That’s the only time this property flooded in 100+ years
It’s a beautiful peace of land that would cost 3x as much 2 years ago.
If I can raise it 24” then half of Lafayette would flood before this house did.

Because the flood of 2016 flooded areas that had never been flooded before after 30"+ of rain in three days. Lots of shite will flood during that type of event. Doesn't mean it's going to flood every few years now. Personally, I would build a house where it floods once every 30-40 years. frick it. Get the flood insurance and just when you begin looking around your house thinking, "man, this is really outdated" BOOM --- FEMA renovates your house and you only pay a deductible.

dirt is about $13 a yard, do the math, you need 2500 cubic feet to raise a foot. thats 93 yards, not considering compaction. 1200 in dirt, whatever it cost to hire a dozer for the day...1k? compaction test is a few hundred.

Yeah, try to fill a 2500 cubic foot void with 93 cy and let me know how that works.

ETA: your ‘without compaction’ is still going to leave you short

Someone else mentioned it- so I just wanted to clarify I wasn’t including that in costs.

point is, its not much money in the scope of building a house. It all depends on the material used, soil engineer could tell you the shrinkage.

Couldn’t you just put your mobile home on two cinder blocks rather than one?

you will need to strip the first 9-12” off and the bring in select fill. Would end up with 3’ or fill and I recommend going out 10’ in all directions and then slope at a 5:1 or 6:1 slope. You are most likely looking at 70-80 loads. Here in Texas it’s about $125 per load to bring in and compact in lifts.

If you think you should go up 2’ go up 3’. You won’t regret it.

Built a house with a 3800s/f pad. Had to grub down about 12” and then had to raise 18” above grade.

24k

That also included clearing a heavily wooded 3/4 acre lot.

Ballpark $245/load in place if you can find a good dirt guy. 20 yds/load and compacted in 6-8" lifts.

Whatever it is, money well spent. I'm going to guess 3K.

50 dump truck loads ran me about $11k in 2001 to get base slab elevation 1” above the 100 year flood. Slab was about 4100 sq ft.

So about $220 per dump truck load.

I built my own Indian mound on the Amite

Sold before the flood which got a few feet over that.

My rented grass hut is over 240 feet above sea level, so excuse me for not living in that area and being intimately familiar with this sort of thing.

How far above sea level is the Baton Rouge area? I know that NOLA is very low -- that's where I am from.

But I don't know about Baton Rouge.

Short answer--for a 2500 sq. ft. house pad to go up 12"-15"----around $10-$12k.

That seems like the smart thing to do. It's got to be worth the "peace of mind" to have your new home on a 15 inch pad.

But you may be limited to a certain house elevation by the parish zoning. You can't flood your neighbors lot by having yours too high (runoff water).

If so, you will need to build a concrete chain wall around the property--that can get expensive quickly.
