Attached for your information is a copy of the project planning document for the subject project prepared by the North Carolina Department of Transportation (DOT) and signed by the Federal Highway Administration (FHWA) on October 31, 1996. The project involves replacing Bridge No. 82 over Clark Creek on SR 1165. The new bridge will be placed on existing alignment. During project construction, traffic will be maintained using an off site detour. No jurisdictional wetlands will be impacted by the subject project. The project is being processed by the FHWA as a "Categorical Exclusion" (CE) in accordance with 23 CFR 771.115(b). Therefore, the DOT does not anticipate requesting an individual permit but proposes to proceed under a Nationwide Permit 23 in accordance with 33 CFR 330 Appendix A (B-23) issued December 13, 1996, by the Corps of Engineers (COE). The provisions of Section 330.4 and Appendix A (C) of these regulations will be followed in the construction of the project. The DOT anticipates that 401 Gene I ter Quality Certification for an approved CE will apply to this project. A copy of a CE d cument has also been provided to the North Carolina Department of Environme t, Hea h and Natural Resources, Division of Water Quality, for their review.

No. B-2940 Bridge No. 82 is included in the North Carolina Department of Transportation (NCDOT) 1997- 2003 Transportation Improvement Program. The location is shown in Figure 1. No substantial impacts are anticipated as a result of this action. The project is classed as a Federal "Categorical Exclusion." 1. SUMMARY OF ENVIRONMENTAL COMMITMENTS 1. All Standard procedures and measures, including NCDOT's Best Management Practices for Protection of Surface Waters, will be implemented, as applicable, to avoid or minimize environmental impacts. 2. Construction will be scheduled to include the summer months to minimize impacts on school bus traffic. 3. Location and installation of any required deck drains will be determined during final design phase. II. SUMMARY OF RECOMMENDATIONS Bridge No. 82 will be replaced on the existing alignment as shown in Figure 2. It will be replaced with a new bridge having a clear roadway width of 9.2 meters (30 ft) and a length of 46 meters (151 ft). The grade of the new structure will be approximately the same as the existing bridge grade at this location. A vertical design exception will be required. The proposed approach roadway will have a 7.2 meter (24 ft) travelway with 2.4 meters (8 ft) shoulders, including 0.6 meter (2 ft) paved, for approximately 110 meters (360 ft) east and west of the bridge. During construction, traffic will be detoured off-site as shown in Figure 1. The estimated cost, based on current prices, is $961,000 including $61,000 for right-of-way and $900,000 for construction. The estimated cost of the project, as shown in the NCDOT 1997- 2003 Transportation Improvement Program, is $450,000 including $30,000 for right-of-way and $420,000 for construction. III. EXISTING CONDITIONS SR 1165 is classified as a rural collector route in the Statewide Functional Classification System. Land use is primarily residential, forest land and agricultural in the immediate vicinity of the bridge. Bridge No. 82 is located approximately 215 meters (700 ft) downstream from the confluence of Cline Creek and Clark Creek. The existing bridge is located in a vertical sag with an approximate 9 percent grade on the west approach and an approximate 4 percent grade on the east approach. A design exception for the vertical alignment will be required. Near the bridge SR 1165 is tangent and has a 5.9 meter (19.2 ft) pavement width and 1.8 meter (6 ft) shoulders. Both approaches are constructed on 7.0 meter (23 ft) embankments. The surface of the bridge is approximately 9.0 meters (29.5 ft) above the creek bed. The speed limit is posted 70 km/h (45 mph) at the project site and the existing northwest approach curve has an advisory speed of 55 km/h (35 mph). SR 1165 is a connector between SR 1005 and SR 1149, minor arterials for Hickory and Conover, respectively. These minor arterials serve area which are beginning to undergo suburbanization. The thoroughfare plan for the Cities of Hickory, Newton and Conover show the proposed Newton-Conover Southern Loop (T.I.P. No. U-2532) will use the existing SR 1165 alignment. Construction of the Southern Outer Loop is scheduled to begin between 2015 and 2025. When the Southern Loop is completed and open to traffic, the section which includes this bridge is expected to carry 15,800 vehicles per day (vpd). Prior to construction of the Southern Loop, the projected traffic volume are 2,700 vpd for 1997 and 6,200 vpd for the design year 2017. The proposed bridge replacement project is based on design traffic volumes prior to the construction of the Southern Loop. The volumes include one percent truck-tractor semi-trailer (TTST) and two percent dual-tired vehicles (DT), twelve percent design hourly volume and fifty- five percent directional. The existing bridge was built in 1960 (Figure 3). The superstructure consists of timber deck on steel 1-beams with an asphalt wearing surface. The substructure consists of timber caps and piles with cross bracing and vertical timber bulkheads at the abutments. The overall length of the bridge is 46.0 meters (151 ft). The clear roadway width is 5.9 meters (19.2 ft). The posted weight limit is 12,712 kilograms (14 tons) for single vehicles and 16,344 kilograms (18 tons) for truck-tractor semi-trailers. Bridge No. 82 has a sufficiency rating of 42.2, compared to a rating of 100 for a new structure. Four accidents were reported on the bridge during the period from April 1, 1992 to March 31, 1995. Two accidents were double vehicle with icy conditions. Two accidents were single vehicle accidents, one in icy conditions, the other exceeding the speed limit. All accidents involved loss control of the vehicle According to Catawba County Planning Department, there is a 24-inch sewer line on the east side of the bridge. An overhead electric power line is on the north side of the bridge. An overhead telephone line crosses SR 1165 to the west of the bridge. Utility impacts are anticipated to be low. Three Catawba County school buses cross the bridge twice daily. IV. ALTERNATIVES Several preliminary alternatives were studied for replacing Bridge No. 82 including replacement with a bridge or a culvert. Economical analysis eliminated the option of replacing the bridge with a culvert due to fill heights and size of the culvert. The bridge alternatives studied for replacing Bridge No. 82 include a new bridge 46.0 meters (151 ft) in length, that will accommodate a 7.2 meter (24 ft) travelway with 1.0 meter (3 ft) shoulders on each side. The approach roadway consists of a 7.2 meter (24 ft) travelway with 2.4 meter (8 ft) shoulders, including 0.6 meter (2 ft) paved shoulders. Alternate A: Replace the bridge on existing alignment with a temporary on-site detour bridge on the south side. The roadway grade of the new structure will be approximately the same as the grade on the existing bridge. The approach work will extend approximately 110 meters (360 ft) east and west of the proposed bridge. A vertical design exception will be required. The detour bridge will require a length of 30 meters (99 ft). Alternate B (Recommended): Replace Bridge No. 82 will be replaced on existing alignment at approximately the same elevation. Traffic will be detoured off-site along existing roads during construction. The approach work will extend approximately 110 meters (360 ft) east and west of the proposed bridge. A vertical design exception will be required. Other Alternates: The "do-nothing" alternative would eventually necessitate closure of the bridge. This is not desirable due to the traffic service provided by SR 1165. Investigation of the existing structure by the Bridge Maintenance Unit indicates the rehabilitation of the old bridge is not feasible due to its age and deteriorated condition. 