Glad to hear you are on board; it is odd, I live about 6 blocks from the beach about 60 ft above sea level; Sacramento is 100 miles inland at 11 ft above.
The problem about building else where because of potential disaster is this. No where is safe. Case in point lets get off poor old San franscico. THere is a major fault line called the NEw Madrid fault. The last time it went off French Explorers recorded that the Mississippi River ran backwards for two days. Now it will go off again this not fantasy. IN fact it prob will go off in our lifetime/ Everyone knows it. However despite that building just proceeds its merry on way along the fault esp in Memphis. Now the big one hits and St LOuis and Memphis among hundreds are decimated. Shall we rebuid? Of course. The smae for San Franscisco and the surrounding areas. We just build better.
