The Town of Ross is prone to flooding. Areas near Corte Madera and Ross Creeks are most likely to flood during storms. Ross has experienced three 100-year storms in the past decades (1982, 1986 and 2006). Engineers use the term "100-year storm" to describe a storm that has a 1% chance of occurring in any given year (not a storm that occurs only once in 100 years). Even less severe storms cause Corte Madera and Ross Creeks to rise and local flooding problems. The Hazard Mitigation Plan has additional information on Town flooding.
