    Building on a swamp at sea level probably wasn't the best idea of all time.
  • Sold home in Katy in April and left TX. It's unbelievable the development in the wetlands... and it's not slowing down.
  • @777dingo
    because it got 50" of rain and it's not on a hill, any city would flood under those circumstances
  • There were a combination of things that contributed to Houston flooding.
  • Land Developer: "We don't need no stinkin' wetlands!"
  • @HIDhater
    What never gets mentioned in any discussion is the composition of local soils. They are known as Vertisols which are self mulching, highly expansive clays. Bone dry, they can absorb up to 1” of water then become impermeable like concrete as the clays expand. That’s why rice is a good crop here... they hold water.
  • Take a lesson from Japan. They have one hell of a flood control system in place.
  • I live in Houston and I am blessed that it didn't flood on my street
  • My neighbors dogs are still missing 😢 he was a sleep when it flooded he went to his backyard and his dogs were gone 😭 hope someone found them and is giving them love and care
  • I remember in 2012 Woodstock Virginia, United States. A flood hit us i was 7 years old, being a little girl I didn't understand nothing about a flood. All I remembered was seeing ambulances coming in my neighborhood, and 2 men carrying my family. 1 men was carrying my older brother and I, the other man was carrying my older sister and mother. My kitty unfortunately passed away or maybe ran away during the flood, we tried taking her but there was no time. But the mother cat survived.
  • I live here in Houston and we had a major storm some years back that was called Allison Allison had nothing on Harvey he came with a vengeance it's definitely something I would never forget it's going to be a year this month since that. Disaster hit Houston
  • Reasons why: •Massive Amounts Of Rain •Near The Coast, Which Means The City Is Low And Easy To Flood
  • I'd say the biggest problem is that all of our bayous converge into one. It's clear since that's the one that's still flooded over a week later as everything drains into it
  • I’d really like to know how full the reservoir’s were prior to Harvey. I took my first drive ever up Westheimer parkway 2 weeks prior to Harvey, and it was flooded pretty good from heavy rain a few days prior to that, for instance there were trees that were a foot deep in water. I also did some mountain biking at the anthills(which is right beside the buffalo bayou, which is we’re at least some of the barker reservoir drains into) at least twice in the two weeks before Harvey. The water level did not seem high or fast at either time, and I have seen it very high before and fast moving as I now rent an apartment right next to buffalo bayou. I suspect that they waited too long to release the reservoirs and then had to release them when it was way too late, I also wonder if they released any of the water from 2 weeks prior to Harvey.