3 V. ESTIMATED COST The estimated costs of the alternate studied, based on current prices, are as follow: Alternate A Structure Removal (existing) $ 18,240 Structure (proposed) 296,240 Temp. Detour Structure and Approaches 338,800 Roadway Approaches 275,020 Miscellaneous and Mobilization 296,700 Engineering and Contingencies 175,000 ROW/Const. Easements/Utilities 68,000 TOTAL $ 1,468,000 VI. TRAFFIC DETOUR (Recommended) Alternate B $ 18,240 296,240 N/A 275,020 185,500 125,000 61,000 $ 961,000 An eight month road closure period is anticipated. Traffic will be detoured along SR 1149 and SR 1005, an approximate distance of 5.0 kilometers (3.1 miles). The detour roadway and bridges are adequate to accommodate the detoured traffic during the construction period. Provision of an on-site detour is not justifiable due to added cost incurred by the extensive fill heights and length of detour structure. Construction will be scheduled to include the summer months to minimize impacts on school bus traffic. VII. RECOMMENDED IMPROVEMENTS Alternate B is recommended because it is the most economical. Bridge No. 82 will be replaced on the existing alignment at approximately the same elevation with a length of 46 meters (151 ft). A vertical design exception will be required. A 9.2 meter (30 ft) clear roadway width is recommended on the replacement structure in accordance with the current NCDOT Bridge Policy. This will provide a 7.2 meter (24 ft) travelway with 1 meter (3 ft) shoulders across the structure. A 7.2 meter (24 ft) travelway with 2.4 meter (8 ft) shoulders, including 0.6 meter (2 ft) paved, will be provided on the proposed approaches. The Division Engineer concurs in the recommendation that the structure be replaced on the existing alignment with SR 1165 closed during construction and traffic detoured along other existing roads. 4 Based on a preliminary hydraulic analysis utilizing the 25 year design storm, the new structure is recommended to have a length of approximately 46 meters (151 ft). The elevation of the new structure will be approximately the same as the existing bridge. The replacement structure will maintain a minimum 0.3% grade to facilitate deck drainage. The length and height may be increased or decreased as necessary to accommodate peak flows as determined by further hydrologic studies. VIII. ANTICIPATED DESIGN EXCEPTION A vertical design exception for the design speed will be required due to the existing vertical alignment. The existing vertical design speed is approximately 60 km/h (35 mph), which is within the character of SR 1165. The speed limit is posted 70 km/h (45 mph) at the project site. Improving the vertical alignment to a design speed of 80 km/h (50 mph) will require raising the grade approximately 1.8 meters (6 ft). This was not considered reasonable due to the additional environmental impacts, right-of-way and construction costs, and major changes to the vertical alignment. IX. NATURAL RESOURCES The proposed project is located within rural Catawba County (Figure 1) in the Piedmont Physiographic Province of North Carolina. Catawba County is primarily agricultural but is rapidly becoming an industrial and urban county. Methodology Informational sources used to prepare this report include: United States Geological Survey (USGS) quadrangle map (Hickory, 1970); NCDOT aerial photographs of project area (1:1200); Soil Conservation Service (SCS) soil maps (1975); Fish and Wildlife Service (FWS) National Wetlands Inventory Map (Hickory, 1994); FWS list of protected and candidate species; and North Carolina Natural Heritage Program (NCNHP) database of uncommon species and unique habitats. Research using these resources was conducted prior to the field investigation. A general field survey was conducted along the proposed project corridor on March 20, 1996. Plant communities and their associated wildlife were identified using a variety of observation techniques, including active searching, visual observations with binoculars, and identifying characteristic signs of wildlife (sounds, tracks, scat, and burrows). Quantitative impact calculations were based on the worst case scenario using the full 24.4 m (80.0 ft) wide right-of-way limits and the width of the replacement structure, the width of the stream for aquatic impacts, and the length of the project approaches. The actual construction impacts should be less, but without specific replacement structure design information (culvert, pier intrusions, etc.) the worst case was assumed for the impact calculations. Definitions for area descriptions used in this report are as follows: "project study area," "project area," and "project corridor" denote the specific area being directly impacted by each alternative. "Project vicinity" denotes the area within a 1.6 km (1.0 mi.) radius of the project area. 5 Topography and Soils The topography of the project vicinity is characterized as rolling hills with steeper slopes along the major streams. Project area elevation is approximately 268.2 meters (880.0 feet). This portion of Catawba County contains soils from the Hiwassee-Cecil association, which are characterized as being gently sloping to moderately steep soils that have a subsoil that is dominantly dark-red or red, firm clay found on broad ridgetops and short side slopes. The field investigation confirms the soils as they are mapped. WATER RESOURCES This section describes each water resource and its relationship to major water systems. The proposed project lies within the Catawba River drainage basin. Water Resource Characteristics Clark Creek is a perennial tributary within the Catawba River basin. The stream banks are well defined, approximately 3.0 meters (10.0 feet) high, and vegetated with river birch, ironwood (carpinus caroliniana), greenbrier and blackberry. The stream flows north to south through the proposed project area with a width at the bridge of 10.1 meters (33.0 feet). On the day of investigation the stream was turbid and the bottom was only visible in a few shallow areas. The bottom consists of medium to coarse gravel covered with silt. The depth of the stream could not be accurately determined due to the turbidity and the swift flow. Clark Creek has a Class C rating and a stream index no. of 11-129-5-(4.5) from the NCDEM, indicating the creek's suitability for aquatic life propagation and survival, fishing, wildlife, secondary recreation, agriculture, and other uses. The Federal Emergency Management Agency (FEMA) Flood Boundary and Floodway Map for Catawba County (1980) indicates the project area lies in Zone AE where base flood elevations have been determined. The base flood elevation at Bridge No. 82 is 262.4 meters (861.0 feet). The NCDEM does maintain a benthic macroinvertebrate sampling station on Clark Creek downstream of the project area. Benthic macroinvertebrates, or benthos, are organisms that live in and on the bottom substrates of rivers and streams. The use of benthos data has proven to be a reliable tool as some benthic macroinvertebrates are sensitive to subtle changes in water quality. Criteria have been developed to assign bioclassifications ranging