oo much development in southern areas of Calcasieu the past 20 years in rice fields has (1) removed those fields as drainage areas and (2) put housing in historic area of drainage/water accumulation during rain


yet the mayor and the weatherment are spouting a bunch of climate change bs instead of admitting the problem

same thing in south of Lafayette and south of Baton Rouge - all development South of town in old sugarcane fields

You do understand it’s more than one problem, right? Also, let me know when you find a city that doesn’t flood if 15” of water falls on you in less than a 10 hour time frame.

Yep. And we will be told that there is no planning for 1,000 or 500 year rains. Or they will say "Engineers designed it".

It is all about the money. Follow the incentives always. Engineers get paid. Developers get paid. Parishes get paid. Cities get paid. There is no one to check them.

Homeowners who want to contest it are not going to get lawyers or engineers to check every project independently. It would cost a fortune.

we're getting rain the next 3 days. we can handle more rain (in terms of flooding) in most places b/c there is drainage that works. it just can't handle a ton dumped in an hour or whatever. however, some areas are f'd. too much development in southern areas of Calcasieu the past 20 years in rice fields has (1) removed those fields as drainage areas and (2) put housing in historic area of drainage/water accumulation during rain


Morgan field will eventually cause drainage problems in that area.

yes, but if that happened often and not expected to change in future would you expect things to change in how development was done?

You can certainly plan for them, but affordability of houses in neighborhoods designed to a 0.2% annual chance flood elevation is the issue. You are correct though that people don't understand risk because they never get a proper explanation from the housing industry on what it means.

Replying to latest post.

My buddy has a fancy rain gauge and sent me this text. We live at the corner of Hoo Shoo Too and Jefferson.

“ My rain gage recorded 13.1” yesterday. 10.9” of it between 7pm and midnight.”

It won't fix all the drainage issues but they put some massive retention ponds in when they built those neighborhoods. Still are digging them as they add on too.

My mawmaw has lived in her house for over 60 years and this is the highest water she has ever seen at her house in giesmar. Its raining alot no doubt but the problem is all this fricked up development. Prime example: Spanish lake primary school was built in a slough and is basically a huge arse damn blocking everything south of it from getting to bluff swamp.

So give me the climate data that supports the climate change stuff because out of the top 10 rainfall events for LC many were 40-50+ years ago

Also they should have pictures of the same kind of flooding in LC from the events in the 1940s and 50s

who's getting 10 more in of rain on avg every year?

2018 we were at the avg, 2019 we were above, 2020 we were actually under and if not for the hurricanes we would have been in a drought in the fall

2021 was way under the avg until a couple weeks ago
don't be suprised if the ridge thats moving in Friday stays a while and we have a dry June

I think you missed my point. It seems we are having 500 year rains far more often now in South LA.

The original master plan for Morganfield was designed for 100 yr capacity. I know because I did that plan. That was almost a decade ago I did it and I know they have changed it some since then, but the developers were more aware of runoff than most.

This is true and is an issue in the majority of the country.

the really southern areas didnt really even flood except in some low lying areas. Thats not what happened.

1) the city still has a ton of drainage issues from the hurricane

2) you had a 100 year storm of 15" in less than 12 hours. Drainage is designed to handle basically an average 100 year event. This was mroe than that

3) most of the worst flood was on lake street due to contraband backing up. why is it backed up? because water levels were already high before the storm.

the areas that flooded didnt use those fields as drainage. And as far as historic flooding events....sure those flooded as expected but the ones along lake have never really flooded.

its not like LC is flooding all the time, but drainage is a big issue in the city. Alot of it is BS by the city. For example, my terra saint neighborhood is missing close to 20% of the drains that are on the approved plan by the city council. no changes were approved by the council, yet the subdivision owner was allowed to get away with this bullshite because the city didnt check and is not good at checking and forcing their had even when they do get out there.

My biggest problem is the people who were here first are the ones getting fricked the hardest. The old people built their houses in the prime spots because they weren't stupid. Now the parish will issue permits to anyone to build a big arse subdivision across whatever low spot they want as long as they dig a big hole in the middle of it. Boy let somebody who's been here try to do something though, the parish will give them more bullshite than ever seen.
