Flood Risk Analysis

Tacoma, 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.

Some properties are located in areas prone to flash flooding.

Tacoma 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.

Tacoma sits within ClimateNest's suburb-level hazard model for flood risk. 7.9% of the suburb's land area is mapped in high-risk flood zones and 74% 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 Tacoma.

Tacoma (postcode 2259) 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 surface flood (13.1% of land in high-risk zones), bushfire (11.4% of land in high-risk zones), riverine flood (7.9% of land in high-risk zones). Exposure is not uniform across Tacoma โ€” 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 Tacoma at risk of flooding?

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

What flood insurance costs can I expect in Tacoma?

Insurance costs for flood cover in Tacoma 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 Tacoma?

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

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

ClimateNest's hazard overlay maps 13.1% of Tacoma in high-risk zones for surface flood, with a further 78.8% in moderate-risk zones. Suburb-level exposure is not uniform โ€” individual properties can differ from these averages, so an address-level check is recommended.
