Army Corps of Engineers Regulatory Field Office 69 Darlington Ave. Wilmington, NC 28403 Attn: Mr. Brad Shaver USACE NCDOT Division 3 Coordinator Dear Sir: Subject: Application for an Individual Section 404 Permit, and Individual Section 401 Water Quality Certification for the replacement of Bridge Nos. 16 and 20 on NC 211 over Honey Island Swamp in Brunswick County. WBS Element No. 17BP.3.R.26. This application also includes the Preliminary Jurisdictional Determination Request Form. The North Carolina Department of Transportation (NCDOT), Division of Highways, proposes to construct Bridge Nos. 16 and 20 on NC 211 over the Honey Island Swamp. The project is approximately 0.474 miles in length. The purpose of this letter is to request approval for a Section 404 Individual Permit, and an Individual Section 401 Water Quality Certification. In addition to this cover letter and ENG Form 4345, this application package includes permit drawings, half size roadway plans, Preliminary Jurisdictional Determination request form, USACE jurisdictional forms, and NCDWR stream forms. 1.0 Purpose and Need The purpose for this State Project No. 17BP.3.R.26 is to preserve the mobility and safety of the traveling public by replacing the existing 59-year old structurally deficient bridges that can no longer be addressed by maintenance activities. Bridge No. 16 is a 3-span timber bridge, 25.4 feet wide by 52.6 feet long. Bridge No. 20 is a 3-span timber bridge, 25.3 feet wide by 52.4 feet long. They span Honey Island Swamp on paved NC 211. The underground telecommunication and fiber optic cables will be relocated aerial onto the joint use power poles. 2.0 Project Description The replacement structure for Bridge No. 16 will consist of a single span 45” concrete girder bridge approximately 80 feet long and 34.25 feet wide. The replacement structure for Bridge No. 20 will consist of a single span 45” concrete girder bridge approximately 85 feet long and 34.25 feet wide. These bridge lengths are based on final design information and were set by hydraulic requirements. The bridges will be of sufficient width to provide for two 12-foot lanes 2 with offsets varying from 4.1 feet to 5.0 feet on Bridge No. 20 with 0.06 superelevation across the bridge and 4-foot offsets on Bridge No. 16 on each side in normal crown. The roadway grade of each new structure will be approximately the same as the existing grade. The land use adjacent the swamp is primarily forest and game land. The basin character is Coastal Plain Rural. 3.0 Summary of Impacts Waters of the U.S.: Proposed impacts to jurisdictional areas total 0.76 acres. The impacts are as follows: 0.56 acres of fill in wetlands, 0.16 acres of permanent mechanized clearing in wetlands and 0.04 acres of forested wetlands converted to herbaceous wetlands within the 30 foot wide aerial utility corridor. Temporary impacts consist of 0.01 acres of hand clearing at the bridges and 0.21 acres of hand clearing within the 30 foot wide aerial utility corridor due to utility relocations. 4.0 Summary of Mitigation The proposed construction of Bridge Nos. 16 and 20 over Honey Island Swamp will permanently impact 0.76 acres of jurisdictional riparian wetlands that will require mitigation. The unavoidable impacts to jurisdictional riparian wetlands will be offset by mitigation provided by NCDOT through on-site replacement (restoration) of Riverine Swamp Forest community. A total of 0.76 acres of wetlands will be restored on-site. The forested wetland community portion (0.63 acres) will be restored at a 1:1 ratio. The herbaceous wetland community portion (0.26 acres) will be restored at a 0.5:1 ratio within the 30-foot wide aerial utility corridor . 5.0 Project Schedule Construction phasing of this project will begin with utility relocations then bridge replacement. The existing bridge will remain in service during the construction of the replacement bridges. The on-site mitigation work will begin upon completion of the bridge replacements. Permit drawings are attached. The Construction Date is May 1, 2014. 