from US 70 to NC 100 Alamance County State Project No 8 2472001 _v Federal Aid Project No STP 0701(7) TIP No U 3110 Sections A and B f This application letter serves to re lace the original permit application dated July 10 2002 Due to a request from the Division of Water Quality the Natural Stream Design has been changed Stream impacts and stream relocation length reported earlier are both -rte slightly less Please disregard the July 10 2002 permit application The North Carolina Department of Transportation proposes to construct connectors to and widen Cook Road (SR 1311) from US 70 to NC 100 (Haggard Road) The proposed project will aid in the completion of a continuous north south route in western Alamance County This project is part of the Western Alamance Loop and adjoins the proposed St Marks Church Road relocation project (TIP No U 2905) at the southern terminus and the Elon College Bypass project (TIP No U 2406) at the northern terminus Under TIP U 2406 (let in March 2000) a new connector was constructed from NC 100 to Manning Avenue (SR 1503) Under TIP U 3110 NC 100 will be bridged via a flyover and connected to this new NC 100 connector approximately 1 000 feet north of NC 100 When the flyover is completed the unused portion of the NC 100 connector will be lifted For clarity the relevant design sheets from U 2406 are attached to this permit Section A of the proposed project has final design However since Section B is not due to be let until 2007 there is only preliminary design The 4 2 mile proposed project involves MAILING ADDRESS TELEPHONE 919 733 3141

Norfolk Southern Railway (Section B) and one over NC 100 (Section B) The latter two bridges involve significant gr�,ad`e `separations In addition a sewer line will be relocated simultaneous with project construction on Section A Project design requires the replacement of an existing utility (sewer) line underneath a wetland adjacent to Michael Branch Impacts to this wetland are already proposed with road construction The length of line through the wetland will be approximately 252 feet Additional permanent impacts to jurisdictional wetlands will result from mechanized clearing which will be necessary for installation and maintenance of the line The wetland area to be cleared will be kept to a minimum Preconstruction contours will be restored Any excess material will be removed to upland areas and exposed wetland areas revegetated within 1 days of completion Impacts due to mechanized clearing have been calculated and included in total impacts for this project This application,package consists of this cover letter ENG Form 4345 (revised) 8 `/2 x 11 inch permit drawings (revised) U 2406 design sheets (11x17) of the connector to the northern terminus of U 3110A natural stream design plan for onsite stream relocation (revised) and half size plans (revised final for Section A and preliminary for Section B) Purpose and Need The purpose of the proposed project is to provide a link in the Western Alamance Loop which is on the Alamance County Thoroughfare Plan Also the construction of the project will decrease traffic along Williamson Avenue (SR 1301) which goes directly through the Town of Elon College Summary of Impacts The proposed project is located in the Cape Fear River Basin Hydrologic Unit 03030002 All impacts on jurisdictional areas are contained within Section A of the proposed project Impacts consist of a total of 0 8 acres of permanent riverine wetland impacts and 777 linear feet of jurisdictional stream impacts Utility Impacts It will be necessary to relocate the sewer line currently running parallel to Michael Branch (sheet 15 of 19) The utility line will be relocated underneath the proposed roadway Additional impacts will result from wetland fill required to install the sewer line outside of the roadway footprint and tie it in to existing sewer lines In order to provide maintenance access mechanized clearing will also be necessary The impacts from this relocation although minimal have been calculated and included with this permit application These impacts are included in the total impacts listed at the beginning of the section and are included in the impacts listed on the permit drawing summary sheet (Sheet 19 of 19) Summary of Mitigation The project has been designed to avoid and minimize impacts to jurisdictional areas throughout the NEPA and design processes Detailed descriptions of these actions are presented elsewhere in this application Compensatory mitigation for the remaining impacts consist of • 780 feet of on site stream relocation using natural channel design techniques which is described in detail later in this application 2/9 • 0 8 acres of nverme wetland impacts will be mitigated at a ratio of 2 1 by using the North Carolina Wetland Restoration Program (WRP) We will provide the WRP with a payment of $38 400 which is the cost of 1 6 acres of riverine wetlands at a rate of $24 000 per acre (Please refer to the attached WRP commitment letter dated May 9 2002 ) PROJECT SCHEDULE Schedule Section A of this pioject is scheduled to be let for construction in February

100 (Haggard Road) NEPA DOCUMENT STATUS An Environmental Assessment (EA) was submitted by the NCDOT in compliance with the National Environmental Policy Act and was approved on January 24 1997 A Public Hearing was held on April 29 1997 and the Finding of No Significant Impact ( FONSI) was approved on January 30 1998 The documents addressed Sections A and B of the proposed project After the documents were approved they were circulated to federal state and local agencies Copies of the EA and FONSI have been provided to regulatory review agencies involved in the approval process Additional copies will be provided upon request The subject project is in compliance with 2' ) CFR Part 771 111(f) which lists the Federal Highway Administration (FHWA) characteristics of independent utility of a project 1) The project connects logical termini and is of sufficient length to address environmental matters on a broad scope 2) The project has independent utility because it proposes a direct