Which East Bay cities actually flood?
Not all of them, and saying so matters. Antioch floods in two named streets. Pinole Creek has put water through downtown Pinole for well over a century. Brentwood has no known principal flood problem, and that is worth saying.

Why name cities at all?
Because inventing the same risk everywhere makes a page useless.
A guide that warns every reader about flooding has warned nobody.
The useful version says which ground has a record and which does not.
Saying a city has no known problem costs something to write, and it is true.
What happens in Antioch?
Two named streets, and that is the published extent.
Antioch has a flood history that sits on a short list of locations.
Which is more useful than a citywide warning nobody can act on. Street water that never reached your floor does not need us.
If your address is not on that list, the risk is a different one.
What about Pinole?
Pinole Creek has flooded the downtown for well over a century.
Pinole carries the longest single record on this list.
A creek that has done it repeatedly is the clearest kind of warning.
Downtown is the part that floods, not the whole city.
Is Brentwood really clear?
No known principal flood problem, and that is the answer.
Brentwood is on this list because somebody there will search for it.
The honest answer is that the risk does not sit where people expect.
Which does not mean a pipe cannot fail. It means the ground is not the source.
Where does water come from instead?
From below, on an island, and from pipes everywhere.
Alameda is the measured case, where the shallow table already sits near the surface.
Elsewhere the ordinary causes carry the day: a supply line, a heater, a stack.
Which is why a flood map is a poor substitute for a meter.
Does a map settle my risk?
No. Plenty of paid losses sit outside a mapped zone.
Sitting outside a mapped zone is not the same as sitting dry.
A homeowners policy does not stand in for it, because flood is not one of its perils.
It gets sold separately, outside that form entirely.
What do I do on the day?
Photograph the line before anybody reaches for a towel.
Storm water leaves a height on the baseboard and on the garage wall.
One pass with a towel erases what a scope gets written from weeks afterward.
Then cut power to whatever circuits the water found.
Is it the city's drainage?
Sometimes, and that call is free to make.
Water that only shows up in a storm is often a drainage problem rather than a building one.
Learning that on this page costs less than learning it from a bill.
Storm work covers what happens when it is not.
What does looking cost?
Nothing, in any of the twenty-four cities.
A technician comes, reads the material, and names what is genuinely wet.
Where the answer is one fan and three days, that is what you get told.
This ground asks more than one page holds, so read the guides.
Where will we not invent a risk?
Brentwood. The record shows no principal flood problem and we say so.
Pittsburg carries only minor reports. Telling an owner their address is clear is worth more than a policy sold on a map nobody checked.
