Anyway to Avoid Flood Vents in Flood-Prone Area?
(OP)
Architect and Owner are insisting on NO flood vents in foundation walls (stem walls). House is in AE zone. I have scoured ASCE 24, FEMA bulletins, is there any responsible way to do this? Cost is not a problem.
thanks in advance, the rattler

No way around it that I know of. Or move to higher ground.

You did say price was no object, right?
I would also encourage you to consider a water-tight concrete admix, such as Crystal or Xypex.
Hope that helped,

RE: Anyway to Avoid Flood Vents in Flood-Prone Area?
I appreciate the prompt and thoughtful replies. Part of my confusion comes from this: I've estimated the hydrostatic loads, based on the BFE against the foundation walls. It seems to me the loads are fairly meager, meaning a reinforced masonry wall, with some shear-wall type walls behind it, could easily resist the forces. If this is true, the requirement for flood vents seems a bit excessive. I respect the technical bulletins from FEMA, so where am I going wrong?
thanks in advance

have you included any impact from debris?
have you considered the anchoring required to keep it from floating?
