A UK Government research paper concludes that Nature-based Solutions such as floodplain reconnection, riparian woodland and leaky barriers are most effective when planned and modelled across whole catchments rather than as isolated site schemes. The study stresses integrating NbS with existing hard defences, using hydrological and hydraulic modelling to quantify peak flow attenuation and downstream level reductions under design storm events. For civil and drainage engineers, this points to earlier basin-scale option appraisal, multi-landowner agreements and long-term monitoring of storage volumes, infiltration rates and sediment behaviour.

A former Ibstock extraction site, Dalton Quarry, is being converted by Green Earth Developments Group into a biodiversity “bank” of engineered habitats to generate tradable biodiversity net gain (BNG) units for UK infrastructure schemes. The project will create a mosaic of habitat types on previously worked quarry land, allowing developers to purchase pre-accredited BNG units rather than delivering all ecological uplift within constrained project footprints. For civil and geotechnical teams, this model could influence land-take, earthworks design and long-term aftercare obligations on major road, rail and housing projects.

National Highways has appointed WSP to lead a multi-disciplinary team to deliver its Water Quality Plan targeting pollution from road run-off across the strategic road network. The commission will focus on identifying high-risk outfalls, retrofitting drainage and treatment assets such as interceptors, swales and attenuation ponds, and improving monitoring of contaminants including hydrocarbons and suspended solids. For civil and geotechnical designers, the move signals more retrofit water treatment structures at existing junctions, cuttings and embankments, with tighter controls on discharge consents.
