Layer: Present_Day_Chronic_Inundation

View In: Map Viewer

Name: Present_Day_Chronic_Inundation_PA

Display Field: SCENARIO

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description:

This layer represents the chronically inundated area for the present day. The chronically inundated area is defined as the area the floods 26 times per year or more. Note that inundation within leveed areas may not be well-represented due to limitations in the underlying elevation datasets.