6.0 SEPA documentation Information included in this introduction letter, along with attachments is intended to supply documentation necessary to meet the requirements of the State Environmental Policy Act. Bridge Nos. 16 and 20 are located on NC 211. NC 211 is used for through traffic which connects US 17 and US 74, for a total of 24 miles, which takes approximately 26 minutes. A total of four alternatives were studied for replacing Bridge Nos. 16 and 20 in Brunswick County. These alternatives are described as follows:  Alternate 1 - Replace both bridges on existing alignment,  Alternate 2 - Replace Bridge No. 20 on new alignment while replacing Bridge No. 16 on existing alignment using an on-site detour,  Alternate 3 - Replacing both bridges on new alignment to the east of existing roadway, and 3  Alternate 4 - Replacing both bridges on new alignment to the west of existing roadway. Alternate 1 NCDOT Guidelines for Evaluation of Offsite Detours for Bridge Replacement Projects considers multiple project variables beginning with the additional time traveled by the average road user resulting from the offsite detour. The eastern loop for the offsite detour for this project would include continuing on US 17 to NC 87 to US 74 for a total of 41.4 miles, which would take approximately 43 minutes. The detour for the average road user would result in approximately 20 minutes additional travel time and approximately 18 miles additional travel. Up to a 6-month duration of construction is expected on this project. Based on the Guidelines, the criteria above indicate that a delay of 20 minutes for the average road user over a 6 month period is unacceptable. Brunswick County Emergency Services has also indicated that an offsite detour is unacceptable. While project costs and environmental impacts will be higher, maintenance of traffic onsite during construction is mandatory. NCDOT Division 3 concurs in these recommendations. Alternate 2 This alternative maintains existing traffic “on-site” and was initially supported by NCDOT as the best alternative to be implemented. However, after further study of the existing soils, it was determined that significant undercut would be required through adjacent wetlands resulting in permanent impacts not only along the new location alignment but also on the alignment for the temporary detour. Significant undercut and permanent impacts along a temporary facility was deemed “not feasible” which led to the study of Alternatives 3 and 4 which locates the roadway on new location adjacent to the existing bridges. Permanent wetland impacts for this alternative are 1.1 ac. Alternative 3 This alternative maintains existing traffic “on-site” and replaces both Bridge Nos. 16 and 20 on new alignment just east of existing roadway. The new alignment in the area of Bridge No. 20 is identical to Alternative 2. Permanent wetland impacts for this alternative are 0.76 ac. Alternative 4 This alternative maintains existing traffic “on-site” and replaces both Bridge Nos. 16 and 20 are on new alignment just west of existing roadway. The alignment for this alternative is approximately 180’ longer than Alternative 3 due to connection to existing alignment on the inside of a horizontal curve to the south. Permanent wetland impacts for this alternative are 0.95 ac. 4 Alternatives 3 and Alternative 4 are very similar alignments and have very similar impacts to the environment. However, Alternative 3 was chosen for implementation because of the following: • 0.19 ac. less wetland impacts, • 180’ shorter project length, • Less required undercut, and • Less utility impacts. 6.1 Independent Utility State Project 17BP.3.R.26 is in compliance with 23 CFR Part 771.111(f) which lists the FHWA characteristics of the independent utility of a project. The project meets the criteria for independent utility as discussed below:  The project has logical termini and independent utility and is of sufficient length to address environmental matters on a broad scope;  The project is usable and a reasonable expenditure of funds, even if no additional transportation improvements are made in the area; and  The project does not restrict consideration of alternatives for other reasonably foreseeable transportation improvements. 7.0 Resource Status The project is located in the Lumber River Basin and lies within Hydrologic Unit 030400206 (Subbasin 03-07-57). This is within the Middle Atlantic Coastal Plain ecoregion. 7.1 Wetland Delineations Wetland delineations for the study area were performed on September 07, 2011 by NCDOT staff members Lance Fontaine, John Merritt and Chris Underwood. The wetlands within the study area were delineated based on the 1987 U.S. Army Corps of Engineers (USACE) Wetland Delineation Manual (Atlantic and Gulf Coastal Plain Supplement) and a preliminary design was prepared to avoid and minimize impacts to wetlands to the maximum extent possible. This delineation was later field verified by Mr. Brad Shaver (USACE, Wilmington District) on April 17, 2013. The study area was revisited by Stoney Mathis (NCDOT), Hal Bain (RK&K), Pete Stafford (RK&K) and Audrey Burnette (RK&K) on November 04, 2013. 