$this->bbcode_second_pass_quote('thuja', 'O')ops sorry- I took a look at those maps but they seem a tad conservative to me...any detailed local studies?
Not that I'm aware of, it's a rather extreme topic after all. Even a 1m rise seems to inundate parts of PDX for some reason, it's actually listed on my topo map at 26ft = ca. 8m. Portland itself is listed at 50ft. There are more detailed online topo maps if you want to see what you're in for.
Even a small rise will wash out airports like La Guardia though. As many point out the chief thing to worry about GW is change in climate, which we seem to be mercifully spared from so far, at least until we say goodbye to all that meltwater.
There are very detailed earthquake maps of Portland, while we're on the subject of disaster. Watch out for that silt! Something else geographical that cracks me up about Portland is the fact that Happy Valley, Pleasant Valley, and Sunshine Valley are all built around volcanic cones - the Boring Volcanos.
