The updated Sustainable Drainage Systems (SuDS) standards, introduced by DEFRA in 2025, mark a clear shift from design guidance to performance-based evidence. Developers and designers must now show, not just state, that rainfall is managed on site during both everyday and extreme events.

Gwynedd Council has been awarded a significant Natural Flood Management (NFM) accelerator grant from the Welsh Government to progress flood mitigation in two catchments: Criccieth on the Llŷn Peninsula and Waunfawr in the foothills of Eryri.

Catchment-based planning plays an increasingly important role in municipalities and cities as stormwater management and climate adaptation require a more holistic perspective.
