If your ground surface elevation is 20.0 and the BFE is 22.0 then your ground is 2 feet below the BFE. If your lowest finished floor of a structure enclosed on three sides is 22.5 then your finished floor is 0.5 feet above the BFE. YOUR FLOOD INSURANCE IS RATED BASED ON IF YOUR FINISHED FLOOR IS ABOVE OR BELOW THE BFE. The flood maps are called FIRM maps. Flood Insurance Rate maps. They are actuarial devises used to establish flood insurance rates for your location. It is used to assess risk. IT DOES NOT MEAN THAT YOU WILL OR WILL NOT FLOOD. There could be a culvert plugged or a bridge obstructed that could cause you to flood in a five year event and every body else downstream of that would be fine.
A bit of further clarification. The FIRM maps are what FEMA uses to establish rates so that they can generate premiums to cover future claims. They really really really want you to purchase flood insurance so they can generate premiums to add to their reserves. In their eyes, if you want to play you got to pay..
I was referring to post 209 where he was using 20-25 feet above BFE. I understand the FIRM maps. We use them daily in our industry although I'm not an expert in their calculations such as you as I assume you are an engineer or surveyor or both. The point I was trying to make was that being 25 feet above the BFE here is highly unlikely or at least I haven't seen this since our topography doesn't change so drastically. When Amos referred to being 20-25 feet I suspected that was his ground elevation, not the distance from BFE.Quote:

That last sentence is probably as important as any other factor in making an evaluation and decision as to whether or not to carry flood insurance. If your property is generally at a low risk to flood, the insurance premiums will be cheap and you will have coverage if something like that happens.
Where I live it is high and there is a real remote chance of flooding. I have always carried flood insurance. However, about 20 years ago when we had open ditch drainage, there was a very heavy rain in a short period of time and We almost flooded. As the water began to rise, I rode downstream from where my lot drained and found a garbage can top stopping one of the driveway culverts. That little obstruction with unusually heavy rain in a short time period almost did us in.
Get your flood insurance.
If you live in Lafayette, look the the ditch next to Prarie Elementary. Nice big concrete structure, full of debris and silt. If your old enough, you will remember the coulee runs under Albertsons and St. Edmond's to drain Orgeron Heights. How much sediment is stuck up under there? That all drains to the river near Dien's Salvage yard (old Lipstick's Club).
The reason I got from LCG for lack of maintenance was the concrete sections in the city are over a foot lower than some of the non concrete parts of network west.
on the flip side, actually a good fishing hole. I've seen guys pull bass and catfish out along there.
I don’t think I mentioned this but have to credit my wife for her efforts in the last Abbeville flood——went about half a mile in a pirogue to get to the highway for a ride to the office.....and like a Good Neighbor..........!
You never mentioned the pirogue Boomer.Quote:

Since Rita, if the south wind blows at a decent clip for a couple of days, the ditches fill up with water NORTH of Hwy 14 in Erath.Quote:

If I remember correctly, with Rita 90E was closed at Golden Meadow and the port of Iberia due to storm surge.Quote:

Same with me in 2016. I never even had water in my yard the previous 23 years. About 14 inches in my outside kitchen, garage and bar. It would have had to go up another 24 inches to get into the house. 30 inches of rain in that 24-48 hour span was a lot of water. The river couldn't take that much. And my carpenter thought I was crazy building my house up that high on pillars 26 years ago.Quote:

this is the Vermilion River at 733
this is the Vermilion River at Surrey. you can see that the influence is not as pronounced and is delayed but it is there.
Went to New Orleans today and I took I10 on the return home. When traveling westbound on 10 across the Pontchartrain, I noticed there was a rush of water coming from the South/left. Assuming that was coming from the MS River??
