California — land-transition accounting + a CEQA-stage LESA pre-screen.
Pick a place and a pair of survey cycles: read the ledger of what its farmland became — acre by
acre, class by class — and score what the next project would cost.
Every transition is a real per-field join on DWR/Land IQ's stable UniqueID
across two statewide crop surveys. No geometry is intersected and no acreage is modelled.
The California LESA Model (CDC 1997, per SB 850) is computed live from USDA SSURGO
(Land Capability + California Revised Storie Index) and the survey itself. Every factor prints its source.
This is a screening and accounting tool — not a determination of significance, not a system
of record, and not an observation. The lead agency determines significance.
The app never says "converted". It says which survey classed a field what, in which year.
