JACKSONVILLE BEACH, Fla.- A project is underway to pump nearly 650,000 cubic yards of sand on to a seven-mile stretch of Jacksonville Beach, Atlantic Beach, and Neptune Beach.

The $13.5 million beach renourishment project is being undertaken by the Army Corps of Engineers and is meant to expand the beach and protect it from erosion.

Workers on the project are keeping a close eye on the path of Hurricane Matthew.

If the storm gets close, the corps says they will have to move the ship that's dredging sand offshore to safe harbor and crews will have to secure equipment including pipes, supplies, and vehicles.

One concern...how much of the work that's already been done will be washed away by Matthew?

"If that storm comes, its going to take it all back out anyway. All thtat sand they pump up will be gone if that hurricane hits us." said Beach resident Noah Sparkman.

However, the corps says that's not necessarily the case. Engineers tell First Coast News some of the sand that's een added along the sand dunes will stay in place. Renourishment projects that have been done every 5-6 years will help.

So while the project may get delayed, beach renourishment will eventually continue, no matter what the hurricane does.
