As climate change brings more intense and unpredictable rainfall, sustainable drainage systems (SuDS) are gaining increased attention as a flood risk management strategy, while providing other additional benefits too. SuDS offer on-site storage of rainwater and surface runoff to reduce the risk of system overload and localised flooding. These systems are not only functional but can also provide educational, aesthetic and sensory benefits. Features such as rain gardens, swales and planters can enhance outdoor spaces by improving amenity value, while also supporting climate resilience and biodiversity.
RAB were recently appointed by Redcar and Cleveland Borough Council (using funding from the Department for Education) to explore how SuDS could be used to enhance 10 schools across their borough. Each of these schools had reported problems with flooding, impacting key areas where school children learn and play. The goal of this scheme was to design possible SuDS solutions to increase the storage capacity of rainwater on site to allow for attenuation of water before it can drain. Where possible, proposed features aim to deliver not only drainage benefits, but also sensory-rich, interactive elements that encourage outdoor learning. These spaces can offer educational benefits through supporting the understanding of natural processes such as infiltration and biodiversity.
Site visits were completed over three days by Peter Batty, Beth Irwin-Jones and Steve Brannen. They engaged directly with resident caretakers and headteachers on site to understand the specific drainage challenges faced at each location to inform a tailored report for each school, outlining potential SuDS interventions. The proposed designs make use of existing features to minimise disturbance, reduce costs and maximise functionality of the current outdoor spaces, which may have previously been disused due to flooding. Many of the designs include interactive, dual-purpose elements such as rain gardens or planters, that provide both water attenuation and engaging educational and sensory features. This transforms previous problem areas to dual purpose areas. ArcGIS mapping software was used to visually display each proposal in context on site plans.
This initial scoping and design work lays the foundation for the next phase of the project; to develop these designs to ensure they are appropriately sized, cost-effective and fit for purpose. As a part of this stage, RAB Consultants also identified key site-specific constraints such as access, existing infrastructure and drain depths, and provided indicative costs to help inform funding requirements.
RAB are proud to have played a role in setting this process into motion, supporting these schools in becoming more resilient to the increased rainfall brought by a changing climate and ensuring vital education and play areas are protected and enhanced.
RAB deliver a wide range of flood risk management and resilience services for both public and private sector organisations.
