Roadworks
No street works under way, planned or finished in the last three months on this street, in permits up to 31 October 2026.
Flood risk
No address in this street's postcodes is in an area at high, medium or low risk of flooding from rivers, the sea or surface water. The rest are in areas at very low risk: less than a 0.1% (1 in 1,000) chance a year.
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 is in flood zone 2 or 3.
Recorded floods
No recorded flood covers the centre 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 here is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
The postcode is in a 1 km square with radon potential up to 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 the square is a radon Affected Area, where 1% or more of homes are.
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 320 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| Pit North of A27 Boxgrove, Sussex | 1985 | Inert | 320 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 16 addresses are between 22 m and 25 m above sea level (24 m on average).

Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| Tangmere Primary Academy | Primary | 3–11 | 80 m | No published inspection | 70% at the expected standard in reading, writing and maths, 0% at the higher standard (2025; 60% in 2024 and 78% in 2023) |
| Boxgrove CofE Primary School Church of England | Primary | 4–11 | 670 m (0.4 miles) | Good (Jun 2023, overall grade under the previous framework) | 15% at the expected standard in reading, writing and maths, 0% at the higher standard (2025; 36% in 2024 and 30% in 2023) |
Exam results are from the Department for Education's school performance tables (Explore Education Statistics, Open Government Licence), for all pupils at each school. The middle school in England had 63% at the expected standard at the end of primary school (2025), Attainment 8 of 46.0 at GCSE (2026) and an A level average of C+ (2025). Attainment 8 adds up a pupil's grades in eight GCSEs, with English and maths counted twice (90 is the most), averaged over the school's pupils. Progress 8 compares pupils with others who had the same results at the end of primary school; it is not published for GCSEs in 2025 and 2026, as those pupils sat no primary tests during the pandemic. Small year groups swing from year to year, and figures for very small ones are withheld.

Traffic on nearby roads
The busiest counted road within 500 m (0.3 miles) is the A27 between A285 and A29, with 49,129 motor vehicles a day on average in 2025, 410 m (0.3 miles) from the street's postcodes.

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.
