I think it is a troll, as well- why else mention the 3-foot depth of the
posts in the ground?
Read a few books about engineering and flowing water first. First stiff
wind or wind-driven water surge will lay the thing over. 8 pounds per
gallon, 65 lbs per cubic foot (or thereabouts) packs a lot of kinetic
energy. Foot-deep flowing water can knock over a strong man, if it is
moving fast enough. Add in floating debris, and the problem gets even
worse. Debris either acts as a missile, or it build up against the
structure and increases the sail area, loading the structure even more.
Remember, floods also usually come with high winds, other than maybe
spring snow melts.

Unless they have a reinforced concrete structure on a solid foundation,
with an upper floor well above flood stage, only fools try to ride out
an active flood. Even in the coastal areas with raised houses, they
still get the hell out. The blowout panels and raised utility balconies
are just to reduce the damage if the house doesn't get swept away. And
their dozens of pilings go as deep as they can realistically shove them
into the ground.