7.2 Stream Delineations Data collected for streams were derived from USGS topographic maps, the Brunswick County Soil Survey (USDA, 1990), and site reconnaissance. The data included stream classifications, which are presented in the attached documentation. A stream characterization and delineation was conducted by Hal Bain (RK&K) and Pete Stafford (RK&K) on November 04, 2013. A previous site visit to confirm the presence of jurisdictional streams within the project study area was conducted by Stoney Mathis (NCDOT), Brad Shaver (USACE Wilmington District) and Mason Herndon (NCDWR) on April 17, 2013. 5 7.3 Characterization of Jurisdictional Sites 7.3.1 Wetlands There is approximately 2.41 acres of wetlands within the project area. There is one wetland community found within the project study area. Field investigations conducted on September 07, 2011 and revisited on November 04, 2013 identified one wetland community (Riverine Swamp Forest) found within the project study area. This community dominates the project study area and generally begins at the toe of the existing roadway fill section. Information about this wetland complex can be found in the attachments to this letter report which includes a vicinity map, USACE wetland data forms and preliminary design plans depicting the extent of the wetlands within the project study area. 7.3.2 Streams There is approximately 177 linear feet of stream within the project area. Best Usage Classification for the jurisdictional stream, Honey Island Swamp, is C & Sw (Swamp Waters). Neither High Quality Waters (HQW), Water Supplies (WS-I: undeveloped watersheds or WS-II: predominately undeveloped watersheds), nor Outstanding Resource Waters (ORW) occur within 1.0 mile of the project study area. The two stream segments are not designated as a North Carolina Natural or Scenic River, or as a National Wild and Scenic River. Honey Island Swamp is not listed on the Final 2012 Section 303(d) list of impaired waters. 7.4 Impacts to Jurisdictional Resources Impacts to jurisdictional wetlands for State Project 17BP.3.R.26 are summarized below: Permanent Impacts: Proposed permanent impacts for the replacement of Bridge Nos. 16 and 20 include fill in wetlands, mechanized clearing in wetlands and conversion of forested wetland to shrub/herb wetland, totaling 0.76 acres of riparian wetlands. Temporary Impacts: There will be 0.01 acres of temporary hand-clearing at the bridges in jurisdictional wetlands due to project construction. Utility Impacts: There will be 0.21 acres of temporary impacts (by hand clearing) to jurisdictional wetlands as a result of aerial utility relocation. There will be 0.04 acres of forested wetlands that will be converted to herbaceous wetlands that will permanently impact the wetland community. The underground telephone and fiber optic cables will be relocated to the aerial joint use power poles, upon excavation for the on-site wetland restoration. It is anticipated that no impacts to streams will result from project construction. 6 8.0 Protected Species Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended, or by provisions of the Bald and Golden Eagle Act (BGPA). The United States Fish and Wildlife Service (USFWS, 2013) lists 15 federally protected species for Brunswick County as of the November 18, 2013 listing (Table 1). Table 1 Federally Protected Species in Brunswick County Common Name Scientific Name Federal Status* Habitat Present Biological Conclusion American alligator Alligator mississippiensis T (S/A) Yes N/A Atlantic sturgeon Acipenser oxyrinchus oxyrinchus E No No Effect Bald eagle Haliaeetus leucocephalus BGPA No No Effect Green sea turtle Chelonia mydas T No No Effect Kemp’s ridley sea turtle Lepidochelys kempii E No No Effect Leatherback sea turtle Dermochelys coriacea E No No Effect Loggerhead sea turtle Caretta caretta T No No Effect Piping plover Charadrius melodus T No No Effect Red-cockaded woodpecker Picoides borealis E No No Effect Shortnose sturgeon Acipenser brevirostrum E No No Effect West Indian manatee Trichechus manatus E No No Effect Wood stork Mycteria americana E No No Effect Cooley’s meadowrue Thalictrum cooleyi E No No Effect Rough-leaved loosestrife Lysimachia asperulaefolia E No No Effect Seabeach amaranth Amaranthus pumilus T No No Effect * BGPA = Bald and Golden Eagle Protection Act, E = Endangered, T = Threatened, T(S/A) = Threatened (Similarity of Appearance) The NC Natural Heritage Program (NCNHP) database (updated November 2013) was also reviewed for recorded occurrences of protected species. No occurrences of federally protected species were recorded within one mile for the project study area. Comments received from the USFWS dated September 15, 2011 are included in the attachments to this package. 