How exciting!
My grandparents had a place just across the border to the south, far inland from Crescent City, which had madrone but also conifers. My grandfather's orchards did well, but I seem to remember berries being very important too. I remember him telling me what good wood madrone is, when I was very young.
I've read white oak produces the tastiest acorns, so that is one staple crop fewer to worry about. It's probably worth looking into dry-season methods of removing the tannins: I could imagine circulating water through acorn meal, then charcoal, would improve both the food and the soil amendment. Maybe it would be worth hedging your bets with an un-related staple like piñon pine: perhaps the Colorado piñon?
It sounds like ramps would do well there, as well as mushrooms. Especially if you decide to keep bees there, and worry about them finding food in a particular season, I recommend Paul Stamets' brief article
Permaculture with a Mycological Twist: the right mycelia in a hugelkultur bed, and a hole dug to expose them at the right time, would keep a hive very well-fed at times of year when local vegetation isn't diverse enough to supply nectar.
I could imagine using termites to feed fish, the way Sepp Holzer uses ants. There are also simpler aquatic creatures you might keep: I remember crayfish doing very well in that climate, and I hear they are easy to care for.
Is there claytonia (like miner's lettuce) on the property? It might be a good genus to encourage or introduce.
