New York City Tree Risk Assessments from Level 2 Inspections

Risk Assessments are sub-components of Inspection records where Type = Level 2, detailing tree defects for the Parks' Tree Risk Management program. Each defect is evaluated using three rating variables to calculate a Total Rating, with multiple assessments possible per tree inspection. The dataset is maintained by the City of New York and was last updated in March 2026.

Use Cases

• Analyze the distribution of Total Rating scores across assessed tree defects to identify high-risk patterns.
• Correlate specific defect types with the three rating variables to understand risk factor contributions.
• Model the relationship between multiple Risk Assessment records and their parent Inspection records to assess tree-level risk aggregation.

Strengths

• Data is part of a formal municipal Tree Risk Management program, ensuring a structured collection process.
• Records are explicitly defined as sub-components of Level 2 Inspection records, providing clear data lineage.
• The dataset offers multiple file formats (CSV, JSON, RDF, XML) for user flexibility.

Limitations

• Critical metadata like row count, column names, and data size are unknown, hindering initial assessment of scale and structure.
• The data dictionary and user guide are hosted on external Google documents, which may present access or link stability issues.
• The license is listed as 'notspecified', creating potential uncertainty for commercial or redistribution use.
