Picture is the results of a 1,000 year flood, not 100 year

Millions of homeowners face flood risks without realizing it, and climate change is making it worse

At least 6 million households are unaware that they’re living in homes that have a 1 percent chance of flooding in each year — putting them within a “100-year” flood zone, according to a new report. By 2050, 16.2 million properties will be at “substantial risk” of flooding in a given year.
Harvey was a 1,000-year flood event.  It had the highest rainfall accumulation ever recorded in the US.  BTW, the link is to a Washington Post story about the flood that was published in the Denver Post.

Homebuilders in the Houston, Harris Country area are required to make sure the houses constructed are above the 100-year flood plain.  I am skeptical that climate change had anything to do with making things worse.  It would be totally impractical to require homes be built above the 1,000-year flood plain.
