Town of Sunset Beach, Jinks Creek c/o Moffat & Nichol Major Mod. Page 2 9. PROJECT DESCRIPTION: This is a second major modification request to State Permit No. 79-19. The project area is the Bay Area between 1503 & 1711 Canal Drive and between 18' street to the Inlet, the end of Cobia Street and the end of Seaside Drive on the mainland, Brunswick County. The new proposed channel realignment extends the Bay Area primary channel by approximately 200 ft. along the southern shoreline and adds a secondary channel along the northern shoreline. The new proposal would add 0.3 acres of open water impact and increase the dredge volume by approximately 4,700 cubic yards. Both channels are proposed to be excavated to — 6 ft. MLW (- 5 +1). Two offload sites are proposed with temporary structures. One is located at the end of Cobia Street adjacent to the Feeder Channel on Sunset Beach and the other is at the end of Seaside Drive on the mainland adjacent to the AIW W and north of Jinks Creek. The original project area is on the eastern end of Sunset Beach between the island and Tubbs Inlet. The project is comprised of man- made canals that connect to a Feeder Channel and a Bay Area to the south. Both the Feeder Channel and the Bay Area connect to South Jinks Creek. The shoreline of the Finger Canals is stabilized primarily by bulkheads, with some sections of riprap. The man-made canals border narrow residential lots heavily developed with single family residences and private docking facilities. The width of the canals is approximately 90 ft. and there are areas of oysters and coastal wetlands, mostly consisting of Salt Marsh Cordgrass (Spartina alternii lora), established along the 3,200 linear ft. project area. The 3,500 linear ft. Feeder Channel project area is stabilized by bulkheads with undeveloped lots to the north. To the south, the Bay Area is stabilized primarily by bulkheads, with some rip rap and sparse vegetation including Sea Oxeye and Salt Marsh Cordgrass. The Bay Area project extends 2,200 linear ft. to the east with widths ranging from 130 ft. in with to 470 ft. nearest the confluence with Jinks Creek. Both the Feeder Channel and the Bay Area connect to the 1,700 linear ft. South Jinks Creek project to the east, which transitions into the Atlantic Ocean through Tubbs Inlet to the south and to the AI W W to the north. State Permit No. 79-19 was issued by CRC-VR-20-09 and Permit No. 79-19 was issued on March 3, 2020 for the excavation of the Finger Canals, Feeder Channel, Bay Area and South Jinks Creek with both upland disposal and beach fill. The depth of excavation was authorized to — 5 ft. below MLW for Finger Canals and to — 6 ft. below MLW for the Bay Area and South Jinks Creek. The dredging of the South Jinks Creek area was proposed to be dredged to a final depth of -6 ft. (- 5 Ft. + 1 ft. over dredge) at MLW in an area measuring approximately 1,750 ft. in length by 100 ft. in width for a total volume of 40,500 cubic yards of material. The proposed template had a 5:1 slope throughout the dredge footprint. A previous maintenance event of the Finger Canals and Feeder Channel was conducted under State Permit No. 45-02, which expired on December 31, 2005. The dredging event authorized the removal of 38,164 cubic yards with excavation to a depth of — 5.2 ft. at MLW, this was the first maintenance event for the feeder system since State Permit No. 211-85. A Major Modification was issued on 9/10/20 for a nearshore placement are seaward of Sunset Beach between 311 through 1311 streets. The placement of approximately 40,500 cubic yards within the nearshore area adjacent to Sunset Beach would impact up to 9.2 acres of coastal habitat within the project area. No work has been completed at this time. State Permit no. 79-19 is due to expire on 12/31/24. This application references a Sediment Analysis for the Re -aligned channel(See Narrative and Tab F), SPBO conservation measures (Tab L), an EFH and Biological Assessment (Tabs H and I), Manatee Avoidance Guidelines (Tab J) and NMFS Recommendations (Tab K). Most documents were submitted with the previous project proposal and are being re -submitted for the proposed Bay Area channel re -alignment. The applicant has also included the certified property notifications that were sent out to property owners that are closest to the proposed primary and secondary channels (see Attached documentation). Town of Sunset Beach, Jinks Creek c/o Moffat & Nichol Major Mod. Page 3 The area adjacent to the Bay Area is classified as Island Residential Sunset Beach Future Land Use Plan Map. The waters of the Bay Area are classified as SC by the Division of Water Resources. They ARE NOT designated as a Primary Nursery Area by (PNA) the N.C. Division of Marine Fisheries and they are CLOSED to shellfishing. 