-I've been thinking about building on my lot in the Hawaiian Beaches
area. Years ago I hand-cleared part, but had the future house pad area ripped and leveled with a D9 dozer.
Is the usual building code for a two-story house footing of 18" below undisturbed soil required for the lava rock in much of Puna? My design is for a large garage slab with 2nd floor above.Also, is it easier and/or cheaper to build the stem wall with concrete block, or formed for concrete pumping? ( Seems like the hard part would be staking the forms.)
Experience and knowledge much appreciated. Mahalo!
