Rain Garden at Cressingham Gardens Estate

December 2, 2014

Yesterday, I went along to see work begin on what will be Lambeth’s biggest rain garden.

Currently, water from three downpipes on the estate runs on to a grassed area and then makes its way down and out on to Tulse Hill. During heavy rainfall, a significant amount of water flows down to the road. The garden will help to reduce this by retaining the water and allowing it to slowly soak into the soil.

How does a rain garden work?

The first day


1. We started by marking out the areas for digging. There are three sections and each sits directly under a downpipe.


2. We then carefully removed the turf and placed this to one side to be used later on the berms, or garden walls.


3. Once all the turf had been removed, the hard work really started and we began digging out the gardens. We removed a lot of clay which will have added to the current drainage problems. The remaining earth will be mixed with compost to improve drainage and placed back into garden over a layer of gravel.

Despite the very best efforts of staff and volunteers, we didn’t manage to dig out all of the gardens in one day. Work will continue at a later date and a planting session (which will be rather less strenuous!) will be arranged in the near future.

If you would like to get involved in future sessions, please contact Helen Spring at the Lost Effra Project hspring@wildlondon.org.uk.

We’ll keep you up to date with this project and really look forward to seeing the finished gardens.

Help us to shape how we manage flood risk in Lambeth

Did you know that approximately 46,000 residential and non-residential properties in Lambeth have been identified as being at particular risk of flooding? The flood risk comes from surface water runoff, groundwater and small watercourses and ditches.

We are now the Lead Local Flood Authority for the London Borough of Lambeth and have a responsibility to lead and co-ordinate local flood risk management.

We have devised a new draft Flood Risk Management Strategy which outlines the priorities for local flood risk management and provides a delivery plan to manage the risk over the next five years.

It outlines our aims for managing flood risk, including:

  • ¬†Improving knowledge and understanding of local flood risk
  • Using available information on flood risk to predict flooding and issue warnings
  • Increasing awareness of flooding
  • Working in partnership with Risk Management Authorities, communities and businesses
  • Encouraging and implementing sustainable drainage solutions
  • Ensuring that planning has a positive or nil effect on flood risk

We would like your feedback!

The draft Lambeth Flood Risk Management Strategy and guidance for residents can by found on our website. You can leave feedback by completing on our online survey.

The survey will take approximately 10 minutes to complete and your feedback will help us to shape how we manage flood risk in Lambeth in the future.
