North Carolina 7, nGargliplION OF PROPOSED VI[QRK: The U. S. Army Corps of Engineers proposes to implement a natural -type stream restoration project to protect a 21 -inch sewer. line that is located adjacent to a highly eroded streambank on the Ararat River. The work would involve the installation of two rock vanes in the river and the removal and reuse of some of the point bar material (see Figure 2 of the attached EIR/EA). The rock vanes would redirect flow away from the bank and reduce velocities at the bank- In addition, material from the point bar would be used to form a small (5 -feet to 8 -feet) bench on the lower part of the stream bank. The remaining bank would be sloped back to a 1.5:1 or flatter slope, and vegetated with grasses and other native plants to provide bank protection. Stone size for the rock vanes would be in the range of 30 -inches to 64 -inches. The sand bar that has formed on the opposite bank on the inside of the bend (point bar) would be excavated to the stream invert (see Figure 2 of the EIR/EA) in order to maintain a comparable flow area and stream bottom area. Pursuant to Section 404 of the Clean Water Act, Nationwide Permit #27 (NWP #27), Stream Restoration, is applicable to the proposed work. A Section 401 (P -L. 95-217 and P.L. 92-500) water quality certificate, #3399, has been issued for NWP #27. Concurrence from the NC DWQ is required and is requested via this application. g, pr 1gp1nr!bF OF PROPOs>Ea WORK: Bank erosion in the project area threatens to undermine an existing 21" sewer line that runs adjacent and parallel to the Ararat River at Riverside Park in Mount Airy, North Carolina.

ENVIRONMENTAL ASSESSMENT CONTINUING AUTHORITIES PROGRAM SECTION 14 EMERGENCY STREAMBANK EROSION CONTROL PROJECT SEPTEMBER 2004 1.0 STUDY INTRODUCTION 1.01 Study Authority. Section 14 of the 1946 Flood Control Act provides authority for the U.S. Army Corps of Engineers (Corps) to develop and construct emergency streambank and shoreline protection projects to protect endangered highways, highway bridge approaches, public works facilities such as water and sewer lines, churches, public and private non-profit schools and hospitals, and other non-profit public facilities. Each project is limited to a federal cost of $1,000,000 for planning, design and construction. 1.02 Study Area. The study area is in Mount Airy, North Carolina, which is about 35 miles northwest of Winston-Salem, North Carolina. Mount Airy is the only significant urban area in Surry County. A location map is included as Figure 1. 1.02.1 Ararat River at Riverside Park. The Ararat River, a tributary of the Yadkin River, extends in a north -south direction across the entire eastern portion of Surry County. The proposed project area is along the outside bank of a bend in the Ararat River at Riverside Park. This location is just downstream from a federal flood damage reduction project, completed in the 1980's, which was described in the Detailed Project Report and Environmental Impact Statement on Flood Damaae Reduction. Ararat River. Mount Airy, Surry County, North Carolina. 1.02.2 Fairway Lane. A small, unnamed stream, which is a tributary of Lovills Creek, runs parallel to Fairway Lane — a residential city street on the north side of town — for about 600 feet. At the lower end of this reach, a larger tributary passes under the road through a 42" culvert and joins the stream at almost a 90 -degree angle. The drainage area is 31 acres, above this confluence and 141 acres below. 1.03 Purpose and Need for Action. 1.03.1 Ararat River at Riverside Park. In recent years, the bank has become steeper due to erosion and is threatening to undermine the existing 21" sewer line. Without action, the bank will continue to erode and the sewer will be washed out, resulting in loss of service and a sewage release, estimated to be in the hundreds of thousands of gallons, into the stream. Due to the likely large extent of a spill, it is expected that the North Carolina Division of Water Quality would levy a severe fine on 1 the city. Note that the quantities and options analyzed for this project are based on 1990 topographic maps provided by the city that do not reflect the recent erosion. New surveys will be acquired for preparation of final plans and scope of work for construction contract advertisement. 1.03.2 Fairway Lane. In recent years, the stream has deepened and the bank adjacent to the roadway has become near vertical due to erosion. The situation appears to be worse at the 90 -degree confluence, which creates a turbulent condition. The road is frequently overtopped due to an undersized culvert. In some areas the top of bank has eroded to within a foot of the edge of pavement and threatens to undermine the pavement and a parallel sanitary sewer. Attempts to slow this process by dumping concrete rubble along parts of the stream have not been effective. Note that. -the quantities and options analyzed for this project are based on topographic maps provided by the city that do not reflect the recent erosion. New surveys will be required to complete a construction document. 1.04 Integrated National Environmental Policy Act (NEPA and Feasibility Document.. The Council- on Environmental --Quality -Guidelines encourages -the integration of .., NEPA reports with other documents, such as planning reports, in order to reduce paper work and to present information in a concise manner. The Corps strongly supports this approach. Therefore, this document integrates the NEPA Environmental Assessment with the Feasibility (Planning and Design Analysis) Documentation 2.0 PLAN FORMULATION AND EVALUATION OF ALTERNATIVES Federal planning guidance and NEPA require that alternative plans be formulated in a systematic manner to insure that all reasonable alternatives are evaluated. A number of alternatives are usually identified early in the planning process, and their number is reduced by screening, evaluation, and comparison in an iterative sequence to lead to identification of the recommended plan. Plan formulation and evaluation of alternatives are discussed below. 