Does SL2 flood?

Yes — parts of the SL2 district carry real flood risk: 46 of its 96 at-risk postcodes reach the Environment Agency's High likelihood band. The SL2 postcode district covers Upton Lea, Wexham Court, Manor Park & Stoke, Farnhams & Stoke Poges, close to Eton, Datchet, Windsor, and surrounding villages in parts of England and Windsor and Maidenhead.

96 postcodes in the SL2 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 46 high, 9 medium, 41 low. A postcode not listed here has no properties in any recorded risk band (which is good news, but never proof it cannot flood).
