Name: Slopes 20% or greater (LiDAR)
Display Field: Is_Water
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: Polygons representing slopes greater than or equal to 20% in the Portland urban services boundary area. Derived from 2014 3' resolution LiDAR bare-earth digital elevation model (DEM). All slopes average over a horizontal distance of 15'. Minimum area of contiguous slope is approximately 1/2 acre. Polygons were created, generalized and smoothed in ArcGIS 10.3.1.
-- Additional Information:
Category: Land
Purpose: For identifying steeply-slope areas within Portland.
