New York City Zoning Applications Since 1970s

Zoning Application Portal data from the NYC Department of City Planning tracks land use applications. It contains information on approximately 30,000 projects processed since the late 1970s. The dataset includes project tracking and description data for applications that have been noticed or filed.

Use Cases

• Analyze application processing timelines by correlating validated_date with project status.
• Map zoning application density by borough using validated_borough and bbl (Borough-Block-Lot) fields.
• Identify data validation patterns by comparing validated_block and unverified_block columns.
• Track project history and status changes over time using project_id and validated_date.

Strengths

• Approximately 30,000 project records provide a substantial historical sample.
• Data covers a long temporal range from the late 1970s to present.

Limitations

• Sample data is unavailable, preventing assessment of data completeness or value distribution.
• The presence of unverified_block and unverified_lot columns suggests potential data quality issues requiring verification.