2.01 Formulation and Evaluation Criteria Alternative plans are evaluated through application of numerous, rigorous criteria. These include basic, general criteria as well as four categories of technical criteria, including (1) engineering, (2). economic, (3) environmental, and (4) institutional items. These include the following: o Must comply with applicable Federal laws and regulations o Must comply with applicable State and local laws and regulations, to the maximum extent practicable o Must comply with U.S. Army Corps of Engineers regulations. 01 o Must represent sound, acceptable, and safe engineering solution o Benefits of a plan must exceed economic costs o May not result in unacceptable adverse impacts on the environment o Must satisfactorily address the identified needs and concerns of the public o Must be implementable with respect to financial and institutional capabilities o Must be implementable with regard to public support 2.02 Identification and Evaluation of Alternative Plans 2.02.1 No Action Alternative. The no action alternative could result in significant adverse social, economic and environmental impacts to the local communities and the Town -of Mount Airy. 2.02.1.1 -Ararat River. Continued erosion of the Ararat River bank would cause damage to the sewer line. In its present condition, even a minor flood event could result'in a line break and significant discharge of raw sewage into the Ararat River. If the sewer line were to wash out or break, the resulting sewer spill would be in the hundreds of thousands of gallons. The resulting environmental damage could be catastrophic, extending many miles downstream, and could result in fines of $100,000 or more. In addition;"nurnerous-"residents "and businesses would be without ` -sewer ser=vice'untii repairs could be made. 2.02.1.2 Fairway Lane. Continued bank erosion. along the stream paralleling the existing street would ultimately result in failure of the street and a potential break in the sewer and water lines, which could have significant environmental and economic consequences. The existing street provides the only access for 38 residences in the development. 2.02.2 Alternate Plans Investigated. Alternate plans for both the. Ararat River site and Fairway Lane were considered and are discussed below and are summarized in Table 1. 2.02.2.1 Ararat River. Initially grading of the bank to a more stable slope and protecting it with rip -rap was considered; however, to avoid impacts to the sewer this would have required extending the toe of the bank into the stream a significant distance. Although the Ararat River in the project vicinity is somewhat degraded, it is designated by the State of North Carolina as a trout stream. The placement of riprap in the stream could further degrade the value of the stream as trout habitat and is therefore considered environmentally unacceptable where an alternative plan could result in the enhancement of the stream as habitat for trout and other aquatic species. Relocation of the sewer away from- the bank was also considered, but. would require clearing of existing mature vegetation and significant excavation into a high bank that parallels the sewer line. Due to potential environmental impacts and project costs, this alternative was not deemed the preferable alternative. 3 Other alternatives that were considered included stabilizing the bank with gabions, a segmental block wall, or a sheet pile wall. These alternatives were not considered feasible, due to cost. In addition to being the highest cost alternative, the sheet pile wall would likely encounter construction difficulties due to bedrock. A final alternative that was considered involved protection of the bank with rock vanes to redirect the flow away from the bank and thus reduce erosion. Also included would be removal of a sand bar in the river to maintain a comparable flow area and provide material to partially restore the eroded bank. This plan would also provide environmental benefits and is the recommended plan described in paragraph 3.01.1. 2.02.2.2 Fairway Lane. Relocation of the street away from the stream was considered. This would require road relocation, a sewer line and a water line relocation, and permanent right of way. Due to impacts to adjacent landowners and project costs, this alternative was eliminated from further consideration. Two other alternatives considered at Fairway Lane included biotechnical erosion control and placement of riprap. However, due to the steep bank and the close proximity of the stream to the road, space is too limited to accommodate either of these ;.--alterrnatives A final alternative considered included piping of a portion of the stream adjacent to the road, realigning the stream under the road, increasing culvert capacity, and grading and stabilization of the bank. This is the recommended plan and is described in more detail in paragraph 3.02.1.1. 0 TABLE 1 ALTERNATIVES CONSIDERED STREAM ALTERNATIVE FIRST COST $1000's REMARKS Ararat River Riprap sloe 137 Not environmentally acceptable Ararat River Gabions 217 Higher costs Ararat River Segmental Block Wall 308 Higher costs Ararat River I Sheet pile Wall 389 Construction difficulties and high costs Ararat River Relocate sewer line 163 Potential environmental impacts and higher costs Ararat River Install rock vanes 115 Redirects flow away from channel bank, cost effective alternative Fairway Lane Relocate street, water and sewer line 300 Impacts to adjacent landowners; higher costs FairwayLane .