from "Poor" to "Excellent" to each benthic sample based on the number of taxa present in the intolerant groups Ephemeroptera, Plecoptera and Tdchoptera (EPT). Different criteria have been developed for different ecoregions (mountains, piedmont, coastal) within North Carolina. Data from Clark Creek at SR 1149 in August 1992 indicated an EPT taxa richness value of 16, which has a bioclassification of "Good-Fair". The NCDEM also uses the North Carolina Index of Biotic Integrity (NCIBI) as another method to determine general water quality. The method was developed for assessing a stream's biological integrity by examining the structure and health of its fish communities. The scores derived from the index are a measure of the ecological health of the waterbody and may not necessarily directly correlate to water quality. There is no NCIBI data for Clark Creek. The Catawba County Watershed Protection District Ordinance (1993) provides regulations to limit the exposure of watersheds in Catawba County to pollution. The Critical Area is defined as being one-half mile from a lake or where water is taken from a river. The critical area is the area closest to the drinking water source. Regulations restrict development in this area. The Protected Area is the remainder of the watershed where the regulations apply. The Watershed Protection District Map indicates that the project area is not within a Critical Area. No waters classified by NCDEM as High Quality Waters (HQW), Outstanding Resource Waters (ORW), or waters designated as WS-1 or WS-II are located within 1.6 km (1.0 mile) of the project study area. No impacts to sensitive water resources of any kind will take place as a result of the project construction. Anticipated Impacts to Water Resources Short-term impacts to water quality can be anticipated from construction-related activities, which may increase sedimentation and turbidity. Short-term impacts will be minimized by the implementation of NCDOT's Best Management Practices for Protection of Surface Waters, as applicable. Long-term impacts to water resources are not expected as a result of proposed improvements. BIOTIC RESOURCES Living systems described in the following sections include communities of associated plants and animals. These descriptions refer to the dominant flora and fauna in each community and the relationship of these biotic components. Scientific nomenclature and common names (when applicable) are used for the plant and animal species described. Subsequent references to the same species include the common name only. Terrestrial Communities The predominant terrestrial communities found in the project study area are man-dominated and mixed hardwood forest. Dominant faunal components associated with these terrestrial areas are discussed under the community description. Many species are adapted to the entire range of habitats found along the project alignment, but may not be mentioned separately in each community description. Man-Dominated Community This highly disturbed community includes the road shoulders, the powerline easement, the pastures to the southeast and southwest of the bridge, and the open grassy field to the northeast of the bridge (Figure 2). These regularly maintained areas are dominated by fescue (Festuca sp.), ryegrass (Lolium sp.), white clover (Trifolium repens), thistle (Cirsium sp.), broomsedge (Andropogen virginicus), wild onion (Allium canadense), violet (Viola sp.), and dandelion (Taraxacum offrcinale). The animal species present in these disturbed habitats are opportunistic and capable of surviving on a variety of resources, ranging from vegetation (flowers, leaves, fruits, and seeds) to living and dead faunal components. Virginia opossum (Didelphis virginiana), American crow (Corvus brachyrhynchos), and Northern cardinal (Cardinalis cardinalis) were observed during the site visit. Other animals such as mice (Peromyscus sp.), the Northern mockingbird (Mimus polyglottos), and the American robin (Turdus migratodus) are also often attracted to these roadside habitats. Mixed Hardwood Community This forested community occurs on the moderate slopes along Clark Creek as well as in narrow strips in the pastures and field. The dominant canopy trees in this area include river birch (Betula nigra), loblolly pine (Pinus taeda), southern red oak (Quercus falcata), red maple (Acer rubrum), white oak (Quercus albs), Eastern red cedar (Juniperus virginiana), post oak (Quercus stellata), and sweetgum (Liquidambar styraciflua). The herbaceous layer consists mainly of Japanese honeysuckle (Lonicera japonica), common greenbder (Smilax rotundifolia), blackberry (Rubus sp.), and giant cane (Arundinaria gigantea). Gray squirrel (Sciurus carolinensis), raccoon (Procyon lotor), and mourning dove (Zenaida macroura) were observed during the site visit. Although not observed during the site visit, the animals previously listed may be found in this community along with whitetail deer (Odocoileus virginianus), Eastern cottontail (Sylvilagus floridanus), downy woodpecker (Picoides pubescens), Carolina wren (Thryothorus ludovicianus), and Eastern box turtle (Terrapene carolina carolina). Aquatic Communities The aquatic community in the project area exists within Clark Creek. Animals such as the Northern water snake (Nerodia sipedon sipedon), the bullfrog (Rana catesbeiana), and the Southern leopard frog (Rana utricularia) may reside along the waters edge. The macroinvertebrate community of this stream would include mayfly (Ephemeroptera), stonefly (Plecoptera), caddisfly (Trichoptera) and dragonfly (Odonata) larvae under stones and within the leaf debris as well as chironomid (midges) larvae and oligochaetes (segmented worms) within the substrate. No macroinvertebrates were observed during the site visit. According to the North Carolina Wildlife Resources Commission (Memorandum dated April 10, 1996), the following fish species were collected in Clark Creek in 1993: bluehead chub (Nocomis leptocephalus), white sucker (Catostomus commersoni), flat bullhead (Ameiurus platycephalus), redbreast sunfish (Lepomis auritus), pumkinseed (Lepomis gibbosus), bluegill (Lepomis macrochirus), and large mouth bass (Micropte?us salmoides). Anticipated Impacts to Biotic Communities Biotic community impacts resulting from project construction are addressed separately as terrestrial impacts and aquatic impacts. Table 1 details the anticipated impacts to terrestrial and aquatic communities by habitat type. However, impacts to terrestrial communities, particularly in locations exhibiting steep slopes, can result in the aquatic community receiving heavy sediment loads as a consequence of erosion. The NCDOTs Best Management Practices for Protection of Surface Waters, will be implemented, as applicable, to ensure sediment does not leave the construction site. 8 TABLE 1 ANTICIPATED IMPACTS TO TERRESTRIAL and AQUATIC COMMUNITIES HECTARES(ACRES) Bridge #82 Man- Mixed Aquatic Combined Total Replacement Dominated Hardwood Community Impacts Community Community Alternative A 0.25 (0.62) 0.06 (0.16) 0.02 (0.05) 0.33 (0.83) Temporary 0.40 (1.0) 0.04 (0.10) 0.02 (0.05) 0.46(l.16) Detour Alternative B 0.25 (0.62) 0.06 (0.16) 0.02 (0.05) 0.33 (0.83) Recommended Impacts to Terrestrial Communities Of the two communities in the project area, greatest impact from construction, resulting in and mortality of faunal species in residence. the man-dominated community will receive the the loss of existing habitats and displacement Impacts to Aquatic Communities The aquatic community in the study area