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, 2 addresses are in areas at high risk, 1 at medium risk and 17 at low risk. Each address counts once, at the higher of its rivers-and-sea and surface-water risk.
Rivers and the sea alone: of the 19 homes the Environment Agency counts, 1 are in areas at high risk, 0 medium, 13 low and 0 very low.
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: at least one postcode centre is in flood zone 3. Zone 3 is a 1% (1 in 100) or greater annual chance of flooding from rivers, or 0.5% from the sea, ignoring defences.
| Postcode | Planning zone | Addresses at high / medium / low risk | Groundwater |
|---|---|---|---|
| CA12 5LE | not in 2 or 3 | 0 / 0 / 2 | unlikely |
| CA12 5EW | zone 2 | 0 / 0 / 0 | unlikely |
| CA12 5LG | zone 3 | 2 / 1 / 3 | unlikely |
| CA12 5LL | zone 3 | 0 / 0 / 12 | unlikely |
Recorded floods
5 recorded floods covered 3 of the centres of this street's postcodes, most recently in December 2015 (Keswick; main river).
| When | Flood | Source and cause | Postcodes |
|---|---|---|---|
| 5 Dec 2015 | Keswick | Main river; overtopping of defences | CA12 5EW, CA12 5LG, CA12 5LL |
| 19 Nov 2009 | Keswick | Main river; overtopping of defences | CA12 5EW |
| 7 Jan 2005 | Keswick | Main river; overtopping of defences | CA12 5EW |
| 21 Dec 1985 | Not named | Not recorded | CA12 5LG, CA12 5LL |
| 31 Oct 1977 | Keswick | Main river; channel capacity exceeded (no raised defences) | CA12 5EW |
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
3 storm overflows within 1 km (0.6 miles) of the street's postcodes spilled 55 times, for 63 hours in all, in 2025. They discharge into The River Greta, River Greta.
| Overflow | Into | Spills | Hours | Distance |
|---|---|---|---|---|
| Rawnsley Hall Pumping Station United Utilities | The River Greta | 54 | 63 | 420 m (0.3 miles) |
| Penrith Rd United Utilities | River Greta | 0 | 0 | 520 m (0.3 miles) |
| Lattings Close Cso 028Nf United Utilities | River Greta | 1 | 0 | 900 m (0.6 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
1 historic landfill site is within 500 m (0.3 miles) of the street's postcodes, the nearest 120 m away.
| Site | Waste went in | Waste | Distance |
|---|---|---|---|
| Town Cass Keswick, Cumbria | 1972 to 1986 | Inert, industrial, commercial, household, liquid sludge | 120 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 25 addresses are between 77 m and 84 m above sea level (83 m on average); the ground rises about 7 m from the lowest to the highest.

Climate, daylight and earthquakes
Monthly temperatures and rainfall, sunrise and sunset through the year, and earthquakes recorded nearby since 1970 are much the same across the area, so they are worked out once for Cumberland: see them on the Cumberland page.
Nearest schools
| School | Phase | Ages | Distance | Inspection | Exam results |
|---|---|---|---|---|---|
| St Herbert's CofE (VA) Primary and Nursery School Church of England | Primary | 3–11 | 840 m (0.5 miles) | Good (Feb 2024, overall grade under the previous framework) | 54% at the expected standard in reading, writing and maths, 8% at the higher standard (2025; 57% in 2024 and 48% in 2023) |
| Keswick School | Secondary | 11–18 | 910 m (0.6 miles) | Outstanding (Apr 2024, overall grade under the previous framework) | GCSE 2026 (provisional): Attainment 8 50.9 (52.1 in 2025 and 54.1 in 2024); 54.7% grade 5+ in English and maths A level 2025: average grade C+; 16.7% AAB or better; progress average |
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.
Nurseries and childcare
No nursery, pre-school or out-of-school club on Ofsted's register is within 1.5 km (0.9 miles) of the middle of the street.
Ofsted also registers 57 childminders and 3 home childcarers (nannies) in Cumberland. It does not publish their addresses, so they cannot be shown here; the council's family information service lists those taking children.

The busiest counted road within 500 m (0.3 miles) is the A5271 between B5289 and A591, with 8,065 motor vehicles a day on average in 2025, 300 m 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.
