PPRI Oise Valley: Natural Hazard Risk Zoning for Land Use Planning

A 2021 geospatial dataset from the French Geological Survey (BRGM) delineating areas exposed to natural hazards within the Oise Valley study perimeter. The data results from hazard studies assessing the probability and intensity of dangerous phenomena, used for regulatory risk prevention plans (PPR). It includes zones protected by structures, which are still considered subject to hazard.

Use Cases

• Modeling flood or landslide risk for construction permits based on hazard intensity zoning.
• Assessing land value and insurance premiums based on regulatory hazard exposure levels.
• Planning emergency response routes by identifying areas with high probability of hazardous events.
• Evaluating the effectiveness of protective structures in hazard mitigation planning.

Strengths

• Produced by a national geological survey (BRGM), suggesting authoritative sourcing.
• Includes areas behind protective structures, reflecting a conservative risk assessment approach.
• Based on a described methodology for hazard intensity evaluation specific to each hazard type.

Limitations

• Last updated 2021-09-17 00:00:00; freshness should be verified.
• Row count and specific column definitions are unknown, limiting suitability assessment.
• Description metadata is limited; actual data quality and granularity require manual inspection after download.
