MEMORANDUM:
TO: Doug Huggett, DCM Major Permits Coordinator
THROUGH: Anne Deaton, DMF Habitat Section Chief
FROM: Jessi Baker, DMF Marine Biologist
SUBJECT: Stanwick Shores dredging, Paul and Susan Magnabosco, Topsail Beach, NC
DATE: November 26, 2012
The North Carolina Division of Marine Fisheries (DMF) submits the following comments
pursuant to General Statute 113 -131. DMF has reviewed the CAMA Major permit application
from Paul and Susan Magnabosco regarding the proposed dock reconfiguration and new
dredging in Topsail Sound. Depths inside this dredge footprint range from 0.6 to 2.5 feet at
MLW and SAV exists immediately adjacent to the proposed footprint. The entire footprint is
considered SAV habitat.
A similar dredging project was proposed in 2004 and denial was recommended by DMF due to
SAV impacts. On June 12, 2012, DMF met with the applicant onsite and confirmed the SAV
survey provided.
Dredging immediately adjacent to SAV beds directly exposes the area to erosion, slumping, and
deposition of sediments or overspill from dredge activities. SAV located so closely to a slip will
likely experience "prop dredging ". All of these scenarios will result in a loss of SAV. During the
onsite visit, staff learned that each slip will need to be approximately four feet narrower than
the existing slip width due to the conversion to boat lifts. DMF also notes that there are no
designated slips at the end of the dock. To avoid dredging impacts to SAV, DMF recommends
reconfiguring the docking facility so that all slips are moved closer to the channel and out of
SAV habitat. At this location, this translates to relocating all slips so that the landward slip
boundary is approximately 12 feet waterward from the existing location. Dredging will be
considered once impacts have been minimized through reconfiguration.
Due to the significant adverse impacts to SAV and SAV habitat that are caused by dredging
activities, DMF objects to this project. DMF would remove this objection if the proposed
dredging was reduced and moved waterward by at least 12 feet. Please feel free to contact
Jessi Baker at (252) 808 -8064 or iessi.baker @ncdenr.gov if you have any further questions or
concerns. One
