1 shows the location of the project. The total length of the project is approximately 3.5 miles. Figure 2 shows an aerial view of the project azea. B. Purpose and Need The purpose of this project is to correct existing roadway deficiencies along SR 1323 and NC 28. The road has substandard geometrics and an inadequate typical section. Travel lanes and shoulders aze narrow and the vertical and horizontal alignments aze deficient according to the current NCDOT design standazds. Because of the mountainous terrain, the road has steep drop-offs and large inclines on opposite sides of the road. This makes it difficult to travel along this road with narrow lanes and sharp curves that limit a driver's sight distance. The corridor is also a preferred route for tractor trailer trucks. Table 2 shows the existing deficient design speed of horizontal and vertical curves along SR 1323 and NC 28 in the project azea. Horizontal curves aze either to the left or right while vertical curves aze either uphill or downhill. The approximate locations of the deficient curves are shown in Figure 3. C. Project Status The improvements to SR 1323 (Riverview Street) and NC 28 aze both state and federally funded. Project Number R-2408 is included in NCDOT's latest approved Transportation Improvement Program (TIP). The project is divided into sections A and B for right of way acquisition and construction in the 2004-2010 TIP. Section A (state funded) begins at SR 1729 (Depot Street Extension) and ends near the junction of NC 28. Section B (federally funded) begins near the junction of NC 28 and continues north to SR 1378 (Bennett Road). Right of way and construction for Section A aze scheduled in state fiscal years 2005 and 2006, respectively. Right of way and construction for Section B are scheduled for federal fiscal years 2006 and 2008, respectively.

EXISTING CONDITIONS The proposed project is located in Macon County in southwestern North Carolina. The project follows existing SR 1323 and NC 28 from SR 1729 (Depot Street Extension) to SR 1378 (Bennett Road). NC 28 is identified as a Major Collector in the Functional Classification System for highways and roads. A. Length of Roadway Section Studied The total length of the project is approximately 3.$ miles. The Federal Highway Administration (FHWA) has determined that the project, as currently proposed, connects logical termini. It is of sufficient length to address environmental matters on a broad scope, has independent utility and significance, and is a usable and reasonable expenditure even if no additional transportation improvements are made in the area. B. Existing Typical Section SR 1323 and NC 28 are currently two-lane roads with travel lane widths of 11 feet and variable width shoulders. C. Speed Limits Speed limits vary throughout the project area. At the southern terminus of the project, SR 1323 currently has a posted speed limit of 3$ miles per hour. The speed limit increases to 45 miles per hour beyond the Franklin corporate limit and continues to just north of Windy Gap Road on NC 28. From just north of Windy Gap Road to the northern project terminus, the speed limit increases to 55 miles per hour. D. Sidewalks No sidewalks aze currently in place along SR 1323 and NC 28. E. Right of Way The existing right of way width along SR 1323 is approximately 30 feet. NC 28 has an existing right of way width of approximately 60 feet. F. Railroad Crossings There aze no railroad crossings along SR 1323 and NC 28 in the project azea. G. Intersecting Roads All roadways in the project azea have at-grade intersections with SR 1323 and NC 28. There aze no traffic signals in the project azea. H. Degree of Roadside Interference Land use in the project azea is a mixture of residential, commercial, and agricultural. Residential and commercial development is scattered throughout the project. Agricultural land uses aze generally located north of the intersection of SR 1323 and NC 28. I. Structures There are no existing bridges within the project area. A 6-foot wide by 6-foot high box culvert is located below NC 28 at Rocky Branch. J. Utilities All major utilities aze located in the project azea. Water lines extend northward along SR 1323 almost to the intersection with NC 28. SR 1323 crosses a sewer line near the southern terminus of the project. K. Bicycle Routes There is one bicycle route in the project azea. Bicycle Route 30 (Nikwasi Route) follows NC 28 between Windy Gap Road and Airport Road, for a distance of approximately 0.5 miles. The recommended typical section includes afour-foot paved shoulder to accommodate bicycles throughout the project area. L. School Bus Data Within the project azea, Macon County school system buses make eight trips per day along SR 1323 and NC 28. M. Navigable Waters There are no navigable waters in the project azea. N. Greenways There is one existing greenway in the project azea. The Suli Mazsh Greenway begins approximately 0.5 mile north of the southern project terminus. An unpaved pazking azea for greenway users is located adjacent to SR 1323 within the Franklin corporate limits. The greenway extends along the mazsh southwazd to Main Street. The greenway does not cross SR 1323. At the closest point, the greenway is located approximately 100 feet from SR 1323. The county plans to extend the greenway fiuther south into Franklin, away from the project azea. III. ALTERNATIVES CONSIDERED A. Alternatives Considered For Detailed Study The alternatives considered in this Environmental Assessment include the No-Build Alternative and the Build Alternative. The Build Alternative consists of three options for improving SR 1323 and NC 28. The improvement options aze identified as Alternates 1, 2, and 3. 1. No-Build Alternative The No-Build Alternative offers no improvements to the project azea. The No- Build Alternative assumes all other projects currently planned or programmed in the TIP will be constructed in the area as proposed. Continued roadway maintenance and minor improvements along SR 1323 and NC 28 are a part of this concept. The No-Build Alternative does not correct existing roadway deficiencies along SR 1323 and NC 28. Since the No-Build Alternative does not address the purpose and need of the proposed action, it is not recommended. 2. Build Alternative The Build Alternative consists of three options for improving SR 1323 and NC 28. These improvement options aze identified as Alternates 1, 2, and 3. All three alternates begin along SR 1323 at SR 1729 (Depot Street Extension) and end along NC 28 near the intersection of SR 1378 (Bennett Road), before crossing the Little Tennessee River. All three alternates maintain the existing two-lanes of traffic. The total length of Alternates 1, 2, and 3 is approximately 3.5 miles. The proposed typical section for all three alternates is shown by Figure 4. a. Alternate 1 Improvements for Alternate 1 include 12-foot travel lanes, 8-foot shoulders (4-foot paved for bicycle accommodations), and vertical and horizontal alignment improvements. This alternate upgrades the existing horizontal and vertical alignments to meet the minimum American Association of State Highway and Transportation Officials (AASHTO) standazds for this type of facility. 4 b. Alternate 2 Alternate 2 maintains the existing horizontal and vertical alignments along SR 1323 and NC 28 with minimal widening and resurfacing. This alternate provides two 12-foot travel lanes and 8-foot shoulders (4-foot paved for bicycles). c. Alternate 3 (Recommended) Improvements for Alternate 3 include 12-foot travel lanes, 8-foot shoulders (4-foot paved for bicycle accommodations), and vertical and horizontal alignment improvements. This alternate is a combination of Alternates 1 and 2. Alternate 3 minimizes social and environmental impacts by incorporating retaining walls and expressway gutter into the design. This alternate is recommended because it improves existing substandazd conditions and avoids and minimizes human and natural impacts and costs associated with a full upgrade. d. TraffSc Capacity Capacity is defined as the maximum number of vehicles that can be accommodated in reasonable safety along a roadway within a specific time period. When traffic volumes approach or exceed the capacity of the roadway, operating levels of service aze diminished and congestion results. Simply defined, level of service is a qualitative measure that describes operational conditions of a traffic stream along a roadway or at an intersection of two roadways. Six levels of service aze defined from A to F, with Level of Service A representing the best and Level of Service F the worst operational conditions. Estimated Average Daily Traffic (ADT) volumes were developed for the proposed SR 1323 and NC 28 improvements for years 2002 and 2025. The traffic volumes are shown in Figures 5 and 6, respectively. 1). Existing Conditions On SR 1323, the average daily traffic (ADT) volume for the yeaz 2002 is 5,200 vehicles per day between the Depot Street Extension and NC 28. This traffic volume corresponds to Level of Service C conditions as shown by Figure 6. Average daily traffic (ADT) volumes along NC 28 for the yeaz 2002 increases to 8,800 vehicles per day just north of the intersection of SR 1323. This traffic volume results in Level of Service D conditions as shown by Figure 7. 2). Year 2025 Conditions Yeaz 2025 conditions aze for both build and no build conditions, since the proposed improvement retains one travel lane in each direction along SR 1323 and NC 28. By the yeaz 2025, the average daily traffic volume on SR 1323 is expected to increase to 9,100 vehicles per day, resulting in Level of Service D conditions. Yeaz 2025 average daily traffic volumes on NC 28 is expected to increase to 15,300 vehicles per day, resulting in Level of Service D conditions. Yeaz 20251evels of service are shown by Figure 7. 5 e. Horizontal and Vertical Curvature Comparison The three alternates under consideration have different curve design speeds within the project azea. Design speeds of horizontal curves (curves to the left or right) aze shown by Table 3, while vertical curve (curves up or down) design speeds aze shown by Table 4. Alternate 2 does not improve the design speed of the horizontal and vertical curves along the length of the project. Alternates 1 and 3 improve the design speed of the horizontal and vertical curves as indicated by the tables. The approximate location and design speed of the proposed curve improvements aze shown by Figure 8.

Typical Section Description A two-lane typical section with shoulders is being proposed for the improvements along SR 1323 and NC 28. The typical section for the recommended improvement option (Alternate 3) is shown in Figure 4. The typical section for Alternate 3 includes 12-foot travel lanes and 8-foot shoulders (4-foot paved for bicycles). C. Right of Way The proposed right of way width varies throughout the length of the project and is dependent on the terrain, slope of the cut and fill section, and typical section details. The travel lanes and shoulders of Alternates 1, 2, and 3 require a minimum right of way width of 40 feet. The typical section for Alternates 1, 2, and 3 is shown by Figure 4. The overall proposed right of way is approximately 100 feet with additional construction included in easements along SR 1323 and NC 28. D. Access Control No control of access will be used for the proposed improvements along SR 1323 and NC 28. E. Intersection Treatment and Type of Control At-grade intersections will be used throughout the proposed project. All intersections will remain unsignalized. Lane configurations of major intersections along SR 1323 and NC 28 are shown by Figure 9. All intersections will be stop sign controlled. F. Speed Limit and Design Speed The current speed limits along SR 1323 and NC 28 will likely be maintained with the proposed improvements. At the southern terminus of the project, SR 1323 currently has a posted speed limit of 35 miles per hour within the Franklin corporate limits. The speed limit increases to 45 miles per hour north of Franklin and continues to just north of Windy Gap Road on NC 28. From just north of Windy Gap Road to the northern project terminus, the speed limit increases to 55 miles per hour. The design speed is typically 5 miles per hour higher than the posted speed limit. Alternate 3 will have design exceptions. G. Maintenance of Traffic All traffic control devices used on this project will conform to the most current Manual of Uniform Traffic Control Devices (MUTCD). H. Noise Barriers No noise barriers are proposed as part of this project. I. Sidewalks No sidewalks aze proposed for the SR 1323 and NC 28 improvement project. A sidewalk was not included in the adjacent Depot Street Extension project (TIP Project Number U-2929). J. Bicycle Accommodations Special accommodations for bicycles aze included in the proposed action. All improvement options include 4-foot paved shoulders to accommodate bicycles. The four- foot paved shoulder is consistent with the department's paved shoulder policy for two-lane roadways with over 8,000 average daily traffic in the design yeaz. K. Structures There aze no bridges located within the project limits. A 6-foot wide by 6-foot high box culvert is located below NC 28 at Rocky Branch. The NCDOT Hydraulics Unit recommends replacing the existing culvert with a two barrel seven feet wide by seven feet high reinforced concrete box culvert. Due to the anticipated fill height, phased construction may not be practical. An off-site detour with a total length of 1.4 miles is available during construction along SR 1381, SR 1382, and SR 1434 as shown by Figure 1. L. Greenways There is one existing greenway in the project azea. The Suli Mazsh Greenway begins approximately 0.5 miles north of the southern project terminus near Lake Emory. An unpaved parking area for greenway users is located adjacent to SR 1323 within the Franklin corporate limits. The greenway extends along the mazsh southwazd to Main Street but does not cross SR 1323. At the closest point, the greenway is located approximately 100 feet from SR 1323. M. Right of Way Cost Right of way costs aze based on the preliminazy design of the three alternates studied in detail. Right of way costs include: residential and business relocation, land and damage, utilities, and acquisitions. The estimated right of way cost for Alternate 1 is $5,085,000, Alternate 2 is $5,085,000, and Alternate 3 is $4,156,000. N. Construction Cost Estimated construction costs aze based on preliminary design of the three alternates. The construction cost estimate includes items such as clearing and grubbing, earthwork, drainage, structures, paving, and guardrail. The estimated construction cost for Alternate 1 is $7,800,000, Alternate 2 is $3,950,000 and Alternate 3 is $5,300,000. Table 5 shows the right of way cost, construction cost, and total cost of the alternates under consideration. O. NCDOT Recommended Alternate Alternate 3 is the construction option recommended by NCDOT. Alternate 3 provides the best balance of typical section and alignment improvements while minimizing impacts to the human environment. Natural environment impacts aze decreased by adding retaining walls and expressway gutter. Table 5 Alternate Cost Comparison Cost Item Alternate 1 Alternate 2 Alternate 3 recommended Construction Cost $7,800,000 $3,950,000 $5,300,000 Right of Way Cost $5,085,000 $5,085,000 $4,156,000 Total COSt $12,885,000 $9,035,000 $9,456,000 V. ENVIRONMENTAL EFFECTS A. Land Use Macon County is located in southwestern North Carolina. Macon County is bounded by Cherokee County to the west, the Georgia state line to the south, Jackson County to the east, Swain County to the north, Graham County to the northwest, and Clay County to the southwest. The Town of Franklin is the county seat and is located in the center of the county. 1. Residential Residences are scattered along the comdor; however, few homes have direct access to NC 28. Most homes access the corridor via connecting roads. The notable exception is the residential neighborhood on the west side of the Riverview Street and north of Iotla Street. Seven homes are located within 50 feet of the existing edge of pavement. 