Does DT8 flood?

Yes — parts of the DT8 district carry real flood risk: 10 of its 54 at-risk postcodes reach the Environment Agency's High likelihood band. The DT8 postcode district covers Beaminster, Marshwood Vale, Eggardon, Yetminster, close to Netherbury, Hooke, Powerstock, and surrounding villages in parts of Dorset and Somerset.

54 postcodes in the DT8 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 10 high, 18 medium, 26 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