10. PROPOSED PROJECT: The applicant is proposing to re -align the primary channel and add a secondary channel within the Bay Area adjacent to the Town of Sunset Beach and install temporary structures at two offload sites. The project Narrative states that the proposed dredging project would change the authorized template for the Bay Area maintenance dredging in order to allow more local homeowners to access the channel from their individual docks. The original Bay Area footprint was a 2200 ft. long by 80 ft. wide channel that essentially went through the middle of the Bay Area connecting to South Jinks Creek. The proposed new alignment would result in two new channels, one primary channel along the southern Bay Area and one secondary channel along the northern Bay Area, from station 12+00 to station 24+00 (see Narrative and sheet C-102). The primary channel would be 1200 ft. long with a 30 ft. bottom cut extending up to a 55 ft. top cut with a 3:1 channel side slopes. The secondary channel would be 1000 ft. long with a 20 ft. bottom cut extending up to a 45 ft. top cut with a 3:1 channel side slopes. Both channels are proposed to be dredged to the original project depth of -6 ft. at MLW (-5+1). The channels would connect to South Jinks Creek which has an authorized project depth of -6 ft. at MLW. The new 2.3-acre impact increases slightly from the original alignment as does the dredge volume. According to the application, the dredge volume will increase from 12,200 CY to 16,894 CY within the Bay Area and the spoil will be placed in the previously permitted spoil site located at Georgetown Road. The application indicates that all dredging operations in this area would be conducted between October 1 and March 31s` and that a minimum 10 ft. buffer would be maintained from any Coastal Wetland Areas (see Tab G for Marsh boundaries). All work will be performed via bucket to barge. The application also contains a proposal to construct two temporary structures at two new offload sites to dispose of non -beach compatible materials. The primary offload site is at the end of Seaside Road along the AIW W on the mainland side across from North Jinks Creek (see Narrative, sheet S-502 and Tab N). This site would accommodate disposal barges and would require navigation through North Jinks Creek. The applicant has provided a hydrographic survey of North Jinks Creek (see Map No. 6 dated 9/16/20). A letter of objection was received by an adjacent riparian owner to the offload site, but no material is proposed to be stored onsite (see letter dated 9/9/21 from James and Danna Collins). This site is void of Coastal Wetlands, although there are wetlands present adjacent to the site. A temporary 100 ft. long by 24 ft. wide gabion filled offload ramp is proposed at this location for offloading which would impact approximately 2,400 sq. ft. of bottom habitat within Estuarine Waters and Public Trust Area. The ramp would be placed on a geotextile grip and filter fabric to limit vertical movement. The secondary offload site is at the end of Cobia street, which is located directly adjacent to the Feeder Canal north of the Bay Area (see Narrative and sheet S-501). There are no Coastal Wetlands adjacent to this street end. A temporary bulkhead is proposed, measuring 36 ft. long by 6 ft. wide, using #57 stone filled gabions waterward of the existing bulkhead to ensure that heavy equipment would not compromise the existing bulkhead. According to the application, the gabion filled wall would extend a maximum of 7 ft. waterward ofNHW and would be placed on a geotextile grid with filter fabric temporarily impacting up to 252 sq. ft. of Estuarine Waters and Public Trust Area. The proposal includes a shellfish relocation effort prior to bulkhead installation (see Attached Plan). All temporary structures would be relocated at project completion. Town of Sunset Beach, Jinks Creek c/o Moffat & Nichol Major Mod. Page 4 11. ANTICIPATED IMPACTS: The proposed excavation of approximately 16,894 cubic yards of material would disturb up to 2.3 acres of shallow bottom habitat within the project area expanding the previously authorized dredge footprint. The final project depth would be -6 ft. at MLW in the Bay Area, this would connect to — 6 ft. at MLW in S. Jinks, but would not connect to deeper water within greater Jinks Creek and Tubbs Inlet. The Town previously obtained CRC Variance No. CRC-VR-20-09 for the proposed maintenance dredging without a connection to deeper waters as required by rule 15A NCAC 711.0208 (b)(F). The impacts of both proposed offload sites would temporarily impact approximately 2,652 sq. ft. of bottom habitat outside of any Coastal Wetland Areas. Note: A Letter of Support for the project was received by DCM on 9/17/21 from Neal and Bren Harm and a Letter of Objection to the Offload site located at Seaside Road was received by DCM on 9/9/21. Both letters are included. Note: The last remaining property (the Mathers at 413 18th Street) continues to show "In Transit, Arriving Late" on the USPS tracking site (see attached). This is the second mailing (the first mailing went out on August 20`h, 2021) to the Mathers property that the Postal Service does not seem to be able to deliver. The applicant would like to respectfully request that DCM make a determination that they have made a good faith effort to notify this property owner, and therefore allow for processing of the application package to officially proceed.

