How should these values be interpreted?
How to read the landform
Delta / coastal lowland is a broad terrain classification. Use it as context for drainage and ground conditions, not as a property-level safety determination.
How to read elevation
The elevation range within 250 m is about 1.3 m. Absolute elevation alone does not determine flood risk; compare the property with nearby roads and mapped inundation.
How to read ground values
AVS30 (163 m/s) indicates average ground stiffness to 30 m depth. The amplification factor (2.14) compares shaking tendency; neither determines a building's seismic performance or need for ground improvement.
How to read hazards
At the station representative point, mapped flood status is inside and landslide-warning status is outside. Verify the exact property on official maps because conditions vary within the 1.5 km area.
These values describe the Iwane Station representative point, not every property in the station area. Check official hazard maps, disclosure documents and plot-specific ground investigations before purchase.
