The second edition of this case study highlights the impact of concrete block permeable paving as an irrigation source, sustaining street trees and green infrastructure, following a site visit some 5-years after completion. Its low-intervention, thin overlay technology enables sustainable reuse of conventional road bases and their embodied carbon, creating attractive, safe shared-surfaces. Capturing rainwater runoff straight from the surface without gulleys, the permeable paving overlays provide a gradual flow of clean water laterally into raingardens or basins, for storage and irrigation.
This project is a sustainable drainage (SuDS) park with community at its heart and an exemplar for future urban landscapes. The scheme won ‘Winner of Winners’ (the President’s Award) as well as Winner of the ‘Adding Value through Landscape’ category at the 2017 Landscape Institute Awards, and also an ICE London Civil Engineering Award 2016.
