We were walking along the Embarcadero in San Francisco when we came upon this. The Embarcadero is where you embark. Once upon a time that meant getting aboard all kinds of ships. Today that means boarding a ferry to take you across San Francisco Bay.
The whole point of building (and rebuilding, and maintaining) the Embarcadero was to let you keep your feet dry while walking to the dock and stepping aboard the boat. As you can see, that's not working so well any more.
That fence between us and the splashing water is a recent addition. Behind it is a set of stairs that used to descend to sea level so you could tie up a small boat, step out of it and walk up to ground level. The city fenced off the stairs because now it's a rare day when more than two of them are dry.
To be fair, this picture was taken on a day when we had a king tide, defined by Wikipedia as ", , , the highest tides. They are naturally occurring, predictable events." So the Embarcadero is not like this every day. On the other hand, this is now predictable.
