The Corps evaluates this application and decides whether to issue, conditionally issue, or deny the proposed work pursuant to applicable procedures of the following Statutory Authorities:

 Section 404 of the Clean Water Act (33 U.S.C. 1344)

 Section 10 of the Rivers and Harbors Act of 1899 (33 U.S.C. 403)


 Location Description:

 Nearest Town: Topsail Beach            

Nearest Waterway:     New Topsail Inlet     

River Basin:    Onslow Bay

Latitude and Longitude: 34.3694 N, -77.625 W

Existing Site Conditions

The project area is located on the southern end of Topsail Island, a barrier island located in southeast North Carolina, within the Town limits of Topsail Beach and also located in Topsail Inlet and various federal navigation channels located in between the Atlantic Intracoastal Waterway (AIWW) and Topsail Island.

Applicant’s Stated Purpose

The applicants stated purpose is to obtain beach compatible sand in a cost-effective manner and to maintain the originally designed beach fill project, protecting property and public infrastructure within the Town of Topsail Beach, and to maintain the navigational channels surrounding Topsail Beach.  

Project Description

The Town of Topsail Beach is planning to dredge: (1) approximately 5,000‐linear feet of the southern extent of Topsail Creek, (2) approximately 8,500‐linear feet of New Topsail Inlet from Topsail Creek to the mouth of the inlet at the ebb shoals (3) the approximately 3,700‐linear foot Banks Connector Channel between New Topsail Inlet and Banks Channel, (4) a 2,000‐linear foot cut through channel between Topsail Creek and Banks channel, (5) shoaled areas within Banks Channel along the approximately 28,300‐linear feet adjacent to the Town and (6) the two Banks Side Channels which provide homeowners access to Banks Channel within Town limits.

The project will further expand the dredge template beyond the previously permitted channel widths in sections of New Topsail Inlet, Banks Connector Channel, and Banks Channel. Topsail Creek would remain at the currently permitted 150’ width, aside from a widener at the confluence of the Cut Through Channel. New Topsail Inlet would widen from 150’ to 500’ wide from the seaward edge of the ebb shoal to the confluence of Banks Connector Channel and would then narrow to the currently permitted width of 150’. Banks Connector Channel would increase from 150’ to 300’ wide on its western end, near the confluence of New Topsail Inlet but would remain at its currently permitted 150’ width from station 0+00 (at the confluence with Banks Channel) to station 16+50. The Cut Through Channel will be added to the navigational channels to aid in safe navigation for small vessels from Topsail Creek to Banks Channel and will be wide enough for boats to safely pass each other while underway. Banks Channel would widen from the federally authorized 80’ to 200’ wide as well as deepened from the federally authorized 7+2’ to 12+2’ MLW depth. Proposed dredging would follow the centerline of the channel system previously dredged in 2013/2014, which established fixed channel positions rather than following the deep water channel. The centerline of Topsail Inlet has been shifted slightly south from the previous project to  reflect a more shore normal alignment and coincide with the current orientation of the Inlet system. The proposed dredging is summarized in the following Table 1 below.

This project proposes adaptive management of the channel system seeking to contribute to the success of the previous project by extending the time period between dredge work. The capacity created during the 2013 project maintained sufficient navigable water for all neighboring channels for 3 years, however the long term goal is to achieve a 5 year project lifespan, which is anticipated to be gained from this iteration of the management plan. This allows for robust environmental rebound for coastal organisms between projects—again building on the successful biological rebound of all monitored species since the previous job. As such, all proposed dredging would be conducted from November 16, 2018 to March 31, 2019 in order to avoid times of peak biologic activity. A hydraulic or cutter head suction dredge would be used.

The proposed beach fill consists of placing 1.5 million cubic yards of sand along the oceanfront shoreline of Topsail Beach. Re-nourishment operations will occur along the 24,700‐lft of beach, the same area as previous projects, extending from approximately 1,000‐ft south of Goodwin Avenue to approximately 2,000‐ft north of the Town limits. All beach fill will be placed within the 30‐year easement secured and utilized during the winter 2011 beach nourishment event.

