Signature Date � Registration No. • As-Built Report for the Greene Mitigation Site on Goose Creek, Mecklenburg County Prepared for the North Carolina Department of Transportation Stream Mitigation Program Transportation Improvement Project R-2420B � Joseph H. Mickey, Jr. James A. Wasseen II North Carolina Wildlife Resources Commission Division of Inland Fisheries 2005 � • This as-built report is submitted as partial fulfillment of the off-site stream mitigation agreement between the North Carolina Department of Transportation (DOT) and North Carolina Wildlife Resources Commission (WRC) for the R-2420 B road improvement project in Mecklenburg County. Under this agreement, a total of 903 linear feet of stream mitigation is required by the United States Army Corps of Engineers (USACE) and the North Carolina Division of Water Quality (DWQ). The purpose of this report is to summarize those practices used for bank stabilization and habitat enhancement along 783 linear feet of Goose Creek known as the Greene mitigation site, Mecklenburg County (Figure 1). Mickey and Scott (2003) described pre-construction site conditions and project objectives. Mussel surveys The Carolina heelsplitter Lasmigona decorata, a federally endangered freshwater mussel, is found in Goose Creek. Approximately 4.5 miles of Goose Creek have been designated as critical habitat for this species. This area extends from the NC 218 bridge in Union County to its confluence with the Rocky River. The Greene mitigation site is located several miles upstream of the designated critical habitat area. To ensure that the Carolina heelsplitter was not present at the Greene mitigation site, a mussel survey was conducted on March 18, 2004 by the Catena Group using batiscopes and tactile surveys along the banks (Savidge 2004). The Carolina heelsplitter was not found at the site, however, one individual of the Carolina creekshell Villosa vaughaniana (Federal species of concern and North Carolina endangered species) was found upstream of Country Woods Drive, outside of the mitigation site impact area (Savidge 2004). • An USACE permit condition also required the WRC to conduct a mussel survey at the site immediately before construction started. Any mussels found at this time or during construction would be relocated upstream of the construction area. On January 10, 2005, WRC nongame aqua.tic biologists conducted a mussel search. No live mussels were found; however, one Carolina creekshell shell was located and moved. During construction, no mussels or mussel shells were observed. Conservation Easement and Land Purchases In order to ensure long term protection of the site, NCDOT obtained a 50 ft buffer conservation easement (CE) totaling 0.47 acres from James and Christy Tyndal, and purchased 1.58 acres from Lisa Gabbazd and 3.71 acres from George and Linda Greene (Figure 2). Riparian buffer widths range from 100 ft to >300 ft along the purchased properties. The CE and land purchases permanently protect 5.75 acres and encompass 783 lineaz ft of Goose Creek. Right-of-way access to the site is from Country Woods Drive (SR 4220), which borders the northern end of the site. The site will be maintained by the WRC in perpetuity. Site Improvements Channel Modifications Construction was carried out through an informal contract with Todd Hodges Construction of • Patterson, N.C. The contractor provided a dump truck, loader, and trackhoe with hydraulic • thumb. Access to the site was through a temporary construction access along an old road bed off Country Woods Drive. Before the contractor could move to the site, the local DOT maintenance shop had to remove a guard rail and install one 12 inch and two 36 inch corrugated metal culverts in ephemeral stream channels to allow site access. Gravel and ballast stone were then placed over the pipes and on the temporary access road. Stream work began on February 8 and was completed on February 23, 2005. Six rock vanes, two rock toe benches, three root wad structures, and four log structures were installed to prevent channel headcutting, to divert flows away from streambanks, and to create or maintain pool habitat (Table 1, Appendix 1). Large footer rocks were installed to support top boulders in the vanes. Large boulders were also placed behind root wad structures and used as log structure anchors. Holes were dug below the vanes and root wads to hasten and maintain pool formation. Excess streambed materials were excavated at rock vanes and placed upstream of the structure neaz the bank where natural deposition would be expected. Rock vanes were used to divert water away from eroding banks and for habitat diversity. In addition to these structures, several existing large boulders were repositioned to direct flows away from streamba.nks. At seven locations totaling 6751inear feet, streambanks were reshaped on a 1:1 or 2:1 slope to eliminate vertical, eroding banks (Table 1, Appendix 1). At six of the bank sites a bankfull bench was constructed and the bank reshaped on a 1:1 or 2:1 slope (Table 1, Appendix 1). By the end of each working day, all disturbed soils were seeded, limed and fertilized, and covered with erosion control matting or with straw. • The as-built survey, conducted on March 2, 3 and 14, 2005, included a longitudinal profile, eight channel cross-sections, pebble counts, and establishment of vegetation monitoring plots. The purpose of the as-built survey is to establish post-construction baselme data that can be compared with future surveys to monitor channel stability and vegetation survival. A water level staff gage is located in the lower right corner (facing downstream) of the multi-cell box culvert at station 0+00. The water level at the time of the as-built survey was 0.18 ft. The pre-construction longitudinal survey was 773 ft in length whereas the as-built survey began at station 1+10 and ended at station 7+78, a total of 668 ft(Figure 3). The as-built survey did not include the first 109 ft of the project site since no stream work occurred in this section. The pre-construction survey found 49% of the stream was pool habitat whereas the as-built survey contained 37% pool habitat. The reason for the decrease in pool habitat between the two surveys is directly related to two factors. First, the pre-construction survey identified a long shallow pool from stations 3+52 — 4+60 whereas the as-built survey found a pool — riffle — run — pool complex at the same stations. Second, the pre-construction survey contained a long pool that had developed behind a large log/debris jam (Figure 3) from stations 4+82 — 5+68. This log/debris jam is no longer present and the as built survey identified a pool — riffle — pool — riffle — pool — run complex at these same stations. There is a rapid rise in the thalweg at the head of a riffle at station 6+24(Figure 3). This 0.5 ft rise is attributed to the presence of bedrock located in the pool above this station. Eight cross-sections were established for the as-built survey (Figure 4). Two cross-sections were located at pools (Figures 4.5, 4.6) and six at riffles (Figures 4.1, 4.2, 4.3, 4.4, 4.7, and 4.8). • Data from the six riffle cross-sections was used to determine the stream type following 2 • construction (Table 2). The pre-construction survey (Mickey and Scott 2003) classified the stream at the Crreene site as an unstable F4 and G4 stream type (Rosgen 1996). Using the North Carolina rural regional curve data (RRC) (Hannan 1999), the as-built survey classified the constructed stream reach as a stable F4 at two locations and a B4c at the other four locations (Table 2). The project goal to construct a stable F4 and C4 channel through this reach was achieved. However, when comparing the same six riffle cross-sections to the North Carolina urban regional curve data (LTRC) (Doll et al. 2002), four of the six cross-sections are C4 and two are slightly entrenched E4 stream types (Table 3). The reason for using the RRC and URC is that the present condition of the stream channel alludes to the stream's stable F4 and B4c conditions evolving in an urban setting to stable C4 and E4 channels. The Goose Creek watershed contains approximately 10% impervious area (M. Fowlkes, personal communication). With the completion of the I-485 project, the area is ra,pidly transforming from a rural to urban landscape. The C4 and E4 channels are more representative of the newly constructed channel cross-sections (Figure 4). Channel bed material was analyzed using the reachwide pebble count and cross-section survey methods (NCSRI 2003). Riffle pebble counts were conducted in the vicinity of cross- section stations 1+39 and 6+24. The D5� observed in the two riffles and reach ranged from 11.7 mm to 25.4 mm with a weighted dso of 18.4 mm (Figure 5). Sixty-four percent of the bed material in this reach of Goose Creek is considered gravel, 17 % silt and sand, and 16 % cobble (Figure 5). • Riparian Improvements Disturbed streambanks and soil disposal areas were seeded with a WRC native riparian mix (Mickey and Hining 2003) and a cover crop of winter wheat and rye. After seeding, bare soils were limed, fertilized, and covered with erosion control blankets or with straw. Erosion control blankets were used to stabilize the soil surface on steep slopes until vegetation can become established. A total of 981 stems (live stakes and rooted trees) were planted during and following construction (Table 4). Sixty-four percent of the planted stems were composed of silky dogwood Cornus amomum (28%) and silky willow Salix sericea (36%). Three vegetation plots totaling 0.085 acres and 195 stems (20% of total planted) were established on March 3, 2005 (Table 5, Appendix 2). These three plots will be used to determine stem survival rates through the monitoring period. The vegetation plots can also be used to monitor volunteer stem growth. Based on planting guidelines established for mitigation sites, a total of 320 stems/acre should be counted through year three (LTSACE 2003). At the Greene site, approximately 0.8 acres were disturbed during construction, requiring that 256 stems be counted at the site in the winter of 2008. The terrestrial exotic invasive plants of wild olive Elaeagnus spp. and Chinese privet Ligustrum sinense exist at the site. These invasive species need to be monitored and if they become a nuisance, some form of cutting/chemical control may be required. u • Project Costs The WRC project cost for stream enhancement work was $30, 454.17 or $ 38.89 per lineaz foot of stream enhancement (Table 6). Project cost includes: meetings with landowners, DOT, DWQ, and U.S. Fish and Wildlife Service personnel; field survey work; preparation of project conceptual design; construction and as-built report; tree purchase and planting; erosion control materials (seed, fertilizer, fabric); and WRC personnel and administrative costs. Taking into account DOT personnel, equipment, materials expenses, and CE and land purchase costs, project costs increase to $101,871.36 or $131.79 per foot (Table 6). Site monitoring and repair costs will be added to the cost total as they accrue during the monitoring period. Summary Using natural stream design techniques, stream dimension and profile was improved at this site. Based on North Carolina RRC data (Harmon et al. 1999), an unstable F4 and G4 stream type was converted to a stable F4, B4c stream type. However, when taking into account that the watershed is rapidly urbanizing, North Carolina URC data (Doll et al. 2002), indicate this reach of Goose Creek would be classified as a C4 and slightly entrenched E4 stream type. Water quality will be improved through reduced sedimentation from previously eroding banks. In- stream habitat for fish and aquatic invertebrates has been increased with the installation of rock vanes, log vanes, and root wads. Both aquatic and terrestrial species will benefit with the return of a functioning riparian corridor. Stream aesthetics have also been improved. Trends in pool • development and channel narrowing tend to be positive from pre-construction to as-built conditions. However, monitoring will be necessary to determine if the scour action created by rock vanes, log vanes, and root wads can be maintasned or increased. The reshaped banks should remain stable following bankfull and flood events. • 4 CJ References Doll, Barbara A., D. E. Wise-Fredrick, C. M. Buckner, S. D. Wilkerson, W. A. Harman, R. E. Smith, and J.

Mitigation Site on Meat Camp Creek, Watauga County Prepared for the North Carolina Department of Transportation Stream Mitigation Program Transportation Improvement Project R-529 Joseph H. Mickey, Jr. Staci S. Hining North Carolina Wildlife Resources Commission Division of Inland Fisheries December 2003 This 2003 monitoring report is submitted as partial fulfillment of the off-site stream mitigation agreement between the North Carolina Department of Transportation (DOT) and North Carolina Wildlife Resources Commission (WRC) for the R-529 US 421 road improvement project in Watuaga County. Under this agreement, a total of 14,8141inear feet of stream mitigation is required by the United States Army Corps of Engineers (COE) and 7,407 linear feet of mitigation is required by the North Carolina Division of Water Quality (DWQ)- The purpose of this report is to summarize the 2003 monitoring data collected from 6521inear feet of Meat Camp Creek located on the Miller et al. Property, Watauga County (Figure 1). Mickey and Scott (2002) described pre-construction survey methods, site conditions, and project objectives. Monitoring data was compared with data submitted in the 2003 as-built report (Mickey and Hining 2003). Site Improvements Channel Mod�cations The first year monitoring survey was completed on October 21, 2003 and included longitudinal profile, pebble count, and five channel cross-sections. The longitudinal profile has remained stable since the as-built survey (Figure 2). A total of 14 structures (2 rock weirs, 11 rock vanes and one log vane) were constructed (Table 1) with approximate locations shown on the longitudinal profile (Figure 2). The pre-construction and post construction riffle D-50's were 45 mm and 46.6 mm (coarse gravel) (Mickey and Hining 2003), respectively. The monitoring pebble count D-50 was 37.2 mm (Figure 3)_ While the monitoring D-50 was slightly smaller than the post and as-built D-50, it is still in the coarse gravel range. The five cross-sections have remained stable since construction and have experienced very little change since the as-built survey (Figures 4.1-4.5). Riparian Improvements A total of 177 live stakes and bare root nursery trees were planted on March 17, 2003 (Table 2). Plantings included tag alder Alnus serrulata, silky dogwood Cornus amomum, silky willow Salix sericea, black walnut Juglans nigra, and black locust Robirur pseudoacacia . Due to the small size of the plantings and high weed growth at the time of the monitoring survey, a survival count of live stakes and bare root nursery stock was not conducted. A vegetation count will be conducted during March of 2004. Livestock Exclusion The livestock exclusion plan, two water tanks and fencing, is functioning as planned. Livestock are no longer drinking from Meat Camp Creek or two small spring seeps located on the Miller property. Conclusion Since construction in September 2002, the Meat Camp Creek mitigation site has remained stable. Rock weirs, rock and log vanes are functioning as planned and have created more stable 2 streambanks at this location. Water quality should be improved through reduced sedimentation from eroding streambanks and exclusion of livestock from the riparian zone. In-stream habitat for fish and aquatic invertebrates has been increased with the installation of rock weirs, rock and log vanes and root wads. The second year of monitoring will be conducted during October/November 2004. References Mickey, 7. H. and S. S. Hining. 2003. As-built report for the Meat Camp Creek mitigation site, Watuaga County.

