What the product does
One report, every hazard that matters for SoCal due diligence.
GeoScreen pulls the public agency maps for a Southern California address into one preliminary screening — so you can triage a property before you spend hours on manual research. Explore what each report covers, then see the specific hazards we screen.
What the product does
Instant address screening
Type a Southern California address and get a sourced preliminary screening in minutes. GeoScreen resolves the address to its parcel where county data is available, then checks that parcel against the public agency hazard maps — so the legwork that used to take hours of manual map-pulling is done for you.
A shareable PDF report
Every screening produces a clean, standardized PDF you can forward to clients, partners, or lenders. Each finding cites the agency dataset behind it, and every page carries the screening-only scope so the reader knows exactly what the report is — a preliminary due-diligence aid, not a professional geologic report and not a Natural Hazard Disclosure.
Six-county Southern California coverage
GeoScreen screens addresses across Los Angeles, Orange, Ventura, Riverside, San Bernardino, and San Diego counties. Enter an address outside these counties and the product tells you plainly — no credit is charged — and lets you join the waitlist for new coverage.
Fast pre-offer triage for many properties
Built for real-estate professionals who evaluate a lot of properties, GeoScreen uses a simple credit balance so you can run one address or a whole list. Paste your addresses or upload a CSV, and each one becomes its own full screening report — then read them side by side in one table and export the results. Addresses we cannot locate, or that fall outside our six counties, are refused before any credit is used. Use it for fast pre-offer triage — surface the factors worth a closer look before you commit time to deeper diligence. The product flags where further professional investigation may be warranted; it does not rank or score properties.
What each report screens
Active fault proximity
GeoScreen checks whether a parcel falls inside a state-designated Alquist-Priolo Earthquake Fault Zone and reports its proximity to mapped active faults. The screening tells you what the California Geological Survey fault data shows for that location, with the data source cited, so you know whether fault rupture is a factor to investigate further.
Seismic shaking & ground-failure zones
Using the California Geological Survey Seismic Hazard Zones, GeoScreen reports whether a parcel intersects an official Zone of Required Investigation for earthquake-induced ground failure. The screening surfaces what the state seismic data indicates for the parcel — a flag for further investigation, not a structural assessment.
Liquefaction zones
GeoScreen checks the California Geological Survey liquefaction Zones of Required Investigation to report whether a parcel sits within a mapped liquefaction zone. The result reflects what the official state data shows and cites that source; it does not assess soils on the parcel itself.
Landslide zones & inventory
GeoScreen checks both the state earthquake-induced landslide Zones of Required Investigation and the mapped landslide inventory to report whether a parcel falls within, or near, a mapped landslide feature. The screening reports what the agency landslide data indicates for the location, with the source cited.
Slope & terrain
Using public USGS elevation data, GeoScreen estimates the slope and terrain across a parcel. Steeper terrain is one of several factors a professional may want to examine, so the screening reports what the elevation data indicates — the estimate is preliminary and best-effort, never a stability determination.
Wildfire severity zones
GeoScreen checks the CAL FIRE Fire Hazard Severity Zones to report whether a parcel falls within a state-designated severity zone, and which designation applies. The screening reports the official CAL FIRE designation for the location with the source cited — it reports the state map, it does not predict a fire.
Flood & debris-flow exposure
GeoScreen checks the FEMA National Flood Hazard Layer to report whether a parcel intersects a mapped flood hazard zone, and surfaces a best-effort debris-flow proximity flag drawn from public post-fire data. The screening reports what the federal flood map shows, with the source cited; the debris-flow flag is a proximity indicator, not a determination.