exists within Clark Creek. The proposed bridge replacement may result in the disturbance of up to 0.02 hectare (0.05 acre) of stream bottom. The new replacement structure construction and approach work will likely increase sediment loads in the stream in the short term. Construction related sedimentation can be harmful to local populations of invertebrates which are an important part of the aquatic food chain. The impacts to the stream community will not be confined to the 0.02 hectare (0.05 acre) impact zone. Potential adverse effects will be minimized through the implementation of NCDOT's Best Management Practices for Protection of Surface Waters, as applicable, and the use of erosion and sediment control measures as specified in NCDOT Erosion and Sedimentation Control Guidelines for Contract Construction (January 1995)". SPECIAL TOPICS Jurisdictional Issues Waters of the United States Wetlands and surface waters fall under the broad category of "Waters of the United States" as defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean Water Act (33 U.S.C. 1344) and are regulated by the U.S. Army Corps of Engineers (USACOE). Impacts to Wetlands and Surface Waters 9 No wetlands will be impacted by the subject project as Clark Creek has well defined banks within the bridge replacement corridor. Investigation into wetland occurrence in the project area was conducted using methods of the 1987 Wetland Delineation Manual. Project construction cannot be accomplished without infringing on jurisdictional surface waters. Up to 0.02 hectare (0.05 acre) of jurisdictional surface water impacts may occur due to the proposed replacement of Bridge No. 82. Permits Nationwide Permit No. 23 CFR 330.5(a)(23) is likely to be applicable for all impacts to Waters of the United States from the proposed project. This permit authorizes activities undertaken, assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency or department where: 1) that agency or department has determined the pursuant to the council on environmental quality regulation for implementing the procedural provisions of the national Environmental Policy Act; 2) that the activity, work, or discharge is categorically excluded from environmental documentation because it is included within a category of actions which neither individually nor cumulatively have a significant effect on the human environment, and; 3) that the office of the Chief of Engineers has been furnished notice to the agency's or department's application for the categorical exclusion and concurs with that determination. The NCWRC made several potential recommendations pertaining to the permit application for this project in a April 10, 1996, memorandum (Appendix). The recommendations as applicable, will be implemented in accordance with NCDOT's Best Management Practices for Protection of Surface Waters. Mitigation Since this project will not impact jurisdictional wetlands, compensatory mitigation will not be required. Mitigation requirements on projects covered by Nationwide permits are left up to the discretion of the USACOE. Rare and Protected Species Some populations of plants and animals have been in or are in the process of decline either due to natural forces or due to their inability to coexist with man. Rare and protected species listed for Catawba County, and any likely impacts to these species as a result of the proposed project construction, are discussed in the following sections. Federally Protected Species Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7 10 and Section 9 of the Endangered Species Act of 1973, as amended. The USFWS lists one federally protected species for Catawba County as of August 23, 1996, (see Table 2). TABLE 2 FEDERALLY-PROTECTED SPECIES FOR CATAWBA COUNTY Scientific Name Status (Common Name) Hexastylis naniflora T (Dwarf-flowered heartleaf) NOTE: T Denotes Threatened (a species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range). The dwarf-flowered heartleaf is a perennial, evergreen herbaceous plant having the aroma of ginger. The leaves of the dwarf-flowered heartleaf are variegated, cordate to orbicular-cordate and approximately 4.0 to 6.0 cm (1.6 to 2.4 inches) long and wide. The flowers have a cylindrical calyx tube with an apical flare which is wider than the calyx tube is long. The flowers are present between late March and June. The dwarf-flowered heartleaf is often found in mature, deciduous forests on acidic, sandy loam soils of north facing bluffs and ravines. It is frequently associated with mountain laurel, and with Pacolet sandy loam soil of the Piedmont physiographic province. No habitat exists in the project area as the project area does not contain acidic, sandy loam soil or north facing slopes. It can be concluded that the proposed project will not impact this Threatened species. BIOLOGICAL CONCLUSION: NO EFFECT Federal Species of Concern Federal Species of Concern (FSC) are not legally protected under the Endangered Species Act and are not subject to any of its provisions, including Section 7, until they are formally proposed or listed as Threatened of Endangered. Species designated as FSC are defined as taxa which may or may not be listed in the future. These species are formerly Candidate 2 (C2) species, or species under consideration for listing for which there is insufficient information to support listing. NCNHP database showed no recorded occurrences of state protected species within the project vicinity. Table 3 includes FSC species listed for Catawba County and their state classifications. 11 TABLE 3 FEDERAL SPECIES OF CONCERN CATAWBA COUNTY Scientific Name North Carolina Habitat Present (Common Name) Status Dactyloctythere isabelae N/L No (Catawba crayfish ostracod) Monotropsis odorata C Yes (Sweet pinesap) NOTES: C Denotes Candidate species are considered by the State as being rare and needing population monitoring. N/L Denotes species for which the state status is not listed at this time. State Protected Species Plant and animals which are listed as Endangered (E), Threatened (T), or Special Concern (SC) by the NCNHP list of Rare Plant and Animal species are afforded limited state protection under the State Endangered Species Act and the North Carolina Plant Protection and Conservation Act of 1979. The NCNHP records indicated two state-listed Special Concern species, highfin carpsucker (Carpiodes velifer) and loggerhead shrike (Lanius ludovicianus ludovicianus). A search of the NCNHP database showed no recorded occurrences of state protected species within the project vicinity and no individuals were observed during the investigation. X. CULTURAL EFFECTS This project is subject to compliance with Section 106 of the National Historical Preservation Act of 1966, as amended, implemented by the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106, codified at 36 CFR Part 800. Section 106 requires that for federally funded, licensed, or permitted projects having an effect on properties listed in or eligible for the National Register of Historic Places, the Advisory Council on Historic Preservation be given the opportunity to comment. In a Concurrence Form, dated April 11, 1996, the State Historic Preservation Officer (SHPO) concurred that there are no historic architectural resources either listed in or eligible for listing in the National Register of Historic Places located in the project's area of potential effect. A copy of the SHPO letter is included in the Appendix. The SHPO, in a memorandum dated April 4, 1996, stated there are no known archaeological sites within the proposed project area and therefore, SHPO recommended that no archaeological investigation be conducted in connection with this project. A copy of the SHPO memorandum is included in the Appendix. 