Property Elevation

Determine the property elevation to compare with the local base flood elevation.


Property Elevation is essential for determining flood risk, and in areas like coastal Florida the elevation must be very accurate. National Flood Data uses the Clockwork Micro Elevation API. The Clockwork Micro Elevation API provides data from the United States Geological Survey's 3-D Elevation Program. National Flood Data previously used the USGS's Elevation API, but this service often had outages. Clockwork Micro provides the same data with a faster response time and excellent uptime reliability.

Insurance companies in coastal Florida have been using this the elevation data that we provide since 2019 and have found it to be very accurate. It has been tested in areas where one foot makes a difference, and users have found that they can rely on this source.
