Mitigation Sites This project has utilized a planning process and mitigation sequencing that takes into account the February 1990 Memorandum of Agreement between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army (Army) concerning the determination of mitigation under the Clean Water Act Section 404(b)(1) guidelines. Efforts were made to locate and identify the least environmentally damaging practicable alternative that met the stated project purposes. Preliminary study lines (Refer to Figure 3) were identified and wetland involvement determined for each. The alignment which had the least wetland involvement was chosen in order to avoid, to the:•maximum extent practicable, potential impacts. After determining that wetlands takings could not totally be avoided with this project, steps were taken to minimize the adverse impacts as much as feasible. Project modifications included (1) reduction of right of way from 164 feet to 120 feet through the affected wetlands, (2) reduction of pavement lane widths from 12 feet to 11 feet to accommodate a reduced cross- section (3) elimination of the roadway median, (4) use of the steepest embankment slopes practical in this area (2:1), and (5) lowering of the proposed roadway grade to reduc3ion-of h of embankment. Compensation for the unavoidable loss o 2.7 cres of wetlands is proposed through the restoration and wetlands contiguous to this site. Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off-site wetlands and flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for wetlands losses within the same site. These sites, as shown on Figures 4a and 4b, were chosen for their potential to both recover flood storage taken by the roadway embankment and remain in close proximity to the areas of wetland losses. Table 8 lists the specific sites in priority with the estimated acres (wetlands) and acre-.feet (flood storage) noted. These sites are listed as potential mitigation areas. Actual acreages of wetlands impacted and cubic yards of roadway fill required within the flood storage basin will be determined in the final design phase. Coordination with the appropriate agencies for a Section 404 permit will be completed prior to agreement on specific sites and mitigation measures for this project. Approval to use lands within the 100-year floodplain (Wake County 47 f J I r 4 1? I-I N,? --?-H v 4 property) to mitigate flood storage and wetlands impacts has been advanced by the Wake County Board of Commissioners on July 2, 1990 (refer to letter of August 22, 1990 from Wake County in Appendix C). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surround-ing terrain. A total loss of approximately 2.7 acres of wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 4a and 4b. Sites lA and 1B include approximately 2.0 acres immediately adjacent both sides of Crabtree Creek. Site 1A includes the western levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Area 1B includes the levees of Congoree soil on the east bank between the creek channel and slackwater sloughs or tributary stream channels entering Crabtree Creek. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating here (Sites lA and 1B) would provide an opportunity to restore bottomland forest similar to that proposed for clearing to accommodate the project. Grading 3.5 feet or more of the existing surface material would reduce existing banks to match the surrounding bottomland contour, where saturated conditions generally prevail. After grading is complete, wetland tree species such as River birch (Betula nigra), Green ash (Fraxinus pennsylvanica), Overcup oak (Quercus 1 rata), and Swamp chestnut oak (Quercus michauxii), should be planted to compensate for forested wetland removed along the new causeway. Sites 2 and 7, located approximately 1,400+ feet northeast of the proposed ROW, includes 3.3 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface., Observation in May and June, hence during the current growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline Juncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that 48 T.. grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area. between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. _ Due to the distance from the project and its small size, Site 3, (not shown) consisting of 0.2 acres has been rejected as a feasible mitigation site. Site 4, contiguous with Site 1A, also contains the Altavista soil discussed previously in connection with Site IA. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species, as in Site IA. The same species of oaks and river birch are proposed for planting here as required.

These sites could be graded down an average of 2.5 feet to further offset flood storage capacity loss and mitigate wetlands with a similar scheme as noted for sites 2 and 7. 49 E t As noted in Table 8 the total flood storage capacity recovered with sites 1A, 1B, 2, 5, 6 and 7 is estimated at 15.6 acre-feet. Additional recovery may or may not be needed to achieve the 18.2 acre-feet depending upon final design calculations. Should additional storage be required, Site 4 is proposed' to be used only as needed to mitigate the remaining flood storage capacity deficit. B. Permit Coordination i In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolly (U. S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 404 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the current federal goal of no overall net loss of wetland values and functions. C. Monitorinv Plan As part of the mitigation effort for this specific project a monitoring plan to insure that permit conditions are complied with will be developed by the N. C. Department of Transportation in coordination with the Corps of Engineers. r t- I r r r so r 7 --- STUDY LINES --- mmw??

Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off-site wetlands end flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for hardwood wetlands losses within the same site. These sites, as shown on Figures 1 and 2 (attached) were chosen for their potential to both recover flood storage taken by the roadway embankment (approximately 18.2 acre-feet) and remain in close proximity to the areas of wetland losses. Table 1 lists the specific sites designated for hardwood wetlands creation in priority with the estimated acres (wetlands) and acre-feet (flood storage) noted. Table 2 shows the additional sites of marsh type 1 wetlands creation. These sites are listed as proposed mitigation areas. Actual acreages of wetlands i cted and cubic yards of roadway fill required within the flood- storage basin will be determined in the final esign p ase. Coordination with the appropriate agencies for a Section 404 permit has been in progress for over one year and mutual agreement on sites and mitigation measures should be achieved with this plan. Wake County Board of Commissioners on July 2, 1990 approved the use of lands within the 100-year floodplain (Wake County property) to mitigate flood storage and wetlands impacts associated with the Evans Road Extension project (refer to letter of August 22, 1990 from Wake County in Appendix C of State EA/FONSI). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, partially as a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surrounding terrain. A total loss of approximately acres of bottomland hardwood wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 1 and 2. -Site L-k includes approximately 0.91 acres immediately adjacent to the north side of Crabtree Creek. Site 1A includes the levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating on Site 1A would provide an opportunity to restore bottomland forest similar to that proposed for clearing to accommodate the project. Grading 3.5 feet or more of the existing surface material would reduce the existing bank to match the surrounding bottomland contour, where saturated conditions generally prevail. After grading is complete, wetland tree species such as River birch (Betula niM), Green ash (Fraxinus pennsvlvanica), Overcup oak ( uercus lvrata), and Swamp chestnut oak ( uercus michauxii), will be planted to compensate for forested wetland removed along the new causeway. The wetland reforestation shall be implemented as noted in the attached Project Special Provisions for Wetland Reforestation and Grading. Site 4A and 4B consists of 2.39 and 0.51 acres respectively just north of Site IA and also contains the Altavista soil discussed previously in connection with Site IA. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species. The same tree species as in site 1A are proposed for planting on Site 4A and 4B. 2 TABLE 1 Proposed Wooded Wetlands/Flood Storage Mitigation Sites (Refer to Figures 1 and 2) Mitigation Wetlands Flood Storage Site Acres Acre-feet lA 0.91 3.19 4A 2.39 9.56 413 0.51 2.04 8 2.66 6.65 TOTAL 6.47 21.44 TABLE 2 Additional Flood Storage Mitigation Sites with Supplemental Marsh Wetlands Marsh Mitigation Wetlands Flood Storage Site Acres Acre-feet 2 2.38 3.57 5 1.20 3.00 6 0.30 0.75 7 0.90 1.35 TOTAL 4.78 8.67 Site 8 is found approximately 2400 feet south (upstream) of the project comdor (refer to Figure 2). Site 8 totals 2.66 acres and is contained within the 100 year floodplain, owned by Wake County. This site was examined on January 24, 1992 by our biologist, Gary Plank, to determine whether the hydrology and soils present were conducive for wetland creation and if conducive, the extent of excavation required to insure successful mitigation. This site is mostly at or below the 100-year flood level (284.9 ft) but exhibits characteristics markedly different from the surrounding area. On a portion of the floodplain slightly higher and noticeably drier than immediately surrounding areas, this site is currently occupied by a mature loblolly pine stand. Adjacent floodplain areas to the south, north and west are dominated by bottomland hardwoods, with cane occurring in scattered lower lying places. Tree species occurring in these adjacent areas include Yellow-Poplar, River Birch, Green Ash, Willow Oak, and Sweetgum. To the east, the site is bordered by a west facing slope and the mouth of a ravine formed by an intermittent drainage. In the pine stand itself, dead river birches (8-10 in. DBH) occur in several places, but most of the areas dominated by pine are now either pure pine or include scattered poplars and sweetgums. Eight test holes were dug at locations (Fig. 2) where vegetation indicators suggested that differing hydrological and soil characteristics might be observed (Table 3). Data gathered on the site and shown in Table 3 suggest that this site can be converted to a functioning wetland dominated by bottomland hardwood species, if proper measures are taken to assure success. The soils on the site are clearly alluvial in origin--either Chewacla or Congoree--a result of historical stream migration and associated sediment deposition. While the Wake County Soil Survey indicates Chewacla soils across much of the Crabtree floodplain, Congoree also occurs here and, based on field observations (Table 3), appears to be the more likely soil on this site. Adjacent to the proposed site on the north, however, an intermittent drain exhibits markedly different soil conditions more indicative of Wehadkee soil (Holes #1 and #8), with its darker gray color and increased saturation.

Similarly, Hole #4 indicates the western extent of the mitigation area, where the pine stand 4 has given way to bottomland hardwoods, with soils beginning to exhibit hydric conditions. The southern extent of the mitigation site corresponds to the limit of the pine stand, at about line stake 1-138 (Fig. 2). The site is fed by intermittent drains from relatively steep slopes to the east. As indicated by the hydrology observed in Holes #1, 4, 5, and 8, saturated conditions prevail in areas adjacent to the proposed mitigation site. The westernmost holes appear to reflect subsurface influence of Crabtree Creek and drainage from the ravine southeast of the site. The objective of this mitigation is to create hardwood wetlan habitat n site currently dominated by mature pines, thereby mitigating loss of equivalent a itat in the proposed Evans Road corridor. Several points bear consideration in proposing site 8 and the following procedures. First, areas adjacent the pine stand are obviously exhibiting wetland characteristics, including development of hydric conditions in soils essentially the same as the soil beneath the pine stand. Second, the mature pines currently on the proposed site have effectively dried the soil through years of active transpiration. Removing these mature pine trees will have an immediate impact on the site's hydrology, reducing transpiration potential and thereby lengthening the hydroperiod following rainfall episodes. Third, the presence of dead River Birches of significant diameter suggests that at one time the proposed site was wetter than it is now and that stand composition may have been correspondingly different. Finally, it should be noted that the observations recorded in Table 3 were made during a time when winter rainfall had been markedly below levels typical of this region. In any case, current soil conditions must be altered by grading to reduce depth of subsoil material, thus the overall contour of the proposed site. Removing 3.0 feet of the existing material would reduce the site contour to a level below the surrounding botton land contour, where saturated conditions generally prevail. In the removal process, surface humus and topsoil material would be retained for redistribution on. the excavated site following removal of the lower soil layers. Replacement of 0.5 to 1.0 ft of topsoil and humus material would provide a hospitable medium for tree planting. After surface replenishment is complete, tree species such as River Birch (Betula niQra Green Ash (Fraxinum pennsvlvanica), Overcup Oak ( uercus Ivrata), Swamp Chestnut Oak ( uercus michauxii), Blackgum (Ntvssa svlvatica), and Willow Oak ( ilercus hp ellos L.) would be planted. Appropriate planting density. and species composition will be as proposed previously with Site 1A, 4A and 4B. It is further proposed that to the extent possible, drainage from Weston's future upland development sites just east of this mitigation area be channeled into this area to augment naturally occurring drainage. Channeling stormflows in this manner will not only help irrigate the site but will also allow filtration of runoff from paved surfaces before stormflows enter the nearby Crabtree Creek and lake system. Appropriate monitoring of stand growth will be maintained by NCDOT, as indicated with the attached monitoring plan. Growth rates of bottomland hardwood plantations along S Richland Creek on NCSU's Schenck Forest (part of the Crabtree Creek watershed) indicate that under controlled conditions on a wet site, 1.0 ft. seedlings of the proposed species will reach average heights of 6.0 ft. three to five years after planting. On slightly drier adjacent areas of the same site, growth rates have been even better. Sites 2 and 7, located approximately 1,400 + feet northeast of the proposed ROW, includes 3.3 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface. Observation in May and June, hence during the growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline Juncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. Natural succession of juncus and carex species is expected on these sites. Sites 6 and 6 are wooded upland areas, between the sewerline easement and the lake, adjacent to sites 2 and 7 respectively. These sites would be graded down an average of 2.5 feet to further offset flood storage capacity loss and to offer supplemental wetlands mitigation with a similar scheme as noted for sites 2 and 7. As noted in Table 1 the total flood storage capacity recovered with sites 1,\, 4A, 4B, and 8 is estimated at 21.44 acre-feet. Additional recovery will probably be needed depending upon final design calculations. Additional storage is proposed with sites 2, 5, 6 and 7 providing 8.67 acre-feet of flood storage as noted in Table 2 for the Crabtree svstem. The offering of marsh type wetlands on these sites totals 4.78 acres and is proposed only as supplemental wetlands mitigation. Permit Coordination In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolley (U.S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 4a4 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the current federal goal of no overall net loss of wetland values and functions. Monitoring Plan As part of the mitigation effort for this specific project a revised monitoring plan to insure that permit conditions are complied with has been developed by the N.C. Department 6 of Transportation in coordination with the Corps of Engineers and is attached. In addition, Project Special Provisions for Wetland Reforestation and Grading to be used on this project are also attached. \90004.011Rev;viitig.Pln i ^C) ra?- 1Y t `Sn 1.°°21 ? ?„? `ND '2ROJECT z/ --?