Protection of the bank by installing rock vanes in the river as indicated on the attached drawing (Figure 2.) is proposed. The vanes would redirect flow away from the bank and reduce velocities at the bank. In addition, a small (5' to 9') width bench would be formed on the lower part of the streambank. The remaining bank would be sloped back to a 1.5:1 or flatter slope, and vegetated with grasses and other native plants to provide bank protection. Stone size for the vanes would be in the range of 30" to 54". The sand bar that has formed on the opposite bank on the inside of the bend (point bar) would be excavated to the stream invert (bottom of the stream channel) (see Figure 3) in order to maintain a 5 comparable flow area and stream bottom area. The estimated cost of this option is shown in Table 2, and construction details are included as Appendix A.

Construction of this concept will require in -stream excavation to remove the . sandbar and construct the vanes. It is planned that the material from the sandbar would be placed along the bank to partially restore the eroded bank prior to constructing the vanes. (A nearby disposal area is available in the event more material is removed than is needed to partially restore the bank.) This would require some form of sandbag diversion, or turbidity curtain to reduce turbidity. Since the area affected is less than one acre, an erosion control permit will not be required. Maintenance of the vanes is not expected to be significant. Mowing of the grassed area is already accomplished, since it is part of a city park. - 3.01.3 Real Estate Considerations. Since the work area is contained in a city park, no real. estate acquisition should be required, and only minor administrative costs are shown for lands, easements, rights-of-way, relocations, and disposal areas (LERRD's). 3.02 Economics of the Recommended Plan The without project condition is that the sewer line along the Ararat River would 'be 'highly"subject 'io"washout with''tlie ensuing 'environmental `darnage and -- " disruption of service to a significant population within the city. The City of Mount Airy would then relocate the line. Without considering the environmental or loss of use costs, the cost of emergency relocation of the sewer line is estimated by the Wilmington District to be $163,000 with an average annual cost of $12,300 under the without project conditions. The with -project conditions will result in constructing the recommended plan, which has an initial cost of $115,000 and an average annual cost of $8,678. This will eliminate the need for emergency relocation of the sewer line, for an average annual savings (benefits) of $12,300. The average annual benefits of $12,300 verses the average annual costs of $8,678 results in a benefit to cost ratio of 1.4 for the recommended plan.. 3.02.1 Fairway Lane 3.02.1.1 Plan Description, Components, and Costs. Piping of part of the stream adjacent to Fairway Lane, realigning the stream under the road to improve alignment and reduce channel scour at the confluence, increasing the capacity of the culvert under the road, and grading and stabilization of the banks were evaluated. The plan includes piping about 250 feet of the stream (station 5+20 to 7+60 on attached plan, Figure 4). The plan also includes replacing the existing 42" culvert under the road with two 42" pipes skewed to the road. Riprap will be used at pipe outlets to reduce scour as well as headwalls for the 42" pipes. The channel downstream of the confluence will be graded to provide a 1.5:1 or flatter side slope and the area over the new pipe will be graded to provide a swale for flows exceeding the capacity of the culverts. 7 The estimated cost of this option is shown in Table 3, and construction details are included as Appendix A.

TOTAL EXCLUDING PLANNING $175,000 $41,000 $216,000 PORTION OF PDA COSTS(SUNK COSTS) FOR BENEFIT/COST ANALYSIS 3.02.1.2 Construction and Maintenance Considerations. Because the street is the only access to the residential areas beyond, the Contractor will be required to keep one lane of traffic open during construction. This will require construction of a temporary, detour or jacking of the new pipe under the street. About 50' of 12" water line will have to be relocated vertically to allow installation of the 42" culverts. General maintenance of the area would include mowing and occasional repair of erosion ruts and repair of turf. The 42" culverts would have the capacity to carry an estimated 17 -year flood event before overtopping. Considering a 25 -year project life, some overtopping would be expected with the project in place. An estimated annual maintenance cost of $500 has been �3 included in the total average annual costs to cover this expense, which would be the responsibility of the City. 3.02.1.3 Real Estate Considerations. This concept will require no new permanent right-of-way, but could require a temporary construction easement for the detour and Contractor work area. 3.02.1.4 Economics of the Recommended Plan The without project condition is that Fairway Lane would be subject to wash out as well as the possibility of a sewer line and water line break with the ensuing environmental damage and disruption of service to a significant population within the city. (The sewer line serves the local area, but the water line is a main line serving a much larger population). The City of Mount Airy would then likely relocate the road and water and sewer lines. Without considering the environmental or loss of use costs, the cost of emergency relocation of the sewer line is estimated by the Wilmington District to be $300,000 with an average annual cost of $22,600 under the without project conditions. 