Watauga County is located in the northwest portion of North Carolina within the Blue Ridge Mountains. Boone is located within Watauga County and serves as the seat of County Government. It is the only municipality in the county with a population greater than 500. The action consists of the improvement of US 421 from the intersection of US 421/NC 194 within the Town of Boone to just west of the South Fork New River in Watauga County. The general location of the action is shown on Exhibit l.l. The proposed US 421 improvement will be a five-lane facilit� with an approximate length of one mile. This report docum2nts the ideritification of five possible construction alternatives. Three of these alternatives, as well as the "no-build" alternative, are evaluated with respect to feasibility, cost, environmental impact, and mitigation. US 421 serv�s as the primary transportation route linking Boone to eastern North Carolina. Over the past 20 years, this area has experienced a substantial increase in traffic volumes. This increase can be attributed largely to the popularity of the area as a tourist attraction. Each year, thousands of visitors from i the piedmont and coastal regions of the state travel to the Blue Ridge Mountains to view "the changing of the leaves," enjoy the many theme parks, or ski. The eastern section of Boone and the surrounding area are rapidly being developed. Several proposed commercial service areas just west of the South Fork New River Bridge are currently in the planning stages. Year 2008 traffic studies indicate the need for a multi-lane facility to accommodate these developments. The existing US 421 cannot" effectively serve this demand. The improvement of this roadway will ensure that adequate trans- portation facilities are available to accommodate anticipated future growth patterns. S.2 DESCRIPTION OF ALTERNATIVES The "no-build" alternative and five construction alternatives were evaluated for this report. The alternatives considered are shown in Exhibit 2.1 and are as follows: Alternative A- begins- at NC 194 and extends northeast around Mount Lawn Memorial Cemetery following along the alignment of SR 1329 (Perkinsville Drive) to connect with existing US 421 west of SR 1516. Alternative B- begins at the intersection of US 421 and NC 194 and extends southeasterly along Spruce Street to connect with US 421 just west of the South Fork New River Bridge. ii Alternative C- begins at NC 194 and extends southeasterly just north of Spruce Street to connect with US 421 just west of the South Fork New River Bridge. Alternative D- begins at NC 194 and follows existing alignment to the South Fork New River Bridge. Existing pavement would be maintained and widened. Alternative E- begins at NC 194 and follows the existing alignment to the South Fork New River Bridge. Existing pavement would be removed at designated points and the grades lowered or raised as required in order to maintain a 55-mph design speed. S.3 ALTERNATIVES CONSIDERED FOR DETAILED STUDY Alternatives A, B, and E were selected for detailed evaluation based on environmental impacts, land use compatibility, and constructability. Functional design plans and profiles were prepared for each of the study alternatives and served as the basis for the cost-benefit analysis. S.4 ENVIRONMENTAL IMPACTS The significant impacts and cost estimates evaluated for each alternative ate itemized in Table 5.1. iii TABLE S.1 EI�TVIRONMENTAL IMPACTS Alternative "No-Build" A B E Relocation Homes Businesses Graves Construction Cost Right-of-Way Cost Archaeological Sites Historical Sites Wetlands (Acres) Endangered Species Air Quality Violation Sites Noise Sites Prime Farmland (Acres) -- 10 23 24 -- 3 6 4 -- 0 0 100+ -- $3,853,000 $4,553,000 $2,603,000 -- 2,002,500 2,783,000 5,082,000 0 0 0 0 0 0 0 0 29 0 0 0 0 0 0 0 0 0 0 0 0 0 27 15 21 4 4 1 iv S.5 PERMITS REQUIRED No applicable state or federal permits are required. S.6 PREFERRED ALTERNATIVE Although the final selection of an alternative will not be made until after comments from the public hearing have been considered, the obvious advantages of Alternative A resulted in its identification as the preferred alternative. The advantages of Alternative A are as follows: l. It satisfies the need for an improved transportation facility. 2. The location is supported by most local residents and property owners. 3. The associated right-of-way and construction costs are minimized. 4. The fewest relocations of residences and businesses are required. u 0 ' ' ' Chapter TABLE OF CONTENTS Page Summary........................................... i Tableof Contents

County and to provide for their planned development. This study.substantiates the need for improving US 421 through an evaluation of the traffic demand and the transportation system within the study area. 1.1 PROJECT SETTING ' The Town of Boone is located in Watauga County in the northwestern portion of North Carolina. Watauga County is ' located within the scenic Blue Ridge Mountains which form part of the Southern Appalachian Mountain Range. Exhibit l.l shows the ' county and study area in relation to the state. � � ' ' ' The town's location allows for a variety of employment opportunities supported by the tourist trade and the winter skiing r�sorts. The population of Boone tripled in the twenty-five years between 1960 and 1985, growing from 3,686 to 11,360. Much of this growth can be attributed to the economic opportunities provided by tourism. ' Appalachian State University (ASU), founded in 1899, also has been a catalyst for Boone's growth. ASU's student population has ' � ' 1-1 almost quadrupled in the twenty-five years between 1960 and 1985, growing from 2,584 to 10,204. 1.2 SOCIAL AND ECONOMIC DEVELOPMENT US 421 is the only east-west roadway with direct access to the Boone area. During the past several decades, the traffic volumes on this highway have increased dramatically. The level of operation and safety of US 421 have been compromised by this increase, which was generated largely by summer tourism, part- time residents, university students, and winter ski resort enthusiasts. These traffic generators are a vital part of the economy of the region and crucial to the future well being of its citizens. During the past ten years, the county has seen its employment base shift from manufacturing and industrial to service and tourism. One reason for this loss of industry is the unsafe, limited, two-lane access provided by US 421. 1.3 TRANSPORTATION DEMAND 1.3.1 Existing Year 1988 and Design Year 2008 No-Build Traffic Volumes Average daily traffic (ADT) volumes for Years 1988 and 2008 on US 421 and NC 194 are shown in Exhibit 1.2. The highest volume within the study limits, 13,600 and 24,600 vehicles per day (vpd) for Years 1988 and 2008 respectively, occurs on US 421 east of the intersection with NC 194. 1-2 , ' ' , , , ' �� ' , � .

As indicated, US 421 is now operating at LOS E. It is expected to operate at LOS F in design year 2008. LOS E describes high driver discomfort, with delays being experienced greater than 75 percent of the time. The intersection of US 421/NC 194 is operating at LOS F during peak hour. At LOS F, excessive delay and queuing of traffic are experienced. 1.3.2 Accidents Accident data for the period between January l, 1985, and March 31, 1988, were gathered for the study area. During this three years and four months time span, a total of 24 accidents, all non-fatal, occurred at the US 421/NC 194 intersection. Based on the total number of vehicles entering the intersection, the total accident rate equates to 105.36� accidents per 100 million entering vehicles (MEV). This is considerably higher than the national average of 82- accidents per 100 MEV for T intersections as reported by the Federal Highway Administration (FHWA).1 The predominant cause of this abnormally high average accident rate is the over-capacitation of the intersection. The total number of vehicles entering the intersection in Design Year 2008 is projected to be approximately 38,700 per day. Assuming that the total accident rate will not increase, the total number of accidents that would occur in Year 2008 is approximately 12. 1-4 ' � Between the intersection and the South Fork New River Bridge, a ' total of 10 accidents occurred during the study period. This equals a total accident rate of 148.10 accidents per 100 million ' vehicle miles traveled (MVM). Using the anticipated Design Year 2008 traffic projections for this segment of roadway, the total ' number of accidents would be approximately 23 in Year 2008. ' 1.4 SUMMARY , Because US 421 is the only highway connecting Boone to eastern North Carolina, the healthy growth of this area would be ` constrained by the capacity limitations and safety concerns of ' the existing highway. � � ' ' ' , , ' � ' 1-5 1.

During the data gathering and analysis phase, three of the five construction alternatives were ' selected for detailed study. The following is a description of the preliminary alignment alternatives and the process for their ' development and rejection or selection for further study. ' � ' � ' � ' ' ' ' ' ' 2.1 NO-BUILD ALTERNATIVE The No-Build or "do nothing" Alternative is used as a baseline condition with which to compare all other acceptable alternatives. Under the "no build" scenario, no major improvements would be made to the existing US 421 roadway. Advantages of the "do nothing" Alternative include the following: - No new capital expenditure. - No relocation of businesses or houses. - No traffic delay due to construction. - No removal of or impact on the biotic communities. - No increase in ambient noise levels. However, there are a significant number of disadvantages to the No-Build Alternative: - Rapid degeneration of the Level of Service. - Increased demand on local roads. 2-1 - Increased amount and duration of congestion. - Higher-than-average number of accidents. 2.2 CONSTRUCTION ALTERNATIVES Accommodating the area's future traffic demands will require increasing the capacity of US 421. This can be done by constructing two additional lanes in the existing US 421 corridor or by using alternative alignment corridors. Preliminary Alternative Corridors A through C were developed using information collected about environmental, land use, and constructionability factors in the area. These alternatives are shown in Exhibit 2.1 and were presented for public review at the first public meeting/workshop held on January 17, 1989. The preliminary alternatives were then.more specifically analyzed according to the factors listed in Table 2.1. An evaluation matrix was used to identify and reject the alternatives that would provide the fewest benefits and have the greatest negative environmental impacts. . The basic evaluation methodology used to compare the corridor alternatives is described in Section 2.3. Using this process, Alternatives C and D were eliminated. The remaining corridor segments were studied in greater detail. 2.2.1 Alternative A Alternative A begins at NC 194 and extends northeast around Mount Lawn Memorial Cemetery following the alignment of SR 1329 2-2 , 1 � � , , � � � ' � ' ' � � ' ' � � TABLE 2.1 PRELIMINARY CONSTRUCTION ALTERNATIVES MATRIX CATEGORIES Category Factors Environmental Agricultural Resources Flood Plains Acreage Historical Sites Archaeological Sites Aesthetics Land Use Compatibility Neighborhoods Cemeteries Schools Churches Constructability Relocations Earthwork Traffic Control During Construction 2-3 (Perkinsville Drive) and connects with existing US 421 west of SR 1516. At-grade intersections are proposed at the western terminus of Alternative A with NC 194 and near the eastern terminus where this alternative meets existing US 421. Exhibit 2.2 shows the proposed intersections for all alternatives. 2.2.2 Alternative B Alternative B begins at the intersection of US 421 and NC 194 and extends southeasterly along Spruce Street to connect with US 421 just west of the South Fork New River Bridge. One at-grade intersection with NC 194 is proposed. Two are proposed on existing US 421, where Alternative B intersects both its western and eastern ends. 2.2.3 Alternative E Alternative E begins at NC 194 and follows the existing alignment to the South Fork New River Bridge. This alternative would improve the existing corridor while incorporating a 55-mph design speed. Although the construction cost to improve the existing corridor would be less than building on a new corridor, the cost of traffic control would be much greater. The only possible detour would be SR 1329, which has inadequate design and capacity for the large amount of traffic which would have to be detoured from US 421. 2-4 The existing vertical alignment does not provide sufficient sight distance to meet the proposed 55-mph design speed. One example of the vertical alignment deficiency is at the roadway's crest, approximately midway through the project. To correct this problem, the vertical curve would need to be lengthened, thus lowering the roadbed at its crest by over 25 feet. 2.2.4 Opening and Design Year Traffic Projections An assumed opening year of 1993 and design year of 2008 were established; the actual opening year would depend on a construction timetable. Exhibits 2.3 and 2.4 present the estimated ADT volumes for each alternative corridor alignment and the intersecting local roads for Opening Year 1993 and Design Year 2008, respectively. The estimated ADT volumes for Alternative E for.Years 1993 and 2008, respectively, are the same as those shown in Exhibit 1.2 for the No-Build Alternative. Exhibits 2.3 and 2.4 show that traffic volumes are approximately the same for Alternatives A and B. Traffic projections for existing US 421 would drop significantly, with only local traffic using the roadway. For both alternatives, ADT volumes are estimated at approximately 13,600 and 24,600 vpd for Years 1993 and 2008, respectively. 2-5 2.2.5 Roadway Design Criteria Roadway design criteria as approved by NCDOT and FHWA are shown in Table 2.2. These criteria, which are based on Year 2008 traffic projections, indicate that a minimum of five lanes--two- in each direction with a center turning lane--are needed for the mainline of US 421. Two typical sections are proposed for all alternatives, as shown in Exhibit 2.5. The use and location of the typical sections were determined by topographical consider- ations and transverse slopes. Typical Section 1 would be used from the western terminus where US 421 and NC 194 intersect to the point where the transverse slope exceeds 0.04. Typical Section 1 would then transition to Typical Section 2. 2.3 MATRIX EVALUATION OF SECTION ALIGNMENTS An evaluation matrix was used to compare the alternatives. The methodology is similar to that used to eliminate the least beneficial corridor alignment, although more comprehensive. The four major categories are environmental, land use compatibility, costs, and traffic services, and each has its own separate matrix evaluation. 2.3.1 Environmental Categor This category contains seven factors for evaluation: * Surface Water Impacts - the calculated effect on surface water quality; 2-6 TABLE 2.2 ROADWAY DESIGN CRITERIA Design Factors Recommended Standards Speeds *Mainline - 60 mph desirable, 55 mph minimum *Cross Streets - 35 mph Pavement Widths *Mainline - 12 feet standard lane width *Cross Streets - 11 feet minimum desirable Shoulder Widths *Mainline five-lane undivided (Typical Section 2) 10 feet outside (2 feet paved), *Mainline five-lane undivided (Typical Section 1) Use curb and gutter. Vertical *Mainline rates of grade - maximum 7% at 50 mph Alignment - maximum 6o at 60 mph *Stopping sight distance - 1984 AASHTO standards *Length of crest and sag vertical curves - 1984 AASHTO standards Horizontal *Degree of curvature: Alignment Mainline - 4°45' maximum (60 mph), 7°30' (50 mph) *Tangents mid-length between reversed curves should be adequate to facilitate superelevation transition. Cross Slopes *Mainline - normal crown *Superelevation - 0.08 maximum - 0.04 maximum with curb and gutter Vertical *At-grade intersections , Clearances Sources: "A Policy on Design of Highways and Streets�" AASHTO, 1984, and NCDOT Roadway Design Manual. 2-7 * Agricultural - the acreage of prime and/or important farmland within the right-of-way; * Historical Sites - the number of potentially eligible struc- tures within the right-of-way and the number of potentially eligible structures abutting the right-of-way; * Archaeological Sites - the number of significant sites within the right-of-way; * Flora/Fauna - the acreage of natural wildlife habitat and the number of potentially threatened or endangered species areas within the right-of-way; * Ground Water - the calculated effect on ground water quality; and * Hazardous Waste or Petroleum Storage Sites - the number of identified or potential hazardous waste sites located within the right-of-way. The Environmental category evaluation matrix is shown in Table 2.3 along with the scale for each of the seven factors. The higher the number of the scale, the greater the impact. For example, a high number on the Historical Sites factor scale means that a great number of historical sites are located within or adjacent to the right-of-way. Generally, Alternative E has the fewest negative impacts for all factors except Hazardous Waste or Petroleum Storage Sites. Alter- native A has the fewest possible hazardous waste or petroleum storage sites and falls within the two extremes for surface water 2-8 � Z � O � � X W , � � � �d � � \ � LL.

