Flood risk
Rivers, the sea or surface water: in this street's postcodes, 1 address is in areas at high risk, 2 at medium risk and 2 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.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| BH23 7EF | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| BH23 7DX | not in 2 or 3 | 0 / 0 / 0 | unlikely |

Recorded floods
No recorded flood covers the centre of any of this street's postcodes.
Recorded floods are where floodwater was seen or surveyed after a flood. Many floods were never mapped, an outline over a postcode's centre does not mean every home in it flooded, and homes outside one may have. Ask the seller whether the home itself has flooded.
Coastal erosion
No projected coastal erosion zone is within 1 km (0.6 miles) of the street's postcodes.
Storm overflows
No storm overflow outlet is within 1 km (0.6 miles) of the street's postcodes.
Coal mining
No postcode centre on the street is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
The highest radon potential in the 1 km squares around the street's postcodes is 3 to 5%: up to that share of homes there is estimated to be at or above the Action Level of 200 becquerels per cubic metre. At least part of that area is a radon Affected Area, where 1% or more of homes are.
By postcode centre: less than 1% (8); 3 to 5% (2).
Radon is a natural radioactive gas from the ground that can build up indoors; long exposure raises the risk of lung cancer. A three-month test with two small detectors is the only way to know a home's level, and a high level can usually be brought down with a sump or better ventilation. Homes built here in recent decades should have radon protection under the building regulations (basic protection from 3%, full protection from 10%). UKHSA sells a radon report for a single address from its detailed map at ukradon.org.
Historic landfill
1 historic landfill site is within 500 m (0.3 miles) of the street's postcodes, the nearest 190 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| Roeshot Pit Hinton Admiral, New Milton, Hampshire | Not recorded | Inert; gas control on site | 190 m |
Closed tips can give off gas (methane and carbon dioxide) and leak into the ground for years. An environmental search, which conveyancers usually order, looks at landfill and contaminated land around the home; the council keeps a register of land it has found to be contaminated.
Height above sea level
The street's 62 addresses are between 9 m and 58 m above sea level (42 m on average); the ground rises about 49 m from the lowest to the highest.

Traffic on nearby roads
The busiest counted road within 500 m (0.3 miles) is the A35 between A337 and LA Boundary, with 22,252 motor vehicles a day on average in 2025, 400 m (0.2 miles) from the street's postcodes.
| Road | Between | Vehicles a day | Lorries | Ten years before | Distance |

| Minor road | Not recorded | 1,336 counted 2025 | 0% | 420 m (0.3 miles) |
Each figure is the annual average daily flow: the motor vehicles passing the count point, both ways, on an average day of the year. A point is counted by hand on a weekday every few years and estimated from the trend on similar roads in between. Lorries are heavy goods vehicles, as a share of all motor vehicles.

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; road collisions count only those in which someone was hurt and the police were told.
- 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.