'The with -project c6iiditi6hs will `result in constructing the recommended plan, which has an initial cost of $216,000 and an average annual cost of $16,800, including $500 in maintenance costs. This will eliminate the need for emergency relocation of the sewer line, for an average annual savings (benefits) of $22,600. The average annual benefits of $22,600 versus the average annual costs of $16,800 results in a benefit to cost ratio of 1.3 for the recommended plan. 4.0 ENVIRONMENTAL CONSIDERATIONS 4.01 Sediments. Streambed material at the Ararat River site is a tan, fine to medium sand with a large amount of gravel (SP). Bank material is light brown sandy silt with gravel and some mica (ML). Material at the Fairway Lane site is sandy silt with some gravel. Construction impacts to sediments would result from removal of vegetation along the eroded bank of the Ararat River and from removal of a portion of the point bar material in the River. At the Fairway Lane site, a minimal amount of grassy vegetation along the road right-of-way would be disturbed; however, impacts would be temporary. Removal of vegetation at both project locations may result in temporary, short-term increases in erosion and sedimentation, however, impacts would be minimized by implementing appropriate sediment and erosion control practices and all impacts would be temporary. Following construction, all disturbed areas would be revegetated with native plants. 6 Photographs of the Ararat River site are shown as Figures 5 and 6, and a photograph of the Fairway Lane site is shown as Figure 7. 4.02 Water Quality and Wetlands. The North Carolina water quality classification assigned to the Ararat River from the Town of Mount Airy proposed water supply intake to a point 0.1 mile upstream of Surry County SR 2080 is "C" (15A NCAC 2B .0309). All unnamed tributaries, such as the one at Fairway Lane are also classified as Class "C." Class "C" waters are freshwaters protected for secondary recreation, fishing, aquatic life, including propagation and survival;- and wildlife. The projects are expected to have a favorable long-term effect on water quality, since bank erosion results in increased sediment and debris in the waterways, thereby increasing turbidity and restricting flow. The projects are expected to reduce long-term turbidity below present conditions; however, it is expected that during construction a short-term temporary increase in turbidity may occur. Appropriate sediment and erosion control practices, which equal or exceed those outlined in the most recent version of the "North Carolina Erosion and Sediment Control Planning and Design Manual" shall be designed, installed and maintained properly to assure compliance with the appropriate turbidity standards. Nursuantto Section 404 of -the Clean Water -Act, Nationwide Permit #27 (NWP #27), Stream Restoration, is applicable to the proposed work at the Ararat River. A Section 401 (P.L. 95-217 and P.L. 92-500) water quality certificate, #3399, has been issued for NWP #27. Concurrence from the N.C. Department of Environment, Health, and Natural Resources, Division of Environmental Management, Water Quality Planning, Raleigh, N.C., is required and has been requested. Pursuant to Section 404 of the Clean Water Act, Nationwide Permit #3 (NWP #3), maintenance, is applicable to the proposed work at Fairway Lane. A Section 401 (P.L. 95-217 and P.L. 92-500) water quality certificate (WQC), #3376, has been issued for NWP #3. All conditions of NWP #3 and WQC #3376 will be met, therefore, concurrence from the N.C. Department of Environment, Health, and Natural Resources, Division of Environmental Management, Water Quality Planning, Raleigh, N.C., is not required. A public notice will be sent.out for a 30 -day review concurrent with the public review for the EA. No adverse impacts to groundwater resources are expected to occur as a result of the proposed activity. 4.03 Floodplains. There is no viable plan at the Ararat River site, other than construction within the flood plain. The City of Mount Airy is a participant in the National Flood Insurance Program. Ararat River is a detailed study stream with 100 -year flood elevations determined and a floodway defined. Since the proposed project for the river includes placement of construction material within the floodway, it is required that an engineering analysis be accomplished to show that there will 10 not be any increase in the 100 -year flood elevations due to the implementation of the project. This analysis will be accomplished prior to construction. The site at Fairway Lane does not have an identified flood plain or floodway designated on the pertinent Federal Emergency Management Agency Flood Insurance Rate Map. Therefore, a no -rise analysis would not be required for this site. 4.04 Hazardous and Toxic Waste. A field inspection of the project area was made by personnel from the Environmental Resources Section, Planning and Environmental Branch, U.S. Army Corps of Engineers, Wilmington District, on May 26, 2004. This site visit focused on the areas that would be impacted by the proposed project. Based on this site visit, an investigation of aerial photos, and a search of known HTRW databases, no evidence of hazardous and toxic wastes was found. Therefore, it is not expected that any hazardous and toxic waste sites. would be encountered during construction or maintenance of the subject project. 4.05 Cultural Resources 4.05.1 Ararat River. The proposed project alternatives are federal undertakings as defined in Section 106 of the National Historic Preservation Act as codified at 36CFR 800, Protection of Historic Properties. In general, the Mount Airy vicinity represents a typically disturbed urban environment with only a low to moderate potential for yielding significant historic properties. Nevertheless, numerous prehistoric and historic sites are known to occur and can be expected near undisturbed watercourses. The Ararat River portion of the project was addressed in the U.S. Army Corps of Engineers (USACE) Detailed Project Report (DPR) for the Ararat River Flood Damage Reduction study (USAGE 1983). The DPR contained the text of the archaeological survey for the project area (Baker 1981). The archaeological survey report recorded no sites in the project area and recommended no further survey. The North Carolina State Historic Preservation Officer concurred with that recommendation (USAGE 1983:H-40). No further cultural resources investigations are warranted for the Ararat River portion of the project. 