7 8.1 Bald and Golden Eagle Protection Act (BGPA) In the July 9, 2007 Federal Register (72:37346-37372), the bald eagle was declared recovered, and removed (de-listed) from the Federal List of Threatened and Endangered Wildlife. This delisting took effect August 8, 2007. After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) became the primary law protecting bald eagles. No nesting and/or foraging habitat for the bald eagle is present within the project study area or within 660 feet of the project study area. 8.2 Moratorium There is no in-water work moratorium recommended for State Project 17BP.3.R.26. The communication with the North Carolina Wildlife Resources Commission (Travis Wilson) is included as an attachment to this package. 9.0 Cultural Resources The potential effect of the proposed project on cultural resources in the project area was evaluated in accordance with Section 106 of the National Historic Preservation Act of 1966, as amended. NCDOT Historic Architecture staff communications, dated November 20, 2013 determined that replacement of the existing structures (Bridge Nos. 16 and 20) will Not Adversely Impact any historic buildings or landscapes. The referenced communications are included as attachments to this package. An archaeological survey of the project’s Area of Potential Effect (APE) was conducted by NCDOT archaeologists to determine the project’s impact on significant archaeological or historical resources. NCDOT Archaeological staff communications, dated November 06, 2013 indicate that no archaeological sites were found within the project’s APE. Therefore, no additional archaeological investigation is recommended for this project. The referenced communications are included as attachments to this package. 10.0 FEMA Compliance Honey Island Swamp is a FEMA regulated stream. Bridge Nos. 16 and 20 can be found on FIRM maps 37201184 and 37201186, dated June 2, 2006. The replacement of these bridges produced a 0.01 foot increase in the water surface elevation between the Revised Model and the Corrected Effective Model just downstream of the bridge. No existing structures are impacted by this increase. This increase is categorized as a Type 2D MOA, which is a category within the Memorandum of Agreement (MOA) between NCDOT and Floodplain Mapping. This increase has already been approved by the appropriate state and local officials as well as the Federal Emergency Management Agency (FEMA) to assure compliance with federal, state, and local floodway regulations. 8 11.0 Mitigation Options The NCDOT has investigated potential on-site wetland mitigation opportunities. However, if on- site mitigation is not feasible, mitigation will be provided by the North Carolina Department of Environment and Natural Resources Ecosystem Enhancement Program (NCEEP). In accordance with the Memorandum of Agreement dated July 22, 2003 between NCDOT and U.S. Army Corps of Engineers, the NCEEP may provide off-site mitigation to satisfy the Federal Clean Water Act compensatory mitigation requirements for this project. Permanent impacts to jurisdictional wetlands totaling 0.76 acres of Riverine Swamp Forest (NCWAM wetland type) will occur as a result of project construction adjacent to the existing roadway/bridge location. NCDOT plans to provide (0.76 acres) on-site replacement (restoration) by removal of the existing roadway bed and roadway fill down to the natural wetland elevation. Replanting with species dominant in the adjacent Riverine Swamp Forest (Honey Island Swamp) will be conducted in these areas. It is anticipated that three years of visual monitoring of vegetation will be conducted. 11.1 Avoidance and Minimization All jurisdictional features were delineated, field verified and surveyed within the corridor for the NC 211 bridge replacements. Using these surveyed features, preliminary designs were adjusted to avoid and/or minimize impacts to jurisdictional areas. NCDOT employs many strategies to avoid and minimize impacts to jurisdictional areas in all of its designs. Many of these strategies have been incorporated into BMP documents that have been reviewed and approved by the resource agencies and which will be followed throughout construction. Individual avoidance and minimization items are as follows:  No staging of construction equipment or storage of construction supplies will be allowed in wetlands or near surface waters.  