Box 17004, Raleigh, North Carolina 27619 Silverton, Inc., ATTN: Mr. Frank Robuck, Jr., Post Office Box 17102, Raleigh, North Carolina 27619 I. Proposed Project: The permittee proposes to place approximately 41,900 cubic yards of clean fill material into wetlands adjacent to Crabtree Creek, at the upper end of Lake Crabtree, for construction of approximately 1,500 feet of a four-lane public highway. The new highway extends the existing Evans Road approximately 3,500 feet to the northwest from where it currently ends at Weston Parkway (S.R. 1653), across Crabtree Creek to Aviation Parkway (S.R. 1002). The proposed highway embankment will be an average of approximately 95 feet wide (maximum 118 feet), bottom width, where it crosses the wetlands, requiring the loss of approximately 2.64 acres of bottomland hardwood wetlands. The embankment includes a 3 feet wide extension for a proposed Wake County greenways trail which will connect to other proposed trails on the upland. The embankment will also include four culverts: one 24- inch, two 30-inch, and one 66-inch. Approximately 95 cubic yards of clean earth fill will be placed below ordinary high water to relocate a tributary to Crabtree Creek, and stone riprap would be placed within Crabtree Creek to facilitate a bridge crossing. To compensate for the proposed wetlands loss, the applicant proposes to restore and create a total of approximately 6.47 acres of bottomland hardwood wetlands. The applicant proposes to grade, and plant with wetlands tree A species, 4 upland pine and mixed pine/hardwood areas contiguous with Crabtree Creek's adjacent-wetlands and floodplain. Mitigation grading would involve excavation of the sites from three to four feet in depth, and replacement of 6 to 12 inches of topsoil/humus to elevations approximately equal to the existing natural bottomlands. The compensation sites would be monitored for viability for a minimum period of three years following planting, and in cases of unacceptable findings, the permittees would consult with the Corps of Engineers to determine appropriate recourse options. 4.78 acres of additional -2- upland areas along the southeastern shore of Lake Crabtree would also be excavated, to the elevation of the emergent wetlands on the lake, for additional flood storage mitigation. These areas are expected to propagate additional emergent marsh vegetation. The purpose of the work is to provide for the construction of a new north-south corridor to satisfy heavy traffic demand in the area, and provide access to a rapidly growing area. II. Alternatives [40 CFR 230.10]: (1) Improving Existing Roadways: This alternative would involve widening NC 54 and North Harrison Avenue to multi-lane roadways to handle projected traffic growth. The projected increased usage of North Harrison Avenue would cause breakdown condition at its interchange with I-40. This alternative would not provide additional access to the large new developments already underway along Weston Parkway, Evans Road, and the future Cary Parkway. Capacity analysis of this alternative reveals unacceptable Level of Service ratings by the design year (2010). The Greater Raleigh Urban Thoroughfare Plan, a transportation plan showing the comprehensively planned development of the area, shows Evans Road replacing NC 54 as a primary thoroughfare, which this alternative would circumvent. Future widening of NC 54 is probably not feasible (cost effective). Cost analysis shows an approximately doubled cost ($4,000,000 more) for widening NC 54 as compared to the proposed project. Based on the above information, it has been determined that this alternative is not a reasonably available alternative which would accomplish the project purpose and satisfy the project needs. (2) Other Alignments: This alternative would involve putting the proposed roadway on a different alignment to cross Crabtree Creek. Based on the available information, the proposed alignment crosses the Crabtree Creek floodplain at a point where the impacted wetlands are the minimum possible. Also, the proposed alignment allows a connection with the existing Evans Road, which provides for improved traffic flow and safety. Based on the above, this alternative would not have less adverse effect on the aquatic ecosystem. (3) No action: This alternative would likely result in severely congested or breakdown conditions on North Harrison Avenue and NC 54, based on projected traffic growth . These roadways are primary thoroughfares for the area. It is expected that extreme congestion during peak hours would be commonplace and the duration of peak periods would lengthen with time. This alternative is not consistent with local, regional, or state transportation goals. Impacts to the aquatic ecosystem would be eliminated by this alternative; however, the project purpose and need would not be met. (4) Narrower roadway: The proposed roadway calls for construction of a median on the portions that are not within wetlands; it has been deleted form wetland portions to minimize the impacts to the aquatic ecosystem. The -3- proposed pavement lane width through wetlands has been reduced from 12 to 11 feet, and the fill embankments have been modified to the steepest practical slope (2:1) through wetlands. The proposal is expected to be a major thoroughfare; therefore, eliminating lanes to reduce the roadway width would not accomplish the project purpose. (5) Elevated (non-fill) greenway trail: This alternative would require that the structures be designed to avoid uplifting or floating during extended periods of inundation, per Wake County requirements. It would also require at least a temporary disturbance of the wetlands that are in the vicinity of the trail construction area. Due to the additional cost and special construction requirements associated with this alternative, it has been determined that it is not a practicable alternative. III. Technical Evaluation Factors Considered: A. Physical/chemical characteristics and anticipated changes: Substrate: 2.64 acres of waters of the U.S., including wetlands, would be filled for the proposed project. The impact includes relocation of a tributary to Crabtree Creek, and placement of stone riprap within Crabtree Creek to stabilize the bank for bridge construction. The substrate in the wetlands and tributary would be permanently adversely modified; however, it is expected that the relocated tributary would eventually "naturalize" to some extent to replace the lost creek bottom. Currents, circulation or drainage patterns: Drainage patterns within the floodplain, and the Crabtree Creek tributary will be permanently altered by the project. The roadway would have four culverts which are expected to maintain flows and drainage through the fill. It is not expected that the work on Crabtree Creek will substantially change its drainage characteristics. Suspended particulates; turbidity: Construction of the proposal will result in increased turbidities adjacent to and downstream of the work areas. This degradation of water quality should only be minor and of short duration provided appropriate sedimentation control measures are implemented. Although the additional hard surface development may increase turbidity in the area, no substantial long-term turbidity impacts are expected. Water quality (temperature, salinity patterns and other parameters): Although run-off from the proposed roadway would enter the waterways directly and indirectly, the proposal is not expected to substantially modify water temperature or chemical make-up of waters effected by the construction. A Water Quality Certification has been issued for this project. -4- Flood control functions: The proposed project encroaches 1,500 feet perpendicularly across the Crabtree Creek 100-year floodplain. Hydraulic analysis shows that the proposed bridge and roadway will increase the upstream 100-year flood a maximum of 0.8 to 1.0 foot. The roadway cross-section width and elevation has been reduced to the maximum extent possible, and the unavoidable 18.2 acre-feet of fill within the floodplain will be mitigated by the excavation of approximately 30.11 acre-feet within the floodplain for flood storage. Storm, wave and erosion buffers: No appreciable effect on these factors is anticipated. Erosion and accretion patterns: The proposal calls for riprap erosion protection at the bridge embankments on Crabtree Creek. Some short- term adverse impacts would be anticipated during the construction phase of the project. Sedimentation and erosion control measures are proposed and should be maintained throughout the life of the project, in accordance with state and local regulations. Aquifer recharge: No anticipated effect. Baseflow: No anticipated effect. Additionally, for projects involving the discharge of dredged material into open water: Mixing zone, in light of the depth of water at the disposal site; current velocity, direction and variability at the disposal site; degree of turbulence; water column stratification; discharge vessel speed and direction; rate of discharge; dredged material characteristics; number of discharges per unit of time; and any other relevant factors affecting rates and patterns of mixing: Not applicable. Discharges involve stable material such as riprap or will be done after dewatering of disposal site. B. Biological characteristics and anticipated changes. Special aquatic sites (wetlands, mudflats, coral reefs, pool and riffle areas, vegetated shallows, sanctuaries and refuges, as defined in 40 CFR 230.40-45): The wetlands to be impacted by the pit expansion consist of three different plant communities: branch bottomlands that have been cleared, cultivated and allowed to revert to forest several times in the last century, and maintained sewer and gas right-of-ways. The branch bottomlands overstories are vegetated primarily by river birch ( etu nigra), sycamore (Platanus occidentalis), yellow poplar (Liriodendron tulipifera), sweetgum (Liq-uidambar sttyraciflua), and red maple (Acer rubrum). The utility right-of- -5- e. Elevated (non-fill) greenway trail: This alternative would require that the structures be designed to avoid uplifting or floating during extended periods of inundation, per Wake County requirements. It would also require at least a temporary disturbance of the wetlands that are in the vicinity of the trail construction area. Due to the additional cost and special construction requirements associated with this alternative, it has been determined that it is not a practicable alternative. Summary: I have reviewed the application and plans furnished by the applicant and the environmental assessment. I am aware that the project would involve the loss by filling of approximately 2.64 acres of bottomland hardwood wetlands for construction of a for construction of approximately 1,500 feet of a four-lane public highway. To compensate for the proposed wetlands loss, the applicant proposes to restore and create a total of approximately 6.47 acres of bottomland hardwood wetlands. I do not consider these impacts significant due to their nature, and the replacement of lost functions by the compensatory mitigation. The proposed project has had extensive review through our normal public notice process. Agency comments received on the proposal include the following: a. A Coordinated State Viewpoint was received for the project on May 1, 1991. The State Natural Heritage Program recommended denial, based on a lack of justification for the project need, and the project impacts to the natural environment. The Wildlife Resources Commission recommended denial, based on non-wetlands dependency, lack of alternatives investigation, non- selection of the least environmentally damaging alternative, and lack of suitable mitigation. The State Department of Community Assistance also commented on the lack of justification for the project need. On September 12, 1991, the State confirmed that its recommendations had not changed. By letter dated July 13, 1992, the Wildlife Commission submitted the final Coordinated State Viewpoint, recommending denial based on non-selection of the least damaging alternative, non-wetlands dependency, and failure to avoid and minimize environmental impacts to the extent possible. The Wildlife Commission also made several recommendations concerning the proposed ` compensatory mitigation plan and its monitoring. i b. A State Water Quality Certification, No. 2743, was issued for the proposed work by the N.C. Division of Environmental Management on June 17, 1992. C. The U.S. Fish and Wildlife Service, by letter dated July 2, 1992, concurred that the proposed mitigation will adequately compensate for fish and wildlife values that will be lost due to project construction, and recommended a condition that the proposed mitigation commence prior to, or at least concurrent with, project construction. -6- d. The U. S. Environmental Protection Agency by telephone conversation of July 1, 1992, stated that they have no objection to issuance of a permit for the proposed work. e. The National Marine Fisheries Service has reviewed this application and submitted no comments. I have reviewed the application and plans and the public interest record, and I find that the proposed work is not controversial and will not have a significant effect on the quality of the human environment. An evaluation of the EPA's 404(b)(1) guidelines, 40 CFR Part 230, has been performed. I have determined that the proposed discharge of fill material complies with the guidelines with the inclusion of appropriate special conditions. I find that this application is not a major Federal action significantly affecting the human environment; and hence, the preparation of a detailed statement under Section 102(2)(c) of the National Environment Policy Act of 1969 is not required. I have given full consideration to this application. After weighing favorable and unfavorable aspects, I find that the issuance of a permit to the North Carolina Department of Transportation, Division of Highways; North Hills Properties, Inc.; and Silverton, Inc.; will not be contrary to the general public interest provided that it adheres to the conditions incorporated in the permit. lter S.

The roadway would have four culverts which are expected to maintain flows and drainage through the fill. It is not expected that the work on Crabtree Creek will substantially change its drainage characteristics. Suspended particulates; turbidity: Construction of the proposal will result in increased turbidities adjacent to and downstream of the work areas. This degradation of water quality should only be minor and of short dtitation provided appropriate sedimentation control measures are implemented. Although the additional hard surface development may increase turbidity in the area, no substantial long-term turbidity impacts are expected. Water quality (temperature, salinity patterns and other parameters): Although run-off from the proposed roadway would enter the waterways directly and indirectly, the proposal is not expected to substantially modify water temperature or chemical make-up of waters effected by the construction. A Water Quality Certification has been issued for this project. -4- Flood control functions: The proposed project encroaches 1,500 feet perpendicularly across the Crabtree Creek 100-year floodplain. Hydraulic analysis shows that the proposed bridge and roadway will increase the upstream 100-year flood a maximum of 0.8 to 1.0 foot. The roadway cross-section width and elevation has been reduced to the maximum extent possible, and the unavoidable 18.2 acre-feet of fill within the floodplain will be mitigated by the excavation of approximately 30.11 acre-feet within the floodplain for flood storage. Storm, wave and erosion buffers: No appreciable effect on these factors is anticipated. Erosion and accretion patterns: The proposal calls for riprap erosion protection at the bridge embankments on Crabtree Creek. Some short- term adverse impacts would be anticipated during the construction phase of the project. Sedimentation and erosion control measures are proposed and should be maintained throughout the life of the. project, in accordance with state and local regulations. Aquifer recharge: No anticipated effect. Baseflow: No anticipated effect. Additionally, for projects involving the discharge of dredged material into open water: Mixing zone, in light of the depth of water at the disposal site; degree of current velocity, direction and variability at the disposal site; turbulence; water column stratification; discharge vessel speed and direction; rate of discharge; dredged material characteristics; number of discharges per unit of time; and any other relevant factors affecting rates and patterns of mixing: Not applicable. Discharges involve stable material such as riprap or will be done after dewatering of disposal site. B. Biological characteristics and anticipated changes. Special aquatic sites (wetlands, mudflats, coral reefs, pool and riffle areas, vegetated shallows, sanctuaries and refuges, as defined in 40 R CFR 230.40-45): The wetlands to be impacted by the pit expansion consist of three different plant communities: branch bottomlands that have been cleared, cultivated and allowed to revert to forest several times in the last century, and maintained sewer and gas right-of-ways. The branch bottomlands overstories are vegetated primarily by river birch ( to nigla_), sycamore ( ata u occidenta is), yellow poplar (T.iriodendron rulivifera), sweetgum (LigUidambar styraci&"ua), and red maple (Acer rubrum)• The utility right-of- -8- iii.

Franklin Vick, P.E., Manager Planning and Environmental Branch North Carolina Department of Transportation Post Office Box 25201 Raleigh, North Carolina 27611-5201 Dear Mr. Vick: n l* o y 2n ?n This correspondence is in reference to the monitoring requirements contained in the subject Department of the Army Permit, issued to the North Carolina Department of Transportation (NCDOT) on August 17, 1992, for work at the Evans Road Extension mitigation sites, associated with the Evans Road (SR 1653) highway project located adjacent to Crabtree Creek in Wake County, North Carolina (TIP Nos. U-2403, State Project No. 9.8050364). A review of NCDOT's revised and approved mitigation plan for this highway project reveals that your staff was to have: a. established permanent vegetative sample plots and conduct inspections of those plots prior to planting, at the completion of planting (including an "as-built" report), and August- September of every growing season until vegetative success criteria has been met. b. installed monitoring wells to document compliance and to document the hydrology parameter for this project, previously established as saturated within 12 inches of the surface, ponded or flooded for at least 26 consecutive days of the growing season, for the first year under reasonably average climatic conditions. C. monitored the vegetative survival rate at a minimum of 320 stems per acre of living trees for three years without size/height specifications. Special Condition (a.) of the subject permit states that NCDOT's Revised (##3) Mitigation Plan, dated June 2, 1992, will be implemented in its entirety and that the following conditions shall also be implemented as part of the mitigation plan: Printed on IS Recycled Paper -f, -2- (1.)

Construction of the mitigation sites will be initiated at such time to provide for planting of seedlings the first suitable planting period (November 15 through March 15) following commencement of project construction. Conversations with Mr. Eric Alsmeyer of my regulatory staff reveals that, although your staff did submit the required monitoring data for calendar year 1995, as of this date, we have not received the calendar year 1996 monitoring report for the work at the Evans Road Extension site. Your staff's failure to provide the required monitoring report has put NCDOT in noncompliance with the terms and conditions of the subject permit. By copy of this letter, you are hereby directed to provide us with the 1996 annual monitoring report for the Evans Road Extension Mitigation Site by March 21, 1997, or I will have no recourse but to pursue enforcement action against the North Carolina Department of Transportation for permit noncompliance. (Please refer to Pages 10 and 11 of the mitigation plan for specifics regarding the required data.) Failure to comply with this request may result in referral to the United States Attorney with a recommendation for appropriate action, including the potential for an administrative fine. Thank you for your time and cooperation. If you have any questions, please call Mr. Alsmeyer at the Raleigh Regulatory Field Office, telephone (919) 876-8441, extension 23. Sincerely, Mic ael D.

Mitigation occurred on-site at eight locations. Sites IA, 4A, 413, and 8 were restored as bottomland forest. On sites 2, 5, 6, and 7, marsh type wetlands were created (Figures 1 and 2). 1.2 Purpose Monitoring of the Evans Road site is required to demonstrate successful mitigation. Monitoring of wetlands for success criteria falls under two categories: hydrology and vegetation. The following report describes the results of the hydrologic and vegetative monitoring during 1997 at the Evans Road Mitigation Site. 2.0 HYDROLOGY 2.1 Success Criteria In accordance with federal guidelines for wetland mitigation, the success criteria for hydrology states that the area must be inundated or saturated (within 12" of the surface) by surface or ground water for at least 12.5% of the growing season. The growing season in Wake County begins March 26 and ends November 6. The dates marking the start and end of the growing season were based on information gathered from The National Weather and Climate Center (http: //www. wcclnres. usda.gov/water/wetlands. htmo. These dates correspond to a 50% probability that air temperatures will drop to 28° or lower after March 26 and before November 10 thus the growing season is 229 days. 2.2 Hydrologic Description Eleven monitoring wells, two rain gauges, and one surface water gauge were installed on site (Figure 3). Data was collected on a daily basis. Rain data and depth to groundwater readings were recorded by automatic monitoring wells and gauges. All monitoring wells, rain gauges, and surface water gauges were installed prior to March 26 thus data collection spanned the entire growing season. Appendix 1 contains a plot of the water depth for each monitoring well and surface gauge. Precipitation events are included on each graph as bars. 1 2.3 Results of Hydrologic Monitoring The total number of days that the groundwater was within twelve inches of the surface was determined for each well. This number was converted into a percentage of the 224-day growing season. The results are presented in Table 1.

