Im across the canyon in Foresthill! There is a farmer off of Gold Hill Rd in Placerville, has an honor stand and could tell you a bit about growing. Probably more farm than permaculture though.
I can't wait to build my pond!
And if you need green building supplies, SONS in Grass Valley: Hemp oil stain, Cotton insulation etc and next door to them is Sierra Solar with all kinds of solar and alternative power goodies and books

Hope we cross paths some day!