2. Commercial There are scattered commercial sites along the comdor consisting of two convenience stores and a Bed and Breakfast. Big D's convenience store is located on the east side of NC 28 south of Riverbend Road. The Village Trader Exxon is located on the west side of NC 28 south of Bryson City Road. Riverview Street and NC 28 intersect at the southern portion of the project. The Rivers Bridge Bed and Breakfast is located west of NC 28 and south of SR 1378 (Bennett Road). The Bed and Breakfast does not have direct access to NC 28 and would not be directly impacted by the project. 3. Industrial North of Airport Road on the west side of NC 28, there is an industrial site used for tractor trailer engine repairs. The business, Desoto Trail Construction, has direct access to NC 28. 4. Airport The Macon County Airport is located in the Iotla Valley approximately 3 miles north of Franklin and 1 mile west of NC 28. The airport plans to extend the existing runway from 4,400 feet to 5,001 feet in order to accommodate commercial flights. The airport is not in the proposed project area. 5. Zoning Macon County has established no zoning ordinance for the county. Local officials have proposed it in the past; however, the proposal was met with citizen opposition. The area surrounding the corridor within the Town of Franklin is zoned residential. 6. Future Plans for Development Neither Macon County nor the Town of Franklin currently have any existing plans for development along the proposed improvement area. 7. Local/Regional Land Use and/or Development Plans Neither the Macon County Planning Department nor the Town of Franklin has an adopted comprehensive plan. The proposed project is included as a pazt of the 1996 North Cazolina Department of Transportation Thoroughfare Plan for Macon County. In the Thoroughfaze Plan, NC 28 is identified as a Major Thoroughfare as shown by Figure 10. B. Farmland North Carolina Executive Order Number 96, Preservation of Prime Agricultural and Forest Lands, requires all state agencies to consider the impact of land acquisition and construction projects on prime farmland soils, as designated by the U.S. Natural Resources Conservation Service (MRCS). These soils are determined by the SCS based on criteria such as crop yield and level of input of economic resources. There aze no prime farmland resources or active farms within the project azea. C. Social and Economic Effects 1. Community Profile For the purposes of formulating the demographics of the azea, U.S. Census block groups were used. Census block groups that are within or touch the one-half-mile radius of the project were examined. Some of these census block groups that aze only partially within one-half-mile of the project were not used if the population from those block groups appeared to be out of the general project area. The census block groups used include azeas that fall outside of the general one-half-mile study azea; however, it is the closest approximation of the Impact Assessment Area. These census block groups make up the Demographic Study Area for the project. Census block groups used to define the Demographic Study Area include block groups: 9702001, 9701002, 9703001, 9703003, 9703002, 9703004, 9703005 and 9703007. a. Race, Ethnicity and Age According to the 2000 Census, the population of Macon County was 29,811, as seen in Table 6. Approximately 97.2 percent of the county is white, 1.2 percent is black, and 1.5 percent is Hispanic. Approximately 4.0 percent of the county's population is minority, including Hispanic. The study area's white population, 96.6 percent, exceeds that of the state 72.1 percent. The black population in the study azea is similar to that of the county, but far lower than the state. The minority population as a whole is a much smaller percentage in the study azea and the county as compared to the state's average. 10 Table 6 2000 Population by Race and Hispanic Origins Demo ra hic Stud Area Macon Coun North Carolina Number % Number % Number Total'Population-2000.. 7,567 100.0% 29,811 100.0% 8,049,313 100.0% Total Hispanic 153 2.0% 454 1.5% 378,963 4.7% White 7,309 96.6% 28,969 97.2% 5,804,656 72.1% Hispanic (White) 130 1.7% 341 1.1% 157,501 2.0% Black 91 1.2% 357 1.2% 1,737,545 21.6% Hispanic (Black) - 0.0% 4 0.0% 14,244 0.2% American Indian 37 0.5% 84 0.3% 99,551 1.2% Hispanic (American Indian - 0.0% 5 0.0% 4,218 0.1 Asian/Pacific Islander 41 0.5% 122 0.4% 117,672 1.5% Hispanic Asian/Pacific Islander 1 0.0% 1 0.0% 2,091 0.0% Other 89 1.2% 279 0.9% 289,889 3.6% Hispanic (Other) 22 0.3% 103 0.3% 200,909 2.5% Total Minority 388 5.1% 1,183 4.0% 2,402,158 29.8% ' Total minority is the sum of all persons other than white-non-Hispanic. Table 7 highlights the age cohorts across the study area, county, and state. The 0 to 18 grouping shows consistency across the three geographic divides. The study azea and the county show similaz percentages in the middle cohort, with the state showing a higher percentage by approximately 13 percent. In the oldest grouping, the state's percentage is half of the other geographic areas. The demographic study azea and county have almost twice the percentage of persons 65 and older than the state.

Income and Poverty Status According to the 2000 Census the median household income for the demographic study azea was $28,203, approximately 72.0 percent of that of the state, as shown in Table 8. The study azea median household income was slightly less than the median for Macon County at $32,139. The study azea has 15.6 percent of persons living below the poverty level. This percentage is slightly above the county at 12.6 percent and the state at 12.3 percent. However, the study azea was below the state and county for persons below 50 percent of poverty level at only 2.8 percent as shown in Table 8. 11 Table 8 2000 Income Measures and Persons Living Below Poverty Level Demo ra hic St ud Area Macon Couu North Carolina Number % Number % Number Median H.H.

Housing Characteristics The median home value for the demographic study area in 2000 was $92,312, as shown in Table 9. That was less than the median home value for Macon County at $103,700, and less than that of the state at $108,300. The homeownership rate in the demographic study area was 71.3 percent, which was lower than the rate in the county of 81.3 percent, but higher than the rate in the state, which was 69.4 percent. The median rent for the demographic study area was $494, which was slightly higher than the county at $485 and lower than the state at $548.

Business Activity/Employment Centers Macon County is the fastest growing county in western North Carolina with a 23 percent growth rate in the past 10 years. The State grew at 21.4 percent during the same period. The county leads the region in retail sales, per capita personal income, and median family income. Macon County's mixture of tourism and industry provides the azea with a diversified economy. Due to the abundance of natural resources, the local economy is oriented towazds retail trade and tourism. SR 1323 and NC 28 is an important route for north-south travel in the county. e. Public Facilities, Schools, Institutions, and Historic Sites There aze no schools within the project study azea; however, 18 to 20 students live along the project corridor. NC 28 is considered dangerous by the Macon County Boazd of Education. The numerous horizontal curves, steep terrain, and limited sight distance create safety concerns for school buses. 12 There is one church within the project area. The Church of Jesus Christ has frontage along NC 28; however, the primary access and parking aze located along a side street. Therefore, the project should have minimal impact on the facility. Macon County operates the Macon Area Transit Services system for transportation. They provide subscription and dial-a-ride services for their residents. f. Police, Fire, EMS, and Public Services There aze no police, fire, or EMS facilities located along SR 1323 or NC 28. Emergency response agencies in the azea welcome the proposed improvements to SR 1323 and NC 28, because the project should improve safety. g. Community/Neighborhood Description Surrounded by the beautiful mountains of the Nantahala National Forest in Western North Cazolina, Macon County is best known for its gem mines, its quilts & crafts, its history & heritage, and for the natural beauty of the surrounding mountains. The Town of Franklin is the largest municipality in Macon County, and is located along the Little Tennessee River, in the central part of Macon County. The elevation of Franklin is about 2,000 feet above sea-level and the population is about 3,000. Franklin has a beautiful panoramic view of the Smoky Mountains. The project within the Town of Franklin, is semi-urban. Lake Emery is located east of the corridor in this azea and the land is spazsely developed. A residential neighborhood is located west and adjacent to the project corridor, north of Iotla Street. The neighborhood consists of single family masonry dwelling units. Homes appeaz to be 15 to 30 years in age. Nine homes have frontage on SR 1323; however, only one of the homes has a driveway connection. Some residences in the neighborhood, particulazly those fronting SR 1323 have complete or partial views of Lake Emery. The project north of the Franklin corporate limits is a rural two lane mountain road with narrow vertical and horizontal curves and narrow lanes and shoulders. The road is chazacterized by limited commercial development and scattered residential development. 2. Project Impact Assessment a. Consistency with Local/Regional Plans The improvement is included in the North Cazolina Department of Transportation Thoroughfare Plan for Macon County in 1996. Neither Macon County nor the Town of Franklin has long range plans for the corridor. b. Economic Development Opportunities Economic development in Macon County is concentrated in the tourist/retall trade. The improvement of SR 1323 in conjunction with the Depot Street Extension should alleviate traffic congestion within downtown Franklin by providing an alternate route for truck traffic. The decreased congestion should aid in the development of a `mountain village' like atmosphere which should create a more economically viable climate for business owners who cater to the tourists' trade. 13 Within Macon County, the road would improve access to the local airport and to US 19 to the north. This should provide a safer and faster route for tourists who frequent the County's many recreational amenities. c. Traffic Congestion and Safety The purpose of the project is to improve roadway deficiencies along SR 1323 and NC 28. The Depot Street Extension, under construction, includes a 24-foot paved roadway with 8-foot shoulders (4-foot paved for bicycles). The project will create an alternate route for north-south truck traffic which currently uses Main Street in Franklin. The proposed action and the Depot Street Extension should alleviate congestion within the Town of Franklin by providing an alternate route for truck traffic. The proposed improvements should provide a safer facility for motorists, including school buses. d. Accessibility and Parking Accessibility to businesses in downtown Franklin should increase because truck traffic will have an alternate route along the Depot Street Extension to SR 1323 and NC 28. The proposed improvements may impact a portion of the pazking for Desoto Trail Construction and Big D's Convenience store. Public pazking does not exist and is not planned along SR 1323 or NC 28 in the project azea. e. Transit Considerations The improvements should create a safer route along SR 1323 and NC 28. By eliminating the unsafe curves and improving intersections, the potential for accidents should be reduced for everyday travel as well as travel during inclement weather. Improving the safety of NC 28 should assist the Macon Area Transit Services in meeting the needs of its clients. f. Bicycle, Pedestrian and Greenway Considerations Presently there aze no facilities along the road for bicycle or pedestrian uses. The project as proposed would have afour-foot wide paved shoulder section for bicycle usage. Macon County currently has an existing greenway pazalleling the east side of the Little Tennessee River, beginning at neaz the Franklin corporate limits and extending south into Franklin. Impacts to greenway access during construction should be minimal. g. Community Stability and Neighborhood Cohesion Community stability may be impacted as a result of the excavation (cuts) and increased traffic along SR 1323 within the Franklin corporate limits. Alternates 1 and 2 would impact several homes in a row fronting SR 1323. SR 1323 may isolate portions of the neighborhood leading to long-term decline in the quality of life for neighborhood residents. Alternate 3 avoids impacting these homes by using expressway gutter as a design element. North of Franklin, there are scattered residences located along the length of the project. Most of these homes access NC 28 via side streets. Neighborhood cohesion and community stability should not be greatly unpacted as a result of the project. 14 h. Tax Base Changes and Changes in Employment Improving safety along SR 1323 may have a positive impact for business owners in the Town of Franklin. The removal of truck traffic and congestion should improve the economic viability of downtown Franklin. i. VisualImpacts Along SR 1323, excavation (cuts) along the existing western side of SR 1323 is needed for Alternates 1, 2, and 3. Alternate 3 minimizes the amount of excavation needed by adding expressway gutter as an improvement option. There aze inherent risks to the visual environment when constructing or improving a highway in mountainous terrain due to the various cuts and fills necessary for project construction. Visual impacts north of the Franklin corporate limits should not be substantial because there aze limited azeas which will require deep cuts or lazge fills, NC 28 is primarily rural in nature, and there are no established recreational vistas. Therefore, visual impacts to the existing viewshed should be minimal. j. Scenic Rivers and Water Supply Watersheds There aze no designated Wild and Scenic Rivers in the project area. The entire project runs along the Little Tennessee River and is in the Little Tennessee River watershed. The project corridor traverses many tributaries of the Little Tennessee River. Lake Emory is located just outside the project azea and would not be directly affected by the project. k. Title VI and Environmental Justice Federal programs, under the statutes of Title VI of the Civil Rights Act of 1964, have requirements to protect individuals from discrimination on the basis of race, color, national origin, age, sex, disability, and religion. Furthermore, Executive Order 12898 "directs that programs, policies, and activities not have a disproportionately high and adverse human health and environmental effect on minority and low-income populations". The proposed action does not relocate minority residences or businesses. The percentage of persons below the poverty level in the study azea is slightly higher than the county and statewide averages. However, the relocation report (Appendix 1) shows that potential relocatees have income levels greater than $25,000 per yeaz. Therefore, this assessment finds no evidence or indication of benefit, harm, or disproportionate impact to any social group. 