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
Rivers, the sea or surface water: in this street's postcodes, 0 addresses are in areas at high risk, 0 at medium risk and 3 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 |
|---|---|---|---|
| LS25 7JP | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| LS25 7AA | not in 2 or 3 | 0 / 0 / 0 | unlikely |
| LS25 7JR | not in 2 or 3 | 0 / 0 / 3 | unlikely |
| LS25 7JT | 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
4 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 15 times, for 49 hours in all, in 2025. They discharge into Hollins Beck.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Kippax 80 Cso Yorkshire Water | Hollins Beck | 0 | 0 | 420 m (0.3 miles) |
| Westfield Lane Cso Yorkshire Water | Hollins Beck | 0 | 0 | 450 m (0.3 miles) |
| Kippax Storm Tanks Yorkshire Water | Hollins Beck | 3 | 19 | 570 m (0.4 miles) |
| Kippax Storm Tanks Yorkshire Water | Hollins Beck | 12 | 30 | 660 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
4 of the street's 4 postcodes are in a coalfield, in a low risk area: coal was mined in the area, but no workings shallow enough to matter for building are recorded.
Conveyancers usually still order a coal mining search (CON29M) for a home in a coalfield.
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 50 addresses are between 55 m and 72 m above sea level (69 m on average); the ground rises about 16 m from the lowest to the highest.

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.
