Questions
Which California counties have a page?
All 58 counties in California have a page here, each with its FEMA flood map, parcel lines, zoning office and soil survey.
Who zones land in California?
Each county zones its unincorporated land, and each city zones the land inside its own limits. The planning or zoning office has the district for one lot.
Where do the California parcel lines come from?
From the California county parcel layers (each county publishes its own). Mapped lines are approximate; a licensed surveyor sets the true corners.
