underground storm shelters but the cost is prohibitive..usually well
over $3500.00 . Id like to sink some kind of a waterproof box that
would fit one adult ... approx. 3 feet into the ground , located in
the corner of my garage which currently is very sandy soil.

Rather than a hole in the ground, how about a "safe room" above ground.
Cheaper, DIY, tornado proof. Look for the idea at www.polysteel.com

Actually, an above ground shelter that can withstand a tornado is
generally a *lot* more expensive to build than an underground one. In
fact, the FEMA "taking shelter from the storm" publication shows by far
the cheapest and simplest which is a length of large diameter drain pipe
buried vertically in the ground with a ladder and a cover. My plan is to
bury a 20' cargo container ($1,500 or so), and weld a hatch and some
stairs into it.