Sunset Beach lies in Brunswick County, along the southern coastal border of North Carolina, adjacent to Ocean Isle Beach. The proposed project will occur along the eastern border of Sunset Beach, within the interior waters of Tubbs Inlet. Figure 1 shows the proposed project area in relation to Brunswick County.

The Town also requests authorization to construct a temporary offloading ramp at the terminus of Seaside Drive. Finally, authorization is requested to install a temporary bulkhead to aid in stabilizing the material offloading site at the previously authorized Cobia Street offloading site. The Town intends to offer both of these sites to the selected dredging contractor for their use. The contactor may choose either one or both of these sites for offloading. PROJECT PURPOSE AND NEED The previously permitted Bay Area channel helps to address the long-term erosion patterRIf(f IM recreational navigation access to the residential system. However, the previous alignment does not consider the unintended impacts of the additional dredging necessary for the local homeoXer2t3 2;j21 access the newly dredged channel from their individual docks. The proposed realignment strives to QCM WILMINGTON. NC Town of Sunset Beach Navigation Project Bay Area Realignment Project Narrative minimize the potential impacts of the additional dredging by considering a strategic channel design that addresses the long-term sediment infilling and residential access requirements. PROPOSED MODIFCATION Bay Area Dredge Template The currently permitted dredge template for the Bay Area currently extends through the approximate middle of the water body and terminates at the south Jinks Creek confluence with an 80-ft width. The modification request realigns the channel terminus from one (1) wide channel to two (2) narrower channels comprising of a primary and secondary navigation route. The primary channel extends along the southern Bay Area shoreline and maintains a 50-ft to 55-ft width (top cut), while the secondary channel follows the northern shoreline at a 40-ft to 45-ft width (top cut). The maximum dredge depth remains -6-ft MLW (-5+1) with 3:1 channel side slopes. Similar to the original alignment, the average depth in the Bay Area system will be increased from approximately -2-ft to -3-ft MLW to -6-ft (-5+1) MLW. Figure 2 shows a plan view comparison of the currently permitted alignment and the proposed realignment for the Bay Area and Tab E provides the permit drawings. The realignment extends the Bay Area primary channel by approximately 200-ft by following the southern shoreline until the template joins with south links Creek. Overall, the realignment initiates at station 12+00 from the original template and terminates at approximate station 24+00 in the south Jinks Creek confluence. The impact area for the original alignment equaled approximately 2.0 acres (86,277-ft2) and the realigned channel covers approximately 2.3 acres (101,176 ft2), inclusive of both the primary and secondary channels. As shown above, the dredge volume increased from 12,200 CY (original channel) to 16,894 CY with the new alignment. Figure 2.

