Street trees have a crucial role in climate resilience, water quality and surface water management, traffic calming, sustainable travel and more. The National Policy Planning Framework, the National Model Design Code, and Homes England’s Streets for a Healthy Life all advocate for, or legally require street trees. On the other hand, cash and time pressed highway officers are concerned that the retention, integration and management of trees diverts attention from their primary tasks and impacts on their budgets. This session explores some of the issues to consider how we can collaborate for long-term success.