The project was designed to avoid or minimize disturbance to aquatic life movements by use of single span bridges. The spans were maximized while maintaining the same vertical clearances as the existing bridges. There are no deck drains. The bridge runoff is collected at the low point of the bridge and discharges outside of the jurisdictional waters. A rip rap pad was used to diffuse the velocities before entering the wetlands at the pipe outlet for the drainage structure at Bridge No. 20. A preformed scour hole was used to diffuse the velocities before entering the wetlands at the pipe outlet for the drainage structure at Bridge No. 16.  NCDOT will minimize long-term water quality impacts through the use of the most recent Best Management Practices for Protection of Surface Waters, as identified in the Federal Aid Highway Program (FHPM) and North Carolina Administrative Code, Chapter 4.  NCDOT and its contractors will not excavate, fill, or perform land clearing activities within Waters of the U.S. or any areas under the jurisdiction of the USACE, except as authorized by the USACE. To ensure that all borrow and waste activities occur on high ground, except as authorized by permit, the NCDOT shall require its contractors to identify all areas to be used to borrow material, or to dispose of dredged, fill or waste material. Documentation of the 9 location and characteristics of all borrow and disposal sites associated with the project will be available to the USACE on request.  The use of 2:1 fill slopes in jurisdictional areas where practicable.  NCDOT will implement Best Management Practices for Bridge Demolition and Removal. The asphalt-wearing surface of the two bridges and bridge rails will be removed without dropping them into the water prior to bridge demolition.  Turbidity curtains will be installed around existing interior bents prior to extraction of the steel piles. The timber piles encased in concrete will be cut at the streambed and pulled out with a crane. Silt fence and coir fiber wattle barrier will be used during construction to prevent sediment from entering the wetlands and jurisdictional waters.  Utilize existing aerial power poles where practical, thus reducing the extent of a new utility corridor.  The use of hand clearing rather than mechanized clearing where possible.  High visibility fencing will be utilized to identify environmentally sensitive areas that are not to be impacted. 11.2 Compensation Although NCEEP is available for mitigation by compensation, there are on-site opportunities available. See Section 11.0 Mitigation Options for more information. 12.0 Indirect and Cumulative Effects Information associated with the subject project study area revealed that no significant impacts to natural, ecological, cultural, scenic, or community resources are expected due to the construction of the subject project. Any direct impacts to resources have been avoided (where possible), minimized, and mitigated. The bridges are being replaced immediately upstream of the existing structures and these replacements are not creating any new development access to adjacent land or offering any significant travel time savings. Therefore, no indirect or cumulative effects are expected due to the construction of State Project 17BP.3.R.26. 13.0 Regulatory Approvals Section 404: Application is hereby made for a USACE Individual 404 Permit as required for the above-described activities. Section 401: We are also requesting a Section 401 Water Quality Certification from the NCDWR. In compliance with Section 143-215.3D(e) of the NCAC, we will provide $570.00 to act as payment for processing the Section 401 permit application previously noted in this application (see Subject line). We are providing electronic copies of this application package to Mason Herndon and Sonia Carrillo (NCDWR), for their approval. CAMA Consistency Determination: A Federal Consistency Determination letter will be submitted along with project information to Steve Sollod (NCDCM reviewer). 10 If you have any questions or need additional information, please contact Stonewall D.

