What the hell is lining 16 miles of Jones Creek with concrete going to do to improve drainage?
Reduce vegetation blockages that they apparently can't be bothered to maintain.

The worst thing you can do to a drainage canal, creek, stream or bayou is to concrete line it. Concrete lining it destroys the ability of the drainage feature to naturally allow it to change in response to increased flow.
Instead of spending money on concrete ( which over time will fall apart and let trees grow up in it) use that money to buy the land adjacent to the drainage creek and widen the creeks so that they will have more carrying capacities of damn water.

Areas in St. George were devastated by the floods and still have flooding issues because they rubber stamp the cookie cutter developments. A handful of that $20 million is set to be spent in that area while the general fund kept raking in the sales tax over that same period. Another reason why it's good the area incorporated.
The local govt. subsidized one large development in SG in the area south of Highland. There’s way more going on in this flood plain than just cookie cutter developments.

Concrete is good fir two reasons, if you want water to escape faster it moves water quicker. It is also easier to maintain
Now if you want to retain water and you have money for more maintenance then yes, don’t line canals.
But you have to have a strategy. In EBR we have none and we do very little maintenance.

Concrete lining the canals will push floodwaters quicker down on those people living downstream. And over time those concrete panels buckle, break ,and fail, trees and vegetation grow in the areas where they fail. The parish does NO upkeep on these things once they are poured.
This is the worst thing you can do to a natural drainage canal such as Jones Creek !

FEMA isn't going to approve anything that doesn't come with a FONSI (Finding of No Significant Downstream Impact). Lining a canal with concrete isn't radically different than rocks with GeoTech Fabric (only the slope and capacity of the canal and drainage structure at that point become more static for a longer period of time which actually removes variable from drainage questions or issues over time as it remains more consistent).
Your concerns are overblown and not reflective of the permitting (which is onerous) issues and the abject lack of maintenance that's ongoing now. If you don't do channelization improvement they natural impediments due to a lack of clearing and grubbing will create far greater issues. Which it's-literally-obvious to see right now with current conditions.

The worst educated state in the nation and this surprises you? It is the blind leading the blind. They could solve the catch basin problem by just having prisoners go out there with shovels year round. I'm sure a study would have tk be commissioned first though

Yes, if the water is allowed to escape BR faster and before the flooding waters from the north get to DS then flooding can be mitigated somewhat. Concrete lined canals csn be a key part of a larger strategy. Getting water downstream faster can be good in the tight situations and it’s definitely easier to maintain

Right now those canals are clogged. They have to do something.

As opposed to overgrowing every year and getting clogged for every storm? Not to mention eroding away in some areas.
EBR and Livingston both approved these plans, and they are designed to add a net zero gain in flow downstream. They can build retention areas and widen the channel to slow the flow with steeper banks enabled by concrete bulkheads. That’s what they are doing - and they are acquiring land along side the canals to build wider estuaries to retain water in flash floods.

They don’t upkeep the overgrown mud-lined canals either. At least the concrete linings hold up for some time.

False. The worst thing they can do is nothing.
They have a serious problem getting water out of neighborhoods because of how overgrown and obstructed these “natural” waterways are. Trees, bushes, silt, garbage, and even yard waste are causing floods.

It is. They are widening channels with steeper banks and building overflow estuaries to retain water during flash floods.
It’s a bit more nuanced than that poster is comfortable with.
Frankly Livingston Parish needs to do something similar. And we need to get the lower Amite basin dredged regularly.

Unfortunately, all the impacted parties cannot afford to challenge and check every single one to make sure they are properly designed. No way local government and developers etc, who are all making tons of money off of this, could be making mistakes.

But dredging Ward's Creek and Bayou Fountain without doing something to Bayou Manchac only makes these two streams larger reservoirs for holding backwater. See Bayou Fountain today - level still very high ~30 days after the great rain.
Somehow addressing Bayou Manchac needs to be the priority. Otherwise, water from Bayou Fountain and Wards Creek has no place to go. Do the powers that be not understand this ?

I stand by opinion.
Lining these creeks with concrete is a mistake.
Those living near the Amite River will have a sudden rush of floodwaters dumped on them all at once if those creeks are lined with concrete,

If you check ordinances locally, most HOA’s are liable to maintain their own detention/retention facility’s capacity. If they aren’t then EBRP’s completely left the barn door open. Most parish and local ordinances in Acadiana require the HOA to maintain drainage/retention capacity while retaining emergency access ROW.
It’s easily done and is done throughout Louisiana. If EBR and surrounding municipalities in the 10/12 corridor area aren’t doing it, it’s a function of ignorance and laziness on the part of their elected leadership.

How about a pumping station or two???