1. Indirect/Cumulative Impacts Indirect impacts may be caused by the actions of individuals that would occur as a result of the proposed transportation improvement. Based on the analysis presented in this section of the document, the following was concluded regazding indirect actions associated with the roadway improvement project. Two types of actions aze considered: • Change in the Rate of Development Along the Project Corridor • Change in the Character of Residential Neighborhoods Along the Corridor 1). Change in the Rate of Development Along the Project Corridor Among the major considerations in indirect impact assessment of new or improved roadways aze the effects of the activity on the pace and location of local and 15 regional development. Since this project involves widening pavement and improving both horizontal and vertical curvature to improve safety, it is not anticipated to create the conditions for inducing growth by itself. However, the completion of R-2408 in conjunction with the Depot Street Extension (TIP Project U-2929), may have impacts on traffic patterns and local economic development within the Town of Franklin. U-2929 extends Depot Street and will connect to the proposed action, thereby providing an alternative route to and from the downtown area. The new route could stimulate business in Franklin by alleviating traffic congestion within downtown Franklin and creating a more economically viable climate for business owners who cater to tourists. The increased economic viability may translate into long-term growth and development for the Town. The completion of the proposed action, as well as TIP Project U-2929, may have positive indirect impacts and cumulative impacts on local economic development within the Town of Franklin. Alleviating traffic congestion within downtown Franklin may create a more economically viable climate for business owners who cater to the tourists' trade. The increased economic viability may translate into long-term growth and development for the Town. 2). Change in the Character of Neighborhoods along the Corridor Proposed improvements to SR 1323 may contribute to the long-term change in character of the residential neighborhood west of the project corridor. Under Alternates 1 and 2, removal of the homes which front along Riverview Street may contribute to the decline of the quality of life for neighborhood residents through the noise introduced by truck traffic and the change in the quality of the visual environment. Alternate 3 minimizes impacts to this neighborhood. Improvements along NC 28 should not substantially impact the existing character of the residential neighborhoods north of SR 1323. 3. Relocation Impacts According to the relocation reports located in Appendix 1, all three alternates under consideration displace residences and businesses. According to the relocation report, there is more than adequate temporary housing available, either for sale or for rent, for all potential displacees. Table 10 shows a summary of the relocation impacts associated with the three alternates. Alternate 1 is expected to displace 25 residences and three businesses. Several of the residential displacements are part of an established neighborhood. Alternate 2 will relocate 16 residences and two businesses. Several of the residential displacees are part of an established neighborhood. According to the relocation report (Appendix 1), Alternate 3 is expected to relocate 10 residences and four businesses. Alternate 3 minimizes residential impacts through the use of expressway gutter and alignment shifts. Appendix 4 provides information on the NCDOT relocation assistance program. 16 Table 10 Relocation Impact Summary Alternate 1 Alternate 2 Alternate 3 recommended Owners 13 9 6 R id Tenants 12 7 4 es ences Total 25 16 10 Minori 0 0 0 Owners 3 2 4 B i Tenants 0 0 0 us nesses Total 3 2 4 Minori 0 0 0 Farms 0 0 0 Non-Profit O anizations 0 0 0 4. Cultural Resources a. Historic Architectural Resources This project is subject to compliance with Section 106 of the National Historic Preservation Act of 1966, as amended, implemented by the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106. Section 106 requires that if a federally permitted project has an effect on a property listed in or eligible for the National Register of Historic Places, the Advisory Council on Historic Preservation be given an opportunity to comment. This project is also subject to compliance with Section 4(f) of the Department of Transportation Act of 1966, as amended. An azchitectural survey for structures listed in the National Register or eligible for nomination to the National Register was conducted in the project azea. No properties in the project area are eligible for or listed in the National Register of Historic Places. b. Archaeological Resources Two of the six archaeological sites located within the project limits were recommended as eligible for listing in the National Register of Historic Places (NRHP). Sites 31MA588 and 31MA589 consist of dense concentrations of cultural remains and intact subsurface deposits dating to the Qualla Phase (A.D. 1450-1838). The two sites have been recommended as eligible for listing in the NRHP under Criterion D for their potential to yield significant information about the prehistory of the region. In regazds to both of the azchaeological sites, the project recommendations were for either site avoidance by planning construction on the east within the proposed right of way or further azchaeological work. The SHPO concurred with these recommendations according to a July 11, 2003 memorandum (Appendix 3). Alternates 1 and 2 would have an adverse effect on Sites 31MA588 and 31MA589. Alternate 3 maintains the existing topography along the west side of NC 28 and proposes to widen to the east. By employing retaining walls along the west side of NC 28, 17 impacts at the two azchaeological sites will be avoided. In addition, non-destructive techniques will be used for placing fill on the east side of 31MA588. Therefore, Alternate 3 as proposed, would have no adverse effect on 31MA588 and 31MA589. The SHPO concurred with these findings according to a Mazch 9, 2004 memorandum (Appendix 3). This information is made pursuant to Section 106 of the National Historic Preservation Act (1966, as amended) and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800. Section 4(f) does not apply to azcheological sites where the Administration, after consultation with the SHPO and the ACHP, determines that the azcheological resource is important chiefly because of what can be learned by data recovery and has minimal value for preservation in place. This exception applies both to situations where data recovery is undertaken or where the Administration decides, with agreement of the SHPO and, where applicable, the ACHP, not to recover the resource. D. Environmental Effects 1. Methodology Prior to the site visit, published resource information pertaining to the project area was reviewed and used in performing the site evaluation. Information sources include: • Geological Survey (USGS) quadrangle maps (Franklin). • USDA Soil Conservation Service, currently known as Natural Resource Conservation Service, Soil Survey of Macon County, North Carolina (1993). • NC Center for Geographic Information and Analysis Environmental Sensitivity Base Maps of Macon County (1995). Water resource information was obtained from publications of the NC Department of Environment, Health and Natural Resources (NCDEHNR, 1997, NCDENR, 2002). Information concerning the occurrence of federal and state protected species in the study area was obtained from the US Fish and Wildlife Service list of protected species (March 7, 2002) and from the NC Natural Heritage Program database of rare species and unique habitats. NC Natural Heritage Program files were reviewed for documented occurrences of state or federally listed species and locations of significant natural areas. NCDOT Environmental Specialists, Lynn Smith, Tim Savidge, Logan Williams, Michael Wood, and Jared Gray conducted a general reconnaissance of the project vicinity on June 12, 2001. An additional field visit, to delineate streams and wetlands, was conducted on March 26, 2002 by NCDOT Environmental Specialists, L. Smith, and LeiLani Paugh. Water resources were identified and their physical chazacteristics were recorded. Plant communities and their associated wildlife were also identified and described. Vegetative communities were mapped using aerial photography of the project site. Predictions regarding wildlife community composition involved general qualitative habitat assessment based on existing vegetative communities. Wildlife identification involved using a variety of observation techniques: qualitative habitat assessment based on vegetative communities, active searching, identifying characteristic signs of wildlife (sounds, scat, tracks and burrows). Jurisdictional wetlands, if present, were identified and evaluated based on criteria established in the "Corps of Engineers Wetland Delineation Manual" (Environmental Laboratory, 18 1987). Wetlands were classified based on the classification scheme of Cowardin, et al. (1979). Jurisdictional surface water determinations were performed using guidance provided by NC Division of Water Quality (DWQ),"Field Location of Streams, Ditches, and Ponding" (NCDENR-DWQ, 1997). 2. Terminology and Definitions Definitions for areal descriptions used in this report aze as follows: Project Study Area denotes the azea bounded by proposed construction limits; Project Vicinity describes an azea extending 0.5 mile on all sides of the project study azea; and Project Region is equivalent to an azea represented by a 7.5 minute USGS quadrangle map with the project occupying the central position. 3. Physical Resources Soil and water resources, occurring within the project area, aze discussed below with respect to possible environmental concerns. Soil properties and site topography significantly influence the potential for soil erosion and compaction, along with other possible construction limitations or management concerns. Water resources within the project area present important management limitations due to the need to regulate water movement and the increased potential for water quality degradation. Excessive soil disturbance resulting from construction activities can potentially alter both the flow and quality of water resources, limiting downstream uses. In addition, soil characteristics and the availability of water directly influence the composition and distribution of flora and fauna in biotic communities, thus affecting the chazacteristics of these resources. a. Regional Characteristics Macon County lies in the southwestern part of the Mountain Physiographic Province of North Cazolina. Elevation ranges from approximately 2000 to 2200 feet above sea level. The physiography of the county consists of high, intermediate and low mountains, low rolling hills, floodplains and low stream terraces. b. Soils There are fourteen soil map units located in the project azea. c. Water Resources This section contains information concerning surface water resources likely to be impacted by the proposed project. Water resource assessments include the physical chazacteristics, best usage standards, and water quality aspects of the water resources, along with their relationship to major regional drainage systems. Probable impacts to surface water resources aze also discussed, as aze means to minimise impacts. 1) Waters Impacted and Characteristics Water resources within the study azea aze located within the Little Tennessee River Basin. The Little Tennessee River drainage basin is located within the Blue Ridge Province of the Appalachian Mountains of western North Cazolina. The headwaters arise in Georgia. This basin encompasses about 1,800 square miles and covers six counties. Much of the land in the basin is federally owned and lies within Nantahala National Forest, 19 Great Smoky Mountains National Pazk or the Joyce Kilmer/Slick Rock Wilderness Area. The basin also includes the entire Cherokee Indian Reservation. Neazly half of the land in the Little Tennessee Basin is federal land, most of which is forested. Most of the remaining non-federal lands aze also forested. The streams and rivers of the Little Tennessee River basin aze still generally of high quality. However, there aze sedimentation and erosion problems occurring in the upper Little Tennessee River and several other streams in the basin. Sources of sedimentation include agriculture, mining operations, development, highway construction, and forest clearing. Several areas of concern include residential and commercial development in the Highlands azea, effects of nonpoint source runoff, sand dredging operations, stream bank erosion in the upper Little Tennessee River and runoff from gem mines to tributaries neaz Franklin. Waters within the project study azea aze contained within subbasin 04-04- 01 of the Upper Little Tennessee River basin. The water quality of rivers and streams in this subbasin is generally high. There aze five water resources in the project study azea, Rocky Branch, Iotla Creek, the Little Tennessee River, and two unnamed tributaries (Ut) to the Little Tennessee River (LTR) and Rocky Branch. Currently, the scope of work for the proposed action does not include the Little Tennessee River or Iotla Creek, therefore, no direct impacts are anticipated for these aquatic systems. Streams aze assigned a best usage classification by the NC Division of Water Quality (DWQ) which reflects water quality conditions and potential resource usage. These portions of the Little Tennessee River [Index No. 2-(1)], Rocky Branch (Index No. 2- 26), and Iotla Creek (Index No. 2-27) aze classified as "C". Class C refers to waters suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation and agriculture. Unnamed tributaries receive the same best usage classification as the named streams into which they flow. Therefore, the classifications for the Ut to Rocky Branch and the Ut to the Little Tennessee River aze C as well. No waters classified as High Quality Waters (HQW), Water Supplies (WS-I or WS-II) or Outstanding Resource Waters (ORW) occur within 1.0 mi (1.6 km) of the project study azea. No waters, identified on the North Cazolina 303(d) list, are located in the project study azea. 2) Physical Characteristics of Surface Waters Table 11 presents information on the physical characteristics of the streams and identifies their receiving streams. 3) Water Quality The DWQ is the state agency responsible for regulating and enforcing surface water quality regulations. To accomplish this task, the DWQ collects data on the biological, chemical and physical condition of North Cazolina surface waters. The DWQ has initiated a basinwide approach to water quality management for the 17 river basins within the state. The basinwide approach allows for more intensive sampling of biological, chemical and physical data that can be used in basinwide assessment 20 and planning. Benthic macroinvertebrates are intensively sampled for specific river basins. Benthic macroinvertebrates have proven to be a good indicator of water quality because they aze sensitive to subtle changes in water quality, have a relatively long life cycle, aze nonmobile (compazed to fish) and aze extremely diverse. The overall species richness and presence of indicator organisms help to assess the health of streams and rivers. All basins aze reassessed every five yeazs to detect changes in water quality and to facilitate National Pollution Dischazge Elimination System (NPDES) permit review.

' Feet z Inches s B=bedrock, Bo=Boulders, G=gravel, S=sand, Si=silt, C1=Clay There are two biological sampling sites located within the project azea. At the northern boundary of the project, Site B-3, located at the crossing of Little Tennessee River at NC 28, received a bioclassification of Good-Fair in 1999. Site B-27 is located at the crossing of Iotla Creek at SR 1372 (Iotla Church Road) and received a bioclassification of Good in 1999 (NCDENR-DWQ, 2002). Water pollution degrades surface waters making them unsafe for drinking, fishing, swimming, and other activities. As authorized by the Clean Water Act, the National Pollutant Discharge Elimination System (NPDES) permit program controls water pollution by regulating point sources that discharge pollutants into waters of the United States. Point sources aze discrete conveyances such as pipes or man-made ditches. Individual homes that aze connected to a municipal system, use a septic system, or do not have a surface dischazge do not need an NPDES permit; however, industrial, municipal, and other facilities must obtain permits if their discharges go directly to surface waters. Dischazge permits are issued 21 under the authority of North Carolina General Statute (NCGS) 143.215.1 and the NPDES program. The NPDES program was delegated to North Cazolina from the US Environmental Protection Agency (EPA). These permits serve as both state and federal permits. Table 12 lists the permitted dischargers located within the project study area (NCDEHNR-DEM, 1997).

