Service Description: The National Structure Inventory (NSI) provides a base national dataset of structure points and characteristics. Using the NSI, USACE engineers, economists, and others can generate improved estimates of flood risk through HEC-FIA, HEC-FDA, HEC-WAT, CWMS, and HEC-LifeSim. The NSI is a particularly helpful resource for teams in the early iterations of a Planning study. Though it is anticipated the NSI data will be updated at least annually, teams should note the data's limitations, including the need for population and price index adjustments before use.