link from US 70 to NC 100 and is therefore a usable and a reasonable expenditure even if no additional transportation improvements are made in the area and 3) Because U 3110 is part of the Western Alamance Loop of the Alamance County Urban Thoroughfare Plan construction of this project has been coordinated with other adjoining transportation improvement projects TIP U 2905 at the southern terminus was permitted under a Section 404 NW 14 permit and a Section 401 Water Quality Certification in July 2001 TIP U 2406 at the northern terminus was permitted under a Section 404 permit and a Section 401 Water Quality Certification in December 1999 Both permit application processes followed the 3/9 FHWA compliance process Therefore consideration of alternatives for other reasonably foreseeable transportation improvements was not restricted RESOURCE STATUS Delineations Wetland delineations were conducted on September 29 2000 by NCDOT Biologists Elizabeth Lusk and Shannon Simpson using the criteria specified in the 1987 Corps of Engineers Wetland Delineation Manual Mr Eric Alsmeyer of the USACE Raleigh Regulatory Field Office verified the delineations in the field on July 12 2001 Streams were delineated on that same day and field verified by Eric Alsmeyer and John Hennessy NCDWQ The attached permit application package consists of drawings depicting jurisdictional impacts As previously mentioned the project will result in a total of 0 8 acres of permanent riverine wetland impacts and 777 linear feet of jurisdictional stream impacts U 3110 Characterization of Jurisdictional Sites (Table 2) This section has 0 8 acres of jurisdictional riverme wetlands and 777 feet of jurisdictional streams There are no temporary wetland impacts or any impacts to ponds WETLANDS There are two wetland sites both in Section A These sites are characterized as piedmont bottomland hardwood forest seep and drained beaver impoundment They are both located adjacent to Michael Branch The dominant vegetation in the seep area is false nettle (Boehmeria cylindrica) jewelweed (Impatiens capensis) Japanese grass (Microstegium vimineum) and tag alder (Alnus serrulata) The beaver impounded area consists of sparsely populated green ash trees (Fraxinus pennsylvanica) rush (Juncus sp ) Rotala ( Rotala sp ) and sedge (Carex sp ) STREAMS There are two crossings of Michael Branch (DEM classification C NSW [Index No 15 19 52 12/1/83]) This perennial stream flowing only through Section A has a good riffle /pool sequence and high sinuosity and provides suitable habitat for fish and macrobenthos Common mussels (Elliptio sp ) were found in one portion of the stream Table 2 Jurisdictional Impacts on U 3110 Includes fill ercaNauon and mechanized clearm, Natural Channel

animals with Federal classification of Endangered (E) or Threatened (T) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973 as amended As of March 22 2001 the U S Fish and Wildlife Service (FWS) does not list any federally protected species for Alamance County CULTURAL RESOURCES Per the EA there are no archaeological or historic issues associated with the proposed project Archaeology There are no properties either listed or eligible for listing in the National Register of Historic Places in the area of potential effect As a result the SHPO verified that no archaeological study was required (phone conversation November 1996) (see EA) Historic In a letter dated May 31 1995 the NC State Historic Preservation Office (SHPO) stated that there was one structure of historical significance within the general area of the project However an NCDOT Architectural Historian surveyed the project area and found no structures of historical importance in the area of potential effect The SHPO and the FHWQ concurred with NCDOT s conclusion (see Appendix C in the EA) FEMA COMPLIANCE The project has been coordinated with appropriate state and local officials and the Federal Emergency Management Agency (FEMA) to assure compliance with FEMA state and local floodway regulations Per NCDOT s agreement with FEMA NCDOT designers performed the HEC RAS Hydrologic Model to design an acceptable flood stage 5/9 MITIGATION OPTIONS The Corps of Engineers had adopted through the Council on Environmental Quality (CEQ) a wetland mitigation policy that embraces the concept of no net loss of wetlands and sequencing The purpose of this policy is to restore and maintain the chemical biological and physical integrity of the Waters of the United States Mitigation of wetland and surface water impacts has been defined by the CEQ to include avoiding impacts minimizing impacts rectifying impacts reducing impacts over time and compensating for impacts (40 CFR 1508 20) Executive Order 11990 (Protection of Wetlands) and Department of Transportation Order 5660 IA (Preservation of the Nations Wetlands) emphasize protection of the functions and values provided by wetlands These directives require that new construction in wetlands be avoided as much as possible and that all practicable measures are taken to minimize or mitigate impacts to wetlands The NCDOT is committed to incorporating all reasonable and practicable design features to avoid and minimize wetland impacts and to provide full compensatory mitigation of all remaining wetland impacts Avoidance measures were taken during the planning EA/FONSI and design phases minimization measures were incorporated as part of the project design AVOIDANCE All wetland areas not affected by the project will be protected from unnecessary encroachment No staging of construction equipment or storage of construction supplies will be allowed in wetlands or near surface waters • Site 1 The original alignment for U3110A was close to the 5 acre ponds that extend from STA 15 +60 to 18 +60 RT —L Alignment was shifted to move away from the spillway structure to avoid impacting the ponds MINIMIZATION Minimization includes the examination of appropriate and practicable steps to reduce the adverse impacts Minimization techniques were implemented as follows • Site 1 The original alignment for U3110A was close to the 5 acre ponds