Flooding can cause various hazards, especially for Los Angeles County. Los Angeles County has had issues with flooding and El Niño could possibly lead to severe flooding and mudflows. Los Angeles County coastal areas have been severely affected by El Niño three times during the years of 1977-1978, 1982-1983, and 1997-1998 (FEMA, 2011).

Living in the highlands can help protect residents from flooding, but puts them at the risk of landslides or mudflows (California Coastal Commission, 1995). Mudflows (also referred to as debris flows) are hazardous because they carry debris downslope that can severely damage homes and possibly endanger lives for those that live at the bottom of the slope (California Geological Survey,

The ability for water to infiltrate the ground is non-existent when there is concrete surrounding the water. Without the ability to penetrate the ground, the amount of runoff is increased dramatically. A large decrease in one area of the water cycle only leads to a large increase in another.
