BECAUSE of a black mayor? (As an aside, you know that the Mayor doesn't control the budget alone? I know you are a Trump thinker and see govt leaders as owners of their own business' that can do anything they want, but that's not how it works in govt)
Municipal water systems are not sized to fight wildfires of this magnitude. Especially in terrain with hills, mountains and valleys. Do you even understand the basic principles of how municipal water systems work? Gravity, head pressure, tanks, reservoirs etc?
These tanks, mains etc were sized and installed decades ago. They can only feed so much water through the water mains, and when there are so many hydrants open the pressure drops. And worse in the valleys due to gravity.
Besides, NOTHING could stop this magnitude of a firestorm in these sort of winds. It is like a self-sustaining and self-accelerating nuclear reaction. I've seen way less first hand and nothing stops it.
