I have a great listing currently for sale at 1487 Chestnut Street (corner Gough & Chestnut) here in San Francisco, and of the 50 or so people I actually had the chance to speak with at yesterday’s Open House, all of them (not kidding) asked if this property is built on landfill, and thus in an area of liquefaction.
Since this is clearly an area of concern for many people, I did a little digging on some of the maps I’m able to access, as well as a few more, and was able to layer the MLS district map over the liquefaction map, capture the image, and I’m sharing it with you to satisfy your curiosity. As you’ll see, contrary to popular belief, the entire Marina District (in purple) is not all landfill/liquefaction.

There you have it. If I helped you win a bet, you’re welcome.
I’ve done a fair bit of research about earthquakes, liquefaction zones, and earthquake induced landslides areas in San Francisco and have shared it all over the years, the links which you can find below. As for the Marina District, now I gotcha covered there too.

[BIG ASS DISCLAIMER! I AM NOT AN EXPERT ON EARTHQUAKES, LANDFILL, OR LIQUEFACTION, I AM ONLY SHARING MY RESEARCH WITH YOU, AND IF YOU ARE REALLY CONCERNED ABOUT THE LOCATION OF YOUR PROPERTY OR ANY ISSUES REGARDING EARTHQUAKES AND LIQUEFACTION YOU SHOULD CONSULT WITH AN ENGINEER OR EXPERT IN THIS MATTER.]
Great information. I’m sure this will ease the minds of many with an interest in your listing.
This is awesome. There needs to be maps like this across the country for all zones subject to the forces of mother nature. Thank you for providing this valuable service. Building codes and building design should reflect the nature of the areas they plan to exist in. To ignore the forces of nature or gamble against her is a losing proposition.
you might be a mile from a liquefaction zone, and when the homes in the liquefaction zone all burn from broken gas lines, that fire may consume your home as well. See what happened in 1989 and 1906. It will happen again.
