SDOT.V SU Permit Use Impacts: Seattle Street Use Permit Impact Line Segments

Seattle Department of Transportation (SDOT) data modeling relationships between street use permits and impacted street line segments. The data model connects permit points to dissolved and component use impacts, enabling easy identification of all impacted segments for any permit. The dataset is updated nightly and is constructed for use in the Right of Way Map.

Use Cases

• Visualize all street segments impacted by a specific permit based on the permit-to-impact relationship model.
• Analyze aggregated permit impacts across the city based on the dissolved use impacts feature class.
• Drill down to inspect specific use impact details for a given permit based on the component use impacts feature class.
• Integrate permit impact data into a Right of Way Map for operational planning.

Strengths

• Data model explicitly defines relationships between permit points, dissolved impacts, and component impacts.
• Update frequency is nightly, suggesting regular data refresh.
• Data is constructed for a specific operational tool (Right of Way Map), indicating practical application.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
