I never heard of Oak Glen before, but do recognize the mountain names. I wouldn't expect to find any towering Sequoias and Redwoods there because neither species is native to that part of California, and they do take some time to become towering. And I've never heard of any overlapping of their ranges. A more suitable house for this location might get inspiration from the Monolithic Dome in Yucaipa which survived a direct hit from a wildfire.
