How it works
From your location to a decision-ready report.
-
Desktop assessment
We screen your location remotely against hazard maps, hydraulic models and the hydro-database. You send a location; no site visit is needed.
-
Site verification
On Premium assessments our team confirms conditions on the ground and checks the desktop findings.
-
Report
You receive a written report, from a 2-page screening to a full assessment, with a risk rating for current and future climate.
-
Expert consultation
Standard and Premium packages include a 30-minute or 1-hour session to walk through the results and recommendations.
Flood risk intelligence
From hazard identification to exposure and vulnerability.
Current and future climate scenarios across multiple return periods, mapped for populations, assets and critical infrastructure.
Return periods
5y
10y
20y
25y
50y
100y
Pluvial flooding
Direct rainfall-induced surface water flooding and urban ponding.
Fluvial flooding
Riverine flooding from overbank flows and catchment runoff.
Dam release flooding
Inundation from controlled releases and dam breach scenarios.
Coastal flooding
Storm surge, tidal flooding and shoreline retreat dynamics.
Flood Risk Intelligence Reports are delivered in days, not in months, so the answer arrives while the decision is still open.
Solutions
Flood risk assessments, packaged in three tiers.
Every tier is a desktop assessment; Premium adds a site visit and future climate scenarios.
Home Buyer Flood Risk Assessment
An independent, clear assessment of flood risk for any residential property, so you can buy with confidence and avoid costly surprises.
