Burn Probability

Fire probability details for property, such as percent chance of burn for a given year, and flame/ember projections.

FirstStreet
GraphQL

A comprehensive GraphQL API that provides forward-looking risk assessment data for properties. Using property data from Lightbox (DMP), FirstStreet delivers detailed projections for flooding, heat stress, wind damage, and air quality metrics projected up to 30 years into the future. This enables portfolio managers and property stakeholders to make data-driven decisions based on climate risk factors.

Air Factor

The property's Air Factor, a numeric integer from 1-10 (where 1 = minimal and 10 = extreme) based on risk to the building.

Flood Risk

Risk likelihood (% probability) for flooding to the building footprint broken down by depth threshold and cumulative year.