The site contains creation of the following plant communities: Wooded Wetland/Flood Storage ( approximately 5.4 acres) Fresh Marsh/Flood Storage (approximately 3.7 acres) 2 The site was planted in March 1994, March 1995, and March 1996. Of the 9.1 acres on the site, approximately 5.4 involved tree planting. There were ten plots established throughout the site, encompassing all plant communities. 3.3 Results of Hydrologic Monitoring The initial number of trees within in each vegetative plot was counted in March 1996. The number of trees surviving within each plot after the first growing season was counted in September 1996. The number of trees within each plot after the second growing season was counted in October 1997. The results of the second growing season are shown in Tables 2 and 3 TABLE 2 - Vegetative Monitoring Results (Trees) totals/(avg) Plot # Trees(p) Trees % Survival Density/acre la - 1 25 51 204.0% 1387 4a - 1 25 21 84.0% 571 4a - 2 25 21 84.0% 571 4b - 1 25 33 132.0% 898 8 - 1 25 14 56.0% 381 8 - 2 25 11 44.0% 299 (6 plots) 25.0 25.2 100.7% 685 TABLE 3- Vegetative Monitoring Results (Grasses) Plot # % Coverage 2/5 - 1 90.0% 2/5 - 2 90.0% 2/5 - 3 95.0% 6/7 - 1 85.0% totals/(avg) (4 plots) 90.0% Notes from Report • Sites la, 4a, and 4b were replanted and tree protectors installed on all trees in March 1996. Previous report from September, 1995 indicated beaver depredation on trees not having tree protectors. Several dead tree seedlings located in tree protectors that were randomly installed throughout planted areas. • Plot 1 a - 1 has many river birch naturally invading (approximately 40 were identified within the plot). Green ash was doing well, overcup oak doing fair. This plot was located in the wettest portion of the site. • Plot 4a - 1 has river birch, green ash, overcup oak, and willow oak present within the plot. Several black willow were identified (approximately 5) naturally invading in this plot. • Plot 4a - 2 has green ash, overcup oak, and willow oak present. Only one black willow was identified within this plot. 3 • Plot 4b - 1 is showing good success. River birch, green ash, overcup oak, cherrybark oak, willow oak, and water oak exist within the plot. Several black willow were naturally invading (approximately 15 identified within the plot). • Plots 2, 5 ,6, and 7 are fresh water marsh/flood storage areas which were allowed to naturally regenerate with fresh-water march species. These sites have a variety of species located on them including juncus, cattail, and sericea lespedeza. 4.0 CONCLUSIONS 4.1 Hydrology The groundwater was within twelve inches of the surface for at least 12.5% of the growing season in all wells. 4.2 Vegetation The overall average density of trees was 100.7%. This is equivalent to 685 trees/acre in areas replanted in spring of 1996, greater than the 320 tree/acre minimum success criteria. Sites 2, 5, 6, and 7 have an average coverage of 90% in freshwater marsh species. 5.0 RECOMMENDATIONS • Continue annual monitoring of site hydrology through the growing season (March 26 to November 10). • Continue annual vegetative monitoring. 4 fl t 1 y ' (1 oo . t ......... . „ = r . ,1 ti t, -- ' 'O:, 11 1 111':'I'1,11111? ? -? 1 > • // >: ? ? ?? . 1 I I ' I' ] c ; l!

Efforts were made to locate and identify the least environmentally damaging practicable alternative that met the state project purposes. Preliminary study lines were identified and wetland involvement determined for each. The alignment which had the least wetland involvement was chosen in order to avoid, to the maximum extent practicable, potential impacts. After determining that wetlands takings could not totally be avoided with this project, steps were taken to minimise the adverse impacts as much as feasible. Project modifications included (1) reduction of right of way from 164 feet to 120 feet through the affected wetlands, (2) reduction of pavement lane widths from 12 feet to 11 feet to accommodate a reduced cross-section (3) elimination of the roadway median, (4) use of the steepest embankment slopes practical in this area (2:1), and (5) lowering of the proposed roadway grade to reduce width of embankment. Compensation for the unavoidable loss of 2.7 acres of wetlands is proposed through the restoration and creation of wetlands contiguous to this site. Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off-site wetlands and flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for wetlands losses within the same site. These sites, as shown on Figures 4a and 4b, (of the State EA/FONSI) were chosen for their potential to both recover flood storage taken by the roadway embankment (approximately 18.2 acre- feet) and remain in close proximity to the areas of wetland losses. Table 1 lists the specific sites in priority with the estimated acres (wetlands) and acre-feet (flood storage) noted. These sites are listed as proposed mitigation areas. Actual acreages of wetlands impacted and cubic yards of roadway fill required within the flood storage basin will be determined in the final design phase. Coordination with the appropriate agencies for a Section 404 permit will be completed prior to agreement on specific sites and mitigation measures for this project. Approval to use lands within the 100-year floodplain (Wake County property) to mitigate flood storage and wetlands impacts has been advanced by the Wake County Board of Commissioners on July 2, 1990 (refer to letter of August 22, 1990 from Wake County in Appendix C of State EA/FONSI). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surrounding terrain. A total loss of approximately 2.7 acres of bottomland hardwood wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 4a and 4b. Sites 1A and 1B include approximately 2.0 acres immediately adjacent both sides of Crabtree Creek. Site 1A includes the western levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Area 1B includes the levees of Congoree soil on the east bank between the creek channel and slackwater sloughs or tributary stream channels entering Crabtree Creek. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating here (Sites 1A and 1B ) would provide an opportunity to restore bottomland forest similar to that proposed for clearing to accommodate the project. Grading 3.5 feet or more of the existing surface material would reduce existing banks to match the surrounding bottomland contour, where saturated conditions generally prevail. After grading is complete, wetland tree species such as River birch (Betula nigra), Green ash (Era! nus pennsylvanica), Overcup oak ( uercus data), and Swamp chestnut oak ( uercus michauxii), will be planted to compensate for forested wetland removed along the new causeway. The wetland reforestation shall be implemented as noted in the attached Project Special Provisions for Wetland Reforestation and Grading. Sites 2 and 7, located approximately 1,400 + feet northeast of the proposed ROW, includes 3.3 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface. Observation in May and June,. hence during the current growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline Juncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. Natural succession of juncus and carex species is expected on these sites. Site 4 consists of a minimum of 2.0 acres which is contiguous with Site IA and also contains the Altavista soil discussed previously in connection with Site 1A. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species, as in Site 1A. The same species of oaks and river birch are proposed for planting on Site 4. TABLE 1 Proposed Wetlands/Flood Storage Mitigation Sites (Refer to Figures 4a and 4b) Mitigation Wetlands Flood Storage Site Acres Acre-feet 1A 1.38 4.83 1B 0.59 2.07 2 2.38 3.57 4 2.00 8.00 5 1.20 3.00 6 0.30 0.75 7 0.90 1.35 TOTAL 8.75 23.57 Sites 5 and 6 are wooded upland areas, between the sewerline easement and the lake, adjacent to sites 2 and 7 respectively. These sites could be graded down an average of 2.5 feet to further offset flood storage capacity loss and mitigate wetlands with a similar scheme as noted for sites 2 and 7. As noted in Table 1 the total flood storage capacity recovered with sites 1A, 1B, 2, 4, 5, 6, and 7 is estimated at 23.6 acre-feet. Additional recovery may or may not be needed depending upon final design calculations. Should additional storage be required, Site 4 is proposed to be enlarged beyond the 2.0 acres as needed to mitigate the remaining flood storage capacity deficit. Permit Coordination In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolley (U.S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 404 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the current federal goal of no overall net loss of wetland values and functions. Monitoring Plan As part of the mitigation effort for this specific project a monitoring plan to insure that permit conditions are complied with has been developed by the N.C. Department of Transportation in coordination with the Corps of Engineers and is attached. In addition, Project Special Provisions for Wetland Reforestation and Grading to be used on this project also attached. \90004.01\Mitig.Pln REC' D OCT 2 4 1991 BAKK, INC.

Burton, Adams, Kemp & King FRAMS 2 0 P.O. Box 311 Raleigh, North Carolina 27602-0311 Dear Mr. Lewis: On November 20, 1990 you applied on behalf of North Hills Properties, Inc. for Department of the Army authorization to discharge fill material into wetlands adjacent to Crabtree Creek, for construction of an extension of Evans Road in Cary, Wake County, North Carolina. The application was revised by letter of July 12, 1991 to include the North Carolina Department of Transportation, and Silverton, Inc. In process of reviewing this proposal, we have determined that the proposed mitigation for loss of bottomland hardwood wetlands does not provide appropriate and practicable mitigation for all remaining unavoidable adverse impacts, as my staff has discussed in a previous meeting with you. In order to assist you in formulating an acceptable proposal for appropriate and practical mitigation, we are providing the enclosed "Mitigation Guidelines", which identifies the desirable components of an acceptable bottomland hardwoods mitigation proposal. We have developed these guidelines with input from Federal and State resource agencies, as well as the North Carolina Department of Transportation and other appropriate sources. We recommend that you revise your mitigation plan in accordance with the proposed guidelines, to mitigate for the projected unavoidable losses of waters and/or wetlands, and submit the revised plan for our concurrence. Should you determine that part(s) cf the guidelines are inappropriate or impracticable for your proposal, you should provide specific information to justify that position. As discussed with Ron Hairr of your office, a meeting to allow all the involved parties to discuss your mitigation proposal is tentatively scheduled for 2:00 pm, Friday, August 30, in Room 470 of the Highway Building in Raleigh. Please provide your mitigation submittal to this office by August 22, 1991, with copies to all objecting Federal and State review agencies, to allow minimal time for review before the meeting. Mr. Eric Alsmeyer of my Raleigh Field Office staff, is responsible for processing your application telephone (919) 846-0749.

The following description of the work is taken from data provided by the applicant and from observations made during an onsite visit by representatives of the U.S. Army Corps of Engineers. Plans submitted with the application show the placement of approximately 41,900 cubic yards of clean fill material into wetlands adjacent to Crabtree Creek, at the upper end of Lake Crabtree, for construction of approximately 1,500 feet of a four-lane public highway. The new highway would extend the existing Evans Road approximately 3,500 feet to the northwest from where it currently ends at Weston Parkway (S.R. 1653), across Crabtree Creek to Aviation Parkway (S.R. 1002). The proposed highway embankment would be an average of approximately 95 feet wide, bottom width (maximum 118 feet) where it crosses the wetlands, requiring the loss of approximately 2.64 acres of bottomland hardwood wetlands..- The embankment would include a 3 feet wide extension for a proposed Wake County greenways trail which would connect to other proposed trails on the upland. The embankment would also include four culverts: one 24-inch, two 30-inch and one 66-inch. Approximately 95 cubic yards of clean earth fill would be placed below ordinary high water to relocate a tributary to Crabtree Creek, and stone riprap would be placed within Crabtree Creek to facilitate a bridge crossing. To compensate for the proposed wetlands loss, the applicant proposes to restore and create a total of approximately 6.7 to 12.7 acres of wetlands. The final acreage of compensation area would depend on final design calculations of flood storage capacity and and the further excavation needed to mitigate the storage capacity deficit. The applicant proposes to grade, and plant with wetland plant species, as appropriate, seven areas contiguous with Crabtree Creek's adjacent wetlands. The compensation sites would be monitored for viability for a minimum period of 2 years following planting. Plans for the proposed construction are included with this public notice._ The State of North Carolina will review this public notice to determine the need for the applicant to obtain any required State authorization. No DA permit will be issued until the coordinated State viewpoint on the proposal has been received and reviewed by this agency, nor will a DA permit be issued until the North Carolina Division of Environmental Management (DEM) has determined the applicability of a Water Quality Certificate as required by PL 92-500. ? r -2- This application is being considered pursuant to Section 404(b) of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this worksite is not registered property or property listed as being-eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer has determined, based on a review of data furnished by the applicant and onsite observations, that the activity will not affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, in cumulative impacts, of the proposed activity and its intended use on the public interest: Evaluation-of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards, flood plain values, land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations-of property ownership, and, in general, the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding senten'lp and any other applicable guidelines or criteria, a permit will be grantees unless the District Engineer determines that it would be contrary to the public interest. -3- The Corps of Engineers is soliciting comments from the public; Federal, State, and local agencies and officials; Indian Tribes, and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition, or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above. Comments are used in preparation of an Environmental Assessment and/or Environmental Impact Statement pursuant to the National Environmental Policy_Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this DA permit will not be made until the DEM issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The DEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this public notice for the DA permit serves as application to the DEM for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management, Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management plans to take final action in the issuance of the Clean Water Act certification on or after January 7, 1991. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management, Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before December 31, 1990, Attention: Mr. William Mills. Written comments pertinent to the proposed work, as outlined above, will be received in this office, Attention: Mr. Eric Alsmeyer, until 4:15 p.m., January 14, 1991, or telephone (919) 846-0749. =,r { A tai ?i ? `??'?. 4 fn • ^ ?. ?? $ ,A ISITE . x I.

Suermann District Engineer 16Y AT E F 'D'? <LI " Wilmington District 5 ?- f U.S. Army Corps of Engineers P.O. Box 1890 Wilmington, North Carolina 28402-1890 Dear Lt. Colonel Suermann: This is the report of the U.S. Fish and Wildlife Service (Service) and the Department of the Interior on the Public Notice for Action ID 199100143, dated December 13, 1991. The applicant, North Hills Properties, Inc., proposes to place fill material in 2.64 acres of forested wetlands to construct a proposed extension of existing Evans Road near Morrisville, Wake County, North Carolina. A previous Service report was provided to the N.C. Department of Transportation, Division of Highways, on April 13, 1990, in response to a scoping letter for the proposed project. This report is submitted in accordance with provisions of the Fish and Wildlife Coordination Act (16 U.S.C. 661-667e) and Section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543). It is to be used in your determination of 404(b)(1) compliance (40 CFR 230) and your public interest review (33 CFR 320.4) as they relate to protection of fish and wildlife resources. A Service biologist visited the site on January 21, 1991. Palustrine forested wetlands present are dominated by various species of oaks ( uercus sp.), river birch (Betula ni ra) and other bottomland hardwood tree species. Palustrine emergent wetlands are present also in existing gas pipeline and sewer line rights-of-way which cross the proposed alignment. Vegetation in these areas is dominated by rushes (Juncus spp.), bulrush (Scirpus sp.), cattail (Typha sp.) and various species of grasses and sedges. Draft National Wetland Inventory (NWI) mapping is available for the site and depicts the wetland area in the vicinity of the proposed crossing as palustrine, forested, broad-leaved deciduous, seasonally-flooded. Present in the entire area at the time of the site visit were many pools which likely serve as breeding habitat for numerous amphibians, including chorus frogs (Pseudacris sp.) and salamanders (Ambystoma sp.). The site is part of. what once was a much larger, contiguous bottomland ecosystem adjacent to Crabtree Creek; however, subsequent to NWI mapping of the site, the area downstream of the proposed project site was cleared and converted to open water, now called Lake Crabtree, as part of the U.S. Department of Agriculture, Soil Conservation Service flood control project on Crabtree Creek. Soils underlying the site are predominantly Chewacla hydric soils with some Wehadkee hydric soils also present. According to the Public Notice, implementation of the project, as proposed, will require the fragmentation and filling of 2.64 acres of forested wetlands. Fill is proposed for construction of a proposed four-lane public highway which would extend existing Evans Road approximately 3,500 feet to the northwest from where it current''-•y ends at Weston Parkway (SR 1653) across the floodplain of Crabtree Creek and through the headwaters of Lake Crabtree to Aviation Parkway (SR 1002). The proposed highway embankment would average 95 feet in width with a bottom width of 118 feet across the wetland portions of the alignment. The embankment includes a 3-foot wide extension for a proposed make County greenways trail. Drainage structures proposed in the solid-fill causeway are: one 24-inch, two 30-inch, and one 66-inch culvert. Crabtree Creek ;could be crossed by a bridge and would be channel _`Zed and _?pra.pped for an approximate 200-foot reach at the -ro sling point. Construction as proposed would significantly further fragment one of the last contiguous portions of the extensive palustrine forested wetland ecosystem which existed in the area prior to .onstruction of Lake Crabtree. Construction would also increase noise and disturbance to wildlife using the system and impose a considerable safety hazard to wildlife movement along the Crabtree Creek riparian corridor. The applicant proposes to mitigate for lost Netiand resources 'Oy restoration and creation of approximately 6.7 to 12.7 acres of wetlands adjacent to existing wetlands and in the riparian zone of Lake Crabtree and Crabtree Creek. Final acreage proposed for mitigation would depend on final design calculations of flood storage capacity and the amount of excavation needed to mitigate the flood storage capacity eliminated by emplacement of fill within the flood pool of Lake Crabtree. The applicant proposes to grade seven areas contiguous with existing wetlands and plant wetland species. Monitoring would be performed for two years follo,,71 g punting. Performance criteria are not specified in the Public Notice. Mitigation measures for offsetting the adverse effects of increased noise, disturbance, travel impedance and increased likelihood of wildlife mortality are not addressed in the Public Notice. The Service places considerable value on palustrine forested wetlands. Resident and migratory wildlife may include white-tailed deer, raccoon, red and gray fox, passerine birds, raptors, reptiles and amphibians. This site and its associated habitats are of significant value to wildlife in and adjacent to Lake Crabtree and wetlands adjacent to Crabstree Creek as sites for feeding, cover, migration, nesting and juvenile rearing. Forested wetlands also perform essential water quality functions. They serve in pollution and sediment removal, act as flood water retention sites, and contribute useable nutrients to the aquatic food web. This is especially true in the present case since the site is within the flood pool of a reservoir expressly designed for flood control purposes. A detailed description of this habitat type and its value to fish and wildlife is found in the Service's publication entitled Riparian Ecosystems: Their Ecology and Status (Brinson, M.M., B.L. Smith, R.C. Plantico and J.S. Barclay. 1981. U.S. Fish and Wildlife Service FIWS/OBS-81/17. 155 pp.). Palustrine forested wetland losses are occurring at a high rate on a national basis. In the two decade period between the early 1950's and 1970's palustrine forested wetlands were reduced nationally by 10.8 percent (Frayer, W.E., T.J. Monahan, D.C. Bowden and F.A. Graybill. 1983. Status and Trends of Wetlands and Deepwater Habitats in the Conterminous United States: 1950's to 1970's. U.S. Fish and Wildlife Service, Washington, D.C. 32 pp.). Fully 92 percent of the national losses in palustrine forested wetlands occurred in the southeastern United States (Hefner, J. and J. Brown. 1984. Wetland Trends in the Southeastern United States. Wetlands 4:1-11.). Based on the above-described habitat values and the fact that such areas are relatively scarce or becoming scarce on a national basis or in the ecoregion, the Service's Mitigation Policy (Federal Register 46(15):7656- 7663, January 23, 1981) goal for resources of this type calls for no net loss of in-kind habitat value. After minimizing losses of such habitats, the unavoidable losses should be replaced with similar habitat values so that populations of the species associated with the habitats will remain relatively stable in the area over time. Specific ways to achieve this include: 1) physical modification of replacement habitat to convert it to the same type lost; 2) restoration or rehabilitation of previously altered habitat; 3) increased management of similar replacement habitat so that the in-kind value of the lost habitat is replaced; or 4) a combination of measures. The attached page identifies the Federally-listed endangered (E) species which may occur in the area of influence of this action. The Federally- listed endangered red-cockaded woodpecker (Picoides borealis) may occur within the impact area of the proposed project. If the proposed project will be removing pines greater than or equal to 30 years of age in pine or pine/hardwood habitats, surveys should be conducted for active cavity trees within a 1/2-mile radius of project boundaries. If red-cockaded woodpeckers are observed within the project area or active cavity trees found, the project has the potential to adversely affect the red-cockaded woodpecker, and you should contact this office for further information. In consideration of the high value of the project area to fish and wildlife, we believe the public interest would best be served through impact avoidance. The Service also believes that the proposed work, if authorized, would be contrary to the guidance provided in the U.S. Environmental Protection Agency guidelines for Specifications of Disposal Sites for Dredged or Fill Material (Federal Register 45(249):85344-85357, December 24, 1980), which state that fill shall not be placed in wetlands when alternatives exist. Several upland alternatives to the proposed project appear available. Alternative routing via Weston Parkway, NC 54 and Aviation Parkway, much of it presently four-laned, is already in place. Further, upland habitats adjacent to the wetlands may be developed through access from existing Weston Parkway and Aviation Parkway without the need for the proposed wetland crossing and fill activities. In the unlikely event that the applicant should be able to document that no practicable alternative to the proposed project exists, the Service would be willing to discuss mitigation possibilities; however, based on our site visit, much of the area proposed for use as mitigation is already comprised of functional wetlands. In order to effect fish and wildlife resource conservation and to A. fulfill the public trust in this matter, the Service recommends that a Department of the Army permit not be issued. The Service appreciates the opportunity to provide comments on this project. We would be pleased to meet with you, your staff, or the applicants to discuss our concerns. Sincerely, L.K.

