SUBJECT: Management summary: Magnetometer survey of New Topsail Inlet in
conjunction with proposed dredging and beach renourishment for Town of
Topsail Beach CAMA Permit Major Modification 22 -09. ER 11 -2331
We have received the management summary reporting the results of a magnetometer survey
conducted by T.I. Coastal, PLLC in the New Topsail Inlet channel, a federally maintained
waterway with an authorized width of 150 feet and a depth of 8 +2 feet. The survey revealed
no strong magnetic anomalies within the New Topsail Inlet section of the proposed
dredging project. The survey did discover several strong magnetic anomalies within the
Banks Channel section of the proposed dredging project. These anomalies do not appear to
be related to shipwrecks and are within the location of a formerly maintained channel
marker buoy indicating the channel between Topsail Creek and Banks Channel. It is likely
that the anomalies were caused by formerly used buoy anchors and associated chain. These
are not significant in terms of cultural resources.
Because no evidence was discovered suggesting significant cultural resources within the
dredging project footprint, we have no objection to the project as proposed. In the event
that submerged shipwreck materials are encountered the NC Underwater Archaeology
Branch should be immediately contacted (910 458 9042). A staff member will be sent to
assess the material and determine the proper course of action.
If you have questions concerning the above comment, please contact Renee Gledhill- Earley,
environmental review coordinator, at 919- 807 -6579. In all future communication concerning
this project, please cite the above - referenced tracking number.
