Here’s My Favorite SF Liquefaction Map

This being earthquake country, it’s important to know what sort of ground lies beneath the home you own or are planning to purchase. In San Francisco, there are liquefaction zones, which are essentially landfill and are not recognized to be as stable. I’ll let Wikipedia explain it in more detail here.

Yes, people are buying and selling property all the time who live in what are deemed liquefaction zones. Some of the most popular neighborhoods, in fact, are those which are very much a part of these zones. Think the Marina, North Beach, South Beach, Mission Bay, South of Market, and the Mission. But that factor isn’t stopping developers, who are building new condo developments at a frenzied pace in the last four of those neighborhoods.

That’s because the more modern the building, the better the engineering. Properties built more recently are designed to withstand large earthquakes, particularly those properties situated in liquefaction zones. Of course, if the big one hits, it won’t be just homes in liquefaction zones that are affected.

So be sure you have some idea as to the quality of your foundation and your home’s overall structure. And check out the liquefaction map when you need it for a reference point. View and download it here.
