Surface Water Drainage Assessment
Surface water run-off needs to be managed to ensure it doesn't flood the development or cause downstream flooding.
Therefore every planning application needs a Drainage Assessment that identifies how the surface water will be managed.
We have created an online tool which will help you work out what you need to submit as part of the validation process for your planning application.
Anyone wishing to submit a planning application should use the online tool to help make sure their application can be validated quickly and easily.
