Guys the lessons of Sandy, Katrina and now Harvey are what really matters as well as whether or not those lessons will be heeded but in the meantime two obvious measures need taken . First, get those damn people back away from the coast. The cost of rebuilding entire cities every few years is busting the federal treasury. Second and hopefully Southern cities such as Houston will finally realize the benefits of zoning including not allowing upscale housing developments to be built directly below reservoir spillways.
