To reduce flood risk and improve urban resilience through a connected network of rain gardens, while enhancing biodiversity, air quality and community wellbeing.

The project includes the design and delivery of a borough-wide network of rain gardens, tree pits and planted SuDS features. It involved detailed site analysis, coordination with highways and transport teams, and multiple phases of installation across the Coppermill area. Community engagement and planting formed a key part of the delivery, alongside ongoing stewardship initiatives.

The Coppermill scheme uses nature-based drainage to manage rainwater where it falls. By combining planting, soil systems and carefully designed layouts, the rain gardens slow, store and filter runoff from surrounding streets – reducing pressure on drainage systems while creating attractive, usable green spaces.

The Coppermill rain gardens demonstrate how SuDS can go beyond drainage – delivering environmental, social and health benefits at a neighbourhood scale.