Goehman Residence NCG550300 Little Tennessee River Pinaud Gem Mine NCG520016 Mason Branch • Nonpoint source discharge refers to runoff that enters surface waters through stormwater or snowmelt. Agricultural activities may serve as a source for various forms of nonpoint source pollutants. Land clearing and plowing disturb soils to a degree where they aze susceptible to erosion, which can lead to sedimentation in streams. Sediment is the most widespread cause of nonpoint source pollution in North Cazolina. Pesticides, chemical fertilizers, and land application of animal wastes can be transported via runoff to receiving streams and can potentially elevate concentrations of toxic compounds and nutrients. Animal wastes can also be a source of bacterial contamination and may elevate biochemical oxygen demand (BOD). Drainage ditches on poorly drained soils enhances the transportation of stormwater into surface waters (NCDEHNR- DEM, 1997). d. Summary of Anticipated Impacts Impacts to water resources in the project azea aze likely to result from activities associated with project construction. Activities likely to result in impacts aze clearing and grubbing on streambanks, riparian canopy removal, instream construction, fertilizers and pesticides used in revegetation, and pavement installation. The following impacts to surface water resources aze likely to result from the above mentioned construction activities. • Increased sedimentation and siltation downstream of the crossing and increased erosion in the project azea. • Changes in light incidence and water clarity due to increased sedimentation and vegetation removal. • Alteration of water levels and flows due to interruptions and/or additions to surface and ground water flow from construction. • Changes in and destabilization of water temperature due to vegetation removal. • Increased nutrient loading during construction via runoff from exposed azeas. 22 • Increased concentrations of toxic compounds from highway runoff. • Increased potential for release of toxic compounds such as fuel and oil from construction equipment and other vehicles. • Alteration of stream dischazge due to silt loading and changes in surface and groundwater drainage patterns. In order to minimize potential impacts to water resources in the project azea, NCDOT's Best Management Practices for the Protection of Surface Waters must be strictly enforced during the construction phase of the project. Impacts may be further reduced by limiting instream activities and revegetating stream banks immediately following the completion of grading. 4. Biotic Resources Biotic resources include terrestrial and aquatic communities. This section describes the biotic communities encountered in the project area, as well as the relationships between fauna and flora within these communities. The composition and distribution of biotic communities throughout the project azea are reflective of topography, soils, hydrology, and past and present land uses. Descriptions of the terrestrial systems aze presented in the context of plant community classifications. These classifications follow Schafale and Weakley where possible. Representative animal species, which aze likely to occur in these habitats (based on published range distributions), are also cited. Scientific nomenclature and common names (when applicable) are provided for each animal and plant species described. Subsequent references to the same organism refer to the common name only. Fauna observed during the site visits are denoted in the text with an asterisk (*). Each stratum (canopy, midstory, shrub, etc.) is described with regard to dominant species. Nomenclature of vascular plant species follows Radford et al. Faunal community composition is influenced by a variety of factors, including physiography, vegetative community type, habitat size and complexity (amount of stratification), moisture and temperature regimes and prior land uses. Qualitative habitat assessments along with actual observations of species were used to evaluate the faunal communities likely to be impacted. Animal taxonomy follows Potter, et al. (1980), Martof et al. (1980), Menhenick (1991), and Webster et al. (1985). Scientific nomenclature and common names (when applicable) are used for plant and animal species described. Subsequent references to the same organism will include the common name only. a. Biotic Communities There aze four distinct biotic communities identified within the project area. Community composition is reflective of the physiography, topography, moisture regime, and current and prior land uses of the area. All of the habitats aze reflective of varying degrees of recent human disturbance. The habitat complexity (stratification), and the abundance of mast producing plants provides numerous foraging and shelter opportunities, which results in a rich and diverse faunal community. These communities also provide travel comdors to access adjacent habitats, although fragmentation and habitat reduction from surrounding 23 development is threatening this function and is likely to result in declining biological diversity. 1) Montane Oak-Hickory Forest The moderately steep dry-mesic slope that is adjacent to the unnamed tributary to the Little Tennessee and interspersed along the project corridor exhibits a vegetative component that is most similaz to the Montane Oak-Hickory Forest described by Schafale and Weakley (1990). However, some of the chazacteristics of this natural community are lacking, likely due to previous disturbances. The canopy component is dominated by white oak and southern red oak (Quercus alba and Q. falcata), Virginia and white pine (Pinus virginiana and P. strobus), black walnut (Juglans nigra), mockernut hickory (Carya tomentosa), and interspersed with red spruce (P. rubens). Yellow poplaz (Liriodendron tulipifera) and hemlock (Tsuga sp.) aze present to a lesser extent. The dominance of white pine in the canopy along with the presence of yellow poplar is indicative of prior disturbance. Shingle oak (Quercus imbricaria), red cedar (Juniperus virginiana), flowering dogwood (Cornus florida), American holly (Ilex opaca), sassafras (Sassafras albidum), red maple (Acer rubrum), black cherry (Prunus serotina), and black gum (Nyssa sylvatica) comprise the understory. Shrub-size sprouts of American chestnut (Castanea dentata) are also present. Prior to being stricken with the chestnut blight, this species was a dominant canopy species in many of the forested communities in the mountain regions of North Cazolina. The invasion ofnon-native species such as Chinese privet (Ligustrum sinense), tree of Heaven (Ailanthus altissima), silverberry (Elaeagnus umbellata), and Japanese honeysuckle (Lonicera japonica) has neazly precluded native shrub and herbaceous species. Native shrubs such as blueberry (Vaccinium sp.), rose (Rosa spp.), and strawberry bush (Euonyrnus americanus) and herbs, including Christmas fern (Polystichium acrosticoides), milkweed (Asclepias sp.), trillium (Trillium sp.), and ebony spleenwort (Asplenium platyneuron) are present, but not in the numbers expected for this community type. Poison ivy (Toxicodendron radicans) comprises the vine layer. 2) Disturbed/Maintained Disturbed/maintained are lands that have been kept in anon-climax state by clearing and/or grazing. Once regular maintenance (disturbance) ceases, these azeas are populated by early successional species. This type of habitat occurs along road shoulders, within powerline corridors, and fallow fields scattered throughout the project study area. Vegetation within the disturbed/maintained community includes fescue (Festuca sp.), gamma grass (Tripsacum dactyloides), red and white clover (Trifolium pratense and T. repens), giant ragweed (Ambrosia trifida), violet (Viola sp.), lily (Cilium michauxii), wood sorrel (Oxalis sp.), daylily (Hemerocallis fulva), everlasting pea (Lathyrus latifolius), Queen Anne's lace (Daucus cazota), plantain (Plantago rugelii), Venus' looking-glass (Specularia perfoliata), Cazolina geranium (Geranium cazolinianum), New Jersey tea (Ceanothus americanus), mountain mint (Pycnanthemum sp.), black-eyed Susan (Rudbeckia hirta), alumroot (Heuchera sp.), cinquefoil (Potentilla sp.), mugwort (Artemisia vulgaris), dianthus (Dianthus armeria), vetch (Vicia sp.), lespedeza (Lespedeza sp.), woolly mullein (Verbascum thapsus), goldenrod (Solidago sp.), fire pink (Silene virginica), skullcap (Scuteilaria sp.), Indian 24 strawberry (Duchesnea indica), golden ragwort (Senicio aureus), and smooth sumac (Rhos glabra). Red maple and white pine are found scattered throughout the project azea along the roadside bordering fields and disturbed azeas. 3) Large Mountain Perennial Stream (Little Tennessee River) The Little Tennessee River flows under NC 28 beyond the northern terminus of the project. Trophic relationships of aquatic ecosystems aze very complex and contain elements from both terrestrial and aquatic systems. Reseazch (Gregory et. al 1991, Hynes 1970) has shown that a lazge amount of food chain energy of stream communities is derived from allochthonous (produced outside of stream ecosystem) sources, in the form of terrestrial detritus (leaves, stems etc.). Rocks, fallen debris (fallen branches, sticks etc.), and low velocity areas in the stream trap or retain detritus within the stream. The detritus is then broken down by detrivores and heterotrophic microorganisms, such as bacteria and fungi, and then further broken down into particulate size by macroinvertabrates referred to as shredders, such as aquatic insects (Plecoptera, Diptera and some Trichoptera), crayfish (Cambaridae) and amphipods (Amphipoda). A host of organisms referred to as filter feeders, or collectors filter the particulate organic matter from the water column. Some insect larvae such as caddisfly (Trichoptera) and blackfly (Simuliidae) larvae and freshwater mussels (Unionidae) and pea clams (Spharidae) are examples of collectors. The amount of allochthonous energy input within a stream varies seasonally. Autochthonous (produced within the stream ecosystem) energy sources include planktonic and benthic micro and macro algae as well as aquatic vasculaz vegetation. The amount of primary production occurring within a stream is greatly influenced by the riparian community due to attenuation of light energy (Gregory et al. 1991). Heavily shaded headwater streams receive very little solaz energy and consequently the trophic pathways are largely driven by allochthonous sources. Streams receiving more sunlight will have greater amounts of autochthonous energy. Primary consumers include grazers such as aquatic snails, other invertebrates and some species offish. Lazger organisms, or predators in turn, consume detritivores, collectors and primary consumers. Primary predators include some insect larvae (stoneflies, dragonflies), aquatic insects, small fish, turtles, and salamanders. Top level predators include larger fish, water snakes, aquatic mammals, and wading birds. US Fish and Wildlife Service Biologist, John Fridale, indicated the Little Tennessee River supports eight species of mussels including the federally endangered Appalachian elktoe (Alasmidonta raveneliana) and littlewing peazlymussel, and the state endangered Tennessee pigtoe (Fusconaia barnesiana). He stressed the biological importance of the mainstem of the Little Tennessee River as well as its tributaries because they provide the necessary spawning habitat for host fish. Cursory surveys in the Little Tennessee River were conducted using tactile and visual methods on June 12, 2001 by NCDOT biologists. Species observed include the Appalachian elktoe, the state endangered slippershell mussel (Alasmidonta viridis), and the state listed special concern wavyrayed lampmussel (Lampsilis fasciola). 25 Sampling data, from 1999 and 2001, was collected from the Little Tennessee River at Iotla Bridge by consultant biologist, William Mcl,arney, Ph.D. as part of a monitoring program of the Little Tennessee River Watershed. A total of 37 fish species have been recorded at this location. Whitetail shiner (Cyprinella galactura), wazpaint shiner (Luxilus coccogenis), river chub (Nocomis micropogon), rosyface shiner (Notropis rubellus), telescope shiner (Notropis telescopus), rock bass (Ambloplites rupestris), redbreast su~sh (Lepomis auritus), and gilt darter (Percina evides) were the most common species encountered. Portions of the Little Tennessee River are designated by the US Fish and Wildlife Service as "critical habitat" and "proposed critical habitat". Critical habitat is defined as "a specific geographic azea(s) that is essential for the conservation of a threatened or endangered species and that may require special management and protection". The main channel of the Little Tennessee River from the backwaters of Fontana Lake upstream to the North Cazolina-Georgia state lines is designated as "critical habitat" for the spotfin chub (Hybopsis monacha). The main stem of the Little Tennessee River, from the Lake Emory Dam in Franklin, Macon County to the backwaters of Fontana Reservoir in Swain County, is designated as "proposed critical habitat" for the Appalachian elktoe. Direct impacts aze not expected to occur to the Little Tennessee River given that project construction limits terminate south of the junction of NC 28 and the Little Tennessee River. 4) Small Mountain Perennial Stream (Rocky Branch, Iotla Creek, Ut to Little Tennessee River, and Ut to Rocky Branch) Three small streams flowing into the Little Tennessee River and one small stream flowing into Rocky Branch may be directly or indirectly impacted by the proposed project. Rocky Branch, Iotla Creek and the unnamed tributaries vary in size. Rocky Branch and Iotla Creek aze slightly lazger than the unnamed tributaries. Faunal community assemblages aze expected to be similaz at the project crossings. However, Rocky Branch and Iotla Creek are likely to have more developed communities compazed to the other streams producing a more diverse faunal community. Dr. McLarney has sampled Rocky Branch and Iotla Creek in the project vicinity. A total of 21 fish species were found within Rocky Branch neaz River Bend Road. Central stoneroller (Campostoma anomalum), warpaint shiner, Tennessee shiner (Notropis leuciodus), blacknose dace (Rhinichthys atratulus), and northern hog sucker (Hypentelium nigricans) are the most common species found in Rocky Branch. However, evaluation of the data suggests these species have decreased significantly from 1995 to 2001. Sixteen fish species were found in Iotla Creek (from mouth, 0.0-0.2 river miles to McCall residence). Other consumers in small stream ecosystems include salamanders, frogs, snakes, turtles, birds, and mammals. Snakes observed in Iotla Creek include northern water snake* (Nerodia sipedon) and queen snake* (Regina septemvittata). The painted turtle* (Chrysemys picta) and yellowbelly slider (Chrysemys scripts) were observed in a smaller tributary. These snakes aze important consumers offish, amphibians, and crustaceans. The belted kingfisher (Megaceryle alcyon) is a common consumer of small fish, frogs, and 26 crustaceans in mountain streams. Expected mammals in these creeks include, beaver (Castor canadensis), muskrat (Ondatra zibethicus), and raccoon. 