12 XI. ENVIRONMENTAL EFFECTS The project is expected to have an overall positive impact. Replacement of an inadequate bridge will result in safer traffic operations. The bridge replacement will not have an adverse effect on the quality of the human or natural environment with the use of current NCDOT standards and specifications. The project is not in conflict with any plan, existing land use, or zoning regulation. No significant change in land use is expected to result from construction of the project. No adverse impact on families or communities is anticipated. No relocatees are expected with implementation of the proposed alternatives. No adverse effect on public facilities or services is anticipated. The project is not expected to adversely affect social, economic, or religious opportunities in the area. There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of national, state, or local significance in the vicinity of the project. No geodetic survey markers will be impacted. The Farmland Protection Policy Act requires all federal agencies or their representatives to consider the potential impacts to prime and important farmland soils by all land acquisition and construction projects. Prime and important farmland soils are defined by the U.S. Soil Conservation Service (SCS). Since the bridge will be replaced at the existing location, the Farmland Protection Policy Act does not apply. This project is an air quality "neutral" project, so it is not required to be included the regional emission analysis (if applicable) and a project level CO analysis is not required. The project is located in Catawba County, which has been determined to be in compliance with the National Ambient Air Quality Standards. 40 CFR Part 51 is not applicable because the proposed project is located in an attainment area. This project is not anticipated to create any adverse effects on the air quality of this attainment area. The traffic volumes will not increase or decrease because of this project. There are no receptors located in the immediate project area. The projects impact on noise and air quality will not be significant. Noise levels could increase during construction but will be temporary. If vegetation is disposed of by burning, all burning shall be done in accordance with applicable local laws and regulations of the North Carolina SIP air quality in compliance with 15 NCAC 2D.0520. This evaluation completes the assessment requirements for highway traffic noise (23 CFR Part 772) and for air quality (1990 CAAA and NEPA) and no additional reports are required. An examination of records at the North Carolina Department of Environment, Health and Natural Resources, Division of Environmental Management, Groundwater Section and the 13 North Carolina Department of Human Resources, Solid Waste Management Section revealed no underground storage tanks or hazardous waste sites in the project area. Catawba County is a participant in the National Flood Insurance Program. The approximate 100 year floodplain in the project area is shown in Figure 4. The amount of floodplain area to be affected is not considered to be significant. On the basis of the above discussion, it is concluded that no significant adverse environmental effects will result from implementation of the project. The project is a Federal "Categorical Exclusion" due to its limited scope and lack of significant environmental consequences. 14 REFERENCES Burt, W.H. and R.P. Grossenheider. 1952.

Region Coordinator Habitat Conservation Program DATE: April 10, 1996 SUBJECT: Comments on Group IX Bridge Replacements, Alleghany, Cleveland, McDowell, Buncombe, and Catawba Counties. This correspondence responds to a request by you for our review and comments regarding eleven proposed bridge replacements in western North Carolina. Biological field staff of the North Carolina Wildlife Resources Commission (WRC) have reviewed the information in your letter dated 11 March 1996 and have examined our records fish sampling data. Our comments on these projects are listed below. All species and common names follow "Common and Scientific Names of Fishes from the United States and Canada" by Robins et al. 1991 (American Fisheries Society Special Publication 20). Species listed in bold print are considered to be intolerant to stream degradation under the North Carolina Index of Biotic Integrity used by the North Carolina Division of Environmental Management to assess the biological integrity of streams. B-2803 - Alleghany County, Bridge No. 52 over Little River, Bridge No. 56 over Pine Swamp Creek Both the Little River and Pine Swamp Creek are designated Hatchery Supported Public Mountain Trout Waters (PMTW) in the project area. We recently provided you with a memorandum dated 12 July 1995 with our scoping comments on this project (see attached). B-2815 - Cleveland County, Bridge No. 35 on SR 1001 over Persimmon Creek No fish data are available for Persimmon Creek, nor have we identified any special concerns associated with this project. B-2816 - Cleveland County, Bridge No. 230 on SR 1908 over Buffalo Creek We have not identified any special concerns associated with this project. According to WRC district files, the following fish species were collected in Buffalo Creek in 1980: Group IX Page 2 April 10, 1996 Common Name rosyside dace bluehead chub greenfin shiner spottail shiner yellowfin shiner swallowtail shiner sandbar shiner creek chub striped jumprock redbreast sunfish bluegill Scientific Name Canostomus funduloides Nocomis leptocephalus Cyprinella chloristius Notropis hudsonius Notropis lutipinnis Notropis procne Notropis scepticus Semotilus atromaculatus Moxostoma rupiscartes Lepomis auritus Lepomis macrochirus Other species collected by Messer et al. of the WRC in 1964: gizzard shad Dorosoma cepe&anum rainbow trout Oncorhynchus mykiss fieryblack shiner Cyprinella pyrrhomelas highback chub Notropis hypsinotus white sucker Catostomus commersoni redhorse Moxostoma sp. bullhead Ameiurus sp. pumpkinseed Lepomis gibbosus warmouth Lepomis gulosus largemouth bass Micropterus salmoides B-2847 - McDowell County, Bridge No. 65 on SR 1760 over Muddy Creek We have not identified any special concerns associated with this project. No fish sampling data is available for Muddy Creek, but we would expect the species assemblage to be similar to that of South Muddy Creek (see B-3002 below). B-2931 - Buncombe County, Bridge No. 512 on SR 2435 over Swannanoa River The Swannanoa River is designated Hatchery Supported PMTW at the project site. The river also supports some wild trout. We would prefer that the existing bridge be replaced with another spanning structure. B-2940 - Catawba County, Bridge No. 82 on SR 1165 over Clark Creek We have not identified any special concerns associated with this project. Schneider of the North Carolina Division of Environmental Management (DEM) collected the following fish species in Clark Creek in 1993: Common Name Scientific Name bluehead chub Nocomis leptocephalus white sucker Catostomus commersoni flat bullhead Ameiurus platycephalus Group IX redbreast sunfish pumpkinseed bluegill largemouth bass B-2941 - Catawba Cou Page 3 April 10, 1996 Lepomis auritus Lepomis gibbosus L Momis macrochirus Micropterus salmoides nty, Bridge No. 94 on SR 1722 over McLin Creek We have not identified any special concerns associated with this project.

