As I zip around Sacramento via various modes of transportation, I see a cryptic sign all over the place. Since my last post on the railroad spur brought such a wealth of information, I’d like to tap the collective knowledge of Sacramentans once again.

The sign is a circle, with one half painted orange and one half painted green. They invariably show up in the vicinity of things that seem flood-controlish: near the railroad gates at 19^th & C. Near the gates at Del Paso under 160. At various points along various levees.

Does anyone have any idea which agency is responsible for these pictograms, and what exactly they signify? Or are they omens and portents of the coming apocalypse, a la the Low Men in Yellow Coats?