Alternative B has the most negative surface water and ground water impacts and ties with Alternative E for the number of potential hazardous waste sites. 2.3.2 Land Use Compatibility Category This category contains five factors for evaluation: * Parks - the number of parks that are impacted by noise; * Schools - the number of schools that are impacted by noise; * Churches - the number of churches that are impacted by noise; * Cemeteries - the number of actively visited cemeteries impacted by noise; * Subdivisions/Neighborhoods - the number of housing units approaching a noise level of 67 dBA plus the number of units having increased noise levels above existing ambient con- ditions of 15 dBA or more; and * Commercial - the number of commercial sites, including government facilities, approaching a noise level of 72 dBA plus the number of units having increased noise levels above existing ambient conditions of 15 dBA or more. The Land Use category evaluation matrix is shown in Table 2.4. The number of sites experiencing negative noise impacts for each alternative are as indicated. 2-10 TABLE 2.4 MATRIX EVALUATION OF THE LAND USE CATEGORY Factors Parks Schools Churches Cemeteries Subdivisions/ Neighborhoods Commercial * No Sites Located Alternative A * * 1 * 22 � 2-11 Alternative B * * * * 10 5 Alternative E * * 1 1 12 7 Alternative B follows an undeveloped corridor throughout much of its eastern half and so has the fewest negative noise impacts. Alternative A includes the greatest number of residences that experience a negative noise impact, but is tied with Alternative B for the fewest number of commercial sites. As discussed in Section 4.5.1 of this report, the majority of the sites identified in Table 2.4 as approaching undesirable noise levels are also impacted by noise under the No-Build Alternative. In some instances, the construction alternative even results in a reduction in the predicted noise levels. 2.3.3 Costs Category This category contains five factors for evaluation: * Construction - the estimated cost of the roadway, inter- sections with local streets, bridges, culverts, drainage, and earthwork; * Relocation - the estimated cost of business and residential relocations; * Right-of-Way - the estimated cost of right-of-way acquisition; and * Utilities - the estimated cost of utility relocation. * Total Costs - the summation of all costs. The Costs category evaluation matrix is shown in Table 2.5. All alternatives are ranked from the most expensive at 3 to the least 2-12 Factors Construction Relocation Right-of-Way Utilities Total Cost TABLE 2.5 MATRIX EVALUATION OF THE COSTS CATEGORY Scale Range 1-3 1-3 1-3 1-3 1-3 Alternative A 2 1 1 2 1 2-13 Alternative B 3 2 2 1 2 Alternative E 1 3 3 3 3 expensive at 1. The scale was derived from construction costs estimated as shown in Table 2.9. Alternative A has the least total cost, followed by Alternative B, with Alternative E having the greatest total cost. 2.3.4 Traffic Services Category This category involves the analysis of intersection LOS as shown in Table 2.6. If an unsignalized intersection would operate acceptably for the assumed Opening Year 1993 or Design Year 2008, it was so designated. If not, a signalized intersection analysis was performed to determine the LOS at which the signalized intersection would operate. The LOS analysis follows the methodology outlined in the 1985 Highway Capacity Manual (see Appendix A). Table 2.7 shows the expected average running speed for each alternative during peak and off-peak hours. Both Tables 2.6 and 2.7 show that all of the alternatives will operate at a vastly improved and acceptable LOS. 2.3.5 Safety Based on accident data gathered for existing US 421, accident rates and average annual accidents were calculated for the No-Build Alternative for Opening Year 1993 and Design Year 2008. Average annual accidents were also calculated for each of the other alternatives using accident rates provided by FHWA.1 The results are shown in Table 2.8. 2-14 � H � � a z'a � N W O f�A H H W � W H z H U W � v o0 0 �o a •� o J-1 N C/� ro� � [m � dl U v rn +� � � � o ... � ao v � N co O �o a •� o 1J N CI� ro� � C M S.+ dl U N 61 J� r-I V� � O � U � � vm O �o a •�+ o J-1 N f!� b� � L�i dMl U �-�+ � O � a � Cz.� � �o °a �--I O •rl N d� fA M \ dl C� orn z � v� 0 a � w 0 c � O •rt •�-+ 3 � � N Ul �f' �, � � c H � I I i � i i i � i i i I i � � i i � � I I � � � � i � � � I � \ I I 1 � i I i rn C .,� JJ ul v i� ,� •� � �n u� W � 3 N q �. �. � � Sx.i N N �0 d' CN +� a v r+ � � s, ro +� � •� o� cn d' � d' .t�.� •� •� dl N Ul �1-� .1� � O � 'a •�-�i •�-�i z � H w w 2-15 O -� � U N � � N � C .,� � v N .,� r-i ro c � .r., m c � ro � •a m c b o� -� a, �v JJ N � r0 •� Q N �-I b •�+ ro �ro rn U O� � U •� � cn Z7 � � � � N R7 � �� S.roa � U ap�, cr � O � U I.I I .-. ��v 1 � 0 0 N � � rn rn � x � w � � N v C] W W �-] W co a � � H � z H Z z a x W C� � a w � � v � i •� i +� i ro i �w i �, i a� i � i � i � I I I I I I v i � i •� i � i ro s� c c4 � �, o v x � � . s, � v a m v � � •� � � •� i +.� i b i c� i L I N I � I � I � i i i i i i rO I � i •� i �i � I I I O I z � o d� �n � o � � � o C1' �f 1 � � N M . .. . . .. . .y . .. . tfl N N c� �, �, � aG � �G � o ro o ro o � a� � a� •�+ w a � x x a� ro w ro w a a� w v a-� v a o a o E • rl M Op t-+ rn o rn o �—i N 2-16 0 �� v �� .,� � , ��� rd U O C � •r-I �-I Q, � N SC N �t-� N Ll, r-I rtl vl C •r., �+ � •� � � �n ro u v -� � �� O 3 N w .� , �, v a� � � W ro •� o � +� v ro� � � c ros.�a, v c � a, o r+ .c ro� � b�� 'a � U •rl f� s-i � 3 vw o � i +� 0 �n z a, s� rn �a�b O .� ii L � a1 � x�ro b � v N C Cl, U O k oa�� 3 rtf � sa 'i7 ro a� a� �, � �v. a O C +� � � •� 1.� 't7 U� � va,o ��� U N N X a� b x � a� a� � � a��� s�oa �s � o rnw N � �+ov � � � �� ro H � .� Year 1993 2008 TABLE 2.8 ESTIMATED ANNUAL TOTAL ACCIDENTS�1� ALTERNATIVES .

The increase in total number of accidents for Alternatives A and B over Alternative E is due to the greater length of the alternative corridor. 2.3.6 Review of Matrix Analysis The results of the matrix analysis will be used in conjunction with the cost-effectiveness analysis and public and agency comments to identify a recommended alignment subsequent to the public hearing. 2.4 ROADWAY COST ESTIMATE Estimated construction and right-of-way costs are presented in Table 2.9. Estimated costs (in 1988 dollars) range from a total high of $7,685,000 for construction of Alternative E to $5,855,000 for construction of Alternative A. 2.5 USER BENEFIT ANALYSIS A user benefit cost analysis was conducted to help determine the economic benefits of each alternative. The following paragraphs summarize a more detailed report document, User Benefit Analysis Technical Memorandum, which is appended by reference. The purpose of the user benefit costs analysis is to determine whether the expected economic benefits during the design period 2-18 r � , ' ' ' ' � � ' ' ' ' ' ' , , ' ' W E-i � � � N H Ei W V] a w � �C H H � O U IWI 0 �0 o � � � U� N O� U N � � � �� rn � c o b a a 0 0 '-+ o � v � � � � rn •� o � � U � b 04 �h C � � � � � r-i •r1 ,-1 � � r-I � 0 O �-I O c� � � U] M O� U M �C t� 1J N .� 1J r-�i C ro 00 00 00 N N 00 �Y' O M u'; 0 0 0 0 0 0 � � � � � � N 0 0 O O u1 O N O O dl O �t' N 0 0 0 � � � � � 0 0 0 � � � � � 0 O � u'1 � � �C1 � N C O • �-I tll � � U � �d! � b �+ � c � � ro [ o �, Ul r� Ll O •� U C Ul •� U] •� +-� C o c.0 �n � v.� ro a� .�+ v ocmc•�•� �,�r c •�a�a,b+�cn +-�� N 'J�,^ 1� '� C •�-I •ri tA •r� � ro m b•�•�,�r; � •�,+� O 3 v U U] t!l C•�-+ t3' C C � 'a rl O N� rtf � U •� O rd E c�•� �C�w���C EU .r.� O O £ � Z7 O U 6� � fZ � E� 2-19 � O .,a a-t U � i� � � � � U v rn ro � .,1 b S� � u� r-i S-i '--1 ro ro � � � O N A '� � w � 00 U � � r� H r-I N will exceed the estimated costs for the same period. Common discount rates are used to compare the alternatives according to guidelines published by the American Association of State Highway and Transportation Officials (AASHTO).2 Economic benefits consist of any reduction in road user expenses expected to occur as a result of drivers operating their vehicles on a safer, less congested, and more efficient highway. This includes personal time with its corresponding dollar value, vehicle operating expenses, and accident reductions. Project costs include engineering, right-of-way, construction and maintenance costs of the proposed alternative minus costs associated with maintaining the existing roadway. Table 2.10 presents the results of this analysis, which uses the Benefit/Cost Ratio as the measure of economic desirability. The Benefit/Cost Ratio is the ratio of the net present value of the total estimated annual benefits to the net present value of the estimated annual costs. An investment is considered to be financially desirable if the benefit/cost ratio is greater than 1.0. As shown in Table 2.10, all these alternatives are considered to be financially desirable due to the benefit/cost ratio being greater than 1.0. Alternative A shows the greatest benefit/cost ratio at all of the three discount rates, and thus would be considered as the alternative with the greatest desirability. 2-20 , , � ' ' , ' � , � � ' , ' ' ' ' ' ' TABLE 2.10 BENEFIT/COST ANALYSIS Alternative A B E Discount Rate 7 10 12 2.04 1.61 1.38 1.84 1.46 1.26 1.65 1.30 1.12 Note: All monetary benefits and costs in the user benefit analysis are in constant 1988 dollars. 2-21 2.6 PREFERRED ALTERNATE While the selection of an alternative will not be made until the impacts and comments from the Public Hearing and this draft environmental impact statement have been fully evaluated, Alternative A was identified as the preferred alternative. The Alternative A alignment will serve the future traffic needs of Boone and Watauga County. Alternative A will have minimal impact on the natural environ- ment. As shown in Table 2.3, Alternative A impacts no historical or archaeological sites', and has the fewest possible hazardous waste or petroleum storage sites within its proposed right-of- way. Alternative A also has a lower construction and right-of-way cost than Alternatives B and E. The roadway cost and right-of-way cost were discussed and summarized in Section 2.4 and Table 2.9. As shown in Table 2.10, Alternative A also has the greatest benefit/cost ratio. The advanced planning stages associated with Alternative A, lower cost, minimal environmental impacts, and service to the area all contributed to the selection of Alternative A as the preferred alternative. 2-22 CHAPTER 2 REFERENCES 1.