(b) Bay Area Proposed Realignment Table 1 provides a summary of the proposed channel templates including the dredge volumes categorized for the primary and secondary channel. The modification request does not change the material placement site or dredging methodology. The Bay Area will be mechanically dredged with material placement occurring in an upland landfill facility. The dredging operations will be conducted between October 1" and March 31" to reduce the potential for environmental impacts. In addition, the dredge footprint will provide a minimum 10-ft buffer from any area of coastal wetland identified at the time of construction. These items are a few of the precautions proposed to help minimize the potential for environmental impacts on this project. Table 1— Dredge Template Description Existing Avg.

The material composition contains approximately 90%fines (>2300) and therefore is not compatible for beach placement. Tab F provides the sediment analysis results forthe realigned channel. RECEIVED AUG 23 - UPI DO WILMINGTON, NC Town of Sunset Beach Navigation Project Bay Area Realignment Project Narrative Spartina alterniflora exist along the intertidal and supratidal regions of the Feeder Channel and Bay Area. As shown in Tab G (Marsh Habitat Boundary), coastal wetlands have encroached within or close to the anticipated dredge area of the Bay Area but have not established near the Cobia Street terminus material off-loading site. Therefore, to minimize potential impacts to the marsh grass, no dredging will take place within 10 feet of any area of coastal wetlands. The 10-ft buffer should allow the channel adequate space to equilibrate without eroding the coastal marshes. During construction, the dredge equipment shall be prohibited from entering the buffer zone. Offloading Sites As was stated above, the Town intends to offer two offload sites to the chosen dredging contractor for their use. The contactor may choose to utilize either one or both of these sites for material offloading. Cobia Street - This contingency offload site will only be utilized if the primary offload site is unable to be utilized due to logistical consideration. A temporary bulkhead will be installed within the Feeder Channel at the terminus of Cobia Street (Figure 3). This temporary bulkhead will help to ensure that the existing bulkhead at this location will not be structurally compromised as a result of heavy equipment operation. The bulkhead will be comprised of a 36' by 6' gabion wall backfilled with a 36' by 1' placement of DOT #57 stone to stabilize the existing vinyl sheetpile wall. Figure 4 provides a ground level photograph of the existing sheetpile wall. The gabion filled structure will extend approximately 7-ft seaward of the existing wall and will be placed on a geotextile grid and filter fabric to limit vertical movement. All materials will be fully removed following project completion. Figure 3. Cobia Street Material Offloading Site RECEIVED AUG 23 ,-i ACM WILMINGTON, NC Town of Sunset Beach Navigation Project Bay Area Realignment Project Narrative Figure 4. Existing Vinyl Sheetpile Wall (Cobia Street) The gabion wall will be placed below MHW in the Feeder Channel. The footprint of the proposed gabion wall with backfill will be 252 sf. To minimize the potential for shellfish impacts, any shellfish within the footprint of the temporary structure will be relocated prior to the bulkhead installation. The shellfish relocation will be conducted in conjunction with the relocation efforts already required for the dredge footprint in the Feeder Channel. Seaside Road (Primary Offloading Site) —An offloading site will be constructed at the end of Seaside Road, along the Atlantic Intracoastal Waterway (See Figure 5). This offload site will handle non -beach compatible materials resulting from the dredging of the Bay Area, South links Creek, the feeder canal and finger canals. It is anticipated that disposal barges will be able to traverse North Jinks Creek at and around high tide. There is currently an unvegetated beach at the site (see Figure 6). In order to allow for land -based equipment to be able to access barges containing spoil material, a temporary 100' by 24' gabion offloading ramp will be constructed in this location. The temporary gabion ramp will be placed on a geotextile grid and filter fabric to limit vertical movement. All materials will be fully removed following project completion. The construction of the temporary gabion ramp will impact 2,400 sf of bottom habitat. No coastal wetlands will be filled by the construction of the temporary ramp.

