Name: SB3 Flash Flood Risk Areas - Median DV Urban BLE

Display Field: FFRA_Grid

Type: Table

Geometry Type: N/A

Description: FFRA_Grid: This is a foreign key that relates to the Unique_ID field in the FFRA_Grid table. med DV class_Urban_BLE: Indicates the median flood severity category calculated for buildings within the 500-year floodplain, using the maximum depth-velocity product from available BLE models. This data is only available within Bexar, Travis, and Williamson counties, where the flood severity category may range from 0 to 5, where 5 represents extreme flood severity. Outside of these counties, pixels will have the default value of NULL.
