What is the flood risk in DT6 4HE?

Flood risk at DT6 4HE is rated High, based on Environment Agency NaFRA2 modelling.

Environment Agency flood zone data places DT6 4HE in the high flood risk band. EA NaFRA2 data shows 10 at high risk, 3 at low risk in this postcode. The band reflects the highest flood risk within the postcode; some properties within this postcode may face little or no direct flood risk. A formal flood risk search and review of buildings insurance availability is recommended before any property transaction in this area.

How is the air quality in DT6 4HE?

Air quality at DT6 4HE is rated Low, based on Defra UK-AIR annual mean PM2.5 data. Fine particulate matter (PM2.5) comes primarily from road traffic, industry, and domestic burning. Long-term exposure above the WHO guideline of 5 µg/m³ is linked to respiratory and cardiovascular health risks. Buyers and renters in higher air quality risk areas may wish to consider whether the property is near busy roads or industrial sources.

Is subsidence a risk at DT6 4HE?

British Geological Survey data classes the underlying soil at DT6 4HE as Riverine Clay And Floodplain Sands And Gravel, with shrink-swell hazard rated improbable (subsidence risk band: Low). A structural survey is the reliable way to assess ground conditions for a specific property.

Is DT6 4HE at risk of coastal erosion?

The nearest projected coastal erosion zone to DT6 4HE is 128 m away (Erosion projected by 2055 (no climate change uplift) - SMP policy: Hold The Line mapping) and the postcode is in the very high coastal erosion risk band. Coastal erosion risk varies along the shoreline depending on local geology, sea defences and Shoreline Management Plan policy. Check the Shoreline Management Plan for this stretch for the projections that apply to a specific property.

Where does this data come from?

This LocalRisk report for DT6 4HE draws on four official UK open data sources: Environment Agency NaFRA2 flood modelling, Met Office UKCP18 climate projections, Defra UK-AIR PM2.5 monitoring, and British Geological Survey GeoClimate subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Dorset and is updated as new official datasets are published.

About the Dorset area

Dorset has a mixed coastal and rural setting with chalk downland, river valleys and low-lying plains and experiences cool, wet winters and warm summers, shaped by maritime influence and varied topography.

What should buyers and renters check in DT6 4HE?

Practical check: EA flags 13 properties at flood risk here, near the coast - compare the floor level to the highest recorded tide line and check for flood resilience measures. With 23 hot days projected (UKCP18 50th percentile, 2021-2040 average under RCP8.5), note which bedrooms face west (hottest in evening) and whether windows allow through-ventilation. The nearest projected erosion zone is 128m away - check the Shoreline Management Plan policy for this stretch and whether the property is within 100 years of the erosion line. These are postcode-level indicators - conditions vary between individual properties.
