Here are the 14 areas of Northampton which have been identified as most at risk of surface water flooding.
The at-risk areas are listed on Get The Data and are identified by postcode, showing the level of risk, suitability and if the flooding poses a risk to insurance. The data is taken using a single point within each postcode using Open Postcode Geo, identifying the flood risk area which that point falls within. There may be other points, within the postcode which fall into a different area, and hence have a different risk level.
