Flood Risk Assessment in Kendal

A flood risk assessment in Kendal has to start with the rivers that meet above the town. The Sprint joins the River Kent below Burneside, the Mint comes in at Mintsfeet, and Stock Beck runs through Sandylands in culverts, and Blind Beck and Natland Beck drain the south and west of the town. When Storm Desmond broke on 5 December 2015, about 2,150 Kendal properties flooded. We prepare flood risk assessments in Kendal for planning, house purchase, mortgage and insurance, along with sequential and exception tests and surface water drainage strategies.

On this page Kendal means the town's built-up area: the centre from Stricklandgate to Highgate and Kirkland, Mintsfeet and Sandylands on the north-east side, Hallgarth to the north, Heron Hill and the hospital to the south, and the LA9 postcode district that covers it. Burneside, Natland and Oxenholme are separate villages just outside the outline. Westmorland and Furness Council decides planning applications across the whole of it; the Lake District National Park boundary runs close to the town's western edge but takes in none of the built-up area.

In 2015 the Kent at Victoria Bridge peaked at 403 cubic metres a second. The channel built through the town in the 1970s is usually quoted as designed for about 280.

Five watercourses through one valley: where Kendal floods from

River flooding drives most of Kendal's risk, but not from one river. Above Victoria Bridge the Kent drains a mostly rural catchment of 183 square kilometres, part of it in the Lake District, and the town sits just below two big confluences. Smaller becks run through Sandylands, Kirkland and the south of the town, much of their length underground. The Kent responds fast to rain on the fells, while Stock Beck floods when its culverts fill, so the beck beside a site matters as much as its distance from the river.

The Kent, Mint and Sprint can all be watched on our live river levels map, and the Environment Agency publishes the River Kent level at Victoria Bridge every 15 minutes. Whether the beck beside a site is a main river or an ordinary watercourse decides who you talk to about it, which our guide to main rivers and ordinary watercourses explains; for the culverted becks, our note on culverts and consent sets out who owns what.

Check a postcode anywhere from Hallgarth to Natland Road

Enter a postcode below and the tool works as a Kendal flood map for that spot, with Environment Agency data for rivers, surface water and reservoirs; our full flood risk map covers the rest of England. The coral line follows the ONS built-up area for Kendal, from Hallgarth and Mintsfeet in the north to the hospital and Natland Road in the south. In the valley bottom the river layer matters most; on the slopes of Kendal Fell and in Sandylands, check the surface water layer too. Our guide to flood zones 1, 2 and 3 explains how the layers differ.

Kendal's flood record, from 1954 to Storm Desmond

The Environment Agency's investigation of the 2015 flood traces flooding in Kendal back to the 17th century and lists the modern events below. The pattern matters for any site: defences were built after each big flood, and each later flood found the next weak point.

1. December 1954. The worst flood since November 1898 reached about 300 homes and 70 commercial properties. After further floods in 1964 and 1968, the River Kent channel through the town was widened and deepened, work finished in 1979.
2. December 1985. A flood of similar size passed through the widened channel without serious damage to the protected area, but Mintsfeet flooded, and the earth embankments there followed.
3. February 2004. Eighty properties flooded in the centre and at Mintsfeet, including 20 premises on the Lake District Business Park and 27 on the Mintsfeet Industrial Estate, with homes on Busher Walk, Garden Road and Burneside Road.
4. 6 to 7 January 2005. More than 100 properties flooded. The Kent stood about 200 mm higher than in 2004; Mintsfeet lost 20 homes and 40 commercial premises, and Busher Walk, Aynam Road and Aikrigg End were among the worst hit.
5. November 2009. In the storm that devastated Cockermouth, four properties at Benson Green flooded from the Kent, and basements on Aynam Road and Lound Street filled with groundwater and drainage water.
6. 28 June 2012. A cloudburst, 20 mm in a quarter of an hour at the nearest gauge, flooded nine commercial properties on Highgate and Kirkland and nine homes on the Hallgarth estate, with no river involved.
7. 5 to 6 December 2015. Storm Desmond flooded about 2,150 properties, mostly in Mintsfeet and Sandylands. River, culvert, surface water and groundwater flooding all played a part across the town.