As a result, per capita and median family income levels in Watauga County are also lower than the state average, as shown in Table 3.2. Low income levels coupled with increasing land costs have resulted in county residents, especially young people, leaving the area in search of employment opportunities and higher wages.2 Poor transportation and accessibility have influenced and will continue to influence this trend. Employment by industry group in 1984 and 1985 for Watauga County is shown in Table 3.3, which highlights the downward trend of the manufacturing sector and the substantial increases in the tourism and service sectors. Additional evidence of this trend toward a non-manufacturing- based economy is provided in Table 3.4. Again, a decline in manufacturing employment to a non-manufacturing base is evident, reflecting the national trend toward a more service-oriented economy. The table shows that while 7.9 percent of the labor force was involved in manufacturing in 1980, this figure dropped to 4.9 percent in 1986. During the same period, non-agricultural wage and service employment remained constant at 50 percent, while non-manufacturing employment increased from 42 percent to 45.1 percent. Manufacturing provides 31.6 percent3 of statewide employment, as compared to Watauga County's 4.9 percent. 3-3 Year 1980 1981 1982 1983 1984 TABLE 3.2 INCOME DATA Per Capita Personal Income Watauga County $6,083 6,799 7,093 7,627 8,467 Median Household Income Year Watauga County 1969 $ 5,323 1979 11,039 Median Family Income Year Watauga County 1969 $ 6,149 1979 14,532 K�� N.C. $ 7,774 8,655 9,153 9,829 10,852 N.C. $ 6,976 14,481 N.C. $ 7,774 16,792 �i � � .� ' � � � � '. � � �' � � , � � ' TABLE 3.3 EMPLOYMENT DATA Annual Average Labor Force Estimates 1984 1985 Civilian Labor Force 16,150 16,890 Total Unemployment 900 740 Rate of Unemployment 5.6 4.4 Total Employment 15,250 16,150 Agricultural Employment 410 380 Non-agricultural Wage and Salary Employment Al1 Other Non-agricultural Employment (1) 13,280 1,560 14,190 1,580 Industry Employment by Place of Work 1984 1985 Manufacturing (2) 1,800 1,600 Construction 740 840 Transportation, Communication, and Public Utilities Trade Finance, Insurance, and Real Estate Service Government Other Non-manufacturing (3) 240 3,210 660 2,210 4,190 30 270 3,740 730 2,290 4,290 40 Percent Change 4.6 -17.8 5.9 -7.3 6.9 1.3 Percent Change -11.1 13.5 12.5 16.5 10.6 3.6 2.4 33.3 (1) Includes non-agricultural self-employed.workers, unpaid family workers, and domestic workers in private households.

In addition to full-time residents, the county, � due to its scenic beauty and recreational opportunities, had a part-time resident population of approximately 6,786 residents in � 1980 and an estimated population of 8,660 in 1985.4 From 1980 through 1985, the permanent population increased by 5.6 percent, while part-time residents increased by 27.6 percent. Watauga County's permanent resident growth rate is approximately 35 percent of the state growth rate, while its rate for part-time residents is almost twice that of the state. Statewide population growth rates are shown in Table 3.8. Further comparison of Watauga County population statistics with state figures reveals the following: - Population growth projections between Years 1990 and 2000 indicate a county growth rate of approximately 11.2 percent, � which is slightly higher than the statewide increase of 9.6 � percent (see Tables 3.7 and 3.9).

Between 1971 and 1981, the county adopted a building code and subdivision regulations; employed building inspectors, a subdivision coordinator, and a county manager; and � adopted a thoroughfare.plan (for Boone and its immediate vicinity only). The county has yet to adopt zoning in any portion of its area not controlled by a municipality. ' Boone published the Boone Land Development Plan in 1977, adopted a zoning ordinance in 1980, and has more recently adopted a , thoroughfare plan.

Some of this information is included in other planning documents.� 3.2.1 Existing Land Use Exhibit 3.1 depicts five categories of land use within the study area: commercial, residential, open field/agricultural, church, and cemetery. The residential category contains all housing types, including mobile homes. Following is a general description of the land use types traversed by each alternative: 1 Alternative A- This alternative, running in conjunction with and to the north of the existing US 421 corridor, involves strip and 1 scattered commercial, residential, cemetery, and church land uses. In addition, some agricultural land and woodland would be � impacted by this alternative. ' , r � ' � ' Alternative B- This alternative is similar to Alternative A except that it takes a southerly route from that of the existing US 421 corridor. Included land uses are scattered commercial and residential, open field/agricultural, and a small amount of woodland. 3-15 Alternative E- The road improvements within the existing right-of-way will have the greatest impact on existing man-made facilities. This alternative would require the relocation of many businesses and residences. Minimal open field/agricultural and woodland areas are located adjacent to the existing roadway. 3.2.2 Land Use Planning In 1988, the Watauga County Planning Implementation Policies were adopted, which provided a vehicle for citizen participation in the planning process. Citizens were polled regarding their concerns about the county's past, present, and future growth as related to its natural and man-made environment. Other planning tools available to Watauga County include the following: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. Ordinance to govern subdivisions and multi-unit structures. Sedimentation and erosion control ordinance. Flood damage prevention ordinance. North Carolina bui�lding code. North Carolina ridge law. Ordinance to govern the height of structures.

' 1 � i � � ' � �� � � � �J 3.3 CULTURAL RESOURCES Cultural features within the study area include existing churches, schools, cemeteries, and public and private open space, as shown in Exhibit 3.2. 3.3.1 Schools Watauga County Schools' Administrative Unit is composed of eight elementary schools and one consolidated high school. A center for exceptional children is located at Hardin Fork Elementary School, and Appalachian State University is located in the Town of Boone . 3.3.2 Recreational and Leisure Activities Both the Town of Boone and Watauga County offer a variety of recreational and leisure activities; however, none of these facilities is located within the immediate study area. 3-17 3.3.3 Historical and Archaeological Resources A records search revealed only one archaeological site, and that was destroyed by residential construction. The only potential historical site was deemed ineligible for the National Register of Historic Places due to lack of integrity.8 The archaeological investigation is summarized in a report entitled An Archaeological Reconnaissance Survey of Proposed US 421 Improvement by Archaeological Research Consultants, and the historical/architectural investigation is summarized in a report entitled Historic Structure Survey and Evaluation Report for US 421 Environmental Impact Statement by Ms. Margaret Long Stephenson, both appended by reference. 3.4 UTILITIES 3.4.1 Electrical Power The Town of Boone is primarily served by New River Light and Power Company, which is a distribution utility. The area is also served by Blue Ridge Electric Membership Corporation, a transmission and distribution utility, which is the primary supplier of electric energy in northwest North Carolina. Electrical power requirements up to 110 kilovolts (kV) are available. The Town of Boone is looped by a 46-kV transmission system. Exhibit 3.3 shows existing power transmission lines. K��:, ' ' New River Light and Power Company is located on Winkler's Creek Road in Boone and is owned by the Appalachian State University � Foundation. It serves 6,000 consumers, including the university ' campus. Its primary distribution system is 7,200 volts. � Blue Ridge Electric Membership Corporation is a cooperative owned by its consumers. The Watauga District Office is located on US � 421 South, and the corporate headquarters is located in Lenoir, North Carolina. The Watauga District provides service to 15,500 jmeters, including the New River system. Its distribution system � is supplied at 7,200 volts. Two 100-kV transmission lines are the primary sources for the area, which has a 46-kV transmission � network. � 3.4.2 Fuel Oil Fuel oil is available from several local distributors. Bulk � supplies are available at competitive prices, primarily from the ' Charlotte, North Carolina area. , 3.4.3 Natural Gas Although natural gas is not available in Boone or Watauga County, ' there are three local distributors of propane gas. Suburban � Propane on Meadowview Drive is the principal supplier within the town of Boone. � ' 3-19 lJ ' 3.4.4 Telephone Service Telephone service is provided by Southern Bell in Boone and Skyline Telephone Membership Corporation throughout Watauga County. Al1 primary long distance carriers serve the area. 3.4.5 Water The Town of Boone's Municipal Department provides water to residential and commercial users within the town limits. Users outside of Boone must rely on drilled wells. Exhibit 3.4 shows the water lines serving the study area. 3.4.6 Sewer The Municipal Department also provides residential and commercial users within Boone with sewage disposal service. Some users outside of the town limits are also connected to the centralized sewerage system. Those that are not must rely on underground septic systems. Exhibit 3.4 also shows sewer lines. 3.4.7 Railroads There is no rail service directly into Boone; however, piggyback service is available at Hickory/Conover, approximately 50 miles away. Frequency of switching service is daily. 3-20 c 3.5 MINERAL RESOURCES There are presently no operations for mineral extraction in the study area. Existing urbanization and industrial land use are prohibitive to rock quarrying. There are no significant commercial sand, gravel, or clay deposits within the study area, and the potential for future development of mineral resources is low. 3.6 PHYSICAL ENVIRONMENT The North Carolina Environment Policy Act established that all major actions to be funded by the North Carolina State Government must be assessed to determine their impact on the environment. This includes noise levels, air quality, and water quality within the study area and surrounding regions that may be affected during and after construction. 3.6.1 Noise ' The principal source o�f noise within the study area is vehicles from existing US 421. Other sources include construction, farming, and yard work. Section 4.5.1 of this report presents � the anticipated impacts of the construction alternatives on ' existing noise levels. �J � � ' 3-21 3.6.2 Air Quality The U.S. Environmental Protection Agency (EPA) and the North Carolina Department of Natural Resources and Community Development (DNRCD) have established criteria to define air quality. EPA has established two standards for air quality: primary and secondary. Primary standards are those levels required to protect the public health with an adequate margin of safety. Secondary standards are those levels required to protect the public health from any known or anticipated adverse effect of an air pollutant. These criteria are designated as the Ambient Air Quality Standards (AAQS) and are established for seven air pollutants: carbon monoxide (CO), lead (Pb), nitrogen dioxide (NO2), sulfur dioxide (S02), particulate matter (TSP), particulate matter at or less than 10 microns (PM10), and ozone (03). These standards and those of the DNRCD are shown in Table 3.11. Neither EPA nor the DNRCD currently monitors levels of CO, 03, NO2, TSP, or PM10 in Watauga County or the Town of Boone. According to the Clean Air Act Amendments of 1977, all areas within the state are designated as either attainment, non-attainment, or unclassifiable with respect to the AAQS. Areas that meet the AAQS are designated as attainment. Areas where the AAQS are not met are designated as non-attainment. In non-attainment areas, a State Implementation Plan (SIP) is developed to bring the area into compliance with the AAQS. 3-22 Pollutant TSP S02 NO2 CO 03 �� , PM10 TABLE 3.11 AMBIENT AIR QUALITY STANDARDS Time of Avg.