Dear Mr. Wright: Thank you for your, letter of November 21, 1991 detailing the Corps concerns with the revised mitigation plan submitted for the Evans Road Extension project on October 28, 1991. Please find enclosed a revised (2nd revision) Wetlands/Flood Storage Mitigation Plan which we feel adequately addresses the concerns you noted. The revisions to the previously submitted Section 404 Permit Application are based upon our subsequent discussions with the Corps and a field review of the mitigation sites held on December 11, 1991 with the appropriate review agencies. In response to the specific concerns listed in your letter the following information has been included in the revised mitigation plan (attached) and is briefly explained here: a. Site 4 as depicted in the environmental assessment (refer to EA, Figure 4b) was proposed to be used only as necessary for bottomland hardwood wetlands mitigation should the acreage available in Sites 1A and 1B not be adequate to fully compensate for the wetland losses associated with the project. Site 4 as originally shown contained approximately 6-?- acres which were believed to be non-wetland. The revised (1st revision) mitigation plan indicated that 2.0 acres of Site 4 would be required for mitigation. This 2.0 acre site was shown as being contiguous to Site 1A. Site 4 as shown on Figure 4b of the Environmental Assessment/FONSI is a wooded area that extends northward of Site lA and is bounded by a cleared sewer line easement to the west and Lake Crabtree and its associated marsh type wetlands to the east. Agreement Page 2 April 3, 1992 Mr. Wright was reached at the December 11, 1991 field review as to the extent of the actual wetland areas in Site 4. It has been determined that 2.9-acres of suitable upland area is available within Site 4 for mitigation purposes. The 2.9 acres are contained in two areas and are identified on the attached Figure 1 as Site 4A and Site 4B. Sites 5 and 6 are required for flood storage mitigation and are proposed to be cleared and graded down an average of 2.5 feet. These two sites were offered as additional wetlands mitigation (marsh) beyond that proposed to offset the loss of bottomland hardwoods. b. The field review of Sites 1A and 1B (refer to Figure 4b, EA) determined that the acreage estimated on the aerial map to be available for mitigation purposes was larger than the actual, useable mitigation acreage. Site lA was reduced from 1.38 acres to `0.91 acres. Site 1B was found not to be suitable due to access limitations and has been removed as a proposed mitigation site. C. The revised mitigation plan will provide for the placement of 6" of hydric soil or other suitable topsoil taken from the area (to be disturbed by the project) within the wetlands creation sites. In addition, fertilizer or lime as determined necessary will be provided in these sites to enhance the survival of the planted seedlings. d. A 3 year monitoring plan for wetland hardwood creation has been accepted by NCDOT to include a success criteria of a minimum of 320 trees per acre living for 3 years without a height specification. The monitoring will continue until the success criteria is met, allowing provisions for replanting, regrading or other measures determined necessary to correct identified site problems. e. Species composition will not exceed 20 percent for any one tree species. Six species will be incorporated into tree plantings based upon seasonal or market availability. We currently propose to use tree species such as River birch (Betula nigra), Green ash (Fraxinus pennsylvanica), American Sycamore (Plantanus occidentalis L.), Overcup oak (Quercus lyrata), Swamp chestnut oak (Quercus michauxii), and Willow oak (Quercus phellos L.) to provide an acceptable diversity of plantings. After reviewing the mitigation sites in the field with COE representatives it was determined that additional mitigation acreage for the bottomland hardwood losses (which totaled 2.7 acres) were required beyond the 3.81 acres available at Sites 1A., 4A, and 4B. Page 3 April 3, 1992 Mr. Wright The applicants agreed to research and investigate other acceptable mitigation sites within the immediate project area to offer as additional mitigation. Field investigation of several nearby potential sites resulted in a new site just southwest of the project along Crabtree Creek which satisfies the COE requirements. Corps personnel reviewed the site in the field and found it acceptable provided adequate hydrology was available. Soil borings verified that an adequate hydrologic regime can be supported on this site with appropriate grading. Reforestation with selected hardwood species is proposed on the new site as previously proposed with Sites 1A, 4A and 4B. Additional detail concerning this new site labeled on Figure 2 as Site 8 is contained within the revised mitigation plan. The new Site 8 totals 2.66 acres and is contained within the 100 year floodplain of Crabtree Creek (owned by Wake County). A total of 6.47 acres of created hardwood wetlands is proposed with Sites 1A, 4A, 4B and 8 as identified. In addition, the mitigation for flood storage which occurs on Sites 2, 5, 6, and 7 will also provide for 4.78 acres of marsh wetlands through natural succession of nearby juncus and carex species. As previously noted a revised wetlands hardwood creation monitoring program has been accepted by NCDOT and is attached. If we can provide further assistance in expediting the Section 404 Permit please feel free to contact us. In the interest of time, we are providing the review agencies with a copy of all attached documentation. Thank you for your time and consideration. Sincerely, B ON, ADAMS, P & KING, INC.

Efforts were made to locate and identify the least environmentally damaging practicable alternative that met the state project purposes. Preliminary study lines were identified and wetland involvement determined for each. The alignment which had the least wetland involvement was chosen in order to avoid, to the maximum extent practicable, potential impacts. After determining that wetlands takings could not, totally be avoided with this project, steps were taken to minimize the adverse impacts as much as feasible. Project modifications included (1) reduction of right of way from 164 feet to 120 feet through the affected wetlands, (2) reduction of pavement lane widths from 12 feet to 11 feet to accommodate a reduced cross-section (3) elimination of the roadway median, (4) use of the steepest embankment slopes practical in this area (2:1), and (5) lowering of the proposed roadway grade to reduce width of embankment. Compensation for the unavoidable loss of 21k acres of wetlands is proposed through the restoration and creation of wetlands contiguous to and near this site. Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off-site wetlands and flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for hardwood wetlands losses within the same site. These sites, as shown on Figures 1 and 2 (attached) were chosen for their potential to both recover flood storage taken by the roadway embankment (approximately 1$.2 acre-feet) and remain in close proximity to the areas of wetland losses. Table 1 lists the specific sites designated for hardwood wetlands creation in priority with the estimated acres (wetlands) and acre-feet (flood storage) noted. Table 2 shows the additional sites of marsh type wetlands creation. These sites are listed as proposed mitigation areas. Actual acreages of wetlands impacted and cubic yards of roadway fill required within the flood storage basin will be determined in the final design phase. Coordination with the appropriate agencies for a Section 404 permit has been in progress for over one year and mutual agreement on sites and mitigation measures should be achieved with this plan. Wake County Board of Commissioners. on July 2, 1990 approved the use of lands within the 100-year floodplain (Wake County property) to mitigate flood storage and wetlands impacts associated with the Evans Road Extension project (refer to letter of August 22, 1990 from Wake County in Appendix C of State EA/FONSI). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, partially as a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surrounding terrain. A total loss of approximately 2.7 acres of bottomland hardwood wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 1 and 2. Site lA includes approximately 0.91 acres immediately adjacent to the north side of Crabtree Creek. Site 1A includes the levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating on Site 1A would provide an opportunity to restore bottomland forest similar to that proposed for clearing to accommodate the project. Grading 3.5 feet or more of the existing surface material would reduce the existing bank to match the surrounding bottomland contour, where saturated conditions generally prevail. After grading is complete, wetland tree species such as River birch (Betula pig a), Green ash (Fraxinus pennsylvanica), Overcup oak ( ueircus lyrata), and Swamp chestnut oak ( uercus michauxii), will be planted to compensate for forested wetland removed along the new causeway. The wetland reforestation shall be implemented as noted in the attached Project Special Provisions for Wetland Reforestation and Grading. Site 4A and 4B consists of 2.39 and 0.51 acres respectively just north of Site lA and also contains the Altavista soil discussed previously in connection with Site 1A. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species, as in Site 1A. The same tree species are proposed for planting on Site 4A and 4B. 2 TABLE 1 Proposed Wooded Wetlands/Flood Storage Mitigation Sites (Refer to Figures 1 and 2) Mitigation Wetlands Flood Storage Site Acres Acre-feet 1A 0.91 3.19 4A 2.39 9.56 4B 0.51 2.04 8 2.66 6.65 TOTAL 6.47 21.44 TABLE 2 Additional Flood Storage Mitigation Sites with Supplemental Marsh Wetlands Marsh Mitigation Wetlands Flood Storage Site - Acres Acre-feet 2 2.38 3.57 5 1.20 3.00 6 0.30 0.75 7 0.90 1.35 TOTAL 4.78 8.67 Site 8 is found approximately 2400 feet south (upstream) of the project corridor (refer to Figure 2). Site 8 totals 2.66 acres and is contained within the 100 year floodplain, owned by Wake County. This site was examined on January 24, 1992 by our biologist, Gary Blank, to determine whether the hydrology and soils present were conducive for wetland creation and if conducive, the extent of excavation required to insure successful mitigation. This site is mostly at or below the 100-year flood level (284.9 ft) but exhibits characteristics markedly different from the surrounding area. On a portion of the floodplain slightly higher and noticeably drier than immediately surrounding areas, this site is currently occupied by a mature loblolly pine stand. Adjacent floodplain areas to the south, north and west are dominated by bottomland hardwoods, with cane occurring in scattered lower lying places. Tree species occurring in these adjacent areas include Yellow-Poplar, River Birch, Green Ash, Willow Oak, and Sweetgum. To the 3? east, the site is bordered by a west facing slope and the mouth of a ravine formed by an intermittent drainage. In the pine stand itself, dead river birches (8-10 in. DBH) occur in several places, but most of the areas dominated by pine are now either pure pine or include scattered poplars and sweetgums. Eight test holes were dug at locations (Fig. 2) where vegetation indicators suggested that differing hydrological and soil characteristics might be observed (Table 3). Data gathered on the site and shown in Table 3 suggest that this site can be converted to a functioning wetland dominated by bottomland hardwood species, if proper measures are taken to assure success. The soils on the site are clearly alluvial in origin--either Chewacla or Congoree--a result of historical stream migration and associated sediment deposition. While the Wake County Soil Survey indicates Chewacla soils across much of the Crabtree floodplain, Congoree also occurs here and, based on field observations (Table 3), appears to be the more likely soil on this site. Adjacent to the proposed site on the north, however, an intermittent drain exhibits markedly different soil conditions more indicative of Wehadkee soil (Holes #1 and #8), with its darker gray color and increased saturation.

Holes #1 and #8 indicate the northern limit of the proposed mitigation site (Fig. 2). Similarly, Hole #4 indicates the western extent of the mitigation area, where the pine stand has given way to bottomland hardwoods, with soils beginning to exhibit hydric conditions. 4 The southern extent of the mitigation site corresponds to the limit of the pine stand, at about line stake 1-138 (Fig. 2). The site is fed by intermittent drains from relatively steep slopes to the east. As indicated by the hydrology observed in Holes #1, 4, 5, and 8, saturated conditions prevail in areas adjacent to the proposed mitigation site. The westernmost holes appear to reflect subsurface influence of Crabtree Creek and drainage from the ravine southeast of the site. The objective of this mitigation is to create hardwood wetland habitat on site currently dominated by mature pines, thereby mitigating loss of equivalent habitat in the proposed Evans Road corridor. Several points bear consideration in proposing site 8 and the following procedures. First, areas adjacent the pine stand are obviously exhibiting wetland characteristics, including development of hydric conditions in soils essentially the same as the soil beneath the pine stand. Second, the mature pines currently on the proposed site have effectively dried the soil through years of active transpiration. Removing these mature pine trees will have an immediate impact on the site's hydrology, reducing transpiration potential and thereby lengthening the hydroperiod following rainfall episodes. Third, the presence of dead River Birches of significant diameter suggests that at one time the proposed site was wetter than it is now and that stand composition may have been correspondingly different. Finally, it should be noted that the observations recorded in Table 3 were made during a time when winter rainfall had been markedly below levels typical of this region. In any case, current soil conditions must be altered by grading to reduce depth of subsoil material, thus the overall contour of the proposed site. Removing 3.0 feet of the existing material would reduce the site contour to a level below the surrounding bottomland contour, where saturated conditions generally prevail. In the removal process, surface humus and topsoil material would be retained for redistribution on the excavated site following removal of the lower soil layers. Replacement of 0.5 to 1.0 ft of topsoil and humus material would provide a hospitable medium for tree planting. After surface replenishment is complete, tree species such as River Birch (Betula ni a , Green Ash (Fraxinum pennUlvanica), American Sycamore (Elantanus occidentalis L.), Overcup Oak ( uercus lvrata), Swamp Chestnut Oak ( uercus michauxii), and Willow Oak ( uercus hellos L.) would be planted. Appropriate planting density and species composition will be as proposed previously with Site 1A, 4A and 4B. It is further proposed that to the extent possible, drainage from Weston's future upland development sites just east of this mitigation area be channeled into this area to augment naturally occurring drainage. Channeling stormflows in this manner will not only help irrigate the site but will also allow filtration of runoff from paved surfaces before stormflows enter the nearby Crabtree Creek and lake system. Appropriate monitoring of stand growth will be maintained by NCDOT, as indicated with the attached monitoring plan. Growth rates of bottomland hardwood plantations along Richland Creek on NCSU's Schenck Forest (part of the Crabtree Creek watershed) indicate 5 that under controlled conditions on a wet site, 1.0 ft. seedlings of the proposed species will reach average heights of 6.0 ft. three to five years after planting. On slightly drier adjacent areas of the same site, growth rates have been even better. Sites 2 and 7, located approximately 1,400 + feet northeast of the proposed ROW, includes 3.3 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface. Observation in May and June, hence during the growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline Juncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. Natural succession of juncus and carex species is expected on these sites. Sites 5 and 6 are wooded upland areas, between the sewerline easement and the lake, adjacent to sites 2 and 7 respectively. These sites would be graded down an average of 2.5 feet to further offset flood storage capacity loss and to offer supplemental wetlands mitigation with a similar scheme as noted for sites 2 and 7. As noted in Table 1 the total flood storage capacity recovered with sites 1A, 4A, 4B, and 8 is estimated at 21.44 acre-feet. Additional recovery will probably be needed depending upon final design calculations. Additional storage is proposed with sites 2, 5, 6 and 7 providing 8.67 acre-feet of flood storage as noted in Table 2 for the Crabtree system. The offering of marsh type wetlands on these sites totals 4.78 acres and is proposed only as supplemental wetlands mitigation. Permit Coordination In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolley (U.S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 404 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the current federal goal of no overall net loss of wetland values and functions. Monitoring Plan As part of the mitigation effort for this specific project a revised monitoring plan to insure that permit conditions are complied with has been developed by the N.C. Department of Transportation in coordination with the Corps of Engineers and is attached. In addition, Project Special Provisions for Wetland Reforestation and Grading to be used on this project are also attached. \90004.01\RevMitig.Pln Y DENOTES WETLANDS IA MITIGATION SITES OK -21' ?

