Hi Guys,
I had a customer request that I design an independently supported deck for their front yard, the issue is that there is a leach field that parallels the house 10’ away. This is where the outside of the footings will be. The county has setback requirements saying “all buildings or manufactured homes must be at least 10’ away from Septic Tanks and Leach Fields.” But the building official gave them my card and asked them to see if I was ok with footings there.
That being said, this seems like a bad idea for several reasons. But I was hoping to find some guidance for this in the IRC or IBC, seems like crushed stone below the footing and a lower allowable soil bearing pressure would be OK provisions. Does anyone have any thoughts, experience or literature they can reference to educate me? I did tell the client there’s a chance that he won’t be able to do this, but let me do some research first.
TIA!