This project will bring the Town’s project to the specifications of their adapted 30‐Year Management Plan and provide a level of protection consistent with the coastal storm damage reduction project as designed by the USACE. A full main frontal dune will be constructed in front of the existing dune system, at an elevation of 12’ NAVD88 and with a dune crest width of 25‐linear feet. The previously built beach berm width, averaging 120 feet will be constructed seaward of the dune to a height of 5‐ft (NAVD88) with a 1:20 fill slope extending from the water ward edge of the berm to the intertidal zone of the beach. Included in the 23,576‐lft is an approximately 500‐lft transitional zone or fill taper from Goodwin Avenue south and an approximately 500‐lft transitional zone or northern fill taper ending just beyond Town limits. Around the Jolly Roger fishing pier, dune construction will continue, however there will be no berm construction directly adjacent to the pier structure.

While 1.5 million CY of sand is required to fill the design template, the proposed channel alignments contain 3.2 million CY of beach quality sand. The proposed project intends to only dredge the volume needed to fill the beach fill template of 1.5 million CY. This represents approximately half of the total available sediment within the channel dredging templates. Work for this project will focus on the problematic shoaling areas of New Topsail Inlet, Banks Connector Channel, Topsail Creek, and the Cut Through Channel. The remaining volume of sand, existing primarily in Banks Channel, will be left as a contingency plan for future or emergency nourishment projects.

 Avoidance and Minimization

The applicant provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment: The applicant states that the proposal will reduce the frequency of maintenance dredging and deposition along the beach, which will reduce the disruption of bottom habitat and the upland, intertidal, and submerged beach.

Before the Interim Project initiated construction in 2009, the side cast dredge was working in New Topsail Inlet and Topsail Creek an average of 4 times per year and the AIWW Inlet Crossings at Topsail Creek, and Howards Channel were dredged an average of every other year. The material dredged from the AIWW crossings was often placed on the oceanfront shoreline of Topsail Beach, impacting the upland, intertidal and submerged beach every other year. The Federal 50‐Year Plan has a return period of 4 years between work, but does not include a navigation component. The Federal Project utilizes offshore borrow areas as a sand source, therefore requiring separate attention to remove shoaling from the channel system. As such, the side cast dredge would most likely be used to fulfill this requirement, returning to its 3‐4 projects per year cycle.

Additionally, the applicant proposes to conduct dredging from November 16, 2018 to March 31, 2019 in order to avoid times of peak biologic activity.

Compensatory Mitigation

The applicant offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment: The applicant does not propose to provide any compensatory mitigation.

Essential Fish Habitat

Pursuant to the Magnuson-Stevens Fishery Conservation and Management Act, this Public Notice initiates the Essential Fish Habitat (EFH) consultation requirements. The Corps’ initial determination is that the proposed project may adversely affect EFH or associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management Councils or the National Marine Fisheries Service.

Cultural Resources

Pursuant to Section 106 of the National Historic Preservation Act of 1966, Appendix C of 33 CFR Part 325, and the 2005 Revised Interim Guidance for Implementing Appendix C, the District Engineer consulted district files and records and the latest published version of the National Register of Historic Places and initially determines that:

No historic properties, nor properties eligible for inclusion in the National Register, are present within the Corps’ permit area; therefore, there will be no historic properties affected.  The Corps subsequently requests concurrence from the SHPO (or THPO).

The District Engineer’s final eligibility and effect determination will be based upon coordination with the SHPO and/or THPO, as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on historic properties within the Corps-indentified permit area.

Endangered Species

Pursuant to the Endangered Species Act of 1973, the Corps reviewed the project area, examined all information provided by the applicant and consulted the latest North Carolina Natural Heritage Database. Based on available information:

The Corps determines that the proposed project  may affect federally listed endangered or threatened species or their formally designated critical habitat.

The Corps will consult under Section 7 of the ESA and will not make a permit decision until the consultation process is complete.
