Parent Layer: Landslide Hazards

Name: Slope (10% or more)

Display Field: AREA

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Areas of land with slopes equal to or greater than 10 percent, derived from the 2019 Metro Lidar Project bare earth digital elevation model (DEM). The lidar data were acquired by NV5 and processed by GeoTerra, Inc. under contract to Metro. GeoTerra created a 3-foot bare earth DEM meeting USGS Quality Level 1 (QL1) standards with a vertical accuracy of less than or equal to 10 cm RMSE(z). The slope polygons were generated by Metro using ArcGIS Pro Spatial Analyst tools and custom Python (ArcPy) workflows. The same 2019 DEM used for the Contours (two foot interval) and Slope (25 Percent) datasets served as the source elevation model, ensuring consistency across all elevation-based layers.