Those figures come from the Kendal flood investigation report the Environment Agency prepared with the county council in 2016, and the two 2012 reports are on the council's list of Section 19 investigations. The Flood Hub's later count of 2,276 properties and businesses covers Burneside, Staveley and Ings as well as the town.

Rain, sewers and groundwater: flooding away from the Kent

Some of Kendal's flooding never comes near the river. The county's preliminary assessment ranks Kendal as the biggest surface water cluster in Westmorland and Furness, with about 1,973 people at risk in a 1 in 200 rainfall event, and the 2015 report found water rising through floors before the Kent overtopped. A site on Flood Zone 1 high ground can still flood from these sources.

• Steep streets into Highgate. In June 2012 roads dropping off Kendal Fell funnelled water onto the A6, which became impassable; the county's report found the rain exceeded what the highway drains and public sewers were built to carry.
• Hallgarth's springs. On the Hallgarth estate United Utilities found groundwater seeping into the sewers through the joints and a high water table, so the system surcharged in heavy rain and foul water reached homes on Low Garth.
• The worst postcode for sewer flooding. Of all the postcode sectors in the council's 2026 flood study, LA9 6 in Kendal has the most reported sewer flooding incidents over ten years (150 to 250); LA9 5 in west Kendal records 51 to 75.
• Stock Beck ponding. The council's detailed Kendal surface water model, built with United Utilities' sewer network, shows deeper and wider flooding in the Stock Beck catchment than the national map, especially in Sandylands, with ponding east of the Lakes Line at Jewsons Yard and Kendal Cricket Club.
• Water through the floor. In 2015 residents of 17 properties around Ann Street and Castle Street reported groundwater coming up first, Aynam Road basements flooded before the river did, and in Sandylands water rose through floors from the alluvium and sandstone beneath.

That is why a Kendal assessment looks at the drainage route and the ground as well as the flood zone. Our notes on sewer flooding and on groundwater in planning applications cover the evidence a council expects, and basement plans near Aynam Road face the rules in our guide to basement conversions in a flood zone.

What the 2026 flood study says about building in Kendal

Westmorland and Furness Council's Level 1 Strategic Flood Risk Assessment, prepared by AECOM and issued in final form on 20 April 2026, picks Kendal as one of four towns for closer analysis. It is the evidence base for the new Local Plan and the reference an officer will check a Kendal application against. Five of its findings bear directly on a planning application.

• Functional floodplain by the retail park. Flood Zone 3b is mostly confined to the Kent's channel, but there are significant areas near South Lakeland Retail Park in the north of the town and small areas on both banks through the centre. The Calder Drive storage area on Stock Beck counts as functional floodplain too.
• Defended and undefended maps differ. With defences in place the 1% annual chance flood stays largely in channel. Without them it spreads through the centre and towards the retail park, and with climate change added the undefended extent grows most on the east bank through the middle of town.
• Dry islands. Kendal is named among the places where higher ground can be cut off by surrounding floodwater, so a site above the flood outline may still lack a dry way out.
• Reservoirs upstream. A breach at Kentmere Head, Borrans, Dubbs, Gurnal Dubs or Little Borwick Fold would reach Kendal in the study's mapping. All are regulated under the Reservoirs Act 1975 and the residual risk is low.
• Infiltration is patchy. Ground highly compatible with soakaways is limited, though parts of south-west Kendal score well; elsewhere a site has to prove infiltration works before relying on it.

The study and its maps are on the council's evidence base page, with the Level 1 SFRA report as a PDF. Our guide to the functional floodplain explains why Flood Zone 3b near the retail park rules out most kinds of building, and our note on reservoir flooding covers how a breach map is used.

