Flood risk
Rivers, the sea or surface water: in this street's postcodes, 10 addresses are in areas at high risk, 16 at medium risk and 17 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: of the 14 homes the Environment Agency counts, 0 are in areas at high risk, 2 medium, 5 low and 0 very low.
High: 3.3% (1 in 30) or more chance of flooding a year. Medium: 1% to 3.3%. Low: 0.1% to 1%. Very low: under 0.1%. The rivers and sea figures allow for flood defences. Counts cover whole postcodes, which can include other streets.
Flood zone for planning: at least one postcode centre is in flood zone 3. Zone 3 is a 1% (1 in 100) or greater annual chance of flooding from rivers, or 0.5% from the sea, ignoring defences.

What this page cannot tell you
- Whether a particular house is at risk of flooding, subsiding or anything else: the flood map is a model of areas and there is no property-level data here.
- What a home is worth now: sales are historic prices for the homes that happened to sell.
- How safe the street is: crime points are moved to anonymised locations and many crimes are never reported.
- Whether you would get a place at a school: distances are straight lines, not catchments.
- Who lives on the street now: census figures describe the small areas around it in March 2021, during a lockdown.
- How long a journey takes or how often anything runs: transport distances are straight lines to the nearest stops.
- Whether a GP practice is taking new patients, or a dentist new NHS patients.
- How loud a home is inside, or noise from industry, neighbours or smaller airfields: noise figures are models of road, rail and air traffic outside.
How each figure on this page is matched to the street and worked out: methodology.
