Crawlspace clearance?

[Karl E. Gerhauser]

Does anyone know the reccommended spec for dirt to joist and dirt to floor. I know tis is too tight but I can't locate the #'s for my report. This one is 4" to joist and 14" to floor.

[*]12 inches between beams and the soil below[*]18 inches between joists and the soil below[*]6 inches between support post bases and the soil below
Efforts should be made, such as grading and/or removing soil, to maintain these clearances. If this is not practical, then installing borate based Impel rods may help to prevent infestation and damage.

That's for untreated wood.
