Arizona has Zone 1 radon risk across most of its area per EPA's 1993 map. FEMA NFHL coverage is dense in flood-prone Maricopa + Pima counties; wildfire risk concentrates in Yavapai + Coconino + Cochise. Water-rights and utility-source diversity (CAP allotments vs. local groundwater) varies significantly between metros.
