Does DN20 flood?

Yes — parts of the DN20 district carry real flood risk: 36 of its 102 at-risk postcodes reach the Environment Agency's High likelihood band. The DN20 postcode district covers Broughton & Scawby, Ridge, close to Brigg, Brandy Wharf, Scotter, and surrounding villages in parts of Lincolnshire and North Lincolnshire.

102 postcodes in the DN20 district appear in the Environment Agency's rivers-and-sea flood-risk dataset — worst bands: 36 high, 15 medium, 37 low, 14 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).
