Field notes
The page groups counties into five answers, ranging from “No soluble rock mapped” to “Sinkhole country,” and gives examples including Harris County, Maricopa County, Los Angeles County, Dallas County, and Miami-Dade County. Its checklist points readers to state geological-survey sinkhole maps and parcel records for past claims or repairs; it also notes that a home inspector cannot see below a slab.
