NYC Coastal Flooding Resiliency Exposure Forecast for Planned Adaptation Projects

The Resiliency Exposure Forecast for Coastal Flooding evaluates how planned neighborhood-scale protection projects could reduce building exposure to storm-surge and tidal flooding in future decades. This dataset from data.cityofnewyork.us compares a Control Scenario against a Planned Action Scenario, quantifying the number and percentage of buildings at risk. It was last updated on May 19, 2026.

Use Cases

• Compare building exposure under different adaptation scenarios using Scenario_Name and Scenario_Code.
• Analyze risk distribution across neighborhoods using NTA_Code, NTA_Name, and NTAAbbrev.
• Calculate the proportion of buildings protected by planned projects using Count and Percent columns.

Strengths

• Explicitly defines two future scenarios (Control and Planned Action) for comparative analysis.
• Provides neighborhood-level granularity via NTA_Code and NTA_Name columns.
• Includes both absolute Count and relative Percent metrics for risk assessment.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