Honey Island Swamp is not listed on the Final 2012 Section 303(d) list of impaired waters. 6 7.4 Impacts to Jurisdictional Resources Impacts to jurisdictional wetlands for State Project 17BP.3.R.26 are summarized below: Permanent Impacts: Proposed permanent impacts for the replacement of Bridge Nos. 16 and 20 include fill in wetlands, mechanized clearing in wetlands and conversion of forested wetland to shrub/herb wetland, totaling 0.76 acres of riparian wetlands. Temporary Impacts: There will be 0.01 acres of temporary hand-clearing at the bridges in jurisdictional wetlands due to project construction. Utility Impacts: There will be 0.21 acres of temporary impacts (by hand clearing) to jurisdictional wetlands as a result of aerial utility relocation. There will be 0.04 acres of forested wetlands that will be converted to herbaceous wetlands that will permanently impact the wetland community. The underground telephone and fiber optic cables will be relocated to the aerial joint use power poles, upon excavation for the on-site wetland restoration. It is anticipated that no impacts to streams will result from project construction. 8.0 Protected Species Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed Endangered (PE), and Proposed Threatened (PT) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended, or by provisions of the Bald and Golden Eagle Act (BGPA). The United States Fish and Wildlife Service (USFWS, 2013) lists 15 federally protected species for Brunswick County as of the November 18, 2013 listing (Table 1).

No occurrences of federally protected species were recorded within one mile for the project study area. Comments received from the USFWS dated September 15, 2011 are included in the attachments to this package. 8.1 Bald and Golden Eagle Protection Act (BGPA) In the July 9, 2007 Federal Register (72:37346-37372), the bald eagle was declared recovered, and removed (de-listed) from the Federal List of Threatened and Endangered Wildlife. This delisting took effect August 8, 2007. After delisting, the Bald and Golden Eagle Protection Act (Eagle Act) (16 U.S.C. 668-668d) became the primary law protecting bald eagles. No nesting and/or foraging habitat for the bald eagle is present within the project study area or within 660 feet of the project study area. 8.2 Moratorium There is no in-water work moratorium recommended for State Project 17BP.3.R.26. The communication with the North Carolina Wildlife Resources Commission (Travis Wilson) is included as an attachment to this package. 9.0 Cultural Resources The potential effect of the proposed project on cultural resources in the project area was evaluated in accordance with Section 106 of the National Historic Preservation Act of 1966, as amended. NCDOT Historic Architecture staff communications, dated November 20, 2013 determined that replacement of the existing structures (Bridge Nos. 16 and 20) will Not Adversely Impact any historic buildings or landscapes. The referenced communications are included as attachments to this package. 8 An archaeological survey of the project’s Area of Potential Effect (APE) was conducted by NCDOT archaeologists to determine the project’s impact on significant archaeological or historical resources. NCDOT Archaeological staff communications, dated November 06, 2013 indicate that no archaeological sites were found within the project’s APE. Therefore, no additional archaeological investigation is recommended for this project. The referenced communications are included as attachments to this package. 10.0 FEMA Compliance Honey Island Swamp is a FEMA regulated stream. Bridge Nos. 16 and 20 can be found on FIRM maps 37201184 and 37201186, dated June 2, 2006. The replacement of these bridges produced a 0.01 foot increase in the water surface elevation between the Revised Model and the Corrected Effective Model just downstream of the bridge. No existing structures are impacted by this increase. This increase is categorized as a Type 2D MOA, which is a category within the Memorandum of Agreement (MOA) between NCDOT and Floodplain Mapping. This increase has already been approved by the appropriate state and local officials as well as the Federal Emergency Management Agency (FEMA) to assure compliance with federal, state, and local floodway regulations. 