First off, please stop spreading fake news. Newsom has already addressed all of your misinformation/disinformation here: https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fgavinnewsom.com%2Fcalifo...
A lot of the property up in the hills is large private lots, so who is going to clear the brush? California already has the leading forestry maintenance in the U.S. in terms of spend and expertise, and that includes clearing brush. The right-wing media apparatus just heard of this term, "brush clearing", and decided California doesn't do it, and that that incompetence exacerbated the fires. In reality, winds were carrying cinders hundreds of meters in all directions due to hurricane-force winds, and it didn't matter what brush you cleared because the cinders were going to reach the next flammable thing, no matter what.
California had plenty of water and full reservoirs. Having the water is different than *delivering* the water. There is no human-made system on earth that can instantaneously move a reservoirs' amount of water from one place to another, just like there's no road system on earth that can move a full stadium's worth of cars across the city at the same time. You don't build a municipal water grid to handle 100x the volume of water that a community could ever use, because the cost to build and maintain it would be prohibitive. Similarly, when dozens of crews were fighting fires all across the LA hills, the rate of water exceeded what the water grid could deliver, because it was a circumstance never before encountered.
