Planned projects can change or not go ahead; search the planning authority's applications by the reference shown for the plans, conditions and any objections. Construction brings traffic for some months; once built, solar farms and batteries are usually quiet, while turbines and waste plants can be seen or heard further away.
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
1 recorded flood covered the centre of this street's postcodes, most recently in February 1977 (Erewash th; main river).
| When | Flood | Source and cause |
|---|---|---|
| 25 Feb 1977 | Erewash th | Main river; channel capacity exceeded (no raised defences) |
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
2 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 91 times, for 305 hours in all, in 2025. They discharge into River Erewash.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Cromford Road - Cso No 3 Severn Trent Water | River Erewash | 63 | 243 | 180 m |
| Langley Mill - Station Road Cso Severn Trent Water | River Erewash | 28 | 62 | 580 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
This postcode is 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.
Radon
The postcode is in a 1 km square 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
4 historic landfill sites are within 500 m (0.3 miles) of the street's postcodes, the nearest 100 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| H. Poundall's Cromford Road, Langley Mill, Derbyshire | 1968 to 1990 | Inert, industrial, commercial | 100 m |
| Cornfield Meadows Off Cromford Road, Langley Mill | 1991 to 1993 | Inert, industrial | 100 m |

| Ex Gasholder Station North Street, Langley Mill | 1976 to 1987 | Inert, industrial | 430 m (0.3 miles) |
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 addresses are about 62 m above sea level.

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.

No collisions in which someone was hurt were reported on and around the street in 2021 to 2025.

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.
