Name: ca_Steep_Slope_Classes

Display Field: slopeclass

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This layer depicts classified slope gradients derived from 2015 high-resolution elevation data obtained from Quantum Spatial. The data has been processed to remove noise from manmade features such as retaining walls, curbs, ditches, and other surface obstructions, ensuring that only natural terrain slopes are represented. This layer is used extensively in geohazard assessments, site development planning, and regulatory review, helping to identify areas of steep terrain where landslides, erosion, or development constraints may exist.