5) Faunal Communities Due to the disturbed/degraded nature of all of the habitats in the project area, the faunal component is expected to consist of opportunistic animals able to adapt to the "edge" habitat created by human activities. Conversely, species which require large undisturbed forested habitats are likely absent from the project area. Primarily bird species such as downy woodpecker* (Picoides pubescens), red-bellied woodpecker* (Melanerpes carolinus), white-eyed vireo* (Vireo griseus), indigo bunting* (Passerina cyanea), eastern bluebird* (Sialia sialis), house finch* (Carpodacus mexicanus), red-breasted nuthatch* (Sitta canadensis), yellow-romped warbler (Dendroica coronata), white-breasted nuthatch (Sitta carolinensis), solitary vireo (Vireo solitarius), and northern cardinal (Cardinalis cardinalis) utilize the canopy. However, grey squirrel* (Sciurus carolinensis), southern flying squirrel (Glaucomys volans), Virginia opossum* (Didelphis virginiana), grey treefrog (Hyla chrysoscelis or H. versicolor), and eastern fence lizard (Sceloporus undulatus) also utilize this strata. Bats are also important components of forested communities. The northern long-eared bat (Myotis septentrionalis) and evening bat (Nycticeius humeralis) are two of the more common species that forage on forested hillsides, while little brown bat (Myotis lucifugus) and eastern pipistrelle bat (Pipistrellus subflavus) more commonly forage over water. Old buildings, hollow trees, or crevices under tree bark are often used as roost sites by these species. Caves and abandoned mine shafts (which are not present in the project area) are used as hiburnacula by many bat species in winter months. Top predators expected to occur here include great homed owl (Bubo virginianus), various hawks (Accipiter spp. and Buteo spp.), gray fox (Llrocyon cinereoargenteus), and copperhead (Agkistrodon contorix). These species are important in maintaining populations of rodents, small birds, and other small animals. Because of the open, relatively non-stratified nature of maintained/disturbed communities such as pasture/field and roadside habitats, resident vertebrate fauna, are generally small in size. Small mammals such as eastern cottontails* (Sylvilagus floridanus), least shrew, and house mouse (Mus musculus) are able to utilize the limited amount of vegetative cover of crop fields and pastures. The burrowing eastern mole (Scalopus aquaticus) and woodchuck (Marmots monax) are common in open areas bordering forested tracts. These small mammals are important prey items for black rat snake (Elaphae constrictor), red fox (Vulpes vulpes), red-tailed hawk (Bueto jamacensis), and other birds of prey. Few animals reside along roadsides because of the limited size and complexity of the habitat. Various species of birds feed along roadsides on seeds, berries, and insects. Some of these species include the northern cardinal, American robin* (Turdus migratorius), northern mockingbird* (Mimes polyglottos), and song sparrow* (Melospiza melodic). Snakes such as the black racer (Coluber constrictor) and eastern garter snake (Thamnophis sirtalis) may venture into this habitat to feed on insects and small mammals. 27 Virginia opossum* and raccoon frequently forage nocturnally in these habitats, or travel along roadways between habitats. These animals are often road kill victims. Consequently road kills attract a large number of scavenger species including turkey vulture (Carthartes aura) and common crow (Corvus brachyrhynchos), aswell asdomestic dogs and cats. b. Summary of Anticipated Biotic Community Impacts Construction of the proposed project will have various impacts on the biotic communities described. This section quantifies and qualifies these probable direct impacts, in terms of azea impacted (cleazed/modified), and ecological consequences to the communities, during the construction and operation of the proposed roadway. Secondary impacts, or impacts caused by other actions resulting from project construction (i.e. development) are also addressed. Recommendations to minimize/avoid impacts aze also given. 1) Terrestrial Community Impacts Plant communities found within the proposed project azea serve as nesting and sheltering habitat for various wildlife. Any construction related activities in or neaz these resources have the potential to impact biological functions. However, due to the size and scope of this project, it is anticipated that impacts to fauna will be minimal. This section quantifies and qualifies impacts to the natural resources in terms of area impacted and ecosystems affected. Temporary and permanent impacts aze considered here as well. a) Quantitative Impacts: Habitat Loss Portions of the two community types occurring in the project area will be cleazed or altered as a result of project construction. These alterations consequently affect the associated floral and faunal communities in a variety of ways. The estimated quantified impacts to these communities for both alternates aze shown in Table 13. Estimated impacts aze derived using the preliminary project plan sheets provided by NCDOT's Roadway Design Unit. The calculations are based on the slope-stake limits unless an easement exists outside of the slope-stake limits. Table 13 Estimated Terrestrial Community Impacts Community Alt. 1 Alt, 2 Alt 3 recommended Montane oak-hickory forest 7.8 acres 5.7 acres 9.5 acres Maintained/ Disturbed 40.3 acres 31.7 acres 33.0 acres Total Im acts 48.1 acres 37.4 acres 42.5 acres b) Faunal Population Impacts The plant communities found along the project alignment serve as shelter, nesting and foraging habitat for numerous species of wildlife. Individual mortalities aze likely to occur to numerous animals, during project construction as clearing will destroy 28 species living/nesting within trees, while grading/filling activities will impact ground dwelling species. Many other individuals will simply be displaced into other habitats. However, by concentrating these organisms into a smaller azea, over-utilization and degradation of the habitat may occur, which ultimately lowers the carrying capacity of the remaining habitat and is manifested in some species becoming more susceptible to disease, predation and starvation. Wildlife mortality caused by vehicles is a direct consequence of the highway facility once the road is in operation. Historically, the impacts of highway related mortality on the viability of wildlife populations were perceived to be minimal, except when "unusual circumstances," such as habitat loss/degradation, disease, etc., from other sources were also effecting the populations. As the density of road networks and traffic volumes increases, these "unusual circumstances" become more common, and highway-related mortality becomes more significant on animal populations. Traffic-related noise impacts on wildlife is another consequence of a road facility once in operation. Much of the reseazch on the effects of noise on wildlife species has focused on noise events of high level but short duration, such as aircrafts, and construction and blasting activities. Such noise events can cause startle effects (fleeing from nest, panic behavior, etc.). The more constant, lower level noise sources such as highway traffic, have only recently been investigated for their impacts on wildlife. Changes in plant community composition in the surrounding habitats aze another indirect consequence of road construction. Studies have shown that invasion of exotic plant species into adjacent forest habitats is facilitated by roadways. The biotic communities within the project azea have already been degraded by invasive species and project construction will not affect these species. 2) Aquatic Community Impacts Reseazch in North Cazolina streams has shown that water quality and biota is greatly affected by land use. Streams in urbanized settings have comparatively lower water quality and corresponding lower biotic diversity than streams in forested areas. The associated watershed of the Little Tennessee River above Lake Emory has been degraded by urbanization (Franklin) and agricultural sedimentation problems. Impacts to stream communities resulting from project construction can be directly attributed to sedimentation, rechannelization/loss of natural channel, substrate disturbance, and reduced water quality resulting from project construction. Although substrate disturbance and sedimentation may be temporary processes during the construction phase of this project, environmental impacts from these processes may be long-lived or irreversible. Suspended solids, sedimentation and turbidity result in reduced biodiversity as well as a decline in productivity at all trophic levels. Mobile aquatic organisms may escape some of the effects of siltation; however, the abrasive action of sediment in the water column is harmful to the gills offish, 29 crustaceans, and larval amphibian and insects. Spawning habitats for fish may become filled with sediment, diminishing reproductive success and inevitably reducing populations. Benthic organisms aze particulazly sensitive to construction activities such as dredging, filling, culvert construction/extension, pile-driving operations, and slope stabilization. These activities physically disturb the substrate, resulting in loss of sessile benthic organisms. Improperly placed culverts can have significant impacts on stream morphology. Stream impacts often associated with culverts include alteration of flow, scour at culvert outlets, degradation of adjacent streambanks and headcutting. Loss of natural stream channel will eliminate the existing substrate and associated fauna. Many of these aquatic organisms aze slow to recover or repopulate an azea, because they require a stabilized substrate for attachment. Substrate stability may take a long time to develop, therefore, changes in community composition will occur, particulazly in relocated segments. Increased water temperature/decreased dissolved oxygen caused by loss of riparian vegetation, and the introduction of toxic materials into the water is a potential consequence of project construction. This water quality degradation will result in a continual decline of species diversity and productivity, as the intolerant organisms disappeaz. 5. Jurisdictional Topics This section provides inventories and impact analyses pertinent to two significant regulatory issues: waters of the United States and rare and protected species. These issues retain particular significance because of federal and state mandates, which regulate their protection. This section deals specifically with the impact analyses required to satisfy regulatory authority prior to project construction. a. Waters of the United States Surface waters and wetlands fall under the broad category of "waters of the United States," as defined in Section 33 of the Code of Federal Register (CFR) Part 328.3. Any action that proposes to dredge or place fill material into surface waters or wetlands falls under the jurisdiction of the US Army Corps of Engineers (LJSACE) under Section 404 of the Clean Water Act (33 U.S.C. 1344). Surface waters include all standing or flowing waters which have commercial or recreational value to the public. Wetlands aze identified based on the presence of hydric soils, hydrophytic vegetation, and saturated or flooded conditions during all or part of the growing season. 1). Characteristics of Wetlands and Surface Waters Potential wetland communities were evaluated using the criteria specified in the 1987 "Corps of Engineers Wetlands Delineation Manual". For an azea to be considered a "wetland", the following three specifications must be met; 1) presence of hydric soils (low soil chroma values), 2) presence of hydrophytic vegetation, and 3) evidence of hydrology, including; saturated soils, stained leaf litter, oxidized root channels, matted vegetation, high water marks on trees, buttressed tree bases and surface roots.. Wetlands aze not located within the slope-stake limits or within easements shown on the project plan sheets for any alternate. 30 Impacts to jurisdictional surface waters aze calculated based on the lineaz feet of the stream that is located within the slope-stake limits or easements shown on the preliminazy project plan sheets. These impacts do not include portions of the streams that aze already encased in a pipe or culvert. Impacts to jurisdictional surface waters aze identified in Table 14. Table 14 Estimated Impacts to Jurisdictional Surface Waters Water Resource Alternate 1 Alternate 2 Alternate 3 recommended Ut to Little Tennessee River 140 feet 65 feet 70 feet Ut to Roc Branch 35 feet 35 feet 100 feet Roc Branch 400 feet 330 feet 305 feet Iotla Creek 0 0 0 Little Tennessee River 0 0 0 Totals: 575 feet 430 feet 475 feet 2). Permits Impacts to jurisdictional surface waters are anticipated from the proposed project. As a result, construction activities will require permits and certifications from various regulatory agencies in chazge of protecting the water quality of public water resources. A Nationwide 33 CFR 330.5(a) (14) Permit is likely to be applicable for project construction at each crossing of the waters of the United States if final design plans show individual stream impacts will be less than 300 feet. Currently, Alternate 3 (recommended) impacts approximately 305 lineaz feet of Rocky Branch. The impact to Rocky Branch may be reduced to less than 300 feet, after detailed survey and mapping information becomes available. If stream impacts exceed 300 feet at Rocky Branch, an Individual Permit will be required. These permits authorize activities undertaken, assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency or department where that agency or department has determined the pursuant to the Council on Environmental Quality regulation for implementing the procedural provisions of the National Environmental Policy Act: (1) that the activity, work, or dischazge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and; (2) that the office of the Chief of Engineers has been furnished notice of the agency' or department's application for the categorical exclusion and concurs with that determination. 31 This project will also require a 401 Water Quality Certification from the DWQ prior to the issuance of the Nationwide Permit. Section 401 of the Clean Water Act requires that the state issue or deny water certification for any federally permitted or licensed activity that may result in a dischazge to waters of the United States. Section 401 Certification states that water quality standazds will not be violated. The proposed project is located in the Tennessee Valley Watershed. A permit pursuant to Section 26a of the TVA Act is required for obstructions involving streams or floodplains in the Tennessee River drainage basin. TVA is a cooperating agency for this project. 3). Avoidance, Minimization, and Mitigation The USACE has adopted through the Council on Environmental Quality (CEQ) a wetland mitigation policy which embraces the concept of "no net loss of wetlands" and sequencing. The purpose of this policy is to restore and maintain the chemical, biological and physical integrity of waters of he United States, and specifically wetlands. Mitigation of wetland impacts has been defined by the CEQ to include: avoiding impacts (to wetlands), minimizing impacts, rectifying impacts, reducing impacts over time and compensating for impacts (40 CFR 1508.20). Each of these three aspects (avoidance, minimization and compensatory mitigation) must be considered sequentially. Avoidance mitigation examines all appropriate and practicable possibilities of averting impacts to waters of the United States. According to a 1990 Memorandum of Agreement (MOA) between the EPA and the USACE, in determining "appropriate and practicable" measures to offset unavoidable impacts, such measures should be appropriate to the scope and degree of those impacts and practicable in terms of cost, existing technology and logistics in light of overall project purposes. There are no wetlands in the project area to avoid or minimize impacts. However, the proposed roadway improvement project does impact streams. Widening the existing roadway will likely require replacing the existing culvert on NC 28 at Rocky Branch. Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts to waters of the United States. Implementation of these steps will be required through project modifications and permit conditions. Minimisation typically focuses on decreasing the footprint of the proposed project through the reduction to median widths, right-of--way widths, fill slopes and/or road shoulder widths. All efforts will be made to decrease impacts to surface waters. Compazed to Alternate 1, Alternate 3 (recommended) reduces impacts to Rocky Branch by approximately 95 feet, as shown by Table 12. Compensatory mitigation is not normally considered until anticipated unpacts to waters of the United States have been avoided and minimized to the maximum extent possible. It is recognized that "no net loss of wetlands" functions and values may not be achieved in each and every permit action. In accordance with 15A NCAC.2H .0506(h), NCDWQ may require compensatory mitigation for projects with greater to or equal than 1.0 acre of impacts to jurisdictional wetlands or greater than or equal to 1501ineaz feet of total perennial stream impacts. Furthermore, in accordance with 67 FR 2020, 2092; January 15, 32 2002, the USACE requires compensatory mitigation when necessary to ensure that adverse effects to the aquatic environment are minimal. The size and type of proposed project impact and function and value of the impacted aquatic resource are factors considered in determining acceptability of appropriate and practicable compensatory mitigation. Appropriate and practicable compensatory mitigation is required for unavoidable adverse impacts which remain after all appropriate and practicable minimization has been required. Compensatory actions often include restoration, preservation and enhancement, and creation of waters of the United States. Such actions should be undertaken first in azeas adjacent to or contiguous to the dischazge site. Due to the impacts associated with this widening project, compensatory mitigation may be required. Final compensatory wetland and stream mitigation requirements will be determined by the USACE under the statutory provisions of CWA §404 and the January 15, 2002 Final Notice of Issuance of Nationwide Permits. b. Rare and Protected Species Some populations of fauna and flora have been in, or aze in, the process of decline either due to natural forces or their inability to coexist with human development. Federal law (under the provisions of the Endangered Species Act of 1973, as amended) requires that any action, likely to adversely affect a species classified asfederally-protected, be subject to review by the US Fish and Wildlife Service. Other species may receive additional protection under sepazate state laws. 1). Federally-Protected Species Plants and animals with federal classifications of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) aze protected under the provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of Mazch 7, 2002, the US Fish and Wildlife Service lists seven federally protected species for Macon County as shown in Table 15. Table 15 Federally-Protected Species in Macon County Common Name Scientific Name Status Bo Turtle Clemm s muhlenber 11 Threatened S/A S otfin Chub C rinella =H bo sis monacha Threatened Indiana Bat M otis sodalis Endan ered A alachian Elktoe Alasmidonta raveneliana Endan ered Littlewin Pearl ussel Pe ias abula Endan ered Small Whorled Po onia Isotria medeoloides Threatened Vir inia S iraea S iraea vir iniana Threatened • ~naangeren (a species that is ui danger of extinction throughout all or a significant portion of its range). • Threatened (a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range). • Threatened (S/A) denotes Threatened by Similarity of Appearance (a species that is threatened due to similarity of appearance with other raze species and is listed for its protection). 33 Clemmys muhlenbergii (bog turtle) Threatened due to Similarity of Appearance Family: Emydidae Date Listed: O1 May 1997 The bog turtle is North Carolina's smallest turtle, measuring 3 to 4 inches in length. It has a dark brown carapace and a black plastron. The bright orange or yellow blotch on each side of the head and neck is a readily identifiable characteristic. The bog turtle inhabits damp grassy fields, bogs and marshes in the mountains and western Piedmont. The bog turtle is shy and secretive, and will burrow rapidly in mud or debris when disturbed. The bog turtle forages on insects, worms, snails, amphibians and seeds. In June or July, three to five eggs are laid in a shallow nest in moss or loose soil. The eggs hatch in about 55 days. BIOLOGICAL CONCLUSION: NOT APPLICABLE The bog turtle is listed as Threatened due to Similarity of Appearance (T S/A). This is due to its similarity of appearance to the northern population of bog turtle that is federally protected. T S/A species are not subject to Section 7 consultation and a biological conclusion for this species is not required. Hybopsis monacha (spotfin chub) Threatened Formerly: Cyprinella monacha Animal Family: Cyprinidae Date Listed: 9/9/77 The spotfin chub is a small minnow that is olive green above with silver sides and the females are whitish below. The males have a brilliant turquoise blue coloring on their backs, sides of the head, and mid-lateral part of the body, fins are tipped with white during peak development. Males and females are both characterized by a prominent black spot on the lower part of the caudal fin. The spotfin chub now occurs in the Little Tennessee River drainage system found in Swain and Macon Counties. This minnow inhabits moderate to large streams, 49 to 230 feet in width. These streams should have a good current, clear water, cool to warm temperatures, and pools alternating with riilles. Specimens of spotfin chub have been taken from a variety of substrates but rarely from significantly silted substrates. The spotfin chub feeds on insect larvae. It is considered to be a "sight feeder" that selects its prey off of clean substrates. BIOLOGICAL CONCLUSION: UNRESOLVED According to North Carolina Natural Heritage Program records, the spotfin chub occurs within the project study area in the Little Tennessee River and approximately 1.0 mile outside the project study area in Iotla Creek. The Little Tennessee River, main channel from the backwaters of Fontana Lake upstream to the North Carolina-Georgia state line, has been designated as critical 34 habitat for the spotfin chub by the US Fish and Wildlife Service. The Little Tennessee River is within the project vicinity and the project study area contains tributaries that flow into the critical habitat area. Additional fish surveys and a Section 7 consultation will be required for this project. Alasmidonta raveneliana (Appalachian elktoe) Endangered Animal Family: Unionidae Date Listed: 9/3/93 The Appalachian elktoe is a small mussel with a maximum length reaching up to 3 inches. Its shell is thin although the shell is not fragile nor subovate (kidney-shaped). The periostracum (outer shell) of the adult Appalachian elktoe is dark brown in color, while juveniles have a yellowish-brown color. Two known populations of the Appalachian elktoe exist in North Carolina; the Nolichucky River (including its tributaries of the Cane River and the North Toe River), and the Little Tennessee River and its tributaries. The Appalachian elktoe has been observed in gravelly substrates often mixed with cobble and boulders, in cracks of bedrock and in relatively silt-free, coarse sandy substrates. BIOLOGICAL CONCLUSION: UNRESOLVED A survey of the Little Tennessee River was conducted on June 12, 2001 by NCDOT biologists at the NC 28 crossing. Appalachian elktoe was found to exist in this area. The Little Tennessee River is within the project vicinity and the project study area contains tributaries that flow into the Little Tennessee River. Currently, the biological conclusion for this species remains unresolved. Additional mussel surveys and a Section 7 consultation will be required for this project. Pegias fabula (littlewing pearlymussel) Endangered Animal Family: Unionidae Date Listed: considered 6/22/84 The littlewing pearly mussel is a small mussel having the anterior portion of its shell evenly rounded and semi-circular. The periostrium is usually eroded, giving the shell a chalky or ashy white appearance. If the periostracum is present it is light green or yellowish-brown with dark rays on the anterior surface that vary in width. It has well developed but incomplete hinge teeth and the lateral teeth are either vestigial or completely lacking. The littlewing pearly mussel inhabits small to medium sized streams with low turbidity, cool water, and a high to moderate gradient. This mussel can be found buried in gravel or beneath boulders and slabrock, lying on top of the substratum in riffles, and partly buried or on the surface of the substratum in the transition zone between long pools and riffles. It has been suggested that the best times to find this mussel are in late spring and in the late fall, when they are on top or partly buried in the substratum during spawning (Ahlstedt 1986). 35 BIOLOGICAL CONCLUSION: UNRESOLVED Known populations of littlewing pearly mussel have been found downstream of the project area on the Little Tennessee River and its tributaries. The Little Tennessee River is within the project vicinity and the project study area contains tributaries that flow into the Little Tennessee River. Currently, the biological conclusion for this species remains unresolved. Additional mussel surveys and a Section 7 consultation will be required for this project. Isotria medeoloides (small whorled pogonia) Threatened Plant Family: Orchidaceae Date Listed: 9/10/82 Flowers Present: mid May-mid June Small whorled pogonia is a perennial orchid having long pubescent roots and a hollow stem. Stems terminate in a whorl of five or six light green, elliptical leaves that are somewhat pointed. One or two light green flowers are produced at the end of the stem. Flowers of small- whorled pogonia have short sepals. The small whorled pogonia grows in "second growth deciduous" or deciduous-coniferous forests, with an open canopy, open shrub layer, and sparse herb layer. It prefers acidic soils. Flowering is inhibited in areas where there is relatively high shrub coverage or high sapling density. BIOLOGICAL CONCLUSION: NO EFFECT Typical habitat for the small whorled pogonia, deciduous-coniferous forests, with an open canopy, open shrub layer, and sparse herb layer, is not present within the project area. However, the project was surveyed for this species on June 12, 2001 by NCDOT biologists, and no species were found. In addition, a search of the North Carolina Natural Heritage Program database of rare species and unique habitats on May 5, 2002 shows no records of this species being found in the project area. Thus, this project will have no effect on this species. spiraea virginiana (Virginia spiraea) Threatened Plant Family: Rosaceae Date Listed: 6/15/90 Flowers Present: June -July This shrub has arching and upright stems that grow from one to three meters tall. Virginia spiraea often grows in dense clumps, having alternate leaves which vary greatly in size, shape, and degree of serration. The leaves are green above and usually somewhat glaucous below. The cream colored flowers are present from June to July and occur in branched, flat-topped inflorescence. Virginia spiraea is easily located during the late fall while herbaceous growth is minimal and the leaves are down. 36 Virginia spiraea is found in a very narrow range of habitats in the mountains of North Carolina. Habitats for the plants consist of scoured banks of high gradient streams, on meander scrolls; point bars, natural levees, or braided features of lower reaches. The scour must be sufficient to prevent canopy closure, but not extreme enough to completely remove small, woody species. This species occurs in the maximum floodplain, usually at the water's edge with various other disturbance-dependent species. It is most successful in areas with full sunlight, but can survive in shaded areas until it is released from competition. BIOLOGICAL CONCLUSION: NO EFFECT Suitable habitat for Virginia spiraea occurs minimally within the project area. However, a plant-by-plant survey was conducted on June 12, 2001 by NCDOT biologists and no specimens of Virginia spiraea were observed. In addition, a search of the North Carolina Natural Heritage Program database of rare species and unique habitats on May 5, 2002 shows no records of this species being found in the project area. Thus, this project will have no effect on this species. Myotis sodalis (Indiana bat) Endangered Animal Family: Vespertilionidae Date Listed: 3/11/67 Distribution in N.C.: Jackson, Mitchell, Rutherford, Swain, Graham, and Macon. Adult Indiana bats are the smallest bats found in western North Carolina. Several characteristics can be used to distinguish them from other bats; the hair on the feet is short and does nat extend past the tips of the claws, the tail membrane is attached to the base of the keel, and the calcar (cartilaginous spur from the bats heel which helps support tail or interfemoral membrane) is keeled. The Indiana bats dorsal fur is brown in color and the ventral fur is lighter with a cinnamon hue. The range of the Indiana bat centers around cavernous limestone regions in the eastern United States. The Indiana bat has different summer and winter habitat requirements. Winter habitat is in caves and abandoned mines with standing water. The bat migrates to the winter habitat between September and November; they stay there with occasional periods of activity until they emerge in mid-March to early May. Hibernation only occurs in regions where winter temperatures are stable and are around four degrees Celsius. Little is known of the summer habitat of the Indiana bat. It is thought that they disperse throughout their range and spend the summer foraging alone over streams or along forest margins. They have been found under loose bark on dead and living trees along small to medium-sized streams. Optimum foraging is over streams with mature riparian vegetation overhanging the water by more than 10 feet. Streams that have been stripped of their riparian vegetation do not appear to offer suitable foraging habitat. Rivers as foraging areas and as migration routes are extremely important to this species. BIOLOGICAL CONCLUSION: MAY EFFECT -NOT LIKELY TO ADVERSELY AFFECT 37 The consulting firm Eco-Tech has completed surveys for the project, using mist-netting guidelines set in the Indiana bat recovery plan and after coordinating with the US Fish and Wildlife Service. The underside of bridges were also checked as potential bat habitat. Five different species of bats were found, none of which is federally protected. Recommendations for protecting bats along the proposed TIP projects are as follows: • As long as they are not problematic, dead and damaged trees should be left standing • Stream degradation by channelization, siltation or other pollution should be prevented as much as possible in order to protect macroinvertebrate food sources for bats. 2). Federal Species of Concern and State Listed Species Federal species of concern aze not afforded federal protection under the Endangered Species Act and aze not subject to any of its provisions, including Section 7, until they aze formally proposed or listed as Threatened or Endangered. However, the status of these species is subject to change, and so should be included for consideration. Federal Species of Concern (FSC) are defined as a species, which is under consideration for listing for, which there is insufficient information to support listing. In addition, organisms which aze listed as Endangered (E), Threatened (T), or Special Concern (SC) by the North Cazolina Natural Heritage Program list of Rare Plant and Animal Species aze afforded state protection under the NC State Endangered Species Act and the NC Plant Protection and Conservation Act of 1979. Table 16 lists federal species of concern, the state status of these species (if afforded state protection), and the potential for suitable habitat in the project area for each species. This species list is provided for information purposes as the protection status of these species may be upgraded in the future. A review of the NC Natural Heritage Program database of raze species and unique habitats on May 5, 2002 shows no occurrences of raze species in the project study area. However, the olive darter and sicklefm redhorse do occur in the Little Tennessee River, approximately 1000 feet from the intersection of NC 28 and the Little Tennessee River. The hellbender occurs less than 1.0 mile from the southern terminus of the project in the Little Tennessee River. Surveys for FSC species were not conducted during the site visit. 6. Flood Hazard Evaluation Macon County is currently participating in the National Flood Insurance Regulaz Program and no detailed flood studies have been performed within the project azea. The DENR Environmental Sensitivity Maps show that the project is not located within any sensitive water azeas. Existing drainage patterns will be maintained to the extent practicable. Erosion and sedunentation will be controlled through the specification, installation, and maintenance of standazd erosion and sedimentation control methods. Groundwater resources will not be affected by the project since the roadway is fill and existing cut. NCDOT's Hydraulic Design Unit will coordinate with the Federal Emergency Management Agency and local authorities in the final design to ensure compliance with applicable floodplain ordinances. 38 Table 16 Federal Species of Concern for Macon County Common Name Scientific Name NC Status Habitat Bachman's S arrow Aimo hila aestivalis SC* YES Green Salamander Aneides aeneus E NO Olive-Sided Fl catcher Conto us coo eri SC* NO Rafines ue's Bi -Eared Bat Co norhinus ra mes uii SC PT * YES Hellbender C tobranchus alle aniensis SC YES Cerulean Warbler Dendroica cerulea SR YES Southern A alachian Woodrat Neotoma oridana haematoreia SC YES Olive Darter Percina s uamata SC YES New En land Cottontail S Ivila s transitionalis SR* YES A alachian Bewick's Wren Th omanes bewickii altos E* YES Sicklefin Redhorse Moxostoma s .