The preparation of the wetlands mitigation sites associated with the project began in mid-spring 1993 with field surveys of each site. Calculation of the exact acreage of each site based on the survey data has revealed a shortfall of acreage available to mitigate wetlands losses as proposed in the "Wetlands/Flood Storage Mitigation Plan, Revision #3". The mitigation plan proposed four (4) sites totaling 6.47 acres of bottomland hardwood wetland mitigation to offset the taking of 2.7 acres of hardwood wetlands filled for the project. Table 1 indicates the acreage of each wetland mitigation site as proposed and the actual acreage surveyed. Figures 1 and 2 (attached) illustrate the general location of these sites. Mr. G. Wayne Wright \90004.01\WnghtM n Quality through teamwork 0 Mr. G.

Sites 2, 5, 6 and 7 have previously been described in the "Wetlands/Flood Storage Mitigation Plan, Revision #3". The conversion from flood storage to hardwood wetlands mitigation sites will not adversely affect the flood storage capacity required within the Lake Crabtree impoundment. Sites 2, 5, b and 7 total 4.08 (Table acres sites, a total of 8.42 acres of hardwood wetlands mitigation. Together with the original four mitigation will be prepared and 6.47 acres will be guaranteed survival as originally proposed in the approved permit and mitigation plan. Mr. G.

A minimum of 6" of topsoil, deeper (up to 18") in some areas will be provided on the sites. Corps of Engineers representatives as well as North Carolina Department of Transportation biologists and soil scientists have reviewed the proposed additional sites 2, 5, 6 and 7 in the field and have found the sites to be adequate for hardwood wetlands mitigation from a soils and hydrology perspective. Access to the sites 2, 5, 6 and 7 will be via the existing sewerline easement (shown on Figure 1). This sewerline easement is currently considered wetland (grassed) and access can be authorized for tem.^•oranl construction access under Nationwide Permit #33. The temporary construction access requires filling the sewerline easement to support access by heavy equipment and vehicles. The fill material for this temporary construction road will be removed in its entirety after construction is completed. The remedial restoration plan proposes the temporary construction access road be returned to its preconstruction elevation and all fill material removed to high ground. Natural succession will revegetate the easement area. Therefore, in accordance with the general and special conditions of the individual Section 404 permit for this project, the permittees hereby request a modification of the permit to reflect the described necessary changes in the mitigation plan and sites to compensate for the shortfall in acreage discovered during construction of the originally proposed bottomland hardwood mitigation sites.

Reference also.your letter of July 23, 1993, on behalf of the permittees, requesting modification of the permit to allow a change in the size and location of the mitigation sites, and to authorize, after-the-fact, a temporary construction access road. Specifically, you propose to change the nature of four previously proposed flood storage mitigation sites 2,5,6 and 7 on-the southeast side of Lake Crabtree to provide 4.08 acres of bottomland hardwood mitigation. This change would be to compensate for a 2.13 acre shortfall in the actual size of the _originally proposed hardwood mitigation sites, and to ensure survival requirements on a minimum of 6.47 acres, as originally required by the permit. The additional hardwood sites would be graded to elevation 276.5 and prepared and planted as required for the original sites. The existing temporary construction road on the sewerline easement is necessary for access to mitigation sites 2,5,6, and 7. All of the fill material for the road will be removed to high ground after construction is completed, and preconstruction elevations will be restored. The permit is hereby modified to authorize the mitigation plan changes and temporary access road described above, subject to the following additional condition: -2- The temporary road fill will be entirely removed to upland areas following completion of the construction activity, and the affected areas restored to pre-project conditions.

Although I will defer to the NCDOT opinion that the road is necessary to insure adequate traffic flow .I question the wisdom of constructing.this road in light of the following statement included in your response. "Even by adding the multi-lane section of Evans Road Extension and widening NC54 and North Harrison Avenue we find only a marginal improvement in level-o€-service for NC 54 and North Harrison Avenue." It would appear prudent to investigate alternate methods of transportation if the roads being constructed will only marginally improve the level of service. 2.

Colonel Suermann: May 15, 1991 Ste. _j 7,1 MAY 21 1991 ; u QUALITY SECTION This responds to a May 2, 1991 letter from Dr. Wayne Wright requesting the U. S. Fish and Wildlife Service's (Service) review and comment on supplemental information pertaining to the Public Notice for Action ID 199100143, dated December 13, 1990. The applicant, North Hills Properties, Inc., proposes to place fill material in 2.64 acres of forested wetlands adjacent to Crabtree Creek to construct a four-lane public highway as part of the extension to Evans Road in Cary, Wake County, North Carolina. Supplemental information about the project was provided in letters dated January 23, 1991 and April 10, 1991 from Ronald G. Hairr of BAKK Engineers, and project concerns were discussed at a coordination meeting in Raleigh on May 8, 1991. This is the report of the Service and the Department of the Interior and supplements our previous report dated January 25, 1991. It is submitted in accordance with 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. 1533-1545) (Act). It is to be used in your determination of 404(b)(1) compliance (40 CFR 230) and your public interest review (33 CFR 320.4) as they relate to the protection of fish and wildlife resources. The supplemental information provided cited projected traffic volumes in the year 2010 for Evans Road, NC 54 and SR 1652 as justification that alternative routing and improvements to existing roadways would not provide an adequate level of service. The Service continues to believe the public interest would best be served by impact avoidance. only minimal gains in improved traffic flow would be temporarily achieved through construction of this section of roadway. We concur with the finding that the proposed project is unlikely to adversely impact the Federally-listed endangered red-cockaded woodpecker (Picoides borealis) based on the lack of suitable habitat in the area. Therefore, the requirements of Section 7(c) of the Endangered Species Act are fulfilled. However, obligations under Section 7 of the Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered; (2) this action is subsequently modified in a manner which was not considered in this review; or (3) a new species is listed or critical habitat determined that may be affected by the identified action. If the Corps determines that no reasonable and practical alternatives exist and the remaining impacts are thus unavoidable, the Service's remaining concerns are in regard to the mitigation plan. This plan is described in the State Environmental Assessment / Finding of No Significant Impact for the project, dated September 18, 1991, and in the revised mitigation site %. monitoring guidelines included as an attachment to the above referenced letter of April 10, 1991. The mitigation plan, as currently proposed, involves restoration of 1.97 acres of bottomland hardwood forest and creation of 4.78 acres of freshwater marsh. Total mitigation acres are based on the need to offset flood storage capacity losses occurring from project construction. An additional area of up to 6.0 acres of upland hardwood is proposed to be used only as needed to mitigate flood storage capacity losses. The Service believes this plan is not adequate to replace in-kind the lost forested wetland habitat values. Minimum mitigation acreage should not be limited to that which is necessary to compensate for flood storage capacity. It should be adequate to assure replacement of habitat value lost. Recent. research by Dr. Gerald McRain has shown that, for bottomland hardwood forested wetlands in North Carolina, a 3:1 ratio of replacement habitat to habitat lost is generally adequate for assuring no net habitat value loss. More specifically, the proposed 20-foot planting spacing and 30 percent acceptable survival rate are unacceptable because they will not replace the habitat value lost. The Service recommends that the spacing be reduced, thereby increasing planting density, and/or the acceptable level of survival be increased, so that the expected result will be a mature forest with 520- foot spacing of the desired species. Reasonably accurate estimates of survival rate should be a required part of the mitigation plan. Further, we recommend annual monitoring of the mitigation site for effectiveness be done annually for the first two years following completion of planting with a follow-up inspection after the fifth growing season. If replanting is required, additional monitoring will be necessary. The Service approves of the four species proposed for planting but would like a list of alternative species which will be used if the preferred species are not available at the time of planting. Because the proposed mitigation sites are not on property owned by the applicant, a written agreement signed by the property owner (Wake County)-that allows for the initial grading and planting, monitoring, and possible replanting should be included in the final mitigation plan. In order to effect fish and wildlife resource conservation and to fulfill the public trust in this matter, the Service continues to recommend that a Department of the Army permit not be issued for the proposed project until the above issues are resolved. The Service appreciates the opportunity to provide these comments. We would be pleased to meet with you, your staff, or the applicant to discuss our concerns. Sincerely yours, Go?x L.K.

Your suggestion that we provide additional information to address these comments was welcomed. We are pleased to provide the following information for each of the primary objections and/or comments from the responding agencies. Each comment is stated below with response. US Fish and Wildlife Service - Letter of January 25, 1991. Comment: (page 2, paragraph 3) "Performance criteria are not specified in the Public Notice." Response: Performance criteria as noted here relates to the acceptable survival rate of wetland species planted within the mitigation areas. The original mitigation proposal did not specify the percentage considered acceptable. North Carolina Department of Transportation (NCDOT) has reviewed this matter and now proposes a 30% population planted and natural succession as the acceptable survival rate. The revised Wetland Monitoring Program for this project is attached to this letter for submittal to the US Army Corps of Engineers. Comment: (page 3, paragraph 3) "The Federally - listed endangered red-cockaded woodpecker (Picoides borealis) may occur within the impact area of the proposed project. If the proposed project will be removing pines greater than or equal to 30 years of age in pine or pine/hardwood habitats, surveys should be conducted for active cavity trees within a '/2-mile radius of project boundaries. If red-cockaded woodpeckers are observed within the project area or active cavity trees found, the project has the potential to adversely affect the red-cockaded woodpecker,..." Response: Based upon several field surveys by a qualified biologist no evidence was found to suggest inhabitation by any wildlife species listed as threatened or endangered in North Carolina. Specifically, no nesting habitat for the red-cockaded woodpecker exists in the project area, nor were any red-cockaded woodpeckers observed during the field surveys. Comment: (page 3, paragraph 4) "Several upland alternatives to the proposed project appear available. Alternative routing via Weston Parkway, NC 54 and Aviation Parkway, much of it presently four-laned, is already in place." Response: No upland alternatives to the proposed Evans Road corridor have been. identified and none appear feasible. The thoroughfare planning studies conducted by NCDOT identified the need for a new highway corridor (Evans Road) as the best means to serve north-south travel in the area. To omit this short section of Evans Road between Weston Parkway and Aviation Parkway would defeat the purpose of the Evans Road corridor, which is to serve nort h-south travel and relieve the overloaded NC 54 through Morrisville. The Evans Road corridor as planned is a major element in the approved Greater Raleigh Urban Area Thoroughfare Plan_ eventually providing a multilane facility from downtown Cary out to I-40 and the . planned Northern Wake Expressway where it would have access via an interchange. Alternative routing via sections of Weston Parkway, NC 54 and Aviation Parkway is not an acceptable method of handling the future traffic demands in this area. Capacity analyses of NC 54, North Harrison Avenue and Evans Road indicates multi-lane facilities ,will be required for NC 54 and North Harrison Avenue by the design year (2010) even with the Evans Road corridor in place. Rerouting the traffic demand to the existing roadways will only worsen these congested highways and further deteriorate traffic operations. Comment: (page 3, paragraph 4) "Further, upland habitats adjacent to the wetlands may be developed through access from existing Weston Parkway and Aviation Parkway without the need for the proposed wetland crossing and fill activities. " Response: The purpose of this highway project, which was approved and programmed by the North Carolina Board of Transportation in their latest Transportation Improvement Program, is to provide for an integral link in an approved transportation corridor that was determined to be necessary and in the public interest to correct an inadequacy of north-south connectors in the rapidly growing Cary area. This project has never been identified nor intended to provide access to allow for property development. It will, as noted in the approved Environmental Assessment/Finding of No Significant Impact, allow for improved traffic access to nearby highways and freeways for a large, developing area, and thus provide improved traffic operations for the entire area. Comment: (page 3, paragraph 4) "...based on our site visit, much of the area proposed for use as mitigation is already comprised of functional wetlands." Response: The determination of suitable wetland mitigation sites was made by our biologist during the spring of 1990. Observation in May and June 1990 during the growing season confirmed dry conditions and no wetland species on these sites. On September 6, 1990 a pre-application field review with representatives of the Corps of Engineers confirmed the wetlands delineation for the project and potential mitigation sites. We maintain that the mitigation sites proposed are not currently functional wetlands and will provide excellent opportunity to restore and/or create- habitat to replace that impacted. US Environmental Protection Agency - Letter of January 14, 1991. Comment: (page 1, paragraph 3) "It is our understanding that the applicant has upland alternative for road alignment that could- be easily utilized instead of locating the work in wetlands." Response: The concern here is identical to a previous one expressed by the US Fish and Wildlife Service in their letter of January 25, 1991 and already addressed. NC Department of Environment, Health and Natural Resources, Division of Environmental Management - Letter of January 31, 1991. Comment: (page 1, paragraph 2) "Please submit a detailed alternatives analysis outlining why the existing roads and interchange cannot be further upgraded to accommodate the projected traffic demand. Specifically, can the Harrington (Harrison) Avenue interchange be upgraded to accommodate the projected increase of 3,900 vehicles per day by 2010? Do the traffic projections take into account the recent and future improvements to I-40? Also, please include the basis for the projected traffic demand." Response: The basis for the projected traffic demand is data collected and prepared by the North Carolina Department of Transportation through their Statewide Planning and Research Units. Traffic counts are taken on various highways and entered into computer models along with data on population growth rates, economic activity, planned highway improvements and historic traffic patterns. Traffic projections for roadways within this project study area were prepared by taking this data and forecasting future demands along I-40, Harrison Avenue, NC 54 and other roads in the vicinity. These traffic numbers are further refined by traffic analysts in the Research Unit to reflect existing and/or planned improvements or other factors which may not have been previously taken into account. The traffic projections approved for use by NCDOT are shown on Figures 2a -and 2b of the approved EA/FONSI for the project. The traffic projections made for the Evans Road project do take into account the recent six-lane widening of I-40 and the planned improvement of I-40 to eight lanes. The projected increase in traffic for the Harrison Avenue interchange is not 3900 vehicles per day by 2010 as stated in the comment. The correct increase is projected to be 14,800 vehicles per day. The 3,900 vpd figure was apparently derived from the difference between the 2010 projections for the road network comparing the traffic with and without the Evans Road Extension. Upgrading the existing roads (NC 54 and North Harrison Avenue) and the interchange to accommodate the projected traffic demand will not by itself adequately address the future traffic needs in the study area. Capacity analyses were performed to evaluate the existing road network to see if it could handle the future traffic. The analyses showed that the existing lanes without. improvements would suffer breakdown conditions (level-of-service F). Widening NC 54, North- Harrison Avenue to four and five lane sections respectively, also results. in levels-of-service E and F. These levels of service for arterial facilities are considered unacceptable for adequate traffic operations. The capacity analyses work sheets supporting these findings were previously supplied to the Corps on January 23, 1991 in response to an earlier request. Even by adding the multi-lane section of Evans Road Extension and widening NC 54 and North Harrison Avenue we find only a marginal improvement in level-of- service for NC 54 and North Harrison Avenue. It is our opinion that six lanes will ultimately be required on NC 54 and North Harrison. Avenue as well as major improvements to the North Harrison Avenue interchange with I-40 in order to achieve the desirable levels-of-service (LOS C or D) for this network. The basic premise found in this analysis is that the rapid growth of the Cary area, specifically the north Cary area, over the next 10 to 20 years is demanding additional infrastructure be supplied to handle this increase in population and business activity. Simply widening the existing two roads which provide north-south travel in the north Cary area will not be sufficient to satisfy the traffic demands at acceptable levels. Comment: (page 1, paragraph 3) "An evaluation of the mitigation plan is not possible at this time due to insufficient information." Response: A summary of the mitigation measures offered is contained within the approved EA/FONSI document for this project. Additional information concerning the mitigation measures were provided to the Corps of Engineers in the Section 404 permit application, including a monitoring plan developed by NCDOT. The mitigation and monitoring plans were reviewed in light of this comment and additional detail has been prepared and is hereby submitted to the Corps. NCDOT continues to feel that a two (2) year monitoring program is adequate. Other recent permits in more sensitive wetland areas have been acquired utilizing the two (2) year monitoring plan. Additional detail on size, height and plant spacing is provided in the attached Wetland Monitoring Program. An acceptable survival rate of 30% population planted and natural succession is proposed. In addition, a planting schedule and landscape design plans are being prepared by the Roadside Environmental Unit of NCDOT and will be included within the final design plans.