Fish sampling data for Buffalo Creek are listed above under B-2816. Group IX Page 5 April 10, 1996 Although we do not have any special concerns regarding several of these bridge replacements, we recommend that the NCDOT incorporate the following measures into all bridge replacement projects to minimize impacts to aquatic organisms: 1) Erosion controls should be installed where soil is disturbed and maintained until project completion. 2) If concrete will be used, work must be accomplished so that wet concrete does not contact stream water. This will lessen the chance of altering water chemistry and causing a fish kill. 3) Heavy equipment should be operated from the bank rather than in stream channels in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into streams. 4) Multi-celled reinforced concrete box culverts should be designed so that all water flows through a single cell (or two if necessary) during low flow conditions. This could be accomplished by constructing a low sill on the upstream end of the other cells that will divert low flows to another cell. This will facilitate fish passage at low flows. 5) Temporary or permanent herbaceous vegetation should be planted on all bare soil within 15 days of ground disturbing activities to provide long-term erosion control. Thank you for the opportunity to review and comment during the early stages of these projects.

Franklin Vick, P.E., Manager Planning and Environmental Branch North Carolina Department of Transportation P.O. Box 25201 Raleigh, North Carolina 27611-5201 Dear Mr. Vick: ?GEI V? n G 1,196 Subject: Proposed replacement of several bridges in Alleghany, Buncombe, Catawba. Cleveland, and McDowell Counties, North Carolina A copy of your letter of March 11, 1996, to the U.S. Fish and Wildlife Service's (Service) Raleigh Field Office was forwarded to our office (we received it on March 18. 1996). Our office handles project reviews and requests of this nature for the western part of the state, including the above-mentioned counties. The following comments are provided in accordance with the provisions of the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and Section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). According to the information provided in your letter, the following bridges will be replaced: Bridge Numbers 52 and 56 on SR 1172 over the Little River (Alleghany County): Bridge Number 512 on SR 2435 over the Swannanoa River (Buncombe County): Bridge Number 82 on SR 1165 over Clark Creek (Catawba County): Bridge Number 94 on SR 1722 over McLin Creek (Catawba County); Bridge Number 35 on SR 1001 over Persimmon Creek (Cleveland County): Bridge Number 230 on SR 1908 over Buffalo Creek (Cleveland County); Bridge Number 13 on NC 198 over Buffalo Creek (Cleveland County); Bridge Number 65 on SR 1760 over Muddy Creek (McDowell County); Bridge Number 41 on SR 1147 over the Second Broad River (McDowell County); Bridge Number 317 on SR 1267 over Cove Creek: and Bridge Number 60 on SR 1764 over South Muddy Creek. The Service is particularly concerned about: (1) the potential impacts the proposed bridge replacement projects could have on federally listed species and on Federal species of concern and (2) the potential impacts to stream and wetland ecosystems within the project areas. We have reviewed our files and believe the environmental document should evaluate possible impacts to the following federally listed species and/or Federal species of concern (these include aquatic animal species 2 known from a particular stream system for one of the proposed bridge projects and plant species that may occur along the banks of streams/rivers): Alleghany County Hellbender (Crvptobranchus alleganiensis) - Federal species of concern. This species generally is found beneath large flat stones or logs in shallow clear-running streams and rivers. It is presently known from at least one location in the Little River, 7 miles east of Sparta. Kanawha minnow (Phenocobius teretulus) - Federal species of concern. This species is endemic to large clear streams within the New River drainage of North Carolina, Virginia, and West Virginia. It is presently known from at least one location in the Little River, 0.5 mile downstream of the NC 18 bridge. Buncombe County Hellbender (Crvptobranchus alleganiensis) - Federal species of concern. There is a record of this species in the Swannanoa River near Black Mountain. Spotfin chub (Hybopsis monacha) - Federally threatened. A species endemic to the Tennessee River drainage. The Little Tennessee River presently supports the only extant population in North Carolina; however, there is a historical record from the Swannanoa River in Asheville. Appalachian elktoe (Alasmidonta raveneliana) - Federally endangered. This species is endemic to the upper Tennessee River. It generally occurs in the riffle areas of large rivers that have cobble and gravel substrates. There are only a few extant populations left in the Little Tennessee River. Toe River, Cane River, and Nolichucky River systems. There is a historical record from the Swannanoa River. French Broad crayfish (Cambarus reburrus) - Federal species of concern. This species is endemic to North Carolina and is known from the headwater portions of the French Broad River and one stream in the Savannah River drainage. It was once found in the Swannanoa River near Black Mountain. French Broad heartleaf (Hexastvlis rhombiformis) - Federal species of concern. This species is generally found in association with other acidophiles, such as ericaceacous shrubs, hemlock, rhododendron, and mountain Laurel. 3 Butternut (Juglans cinerea) - Federal species of concern. This species is generally found in cove forests and rich woods, including floodplain forests. Sweet pinesap (Monotropsis odorata) - Federal species of concern. This species is generally found in dry forests and on river bluffs. Virginia spiraea (Spiraea virginiana) - Federally threatened. This species occurs within the scour zone on the banks of high-gradient streams or on braided features such as point bars, natural levees, or meander scrolls of the lower reaches of streams. It may occur within the floodplain, but it is most often found at the water's edge. There is a historical record of this species along Hominy Creek near Asheville. Catawba County Dwarf-flowered heartleaf (Hexastvlis naniflora) - Federally threatened. This species has been found along several creeks in the county, including Brushy Creek, Sandy Run, and Poundingmill Creek. Cleveland County Dwarf-flowered heartleaf (Hexastvlis naniflora) - Federally threatened. This species has been found along several tributaries to the Henry Fork River. McDowell County Bennett's Mill Cave water slater (Caecidotea carolinensis) - Federal species of concern. This species is presently known from one locality in North Carolina at a cave located on the banks of Muddy Creek east of Marion. Butternut (Juglans cinerea) - Federal species of concern. This species is generally found in cove forests and rich woods, including floodplain forests. Sweet pinesap (Monotropsis odorata) - Federal species of concern. This species is generally found in dry forests and on river bluffs. There is one known population located along the banks of South Muddy Creek in the headwaters area. Northern oconee-bells (Shortia galacifolia var. brevistyla) - Federal species of concern. This species grows in various habitats, from rocks near water falls, in sand at the edge of running water, in shady deep moist loam soils, and on dry hillsides. It favors cool, damp, shady stream banks with fertile, moderately acid, soils. 4 The presence or absence of the above-mentioned species in the project impact areas should be addressed in any environmental document prepared for these projects. Please note that the legal responsibilities of a Federal agency or their designated non-Federal representative with regard to federally listed endangered and threatened species under Section 7 of the Act are on file with the Federal Highway Administration. Also, please note that Federal species of concern are not legally protected under the Act and are not subject to any of its provisions, including Section 7, unless they are formally proposed or listed as endangered or threatened. We are including these species in our response in order to give you advance notification and to request your assistance in protecting them. Additionally, the Service believes the environmental document(s) for the proposed projects should address the following issues: (1) an evaluation of the various bridge replacement alternatives and structures (e.g., replacement at the existing location versus upstream or downstream of the existing structure), (2) any special measures proposed to minimize sedimentation during construction; and (3) any measures that will be implemented to minimize impacts to fish and wildlife habitat (e.g., protecting riparian vegetation whenever possible). We appreciate the opportunity to provide these scoping comments and request that you keep us informed of the progress of these projects. In any future correspondence concerning this project, please reference our Log Number 4-2-96-057. Sin e ely, Brian P.