Hazardous Materials A "Limited Environmental Site Assessment" for the project azea was conducted to identify azeas of potential environmental concern, such as underground storage tanks (CYST), above ground storage tanks (AST), hazardous waste sites, or similar problem sites. There aze no landfills or superfund sites within the project limits. The following is a description of the potential areas of concern in the vicinity of the proposed action. The Village Trader is an active gas station/mini-mart located in the southwest quadrant at the intersection of NC 28 and SR 1323. The Division of Waste Management (DWM) UST registry shows that two (2) gasoline tanks, one (1) diesel tank and one (1) kerosene tank are currently in use at this site. The current UST areas are about 69 to 100 feet from the centerline of NC 28. No monitoring wells were noted at the site and the site does not appear to be under remediation. There are no anticipated impacts associated with any of the alternatives being studied for this project The Desoto Trail Construction Company is located on the west side of NC 28. The pump island is located in the front of the building about 50 feet from the centerline of NC 28. Four UST tanks were located on the property; two (2) diesel tanks, one (1) gasoline tank, and one (1) waste oil tank (unpermitted). UST azea is located approximately 65 feet from the centerline of NC 28. The site does not appear to be listed in the UST registry. No monitoring wells were noted on the site and the site does not appear to be under remediation. All of the alternatives will have possible impacts on the pumps at this site. Only Alternate 2 may impact the USTs at this site. Jay's Big D is a gas station /convenience store located on the eastside of NC 28 approximately 200 feet north of the Desoto Trail Construction Company. A review of the petroleum underground storage tank database for Macon County indicates that three (3) USTs aze located on the property. One tank appears to be under the building on the southwest corner, while another tank is partially exposed at the south end of the store. USTs aze located approximately 80 feet from the centerline of NC 28. Five (5) ASTs are located on the site and are in current use. No monitoring wells were noted at the site and the site does not appear to be under remediation at this time. Only Alternate 1 will likely impact the pumps at this site. Crisp's Used Cazs & Parts is located west of NC 28 approximately 0.1 mile north of SR 1381 (Lee Tallent Road). This property is a junkyard and contains oil stains, batteries,. engines, transmissions, and junk cazs. There does not appear to be any underground storage 40 tanks on the property. There aze no anticipated impacts for any of the alternates under consideration. 8. Noise This analysis was performed to determine the effect on traffic noise levels in the immediate project azea as the result of proposed improvements to SR 1323 (Riverview Street) and NC 28 in Macon County. a. Characteristics of Noise Noise is basically defined as unwanted sound. It is emitted from many sources including airplanes, factories, railroads, power generation plants, and highway vehicles. Highway noise, or traffic noise, is usually a composite of noises from engine exhaust, drive train, and tire-roadway interaction. The magnitude of noise is usually described by its sound pressure. Since the range of sound pressure varies greatly, a logarithmic scale is used to relate sound pressures to some common reference level, usually the decibel (dB). Sound pressures described in decibels are called sound pressure levels and aze often defined in terms of frequency weighted scales (A, B, C, or D). The weighted-A decibel scale is used almost exclusively in vehicle noise measurements because it places the most emphasis on the frequency range to which the human ear is most sensitive (1,000-6,000 Hertz). Sound levels measured using aweighted-A decibel scale aze often expressed as dBA. Throughout this report, all noise levels will be expressed in dBA's. Several examples of noise pressure levels in dBA aze listed in Appendix 2, Table N1. Review of Table N1 (Appendix 2) indicates that most individuals in urbanized azeas aze exposed to fairly high noise levels from many sources as they go about their daily activities. The degree of disturbance or annoyance of unwanted sound depends essentially on three things: 1. The amount and nature of the intruding noise 2. The relationship between the background noise and the intruding noise 3. The type of activity occurring when the noise is heazd Over time, particulazly if the noises occur at predicted intervals and are expected individuals tend to accept the noises that intrude into their lives. Attempts have been made to regulate many of these types of noises including. airplane noise, factory noise, railroad noise, and highway traffic noise. In relation to highway traffic noise, methods of analysis and control have developed rapidly over the past few yeazs. b. Noise Abatement Criteria The Federal Highway Administration (FHWA) has developed Noise Abatement Criteria (NAC) and procedures to be used in the planning and design of highways to determine whether highway noise levels are or are not compatible with various land uses. These abatement criteria and procedures aze set forth in the aforementioned Federal reference 41 (Title 23 CFR Part 772). A summary of the noise abatement criteria for various land uses is presented in Table N2 (Appendix 2). The Leq, or equivalent sound level, is the level of constant sound which in a given situation and time period has the same energy as does time varying sound. In other words, the fluctuating sound levels of traffic noise aze represented in terms of a steady noise level with the same energy content. c. Ambient Noise Levels Ambient noise measurements were taken in the vicinity of the project to determine ambient (existing) noise levels for the identified land uses. The purpose of this noise level information was to quantify the existing acoustic environment and to provide a base for assessing the impact of noise level increases. The existing Leq noise levels in the project azea were measured at 50 feet from edge of pavement of the neazest lane of traffic ranged from 58.7 dBA to 65.9 dBA. The ambient measurement location is presented in Table N3 (Appendix 2). A background noise level of 45 dBA was determined for the project to be used in azeas where traffic noise was not the predominant source. The existing roadway and traffic conditions were used with the most current prediction model for traffic noise in order to compaze calculated existing noise levels with the measured existing noise levels. The computer modeled existing noise levels averaged less than 1 dBA than the measured noise levels. Hence, the computer model is a reliable tool in the prediction of noise levels. Differences in dBA levels can be attributed to "bunching" of vehicles, low traffic volumes, and actual vehicle speeds versus the computer's "evenly- spaced" vehicles and single vehiculaz speed. d. Procedure for Predicting Future Noise Levels In general, traffic conditions consist of a lazge number of variables that describe different cazs driving at different speeds through a continual changing highway configuration and surrounding terrain. Due to the complexity of the problem, certain assumptions and simplifications must be made to predict highway traffic noise. The procedure used to predict future noise levels in this study was the Traffic Noise Model (TNM) 2.1. The TNM traffic noise prediction model uses the number and type of vehicles on the planned roadway, their speeds, the physical chazacteristics of the road (curves, hills, depressed, elevated, etc.), receptor location and height, and, if applicable, barrier type, barrier ground elevation, and barrier top elevation. In this regazd, it is noted that only preliminary alignment was available for use in this noise analysis. The project proposes upgrading and safety improvements to SR 1323 (Riverview Street) and NC 28. This noise analysis evaluated three alternates, all consisting of upgrading and safety improvements to an existing two-lane facility. Only those existing natural or man-made barriers were included in setting up the model. The roadway sections and proposed intersections were assumed to be flat and at-grade. Thus, this analysis represents the "worst-case" topographical conditions. The noise predictions made in this report aze highway-related noise predictions for the traffic conditions during the year being analyzed. 42 Peak hour design and level-of-service (LOS) C volumes were compazed, and the volumes resulting in the noisiest conditions were used with the proposed posted speed limits. Hence, during all other time periods, the noise levels will be no greater than those indicated in this report. The TNM computer model was utilized in order to determine the number of land uses (by type) which would be impacted during the peak hour of the design year 2025. Aland use is considered impacted when exposed to noise levels approaching or exceeding the FHWA noise abatement criteria and/or predicted to sustain a substantial noise increase. e. Traffic Noise Impacts and Noise Contours Traffic noise impacts occur when the predicted traffic noise levels either: [a] approach or exceed the FHWA noise abatement criteria (with "approach" meaning within 1 dBA of the Table N2 (Appendix 2) value), or [b] substantially exceed the existing noise levels. The NCDOT definition of substantial increase is shown in the lower portion of Table N2 (Appendix 2). Consideration for noise abatement measures must be given to receptors that fall in either category. In accordance with NCDOT Traffic Noise Abatement Policy, the FederaUState governments are not responsible for providing noise abatement measures for new development which building permits are issued within the noise impact azea of a proposed highway after the Date of Public Knowledge. The Date of Public Knowledge of the location of a proposed highway project will be the approval date of CEs, FONSIs, RODS, or the Design Public Hearing, whichever comes later. For development occurring after this public knowledge date, local governing bodies aze responsible to insure that noise compatible designs are utilized along the proposed facility. The number of receptors in each activity category for each section predicted to become impacted by future traffic noise is shown in Table NS (Appendix 2). These aze noted in terms of those receptors expected to experience traffic noise impacts by either approaching or exceeding the FHWA NAC or by a substantial increase in exterior noise levels. Under Title 23 CFR Part 772, 2 residences and 1 business aze predicted to be impacted due to highway traffic noise in the project azea by the selection of Alternate 3. The impacts for each alternate can be found in Table NS (Appendix 2). The maximum extent of the 72-dBA noise level contour is less than 37.0 feet from the center of the proposed roadway. The maximum extent of the 67-dBA noise level contour is 62.7 feet from the center of the proposed roadway. Contour information in Table NS (Appendix 2) shows this contour information by section. This information should assist local authorities in exercising land use control over the remaining undeveloped lands adjacent to the roadway within local jurisdiction. For example, with the proper information on noise, the local authorities can prevent further development of incompatible activities and land uses with the predicted noise levels of an adjacent highway. Table N6 (Appendix 2) exhibits the exterior traffic noise level increases for the identified receptors by roadway section. There aze no substantial noise level impacts anticipated by this project by the selection of Alternate 3. The predicted noise level increases for this project range up to +5 dBA. The amount of substantial noise level impacts for each 43 alternate can be found in Table N6 (Appendix 2). When real-life noises aze heazd, it is possible bazely to detect noise level changes of 2-3 dBA. A 5-dBA change is more readily noticeable. f. Traffic Noise Abatement Measures If traffic noise impacts aze predicted, examination and evaluation of alternative noise abatement measures for reducing or eliminating the noise impacts must be considered. Consideration for noise abatement measures must be given to all impacted receptors. There aze impacted receptors due to highway traffic noise in the project azea. The following discussion addresses the applicability of these measures to the proposed project. 1). Highway Alignment Selection Highway alignment selection involves the horizontal or vertical orientation of the proposed improvements in such a way as to minimize impacts and costs. The selection of alternative alignments for noise abatement purposes must consider the balance between noise impacts and other engineering and environmental parameters. For noise abatement, horizontal alignment selection is primarily a matter of siting the roadway at a sufficient distance from noise sensitive azeas. Changing the highway alignment is not a viable alternative for noise abatement. 2). Traffic System Management Measures Traffic system management measures, which limit vehicle type, speed, volume and time of operations, are often effective noise abatement measures. For this project, traffic management measures are not considered appropriate for noise abatement due to their effect on the capacity and level-of-service of the proposed facility. Past project experience has shown that a reduction in the speed limit of 10 mph would result in a noise level reduction of approximately 1 to 2 dBA. Because most people cannot detect a noise reduction of up to 3 dBA and because reducing the speed limit would reduce roadway capacity, it is not considered a viable noise abatement measure. This and other traffic system management measures, including the prohibition of truck operations, aze not considered to be consistent with the project's objective of improving SR 1323 and NC 28. 3). Noise Barriers Physical measures to abate anticipated traffic noise levels aze often applied with a measurable degree of success on fully controlled facilities by the application of solid mass, attenuable measures strategically placed between the traffic sound source and the receptors to effectively diffract, absorb, and reflect highway traffic noise emissions. Solid mass, attenuable measures may include earth berms or artificial abatement walls. The project will maintain uncontrolled or limited control of access, meaning most commercial establishments and residents will have direct access connections to the proposed roadway, and all intersection will adjoin the project at grade. For a noise barrier to provide sufficient noise reduction it must be high enough and long enough to shield the receptor from significant sections of the highway. Access openings in the barrier 44 severely reduce the noise reduction provided by the barrier. It then becomes economically unreasonable to construct a barrier for a small noise reduction. Safety at access openings (driveways, crossing streets, etc.) due to restricted sight distance is also a concern. Furthermore, to provide a sufficient reduction, a barrier's length would normally be 8 times the distance from the barrier to the receptor. For example, a receptor located 50 feet from the barrier would normally require a barrier 400 feet long. An access opening of 40 feet (10 percent of the azea) would limit its noise reduction to approximately 4 dBA (FUNDAMENTAL AND ABATEMENT OF HIGHWAY TRAFFIC NOISE, Report No. FHWA-HHI-HEV-73-7976-1, USDOT, chapter 5, section 3.2, page 5-27). Hence, this type of control of access effectively eliminates the consideration of berms or noise walls as noise mitigation measures. In addition, businesses, churches, and other related establishments located along a particular highway normally require accessibility and high visibility. Solid mass, attenuable measures for traffic noise abatement would tend to disallow these two qualities, and thus, would not be acceptable abatement measures in this case. 4). Other Mitigation Measures Considered The acquisition of property in order to provide buffer zones to minimize noise impacts is not considered a feasible noise mitigation measure for this project. The cost to acquire impacted receptors for buffer zones would exceed the abatement threshold of $25,000 per benefited receptor. The use of buffer zones to minimize impacts to future sensitive areas is not recommended because this could be accomplished through land use control. The use of vegetation for noise mitigation is not considered reasonable for this project, due to the amount of substantial amount ofright-of--way necessary to make vegetative barriers effective. FHWA research has shown that a vegetative barrier should be approximately 100' wide to provide a 3-dBA reduction in noise levels. In order to provide a 5-dBA reduction, substantial amounts of additional right-of--way would be required. The cost of the additional right-of--way and plant sufficient vegetation is estimated to exceed the abatement threshold of $25,000 per benefited receptor. Noise insulation was also considered; however, no public or non-profit institutions were identified that would be impacted by this project. g. No-Build Alternative The traffic noise impacts for the No-Build alternative was also considered. If the proposed widening did not occur, 4 receptors are anticipated to approach or exceed the FHWA NAC. Also, the receptors could anticipate experiencing an increase in exterior noise levels of approximately 2 dBA. As previously noted, it is bazely possible to detect noise level changes of 2-3 dBA. A 5-dBA change in noise levels is more readily noticed. h. Construction Noise The major construction elements of this project are expected to be earth removal, hauling, grading, and paving. General construction noise impacts, such as temporary speech interference for passers-by and those individuals living or working neaz the 45 project, can be expected particulazly from paving operations and from the earth moving equipment during grading operations. However, considering the relatively short-term nature of construction noise and the limitation of construction to daytime hours, these impacts aze not expected to be substantial. The transmission loss chazacteristics of neazby natural elements and man-made structures aze believed to be sufficient to moderate the effects of intrusive construction noise. i. Noise Analysis Summary Traffic noise impacts aze an unavoidable consequence of transportation projects especially in azeas where there are not traffic noise sources. All traffic noise impacts were considered for noise mitigation. Based on these preliminary studies, traffic noise abatement is not recommended, and no noise abatement measures aze proposed. This evaluation completes the highway traffic noise requirements of Title 23 CFR Part 772, and unless a major project change develops, no additional noise reports will be submitted for this project. 9. Air Quality Analysis The project is located in Macon County, which has been determined to be in compliance with the National Ambient Air Quality Standazds. 40 CFR part 51 is not applicable, because the proposed project is located in an attainment area. This project is not anticipated to create any adverse effects on the air quality of this attainment area. If vegetation is disposed of by burning, all burning shall be done in accordance with applicable local laws and regulations of the North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic noise of Title 23 of the Code of Federal Regulations, Part 772, and for air quality of the 1990 Clean Air Act Amendments and the NEPA process, and no additional reports are necessary. 46 VI. COMMENTS AND COORDINATION A. Comments Received The project has been coordinated with appropriate federal and state agencies listed below. Written comments were received from agencies noted with an asterisk (*). These comments were considered during the preparation of this assessment. Appendix 3 contains copies of the comments received.

