Local Climate & Risk Factors
Las Vegas receives under 4.5 inches of rain annually, but caliche hardpan soil is completely impermeable — even minor monsoon rainfall (July—September) triggers catastrophic sheet-flow flooding. The Las Vegas Valley Wash and Flamingo Wash overflow during any significant storm event. Extreme heat (120°F+) causes AC condensate systems to work overtime, creating chronic overflow failures. Hard water (800+ mg/L TDS) accelerates pipe scale buildup and pinhole leaks in copper plumbing throughout older properties.
Flood-prone areas: Summerlin and Henderson are premium markets with newer construction; Downtown and North Las Vegas have aging 1960s—1980s plumbing most prone to pipe failures; Spring Valley and Paradise have highest AC-related water damage rates due to dense multi-family construction
