Flood resilience

In the event of a surface water flooding incident, it is generally recognised that by the time sand bags are brought to site, flood water will have already the entered property. Occupiers (especially those in basements) and businesses that are aware of a local surface water flooding risk are to be encouraged to have flood protection and perhaps sandbags to hand and know how to deploy them.

The London Borough of Camden does not stock or source sandbags for supply to the public.

Thames Water does not supply sandbags.

 

Report flooding

Who to contact in the event of a flood

A number of different agencies have responsibility for responding to flooding depending on the location.

After a flood

If you have been flooded internally please email greencamden@camden.gov.uk  and we will get in contact with you. This should not be used in an emergency to request Council assistance. 

The London Borough of Camden as a Lead Local Flood Authority is required to undertake investigations on significant flood events under the Flood and Water Management Act and the Flood Risk Regulations. The criteria triggering a Flood Investigation is set out in the Council’s Flood Risk Management Strategy. 

By reporting flooding to the Council after the event, it will help us collate a full picture on what and where issues happened. The focus and the priority for the Council will be on significant reports of flooding that have resulted in internal flooding of properties or commercial premises, though all reports are useful. 

All the information supplied will form part of a historic database of flooding for the London Borough of Camden. The Council will retain this information and may wish to use this and photos provided within the Flood Investigation. Your personal details will not be published though this data will be retained in perpetuity for this purpose. 

The Council will need to share this information with other bodies who have a statutory duty in the management of flood risk such as the Environment Agency and Thames Water. This helps us all gain a clear picture of those affected and can work better together to reduce the risks and prioritise resources and fulfill statutory duties. 

The Lead Local Flood Authority team in Camden will also be collating information from other services that manage council land or highways, as well other organisations involved in events.
 

Flood Risk Management

Flood risk

Camden is not at risk of flooding from the Thames or any other open rivers.

The main risk of flooding within the borough is from surface water after significant rainfall events, and incapacity in the combined sewer to remove rain water. Groundwater flooding is also a growing issue in Camden.

There have been three significant surface and sewer flooding events in Camden in the past 40 years. The first occurred in August 1975, the second in August 2002 and the third in July 2021. All events were caused by sudden extreme downpours.

What are we doing?

The Flood and Water Management Act 2010 makes all unitary authorities, including the London Borough of Camden, lead Local Flood Authorities. This means we have overall responsibility for managing flood risk from surface water and ground water in the borough. However we will not be able to stop flooding on our own so we need to work with other organisations as well as residents and businesses to help us manage flood risk. Two of the most important local stakeholders are Thames Water and the City of London Corporation. for more information on how the council is managing flood risk please download our strategy document below.

Flood Risk Maps

In accordance with the Flood Risk Regulations, maps showing the flood risk from rivers, reservoirs and surface water runoff have been published on the Environment Agency website. The maps for river and reservoir flooding (including that from the Hampstead Heath ponds) have been published before but this is the first time surface water risk has been included.

If you have any concerns about anything to do with the maps, please contact Green Camden at: greencamden@camden.gov.uk

What we are doing to manage the risk of flooding in the borough

We will:

  • Deliver on the actions identified in the London Borough of Camden flood risk management strategy
  • Record flood incidents to improve our understanding of flood risk
  • Investigate flooding incidents to determine the causes. If you have been flooded internally please email greencamden@camden.gov.uk and we will get in contact with you
  • Maintain a public register of structures and features that are likely to have a significant effect on flood risk in Camden
  • We are a statutory consultee for all major planning applications with reference to Sustainable Drainage Systems (SuDS) proposals and flood risk
  • Other organisations also have roles to play in managing flood risk, as do residents themselves. More information about this can be found on our flood risk page

Flood Asset Register

Camden Council is obliged to produce a register of all assets it believes pose a significant risk to flooding.

The register focuses on the drainage assets in, or impacting on, the areas of greatest flood risk (see map below) as well as any major features. An asset being on this register does necessarily not mean that its failure by itself will cause problems but that it could add cumulatively to the risk and hence we are monitoring its condition.

Flood Risk Map 

This register will continue to grow as more information comes in. If you have any questions about it, or wish to see a copy of the register, please contact the Lead Local Flood Authority: greencamden@camden.gov.uk

Flood Risk Consultations

Flood Risk Management Plan

The public consultation for Cycle Two of England’s Flood Risk Management Plans (FRMP) is currently  live. Camden sits in the Greater London Flood Risk Area in relation to surface water flooding. We have worked with the Environment Agency to propose local measures for the Thames Basin FRMP. To view the draft Plan and respond to the document, visit the Environment Agency’s consultation page.

(Open 22 October 2021 - 21 January 2022)

Flood Risk Management Strategy

Upcoming consultation (open to be confirmed).

Flood Investigation Report - July 2021 Floods

Camden's Flood Investigation Report into the July 2021 Floods

In July 2021, Camden experienced surface water and sewer surcharge flooding affecting streets and properties. The extent of the flooding triggered a requirement for the Council to complete statutory Flood Investigation Report. 

The report outlines the impacts of the floods, the main factors that contributed to the flooding as well as recommendations on what can be done to limit the impact of future flooding.

Camden appointed AECOM to complete the Flood Investigation report which was produced in consultation with residents, neighbouring local authorities and partners including Thames Water, the London Fire Brigade and the Environment Agency.

The findings and recommendations of the Flood Investigation Report will be incorporated into a new Flood Risk Management Strategy for Camden which will be published for consultation in the late summer.
