California context
Wildfire (WUI), seismic, water-supply variability
California carries the highest concentrated WUI wildfire risk in the US per USFS WHP, with FAIR Plan + non-renewal pressure intensifying since 2017 fires. FEMA NFHL coverage is strong; drinking-water systems vary from large urban (LADWP, EBMUD) to small disadvantaged community systems flagged in EPA SDWIS. Radon risk is mostly Zone 2-3.
Nevada context
Wildfire, water-supply (Colorado River allotment)
Nevada's wildfire risk concentrates in the western Sierra foothills (Reno, Carson City, Lake Tahoe). Las Vegas water supply tied to declining Lake Mead Colorado River allotment. EPA SDWIS shows arsenic challenges in some rural systems.
