Why cannot the IMP do subterranean parking, or off site parking.
Partly because once you cut deep enuf you run into the marshlands that were there for ages making for various instability issues, etc., and there's aquifers that would be disrupted. Probably some zoning and other restrictions as well, plus Hawaiians usually have their issues with futher diggings.
