Flood Risk Analysis

Stonehenge, 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.

Local drainage infrastructure may be insufficient to handle increased rainfall intensity.

Stonehenge faces a moderate risk of flooding, primarily from heavy rainfall events and potential riverine flooding. Local topography and drainage capacity influence the extent of potential inundation.

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.

Stonehenge sits within ClimateNest's suburb-level hazard model for flood risk. 8.7% of the suburb's land area is mapped in high-risk flood zones and 76.6% 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 Stonehenge.

Stonehenge (postcode 2370) 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 riverine flood (8.7% of land in high-risk zones), bushfire (8.7% of land in high-risk zones), surface flood (5.8% of land in high-risk zones). Exposure is not uniform across Stonehenge — individual properties can sit well above or below these averages, so an address-level check is recommended before buying, selling or insuring.

Frequently Asked Questions

Is Stonehenge at risk of flooding?

Based on available data, Stonehenge has a notable flood risk profile. Flood risk varies by address — check your specific property for precise flood zone mapping and elevation data with ClimateNest.

What flood insurance costs can I expect in Stonehenge?

Insurance costs for flood cover in Stonehenge depend on the property's flood zone classification, elevation, and proximity to waterways. ClimateNest provides address-level insurance cost estimates based on your property's specific hazard exposure.

Does flood risk affect property values in Stonehenge?

Yes, flood risk can affect property values in Stonehenge. Properties in mapped flood zones may experience lower buyer demand, reduced valuations, and higher insurance costs. Lenders increasingly assess flood exposure as part of mortgage risk evaluation.

How does elevation affect flood risk in Stonehenge?

Elevation is a critical factor in flood risk. Properties at higher elevations within Stonehenge typically have lower flood exposure than those near waterways or in low-lying areas. Address-level elevation data combined with BOM flood mapping provides the most accurate picture.

What share of Stonehenge is exposed to high riverine flood risk?

ClimateNest's hazard overlay maps 8.7% of Stonehenge in high-risk zones for riverine flood, with a further 76.6% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