On February 28, you advised _BAKK of objections that your office-had- received for issuing this permit. This project is a joint venture between the Department of Transportation and North Hills, Inc. and Silverton, Inc. with the cost of the project being shared equally. BAKK.is handling the planning, design, and construction of this project on behalf of North Hills and Silverton. The Department fully supports this project and feels it will provide a vital transporation link for this rapidly growing area upon completion. Before the Department enters into a public/ private agreement of this nature, we first determine that the anticipated benefits of the project actually exceed the benefits from a regular Tranportation Improvement Project. The Department also reviewed other viable alternatives to the project such as different alignments 'and/or improving existing roads. This project, with its currently designed location, met all the criteria for Department funding and anticipated transportation needs in the project area. This project is also included in the Town of Cary's Thoroughfare Plan. An Equal Opportunity/Affirmative Action Employer -2- I hope your office will review the permit application submitted by BAKK and the appropriate permits be issued as quickly as possible so this project can be constructed as scheduled.

I have reviewed the material and offer the following comments: 1. Although I will defer to the NCDOT opinion that the road is necessary to insure adequate traffic flow I question the wisdom of constructing this road in light of the following statement included in your response. "Even by adding the multi-lane section of Evans Road Extension and widening NC54 and North Harrison Avenue we find only a marginal improvement in level-of-service for NC 54 and North Harrison Avenue." It would appear prudent to investigate alternate methods of transportation if the roads being constructed will only marginally improve the level of service. 2. The modified mitigation plan is not acceptable. The density of trees to be planted and the monitoring plan are not adequate. It is recommended that a meeting be scheduled with all of the agencies involved with this project to discuss what constitutes an acceptable mitigation proposal. roUuUon hewm8on rays P.O.

WAKE COUNTY, NORTH CAROLINA. The following description of the work is taken from data provided by the applicant and from observations made during an onsite visit by representatives of the U.S. Army Corps of Engineers. Plans submitted with the application show the placement of approximately 41,900 cubic yards of clean fill material into wetlands adjacent to Crabtree Creek, at the upper end of Lake Crabtree, for construction of approximately 1,500 feet of a four-lane public highway. The new highway would extend the existing Evans Road approximately 3,500 feet to the northwest from where it currently ends at Weston Parkway (S.R. 1653), across Crabtree Creek to Aviation Parkway (S.R. 1002). The proposed highway embankment would be an average of approximately 95 feet wide, bottom width (maximum 118 feet) where it crosses the wetlands, requiring the loss of approximately 2.64 acres of bottomland hardwood wetlands. The embankment would include a 3 feet wide extension for a proposed Wake County greenways trail which would connect to other proposed trails on the upland. The embankment would also include four culverts: one 24-inch, two 30-inch and one 66-inch. Approximately 95 cubic yards of clean earth fill would be placed below ordinary high water to relocate a tributary to Crabtree Creek, and stone riprap would be placed within Crabtree Creek to facilitate a bridge crossing. To compensate for the proposed wetlands loss, the applicant proposes to restore and create a total of approximately 6.7 to 12.7 acres of wetlands. The final acreage of compensation area would depend on final design calculations of flood storage capacity and and the further excavation needed to mitigate the storage capacity deficit. The applicant proposes to grade, and plant with wetland plant species, as appropriate, seven areas contiguous with Crabtree Creek's adjacent wetlands. The compensation sites would be monitored for viability for a minimum period of 2 years following planting. Plans for the proposed construction are included with this public.notice. The State of North Carolina will review this public notice to determine the need for the applicant to obtain any required State authorization. No DA permit will be issued until the coordinated State viewpoint on the proposal has been received and reviewed by this agency, nor will a DA permit be issued until the North Carolina Division of Environmental Management (DEM) has determined the applicability of a Water Quality Certificate as required by PL 92-500. -A -2- This application is being considered pursuant to Section 404(b) of the Clean Water Act (33 U.S.C. 1344). Any person may request, in writing within the comment period specified in the notice, that a public hearing be held to consider this application. 'Requests for public hearing shall state, with particularity, the reasons for holding a public hearing. The District Engineer has consulted the latest published version of the National Register of Historic Places for the presence or absence of registered properties, or properties listed as being eligible for inclusion therein, and this worksite is not registered property or property listed as being eligible for inclusion in the Register. Consultation of the National Register constitutes the extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or historical data may be lost or destroyed by work under the requested permit. The District Engineer has determined, based on a review of data furnished by the applicant and onsite observations, that the activity will not affect species, or their critical habitat, designated as endangered or threatened pursuant to the Endangered Species Act of 1973. The decision whether to issue a permit will be based on an evaluation of the probable impacts, including cumulative impacts, of the proposed activity and its intended use on the public interest: Evaluation of the probable impacts which the proposed activity may have on the public interest requires a careful weighing of all those factors which become relevant in each particular case. The benefits which reasonably may be expected to accrue from the proposal must be balanced against its reasonably foreseeable.detriments. The decision whether to authorize a proposal, and if so the conditions under which it will be allowed to occur, are therefore determined by the outcome of the general balancing process. That decision should reflect the national concern for both protection and utilization of important resources. All factors which may be relevant to the proposal must be considered including the cumulative effects thereof. Among those are conservation, economics, aesthetics, general environmental concerns, wetlands, cultural values, fish and wildlife values, flood hazards, flood plain values, land use, navigation, shore erosion and accretion, recreation, water supply and conservation, water quality, energy needs, safety, food and fiber production, mineral needs, considerations of property ownership, and, in general; the needs and welfare of the people. For activities involving the placement of dredged or fill materials in waters of the United States, a permit will be denied if the discharge that would be authorized by such permit would not comply with the Environmental Protection Agencies' 404(b)(1) guidelines. Subject to the preceding sentence and any othet applicable guidelines or criteria, a permit will be granted unless the District Engineer determines that it would be contrary to the public interest. -3- The Corps of Engineers is soliciting comments from the public; Federal, State, and local agencies and officials; Indian Tribes, and other interested parties in order to consider and evaluate the impacts of this proposed activity. Any comments received will be considered by the Corps of Engineers to determine whether to issue, modify, condition, or deny a permit for this proposal. To make this decision, comments are used to assess impacts on endangered species, historic properties, water quality, general environmental effects, and the other public interest factors listed above. Comments are used in preparation of an Environmental Assessment and/or Environmental Impact Statement pursuant to the National Environmental Policy Act. Comments are also used to determine the need for a public hearing and to determine the overall public interest of the proposed activity. Generally, the decision whether to issue this DA permit will not be made until the DEM issues, denies, or waives State certification required by Section 401 of the Clean Water Act. The DEM considers whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the Clean Water Act. The application and this. public notice for the DA permit serves as application to the DEM. for certification. Additional information regarding the Clean Water Act certification may be reviewed at the offices of the Environmental Operations Section, North Carolina Division of Environmental Management, Salisbury Street, Archdale Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person requesting copies upon payment of reproduction costs. The North Carolina Division of Environmental Management plans to take final action in the issuance of the Clean Water Act certification on or after January 7, 1991. All persons desiring to make comments regarding the application for Clean Water Act certification should do so in writing delivered to the North Carolina Division of Environmental Management, Post Office Box 27687, Raleigh, North Carolina 27611-7687, on or before December 31, 1990, Attention: Mr. William Mills. Written comments pertinent to the proposed work, as outlined above, will be received in this office, Attention: Mr. Eric Alsmeyer, until 4:15 p.m., January 14, 1991, or telephone (919) 846-0749. go- iSITE man R Ef p Bill "SITE A 7 .AM .

Proposed Evans Road Extension NCDOT Project U-2403 Wake County Thank you for responding to my letter of January 31, 1991 requesting additional information concerning the subject request. I have reviewed the material and offer the following comments: 1. Although I will defer to the NCDOT opinion that the road is necessary to-insure adequate traffic flow I question the wisdom of constructing this road in light of the following statement included in your response. "Even by adding the multi-lane section of Evans Road Extension and widening NC54 and North Harrison Avenue we find only a marginal improvement in level-of-service for NC 54 and North Harrison Avenue." It would appear prudent to investigate alternate methods of transportation if the roads being constructed will only marginally improve the level of service. 2. The modified mitigation plan is not acceptable. The density of trees to be planted and the monitoring plan are not adequate. It is recommended that a meeting be scheduled with all of the agencies involved with this project to discuss what constitutes an acceptable mitigation proposal. Poeudon Pm%"W on rays P.O. Box 27687.

Your suggestion that we provide additional information to address these comments was welcomed. We are pleased to provide the following information for each of the primary objections and/or comments from the responding agencies. Each comment is stated below with response. US Fish and Wildlife Service - Letter of January 25, 1991. Comment: (page 2, paragraph 3) "Performance criteria are not specified in the Public Notice." Response: Performance criteria as noted here relates to the acceptable survival rate of wetland species planted within the mitigation areas. The original mitigation proposal did not specify the percentage considered acceptable. North Carolina Department of Transportation (NCDOT) has reviewed this matter and now proposes a 30% population planted and natural succession as the acceptable survival rate. The revised Wetland Monitoring Program for this project is attached to this letter for submittal to the US Army Corps of Engineers. Comment: (page 3, paragraph 3) "The Federally - listed endangered red-cockaded woodpecker (Picoides borealis) may occur within the impact area of the proposed project. If the proposed project will be removing pines greater than or equal to 30 years of age in pine or pine/hardwood habitats, surveys should be conducted for active cavity trees within a 1/2-mile radius of project boundaries. If red-cockaded woodpeckers are observed within the project area or active cavity trees found, the project has the potential to adversely affect the red-cockaded woodpecker,..." Response: Based upon several field surveys by a qualified biologist no evidence was found to suggest inhabitation by any wildlife species listed as threatened or endangered in North Carolina. Specifically, no nesting habitat for the red-cockaded woodpecker exists in the project area, nor were any red-cockaded woodpeckers observed during the field surveys. Comment: (page 3, paragraph 4) "Several upland alternatives to the proposed project appear available. Alternative routing via Weston Parkway, NC 54 and Aviation Parkway, much of it presently four-laned, is already in place." Response: No upland alternatives to the proposed Evans Road corridor have been identified and none appear feasible. The thoroughfare planning studies conducted by NCDOT identified the need for a new highway corridor (Evans Road) as the best means to serve north-south travel in the area. To omit this short section of Evans Road between Weston Parkway and Aviation Parkway would defeat the purpose of the Evans Road corridor, which is to serve north-south travel and relieve the overloaded NC 54 through Morrisville. The Evans Road corridor as planned is a major element in the approved Greater Raleigh Urban Area Thoroughfare Plan eventually providing a multilane facility from downtown Cary out to I-40 and the planned Northern Wake Expressway where it would have access via an interchange. Alternative routing via sections of Weston Parkway, NC 54 and Aviation Parkway is not an acceptable method of handling the future traffic demands in this area. Capacity analyses of NC 54, North Harrison Avenue and Evans Road indicates multi-lane facilities will be required for NC 54 and North Harrison Avenue by the design year (2010) even with the Evans Road corridor in place. Rerouting the traffic demand to the existing roadways will only worsen these congested highways and further deteriorate traffic operations. Comment: (page 3, paragraph 4) "Further, upland habitats adjacent to the wetlands may be developed through access from existing Weston Parkway and Aviation Parkway without the need for the proposed wetland crossing and fill activities. " Response: The purpose of this highway project, which was approved and programmed by the North Carolina Board of Transportation in their latest Transportation Improvement Program, is to provide for an integral link in an approved transportation corridor that was determined to be necessary and in the public interest to correct an inadequacy of north-south connectors in the rapidly growing Cary area. This project has never been identified nor intended to provide access to allow for property development. It will, as noted in the approved Environmental Assessment/Finding of No Significant Impact, allow for improved traffic access to nearby highways and freeways for a large, developing area, and thus provide improved traffic operations for the entire area. Comment: (page 3, paragraph 4) "...based on our site visit, much of the area proposed for use as mitigation is already comprised of functional wetlands." Response: The determination of suitable wetland mitigation sites was made by our biologist during the spring of 1990. Observation in May and June 1990 during the growing season confirmed dry conditions and no wetland species on these sites. On September 6, 1990 a pre-application field review with representatives of the Corps of Engineers confirmed the wetlands delineation for the project and potential mitigation sites. We maintain that the mitigation sites proposed are not currently functional wetlands and will provide excellent opportunity to restore and/or create habitat to replace that impacted. US Environmental Protection Agency - Letter of January 14, 1991. Comment: (page 1, paragraph 3) "It is our understanding that the applicant has upland alternative for road alignment that could be easily utilized instead of locating the work in wetlands." Response: The concern here is identical to a previous one expressed by the US Fish and Wildlife Service in their letter of January 25, 1991 and already addressed. NC Department of Environment, Health and Natural Resources, Division of Environmental Management - Letter of January 31, 1991. Comment: (page 1, paragraph 2) "Please submit a detailed alternatives analysis outlining why the existing roads and interchange cannot be further upgraded to accommodate the projected traffic demand. Specifically, can the Harrington (Harrison) Avenue interchange be upgraded to accommodate the projected increase of 3,900 vehicles per day by 2010? Do the traffic projections take into account the recent and future improvements to I-40? Also, please include the basis for the projected traffic demand." Response: The basis for the projected traffic demand is data collected and prepared by the North Carolina Department of Transportation through their Statewide Planning and Research Units. Traffic counts are taken on various highways and entered into computer models along with data on population growth rates, economic activity, planned highway improvements and historic traffic patterns. Traffic projections for roadways within this project study area were prepared by taking this data and forecasting future demands along I-40, Harrison Avenue, NC 54 and other roads in the vicinity. These traffic numbers are further refined by traffic analysts in the Research Unit to reflect existing and/or planned improvements or other factors which may not have been previously taken into account. The traffic projections approved for use by NCDOT are shown on Figures 2a and 2b of the approved EA/FONSI for the project. The traffic projections made for the Evans Road project do take into account the recent six-lane widening of I-40 and the planned improvement of I-40 to eight lanes. The projected increase in traffic for the Harrison Avenue interchange is not 3900 vehicles per day by 2010 as stated in the comment. The correct increase is projected to be 14,800 vehicles per day. The 3,900 vpd figure was apparently derived from the difference between the 2010 projections for the road network comparing the traffic with and without the Evans Road Extension. Upgrading the existing roads (NC 54 and North Harrison Avenue) and the interchange to accommodate the projected traffic demand will not by itself adequately address the future traffic needs in the study area. Capacity analyses were performed to evaluate the existing road network to see if it could handle the future traffic. The analyses showed that the existing lanes without improvements would suffer breakdown conditions (level-of-service F). Widening NC 54, North Harrison Avenue to four and five lane sections respectively, also results in levels-of-service E and F. These levels of service for arterial facilities are considered unacceptable for adequate traffic operations. The capacity analyses work sheets supporting these findings were previously supplied to the Corps on January 23, 1991 in response to an earlier request. Even by adding the multi-lane section of Evans Road Extension and widening NC 54 and North Harrison Avenue we find only a marginal improvement in level-of- service for NC 54 and North Harrison Avenue. It is our opinion that six lanes will ultimately be required on NC 54 and North Harrison Avenue as well as major improvements to the North Harrison Avenue interchange with I-40 in order to achieve the desirable levels-of-service (LOS C or D) for this network. The basic premise found in this analysis is that the rapid growth of the Cary area, specifically the north Cary area, over the next 10 to 20 years is demanding additional infrastructure be supplied to handle this increase in population and business activity. Simply widening the existing two roads which provide north-south travel in the north Cary area will not be sufficient to satisfy the traffic demands at acceptable levels. Comment: (page 1, paragraph 3) "An evaluation of the mitigation plan is not possible at this time due to insufficient information." Response: A summary of the mitigation measures offered is contained within the approved EA/FONSI document for this project. Additional information concerning the mitigation measures were provided to the Corps of Engineers in the Section 404 permit application, including a monitoring plan developed by NCDOT. The mitigation and monitoring plans were reviewed in light of this comment and additional detail has been prepared and is hereby submitted to the Corps. NCDOT continues to feel that a two (2) year monitoring program is adequate. Other recent permits in more sensitive wetland areas have been acquired utilizing the two (2) year monitoring plan. Additional detail on size, height and plant spacing is provided in the attached Wetland Monitoring Program. An acceptable survival rate of 30% population planted and natural succession is proposed. In addition, a planting schedule and landscape design plans are being prepared by the Roadside Environmental Unit of NCDOT and will be included within the final design plans. Please find attached a copy of the revised Wetland Monitoring Program prepared by NCDOT. If additional information is needed for your review please feel free to contact us at your convenience.

