The South Shore Marina, which operates next to Fort Macomb. Running a marina in a frequently-flooded area must not be any easier than running a starfort there. I think the perfect business to operate in such an environment would not involve any sort of infrastructure, as most infrastructure doesn't do well when routinely submerged and repeatedly struck by wildly careening objects. On an unrelated note, my car, which had driven a literal thousand miles to get here, sure does look nice.
