You should be letting the fire dept decide what the new bldg codes should be.  Other states require fire suppression built into homes, along with fire resistant construction material, NO wood frame and metal roofs.  Before construction you should bury all of the power lines, which may have contributed to starting this.  Also no greenery within 30 feet of homes.  Plus put in additional reservoirs through condemnation if you need to.   CA's non-stop fires are destroying air quality for all of the SW States.  You are also using way too much water from the CO River.  You need to examine every problem identified in this fiasco before rushing to rebuild.