Based on past monitoring, however, the area should be well within all air quality standards. 3.6.3 Water Quality Surface Water - The principal water course in the study area is the South Fork New River. Surface runoff is also collected by Hardin Creek and an unnamed stream that parallels US 421 approaching the river; both are tributaries to the river. The South Fork New River is classified by the State of North Carolina as a Class C waterway. Class C waters are fresh waters suitable for fish and wildlife propagation, agricultural uses, secondary recreation (boating and wading), and uses requiring waters of lower quality. The river is used as a secondary source of supply by Boone's municipal water company, which routinely tests the headwaters for fecal coliform bacteria. Boone also tests the Winkler Creek tributary for chemical properties, temperature, and turbidity. Test results for 1988 are shown in Table 3.12. The Boone municipal wastewater treatment plant discharges effluent into the South Fork New River 0.5 mile upstream of the US 421 river crossing. Biochemical oxygen demand (BOD) in the river is recorded upstream and downstream from the.plant. Test results for July and August 1988 are shown in Table 3.12. 3-24 � � , ' ' ' � � , , ' � � ' � � ' ' ' TABLE 3.12 QUALITY OF SOUTH FORK NEW RIVER HEADWATERS JANUARY THROUGH DECEMBER 1988 1988 (Units in Parts Per Million, Unless Otherwise Noted) Months O1 02 03 04 05 06 07 08 09 10 11 12 Parameter Temperature (°C) 5 5 7 10 13 16 19 20 16 10 8 5 Turbidity (JTU): Range 0.4- 0.5- 0.5- 0.7- 0.7- 1.3- 1.6- 1.6- 1.2- 0.6- 0.6- 0.4- 17 4.3 3.5 25 62 19 46 17 40 4.0 80 3.2 Median 1.4 0.9 1.0 2.5 4.2 3.1 6.2 3.8 4.5 1.1 3.8 0.8 pH 6.9 6.8 6.9 6.9 7.0 6.9 6.9 6.8 6.9 7.0 7.0 7.0 Iron 0.21 0.07 0.03 0.12 0.12 0.05 0.24 0.16 0.12 0.08 0.05 0.07 Manganese 0.01 0.04 0.01 0.01 0.02 0.03 0.03 0.02 0.03 0.03 0.02 0.02 Fluoride 0.01 0.02 0.01 0.01 0.01 0.02 0.02 0.04 0.03 0.02 0.04 0.02 Carbon Dioxide 2 2 2 2 2 2 2 2 2 2 2 1.4 Fecal Coliform per 100 ml 22 22 10 62 74 88 166 158 102 70 54 20 BOD: Above Wastewater Treatment - Plant -- -- -- -- -- -- 65 -- -- -- -- Below Wastewater Treatment Plant -- -- -- -- -- -- 40 -- -- -- -- 3-25 On-site observations for pollution were conducted of streamflows and their physical parameters within the study area. Readily observable indications of pollution include odor, bubbles, oil slicks, unusual color, siltation, and bed loading. Signs of pollution were observed only in Hardin Creek at US 421; although stream flow was clear, surface bubbles and an organic odor were detected. Areas drained by the creek include a shopping center, commercial properties along US 421, and the Boone Lumber Company. Both the South Fork New River and the stream that enters it just south of US 421 were observed to be clear, with little siltation of the stream beds and no indication of pollution. As shown in Table 3.12, levels of turbidity increase significantly after a rainfall event. Turbidity refers to the cloudiness of the water and, in the study area, is largely dependent on runoff conditions as material is added to the water from vegetation, surface litter, soils, and rocks with which the surface runoff of precipitation comes in contact. It is measured in Jackson turbidity units (JTU), which are equivalent to the interference to light transmission caused by 1 milligram per liter (mg/1) of a standard suspension. Turbidity restricts the penetration of sunlight through water, thus decreasing plant photosynthesis, and can also impair respiration in fish. Ground Water - Ground water is found below the water table where all openings in the soil or rock are completely filled with water. The water table in the study area is usually found at 3-26 depths less than 40 feet in the saprolite overlying the fractured bedrock.9 In the lowlands, ground water may be encountered at depths between 5 and 20 feet. The base flow in streams and creeks in the study area is from ground water discharge, which occurs where elevations of the water table lie above the soil surface.l� In the bedrock below the water table, water fills the network of interconnected fractures. An idealized geophysical cross section showing ground water storage is depicted in Exhibit 3.5. The fractured character of the bedrock is conducive to the existence of a water table or unconfined aquifer. Ground water contained in water table aquifers is recharged (replenished) locally mainly from precipitation infiltrating the overlying soils.11 Ground water recharge in this area is shunted laterally through fractures in the rocks to points of discharge less than 1 mile (commonly less than 0.5 mile) from their point of arrival at the water table.12 Most domestic water supplies outside Boone's town limits come from drilled wells, which draw water from fractures in the bedrock. These fractures diminish in size and number with depth so that drilling wells deeper than 300 feet will not substantially increase well yields.13 An estimated fifty to sixty wells and one spring lie within the study area. The wells range from 100 to 200 feet in depth and intersect the water table at an average depth of 40 feet. 3-27 3.6.4 Floodways and Flood Plains The floodway width and boundaries are as indicated by the Federal Emergency Management Agency (FEMA) and by Boone's municipal planning department's Flood Boundary and Floodway Map. One ingression of right-of-way within a 100-year flood boundary was identified and is shown on Exhibit 3.6. The affected area is adjacent to the existing crossing of Hardin Creek by US 421 and is common to all alternative alignments. 3.6.5 Hydrology and Drainage The study area is located within the watershed of the South Fork New River. The drainage area of the watershed above the bridge on US 421 is 34.8 square miles.14 Drainage patterns are closely related to topographic relief. Stream channels are well defined and carry significant flows following normal precipitation. During dry periods, they may carry a base flow of discharging ground water or have dry bottoms. The western section of�the study area is drained by Hardin Creek to the South Fork New River. Present runoff conditions frequently overload Hardin Creek, causing the creek to overflow its stream bed and flood adjacent residences. The northeastern section drains to the river via an unnamed stream. The remainder of the study area drains directly to the South Fork New River, which borders the area to the east and south. 3-28 Runoff conditions durinq base flow.

' ' ' � ' 3.6.6 Topography, Geology, and Soils Topography - Watauga County lies within the Blue Ridge physiographic province in the broadened inter-valley of the South Fork New River drainage basin and is bordered by the river on the east and south.15 The project area is generally characterized by moderately rolling uplands with localized steep slopes. Small areas of nearly flat terrain are present in the lower elevations at the east and west boundaries. Elevation averages approximately 3,200 feet above sea level. The highest peak contiguous to the study area lies to the north and rises 3,640 feet above sea level. The lowest point, located at the westernmost portion of the study area, is at Elevaton 3150. Geology - Land within the vicinity of the study area is underlain by a layer of disintegrated (weathered) rock referred to as "sap- rolite" or "residuum" and bedrock that is a lower unit of the Grandfather Mountain Window geologic group.16 Well logs indicate that saprolite depth varies from a few inches to approximately 50 feet. Positioned 2 to 3 miles north of the inactive Grandfather Mountain fault line, the area's bedrock is broken in an intricate network of fractures, as represented on Exhibit 3.5. The dominant rock type is Cranberry granite gniess, which is intermixed and interlaid with hornblende gneiss, mica gneiss, and mica schist.l� 3-29 The Blue Ridge province is underlain by a complex assemblage of metamorphic and igneous rock types. As a result of the variable nature of lithologies within the province, compositions, textures, and structural features of mineral assemblages are heterogeneous and anisotropic. Boundary transitions between rock types are generally not well defined.l$ A geologic map of the region is shown on Exhibit 3.7. There are no known major active faults within the province, and the seismic activity of the study area is low. Soils - Soils in the study corridors for US Route 421 between Boone and the South Fork New River have been mapped into six soil series: Halewood, Porters, Perkinsville, Tusquitee, Hatboro, and Chewacla.l9 The Halewood series is the most prevalent and comprises approxi- mately 40 percent of the study area. These soils are found on the tops and sides of mountains, ridges, and hills at elevations up to 4000 feet. They are residuum of'granite and low micaceous� acid schist and gneiss. Halewood soils are classified as moderately drained, moderately permeable, strongly acidic, and with medium to high surface runoff. Erosion potential is moderate if unprotected. Porters series soils represent approximately 60 percent of the study area north of US 421 and 10 percent of that area south of US 421. Porters soils are residuum of the same weathered, low 3-30 micaceous igneous and metamorphic rocks as the Halewood series, and to some extent hornblende gneiss, hornblende schist, diorite, and metadiabase. Characteristics of Porters and Halewood soils are very similar, mainly differing in the more friable medium-texture of the Porters' subsoil. Due to this very friable subsoil, which has a high capacity for absorbing water, Porters soils are less erodible. Erodibility is slight to moderate for unprotected slopes with less than 30 percent grade. An estimated 45 percent of the area south of US 421 consists of soils from the Perkinsville series. These soils are derived by disintegration of the same bedrock as the Halewood series and differ mainly in color, being more yellow. The surface soil contains some rock fragments (mostly quartz), and the subsoil contains a few partly decayed rock fragments up to 2 inches in diameter. Perkinsville soils are moderately erodible when not protected by vegetation or other means of erosion control. Tusquitee soils are present in two small areas traversed by all corridors� These colluvial soils occur adjacent to areas of Porters and Halewood soils on the foot slopes of mountains and hills, from which they have washed. They are moderately well drained and have medium to� strong natural acidity. Surface runoff is medium to low, with a slight hazard of erosion on steeper, unprotected slopes. 3-31 Hatboro loam is found in the stream bottoms of Hardin Creek and its feeder branches. Formed from young alluvial material, its texture ranges from loam through loamy fine sand to gravel, and its organic matter content is medium to low. Surface runoff is low, with slow internal drainage. A stream bed roughly paralleling the existing US 421 highway west from the South Fork New River consists of Chewacla loam. Occurring on nearly level alluvial flood plains, this soil consists of material originating chiefly from gneiss, schist, and granite. Surface runoff and internal drainage are slow. Substratum may consist of sand, gravel, or cobbles. Above the water table, permeability is moderate to moderately rapid. 3.6.7 Hazardous Waste Disruption of hazardous waste sites during roadway construction could have a detrimental effect on surface water, ground water, soils, vegetation, wildlife, human health, and human welfare. Hazardous waste is generally defined as any waste material that has or, when combined with other materials, will have a dele- terious effect on people or the environment. Characterized as either reactive, toxic, infectious, flammable, explosive, corrosive, or radioactive, hazardous wastes may be solids, sludges, liquids, or gases. Potential hazardous waste sites include landfills, dumps, storage tanks. pits, lagoons, salvage areas, and 3-32 , �I ' The following sources were used to identify potential hazardous ' waste sites within the study area: - Field inspection and evaluation of existing land use. ' - Aerial photographs and topographic maps. ' - Local representatives of agencies responsible for pollution control, hazardous material regulation, and public safety. , - Records of state and, local agencies regarding hazardous material use and disposal. ' - Government publications of known hazardous waste sites. , North Carolina's hazardous waste management program is primarily directed by the state's Department of Human Resources (DHR), ' Division of Health Services - Solid and Hazardous Waste Manage- ' ment Branch. Other agencies consulted in the identification process were the Town of Boone's public utilities and fire � departments and a local waste management company. ' One known and three potential hazardous waste sites are located within the study area. The name, address, and a brief ' description of each are given in Table 3.13; Exhibit 3.8 shows the locations of the sites. All are sites of storage tanks for �petroleum products. Underground and aboveground tanks used for ' petroleum product storage are not generally considered signifi- cant hazardous waste sites; however, hydrocarbon contamination of ' soil and ground water can result from leakage or spills at these locations.

The team's inventory of natural ' systems is included in the report US Route 421 Flora and Fauna ' Inventory and General Overview appended by reference.20 The following is a report summarization. ' ' 3.7.1 Flora Survey ' The vegetation within the proposed project area is a mixture of three general types: urban plantings, pasture land and open , fields, and small secondary growth forests. The secondary growth forests are composed of agricultural coniferous plantings, pine ' forests of various ages, and mixed hardwood stands of varying ' composition and age. There are no tracts of virgin woodland or wetland in the project area. Floral species that are endangered, ' threatened, or that deserve special attention were not encountered. ' ' 3-35 3.7.2 Fauna Survey Much of the project area has been disturbed by man's activities; however, the biological requirements necessary to sustain wildlife populations (food, shelter, and water) are available. The Eastern chipmunk (Tamias striatus) and the cottontail rabbit (Sylvilagus floridenus) were observed in the area. Other mammalian species reported to be in the area, including big game species, were not observed. Avian species observed were the common crow (Corvus brachyrhynchos), mockingbird (Mimus polyglottis), field sparrow (Spizella pusilla), cardinal (Richmondea cardinalis), robin (Turdus migratorius), and turtle dove (Zanaidura macroura). Other non-game birds were heard, but were not observed. None of the reptiles or amphibians believed to exist in the Pisgah National Forest, or its immediate environs, was observed in the project area. A field study of fish in the South Fork New River was n,ot conducted for this study. However, in prior studies conducted on the New River and its tributaries, 3 species of trout, 16 species of minnow, 2 species of suckers, 5 species of sunfish, 4 species of darters, and 2 species of sculpin were identified. None of these species are considered endangered, threatened, or of spe.cial concern; however, all efforts should be made to maintain undisturbed the state-supported fishery of Ambloplites rupestris and Micropterus dolomieui that exists in the South Fork New River. 3-36 3.7.3 Wetlands Wetlands are important natural resources that benefit the total physical environment. Potential functions of wetlands include habitat for wildlife, recharge areas for ground water, inter- ception and mineralization of organic runoff, hydraulic baffling and mediation of downstream currents, and sedimentation of turbidity in runoff waters. The definition of wetlands is given in Executive Order 11991, Section 7(c): The term "wetlands" means those areas that are inundated by surface or ground water with a frequency sufficient to support and under normal circumstances does or would support a prevalence of vegetative or aquatic life that requires saturated or seasonally saturated soil conditions for growth and reproduction. Wetlands generally include swamps, marshes, bogs, and similar areas such as sloughs, potholes, wet meadows, river overflows, mud flats, and natural ponds. The DNRCD has classified wetlands as areas having hydric or � predominantly hydric soils. Hatboro loam and Kinkora loam are 1 classified as hydric �soils. Hatboro loam is conjunctive to Hardin Creek at the western edge of the project corridor; , however, this area is in commercial use. Alternative B crosses an area of Kinkora loam less than 1 acre in size, which is � presently in residential use. Other potential wetlands areas are � adjacent to the South Fork New River; however, these areas have been converted to row cropping and pasture land. � 1 �J 3-37 3.7.4 Prime and Important Farmlands Prime and important farmlands are identified by the following soil types provided by the Watauga County Soil and Water Conservation Service of the USDA: Evard .(formerly Halewood), Porters, Ineyville (formerly Perkinsville), Tusquitee, and Kinkora.21 Exhibit 3.9 shows portions of the study area representative of these soils. Most of the study area is classified by soil type as prime or important farmland; however, existing urban, commercial, and industrial development of the area precludes agricultural use. Current agricultural production is limited to Christmas tree farming on the hills south of US 421. 3.7.5 Wild and Scenic Rivers Wild river areas are defined as "rivers or sections of rivers that are free of impoundments, and generally inaccessible except by trail, with watersheds or shorelines essentially primitive and unpolluted." Scenic river areas are defined as "rivers or sections of rivers that are free of impoundments, with shorelines or watersheds still largely primitive and shorelines largely undeveloped but accessible in places by roads." According to officials at the DNRCD, there are no state or federally designated wild and scenic rivers in Watauga County. 3-38 � � � � � � � � m � � � � � � � � � i �I 1 � CHAPTER 3 REFERENCES 1.

