Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to ort.spam@nc.gov All, The subject channel was surveyed following Hurricane Dorian and through coordination with the USACE navigation branch, a slight modification to the orientation of the proposed maintenance channel has been made. Attached is an updated set of plans showing the channel as proposed in August and the updated channel alignment modified after Hurricane Dorian (See Sheet 3). At present the schedule has been pushed back a few weeks due to an issue with the MOA between the State and USACE. Both entities are working to remedy the situation and we will provide an updated schedule as soon as we nail it down. Please feel free to reach out to me with any questions.
