A majority. One part of town gets shady and we quickly hop over to another part. Put in roads that act as water funneling measures and before long, we have an ate up flood plain. This would not have been nearly as devastating had the water not had to fill up entire sections at a time before proceeding on to the next area.

It is BS this is a 500 year event.

During the flood of 1927 the Tickfaw, Amite and Tangipahoa flooded such distances they met.

SGS has done a few studies on the subject. It seems common sense enough.. water traveling along impervious surfaces reach streams more quickly than it should. Large amounts of water in a short amount of time = flooding. Increasing the amount of water (or decreasing the time it takes to reach a stream) = increased chance for flooding.


Very insightful....seems like a lot of folks on here refuse to believe that this kind of thing has had an adverse effect on the degree of damage. The points you make seem very sensible.

Of this particular flood? Only a small portion can be attributed to irresponsible development in this case. The more water you can have infiltrate where it lands, the less you have flowing in to waterways. BR and surrounding areas have been terrible at enforcing drainage regulations and implementing modern stormwater best management. That said, there's frickall you can do with 20" of rain.

USACE land can buy up land to help relieve flooding at the cost of crops..seems like a fair deal to me. Lease to farmers and give them a great deal.. with the stipulation that if you get another 20" rain event then we are flooding the shite out of that area instead of homeowners and compensate them for the value of crops lost.

But yeah.. 20" of rain.. good luck

I'm just throwing things at the wall, but I wonder what rougher concrete/asphalt would do, or adding strategic ripples in the road would do

It has nothing to do with actual years. It's about the probability of it happening in a single year.

1/1000 or 1/500 probability that something like this would happen in any given year hence the phrase "1000 year flood"
