AAL Calculator

Average Annual Loss Calculator

NOTE: These optional parameters only apply for the property location type.

NOTE: When appending custom "depths" only the depthLoss node is impacted. For all other parameters, the parameter appended will adjust calculations for both depthLoss and annualLoss.

The AAL API accepts optional parameters to impact the AAL calculation. If no parameters are appended, it will provide the AAL costs based on the default values that First Street Foundation has available from 3rd party data providers or calculations.

(More information on the Average Annual Loss calculator can be found on the Calculator Page on the First Street Foundation API Data Dictionary)
