Flood risk
Rivers, the sea or surface water: in this street's postcodes, 1 address is in areas at high risk, 0 at medium risk and 1 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 |
|---|---|---|---|
| RH12 3SN | not in 2 or 3 | 0 / 0 / 1 | unlikely |
| RH12 3RQ | not in 2 or 3 | 1 / 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
1 storm overflow within 1 km (0.6 miles) of the street's postcodes spilled 29 times, for 276 hours in all, in 2025. They discharge into Boldings Brook, Trib of R.arun.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Warnham Wwps Southern Water | Boldings Brook, Trib of R.arun | 29 | 276 | 650 m (0.4 miles) |
A storm overflow lets sewage diluted with rainwater into a river, stream or the sea when heavy rain overwhelms the sewers, so the spills here affect the water they run into, not homes. A spill is counted the regulators' way: a first 12 hours, then each 24 hours it goes on.
Coal mining
No postcode centre on the street is in a coalfield: the Mining Remediation Authority records no coal mining risk here.
Radon
Every 1 km square the street's postcodes are in is in the lowest band of radon potential: fewer than 1 home in 100 is estimated to be at or above the Action Level. It is not a radon Affected Area.
Historic landfill
No historic landfill site is within 500 m (0.3 miles) of the street's postcodes.
Height above sea level
The street's 15 addresses are between 65 m and 90 m above sea level (76 m on average); the ground rises about 25 m from the lowest to the highest.

Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| Warnham CofE Primary School Church of England | Primary | 4–11 | 510 m (0.3 miles) | No published inspection | 48% at the expected standard in reading, writing and maths, 12% at the higher standard (2025; 69% in 2024 and 65% 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.

2 nurseries, pre-schools and clubs within 1.5 km (0.9 miles), the nearest 580 m (0.4 miles) from the middle of the street.

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.