Is a site behind Kendal's new defences still in Flood Zone 3?

Usually, yes. The Environment Agency's Kendal Flood Risk Management Scheme is raising walls and banks through the town, but the Flood Map for Planning is drawn as if defences were absent. A site behind a new wall on Aynam Road or at Mintsfeet stays in Flood Zone 3 for planning, and its assessment has to deal with what happens if the defences are overtopped or fail.

• What is being built. About 6 km of walls, embankments and glass panels from Mintsfeet to Helsington Mills, more than half set back from the river, with flood gates where paths cross. Construction started on 15 February 2021.
• Stock Beck pumps. A new pumping station at Gooseholme takes over when the Kent is too high for Stock Beck to drain. In April 2026 its control building was structurally complete and electrical commissioning was due before the summer.
• When it finishes. The Flood Hub's scheme page says the Kendal works will be complete in 2027; the council's 2026 flood study says the first phase is due in 2028. The Environment Agency will update the flood modelling after each phase.
• What comes next. The catchment scheme aims at a 1 in 100 standard of protection, using about three million cubic metres of upstream storage and a drain to carry Stock Beck's excess into the Mint, away from Sandylands. Kendal's allocation for 2026 to 2027 was £24.3 million.

The scheme's progress is published on The Flood Hub and the council's scheme page, its upstream plans on the Flood Hub's upstream measures page, and the funding in the Environment Agency's March 2026 announcement. Our articles on why a site stays in a flood zone after new defences, on residual flood risk and on glass-panelled flood walls, which looks at Aynam Road, go further.

Policies DM6 and CS8.8: the tests a Kendal scheme has to pass

Kendal applications are still decided under the South Lakeland Local Plan, which Westmorland and Furness Council kept in force after reorganisation until its own plan replaces it. Two policies carry the flood tests: CS8.8 in the 2010 Core Strategy and DM6 in the 2019 Development Management Policies. Above them sits chapter 18 of the August 2026 NPPF.

• Flood Zone 1 first (CS8.8). Most new development should be in Flood Zone 1. In Zones 2, 3a and 3b a scheme has to be compatible with national policy and pass the sequential test, and the exception test where it applies, without significantly reducing the floodplain's capacity to store water.
• Risky land is kept for water (DM6). Land shown at risk of river, sea or surface water flooding is treated as land needed for current and future flood management. Building there is avoided unless the use is compatible with flooding or compensatory storage is provided.
• An assessment and a drainage strategy (DM6). The policy says "An appropriate Flood Risk Assessment and Drainage Strategy should be provided with applications", following national guidance and the Cumbria Development Design Guide.
• The drainage order (DM6). Surface water goes to the ground first, then a watercourse, then a surface water sewer, and a combined sewer only as a last resort, limited to an attenuated greenfield rate with allowances for climate change and urban creep.
• Allocations with conditions. The 2013 Land Allocations plan asks Kendal sites to avoid flood risk around the Kent and north of the town. It required on-site attenuation at West of High Sparrowmire, a flood risk assessment for Eskdale House on Shap Road, and a full study of Stock Beck and an undersized culvert at East of Castle Green Road.

National policy F4 sets when an assessment is needed, F5 and F6 the sequential and exception tests, and F8 expects every development to follow the 2025 national standards for sustainable drainage; our summary of the August 2026 NPPF changes covers each. The plan documents are on the council's South Lakeland Local Plan page, with DM6 and CS8.8 in the adopted PDFs and the site requirements in the Land Allocations plan.

The council is also the Lead Local Flood Authority, consulted on major schemes' surface water drainage and responsible for ordinary watercourses and groundwater. It offers pre-application drainage advice for five or more homes or commercial schemes, and its flood risk management strategy sets the local priorities. Work on a new Westmorland and Furness Local Plan to 2045 began formally in June 2026. Our guide to the role of the LLFA and our note on how reorganisation changed flood planning explain the split.

