Davis, Aaron; Gillum, Jack; Tran, Andrew. „How Houston's 'Wild West' growth may have contributed to devastating flooding“. Washington Post (anglų). Suarchyvuotas originalas 2018-03-27. Nuoroda tikrinta 2018-09-10. „At the same time, severe storms are becoming more frequent, experts said. The city's building laws are designed to guard against what was once considered a worst-case scenario — a 100-year storm, or one that planners projected would have only a 1 percent chance of happening in any given year. Those storms have become quite common, however. Harvey, which dumped up to 50 inches of rain in some places as of Tuesday afternoon, is the third such storm to hit Houston in the past three years. In May 2015, seven people died after 12 inches of rain fell in 10 hours during what is known as the Memorial Day Flood. Eight people died in April 2016 during a storm that dropped 17 inches of rain.“