C�' C 1 , ' � 4.1.1 Economics The improvement of US 421 will have the following economic effects: - Increase construction-related employment. - Eliminate some property tax role lands. - Alter property values. - Reduce travel costs due to a safer and less congested roadway. ' All of the alternatives will have a positive employment impact. Construction costs for the improvement construction of US 421 ' from NC 194 to just west of the South Fork New River ranges from $2,603,000 to $4,553,000. Using a common multiplier of three ' times the initial construction cost, the improvement of US 421 ' will contribute aetween $7.8 million and $13.6 million in additional income over the life of the pro�ect.

Residential properties adjacent to the improved road that experience increased noise levels or negative visual impacts will probably decrease in value. Commercial and industrial properties adjacent to the new roadway should rise in value, however, due to their increased accessibility. 4.1.2 Relocations Relocations and displacements will be necessary under all of the alternatives; however, the estimated number of displacees is different for each, as shown in Table 4.2. Alternative A should result in the fewest family and business displacements, while the other two alternatives will require about the same number of displacees of both families and businesses. Alternative E will have an estimated gravesite displacement of apporoximately 100. A detailed Relocation Report is included in Appendix B. The NCDOT has determined that adequate residential and business property is available to relocate those displaced and offers several programs designed to minimize the inconvenience of relocation. Under the Relocation Assistance Program, experienced NCDOT staff would provide displacees with information on availability and cost of homes, apartments, and businesses for sale, as well as financing and other housing programs. The Relocation Moving Payments Program, in general, provides for payment of actual moving expenses incurred during relocation. 4-3 TABLE 4. 2 RELOCATION REPORT ESTIMATED NUMBER OF DISPLACEES ALTERNATIVE TYPE OF DISPLACEE Families Businesses Total A 10 3 13 B 23 6 29 E 24 4 28 . . ' LJ .' �J ' ' ' ' .' CI' ' , ' ' l_� , , ' ' Where displacement will force an owner or tenant to purchase or rent property of higher cost or to lose a favorable financing arrangement, the Relocation Replacement Housing Payments or Rent Supplement Program will compensate owners who are eligible and qualify up to $4,000. When families cannot be relocated within their financial means, and/or cost of replacement housing falls outside these limits, the law provides for Last Resort Housing. This program allows broad latitudes in methods of implementation by the state so that safe, decent, and sanitary replacement housing can be provided. It is not believed that this program will be necessary. The gravesite relocations will be handled by officials with the NCDOT staff. A search will be conducted to locate family members of those buried in each gravesite and a suitable relocation will be found. 4.2 CULTURAL RESOURCES 4.2.1 Schools The only school close to any of the corridors, Hardin Fork Elementary School, would not be impacted by any of the alternatives. 4-5 4.2.2 Section 4(f) of the Department of Transportation Act Section 4(f) is not required of an exclusively North Carolina State funded project such as this. Regardless, none of the alternatives will require the use of any park, wildlife refuge, or recreational land as defined in Section 4(f) of the 1966 U.S. Department of Transportation Act, as amended. 4.3 UTILITIES 4.3.1 Electric Power All alternatives cross the transmission lines that run north- south through the project area, and minimal impacts are expected. Utility relocation is included in the costs estimated in Section 2.4. 4.3.2 Water and Sewer All alternatives cross areas now served by both water and sewer lines. Utility relocation is included in the costs estimated in Section 2.4. 4.4 MINERAL RESOURCES No existing mines or sites favorable for mining of any mineral resource are known. If, however, an underground mine were encountered during construction, a detailed survey and investigation should be conducted to determine proper abandonment techniques. 4-6 ' ' 4.5 PHYSICAL ENVIRONMENT ' 4.5.1 Noise , A preliminary noise analysis was conducted to determine existing and anticipated noise levels and possible mitigation measures for ' sites exceeding the noise abat�ment criteria. This analysis was conducted using the methodology outlined in Title 23 of the ' Code of Federal Regulations.l ' Noise Abatement Criteria - Noise abatement criteria guidelines ' are established by the FHWA and are shown in Table 4.3. These levels represent the upper limits of acceptable noise conditions ' and are applicable to places of regular human activity, not to an entire tract of land upon which a particular activity is based. ' Exceptions include areas where serenity and quiet are considered ' essential even though the areas may not be subject to frequent human use. An area is said to be adversely affected if a ' predicted noise level is within 2 adjusted decibels (dBA) of the criteria established in Table 4.3, or if the predicted noise ' impact is equal to or exceeds the existing noise level by 15 dBA. ' Existing Noise Levels - Noise measurements were taken at 12 sites within the existing corridor using standard data collection ' techniques outlined by the FHWA.2 The sites chosen represent a ' mixture of rural, residential, and commercial areas. Exhibit 4.1 shows these noise monitoring locations. , � ' 4-7 � H a w H H M U d' E1 z ww �w H � ao � W � H 0 z � 0 � N � ro V ? +� .,i � .,-i � U � w 0 c 0 .r., � C!, .,1 L U m a� A L � v a � +� � •� o � •ri � 1-1 J-J U b � U � a, ro v� � c � s, �, a, +� v� -� m �vs� �v � �.� ro o� � o •� 3 na � v o � � � � � � L r� � � � U o � � v ,� ,� �n Sa � 4a � U V � � � •.i C J-� � • � Ul v v� ro� �, o • c .ro o o � � `�-' � • ' .� [ a �•�a�iu�i '�� � [i, �,�mo 0 � A cn C)., � � •� •'"� �r � N s.i 0 U] � '�'� •r-t O� i+ •� N a� � �;' •� �� a..i � • rd '� rd O � •� � �� �,� � �� tJ' s-i ''i � � rt1 p +� � � vl S.r .Q � •'i .4-� UI rl O � � ���� roa, a�n c .'., ro •� a� � r, b a �, o � , �s � ay u� ro e �, � �., � r� � .,�� .

This measurement of Leq is based on energy averaged, A-weighted decibels of dBA. Measured noise levels ranged from 46.5 to 73 Leq, as shown in Table 4.4. The three highest Leq sites--30, 38, and 52--are located along existing US 421. The quietest area measured was Site 59, which is located far from any major roadway. Generalized Future Traffic Noise Levels - The impact of each proposed alternative, as well as the No-Build Alternative, was determined by comparing probable future traffic noise levels with existing noise levels using approprxate FHWA noise abatement criteria for receptors along each project. The computer program STAMINA/OPTIMA 2.0 was used to predict future noise levels.3 This information is shown in Table 4.5.

As shown in Table 4.5, each receptor is identified by land use activity and compared to the noise abatement criteria established for the different land use activities. Those receptors that exceed their respective noise abatement criteria are identified in Table 4.5. By Design Year 2008 under a no-build scenario, approximately 29 receptors would experience a noise level in excess of the noise abatement criteria, as shown in Table 4.6. The majority of receptors that exceed the noise abatement criteria for all of the construction alternatives would a.lso exceed those criteria under the No-Build Alternative. In some instances, there would even be a reduction in the predicted noise levels under the construction alternatives. The following preliminary evaluation of various noise abatement measures was conducted with respect to the proposed alignment alternatives using federal guidelines on noise abatement: * Noise Barriers - The use of noise barriers appears to be impractical at all locations for the following reasons: - 90-foot right-of-way - Partial access control - Commercial sites lining US 421 - Impact on site distance, drainage, access, and future development. However, once the final alignment is chosen, the use of noise barriers will be reexamined. 4-12 � W H � £ H N � � .

