Flood Risk Analysis

Stony Crossing, located in New South Wales, has a notable flood risk profile based on available data including proximity to waterways, elevation, and historical flood events. The Bureau of Meteorology (BOM) maintains river height and flood warning data for catchments across New South Wales.

Historical flood data indicates inundation in low-lying areas during heavy rainfall events.

Stony Crossing faces a moderate risk of flooding due to its proximity to waterways and low-lying areas. Climate change is expected to increase rainfall intensity, exacerbating flood risk.

For a comprehensive property-specific flood assessment including address-level elevation data, flood overlay mapping, and insurance cost estimates, use the ClimateNest full analysis tool. General suburb data cannot replace a site-specific evaluation.

Stony Crossing sits within ClimateNest's suburb-level hazard model for flood risk. 8.2% of the suburb's land area is mapped in high-risk flood zones and 79.5% in moderate-risk zones, based on the national hazard overlay. Exposure at this scale varies street by street, which is why an address-level check matters before you buy or insure a specific property in Stony Crossing.

Stony Crossing (postcode 2734) is tracked in ClimateNest's suburb hazard model, which maps the share of the suburb's land exposed to each hazard at high and moderate levels. The suburb's highest high-risk exposures are bushfire (11.8% of land in high-risk zones), riverine flood (8.2% of land in high-risk zones), surface flood (6.9% of land in high-risk zones). Exposure is not uniform across Stony Crossing — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.
