bulldozer and sand pile

I was wondering why in the cam there is a bulldozer piling sand up ? Just curious as to what is going ?

must be the beach renourishment. My condo hasn't had any yet, so I am surprised to see that Schooners is on it's 2nd one.

ok thanks for answering my question.

that is for the lobsterfest. they will carve a sand sculpture out of it
