In urban landscapes, concrete and other impermeable surfaces, together with the removal of vegetation, results in increased surface water run off.
The growing trend to pave our driveways and front gardens allows rainwater to be quickly directed into drainage systems, which during heavy rain and storms can cause local flooding.
Rain gardens are landscaped areas, designed to help slow down surface water run off, reducing the rate at which it enters the surface water drainage system. In turn, this helps to reduce the risk of flooding.
Rain gardens were first developed in the United States in the 1990s and are a popular approach to flood prevention.
We have compiled a handbook to help you create your own rain garden. As well as helping to prevent flooding, rain gardens can make attractive features in front or rear gardens that also benefit wildlife and attract bees and other pollinating insects.