Which schemes trigger a flood risk assessment in Kendal?

In Kendal the answer turns on the flood zone, the size of the site and what the local evidence shows beyond the zone. The table sets out the common cases; the address and the plans settle any particular one. If you are unsure, the quickest route is to send them to us.

Our step-by-step note on how a flood risk assessment is done shows what goes into each kind, and the climate change allowances the Kent's peak flows are raised by are set out separately.

What Kendal sites need from our consultants, and why

The reports below come up again and again on Kendal sites, for developers, architects, home owners, buyers and businesses. A flood risk assessment asks whether the site is safe, the sequential and exception tests ask whether it should be built there at all, and a drainage strategy shows where the water goes.

• Every source on the site. In a town where the Kent, the culverted becks, the sewers and the groundwater all flooded property in 2015, a flood risk assessment has to weigh each of them for the site in hand.
• For a planning application. From a Mintsfeet industrial unit to a flat above a Highgate shop, a flood risk assessment for planning gives Westmorland and Furness Council the evidence DM6 and CS8.8 ask for.
• Before you buy. With about 2,150 properties flooded in 2015 and more than 100 in 2005, a flood risk survey for property purchase checks a Kendal home's history and exposure before exchange.
• Whether the site should be there. New homes in Flood Zone 2 or 3 along the Kent or Mint need a sequential and exception test before CS8.8 lets them proceed.
• Drainage the council will accept. Westmorland and Furness Council expects a drainage strategy alongside the assessment under DM6, and consults its flood team on major schemes.
• Surface water on the site. With Stock Beck ponding in Sandylands and LA9 6 the worst postcode for sewer flooding, a surface water drainage strategy has to follow the DM6 drainage order and prove any soakaway works.
• Clearing conditions. Kendal permissions often carry drainage conditions on attenuation and maintenance, and the discharge of drainage conditions turns the approved strategy into detail the council can sign off.
• Levels from the model. With the Kent's 2015 peak far above the 1970s channel and the Environment Agency model being updated as the scheme is built, flood modelling can be needed to set design levels for a riverside site.
• Water from below. Groundwater came through floors in Sandylands and Ann Street in 2015 and into Aynam Road basements in 2009, so a groundwater flood risk assessment belongs in many Kendal reports.
• A plan for getting out. With ten Environment Agency warning areas in the town and dry islands noted in the 2026 study, a flood warning and evacuation plan is often part of a riverside scheme.
• For insurers. Busher Walk flooded in 2004, 2005 and 2015 and Mintsfeet homes in 2005 and 2015, and an insurance flood risk assessment gives the insurer property-level evidence.
• Employment land. The council counts five strategically important business sites in Kendal, and a commercial scheme seeking certification can use a BREEAM flood risk assessment for the credit.
• Keeping a business running. Forty-seven business park and industrial estate premises flooded at Mintsfeet in 2004 alone, so business continuity planning helps firms on the valley floor plan for the next one.
• Buying commercial property. Industrial units at Mintsfeet, on the business parks and around Appleby Road sit in Kent and Stock Beck warning areas, and commercial due diligence puts that on the record before a deal.
• Foul water capacity. Allocated sites such as West of High Sparrowmire carried sewer capacity warnings, so larger schemes may need a foul drainage strategy agreed with United Utilities.

Kendal's flood contacts, from Victoria Bridge to the sewers

Responsibility in Kendal is split by source. The Environment Agency covers the main rivers and warnings, the council covers surface water, groundwater and ordinary watercourses, United Utilities the public sewers, and the emergency services anyone in danger.

There is no internal drainage board in Cumbria. For the county picture see our page on flood risk assessment in Cumbria; further afield we cover Carlisle on the Eden, Cockermouth on the Cocker and Derwent, and Lancashire to the south.