4.05.2 Fairway Lane. The Fairway Lane project area is limited to the intersection of an unnamed intermittent stream (tributary to Lovills Creek) and Fairway Lane: The eroded streambed has the appearance of a gully, and adjacent areas are likely to have been disturbed by initial road construction, construction and operation of a pumping station, construction and operation of a golf course, and excavation for water and sewer lines. Given the limited extent of the project and the extent of past disturbance, significant cultural resources are not likely to be encountered and no further cultural resources investigations are warranted. 11 4.06 Air Quality. The only potential impact to air quality as a result of the proposed action would be increases in dust emission; however, this impact would be temporary, and occur only while construction is ongoing. No other adverse impacts to air quality are expected as a result of the proposed project. 4.07 Noise. During construction, heavy equipment would produce noticeable increased noise levels in the immediate vicinity of project activity; however, all work must comply with Occupational Safety and Health Administration (OSHA), standards for the construction industry. All noise increases resulting from project construction would be temporary and of relatively short duration. No long-term adverse noise impacts are anticipated as a result of the proposed project. 4.08 Benthic Resources 4.08.1 Ararat River. The placement of the rock vanes and the associated tapered fill upstream of the vanes would cover approximately 2,178 square feet (0.05 acre) of stream bottom habitat; however, the removal of material from the point bar would-resIdlf iii an increase in'the"area"of'stream bottom iabitat`V- approximately 8,712 square feet (0.2 acre), thus resulting in an overall increase of 6,534 square feet (0.15 acre) of stream bottom habitat. Benthic organisms in the Ararat River would be expected to inhabit the stream bottom habitat that would result from project construction. The hard substrate that would be provided by the rock vanes should become inhabited by organisms adapted to hard substrate. 4.08.2 Fairway Lane Past attempts to stabilize the stream by using various types of broken concrete and other debris have covered much of the streambank and the very narrow (approximately 2 -feet wide) stream bottom. The proposed action would result in the removal of much of this debris and would include the installation of a 36" pipe in portions of the existing stream channel (see plans). Placement of the pipe would result in the covering of approximately 500 square feet (0.011 acre) of stream bottom habitat. However, placement of the pipe would result in a reduction of stream bottom erosion and bank erosion thereby decreasing turbidity, which should benefit downstream benthic habitat. 4.09 Fisheries. 4.09.1 . Ararat River. The Ararat River is designated as Public Mountain Trout Waters by the North Carolina Wildlife Resources Commission (NCWRC). The Ararat River is further designated as Hatchery Supported Trout Waters, which means it must be stocked periodically with trout to sustain fishing. Catchable sized brook, rainbow, and brown trout are stocked by the NCWRC during March, April and May, as follows: 12 Type March April May Brook trout (Salvelinus fontinalis) 40 40 30 Rainbow trout (Oncorhychus mykiss) 40 40 30 Brown trout (Salmo trutta) 20 20 15 Besides brook, rainbow and brown trout, other species that have been collected in the project vicinity include redbreast sunfish (Lepomis auritus), largemouth bass (Micropterus salmoides), and black crappie (Pomoxis nigromaculatus) (USACE 1982). The most common species found in the Ararat River today, besides trout, are common bream (Abramis brama), redbreast sunfish (Lepomis auritus), and a small number of smallmouth bass (Micropterus dolomieui) (Ken Hodges, NCWRC, Personal Communication, July 26, 2004). Although the Ararat River is designated as a trout water, conditions are so degraded that trout do not reproduce in the Mount Airy area, and are stocked only for recreational purposes, i.e. managed as a "Put and Take" stream (Personal Communication, Ken Hodges, NCWRC on July 26, 2004). The project would be constructed in the fall or winter to avoid impacts to the recreational fishing season of March through June. The proposed installation of rock vanes and modification of the point bar to mimic a more natural stream channel should benefit fishery habitat by creating a pool around and downstream of the end of the rock vanes, providing channel diversity, providing cover, capturing fine sediment and providing a more stable area for riparian vegetation to grow. The proposed riparian vegetation would provide shading, protective cover, and an important food source for aquatic species. As stated previously, the project is expected to reduce long-term turbidity below present conditions; however, it is expected that during construction a short- term temporary increase in turbidity may occur. Appropriate sediment and erosion control shall be designed, installed and maintained properly to assure compliance with the appropriate turbidity standards. 4.09.2 Fairway Lane The unnamed streams that are at the Fairway Lane site are very narrow, shallow, and highly disturbed and therefore, probably provide very little, if any, fishery habitat. The proposed project should have negligible effect on the fishery habitat at the site; however, downstream habitat would be expected to improve due to decreases in long-term sedimentation and erosion. During construction, a short-term temporary increase in turbidity may occur; however, impacts would be temporary and of short duration. 