Connecticut Steep Slope Areas Derived from 2-Foot Resolution Lidar

Steep Slope 2 ft is a geospatial feature service from the State of Connecticut's Office of Policy and Management. It maps areas with significant slope gradients across the state, derived from a 2-foot per pixel Digital Elevation Model created from 2023 Spring imagery and lidar capture. The dataset includes attributes such as slope percentage category, municipality, and council of governments region.

Use Cases

• Assess terrain steepness for land development planning based on slope percentage categories.
• Conduct high-resolution terrain studies for environmental management based on the 2-foot pixel resolution.
• Map slope stability risk areas for municipal planning based on municipality and COG region attributes.
• Support infrastructure planning by identifying very steep slopes (20%+) across the Connecticut landscape.

Strengths

• Derived from a high-resolution 2-foot per pixel Digital Elevation Model.
• Includes specific slope percentage categories: Moderate (10%-15%), Steep (15%-20%), Very Steep (20%+).
• Data creation date is explicitly stated as 2026.
• Source lineage is documented, tracing back to the 2023 Spring lidar capture.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation beyond the three listed attributes is absent; field semantics must be inferred after download.
• Update frequency is listed as 'none', indicating the dataset is static.
