As the local lead authority for flood management, Southwark Council has a statutory responsibility to manage the flood risk in our area. They are working closely with Thames Water and local stakeholders to identify investment opportunities to reduce the likelihood of flooding, primarily for surface water flooding to which this area is prone. The most notable recent surface water flooding event was in April 2004.
Southwark has also launched community engagement initiatives to reduce the impact of flooding, and TRRA and BRRA have agreed to formulate a pilot community flood plan for our immediate area to reduce the impact of surface flooding. A small team is working on this with support and we anticipate funding from the Greater London Authority. The community plan will be communicated via our new web site and if it is successful it will be a model for elsewhere in Southwark and London.
In the meantime there is a need for all of us to be vigilant about the flood risk especially at this time of year with leaf fall. Please ensure gullies and drains outside your house are clear to avoid pools of water in the street in times of heavy rain – this last happened on Sunday 4th November am. Avoid blocking drains with vehicle wheels. After the 2004 flood, the council installed extra gullies in the road and the gullies are subject to regular maintenance. If you have any concerns about the gullies or leaf clearance please contact the Southwark Environment helpline on 020 7525 2000 but during a rainstorm it is quickest for us to clear the gullies ourselves.
In order to maximise chances of funding for major alleviation projects, Thames Water and Southwark are collating evidence about the impacts of flooding events in Dulwich and would be very pleased to receive copies of photos and reports from residents about the impact of the 2004 flood or any subsequent household drainage investigations. If you are able to help, please let us know.