STATE HIGHWAY ADMINISTRATOR RE: Proposed Evans Road Extension over Crabtree Creek in Cary - NCDOT Project U-2403; Action ID # 199100143 Dear Cliff: On November 20, 1990, BAKK Engineers applied for a permit from your office for the above captioned project in Wake County. On February 28, you advised BAKK of objections that your office had received for issuing this permit. This project is a joint venture between the Department of Transportation and North Hills, Inc. and Silverton, Inc. with the cost of the project being shared equally. BAKK is handling the planning, design, and construction of this project on behalf of North Hills and Silverton. The Department fully supports this project and feels it will provide a vital transporation link for this rapidly growing area upon completion. Before the Department enters into a public/ private agreement of this nature, we first determine that the anticipated benefits of the project actually exceed the benefits from a regular Tranportation Improvement Project. The Department also reviewed other viable alternatives to the project such as different alignments and/or improving existing roads. This project, with its currently designed location, met all the criteria for Department funding and anticipated transportation needs in the project area. This project is also included in the Town of Cary's Thoroughfare Plan. An Equal Opportunity/Affirmative Action Employer -2- I hope your office will review the permit application submitted by BAKK and the appropriate permits be issued as quickly as possible so this project can be constructed as scheduled.

The wetlands to be impacted by,this project are a significant natural` resource and should be protected unless there is no practicable alternative to the proposed project. Please submit a detailed alternatives analysis outlining why the existing roads and interchange cannot be further upgraded to accommodate the projected traffic demand. Specifically, can the Harrington Avenue interchange be upgraded to accommodate the projected increase of 3900 vehicles per day by 2010? Do the traffic projections take into account the recent and future improvements to I-40? Also, please include the basis for the projected traffic demand. An evaluation of the mitigation plan is not possible at this time due to insufficient information. It is recommended that you consult MIST - Mitigation Site Type Classification (EPA - Region IV Wetland Planning Unit, Atlanta, GA.) when preparing mitigation proposals.

Efforts were made to locate and identify the least environmentally damaging practicable alternative that met the state project purposes. Preliminary study lines were identified and wetland involvement determined for each. The alignment which had the least wetland involvement was chosen in order to avoid, to the maximum extent practicable, potential impacts. After determining that wetlands takings could not totally be avoided with this project, steps were taken to minimize the adverse impacts as much as feasible. Project modifications included (1) reduction of right of way from 164 feet to 120 feet through the affected wetlands, (2) reduction of pavement lane widths from 12 feet to 11 feet to accommodate a reduced cross-section (3) elimination of the roadway median, (4) use of the steepest embankment slopes practical in this area (2:1), and (5) lowering of the proposed roadway grade to reduce width of embankment. Compensation for the unavoidable loss of 2.7 acres of wetlands is proposed through the restoration and creation of wetlands contiguous to this site. Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off-site wetlands and flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for wetlands losses within the same site. These sites, as shown on Figures 4a and 4b, (of the State EA/FONSI) were chosen for their potential to both recover flood storage taken by the roadway embankment and remain in close proximity to the areas of wetland losses. Table 1 lists the specific sites in priority with the estimated acres (wetlands) and acre-feet (flood storage) noted. These sites are listed as potential mitigation areas. Actual acreages of wetlands impacted and cubic yards of roadway fill required within the flood storage basin will be determined in the final design phase. Coordination with the appropriate agencies for a Section 404 permit will be completed prior to agreement on specific sites and mitigation measures for this project. Approval to use lands within the 100-year floodplain (Wake County property) to mitigate flood storage and wetlands impacts has been advanced by the Wake County Board of Commissioners on July 2, 1990 .(refer to letter of August 22, 1990 from Wake County in Appendix C of State EAXONSI). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surrounding terrain. A total loss of approximately 2.7 acres of wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 4a and 4b. Sites IA and 1B include approximately 2.0 acres immediately adjacent both sides of Crabtree Creek. Site ILA includes the western levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Area 1B includes the levees of Congoree soil on the east bank between the creek channel and slackwater sloughs or tributary stream channels entering Crabtree Creek. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating here (Sites 1A and 1B ) would provide an opportunity to restore bottomland forest similar to that proposed for clearing to accommodate the project. Grading 3.5 feet or more of the existing surface material would reduce existing banks to match the surrounding bottomland contour, where saturated conditions generally prevail. After grading is complete, wetland tree species such as River birch (Betula ni ra , Green ash Fraxinus pennsylvanica), Overcup oak uercus I to , and Swamp chestnut oak uercus michauxii), should be planted to compensate for forested wetland removed along the new causeway. Sites 2 and 7, located approximately 1,400 + feet northeast of the proposed ROW, includes 33 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface. Observation in May and June, hence during the current growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline uncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. Due to the distance from the project and its small size, Site 3, (not shown) consisting of 0.2 acres has been rejected as a feasible mitigation site. Site 4, contiguous with Site IA, also contains the Altavista soil discussed previously in connection with Site IA. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species, as in Site 1A. The same species of oaks and river birch are proposed for planting here as required.

These sites could be graded down an average of 2.5 feet to further offset flood storage capacity loss and mitigate wetlands with a similar scheme as noted for sites 2 and 7. As noted in Table 1 the total flood storage capacity recovered with sites IA, 1B, 29 5, 6, and 7 is estimated at 15.6 acre-feet. Additional recovery may or may not be needed to achieve the 18.2 acre-feet depending upon final design calculations.` Should additional storage be required, Site 4 is proposed to be used only as needed to mitigate the remaining flood storage capacity deficit. Permit Coordination In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolly (U.S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 404 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the cdrrent federal goal of no overall net loss of wetland values and functions. Monitoring Plan As part of the mitigation effort for this specific project a monitoring plan to insure that permit conditions are complied with has been developed by the N.C. Department of Transportation in coordination with the Corps of Engineers and is attached. PROJECT 9.8050364 U-2403 GUIDELINES FOR WETLAND MONITORING PROGRAM I.

Stevens Wake County Manager P. O. Box 550 Raleigh, North Carolina 27602 NCDOT PROJECT U-2403 Sheet _Z of Z NOV, 1990 POTENTIAL WETLANDS/FLOOD STORAGE MITIGATION Mitigation Sites This project has utilized a planning process and mitigation sequencing that takes into account the February 1990 Memorandum of Agreement between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of the Army (Army) concerning the determination of mitigation under the Clean Water Act Section 404 (b) (1) guidelines. Efforts were made to locate and identify the least environmentally damaging practicable alternative that met the state project purposes. Preliminary study lines were identified and wetland involvement determined for each. The alignment which had the least wetland involvement was chosen in order to avoid, to the maximum extent practicable, potential impacts. After determining that wetlands takings could not totally be avoided with this project, steps were taken to minimize the adverse impacts as ,much as feasible. Project modifications included (1) reduction of right of way -from 164 feet to 120, feet through the affected wetlands, (2) reduction of pavement lane, widths from `].2 '"feet to 11 feet to accommodate a reduced cross-section (3) elimina of the ; adwa {a q steepest embankment A roadway grade to reduce 2.7 acres -of wetlands contiguous to this site. Based on field examination and subsequent analysis, it appears that sufficient opportunity exists proximal to the proposed project for on-site rather than off -site wetlands and flood storage mitigation to occur. A judicious selection of mitigation sites for this project allows for the balancing of the flood storage impact and compensation for wetlands losses within the same site. These sites, as shown on Figures 4a and 4b, (of the State EA/FONSI) were chosen for their potential to both recover flood storage taken by the roadway embankment and remain in close proximity to the areas of wetland losses. Table 1 lists the specific sites in priority with the estimated acres (wetlands) and acre-feet (flood storage) noted. These sites are listed as potential mitigation areas. Actual acreages of wetlands impacted and cubic yards of roadway All required within the flood storage basin will be determined in the final design phase. Coordination with the appropriate agencies for a Section 404 permit will be completed prior to agreement on specific sites and mitigation measures for this project. Approval to use lands within the 100-year floodplain (Wake County property) to mitigate flood storage and wetlands impacts has been advanced by the Wake County Board of Commissioners on July 2, 1990 (refer to letter of August 22, 1990 from -Wake County in Appendix C of State EA/FONSI). As has been noted, wetland acreage in the Crabtree Creek riparian zone is extensive, a result of the rise in water table associated with Lake Crabtree. However, some areas within the floodplain do not currently exhibit wetland characteristics due to their elevation above surrounding terrain. A total loss of approximately 2.7 acres of wetland will need to be mitigated. A combination of restoration and creation sites is suggested as the most effective approach to mitigate negative impacts on the wetland resource. Specific sites identified for mitigation potential are shown on Figures 4a and 4b. Sites ILA and 1B include approximately 2.0 acres immediately adjacent both sides of Crabtree Creek. Site ILA includes the western levee and disturbed areas in the riparian zone. The levee appears to be Congoree soil, while farther back from the creek on this side and slightly upslope, the original soil appears to be Altavista, well drained in the surface horizons but distinctly mottled at 3.5 to 4.0 feet. This mottling indicates excellent potential for conversion to wetland after upper layers are removed. Area 1B includes the levees of Congoree soil on the east bank between the creek channel and slackwater sloughs or tributary stream channels entering Crabtree Creek. Original forest cover has been removed in this location on both sides of the creek, from a point upstream of the proposed crossing, downstream to the lake itself. Mitigating here (Sites IA and 1B ) would provide an opportunity to restore bottomland forest similar to that proposed for clearing to???c+?omtn ate the ro'ec?t.. Grading 3.5 feet or moresof the exishng?? match the surroundini bottdmland After grading is complete, wetland tree species such as River liirc etnla mgrs), Green ash Fraxinus pennsylvanica), Overcup oak uercus lyrata), and Swamp chestnut oak uercus michauxii), should be planted to compensate for forested wetland removed along the new causeway. Sites 2 and 7, located approximately 1,400 + feet northeast of the proposed ROW, includes 3.3 acres along the southeastern shore of Lake Crabtree. The soil currently here, Wehadkee, is prone to seasonal flooding, with a seasonally high water table approximately at the surface. Observation in May and June, hence during the current growing season, reveals dry conditions and no wetlands species on the terrace just above the lake level. However, shoreline uncus and cattail colonies with observed depth to saturation of about 2.5 feet on the terrace suggest that grading to a contour even with the adjacent marginal wetland area (approx. 2.0 feet) will create a more extensive marsh area between the lake and the grass covered sewerline ROW farther upslope. Prevailing onshore winds from across the lake will also tend to drive water against this shore, thus periodically flooding the area. No tree planting is proposed here because of the expected hydrologic regime. Due to the distance from the project and its small size, Site 3, (not shown) consisting of 0.2 acres has been rejected as a feasible mitigation site. Site 4, contiguous with Site IA, also contains the Altavista soil discussed previously in connection with Site IA. Therefore, removing surface material to an average depth of 4.0 feet, even with or perhaps below lake level would expose soil capable of supporting wetland tree species, as in Site 1A. The same species of oaks and river birch are proposed for planting here as required.

These sites could be graded down an average of 2.5 feet to further offset flood storage capacity loss and mitigate wetlands with a similar scheme as noted for sites 2 and 7. As noted in Table 1 the total flood storage capacity recovered with sites 1A, 1B, 2, 5, 6, and 7 is estimated at 15.6 acre-feet. Additional recovery may or may not be needed to achieve the 182 acre-feet depending upon final design calculations: Should additional storage be required, Site 4 is proposed to be used only as needed to mitigate the remaining flood storage capacity deficit. Permit Coordination In preparing this environmental report, information was solicited from a meeting with Mr. Ken Jolly (U.S. Army COE) and subsequent telephone discussion with Mr. Wilson Laney (USFWS). The step-down procedure for permit application requires that, first, this project qualify on the basis of demonstrated need and, second, that all reasonable attempts be made to minimize impacts on waters of the United States, including wetland acreages. Assuming these conditions are met, the project is proposed to be permitted under Section 404 of the Clean Water Act with an appropriate mitigation plan developed to satisfy the current federal goal of no overall net loss of wetland values and functions. Monitoring Plan As part of the mitigation effort for this specific project a monitoring plan to insure that permit conditions are complied with has been developed by the N.C. Department of Transportation in coordination with the Corps of Engineers and is attached. PROJECT 9.8050364 U-2403 GUIDELINES FOR WETLAND MONITORING PROGRAM I.

Due to the nature of the comments additional time was necessary to review the application and prepare the appropriate responses. The basis for the projected traffic demand is data collected and prepared by the North Carolina Department of Transportation through their Statewide Planning and Research Units. Traffic counts are taken on various highways and entered into computer models along with data on population growth rates, economic activity, planned highway improvements and historic traffic patterns. Traffic projections for roadways within this project study area were prepared by taking this data and forecasting future demands along I-40, Harrison Avenue, NC 54 and other roads in the vicinity. These traffic numbers are further refined by traffic analysts in the Research Unit to reflect existing and/or planned improvements or other factors which may not have been previously taken into account. The traffic projections approved for use by NCDOT are shown on Figures 2a and 2b of the approved EA/FONSI for the project. The traffic projections made for the Evans Road project do take into account the recent six-lane widening of I-40 and the planned improvement of I-40 to eight lanes. The projected increase in traffic for the Harrison Avenue interchange is not 3,900 vehicles per day by 2010 as stated in your comments. The correct increase is projected to be 14,800 vehicles per day. The 3,900 vpd figure was apparently derived from the difference between the 2010 projections for the road network comparing the traffic with and without the Evans Road Extension. Page 2 Mr. Ron Ferrell April 16, 1991 Upgrading the existing roads (NC 54 and North Harrison Avenue) and the interchange to accommodate the projected traffic demand will not by itself adequately address the future traffic needs in the study area. Capacity analyses were performed to evaluate the existing road network to see if it could handle the future traffic. The analyses showed that the existing lanes without improvements would suffer breakdown conditions (level-of-service F). Widening NC 54, North Harrison Avenue to four and five lane sections respectively, also results in levels-of-service E and F. These levels of service for arterial facilities are considered unacceptable for adequate traffic operations. The capacity analyses work sheets supporting these findings were previously supplied and approved by NCDOT and submitted to the Corps on January 23, 1991 in response to their request for additional detail. Even by adding the multi-lane section of Evans Road Extension and widening NC 54 and North Harrison Avenue we find only a marginal improvement in level-of-service for NC 54 and North Harrison Avenue. It is our opinion that six lanes will ultimately be required on NC 54 and North Harrison Avenue as well as major improvements to the North Harrison Avenue interchange with I-40 in order to achieve the desirable levels-of-service (LOS C or D) for this network. The basis premise found in this analysis is that the rapid growth of the Cary area, specifically the north Cary area, over the next 10 to 20 years is demanding additional infrastructure be supplied to handle this increase in population and business activity. Simply widening the existing two roads which provide north-south travel in the north Cary area will not be sufficient to satisfy the traffic demands at acceptable levels. In reference to the mitigation plan, a summary of the mitigation measures offered is contained within the approved EA/FONSI document for this project. Additional information concerning the mitigation measures were provided to the Corps of Engineers in the Section 404 permit application, including a monitoring plan developed by NCDOT. The mitigation and monitoring plans were reviewed in light of this comment and additional detail has been prepared and was submitted to the Corps. A copy of this is attached for your information. NCDOT continues to feel that a two (2) year monitoring program is adequate. Other recent permits in more sensitive wetland areas have been acquired utilizing the two (2) year monitoring plan. Additional detail on size, height and plant spacing is provided in the attached Wetland Monitoring Program. An acceptable survival rate of 30% population planted and natural succession is proposed. In addition, a planting schedule and landscape design plans are being prepared by the Roadside Environmental Unit of NCDOT and will be included within the final design plans.