C James B, Hunt, Jr., Governor Jonathan B, Howes, Secretary C A, Preston Howard, Jr., P.E„ Director April 19, 1996 MEMORANDUM To: Jim Buck From: Eric Galamb4 Subject: Water Quality Checklist for Group IX Bridge Replacement Projects The Water Quality Section of the Division of Environmental Management requests that DOT consider the following generic environmental commitments for bridge replacements: A. DEM requests that DOT strictly adhere to North Carolina regulations entitled, "Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) throughout design and construction for this project in the area that drains to streams having WS (water supply), ORW (outstanding resource water), HQW (high quality water), B (body contact), SA (shellfish water) or Tr (trout water) classifications to protect existing uses. B. DEM requests that bridges be replaced in existing location with road closure. If an on-site detour or road realignment is necessary, the approach fills should be removed to pre-construction contour and revegetated with native tree species at 320 stems per acre. C. DEM requests that weep holes not be installed in the replacement bridges in order to prevent sediment and other pollutants from entering the body of water. If this is not completely possible, weep holes should not be installed directly over water. D. Wetland impacts should be avoided (including sediment and erosion control structures/measures). If this is not possible, alternatives that minimize wetland impacts should be chosen. Mitigation for unavoidable impacts may be required. E. Borrow/waste areas should avoid wetlands. It is likely that compensatory mitigation will be required if wetlands are impacted by waste or borrow. Please be aware that 401 Certification may be denied if wetland or water impacts have not been avoided and minimized to the maximum extent practicable. cc: Monica Swihart Melba McGee bridges.sco P.O.

FLOOD PLAINS: POC - Bobby L. Willis, Special Studies and Flood Plain Services Section, at (910) 251-4728 All of the bridges, except for Alleghany and Buncombe Counties, are within the planning jurisdiction of the U.S. Army Corps of Engineers (USACE), Wilmington District. With the exception of Allegheny and Cleveland Counties, these bridges are located within counties which participate in the National Flood Insurance Program (NFIP). Allegheny County has flood hazard areas identified on Flood Hazard Boundary Maps, but has not had detailed mapping done and does not participate in the program. Cleveland County has mapping done on Flood Insurance Rate Maps (FIRMs) in anticipation of future participation in the NFIP, but does not currently participate in the program. From the various FIRMs, it appears that both approximate study and detail study streams are involved.

FLOOD PLAINS: (Continued) Enclosed, for your information on the detail study streams, is a copy of the Federal Emergency Management Agency's "Procedures for 'No Rise' Certification for Proposed Developments in Regulatory Floodways". In addition, we suggest coordination with the respective counties or communities for compliance with their flood plain ordinances and any changes, if required, to their flood insurance maps and reports. Buncombe County is within the planning jurisdiction of the USACE, Nashville District, and the Tennessee Valley Authority (TVA) with respect to any construction or development involving the flood plains. The Nashville District does not currently have projects that would be affected by this proposed project. Mr. Jamie James may be contacted at (615) 736-5948 for further information and comments from the Nashville District. Flood plain concerns are normally addressed within the TVA Section 26a permitting process. A 26a permit is required for all constnaction or development involving streams or flood plains in the Tennessee River drainage basin. Mr. Roger Milstead at (615) 632-6115 should be contacted for information on the TVA 26a permitting process. The project should be designed to meet the requirements of the National Flood Insurance Program (NFIP), administered by the Federal Emergency Management Agency (FEMA), and be in compliance with all local ordinances. The engineering point of contact for the NFIP in this FEMA region is Ms. Bel Marquez, who may be reached at (404) 853-4436. Specific questions pertaining to community flood plain regulations or developments should be referred to the local building official. Alleghany County is within the planning jurisdiction of the USACE, Huntington District. The Huntington District does not currently have projects that would be affected by the proposed project. Mr. Larry Workman may be contacted at (304) 529-5644 for further information and comments from the Huntington District. 2. WATERS AND WETLANDS: POC - Raleigh and Asheville Field Offices, Regulatory Branch (Individual POC's are listed following the comments.) All work restricted to existing high ground will not require prior Federal permit authorization. However, Department of the Army permit authorization pursuant to Section 404 of the Clean Water Act of 1977, as amended, will be required for the discharge of excavated or fill material in waters of the United States or any adjacent and/or isolated wetlands in conjunction with your proposed bridge replacements, including disposal of construction debris. May 13, 1996 Page 3 of 4 U.S. ARMY CORPS OF ENGINEERS, WILMINGTON DISTRICT, COMMENTS ON: "Request for Comments for Group IX Bridge Replace Projects" in various Western North Carolina counties 2. WATERS AND WETLANDS: (Continued) The replacement of these bridges may be eligible for nationwide permit authorization [33 CFR 330.5(a)(23)] as a Categorical Exclusion, depending upon the amount of jurisdictional wetlands to be impacted by a project and the construction techniques utilized. Please be reminded that prior to utilization of nationwide permits within any of the 25 designated mountain trout counties, you must obtain a letter with recommendation(s) from the North Carolina Wildlife Resources Commission and a letter of concurrence from the U.S. Army Corps of Engineers, Wilmington District Engineer. The mountain trout designation carries discretionary authority for the utilization of nationwide permits. In addition, any jurisdictional impacts associated with temporary access roads or detours, cofferdams, or other dewatering structures should be addressed in the Categorical Exclusion documentation in order to be authorized by Nationwide Permit No. 23 (NWP 23). If such information is not contained within the Categorical Exclusion documentation, then other DA permits may be required prior to construction activities. Although these projects may qualify for NWP 23 as a categorical exclusion, the project planning report should contain sufficient information to document that the proposed activity does not have more than a minimal individual or cumulative impact on the aquatic environment. Accordingly, we offer the following comments and recommendations to be addressed in the planning report: a. The report should contain the amount of permanent and temporary impacts to waters and wetlands as well as a description of the type of habitat that will be affected. b. Off-site detours are always preferable to on-site (temporary) detours in wetlands. If an on-site detour is the recommended action, justification should be provided. c. Project commitments should include the removal of all temporary fills from waters and wetlands. In addition, if undercutting is necessary for temporary detours, the undercut material should be stockpiled to be used to restore the site. d. The report should address impacts to recreational navigation (if any) if a bridge span will be replaced with a box culvert. e. The report should address potential impacts to anadromous fish passage if a bridge span will be replaced with culverts. May 13, 1996 Page 4 of 4 U.S. ARMY CORPS OF ENGINEERS. WILMINGTON DISTRICT.

