NYC Environmental Zoning Designations for Tax Lots

E-Designations provide notice of environmental requirements for hazardous materials, noise, or air emissions on specific New York City tax lots. The dataset includes zoning map references, tax lot and block identifiers, and CEQR numbers. It is maintained by the New York City Department of City Planning, with a current version from November 2025.

Use Cases

• Identify tax lots with hazardous material concerns by querying the DESCRIPTIO field for contamination-related terms.
• Analyze the spatial distribution of noise or air quality requirements across boroughs using the BOROCODE and geometry columns.
• Link environmental designations to specific zoning actions or projects via the ULURP_NUM and CEQR_NUM identifiers.
• Join with other property datasets using the BBL (Borough-Block-Lot) or TAXBLOCK and TAXLOT fields for comprehensive site analysis.

Strengths

• Includes geospatial coordinates (geometry column) for mapping and spatial analysis.
• Provides multiple unique identifiers (BBL, TAXLOT, TAXBLOCK, ENUMBER) for data linkage.

Limitations

• Sample data and total row count are unavailable, preventing assessment of dataset scale.
• Specific license terms are not provided, which may restrict commercial or redistribution use.
