Texas Water Development Board Cursory Floodplain Dataset (100 Year Recurrence)- 2025 Texas Flood AOI
hydrosphere NASA VEDA COG
In plain English

What it measures. A floodplain map showing where flooding is expected on average about once every 100 years across the area affected by the 2025 Texas flood.

How it's made. Drawn from the Texas Water Development Board's cursory floodplain modeling for the region.

How & where you'd use it. Helps responders and planners identify higher-risk flood zones for response and recovery.
