Judging from that discoloration around the window, it looks like it
might be LP siding, not HardiPlank. Around 1995, in the Seattle area,
you would have been much more likely to have someone sell you LP versus
HardiPlank. All the mushrooms growing out of the LP - and the
resulting class action lawsuits - are one of the reasons HardiPlank has
become so popular in the Northwest.

If it feels almost as hard as cement, it's probably Hardi. If it
feels like you could almost push a nail through it with your bare
hands, it's probably LP. Either way, it almost certainly contains no
asbestos. If you do have LP (or some other pressboard product) make
really sure to maintain the flashing, caulking, and paint. The stuff
can't take much exposure to water.
