The TW10 postcode district covers Ham, Petersham & Richmond Riverside, close to Teddington, Trowlock Island, Twickenham, and surrounding villages in parts of England and Surrey.

119 postcodes in the TW10 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 5 high, 1 medium, 100 low, 13 very low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
