re: Can someone explain to me why La hasn't poked holes in the walls along I-12 in DS?

Livingston Parish folks want that wall gone so they can flood everyone else instead.

am south of I-12 in Denham Springs and had four feet of water in my house. People farther south in my subdivision had water up to their roofs. There were more factors than the interstate wall.

The factors were a 1000 year storm. And man developing flood basins. Clearing 1000 acres and throwing in a few retention ponds and thinking it’s all equaled out works for a couple inches of rain. Not three feet of water falling from the sky.

God hates Livingston Parish.

And even if the state loses the suit there is no mechanism to make the state correct the issue or pay damages.

They're idiots. They were already sued for the exact same thing. lol

Again, this is dumb. The purpose of the wall wasnt supposed to be to create a dam that saves South Baton Rouge and increases flooding and danger to northern parts of Denham and Central.

Can Denham and Central create a dam north of it now? Its all good, right?

how many houses didn't flood because of the wall?

---

Probably none. Houses just on the south side of 12 at Juban took on plenty of water.

I12 is a dam across Muddy creek right there. It is a low spot. Just like the area by the Amite. The water collects in low areas. There is a pic somewhere of both sides of 12 flooded at the hospital. Just the I12 dam sticking up.

OP worried about the stubby wall on top on the dam.

Ask some in Walker and they would tell you the water would have been 3' lower at their house had the wall not been there.

do you know the difference between 1' of water in your house and 3'......nothing.

Exactly. They were fooled by the cropped picture showing water only on one side of the wall at a high point.

If you pan the shot out you can see that water was flowing around the wall at the low points.

and what about houses further south that didn't flood....seems they could have flooded if that water wasn't held back, right....seems logical

---

Flood plain gets wider the further south it goes. Takes lots more water to rise a little (also takes longer to come down).

Maybe you could find a house that benefited, but it was a minor amount of water actually being held back by that wall when looking at the scale of the flooding.

Logically, sure maybe someone was spared. There is that chance.

The most puzzling thing to me is after the flood when I12 continued expansion, they did not begin installing drain ports on the wall.

---

Yes they did. And it did not make their attorneys happy.

This is why those towns flooded, not because there weren't some weep holes in a wall. Plus, like someone else already said, not one government agency on this planet would design that wall with a 1000 storm in mind. It's impossible.

Duh, flooding was inevitable

But

The Eastern flow towards Walker was exasperated by the Interstate wall.
