Flood Risk Analysis

Texas, 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 that Texas has experienced several significant flood events in the past.

Texas is located near the Dumaresq River and is susceptible to flooding during periods of heavy rainfall. Climate change is expected to increase the intensity of rainfall events, potentially leading to more frequent and severe flooding.

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.

Texas sits within ClimateNest's suburb-level hazard model for flood risk. 5.1% of the suburb's land area is mapped in high-risk flood zones and 70.7% 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 Texas.

Texas (postcode 4385) 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 (19.3% of land in high-risk zones), surface flood (9.4% of land in high-risk zones), extreme wind (5.7% of land in high-risk zones). Exposure is not uniform across Texas — 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 Texas at risk of flooding?

Based on available data, Texas 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 Texas?

Insurance costs for flood cover in Texas 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 Texas?

Yes, flood risk can affect property values in Texas. 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 Texas?

Elevation is a critical factor in flood risk. Properties at higher elevations within Texas 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 Texas is exposed to high bushfire risk?

ClimateNest's hazard overlay maps 19.3% of Texas in high-risk zones for bushfire, with a further 54.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