Army Corps of Engineers Public Notice Action ID 199100143 dated December 13, 1990 which describes a project proposed by North Hills Properties, Inc. of Raleigh. The project, involving wetland fill amounting to 2.64 acres to facilitate construction of a new four lane connector highway, is located in the Crabtree Creek flood plain at Cary, in Wake County. Although the viewpoint record is not complete due to the continuing of the processing for the 401 Certification, the responses to date are significant and should be considered at this time. Three key agencies have entered sound objections and/or expressions of concern. Having reviewed other impacts to the Crabtree Creek in recent years, the writer shares the concern with additional proposed fragmentation of this important urban greenway, wildlife corridor and urban runoff filter being proposed. Fragmentation is generally considered the most difficult, and perhaps, impossible impact to mitigate. Those agencies submitting substantive comments and a summary of each follows. Agency submittals are enclosed for your further review. Division of Parks and Recreation, Natural Heritaee Proaran - ".... "Concerns are so strong that the program feels the road should not be built. There will be considerable damage to the natural environment, particularly regarding fragmentation of a bottom- land and swamp". "The EA/FONSI does not appear to have made a strong enough case to justify need for this new road, which bisects a wide floodplain of significant natural features". Division of of Community Assistance - "....questions the benefit to the public in light of the destruction of these wetlands". "Public Notice No. 00143 does not demonstrate a substantial public or private need which would not be met if the project was not built as proposed". P.O.

By letter dated January 25, 1991, you recommended that the permit be denied because of anticipated adverse environmental impacts, the availability of practicable alternatives, and concerns regarding the proposed wetland restoration and creation. By letters of January 23 and April 10, 1991 (copies enclosed), the applicant provided information which addresses your concerns. We are anticipating final action on this application, and would appreciate your comments regarding this additional information on or before May 17, 1990. Based on past experience with similar applications, we believe that a meeting between the applicant and our respective offices might expedite the application process. Your participation in such a meeting is requested. Coordination to arrange a meeting time and place will occur shortly.

Box 1890 Wilmington, North Carolina 28402-1890 Attention: Regulatory Branch Dear Colonel Tulloch: Reference is made to your August 5, 1991, letter concerning an application by North Hills Properties, Inc. to fill wetlands for construction of a four- lane highway in Cary, Wake County, North Carolina (Action ID. 199100143). This report is submitted in accordance with provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.). The U.S. Fish and Wildlife Service (Service), in our May 15, 1991, report, objected to permit issuance based on the probability of practicable alternatives that would avoid wetland impacts. If such alternatives were lacking, the Service required compensatory mitigation of fish and wildlife habitat values lost to project construction. In your recent letter you stated that the Corps had evaluated additional information provided by the applicant and accepted their argument that no practicable alternatives exist. In light of your decision, the Service will not object to permit issuance, provided that any permit issued is conditioned such that the fish and wildlife habitat values to be lost are fully mitigated. We expect to work with your staff and the applicant to develop a mitigation plan at a meeting scheduled later this month. The Service appreciates the opportunity to comment on this project. Please advise us of any action taken by the Wilmington District, Corps of Engineers. You may contact David Dell, Permit Coordinator, of this office if you have any question regarding our recommendations. Sincerely, &Vff L.K.

Dear Mr. Wright: Construction of this project began on November 18, 1992 under authority of the above-referenced individual permit. Discussions just prior to this date between the Corps of Engineers (COE) and the permittees (North Hills Properties, Inc., Silverton, Inc., and the North Carolina Department of Transportation) revealed differing interpretations of Permit Special Condition a.3. Special Condition a.3. states "Construction of the mitigation sites will be initiated at such time to provide for planting of seedlings the first suitable planting period (November 15 through March 15) following commencement of project construction." The permittees' interpretation was that if a project began after the start of the mitigation planting window then the condition would allow for an extra year to complete the mitigation plantings. The COE interpreted the condition such that if any part of the project began during any portion of the planting window then all mitigation planting must be finished during this "initial" planting period. The permittees in attempting to complete this project as expeditiously as possible may choose to begin construction of mitigation site 4 should weather and ground conditions over the winter months allow such activity. Access to site 4 requires minor filling of a small area of existing wetlands on the west side of Crabtree Creek and thereby would trigger the permit special conditions. However, due to the winter conditions only a short period of acceptable construction time may be available. This time frame will probably not be sufficient to complete all the required grading and planting of site 4, and most assuredly would be insufficient time to complete work for all the mitigation sites required for this project under the Corps interpretation. In addition, the material excavated during grading of the remaining mitigation sites is proposed for use as roadway fill for this project. Since construction may be suspended for long portions of the winter months these sites should not be disturbed until such time as the borrow material can be effectively moved and used as project fill. Therefore, in accordance with the general and special conditions of the individual Section 404 permit for this project, the permittees hereby request a modification of the permit to reflect a necessary change in the language of Special Condition a.3. to allow for flexibility in the construction schedule of the mitigation sites. The permittees request that Special Condition a.3. be revised to read as follows: "Construction of the mitigation sites will be initiated at such time to provide for planting of seedlings during the first or second suitable planting period as necessitated by construction phasing or scheduling." This or other similar language as preferred by COE would allow for a logical compliance to the permit conditions. By copy of this letter, we also request NC DEHNR Division of Environmental Management 401 Water Quality Certification for the permit modification. If there are any questions concerning this request please call Mr. Ron Hain, at (919) 856-1777. Thank you for your consideration of this matter. Sincerely, BURTON, ADAMS, KEW & KING, INC.

STATE HIGHWAY ADMINISTRATOR Mr. G. Wayne Wright Chief, Regulatory Branch Department of the Army Wilmington District Corps of Engineers P.O. Box 1890 Wilmington, North Carolina 28402-1890 'M p ,tq SIP ?s ? RE: Proposed Evans Road Extension over Crabtree Creek in Cary, . NCDOT Project U-2403, COE Action ID # 199100143 Dear Mr. Wright: Thank you for the opportunity to expand upon our recent discussions of reasonable alternatives for the Evans Road Extension project. At our last meeting on June 26, 1991 considerable discussion centered on the apparent availability of a practicable alternative to extending Evans Road across Crabtree Creek to Aviation Parkway. That alternative being the widening and improvement of a section of NC 54 from Maynard Road in Cary to Aviation Parkway. The supposition that improving NC 54 provides a reasonable and practicable alternative to extending Evans Road cannot be supported after carefully examining the Greater Raleigh Urban Area Thoroughfare Plan and comparing the costs associated with the two alternatives in question. A brief explanation of the transportation planning process for the Cary area may help in understanding why improvements to NC 54 do not meet the project need. The Federal government requires under Section 134 of Title 23 that urbanized areas prepare a transportation plan or program that is consistent with the comprehensively planned development of the area. The plan, called the Thoroughfare Plan here, integrates An Equal Opportunity/Affirmative Action Employer Page 2 Mr. G. Wayne Wright July 22, 1991 transportation, land use and environmental considerations. This process which includes regional and corridor planning has been completed by the state for this area. Some factors which have gone into this process included forecasts of vehicle miles of travel, travel demand, highway and travel speeds, traffic diversion, accident rates and traffic peaking characteristics. Public hearings were held to solicit public input and discussion. The data and input collected helped in the development of the long range Thoroughfare Plan for the area. (A portion of the Thoroughfare Plan Map is attached for your use.) Wake County, Raleigh, Cary and all other cities and towns have approved (March 1986 - July 1988) and incorporated the Thoroughfare Plan into their own long range development and land use plans. They have subsequently based many of their decisions and public expenditures over the years for placement of water and sewer lines, pump stations, fire departments, recreational areas, residential and commercial land use approvals and industrial zoning on this approved Thoroughfare Plan. The Evans Road corridor was developed as part of this process and substantial local planning by the Towns of Cary and Morrisville has taken place based on this route. An example includes the current project by Cary to install a 16 inch water main along Evans Road. The water line is a critical section in Cary's Master Water Plan and is needed to supplement circulation and provide a loop system. It is also the primary connector between Weston and Aviation Parkway and the Raleigh-Durham International Airport. Of more important specific interest to us however is that inspection of the Thoroughfare Plan reveals the future Evans Road alignment as a replacement corridor for NC 54 northwest of Cary. As you study the Thoroughfare Plan Map you will note that the NC 54 and Hillsborough Street facilities which are shown as existing major thoroughfares enter Cary from Raleigh and merge just north of downtown Cary. From this point near Harrison Avenue the merged highways follow the existing NC 54 alignment until it reaches Evans Road near Maynard Road. Here the continuity of this major thoroughfare incorporates Evans Road and leaves the NC 54 alignment. The Evans Road corridor extends to Aviation Parkway, bypasses Morrisville and continues until it interchanges with Koppers Road. From this junction Evans Road is proposed as an access controlled freeway and interchanges with the future Northern Wake Expressway. It is readily apparent that Evans Road has been designated as the major route out of Cary to the northwest replacing NC 54. The rationale for this selection is the very poor horizontal and vertical alignment along NC 54, as well as significant interference from the adjacent railroad line and numerous driveways and residences. NC 54 keeps its designation as a major thoroughfare northwest of Cary, however it no longer provides the continuity of the primary through route and its roadway deficiencies preclude significant improvement without extensive costs. Page 3 Mr. G. Wayne Wright July 22, 1991 As shown on the Thoroughfare Plan, NC 54 is earmarked for replacement as the primary thoroughfare out of Cary by Evans Road. Consequently, any improvement to a section of NC 54 would ignore and in fact circumvent the entire comprehensive planning process that has taken place over many years. In effect, the entire Evans Road corridor would be jeopardized by this action. Previous discussion also involved a misunderstanding that NC 54 would have to be widened in the future anyway. Statements to the effect that even with the Evans Road Extension, NC 54 would require four lanes or ultimately six lanes are observations made by the'engineers after performing the technical analyses of highway segment capacity and level of service on a given fixed network with projected traffic volumes. They were intended only to illustrate the need for additional travel lanes in the area under study. Whether they were added to NC 54 or another future route is strictly problematic. In the case of NC 54 it is probably not feasible (cost effective) to totally reconstruct the road to bring it up to acceptable standards as a multilane facility. Currently, no projects are planned or programmed for improving NC 54 in this area. NCDOT has recognized this difficulty in upgrading NC 54 and placed priority for highway improvements on the Evans Road corridor. If we agree for the sake of argument however, that improving NC 54 is a reasonable alternative it is only prudent to compare the two alternatives on an equal basis. Our analysis selected appropriate (and identical) beginning and ending terminals for NC 54 and Evans Road. The beginning point is the Maynard Road intersections with both routes. The ending terminus is the Aviation Parkway intersections with each. The approximate length is 2.9 miles. Our analysis looked at the traffic capacity calculations and a determination of the number of travel lanes required to achieve the appropriate Level of Service (LOS) D for a twenty (20) year design period. A cost estimate to provide these roadway segments was prepared for each alternative. The capacity calculations (available for review) indicated NC 54 requires a b lane highway with multiple turning lanes at the intersections of Maynard Road, Cary Parkway, Weston Parkway and Aviation Parkway. Evans Road has previously been analyzed and requires a basic four lane or five lane (center turning lane) highway from Maynard Road to Aviation Parkway. Turning lanes will also be needed on the same intersecting roads. An additional 1.0 mile section of existing Evans Road requires widening from two lanes to the five lane section. This section was included in the analysis and cost estimate preparation. Page 4 Mr. G. Wayne Wright July 22, 1991 The cost estimate for each alternative as analyzed is shown in the following table. COST ESTIMATE NC 54 Evans Road Construction $7,266,000 $2,650,000 (U-2403) $1,600,000 (1 mile addition) Right of Way $1,570,000 Donated (U-2403) $ 510,000 (1 mile addition) TOTAL $8,836,000 $4,760,000 The cost for NC 54 included reconstruction of the roadway to a 50 mph design criteria for a six lane curb and gutter road with turning lanes and widening the existing bridge over Crabtree Creek. The Evans Road estimate included the previously calculated cost for the extension over Crabtree Creek and the widening and geometric improvement of a one mile section of Evans Road that connects to Maynard Road. It is obvious after comparing the cost estimates for the two alternatives that improving the substandard section of NC 54 does not favorably compare with continuing with the extension of Evans Road. The extreme cost difference of over 4 million dollars can be primarily attributed to the major reconstruction required for the horizontal and vertical alignment along NC 54. This high cost per mile to bring NC 54 up to acceptable standards is a primary reason why NCDOT has placed priority on the development of a new corridor in the future to handle the through traffic demand currently accommodated on NC 54. Based upon this analysis it should be apparent that reconstructing this section of NC 54 cannot be considered a reasonable or practicable alternative to the Evans Road Extension. In summary, there are limits to what can be considered a "reasonable or practicable alternative" in complying with Executive Order 11990 and the section 404 (b)(1) guidelines. If an alternative does not meet the projects' purpose or satisfy the project needs then the alternative is not considered to be prudent nor practicable. In this case, we can see that improving a section of NC 54 does not satisfy the project need because (1) it is not consistent with the overall comprehensively developed and approved Thoroughfare Plan for the area and (2) even assuming it was a reasonable alternative the cost difference between the two alternatives of approximately four million dollars precludes it from being accepted as a practicable alternative.

RUST Environment & Infrastructure 5510 Six Forks Road Raleigh, North Carolina 27609 Dear Mr. Lewis: Reference the Department of the Army permit issued on September 2, 1992, and subsequent modification, for discharges-of fill material to facilitate construction of the Evans Road extension, NCDOT Project No. U-2403, in Cary, RWe=suht?r-, North Carolina. Reference also your letter of July 23, 1993, on behalf of the permittees, requesting modification of the permit to allow a change in the size and location of the mitigation-sites, and to authorize, after-the-fact, a temporary construction access road. Specifically, you propose to change the nature of four previously proposed flood storage mitigation sites 2,5,6 and 7 on-the southeast side of make _ Crabtree to provide 4.08 acres of.bottomland hardwood mitigation. This change would be to compensate for a 2.13 acre shortfall in the-actual-size of the originally proposed hardwood mitigation sites,-and to ensure survival requirements on a minimum of 6.47 acres, as originally required by the permit. The additional hardwood sites would be graded to elevation 276.5 and prepared and planted as required for the original sites. The existing temporary construction road on the sewerline easement is necessary for access to mitigation sites 2,5,6, and 7. All of the fill material for the road will be removed to high ground after construction is completed, and preconstruction elevations will be restored. The permit is hereby modified to authorize the mitigation plan changes and temporary access road described above, subject to the following additional condition: ?- ? ,s r t -2- The temporary road fill will be entirely removed to upland areas following completion of the construction activity, and the affected areas restored to pre-project conditions. It is understood that all other conditions of the original permit remain applicable and that the expiration date is unchanged. FOR THE COMMANDER James H.