13 4.10 Terrestrial Resources 4.10.1 Ararat River Erosion along the Ararat River bank has destroyed much of the streambank vegetation, leaving an eroded, steep dirt slope (Figures 5 and 6). Vegetation at the top of the river bank consists of grasses that are frequently mowed as part of Riverside Park maintenance. A 5' to 9' bench would be constructed near the bottom of the streambank and the remaining bank would be sloped back to a 1.5:1 or flatter slope, which would result in approximately 0.18 acres of ground clearing of 0.18 acre of grasses on the top of the bank. No other impacts to terrestrial resources are expected, and all disturbed areas, including the bench, would be vegetated with grasses and other native plants. The streamside herbaceous vegetation specifications and streamside woody vegetation establishment that would be used for this project were provided by the National Resources Conservation Service and are included as Attachment 2. 4.10.2 Fairway Lane Vegetation at Fairway ' Lane consists of mowed ' grasses on the -top _ of" the bank, adjacent to the road (Figure 7). The bank opposite the road contains some herbaceous plants and grasses, but the streambank is mostly denuded of vegetation by erosion and the concrete debris that has been used in the past in attempts to slow erosion. The proposed project construction would disturb approximately 0.35 acre in the grassed right-of-way and along the streambank. However, all disturbed areas would be planted with native vegetation immediately following construction, so impacts would be minor and temporary. 4.11 Endangered and Threatened Species The proposed work has been reviewed for compliance with the Endangered Species Act of 1973, as amended. The following species may occur in the project area and must be considered: SPECIES Vertebrates Bog turtle Vascular Plants Schweinitz's sunflower Small -whorled pogonia SCIENTIFIC NAME Clemmys muhlenbergii Helianthus schweinitzii Isotria medeoloides STATUS T(Similarity of Appearance) Endangered Threatened The bog turtle is generally found in open, early successional types of habitats such as wet meadows or open boggy areas generally dominated by sedges (Carex spp.) or sphagnum moss. A site visit conducted by the U.S. Army Corps of Engineers on May 26, 2004 revealed that the project sites offer very poor habitat for the species. As no conclusive evidence of bog turtles was found, the 14 species is believed to be absent from the project area; therefore, the proposed action would not affect this species. Schweinitz's sunflower occurs in clearings and edges of upland woods on moist to dryish clays, clay-loams, or sandy clay-loams that often have high gravel content. It usually grows in open habitats not typical of the current general landscape in the piedmont of the Carolinas (http://nc-es.fws..qov/plant/schwsun.hsml). Habitat for Schweinitz's sunflower is absent from the project areas; therefore, the projects would not impact this species.. Small -whorled pogonia is generally known from open, dry, deciduous woods with acid soil. It occurs in habitat where there is relatively high shrub coverage or high sapling density. Since this habitat is absent from the project sites, the project would not impact this species. 4.12 Wildlife. Wildlife expected to occur in the project areas are various waterfowl, songbirds, migratory birds, raptors and small mammals. The planting of native vegetation would provide a more diverse vegetative cover, which would enhance habitat for wildlife by providing cover and food near a water source. Wildlife using the project areas may be minimally affected by noise and other activities associated with construction work; however, impacts would be temporary and species that avoid the areas during construction- would be expected to return to the project areas following construction. Some wildlife would likely become habituated to the noise and activity and may remain in the area. During the site visit on May 26, 2004, bank swallows were seen using the bank at the Ararat River. The proposed project would remove a vertical bank approximately 250 linear feet in length, which would make it undesirable for bank swallows. However, bank swallows are opportunistic species and will search for other suitable nesting sites, which are available just downstream of the project area. Project construction is planned for the winter when bank swallows are in the tropics; therefore, construction would not impact bank swallows during nesting season. 4.13 Aesthetic and Recreational Resources 4.13.1 Ararat River. The Ararat River project area is adjacent to Riverside Park, which is a public park. Visual quality at the project site has been degraded by the eroded streambanks and loss of vegetation. However, plans to lessen the steep bank slope, install a bench on the streambank and plant vegetation should greatly improve aesthetics of the area. As stated previously, trout are stocked in the river at Riverside Park specifically for recreational fishing. The proposed project should improve trout 15 habitat, which has the potential to improve fishing conditions and the bank protection would provide a more stable bank for fishermen. 4.13.2 Fairway Lane Aesthetics at Fairway Lane have been negatively impacted by past attempts to stabilize the area using various shapes and sizes of concrete and riprap and recent actions taken to mark the dangerous stream crossing using a metal barrier and orange cones. The proposed project at Fairway Lane would remove the debris that has been placed in the stream in the project reach, would revegetate disturbed areas and would alleviate the need for protective barriers and safety markers, thereby, improving aesthetics. Since Fairway Lane is a fairly narrow residential street, recreational , activities in the road right-of-way are probably -limited to walking and jogging by nearby residents. The proposed work at the stream crossing should improve the stability of the road shoulder and increase the width of the shoulder at the stream crossing, thereby, improving safety and aesthetics for those pursuing recreational activities. No negative impacts to aesthetics or recreational activities would be expected:M .... + 4.14 Cumulative Effects. The Council on Environmental Quality (CEQ) defines cumulative impact as: the impact on the environment which results from the incremental impact of the action when