Ok. Here’s a crazy idea. We just…stop with the street cleaning and trash collection. First, pass a law that everything must be sold in biodegradable containers. Then, just let things lay wherever they are dropped! Over time, like archaeological sediment, all the trash dumped in the French Quarter will slowly compact, decompose, and turn into soil, thus raising the elevation of the ground. As the French Quarter is already one of the highest elevations in the city, this increased sediment will flow downhill, gradually raising the elevation of the entire city. Eventually, they won’t even need the dyke system anymore, as the whole city will be raised well above sea level! The city will be like one of those ancient Mississippian mound building cultures. Except this mound will mostly be composed of piss, vomit, and plastic beads.