Roadway alignment development is planned to prevent or minimize the necessity of these actions. * Land Use Controls - One of the most effective noise abate- ment measures is proper land use controls. Once an alignment is selected, local jurisdictions should limit the growth of noise-sensitive land uses adjacent to the proposed roadway using setback requirements, building codes, and zoning. 4.5.2 Air Quality An air quality assessment was made to determine the air emissions associated with existing US 421 and/or improvements. Motor vehicles are known to emit CO, NO, hydrocarbons (HC), TSP, 502, and Pb (listed in order of decreasing emission rate). Different assessment procedures are required for each of these pollutants. Carbon Monoxide - Two concentration components make up the CO levels: background and local. The background component is due to CO emissions from cars on other streets or other sources. The local component is due to CO emissions from automobiles on the study highway. In the absence of site-specific or recent actual measurement of background CO, default CO concentrations were used as directed by officials at the DNRCD. These background CO values were added to the calculated local one-hour and eight-hour 4-14 ' � e � � � ' ' � , � � �' � ' ,� � ' 1 , CO results. The one-hour and eight-hour background CO conceritrations used are 2.0 parts per million (ppm) and 1.5 ppm, respectively. An indirect source analysis was used to calculate local CO concentrations. This analysis was conducted first on the worst- case scenario, the location that has the highest traffic volumes for all of the alternatives. The premise of this approach is that local CO concentrations elsewhere along the project corridor will be lower when compared to this potential worst-case scenario. The indirect source analysis was performed in accordance with guidelines issued by the DNRCD.4 The analysis was conducted at the locations of highest estimated average daily traffic under both no-build and construction scenarios for Design Year 2008. Receptors of CO concentrations were taken at the rights-of-way boundaries. Two receptors at each side of the right-of-way, which is 45 feet from the center of the road, were used as measurements for the alternative construction corridors. The No-Build Alt2rnative's two receptors were located at the existing rights-of-way, which are 50 feet on each side of the centerline of the existing road. The dispersion of CO for both the no-build and alternative construction corridors was simulated using the FHWA CALINE4 line source dispersion model.5 Input parameters provided by officials at the DNRCD are summarized in Table 4.7. 4-15 TABLE 4.7 DATA PARAMETERS FOR USE IN THE INDIRECT SOURCE DISPERSION ANALYSIS MODELING Model Parameters MOBILE3 Region Tapering rate Inspection/Maintenance Ambient temperatures Vehicle mix Vehicle speeds CALINE4 Stability class Surface roughness Wind speed Wind direction Mixing height Receptor height Receptor locations Persistence factors Link traffic volumes Background concentration One hour Eight hour Settling and Deposition Velocity 4-16 Value Low altitude No input None 26° F Default 50 mph F 125 cm 1 meter/second 0°-350° @ 10° intervals 400 meters 1.5 meters Rights-of-way � 0.75 Peak hours 2.0 ppm 1.5 ppm � Motor vehicle emission rates were computed using the MOBILE3 emissions model developed by the U.S. EPA.6 Input parameters received from officials at the DNRCD are also shown in Table 4.7. The analysis was conducted under simulated worst-case meteorological condition, including low wind speed, stable non-mixing atmosphere, and low ambient temperature. The computer simulation of future traffic and meteorological conditions was conducted for peak one-hour conditions. To account for the variation in traffic and meteorological conditions over time, a persistence factor was used to convert the worst-case, one-hour resul�ts to the corresponding worst-case, eight-hour results. A one-hour to eight-hour persistence factor of 0.75 was used for this purpose as dictated by the DNRCD. Table 4.8 presents the one-hour CO concentration results of the worst-case scenario for both the no-build and construction alternative alignment corridors. As shown in Table 4.8, neither the no-build nor the alternative alignment corridors' highest one-hour CO concentration exceeds the AAQS for CO (35 ppm), as shown on Table 3.11. Thus, based on these data, neither the one-hour nor eight-hour AAQS is likely to be exceeded at any point along any of the corridors throughout the design year. Hydrocarbons and Nitrogen Oxides - Automobiles are generally regarded as significant sources of HC and N0. HC and NO emitted from cars are carried into the atmosphere where they react with sunlight to form 03 and NO2. It is the resulting 03 and NO2 that are of concern. 4-17 TABLE 4.8 ESTIMATED WORST CASE ONE-HOUR AND EIGHT-HOUR CARBON MONOXIDE CONCENT?ATIONS No-Build Alternative One-Hour Eight-Hour Receptor (ppm) (ppm) 1 5.2 3.2 2 5.4 3.4 AAQS for CO: One-Hour 35 ppm Eight-Hour 9 ppm . � Alternative Alignment Corridor (Build) One-Hour Eight-Hour �APm) �PPm) 3.6 2.6 3.9 2.8 Area-wide automotive emissions of HC and NO are expected to decrease in the future due to the continued installation and maintenance of pollution control devices on new cars. No appreciable changes in area HC and NO automotive emissions are expected with either the no-build or alternative alignment corridors. Watauga County and the Town of Boone are unclassified for 03 and NO2, but are considered to have a relatively low concentration of both. Particulate �9atter and Sulfur Dioxide - Automobiles are not generally regarded as significant sources of TSP and S02. Nationwide, highway sources account for less than seven percent of TSP emissions and less than two percent of S02 emissions. TSP and S02 emissions are predominantly the result of non-highway sources (e.g., industrial, commercial, and agricultural). Air quality standards for TSP and S02 are unclassified for Watauga �County and the Town of Boone. Because emissions of TSP and S02 from cars are very low, there is no reason to suspect that traffic on the No-Build or alternative alignment corridors will cause air quality standards for TSP and S02 to be exceeded. ' Lead - Automobiles emit lead as a result of burning gasoline containing tetraethyl lead, which is added by refineries to ' increase the octane rating of the fuel. New cars with catalytic Iconverters burn unleaded gasoline, eliminating lead emissions. Also, the U.S. EPA has required the reduction in the lead content , � 4-19 � of leaded gasolines. The overall average lead content of gasoline in 1974 was 2 grams per gallon and is expected to be 0.05 gram per gallon by 1990. Air quality standards for lead are unclassified in Watauga County and the Town of Boone. In the future, lead emissions are expected to decrease as more cars use unleaded fuels and as the lead content of leaded gasoline is reduced. Therefore, it is not expected that traffic on the no-build or alternative alignment corridors will cause the AAQS for lead to be exceeded. 4.5.3 Water Quality Surface Water - Impacts to surface water quality associated with this project would result from suspended solids and dissolved minerals transported by storm runoff from the completed project and possible erosion and sedimentation during construction (see Section 4.9.1). Suspended solids cause turbidity in surface waters and sedimentation in stream beds. The risk of potential impact varies directly with the following: - Depth of right-of-way cuts. - Surface area of cut and fill slopes. - Steepness of slopes. - Erodibility of soil type. - Proximity of affected areas to surface waters. - Increase in paved surface.area. 4-20 � � , � ' � � � ' ' ' � ' a � � , ' 1 Alternative E would require the least increase in impervious (paved) surface area. Alternative A would require a lesser increase than Alternative B. Although none of the soil types in the study area is highly erodible, erodibility of soil types encountered in the eastern half of the study area differs with right-of-way alignment. The Porters series soils, associated mainly with Alternatives A and E, are less erodible than the Perkinsville series, the soil type mainly associated with Alternative B. Saprolite, which underlies l,and in the study area, is less leached at increased depths; therefore, saprolite e.xposed in cut sections will contain a higher percentage of soluble materials than surface soils. Runoff passing through freshly exposed saprolite will have increased dissolved solids concentrations. This impact will not be significant as the rock group underlying the study area is not highly soluble and yields a soft, slightly acidic ground water with low concentrations of dissolved constituents.� Stringent erosion control measures are mandated by the FHWA and the North Carolina Sedimentation Pollution Control Act of 1973. The law requires that an erosion and sedimentation control plan be approved before land-disturbing activities begin. The plan must include temporary and permanent control measures to prevent accelerated erosion and off-site sedimentation. These control measures must ',� designed to provide protection from a rainfall 4-21 event the magnitude of the 10-year storm (5Z inches of rain in a 24-hour period). Specific requirements of the law limit the angle of cut and fill slopes, restrict runoff velocities, and specify that permanent ground cover sufficient to prevent erosion be provided. Where design constraints allow, grass medians with swales may be used as drainage areas. These would provide detention of runoff and promote infiltration. If necessary, detention ponds, excavated sediment traps, or vegetative filters could be used to prevent degradation of the present water quality. With proper implementation of these pollution control measures, storm runoff from the completed project is not anticipated to have a significant impact on the quality of surface water in the area. Ground Water - The probability that any given alignment will affect the existing ground water ecosystem is relative to the depth of its cut sections. Ground water tables in the vicinity of deep roadway cut sections may be lowered. with a maximum cut of 20 feet, Alternative E is not anticipated to have a significant impact on ground water elevation. The approximate 40-foot cut section in Alternative A may result in a slight lowering of the water table. Alternative B, requiring approximately an 80-foot cut section, would be the most likely to adversely affect shallow wells close to the project. 4-22 ' 1 � � �J ' � , � , �1 Any effect on domestic water supply could be mitigated by the availability of municipal water service. A 16-inch water main from Boone currently crosses Alternative A to serve the industrial park. Water lines also extend approximately 1,000 feet east beyond Boone's town limits on US 421. Tentative plans for future expansion include extension of a 16-inch water main along US 421 to Bamboo Road, east of the South Fork New River. 4.5.4 Floodways and Flood Plains One ingression of right-of-way within the 100-year flood boundary has been identified; however, with proper drainage design, the impact will be minimal. The only regulatory floodway crossing will be at Hardin Creek, which is presently crossed by US 421 at the same location. Final design of, the culvert structure must ensure that the floodway will carry the 100-year flood without increasing the water surface elevation by more than 1 foot at any point. � ' � �J , � � � 4.5.5 Hydrology and Drainage One major stream, Hardin Creek, and one unnamed stream of lesser significance are unavoidably crossed by all alignments. At each hydrologic crossing, natural drainage patterns will be maintained and culvert structures used. Final design will ensure. that restriction of stream flow through these structures will not cause significant increases in flooding. 4-23 Discharge rates are anticipated to increase due to higher per- centages of impervious areas; however, any increase in flow rates will be attenuated by use of detention areas. Detention areas promote sedimentation of solids in addition to reduction of peak flows. Such an area may be necessary for discharge to Hardin Creek, as residents downstream frequently report flooding from present flows. Stream crossings and modifications will require permits from the U.S. Army Corps of Engineers (USACOE) and the North Carolina DNRCD. 4.5.6 Topography, Geology, and Soils The effect of the project on the study area's topography, geology, and soils varies with the amount of earthwork necessary for each of the alternative alignments. The greatest amount of earthwork is required by Alternative B and the least amount by Alternative E. Soil properties are common to all alternative alignments. Their non-cohesive and friable nature limits the angle of slopes and requires proper roadway design. Blasting for rock excavation may be required with Alternative B. Damage to adjacent properties from ground vibrations, tlyrock, and air pressure waves can be minimized by use of proper blasting procedures. 4.5.7. Hazardous Waste or Petroleum Storage Tanks The following hazardous waste or petroleum storage tank sites have been identified within the proposed right-of-way of the alternatives. 4-24 , � e � � ' � � ' � � Alternative E- One identified and three potential hazardous waste sites are located close to the existing US 421 alignment. The known site is: l. A previous gasoline service station, known as Fire Lines, on the northwest corner of US 421 and Grove Street. The potential sites are: l. �� Two gasoline service stations, Servco and Wilco, adjacent to and north of US 421, east of Highway 194. The aboveground storage tanks of the Appalachian Oil Company approximately 150 feet south of US 421 at SR 1596. The site of the converted service station at US 421 and Grove Street contains an underground storage tank and has been listed for remedial action funding from the North Carolina Leaking Underground Storage Tank (LUST) trust fund. At this time no schedule has been established for this funding action. ' Alternative A- The two-service stations on existing US 421 east of NC 194 and the converted service station at US 421 and Grove � Street are likely to be affected by this alignment. No additional sites in the vicinity of the northern alignment have obeen identified. ' iJ � � Alternative B- Potential hazardous waste sites associated with the southern alignment include the service station at the inter- section of US 421/NC 194 and an underground petroleum storage 4-25 tank, formerly used by the Coca-Cola distributor at the present location of Anchor Supply Company. The latter is close to the centerline of the proposed southern alignment. The hazardous waste site presently under assessment on US 421 at Grove Street is also common to this alignment. Conclusion Following alternative alignment selection and during right-of-way plan stage, the extent of disruption to the identified potential hazardous waste sites for the proposed highway construction will be determined. A site assessment will be performed (if necessary) to determine levels of contamination and evaluate corrective measures along with the necessary costs. Resolution of problems associated with hazardous materials will be coordinated with regulatory agencies. 4.6 NATURAL RESOURCES 4.6.1 Flora and Fauna The proposed project will result in some negative impacts to habitats within the alternative corridors. Although a signifi- cant amount of the surface area is composed of urban setting, loss of open area and field�and forest cover will reduce habitat for all animal species. There are no endangered, threatened, or special-concern plants in the area, but loss of older tree specimens subtracts from the seed source for future generations. This in turn reduces those biological factors required by all animal species. Biological impacts to be expected from vegetation removal within highway right-of-way include: 4-26 - Habitat modification from destruction of flora and fauna. - Loss of biological productivity in affected areas. - Imposition of physical barriers resulting in increased road kills. - Decreased percolation due to loss of biological surface area. - Increased surface runoff and erosion potential. Using aerial photographs and field measurements, the approximate acreage of wildlife habitat loss for each alternative corridor's right-of-way is estimated as shown in Table 4.9. Immediate, short-term impacts will result from the removal of vegetation and the rearrangement of the topical geography to accommodate new road cuts and roadbeds. Therefore, construction work areas should be restricted where practical, and proper precautions should be taken to limit erosion to the immediate work area. , Long-term impacts can be diminished by the use of selected � plantings as replacement of flora along highway rights-of-way. ' Rapidly growing indigenous species with good ground cover, varied understory, and varied crown cover will provide ample food and ' natural cover for the indigenous wildlife during all seasons of the year. Secondary succession will eventually replace unwise 1 selection of floral species. � � i il 4-27 TABLE 4.9 - APPROXIMATE ACREAGE OF WILDLIFE HABITAT LOSS FOR THE ALTERNATE RIGHTS-OF-WAY Alternative Alternative A Alternative B Alternative E Woodlands 1.9 0.4 0.4 . � Fields 4.2 6.1 1.9 Total 6.1 6.5 2.3 e � � � , ' lJ � lJ � � � � � � ' �I _J � ' �A major environmental impact will be the encroachment upon the South Fork New River in connection with relocation and expansion of the US 421 bridge. Strict adherence to erosion control standards must be a primary concern in this area. There are no known endangered, threatened, or special-concern species within the immediate construction area of the South Fork New River; however, any disturbance to this aquatic habitat will have repercussions for a significant distance downstream. An increased BOD load could result from disturbance to, and distribution of, bottom or bank organic materials accumulated through time and natural processes. This in turn may affect the dissolved oxygen levels available to the immediate downstream fauna. Increased siltation resulting from improperly controlled erosion within the project area will definitely adversely impact all gill-respiring species, both in the immediate area and for a significant distance downstream. Displacement of bottom-dwelling species is bound to occur as a short-term impact that will be mitigated through natural stream succession. Stream bank impacts resulting from vegetation removal can be resolved with replacement plantings of the appropriate indigenous species. 4.6.2 Threatened or Endangered Species Review of Federally Listed Species - Consultation with the U.S. Fish and Wildlife Service indicates that two threatened plant species and one threatened avian species may occur in the project !��%7 area, although the agency gave no indication of the locations of critical habitats. The species at issue are Heller's blazing star, Liatris helleri; the Blue Ridge goldenrod, Solidago spithamaee; and the American peregrine falcon, Falco peregrinus anatum. The following Status Review species may also occur in the project area: New England cottontail, Sylvilagus transitionalis; hellbender, Cryptobranchus alleganiensis; bog turtle, Clemmys muhlenbergi; Kanawha minnow, Phenacobius teretulus; bent avens, Geum geniculatum; spreading avens, Geum radiarum; white-leaved sunflower, Helianthus glaucophyllus; Gray's lilly, Lilium grayi; and Gray's saxifrage, Saxafraga carolinana. Other species listed for the State of North Carolina are not critical to the area of study.8 Review of State Listed Species - There is no official listing for the State of North Carolina, instead the state agencies use the federal lists. However, the North Carolina Natural Heritage Program has listed two plant species for special concern that may occur in the area of study: the wild mock cucumber, Echinocystis labata, and the crested shield fern, Dryopteris cristata.9 4.6.3 Prime and Important Farmlands Land currently available for agricultural use that would be taken for project construction was inventoried for each alignment. Table 4.10 shows the approximate acreage required for each alternative. 4-30 TABLE 4.10 PRIME AND IMPORTANT FARMLAND Alternative Alternative A Alternative B Alternative E � 4-31 Acres 4 4 1 4.7 VISUAL IMPACTS The construction of a new roadway or the upgrading of an existing road to additional lanes will have some visual impact on adjacent areas. It is necessary to provide adequate right-of-way that complies with required design criteria while disrupting the areas surrounding the right-of-way to the minimum extent possible. The issue is further complicated by the steep terrain and related limitations on construction in a mountainous area where it will be necessary to cut into mountain sides while filling other areas. Ridges and slope support will also be involved. This activity will create visual barriers and, should the design not receive proper attention, visual degradation. Therefore, it is important that the areas where cut/fill/bridges are required be studied, designed, and detailed to ensure an aesthetically acceptable visual quality. ' Visual impacts would be greatest along Alternative B because it would require the greatest cut at its eastern terminus. The other alternatives, with proper landscaping, should have minimal visual impacts. 4.8 ENERGY Construction of any of the improvement alternatives will consume energy; however, in the long-term, total energy utilization is expected to be reduced dramatically over the No-Build Alternative due to decreased vehicle delays and more efficient reliable operating speeds. 4-32 � � � 4.9 CONSTRUCTION IMPACTS 4.9.1 Water Quality ' Water quality may be temporarily affected by construction activi- ties at stream crossings and by erosion of unprotected slopes. ' The North Carolina Sedimentation Pollution Control Act of 1973 prohibits visible off-site sedimentation from construction sites. ' The law requires implementation of an approved plan, which ' includes temporary control measures for compliance. Erosion and sediment control measures that may be used to minimize � construction-related impacts are described in Federal Aid Highway Program Manual (FHPM) 6-7-3 and by the North Carolina DNRCD.10 , Those measures include scheduling construction activities to ' minimize the extent and duration of erosion hazards and use of temporary vegetation, mulching, sodding, sediment catch basins, ' silt fences, and diversion berms. Erosion control measures will be retained as permanent roadway design features whenever � possible. � � � � � � � 4.9.2 Air Quality Particulate matter or dust caused by heavy construction equipment and denuded earth can have an impact on local air quality, as can smoke caused by burning of cleared debris. Some measures to control air quality impacts from construction include: 4-33 - Implementation of sound erosion control measures to ensure that denuded earth is promptly covered with stabilizing material such as grass, mulch, or asphalt. - Covering of haul trucks. - Use of water as a dust controller. - Minimization of actual denuded areas. - Strict control of construction burning. CO and other pollutants contributed by automobiles may increase during construction due to resulting traffic delays. If proper traffic control measures are implemented, this should not be a significant problem. 4.9.3 Noise and Vibration Construction noise and vibration can be reduced through the development of a construction noise plan limiting the use of certain heavy vehicles during non-traditional work hours and days and enforcing the presence of properly working mufflers on construction equipment. Due to the urban setting in which this project is located, the use of blasting materials should be restricted. 4.10 IRREVERSIBLE AND IRRETRIEVABLE COMMITMENTS OF RESOURCES The construction of the preferred alternative of US 421 would require the following irreversible and irretrievable commitments of resources: 4-34 ' S- Use of land within the right-of-way exclusively for trans- � portation. - Possible encroachment on the biotic communities. O- Noise from construction and actual use of alternative corridor for nearby properties. ' - Commitment of manpower and resources for construction. ' ' ' � ' , � � ' � e ' � ' However, a long-term savings in resources, particularly fuel and amount of motorist time spent traveling, would be realized due to the more efficient roadway. This roadway improvement would also enhance long-term access opportunities and support the local and regional commitment to encourage the growth and economic viability of the Boone-Watauga County area. Thus, the commitcnent of resources to the building of the roadway will be exceeded by the savings in resources over time. 4.11 RELATIONSHIP BETWEEN SHORT-TERM IMPACTS AND LONG-TERM BENEFITS The short-term impacts would be limited to the actual construction of the roadway. During this time, traffic would be affected by temporary construction detours. Noise and vibrations from heavy construction equipment will be noticeable, especially from sites adjacent to the roadway corridor. Particulate matter and air quality impacts could be a short-term by-product of the construction. With a proper construction noise plan and erosion control measures these impacts will be minimized. 4-35 Existing homes and businesses will be displaced due to right-of- way requirements of the roadway. However, an analysis of the area showed that there are adequate replacement housing and business relocation opportunities. Even those workers in any businesses that are relocated should be able to retain their work but at the new locations. Water quality could be adversely affected on the short term. During construction, turbidity would be anticipated to increase in the small creeks that all of the alternatives pass through. This turbidity would also increase in the South Fork New River, into which these creeks feed. However, through the use of water quality control and erosion control measures, water quality would return to preconstruction levels. Construction of the preferred alternative improvement of US 421 would in the long term stimulate economic growth, save fuel and travel time, and reduce accidents. 4-36 , ' � ' ' � , ' CHAPTER 4 REFERENCES l.

