Name: Preliminary Alluvial Fans
Display Field: DFIRM_ID
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Location and attributes of alluvial fan studies. Only the 1-percent-annual-chance flood is mapped for alluvial fans. The alluvial fan could be mapped as: Zone AO areas with depths and velocities; Zone AO areas with just depths; or Zone A, AE, or X. This information is needed for the Summary of Alluvial Fan Analyses and Results of Alluvial Fan Analyses tables in the FIS report.