added to other past, present and reasonably foreseeable actions regardless of what agency (Federal or non - Federal) or person undertakes such other actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time (40 CFR 1508.7). The geographic boundaries that were evaluated for this cumulative effects analysis include the City of Mount Airy and adjacent outlying areas. Past actions that have affected the Ararat River are predominantly associated with the urbanization of the City of Mount Airy. Current census data (2000) indicates that the population of Mount Airy is approximately 8,484. According to 1997 data there were 55 manufacturing facilities, including numerous textile and apparel knitting mills, in Mount Airy, as well as many other wholesale and retail businesses. This urbanization has impacted the landscape in many ways, but in general, the large-scale land clearing has resulted in increases in pollution, sedimentation and erosion in nearby streams and rivers. One project that directly affected the Ararat River was a flood damage reduction project constructed by the U.S. Army Corps of Engineers in the early 1980's. The project consists of 5,100 feet of dike to protect industrial sites in the flood plain and channel improvements that were 6,700 feet in length that were constructed contiguous to and downstream of the diked area. 71 The purpose of the proposed projects is to protect existing threatened infrastructure at the Ararat River and at Fairway Lane. Since project impacts are limited to a small area and the project is expected to have a beneficial effect on the environment, the action, when added to other past, present, and reasonably foreseeable future actions would be minor. 4.15 Executive Orders Executive Order 11990 -Protection of Wetlands Requires federal agencies to avoid undertaking or providing assistance for new construction located in wetlands unless there is no practicable alternative, and all practicable measures to minimize harm to wetlands have been implemented. Also precludes GSA from leasing space in wetland areas unless there are no practicable alternatives. There are no potential alternatives which would avoid impacts to wetlands; however, all work is covered by existing Nationwide Permits (NWP's) and impacts to wetlands will be minimized by strictly meeting the conditions of those NWP's. Executive Order"11983 -`Flood Plain Management Requires federal agencies to avoid the adverse impacts associated with the occupancy and modification of floodplains and to avoid floodplain development whenever possible. Additionally, it requires federal agencies to strive to 1) reduce the risk of flood loss, 2) minimize the impact of floods on human health, safety, and welfare, and 3) preserve the natural beneficial value of floodplains. There is no viable plan other than construction within the flood plain. An engineering analysis will be accomplished to ensure that there will not be any increase in the 100 -year flood elevations due to the implementation of the.projects. This analysis will be accomplished prior to construction. Additionally, the projects will minimize the impact of floods on human health by protecting .a sewer line that is being undermined. by streambank erosion at the Ararat River site and by protecting a sewer line, water line, and road at the Fairway Lane site. Executive Order 13045 - Protection of Children From Environmental Health Risks and Safety Risks This order addresses the disproportionate impact environmental hazards have on children due to their small size and developing bodies and the greater safety requirements necessitated by children's general behavior patterns. The order requires Federal Agencies to make children's health and its protection a high priority and ensure that their "policies, programs, activities, and standards address disproportionate risks to children..." The order requires agencies to further evaluate the health and safety risk to children posed by each regulation. The projects would not adversely -affect the health and safety of children and has the potential to improve health and safety of children by improving water quality 17 in the Ararat River and by providing a safer, more stable streambank for Riverside Park visitors. At the Fairway Lane site, water quality is also expected to be improved and the road shoulder stabilized, thus providing a safer, healthier environment for children. Executive Order 12898 - Federal Actions to Address Environmental Justice in Minority Populations and Low -Income Populations This Order focuses Federal attention on the environmental and human health conditions in minority and low-income communities with the goal of achieving environmental justice. In addition, this Order requires federal agencies to provide minority and low-income communities access to public information on, and an opportunity for public participation in, matters relating to human health or the environment. The proposed project would not adversely impact minority populations or low-income populations and this document will be circulated to the public for 30 -day review, thereby providing the opportunity for public participation. 4.16 Finding. The Proposed Action is not expected to significantly affect the quality of the human environment; therefore, an Environmental Impact Statement would' not be prepared. If this opinion is upheld following circulation of this EA, a FONSI will be signed and circulated. 5.0 COORDINATION AND PUBLIC INVOLVEMENT 5.01 Scoping. Informal scoping was conducted by phone, emails and site visits with the City of Mount Airy, the Natural Resources Conservation Service and the North Carolina Wildlife Resources Commission. All input received on the proposed project was considered and addressed in this report. 5.02 Fish & Wildlife Coordination. Existing project conditions, potential project impacts, construction methods and time of year for construction were coordinated with the North Carolina Wildlife Resources Commission. The' endangered and threatened species list that is included in this document was obtained from the U. S.

