RAWLS Director May 5, 2022 Gregg Bodnar, NCDMC Assistant Major Permits Coordinator NCDEQ Division of Coastal Management 400 Commerce Ave. Morehead City, NC 28557 Re: Szwankowski boat ramp, Baird's Creek, Pamlico County After discussions with staff, I concur with their recommendation to deny this application to install a boat ramp, groins, and access pier on Baird Creek for personal use on their property. The ramp would require dredging an area 50' by 12', installing sheet pile groins parallel to the ramp, and a 50' access pier adjacent to the ramp. The applicant already has a separate docking facility. Site visits in March and April found that the entire shoreline was heavily vegetated with submerged aquatic vegetation (SAV). Patchy and dense SAV occurred in the proposed ramp area, as well as along the adjacent shoreline. SAV is a critical habitat for nursery, refuge, and foraging for a variety of recreationally, commercially, and economically important fish and shellfish species. Additionally, SAV improves water quality and reduces shoreline erosion. Removal and loss of SAV in this location would have significant adverse impacts on fish and fish habitat. Thank you for the opportunity to comment on this application. Please keep Jimmy Harrison informed on the final status of the proposed project.

RAWLS Director TO: FROM: James Harrison, NCDMF Fisheries Resource Specialist SUBJECT: Szwankowski Application, 411 Baird Point Road, Pamlico County DATE: 9 May 2022 Gregg Bodnar, NCDCM Assistant Major Permits Coordinator A North Carolina Division of Marine Fisheries (DMF) Fisheries Resource Specialist has reviewed the permit application for proposed actions that may impact fish and/or fish habitats. The applicant is proposing to install a 12' by 50' boat ramp and install a new 4' by 50' access pier along one side of the ramp. The applicant is also proposing to install two 50' sheet pile groins along each side of the ramp, with the landward 25' having 1' of exposure and the remaining 25' cut flush to the top of the ramp. Water depths range from 21" at 10' from the normal water line (NWL) to 50" at 50' from the NWL. The ramp will be for private use by the owner of the property. No submerged aquatic vegetation (SAV) was observed during a site visit in February of 2022, but the field report indicated that "some" SAV was observed 10-20' waterward of the NWL during a site visit on March 8, 2022. Because SAV was observed during the March site visit, DMF initially requested that an SAV survey be completed to adequately and accurately assess the potential impacts associated with this project. Rather than impose additional costs on the applicant, DMF staff conducted site visits on April 21 and 28, 2022 to observe and document the SAV on site. SAV presence was documented by making visual observations and by raking samples along transects throughout the project site. Rake samples were used to determine species composition. In waters too deep to safely sample, visual observations were made to the best of staff ability. Measurements were made in feet to remain consistent with the spacing of the pilings of the community pier. Sampling was completed using the neighboring community dock for shore -perpendicular reference points. References below to piling numbers are based on piling number 10 being the last piling before the first finger pier of the community dock (see Figure 1). A transect tape was placed across the length of the project area for spacing of shore -perpendicular transects. DMF staff conducted transect lines at approximately 10' spacing along the transect tape. Rake sampling was done at the intersection of the transect line and the community dock pilings. Visual observations were made in a 100 square foot (10' by 10') area around each rake sample. State of North Carolina I Division of Marine Fisheries 3441 Arendell Street I P.O.

A dense bed of SAV was observed, starting approximately halfway between pilings 3 and 4. There was some patchy SAV shoreward of this line, especially on the northwestern side of the project area. In that area, the patchy SAV extended to and was mixed with the marsh species. Overall, the dense SAV bed started between pilings 3 and 4 (Figures 2, 3, and 4) and extended past the terminus of the community dock — including within the slips — and extended along the shoreline in both directions. SAV coverage throughout this bed was greater than or equal to 75%, based on the rake samples and visual observations (Figure 5). The SAV observed throughout the site was a mix of widgeon grass (Ruppia maritima) and horned pondweed (Zannichellia palustris).

The samplings taken parallel to piling 4 showed a mix of approximately 75% widgeon grass and 25% horned pondweed. Parallel to piling 5, the ratio had shifted to a more 50-50 mix, and this continued through piling 6. From piling 7 onward, the mix was approximately 25% widgeon grass and 75% horned pondweed (Figure 6). The area also included a variety of other three - State of North Carolina I Division of Marine Fisheries 3441 Arendell Street I P.O.

SAV is a critical habitat that provides numerous benefits to a variety of recreationally, commercially, and economically important fish and shellfish species. Some of these benefits include foraging, refuge, and improved water quality. SAV has also been found to provide natural shoreline stabilization and nutrient uptake. For these reasons, the protection and restoration of SAV habitat is a key priority issue included in the North Carolina Coastal Habitat Protection Plan (CHPP). The proposed project would also require removal of the habitat -forming structures (i.e., woody debris) that was observed during the site visits. These structures provide additional habitat to fish that utilize the area, including refuge and foraging (via attachment to structure by small prey State of North Carolina I Division of Marine Fisheries 3441 Arendell Street I P.O. Box 769 I Morehead City, North Carolina 28557 252-726-7021 species). Fish were observed preying on these small species during the site visits, providing evidence of the benefits of these structures. DMF has significant concerns with the proposed work and the potential impacts to SAV habitat and the fish that utilize the area. First, the project would result in the direct removal of SAV habitat, as well as the habitat -forming structures mentioned above, during excavation for the ramp. The installation of the proposed structures would also result in increased turbidity and sedimentation, impacting the SAV in the surrounding area. The proposed groins along the sides of the ramp have the potential to alter wave and energy patterns, impacting the water flow to SAV habitat and potentially causing increased sedimentation in surrounding SAV. Furthermore, the use of the ramp could lead to continued impacts to SAV waterward and surrounding the ramp, such as damage to SAV caused by vessels and/or vehicles, as well as issues associated with vehicular contamination (i.e., fluid leaks). Based on the above discussion, DMF recommends denial of the permit application for the proposed work due to the potential significant adverse impacts to fish and fish habitat at the project site.
