California land map: flood, soil & wetlands

California has no statewide parcel layer in LandCheck. The state publishes parcels only as files to download, not as a live map service. Flood zones, wetlands, soil, elevation and protected lands still work there.

Parcels: no statewide layer

The state publishes parcels only as files to download, not as a live map service. In California, parcel lines come from these county and city servers instead: Los Angeles County, San Diego County, Orange County.

Technical detail

No free statewide parcel REST endpoint. The only statewide aggregate (ICE/UC Davis) is a downloadable snapshot, not a live service; ~13M parcels are published per-county (58 counties) or via paid vendors.

If the state publishes a live parcel service, let us know.
