I have a client who is proposing a new garage on his small, gently sloping property near a river. About 1/3 of the proposed garage is up to about 6 inches below the BFE. I'm preparing a plan showing the proposed garage with proposed fill around it to submit to the local conservation commission, then apply to FEMA for a LOMR-F to avoid flood insurance.

Due to extremely limited area available to provide compensatory storage for the fill in the floodplain, I am proposing a timber landscaping retaining wall on 2 sides of the garage, about 2 feet away from the foundation. This wall will be backfilled to 6 inches above the BFE. The proposed wall height is only 12 to 15 inches high maximum.

My question is:
Does anyone know if FEMA will accept this (for the LOMR-F) as long as the LAG immediately adjacent to the foundation is higher than the BFE? I don't see why they shouldn't, but before I go to far with this, I thought I'd ask if anyone has tried or seen something like this before.

Absolutely they will. As long as the town will sign off on the loma f showing approval.

We did one where a guy put a wood tie flower bed on one corner of his house and filed a lomaf

Thanks - that's good to hear.

I was thinking this would make a rather nice flower bed and be more attractive than a steeply sloped pile of dirt!

Yes just make sure you have the client see what his local municipality needs before signing the loma fill authorization form. Then you can procred as needed. He might need an engineer or architectural plans. Hopefully not.

In my opinion the loma-f isn't worth the headache nor the money you can charge for it. Sometimes it's smooth, sometimes it's not so much.
