Emergency works are often permitted after they begin.

Flood risk

Rivers, the sea or surface water: in this street's postcodes, 10 addresses are in areas at high risk, 12 at medium risk and 27 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.

Rivers and the sea alone: no home is in an area at risk.

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: no postcode centre on this street is in flood zone 2 or 3.

Height above sea level

The street's 99 addresses are between 8 m and 11 m above sea level (9 m on average).

Source: Ordnance Survey, OS Terrain 50, July 2026: the height of the ground on a 50 m grid, read at each address, in metres above Ordnance Datum (mean sea level at Newlyn). It is the lie of the land, not floor or threshold levels, and is accurate to a few metres. Being low-lying is not in itself a flood risk; the flood section above says what the flood maps show.

Air quality

Source: Defra, modelled background air pollution, annual means for 2024, for the 1 km square that holds the middle of the street. These are background levels, away from the kerb: beside a busy road nitrogen dioxide in particular can be several times higher. UK limits are the legal annual limits for England and Wales; the World Health Organization's 2021 guidelines are much stricter, and most towns and cities are above them.

Annual means in µg/m³ (micrograms per cubic metre of air)
PollutantHereUK limitWHO guideline
Nitrogen dioxide (NO2)10.34010
Fine particles (PM2.5)7.3205
Particles (PM10)12.04015

All three are within the UK legal limits; nitrogen dioxide and PM2.5 are above the WHO guideline, as in most towns and cities.

Road and rail noise

Source: Defra, strategic noise mapping Round 4 (England), modelled for 2021 and published in December 2023, and its airport maps of the same round for the fifteen largest English airports, published in April 2026: Lden, the average sound level over a whole day with extra weight for the evening and night, on a 10 m grid, read at each address. These are models of traffic, not measurements; they leave out smaller airports and airfields, industry and neighbours, and a room at the back of a house is often much quieter than the front. The World Health Organization's guidelines are 53 dB for road traffic, 54 dB for railways and 45 dB for aircraft (below the lowest level shown here).

People and work

Source: ONS Census 2021, taken on 21 March 2021, for the 2 Output Areas (small census areas of about 125 households each) that this street's postcodes are in: 3,066 residents in 153 households. The census was taken during a lockdown, so working from home is high and travel to work low compared with now. ONS swaps a few records between neighbouring areas and adds small amounts of noise to counts to protect privacy, so small differences mean little. Industry is not published for areas this small.

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.