that extend from STA 15 +60 to 18 +60 RT —L In addition to avoiding pond impacts the realignment at this site allowed for more grass swale length and lessened the impact on wetland areas • Site 1 The original design as presented in the EA included a two barrel reinforced concrete box culvert at this southernmost crossing of Michael Branch In order to minimize and avoid impacts the design was changed to a bridge with a structure 130 feet in length at a cost of approximately $700 000 This structure 'A ill provide improved flood conveyance and help maintain the continuity of the stream morphology and community in this reach While impacts to Michael Branch are still necessary a bridge will allow natural stream design of the relocated portion of Michael Branch which would not have been possible A nth a culvert In addition 6/9 naturalizing the relocated stream will improve the functions and values of Michael Branch which is currently incised and down cutting Note Because of the skew of the creek and floodplain to the proposed road a 600- oot bridge would be required in order to avoid all impacts to Michael Branch Avoidance by realignment of the road is limited by ponds and homes to the east Moving further westward would prevent connection to the southern connector (U 2905) and the northern connector (U 2406) • Floodplam Functions The NCDOT has purchased additional permanent drainage easement (PDE) in the floodplain to the west of the first crossing of Michael Branch This additional 2 5 acres will ensure maintenance of the floodplain functions • Water velocities and water quality (Reference permit drawing sheets 5 and 6 of 19) The original highway geometric for this project allowed for drainage to be collected for significant distances and discharged to a single point While this practice would be hydraulically efficient detrimental aspects were foreseen with regards to water quality For this reason the drainage was separated into smaller systems that allowed for more vegetated filtering lower velocities and lower single point volumes to be distributed to Michael Branch • Stormwater runoff treatment • This project will utilize turf reinforcement mats (TRMs) instead of rip rap in sections where velocities are above the acceptable threshold for stable vegetation The TRMs will allow for vegetation to be used and increase the amount filtration that stormwater runoff will receive from grassed swales • Water collected in the bridge deck drains will not be directed into the stream • Best Management Practices (BMPs) NCDOT has committed that Sediment and Erosion Control Guidelines for BMPs for Protection of Surface Waters will be adhered to during construction to minimize potential negative environmental impacts (see FONSI) • Sediment and Erosion Control Measures NCDOT will stipulate that sediment and erosion control measures not be placed in wetlands unless it is absolutely necessary to place silt fences on wetland boundaries to contain erosion caused by the sheet flow of water This commitment will be incorporated into the construction contract awarded for the proposed project (see FONSI) • Reve eta ation Within 15 days of construction completion vegetation will be reestablished on exposed areas with judicious use of pesticide and herbicide • Upland Borrow NCDOT will stipulate borrow material be taken from upland sources in the construction contract awarded for the proposed project (see FONSI) • Drainage There A ill be no direct discharge of road drainage into Michael Branch 7/9 • Slopes Fill slopes in wetlands are at a 2 1 ratio • Ditching It is the policy of the NCDOT to eliminate lateral ditching in wetlands as much as possible thus preserving the hydrology of adjacent wetlands This proposed design has eliminated lateral ditches through wetlands COMPENSATION The primary emphasis of the compensatory mitigation is to reestablish a condition similar to that that would have existed if the project were not built As previously stated mitigation is limited to reasonable expenditures and practicable considerations related to highway operation Mitigation is generally accomplished through a combination of methods designed to replace wetland and stream functions and values lost as a result of construction of the project These methods consist of creation of new wetlands from uplands borrow pits and other non wetland areas restoration of wetlands and enhancement of existing wetlands and stream channel relocation FHWA STEP DOWN COMPLIANCE All compensatory mitigation must be in compliance with 23 CFR Part 777 9 Mitigation of Impacts that describes the actions that should be followed to qualify for Federal aid highway funding This process is known as the FHWA Step Down procedures I Consideration must be given to mitigation within the right of wav and should include the enhancement of existing wetlands /streams and the creation of new wetlands and naturalization of relocated stream channels in the highway median borrow pit areas interchange areas and along the roadside 2 Where mitigation within the right of way does not fully offset wetland /stream losses compensatory mitigation may be conducted outside the right of way including enhancement creation and preservation Compensatory Wetland Mitigation The North Carolina Wetland Restoration Program (WRP) has committed to providing 16 acres of rrverine wetland mitigation at a ratio of 2 1 for the 0 8 acres of riverine wetland impacts We will provide the WRP with payment of $38 400 which is the cost for 16 acres at the rate of $24 000 per acre (see attached letter dated May 9 2002) Compensatory Stream Mitigation The 777 linear feet of jurisdictional stream impacts will be mitigated by 780 feet of on site relocation using natural stream channel design at a mitigation ratio of 1 1 (see permit drawings for Rosgen analyses and natural channel design schematics) 8/9 i REGULATORY APPROVALS Application is hereby made for a Department of the Army Individual 404 Permit as required for the above described activities We are also hereby requesting a 401 Water Quality Certification from the Division of Water
