Act of nature ? Sure, hurricanes are exactly that. But Hurricane Harvey’s massive troubles are as much man-made, as they are natural. A classic case of negligence gone wild, over generations.
Before Affirmative Action bumped me out of my graduate school of urban planning, I did manage to learn how lack of proper care of urban environments, can bring disaster on a catastrophic scale. The problem with Houston is too much real estate development, creating too little greenspace. Too much pavement (roads, parking lots, housing, etc), and not enough land left natural. When you pass a certain level of covered ground, you get flooding.
With soil, water can seep down into the earth. But with pavements, it lies on top, with nowhere to go, but build up higher (AKA flooding). Runoffs (streams , sewers, etc) quickly become saturated and useless.
In addition to the overdevelopment of land in the city, there is also the factor of underdevelopment of exit routes. Houston’s mayor (correctly) stated that mass evacuation was not feasible, due to the problem of traffic congestion, with dangers of accidents, and heat stroke deaths (that have occurred previously)
Again, lack of planning (or the ignoring of advice from city planners). Had more land been left unpaved (including roads), and more exit routes been constructed, Harvey would not be the catastrophe that it is.
In the old days, when roads and parking areas where dirt, generally, hurricanes’ effects were not as severe.
