Sure, but groundwater flow has to be accounted for. Hard engineering can lead to very bad outcomes. The Soviets tried to ignore the effects of disrupting thermal equilibrium in their attempts to build cities in permafrost areas. Their solution was prodigious volumes of concrete. It failed badly. These days geotechnical engineers try to work more harmoniously. For example, in areas with saturated soil one approach is to excavate an equivalent weight of soil to that of your construction, thus the building effectively floats, and there is no disruption to the local dynamics. I cannot see that Elon can get around the need for proper geomorphological study here.
