London Sustainable Drainage Proforma

From April 2019, all 33 London Lead Local Flood Authorities (LLFAs) will introduce the London Sustainable Drainage Proforma. This proforma will be required to accompany Sustainable Drainage strategies submitted with planning applications and will form part of planning application validation requirements.

The proforma sets a clear standard for the information that should be provided in a Sustainable Drainage strategy for all development in London. The proforma is intended to ensure that key information is provided with the initial planning application, reducing the need to request additional information throughout the assessment process and preventing delays in approval.

This initiative is supported by the Greater London Authority (GLA) and the London Drainage Engineers’ Group (LoDEG).

For more information and to download the proformas, please visit: the London Sustainable Drainage Proforma web page

Coming Soon 

To support the initiative, Innovyze is set to publish a 'how to' guide showing where in MicroDrainage to find the information to complete the proforma. More details to follow.
