Frequently asked questions
The valley is dry most of the year. When does the water actually arrive?
In a few atmospheric-river days, usually in January. The rest of the year teaches the ground and the drains nothing. Hardpan sheds the first storm, creeks that have been dry since April fill in hours, and a raised crawlspace over clay fill can stay wet for weeks after the sky has cleared.
What does liquefiable fill have to do with a leak that is not a quake?
The same fill that can liquefy is a poor drain in ordinary weather. Bay-margin clay holds water against a crawlspace or a slab edge. A plumbing leak or a January storm then sits in material that will not let it down, which is why the older core stays damp longer than the alluvial fans toward the hills.
Is a slab from 1976 better or worse than a crawlspace here?
Different failures. A slab hides a supply-line leak until the flooring or a baseboard shows it. A crawlspace shows the water and also sits over clay that never fully dries. Neither assembly was built with a capillary break that this valley's fill actually needs.
