The Cubic Mile project : workshop overview

The City of London Corporation and the British Geological Survey (BGS) hosted a workshop to conclude the ‘Cubic Mile’ project, an embedded researcher project carried out between November 2021 and October 2022. Focusing on the City of London (Figure 1), the year-long partnership investigated how urban subsurface space could be better utilised to improve the City’s resilience to the impacts of long-term climate change and extreme weather. The workshop event brought together a range of stakeholders to discuss the progress of this project over the past 11 months, and to develop recommendations and next steps in the understanding, and potential development, of the urban subsurface for climate resilience. The project aimed to identify the current gaps and uncertainty in subsurface use and associated data, focussing on five potential subsurface adaptation measures: • Urban greening and tree planting • Sustainable drainage systems (SuDS) • Cool spaces below ground • Ground source energy • Resilience of buried utilities networks This document provides a summary of key findings and recommendations from the workshop, as well as a more detailed insight into issues raised during the discussions. Further background information on the project, as well as more information on climate resilience, is available on the UK Climate Resilience Programme website: https://www.ukclimateresilience.org/projects/climate-action-strategy-for-city-of-london-adaptive-design-pathways-for-londons-cubic-mile/