Project Implementation Costs ($1,OOOs): Federal Funding Needs Phase Totals Non -Fed Fed Thru FY04 FY05 FY06 BTC Planning, Design, and Analysis 157 0 157 26 131 0 0 Construction 223 133 90 48 42 0 Totals 380 133 247 26 179 42 0 Note: The Planning and Design Analysis phase is initially Federally financed, and the non -Federal share is distributed as part of the non -Federal share of project costs during implementation. Funding above does not include the first $40,000 of the PDA phase, which is full Federal funding, and is not included in the implementation costs. The non -Federal sponsor must provide all LERRD 20 necessary for the project. The required cost -share ratio is 35 percent non - Federal and 65 percent Federal, of which a minimum of 5 percent of the non - Federal share must be cash. All operation and maintenance costs are a non - Federal responsibility. b. Non -Federal Requirements: LERRD $2,000 Cash $129,000 PCT $2,000 Annual OMRRR $500 c. Federal Allocations to Date: $ 68,000 7.0 CONCLUSIONS: Based on the findings in this report, it is considered in the Federal interest to implement the recommended plan for emergency streambank erosion control. The plan will meet the objective of protecting both the sewer line at Ararat _River -and theroad, water line, and sewer line at Fairway Lane at a' ___ benefit -to -cost ratio of 1.4 for the Ararat River site, 1.3 at the Fairway Lane site, and 1.3 overall. Environmental portion of conclusion - Project construction may result in increases in noise, turbidity and sedimentation, however, impacts would be temporary and of short duration. The project is expected to have long-term beneficial effects on turbidity, sedimentation and erosion, thereby improving terrestrial and aquatic habitat at the project sites. 8.0 POINT OF CONTACT Bobby L.

Care and Handling Planting stock should be stored in a cool moist environment or heeled in. Roots of bareroot stock shall be kept moist during planting operations. Container or potted stock shall be kept moist at all times. The root balls of transplanted stock must be kept moist. Site Preparation Desirable trees and shrubs on the construction site should be dug and stored. On recently graded sites use temporary seedings, anchored mulch or erosion control fabrics to provide surface protection until woody vegetation becomes established. Sod may be killed by non-selective herbicides the year previous to planting stock (follow all federal, state and local regulations in the use of herbicides). When hand planting; scalp an area at least 3 feet in diameter and 2-4 inches deep. Place plant in the center of the scalped area. On sites where equipment cannot be operated safely and there are concerns about potential erosion use a non-selective herbicide to kill vegetation in a 36 -inch wide circle or 36 inch wide strip and -plant in the center of the killed vegetation. If the site is a row crop site, reasonably free of weeds, plant stock in the stubble without prior preparation. Sites with undesirable brush will need initial treatments to facilitate planting and follow-up treatments to prevent reencroachment. ,Planting. .. 31- . - .. ._ , Transplants should be.replanted.to.the same -depth they were -originally. growing... Plant rooted.stock in a.vertical ... _ . position with the root collar approximately ''h inch below the soil surface. The planting trench or hole must be deep enough and wide enough to permit roots to spread out and down without J -rooting. Insert dormant cuttings to the depth required to reach adequate soil moisture, leaving 2 to 3 buds above ground. After planting pack soil around each plant firmly to remove air pockets.

Seedbed Preparation On sites where equipment can be operated safely the seedbed shall be adequately loosened and smoothed. Disking or cultipacking or both may be necessary. On sites where equipment cannot operate safely, the seedbed shall be prepared by hand scarifying to provide a roughened surface so that seed will stay in place. If seeding is done immediately following construction, seedbed preparation may not be required except on compacted, polished or freshly cut areas. Fertilizing Evenly distribute lime and fertilizer over the area to be seeded. Uniformly mix lime and fertilizer into the top 3 inches of the soil. Where surface materials are predominately gravel and/or cobble, no incorporation is required. Apply lime and fertilizer according to soil test results or at the following rates. Per 1000 sq. ft. Per Acre Lime 50-100 lbs. 1-2 tons 10-10-10 Fertilizer 9-12 lbs. 4-500 lbs. Sod Mats - Strip and -stockpile mats of existing desirable herbaceous vegetation.. Insure that several inches of -sod remains attachedto the vegetation. The root systems must remain moist while the- vegetation is stockpiled. Place the mats on the lower bank - - slopes and anchor in place. Seeding Temporary Seeding - Use where needed for erosion and pollution control, when permanent vegetation cannot be established due to planting season and where temporary ground cover is needed to allow native or woody vegetation to become established. Fall, Winter, SpringSeeding Per 1000 sq. ft. Per Acre Oats 2 lbs. 3 bu. Wheat 2 lbs. 3 bu. Summer Seeding Sudangrass l lb. 35-45 lbs. Browntop Millet 1 lb. 30-40 lbs. Permanent Seeding — Use in combination with woody plantings on the upslope side of the riparian planting. Spring planting time is ideal for native perennial warm season grasses. These grasses should be used when enhancing wildlife habitat is a goal of the riparian planting. Spring planted seed should be treated with a cold wet chill process to maximize germination. Fall plantings should be planted with a lightly sowed cool season annual to hold the soil and do not need the wet chill process. To improve wildlife habitat existing stands of fescue can be killed using an appropriate herbicide and warm season grasses can be no -till planted into the sod. Omit fertilizer when establishing native grasses, fertilizer can be applied the second year to improve the stand. Fall, SpringSeeding eeding Per 1000 sq. ft.
