This edition starts with the landscape of the Natural History Museum and the revolution in SuDS. It revisits the esplanade at Dover; indulges in the joys of tidal swimming; and explores the infrastructure of water. We examine water management as part of HS2’s construction and navigate the Woodberry Wetlands and the Lea Valley Ice Centre. The research section looks at specifying trees and a project that evaluates the quality of soil used in the Queen Elizabeth Olympic Park.