11.0 Mitigation Options The NCDOT has investigated potential on-site wetland mitigation opportunities. However, if on- site mitigation is not feasible, mitigation will be provided by the North Carolina Department of Environment and Natural Resources Ecosystem Enhancement Program (NCEEP). In accordance with the Memorandum of Agreement dated July 22, 2003 between NCDOT and U.S. Army Corps of Engineers, the NCEEP may provide off-site mitigation to satisfy the Federal Clean Water Act compensatory mitigation requirements for this project. Permanent impacts to jurisdictional wetlands totaling 0.76 acres of Riverine Swamp Forest (NCWAM wetland type) will occur as a result of project construction adjacent to the existing roadway/bridge location. NCDOT plans to provide (0.76 acres) on-site replacement (restoration) by removal of the existing roadway bed and roadway fill down to the natural wetland elevation. Replanting with species dominant in the adjacent Riverine Swamp Forest (Honey Island Swamp) will be conducted in these areas. It is anticipated that three years of visual monitoring of vegetation will be conducted. 11.1 Avoidance and Minimization All jurisdictional features were delineated, field verified and surveyed within the corridor for the NC 211 bridge replacements. Using these surveyed features, preliminary designs were adjusted to avoid and/or minimize impacts to jurisdictional areas. NCDOT employs many strategies to avoid and minimize impacts to jurisdictional areas in all of its designs. Many of these strategies have been incorporated into BMP documents that have been reviewed and approved by the resource agencies and which will be followed throughout construction. Individual avoidance and minimization items are as follows: 9  No staging of construction equipment or storage of construction supplies will be allowed in wetlands or near surface waters.  The project was designed to avoid or minimize disturbance to aquatic life movements by use of single span bridges. The spans were maximized while maintaining the same vertical clearances as the existing bridges. There are no deck drains. The bridge runoff is collected at the low point of the bridge and discharges outside of the jurisdictional waters. A rip rap pad was used to diffuse the velocities before entering the wetlands at the pipe outlet for the drainage structure at Bridge No. 20. A preformed scour hole was used to diffuse the velocities before entering the wetlands at the pipe outlet for the drainage structure at Bridge No. 16.  NCDOT will minimize long-term water quality impacts through the use of the most recent Best Management Practices for Protection of Surface Waters, as identified in the Federal Aid Highway Program (FHPM) and North Carolina Administrative Code, Chapter 4.  NCDOT and its contractors will not excavate, fill, or perform land clearing activities within Waters of the U.S. or any areas under the jurisdiction of the USACE, except as authorized by the USACE. To ensure that all borrow and waste activities occur on high ground, except as authorized by permit, the NCDOT shall require its contractors to identify all areas to be used to borrow material, or to dispose of dredged, fill or waste material. Documentation of the location and characteristics of all borrow and disposal sites associated with the project will be available to the USACE on request.  The use of 2:1 fill slopes in jurisdictional areas where practicable.  NCDOT will implement Best Management Practices for Bridge Demolition and Removal. The asphalt-wearing surface of the two bridges and bridge rails will be removed without dropping them into the water prior to bridge demolition.  Turbidity curtains will be installed around existing interior bents prior to extraction of the steel piles. The timber piles encased in concrete will be cut at the streambed and pulled out with a crane. Silt fence and coir fiber wattle barrier will be used during construction to prevent sediment from entering the wetlands and jurisdictional waters.  Utilize existing aerial power poles where practical, thus reducing the extent of a new utility corridor.  The use of hand clearing rather than mechanized clearing where possible.  High visibility fencing will be utilized to identify environmentally sensitive areas that are not to be impacted. 11.2 Compensation Although NCEEP is available for mitigation by compensation, there are on-site opportunities available. See Section 11.0 Mitigation Options for more information. 