I'll be surprised if the NPS let sand be put on CHNS beaches during turtle nesting season. Alright you can shoot the messenger now.??
Ready, FIRE, Aim!
Thought about that as well. My opinion - since the affected area is not conducive to nesting, and has little/no history of nesting, it would seem that renourishment would actually create habitat, and based on Dave Hallac's remarks, it seems the NPS agrees (hence the EA vice EIS). Win for the highway (public safety), win for the property owners and visitors, and win for the habitat.
To the OP (loblolly), I would not let this project affect your choice of destination. It is quite the engineering marvel, interesting to watch and in the unlikely event they are working the section of beach you want to visit simply head a short distance away and observe. If you have a capable 4wd vehicle, you will be able to enjoy as much NPS beach as is open near Buxton (which hasn't been much in summer) or slide down to Frisco/Hatteras Village.