Seaside Road Material Offloading Site ADDITIONAL ENVIRONMENTAL CONCERNS RECEIVED AUG 23 2021 ACM WILMINGTON, NC As part of the previously permitted components of this project, the applicant conducted studies to evaluate potential impacts to managed or endangered species that may occur as a result of the overall project. While these reports were completed as part of the original permit submittals, the findings should reasonably be expected to apply to the proposed realigned channel. Tab H provides an Essential Fish Habitat (EFH) assessment and Tab I provides a Biological Assessment (BA) for the project. Generally, the referenced reports support the project should not adversely impact any threatened or managed species. Additional precautions proposed for the maintenance project include following U.S. Fish and Town of Sunset Beach Navigation Project Bay Area Realignment Project Narrative Wildlife Service (USFWS) recommended guidelines for avoiding impacts to West Indian Manatee and recommendations provided by the National Marine Fisheries Service (NMFS) to help protect sea turtles and smalltooth sawfish. Tab J (Manatee Avoidance Guidelines) shows the manatee guidelines while Tab K (NMFS Recommendations) provides the sea turtle and smalltooth sawfish precautions. i11R1to] ilk] [in IS*06111Ct41:11►'l The applicant has also contacted the State Historic Preservation Office (SHPO) as part of the original permit submittals to inquire on any known historic resources in the area such as shipwrecks or archeological artifacts. These inquiries did not identify any known resources with the potential to be impacted by the project. Tab L (SHPO Resource Review) provides the written response from SHPO. It is again reasonably expected that these findings may be also be applied to proposed project modification. The Town of Sunset Beach requests a permit modification to realign the proposed Bay Area channel, install a temporary bulkhead at the Cobia Street terminus, and construct a temporary offloading ramp at Seaside Road to support material offloading efforts. The Bay Area realignment will assist in reducing future dredging impacts anticipated by property owners requesting personal access to the navigation channel. These modifications will provide a viable plan for completing the dredging efforts with minimal environmental impacts. The project provides a key element for the Town and residents to manage the established navigation corridors on the east end of Sunset Beach. The project will help restore navigation access to the waterway systems on the east end of Sunset Beach while maintaining a buffer zone between the work area and any coastal marsh or wetland habitat. The project will also relocate shellfish located near the temporary bulkhead installation to reduce the potential for impacts. All materials installed as part of the temporary bulkhead will be removed at the completion of work. The work will also follow additional guidelines and recommendations provided by USFWS and NMFS to further minimize the potential for environmental impacts during construction. The project will adhere to environmental moratoria design to protect juvenile fish and shellfish. Additionally, the project will follow construction guidelines designed to protect manatee, sea turtle, and smalltooth sawfish. ADDITIONAL ITEMS RELATED TO CAMA PERMIT APPLICATION PACKAGE State Environmental Policy Act (SEPA) Compliance § 113A-12(6) states that the preparation of an environmental document shall not be required for projects that require a Coastal Area Management Act major permit. Therefore, no SEPA document will be prepared for the proposed project modification. Application Fee A permit application processing fee of $475 will be provided separately.

The application was received as complete on October 11, 2021 and appears to be adequate for processing at this time. The projected deadline for making a decision is December 25, 2021. An additional 75-day review period is provided by law when such time is necessary to complete the review. If you have not been notified of a final action by the initial deadline stated above, you should consider the review period extended. Under those circumstances, this letter will serve as your notice of an extended review. However, an additional letter will be provided on or about the 75th day. If this agency does not render a permit decision within 70 days from October 11, 2021, you may request a meeting with the Director of the Division of Coastal Management and permit staff to discuss the status of your project. Such a meeting will be held within five working days from the receipt of your written request and shall include the property owner, developer, and project designer/consultant. NCGS 113A-119(b) requires that Notice of an application be posted at the location of the proposed development. Enclosed you will find a "Notice of Permit Filing" postcard which must be posted at the property of your proposed development. You should post this notice at a conspicuous point along your property where it can be observed from a public road. Some examples would be: Nailing the notice card to a telephone pole or tree along the road right-of-way fronting your property, or at a point along the road right-of-way where a private road would lead one into your property. Failure to post this notice could result in an incomplete application. An onsite inspection will be made, and if additional information is required, you will be contacted by the appropriate State or Federal agency. Please contact me if you have any questions and notify me in writing if you wish to receive a copy of my field report and/or comments from reviewing agencies.