Citizens Informational Workshop An informal Citizens Informational Workshop for the project was held on June 21, 2001 at the Macon County Community Center. Representatives from NCDOT were available at the workshop to discuss the project with citizens and local officials. Approximately 30 people attended the workshop. Representatives from the Town of Franklin attended the workshop. C. Agency Coordination A Scoping Meeting was held for the project in Raleigh, on February 14, 2001. Based on the minimal anticipated impacts, it was decided that this project did not need to go through the NEPAlMerger process with the review agencies. It is anticipated that the project will not impact wetlands and that the stream impacts would be minimal such that a Nationwide Permit would apply. There were concerns about protected species in the Little Tennessee River and the project's impact on essential habitat; however, the general consensus was that these concerns could be addressed with the agencies on an individual basis along with other environmental impacts. Additionally, the bridge over the River will not be replaced under this project or any other project currently included in the Tranaportation Improvement Program. 47 D. Public Hearing A public hearing will be held for this project following the circulation of this document. At the hearing, more detailed information about the proposed improvements will be available for the public. The public will be invited to make comments or voice concerns regarding the proposed action. A final decision with regard to a preferred alternative will not be made until all public hearing comments are fully evaluated. 48 FIGURES Figure 1 Project Location Figure 2 Project Aerial Figure 3 E~sting Curve Design Speeds Figure 4 Typical Section Figure 5a 2002 Traffic Data Figure 5b 2002 Traffic Data Figure 6a 2025 Traffic Data Figure 6b 2025 Traffic Data Figure 7 Level of Service Figure 8 Alternate 1, 2, and 3 Curve Design Speed Figure 9a Intersection Lane Configurations Figure 9b Intersection Lane Configurations Figure 10 Thoroughfare Plan N RoS~ ~~~~ 28 ~~ D PROJECT UNITS - ~ a ~ , ~ ~ r 0 ."

Gilmore, P.E., Manager NCDOT, Project Development & Environmental Analysis Through: John Dorney, NC Division of Water Qua From: Cynthia F. Van Der Wiele, NCDOT Coordinator ~',t,'~t~ Subject: Scoping comments on the proposed improvements to NC 28 and SR 1323. SR 1323 (Riverview St.) from SR 1659 (TIP Project U-2929 Depot St. Ext.) in Franklin to NC 28, and NC 28, from SR 1323 (Riverview St.) to SR 1335 (Sanderstown Rd.), Macon County, Federal Aid Project No. STP-28(1), State Project No. 8.1970801, T.I.P. Project R-2408. This memo is in reference to your correspondence dated March 20, 2001 (received March 27, 2001), in which you requested scoping comments for the above project. The project will cross Jacob Branch, Crawford Branch and potentially impact Lake Emory, located in the Little Tennessee River Basin. These water bodies are classified as C waters. The NC Division of Water Quality requests that NCDOT consider the following environmental issues for the proposed project: A. NCDWQ prefers replacement of bridges with bridges. However, if the new structure is to be a culvert, it should be countersunk to allow unimpeded fish and other aquatic organisms passage through the crossing. Please be aware that floodplain culverts are required under Nationwide 14. B. The document should provide a detailed and itemized presentation of the proposed impacts to wetlands and streams with corresponding mapping. C. There should be a discussion on mitigation plans for unavoidable impacts. If mitigation is required, it is preferable to present a conceptual (if not finalized) mitigation plan with the environmental documentation. While the NCDWQ realizes that this may not always be practical, it should be noted that for projects requiring mitigation, appropriate mitigation plans will be required prior to issuance of a 401 Water Quality Certification. D. When practical, the DWQ requests that bridges be replaced on the existing location with road closure. If a detour proves necessary, remediation measures in accordance with the NCDWQ requirements for General 401 Certification 2726/Nationwide Permit No. 33 (Temporary Construction, Access and Dewatering) must be followed. Michael F. Easley Governor William G. Ross, Jr., Secretary Department of Environment and Natural Resources Kerr T. Stevens Division of Water Quality North Carolina Division of Water Quality, 401 Wetlands Certification Unit, 1650 Mail Service Center, Raleigh, NC 27699-1650 (Mailing Address) 2321 Crabtree Blvd., Raleigh, 3-2260 (Location) 919-733-1786 (phone), 919-7~ A3-5 ax), http://h2o.enr.state.nc.us/ncwetlands/ Page 2 of 2 E. If applicable, DOT should not install the bridge bents in the creek, to the maximum extent practicable. F. Wetland and stream impacts should be avoided (including sediment and erosion control structures/measures) to the maximum extent practical. If this is not possible, alternatives that minimize wetland impacts should be chosen. Mitigation for unavoidable impacts will be required by DWQ for impacts to wetlands in excess of one acre and/or to streams in excess of 1501inear feet. G. Borrow/waste areas should not be located in wetlands. It is likely that compensatory mitigation will be required if wetlands are impacted by waste or borrow. H. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is approved under General 401 Certification Number 3027/Nationwide Permit No. 6 for Survey Activities. I. In accordance with the NCDWQ Wetlands Rules { 15A NCAC 2H.0506(b)(6)}, mitigation will be required for impacts of greater than 1501inear feet to any single perennial stream. In the event that mitigation becomes required, the mitigation plan should be designed to replace appropriate lost functions and values. In accordance with the NCDWQ Wetlands Rules { 15A NCAC 2H.0506 (h)(3)},the Wetland Restoration Program may be available for use as stream mitigation. J. Sediment and erosion control measures should not be placed in wetlands. K. The 401 Water Quality Certification application will need to specifically address the proposed methods for storm water management. More specifically, storm water should not be permitted to discharge directly into the creek. Instead, storm water should be designed to dT-ain to a properly designed storm water detention facility/apparatus. L. While the use of National Wetland Inventory (NWI) maps and soil surveys is a useful office tool, their inherent inaccuracies require that qualified personnel perform onsite wetland delineations prior to permit approval. Thank you for requesting our input at this time. The DOT is reminded that issuance of a 401 Water Quality Certification requires that appropriate measures be instituted to ensure that water quality standards are met and designated uses are not degraded or lost.

Brook, Director ., March 9, 2004 MEMORANDUM TO: Matt Wilkerson, Archaeology Supervisor Project Development and Environmental Analysis Branch ; NCDOT Division of Highways FROM: David Brook ;~ ~~ 1 ~~ SUBJECT: Improvements to NC 28 and SR 1323, R-2408, Macon County; ER02-9378 Thank you for forwarding design plans for the three alternates for the above project. We have previously concurred with the recommendation for National Register eligibility under Criterion D for archaeological sites 31MA588 and 31MA589. Alternates 1 and 2 would have an adverse effect on 31MA588 and 31MA589. It is our understanding that Alternate 3 will confine ground disturbance to previously disturbed areas, that retaining walls at 31MA588 and 31MA589 ~~ill be placed along the existing cuts, and that non-destructive techniques will be used for placing fill on the east side of 31MA588. Therefore, Alternate 3, as proposed, would have no adverse effect on 31MA588 and 31 MA589. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

The occupants of the affected residences may qualify for aid under one or more of the NCDOT relocation programs. It is the policy of the NCDOT to ensure that comparable replacement housing will be available prior to construction of state and fedezally assisted projects. Furthermore, the North Carolina Board of Transportation has the following three programs to minimize the inconvenience of relocation: *Relocation Assistance, *Relocation Moving Payments, and *Relocation Replacement Housing Payments or Rent Supplement. With the Relocation Assistance Program, experienced NCDOT staff will be available to assist displacees with information such as availability and prices of homes, apartments, or businesses for sale or rent and financing or other housing programs. The Relocation Moving Payments Program, in general, provides for payment of actual moving expenses encountered in relocation. Where displacement will force an owner or tenant to purchase or rent property of higher cost or to lose a favorable financing arrangement (in cases of ownership), the Relocation Replacement Housing Payments or Rent Supplement Program will compensate up to $22,500 to owners who are eligible and qualify and up to $5,250 to tenants who are eligible and qualify. The relocation progamm for the proposed action will be conducted in accordance with the Federal Uniform Relocation Assistance and Real Property Acquisition Policies Act of 1970 (Public Law 91-646), and/or the North Carolina Relocation Assistance Act (GS-133- S through 133-18). The program is designed to provide assistance to displaced persons in relocating to a replacement site in which to live or do business. At least one relocation officer is assigned to each highway project for this purpose. The relocation officer will determine the needs of displaced families, individuals, businesses, non-profit organizations, and farm operations for relocation assistance advisory services without regard to race, color, religion, sex, or national origin. The NCDOT will schedule its work to allow ample time, prior to displacement, for negotiations and possession of replacement housing which meets decent, safe, and sanitary standards. The displacees are given at least a 90-day written notice after NCDOT purchases the property. Relocation of displaced persons will be offered in areas not generally less desirable in regard to public utilities and commercial facilities. Rent and sale prices of replacement property will be within the financial means of the families and individuals displaced and will be reasonably accessible to their places of employment. The relocation officer will also assist owners of displaced businesses, non-profit organizations, and farm operations in searching for and moving to replacement property. All tenant and owner residential occupants who may be displaced will receive an explanation regarding all available options, such as (1) purchase of replacement housing, (2) rental of replacement housing, either private or public, or (3) moving existing owner- occupanthousing to another site (if possible). The relocation officer will also supply A4-1 information concerning other state or federal programs offering assistance to displaced ' persons and will provide other advisory services as needed in order to minimize hardships to displaced persons in adjusting to a new location. The Moving Expense Payments Program is designed to compensate the displacee for the costs of moving personal property from homes, businesses, non-profit organizations, and farm operations acquired for a highway project. Under the Replacement Program for Owners, NCDOT will participate in reasonable incidental purchase payments for replacement dwellings such as attorney's fees, surveys, appraisals, and other closing costs and, if applicable, make a payment for any increased interest expenses for replacement dwellings. Reimbursement to owner-occupants for replacement housing payments, increased interest payments, and incidental purchase expenses may not exceed $22,500 (combined total), except under the Last Resort Housing provision. A displaced tenant may be eligible to receive a payment, not to exceed $5,250, to rent a replacement dwelling or to make a down payment, including incidental expenses, on the purchase of a replacement dwelling. The down payment is based upon what the state determines is required when the rent supplement exceeds $5,250. It is a policy of the state that no person will be displaced by the NCDOT's state or federally-assisted construction projects unless and until comparable replacement housing has been offered or provided for each displacee within a reasonable period of time prior to displacement. No relocation payment received will be considered as income for the purposes of the Internal Revenue Code of 1954 or for the purposes of determining eligibility or the extent of eligibility of any person for assistance under the Social Security Act or any other federal law. Last Resort Housing is a program used when comparable replacement housing is not available, or when it is unavailable within the displacee's financial means, and the replacement payment exceeds the federal/state legal limitation. The purpose of the program is to allow broad latitudes in methods of implementation by the state so that decent, safe, and sanitary replacement housing can be provided.