This mailing list was used to send newsletters and correspondence concerning this Draft EIS. The names of approximately 90 individuals and organizations were collected. 6.2.2 Newsletters Two newsletters were prepared for this Draft EIS and sent out in February and April of 1989. Individuals on the computerized mailing list and local public officials received each of these newsletters, which are shown in Appendix B. The newsletters present information on the progress of the study as well as maps displaying alternatives under consideration. An additional newsletter will be prepared after submittal of the Draft EIS. 6.2.3 Toll-Free Hotline Phone Contact A toll-free phone number was established to make direct contact available for those individuals and organizations with questions C:�'� or comments. The Project Engineer and Project Manager from Hensley-Schmidt, Inc., were available at all times to answer the phone. Approximately 100 phone contacts were made through the toll-free phone number. 6.2.4 Small Group or Individual Informational Meetings Staff was available throughout the study process to meet with individuals and organizations on a one-to-one basis at the study area to answer questions. Several landowners in the study area took advantage of this opportunity. 6.2.5 Public Meetings/Worksho s Two public meetings/workshops were held at the Town of Boone Council Chambers on January 17 and May 18, 1989. Approximately 100 people attended the January 17 meeting, where officials from the NCDOT and Hensley-Schmidt, Inc., made a formal presentation, explained the EIS process, and presented the need for the project. At this meeting a written°questionnaire was distributed and over 40 responses were received. This questionnaire is shown in Table 6.2. The following comments were made through the questionnaire: - Thirty-nine individuals believed that an improvement to US 421 was needed. - The preference for the alternative corridor was almost evenly split among Alternative A, Alternative B, and Alternative E. . .

One archaeological site, 31Wt13, is located within the project area. However, the site has not been evaluated for significance nor has a systematic survey been conducted within the project.area to identify additional significant archaeological resources. We recommend that a comprehensive archaeological survey be conducted if Alternate B is selected. If Alternate A is selected, a survey is recommended for the eastern end only. We understand that HensleySchmidt, Inc., the project consultant, will conduct a cultural resources survey to identify and evaluate signif icant historic and prehistoric resources. Since a historic structures survey of Watauga County is currently under way, we sugoest that the project consultant contact Deborah Thompson, Center for Appalachian Studies, Appalachian State University, at 704/262-4089 (Tuesday or Thursday only) for information on any structures surveyed within the area of potential environmental effect. Our office looks forward to reviewing the survey results in the near future. The above comments are made pursuant to Section 106 of the National Historic Preservation Act of 1966, the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codif ied at 36 CFR Part 800, and to Executive Order 11593, "Protection and Enhance- ment of the Cultural Environment." 109 East Jones Screet • Raleigh, North Caroiina 27611 i , ' ' , , � ' ' ' � ' ' � � � ' � ' � J.

The Wildlife Resources Commission's biological field staff has reviewed the scoping letter on the proposed road project and can not make specific recommendations until final plans are presented for each proposed alternative route. However, in order to minimize impacts to the environment and wildlife habitats, we recommend that serious consideration be given to the alternative to improve the existing highway 421 roadway. Since the proposed project and alternatives will occur � in an area of urban development, we feel that an EIS addressing wildlife, wetlands and stream habitats will not be needed. We agree that impacts to streams and wetlands � will be minimal because the project will not cross these types of habitats. No endangered species .are known to exist in this project area. ' To pr�vent off-site damage to the South Fork New River located at the eastern edge of the project, standard DOT erosion control guidelines should be utilizeci. Erosion ' controls should be designed to withstand a 10 year storm (5 1/2 inches of rain in 24 hour period) as required by the St�tes' Sedimentation Act. When planning establish�ent of new vegetation, consideration should be given to utilizing ' some planting materials with greater benefits to wildlife. Adding white dutch or ladino clover to fescue and sericea lespedeza plantings will increase benefits to many wildife ' species.

In any proposed con- struction of a new roadway or significant improvement to an existing roadway, an analysis is needed to determine the relationship betveen the monetary benefits and costs to be derived from such an improvement. In addition to the economic analysis, a detailed assessment of the proposed development's impact on the environment is required, including natural cesources, histocic and architectural resources, archaeological conditions, socioeconomic and land use characteristics, displacement and relocations, traffic, air quality, and noise. � The North Carolina DepartJnent of Transpottation (NCDOT) and Hensley-Schmidt, Inc. are � accomplishing an E.I.S. for the proposed upgrading of US Route 421" from the ; intersection of S.R. 194 and US Route 421 to just vest of the South Fork New River Bridge. It vill be our job to determine what improvements are needed-to meet future anticipated traffic volumes, whether a nev alignment or an improvement of the existing roadvay will provide the most positive and least negative benefits, and the environmental consequences of each. Work is progressing and is expected to be rnmpleted on schedule, vith submission of a Draft Environmental Impact Statement for reviev in mid 1989. The Draft Environmental Impact Statement vill describe the possible alternatives for improvement of US Route 421 and theit respective impacts on the environment and economic benefits. TELEPHONE HOTLINE To better provide information and to ansWer questions concerning the proposed improve- ments to US Route 421 and the Environmental Impact Statement progress, a toll free telephone number has been established for citizens' direct comnunication to the Hensley-Schmidt, Inc. engineecs. The toll free number is available foc project calls from 8:30 a.m. to 5:30 p.m. Monday thcough Friday.

Enclosed in this newsletter is a map showing all of the possible corridoc segments numbered from 1 to 4. � The success of this first public meeting is obvious by the infocmation learned by the engineers. The location of several potential histocic and archaeological sites, including cemeteries, was pointed out to us by local citizens. WHAT NEXT � Utilizing cortments and cecommendations received from the ficst public meeting the many possible alternative alignment corridors as shown at that meeting Will be reduced in numbec by eliminating those that are determined to be impcactical due to enviconmental impact oc cost. The end result of this process Will be the establishment of the preliminary alternatives. These pceliminacy alternatives would then be studied in detail for environmental impacts, construc.tion costs, and traffic handling characteristics. In addition to the study of these alternatives vill be the "do nothing" alternative, and an upgrading and improving of existing US Route 421 alignment. Once the study alternatives are established another neNSletter Will be sent out to inform you of the ones vhich are selected. Another public meeting Will also be held in late Spring for public presentation and feedback on the findings of the environmental impacts, construction costs, and traffic handling chacacteristics of each selected alternative.

Upon review and approval by the public and the required public officials, a recommendation will be made. The preliminacy E.I.S. submittal is scheduled for late June, 1989. PROGRESS OF THE STUDY , Work has progressed from our last public meeting in most aspects of the study. Fram our last public meeting where all of the possible study routes were presented, we have narrowed down the number to two Alternative Corridor Routes, Improve Existing Corridor, and the No-Build Alternative. These routes are all presented in the schematic on the back page of this newsletter. Due to the unusually wet winter, some aspects of the study such as historic, architectural, and archaeological field work have been delayed. The review of the flora and fauna (plants and animals) must wait until the beginning of wacm weather. Other than these aspects of the study, the remaining study topics such as the economic analysis, socio-economic and land use characteristics, number of displacements and relocations, traffic, air quality, and noise analysis are all nearing completion with results to be presented at the upcoming public meeting. Following is a brief description of selected study topics and what has happened in each. .NOISE - Hensley-Schmidt, Inc. personnel were in the Boone area during the week of April lOth to measure existing noise levels at selected locations. The measurement of existing noise levels is used to help detecmine future noise levels for each of the Alternatives. The Federal Highway Administration (FHWA) has determined that noise levels should not exceed 65 dBA for residences and 70 d9A foc Cortme[cial areas. To help in understanding these levels the figure on the right below shows characteristic . I10132 levels for different activities.

AlR The impact resulting from the construction of a new highway or the improvement of an existing highway can range from aggravating existing air pollution problems to improving the ambient air conditions. In order to ensure that any proposed improve- ment or construction of a roadway will not adversely affect the health of the general public, the FHWA has estatilished ambient air quality standards (i.e. allowable pollutant parts per million) for all pollutants. The pollutants that are most produced by automobiles are carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides. Preliminary study results show that no adverse air quality should be experienced from any of the alternatives. _.OTHER _ _____ Results from other study topics are being finalized as of this newsletter. Within the next couple of weeks you should see more and more of our personnel in your area taking measurements and readings of every type imaginable. By the time of our next public meeting all of our results shall be in for your review and comments. REMEMBER— - Our Toll Free Number is 1-800-242-0421 Hensley-Schmidt, Inc. P. O.
