Walk to a Park Service Area for CEQR Open Space Assessment

New York City provides a geospatial dataset modified to support Open Space assessments under the City Environmental Quality Review (CEQR) Technical Manual. The data identifies tax lots considered within walking distance of a park, defined as 1/4-mile for small sites or 1/2-mile for larger parks over 6 acres, supporting the OneNYC 2050 goal of 85% of residents living near a park by 2030. It is used to calculate park access metrics for the Mayor's Management Report, focusing on under-resourced areas and excluding non-recreational spaces like cemeteries.

Use Cases

• Assessing compliance with open space requirements for development projects using the Area and polygon columns.
• Mapping park service gaps for equity analysis using the polygon column to identify underserved tax lots.
• Supporting CEQR Technical Manual Open Space assessments by analyzing which lots are served using the modified tax lot logic.
• Tracking progress toward the OneNYC 2030 park access goal by calculating population within service areas defined by the polygon column.

Strengths

• Explicitly supports a major city policy goal (OneNYC 2050) with a defined target of 85% resident access by 2030.
• Provides a clear, rule-based modification for tax lot inclusion (if 50% or more of a lot is within a service area, the entire lot is shown as served).
• Includes publicly accessible parks not under NYC Parks jurisdiction, likely providing a more complete picture of recreational access.

Limitations

• Key metadata such as row count, license, author, and precise data dictionary URL are missing from all sources.
• Data accuracy is explicitly noted as limited by the scale and accuracy of the original secondary sources used in the analysis.
• The last updated dates conflict between platforms (2026-05-26 on Socrata vs. 2026-04-12 on Data.gov), creating uncertainty about freshness.