10 12.0 Indirect and Cumulative Effects Information associated with the subject project study area revealed that no significant impacts to natural, ecological, cultural, scenic, or community resources are expected due to the construction of the subject project. Any direct impacts to resources have been avoided (where possible), minimized, and mitigated. The bridges are being replaced immediately upstream of the existing structures and these replacements are not creating any new development access to adjacent land or offering any significant travel time savings. Therefore, no indirect or cumulative effects are expected due to the construction of State Project 17BP.3.R.26. 13.0 Other Permits In addition to the DCM Consistency Determination for State Project 17BP.3.R.26, permits to be obtained include an Individual 404 permit, an Individual 401 Water Quality Certification, and a State Stormwater permit. (applications scheduled to be submitted in December 2013) 14.0 Division of Coastal Management (DCM) General Policy Guidelines for the Coastal Area The general policy guidelines in 15A NCAC 07 have been reviewed for applicability to this project in its entirety. State Project 17BP.3.R.26 will not impact any AECs. Specifically, the .0700 rules (mitigation), and the .0800 rules (water quality) were reviewed for compliance for State Project 17BP.3.R.26. This project will not affect shoreline erosion or shoreline access. However, this project will require compensatory mitigation and impact water quality. The project has been designed to avoid and minimize jurisdictional areas to the largest extent practical. Best Management Practices will be in place during construction; mitigation will be accomplished through on-site opportunities (restoration of riverine swamp forest by removal of existing roadway fill along with replanting). If NCDOT determines that on-site restoration opportunities are not viable then, in-lieu fee compensatory mitigation will be provided through NCEEP. 15.0 Brunswick County Multi-Jurisdictional CAMA Core Land Use Plan The Brunswick County Multi-Jurisdictional CAMA Core Land Use Plan (adopted in 2007) was reviewed for policies and statements that would pertain to this project. The purpose and need for this project is stated in Section 1.0 of this document. Please refer to Section 12.0 for indirect and cumulative effects. The Brunswick County Vision Statement (section 4, page 5) of the Brunswick County Multi- Jurisdictional CAMA Core Land Use Plan (2007) states: "Brunswick County shall seek to preserve and enhance its natural and human resources. The County will plan for and accommodate future growth while simultaneously maintaining the quality of life for current and future residents. Brunswick County will pursue accomplishment of the following mission statements: 11 • Set high standards for responsible, well managed growth, and guide development patterns through comprehensive planning and community involvement. • Develop a high degree of cooperation among County government and municipal governments and citizens. • Promote quality education and lifelong learning opportunities in Brunswick County. • Identify goals and propose strategies for the development of new businesses and industries, agribusinesses, seafood products, tourism, and recreational and retirement areas in all parts of the County. • Provide an infrastructure system that meets the present and future needs of its citizens, supports a vibrant economy, protects the environment, and adds to the overall quality of life. • Provide county-wide services that enhance the health, safety, and quality of life for Brunswick County citizens. • Enable Brunswick County residents to meet their needs for food, clean water, clothing, housing, employment, health care, and life enrichment activities." The Brunswick County Multi-Jurisdictional CAMA Core Land Use Plan also states (Section 5, pageI 07) Brunswick County was the fourth fastest growing county in North Carolina between 2000 and2005. "The significant population growth translates into significant land development. The County is concerned about inadequate roads to accommodate this growth. It is critical that the County work with the state to plan for road improvements, the proper size and location of future roads, and funding options." The plan also states (Section 6, page 45) Brunswick County will undertake actions to support maintenance of safe hurricane evacuation routes. State Project 17BP.3.R.26 is to preserve the mobility and safety of the traveling public by replacing the existing 59-year old structurally deficient bridges that can no longer be addressed by maintenance activities. Based on the information stated above, NCDOT concludes that this project is consistent with the Brunswick County Multi-Jurisdictional CAMA Core Land Use Plan (2007).
