The desert’s relationship with water is deceptively dangerous, and for residents living in certain parts of the valley, monsoon season is anything but a background concern. Understanding which areas are genuinely at risk, and why, is one of the more practical things a Las Vegas homeowner, renter, or buyer can do.