WATERS AND WETLANDS: (Continued) At this point in time, construction plans were not available for review. When final plans are complete, including the extent and location of any work within waters of the United States and wetlands, our Regulatory Branch would appreciate the opportunity to review those plans for a project-specific determination of DA permit requirements. For additional information, please contact the following individuals: Raleigh Field Office - John Thomas at (919) 876-8441, Extension 25, for Alleghany County Asheville Field Office - Steve Lund at (704) 271-4857 for Buncombe County Steve Chapin at (704) 271-4014 for Cleveland, McDowell, and Catawba Counties ???G?NGY M^N1cF3 O 2 a R-4 Federal Emergency Management Agency Region IV 1371 Peachtree Street, NE, Suite 700 Atlanta, GA 30309 LM FOR "NO-RISE" CERTIFICA Section 60.3 (d) (3)\ of the National Flood Insurance Program (NFIP) regulations states that a community-shall "prohibit encroachments, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated-through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the occurrence of the base (100- year) flood discharge." Prior to issuing any building grading or, development permits involving activities in a regulatory floodway, the community must obtain a certification stating the proposed development will not impact the pre-project base flood elevations, floodway elevations, or floodway data widths. The certification should be obtained from the permittee and be signed and sealed by a professional engineer. The engineering or "no-rise" certification must be supported by technical data. The supporting technical data should be based upon the standard step-backwater computer model utilized to develop the 100-year floodway shown on. the community's effective Flood Insurance Rate Map or Flood Boundary and Floodway Map (FBFM) and the results tabulated in the community's Flood Insurance Study (FIS). Although communities are required to review and approve the "no- rise" submittals, they may request technical assistance and review from the FEMA regional office. However, if this alternative is chosen, the community must review the technical submittal package and verify that all supporting data, listed in the following paragraphs, are included in the package before forwarding to FEMA. -2- To support a "no-rise" certification for proposed developments encroaching into the regulatory floodway, a community will require that the following procedures be followed: Currently Effective Model 1. Furnish a written request for the step- backwater computer model for the specified stream and community, identifying the limits of the requested data. A fee will be assessed for providing the data. Send data requests to: Federal Emergency Management Agency 1371 Peachtree Street N.E., Suite 735 Atlanta, Georgia 30309 or to: FIS Information Specialist Dewberry & Davis 8401 Arlington Boulevard - Fairfax, Virginia 22031-4666 Duplicate Effective Model 2. Upon receipt of the step-backwater computer model, the engineer should run the original step-backwater model-to duplicate the data in the effective FIS. Existing Conditions Model 3. Revise the original step-backwater model to reflect site specific existing conditions by adding new cross-sections (two or more)-in the vicinity of the proposed development, without the proposed development in place. Floodway limits should be manually. set at the new cross-section locations by measuring from the effective FIRM or FBFM. The cumulative reach lengths of the stream should also remain unchanged. The results of these analyses will indicate the 100-year floodway elevations for revised existing conditions at the proposed project site. -3- Proposed Conditions Model 4. Modify the revised existing conditions model to reflect the proposed development at the new cross-sections, while retaining the currently adopted floodway widths. The overbank roughness coefficients should remain the same unless a reasonable explanation of how the proposed development will impact Manning's "n" values should be included with the supporting data. The results of this floodway run will indicate the 100-year floodway elevations for proposed conditions at the project site. These results must indicate NO impact on the 100-year flood elevations, floodway elevations, or floodway widths shown in the Duplicate`Effective Model or in the Existing Conditions Model. The original FIS model, the duplicate effective FIS model, the revised existing conditions model, and the proposed conditions model should all produce the same exact results. The "no-rise" supporting data and 'a copy of the engineering certification must be submitted to and reviewed by the appropriate community official prior to issuing a permit: The "no-rise" supporting data should include, but may not be limited to: a. Duplicate of the original PIS step-backwater model printout or floppy disk. b. ' Revised existing conditions.step-backwater model. C. Proposed conditions step-backwater model. d. FIRM and topographic map, showing floodplain and floodway, the additional cross-sections, the site location with the proposed topographic modification superimposed onto the maps, and a photocopy of the effective FIRM or FBFM showing the current regulatory floodway. e. Documentation clearly stating analysis procedures. All modifications made to the original PIS model to represent revised existing conditions, as well as . -4- those made to the revised existing conditions model to represent proposed conditions, should iwell documented and submitted with all supporting data. f. Copy of effective Floodway Data Table copied from the FIS report. g. Statement defining source of additional cross- section topographic data and supporting information. h. Cross-section plots, of the added cross sections, for revised existing and proposed conditions. i. Certified planimetric (boundary survey) information indicating the location of structures on the property. j. Copy of the microfiche, or other applicable source, from which input for original FIS HEC-2 model was taken. k. Floppy disk with all input files. 1. Printout of output files from EDIT runs for all three floodway models. The engineering "no-rise" certification and supporting technical data must stipulate NO impact on the 100-year flood elevations, floodway elevations, or floodway widths at the new cross-sections and at all existing cross-sections anywhere in the model. Therefore, the revised computer model should be run for a sufficient distance (usually one mile, depending on hydraulic slope of the stream) upstream and downstream of the development site to insure proper "no-rise" certification. Attached is a sample "no-rise" certification form that can be completed by a registered professional engineer and supplied to the community along with the supporting technical data when applying for a development permit. ?F i??V'iT?'?iVC??
