Flooding
Although the average annual rainfall is only about 8 inches, many parts of El Paso are subject to occasional flooding during intense summer monsoons. In late July and early August 2006, over 15 inches of rain fell in a week, overflowing all the flood-control reservoirs and causing major flooding city-wide. The city staff has estimated damage to public infrastructure as $21 million, and to private property (residential & commercial) as $77 million . Much of the damage was associated with development in recent decades in arroyos protected by flood-control dams and reservoirs, and the absence of any storm drain ultility in the city to handle the flow of rain water.
