Coverage

Live in 37 counties across Texas, California and 8 other states, focused on the strongest markets. Need another area? Contact us.

37 counties across 10 states. The number on its own would overstate what most of them can answer, so the depth is stated first.

Interconnection depth

Parcels, zoning and national constraints, plus published circuit-level utility evidence — hosting capacity, substation capacity, distribution geometry.

Screening depth

Parcels, zoning and national constraints. For most of the footprint this is the honest ceiling rather than a lesser version of the above — no utility publishes circuit-level capacity there, so there is nothing further to load.

How current the data is

Data imported 61–72 days ago · re-ranked 60–61 days ago. County data is re-imported by hand when we rebuild a county — not on an automatic schedule. Between imports, a read-only check runs weekly against every county's upstream sources and alerts us when one goes down, is withdrawn, moves behind a login or shrinks, so a source that breaks is noticed within about a week. It does not detect a publisher simply releasing newer data; that arrives only when the county is next re-imported. When a county is re-imported it is re-ranked from the new data rather than carried forward — so a parcel that stopped qualifying stops qualifying here.

The same discipline, on ground nobody mapped

Mapped in two quadrangles. Unevaluated in 681.

California's Geological Survey publishes mapped liquefaction hazard zones. Across the bounding boxes of all eight California counties GridCite covers, those layers map zones in two quadrangles, in one county — Yolo — and no earthquake-induced landslide zone anywhere in the eight.

Wire that layer into a map on its own and it prints a clean reading over seven counties. A developer sees no hazard zone and moves on.

The reason is in the Survey's own companion layer — the one that maps the areas nobody has evaluated for liquefaction or seismic landslide. Over the same eight bounding boxes it returns 681 unevaluated quadrangles, between 45 and 192 per county.

The state has largely not looked. That is a different answer from “no hazard”, and it is the answer that should reach the reader.

Measured against the live California Geological Survey services over each county's own bounding box on 2026-08-10, and independently re-derived: Kern 88, Fresno 192, Tulare 108, Kings 48, Colusa 45, Yuba 49, Yolo 52, Merced 99 unevaluated quadrangles. Counted by quadrangle rather than by polygon on purpose — the mapped zones are three polygons of 146, 0.09 and 0.045 km², so a polygon count would make 146 km² of mapped ground sound like nothing. Recorded in docs/legal/DATA_RIGHTS.md and PR #496.

The same ground, two ways of reporting it

Zone layer alone

Liquefaction zone: none

True to the layer. Read as a clean site. Wrong.

GridCite

Not evaluated by the state

No hazard mapping has been performed over this quadrangle. That is a question for a geotechnical scope, not a clean screen.

Not seeing your market?

Coverage is added county by county, and which counties come next is driven by what people ask for. Tell us the county and the project type and we will tell you honestly whether the data exists to support it — for some markets it does not, and we would rather say so than add a county that answers nothing.

Depth is derived from the evidence actually loaded per county, not from a maintained list. Scoring version 3.1.0, screening rules version 1.10.0. A county showing an older figure for either is live but ranked and screened by an earlier rulebook until it is rebuilt.
