They could, but how? It's 300 feet deep. they'd have to spend a ton of cash to shore up the sides and make it safe. Even then.... Another hurricane could still cause more to wash out.
Just put up walls around it and say, "Hey wanna see it? Twenty bucks." And if expands, just build a new wall and raise the price. Maybe you can even sell people five dollar rocks to let tourist throw them down to try to hear it hit the bottom. Then you're making money on the crater being filled. Might take a few hundred years, but that's a government job for ya.
