@duane we sit at +230 feet over MSL. The ground the house is on is alluvial gravel. SO, no liquefaction or sinking. Prior to purchase I ran thru all the USGS records, the Mortgage Insurance agencies (they worry about stuff) local FD Community Right to Know records and checked with the FAA. We have still had 3 GA aircraft crash in the neighbor hood, thank the Lord - no C-17s or C-130s.... If it really gets bad, my fallback is to get on the FTS and haul ass. We keep bags pack for just that instance.