Sunset Beach. If that lot is used, it will substantially reduce the value of our property. Access to that lot is only via the small gravel road(Pecan Ave) adjacent to our property; that road is not sufficient to handle large trucks to haul away the spoils. The looks and smell of the spoils just a few yards away from our unit will be terrible. Due to our advancing age and difficulty traveling from Ca. we can no longer use the unit as our vacation home and six months ago we contacted a real estate agent to sell it. It is on the market. We respectfully request that the proposed Pecan Ave site next to our duplex unit not be used for the dredging spoils. James and Danna Collins; owners of 7323B duplex unit Sunset Beach NC RECEIVED SEP 14 2011 DCM WILMINGTON, P'C RECEIVED Dear Tara MacPherson, SEP 17 2021 DCM WILMINGTON, NC I have been a long-time follower and supported of the project to dredge the Canals, Bay, and Jinks Creek of Sunset Beach. As a homeowner and full-time resident, this is a long time coming and very much welcomed. I understand the changes that have been requested by Moffatt & Nichol. I fully support and agree with these changes. The addition of the landing off of Seaside Drive will greatly reduce the truck traffic on the island and shorten the distance to the offload site. This is a good thing for everyone and the environment. In regards to the project in general, it is important to note that those living on the water and that have the most personal impact are supportive of this project. We all have docks and moved to Sunset for the water and being able to enjoy it. I paddle these waters daily from my backyard on Canal Drive. The part of Jinks that crosses the Bay is no longer a creek. It is filled with decades of neglect. Those of us around the water call it Jinks Beach. The two or three that have been in opposition have provided no support and only offer opinions not backed by the studies and the modeling. It is unfortunate as it has cost this town a lot of extra time. My neighbors on the island can't wait for this project to begin. Pictures below were taken this past year at two different times. It is Jinks Creek off the end of N. Shore Drive. As you can see, there is no Creek except at High Tide.

Following approval from the North Carolina Division of Marine Fisheries (NCDMF), the relocation plan outlined herein will be implemented prior to the onset of any dredging actives. It should also be noted that this plan is similar to a shellfish relocation plan that was developed, approved by NCDMF and implemented for the Old Ferry Channel dredging project in Carteret County earlier this year. It is anticipated that the shellfish relocation efforts outlined in this document will take place in October of 2021.

Shellfish Relocation Plan • Relocation is proposed within all the dredge footprints of the areas indicated in Figure 2. • Relocation not proposed for any areas that fall below dredge depths authorized in CAMA Permit 132-18 and CAMA Permit 79-19. • Channel alignments will be programmed into a GPS. The GPS unit will be utilized in the field to locate areas proposed for dredging. NOTE: It should be noted that the Town is currently pursuing a modification to the authorized dredge alignment within the Bay Area. Shellfish relocation efforts will take place within the new dredge areas as opposed to the originally authorized alignment. • Relocation efforts will be staged from adjacent shorelines. • A skiff or two -person vessel, such as a kayak or canoe, will be used for collection. More than one vessel may be utilized in an effort to expedite completion of the plan. • Shellfish will be found by raking the bottom, either from a vessel or standing in the water. All shellfish found will be initially stored in oyster bags. • Once an oyster bag is full, the shellfish will be relocated to an area that is: o Outside of the dredge area, but in the same general area, and o Has an existing presence of shellfish, • Approximate GPS location(s) for each relocation area will be recorded. • Representative photos will be taken during various steps in the relocation process. • A Marine Patrol officer will be contacted 3-5 days before initiation of relocation efforts. Daily notifications of progress made, and anticipated work schedules/completion dates will also be provided to Marine Patrol (alternative notification procedures/schedules will be followed at request of Marine Patrol). • Notification of project completion will be provided to the North Carolina Division of Coastal Management (NCDCM) and NCDMF upon project completion. • A summary report for this relocation effort will be prepared and submitted to NCDMF and NCDCM within 30 days of completion of shellfish relocation efforts. The summary report will detail final relocation methodologies, locations of relocation areas, and provide an estimate of the number of shellfish relocated.
