San Francisco Archipelago Posters

Urban Life Signs and Burrito Justice have teamed up to bring a refined, high detail San Francisco Archipelago Map for you. It's official. You can get your very own San Francisco Archipelago Map poster on Zazzle.com. The lovely maps showing what San Francisco would look like if sea level rose 200 feet.

Burrito Justice has also produced an AP article update. Check it out over at Burrito Justice. If you'd like to see a more likely sea level rise map,  the 25 foot sea level rise map of SF is here.


You can get the map in three sizes:

24"x24" - $29

16"x16" - $20

12"x12" - $15

Here's a closeup of northeast San Francisco where Telegraph Hill becomes Telegraph Island, and the Western Addition becomes Divisadero Harbor.


The fun doesn't stop there. We'll be producing neighborhood maps, gradually. A rough cut of the Bernal/Glen/Noe area is in current production.

  1. Like the Map but they should overlay the geology maps so they can remove any alluvial and silt deposits through tidal, water flow and storm surge action.

    It gives you Bays and Harbors where you least expected them - in the end you will wind up with cliffs and swamps.

    1. Where would one find such a geological map? Do you have one in mind?

      Regarding alluvia deposits, I imaging that over time Dolores Cove could silt up and form a marsh or small delta, but that only assumes there's enough alluvial deposits to create a marsh - plus it would take time. Islais Bay, Marina Bay, and possibly South Basin could fill with some deposits as well, and they might not be washed away since they would be on the more protected bay side.

      The biggest wave action target would be Ocean Beach. I don't imagine that Cape Judah and the Great Lagoon would last long, but you never know. Maybe there would still be enough sediment from the Sacramento/San Joaquin rivers to produce sand for such a cape.

      Where do you think marshes, lagoons and wave erosion would have the most dramatic affect?

    2. CORRECTION - I was commenting on what affects would happen with a 25 foot sea level rise.

      Regarding alluvial deposits and wave erosion for the 200' rise, the primary areas of interest would be silting up of Bay of Castro and Divisadero Harbor. Wave erosion could really impact the Pacific coast, especially from Cape Judah to Merced Shoals. Wonder if enough wave erosion would break into the sinks at Stern Grove which would are dry on this map, but under sea level.
